ASP.NET Graphs: Raise the Bar
They say that a picture is worth a thousand words, and nowhere is this more evident than in the use of bar charts.
With bar charts, it’s possible to visualize past sales history, forecast stock prices, and display survey results pictorially — among literally thousands of other applications. Bar charts become even more valuable when they can be generated dynamically. Thankfully, ASP.NET provides the means for doing just that within the existing .NET framework, via the
SYSTEM.DRAWING namespace.
In this tutorial, we’ll:
- Examine some of the classes and methods of the
SYSTEM.DRAWINGnamespace.
- Learn how to determine the coordinates of an object.
- Examine the code that’s used to dynamically generate a bar chart like the one shown below.
You might be interested to know that the above image file was made using the code we’ll explore in this tutorial, with one slight modification. More on that later.
Before we begin, you might like to download the code that we’ll use in this article.
The
System.Drawing Namespace
The
SYSTEM.DRAWING namespace provides access to basic graphics functionality that allows us to draw dynamic images, and is the basis on which we’ll build our bar chart. We’ll use the following classes:
Bitmap– This class is used to create the bitmap image.
Graphics– This is the surface that contains all the individual objects that comprise our bar chart.
SolidBrush– This class defines a brush of a single color. Brushes are used to fill graphical shapes, which, in the case of our bar chart, will be rectangles.
Pen– Pen defines an object that’s used to draw lines and curves.
We’ll also use a number of methods within the
SYSTEM.DRAWING namespace:
Clear– This method clears the entire drawing surface and fills it with the specified background color. Its only parameter is the Color object, which specifies the color that we want to paint the background.
FillRectangle– This method uses a brush to fill the interior of a shape. This is the method we’ll use to color-fill the background color of our bitmap, the background of the chart area, and the chart bars. The parameters it uses are brush, the X and Y coordinates of the upper left corner of the rectangle, and the width and height of the rectangle.
DrawRectangle– This is the method with which we’ll draw a border around the bitmap, bar chart area, and the chart bars. The parameters it uses are brush, the X and Y coordinates of the upper left corner of the rectangle, and the width and height of the rectangle.
DrawLine– This method is used to draw the horizontal scale lines. The parameters it uses are the pen that was used to draw the line, the X and Y coordinates of the line’s starting point, and the X and Y coordinates of the line’s end point.
DrawString– This method draws text objects on our image. The parameters it uses are the text string that we want to draw, font information, the brush it uses, and the X and Y coordinates of the upper left corner of the drawn text.
Determining the Coordinates of an Object
Determining the X and Y coordinates that position each of the objects in our image is a topic that deserves special attention, since it has the potential to cause the biggest problems in our drawing. Unlike the information you may recall from your high school geometry class, the home coordinate — or (0,0) position — in .NET is actually located in the upper left corner of the display. Furthermore, position plotting is zero-based; that is, a rectangle that’s 200 pixels wide and 400 pixels high, for example, will have X coordinates that range from 0 to 199, and Y coordinates that range from 0 to 399.
Take a look at the image below, which shows the coordinates of each corner in our 200 x 400 rectangle.
Now, if we wanted to draw a line from the lower left corner of our rectangle to the lower right corner, we would plot two points: (0,399) and (199,399). This information will be useful when we determine the coordinates and dimensions of the shapes that comprise our chart.
The Code to Generate our Bar Chart Image
We designed all the dimension and positioning constants in a way that would allow the proportion and scale of our drawing to change as those values change. For example, the height and width are set to 450 and 400, respectively, in our sample program. If we were to change those values to, say, 850 and 1125 respectively, the height and width of our bars would change, as would the other elements in our chart.
Before we dive into the code, let’s examine the global values it uses:
BMP_HEIGHTand
BMP_WIDTHare the dimensions of the bitmap image.
CHART_LEFT_MARGIN,
CHART_RIGHT_MARGIN,
CHART_TOP_MARGINand
CHART_BOTTOM_MARGINdefine the margins between the outside border of our bitmap and the border around the chart area.
CHART_HEIGHTand
CHART_WIDTHare the dimensions of the chart area.
SCALE_INCREMENTprovides the increment of horizontal scale lines on the bar chart.
BAR_LABEL_SPACErepresents the amount of space, in pixels, between the top of each bar on the chart, and each bar’s label.
LINE_COLORis the constant object that defines the color of lines and borders around various objects.
TEXT_COLORis a constant object that defines the text color for the horizontal scale labels and bar value labels.
barValueis an integer array that contains the values of the bars that are drawn on the bar chart.
bitmapis a class that’s used to create the bitmap image.
chartis the graphics class that’s associated with our bitmap image. It represents the surface onto which all the objects of our bitmap will be placed.
Now, on to the code! In some cases, the code in this tutorial has been formatted differently than the download code, so that it can conform to web display requirements.
Dim bitmap As New Bitmap(BMP_WIDTH, BMP_HEIGHT)
Create an instance of our
Bitmap class and set its dimension to the constants,
BMP_WIDTH and
BMP_HEIGHT.
Dim Chart As Graphics = Graphics.FromImage(Bitmap)
Create an instance of the
Graphics class that’s associated with our
Bitmap image. This is the surface onto which all other objects for our bitmap will be placed.
barValueis an integer array that will be used in drawing the chart bars, and is populated via the
GetBarValues()function (below):
Function GetBarValues()
barValue = New Integer() {18, 45, 163, 226, 333, _
3, 183, 305, 329, 73, _
271, 132, 348, 272, 64}
Return barValue
End Function
Note that these values are hard-coded for the sake of keeping our code as simple as possible. However, they could just as easily be replaced with database data, form data, or data passed into our program via query string.
The next section of code comprises a series of variables that are used to define the dimensions and locations of certain objects on the chart.
numberOfBars = barValue.Length
numberOfBarsis the size of the integer array containing the bar values. Its main use is in determining the width of the chart bars. I could just as easily reference the
barValuearray length directly using its definition,
barValue.Length. However, this variable is used to help our understanding of the code.
highBarValueis the highest bar value that appears on the chart, and is defined by the following function:
Public Function GetHighBarValue(ByVal numberOfBars As Integer, _
ByVal barValue As Integer(), _
ByVal highBarValue As Integer)
Dim i As Integer
For i = 0 To numberOfBars - 1
If barValue(i) > highBarValue Then
highBarValue = barValue(i)
End If
Return highBarValue
End Function
This function loops through the bar value integer array and sets the
highBarValuevariable to the highest value in the array.
maximumScaleValueis the highest scale value along the Y axis, and is defined by the function
GetMaximumScaleValue. Let's examine each of the statements in this function.
maximumScaleValue = Math.Ceiling(highBarValue / scaleIncrement) * scaleIncrement
This statement calculates the highest multiple of the scale increment for the chart. In our example, the scale increment is 50 and the highest bar value is 348. Therefore, the maximum scale value is 350.
If (maximumScaleValue - highBarValue) < BAR_LABEL_SPACE Then
maximumScaleValue += scaleIncrement
End If
If the highest bar is too close to the top of the chart, its label will sit above the chart area of our bitmap. To prevent this from happening, we'll need to increase the maximum scale value by one additional scale increment. Going back to our sample chart again, we recall that the maximum scale value was calculated as 350. Our high bar value is 348, which is only 2 points away from the top of the chart area. We want the top bar value to be at least 15 points (the value of
BAR_LABEL_SPACE) from the top of the chart, so we need to increase the maximum scale value from 350 to 400:
numberOfHorizontalScaleLines = maximumScaleValue / SCALE_INCREMENT
The number of horizontal scale lines is used as an index when the scale lines are drawn on the chart. To define it, we divide the maximum scale value by the scale increment. The total number of scale lines is also used to calculate the vertical scale ratio, which is discussed next.
verticalScaleRatio = CHART_HEIGHT / numberOfHorizontalScaleLines
verticalScaleRatiois the factor that ensures that the vertical positioning of the horizontal scale lines is proportional to the height, in pixels, of the chart area.
verticalScaleRatiois calculated by dividing the chart's height by the number of horizontal scale lines in the chart.
In our sample program, the chart height is 350 pixels, and it has 8 horizontal scale lines. Thus, the vertical scale ratio is:
350 / 8
or 43.75 pixels. This means that we need to draw horizontal scale lines every 43.75 pixels from the top to bottom of the bar chart.
barHeightRatio = CHART_HEIGHT / maximumScaleValue
In a similar manner to the way in which we calculated the vertical scale ratio for placement of the horizontal scale lines, we need also to calculate the bar height ratio so that the height in pixels of each bar is proportional to the chart's height.
In our example, the bar height ratio is calculated as follows:
350 / 400 = 0.875.
Thus, each bar value will be multiplied by a factor of 0.875.
Next, let's examine the methods that draw the chart elements.
DrawChartBackground
The following color structures are defined for this method:
clearCanvasis the base color of the bitmap image.
bmpBackgroundColoris the background color of the bitmap image.
chartBackgroundColoris the background color of the chart area. It represents the area onto which the chart bars and their labels will be placed.
Chart.Clear(clearCanvas)
The above method clears the entire drawing surface and fills it with the color specified by the color
clearCanvas.
Chart.FillRectangle(bmpBackGroundColor, 0, 0, BMP_WIDTH, BMP_HEIGHT)
This method sets the background color of the bitmap and establishes the chart's width and height.
Chart.DrawRectangle(LINE_COLOR, 0, 0, BMP_WIDTH - 1, BMP_HEIGHT - 1)
The above method draws a border around the entire bitmap.
chart.FillRectangle(chartBackgroundColor, _
CHART_LEFT_MARGIN, _
CHART_TOP_MARGIN, _
CHART_WIDTH, _
CHART_HEIGHT)
chart.DrawRectangle(LINE_COLOR, _
CHART_LEFT_MARGIN, _
CHART_TOP_MARGIN, _
CHART_WIDTH, _
CHART_HEIGHT)
The code presented here color-fills, and draws a border around, the chart area of our bitmap. Since all the elements of our bitmap must fit inside the outermost bitmap dimensions, we need to make room within the bitmap for the elements outside of the chart area. Our example displays only scale numbers in this area; however, you may wish to add other elements as you customize the code to suit your needs.
DrawScaleElements
The following constants are defined for this method:
SCALE_Xis the X coordinate of the scale label.
SCALE_Xis defined as 25, which is used to locate the X coordinate 25 pixels to the left of the chart's left margin.
SCALE_Yis the Y coordinate of the scale label at the top of the chart. It is defined as 5 pixels below the chart's top margin, which ensures that the scale labels are centered vertically with respect to the horizontal scale line.
iis the index variable that tracks our iterations through the loop.
For i = 1 To numberOfHorizontalScaleLines - 1
chart.DrawLine(LINE_COLOR, _
CHART_LEFT_MARGIN, _
CHART_TOP_MARGIN + (i * verticalScaleRatio), _
CHART_LEFT_MARGIN + CHART_WIDTH, _
CHART_TOP_MARGIN + (i * verticalScaleRatio))
This loop draws the horizontal scale lines. Note that, here, we're drawing only the interior scale lines, as the top and bottom lines were created when we drew our border around the chart area. The starting X coordinate represents the chart's left margin; the ending X coordinate is derived from a formula that calculates the position of the right-hand side of the chart area. The starting and ending Y coordinates are both the same, and are calculated on the basis of the distance between the chart's top margin and the current scale line.
For i = 0 To numberOfHorizontalScaleLines
chart.DrawString(maximumScaleValue - (i * SCALE_INCREMENT), _
New Font("arial", FontSize.Large, FontStyle.Regular), _
TEXT_COLOR, _
SCALE_X, _
SCALE_Y + (i * verticalScaleRatio))
This loop draws the scale labels. The Y coordinate of the scale label is calculated similarly to the way that we calculated the scale lines' positioning.
DrawChartBars
This method uses the following elements:
columnSpacingis the variable that's used to increment the horizontal spacing between each bar on the chart.
currentBarHeightis the adjusted value, in pixels, of each individual bar, so that each bar is proportional to the height of the chart (see the previous discussion on this point).
barWidthis calculated on the basis of the chart's width and the number of bars it's intended to display.
fillColoris an array of
SolidBrushobjects that's used to define the bar colors.
numberOfFillColorsdefines the number of array elements in the
fillColorarray. It's used as a counter to determine which color each bar should take.
iand
jare index variables.
columnSpacing = barWidth
This statement initializes the column spacing before the chart's bars are drawn.
For i = 0 To numberOfBars - 1
currentBarHeight = Convert.ToSingle(barValue(i)) * barHeightRatio
chart.FillRectangle(fillColor(j), _
columnSpacing + CHART_LEFT_MARGIN, _
BMP_HEIGHT - CHART_BOTTOM_MARGIN - currentBarHeight, _
barWidth, _
currentBarHeight)
chart.DrawRectangle(LINE_COLOR, _
columnSpacing + CHART_LEFT_MARGIN, _
BMP_HEIGHT - CHART_BOTTOM_MARGIN - currentBarHeight, _
barWidth, _
currentBarHeight)
chart.DrawString(Convert.ToString(barValue(i)), _
New Font("arial", FontSize.Small, FontStyle.Regular), _
TEXT_COLOR, _
columnSpacing + CHART_LEFT_MARGIN, _
BMP_HEIGHT - CHART_BOTTOM_MARGIN - currentBarHeight _
- BAR_LABEL_SPACE)
j += 1
If j > (numberOfFillColors - 1) Then
j = 0
End If
columnSpacing += barWidth
This loop formats the chart bars. Let's examine each statement individually.
currentBarHeight = Convert.ToSingle(barValue(i)) * barHeightRatio
This statement sets the current bar height so that it's proportional to the height of the chart. (See the previous discussion on bar height ratio for more on this point.)
chart.FillRectangle(fillColor(j), _
columnSpacing + CHART_LEFT_MARGIN, _
BMP_HEIGHT - CHART_BOTTOM_MARGIN - currentBarHeight, _
barWidth, _
currentBarHeight)
This section fills the bar with the appropriate fill color. The X coordinate of the bar's upper left corner is calculated as the sum of
columnSpacing and
CHART_LEFT_MARGIN. The Y coordinate is calculated by starting from the bottom of the bitmap, and subtracting from the Y coordinate value the chart's bottom margin and the current bar's height.
chart.DrawRectangle(LINE_COLOR, _
columnSpacing + CHART_LEFT_MARGIN, _
BMP_HEIGHT - CHART_BOTTOM_MARGIN - currentBarHeight, _
barWidth, _
currentBarHeight)
This code draws the border around the chart bar. This method uses the same calculations as the
FillRectangle method we used for the X and Y coordinates of the upper left corner of the bar.
chart.DrawString(Convert.ToString(barValue(i)), _
New Font("arial", FontSize.Small, FontStyle.Regular), _
TEXT_COLOR, _
columnSpacing + CHART_LEFT_MARGIN, _
BMP_HEIGHT - CHART_BOTTOM_MARGIN - currentBarHeight _
- BAR_LABEL_SPACE)
Draw the label above the bar. The X coordinate in this method is identical to the
DrawRectangle method from the previous statement. The Y coordinate is also similar to the
DrawRectangle method above, except that it also subtracts
BAR_LABEL_SPACE from the calculation so that the label will sit above the bar.
j += 1
If j > (numberOfFillColors - 1) Then
j = 0
End If
This code block ensures that the bar fill colors are repeated.
columnSpacing += barWidth
Finally, this statement increments the
columnSpacing variable so that the next bar is positioned alongside the previous one.
The Finishing Touches
Response.ClearContent()
This method clears all the content from the output buffer. This code ensures that the only output that's sent to the browser is our image.
Response.ContentType = "image/gif"
bitmap.Save(Response.OutputStream, Imaging.ImageFormat.Gif)
The first of these statements sets our image type to
.gif. The second statement sends our image directly to the browser. If we wanted to send our image to a file instead of to the browser, we'd use the following code:
Response.ContentType = "image/png"
bitmap.Save("C:pathtobargraph.png", Imaging.ImageFormat.Png)
You'll need to change the value of
"C:pathtobargraph.png" to reflect the desired filename and path for your file. Note that when we run our page with these two statements, instead of the previous two, a blank page will display. However, if you look into the directory in which you specified the file to be saved, you'll find the image has been created as a file that you can open in your favorite graphics software.
chart.Dispose()
bitmap.Dispose()
This last snippet releases the memory used by the
Graphics object and the bitmap.
Summary
In this tutorial, we examined some of the classes and methods that are available within the
SYSTEM.DRAWING namespace, learned how to determine the coordinates of an object, and used these skills to draw a basic bar chart.
So, where do we go from here? With the skills you've acquired from this tutorial, you can easily add a report title, x-axis labels, and a legend to our sample chart. The
SYSTEM.DRAWING namespace offers a number of methods that will enable you to create a range of other charts -- a pie chart is just one example. Using the advanced two-dimensional graphics functionality of the
SYSTEM.DRAWING.DRAWING2D namespace, you can create charts with stunning visual appeal. I would encourage you to examine all the available namespaces and methods, see what they can do for you, then really let your creative juices flow!

An EditableWebData represents an Editable value, along with WebData.
Similar to the example in Gizra/elm-storage-key lets imagine a Todo list that can be edited. And lets assume that while a todo item is being edited, or while it's being saved, we'd like to keep showing the original value.
Here's a pattern we may use to solve this:
import EveryDictList import StorageKey type alias TodoItem = String {-| Wrap our `TodoItem` with `EditableWebData`, thus making it have the ability of having an "original" vs "new" values, and also maintain the `WebData` state. -} type alias EditableWebDataTodoItem = EditableWebData TodoItem {-| The TodoItem ID is type safety. -} type TodoItemId = TodoItemId Int {-| We wrap the `ArticleId` with the `StorageKey`. -} type alias StorageKeyTodoItem = StorageKey TodoItem {-| We use `EveryDictList` as we want to maintain the order of the items. -} type alias EveryDictListTodoItems = EveryDictList StorageKeyArticle EditableWebDataTodoItem type alias Todo = { label : String , items : EveryDictListTodoItems }

Building a Strawpoll clone in Phoenix with channels
Current Versions
Elixir: v.1.1.0
Phoenix: v1.0.3
Ecto: v1.0.6
Introduction
One of the things that interested me the most about Phoenix and Elixir is the capabilities that are available for real-time data synchronization and broadcasting with things like Websockets. It has become such an alluring part of Phoenix that chat applications have affectionately become Phoenix’s “hello world” example, even! The reason for this is two-fold: channels are a first-class citizen in Phoenix, so adding them does not require working AROUND the framework, and they’re so simple to add that knowledge isn’t a barrier to implementation either. Based on that, let’s implement our own coming-of-age application in Phoenix too!
What is Strawpoll?
Strawpoll is a realtime polling platform written in nodejs that also takes advantage of websockets. As each vote comes in, the vote is broadcast to everyone who has that poll window open and has voted. So we have a few real time concepts to deal with: receiving broadcasts when someone else votes and sending out broadcasts when we vote, as well as how the polls are modified when they are live (such as closing a poll). It also displays/updates a nice little pie chart on the side of the app in realtime, so we’ll do that too!
Getting started
We need to start with building our Phoenix application, which is a pretty standard and simple process:
mix phoenix.new haypoll
cd haypoll
mix ecto.create
iex -S mix phoenix.server
If everything worked, you should be able to visit and see the standard Phoenix “Getting Started” page!
Setting up our data model
Let’s discuss what we will need from a data perspective. We want to make sure we’re persisting these polls and votes. For our polls, all we really need is the name of the poll and whether it’s still open for voting or not.
> mix phoenix.gen.html Poll polls title:string closed:boolean
As the command states, we need to modify web/router.ex to add the new resource path:
web/router.ex:
scope “/”, Haypoll do
pipe_through :browser # Use the default browser stack
get “/”, PageController, :index
resources “/polls”, PollController
end
Finally, we’ll cap it off by running mix ecto.migrate and make sure that our new table is added with the appropriate columns! Now, let’s create our concept of entries:
> mix phoenix.gen.model Entry entries title:string votes:integer poll_id:references:polls
We don’t want to create full templates and controllers and everything for entries since they don’t really exist much on their own; they really just exist for the purpose of serving data for the polls. We also set up a reference relationship between polls and entries. Once again, run mix ecto.migrate and verify the results. This will set up the “belongs_to” relationship on entries back to polls, but not the other way around. Let’s do that really quick. In web/models/poll.ex:
schema “polls” do
field :title, :string
field :closed, :boolean, default: false
has_many :entries, Haypoll.Entry, on_delete: :delete_all
timestamps
end
Not only do we specify the “entries” association, but we also specify some behavior for when a poll gets deleted that will delete all of the entries that were attached to that poll.
We also need to modify our web/models/entry.ex model to specify a default value for the number of votes to start at 0.
schema “entries” do
field :title, :string
field :votes, :integer, default: 0
belongs_to :poll, Haypoll.Poll
timestamps
end
Finally, restart your server that’s running via iex to make sure it grabs these changes.
Making our poll creation a little more dynamic
Right now our poll creation page is a little static, and there’s no way for us to modify the list of entries available to our poll.
This is a good first start but we can improve it! Let’s make it so that we can add/remove entries from this page and create the poll and associated entries. There’s going to be a lot of javascript work involved here, so we’ll start with our list of dependencies.
Preparing our javascript dependencies
To make this pretty simple, we’ll just use jquery to modify our dom on the fly. To get jquery installed on a global level, we’ll just use a CDN to load the jquery library, and we’ll make it accessible to our entire application via our application layout. Open up web/templates/layout/app.html.eex and add the following:
</div> <! -- /container -->
<script src=”//code.jquery.com/jquery-1.11.3.min.js”></script>
<script src=”<%= static_path(@conn, “/js/app.js”) %>”></script>
Next, we’ll need to add a simple list of entries and a way to add a new entry to our poll form. In web/templates/poll/form.html.eex:
We’ve added a new section with a header of Entries and a button to add more entries. We’ve also added our initial template with a text input for creating a new entry with a particular title.
It’s not super pretty, but that’s okay! We can always clean up a UI later (or pay someone else to do it!). Now, what we want to happen is that every time someone clicks “Add Entry”, the top entry gets copied with a blank value, and if someone clicks the “remove” button next to an entry, it removes that particular row. To do this we’re going to have to write some javascript code. Let’s create a new file that will serve as our workhorse for the Polls page.
Create web/static/js/poll.js:
I’ve commented each line so you can follow along with the javascript code. And then in web/static/js/app.js add the following to the bottom:
import { Poll } from “./poll”
let poll = new Poll()
And clean up the display with some css by adding this to the bottom of web/static/css/app.css:
.entry {
margin-top: 20px;
margin-bottom: 20px;
}
This will spread the entries apart a little bit and it will look ever so slightly better. Now, we need to modify the create action in web/controllers/poll_controller.ex to create the entries with the poll. Start off by adding a line to alias the Entry model with alias Haypoll.Entry:
We have to create a new function to delegate the work and clean up our codebase a little bit, so let’s take a look at line 12 above, the create_poll function. We start off with a call to:
Repo.transaction fn -> ...
This is going to wrap our operation inside of a transaction. If we fail to create an entry or the poll, we want to make sure the whole thing gets rolled back. Next, we just create our standard Poll changeset; nothing exciting here.
We then match on our case for a successful poll insert with the {:ok, poll} tuple. Next, we use Enum.map to call an anonymous function that will build the associated entry for the poll and then insert it. We’re expecting that an errors should fail us out of our transaction, so we use Repo.insert! instead of the standard insert function.
We also match on our case for the {:error, changeset}, where if we fail to insert, we force the transaction to rollback on the changeset. In our create function, we case on the create_poll function instead of our standard Repo.insert. This just makes our logic a little easier to follow and keeps our function a little smaller.
We can create a poll, with entries, but we can’t actually verify that the entries have been created yet. We’ll fix that, however, by modifying our poll show template. Open up web/templates/poll/show.html.eex:
Notice that we also added a hidden input at the top with an id of “poll-id” and a value of the current poll’s primary key. We will need that later! We also add a “data-entry-id” attribute to the list item with a value of the current entry’s id, and wrap the number of votes inside of its own span. We finally add a “vote” class to the Vote button. Save this file now.
Unfortunately, we’re getting a compilation error here about:
protocol Enumerable not implemented for #Ecto.Association.NotLoaded<association :entries is not loaded>
The reason for this is that Ecto will not allow you to shoot yourself in the foot with associations running N+1 queries all over the place. We need to explicitly tell Ecto that we need to preload any associations, so let’s head back to web/controllers/poll_controller.ex and modify the show function:
We define a query to use to fetch our entries which orders by the entry’s primary key. We then feed that query into the poll query, which preloads associated entries via the entry query we wrote. Finally, we use that combined query to fetch a specific poll with a specific id, and feed that all to the show template via our assigns.
Now that we have our UI for polls, it’s time to take it one step further. We’re now going to implement live voting via channels!
Creating and joining a channel
We need to start off by creating the actual channel. We start off working with a couple of common setup details. First, we open up web/channels/user_socket.ex to set up our poll channel and tell Phoenix where to route socket requests/responses through. In web/channels/user_socket.ex, add the following:
channel “polls:*”, Haypoll.PollChannel
And now we need to create our PollChannel module. Open up web/channels/poll_channel.ex:
defmodule Haypoll.PollChannel do
use Phoenix.Channel
def join(“polls:” <> poll_id, _params, socket) do
{:ok, socket}
end
end
We have to set up a “join” function that pattern matches on which channel the user is joining. In our case, we’re creating a channel for each individual poll, so we match on “polls:” <> poll_id. This line is pretty neat; what we’re doing here is pattern matching on a part of a string. We’re expecting the string to start with “polls:”, and then anything following that we’re assigning to the “poll_id” variable. We’re ignoring the params sent in, since we’re not going to use them for anything. Finally, we accept in the socket, since we need to turn around and respond with a tuple of {:ok, socket}.
Next, we need to write some javascript code to demonstrate that we can, at least, join this channel. We’ll save the actual interaction and broadcasting pieces for later. Open up web/static/js/live_poller.js and let’s begin. We’re going to start off relatively simple but build this up later:
Again, I’ve commented all of the code to make it easier to follow along. When we open up the poll show page, we should now expect to see “Connected” and “Joined” show up in our javascript log, and we should not expect to see that on any of the other pages! Now we’re ready to start broadcasting and dealing with messages! Finally, open up web/static/js/app.js and add the following at the bottom:
import { LivePoller } from "./live_poller"
let livePoller = new LivePoller()
Pushing and broadcasting messages
Next, we need to be able to broadcast out when a user votes (and receive the vote as well). We can deal with this via the handle_in function in our PollChannel module.
Here, we’re expecting a broadcast with a message of “new_vote” and expecting to be sent entry_id as one of the parameters. We also are required to pass in the socket. We then fetch the appropriate Entry by the entry_id and then create a changeset that increments the number of votes for that entry by 1. Then, we attempt to update that entry in the database.
If the update was a success, we broadcast out to the socket with a “new_vote” message, supplying an entry_id matching the updated entry’s primary key, and then just respond out with {:noreply, socket}.
If it fails, we send out an error response with a map that includes the reason. If you look back to the javascript code:
.receive(“error”, reason => { console.log(“Error: “, reason) })
Notice that we’re expecting an “error” response (like the :error part of our tuple) and a “reason” in the map for our response! When you tease all of this apart, the whole channel concept really simplifies itself! Now, we have to finish up our javascript code. In setupPollChannel(), after we define our pollChannel, we need to create a new event handler to deal with new_vote messages:
// Set up a handler for when the channel receives a new_vote message
pollChannel.on(“new_vote”, vote => {
// Update the voted item’s display
this._updateDisplay(vote.entry_id)
})
Notice there’s a new function call here, self.updateDisplay. We haven’t written that yet, so let’s do so:
We also reference an “updateEntry” function that we need to define, so let’s do that next:
_updateEntry(li, newVotes) {
// Find the .votes span and update it to whatever the new votes value is
li.find(“.votes”).text(newVotes)
}
Simple function; this is pretty much all just gruntwork to support updating the display and making the UI buttons do things. Finally, we need to write a function that will actually set up the vote buttons and hook them into broadcasting our message. We’ll define one more function: setupVoteButtons.
The only part here that even pertains to the channels is that “pollChannel.push(…)” function call. It pushes a message, in our case “new_vote”, out to the channel with a list of parameters. In our case, the only parameter we actually care about is entry_id! The final contents of our web/static/js/live_poller.js file should look like the following:
Your project is now functional! Not pretty, but functional! You should have live-updating voting numbers, and if you open up multiple browsers, each of your browsers will receive the results live as you go along! And we didn’t even write all that much just to make this project work! Let’s just add one final bit of shiny “interfaceness” to make this project a little more like Strawpoll.
Adding in a live-updating graph
Let’s take it one step further and add in a graph to track all of our votes. For this, I’ll just stick to Google’s graphing/visualization libraries in javascript as they’re pretty simple to understand and implement. I’ll leave it up to you if you want to roll with something a bit different! Let’s start by changing our Poll show template. Wrap the ul inside of a div with a class of “col-xs-8”, and then add another div below all of that with a class of “col-xs-4” and an ID of “my-chart”. We’ll also add a script tag referencing the google jsapi codebase:
<div class=”col-xs-4">
<div id="my-chart"></div>
</div>
<script type=”text/javascript” src=”"></script>
Also, update the <%= entry.title %> line to be wrapped inside of a div with the class of “title”.
<span class=”title”><%= entry.title %></span>
Next, update web/static/css/app.css and add an entry for #my-chart to make it a particular size:
#my-chart {
width: 400px;
height: 400px;
}
Finally, we need to go digging into our live_poller.js code a little more. We’ll start by adding some more code to handle our graph:
Next, at the top of our LivePoller object, add the following line:
chart: null,
And add a call to setupGraph inside the init() function:
// And setup our graph
this._setupGraph()
And in our setupPollChannel function, where you build out the “new_vote” message handler, add the following lines:
// And update the graph, since we have new data
this._updateGraph()
Everything is now complete and we should have a nice new displayed graph that live updates per each vote!
Our final operation is to allow someone to close/reopen polls and broadcast the event appropriately.
Closing and opening polls
In our update function in web/controllers/poll_controller.ex we need to create a new broadcast when a poll is opened or closed!
Haypoll.Endpoint.broadcast(“polls:#{id}”, “close”, %{closed: poll.closed})
Let’s also add a CSS class for something that should be hidden:
.hidden {
display: none;
}
Next, let’s open up the setupPollChannel function in live_poller.js and add a new handler for the “close” message:
// Set up a handler for when the channel receives a close message
pollChannel.on("close", status => {
if (status.closed) {
$("a.vote").addClass("hidden")
$("#poll-closed").text("false")
} else {
$("a.vote").removeClass("hidden")
$("#poll-closed").text("true")
}
})
And finally, update web/templates/poll/show.html.eex to be able to respond to all of this new data:
Our UI should now look like this when someone closes our poll:
Conclusion
We now have a pretty awesome little live-updating live-polling application, and we really haven’t written that much new code, and certainly not complicated polling or socket code. Our application has a very good foundation now, but there are definitely still a few bugs to work out and there are zero tests for this so far! Certainly not ideal, but a great starting point. Here are some of the known bugs:
- We don’t list the entries at all on the Poll edit page
- Anyone can edit/delete any poll
- No tests whatsoever
- The UI/design kind of stinks
If I were to go in and implement all of these, this long post would get much, much longer, so instead I’m going to leave these as exercises to you, intrepid readers!

DavidF: Majority of time spent on last-call issues. Agenda item 6 will be remaining issues. Agenda item 7, issues lacking proposals. Issue regarding IP does not appear on either agenda item, but will be discussed as new charter is published. Status of rechartering: We are a day away from seeing the new charter. Responses from the new charter were requested from AC Reps, and received from all. The new charter is ready, pending announcement of director, perhaps by the end of the week.
No objection to their approval, and no requests for modifications.
[misc notes on actions] Responses trickling back from implementers. Will be published in next day or two. Others have committed but provided no updates. We may have lost HP as an implementer of the specification. Question: Prioritizing dividing the implementations between must, should, etc. Is it the case that we must show two interoperable implementations for every feature, and that we must do it for the musts, and shoulds. Opinion: not required for "should's". DavidF: We have committed to implement not only mandatory but also optional. Noah: We should proceed that way and reevaluate if necessary later. [end of actions]
* Primer -- no report * Spec -- no change from editors * Test collection document Anish: mail sent describing this. Almost done synching with latest version of part 1. Have not started on part 2. Intends to be done by the end of the week. Mike Champion -- WSA -- Hugo wrote something up that will be submitted by the deadline on the 18th. * Attachment feature document -- no comments back on this document yet (LC). Reminder send to chairs list by DavidF. * Last Call issues list -- it is up to date. * Implementation tracking -- status given earlier * Media type draft, nothing to report * Planning for October F2F, please send agenda items. Question: how is list of participants updated? Only 6 registrants had come through in box. It will be updated in next version.
Any pushback to recently-closed issues? Henrik -- a comment regarding closing and whether resolution text was sufficient. This was sent to the chairs list. We have to be careful to say carefully why we closed things. Some of the past closings have contained no rationale at all. Comment received during last call regarding subcode. Gudge proposed not answering the questions. One question was about enumerated fault type, the other was how WSD figures out the type of subcode. Gudge suggests these are not issues for us, but we should bequeath them to the WSD working group. Resolution: No objection. Agreed to send comment to WSD working group. Gudge agreed to send appropriate email to WSD WG in email. Issue 234, are gateways intermediaries? DavidF: Listed as editorial issue, but it is an important concept that needs to be run past the WG. Noah: Agenda statement about issue is an oversimplification, it states there is agreement that a gateway is not intermediary. It may not be, but not necessarily. The wording should not rule out a gateway being an intermediary. Dave Orchard: Should we define gateways quickly, and pass future revisions to WSA working group? Noah: gateways do not appear in SOAP specification. Req??? is fine, it defines intermediary, and talks per-message. We do not talk about gateways, we should not. Proposal: close 354, taking no action except minor editorial. Rational for our position is that a gateway is not necessary a SOAP intermediary, but we are not in the business of defining what is a gateway. Henrik: Agrees. We have nothing to say about these things. We care about what comes in and goes out SOAP. Jean Jacques: Agree with Noah. Mark Baker and I came up with a joint definition for Gateway, to be included in the WSA document." Dave Orchard: So, the direction is to define gateways in WSA? Can we defer this decision for a week, because the WSA WG thread is long and I have not read it? DavidF: We'll record the general feeling of the consensus and postpone decision until next week. Issue 231: DavidF: we have already agreed to a new attribute. The text Noah proposed is the only we have. We can close this issue by incorporating Noah's text. Jacek: Noah's text covers parts of 231. The rest of the resolution regarding 231 is posted in dist-app, recorded in irc, dist app message 193. We have changed the attribute name changed to nodeType, but otherwise we can use Noah's proposed text. DavidF: Is there any objection to closing 231 as just described (and see irc) with the new name of attribute and Noah's text as referenced in agenda? No objections. DavidF: 231 is so closed. John Ibbotson to write closing text to xml-dist-app. Issue 305: DavidF: Editors started preliminary discussion of options resolving 305, URL sent in response to agenda in member archive #12. Marc to outline proposal: Marc: We have three options: 1. Push back on issue -- when we say message, that includes all information, not just the envelope. That ducks the issue a bit. 2. Accept that it is a problem and we need to split http binding into copies of nearly the same thing with different state machines. 3. More radical overhaul. Remove the duplication between http binding text and text of MEPs, pushing MEP descriptions back to section 6, removing tables, extracting descriptive text. Then refer back to the state machines in section 6. Henrik: #3 was proposed in the issue. It is a lot of work, but perhaps we should do it anyway. Other editors state agreement -- setting themselves up for a lot of work. David: Does #3 mean we will have a shorter spec? Marc: Yes, several pages shorter, eliminating redundancies from section 6, which may even be contradictory in places. Shortens http and does not lengthen MEPs much. ???: What about the mail binding, what would be the effect? Does it use response request? DavidF: Are there any major objections to adopting option #3? JohnI: If the editors are willing, I support simplification. Yves: (in response to a question about such changes pushing us back to pre-LC) If the changes are clarifications only, and even though they change the spec's appearance, they will not require us to go back to WD. No objections to adopting option #3. DavidF: There is at leats a tacit mandate at least for adopting option #3. We will leave the issue open until the changes are doneand we can see them, because they are large, and will give an opportunity to catch unintended changes that are beyond editorial. We need the changes by the end of next week. Editors agree. DavidF: We need a stable copy of spec. Any other changes between now and 18th must be there, too. Editors need to do everything for a draft by the F2F that resolves all issues. Editor's question: How should paragraph movements be handled? Text deleted from old section and added to new section. Looks bad. Is there a style sheet to hide this? No. For tables, just leave deleted caption and not entire table. Noah: Marc, is there a fifth change code that could be introduced for notes, like "3 paragraphs removed here". Henrik: Let editors take it off line. Editors instructed to make changes, issue will remain open. Issue 300: Awaiting text from Glen. Postponed. Issue 362.1 DavidF: Request to rename soap encodings ref attribute to idref, to reduce confusion related to other uses of ref, and to better reflect our use. We have a proposal to maintain the status quo noting that if we namespace qualify our attributes, it will appear in a different namespace (the WG agreed to global namespace qualification in a previous issue). DavidF: Proposal, keep the status quo, rationale: now that ref is namespace qualified, it's semantics are uniquely qualified. No objection. DavidF: This part of issue 326 is so closed. Issue 362.2 With regard to how strictly idref is enforced. Spec says we should enforce them. The request is that we MUST enforce them. Proposed resolution: Because we do not mandate XML Schema, such constraint checking is impossible. Noah: Likes proposal, but not the reason. The id could be enforced without schema. But there are other good reasons not to require it. Nothing deeply breaks if we only encourage this and do not mandate enforcement on data that applications are not interested in. DavidF: Any obection to adopting status quo with modified rationale and closing the issue? No objections. DavidF: issue 362 is so closed. Noah will send closing to xmlp-comment and originator. Issue 355: Comment information items in SOAP infoset. DavidF: Gudge was asked to create proposal on what infoset could contain, which he did. There has been a lively discussion. Can someone speak to where the issue is with respect to the discussion (Gudge not present)? Henrik: There was a question involved in signing the envelope, whether an empty header can be removed from the envelope: Noah: Two things, the decision, and the rationale. 1st model: Keep it simple, don't mess with it. 2nd model: It is a bother to keep track of whether data might be missing due to an empty header. Henrik: What if it was an argument. Noah: that was not covered by case. It was not a question of what to do if you remove the last one. Noah prefers 1st option More discussion of specific use cases with intermediaries ... Marc: This (????) would be a significant change to last-call draft, because what was allowed by intermediaries would now be disallowed. Henrik: Correct. Marc: Concerned we need to go back to another draft, which we want to avoid. DavidF: Is there a part of the proposal that we could adopt? Noah: Gudge claimed he took an action item to deal with various aspects, not just CII's. DavidF: There was a specific and a more general discussion. He considered them to be clarifications, but not everyone agrees with that. a. The proposal is large with possible WD size impacts. b. Probably goes beyond CII scope. c. People like where it went. Possible ways forward: 1. Ask Gudge to explain how semantics are not changed. (Henrik points out that intermediaries change, you could say what it applies to) 2. We need another turn of the crank. Either we choose status quo, or ask Gudge or someone to pare down the proposal to just focus on CIIs. 3. We could take Henrik's comment that it really changes things, so decide whether we want to take it on board. Would this change send us back to the beginning of last-call. Yves: Cannot say yes or no. DavidF: Several have called this a major change. What about paring this down. What about dealing with just CII's? Marc: Will we get hit with being signature unfriendly, otherwise? Noah: A middle ground beyond just do comments. Insofar as he is just expressing in infoset terms what we were saying formally, should we allow that. That part is just editorial, but can still go beyond comments. Henrik: Agreed. DavidF: Middle ground, just do CIIs, or a slightly broader proposal to use the infoset terminology and constructions throughout. Noah: do comments and reiterate that editors need to be consistent on infoset, and perhaps it is already clean in that respect. David: Should we go forward? Henrik would like to discover whether this takes us back before LC, to see if more can be done. David: parallel? More discussion... Yves to try finding out by Monday whether this is lilkely to send us back to WD. Henrik to talk to Gudge. -- 366, use generic types for struct and array Proposal to close issue with no action because it is no longer applicable since generics were removed (issue 297). DavidF: Any objections to closing the issue with this proposal? No objections raised. DavidF: issue 366 is so closed. Jean Jacques to write xmlp-comment text. -- 365, keep generics Proposal to close issue with no action because we already decided to remove generics (issue 297). DavidF: Any objections to closing the issue with this proposal? No objections raised. DavidF: issue 365 is so closed.
issues for which we have no proposals. Herve: 277 Henrik: 371 Asir: 363 Jacek: 364 Marc: 294 359, will wait to see what Glen comes up with for 300 which is closely related John Ibbotson & David Fallside: 367 368 369 Proposals due for end of business on Monday.

Okay guys, I managed to get it to compile right and it seems to be working
sweet as. Seems like configure can't find the fam.h file, but what is actually
happening is this
fam.h includes limits.h
limits.h includes the 64bit limits.h

amd64/limits.h attempts to include the compilers limits.h

but for some reason it can't find the file

Someone needs to move on bringing fam 2.7.0-r4 into stable. This problem was
reported and supposedly resolved back in May, and fam stable is still at
2.7.0-r2 for amd64, which has the problem described (and resolved) here. Foser?
'zat your department ??
I just did another amd64 install and tripped on the same problem again, although
emerging fam unstable fixes it.

i know it might be most efficiency, it gives another direction to solve problems. we are using c++, not pure c;
only a container constructer and a stl function is called. have fun guys...
Nice one, my version used an ostream_iterator instead of std::accumulate:
using namespace std; class Solution { public: void reverseWords(string &s) { istringstream iss(s); string word; vector<string> vec; while (iss >> word) vec.push_back(word); ostringstream oss; copy(vec.rbegin(), vec.rend(), ostream_iterator<string>(oss, " ")); s = oss.str(); } };
Yeah, your answer is more delicate ! Previously i do not known "ostringstream oss" can be used in this way "oss.str()". I have learned a new grammar rule.
your answer is so delicate, I'll never known "ostringstring" can be used in this way if didn't find your code

Overview
ZK allows applications to handle events at both the server and client side. Handling events at the server side, as described in the previous sections, is more common, since the listeners can access the backend services directly. However, handling event at the client side improves the responsiveness. For example, it is better to be done with a client-side listener if you want to open the drop-down list when a comobox gains the focus.
The rule of thumb is to use server-side listeners first since it is easier, and then improve the responsiveness of the critical part, if any, with the client-side listener.
Here we describe how to handle events at the client. For client-side UI manipulation, please refer to the UI Composing and Widget Customization sections.
Declare a Client-side Listener in ZUML
Declaring a client-side listener in a ZUML document is similar to declaring a server-side listener, the steps are:
- Declare client namespace first, URI is (aka., client)
- write your logic in JavaScript
Implementation Notes:
- this references to the event target widget.
- Use this.$f() to reference fellow widgets (Widget.$f())
- event is referenced to zk.Event.
For example,
<combobox xmlns:
Notice that EL expressions are allowed in the JavaScript code (for the client-side listener). Thus, it is straightforward to embed the server-side data to the client-side listener. For example,
<window id="wnd" title="main"> <combobox xmlns: </window>
If you want to escape it, place a backslash between $ and {, such as
w:onFocus="zk.log('$\{wnd.title}')".
For more information about manipulating widgets at the client, please refer to the UI Composing section.
Client-side Event Listener First then Server-side
It is allowed to register both the client and server-side event listeners. They will be both invoked. Of course, the client-side listener is called first, and then the server-side listener. For example,
<combobox xmlns:
Client-side Event Controls Firing Behavior
If you want to stop the event propagation such that the server won't receive the event, you could invoke Event.stop(Map). For example, the server-side listener won't be invoked in the following example:
<combobox xmlns:
Since ZK fires an event to the server-side based on the same Event, you can also override event.opts to affect event firing behavior.
Declare a Client-side Listener in Java
The other way to declare a client-side listener at the server is Component.setWidgetListener(String, String). For example,
combobox.setWidgetListener("onFocus", "this.open()");
Notice that it is Java and running at the server.
Also notice that EL expressions are not allowed (i.e., not interpreted) if you assign it directly. It is because EL expressions are interpreted by ZK Loader when loading a ZUL page. However, it is easy to construct a string to any content you want with Java.
Register a Client-side Listener in Client-Side JavaScript
Listening an event at the client could be done by calling Widget.listen(Map, int). For example,
<window> <bandbox id="bb"/> <script defer="true"> this.$f().bb.listen({onFocus: function () {this.open();}}); </script> </window>
where
defer="true"is required such that the JavaScript code will be evaluated after all widgets are created successfully. Otherwise, it is not able to retreive the bandbox (
bb).
scriptis a widget (unlike
zscript), so
thisreferences to the
scriptwidget, rather than the parent.
- Widget.$f(String) is equivalent to Component.getFellow(String), except it is a JavaScript method (accessible at the client).
Register DOM-level Event Listener
Notice that the event listener handling discussed in the previous sections is for handling so-called ZK widget event (Event). Though rare, you could register a DOM-level event too by the use of jQuery (API: jq).

After creating my first game using Unity. I decided to place an interstitial ad to generate some revenue. I use interstitial ad rather than a normal banner ad because I want to utilize full screen of game play and load the ad after a number of scenes play or for a period of 10 minutes play.
To display an interstitial ad is quite simple. Either you choose with Google Admob or Unity Ad would be fairly easy. I will include both samples for each of the ad, so you can place them on your game app.
First thing you have to do is to Import Google Admob plugin or Unity Ads plugin. For Google Admob plugin, please download the files in here.
For Unity ads, you can download the plugin in Unity store. If the link below does not work, you can simply search Unity Ads plugin in google.
Once you have decided which plugin you want to use, and you have setup the ad in your Google Admob account or unity ad account, you can start adding Ad banner script as below. I use C# code, so you will need Visual Studio installed on your computer.
Firstly, we will need to create a static AdInitiator.cs script, which will be used to check if it is time to load the ad. In your Unity Project create a new script called AdInitiator.cs, this will be automatically opened in Visual Studio when you click the script file.
using System; using System.Collections; using System.Collections.Generic; using System.Linq; using System.Text; using UnityEngine; using UnityEngine.SceneManagement; using UnityEngine.UI; namespace Assets.Scripts { public static class AdInitiator { public static int sceneCounter = 0; public static float lastActiveAdTime = 0f; public static float showAdAfterPassTime = 600f; public static float showAdAfterPassScenes = 10; } public static void ChangeScene(string sceneName) { AdInitiator.sceneCounter += 1; SceneManager.LoadScene(sceneName); } }
As you can see we create 4 static global variables. sceneCounter variable will be used to record a number of scene play. While the lastActiveAdTime will be used when the first time the ad has been initially load. The showAdAfterPassScenes and showAdAfterPassTime are used as checking point when those two initial counters have been incremented and passed those values. If they have passed the fixed values we then show the advertisement. There is also a function called ChangeScene. This is used to add an increment of scene play when a user clicks a button to go to another scene. So just make sure when you switch a scene, you can use this function. Or if you have your own scene loader code, you can just call add an increment to AdInitiator.sceneCounter.
Let create the AdBanner.cs for Google Admob first.
using GoogleMobileAds.Api; using System.Collections; using System.Collections.Generic; using UnityEngine; public class AdBanner : MonoBehaviour { // Use this for initialization void Start () { if(AdInitiator.lastActiveAdTime <= 0f) { AdInitiator.lastActiveAdTime = Time.time; } ShowAd(); } private void ShowAd() { ); //***For Testing in the Device*** // AdRequest request = new AdRequest.Builder() //.AddTestDevice(AdRequest.TestDeviceSimulator) // Simulator. //.AddTestDevice("08fa70905f956ebb825f13aa9b652a6e") // My test device. //.Build(); // Create an empty ad request. AdRequest request = new AdRequest.Builder().Build(); // Load the interstitial with the request. interstitial.LoadAd(request); if (Utils.sceneCounter % noOfChangeScenes == 0 && Utils.sceneCounter >= noOfChangeScenes || Time.time - Utils.lastDisplayAdTime >= Utils.showAdTime) { if (interstitial.IsLoaded()) { interstitial.Show(); AdInitiator.lastActiveAdTime = 0f; AdInitiator.sceneCounter = 0; } } } }
In the start method, you can see I initiate the first lastActiveAdTime variable value if the initial value is equal or less than 0. Then in the ShowAd function, we create a check condition to see if lastActiveAdTime or number of play scenes have passed the designed check point values. And do not forget to reset back the AdInitiator variables to 0.
This is the next code for Unity ads. It will be called AdBanner.cs as well but with different code content.
using Assets.Scripts; using GoogleMobileAds.Api; using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.Advertisements; public class AdBanner : MonoBehaviour { private string androidGameID = "xxxxxxx"; // Use this for initialization void Start() { if(AdInitiator.lastActiveAdTime <= 0f) { AdInitiator.lastActiveAdTime = Time.time; } Advertisement.Initialize(androidGameID); ShowAd(); } private void ShowAd() { if (Utils.sceneCounter % noOfChangeScenes == 0 && Utils.sceneCounter >= noOfChangeScenes || Time.time - Utils.lastDisplayAdTime >= Utils.showAdTime) { Advertisement.Show(); Utils.lastActiveAdTime = 0f; AdInitiator.sceneCounter = 0; } } }
I hope the sample code above helps you.

Hi Rafael,
The easiest way to do this would be to create a python or EASI script to run CLIP. There is an option within CLIP to use a vector segment as the clipping layer and automatically save a separate output file for each shape. This option is only available in python and EASI scripting. I’ve included a python example below:
from pci.clip import clip clip(fili=r"I:\Data\Test\irvine.pix", #input file dbic=[2], #channel(s) of input file you want to clip filo=r"I:\Data\Test\clip\clip.pix", #location for output files clipmeth="LAYERVEC_FILES", #Clipping method clipfil=r"I:\Data\Test\clip\clipfile.pix", #File with vectors used for clipping cliplay=[2], #Vector layer in clipfil laybnds="SHAPES") #Boundaries used in clipping
Hope this helps,

Different variations of a language may be desirable. For example, the XHTML 1.0 Recommendation defines strict, transitional, and frameset schemas. All three of those schemas purport to define the same namespace, but they describe different languages.
And additional languages may be defined by other specifications, such as the XHTML Basic Recommendation.
Whatever the cause, over time, different versions of the language exist and designing applications to deal with this change in a predictable, useful way requires a versioning strategy.
Whether ten, a hundred, or a million resources have been deployed, if a language is changed in such a way that all those applications will determine that texts of the new language are invalid, a versioning problem with real costs has been introduced.
Ultimately, there are different kinds of languages. The versioning approaches and strategies that are appropriate for one kind of language may not be appropriate for another. Among the various kinds of languages, we find:
Just Names: some languages are just list(s) of acceptable.. Attempting to deploy a system that provides no versioning mechanism puts the burden of version "discovery" on consumers and is often components that are not recognized.
Consider a producer and a consumer exchanging messages of a particular language. Imagine that some future version of the language defines a new component. Because producers and consumers are distributed,vit may happen that an old consumer, one unprepared for a new component, encounters a message with a new component new component and so it would "see" a message that looks just like the old message it is expecting.
For the producer, the result would be that the request is fulfilled, though perhaps not quite the way it may have hoped. component is understood, then it can change the language in a way to indicate that the new behavior is not considered optional, aka backwards compatible.
Often, what is needed is some sort of middle ground solution. language should be able to produce texts in a revision supreme:
Good Practice
Be Extensible rule: Languages should be Extensible.
A language that allows additional syntax also requires a specification of what happens when the additional syntax is in a text. By the definition of Extensibility, there is a mapping from all texts with additional syntax to texts without. If the extensibility is used in a forwards-compatible way, then by definition the software consuming the extension does not know about the extension and we call such extension an unknown extension. If the software consuming the extension "knows" about the extension, then it has been revised and uses the revised language that incorporates the extension. The behavior of software when it encounters an unknown extension, that is the mapping from texts with additional syntax to texts without, should be clear.
The simplest model that enables forwards-compatible changes is to require that a language consumer must].
An extension that affects an existing component is an incompatible change because it changes the mapping of the text with the extension to one without such that a consumer that is unaware of the extension will produce Information from the text that is incompatible with the intended Information (more work...). An additional rule is required:
Good Practice
Preserve existing information Rule: An Extensible Language MUST require that any texts with extensions MUST be compatible with a text without the extensions.
There are two specific variants of the Must Accept rule that qualify what kind of handling beyond accepting is required. One model is to remove the unknown:
Good Practice
Must Accept and Remove Unknowns Rule (Must Accept variant 1): model is to preserve the unknown. This rule is:
Good Practice
Must Accept and Preserve Unknowns Rule (Must Accept variant 2): Consumers MUST accept and preserve any text portion that they do not recognize.
HTTP 1.1 [7] specifies that a transparent proxy should accept and preserve any headers it doesn't understand: "Unrecognized header fields SHOULD be ignored by the recipient and MUST be forwarded by transparent proxies.".
In tree based languages, which includes all markup languages, Container practice was described in [HTML 2.0]
This retains the element descendents in the processing model so that they can still affect interpretation of the text, such as for display purposes... accept Unknowns". being in the Must Understand strategy.. | http://www.w3.org/2001/tag/doc/versioning-compatibility-strategies-20071026.html | CC-MAIN-2015-18 | refinedweb | 765 | 52.49 |

SaaS 4.6 Enhancing Rotten Potatoes again
Introduction
The article is intended to be an accompaniment to the SaaS video lecture 4.6 titled “Enhancing Rotten Potatoes again” [1], part of the SaaS video lecture series for the Software Engineering for SaaS hosted on the Coursera learning network. [2]
The Rotten Potatoes webpage, designed in the previous lectures is enhanced for implementing a new feature to add a new movie by looking up the TMDb database rather than manually entering the movie name. The flow of this article
Note : All images used in this article have been taken from screen captures of Coursera video lectures available here. All content is owned by original authors and there is no copyright infringement intended. References have been provided in the image descriptions wherever necessary
Scope
The scope of this article is limited only to the scope covered in the video lecture. The lecture builds upon Behavior-Driven Development (BDD) basics discussed in the video lectures before it and sets the reader up for upcoming lectures concerning Test-Driven Development (TDD). Hence for the purpose of this article, it is assumed that the reader has already read the material and watched the video lectures before this one in the series. Hence the setup for Cucumber, Capybara and BDD basics are excluded from this article. The resources dealing with these can be found in the SaaS lectures 4.1 to 4.5 in the series. Similarly, the theory and implementation of TDD as well as further discussion on BDD is excluded from the scope of this article. More details on these can be found in lectures 4.7 to 5.11 of the SaaS lecture series .[3]
A Brief Recap
Behavior-Driven Development (BDD) is a specialized development process which concentrates more on the behavioral aspects of the application as against the actual implementation of the application. [4] Storyboards are used to show how UI changes based on user actions. Even if it is tedious to draw sketches and storyboards, it helps build a ‘bigger picture’ understanding of the flow of the application for the non-technical stakeholders.
Cucumber is one of the shining tools of Rails that is used for testing purposes. It acts as a halfway between the customer and the developer by converting user stories of 3x5 cards into tests. These tests act as Acceptance tests for ensuring the satisfaction of the customer. Also, the tests act as Integration tests that ensures the communication between modules is consistent and correct
The User Story
The aim of the User story described in the video is to add a new feature to the Rotten Potatoes web page, to add a new movie to the movies list on Rotten Potatoes page. But, for adding the movie to the list, it populates the data from TMDb rather than entering the information by hand. This is aimed at reducing repetitive work since the TMDb already has a good database of movies. To do so, the ability to search TMDb from Rotten Potatoes home page needs to be incorporated in the webpage. Users can then search in TMDb if the movie is present in it and then its details can be imported into Rotten Potatoes. For integrating this feature into the application, first, a Lo-Fi UI and Storyboard is designed, which is described next.
The Storyboard
The Storyboard is to be interpreted as follows When a person wants to add a new movie to the Movies list on Rotten Potatoes, he/she will enter the new movie name and click “Search”. The controller method should search the TMDb database for the given movie. If a match is found, i.e. the movie is present in the TMDb, then the “Match” page is displayed. If there is no match, otherwise “No Match” page is displayed. These two scenarios, are the Happy Path and Sad Path implementations respectively.
Happy Path, Sad Path and Bad path
Many of us are aware of the test cases being categorized as Positive or Negative test cases. Similarly, for testing using Rails Cucumber, the tests cases are being categorized as Happy, Sad of Bad[5]. A test case that results in a positive result is called a Happy Path. E.g. On entering correct username and password on login page, the application logs the user in. A test case that yields no result is called a Sad Path. E.g. Entering invalid username or password on login page, which normally returns an ‘Incorrect username or password’ message A test case to handle an exceptional condition or situation, which the system should handle elegantly and show some message to the user is a Bad Path. E.g. Uploading image size exceeds a limited amount. User can then take corrective action.
Elaboration of the User Story
Let us consider the sad non-existent movie (sad path) Given I am on the RottenPotatoes home page Then I should see "Search TMDb for a movie" When I fill in "Search Terms" with "Movie That Does Not Exist" And I press "Search TMDb" Then I should be on the RottenPotatoes home page And I should see "'Movie That Does Not Exist' was not found in TMDb."
The Test shown above has 6 steps (The logic and code for implementing this is provided in the TDD lectures in the Coursera series).
- First the test checks if the user is on the Home Page, viz. the Home page for the application exists.
- Next, it checks for presence of the link to “Search TMDb for movie”. The test essentially simulates what a normal user would do when testing the application manually.
- In the third step, the test populates the form for the Search, with a movie name that is not present in the TMDb (since this is a sad path implementation, the search should essentially fail.)
- Next, the test checks (simulates) if the link can be clicked.
- As a consequence of this, the user should navigate to the Rotten Potatoes home page.
- For a Sad path, the user is shown a message mentioning that there was no match, on the home page itself.
When we run the test, since there is already a home page, the first step of the scenario passes.
In the second step of the scenario, there is no link on the view for adding a new movie. Hence the second step fails and the following steps are skipped.
Now, we add the link for the “search_tmdb” action. For this, the HAML for Search TMDb page should contain the following:
%h1 Search TMDb for a movie = form_tag :action => 'search_tmdb' do %label{:for => 'search_terms'} Search Terms = text_field_tag 'search_terms' = submit_tag 'Search TMDb'
These are added into the end of
app/views/movies/index.html.haml
The last two lines in the above code will be expanded into the HTML code:
<label for='search_terms'>Search Terms</label> <input id="search_terms" name="search_terms"type="text" />
Now there is a page and a link in place for the test. On running the test using Cucumber again, the test fails again. This is because there is still no method defined in the controller (movies_controller.rb) for actually searching in TMDb.
However the video tutorial in this discussion considers only the sad path scenario. To test this Sad path implementation, a dummy/fake method is defined in the movies_controller.rb which fails everytime, i.e. the search for the movie in TMDb never returns a match.
So, the following code for the fake controller method is added to the movies_controller.rb:
def search_tmdb # hardwire to simulate failure flash[:warning] = "'#{params[:search_terms]}' was not found in TMDb." redirect_to movies_path end
and since a new method has been added, we need to add a route to this controller method too. The following route is added to routes.db, just before or just after
‘resources :movies’:
# Route that posts 'Search TMDb' form post '/movies/search_tmdb'
Now, on running the test again using Cucumber, every time the method is called, it returns a failure message (since it is hard-coded). This implies that the sad path implementation passed.
The actual code and logic for implementation of this action (search_tmdb) is discussed in later lectures which discuss the TDD (Test Driven Development) process
So far we have considered the Sad path scenario.
Let us consider the happy existing movie (happy path) When I fill in "Search Terms" with "Inception" And I press "Search TMDb" Then I should be on the RottenPotatoes home page And I should see "Inception" And I should see "PG-13"
For implementation of this, instead of the hard coded Controller method, an actual controller method will have to written which searches TMDb and returns the details of the movie which will then be added to the Rotten Potatoes database. (However, this implementation is out of scope for our article. Further details of this can be found in the TDD lectures of this series.)
Now, the Happy and the Sad paths have some code in common which violates the DRY principle. So, to make it DRY, Cucumber offers a solution called Background [6]. The steps which are common to both the paths are written in Background and those steps will run in the background before all the other scenarios. No matter what scenario one runs, the steps in the Background will run first, which will DRY out the code. This also helps in reducing the effort in case any steps leading up to the scenarios (setup) are to be modified. The tester will only have to change the code in one location. In this example there is only one happy path and sad path scenario i.e. only two scenarios. However, in real world examples, there would be a larger list of scenarios which could have the same ‘setup’. The advantages of the Background facility are more pronounced in this case.
Summary
In summary, this article demonstrates the BDD/Cucumber test behaviour with the help of examples. It discusses the enhancement of Rotten Potatoes webpage for implementing a new feature, which is addition of a new movie by looking up the TMDb database rather than manually entering the movie name. This includes designing a Lo-Fi UI, writing scenarios and step definitions, even writing new methods for successfully executing the test cases using Cucumber. The article also introduces and explains the concept of Background in Cucumber, which helps in DRYing out the repeated code in scenarios of the same feature. The next chapter will discuss the TDD/RSpec behaviour and the approach to make all the scenarios pass.

We have fixed this bug for the 1.5 release. I agree that it is incorrect for the doclet to skip "overrides" or "implemented" documentation just because the method being overriden or implemented is external.
xxxxx@xxxxx 2003-05-03[This bug is re-written from bug 4854934]
It appears that when method A.m overrides method in external referenced class B,
the "Overrides:" section is not generated (but should be). That is, if B is not
passed in on the command line, javadoc does not create the "Overrides:" section
for method m. If B is passed in, then it does create the "Overrides:" section.
Example: Given this source file with method read() that overrides
"public int read()" in FilterReader:
---------------- XReader.java ---------------------
public class XReader extends java.io.FilterReader {
/**
* This is a doc comment
*/
public int read() {
return 'W';
}
}
---------------------------------------------------
Generate the HTML documentation using Javadoc 1.4.2-beta:
javadoc -d html XReader.java
The generated HTML documentation for XReader.read()
is missing any "Overrides:" labels. It actually looks
like this:
-----------------------------
read
public int read()
This is a doc comment
------------------------------
It should instead look like this, with override labels:
-----------------------------
read
public int read()
This is a doc comment
Overrides:
read in class FilterReader
~~~~ ~~~~~~~~~~~~
------------------------------
Adding the -link or -linkoffline option makes no difference --
the labels and links still do not appear when trying this:
javadoc -d html -linkoffline "" . XReader.java
In this case, "read" should be a link to java/io/FilterReader.html#read()
and "FilterReader" should be a link to java/io/FilterReader.html,
identical to this J2SE class that extends FilterReader:
The presence of these labels and links should be independent
of inheriting doc comments.
FWIW, I tested for the presenece of "Specified by:" when implementing
an external referenced class (to see if it's a problem), and it works
just fine, producing "Specified by:" labels and links. Here's that source
file:
----------------- XComparable.java -----------------------
public class XComparable implements java.lang.Comparable {
public int compareTo(Object o) {
return 'W';
}
}
--------------------------------------------------------
N/A
Accepted.

There is really nothing to fix. I can reproduce this bug in the pre-toolkit standard doclet but not in the toolkit standard doclet. This code to insert the "overriden" or "implements" documentation is included in the toolkit so it will be fixed in every doclet that uses it.
I will mark this bug as fixed when we actually get to check the toolkit into the TL workspace.

Dask DataFrame groupby
• March 9, 2022
This post explains how to perform groupby aggregations with Dask DataFrames.
You’ll learn how to perform groupby operations with one and many columns. You’ll also learn how to compute aggregations like sum, mean, and count.
After you learn the basic syntax, we’ll discuss the best practices when performing groupby operations.
Sample dataset
Let’s read a sample dataset from S3 into a Dask DataFrame to perform some sample groupby computations. We will use Coiled to launch a Dask computation cluster with 5 nodes.
import coiled import dask import dask.dataframe as dd cluster = coiled.Cluster(name="demo-cluster", n_workers=5) client = dask.distributed.Client(cluster) ddf = dd.read_parquet( "s3://coiled-datasets/h2o/G1_1e7_1e2_0_0/parquet", storage_options={"anon": True, "use_ssl": True}, engine="pyarrow", )
This dataset contains 10 million rows of data and the following columns.
Let’s run some Dask groupby aggregations now that we’re familiar with the dataset.
Dask DataFrame groupby sum
Let’s groupby the values in the
id1 column and then sum the values in the
v1 column.
ddf.groupby("id1").v1.sum().compute()
You can also use an alternative syntax and get the same result.
ddf.groupby("id1").agg({"v1": "sum"}).compute()
agg takes a more complex code path in Dask, so you should generally stick with the simple syntax unless you need to perform multiple aggregations.
Dask DataFrame groupby for a single column is pretty straightforward. Let’s look at how to groupby with multiple columns.
Dask DataFrame groupby multiple columns
Here’s how to group by the
id1 and
id2 columns and then sum the values in
v1.
ddf.groupby(["id1", "id2"]).v1.sum().compute()
You can pass a list to the Dask groupby method to group by multiple columns.
Now let’s look at how to perform multiple aggregations after grouping.
Dask groupby multiple aggregations
Here’s how to group by
id3 and compute the sum of
v1 and the mean of
v3.
ddf.groupby("id3").agg({"v1": "sum", "v3": "mean"}).compute()
You can pass a dictionary to the
agg method to perform different types of aggregations.
Let’s turn our attention to how Dask implements groupby computations. Specifically, let’s look at how Dask changes the number of partitions in the DataFrame when a groupby operation is performed. This is important because you need to manually set the number of partitions properly when the aggregated DataFrame is large.
How Dask groupby impacts npartitions
Dask doesn’t know the contents of your DataFrame ahead of time. So it can’t know how many groups the groupby operation will produce. By default, it assumes you’ll have relatively few groups, so the number of rows is reduced so significantly that the result will fit comfortably in a single partition.
However, when your data has many groups, you’ll need to tell Dask to split the results into multiple partitions in order to not overwhelm one unlucky worker.
Dask DataFrame groupby will return a DataFrame with a single partition by default. Let’s look at a DataFrame, confirm it has multiple partitions, run a groupby operation, and then observe how the resulting DataFrame only has a single partition.
Read in some data to a DataFrame and compute the number of partitions.
ddf = dd.read_parquet( "s3://coiled-datasets/h2o/G1_1e7_1e2_0_0/parquet", storage_options={"anon": True, "use_ssl": True}, engine="pyarrow", ) ddf.npartitions # 8
The Parquet dataset is read into a Dask DataFrame with 8 partitions. Now let’s run a groupby operation on the DataFrame and see how many partitions are in the result.
res = ddf.groupby("id1").v1.sum() res.npartitions # 1
Dask will output groupby results to a single partition Dask DataFrame by default. A single partition DataFrame is all that’s needed in most cases. groupby operations usually reduce the number of rows in a DataFrame significantly so they can be held in a single partition DataFrame.
You can set the
split_out argument to return a DataFrame with multiple partitions if the result of the groupby operation is too large for a single partition Dask DataFrame.
res2 = ddf.groupby("id1").v1.sum(split_out=2) res2.npartitions # 2
In this example,
split_out was set to two, so the groupby operation results in a DataFrame with two partitions. The onus is on you to properly set the
split_out size when the resulting DataFrame is large.
Performance considerations
Dask DataFrames are divided into many partitions, each of which is a pandas DataFrame. Dask performs groupby operations by running groupby on each of the individual pandas DataFrames and then aggregating all the results. The Dask DataFrame parallel execution of groupby on multiple subsets of the data makes it more scalable than pandas and often quicker too.
Running a groupby on the index is not faster than other columns in the DataFrame. Performance optimizations related to groupby operations on the DataFrame’s index are in a pull request that’s in progress.
Conclusion
Dask DataFrames make it easy to run groupby operations. The syntax is intuitive and familiar for pandas users. However, unlike pandas, setting
split_out is essential if your groupby operation will produce many groups.
The parallel execution of groupby operations makes it easy to run groupby operations on large datasets. Slow pandas groupby operations can also be sped up with parallelization powered by Dask as demonstrated in the blog post on speeding up a pandas query with 6 Dask DataFrame tricks. | https://coiled.io/blog/dask-dataframe-groupby/ | CC-MAIN-2022-21 | refinedweb | 901 | 55.44 |
Last week we learned about the basics of Elm. Elm is a functional language you can use for front-end web development. Its syntax is very close to Haskell. Though as we explored, it lacks a few key language features.
This week, we're going to make a simple Todo List application to show a bit more about how Elm works. We'll see how to apply the basics we learned, and take things a bit further.
But a front-end isn't much use without a back-end! Take a look at our Haskell Web Series to learn some cool libraries for a Haskell back-end!
Todo Types
Before we get started, let's define our types. We'll have a basic
Todo type, with a string for its name. We'll also make a type for the state of our form. This includes a list of our items as well as a "Todo in Progress", containing the text in the form:
module Types exposing ( Todo(..) , TodoListState(..) , TodoListMessage(..) ) type Todo = Todo { todoName : String } type TodoListState = TodoListState { todoList : List Todo , newTodo : Maybe Todo }
We also want to define a message type. These are the messages we'll send from our
view to update our model.
type TodoListMessage = AddedTodo Todo | FinishedTodo Todo | UpdatedNewTodo (Maybe Todo)
Elm's Architecture
Now let's review how Elm's architecture works. Last week we described our program using the
sandbox function. This simple function takes three inputs. It took an initial state (we were using a basic
Int), an
update function, and a
view function. The
update function took a
Message and our existing model and returned the updated model. The
view function took our model and rendered it in HTML. The resulting type of the view was
Html Message. You should read this type as, "rendered HTML that can send messages of type
Message". The resulting type of this expression is a
Program, parameterized by our model and message type.
sandbox : { init : model , update : msg -> model -> model , view : model -> Html msg } -> Program () model msg
A
sandbox program though doesn't allow us to communicate with the outside world very much! In other words, there's no
IO, except for rendering the DOM! So there a few more advanced functions we can use to create a
Program. For a normal application, you'll want to use the
application function seen here. For the single page example we'll do this week, we can pretty much get away with
sandbox. But we'll show how to use the
element function instead to get at least some effects into our system. The
element function looks a lot like
sandbox, with a few changes:
element : { init : flags -> (model, Cmd msg) , view : model -> Html msg , update : msg -> model -> (model, Cmd msg) , subscriptions : model -> Sub msg } -> Program flags model msg
Once again, we have functions for
init,
view, and
update. But a couple signatures are a little different. Our
init function now takes program flags. We won't use these. But they allow you to embed your Elm project within a larger Javascript project. The flags are information passed from Javascript into your Elm program.
Using
init also produces both a model and a
Cmd element. This would allow us to run "commands" when initializing our application. You can think of these commands as side effects, and they can also produce our message type.
Another change we see is that the
update function can also produce commands as well as the new model. Finally, we have this last element
subscriptions. This allows us to subscribe to outside events like clock ticks and HTTP requests. We'll see more of this next week. For now, let's lay out the skeleton of our application and get all the type signatures down. (See the appendix for an imports list).
main : Program () TodoListState TodoListMessage main = Browser.element { init = todoInit , update = todoUpdate , view = todoView , subscriptions = todoSubscriptions } todoInit : () -> (TodoListState, Cmd TodoListMessage) todoUpdate : TodoListMessage -> TodoListState -> (TodoListState, Cmd TodoListMessage) todoView : TodoListState -> Html TodoListMessage todoSubscriptions : TodoListState -> Sub TodoListMessage
Initializing our program is easy enough. We'll ignore the flags and return a state that has no tasks and
Nothing for the task in progress. We'll return
Cmd.none, indicating that initializing our state has no effects. We'll also fill in
Sub.none for the subscriptions.
todoInit : () -> (TodoListState, Cmd TodoListMessage) todoInit _ = let st = TodoListState { todoList = [], newTodo = Nothing } in (st, Cmd.none) todoSubscriptions : TodoListState -> Sub TodoListMessage todoSubscriptions _ = Sub.none
Filling in the View
Now for our view, we'll take our basic model components and turn them into HTML. When we have a list of Todo elements, we'll display them in an ordered list. We'll have a list item for each of them. This item will state the name of the item and give a "Done" button. Clicking the button allows us to send a message for finishing that Todo:
todoItem : Todo -> Html TodoListMessage todoItem (Todo todo) = li [] [ text todo.todoName , button [onClick (FinishedTodo (Todo todo))] [text "Done"] ]
Now let's put together the input form for adding a Todo. First, we'll determine what value is in the input and whether to disable the done button. Then we'll define a function for turning the input string into a new
Todo item. This will send the message for changing the new Todo.
todoForm : Maybe Todo -> Html TodoListMessage todoForm maybeTodo = let (value_, isEnabled_) = case maybeTodo of Nothing -> ("", False) Just (Todo t) -> (t.todoName, True) changeTodo newString = case newString of "" -> UpdatedNewTodo Nothing s -> UpdatedNewTodo (Just (Todo { todoName = s })) in ...
Now, we'll make the HTML for the form. The input element itself will tie into our
onChange function that will update our state. The "Add" button will send the message for adding the new Todo.
todoForm : Maybe Todo -> Html TodoListMessage todoForm maybeTodo = let (value_, isEnabled_) = ... changeTodo newString = ... in div [] [ input [value value_, onInput changeTodo] [] , button [disabled (not isEnabled_), onClick (AddedTodo (Todo {todoName = value_}))] [text "Add"] ]
We can then pull together all our view code in the
view function. We have our list of Todos, and then add the form.
todoView : TodoListState -> Html TodoListMessage todoView (TodoListState { todoList, newTodo }) = div [] [ ol [] (List.map todoItem todoList) , todoForm newTodo ]
Updating the Model
The last thing we need is to write out our
update function. All this does is process a message and update the state accordingly. We need three cases:_) -> ...
And each of these cases is pretty straightforward. For adding a Todo, we'll append it at the front of our list:_) -> let st = TodoListState { todoList = newTodo_ :: todoList , newTodo = Nothing } (FinishedTodo doneTodo) -> ... (UpdatedNewTodo newTodo_) -> ...
When we've finished a Todo, we'll remove it from our list by filtering on the name being equal.) -> let st = TodoListState { todoList = List.filter (todosNotEqual doneTodo) todoList , newTodo = newTodo } in (st, Cmd.none) (UpdatedNewTodo newTodo_) -> .. todosNotEqual : Todo -> Todo -> Bool todosNotEqual (Todo t1) (Todo t2) = t1.todoName /= t2.todoName
And updating the new todo is the easiest of all! All we need to do is replace it in the state._) -> .. (TodoListState { todoList = todoList, newTodo = newTodo_ }, Cmd.none)
And with that we're done! We have a rudimentary program for our Todo list.
Conclusion
This wraps up our basic Todo application! There are still a few more things we should learn moving on from Elm. Next week, we'll see how to implement some important types of effects any site will need. We'll see an intro to Elm's effect system, and use it to send HTTP requests.
For some more ideas on building cool products in Haskell, take a look at our Production Checklist. It goes over some libraries for many topics, including databases and parsing!

ChrisL has joined #svg
06:37:05 [anthony]
DS: I basically, changed the params spec around
06:37:08 [anthony]
... a fair bit
06:37:27 [anthony]
... I took out the ref element
06:37:31 [anthony]
... and added the param elemnt
06:37:41 [shepazu]
06:37:44 [shepazu]
06:37:45 [shepazu]
06:37:56 [anthony]
... which is equivalent to the object param in HTML
06:38:19 [anthony]
... I basically the param functional notation takes the parameter name as an argument
06:38:26 [anthony]
... as opposed to the indirection I had before
06:38:34 [anthony]
... it also highlights how you can use the fall back value
06:38:45 [anthony]
... instead of having to use a separate element for that
06:39:17 [anthony]
... you use it a second value for the param property
06:39:43 [shepazu]
attribute-name="param(string) [optional-string]"
06:40:09 [anthony]
DS: Optional string would be the default value
06:40:20 [anthony]
... I also cleaned up the IDL
06:40:33 [anthony]
... for the parameters and the window parameter interfaces
06:40:49 [anthony]
... and started talking about how we might put params into CSS
06:41:07 [anthony]
... I reworked all the examples in the Primier
06:41:15 [anthony]
s/Primier/Primer/
06:41:18 [anthony]
... to use the new syntax
06:41:25 [shepazu]
06:41:34 [anthony]
... I added an example for adding parameterised use elements
06:41:44 [anthony]
... the very last example
06:42:38 [anthony]
... we've talked about how markers and use elements, it's hard to do anything useful with them
06:42:45 [anthony]
... if you want to change parameters on them
06:42:57 [anthony]
CM: One advantage of this parameterisation use here
06:43:08 [anthony]
... is it's not very heavy weight
06:43:25 [anthony]
... substituting in one value is pretty easy
06:43:38 [anthony]
DS: With different values you can get quite different results
06:44:01 [anthony]
CM: Basically when you evaluate paint server references, you evaluate the paint at that point
06:44:10 [anthony]
... rather than the definition time
06:44:15 [anthony]
DS: When you are using something
06:44:19 [anthony]
... the shadow tree is changed
06:44:29 [anthony]
... it's treated at its own document
06:45:20 [anthony]
... I don't see how you could it any other way
06:45:30 [anthony]
CM: Probably the way implementations are handling paint servers
06:45:34 [anthony]
... might have to change
06:45:56 [anthony]
... they are kind of global at the moment, well their instances are
06:46:06 [anthony]
... that scoped thing could be interesting anyway
06:46:18 [anthony]
DS: I resolved that in the my script library by cloning the element
06:46:26 [anthony]
... then changing the IDs and ID refs
06:46:45 [anthony]
... this kind of effects use
06:46:55 [ChrisL]
So, can you say <path d="param(foo) M1 2 L 3 4" /> ?
06:47:11 [anthony]
CM: It would be interesting to see what XBL does
06:47:24 [anthony]
CL: Obviously it has to solve the same problem
06:47:36 [anthony]
... Is this restricted or can you use it on any attribute?
06:47:55 [anthony]
DS: The way I saw it was that it could be used by any attribute
06:48:00 [anthony]
... yes, could be used on a path
06:48:25 [ChrisL]
suggest another example where an animation is parameterised, in that case
06:48:26 [anthony]
... the way I'd like to see it is, that for elements with attribute values that don't take lists you can use the fallback
06:48:36 [anthony]
... for the ones that do take lists you can't use the fall back
06:49:00 [anthony]
CL: I suggest in that case to provide an animation example
06:49:05 [anthony]
... if you provide it as a child
06:49:08 [anthony]
... then parameterise that
06:49:15 [anthony]
... you could have multiple ones of them
06:49:29 [anthony]
DL: You might want to use this as only part of a value
06:49:34 [shepazu]
[[
06:49:36 [shepazu]:
06:49:43 [shepazu]
]]
06:49:55 [ed]
could you do <path d="param(foo) param(bar) M1 0 ..."> ?
06:49:58 [anthony]
s/DL/DS/
06:50:06 [anthony]
DS: [reads out text]
06:50:12 [anthony]
... ED, exactly, yes
06:50:29 [anthony]
... You could pass in parameters that would be components of a path
06:50:40 [anthony]
... you could get some rather interesting effects that way
06:50:57 [anthony]
ED: My question was is it possible to have multiple levels of params?
06:51:04 [anthony]
DS: I think that might complicate things
06:51:09 [anthony]
... I can see a use for it
06:51:22 [anthony]
... Looking at the flower example
06:51:25 [anthony]
... if we had that
06:51:28 [anthony]
... and some of the values
06:51:32 [anthony]
... instead of a gradient
06:51:36 [anthony]
... they wanted a solid fill
06:51:42 [anthony]
... they could just pass in a single value
06:51:58 [anthony]
... then in the gradient I could say, in stop one use petal one
06:52:06 [anthony]
... and for stop two use petal two
06:52:13 [anthony]
... and if they don't provide one
06:52:17 [anthony]
... use the previous
06:53:16 [anthony]
CM: You're not really thinking of it as a string substitution in the list?
06:53:18 [anthony]
DS: I am
06:53:29 [anthony]
CL: That is not clear from the spec currently
06:53:33 [anthony]
DS: I think you're right
06:54:19 [anthony]
CL: Might need to define how to do the parsing
06:54:22 [anthony]
... two level parsing model
06:54:33 [anthony]
... when you construct the attribute with the param
06:54:39 [anthony]
... then parse it as per normal
06:54:42 [anthony]
... that needs to be defined
06:54:53 [anthony]
... A two stage parsing thing might be a good thing to point out
06:55:12 [anthony]
CM: Advantages I saw to using this functional syntax is
06:55:20 [anthony]
... it gels well with CSS properties
06:55:37 [ChrisL]
first stage looks for params and the second stage parses the result according to whatever the attribute value was originally defined as
06:55:41 [anthony]
... There may be more scope with conflicts with values that can be accepted at th emoment
06:55:56 [anthony]
DS: I think if we going to do something like this, now is the time to do it
06:56:12 [anthony]
CM: I can see people saying why not use the braces similar to XSLT
06:56:26 [anthony]
DS: Curly braces?
06:56:30 [anthony]
CM: Yes
06:56:42 [anthony]
DS: That would match what Adobe do FXG
06:56:52 [anthony]
... it's their universal interchange format for XML
06:56:58 [anthony]
... for all their products
06:57:10 [anthony]
... there is post about why they didn't use SVG
06:58:18 [anthony]
... I'm fine with that idea of use braces
06:58:28 [anthony]
... if we are going to more with it like Calc
06:58:33 [anthony]
... then might have problems
06:58:43 [anthony]
... not concerned about the syntax at the moment
06:58:51 [anthony]
CM: Might consider doing it that way
06:58:57 [anthony]
... if it's string substitution
06:59:27 [anthony]
... it's what level you think that it is operating on
06:59:43 [anthony]
... if you are using the CSS DOM to get the value of param
06:59:51 [anthony]
... what do you get?
07:00:04 [anthony]
CL: What you should get back is what you would've gotten back normally
07:00:15 [anthony]
... the only difference is you give it an ID to later change it
07:00:49 [anthony]
DS: Currently it's a similar model to CSS
07:01:07 [anthony]
CM: Maybe it makes sense to expose the computed things in the animated DOM
07:01:55 [anthony]
DS: Ultimately all these things should be moving to the same model
07:02:00 [anthony]
... where it makes sense
07:02:08 [anthony]
... I modified my script library
07:02:18 [anthony]
... to take into account this param use syntax
07:02:27 [anthony]
... It did increase the size of my code
07:02:36 [anthony]
... but I did have to implement a fake shadow tree
07:02:49 [anthony]
... for people that already implement a shadow tree
07:03:02 [anthony]
.. it shouldn't be too much of a burden
07:03:22 [anthony]
ED: I'm wondering if this spec here is saying we are adding a param in the SVG name space?
07:03:27 [anthony]
... I don't think that is a good idea
07:03:33 [anthony]
... because it will conflict with HTML param
07:03:44 [anthony]
... and it's similar to what we are doing with listener
07:03:55 [anthony]
... I think it would be better to say that this element is from HTML
07:03:58 [anthony]
... and is that name space
07:04:07 [anthony]
... I sent an email to SVG and to HTML
07:04:20 [anthony]
s/... I/DS: I/
07:04:33 [anthony]
DS: Us adding elements into the SVG name space would be a good thing
07:04:37 [anthony]
... from what I gathered
07:04:47 [anthony]
... I do understand the about the conflicts problem
07:05:22 [anthony]
CL: On one hand you don't want to be flipping between SVG and HTML
07:05:30 [shepazu]
s/conflicts/chameleon namespace/
07:06:11 [heycam]
A problem with requiring having <param> namespaced to be in HTML is that people will use a prefix, and that that's not going to work well with SVG parsing in text/html.
07:06:44 [anthony]
ED: But if you're parsing param elements in Text HTML
07:06:51 [anthony]
... you'd get the param element in HTML by default at the moment
07:06:59 [anthony]
CM: So something has to be changed
07:07:31 [anthony]
DS: I thought about it, if it comes down to us pleasing the HTML working group vs making things easier for authors
07:07:35 [ChrisL]
Designing XML/Web Languages: A Review of Common Mistakes
07:07:39 [anthony]
... I'd rather make things easier for authors
07:08:08 [anthony]
CL: If you look at Robin's paper he calls it out as a specific thing
07:08:18 [anthony]
... we should've brought that stuff into our own name space
07:08:24 [anthony]
... which is reasonable
07:08:38 [anthony]
DS: In support of that, if we are thinking about the open web stack
07:09:13 [anthony]
... having features in one language in another language helps people understand that feature in the other language
07:10:44 [anthony]
... There was another piece of feedback from Robin
07:10:57 [anthony]
... if you're going to import param, import object
07:11:04 [anthony]
... just use object
07:11:23 [anthony]
... and don't change the inheritance model of use
07:11:35 [anthony]
CL: I think we are already changing the inheritance model
07:12:18 [anthony]
CM: use is a pain to implement, because you copy the exact same properties of an element
07:12:25 [anthony]
DS: We could make a new element
07:12:36 [anthony]
... that isn't a pain to implement
07:12:59 [anthony]
... we could rely on the params spec to change various different things
07:13:22 [anthony]
... for now I think we should say we have a param element, anything that references can use it
07:13:44 [anthony]
... we could make a property called "parameters" that would take a name of list value pairs
07:13:59 [anthony]
... it could also be use from within CSS as well
07:14:33 [anthony]
CL: If we start saying things like you can use this with any CSS property we may run into trouble
07:14:39 [anthony]
DS: We'd have to check with them first
07:15:02 [anthony]
... this one would just be "parameters" the only thing it does is it passes in parameters
07:15:41 [anthony]
CM: How is the referencing of parameters done with that?
07:15:49 [heycam]
parameters="fill=param(whatever), ..."
07:16:04 [anthony]
DS: It would be a pass in parameters
07:16:12 [anthony]
... not a way to receive parameters
07:16:47 [shepazu]
parameters="color:red; outline:green; label:hello;"
07:17:11 [anthony]
DS: Instead of having a param element you'd have this property
07:17:40 [anthony]
CM: So what Chris said about defining how CSS properties work, this would still have that problem?
07:17:43 [anthony]
DS: Yes
07:17:56 [ChrisL]
(found robinb's paper:
)
07:18:15 [anthony]
DS: I don't think the spec is done yet
07:18:21 [anthony]
... I'll take this feedback into account
07:18:31 [anthony]
... it's a better syntax and a better mechanism
07:18:55 [anthony]
... I'd like to republish with the new syntax and examples
07:19:00 [anthony]
CL: I have no problems with that
07:19:41 [anthony]
ED: Does the spec define what happens if you change the param in another document?
07:19:47 [anthony]
... does it have the resource
07:19:53 [anthony]
... is that implementation independent
07:20:16 [anthony]
... I'm not 100% sure if you change those params if they have some effect on the plug in for example
07:20:28 [anthony]
... I think it should be defined what should happen in such cases
07:20:33 [anthony]
DS: I have defined it in the spec
07:20:40 [anthony]
ED: Ok, maybe I haven't seen it
07:20:46 [anthony]

the other bug... is that with my code, or opera?
08:15:26 [shepazu]
naw, that's not what its primary purpose is
08:15:54 [ed]
it's probably a known bug (already fixed), but I'll take a closer look when I get to work

DEVDOJO course on javaScript Basics
The trim() method is used to remove white space and from both ends of a string (white space meaning characters like space, tab, no-break space and so on). It also removes line terminator characters such as carriage return (CR) and line feed (LF).
SYNTAX:
str.trim()
where str is the string which will be returned stripped of white space from both ends.
In this instance, we shall strip the string ? java ? of its white space;
var init = ? java ?;
console.log(init.trim()); // logs ?java?
To crosscheck (It?s alright to feel something isn?t right :)):
var initShort = init.trim();
console.log(init.length()); // logs 6, one white space on each side
console.log(initShort()); // logs 4, no white space
Sometimes str.trim() may not be natively available (not implemented specifically). If that?s the case, to use str.trim(), we would have to run this little snippet of code before any other code.
if (!string.prototype.trim) {
String.prototype.trim = function() {
return this.replace(/^[suFEFFxAO] + |[suFEFFxAO] + $ /g, ? ?);
};
}
In addition to str.trim(), two ?sub-methods?, str.trimLeft() and str.trimRight() which (as you might have guessed) removes white space from the left and right ends of a string respectively. Although both are supported on Chrome, Edge and Firefox, they are recognized as non-standard and shouldn?t be used on production sites as they will not work for every user.
Browser Compatibility:
Desktop Browsers such as Chrome, Edge, Firefox(3.5 (1.9.1)), Internet Explorer 9, Opera 10.5 and Safari 5 support str.trim()
Mobile Browsers: Most browsers on mobile platforms support str.trim()
NOTE: str.trim() can only be used to remove white space before and after a string, to remove white space between the string, we would have to be a bit more creative and use str.split(? ?). join(??)
An Example: var initials = ?R C?;
var newInitials = initials.split(? ?).join(??);
console.log(newInitials); // logs ?RC? | https://911weknow.com/javascript-properties-and-methods-string-prototype-trim | CC-MAIN-2022-33 | refinedweb | 325 | 69.58 |
Data Visualization with Pandas
Data visualization is the discipline of trying to understand data by placing it in a visual context so that patterns, trends and correlations that might not otherwise be detected can be exposed.. Doing visualizations with pandas comes in handy when you want to view how your data looks like quickly.
import numpy as np import pandas as pd import seaborn as sns import matplotlib.pyplot as plt %matplotlib inline from numpy.random import randn, randint, uniform, sample.
Series is a one-dimensional labeled array capable of holding data of any type (integer, string, float, python objects, etc.). Each column of the dataframe is a Series.
Below we are creatind a dataframe
df which consists of 1000 random numbers generated by
rand().
index specifies the index to use for resulting frame.
date_range() returns a fixed frequency DatetimeIndex which start date ‘2019-06-07’.
periods is used to specify the number of periods to generate. Through
columns we can specify the column labels to use for resulting frame. Similarly, we are creating a Series
ts.
df = pd.DataFrame(randn(1000), index = pd.date_range('2019-06-07', periods = 1000), columns=['value']) ts = pd.Series(randn(1000), index = pd.date_range('2019-06-07', periods = 1000))
df.head()
ts.head()
2019-06-07 0.430385 2019-06-08 1.810955 2019-06-09 3.207345 2019-06-10 -0.366252 2019-06-11 1.406304 Freq: D, dtype: float64
type(df),type(ts)
(pandas.core.frame.DataFrame, pandas.core.series.Series)
Line plot
The
cumsum() function is used to get cumulative sum over a DataFrame or Series axis. It returns a DataFrame or Series of the same size containing the cumulative sum.
df['value'] = df['value'].cumsum() df.head()
ts = ts.cumsum() ts.head()
2019-06-07 0.430385 2019-06-08 2.671725 2019-06-09 8.120411 2019-06-10 13.202844 2019-06-11 19.691581 Freq: D, dtype: float64
type(df), type(ts)
(pandas.core.frame.DataFrame, pandas.core.series.Series)
Now we will visualize
ts.
plot() is a function which makes plots of DataFrame using matplotlib / pylab. We can specify the figure size using
figsize. We need to pass a tuple (width, height) in inches.
ts.plot(figsize=(10,5))
Now we will plot the dataframe
df.
df.plot()
load_dataset() loads an example dataset from the online repository (requires internet). Here we have loaded the
iris dataset from seaborn.
iris = sns.load_dataset('iris') iris.head()
Now we will plot the
iris dataframe. Using
title we can add a Title for the plot. We have even set the axes labels.
ax = iris.plot(figsize=(15,8), title='Iris Dataset') ax.set_xlabel('X Axis') ax.set_ylabel('Y Axis')
Now we will plot the series again but this time we will add the
style parameter.
-- means dashed line style and
r means red colour. Hence
r-- means red dashed line.
legend = True places legend on axis subplots using the name specified using
label.
ts.plot(style = 'r--', label = 'Series', legend = True)
logy = True uses log scaling on y axis.
iris.plot(legend = False, figsize = (10, 5), logy = True)
Now we will see how to plot data on the secondary axis. For that we will create 2 dataframes
x and
y as shown below. We will plot
sepal_width and
petal_width on the primary axis and
sepal_length and
petal_length on the secondary axis.
x = iris.drop(['sepal_width', 'petal_width'], axis = 1) x.head()
y = iris.drop(['sepal_length', 'petal_length'], axis = 1) y.head()
If
secondary_y = True then data is plot on a secondary y-axis. Now we will plot x on the primary axis and y on the secondary axis of the same plot.
ax = x.plot() y.plot(figsize = (16,10), secondary_y = True, ax = ax)
We can adjust the tick resolution using
x_compat.
x.plot(figsize=(10,5), x_compat = True)
Bar Plot
Now we will see how to draw bar plots. The
species column in
iris contains non-numeric values. Hence we will
drop it and save the resultant dataframe in
df.
df = iris.drop(['species'], axis = 1) df.head()
Now we will draw a bar plot for the first row of
df.
df.iloc[0].plot(kind='bar')
You can even draw the same plot using the line of code given below.
df.iloc[0].plot.bar()
Now we will load the
titanic dataset from seaborn.
titanic = sns.load_dataset('titanic') titanic.head()
To see the distribution of a single column we can plot a histogram. Here we have drawn a histogram for
pclass. The 3 bars represent the 3 different values in
pclass.
titanic['pclass'].plot(kind = 'hist')
Now we will create a dataframe df which will have 10 rows and 4 columns. It will containd= random values which will be generated by
randn(). The column names will be a, b, c and d respectively.
df = pd.DataFrame(randn(10, 4), columns=['a', 'b', 'c', 'd']) df.head()
df.plot.bar()
Stacked Plot
Now we will plot a stacked plot for
df.
stacked = True lots stacked bar charts for the DataFrame.
df.plot.bar(stacked = True)
We can even draw the same plot which the line of code givwn below.
df.plot(kind = 'bar', stacked = True)
Till now we have drawn vertical bar plots. Now we will see how to plot horizontal bar plots. A horizontal bar plot is a plot that presents quantitative data with rectangular bars with lengths proportional to the values that they represent. For this we will use the
barh() function.
plt.axis('off') turns off axis lines and labels.
df.plot.barh(stacked = True) plt.axis('off')
Histogram
A histogram is a representation of the distribution of data.
We can draw a histogram using the
hist() function.
iris.plot.hist()
Alternatively, you can even plot it in this way.
iris.plot(kind = 'hist')
A histogram displays numerical data by grouping data into “bins” of equal width. Each bin is plotted as a bar whose height corresponds to how many data points are in that bin. Bins are also sometimes called “intervals”, “classes”, or “buckets”. We can use
bins to specify the number of bins.
iris.plot(kind = 'hist', stacked = True, bins = 50)
We can draw a horizontal histogram by passing
orientation = 'horizontal'.
iris.plot(kind = 'hist', stacked = True, bins = 50, orientation = 'horizontal')
The
diff() function calculates the difference of a DataFrame element compared with another element in the DataFrame.
iris['sepal_width'].diff()[:10]
0 NaN 1 -0.5 2 0.2 3 -0.1 4 0.5 5 0.3 6 -0.5 7 0.0 8 -0.5 9 0.2 Name: sepal_width, dtype: float64
We can plot the histogram of the difference.
iris['sepal_width'].diff().plot(kind = 'hist', stacked = True, bins = 50)
We will drop the
species column as it is non-numeric and take difference of all the other columns.
df = iris.drop(['species'], axis = 1) df.diff()[:10]
Now if we plot the histogram we will get 4 separate subplots for each column in
df.
df.diff().hist(color = 'r', alpha = 0.5, figsize=(10,10))
_20<<
color = {'boxes': 'DarkGreen', 'whiskers': 'r'} color
{'boxes': 'DarkGreen', 'whiskers': 'r'}
Now we will plot a box plot for
df. We have set the colour of the boxes to
DarkGreen and colour of the whiskers to
r i.e. red.
df.plot(kind = 'box', figsize=(10,5), color = color)
We can plot a horizontal box plot by passing
vert = False.
df.plot(kind = 'box', figsize=(10,5), color = color, vert = False)
Area and Scatter Plot
An area plot displays quantitative data visually. We can pass
kind='area' to draw a area plot.
df.plot(kind = 'area')
Area plots are stacked by default. To draw unstacked area plots we have to set the parameter
stacked to
False.
df.plot.area(stacked = False)
Now we will draw scatter plots In scatter plots the coordinates of each point are defined by two dataframe columns and filled circles are used to represent each point. This kind of plot is useful to see complex correlations between two variables.
df.plot.scatter(x = 'sepal_length', y = 'petal_length')
c is a parameter which decides the color of each point. Here we have passed the column name
sepal_width whose values will be used to color the marker points according to a colormap.
df.plot.scatter(x = 'sepal_length', y = 'petal_length', c = 'sepal_width')
We can group 2 scatter plots in the same figure as shown below. Here we have drawn a plot for
sepal_length vs
petal_length and
sepal_width vs
petal_width in the same axes.
ax = df.plot.scatter(x = 'sepal_length', y = 'petal_length', label = 'Length'); df.plot.scatter(x = 'sepal_width', y = 'petal_width', label = 'Width', ax = ax, color = 'r')
s is used to control the size of each point. Here the size will value according to the values in
petal_width.
df.plot.scatter(x = 'sepal_length', y = 'petal_length', c = 'sepal_width', s = df['petal_width']*200)
Hex and Pie Plot
A Hexbin plot is useful to represent the relationship of 2 numerical variables when you have a lot of data point. Instead of overlapping, the plotting window is split in several hexbins, and the number of points per hexbin is counted. The color denotes this number of points.
Now we will draw a hexbin plot.
gridsize is used to specify the number of hexagons in the x-direction. The corresponding number of hexagons in the y-direction is chosen in a way that the hexagons are approximately regular. Alternatively, gridsize can be a tuple with two elements specifying the number of hexagons in the x-direction and the y-direction.
C specifies values at given coordinates.
df.plot.hexbin(x = 'sepal_length', y = 'petal_length', gridsize = 10, C = 'sepal_width')
Now we will move on to pie plots. A pie plot is a proportional representation of the numerical data in a column. To start with we will only consider the first row.
d = df.iloc[0] d
sepal_length 5.1 sepal_width 3.5 petal_length 1.4 petal_width 0.2 Name: 0, dtype: float64
d.plot.pie(figsize = (10,10))
Now we will see how to plot a separate pie plot for each column. For that we will take the transpose of the first 3 rows of
df.
d = df.head(3).T d
subplots = True plots separate pie plots for each numerical column independently.
d.plot.pie(subplots = True, figsize = (20, 20))
You can even change the font size.
autopct enables you to display the percent value using Python string formatting.
d.plot.pie(subplots = True, figsize = (20, 20), fontsize = 16, autopct = '%.2f')
Consider we want to).
x=[0.2]*4 print(x) print(sum(x))
[0.2, 0.2, 0.2, 0.2] 0.8
Hence we can see that we have got an incomplete pie plot as sum(x) is 0.8 which is less than 1.
series = pd.Series(x, index = ['a','b','c', 'd'], name = 'Pie Plot') series.plot.pie()
Scatter Matrix
A scatter matrix (pairs plot) compactly plots all the numeric variables we have in a dataset against each other one. First we will import
scatter_matrix.
from pandas.plotting import scatter_matrix
Now we will plot a scatter matrix for
df with the diagonal plots as Kernel Density Estimation (KDE) plots.
scatter_matrix(df, figsize= (8,8), diagonal='kde', color = 'r') plt.show()
KDE Plots
Now we will plot a KDE plot. KDE Plot described as Kernel Density Estimate is used for visualizing the Probability Density of a continuous variable. It depicts the probability density at different values in a continuous variable.
ts.plot.kde()
Andrew curves
Andrews curves have the functional form:
f(t) = x_1/sqrt(2) + x_2 sin(t) + x_3 cos(t) + x_4 sin(2t) + x_5 cos(2t) + …
Where x coefficients correspond to the values of each dimension and t is linearly spaced between -pi and +pi. Each row of frame then corresponds to a single curve.
We will import
andrews_curves.
from pandas.plotting import andrews_curves
Now we will plot andrews curves for
sepal_width.
andrews_curves(df, 'sepal_width')
Subplots
Lastly, we will see how to divide dataset into multiple separate plots. This can be done by passing
subplots = True.
sharex = False gives a separate x axis to all the plots.
df.plot(subplots = True, sharex = False) plt.tight_layout()
We can even change the layout of the subplots by using the parameter
layout.
df.plot(subplots = True, sharex = False, layout = (2,2), figsize = (16,8)) plt.tight_layout()
Data visualization provides us with a quick, clear understanding of the information. Due to graphical representations, we can visualize large volumes of data in an understandable and coherent way, which in turn helps us comprehend the information and draw conclusions and insights. Relevant data visualization is essential for pinpointing the right direction to take for selecting and tuning a machine learning model. It both shortens the machine learning process and provides more accuracy for its outcome. | https://kgptalkie.com/data-visualization-with-pandas/ | CC-MAIN-2021-17 | refinedweb | 2,131 | 68.77 |
This is one of the 100 recipes of the IPython Cookbook, the definitive guide to high-performance scientific computing and data science in Python.
We will generate one-dimensional data with a simple model (including some noise), and we will try to fit a function to this data. With this function, we can predict values on new data points. This is a curve-fitting regression problem.

lrp = lm.LinearRegression() plt.figure(figsize=(6,3)); plt.plot(x_tr, y_tr, '--k'); for deg, s in zip([2, 5], ['-', '.']): lrp.fit(np.vander(x, deg + 1), y); y_lrp = lrp.predict(np.vander(x_tr, deg + 1)) plt.plot(x_tr, y_lrp, s, label='degree ' + str(deg)); plt.legend(loc=2); plt.xlim(0, 1.4); plt.ylim(-10, 40); # Print the model's coefficients. print(' '.join(['%.2f' % c for c in lrp.coef_])) plt.plot(x, y, 'ok', ms=10); plt.title("Linear regression");
We have fitted two polynomial models of degree 2 and 5. The degree 2 polynomial fits the data points less precisely than the degree 5 polynomial. However, it seems more robust: the degree 5 polynomial seems really bad at predicting values outside the data points (look for example at the portion $x \geq 1$). This is what we call overfitting: by using a model too complex, we obtain a better fit on the trained dataset, but a less robust model outside this set.
The ridge regression model has a meta-parameter which represents the weight of the regularization term. We could try different values with trials and errors, using the
Ridge class. However, scikit-learn includes another model called
RidgeCV which includes a parameter search with cross-validation. In practice, it means that you don't have to tweak this parameter by hand: scikit-learn does it for you. Since the models of scikit-learn always follow the
fit-
predict API, all we have to do is replace
lm.LinearRegression by
lm.RidgeCV in the code above. We will give more details in the next section.
ridge = lm.RidgeCV() plt.figure(figsize=(6,3)); plt.plot(x_tr, y_tr, '--k'); for deg, s in zip([2, 5], ['-', '.']): ridge.fit(np.vander(x, deg + 1), y); y_ridge = ridge.predict(np.vander(x_tr, deg + 1)) plt.plot(x_tr, y_ridge, s, label='degree ' + str(deg)); plt.legend(loc=2); plt.xlim(0, 1.5); plt.ylim(-5, 80); # Print the model's coefficients. print(' '.join(['%.2f' % c for c in ridge.coef_])) plt.plot(x, y, 'ok', ms=10); plt.title("Ridge regression");
This time, the degree 5 polynomial seems better than the simpler degree 2 polynomial (which now causes underfitting). The ridge regression reduces the overfitting issue here.
You'll find all the explanations, figures, references, and much more in the book (to be released later this summer).

Okay ... so does that mean we can remove it?
It used to be used in prepareUserAccount before 1.2.x/1.3.x _users db security changes.
I just did a cursory review of where we use SHA1 in Futon and was under whelmed. As far as I can tell it's really only used in the tests even though it's included in every Futon page (creating a different issue for this).
If someone cares enough about Futon tests' run time then we could replace the SHA1 implementation, but it doesn't seem like a worthwhile cause to me.
Cheers.
patch doesn't apply cleanly (might be because I did the json2.js update beforehand direct from json.org)
Can you repost the patch against latest trunk, or a link to your git repo so I can clone directly?
Thanks!

we'd still need it to verify that "old" user docs still work, and it might be required in the ouath tests. that means we could remove it from futon and just have it in the test suite. | https://issues.apache.org/jira/browse/COUCHDB-833?focusedCommentId=13213777&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel | CC-MAIN-2015-27 | refinedweb | 229 | 73.68 |
.6: Driving Practice
About This Page
Questions Answered: Will I soon be able to write a Scala class fluently?
Topics: A synthesis of topics from earlier chapters. Additionally:
Shorthand operations on
vars. A few words on overloading method
names.
What Will I Do? Program and play with the resulting map-based car simulator.
Rough Estimate of Workload:? Three hours? Four? The main assignment involves some relatively independent programming work, and there’s a chance you get stuck. We recommend that you reserve a good chunk of time, carefully read the tips you’re given, and make use of O1’s forums so that it won’t take excessively long. If you don’t get stuck, you might be done in much less time.
Points Available: A5 + B80.
Related Projects: CarSim (new).
Nice to Know: Shorthand Operators for Variables
When you assign a new value to, say, a gatherer or a stepper, you use the variable’s old value as part of the expression that determines the new value. When the variable’s type is numeric, the expression is often arithmetic. Here are a couple of examples:
this.balance = this.balance + amount
this.value = this.value + 1
Since such commands are common and since they contain the same code fragment twice, the designers of Scala (and other languages) have chosen to provide a way to express the same thing more succinctly. For instance, we can alternatively write the above as:
this.balance += amount
this.value += 1
The
+= operator means: “Increase the value of the variable on the left by the value on
the right.” Or to be somewhat more precise: “Take the old value of the
var variable on the
left and the value of the expression on the right. Sum them and assign the result to the
variable on the left.”
(By the way, as you see, the notation
+= looks like the one you learned in Chapter 1.5
for adding a value to a buffer. This notation is used here for a different purpose: the
addition of numbers. Of course, there is an analogy between the two uses: a buffer is
updated by adding to it and a variable is updated by adding to it.)
Syntactic sugar
It’s common for programming languages to let us express the same meaning in different ways. Programmers often speak of syntactic sugar (syntaktinen sokeri), which refers to language constructs that aren’t necessary in terms of the language’s expressive power (i.e., they don’t enable new kinds of programs) but that make it more convenient or elegant to express certain things. The shorthand for variable assignment is an example of syntactic sugar.
Syntactic sugar is a matter of taste that programmers often quibble over. Since all general-purpose programming languages (such as Scala) are equal in terms of the computations they can express, one might even say that, in a sense, programming languages in general are merely syntactic sugar.
More shortcuts
There are more similar shorthand operators; see the table below for examples. The Scala toolkit automatically “expands” the abbreviations.
These operators are in common use and we’ll also be using them in O1. You may choose to apply them in the upcoming programming assignments, or not, as you prefer. In any case, you’ll need to be able to read code that uses the operators.
A Frequently Asked Question
In some widely used programming languages (such as C and Java),
there is a still shorter way to express the adjustment of a
variable’s value by one. For example,
number++ and
number--
mean the same as
number += 1 and
number -= 1. Do we have these
operators in Scala, too?
Answer: No. Scala’s designers haven’t seen that bit of additional
brevity as worth pursuing. One of the contributing factors is that
although there are many ways to program in Scala, one of the most
common (functional programming; Chapter 10.2) makes limited use of
vars . On the other hand, Scala is a flexible language, and you
can extend it with “operators” of your own (Chapter 4.5).
CarSim
In the CarSim application, the user can direct the movements of cars on a world map. Each car is illustrated as a colored circle.
Task description
Fetch CarSim. It contains a good part of an application program. The GUI is ready for use. However, a key component is missing. Your task is:
- to study the documentation of
o1.carsim.Carthoroughly;
- to write the Scala program code that implements the class, building on the given skeleton code; and
- to test that your class works as specified in the Scaladocs, fixing any bugs that remain.
???
In several places within the skeleton code, there are three question
marks:
???. This is a Scala expression for a part of a program
that is as yet unimplemented. Attempting to evaluate such an
expression yields a runtime error. (This will happen, for instance,
if you try calling one of the methods in the given
Car class.)
We recommend that you tackle the assignment in stages, as described below.
Step 1 of 6: Instance variables
You need to figure out which instance variables you need so that you can keep track of car’s state between method calls. Some of the variables should be private so that users of the class can’t arbitrarily modify their values.
The Scaladocs spell out the constructor parameters, as does the given code. In the code,
some of the parameters have also been (correctly) associated with a corresponding instance
variable. What are the other key attributes of a
Car; that is, what other info does a
Car
object need to track in order for its methods to work? What kind of variables would
help you store that information? What are the types and roles of each variable?
It’s not necessary to come up with every last variable right away. You can return to this step later if the need arises.
Stick to the specified interface, please
Do not add public members to the class beyond those requested. On the other hand, you’re free to add private members as you see fit.
This guideline applies to all of O1’s programming assignments that specify the public interfaces of the classes that you implement.
Step 2 of 6: The easier(?) methods
Ignore the most complex method,
drive, for now. Implement the other methods first.
Two methods named
fuel?
Did you notice that there are two different methods named
fuel,
with different parameter lists?
Even though these are two entirely separate methods, you can use
one of them to implement the other: the parameterless
fuel is
easy to implement simply by calling the other
fuel and passing
a large enough number as a parameter.
Further down in this chapter, there is some additional information about methods that share a name.
Step 3 of 6: Test your class as a separate component
Try running the test program
CarTest that uses
Car separately from the entire CarSim
app. Apart from driving, the test program should now produce output that makes sense.
You can edit the test program to improve coverage. You can also experiment with
Car
in the REPL.
Step 4 of 6: Test your class as part of CarSim
Launch CarSim via the app object
o1.carsim.gui.CarSim. Try adding cars and fueling them
through the GUI. There are some usage instructions at the bottom of the GUI window.
Step 5 of 6: Implement
drive
As the documentation says: in this assignment, you can assume that each car moves in a straight line, “as the crow flies”. Sometimes, a car will fail to reach the destination as its fuel runs out.
In case you have trouble with the math required to determine where a car stops, this may help:
- Despite the fact that CarSim uses the
xand
yof a
Posto represent latitude and longitude on the Earth’s round surface, this assignment has been set up for you so that you can continue to think about
Posobjects in terms of ordinary, flat, two-dimensional coordinates.
- Forget programming for a while, draw a diagram of the car’s movement, and solve the mathematical problem first. Only then should you consider how you can express the solution as Scala.
- You won’t need any trigonometry. Basic arithmetic (multiplication, addition, division, and subtraction) will do. In addition, you can draw on the methods of class
Pos: the already-familiar
distancemethod will be of use, and you may find other methods described in the docs helpful as well.
- You don’t have to model the car’s velocity. Just take care of the things described in the Scaladocs.
Step 6 of 6: More testing
Test
drive. Again, you may wish to test the method first in the separate test program,
then as part of the full app.
Play with CarSim.
How do the cars drive about?
You may be wondering how the cars of CarSim twine their way on the map even though your own implementation was so straightforward.
The CarSim application does use your code but it’s clever about how
it does that: it represents the complex route between the starting
location and the destination as tiny straight segments and calls your
drive method for each segment in quick succession. If you want, you
can use CarSim’s Settings menu to display the segments.
And what about finding the correct route? The application does that with the help of an an online service by Here.com, which resembles the perhaps more familiar location services provided by Google. The map images also come from an online service.
If you want, you can take a look at other CarSim components, which accomplish the above. However, be warned that if you’re a beginner programmer, the code doesn’t make for easy reading. In any case, you can take from this assignment the lesson that programs can be built upon powerful external services.
Submission form
A+ presents the exercise submission form here.
On Method Overloading
Overloading and return types in Scala
Chapter 1.8 brought up the fact that you can annotate any Scala function with its return type. In some contexts, these annotations are mandatory. Perhaps the most common example of such a context is an overloaded method that calls another method of the same name. We must assist Scala’s automatic type inference by explicitly defining the type of the method that calls its namesake. You can confirm this for yourself as follows.
Did you implement the parameterless
fuel method by calling the single-parameter
fuel,
as suggested? If you did, now try removing the type annotation (the colon and the word
Double) in the method header. You’ll be presented with the error “overloaded method
fuel needs result type”.
The phenomenon is easy to observe in the REPL, too:
class MyClass { def method(first: Int, second: Int) = first + second def method(number: Int) = this.method(number, number) }<console>:13: error: overloaded method method needs result type def method(number: Int) = this.method(number, number) ^ class MyClass { def method(first: Int, second: Int) = first + second def method(number: Int): Int = this.method(number, number) }defined class MyClass
This business with the return type is just a little quirk of Scala’s; it has no broader significance to us. Fortunately, if you forget about it, you get a clear error message. Also remember that annotating a method with a return type is always a valid choice.
Additional Material: On Accessor Methods
Trouble with naming: instance variable vs. method
Here are a few familiar example programs that all have a “look-but-don’t-touch” aspect:
- In the
Orderclass of Chapter 3.1, we wanted an order’s total price to be available to the class’s user (via the method
totalPrice). However, we did not wish for the user to directly modify that information (by assigning to variable
sumOfPrices). So we used a private
varvariable and had the public method return its value.
- We applied the same idea to FlappyBug, where the movements of the bug and the obstacle are restricted by their respective classes and recorded internally in their
currentPosvariables. The classes’ user has access to their public
posmethods.
- In Chapter 3.4, the number of goals scored by each team was recorded in private variables (
awayCount,
homeCount). Class
Match’s interface provided access to these values through two corresponding methods (
awayGoals,
homeGoals).
- Perhaps you also did something similar in the CarSim assignment above?
All the above classes have some data that is stored internally in a variable but accessed by the user via a method. The creator of the classes needs to pick two names: one for the variable, one for the method. Each is related to the same domain entity.
There is no single best solution. Different programmers adopt different solutions in different cases.
If you can’t come up with two good names, use the better name for the public method and the worse name for the private variable. By doing this, you prioritize the ease of use of the class.
Some programmers like to use abbreviations in the names of private instance variables. If you do, make sure you still keep your code readable.
Some programmers like to mark the private variables with a prefix
such as
mBuyer (where
m = member of the class) or
_buyer.
Some other programming languages promote the following style:
buyer (variable) vs.
getBuyer (method). This convention doesn’t
put usability first, however. In Scala, it’s seldom used.
In most of O1’s programming assignments, the public names have been specified for you in advance and you’re free to come up with the private names.
By the way: notice how this naming headache arises only when we use
vars. When it comes to
vals, things are simpler, because you
can’t assign a new value to a
val and there’s no need for a separate
method.
Occasionally asked question: Don’t we use “getters” and “setters” in Scala, like we do in Java?
In the examples listed above, we associated a
var with a so-called
“getter” method that returns the
var’s value. However, we haven’t
defined such a “getter” for nearly all of the instance variables in
our programs.
In Scala programs, it’s common to leave instance variables public when they represent externally visible attributes of objects. “Getters” are more the exception than the rule.
Consider this example:
class Profile(val name: String, var status: String) { // methods go here }
The variables that record the profile’s name and status are public. Their values can be examined by any programmer who uses the class; that user can also assign a new value to the latter variable. Had we written this class in “Java style”, it would look like this:
class Profile(private val name: String, private var status: String) { def getName = this.name def getStatus = this.status def setStatus(status: String) = { this.status = status } // additional methods go here }
“Getters” and “setters” like this are ubiquitous in Java programs (and in various other languages what support object-orientation). There are countless style guides that tell the beginner Java programmer to avoid public instance variables like the plague. An earlier Java-based incarnation of O1 also commanded students thus:
Why? And why doesn’t that commandment apply to Scala, so that we can write public variables with impunity? Does Scala in fact actually have implicit “getters” of a sort behind the curtain, even though we don’t explicitly define them?
If you’re interested, you can read up on these questions online. Here are a couple of links to get you started.
- Reasoning behind the Java convention: Why use getters and setters?
- Reasoning behind the Scala convention: Getters and Setters in Scala
Additional Material: Constructors and Parameters
Overloading constructors
We just discussed overloading methods. You can also overload a constructor; that is, you can define multiple ways of instantiating a class from different parameters. You won’t need to in O1, though.
Let’s write a small class as an experiment. First of all, we should be able to instantiate the class so that we pass in a word and a number as constructor parameters:
new Experiment("cat", 100)res0: Experiment = an object whose word is cat and whose number is 100
Nothing new so far. This class matches the requirement:
class Experiment(val word: String, val number: Int) { override def toString = "an object whose word is " + this.word + " and whose number is " + this.number }
But what if we also wish to be able to instantiate the class so that we pass in just a number, in which case the class will use the default word “llama”?
new Experiment(10)res1: Experiment = an object whose word is llama and whose number is 10
Moreover, we’d like to be able to just pass in a word and use a default number of 12345:
new Experiment("dog")res2: Experiment = an object whose word is dog and whose number is 12345
We can enable these alternative means of instantiation by overloading the class’s constructor. Scala has a particular notation for this:
class Experiment(val word: String, val number: Int) { def this(word: String) = this(word, 12345) def this(number: Int) = this("llama", number) override def toString = "an object whose word is " + this.word + " and whose number is " + this.number }
def thisdenotes the start of an alternative constructor. The round brackets that follow list the parameters that are required for that instantiation method.
this(...
)means, roughly: “Create an instance in the normal fashion, passing in the bracketed information as constructor parameters.” For example, here we say that if just a word has been supplied, we create the instance using that word and the number 12345.
If flexible instantiation is the goal, constructor overloading is not the only solution, or necessarily the most convenient one: see the next box.
Default parameter values
Either
new Experiment2("llama", 453534) or simply
new Experiment2("llama")
will instantiate this class:
class Experiment2(val word: String, val number: Int = 12345) { override def toString = "an object whose word is " + this.word + " and whose number is " + this.number }
You can set a default value on a method parameter just as you can on a constructor parameter.
Named parameters
Default parameter values are sometimes convenient but you won’t need to write methods that have them in O1.
Also in the same category are named parameter values, commonly known as named arguments.
Challenging reads
If you have prior programming experience, you may wish to do a web search for builder pattern. You should be able to find some more challenging material on constructor parameters.
The article Type-Safe Builder Pattern in Scala. is an interesting read but unsuitable for beginners.
Summary of Key Points
- Some applications use interfaces (APIs) created by external providers. Some such interfaces are available as services on the internet.
- For example, the application in this chapter used an online mapping service.
- You’ll learn more about accessing network services in O1’s follow-on courses.
- There are shorthand notations (e.g.,
+=,
*=) for some common commands that manipulate
varvariables.
- You can overload a method name: a class can have multiple distinct methods with the same name but different parameter lists and different implementations.
- In Scala, if you call an overloaded method from one of its namesake methods, you must explicitly mark the calling method’s return type.
- Links to the glossary: API; to overload, signature; syntactic sugar..

’ll need the following:
- A free Twilio Account. If you use this link to register, you will receive $10 credit when you upgrade to a paid account.
- Python 3.6 or newer
- Ngrok. This will make the development version of our application accessible over the Internet.
- A smartphone with an active number and WhatsApp installed.
Creating a Python environment
Let’s create a directory where our project will reside. From the terminal, run the following command:
$ mkdir twilio_whatsapp_bot: A Twilio helper library that will make it easy for us to create valid TwiML.
- Requests: A Python library for making HTTP requests.
To install all the dependencies at once, run the following command:
$ pip install flask twilio requests
Creating the Bot
Before we get started with building the bot, let’s quickly go through how the bot will work. In order for the bot to work as expected, messages that require conversion need to be in a particular format. So for example, a user needs to send a message in the format “Convert 5 BTC to USD”, where 5 is the number of BTC units to convert and USD is the currency code of the currency you would like to get the equivalent number of BTC units in.
The Twilio API for WhatsApp makes use of webhooks to notify our application whenever our bot receives a message. Let’s create a simple function that will respond to this webhook.
At the root of your project’s directory, create a
main.py and add the following code to the file:
from flask import Flask, request from twilio.twiml.messaging_response import MessagingResponse import requests app= Flask(__name__) @app.route('/incoming/twilio', methods=['POST']) def incoming_twilio(): incoming_message=request.form['Body'].lower() message= incoming_message.split() resp= MessagingResponse() msg=resp.message() if 'hello' in incoming_message: reply = standard_response_format() msg.body(reply) return str(resp) if len(message) < 4: reply = standard_response_format() msg.body(reply) return str(resp) btc_unit = message[1] currency_code = message[4].upper() r = requests.get("") if r.status_code == 200: rates = r.json()['data']['rates'] if currency_code in rates: unit_rate = rates[currency_code] unit_conversion = get_unit_conversion(btc_unit, unit_rate) reply=f"{btc_unit} BTC is {unit_conversion:,} {currency_code}" else: reply=f"{currency_code} is not a valid currency code" else: reply= "Something went wrong" msg.body(reply) return str(resp) def standard_response_format(): return ("Welcome to the Bitcoin Currency Converter bot!\n\n" "Please use the following format to chat with the bot: \n" "Convert 1 BTC to USD \n" "1 is the number of BTC unit you would like to convert \n" "USD is the currency code you would like to convert too \n") def get_unit_conversion(unit, unit_rate): return round(round(float(unit_rate), 2) * float(unit), 2) if __name__ == '__main__': app.run()
Let’s go over what’s happening in the
incoming_twilio() function.
The first thing we did was to obtain the content of the message that was sent using Flask’s
request object. This comes in the payload of the
POST request with a key of
Body. Since we’ll be doing some basic analysis on the message, the message is converted to lowercase to avoid any issue that might arise as a result of case variations.
Next, the message itself is converted into a
list using the
split() method. Based on the agreed messaging format, the default separator in this case will be any whitespace.
A further analysis is carried out to check if the keyword
hello is contained in the message. If
hello is found in the message, a generic response is sent to the back to the user informing them of how to make use of the bot.
Similarly, another check is carried out to ensure that after the message has been converted into a list, the number of items contained in the list is not less than 4. Again, this is due to the agreed messaging format with the bot.
The number of BTC units to convert and the currency code are contained at indexes 1 and 4 of the list` respectively. Next, a HTTP GET request is made to the Coinbase API to obtain the current exchange rates with BTC as the base currency. The returned rates will define the exchange rate for one unit of BTC. Here’s an example of the response received from the API.
{ "data": { "currency": "BTC", "rates": { "AED": "36.73", "AFN": "589.50", "ALL": "1258.82", "AMD": "4769.49", "ANG": "17.88", "AOA": "1102.76", "ARS": "90.37", "AUD": "12.93", "AWG": "17.93", "AZN": "10.48", "BAM": "17.38", ... } } }
Once the response from the API has been obtained, a check is carried out to ensure that the currency code obtained from the
list earlier can be found as a key under the
rates payload. If it exists, the
get_unit_conversion() function, which does the actual conversion, is then called passing in the unit rate of the identified currency code as well as the number of BTC units to convert.
Once we’ve applied our logic to determine the bot’s response based on the
body of the message received, we need to send back a reply. Twilio expects this reply to be in Twilio Markup Language (TwiML). This is an XML-based language but we’re not required to create XML directly. The
MessagingResponse class from the Twilio Python helper library helps us to send the response in the right format.
Setting up Ngrok
Since our application is currently local, there’s no way for Twilio to be able to send POST requests to the endpoint we just created. We can use Ngrok to set up a temporary public URL so that our app is accessible over the web.
To start the application, run the following command from the terminal:
$ python main.py
With the application running,.
Configure Twilio WhatsApp Sandbox
Before you’re able to send and receive messages using the Twilio API for WhatsApp in production, you’ll need to enable your Twilio number for WhatsApp. Since “Programmable SMS / WhatsApp Beta” and paste the Ngrok URL we noted earlier on the “WHEN A MESSAGE COMES IN” field. Don’t forget to append
/incoming/twilio at the end of the URL so that it points at our Flask endpoint. Click “Save” at the bottom of the page.
Testing
You can try testing the functionality of the bot by sending messages to it from your smartphone using WhatsApp. Here’s an example of me chatting with the bot:
Conclusion
In this tutorial, we have created a simple WhatsApp chatbot that returns the Bitcoin equivalent price in any supported currency. This was implemented using Flask and the Twilio API for WhatsApp. The Bitcoin exchange rate was obtained from the Coinbase API. The GitHub repository with the complete code for this project can be found here.

Meet Rich Burroughs
by Rich Burroughs
Hi, I’m Rich Burroughs, and I’ve just joined Loft Labs as a Senior Developer Advocate. I’m very excited to be here, and I’d like to share a bit about why I joined the team.
Multitenancy in Kubernetes is a nightmare. Everyone knows it. Namespaces are great but they don’t provide the isolation that a lot of teams need. A developer who has access to a namespace can’t manage things like CRDs, which live outside the namespace, or see cluster-wide resources.
What this leads to is one of two results, which are both pretty painful. Either you use shared clusters and your developers have to live with those problems, or you create dedicated clusters for teams. If you go that second route, you probably have multiple clusters per team for different environments. That seems to be the path that most teams are taking.
How do you keep up with all of those clusters, let alone manage them? Cluster sprawl is a huge problem, and as Holly Cummins mentioned in her fantastic KubeCon 2020 EU keynote, the problem isn’t just financial. There’s an impact on the environment as well.
Loft’s Spaces are a level of abstraction above namespaces that let users access a space as if it was their own dedicated cluster. Spaces are powered by Virtual Clusters, which I think are a huge advancement in how we manage clusters. You can even have idle clusters sleep to save on resources.
If multitenancy was the only problem the Loft Labs team had tackled, I’d be pretty impressed. But there’s a lot more. With Loft, users can provision their own spaces when they need them. If you’ve ever opened a ticket to get someone else to provision an environment for you, you know how vital self-service is. It helps keep cycle times lower and developer happiness higher.
And speaking of cycle times, the Loft team has also built DevSpace, a developer workflow tool for engineers working with Kubernetes clusters. Have you ever waited around for a new container to build so you can see if your changes work? Or even worse, for a CI pipeline to run integration tests? With DevSpace you can hot reload your app in the running container as you make changes. It’s super cool and it’s open source. You don’t have to be a Loft customer to use DevSpace.
Honestly, I’m blown away by how much the Loft Labs team has built with just a few engineers. What impresses me more is that the tools they’ve built help solve the very real-world pain that engineers and platform teams feel. That’s really the thing that made me want to join the team. When I saw what they were building, I knew the vision behind it was very on point.
And last but not least, I’m delighted to be working in the Kubernetes community. I first saw Kelsey Hightower speak about Kubernetes in 2015, when he was still working at CoreOS, and I was hooked. Since then, I’ve met a lot of amazing people in the Kubernetes community. I wanted an excuse to talk to them more, so in 2020 I created the Kube Cuddle podcast to interview people about their experiences with Kubernetes. You can find it in your podcast player by searching for the name or listen to episodes here.
I’m excited to talk to you all about what we’re doing at Loft. If you’d like to say hi, you can find me on Twitter, in the Loft Slack, or the #devspace channel in the Kubernetes Slack. Let me know if you have any questions about Loft or DevSpace.

Introduction
Merging PDF files is often a required operation after scanning multiple pages of documents, or saving multiple pages as individual documents on your computer.
There are several software such as Adobe as well as online tools that can help perform this task quickly. However most of them are either paid or might not have enough security features provided.
In this tutorial we will explore how to merge PDF files using Python on your computer with a few lines of code.
To continue following this tutorial we will need the following two Python library: PyPDF2.
If you don’t have them installed, please open “Command Prompt” (on Windows) and install them using the following code:
pip install PyPDF2
In order to continue in this tutorial we will some PDF files to work with.
Here are the three PDF files we will use in this tutorial:
These PDF files will reside in the pdf_files folder, which is in the same directory as the main.py with our code.
Here is how the structure of my files looks like:
Merge two PDF files using Python
In order to perform PDF merging in Python we will need to import the PdfFileMerger() class from the PyPDF2 library, and create an instance of this class.
In this example we will merge two files: sample_page1.pdf and sample_page2.pdf.
In this case, the two file names can be placed into a list, which we will then iterate over and append one to another:
from PyPDF2 import PdfFileMerger #Create and instance of PdfFileMerger() class merger = PdfFileMerger() #Create a list with file names pdf_files = ['pdf_files/sample_page1.pdf', 'pdf_files/sample_page2.pdf'] #Iterate over the list of file names for pdf_file in pdf_files: #Append PDF files merger.append(pdf_file) #Write out the merged PDF merger.write("merged_2_pages.pdf") merger.close()
And you should see merged_2_pages.pdf created in the same directory as the main.py file with the code:
Merge many PDF files using Python
In this section we will explore how to merge many PDF files using Python.
One way of merging many PDF files would be to add the file names of every PDF files to a list manually and then perform the same operation as in the previous section.
But what if we have 100 PDF files in the folder? Using the os library we can access all of the file names in a given directory as a list and iterate over it:
from PyPDF2 import PdfFileMerger import os #Create and instance of PdfFileMerger() class merger = PdfFileMerger() #Create a list with PDF file names path_to_files = r'pdf_files/' #Get the file names in the directory for root, dirs, file_names in os.walk(path_to_files): #Iterate over the list of file names for file_name in file_names: #Append PDF files merger.append(path_to_files + file_name) #Write out the merged PDF merger.write("merged_all_pages.pdf") merger.close()
And you should see merged_all_pages.pdf created in the same directory as the main.py file with the code:
Conclusion
In this article we explored how to merge multiple PDF files using Python.

About this series
This series explores application architectures that use a Service Oriented Architecture (SOA) on the back end implemented with the Grails framework. Explore how much Grails simplifies creating Web applications in general and Web services in particular. This kind of back end can be easily hooked up to any pure client-side application. In Part 1, you will use Adobe Flex to create such an application that leverages the Flash Player. In Part 2, you will use the Google Web Toolkit to create the front end in pure JavaScript.
Prerequisites
In this article you will build a Web application using Grails and Flex. The Grails framework is built on the Groovy programming language, a dynamic language for the Java™ platform. Familiarity with Groovy is great, but not completely necessary. Knowledge of Java can be a good substitute, or even other dynamic languages like Ruby or Python. Grails 1.0.3 was used with developing this article (see Resources). Grails can work with numerous databases or application servers, but none is needed for this article—Grails comes with both. The front end is built using Flex, an application framework that uses the ActionScript programming language and runs on the Flash Player. Again, it is okay if you are not already familiar with Flex and ActionScript. Familiarity with Java and JavaScript will help in picking up Flex. Flex SDK 3.2 or higher is needed to compile the code in this article (see Resources). To run the application, you need the Flash Player Version 10.0 or higher.. It turns out, however, that these two things work well together. You can use an SOA design to deploy services to your application servers. You can move all of your presentation logic to the client and leverage a powerful front-end technology such as Flex to create an RIA. That is exactly what you will do in this series, and you will start by creating a Web service using Grails.
Web services
When many developers hear the term Web service, they think of one thing: SOAP (Simple Object Access Protocol). This has a negative connotation with many developers, as they think of SOAP as being a heavy and complicated technology. However, Web services do not have to be that way. REST (Representational State Transfer)-style Web services have gained popularity because of their simple semantics. They are easier to create and to consume. They can use XML, just like SOAP services, but this can be Plain Old XML (POX) with no fancy wrappers and headers like with SOAP. The Grails framework makes it very easy to create these kind of Web services, so let's get started with a Grails domain model.
Grails domain model
Grails is a general purpose Web development framework. Most Web applications use a relational database to store and retrieve the data used in an application, and thus Grails comes with a powerful Object Relational Modeling (ORM) technology known as GORM. With GORM, you can easily model your domain objects and have them persisted to a relational database of your choice, without ever dealing with any SQL. GORM uses the popular Hibernate library for generating database-specific and optimized SQL, and for managing the life cycles of domain objects. Before getting in to using GORM, let's quickly discuss the application you will create and what you need to model with GORM.
In the sample application, you will create a Web application that mimics the functionality of the popular site Digg (see Resources). On Digg, users can submit links to stories (Web pages). Other users can then read these stories and vote for or against them. You will capture all of this basic functionality in your application. It will let people submit and vote for stories anonymously, so you will not need to model users, just stories. With that in mind, here is the GORM model for a story in the example application, shown in Listing 1.
Listing 1. The Story model
class Story { String link String title String description String tags String category int votesFor int votesAgainst }
That is all the code needed to model the domain object. You declare its properties and the types of those properties. This will allow Grails to create the table for you and dynamically create methods for both reading and writing data from that table. This is one of the major benefits of Grails. You only put data modeling code in one place and never have to write any boilerplate code for simple reads and writes. Now that you have the domain model in place, you can create some business services that use this domain model.
Business services
One of the benefits of an SOA is that it allows you to model your system in a very natural way. What are some of the operations you would like to perform? That is how you define the business services of the application. For example, you will want to be able to browse and search for stories, so you should create a service for this, as shown in Listing 2.
Listing 2. Search service
class SearchService { boolean transactional = false def list() { Story.list() } def listCategory(catName){ Story.findAllWhere(category:catName) } def searchTag(tag){ Story.findAllByTagsIlike("%"+tag+"%") } }
The
first thing you might notice is the boolean flag
transactional. Grails is built on top of numerous proven
technologies, including Spring. It uses Spring's declarative transactions
to decorate any service with transactions. If you were performing updates
on data, or you wanted this service to be used by other transactional
services, then you would want to enable this. You want this service to be a
read-only service. It is not going to take the place of data access, since
you have a domain model that already handles all of that.
The first
service operation retrieves all stories. The second retrieves those for a
given category. You use GORM's where-style finder for this. This lets you
pass in a map of name/value pairs to form a
WHERE clause in an SQL query. The third operation allows you to
search for stories with a given tag. Here you use GORM's dynamic finders.
This lets you incorporate the query clause as part of the name of the
finder method. So to query on the tags column, you use
findAllByTags. Also notice the
like
suffix; this is a case-insensitive
SQL LIKE clause. This lets you find
all stories where the tag parameter occurs as a substring of the tags
attribute. For example, if a story had been tagged "BarackObama" it would
show up in a search for "obama."
You have created three simple but powerful ways to search for stories. Notice how succinct the syntax for this is. If you are a Java programmer, just imagine how much you would normally write to do this. The search service is powerful, but there is nothing to search yet. You need another service for managing individual stories. I have called this the Story service, and it is shown in Listing 3.
Listing 3. Story service
class StoryService { boolean transactional = true def create(story) { story.votesFor = 0 story.votesAgainst = 0 log.info("Creating story="+story.title) if(!story.save(flush:true) ) { story.errors.each { log.error(it) } } log.info("Saved story="+story.title + " id=" + story.id) story } def voteFor(storyId){ log.info("Getting story for id="+storyId) def story = Story.get(storyId) log.info("Story found title="+story.title + " votesFor="+story.votesFor) story.votesFor += 1 if(!story.save(flush:true) ) { story.errors.each { log.error(it) } } story } def voteAgainst(storyId){ log.info("Getting story for id="+storyId) def story = Story.get(storyId) log.info("Story found title="+story.title + " votesAgainst="+story.votesAgainst) story.votesAgainst += 1 if(!story.save(flush:true) ) { story.errors.each { log.error(it) } } story } }
The
Story service has three operations. First, you can create a new story.
Next, you have operations for voting for and voting against a given story,
via the ID of the story. In each case, notice that you have done some
logging. Grails makes it easy to log—just use the implicit log object and
typical log4j-style methods:
log.debug,
log.info,
log.error, and so on. The story is saved (either inserted or
deleted) using the save method on the
Story
instance. Notice how you can check for errors by examining the errors
property of the story instance. For example, if the story was missing a
value for a required field, then this would show up as part of
story.errors. Finally notice that this service is transactional. This will
tell Grails (and thus Spring) to either use an existing transaction (if
one is already present), or create a new one whenever any of these
operations are invoked. This is particularly important for the voting
operations, because in those you have to read the story from the database
first and then update a column. Now that you have created your basic
business services, expose them as an API by creating a Web service
around them, as you'll see next.
Exposing the API
As developers, we often think of APIs as code that we write that will be called by other developers. In a Service Oriented Architecture, this is still true. However, the API is not a Java interface or something similar; it is a Web service signature. It is the Web service that exposes the API and allows it to be invoked by others. Grails makes it easy to create a Web service—it is just another controller in a Grails application. Take a look at Listing 4 to see the API for the application.
Listing 4. The API controller
import grails.converters.* class ApiController { // injected services def searchService def storyService // set the default action def defaultAction = "stories" def stories = { stories = searchService.list() render stories as XML } def submit = { def story = new Story(params) story = storyService.create(story) log.info("Story saved story="+story) render story as XML } def digg = { def story = storyService.voteFor(params.id) render story as XML } def bury = { def story = storyService.voteAgainst(params.id) render story as XML } }
The
first thing you will notice is the presence of the business services you
created in the previous section. These services will be automatically
injected by Grails. Actually, they were injected by the Spring framework,
one of the technologies that Grails is built on. You simply follow the
naming convention (
searchService for the
instance variable that will be used to reference an instance of the
SearchService class and so on), and Grails does
everything for you.
The API presents four operations (actions) that
can be called:
stories,
submit,
digg, and
bury. In each case, you delegate to a business
service, take the result of that call and serialize it to XML that you
send to the client. Grails makes this rendering easy, just using the
render function and an XML converter. Finally, notice that the
submit,
digg, and
bury actions all use the
params object. This is a hashtable of the HTTP
request parameters and their values. For the
digg and
bury, you simply retrieve
the
id parameter. For the
submit action, you passed the whole
params object to the constructor of the
Story class. This uses Grails data binding—as long
as the parameter names match up to the property names of the class, Grails
will set them for you. This is just another case of how Grails makes
development easier. You have written a very minimal amount of code, but
that was all you needed to create the services and expose them as Web
services. Now you can create a rich presentation layer that uses these
services.
Presentation
You have used an SOA for the back end of the application. This will allow you to create many different kinds of presentation layers on top of it. You will first build a Flash-based user interface using the Flex framework. However, you could just as easily use any other client-side presentation technology. You could even create a "thick" desktop client. However, there is no need, as you will be able to get a rich user experience from a Web client. Take a look at some simple use cases below, and build the user interface for them using Flex. Let's get started by listing all of the stories.
Listing stories
To list the stories,
you know what API to call from the back end. Or do you? When you created
the back end, did you ever map any particular URLs to your API controller
and its methods? Obviously you did not, but once again Grails will make
your life easier. It uses convention over configuration for this. So, to
call the stories action on the API controller for the digg application,
the URL will be
http://<root>/digg/api/stories. Since this is a RESTful
Web service, this should be an HTTP
GET. You
can do this in your browser directly and get XML that looks something like
the XML shown in Listing
5.
Listing 5. Sample XML response
<?xml version="1.0" encoding="UTF-8"?><list> <story id="12"> <category>technology</category> <description>This session discusses approaches and techniques to implementing Data Visualization and Dashboards within Flex 3.</description> <link>- 2008-data-visualization-and.php</link> <tags>flash, flex</tags> <title>Data Visualization and Dashboards</title> <votesAgainst>0</votesAgainst> <votesFor>0</votesFor> </story> <story id="13"> <category>technology</category> <description>Make your code snippets like really nice when you blog about programming.</description> <link> syntax-highlighting-and-code-snippets.html</link> <tags>programming, blogging, javascript</tags> <title>Syntax Highlighting and Code Snippets in a blog</title> <votesAgainst>0</votesAgainst> <votesFor>0</votesFor> </story> <story id="14"> <category>miscellaneous</category> <description>You need a get notebook if you are going to take good notes.</description> <link> sweet_decay.html</link> <tags>notebooks</tags> <title>Sweet Decay</title> <votesAgainst>0</votesAgainst> <votesFor>0</votesFor> </story> <story id="16"> <category>technology</category> <description>If there was one thing I could teach every engineer, it would be how to market. </description> <link></link> <tags>programming, funny</tags> <title>The One Thing Every Software Engineer Should Know</title> <votesAgainst>0</votesAgainst> <votesFor>0</votesFor> </story> </list>
Obviously, the exact contents depend on what data you have saved in your database. The important thing to note is the structure of how Grails serializes the Groovy objects as XML. Now you are ready to write some ActionScript code for working with the services.
Data access
One of the nice things about moving
all of the presentation tier to the client is that it is much cleaner
architecturally. It is easy to follow a traditional model-view-controller
(MVC) paradigm now, since nothing gets spread out between the server and
client. So you start with a model for representing the data structure and
then encapsulate access to the data. This is shown in the
Story class in Listing
6.
Listing 6.
Story class
public class Story extends EventDispatcher { private static const LIST_URL:String = ""; [Bindable] public var id:Number; [Bindable] public var title:String; [Bindable] public var link:String; [Bindable] public var category:String; [Bindable] public var description:String; [Bindable] public var tags:String; [Bindable] public var votesFor:int; [Bindable] public var votesAgainst:int; private static var listStoriesLoader:URLLoader; private static var dispatcher:Story = new Story(); public function Story(data:XML=null) { if (data) { id = data.@id; title = data.title; link = data.link; category = data.category; description = data.description; tags = data.tags; votesFor = Number(data.votesFor); votesAgainst = Number(data.votesAgainst); } } }
Listing
6 shows the basics of the
Story class. It has
several fields, corresponding to the data structure you will get from the
service. The constructor takes an optional XML object and populates its
fields from that object. Notice the succinct syntax for accessing the XML
data. ActionScript implements the E4X standard as a simplified way of
working with XML. It is similar to XPath, but uses a syntax that is more
natural for object-oriented programming languages. Also notice that each
property has been decorated with
[Bindable].
This is an ActionScript annotation. It allows a UI component to be bound
to the field, so that if the field changes, the UI is updated
automatically. Finally, notice the static variable,
listStoriesLoader. This is an instance of
URLLoader, an ActionScript class used for sending HTTP
requests. It is used by a static method in the
Story class for loading all of the stories via the API. This
is shown in Listing
7.
Listing 7. List Stories method
public class Story extends EventDispatcher { public static function list(loadHandler:Function, errHandler:Function=null):void { var req:URLRequest = new URLRequest(LIST_URL); listStoriesLoader = new URLLoader(req); dispatcher.addEventListener(DiggEvent.ON_LIST_SUCCESS, loadHandler); if (errHandler != null) { dispatcher.addEventListener(DiggEvent.ON_LIST_FAILURE, errHandler); } listStoriesLoader.addEventListener(Event.COMPLETE, listHandler); listStoriesLoader.addEventListener(IOErrorEvent.IO_ERROR, listErrorHandler); listStoriesLoader.load(req); } private static function listHandler(e:Event):void { var event:DiggEvent = new DiggEvent(DiggEvent.ON_LIST_SUCCESS); var data:Array = []; var storiesXml:XML = XML(listStoriesLoader.data); for (var i:int=0;i<storiesXml.children().length();i++) { var storyXml:XML = storiesXml.story[i]; var story:Story = new Story(storyXml); data[data.length] = story; } event.data = data; dispatcher.dispatchEvent(event); } }
The
list method is what the controller will be
able to invoke. It sends off an HTTP request and registers event listeners
for when that request completes. This is needed because any HTTP request
in Flash is asynchronous. When the request completes, the
listHandler method is invoked. This parses
through the XML data from the service, once again using E4X. It creates an
array of
Story instances and attaches this
array to a custom event that is then dispatched. Take a look at that
custom event in Listing
8.
Listing 8.
DiggEvent
public class DiggEvent extends Event { public static const ON_STORY_SUBMIT_SUCCESS:String = "onStorySubmitSuccess"; public static const ON_STORY_SUBMIT_FAILURE:String = "onStorySubmitFailure"; public static const ON_LIST_SUCCESS:String = "onListSuccess"; public static const ON_LIST_FAILURE:String = "onListFailure"; public static const ON_STORY_VOTE_SUCCESS:String = "onStoryVoteSuccess"; public static const ON_STORY_VOTE_FAILURE:String = "onStoryVoteFailure"; public var data:Object = {}; public function DiggEvent(type:String, bubbles:Boolean=false, cancelable:Boolean=false) { super(type, bubbles, cancelable); } }
Using a custom event class is a common paradigm in ActionScript development, because any server interactions have to be asynchronous. The controller can call the method on your model class and register its own event handlers that look for the custom events. You can decorate the custom event with extra fields. In this case you just added on a data field that is generic and can be reused. Now that you have looked at the model for the presentation tier, look at how it gets used by the controller.
Application controller
The controller is responsible for coordinating calls to the model, providing the model to the view, and responding to events from the view. Take a look at the controller code in Listing 9.
Listing 9.
DiggController
public class DiggController extends Application { [Bindable] public var stories:ArrayCollection; [Bindable] public var subBtnLabel:String = 'Submit a new Story'; public function DiggController() { super(); init(); } private function init():void { Story.list(function(e:DiggEvent):void{ stories = new ArrayCollection(e.data as Array);}); } }
The
controller extends the core Flex class
Application. This is an idiomatic approach to Flex that lets
you associate the controller to its view in a simple way, as you will see
in the next section. The controller has a collection of stories that is
bindable. This will let the collection be bound to UI controls. Once the
application loads, it immediately calls the
Story.list method. It passes an anonymous function or lambda,
as a handler to the
Story.list method. The
lambda expression simply dumps the data from the custom event into the
stories collection. Now take a look at how this is used in the
view.
The view
Earlier I mentioned that the controller extended the
Flex
Application class. This is the base class
of any Flex application. Flex allows you to use MXML (an XML dialect) to
declaratively create the UI. The controller is able to leverage this
syntax, as shown in Listing
10.
Listing 10. User interface
<?xml version="1.0" encoding="utf-8"?> <ctrl:DiggController xmlns: <mx:Script> <![CDATA[ import org.developerworks.digg.Story; private function digg():void { this.diggStory(results.selectedItem as Story); } private function bury():void { this.buryStory(results.selectedItem as Story); } ]]> </mx:Script> <ctrl:states> <mx:State <mx:AddChild <works:StoryEditor </mx:AddChild> </mx:State> </ctrl:states> <mx:DataGrid <mx:HBox <mx:Button <mx:Button <mx:Button </mx:HBox> </ctrl:DiggController>
Notice
that the root document uses the "ctrl" namespace. This is declared to
point to the "controllers" folder, and that is where you put your controller
class. Thus everything from the controller class is available inside the
UI code. For example, you have a data grid whose
dataProvider property is set
stories. This is the stories
variable from the controller class. It directly binds to the DataGrid
component. Now you can compile the Flex code into a SWF file. You just
need a static HTML file for embedding the SWF. Running it will look
something like Figure 1.
Figure 1. The Digg application
This is the default look and feel of a Flex application. You can easily style the colors using standard CSS like you would use for an HTML application. You can also customize the DataGrid component, specifying the columns, their order, and so on. The "Digg the Story!" and "Bury the Story!" buttons both call functions on the controller class. Also, notice that you wire-up a controller function to the double-click event for the DataGrid. The controller methods all use the model, just as you would expect in an MVC architecture. The final button, "Submit a new Story", uses several key features of Flex. Take a look at how it works.
Submit a story
As you can see in
Listing 10, clicking the "Submit a new Story" button invokes the
toggleSubmitStory method on the controller class.
The code is shown in Listing
11.
Listing 11. The
toggleSubmitStory method
public class DiggController extends Application { public function toggleSubmitStory():void { if (this.currentState != 'SubmitStory') { this.currentState = 'SubmitStory'; subBtnLabel = 'Nevermind'; } else { this.currentState = ''; subBtnLabel = 'Submit a new Story'; } } }
This
function changes the
currentState property of
the application to
SubmitStory. Looking back at
Listing 10, you can see where this state is defined. States allow you to
add or remove components, or to set properties on existing components. In
this case you add a new component to the UI. That component happens to be a
custom component for submitting a story. It is shown in Listing
12.
Listing 12. The StoryEditor component
<?xml version="1.0" encoding="utf-8"?> <mx:VBox xmlns: <mx:Form> <mx:FormHeading <mx:FormItem <mx:TextInput </mx:FormItem> <mx:FormItem <mx:TextInput </mx:FormItem> <mx:FormItem <mx:ComboBox </mx:FormItem> <mx:FormItem <mx:TextArea </mx:FormItem> <mx:FormItem <mx:TextInput </mx:FormItem> <mx:Button </mx:Form> <mx:Binding <mx:Binding <mx:Binding <mx:Binding <mx:Binding </mx:VBox>
Listing
12 only shows the UI elements for the custom component. It is just a
simple form, but notice the binding declarations in it. This allows you to
directly bind the UI form elements to a
Story
instance, called story. That is declared in a script block, as shown in
Listing
13.
Listing 13. Script for StoryEditor
<?xml version="1.0" encoding="utf-8"?> <mx:VBox xmlns: <mx:Script> <![CDATA[ import mx.controls.Alert; import org.developerworks.digg.*; [Bindable] private var story:Story = new Story(); public var successHandler:Function; private function submitStory():void { story.addEventListener(DiggEvent.ON_STORY_SUBMIT_SUCCESS, successHandler); story.addEventListener(DiggEvent.ON_STORY_SUBMIT_FAILURE, errorHandler); story.save(); // reset story = new Story(); } private function errorHandler(e:Event):void { Alert.show("Fail! : " + e.toString()); } ]]> </mx:Script> </mx:VBox>
The script block acts as the controller code for the component. You could easily put both into a separate controller class for the component, since both styles are common in Flex. Going back to Figure 1, you can click on the "Submit new Story" button, and it will show the custom component, as shown in Figure 2.
Figure 2. Custom component displayed
You can add a new story using the component. It will call the back-end
service, which will return XML for the story. That is, in turn, converted
back to a
Story instance and added to the stories
collection that is bound to the DataGrid, making it automatically appear
in the UI. With that, the presentation code is complete and hooked up to
the back-end service.
Summary
In this article you have seen how easy it is to create a Web service with Grails. You never had to write any SQL to create a database or to read and write from it. Grails makes it easy to map URLs to Groovy code and to invoke services and create XML for the Web service. This XML is easily consumed by a Flex front end. You have seen how to create a clean MVC architecture on the front end and how to use many sophisticated features of Flex, like E4X, data-binding, states, and custom components.
In Part 2 of this series, explore using a JavaScript-based UI for the service using the Google Web Toolkit.

Current state: Accepted
JIRA: KAFKA-4148
Released: 0.10.1.0
Please keep the discussion on the mailing list rather than commenting on= the wiki (wiki discussions get unwieldy fast).
This KIP includes two parts:
With KIP-33, the = brokers can now search messages by timestamp accurately. To maintain the ba= ckwards compatibility, we did not change the behavior of ListOffse= tRequest v0. In this KIP, we will introduce ListOffsetRequest v1 t= o provide more accurate search based on timestamp.
In SimpleConsumer, users used to be able to search the offsets by = timestamp. This method no longer exists in the KafkaConsumer. We want to in= troduce the method to allow user to search the offsets by timestamp. This i= s useful in a few cases, for example:
Another related feature missing in KafkaConsumer is the access of partit= ions' high watermark. Typically, users only need the high watermark in orde= r to get the per partition lag. This seems more suitable to be exposed thro= ugh the metrics.
Although the above two parts can be two separate KIPs, but since part 2 = will be heavily depending on part 1 and may also potentially impact the sem= antic for the ListOffsetRequest v1, it might be better to discuss them toge= ther to make sure the wire protocol change can satisfy the various use case= s on the consumer side.
Add ListOffsetRequest(ListOffsetRequest) v1
// ListOffsetRequest v1 <=
/p>
ListOffsetRequest =3D> Replica= Id [TopicName [Partition Time
=
MaxNumberOfOffsets]]
ReplicaId =3D> int32&nbs= p;
TopicName =3D> string
Partition =3D> int= 32
Time =3D> int64
MaxNumberOfOffsets =3D> int32
// ListOffsetResponse v1 <=
/code>
ListOffsetResponse =3D> [TopicName [PartitionOffs=
ets]]
PartitionOffsets =3D> Partition Error=
Code Timestamp
Partition =3D> int3=
2
ErrorCode =3D> int16
Offset =3D> int64
Add new Error Code 43 - UnsupportedForMessageFormat
This error code is added to indicate that the requested operation is not= supported by the message format version. In this KIP it means the ti= mestamp search operation is not supported by the message format before 0.10= .0 when ListOffsetRequest is v1. This error code could also be used in the = future when message format evolves again. (e.g. KIP-82).
Add a new method to o.a.k.c.consumer.Consumer to allow user sear= ch offsets by timestamp.
/** * Look up the offsets for the given partitions by timestamp. The returned = offset for each partition is the=20 * earliest offset whose timestamp is greater than or equals to the given t= imestamp in the corresponding partition. *=20 * This is a blocking call. The consumer does not have to be assigned the p= artitions. * * @param timestampsToSearch the mapping from partition to the timestamp to= look up. * @return For each partition, returns the timestamp and offset of the firs= t message with timestamp greater * than or equal to the target timestamp. */ Map<TopicPartition, OffsetAndTimestamp> offsetsForTimes(Map<TopicP= artition, Long> timestampsToSearch); /** * Get the earliest available offsets for the given partitions. *=20 * @param partitions the partitions to get the earliest offsets. * @return The earliest available offsets for the given partitions */ Map<TopicPartition, Long> beginningOffsets(Collection<TopicPartiti= on> partitions); /** * Get the latest offsets for the given partitions. *=20 * @param partitions the partitions to get the latest offsets. * @return The latest available offsets for the given partitions. */ Map<TopicPartition, Long> endOffsets(Collection<TopicPartition>= partitions); public class OffsetAndTimestamp { =09private final long timestamp; =09private final long offset; =09public OffsetAndTimestamp(long offset, long timestamp) { =09=09this.timestamp =3D timestamp; =09=09this.offset =3D offset; =09} =09public long timestamp() { return timestamp; } =09public long offset() { return offset; } }=20
Add ListOffsetRequest/ListOffsetResponse v1 with the following cha= nges compared with ListOffsetRequest/ListOffsetResponse v0
In ListOffsetRequest/ListOffsetResponse v0, we return a list of offsets =
which is smaller than or equals to the target time. This was because the ti=
mestamp search is based on the segment create time. In order to make sure n=
ot to miss any messages, users may have to consume from some earlier segmen=
ts. After KIP-33, we can accurately find the messages based on the timestam=
ps, so there is no need to return a list of offsets to the users anymore. A=
rguably we can change the request class name to
OffsetRequest =
as well because it no longer "list" the offsets, but it seems not worth bre=
aking the backwards compatibility in this case.
Also, since the messages in format 0.10 and above has timestamp with the= m, it would be natual to also return the timestamp together with the offset= of the messages as the search result.
The semantic of getting the latest offset (target time =3D -1) and the e= arliest offset (target time =3D -2) will be preserved in ListOffsetRequest/= ListOffsetResponse v1.
If message format on the broker side is before 0.10, i.e. messages do no= t have timestamps. ListOffsetRequest v1 will only work if target time =3D -= 1 or -2. Any other target time will result in an UnsupportedForMessageForma= t (error code 43).
Implementation wise, we will migrate to o.a.k.common.requests.ListOffset= Request class on the broker side.
Because Kafka request schema uses an
Array to represent a <=
code>Map, it is possible that users form a
ListOffsetRequest=
code> that contains duplicate partitions with differen timestamps. In this =
case, the broker will return an InvalidRequestException(error code 42) for =
that partition in the
ListOffsetResponse.
Add a new method to allow users to search messages by timestamp. The inp= ut of the method is a mapping from partitions to the target times. The outp= ut of the method is a mapping from partitions to the timestamps and offsets= of the messages whose timestamps are greater than or equal to the given ta= rget time of each partition.
The most important use case for
offsetsForTimes() =
;method is to consume from the returned offsets. The following code gives a=
n example to do that:
long offset = =3D consumer.offsetsForTimes(Collections.singletonMap(topicPartition, targe= tTime)).get(topicPartition).offset; consumer.seek(topicPartition, offset); ConsumerRecords records =3D consumer.poll();=20
The target timestamp have to be non-negative. Otherwise an
Illegal=
ArgumentException will be thrown. If no message has a timestamp that=
is greater than or equals to the target time, a n
ull will be =
returned.
earlistOffsets() and
endOffsets() return the f=
irst and last offset for the given partitions.
This KIP is a pure addition, so there is no backward compatibility conce= rn.
The new ListOffsetRequest v1 will only be used by new consumer. The old = high level consumer will still be using ListOffsetRequest v0. We will not u= pdate SimpleConsumer either as we are already in the progress of deprecatin= g it. OffsetRequest(ListOffsetRequest) v0 will be deprecated together = with old high level consumer and SimpleConsumer.
Test the new consumer against broker with message format before and afte= r 0.10.

So I've had a quick look around and I've seen some posts about not using loops in IEnumerators, however after reading the information available on the scripting reference there's nothing that I can see about them being particularly resource heavy or incorrect, so I figured I'd ask here.
This is the script I'm using for testing:
using UnityEngine;
using System.Collections;
using UnityEngine.UI;
public class iEnumeratorTest : MonoBehaviour
{
public bool isRecording;
public float recordingTime;
public float timeTaken;
public float tickTime;
void Update()
{
if (isRecording)
{
recordingTime += Time.deltaTime;
}
else
{
if (recordingTime != 0f)
{
Debug.Log("That took: " + recordingTime);
recordingTime = 0f;
}
}
}
public void ButtonClick()
{
StartCoroutine(Tick());
}
IEnumerator Tick()
{
isRecording = true;
for (float f = timeTaken; f >= 0; f -= tickTime)
{
yield return new WaitForSeconds(tickTime);
}
isRecording = false;
}
}
Update() returns values roughly 10-15% higher than the time it should take to wait. For example, when tickTime was set to 0.1 and timeTaken set to 5, results returned varied between 5.15234 and 5.657412. The results have been similar when using both while and for loops and the actual time is closer to the desired time when increasing tickTime and decreasing timeTaken. This wouldn't be such a big deal however as the wait times are intended to increase dramatically towards the end 10-15% is a great deal of time to be wasted.
2 facts you should know.
1) Coroutines will halt a main thread
2) Frame times vary and it is impossible to get an exact wait time as a result :- Especially when your frames are lengthened by waiting on a coroutine.

This is due to how Coroutines and WaitForSeconds works. A coroutine is run together with Update, until it's done. If a coroutine yields another IEnumerator, that one is called until it's done, before the main coroutine starts getting called.
WaitForSeconds is implemented somewhat like this:
IEnumerator WaitForSeconds(float duration) {
float startTime = Time.Time;
while(Time.time - startTime < duration)
yield return null;
}
This means that it will return on the first Update frame that more time than the duration has passed.
Since this is inevitably more than exactly the duration given as the argument, each WaitForSeconds will add a slight positive error. So, the lower your ticktime, the larger the error.
This isn't actually a big problem - if you want to wait 5 seconds, use WaitForSeconds(5). The effect won't kick in at exactly 5 seconds, but it will kick in at the first frame that's drawn after 5 seconds has passed, so it will look exactly the same as if you somehow magically managed to make the coroutine return at exact 5 seconds.
The only reason I'm using a tick system is so I can have a bar fill up gradually while reducing unnecessary resource usage in update, any idea if I can still do this without using IEnumerators or update?
Yeah, you set the bar's fill to the current fill percentage:
bar.fillAmount = (Time.time - startTime) / duration;
Where I assume fillAmount is between 0 and 1.
In general, if you have a UI bar (or element) that's reflecting some variable in a script, you shouldn't have the script both update the value, and keep the bar filled - that'll lead to your script getting huge, and possible introduce bugs where the two gets seperated.
Ins$$anonymous$$d, you should put a new script on the bar that looks at the value in the first script, and fills the bar according to that, blind to what the value actually is representing.
Filling the bar was never an issue, deciding when to do it was the issue since the previous solution was inaccurate. Having a separate script for essentially 2 lines of code and reading across scripts each frame is going to end up even more inefficient, guess the only other solution is on Update(). Thanks again for the help.

The 'Update' method not depend of time. It's called when the camera render was completed. Your coroutine wait fix seconds, so there are some difference. Try frame base coroutine:
IEnumerator Tick() {
isRecording = true;
float f = 0;
while (f <= timeTaken) {
yield return new WaitForEndOfFrame();
f += Time.deltaTime;
}
isRecording = false;
}

Chapter 0: Learn OpenTK in 15'
So, you have downloaded the latest version of OpenTK - what now?
This is a short tutorial that will help you get started with OpenTK in 3 simple steps.
[Step 1: Installation]
Run the installer you downloaded. It will ask where you want OpenTK to be installed. Any folder will do.
[Step 2: Use OpenTK]
Create a new project in your .NET IDE (don't have a .NET IDE? Check out MonoDevelop or Visual Studio Express). Make it of type "Console Application".
Now, add a reference to OpenTK.dll: In your new project, right click "References" and select "Add Reference". Locate OpenTK.dll and add it.
Repeat this process for System.Drawing.dll. OpenTK depends on this.
Now you are ready to add some graphics! Open Program.cs and copy-paste the following code:
using System; using System.Drawing; using OpenTK; using OpenTK.Graphics; using OpenTK.Graphics.OpenGL; using OpenTK.Input; namespace Example { class MyApplication { [STAThread] public static void Main() { using (var game = new GameWindow()) {); } } } }
Build and run this application. You should see a window with a triangle inside. Press escape to exit.
[Step 3: Play]
Now it's time to start playing with the code. This is a great way to learn OpenGL and OpenTK at the same time.
Every OpenTK game will contain 4 basic methods:
Load: this is the place to load resources from disk, like images or music.
UpdateFrame: this is a suitable place to handle input, update object positions, run physics or AI calculations.
RenderFrame: this contains the code that renders your graphics. It typically begins with a call to
GL.Clear()and ends with a call to
SwapBuffers.
Resize: this method is called automatically whenever your game window changes size. Fullscreen applications will typically call it only once. Windowed applications may call it more often. In most circumstances, you can simply copy & paste the code from Game.cs.
Why don't you try modifying a few things? Here are a few suggestions:
- Change the colors of the triangle or the window background (OnLoad and OnRenderFrame methods). Hint: use GL.Color4() to control the triangle color and GL.ClearColor() to control the background color.
- Make the triangle change colors when you press a key (OnUpdateFrame and OnRenderFrame methods).
- Make the triangle move across the screen. Use the arrow keys or the mouse to control its position (OnUpdateFrame). Hint: use Matrix4.CreateTranslation() to create a translation matrix and call GL.LoadMatrix() to load it (OnRenderFrame).
- Use a for-loop to render many triangles arranged on a plane (OnRenderFrame method).
- Rotate the camera so that the plane above acts as ground (OnRenderFrame method). Hint: use Matrix4.LookAt() to create a modelview matrix and use GL.LoadMatrix() to load it.
- Use the keyboard and mouse to walk on the ground. Make sure you can't fall through it! (OnUpdateFrame and OnRenderFrame methods).
Some things you might find useful:
Vector2,
Vector3,
Vector4 and
Matrix4 classes for camera manipulations.
Mouse and
Keyboard properties for interaction with the mouse and keyboard, respectively.
Joysticks property for interaction with joystick devices.
Don't be afraid to try things and see the results. OpenTK lends itself to explorative programming - even if something breaks, the library will help you pinpoint the cause of the error.
[Step: next]
There's a lot of functionality that is not visible at first glance: audio, advanced OpenGL, display devices, support for GUIs through GLControl... Then there's the subject of proper engine and game design, which could cover a whole book by itself.
Hopefully, you'll have gained a feel of the library by now and you'll be able to accomplish more complex tasks. You might wish to consult the complete documentation for the more advanced aspects of OpenTK and, of course, don't hesitate to post at the forums if you hit any roadblocks!

Re: Chapter 0: Learn OpenTK in 15'
This is nice. However I have a question. I am working on Windows 7 but would like to create a graphics program that will run in both windows and Linux Desktop so I would like to try it with c# mono. When i try create a project in vs2008 using the sample here, it works and it runs successfully. But if i run the sample here in Xamarin Studio 4.0 (still in Windows 7), and when I run it, the compiler throws me an error which looks like its trying to look for x11 (libx11). What setting is missing when the project is loaded in Xamarin Studio. Is there a way to make it work seamless across desktop environments of windows and linux?
thank you

Programming a Spider in Java
Introduction
Spiders are programs that can visit Web sites and follow hyperlinks. By using a spider, you can quickly map out all of the pages contained on a Web site. This article will show you how to use the Java programming language to construct a spider. A reusable spider class that encapsulates a basic spider will be presented. Then, an example will be shown of how to create a specific spider that will scan a Web site and find broken links.
Java is a particularly good choice as a language to construct a spider. Java has built-in support for the HTTP protocol, which is used to transfer most Web information. Java also has an HTML parser built in. Both of these two features make Java an ideal choice for spiders.
Using the Spider
Now, you will be shown how this example program communicates with the reusable spider class. The example program is contained in the CheckLinks class, as seen in Listing 1. This class implements the ISpiderReportable interface, as seen in Listing 2. This interface allows the Spider class to communicate with the example application. This interface defines three methods. The first method, named "spiderFoundURL", is called each time the spider locates a URL. Returning true from this method indicates that the spider should pursue this URL and find links there as well. The second method, named "spiderURLError", is called when any of the URLs that the spider is examining results in an error (such as a 404 "page not found"). The third method, named "spiderFoundEMail", is called by the spider each time an e-mail address is found. By using these three methods, the Spider class is able to communicate its findings back to the application that created it.
The spider begins processing when the begin method is clicked. To allow the example program to maintain its User Interface, the spider is started up as a separate Thread. Clicking the "Begin" button begins this background spider thread. When the background thread begins, the run method of the "CheckLinks" class is called. The run method begins by instantiating the Spider object. This can be seen here:
spider = new Spider(this); spider.clear(); base = new URL(url.getText()); spider.addURL(base); spider.begin();
First, a new Spider object is instantiated. The Spider object's constructor requires that an "ISpiderReportable" object be passed to it. Because the "CheckLinks" class implements the "ISpiderReportable" interface, you simply pass it as the current object, represented by the keyword this, to the constructor. The spider maintains a list of URLs it has visited. The "clear" method is called to ensure that the spider is starting with an empty URL list. For the spider to do anything at all, one URL must be added to its processing list. The base URL, the URL that the user entered into the example program, is added to the initial list. The spider will begin by scanning this page, and will hopefully find other pages linked to this starting URL. Finally, the "begin" method is called to start the spider. The begin method will not return until the spider is done, or is canceled.
As the spider runs, the three methods implemented by the "ISpiderReportable" interface are called to report what the spider is currently doing. Most of the work done by the example program is taken care of in the "spiderFoundURL" method. When the spider finds a new URL, it is first checked to see if it is valid. If this URL results in an error, the URL is reported as a bad link. If the link is found to be valid, the link is examined to see if it is on a different server. If the link is on the same server, the "spiderFoundURL" method returns true, indicating that the spider should pursue this URL and find other links there. Links on other servers are not scanned for additional links because this would cause the spider to endlessly browse the Internet, looking for more and more Web sites. The program is looking for links only on the Web site that the user indicated.
Constructing the Spider Class
The previous section showed you how to use the Spider class, as seen in Listing 3. Using the Spider class and the "ISpiderReportable" interface can easily allow you to add spider capabilities to your own programs. This section will show you how the Spider class actually works.
The Spider class must keep track of which URLs it has visited. This must be done so that the spider insures that it does not visit the same URL more than once. Further, the spider must divide these URLs into three separate classes. The first group, stored in the "workloadWaiting" property, contains a list of URLs that the spider has encountered, yet has not had an opportunity to process yet. The first URL that the spider is to visit is placed into this collection to allow the spider to begin. The second group, stored in the "workloadProcessed" collection, is the URLs that the spider has already processed and does not need to revisit. The third group, stored in the "workloadError" property, contains the URLs that resulted in an error.
The begin method contains the main loop of the Spider class. The begin method repeatedly loops through the "workloadWaiting" collection and processes each page. Of course, as these pages are processed, other URLs are likely added to the "workloadWaiting" collection. The begin method continues this process until either the Spider is canceled, by calling the Spider class's cancel method, or there are no URLs remaining in the "workloadWaiting" method. This process is shown here:
cancel = false; while ( !getWorkloadWaiting().isEmpty() && !cancel ) { Object list[] = getWorkloadWaiting().toArray(); for ( int i=0;(i<list.length)&&!cancel;i++ ) processURL((URL)list[i]); }
As the preceding code loops through the "workloadWaiting" collection, it passes each of the URLs that are to be processed to the "processURL" method. This method will actually read and then parse the HTML stored at each URL.
Reading and Parsing HTML
Java contains support both for accessing the contents of URLs and parsing HTML. The "processURL" method, which is called for each URL encountered, does this. Reading the contents of a URL is relatively easy in Java. The following code, from the "processURL" method, begins this process.
URLConnection connection = url.openConnection(); if ( (connection.getContentType()!=null) && !connection.getContentType().toLowerCase() .startsWith("text/") ) { getWorkloadWaiting().remove(url); getWorkloadProcessed().add(url); log("Not processing because content type is: " + connection.getContentType() ); return; }
First, a "URLConnection" object is constructed from whatever URL, stored in the variable "url", was passed in. There are many different types of documents found on Web sites. A spider is only interested in those documents that contain HTML, specifically text-based documents. The preceding code makes sure that the content type of the document starts with "text/". If the document type is not textual, the URL is removed from the waiting workload and added to the processed workload. This ensures that this URL will not be investigated again.
Now that a connection has been opened to the specified URL, the contents must be parsed. The following lines of code allow you to open the URL connection, as though it were a file, and read the contents.
InputStream is = connection.getInputStream(); Reader r = new InputStreamReader(is);
You now have a Reader object that you can use to read the contents of this URL. For this spider, you will simply pass the contents onto the HTML parser. The HTML parser that you will use in this example is the Swing HTML parser, which is built into Java. Java's support of HTML parsing is half-hearted at best. You must override a class to gain access to the HTML parser. This is because you must call the "getParser" method of the "HTMLEditorKit" class. Unfortunately, Sun made this method protected. The only workaround is to create your own class and override the "getParser" method, to make it public. This is done by the provided "HTMLParse" class, as seen in Listing 4.
import javax.swing.text.html.*; public class HTMLParse extends HTMLEditorKit { public HTMLEditorKit.Parser getParser() { return super.getParser(); } }
This class is used in the "processURL" method of the Spider class, as follows. As you can see, the Reader object (r) that was obtained to read the contents of the Web page is passed into the "HTMLEditorKit.Parser" object that was just obtained.
HTMLEditorKit.Parser parse = new HTMLParse().getParser(); parse.parse(r,new Parser(url),true);
You will also notice that a new Parser class is constructed. The Parser class is an inner class to the Spider class provided in the example. The Parser class is a callback class that contains certain methods that are called as each type of HTML tag is found. There are several callback methods, which are documented in the API documentation. There are only two that you are concerned with in this article. These are the methods called when a simple tag (a tag with no ending tag, such as <br>) and a begin tag are found. These two methods are named "handleSimpleTag" and "handleStartTag". Because the processing for each is identical, the "handleStartTag" method is programmed to simply call the "handleSimpleTag". The "handleSimpleTag" method is then responsible for extracting hyperlinks from the document. These hyperlinks will be used to locate other pages for the spider to visit. The "handleSimpleTag" method begins by checking to see whether there is an "href", or hypertext reference, on the current tag being parsed.
String href = (String)a.getAttribute(HTML.Attribute.HREF); if( (href==null) && (t==HTML.Tag.FRAME) ) href = (String)a.getAttribute(HTML.Attribute.SRC); if ( href==null ) return;
If there is no "href" attribute, the current tag is checked to see if it is a Frame. Frames point to their pages using an "src" attribute. A typical hyperlink will appear as follows in HTML:
<a href="linkedpage.html">Click Here</a>
The "href" attribute in the above link points to the page be linked to. But the page "linkedpage.html" is not an address. You couldn't type "linkedpage.html" into a browser and go anywhere. The "linkedpage.html" simply specifies a page somewhere on the Web server. This is called a relative URL. The relative URL must be resolved to a full, absolute URL that specifies the page. This is done by using the following line of code:
URL url = new URL(base,str);
This constructs a URL, where str is the relative URL and base is the page that the URL was found on. Using this form of the URL class's constructor allows you to construct a full, absolute URL. With the URL now in its correct, absolute form, the URL is checked to see whether it has already been processed, by making sure it's not in any of the workload collections. If this URL has not been processed, it is added to the waiting workload. Later on, it will be processed as well and perhaps add other hyperlinks to the waiting workload.
Conclusions
This article showed you how to create a simple spider that can visit every site on a Web sever. The example program presented here could easily be a starting point for many other spider programs. More advanced spiders, ones that must handle a very large volume of sites, would likely make use of such things as multi-threading and SQL databases. Unfortunately, Java's built-in HTML parsing is not multi-thread safe, so building such a spider can be a somewhat complex task. Topics such as these are covered in my book Programming Spiders, Bots and Aggregators in Java, by Sybex.

Introduction
The new state management and postback features of ASP.NET are indeed very exciting. They provide developers with a whole new range of mechanisms for producing dynamic Web pages. The ability to write your own custom controls takes that ability to a whole new level, allowing you to write a control with custom functionality that can easily be reused in multiple pages by simply defining custom tags, similar to any other HTML element. The person implementing the layout for a page no longer needs to know all the details of how to write client-side code to get the dynamic behavior that has become so popular. However, there are some pitfalls that developers need to be aware of. ASP.NET promotes server-heavy designs. Network traffic can be dramatically increased as each client-side event can potentially cause a round trip to the server. Many of the effects that result from these frequent trips to the server can easily be accomlished with a few simple JavaScript functions. Calls to the server should be kept to a minimum, with as much being done on the client as possible. By using custom controls to generate client-side script, we can take advantage of Dynamic HTML on the client while still providing a measure of separation between the layout and the logic.
Client-Side Script Generation
One of the goals of generating script from a custom control is to allow a developer to create the control and specify its behavior, and then publish it for others to use without having to know how the code works. We want to encapsulate the implementation of the control and tightly couple the HTML rendering to the script that works with it to reduce the possible points of failure associated with more traditional methods of Web component reuse (such as Cut & Paste, and include files). The most straightforward approach to script generation is to write the script along with the control in the Render method of your control (see Listing 1).
namespace Spotu { public class HelloWorld : Control { protected override void Render ( HtmlTextWriter writer ) { writer.Write(@" <script> function HelloWorld() { document.all('_msg')." + "Click Me</button>"); writer.Write("<div id=_msg></div>"); } } }
Listing 2 shows an example of a page using the HelloWorld class with client script generation.
<%@ Page language="c#" %> <%@ Register <spotu:HelloWorld </form> </body> </html>
Listing 2: Page using the HelloWorld class.
This approach works, and does solve the initial problem of allowing a developer to write a custom control that someone else can use in their page to provide dynamic capabilities without having to post back to the server. However, it is not very elegant, and it does have some shortcomings. Most notably, we cannot include this control in a page multiple times; doing so would cause mutiple divisions to be created with the same ID. Even if we do uniquely name the <div> elements in this example, it is still inneficient because the JavaScript gets written out with every reference to this control. This can produce a lot of overhead, transmitting the same script down to the client for each instance of the control.
We need some way to have a control generate script, but generate it only once, even if multiple instances of the control are used on the same page. Fortunately for us, the developers at Microsoft thought of this and provided a way to register a script block to ensure we only write out a section of script once by using the Page.RegisterClientScriptBlock method. This method takes two parameters, an ID that identifies the script block so the Page class will know to ignore any other requests to register the same clock of code, and a string containing the script to be registered. The best place to register the script block is in the Init Event Handler for the control. To take advantage of this event, override the OnInit method of the Control class. With this in mind, the HelloWorld example could be rewritten as shown in Listing 3.
using System; using System.Web; using System.Web.UI; namespace Spotu { public class HelloWorld : Control { protected override void OnInit(EventArgs e) { string strCode = @" <script> function HelloWorld(id) { document.all(id)." + "Click Me</button>"); writer.Write("<div id='" + this.UniqueID + "'></div>"); } } }
Listing 3: HelloWorld rewritten to use the register script block.
This approach is much better but there is still a problem. If the script that is being register is lengthy, or if there are a lot of calculations, data accesses, and so forth in generating our script, we will still take a performance hit when the page loads because the control creates this huge block of script that ends up being tossed out because it is already registered. Once a block of script is registered, we can test for it using the
Page.IsClientScriptBlockRegistered method. To improve the performance of the HelloWorld control, we would include the call in out Init handler as shown in Listing 4.
protected override void OnInit(EventArgs e) { if (!Page.IsClientScriptBlockRegistered("Spotu_HelloWorld")) { string strCode = @" <script> function HelloWorld(id) { document.all(id).innerText = 'Hello World'; } </script>"; Page.RegisterClientScriptBlock("Spotu_HelloWorld", strCode); } }

Using client script generation from custom controls provides a clean encapsulated method of enabling dynamic behavior in Web pages while still shielding the page designer from having to know the details of how to produce the desired effect. Developers are now free to concentrate on how to get a control to do what you want it to do without being bogged down with were to put it on the page, or being pestered by the marketing guy to move a control around, add a new one, or take one away. By combining this approach with designer integration controls, dynamic behaviors can easily be customized and reused across multiple pages with little or no developer interaction and without the pitfalls of server-side includes or cut & paste code reuse.
Caching
Some of you might be inclined to ask: How do I cache this script so it doesn't get downloaded every time? After all, client-side script tends to be fairly static, not needing to be downloaded every time a Web page is loaded.
There are a couple of options for caching the output of your control. The ASP.NET approach would be to take advantage of output caching. There are a myriad of output caching options, but most of them place the responsibility of setting up that caching on the person doing the presentation by using directives and flags in the .aspx page. Also, caching the entire page may not be the desired effect. Some pages are extremely dynamic. In such cases, the ideal would be to just cache the control, or some portion of the control. ASP.NET does have some support for this, but that support is reserved primarily for user controls (.ascx files), which doesn't provide the reuse we are looking for.
For custom controls providing generated script, we may want to consider using an external script file. As we have already noted, most script does not change often, if at all and can readily be cached on the client. Instead of writing out the script directly from our custom control, we can instead place the script in an external script file and simply write out a <script..> tag with a src="." attribute that references our script file. This allows the control and the page to fluctuate as often as necessary without incurring the network traffic of always downloading the script to the client. The primary drawback to the approach is the deployment. There are now two files that need to be deployed to use the control in a page and the .js file must be reachable from the page that is using it. Relative paths don't always work because each page that uses the control may be at a different level. One deployment solution is to create a directory at the top level of your application (example: includes) and reference it in your control using Request.ApplicationPath + "/includes/<your script file here>". Another approach might be to provide custom properties on you control so the location of the external source file can be specified in the .aspx page. Listing 5 is an example of a calculator implemented using this approach.
using System; using System.Web; using System.Web.UI; using System.Collections.Specialized; namespace Spotu { public class Calculator : Control, IPostBackDataHandler { const string", this.UniqueID, sc_strStyleClass); _strOpButton = string.Format("<button " + "onclick='javascript:g_{0}.OnOperator(this.innerText);' " + "class='{1}'>", this.UniqueID, sc_strStyleClass); if (_strScriptSrc == null) { _strScriptSrc = Context.Request.ApplicationPath + "/includes/calc.js"; } if (_strStyleHref == null) { _strStyleHref = Context.Request.ApplicationPath + "/includes/calcStyle.css"; } string</link>"; Page.RegisterClientScriptBlock("Spotu_Calculator_Style", strStyle); } // End OnInit // Load Event Handler. Retrieve the value posted in the // display field of the calculator so we can keep the // state of the display regardless of how the form is // submitted. protected override void OnLoad ( EventArgs e ) { if (Page.IsPostBack) { _intCalcValue = Int32.Parse(Context.Request.Form[UniqueID + "_display"]); } } // End OnLoad // Render out the control protected override void Render ( HtmlTextWriter writer ) { string strHtml = string.Format(@" <script> var g_{0} = new Calc('{0}_display'); </script> <table> <tr colspan='*'> <input type='text' name='{0}_display' readonly=true value={4}> </input> </tr> <tr><td>{1}7</button></td> <td>{1}8</button></td> <td>{1}9</button></td> <td>{2}/</button></td> <td> <button class='{3}' onclick='javascript:g_{0}.OnClear();'> C </button> </td> </tr> <tr><td>{1}4</button></td> <td>{1}5</button></td> <td>{1}6</button></td> <td>{2}*</button></td> </tr> <tr><td>{1}1</button></td> <td>{1}2</button></td> <td>{1}3</button></td> <td>{2}-</button></td> </tr> <tr><td>{1}0</button></td> <td></td> <td>{1}.</button></td> <td>{2}+</button></td> <td> <button class='{3}' onclick='javascript:g_{0}.OnEqual();'> = </button> </td> </tr> </table>", UniqueID, _strNumButton, _strOpButton, sc_strStyleClass, _intCalcValue); writer.Write(strHtml); writer.Write("<INPUT type='submit' name='" + this.UniqueID + "' value='Save'></INPUT>"); writer.Write("<H3 id='" + UniqueID + "_savedVal'>" + _strSavedValue + "</H3>"); } // End Render } }
Listing 5: calculator.cs
<%@ Page %> <%@ Register <spotu:Calculator <hr> <spotu:Calculator </form> </body> </html>
Listing 6: calculator.aspx
function Calc(dispId) { this.intCurrentVal = 0; this.intLastNum = 0; this._op = ""; this.bEqual = false; this.displayId = dispId; this.EnterNumber = function(num) { if (this.bEqual) this.OnClear() if (this.intLastNum != 0) this.intLastNum += num; else this.intLastNum = num; document.all(this.displayId).value = this.intLastNum; } this.ComputeValue = function() { switch (this._op) { case '+': this.intCurrentVal = Number(this.intCurrentVal) + Number(this.intLastNum); break; case '-': this.intCurrentVal -= this.intLastNum; break; case '*': this.intCurrentVal *= this.intLastNum; break; case '/': this.intCurrentVal /= this.intLastNum; break; default: this.intCurrentVal = this.intLastNum; } document.all(this.displayId).value = this.intCurrentVal; } this.OnOperator = function(op) { if (!this.bEqual) this.ComputeValue(); this.bEqual = false; this.intLastNum = 0; this._op = op; } this.OnEqual = function() { this.ComputeValue(); this.bEqual = true; } this.OnClear = function() { this._op = ""; this.intCurrentVal = 0; this.intLastNum = 0; this.bEqual = false; document.all(this.displayId).value = this.intCurrentVal; } }
Listing 7: JavaScript source file for calculator
.calcButton { width=25; }
Figure 8: Stylesheet for calculator buttons
Examining the Code
One item to note is that the reference to the stylesheet that defines the style for the calculator buttons is located in the OnInit method along with the script block registration. Registering blocks of client-side code is not limited to "script" alone. The stylesheet here is external, allowing the designer the ability to modify the look and feel of the buttons by modifying the .css file. Another approach to allowing the page designer to change the look and feel of the calculator would be to implement custom properties, or better yet, custom properties with sub-properties to group them together (example: Font-Style, Font-Size, and so forth). This approach seems somewhat limiting in that the designer then can only change the properties you have exposed. With stylesheets, the designer has all the options available to him/her that would be there if a standard HTML element was being used, options that would otherwise be unavailable because he/she does not have direct access to the HTML elements your custom control produces and would not be able to apply a class or style to them.
There is one block of script that is written out when the control is rendered instead of beign included in the .js file. This allows multiple instances of the calculator control to be used in the same page. The UniqueID property inherited from the Control class is used to differentiate the controls from each other. The UniqueID property is a unique identifier that identifies an instance of a control within a page.
The locations of the stylesheet and the external script file default to an /includes directory located at the virtual application root. However, there are two custom properties provided that allow the designer to override where those file are located.
By using the UniqueID for the control as the name for the submit button, we make sure that the LoadPostData method for our control only gets called when the 'Save' button for that control is clicked. If we had named the text box with the UniqueID for the control, we would end up saving the calculated number for all the controls on the page, regardless of how the submit to the server was done. This example is a little contrived and if you are really serious about reducing server load, you could alter the 'Save' button so that, instead of posting the form back to the server, it does a Web Services call.
Conclusion
Using custom controls to generate client-side script can have tremendous benefits. The custom control will look and behave similarly to any other control written with ASP.NET, making it easy to reuse and shielding the page designer from needing to know the details of how the code works. By using client-side scripting to create the dynamic behaviors, you can greatly increase the responsiveness of the individual pages and the overall performance of your web site by significantly decreasing the number of calls that are made to the server. Using external files for your script has both positives and negatives. The pros include taking advantage of browser caching and easy access for customizability. The cons include a more complex deployment both in the production environment as well as the design time environment.

Right, I meant that when the javascript makes an AJAX request (with the
cocoon-ajax header set), it checks the response for the existence of any
bu:replace elements, and if none are present it allows the HTML to
submit the form normally so the flow can continue. But if you were to
manually insert a bu:replace in the template, that would mean that the
response to each AJAX request would always contain that bu:replace, so
you'd never get the empty document.
Anyway, getting off-topic.

ASP.NET MVC ModelBinder: Use ModelBinders For QueryStrings
ModelBinding is popular for sending form data back to the server, but did you know that you can use ModelBinders with GETS as well as POSTS? This quick tip will show you how to pass QueryString parameters to the server using a Model.
ModelBinders were introduced as a way to send your data from the page over to the server. When you post your data back to the server from a form, your POST method in your controller can use either a ViewModel or a FormCollection parameter.
But did you know that when you access a page using a GET instead of a POST, you can pass QueryStrings, cookies, or any other Request parameters into a Model and use them in your pages.
Let's go to our old friend the FaqController from our past post.
Paging Mr. FAQ
Let's have our FaqController Index page accept paging parameters.
We need to make our paging model so we'll create the following class:
Models\PagingModel.cs
namespace ModelBindingExample.Models { public class PagingModel { public int PageIndex { get; set; } public int PageSize { get; set; } } }
Now we need to tell MVC that our model attaches to a ModelBinder class. Makes sense, right? :-)
For each model you want to bind, you need the ModelBinderAttribute to point your model to your ModelBinder class as shown below.
using System.Web.Mvc; using ModelBindingExample.ModelBinders; namespace ModelBindingExample.Models { [ModelBinder(typeof(PagingBinder))] public class PagingModel { public int PageIndex { get; set; } public int PageSize { get; set; } } }
Now let's work on our PagingBinder ModelBinder class. You can either inherit from the DefaultModelBinder class or use the IModelBinder with the BindModel method.
When you use the DefaultModelBinder method, you need to override the BindModel method. }; } } }
See near the top of the method where we use QueryString? We can easily replace that with any type of data in the Request object. We could use Cookies, Form Data, UserAgent, IPAddresses, or even Referral Urls. Whatever we want to grab, we can store in a model.
Now that we have our modelbinder, we can use the model in our FaqController Index page.
Controllers\FaqController.cs
// GET: FAQ public ActionResult Index(PagingModel model) { return View(_factory.GetViewModel<FaqController, FaqViewModel>(this)); }
It's all set up as a parameter in our Index page/method. When we run it for the first time using the following URL:
we see our model will have the default values: Page = 0 and Size = 20.
But when we use the following URL
we see the values passed from the QueryString.
Conclusion
The ModelBinders are perfect for gathering specific data from HTTP Requests and passing them into your controllers in a neat, tidy little package instead of having HttpContext.Currents all over the place. When you receive this nice model in your controllers, it's kind of like Christmas!
Ok, maybe not Christmas, but it makes your code a lot cleaner and testable in the long run.
I hope this tip helps you out.
UPDATE: By request, I added a quick unit test for this Model Binder with a post called Unit Testing ASP.NET MVC Model Binders. | https://www.danylkoweb.com/Blog/aspnet-mvc-modelbinder-use-modelbinders-for-querystrings-QC | CC-MAIN-2017-04 | refinedweb | 525 | 64.61 |
Groovier Box Scores
August 29, 2007 Leave a comment
I made a couple more fixes to my box scores script to make it a bit groovier. First is a trivial one, but it’s much more in the Groovy idiom than in Java.
I replaced
def cal = Calendar.getInstance()
with
def cal = Calendar.instance
Groovy automatically uses the getter if you access a property of a class, as long as the property itself is private. Properties in Groovy are private by default, too, which is much more intuitive than Java’s “package-private” access. Of course, methods are public by default.
The other modification I made had to do with the fact that I was concerned about reading the remote XML file line by line. I thought it might be more appropriate to read the entire file into a local variable and then parse the file.
To do that, I found that the URL class had a
getText() method (or, more in the Groovy spirit, a
text property). That meant I could read the entire page by writing
def gamePage = new URL(url).text
Now the matching can be done all at once via
def m = gamePage =~ pattern
which results in a collection of matches. The only complication is that the pattern I’m searching for (
/${day}_(\w*)mlb_(\w*)mlb_(\d) /) appears twice in each line, once as the text value of the <a> tag and once as it’s
href attribute. I figured the easiest way to deal with that was to use
eachWithIndex and only worry about the even-numbered matches:
def m = gamePage =~ pattern if (m) { (0..<m.count).eachWithIndex { line, i -> if (i % 2) { away = m[line][1] home = m[line][2] num = m[line][3]
etc. The rest is essentially the same.
A good source for figuring out the Groovy way to do things is the PLEAC Groovy page. It rocks.

In Z3Py, how can I check if equation for given constraints have only one solution?
If more than one solution, how can I enumerate them?
You can do that by adding a new constraint that blocks the model returned by Z3.
For example, suppose that in the model returned by Z3 we have that
x = 0 and
y = 1. Then, we can block this model by adding the constraint
Or(x != 0, y != 1).
The following script does the trick.
You can try it online at:
Note that the following script has a couple of limitations. The input formula cannot include uninterpreted functions, arrays or uninterpreted sorts.
from z3 import * # Return the first "M" models of formula list of formulas F def get_models(F, M): result = [] s = Solver() s.add(F) while len(result) < M and s.check() == sat: m = s.model() result.append(m) # Create a new constraint the blocks the current model block = [] for d in m: # d is a declaration if d.arity() > 0: raise Z3Exception("uninterpreted functions are not supported") # create a constant from declaration c = d() if is_array(c) or c.sort().kind() == Z3_UNINTERPRETED_SORT: raise Z3Exception("arrays and uninterpreted sorts are not supported") block.append(c != m[d]) s.add(Or(block)) return result # Return True if F has exactly one model. def exactly_one_model(F): return len(get_models(F, 2)) == 1 x, y = Ints('x y') s = Solver() F = [x >= 0, x <= 1, y >= 0, y <= 2, y == 2*x] print get_models(F, 10) print exactly_one_model(F) print exactly_one_model([x >= 0, x <= 1, y >= 0, y <= 2, 2*y == x]) # Demonstrate unsupported features try: a = Array('a', IntSort(), IntSort()) b = Array('b', IntSort(), IntSort()) print get_models(a==b, 10) except Z3Exception as ex: print "Error: ", ex try: f = Function('f', IntSort(), IntSort()) print get_models(f(x) == x, 10) except Z3Exception as ex: print "Error: ", ex | https://codedump.io/share/lpfwNYzIn5c4/1/z3py-checking-all-solutions-for-equation | CC-MAIN-2018-13 | refinedweb | 310 | 62.58 |

A Prometheus exporter for Buildbot
Project description
buildbot-prometheus is a Python package that provides a Prometheus metrics exporter for buildbot.
This package is build for Buildbot version 0.9.
Installation
$ pip install buildbot_prometheus
Then add the following to your buildbot master.cfg file and restart the master.
from buildbot_prometheus import Prometheus c['services'].append(Prometheus(port=9101))
The buildbot master should now be exposing metrics to Prometheus. An example of the metrics provided by the Buildbot exporter is shown below by using curl to fetch the metrics:
$101']
Prometheus will then automatically associate a job label of buildbot with metrics from this exporter. Prometheus will also automatically associate an instance label (e.g. ‘localhost:9101’) too.
All metrics exposed by this exporter are prefixed with the buildbot_ string as a namespace strategy to isolate them from other Prometheus exporters which. | https://pypi.org/project/buildbot-prometheus/16.9.1/ | CC-MAIN-2022-33 | refinedweb | 141 | 56.66 |
Compiling OpenCV 2.4.5 with VS 2013 RC
Has anyone had any luck compiling openCV with VS 2013 RC? I have tried and get a bunch of "min doesn't belong to namespace std" "max doesn't belong to namespace std" in the IlmImf module, and opencv_features2d doesn't compile with the following error:

Since the latest CMake UI doesn't yet support building with 2013 (at least from the UI and I'm a noob), my process was configuring CMake for 2012, and then opening the generated solution with 2013 and upgrading the compiler to vc12.
I was able to get past the min/max errors by adding header includes for <algorithm> in the 'offending' files, but I am stumped by the full error I posted above.

Not while I'm around
Nothing's gonna harm you
No sir, not while I'm around
Concurnas, like most modern programming languages, has support within its type system for
null, this is useful but comes with one specific danger... In conventional programming languages supporting
null, since any object reference can be of type
null, then there is the potential for error if a field access or method invocation is attempted on that null instance. In Java this manifests itself via the dreaded and ubiquitous
NullPointerException. Given that any object can be null, at any point of execution, this error can occur anywhere. Thus, in order to write strictly safe code one is forced to validate one's object references as not being null on a persistent basis to be really sure that this potential for error is eradicated. This time consuming and labour intensive process is often either skipped entirely or only partially completed in most projects. Leading for the potential for error. In fact this problem is considered so severe that it's often referred to as the Billion Dollar Mistake.
So why not remove
null from the type system entirely? Well, it turns out that for some algorithms having null is incredibly useful for representing uninitialized state. So we need to keep
null. But we can manage its negative aspects.
Concurnas, like other modern programming languages such as Kotlin and Swift, makes working with
null easy and safe by incorporating nullability a part of the type system, and by providing a range of null safety operators to assist in those instances where null is a desired object state. This allows us to write safe code in Concurnas which is largely free of
NullPointerException exceptions.
Type system nullability?
All non-primitive types in Concurnas are non-nullable at the point of declaration by default. Thus, attempting to assign a null value to a variable having a non-nullable type (or anywhere else where a non-nullable type is expected, for instance in a method argument etc) will result in a compile time error:
aVariable String = "a String" aVariable = null//this is a compile time error!
If one wishes for a variable to be able to hold a value of null, a nullable type must be declared, this can be achieved for a non-primitive type by appending a
?to the end of the type declaration. As per our previous example:
nullableVar String? = "a String"//nullableVar can hold a null value nullableVar = null//this is acceptable
With nullability as part of the type system we are able to write code such as the following safe in the knowledge that there is no possibility for a
NullPointerException exception to be thrown:
len = aVariable.length()
Attempting the same method call on
nullableVar results in a compile time error, as
nullableVar might be null:
len = nullableVar.length()//compile time error!
But of course not all instances of
nullableVar are null (otherwise there is no value to the code above), so how can we call the
length method? Lucky for us Concurnas has some clever logic to support working with nullable types and a a number of useful operators...
Smart null checking?
If a nullable variable is checked for nullability within a branching logic block, i.e. an if statement, then the fact that it has been established as being not null will be incorporated to any usage of said variable within the body of the if statement. So the following is valid code:
res = if(nullableVar <> null){ nullableVar.length()//we've already established that nullableVar is not null }else{ -1 }
This logic is reasonably comprehensive and can cater for complex cases such as the below, where we establish that a lambda is null in one if statement branch, and so can conclude that is must be non-null within another:
alambda ((int) int)? = def (a int) => a+10 res = if(alambda == null){ 0 }else{//we've established that alambda is not null alambda(1) }
This logic applies on an incorporated running basis within the if test, thus the following code is valid:
res = if(nullableVar <> null and nullableVar.length() > 2){ "ok" }else{ "fail" }
Furthermore, in cases where a nullable variable is assigned a non-nullable value, we know with certainty that said variable is now not nullable, Concurnas is able to make use of this information thus enabling the following code to be valid:
nullable String? = "not null" //... potentially other code... ok = nullable.length() //ok as we know at this point nullable isn't nullable
This logic is applied to branching control flow:
a=2; b=10 nullable String? = null if(a > b){ nullable = "ok" }else{ nullable = "also ok" } ok = nullable.length() //ok as we know at this point nullable isn't nullable
This inference logic extends to class fields with the caveat that calls to methods after the determination of non nullability will invalidate that inference (since it's possible such a method call may set our field in question to null). Thus the following holds:
class MyClass{ aString String? def foo(){ aString = null } def inferNonNull(){ aString = "ok" len = aString.length() //ok aString is not nullable foo()//foo may set aString to null len = aString.length() //error aString might be nullable } }
This logic does not apply to shared nullable variables since they can be set to null by any isolate having access to them.
Safe calls?
The safe call dot operator,
?.allows us to execute the method or field access on the right hand side of a dot for a nullable entity if it is not null. If it is null, then null is returned. This the type returned from any call of this nature will always be nullable.
nullableVar String? = "a String" len = nullableVar?.length() //len is of type Integer? (nullable Integer)
The safe call dot operator may only be applied to nullable entities, applying it to a non-nullable type results in a compilation error:
normalString String = "a String" len = normalString?.length() //compilaton error
Array reference safe calls ?
Safe calls can be applied to array reference calls by inserting a
?between the expression and array reference brackets
[]as follows:
maybeNull int[]? = [1 2 3 4] if condition() else null //maybe null got = maybeNull?[0] //got is of type Integer? "" + got
Chained safe calls?
Safe calls can be chained together, this is quite a common usage pattern:
enum Color{BLUE, GREEN, RED} class Child(-favColour Color) class Parent(-children Child...) parent Parent? = Parent(Child(Color.GREEN), Child(Color.RED)) firstChildColor = parent?.children?[0]?.favColour //chained safe calls
Elvis operator?
The Elvis operator1,
null. The difference with the Elvis operator is that when
null is found, the expression on the right hand side is evaluated and returned:
?:in Concurnas serves a similar purpose to the safe dot operator above in that it allows us to react appropriately to the case where the expression on the left hand side of the operator resolves to
nullableVar String? = null len int = (nullableVar?: "").length()
No null assertion?
The final option for working with nullable types in Concurnas is the no null assertion operator,
NullPointerException if
null is found on the left hand side, otherwise it will return the value (which is guaranteed to be not nullable) of the left hand side. For example:
??. This simply will throw a
nullableString String? = "value" //... notNull String = nullableString?? //throws a NullPointerException if nullableString is null
The operator may be used on its own in order to test for nullness without returning a value:
nullableString String? = "value" //... nullableString?? //throws a NullPointerException if nullableString is null
The no null assertion, like many other operators, may be used preceding a dot operator:
nullableString String? = "value" //... length int = nullableString??.length() //throws a NullPointerException if nullableString is null
Nullable generics?
When it comes to generic types, at the point of declaration by default the are non-nullable, that is to say, the default upper bound of a generic type declaration is
Object - which is not nullable. i.e. Below the
X generic types of our
TakesGeneric1 and
TakesGeneric2 classes are the same:
class TakesGeneric1<X> class TakesGeneric2<X Object> //Object is non-nullable
Since we have declared
X above as being non-nullable the following code is not compilable:
inst = TakesGeneric1<String?>() //compile time error
We could however redefine
TakesGeneric1 in order to achieve this:
class TakesGeneric1<X?> inst = TakesGeneric1<String?>() //this is ok
Classes having non-nullable generic types may still define nullable instances of those generic types as follows:
class TakesGeneric1<X>{ ~x X? } inst = TakesGeneric1<String>() inst.x = null //this is ok
Class field initialization?
Class fields if not initialized at point of declaration or via the constructor invocation chain will default to null. Class fields like this must be declared as being nullable otherwise they will be flagged up as an error at compilation time. For example:
class UninitNonNullables<X>{ aString String //initially set to null, but type not nullable - hence error! anArray int[] //initially set to null, but type not nullable - hence error! }
This can be solved by either declaring the variables as being of a nullable type or initializing them:
class UninitNonNullables<X>(anArray int[]){ //initialized in default constructor aString String? //nullable }
Using non-Concurnas types?
Code written outside of Concurnas, for instance in Java, may not have any null safety. As such, by default Concurnas is somewhat conservative when it comes to invoking methods originating from languages other than Concurnas. Though this does not come at a sacrifice to what code can be used, it does come with some caveats.
Essentially, unless otherwise annotated (see Annotating non-Concurnas code below), the methods of non-Concurnas types are assumed to consume and return values of unknown nullability. That is to say, they are assumed to be nullable but can be used as if they were both nullable and non-nullable. For example, a list:
alist = new list<String>() //generic param of java.util.ArrayList declared as a non-nullable type alist.add('inst') alist.add(null) //this is ok res1 = alist.get(0) //res1 is of nullable type: String? res2 String = alist.get(0)
The above would not be possible if the generic parameter of
java.util.ArrayList were to be known as either nullable or non-nullable - but it's unknown in this case. Let's look at what this causes in detail:
alist.add(null)- it is acceptable for null to be passed for a type of unknown nullability.
res1 = alist.get(0)-
res1will be inferred to be a nullable type.
res2 String = alist.get(0)- The value resulting from execution of the
getmethod call will be checked to ensure that it is not null before being assigned to
res2which has been declared as being non-nullable. This helps avoid "null pollution" - i.e. a
nullvalue being inadvertently assigned to a non-nullable variable.
In the above code where Concurnas attempts to avoid "null pollution" - if an unknown nullability type resolves to a null value and is set to a non-nullable variable (or say passed as an argument to a method expecting a non-null parameter) then this will result in a
NullPointerException. If the
alist variable were to be created with a nullable generic type:
alist = new list<String?>() then this logic would not be required, though of course we'd be unable to assign the return value of
alist.get(0) to the non-nullable variable:
res2 String. Throwing a
NullPointerException in order to avoid "null pollution" is not desirable, but necessary - and is a beneficial approach where the alternative is permitting "null pollution" because at least the
NullPointerException is thrown at the point of assignment/usage.
Annotating non-Concurnas code?
non-Concurnas code may be decorated with the
@com.concurnas.lang.NoNull annotation in order to indicate a type is not nullable. Types may also be declared as being explicitly nullable. Here is an example of this in action for some Java code:
import com.concurnas.lang.NoNull; import com.concurnas.lang.NoNull.When; import java.util.List; public static @NoNull List<@NoNull String> addToList(@NoNull List<@NoNull String> addTo, @NoNull String item ){ addTo.add(item); return addTo; } public static @NoNull(when = When.NEVER) List<@NoNull(when = When.NEVER) String> addToListNULL(@NoNull(when = When.NEVER) List<@NoNull(when = When.NEVER) String> addTo, @NoNull(when = When.NEVER) String item ){ addTo.add(item); return addTo; }
Above, for the
addToList method the following elements are tagged as non-null:
The return type:
java.util.List
The generic type qualification of the return type:
String
The first input argument of type:
java.util.List
The generic type qualification of the first input argument:
String
The second input argument of type:
java.util.List
The same applies for the
addToListNULL except all the elements above are tagged as being nullable.
Nullable wrapper?
Sometimes when working with objects having generic type parameters, it is not possible to qualify those parameters in a nullable manner, for instance with refs. This presents a problem if we wish to store a nullable type within such a container object. Concurnas provides the
com.concurnas.lang.nullable.Nullable class, auto imported as
Nullable to wrap around such as nullable type:
nullableinst = new Nullable<String?>(): nullableinst.set("ok") maybenull String? = nullableinst.get()
Nullable method references?
Method reference types can be declared nullable by nesting their declaration within parenthesis and affixing a
?as per normal. For example:
nullLambda ((int) int)? //nullable method reference
Where can NullPointerException's still occur?
There are some limited circumstances in which
NullPointerException may still occur:
When using non-Concurnas types or calling non-Concurnas code. Covered above.
When using the no null assertion. Covered above.
Values from non-Concurnas code. Concurnas attempts to avoid "null pollution" - as such it's possible for a
NullPointerExceptionexception to be thrown from checking that the return value of a unknown nullability type is non-null. This "null pollution" avoidance is not applied to the individual values of arrays as it would not be efficient to check every array in this manner. As such non-primitive arrays and n+1 dimensional arrays provided by non-Concurnas code should be used with care and attention to the possibility of null values being present within them.
When using non-Concurnas code. Concurnas has no control over code authored in other languages, so they may throw a
NullPointerException.

Hints for Creating and Installing UNIX Software
Introduction
Generating and installing software on the UNIX systems should be done in a similar, consistent fashion. This allows for ease of maintenance and upgrades, broader support between software staff members, and higher levels of security. This document will describe the process of introducing a new software package to the UNIX environment, starting from downloading the source code to the announcement to the mail list.
Building the application
Each section listed below describes the basic steps. Each step will have a full description of the process. But as each package is different, each step should be considered to be only a guideline. Adjust each step, as needed, when software packages have special needs.
To show an example during each step of the process, we will use the application “pcre”. “pcre” (Perl-compatible regular expressions) is a package that is fairly simple to download, compile and install. Compiling and installing will usually produce a few platform dependent executable programs, some include files, some libraries, some manual pages and some platform independent shared files. This example will create the package for Red Hat Enterprise Linux 5.
Preparing the software
First we need to find where the software source code resides, and what is the current stable version.
For the software application pcre, we need to find the source repository for the software. Usually a software has a web site of its own, and in this case, the web site is PCRE - Perl Compatible Regular Expressions.
Also, usually, there will be previous versions of the software in the /usr/src/local directory that include a “SRC” file. Use this file to store the path to the software download so others will have a clue where it was downloaded previously.
After checking the web site for pcre, the current version of the software is at version “7.8”.
Creating the source directory
Once a software application is identified, find a place in the source code directory to store the source code, any related support files and building scripts. Place all of the source code in the directory /usr/src/local and name the source code directory package-version.
For example, setting up the product pcre version 7.8, create a directory and set the modes for general ECN staff access:
iceberg$ cd /usr/src/local iceberg$ mkdir pcre-7.8 iceberg$ cd pcre-7.8 iceberg$ chmod 775 . iceberg$ chgrp ecnstaff . iceberg$ chmod g+s . iceberg$
Downloading the source code
Download the source into the source code directory. If a PGP signature is available for verifying the source code against tampering, be sure to download that file too. Next, verify the source code file with the signature file.
iceberg$ gpg --verify pcre-7.8.tar.gz.sig pcre-7.8.tar.gz gpg: Signature made Fri 05 Sep 2008 12:41:58 PM EDT using RSA key ID FB0F43D8 gpg: Good signature from "Philip Hazel <ph10@hermes.cam.ac.uk>" gpg: aka "Philip Hazel <ph10@cam.ac.uk>" gpg: aka "Philip Hazel <ph10@cus.cam.ac.uk>" iceberg$
Also, save the download location for the source code into a file named SRC. This will help with getting newer versions of the source code in the future.
iceberg$ cat >SRC iceberg$
Finally, make sure all the source files are writable by the ecnstaff group.
iceberg$ chmod g+w * iceberg$ ls -l total 1154 -rw-rw-r-- 1 cs ecnstaff 1168513 Jan 9 09:12 pcre-7.8.tar.gz -rw-rw-r-- 1 cs ecnstaff 287 Jan 9 09:12 pcre-7.8.tar.gz.sig -rw-rw-r-- 1 cs ecnstaff 55 Jan 9 09:17 SRC iceberg$
Picking the installation path
When the final package is installed, it will first be installed in the /opt directory. So for this example, the /opt directory for pcre will be:
/opt/pcre/7.8
Creating the installation directory
During the installation process, the files will be deposited into the /opt directory. We need to create the directory structure ahead of time so the installation process will complete without getting permission errors.
iceberg# cd /opt iceberg# mkdir pcre iceberg# cd pcre iceberg# mkdir 7.8 iceberg# cd 7.8 iceberg#
Next, temporarily set the owner of the directory so you may write to the files as a non-privileged user.
iceberg# chown cs:ecnstaff . iceberg#
Creating a build script
Create a script that will build the source code into the final program. It will be the build script that will hold all of the knowledge on how the executable is built and what kind of pain is needed to build new versions of the executable in the future.
The build script has four sections:
- Sets up the build environment: stopping on errors, setting the umask, setting the PATH variable
- Removed the old version and extracts out a new version
- Patches and configures the source code
- Builds the source code into an executable
The name of the build script will be BUILD, BUILD-platform, or BUILD-platform-bits, depending on the need. If the build script will need to build differently between Solaris and Red Hat Enterprise Linux, create two scripts, one for each platform. If the build script will need to build 32-bit and 64-bit version differently, include the bit count.
Some example script names are:
- BUILD - (builds anywhere)
- BUILD-SOLARIS - (builds on Solaris)
- BUILD-LINUX - (builds on Linux)
- BUILD-LINUX-64 - (builds a 64-bit version on Linux)
We will tend to build only the 32-bit version of software. Usually this works, but one example that does not work is when the application links against libraries when only the 64-bit library exists and the 32-bit version of the same library does not. In that case, build both 32-bit and 64-bit versions of the application, and install each on their corresponding host.
This script will be called BUILD.
Note: the script will create the programs so that the final installation will be in the /opt directory, along with the package name and version number.
In this example, here is the build script.
#!/bin/sh # Set the build environment set -e umask 002 PATH=/usr/local/bin:/usr/opt/bin:/usr/bin:/bin export PATH # Remove old source and extract fresh copy rm -rf pcre-7.8 tar xfz pcre-7.8.tar.gz cd pcre-7.8 # Patch and configure ./configure \ --prefix=/opt/pcre/7.8 # Build make
Note: This method of extracting out a fresh copy of the source code is prone to disaster if more than once instance of the build script is running on different platforms. Good advice is to run only one build a time.
Building the application
Build the source code directory. Cross your fingers.
iceberg$ ./BUILD ... mv -f .deps/pcre_stringpiece_unittest.Tpo .deps/pcre_stringpiece_unittest.Po /bin/sh ./libtool --tag=CXX --mode=link g++ -O2 -o pcre_stringpiece_uni ttest pcre_stringpiece_unittest.o libpcrecpp.la g++ -O2 -o .libs/pcre_stringpiece_unittest pcre_stringpiece_unittest.o ./.l ibs/libpcrecpp.so /usr/src/local/pcre-7.8/pcre-7.8/.libs/libpcre.so -Wl,--r path -Wl,/opt/pcre/7.8/lib creating pcre_stringpiece_unittest make[1]: Leaving directory `/system/src/local/pcre-7.8/pcre-7.8' iceberg$
Installing the application
Once the build is complete and seems to be okay, install the application into the /opt directory. By installing the programs into the /opt directory, using your own non-privileged account, keeps the installation from scribbling all over the system disk in case of errors or bad code.
Create an installation script INSTALL like the build script. If there will be special installation commands depending on the platform or number of bits, use a naming convention like the BUILD script name (see example script names above).
#!/bin/sh # Set the environment set -e umask 002 PATH=/usr/local/bin:/usr/opt/bin:/usr/bin:/bin export PATH # Set the build directory cd pcre-7.8 # Install make install
Install the application. Cross your fingers again.
iceberg$ ./INSTALL ... /usr/bin/install -c -m 644 'libpcre.pc' '/opt/pcre/7.8/lib/pkgconfig/libpcr e.pc' /usr/bin/install -c -m 644 'libpcrecpp.pc' '/opt/pcre/7.8/lib/pkgconfig/lib pcrecpp.pc' make[1]: Leaving directory `/system/src/local/pcre-7.8/pcre-7.8' iceberg$
Setting the final modes
Once the code is in the /opt directory, reset the modes of the files and directories away from your own user-identifier. This set of commands will do the job.
iceberg# cd /opt/pcre/7.8 iceberg# find . -type d -exec chmod g-s '{}' ';' iceberg# find . -exec chmod go-rwx '{}' ';' iceberg# find . -type d -exec chmod 755 '{}' ';' iceberg# find . -type f -perm -400 -exec chmod go+r '{}' ';' iceberg# find . -type f -perm -100 -exec chmod go+x '{}' ';' iceberg# find . -exec chown bin:bin '{}' ';' iceberg#
Build the distribution package
Once the application is built into the /opt directory, the next step is to package the application for distribution to all hosts.
The application will be built into a platform package, rpm packages for Linux or pkg packages for Solaris, and stored into a package repository area. Instructions for installation will be placed into an igor controlled configuration file. The configuration file will update overnight, and each host will install the package. References for executables and libraries will be placed into commonly reference directories so users can use the new software.
The method to create an rpm Linux or pkg Solaris package is unified so that these installations will work for either platform.
Creating a packaging directory
The packaging directory is located at /usr/src/local/packages. There are (currently) two directories, one for Solaris 10 and one for Red Hat Enterprise Linux 5.2.
- sparc-sunos5.10 - (Solaris 10)
- x86-redhat_e5 - (Red Hat Enterprise Linux 5)
Enter the directory for the platform. Next, create a package directory for the application. Use the same method as used for creating the source code directory. In this case, create a directory for pcre with version number 7.8.
iceberg$ mkdir pcre-7.8 iceberg$ cd pcre-7.8 iceberg$ chmod 775 . iceberg$ chgrp ecnstaff . iceberg$ chmod g+s . iceberg$
Create the package script
Create a package creation script called PKGINFO.
The PKGINFO file will contain all the information necessary to create the package installation files (either type of rpm or pkg) that will install the application into /opt. Also, will create additional package files that will install all of the symbolic links pointing to the /opt directory from places like /usr/local, /usr/opt, /usr/old or /usr/new.
The big feature of the PKGINFO file is to selectively create the symbolic links in the application. Not all files in the application need to be placed into the /usr area. By allowing the PKGINFO to select the files by regular expression, we can control the set of symbolic links in a smart way that can adjust as new versions of the software are developed.
Other features include adding additional symbolic links to adjust the presentation to the user, and to build service scripts to support the application that will automatically install or remove as the application is updated.
For this example, we will create a straightforward package info file. The package info file has a required section, plus some optional sections.
In the required section is the package description:
- $pkg_package - Name of the application
- $pkg_version - Version of the application
- $pkg_instance - Instance number
- $pkg_dir - /opt directory path
- $pkg_comment - Description of package
Then one or more optional sections. Almost always used is:
- @pkg_build_in - Where to build the symbolic links
Next mostly used will be:
- @pkg_skip_links - Symbolic links to skip
- %pkg_add_links - Symbolic links to add
The following are used to add menu entries for the package:
- %menu_progs - Define menu entries and link them to program files
- @menu_tags - Define which ECN submenu(s) will contain the entries
Optional menu entry information:
- %menu_terminal - Use when a program runs in a text based environment (e.g. pine)
- %menu_icon - Define an icon to be displayed on the menu item
These will be used for more complex packages:
- $pkg_warning - Display a warning message
- %pkg_preinstall - Script to run before installing
- %pkg_postinstall - Script to run after installing
- %pkg_preremove - Script to run before removing
- %pkg_postremove - Script to run after removing
- $prelink - Define as non-zero for packages that replace system libraries
For the example package pcre, where is the completed PKGINFO file:
$pkg_package = 'pcre'; $pkg_version = '7.8'; $pkg_instance = 1; $pkg_dir = '/opt/pcre'; $pkg_comment = 'pcre - Perl-compatible regular expressions'; $prelink = 1; @pkg_build_in = ( '/usr/new', '/usr/local', '/usr/old' );
The pkg_instance variable describes the instance number of a package. Should a package need to be recompiled or updated, but the version number is the same, then we use the instance number to tell the host systems to update their package. The instance number starts at 1 and is incremented each time the package is re-made.
The @pkg_build_in variable describes the one or more places that the package will create symbolic links. It can have any of the four places for an application:
- /usr/new
- /usr/local
- /usr/opt
- /usr/old
Note: /usr/local and /usr/opt are mutually exclusive. Both /usr/local and /usr/opt produce the same reference to the “current” version of the package.
The typical life cycle of a package is:
/usr/new → /usr/local → /usr/old
/usr/new → /usr/opt → /usr/old
Because there are multiple packages, and the packages are split between the application installing into /opt and the symbolic links, we are able to create a method of moving the packages between /usr/new, /usr/opt and /usr/old without having to add or remove the application from /opt.
Since pcre replaces system libraries, $prelink is set to a non-zero value to add it to the prelink search list.
In the case of pcre, we can create all four packages, (/opt package plus the three symbolic link packages), then only install the /opt and /usr/local package at this time.
Create the packages
Once the package info file is ready, create the package scripts. Running the package command will create all the files that will build the final rpm or pkg files used by the installer. The set of files built by the package command will be different between Solaris and Linux.
Run the package command. Usually there is no output when successful. When complete, there will be a new directory. For Solaris, the new directory will be called pkg. For Linux, the new directory will either be i386 or x86_64 depending on the platform.
iceberg$ ../package iceberg$ ls i386 PKGINFO iceberg$
Go into the new directory. In the directory will be a script for the binary (/opt) package and one script for each of the places for the symbolic links. In additional, there may be some other files to support the scripts.
iceberg$ cd i386 iceberg$ ls local_rpmmk new_rpmmk old_rpmmk opt_rpmmk local.spec new.spec old.spec opt.spec iceberg$
Next, run each of the scripts. If successful, each script will produce an rpm or pkg file that will be used for installation.
Note: Solaris builds the result into a file ending in .tgz - Linux will end in .rpm.
iceberg$ ./opt_rpmmk Building target platforms: i386 Building for target i386 Processing files: ECNpcreb-7.8-1 Checking for unpackaged file(s): /usr/lib/rpm/check-files /tmp/pk18573/RPM Wrote: /tmp/pk18573/RPM/RPMS/i386/ECNpcreb-7.8-1.i386.rpm Command completed successfully iceberg$ ./local_rpmmk Building target platforms: i386 Building for target i386 Processing files: ECNpcrel-7.8-1 Checking for unpackaged file(s): /usr/lib/rpm/check-files /tmp/pk18600/RPM Wrote: /tmp/pk18600/RPM/RPMS/i386/ECNpcrel-7.8-1.i386.rpm Command completed successfully ... iceberg$
Adding the package to igor
One the package files are created, the package will need adding to the installation configuration file so each host will be able to download and install the new application. In order to add the lines needed to igor configuration file, there is a utility command called make-igor.
Go back one directory, to the one with the PKGINFO file, and run the command make-igor in the parent directory.
iceberg$ ../make-igor @@ @@ iceberg$
Note: The name of the package is based on the pattern starting with “ECN”, followed by the name of the package, followed by a single character identifier to indicate the package type.
The type identifiers are:
- The letter “b” is the /opt package,
- The letter “n” is the /usr/new package,
- The letter “l” is the /usr/local package,
- The letter “p” is the /usr/opt package,
- The letter “o” is the /usr/old package.
The next step is to add these lines to the package configuration file that is under igor control. Go to Harbor and edit one of the package configuration files.
- For Solaris, edit /usr/share/adm/config/os/SunOS/5.10/packages
- For Linux, edit /usr/share/adm/config/os/Linux/5.2/packages
Take the lines produced by the make-igor command and add them to the file. The packages are sorted in alphabetical order, so find an appropriate place. Once the lines are added to the file, we need to comment out the entries we won't use now but will use in the future. Because we're installing the symbolic link package in the /usr/local directory, we need to comment out the lines for the /usr/new and /usr/old packages. Once the editing is complete, it will look like
Copy packages to repository
In order to install an application, the package files need to be placed into the package repository directory /package/repository. Any host installing packages will go to the repository to download the files. The repository directory is replicated across multiple package servers so that the loaded is distributed more evenly.
In the package directory, go back one directory, the one with the directory pcre-7.8. In this directory, there is a command to copy the package files to the repository called make-links. Run the command. Since the files are copying to the main package server, Dock, the command may prompt for your password.
iceberg$ ./make-links find: ./intel_fc-10.1.008/x86_64-wrong: Permission denied find: ./intel_cc-10.1.008/x86_64-wrong: Permission denied Password: guess building file list ... done ./ ECNpcreb-7.8-1.i386.rpm ECNpcrel-7.8-1.i386.rpm ECNpcren-7.8-1.i386.rpm ECNpcreo-7.8-1.i386.rpm sent 681369 bytes received 114 bytes 104843.54 bytes/sec total size is 877617221 speedup is 1287.81 iceberg$
Note: It's not unusual to see some permission errors. So long as the package files were updated, it is okay to ignore the errors.
It is helpful to run the following command. It makes sure that if a deploy is started after you have updated the packages file in igor that it won't hang because the files aren't in a repository used by the host being deployed:
/home/pier/a/cs/bin/update-pkgs
Test install
We need to test that the installation will go correctly. The first step is to clear away the source development directory so that the package installation has a clean start. The source code was installed into the /opt/pcre directory. Either delete the directory (the preferred method) or move it to a new name. If moving to a new name, be sure to clean up the mess after the test install is complete.
iceberg# rm -rf /opt/pcre iceberg#
Next, copy the new packages configuration file from Harbor.
harbor# cd /usr/share/adm/config/os/Linux/5.2 harbor# rsync -av packages iceberg:`pwd` building file list ... done packages sent 25114 bytes received 42 bytes 50312.00 bytes/sec total size is 25017 speedup is 0.99 harbor#
Next, run the igor command to update the packages.
iceberg# igor packages INFO: Installing ECNpcreb version 7.8 revision 1 INFO: Installing ECNpcrel version 7.8 revision 1 iceberg#
If nothing complains, check to see if the build seems to have set files up in the right places. Is the /opt directory there? For “bin” commands, is the /usr/local/bin symbolic links there and pointing to the right place?
iceberg$ ls /opt/pcre/7.8 bin include lib share iceberg$ ls /opt/pcre/7.8/bin pcre-config pcregrep pcretest iceberg$ ls -l /usr/local/bin/pcregrep lrwxrwxrwx 1 root root 30 Jan 13 09:29 /usr/local/bin/pcregrep -> /opt/pcre /current/bin/pcregrep iceberg$
Announce
Now once you've tested the application and become satisfied that the application is ready to use, make an announcement on the syslog mailing list. Be sure to list the following information in the announcement text:
- When will the software be available - now or overnight?
- What is the application name and version?
- What platforms on which will the application install?
- What is the application?
- Why is the application installing - new or upgrade?
- Are there any additional notes about the application?
- What package files are affected by the announcement?
Here's a sample announcement text:
After tonight's distribution, pcre version 7.8 will install or upgrade on all Solaris 10 and Red Hat Enterprise Linux 5.2 hosts. "pcre" is the Perl Compatible Regular Expressions library and executables.
This installation will make the "pcre" package available on Red Hat Enterprise Linux - it was already available on Solaris 10. The Solaris 10 version is an upgrade to match the version on Red Hat Enterprise Linux.
Package additions:
ECNpcre version 7.8 revision 1 (Linux)
Package changes:
ECNpcre version 7.8 revision 1 (Solaris)
Done!
You're done! Simple, wasn't it?
Advanced topics
The previous section was for creating and distributing a package should the package following a simple method, and that the package pretty much works the first time. Not all packages are that simple. In the following sections are advanced packaging topics that might need reference should a package need to be re
made because or an error, need distributing immediately, or need special features - such as those with an initialization script.
Adding menu entries.
Menu entries will only be added to 'current' versions (built in /usr/opt or /usr/local), and
can be added by defining the following variables in PKGINFO:
%menu_progs
This is a hash that contains the string to be shown on the menu and the program to
be run when the menu item is chosen. The executable program can be designated
as either a relative name (relative to /opt/program/version), or as an absolute
path (path begins with '/').
Example:
%menu_progs = (
'Matlab' => 'ecn/matlab.wrapper',
'Matlab Ver. x.y' => '/opt/matlab/x.y/ecn/matlab.wrapper'
);
@menu_tags
This is an array of tags that determine which site menu(s) will contain the entries.
The tags are strings designating the site(s) (i.e. 'aae', 'abe', 'ie', etc.). The menu
entries will appear only in the listed site submenus. The submenus are chosen by
the host's igor SITE setting.
A special tag, 'all', will place the item in the 'ECN Applications' submenu on all hosts.
Menu items with site specific tags will appear in the '<site_name> Site Applications'
submenu (e.g. 'AAE Site Applications'). In general, you should not include a package
in both an individual site and 'all'.
%menu_terminal (Optional)
This designates whether or not a terminal window is required by the application. Some
command line style applications may be launched from the menu interface.
To designate that a terminal window is to be used, this should be set to 'True'. If it is
not defined, it will default to 'False' and no terminal window will be started.
This is a hash so that it can be designated per program.
Example:
%menu_terminal = (
'Pine' => 'True',
'Pico' => 'True'
);
%menu_icon (Optional)
This is used to define an icon to be displayed on the menu item. The value is the absolute
path to the icon file to be displayed. It will default to NULL and no icon will be displayed
if it is not defined. It is a hash so that it can be designated per program.
Example:
%menu_icon = (
'Kile' => '/opt/kile/2.0.3/share/icons/hicolor/16x16/apps/kile.png'
);
Removing packages by hand.
During the package development, if the package was installed but had some kind of error, the package may need to be removed from the system by hand. Errors may happen even if the source code builds and the installation script installs correctly, but the package itself create a problem such as a conflicting file between this package and a previously installed package.
The igor script will remove a package, but if development of the application is on-going, it is usually easier to remove the package by hand. Removing the package is done differently between Linux and Solaris, but the only difference is the command.
- To remove a Linux package, use the command rpm -e followed by each package name,
- To remove a Solaris package, use the command pkgrm followed by each package name.
Note: It is probably best to remove all the packages at once, and to remove the /opt package last.
An example package removal command is:
iceberg# rpm -e ECNpcrel ECNpcreb iceberg#
Re-running igor
Igor caches the list of packages that wants to install on a host. If you've removed the package by hand, igor won't reinstall the package without help - it thinks the packages are up-to-date. Once way to fix this is to remove the package configuration file stored by igor. This will force igor to evaluate all the packages again to make sure they are up-to-date.
iceberg# igor packages iceberg# rm /etc/packages.conf rm: remove regular file `/etc/packages.conf'? y iceberg# igor packages INFO: Installing ECNpcreb version 7.8 revision 1 INFO: Installing ECNpcrel version 7.8 revision 1 copy: WARNING: Igor controlled file disappeared since last run: /etc/packages.conf iceberg#
Replicating the repository to other package servers by hand
Should a newly create package need installing immediately, there will be a problem when a non-central-ECN host is requested to install the package.
The package repository is distributed across package disk servers. When the package was updated in the repository, the update only occurred on the main package disk server, Dock. Before pushing out a newly package application, update all of the repository mirrors.
One way to accomplish an update is to run the packages “rdist” command. Unfortunately, this command will update all of the package disk contents and will take much to long to complete. We need to update only the repository portion of the package &ldquob” disk.
In order to do a hand update of the repository from the package “b” disk, you'll need to get the list of package disk mirror hosts. On the server Dock, go to the directory /var/rdist/packages. At the top of the file dock is a macro for to package &ldquob” disk called PKGB_SERVERS. Same the list of host.
Next, create a distribution file. The file, call it my-pkg, should have the following commands, replacing the list of hosts with the PKGB_SERVERS macro.
( /export/package/b/Repository ) -> ( list of hosts ) install -R; except_pat(/RCS\$);
Next, run the following command to distribute the files:
/usr/local/etc/rdist -onumchkowner,numchkgroup -fmy-pkg
Once the repository directory is up-to-date on all package servers, continue with the package update to all hosts.
Deciding when to add or skip links.
Sometimes it is desirable to skip certain portions of the application files when creating links in the /usr/xxx directory. Reasons to skip some of the links may be:
- Reduce the number of links,
- Alter link paths,
- Remove unnecessary links that users won't need,
- Combine whole directory trees into one link,
- Remove conflicts between applications.
Some applications create huge number of files. Vendor applications, for example, are stored on the package disk, and we only need to create one command to refer the user to when they want to run the application.
An example, Abaqus, only needs one program installed into the bin to get things started. After that, the application refers to the package directory. If we let the package command create a link for each file, it would create over 18,000 links.
For Abaqus, we only need one executable. To accomplish this, the PKGINFO file needs to skip every file, then create one link to the start-up script. Also, in reference to “altering link paths”, The Abaqus executable is in the different place than the link itself.
To request that the package skip all links, we use the regular expression . (a single dot character) that matches all files. The package info file would have the following rule:
@pkg_skip_links = ( '.' );
Next, we need to add back a link to the executable. The package info file add links in the form “from” → “to”. For Abaqus, we need to have a bin command available called abaqus. But the link will point to a location in the /opt directory that is under a different path, called ecn/bin/abaqus. The package info file would have the following rule:
%pkg_add_links = ( 'bin/abaqus' => 'ecn/bin/abaqus' );
In the add links command, the source and destination are relative paths if the path does not begin with a / (slash character). If this application is installed into /usr/opt, then the link will be created as /usr/opt/bin/abaqus. Having a relative path will allow the packaging command to create absolute paths different between all the different version of the link packages.
Some packages may create conflicts if one package creates a file that is different than another package. If there are cases where a conflict will result, careful analysis will be needed to keep two packages from interfering with each other, or causing the package to fail to install. In these cases, it's usually possible to omit the conflicting file from one or more packages - sometimes all packages. Add skip link commands to the package info file as needed.
Another use of skipping and adding links is to combine whole directory trees. If an application creates a subdirectory in the directory structure that has a unique prefix, it may be possible to remove the subdirectory and make a single link.
An example is the application freetype. In the directory structure for /opt/freetype/2.1.10, there is a set of include files under the directory include/freetype2. On their own, they would create 86 links into the /usr/local/include/freetype2 directory. Because of the subdirectory that we placed under the include, we can skip then relink directory as one link. The package info file would look like this:
# Remove the directory from the set of links @pkg_skip_links = ( 'include/freetype2' ); # Add back a link to the directory %pkg_add_links = ( 'include/freetype2' => 'include/freetype2' );
Adding tags for special handling
Occasionally, conditions exist that require special handling of an installation. Some examples are package dependencies or unwanted interaction with other packages. RPM provides a mechanism for handling many of these with tags. Tags are added to the package's .spec file by using the %pkg_tags hash. The hash keys are comprised of the tag labels, while the values associated with the keys contain the value for that label.
As an example, to automatically handle a package that contains a version number in its package name, the following tag will automatically obsolete the previous package when the new package is installed. In this example, the package being built is 'Package124', and its previous version is named 'Package123'.
%pkg_tags = ( 'Obsoletes' => 'Package123' );
This will result in the following tag being added to Package124's .spec file:
Obsoletes: Package123
Any valid RPM tag can be specified in this manner.
System services
One of the most often use of advanced application packaging is the ability to create an application that has a system start/stop script. The start/stop script is placed in /etc/init.d and will be called when the system boots or shuts down. In order to use a start/stop script, several changes need to happen, such as adding the start/stop script to the package directory and installing/removing the script to the system when the package is installed/removed.
A start/stop script is an shell script that is called when the system starts or stops, or if the service needs to be restarted. The shell script is called with an argument to indicate if the service is starting (by calling the script with the argument start), or if the service is stopping (by calling the script with the argument stop), or restarting (by calling the script with the argument restart). start and stop commands are required - restart is optional but usually needed.
When package an application that uses a start/stop script, place the script in the package directory under the directory etc/rc. As an example, we'll use the “Condor” application. In the case of Condor, the start/stop script will be located in /opt/condor/version/etc/rc/condor.
Adding the start/stop script to the package directory structure is not enough. We need to install the start/stop script when the package is added to the system, and to uninstall the start/stop script when the package is removed from the system. We do that by adding installation and removal commands to the package info file.
There are two types of install and two types of remove script that can be called by the package. They can be before or after the package is installed or removed. In the case of adding a system service, we need to add the start/stop script to the system after the install (postinstall) and we need to remove the start/stop script to the system before the remove (preremove). We can accomplish these steps by creating a postinstall script and a preremove script.
The script we need to install the start/stop script into the system for Condor will look like this. The name of the script will be called postinstall.
Note: The postinstall and preremove scripts will be different between Linux and Solaris. This is an example script for Linux.
#!/bin/sh # # Condor installation script # # Name of service service=condor # Install service chkconfig --add $service
Also, the script we need to remove the start/stop script from the system for Condor will look like this. The name of the script will be called preremove.
#!/bin/sh # # Condor removal script # # Name of service service=condor # Stop service service $service stop # Disable service chkconfig $service off # Remove service chkconfig --del $service # Success exit 0
It is important to make the removal script exit with a zero status. If, for example, the service is not installed (for some reason) when we remove the package. We want the script to attempt to remove the service, but continue to run successfully if it does not remove.
Note: If any of the “preinstall”, “postinstall”, “preremove” or “postremove” scripts are set to be executables, then the package command package will run the script and use the output for making the package. If the scripts are not executable, then the scripts are used as-is. This allows the Solaris version of the postinstall file create a dynamic script.
Next, add all of the files and scripts to the package info file. This will tell the package command to add start/stop script as a link to the file, plus add the install/remove command scripts to the package so the system is updated. Each script will correspond to the symbolic link package that is set to build. For Condor, this is the set of commands.
%pkg_add_links = ( '/etc/rc.d/init.d/condor' => 'etc/rc/condor', ); %pkg_postinstall = ( '/usr/local' => './postinstall' ); %pkg_preremove = ( '/usr/local' => './preremove' );
Because the Solaris version is significantly different, here are the differences should we build Condor for Solaris.
The postinstall script looks like this, and is an executable script. Note how this script executes to build another script.
#!/bin/sh # Build postinstall script cat <<'XXX' #!/bin/sh # # Condor installation script # # Setup for temporary files XMLFILE=/tmp/condor-tcp.xml trap 'rm -f $XMLFILE' 0 1 2 15 # Add apache service cat >$XMLFILE <<'ZZZ' XXX # Process Internet service entry ../inet-svc # Part 2 cat <<'XXX' ZZZ /usr/sbin/svccfg import $XMLFILE XXX
The preremove script looks like this. This script is not executable - it is used as-is.
#!/bin/sh # # Condor removal script # # Disable service /usr/sbin/svcadm disable -s svc:/network/condor:default # Remove service /usr/sbin/svccfg delete svc:/network/condor # Success exit 0
And finally, the package info file is nearly the same as Linux. Only the location of the start/stop script is different with Solaris.
%pkg_add_links = ( 'lib/svc/method/condor' => 'etc/rc/condor' ); %pkg_postinstall = ( '/usr/local' => './postinstall' ); %pkg_preremove = ( '/usr/local' => './preremove' );
32-bit vs. 64 bit.
More often on Red Hat Enterprise Linux running in 64-bit mode, applications may need to be compiled twice. Once for 32-bit, and once for 64-bit. We can get away with running only the 32-bit version on both 32-bit and 64-bit machines so long as the application references shared libraries that fully exist on the 64-bit platform.
This is not always the case. When creating the 32-bit package and installing it on a 64-bit machine, check to make sure all of the application calls work. If a program references a 32-bit shared library that is not available on the 64-bit platform, it may be necessary to create two sets of packages - one set for 32-bit hosts and one set for 64-bit hosts.
Usually it is possible to create the packages with the same steps as above without changes, including the PKGINFO file. When it comes time to package an application with the information in the PKGINFO using the package command, the results will be stored in a new subdirectory called x86_64. Normal 32-bit applications will create the subdirectory i386. Be sure to pick the right subdirectory to enter before issuing the package building commands.
Adding the list of packages to igor will also need to have the package installation commands separated out by architecture. In the example of Condor, there are two sets of installation files, surrounded by igor @if statements. The command lines for Condor looks like this:
@@ @@ condor - High-throughput network computing environment @@ @if ARCH == "x86_64" install ECNcondorb 7.0.4 2 ECNcondorb-7.0.4-2.x86_64.rpm install ECNcondorl 7.0.4 2 ECNcondorl-7.0.4-2.x86_64.rpm @endif @if ARCH == "i386" install ECNcondorb 7.0.4 2 ECNcondorb-7.0.4-2.i386.rpm install ECNcondorl 7.0.4 2 ECNcondorl-7.0.4-2.i386.rpm @endif
Notice the architecture type in the RPM filename - they should match the @if/@endif command block.
Moving applications from new → local → old.
During semester breaks, it is customary to cycle new version of applications into the default path, and the older version into the old path. We can make this change easier if the entire lifecycle of package installation files are made ahead of time.
In the case of our pcre package, we can move the current version to an old version by adjusting the igor commands in the package configuration file. If we start with a set of package installation command lines
We only need to remove the /usr/local package of symbolic links and add in the /usr/old package. Change the script to this:
@@ @@ pcre - Perl-compatible regular expressions @@ install ECNpcreb 7.8 1 ECNpcreb-7.8-1.i386.rpm @@install ECNpcren 7.8 1 ECNpcren-7.8-1.i386.rpm uninstall ECNpcrel 7.8 1 ECNpcrel-7.8-1.i386.rpm install ECNpcreo 7.8 1 ECNpcreo-7.8-1.i386.rpm
The next time a system updates its packages, the binary package will not change, the /usr/local package will be removed , the the /usr/old package will install. We need to remove the /usr/local explicitly.
Updating a package
The igor script that installs and removes packages knows how to upgrade a package implicitly. That is, if a package of version x is installed, and the package configuration file says that version x+1 should be installed instead, the package x will be upgraded. This elevates the need to explicitly add uninstall commands. There is no harm in adding explicit uninstall commands if you want to make sure a package is removed.
Package name conflicts
Because of the way Solaris and Linux handles base package names, it is sometimes necessary to uniquely identify a package name by a version tag. Yuch!
An example of this problem is when multiple versions of a package is needed. For example, if we want to run pcre for both version 7.7 and 7.8, we would have to create a separate base name. We cannot have a package named ECNpcreb that creates the directory path /opt/pcre/7.7 at the same time we have a package named ECNpcreb that creates the directory path /opt/pcre/7.8. Unfortunately we have to name the base package separately. We can adjust the package name on the new version and merge it into the package configuration file along with the older version.
This example creates two different versions of pcre. The newer version 7.8 in /usr/local and the older version 7.7 in /usr/old. Since the older version is already named pcre we need to adjust the name of the newer version.
@@ @@ pcre - Perl-compatible regular expressions @@ install ECNpcreb 7.7 1 ECNpcreb-7.7-1.i386.rpm install ECNpcreo 7.7 1 ECNpcreo-7.8-1.i386.rpm install ECNpcre78b 7.8 1 ECNpcreb-7.8-1.i386.rpm install ECNpcre78l 7.8 1 ECNpcrel-7.8-1.i386.rpm

Hi I'll be showing you how to use a Raspbery Pi and an LED matrix to display some scrolling text.
Step 1: Gather Materials
- Raspberry Pi (I'll be using a 2)
- RGB Matrix HAT + RTC
- 32x32 LED Matrix
- Jumper wires
Tools
- Soldering Iron + Solder
Step 2: Solder HAT Together
There are three small pieces that come with the Matrix HAT kit, which should be soldered to the top of the HAT itself.
Step 3: Connect Everything Together
This step is pretty straight forward.
- You should first connect the HAT itself to the Pi, using the 20x8 header bridge.
- Then connect the data cable between the HAT and the LED matrix.
- After that, The matrix itself needs power, which can be supplied by plugging a power cable into the HAT or using a different connector to bypass the HAT.
After this, everything should be connected, and once you supply power to both the Pi and the matrix, you should be good to go!
Step 4: Setup Pi + Python
Connect your PI to a monitor or a laptop and ssh in.
Then you'll need to install Python with these commands:
sudo apt-get update
sudo apt-get install python-dev python-imaging
Then download the code for driving the matrices:
wget unzip master.zip
Now you'll need to cd into the directory you just unzipped, and build the driver
cd rpi-rgb-led-matrix-master/
make
Now you can run the test demo led-matrix with this command, where D is any number from 1-9
sudo ./led-matrix -D 4
In the next step, I'll be showing you how to write your own program!
Step 5: Programming the Matrix
Use the following code, replacing the message with whatever you want, along with the colors for each part.
import os
from PIL import ImageFont from PIL import Image from PIL import ImageDraw text = (("Raspberry Pi ", (255, 0, 0)), ("and ", (0, 255, 0)), ("Adafruit", (0, 0, 255))) font = ImageFont.truetype("/usr/share/fonts/truetype/freefont/FreeSans.ttf", 16) all_text = "" for text_color_pair in text: t = text_color_pair[0] all_text = all_text + t print(all_text) width, ignore = font.getsize(all_text) print(width) im = Image.new("RGB", (width + 30, 16), "black") draw = ImageDraw.Draw(im) x = 0; for text_color_pair in text: t = text_color_pair[0] c = text_color_pair[1] print("t=" + t + " " + str(c) + " " + str(x)) draw.text((x, 0), t, c, font=font) x = x + font.getsize(t)[0] im.save("test.ppm") os.system("./led-matrix 1 test.ppm") | http://www.instructables.com/id/Raspberry-Pi-LED-Scrolling-Text-Display/ | CC-MAIN-2017-17 | refinedweb | 416 | 60.45 |
I linked to it above, but here it is again in more or less final form (with domains changed):
import localforage from 'localforage' register(process.env.SERVICE_WORKER_FILE, { ready () { console.log('App is being served from cache by a service worker.') }, registered (registration) { // registration -> a ServiceWorkerRegistration instance console.log('Service worker has been registered.') // console.log('scope: ' + registration.scope) }, cached (registration) { // registration -> a ServiceWorkerRegistration instance console.log('Content has been cached for offline use.') }, updatefound (registration) { console.log('New content is available; please refresh.') /* eslint-disable no-extra-boolean-cast */ if (!!window.chrome) { // for chromium based) }) } }, updated (registration) { // registration -> a ServiceWorkerRegistration instance console.log('New content is available; please refresh.') if (!window.chrome) { // for non chromium) }) } }, offline () { console.log('No internet connection found. App is running in offline mode.') }, error (err) { console.error('Error during service worker registration:', err) } })
It seems that Quasar now supports this out of the box:
@danbars Quasar supports loading clientsClaim and skipWaiting directives into the SW file, but for a number of reasons this is not enough. Also, while on supported platforms it will update your PWA, it will do so silently. I needed a way to do all of the following:
- Control or initiate the update process
- Set my own versioning
- Notify users about updates
- Perform actions related to the update
- Work around platform and browser limitations and inconsistencies so that it works the same everywhere and without failure

Hi guys, I have a doubt, how does the browser know there is a new update? is the package-lock.json?
just changing this:
{
“name”: “app”,
“version”: “0.0.1”,
is enough to automatically update on android/desktop browsers/installed versions?
@zeppelinexpress when you build your project (for a PWA) there will be new cache signatures, which a PWA should read and then force an update. However, as mentioned above this is inconsistent across platforms and I have found it necessary to make my app check a version string that I set on the server and call the update mechanisms at that point which works everywhere. See the code examples above for what I use to make this work.
Rejoining this thread, because I’ve figured out a complete solution for a user controlled app refresh (similar to the pop-up in the Quasar documentation) that might be useful for others who have the same issue. It’s a combination of ideas taken from the Workbox Advanced Recipes () and an article by Doug Allrich. It uses the Workbox-Window plug-in from Google.
<template> <q-dialog <q-banner> A new version is available. <template v-slot:action> <q-btn </template> </q-banner> <q-dialog> </template> <script> import { Wokbox } from 'workbox-window' export default { data() { return { displayUpdatePrompt: false, workbox: null, } }, methods: { refreshApp() { this.workbox.addEventListener('controlling', () => { window.location.reload() }) this.workbox.messageSkipWaiting() } }, created() { if ('service-worker' in navigator) { this.workbox = new Workbox('/service-worker.js') this.workbox.addEventListener('waiting', (event) => { this.displayUpdatePrompt = true }) this.workbox.register() } } } </script>

For someone new to electronics, capacitive sensing can be really confusing. Even for someone who's been exploring capacitive sensing for a week, it's STILL really confusing. Luckily, you'll have this this handy guide to help you on your road to becoming a capacitive sensei. Here you'll find a bunch of guides, tips, tutorials and general information about this unstable and strange sensor technology.
Step 1: The Boring Stuff
Before we move on to the fun (but mostly frustrating) projects you can embark on with capacitive sensing, let's take a quick look at how it really works.
How does it work?
To understand how capacative sensors work, first you have to understand how a capacitor works.
A capacitor consists of 2 electrical conductive surfaces (also called electrodes), one is connected to the positive pole of the electrical circuit and the other is grounded. Between these surfaces there is a non-conductive layer wich is called a dielectric. The capacitor can be compared to a small battery. When sending a pulse to the capacitor, it quickly charges. When the signal goes to zero, the capacitor discharges. This creates a delay in the pulse due to the time it takes to charge and discharge the capacitor.
A capacative sensor works in the same way as a capacitor. The sensor itself is only a conductive surface and will start working as a capacitor by the proximity of any other conductive surface, for example by skin (as long as it has a relative negative charge).
When making a capacative sensor with Arduino you will have an output that transmits a pulse, and an input which receives the pulse and compares it to the transmitted pulse. When you you put your finger on or near the sensor it creates a delay in the pulse, and this delay is recalculated by the CapSense library and generates a value you can use for triggering etc.
Step 2: Stuff That Uses Capacitive Sensors
Step 3: Making Your First Capacitive Sensor
You could go off and buy a ready-made capacitive sensor from Adafruit or Sparkfun, but where's the challenge in that? Capacitive sensors are easy to make yourself with an Arduino board and some basic electronic components.
You will need:
1 x Arduino board. We used an Arduino Uno.
1 x Arduino USB cable.
1 x Breadboard. Not really necessary, but makes things a bit easier.
1 x Metal object, like a paperclip, copper plate or a piece of aluminium foil. This will be the connecter with which you interact with to send a signal to your Arduino.
Electric wires
A resistor. We have found that you should use at least 1 MOhm, but tried using up to 37,6 MOhm. The higher the resistance, the higher readings you will get. If you don't have big enough resistors, you can daisy-chain a bunch of them together.
Step 1: Download the CapSense library from Arduino. Extract the files to Documents/Arduino/libraries. Restart Arduino.
Step 2: Connect your resistor to the breadboard. Connect a wire from one side of the resistor to pin 4 on your Arduino board. Connect the other side of the resistor to pin 2. Connect that same side of the resistor (The one that goes to pin 2) to a long wire, ending in the metal object of your choice. See the images for a more visual explanation.
Step 3: Open up a new Arduino sketch and paste in the following code:
#include <CapacitiveSensor.h>
CapacitiveSensor cs_4_2 = CapacitiveSensor(4,2); // 10 megohm resistor between pins 4 & 2, pin 2(millis() - start); // check on performance in milliseconds
Serial.print("\t"); // tab character for debug window spacing
Serial.println(total1); // print sensor output 1
delay(10); // arbitrary delay to limit data to serial port
}
Step 4: Compile and upload your sketch to the Arduino. Open up the serial monitor. The first number is the time (in milliseconds) the board uses to process the calculations. The second number is the reading you're getting from the cap sensor.
And presto! It's done. Not the most exciting result, I know. But every great journey starts with a single step.
Step 4: Design Tips
Now that you're ready to use capacitive sensors in your own projects, there are a few things you should consider when designing your projects:
1. Do you really, REALLY need a capacitive sensor?
Meaning, is there any other sensor that can also do the job? If you need to sense proximity, a light sensor might work. If you want to measure pressure, a pressure sensor could do the trick. Capacitive sensors are wildly unstable, and require constant calibration, unless they are in a perfectly controlled environment. They're great for situations where you want to avoid any mechanical stress on a switch, as the user doesn't ever need to really be touching the sensor itself. Meaning, you can go all Scandinavian on your projects and make wooden switches, for instance. Or invisible ones. Another great advantage is the the sensor will only be activated by human touch, which could go a long way in making sure that electronics don't activate on their own in your suitcase.
2. Grounding is everything.
During testing (Which you can see in the video at the end of the 'ible) we found out that even taking your shoes off while activating a cap sensor will have a huge impact on the signal strength. If the Arduino is powered by a computer, plugging the computer to a wall socket might double or even triple the signal strength. Increased negative charge equals increased signal strength.
3. Cover up your sensors.
Not just because it looks cool, but also because it helps to stabilise your signal. You don't need more than a piece of clear cellotape, but you could take it so far as to fully enclose the sensor in a solid material, such as ABS plastic.
4. Use smoothing in your code.
If you followed the tutorial in step 3, you'll notice that the signal from a cap sensor can be highly erratic. Therefore it's a good idea to use some kind of smoothing function in your code. We used this one and it did a great job in stabilising the signal.
5. Control as much of the environment as possible.
Everything from air humidity to electromagnetic noise to someone touching a cable will affect the signal strength. Eliminate as many variables as you can. Using shielded cables and making sure no other electronic equipment is operating in the immediate vicinity are two easy precautions you can take. Solid grounding will also reduce interference.
6. Bigger surfaces = bigger signals.
The bigger the surface area of your sensor, the stronger your signal will be. A big surface area is also better for triggering the sensor at a distance.
Step 5: Cap Sensor Diagnostics Tool
Because there are so many variables that determine how strong the signal is, we decided it would be a good idea to have some sort of tool that would give us the ability to determine how suited a sensor would be at a glance. What we came up with is an Arduino device that can be hooked up to any surface with an LED bar graph that will light up according to how strong the signal received from the surface is. Since the reading from one surface might be tenfold that of another surface, we also included two sensitivity knobs. One for the minimum reading, and one for the maximum. Through testing we found that you really only need the maximum reading knob, so feel free to exclude the lower threshold knob. We did not use any resistors for our LEDs, and after using the device for a couple of days, it's still working fine, but there's no telling if and when they'll stop working. If you choose to use resistors, it's probably a good idea to hook them up to 5V instead of 3.3V.
You will need:
1 x Arduino board. We used an Arduino Uno.
10 x LEDs. We used one red, seven whites and two blues, but use whatever you want/have.
2 x Potentiometers. You can exclude one if you want, as the usefulness of a knob to control the lower threshold of the device is questionable.
7 x 4,7 MOhm resistors. That's what we used, but you can use a different amount if you want. The more resistors you have, the greater the resistance range you can explore. The lower values they have, the higher the resolution of the resistance range.
Electric cables
Breadboards (Optional)
Step 1: Wire up everything as shown in the fritzing diagram.
Step 2: Open up a new Arduino sketch and paste in the code below. The code uses a smoothing function for a more stable output. We used this code to get the LED bar graph lighting up correctly, making only slight modifications.
#include
const int ledCount = 10; // the number of LEDs in the bar graph
const long numReadings = 10;
int sensorPin1 = 0;
int sensorPin2 = A1;
long readings[numReadings];
long index = 0;
long total = 0;
long average = 0;
int ledPins[] = { 4, 5, 6, 7,8,9,10,11,12,13 }; // an array of pin numbers to which LEDs are attached
CapacitiveSensor cs_3_2 = CapacitiveSensor(3,2);
void setup() {
// loop over the pin array and set them all to output:
cs_3_2.set_CS_AutocaL_Millis(0xFFFFFFFF);
Serial.begin(9600);
for (int thisReading = 0; thisReading < numReadings; thisReading++) readings[thisReading] = 0;
for (int thisLed = 0; thisLed < ledCount; thisLed++) { pinMode(ledPins[thisLed], OUTPUT); } pinMode(sensorPin1,INPUT); pinMode(sensorPin2,INPUT);
}
void loop() {
int bottom;
int top;
bottom = analogRead(sensorPin1);
top = analogRead(sensorPin2);
int bottommap;
int topmap;
bottommap = map(bottom,0,1023,0,3000);
topmap = map(top,0,1023,100,30000);
long start = millis();
long total1 = cs_3_2.capacitiveSensor(30);
total= total - readings[index];
readings[index] = total1;
total= total + readings[index];
index = index + 1;
if (index >= numReadings)
index = 0;
average = total / numReadings;
Serial.print(millis() - start);
Serial.print("\t");
Serial.print(bottom); Serial.print("\t");
Serial.print(top);
Serial.print("\t");
Serial.println(average);
delay(10);
int sensorReading = average;
int ledLevel = map(sensorReading, bottommap, topmap, 0, ledCount);
for (int thisLed = 0; thisLed < ledCount; thisLed++) {
if (thisLed < ledLevel) {
digitalWrite(ledPins[thisLed], LOW); }
else { digitalWrite(ledPins[thisLed], HIGH); } }
}
Step 3: You're done! Compile and upload the sketch to the Arduino and you should be able to get a more graphical output of the signal strength. Add or remove resistors to increase or decrease the signal strength. More resistors means more strength. We mounted a series of resistors on a separate breadboard so that we could change the resistance faster. Turn the potentiometer connected to A1 to increase or decrease sensitivity.

J.
The following code shows one way of deploying a JSON service:
@BindingType(JSONBindingID.JSON_BINDING)
@WebService
public class MyService {
public Book get(@WebParam(name="id") int id) {
Book b = new Book();
b.id = id;
return b;
}
public static final class Book {
public int id = 1;
public String title = "Java";
}
}
The JSON extension comes with the equivalent of "wsimport" tool, but in a JavaScript style. Once the service is deployed, JavaScript client can load the proxy code like this:
<script src="path/to/endpoint?js"></script>
With that, it can now make service invocations as shown in the following code. The call happens asynchronously, and upon the completion the callback is invoked with the response. This is a trivial example, but since this is built on top of JAXB, it can handle any JAXB annotated beans, just like your SOAP service does.
myService.get(
{id:5},
function(r) {
alert("ID="+r.id);
alert("title="+r.title);
}
);
The neat thing about this extension is that the system takes advantage of the schema information inside WSDL to produce JSON that looks more natural. I believe this is an unique feature not seen elsewhere in a simliar toolkit. This information is also used to generate the documentation page, so that developers writing client code can learn what format the request and the response are, without knowing anything about XML Schema. See the screenshot below to get some idea of how it looks like:
This is a part of the JAX-WS commons project, which hosts a bunch of JAX-WS related extensions, utilities, tools, etc. Anyone interested in hosting any code around the JAX-WS are welcome to join the project.

CodePlexProject Hosting for Open Source Software
Hi everyone,
I just started exploring the possibilities of the kinect. I want to do some post processing with opencv on the video streams.
I was able to read the video stream by the possibilty of the pygame surface to export its content as numpy array.
Then I converted this array than to an opencv matrix...
Is there is easier / more straight forward way to access the video data from the kinect with opencv in python?
Thank you in advance!
I think you can skip the pygame surface by constructing a new array and then using the ctypes attribute so you can copy memory into it, something like:
arr = numpy.empty(320*240, numpy.uint16) # 16-bit 320x240 resolution for the depth stream, change appropriately for the video stream
def depth_frame_ready(frame):
frame.image.copy_bits(arr.ctypes.data) # copy into the array
I haven't tested it but I think something like that should work.

I would like to see expanded supported for domain specific languages. I know Jetbrains has worked on a very ambitious project to that effect, but perhaps it was before the market wanted it? Even simpler stuff like being able to provide a grammar for error and syntax highlighting would be fantastic.
Dmitry Jemerov
Our very ambitious project is alive and well, thanks.
Most of traditional grammar files are not a good fit for error highlighting because they don't really support error recovery: after one error they get into an error state and the rest of the file cannot be highlighted correctly. Hand-coded recursive descent parsers, which we use for our own language plugins, do not suffer from this problem, and our plugin API allows you to write such parsers for your own languages since IDEA version 5. So it's not exactly clear what additional support could be provided.

Is the JSP WYSIWUG is planned in near future or distant future. At least a way to navigate between the JSP designer elements and it's JSP code counterpart like RAD is very much welcome. I have requested this for so many times. Please include this in Diana.
My 2 cents: as multicore machines are getting more common, I would like some ability to run JUnit tests in multiple threads at once, to speed them up. (Such test runner threads would have to run in separate JVMs then, to avoid breaking tests that rely on static variables). (If this is something that can easily be achieved with a plug-in, I might consider writing such a plug-in myself.)

Don't make your tests rely on static variables.

Wish somebody would build a Java IDE that is optimized for pure Java source coding and that is super fast, without tons of J2EE, external framework, you name it here, features that makes it slow and hard to use. Kinda like IntelliJ 2 from 2002.
Actually, can JetBrains re-release older versions?
Why don't give a try??
I disabled some plugins and modify my idea.vmoptions as this
-server
-Xms500m
-Xmx1500m
-XX:MaxPermSize=400m
-ea
-XX:+UseConcMarkSweepGC
And is pretty fast comparing with 5 or 6 versions
I'm sorry about being unclear. This is really to be able to edit openlazslo files, they
can look like this: They essentially are a combo of declarative XML and Javascript, I know
there was talk about a plugin for OpenLaszlo, this is really based on a relax-ng schema that can
expend. Unfortunately this is an either / or, and what I'm really after is IDEA's awesome
xml parsing as well as the JS syntax checking.
This whole thing I know is tricky as the classing in openlaszlo leads to an extensible
schema, not a beautiful thing in a xsd/dtd, but the relax-ng plugin will not allow me to
parse this correctly either.
(Example)
<view name="letterclipper" clip="true" width="330" height="100" x="93" y="336" bgcolor="white">
<method event="oninit">
this.setAttribute("relX",0);
</method>
<view name="lettercontainer" x="45" y="0"
bgcolor="gray" width="102" height="0">
<wrappinglayout axis="x" spacing="12"/>
<dataset name="lds" src="http:titles_test.xml" type="http" request="true"/>
<handler reference="lds" name="ondata">
Debug.write("Current width : " + canvas.letterclipper.lettercontainer.getWidth());
<![CDATA[
Debug.write("remotedata test data loaded", this);
Debug.write(this.lds);
Debug.write(this);
var id;
var name;
var iconUrl;
var nodes = lds.getElementsByTagName("titles")[0].childNodes;
for (n in nodes)
]]>
</handler>
<method event="oninit">
this.animate( "x", 0 , 1, false );
</method>
<method name="scrollRight" args="pixels">
<![CDATA[
var distX = Math.round(parent.getAttribute("relX") - pixels)
var actualX = Math.max( Math.min(distX,0) , -this.width/2 );
Debug.write("Current width: " + this.getWidth());
if (actualX > distX)
else
Debug.write("Distx: " + distX + " to: " + actualX );
]]>
</method>
<method name="scrollLeft" args="pixels">
<![CDATA[
var distX = Math.round(parent.getAttribute("relX") + pixels)
var actualX = Math.max( Math.min(distX,0) , -this.width/2 );

Sounds like you should try the IntelliLang plugin to get support for editing JavaScript inside XML tags.
BTW: Your code fragment works just fine for me when it is associated with the RELAX-NG schema for OpenLaszlo available here (well, it shows "wrappinglayout" as incorrect, but in fact this tag is not present in the schema either). You need to put your root tag into OpenLaszlo's namespace and associate this with the schema file. This will give full error checking and completion based on the schema.
If there are specific problems with either the IntelliLang or the RELAX-NG plugin, don't hesitate to ask me either per mail or in the plugin forum. Please note that both plugins are not available for the Diana EAP yet.? | https://confluence.jetbrains.com/display/IDEADEV/Diana+First+EAP+Release+Notes?focusedCommentId=38729 | CC-MAIN-2021-21 | refinedweb | 1,254 | 55.54 |
TraditionmyVariable = 50let myConstant = 42
A constant or variable must have the same type as the value you want to assign to it. However, you don’t always have to write the type explicitly. Providing a value when you create a constant or variable lets the compiler inferlet implicitDouble = 70.0let explicitDouble: Double = 70
EXPERIMENT:- Create a constant with an explicit type of Float and a value of 4
let label = "The width is "let width = 94letlet oranges = 5let appleSummary = "I have \(apples) apples."let fruitSummary = "I have \(apples + oranges) = """I said "I have \(apples) apples."And then I said = [:]
Control Flow
Use if and switch to make conditionals, and use for-in, while, and repeat-while to make loops. Parentheses around the condition or loop variable are optional. Braces around the body are required.
let individualScores = [75, 43, 103, 87, 12]var teamScore = 0for score in individualScores {if score > 50 {teamScore += 3} else {teamScore += 1}}print(teamScore)
In an if statement, the conditional must be a Boolean expression—this means that code such as if score { ... } is an error, not an implicit comparison to zero.)var optionalName: String? = "John Appleseed"var greeting = "Hello!"if let name = optionalName {greeting = "Hello, \(name)"}let fullName: String = "John Appleseed"let informalGreeting = "Hi \(nickName ?? fullName)".")}
EXPERIMENT:- Try removing the default case. What error do you get?
Notice how let can be used in a pattern to assign the value that matchedfor (kind, numbers) in interestingNumbers {for number in numbers {if number > largest {largest = number}}}print(largest)while n < 100 {n *= 2}print(n)var m = 2repeat {m *= 2} while m < 100print(m)
You can keep an index in a loop by using ..< to make a range of indexes.
var total = 0for i in 0..<4 {total += i}print(total).
unc greet(person: String, day: String) -> String {return "Hello \(person), today is \(day)."}greet(person: "Bob", day: "Tuesday")
EXPERIMENT:-for score in scores {if score > max {max = score} else if score < min {min = score}sum += score}return (min, max, sum)}let statistics = calculateStatistics(scores: [5, 3, 100, 3, 9])print(statistics.sum)print(statistics.2)
Functions can be nested. Nested functions have access to variables that were declared in the outer function. You can use nested functions to organize the code in a function that is long or complex.
func returnFifteen() -> Int {var y = 10func.

This version of the Shape class is missing something important: an initializer to set up the class when an instance is created. Use init to create one.

et optionalSquare: Square? = Square(sideLength: 2.5, name: "optional square")let sideLength = optionalSquare?.sideLength
Enumerations and Structures
Use enum to create an enumeration. Like classes and all other named types, enumerations can have methods associated with them.
enum Rank: Int {case ace = 1case two, three, four, five, six, seven, eight, nine, tencase jack, queen, kingfunc simpleDescription() -> String {switch self {case .ace:return "ace"case .jack:return "jack"case .queen:return "queen"case .king:return "king"default:return String(self.rawValue)}}}let ace = Rank.acelet aceRawValue = ace.rawValue
EXPERIMENT:-func simpleDescription() -> String {switch self {case .spades:return "spades"case .hearts:return "hearts"case .diamonds:return "diamonds"case .clubs:return "clubs"}}}let hearts = Suit.heartsletvar suit: Suitfunc simpleDescription() -> String {return "The \(rank.simpleDescription()) of \(suit.simpleDescription())"}}let threeOfSpades = Card(rank: .three, suit: .spades)let threeOfSpadesDescription = threeOfSpades.simpleDescription()
EXPERIMENT:- Add a method to Card that creates a full deck of cards, with one card of each combination of rank and suit.
Protocols and Extensions
Use protocol to declare a protocol.
rotocol ExampleProtocol {var simpleDescription: String { get }mutating func adjust()}
Classes, enumerations, and structs can all adopt protocols.
class SimpleClass: ExampleProtocol {var simpleDescription: String = "A very simple class."var anotherProperty: Int = 69105func adjust() {simpleDescription += " Now 100% adjusted."}}var a = SimpleClass()a.adjust()let aDescription = a.simpleDescriptionstructprintcase noTonercase"}
There are several ways to handle errors. One way is to use do-catch. Inside the do block, you mark code that can throw an error by writing try in front of it. Inside the catch block, the error is automatically given the name error unless you give it a different name.
do {let printerResponse = try send(job: 1040, toPrinter: "Bi Sheng")print(printerResponse)} catch {print(error)}")
Use defer to write a block of code that is executed after all other code in the function, just before the function returns. The code is executed regardless of whether the function throws an error. You can use defer to write setup and cleanup code next to each other, even though they need to be executed at different times.
var fridgeIsOpen = falselet fridgeContent = ["milk", "eggs", "leftovers"]func fridgeContains(_ food: String) -> Bool {fridgeIsOpen = truedefer {fridgeIsOpen = false}let result = fridgeContent.contains(food)return result}fridgeContains("banana")print(fridgeIsOpen)
Generics
Write a name inside angle brackets to make a generic function or type.
func makeArray<Item>(repeating item: Item, numberOfTimes: Int) -> [Item] {var result = [Item]()for _ in 0..<numberOfTimes {result.append(item)}return result}makeArray(repeating: "knock", numberOfTimes: 4)
You can make generic forms of functions and methods, as well as classes, enumerations, and structures.
// Reimplement the Swift standard library's optional typeenum OptionalValue<Wrapped> {case nonecase some(Wrapped)}var possibleInteger: OptionalValue<Int> = .nonepossibleInteger = .some(100)
Use where right before the bodywhere T.Iterator.Element: Equatable, T.Iterator.Element == U.Iterator.Element {for lhsItem in lhs {for rhsItem in rhs {if lhsItem == rhsItem {return true}}}return false}anyCommonElements([1, 2, 3], [3])
EXPERIMENT:- Modify the anyCommonElements(_:_:) function to make a function that returns an array of the elements that any two sequences have in common.

to this point we have been concerned mainly with tools to access and operate on array data with NumPy. This section covers algorithms related to sorting values in NumPy arrays. These algorithms are a favorite topic in introductory computer science courses: if you've ever taken one, you probably have had dreams (or, depending on your temperament, nightmares) about insertion sorts, selection sorts, merge sorts, quick sorts, bubble sorts, and many, many more. All are means of accomplishing a similar task: sorting the values in a list or array.
For example, a simple selection sort repeatedly finds the minimum value from a list, and makes swaps until the list is sorted. We can code this in just a few lines of Python:
import numpy as np def selection_sort(x): for i in range(len(x)): swap = i + np.argmin(x[i:]) (x[i], x[swap]) = (x[swap], x[i]) return x
x = np.array([2, 1, 4, 3, 5]) selection_sort(x)
array([1, 2, 3, 4, 5])
As any first-year computer science major will tell you, the selection sort is useful for its simplicity, but is much too slow to be useful for larger arrays. For a list of $N$ values, it requires $N$ loops, each of which does on order $\sim N$ comparisons to find the swap value. In terms of the "big-O" notation often used to characterize these algorithms (see Big-O Notation), selection sort averages $\mathcal{O}[N^2]$: if you double the number of items in the list, the execution time will go up by about a factor of four.
Even selection sort, though, is much better than my all-time favorite sorting algorithms, the bogosort:
def bogosort(x): while np.any(x[:-1] > x[1:]): np.random.shuffle(x) return x
x = np.array([2, 1, 4, 3, 5]) bogosort(x)
array([1, 2, 3, 4, 5])
This silly sorting method relies on pure chance: it repeatedly applies a random shuffling of the array until the result happens to be sorted. With an average scaling of $\mathcal{O}[N \times N!]$, (that's N times N factorial) this should–quite obviously–never be used for any real computation.
Fortunately, Python contains built-in sorting algorithms that are much more efficient than either of the simplistic algorithms just shown. We'll start by looking at the Python built-ins, and then take a look at the routines included in NumPy and optimized for NumPy arrays.
np.sortand
np.argsort¶
Although Python has built-in
sort and
sorted functions to work with lists, we won't discuss them here because NumPy's
np.sort function turns out to be much more efficient and useful for our purposes.
By default
np.sort uses an $\mathcal{O}[N\log N]$, quicksort algorithm, though mergesort and heapsort are also available. For most applications, the default quicksort is more than sufficient.
To return a sorted version of the array without modifying the input, you can use
np.sort:
x = np.array([2, 1, 4, 3, 5]) np.sort(x)
array([1, 2, 3, 4, 5])
If you prefer to sort the array in-place, you can instead use the
sort method of arrays:
x.sort() print(x)
[1 2 3 4 5]
A related function is
argsort, which instead returns the indices of the sorted elements:
x = np.array([2, 1, 4, 3, 5]) i = np.argsort(x) print(i)
[1 0 3 2 4]
The first element of this result gives the index of the smallest element, the second value gives the index of the second smallest, and so on. These indices can then be used (via fancy indexing) to construct the sorted array if desired:
x[i]
array([1, 2, 3, 4, 5])
A useful feature of NumPy's sorting algorithms is the ability to sort along specific rows or columns of a multidimensional array using the
axis argument. For example:
rand = np.random.RandomState(42) X = rand.randint(0, 10, (4, 6)) print(X)
[[6 3 7 4 6 9] [2 6 7 4 3 7] [7 2 5 4 1 7] [5 1 4 0 9 5]]
# sort each column of X np.sort(X, axis=0)
array([[2, 1, 4, 0, 1, 5], [5, 2, 5, 4, 3, 7], [6, 3, 7, 4, 6, 7], [7, 6, 7, 4, 9, 9]])
# sort each row of X np.sort(X, axis=1)
array([[3, 4, 6, 6, 7, 9], [2, 3, 4, 6, 7, 7], [1, 2, 4, 5, 7, 7], [0, 1, 4, 5, 5, 9]])
Keep in mind that this treats each row or column as an independent array, and any relationships between the row or column values will be lost!
Sometimes we're not interested in sorting the entire array, but simply want to find the k smallest values in the array. NumPy provides this in the
np.partition function.
np.partition takes an array and a number K; the result is a new array with the smallest K values to the left of the partition, and the remaining values to the right, in arbitrary order:
x = np.array([7, 2, 3, 1, 6, 5, 4]) np.partition(x, 3)
array([2, 1, 3, 4, 6, 5, 7])
Note that the first three values in the resulting array are the three smallest in the array, and the remaining array positions contain the remaining values. Within the two partitions, the elements have arbitrary order.
Similarly to sorting, we can partition along an arbitrary axis of a multidimensional array:
np.partition(X, 2, axis=1)
array([[3, 4, 6, 7, 6, 9], [2, 3, 4, 7, 6, 7], [1, 2, 4, 5, 7, 7], [0, 1, 4, 5, 9, 5]])
The result is an array where the first two slots in each row contain the smallest values from that row, with the remaining values filling the remaining slots.
Finally, just as there is a
np.argsort that computes indices of the sort, there is a
np.argpartition that computes indices of the partition.
We'll see this in action in the following section.
Let's quickly see how we might use this
argsort function along multiple axes to find the nearest neighbors of each point in a set.
We'll start by creating a random set of 10 points on a two-dimensional plane.
Using the standard convention, we'll arrange these in a $10\times 2$ array:
X = rand.rand(10, 2)
To get an idea of how these points look, let's quickly scatter plot them:
%matplotlib inline import matplotlib.pyplot as plt import seaborn; seaborn.set() # Plot styling plt.scatter(X[:, 0], X[:, 1], s=100);
Now we'll compute the distance between each pair of points. Recall that the squared-distance between two points is the sum of the squared differences in each dimension; using the efficient broadcasting (Computation on Arrays: Broadcasting) and aggregation (Aggregations: Min, Max, and Everything In Between) routines provided by NumPy we can compute the matrix of square distances in a single line of code:
dist_sq = np.sum((X[:, np.newaxis, :] - X[np.newaxis, :, :]) ** 2, axis=-1)
This operation has a lot packed into it, and it might be a bit confusing if you're unfamiliar with NumPy's broadcasting rules. When you come across code like this, it can be useful to break it down into its component steps:
# for each pair of points, compute differences in their coordinates differences = X[:, np.newaxis, :] - X[np.newaxis, :, :] differences.shape
(10, 10, 2)
# square the coordinate differences sq_differences = differences ** 2 sq_differences.shape
(10, 10, 2)
# sum the coordinate differences to get the squared distance dist_sq = sq_differences.sum(-1) dist_sq.shape
(10, 10)
Just to double-check what we are doing, we should see that the diagonal of this matrix (i.e., the set of distances between each point and itself) is all zero:
dist_sq.diagonal()
array([ 0., 0., 0., 0., 0., 0., 0., 0., 0., 0.])
It checks out!
With the pairwise square-distances converted, we can now use
np.argsort to sort along each row. The leftmost columns will then give the indices of the nearest neighbors:
nearest = np.argsort(dist_sq, axis=1) print(nearest)
[[0 3 9 7 1 4 2 5 6 8] [1 4 7 9 3 6 8 5 0 2] [2 1 4 6 3 0 8 9 7 5] [3 9 7 0 1 4 5 8 6 2] [4 1 8 5 6 7 9 3 0 2] [5 8 6 4 1 7 9 3 2 0] [6 8 5 4 1 7 9 3 2 0] [7 9 3 1 4 0 5 8 6 2] [8 5 6 4 1 7 9 3 2 0] [9 7 3 0 1 4 5 8 6 2]]
Notice that the first column gives the numbers 0 through 9 in order: this is due to the fact that each point's closest neighbor is itself, as we would expect.
By using a full sort here, we've actually done more work than we need to in this case. If we're simply interested in the nearest $k$ neighbors, all we need is to partition each row so that the smallest $k + 1$ squared distances come first, with larger distances filling the remaining positions of the array. We can do this with the
np.argpartition function:
K = 2 nearest_partition = np.argpartition(dist_sq, K + 1, axis=1)
In order to visualize this network of neighbors, let's quickly plot the points along with lines representing the connections from each point to its two nearest neighbors:
plt.scatter(X[:, 0], X[:, 1], s=100) # draw lines from each point to its two nearest neighbors K = 2 for i in range(X.shape[0]): for j in nearest_partition[i, :K+1]: # plot a line from X[i] to X[j] # use some zip magic to make it happen: plt.plot(*zip(X[j], X[i]), color='black')
Each point in the plot has lines drawn to its two nearest neighbors. At first glance, it might seem strange that some of the points have more than two lines coming out of them: this is due to the fact that if point A is one of the two nearest neighbors of point B, this does not necessarily imply that point B is one of the two nearest neighbors of point A.
Although the broadcasting and row-wise sorting of this approach might seem less straightforward than writing a loop, it turns out to be a very efficient way of operating on this data in Python. You might be tempted to do the same type of operation by manually looping through the data and sorting each set of neighbors individually, but this would almost certainly lead to a slower algorithm than the vectorized version we used. The beauty of this approach is that it's written in a way that's agnostic to the size of the input data: we could just as easily compute the neighbors among 100 or 1,000,000 points in any number of dimensions, and the code would look the same.
Finally, I'll note that when doing very large nearest neighbor searches, there are tree-based and/or approximate algorithms that can scale as $\mathcal{O}[N\log N]$ or better rather than the $\mathcal{O}[N^2]$ of the brute-force algorithm. One example of this is the KD-Tree, implemented in Scikit-learn.
Big-O notation is a means of describing how the number of operations required for an algorithm scales as the input grows in size. To use it correctly is to dive deeply into the realm of computer science theory, and to carefully distinguish it from the related small-o notation, big-$\theta$ notation, big-$\Omega$ notation, and probably many mutant hybrids thereof. While these distinctions add precision to statements about algorithmic scaling, outside computer science theory exams and the remarks of pedantic blog commenters, you'll rarely see such distinctions made in practice. Far more common in the data science world is a less rigid use of big-O notation: as a general (if imprecise) description of the scaling of an algorithm. With apologies to theorists and pedants, this is the interpretation we'll use throughout this book.
Big-O notation, in this loose sense, tells you how much time your algorithm will take as you increase the amount of data. If you have an $\mathcal{O}[N]$ (read "order $N$") algorithm that takes 1 second to operate on a list of length N=1,000, then you should expect it to take roughly 5 seconds for a list of length N=5,000. If you have an $\mathcal{O}[N^2]$ (read "order N squared") algorithm that takes 1 second for N=1000, then you should expect it to take about 25 seconds for N=5000.
For our purposes, the N will usually indicate some aspect of the size of the dataset (the number of points, the number of dimensions, etc.). When trying to analyze billions or trillions of samples, the difference between $\mathcal{O}[N]$ and $\mathcal{O}[N^2]$ can be far from trivial!
Notice that the big-O notation by itself tells you nothing about the actual wall-clock time of a computation, but only about its scaling as you change N. Generally, for example, an $\mathcal{O}[N]$ algorithm is considered to have better scaling than an $\mathcal{O}[N^2]$ algorithm, and for good reason. But for small datasets in particular, the algorithm with better scaling might not be faster. For example, in a given problem an $\mathcal{O}[N^2]$ algorithm might take 0.01 seconds, while a "better" $\mathcal{O}[N]$ algorithm might take 1 second. Scale up N by a factor of 1,000, though, and the $\mathcal{O}[N]$ algorithm will win out.
Even this loose version of Big-O notation can be very useful when comparing the performance of algorithms, and we'll use this notation throughout the book when talking about how algorithms scale. | https://nbviewer.org/github/jakevdp/PythonDataScienceHandbook/blob/master/notebooks/02.08-Sorting.ipynb | CC-MAIN-2022-40 | refinedweb | 2,351 | 66.57 |

comment:2 Changed 3 years ago by
I had a look at this and I came up with two ways to fix it.
- Allow passing the hostname to the socket, either in the constructor or in the Connect call.
- Store the hostname in BNetworkAddress
I gave the first option a try and it was more work than I expected and it crashes in the Connect call of BSecureSocket now. I added the SSL_set_tlsext_host_name call there and perhaps I am doing something wrong here. What is the best way to figure out what is going wrong? Attach a patch with my changes?
Implementing the first option gave me the idea that the second option would be better, but I don't know the network code good enough to say for certain that it is better.
As both of the proposed changes are on the Haiku side, we perhaps also need to take into account backwards compatibility.
comment:3 Changed 3 years ago by
The second solution would be preferred.
As you said, the changes are on Haiku side which means this can be tested more easily with a small test application just doing one HTTPS request. Said app can then be put into Debugger for a closer analysis.
Note: this is the same problem that currently prevents accessing freelists.org from Web+.
As for backward compatibility, the BUrlRequest family of classes isn't considered stable yet. I don't think BNetworkAddress is, either (BeOS compatibility is ensured with the BNetAddress class). The changes do require some coordination still, probably they will need a rebuild of WebKit as they are delivered to the repo.
comment:4 Changed 3 years ago by
comment:5 Changed 3 years ago by
I finally had time to try the second solution and got something working. It even works without needing a new version of Web+ to be built. I added a private variable fHostName to BNetworkAddress and filled it in when the SetTo call contained a host. This does mean that if you make a call to a SetTo function without a host, it will not enable the SNI support. Not sure what to do about that. Thought about adding a host parameter to those SetTo functions, but decided against it for now. I used the existing HostName function to return fHostName, but left the TODO in place. Not sure if we want to do something extra in case fHostName is empty. Made some changes in SecureSocket to get the host name from the BNetworkAddress and use it to make the SSL_set_tlsext_host_name call. Only did it for Connect, but perhaps Accept needs to be changed as well.
Tested some sites (freelists, slashdot) that didn't work without it and confirmed that with my changes they work fine. Also tested some other sites that were already working to make sure I didn't break anything and it seems fine.
comment:6 Changed 3 years ago by
Looks good in general, I see some possible changes/improvements (this is open to discussion):
- In SecureSocket, _SetupConnect is checking for NULL, I think it should also check for an empty string as that's what String() will return (as used in Connect).
- When there is no hostname, the given IP address could be converted to a string and used ("127.0.0.1" or whatever). I'm not sure if this is of any use.
- This should also be tested outside Web+, in particular when 302 redirects are involved, because Web+ handles those on its own and does not use the HttpRequest code for that. We should make sure that the behavior is still correct in that case (the redirected host should be used for the second connection).
comment:7 Changed 3 years ago by
- Good point regarding the NULL check, I will add it
- Won't the IP address be used automatically as that is what will be passed in as host to the SetTo functions? I don't think it will be of any use as that is not the intent of the SNI support.
- Is there some documentation on the BHTTPRequest class? I have never done any coding with it and it I can't seem to reach to check for documentation.
comment:8 Changed 3 years ago by
It seems the website is currently offline.
For examples of use of BHttpRequest you can have a look in src/tests/kits/network (and if possible, adding more tests there for the new features would be nice).
Yes, giving the IP address to SNI may not be a very good idea. I'm not sure any certificate provider would deliver a cert for an IP without domain, anyway.
comment:9 Changed 3 years ago by
How do I compile and run those tests? Regarding the 302 redirect, I see that the test website used in those unit tests can do a redirect, but to which url would we try the redirect? If it is a unit test, it would be convenient if it always kept working, so I'm not sure redirecting to freelists is a good idea.
comment:10 Changed 3 years ago by
jam -q UnitTests will build the tests, then you get an UnitTester command which is the test harness for running them (IIRC in generated/tests/bin or somewhere around there, have a look at the articles on about "unit tests").
The tests with online services are not the best solution, as a first step we could redirect to freelists, but ideally we should run these with a local HTTP server. I don't know if PoorMan is up to the task or if we should use lighttpd or some other available server. This will require a lot more work than just fixing this particular bug, so maybe we can keep that for a later stage.
comment:11 Changed 3 years ago by
Thanks, I will give that a try. I will fix the NULL check and update the current patch and I will have a look at the tests. I noticed that th test website has a https version that fails to load with the current version of Web+, while it works if I apply my patch, so at least that should be a good test.
comment:12 Changed 3 years ago by
Updated the patch with a fix for the NULL check. Will look at the unit tests next. I'm thinking of making a separate patch for that.
comment:13 Changed 3 years ago by
Ping. Can this just be merged, or are we waiting for the unit tests?
comment:14 Changed 3 years ago by
I think I see a bug in the patch. Sorry for not reviewing earlier.
In
BNetworkAddress::SetTo(const char* host, const char* service, uint32 flags) , you changed the error handling. I think you forgot to change
== B_OK to
!= B_OK as in the other variant. This is something that unit tests would probably catch.
With this issue fixed the patch is ok to merge as is. I don't want to put unit test burden on people trying to contribute to Haiku, we should fix our own mess there...

Regarding the style in the SetTo() functions; the previous style is preferable. Errors with early return, etc., make the code easier to follow and also reduces indentation.
comment:17 Changed 3 years ago by
comment:18 Changed 3 years ago by
That's not what the code was doing. It was returning early on success, which meant that any value that needed to be done on success needed to be done in multiple places. This was already happening with fStatus and adding fHostName multiple times seemed to me to make it worse.
Also, in general I dislike multiple exit points in a function, but if the coding style is to prefer this then I will keep it in mind for other patches.
comment:19 Changed 3 years ago by
There is some disagreement on the way this was done on the mailing list after the change was pushed (I don't know why people waited for this to happen before reviewing...). Adding the link here in case you don't read haiku-commits daily:
It seems this is a one line change on OpenSSL level:
However, BSecureSocket does not know the hostname (it gets the already resolved BNetworkAddress).

If so we are limited to a smallish number of discs for now.If not (and partitions are packed densely) then changing thepartitioning of a drive could be awkward.Finally, how do I say that I want the root filesystem to be on aparticular "mdp" device+partition. I cannot assume that my devicewill be the first to register with the "disk" layer, so I cannot besure that "root=/dev/diska1" will work.Maybe a boot line option like: diska=mdp,0could be used. Each device that registers with "disk" defines a__setup handler for "disk" which checks if it should register as aparticular "disk".So if "mdp" finds that there is an mdp device 0, and wants to registerit with "disk" then: if "diskX=mdp,0" is a boot option for some X, register it with "disk" as device "X-'a'" else register it with "disk" as "largest-available-device".Does that make sense? It feels a bit ugly thoughThe brick wall the I feel that I am hitting is that there needs tobe a name space to communicate device identities between kernelspaceand userspace. You are saying that major numbers are no longer to bethat namespace (at least, not for new drivers) so we have to come upwith a new namespace, which will obviously involve textual names.There seem to be three options: 1/ devfs - but not everybody likes that (and there are certainly aspects that I am uncomfortable with) 2/ ugly hacks like the above and like name_to_kdev_t 3/ "something else" which either hasn't been proposed or hasn't been agreed on. (I have my own ideasbut insufficient time).I guess your goal in establishing the moratorium on new majors is toforce people to break down this brick wall, either by accepting devfs,pushing through ugly hacks, or finding that "something else".I'll keep looking for a sledgehammer:-)NeilBrown-To unsubscribe from this list: send the line "unsubscribe linux-kernel" inthe body of a message to majordomo@vger.kernel.orgMore majordomo info at read the FAQ at | http://lkml.org/lkml/2001/5/15/89 | CC-MAIN-2016-50 | refinedweb | 609 | 59.74 |

Handling No Email Found When Resetting Passwords4:39 with Jason Seifer
So far we've written and tested the successful case of having an email found for a user requesting a password reset. Now it's time to test the failure scenarios where someone is requesting a password reset for an email that doesn't exist in our application.
Code Snippets
def create if user user = User.find_by(email: params[:email]) user.generate_password_reset_token! Notifier.password_reset(user).deliver redirect_to login_path else flash.now[:error] = "Email not found" render action: 'new' end end
- 0:00
Okay, when we last left off, we tried our code in person and we saw an error, so
- 0:05
now let's go ahead and write our tests to cover this particular error.
- 0:11
We had in our tests already what would happen only if the user is
- 0:14
successfully found.
- 0:15
What we need to do is check to see if the user is not found, and
- 0:18
then handle those cases as well.
- 0:23
So we have this context with a valid user in email.
- 0:29
So let's go ahead and create one for a context with no user.
- 0:41
And we'll just say it renders the new page.
- 0:59
And what'll happen is if the user isn't found,
- 1:02
it'll just bring them right back to that password reset form.
- 1:05
I'm gonna stop my server here.
- 1:12
Okay, undefined method password reset token for nil:NilClass,
- 1:17
that was the same error that we just got in the browser and that is online 31.
- 1:22
So this is actually a pretty easy fix.
- 1:24
What we'll do is we'll say, if the user is found then we do these things.
- 1:36
And if not, we render the new action.
- 1:40
Clear my screen and run that again.
- 1:44
Okay.
- 1:45
And let's also set the flash message here.
- 2:12
So we'll just give them a little message saying that the email wasn't found.
- 2:17
And we can do that in the same action that we render by saying flash.now.
- 2:25
By saying Email not found.
- 2:29
Now let's run that and see what happens.
- 2:33
Okay, that looks good.
- 2:36
Although that makes me think that we should also set the flash message up here.
- 2:54
We're gonna expect the flash success message to be set.
- 3:05
We'll say check your email for the new password.
- 3:22
Here we go.
- 3:23
Let's go ahead and run that.
- 3:27
Okay, that passes, great.
- 3:31
Turn our server again, and see how that looks.
- 3:36
Actually if I run this, there we go, email not found.
- 3:43
All right, let me sign up.
- 3:54
Okay great, got some todo lists in here whatever I'm just gonna log out right now.
- 4:00
Forgot my password.
- 4:07
Okay password reset instructions sent, please check your email.
- 4:10
Now, we're not actually gonna be able to send emails in development mode but,
- 4:15
if I look at the server log, it says I can reset my password here.
- 4:24
So, let's go ahead and see what that looks like.
- 4:26
I copy it and I paste it.
- 4:30
Haven't done anything yet.
- 4:32
That means that we need to actually implement resetting the password.
- 4:37
So we're gonna go ahead and start on that in our next video. | https://teamtreehouse.com/library/user-authentication-with-rails/password-resets-and-testing/handling-no-email-found-when-resetting-passwords | CC-MAIN-2016-44 | refinedweb | 645 | 83.86 |

This command is used for inserting and removing tracks related to the shots displayed in the Sequencer. It can also be used to modify the track state, for example, to lock or mute a track. In query mode, return type is based on queried flag.
Derived from mel command maya.cmds.shotTrack
Example:
import pymel.core as pm # Move the shot named "shot2" to track 3 # pm.shotTrack( 'shot2', track=3 ) # Lock the track containing the shot named "shot1" # pm.shotTrack( 'shot1', lock=True ) # Remove any empty tracks # pm.shotTrack(removeEmptyTracks=True) # shotTrack -q -track shot1; # pm.shotTrack( 'shot1', q=True, track=True ) | http://www.luma-pictures.com/tools/pymel/docs/1.0/generated/functions/pymel.core.system/pymel.core.system.shotTrack.html#pymel.core.system.shotTrack | crawl-003 | refinedweb | 103 | 79.26 |
OSB: How to recreate reusable XQuery functions
edited Jun 21, 2013 4:57AM in SOA Suite Discusssions
OSB's XQuery implementation does not support the XQuery "module" which allows the creation of a function library so how can OSB provide function re-use?
Answers
- Hi,
i'm sorry...The Oracle Service Bus XQuery engine fully supports all of the language features that are described in the World Wide Web (W3C) specification for XQuery with one exception: modules
bye
- So how do other people avoid having to copy and paste XQuery methods from one XQuery transformation to another?
- In fact another possibility i use is the following.
Create an xquery application that you want to re-use, for example:
create_header($pars).
Then within another XQueries (create_message) you have to use the header as an external parameter, example (ASSIGN is the assign within a OSB pipeline)
ASSIGN $header := create_header($pars)
ASSIGN $message := create_message($header, $otherparameters)
This is not exactly what you want but you have created re-use and are able to unit test the xquery.
- Yes that kind of helps for "course" grained functions but gets clunky when trying to be more fine grained.
Is there any moves by the OSB development team to fully support XQuery 1.0 and the Module functionality in particular? It seems a pretty basic limitation to me and causes lots of "code duplication" that has to be maintained...
- any plans for making it available on OSB?
- May be you can define custom XPath functions for fine grained utilities.
Here is a good article on how to define custom XPath functions on OSB 11G.
- What we did is creating a seperate project in which we use most of XQuery stuff, using SaxonSA library to run and validate the queries.
This project adds the following possibilities for xqueries:
- Schema validation of XPath used in XQueries (including namespaces)
- XQuery syntax validation (with errors at the exact line and position where it fails.
- Allows the use of modules
- Reqression testing XQueries
Regrettably we can not do Java callout's from XQueries as this is not supported on the ESB.
We also build a simple 'flattener' that takes a module based, schema enriched XQuery and then generates the XQuery that can be used on the ESB itself. The flattened query is also regression tested.
Although it was quite some work to make it, it already has paid back the initial costs of the project in the second or third project we did. We since then have enhanced the project so it also can do regression message flow validation on the OSB (we already had valid input and output messages).
The tool also greatly improves the stability of the code on the OSB, and reduces development time as we can build the XQuery from a unit test environment that will point out typos and other xpath related problems.
We do have some fairly complex xqueries on the OSB, the number of xqueries in the project at the moment is 187 with 250 unittests.
So, if Oracle is not going to include it in the OSB itself (which seems lilkely at the moment), you can build such a system yourself !

- Hey mdsrobbins,
we have exactly the same problem. OSB XQuery code reusability is close to zero.
We have a hugh amount of transformations and unfortunaly we need to copy custom functions to all them. Nowadays our code is hard to maintain and message data enrichment is difficult to manage. We sadly need this functionality.
I have tested to outsource our code in custom functions by Java packages. Functionality was indeed available, but live editing is not possible due to compiled Java classes. Unless these custom functions are not deployable with WLST, we will not be capable to deliver fully automated OSB deployments. Besides, versioning the JAR next to the sbconfigs takes its effort on top (every additional artefact extends versioning complexity).
Does someone know, if the module import in OSB XQuery will be available in following releases (11g and up)?
Many greetings
same question,
Does someone know, if the module import in OSB XQuery will be available in following releases (11g and up)?
XQuery modules are very important for us. We have a huge amount of xq ressources and copy all our functions from one to another. Very frustrating. We need module import feature in OSB.
many greetings!

+1 I've always found the protections stuff in zope.app.security particularly icky, though never thought that it would cause that much trouble. For compatability reasons, zope.app.security._protections and the protect() function inside (though empty) should probably still exist for at least another release because people might be using it in their own tests (even though it's not public API). A deprecation warning could tell them it's going a way -- should be a piece of cake with Stephan's deprecation framework. > The __name__ and __parent__ setting smells like it ought to go in zcml > to me as well, but it is not currently causing a problem because the > mutable it modifies is not reset for tests (which also perhaps should > be revisited). I'm not proposing to change any of that for now. Ok. Maybe there should be a collector issue about this so that we remember it for upcoming releases. > Thoughts?

I share Fred's concerns, but given the ickiness of the problem, I wouldn't mind if this was fixed for 3.1, assuming the hold up for the second release candidate wasn't more than just another day or two.

If you're referring to this test: main() { sleep(500); } I didn't do that test on MSVC. That won't even compile on MSVC since sleep isn't defined.

Hey guys, I have the assignment of writing the Towers of Hanoi program then testing it. I already got help measuring the time of the program, but that is not what my professor wanted he wanted to count the iterations. I can't get it down, my program will run but it will not print out correctly.
This is the code I was using.
import TerminalIO.KeyboardReader; public class towers { public static void main(String[] args) { KeyboardReader reader = new KeyboardReader(); int numberofRings = reader.readInt("Enter number of Rings: "); move (numberofRings, 1, 3, 2); } static void move(int n, int i, int j, int k) { int count = 0; if (n > 0) { move(n - 1, i, k, j); System.out.println("Move ring " + n + "from peg" + i + "to" + j); move(n - 1, k, j, i); count++; } System.out.println(count+ "Is the number of Moves"); } }
And it keeps printing out
0 Is the number of Moves
Move ring 1 from peg 1 to 2
0 Is the number of Moves
1 Is the number of Moves
Move ring 2 from peg 1 to 3
0 Is the number of Moves
and repeating

I have tried 4 different HC-SR04 sensors, and 2 different Arduino Uno boards, and when the ping is out of range, I normally get 0cm (as I should with NewPing). However, sprinkled in with the 0cm readings are 5cm, 6cm, 7cm, 8cm, 9cm readings. I have tried changing the delay from 30 mS to 100 mS, and get the same variation when out of range.
I am powering the ultrasonic sensor with +5V from the Arduino, and using a 2 wire system. The sensor works fine when in range.
Any ideas?
Here is my test code:
#include <NewPing.h> #define TRIGGER_PIN 2 #define ECHO_PIN 3 #define MAX_DISTANCE 200 int distance; NewPing sonar(TRIGGER_PIN, ECHO_PIN, MAX_DISTANCE); void setup() { Serial.begin(115200); } void loop() { distance = (sonar.ping_cm()); while (distance == 0) //NewPing is supposed to return 0 { //when ping is out of range distance = (sonar.ping_cm()); delay(50); } Serial.print(distance); Serial.println("cm"); delay(50); } | https://forum.arduino.cc/t/hc-sr04-with-newping-library-returning-numbers-other-than-zero-when-out-of-range/429576 | CC-MAIN-2021-39 | refinedweb | 154 | 65.62 |

Everyone has handles, nicknames based on their skills.
But what would your hacker handle be?
Well with Python we can make our own Hacker Handle and here is how.
Coding the project
I wrote this project using Trinket.io so that I can embed working code into this web page. But you can easily write this code on your Raspberry Pi, PC, Mac using Python 3 editor (IDLE3) or using another Python editor (PyCharm, Sublime Text etc)
Imports
In Python we start by importing something called "shuffle" from a library called random...but what does that mean? Python has a library, pre-written code that contains extra functionality. In this case the random library contains code to create random numbers, random choice, and importantly for us...shuffling data as if we were shuffling a deck of cards. Because we just need the shuffle functionality we shall import the library a little differently to normal.
from random import shuffle
Lists, the most powerful tool on the planet
With that complete we now create a list of cool hacker handles. In Python a list is a form of data storage. We can store lots of different types of data, such as
- Strings - Our hacker handles are strings
- Integers - Numbers with no decimal place
- Floats - Numbers with a decimal place
A list uses an index to allocate a position to each item in the list. For example the first item in a list has an index of 0, and then each new item receives an index that increases by 1.
In the code below, handles[0] is "Zero" and handles[10] is "Burn".
handles = ["Zero", "Acid", "Max", "Random", "Giga", "Absolute", "Cool", "Gibson", "Cereal", "Killer", "Burn", "Crash", "Override", "Razor", "Blade", "Polaroid", "Pi"]
Everybody's shuffling....
So now that we have our list of cool hacker handles, lets use the shuffle functionality to...shuffle the names. To do that we call the shuffle function, and pass the name of the list to it inside parenthesis ( ), this is called an "argument" and it is used to pass extra information to a function.
shuffle(handles)
Hack the planet with ASCII art!!!!
Hackers love to use ASCII (American Standard Code for Information Interchange) art in their hacks...well that's what Hollywood taught me. So I created my own homage to that.
print(""" HH HH kk HH HH aa aa cccc kk kk HHHHHHH aa aaa cc kkkkk HH HH aa aaa cc kk kk HH HH aaa aa ccccc kk kk TTTTTTT hh TTT hh eee TTT hhhhhh ee e TTT hh hh eeeee TTT hh hh eeeee PPPPPP lll tt !!! PP PP lll aa aa nn nnn eee tt !!! PPPPPP lll aa aaa nnn nn ee e tttt !!! PP lll aa aaa nn nn eeeee tt PP lll aaa aa nn nn eeeee tttt !!! """)
You can make you own via this website
Who am I?
So what is my hacker handle? Obviously mine has to be "Pi Killer" because of my love for Greggs pies... but what is your hacker handle?
Well to find out we use a print function, and inside the function we write a string to say "Your hacker handle is" and then we print the values stored in the "handles" list, specifically those stored at index 0 and 1. Now these values are shuffled every time the code is run, so you should see a different name each time.
print("Your hacker handle is",handles[0],handles[1])
So if you are following along at home, run the code in your Python editor to see your cool hacker handle.

Paths on Grids
Authors: Nathan Chen, Michael Cao, Benjamin Qi, Andrew Wang
Contributor: Maggie Liu
Counting the number of "special" paths on a grid, and how some string problems can be solved using grids.
Prerequisites
Focus Problem – try your best to solve this problem before continuing!
Focus Problem – try your best to solve this problem before continuing!
TutorialTutorial
A common archetype of DP Problems involves a 2D grid of square cells (like graph paper), and we have to analyze "paths." A path is a sequence of cells whose movement is restricted to one direction on the -axis and one direction on the -axis (for example, you may only be able to move down or to the right). Usually, the path also has to start in one corner of the grid and end on another corner. The problem may ask you to count the number of paths that satisfy some property, or it may ask you to find the max/min of some quantity over all paths.
Usually, the sub-problems in this type of DP are a sub-rectangle of the whole grid. For example, consider a problem in which we count the number of paths from to when we can only move in the positive -direction and the positive -direction.
Let be the number of paths in the sub-rectangle whose corners are and . We know that the first cell in a path counted by is , and we know the last cell is . However, the second-to-last cell can either be or . Thus, if we pretend to append the cell to the paths that end on or , we construct paths that end on . Working backwards like that motivates the following recurrence: . We can use this recurrence to calculate . Keep in mind that because the path to is just a single cell. In general, thinking about how you can append cells to paths will help you construct the correct DP recurrence.
When using the DP recurrence, it's important that you compute the DP values in an order such that the dp-value for a cell is known before you use it to compute the dp-value for another cell. In the example problem above, it's fine to iterate through each row from to :
C++
for(int i = 0; i < M; i++) {for(int j = 0; j < N; j++) {if(j > 0) dp[j][i] += dp[j - 1][i];if(i > 0) dp[j][i] += dp[j][i - 1];}}
Java
for(int i = 0; i < M; i++) {for(int j = 0; j < N; j++) {if(j > 0) dp[j][i] += dp[j - 1][i];if(i > 0) dp[j][i] += dp[j][i - 1];}}
Python
for i in range(M):for j in range(N):if j > 0:dp[j][i] += dp[j - 1][i]if i > 0:dp[j][i] += dp[j][i - 1]
Note how the coordinates in the code are in the form (x coordinate, y coordinate). Most of the time, it's more convenient to think of points as (row, column) instead, which swaps the order of the coordinates, though the code uses the former format to be consistent with the definition of .
Solution - Grid PathsSolution - Grid Paths
In this problem, we are directly given a 2D grid of cells, and we have to count the number of paths from corner to corner that can only go down (positive direction) and to the right (positive direction), with a special catch. The path can't use a cell marked with an asterisk.
We come close to being able to use our original recurrence, but we have to modify it. Basically, if a cell is normal, we can use the recurrence normally. But, if cell has an asterisk, the dp-value is , because no path can end on a trap.
The code for the DP recurrence doesn't change much:
C++
#include <bits/stdc++.h>using namespace std;typedef long long ll;bool ok[1000][1000];ll dp[1000][1000];int main() {
Java
import java.util.*;import java.io.*;public class Main {public static void main(String[] args) throws Exception {BufferedReader br = new BufferedReader(new InputStreamReader(System.in));int N = Integer.parseInt(br.readLine());long dp[][] = new long[N][N];
Python
n = int(input())ok = [[char == "." for char in input()] for _ in range(n)]dp = [[0] * n for _ in range(n)]dp[0][0] = 1for i in range(n):for j in range(n):# if current square is a trapif not ok[i][j]:dp[i][j] = 0
Note how the coordinates are now in the form (row, column) when reading in the input.
Solution - Longest Common SubsequenceSolution - Longest Common Subsequence
The longest common subsequence is a classical string problem, but where's the grid?
In fact, we can create a grid to solve it. Think about the following algorithm to create any (not necessarily the longest) subsequence between two strings and :
- We start with two pointers, , and , each beginning at .
- We do some "action" at each time step, until there are no more available "actions". An "action" can be any of the following:
- Increase the value of by (only works if ).
- Increase the value of by (only works if ).
- Increase the value of and by only if . Append that character (or ) to the common subsequence. (only works if and ).
- We know that this process creates a common subsequence because characters which are common to both strings are found from left to right.
This algorithm can also be illustrated on a grid. Let and . Then, the current state of the algorithm can be defined as a specific point using the values of and that we discussed previously. The process of increasing pointers can be seen as moving right (if is increased), moving down (if is increased), or moving diagonally (if both and increase). See that each diagonal movement adds one to the length of the common subsequence.
Now, we re-phrase "the length of the longest increasing subsequence" as "the maximum number of 'diagonal movements' ("action 3" in the above algorithm) in a path from the top-left corner to the bottom-right corner on the grid." Thus, we have constructed a grid-type DP problem.
In the above grid, see how the bolded path has diagonal movements at characters "a" and "c". That means the longest common subsequence between "xabcd" and "yazc" is "ac".
Based on the three "actions", which are also the three possible movements of the path, we can create a DP-recurrence to find the longest common subsequence:
C++
class Solution {public:int longestCommonSubsequence(string a, string b) {int dp[a.size()][b.size()];for (int i = 0; i < a.size(); i++) {fill(dp[i], dp[i] + b.size(), 0);}for (int i = 0; i < a.size(); i++) {if(a[i] == b[0]) dp[i][0] = 1;if(i != 0) dp[i][0] = max(dp[i][0], dp[i - 1][0]);
Ben - shorter version using macros:
Code Snippet: Benq Template (Click to expand)class Solution {public:int longestCommonSubsequence(str a, str b) {V<vi> dp(sz(a) + 1, vi(sz(b) + 1));F0R(i, sz(a) + 1) F0R(j, sz(b) + 1) {if (i < sz(a)) ckmax(dp[i + 1][j], dp[i][j]);if (j < sz(b)) ckmax(dp[i][j + 1], dp[i][j]);if (i < sz(a) && j < sz(b))ckmax(dp[i + 1][j + 1], dp[i][j] + (a[i] == b[j]));}return dp[sz(a)][sz(b)];}};
Java
class Solution {public int longestCommonSubsequence(String a, String b) {int[][] dp = new int[a.length()][b.length()];for (int i = 0; i < a.length(); i++) {if(a.charAt(i) == b.charAt(0)) dp[i][0] = 1;if(i != 0) dp[i][0] = Math.max(dp[i][0], dp[i-1][0]);}for (int i = 0; i < b.length(); i++) {if(a.charAt(0) == b.charAt(i)) {dp[0][i] = 1;
Python
class Solution:def longestCommonSubsequence(self, a: str, b: str) -> int:dp = [[0] * (len(b) + 1) for _ in range(len(a) + 1)]for i in range(1, len(a) + 1):for j in range(1, len(b) + 1):if a[i - 1] == b[j - 1]:dp[i][j] = dp[i - 1][j - 1] + 1else:dp[i][j] = max(dp[i - 1][j], dp[i][j - 1])return dp[len(a)][len(b)]

PRIVATE banking is meant to be boring. But somehow UBS, the world's largest private bank, forgot that. Some of its employees, in their zeal to win the business of wealthy Americans with a predilection for fibbing to the taxman, seem to have confused discretion with spycraft. Instead of waiting for clients to come to it in Switzerland, the bank trained some members of staff in counter-surveillance techniques, equipped them with encrypted laptops and secret e-mail addresses and then infiltrated them into America to meet clients, according to American prosecutors.
The price of such subterfuge has been high. On February 18th UBS agreed to pay fines of $780m and to hand the American authorities the names and account details of up to 300 clients. A week later Marcel Rohner, its youthful chief executive, unexpectedly stepped down.
Although he is credited with having salvaged what he could of UBS by raising capital early, and he helped it withstand steep losses and a slumping share price during 20 months at the helm, Mr Rohner could not, it seems, entirely escape his past. Although not accused of any wrongdoing, he was head of the wealth-management business when many of the shenanigans are alleged to have occurred.
More galling, perhaps, is that Mr Rohner was replaced by Oswald Grübel, a veteran former chief executive of Credit Suisse, UBS's archrival. Mr Grübel unashamedly copied UBS's strategy of combining commercial, investment and private banking, but without the missteps that led UBS so disastrously into American subprime mortgages. UBS shares rose immediately after his appointment, but he has a huge task ahead of him. Not least is the damage UBS's private bankers have done over the bank's, and its home country's, reputation for bank secrecy.
Their antics paid handsomely for a while. The offshore-banking business of UBS gathered some $20 billion in assets from at least 20,000 American clients, earning the bank some $200m a year, according to prosecutors. The government reckons that some 17,000 of these clients omitted to mention their numbered Swiss bank accounts when filling in their American tax returns. Although illegal in America and most other parts of the world, under Swiss law this is no crime.
There may be a fine distinction between someone who has simply forgotten to include everything on a tax return (an oversight that even treasury secretaries are occasionally prone to) and someone who has gone out of their way to evade tax. Yet fraud is illegal in Switzerland as well as in America.
UBS seems to have crossed the line, either by helping some clients set up dummy companies and sham accounts to hide money from the taxman, or by turning a blind eye when they did. The number of clients who did this was small, about 250, but by helping them UBS not only exposed itself to prosecution in America but also endangered Switzerland's status as a secretive piggy-bank for the world's rich.
It was a capitulation shared with Switzerland's financial regulator, which allowed UBS to release their names, saying that a criminal prosecution could ultimately have put the bank's existence at risk. But it was not a total cave-in. The bank and Swiss authorities are still hewing to the distinction in Swiss law between sins of omission and of commission. They will, for instance, contest in court a separate demand from America's Internal Revenue Service (IRS) that UBS hand over the names of the 52,000 American account-holders it is thought to have.
Even a partial surrender, however, may spook wealthy clients. Champions of bank secrecy see it as the fraying of a tradition that has withstood wars, pressure from powerful states and the prying eyes of foreign spies. “They are trying to save UBS because it is systemically important but they are sacrificing the rest of us,” says Konrad Hummler, who heads the Swiss Private Bankers Association.
At risk is up to $2 trillion in offshore assets held in Swiss private banks (see chart). There are also important questions at stake about the reach of the state and a citizen's right to privacy.
Those who press for an end to banking secrecy argue that people who hide their assets have shifty motives, such as to avoid paying taxes. That includes John DiCicco, of America's Justice Department, who pointed to the millions of Americans losing their jobs, homes and health care while “more than 50,000 of the wealthiest among us have actively sought to evade their civic and legal duty to pay taxes”. Some say as much as $255 billion a year slips through tax nets around the world.
Yet many rich people want to keep their money away from prying eyes for reasons other than to avoid tax, including those fearing divorce settlements. Others want to keep their money safe from expropriation by fickle governments, and hidden from thieving criminals.
Stefan Jaecklin, of Oliver Wyman, a consultancy, reckons that much of the new money that flowed into Switzerland in recent years came from countries with low or no personal income taxes, such as the Gulf, and that a rapidly increasing share of money coming from European countries with high rates of tax is declared to the authorities. The lure, he says, is not only the secrecy but also the industry's well-established competence.
Even the most ardent defenders of banking secrecy concede that the tide is turning against it, however. In the rich world, the mood against all big banks has soured, including offshore ones. At the G20 meeting in April, European leaders want to discuss potential sanctions against tax havens that refuse to hand over information held by their banks.
Mr Grübel, as much as anyone in Switzerland, has a huge stake in the outcome of this debate. For all the problems he faces managing the investment bank, the private bank is still crucial to UBS's survival.

Apache OpenOffice (AOO) Bugzilla – Full Text Issue Listing
I've been playing with the XHTML export feature and discovered a few annoying
issues:
1. The output doesn't contain the DOCTYPE. Setting the DOCTYPE through the
Transformation tab in XML Filter Settings does nothing. I've tweaked
main_html.xsl to specify the DOCTYPE, but the generated string is not ok.
Instead of
<!DOCTYPE HTML PUBLIC...
it should say
<!DOCTYPE html PUBLIC...
2. The output contains loads of xml namespace prefixes. I tweaked it by changing
exclude-result-prefixes="java" to exclude-result-prefixes="the_whole_list_of
prefixes". Don't know if it's good or bad, but it worked for me.
3. The META element is not closed, therefore resulting in numerous error reports
by the validator.
Haven't seen 1.1RC3 yet, possibly some of those issues are resolved in this release.
I wish we can follow the standard
we need to recheck everything beside this on the suggestion
At first: Sorry for being late but the tooling set the first owner
wrong . It has been corrected today.
Enhancement:
It's correct that we are not valid for now. That's what Svante told me
and that it is the future to be valid.
Target will be only Office later - another only if Svante has it
already on his 'roadmap' for OOo 2.0?!
Set correct sub component.
I am aware of the unvalidness of the XHTML and it is a certainly my
personal goal to make it valid.
To your concerns:
1. I didn't bring in the doctype, as it is not valid, so nobody should
get the idea to write bugs about it yet.
2. Seems to be a parser / processor problem, sorry I can not reproduce
3. A unclosed meta tag is not even well-formed XML, this is a XSLT
processor problem for sure.
Believe me, I am anoyed with this missing feature as you are, and I
gave dozen of hours of private working time into the stylesheets, but
I don't think that the marketing hang up the XSLT filter high in
priority for the next time. Despite of that, I think that it will
exchange the current HTML filter some day.
Currently, I have little time to spend on the filter, but I nearly got
a new version finished (unpublished), and if you like to work with me
on it, I would be very happy if we could make this filter to our
filter and raise it up to product quality.
Problems of XHTML (transient) validness I figured out are:
- Nested paragraphs in case draw:text-box include a paragraph
- Anchor names have to be transformed accordingly to XHTML specs
Thanks for offering your help, Leonid.
I make the updated files soon accessible as download.
With my filterxslt01 CWS (childworkspace), I gonna fix at least some of theses
problems, we should specify detailed problems and write follow up bugs.
--> changed target to OOo2.0
- Added title and base element to header
- Made several changes to changes to tables and paragraph nestling
The remaining problems will be splittet into several add-on bugs explaining the
problem.
I suggest to start with transitional and work afterwards further on strict.
Simply add
doctype-system=""
respectivly
doctype-system=""
to the xsl:output element of the stylesheet.
I added a tough test document (the OpenOffice Specification).
Validness might be tested by multiple tools (e.g. W3C Validator).
KNOWN TRANSIENT VALIDNESS PROBLEM:
Nesting of paragraph in a span element.
KNOWN STRICT VALIDNESS PROBLEM:
Table Alignment:
To align a table horizontal, I created a surrounding div tag. Obviously that
wasn't a valid solution in strict XHTML.
Added my officeless xslt environment, first >4MB environment with XALAN &
XERCES, but don't download it, it is buggy with one document.
Simply install a JDK/JRE1.4, so you would use an earlier XALAN & XERCES version,
without the issue.
The environement is without the stylesheets, which are added separately.
Hopefully someone is able to help me out with this, I am not able to plan time
for this issue and want to close CWS (ChildWorkSpace) end of next week (if
someone needs more time we can take expand it a week longer). If noone helps, I
have to move this issue out of the CWS.
Created attachment 12395 [details]
xslt environment (updated stylesheets, testfiles, processor (XT with patch)) use it with JDK/JRE 1.4 (Xerces/Xalan)
Tested the stylesheets in the Office and realized, that the office filter does
not provide any parameter at all for the stylesheets.
Wrote #i24398 (i.e.), so
relative links (when document stored to a different directory as the origion and
links to zipped graphics (JAR URLs) will remain.
Unfortunatly the XHTML filter is compatible to zipped OOo/unzipped OOo and flat
OOo by parameters. The URL of the meta and styles xml file given as parameters.
Due to this, I rewrote the internally usage of global variable to a global data
parameter (cmp. stylesheets attached).
By this new enhancement, the new filter works with the StarOffice 7 as well
(better than ever).
For compatibility reasons renamed the starting stylesheets 'ooo2xhtml.xsl' back
to 'main_html.xsl'. To use these new stylesheets in your office simply unzip the
stylesheets (xhtml and common folder) into your <OFFICE>/share/xslt directory
(e.g. C:\Program Files\StarOffice7\share\xslt).
Created attachment 12591 [details]
Latest stylesheets (renamed oo2xhtml.xsl to main_html.xsl for OOo usage)
To use in directly in StarOffice / OpenOffice not in stand-alone test
environment, please rename the 'ooo2xhtml.xsl' stylesheet to 'main_html.xsl'.
Added the default XHTML strict public DTD to figure out if there are further
constraints.
If further constraints are being noticed, please add a new enhancement task with
a detailed description of the specific problem.
SUS->JSI: For testing transform any arbitrary document and validate the XML
output with a 3rd party tool (e.g. XML Spy) and/or you may use the TEST
environment in the XML Filter Settings and validate with the Office.
Reassign to QA
SUS: Changed issue type to FEATURE as discussed with JSI, feature mail will follow
Now we're exporting - first time ever (!) - valid XHTML files! If there is a big
in XSLT transformation (and we have some issues open) the validation may fail
but a big percent of documents have been exported correctly.
Verified. Also if we do not support some issues (like graphics at the moment)
the export also in draw / impress is valid!
ok.

Encapsulation is nothing new to what we have read. It is the method of combining the data and functions.
Why Encapsulation
Encapsulation is necessary to keep the details about an object hidden from the users of that object. Details of an object are stored in its data members (member bables). This is the reason we make all the member variables of a class private and most of the member functions public. Member variables are made private so that these cannot be directly accessed from outside the class (to hide the details of any object of that class like how the data about the object is implemented) and so most member functions are made public to allow the users to access the data members through those functions.
For example, we operate a washing machine through its power button. We switch on the power button, the machine starts and when we switch it off, the machine stops. We don't know what mechanism is going on inside it. That is encapsulation. (public, private, protected). For example, if a data member is declared private and we wish to make it directly accessible from anywhere outside the class, we just need to replace the specifier private by public.
Let's see an example of Encapsulation.
#include <iostream> using namespace std; class Rectangle { int length; int breadth; public: void setDimension(int l, int b) { length = l; breadth = b; } int getArea() { return length * breadth; } }; int main() { Rectangle rt; rt.setDimension(7, 4); cout << rt.getArea() << endl; return 0; }
The member variables length and breadth are encapsulated inside the class Rectangle. Since we declared these private, so these variables cannot be accessed directly from outside the class. Therefore , we used the functions 'setDimension' and 'getArea' to access them.

Creating a clock in Dev C++
Posted 12 May 2010 - 09:24 PM
Why hello there. As the title implies, I'm trying to create a clock in Dev C++. It works fine but I don't want the cout<<hour<<":"<<minutes<<":"<<n<<endl; part to keep displaying. I want the seconds, minutes, and hours to iterate accordingly but I don't want the cout statement to keep repeating itself. What can I do to fix this?

I'm in the process of learning Java and I cannot find any good explanation on the
implements Closeable
implements AutoCloseable
interface Closeable
public void close() throws IOException
pw.close();
IOstream
import java.io.*;
public class IOtest implements AutoCloseable {
public static void main(String[] args) throws IOException {
File file = new File("C:\\test.txt");
PrintWriter pw = new PrintWriter(file);
System.out.println("file has been created");
pw.println("file has been created");
}
@Override
public void close() throws IOException {
}
It seems to me that you are not very familiar with interfaces. In the code you have posted you don't need to implement
AutoCloseable.
You will only have to (or should) implement
Closeable or
AutoCloseable if you are about to implement an own
PrintWriter which handles with files or any other resources which needs to be closed.
In your implementation it is enough to call
pw.close(). You should do this in a finally block:
PrintWriter pw = null; try { File file = new File("C:\\test.txt"); pw = new PrintWriter(file); } catch (IOException e) { System.out.println("bad things happen"); } finally { if (pw != null) { try { pw.close(); } catch (IOException e) { } } }
The code above is Java 6 related. In Java 7 this can be done more elegant (see this answer). | https://codedump.io/share/idFj7P2ZgANK/1/implements-closeable-or-implements-autocloseable | CC-MAIN-2016-44 | refinedweb | 207 | 58.99 |
Hello,
My assistant has been beating the stick at this for a few days and I’ve figured it out this morning, and we have found nothing on this forum about this. End up to be simple, but you need to know some facts (dataset vs pydataset, self vs event.source and List vs Tuple)
I’ve decided to post it to help others
How I got it to work is to create a project function that create the list of tuples from a dataset:
project.dd script
def ddTable(dtaList): dtaList = system.dataset.toPyDataSet(dtaList) ##Change dataset to PyDataSet dtaList2 = [] #creating the List of tuple to be returned for row in dtaList: dtaList2.append( (row[0], row[1])) ## appending the tuple to the list return dtaList2
In my case the datasets (dtaCol1, dtaCol2) are a RootContainer Custom Property. The powerable is on the RootContainer too. If your dataset is a custom property of the powertable, just lose the ‘.parent’ in my call. And rename Col1, Col2 , dtaCol1 and dtaCol2 to what ever your powertable Columns and Datasets are. And add or subtract column as much as you need. In my case I have 2 powertable columns with a dropdown each.
So the powertable configureEditor’s Script calls the function like this
def configureEditor(self, colIndex, colName): if colName == 'Col1': return {'options': project.dd.ddTable(self.parent.dtaCol1)} elif colName == 'Col2': return {'options': project.dd.ddTable(self.parent.dtaCol2)} | https://forum.inductiveautomation.com/t/powertable-dynamic-custom-dropdown/11602 | CC-MAIN-2021-39 | refinedweb | 239 | 64.3 |
Most, if not all, GUI platforms support the idea of events, and events are very heavily used in GUI programming. As an example, consider a button. Buttons don’t exist on their own but are used as part of a user interface and are contained by some other item. This item is usually a form, but it could also be some other control, such as a toolbar.
The whole point of having a button on a form is so that the user can click it to tell the program something. For example, “the user clicked the OK button, so dismiss the dialog box” or “the user clicked the Print button on the toolbar, so print the document.”
Events provide a formalized, standard mechanism that lets event sources (such as a button) hook up with event receivers (such as a form). Events in the .NET Framework implement a publish-and-subscribe mechanism, where event sources make public the events that they will raise—they publish them—and event receivers tell the source which events they’re interested in—they subscribe to events. Event receivers can also unsubscribe when they no longer want to receive a particular event.
Events in the .NET Framework are based on multicast delegates, and it isn’t too hard to see how this will work. An event source declares a delegate for each event it wants to generate, such as Click, DoubleClick, and so on. An event receiver then defines suitable methods and passes them to the event source, which uses Combine to add them to its multicast delegates. When the time comes to fire the event, the event source calls Invoke on the delegate, thus calling the requisite functions in the receivers.
The actual event mechanism simplifies the syntax so that you don’t have to deal with delegates directly, and it’s designed to fit in with the event mechanism that already exists in Visual Basic. The following exercise takes you through creating an event source class and event receiver classes that register themselves with the source and use the events when they’re fired.
Open Visual Studio. NET if it isn’t already open, and create a new Visual C++ Console Application (.NET) project named Event.
Event sources and receivers use delegates, so define a delegate for each of the events raised by the source. In this example, two events will be used, so open the
Event.cpp source file and define the following two delegates immediately after the using namespace System; line:
// Delegates __delegate void FirstEventHandler(String*); __delegate void SecondEventHandler(String*);
The delegates define the signatures of the methods that event receivers have to implement to handle the events, so they’re often given names that end with Handler. Each of these events will simply pass a string as the event data, but you can make the data passed as complex as you want.
Add the implementation of the event source class to the source file like this:
// Event source class __gc class EvtSrc { public: // Declare the events __event FirstEventHandler* OnFirstEvent; __event SecondEventHandler* OnSecondEvent; // Event raising functions void RaiseOne(String* pMsg) { OnFirstEvent(pMsg); } void RaiseTwo(String* pMsg) { OnSecondEvent(pMsg); } };
The first thing to note is the use of the __event keyword to declare two events. You need one __event declaration for each event that you want to raise, and its type is that of the delegate associated with the event. So, in the case of the first event object, the type is FirstEventHandler* to match the FirstEventHandler delegate. Using the __event keyword causes the compiler to generate a lot of delegate handling code for you; if you’re interested in exactly what’s going on, see the following sidebar, “How Does the __event Keyword Work?”
You can then use the event objects in the EvtSrc class to raise the events, simply by using them as if they were function calls and passing the appropriate argument.
The __event keyword isn’t only used in managed code, but can also be used to describe events in native C++ classes and COM events.
When you declare an __event member for a class in managed code, the compiler generates code to implement the underlying delegate mechanism. For the OnFirstEvent event object in the exercise, you get the following methods generated:
add_OnFirstEvent, a public method that calls Delegate::Combine to add a receiver to this event’s invocation list. Rather than calling add_OnFirstEvent directly, you use the += operator on the event object, which calls the function for you.
remove_OnFirstEvent, a public method that calls Delegate::Remove to remove a receiver from this event’s invocation list. As with the add_ function, you don’t call this method directly but instead use the -= operator on the event object.
raise_OnFirstEvent, a protected method that calls Delegate::Invoke to call all the methods on this event’s invocation list.
The raise method is protected so that it can be called only through the proper channels and not directly by client code.
You now have a class that can be used to fire events, so the next thing you need is a class that will listen for events and act on them when they’ve been generated.
Add a new class to the project named EvtRcv.
// Event receiver class __gc class EvtRcv { EvtSrc* theSource; public: };
The receiver has to know the event sources it’s working with to be able to subscribe and unsubscribe, so add an EvtSrc* member to the class to represent the one source you’ll be working with.
Add a constructor to the class that takes a pointer to an EvtSrc object and checks that it isn’t null. If the pointer is valid, save it away in the EvtSrc* member.
EvtRcv(EvtSrc* pSrc) { if (pSrc == 0) throw new ArgumentNullException("Must have event source"); // Save the source theSource = pSrc; }
Define the member handler functions in EvtRcv that EvtSrc is going to call. As you know from our discussion of delegates, the signatures of these methods will have to match the signatures of the delegates used to define the events, as shown here:
// Handler functions void FirstEvent(String* pMsg) { Console::WriteLine("EvtRcv: event one, message was {0}", pMsg); } void SecondEvent(String* pMsg) { Console::WriteLine("EvtRcv: event two, message was {0}", pMsg); }
FirstEvent is the handler for the FirstEventHandler delegate, and SecondEvent is the handler for the SecondEventHandler delegate. Each of them simply prints out the string that they’ve been passed.
Once you have the handlers defined, you can subscribe to the event source. Edit the constructor for the EvtRcv class so that it looks like the following code:
EvtRcv(EvtSrc* pSrc) { if (pSrc == 0) throw new ArgumentNullException("Must have event source"); // Save the source theSource = pSrc; // Add our handlers theSource->OnFirstEvent += new FirstEventHandler(this, &EvtRcv::FirstEvent); theSource->OnSecondEvent += new SecondEventHandler(this, &EvtRcv::SecondEvent); }
You subscribe to an event using the += operator. In the code, you’re creating two new delegate objects, which will call back to the FirstEvent and SecondEvent handlers on the current object. This is exactly the same syntax you’d use if you were manually creating a delegate. The difference is in the += operator, which combines the newly created delegate with the event source’s multicast delegate.
As you read in the preceding sidebar, += calls the compiler-generated add_OnFirstEvent method, which in turn calls Delegate::Combine.
Although you’ve subscribed to all the events automatically in the constructor, you could also use member functions to subscribe to individual events as required.
A matching -= operator lets you unsubscribe from events. Add the following member function to EvtRcv, which will unsubscribe from the first event:
// Remove a handler void RemoveHandler() { // Remove the handler for the first event theSource->OnFirstEvent -= new FirstEventHandler(this, &EvtRcv1::FirstEvent); }
The syntax for using the -= operator to unsubscribe is exactly the same as that for the += operator to subscribe.
Now that you’ve written the event source and event receiver classes, you can write some code to test them out.
Edit the _tmain function to create event source and receiver objects.
int _tmain() { Console::WriteLine(S"Event Example"); // Create a source EvtSrc* pSrc = new EvtSrc(); // Create a receiver, and bind it to the source EvtRcv* pRcv = new EvtRcv(pSrc); return 0; }
The EvtSrc constructor takes no arguments, while the EvtRcv constructor has to be passed a valid EvtSrc pointer. At this point, the receiver is set up, listening for events to be fired from the source.
int _tmain() { Console::WriteLine(S"Event Example"); // Create a source EvtSrc* pSrc = new EvtSrc(); // Create a receiver, and bind it to the source EvtRcv* pRcv = new EvtRcv(pSrc); // Fire events Console::WriteLine(S"Fire both events:"); pSrc->RaiseOne(S"Hello, mum!"); pSrc->RaiseTwo(S"One big step"); return 0; }
Calls to the source’s RaiseOne and RaiseTwo functions tell it to fire both events. When you run this code, you should see output similar to the following figure.
The receiver has had both handlers called, so it has printed both the messages associated with the events.
Insert some code to call the RemoveHandler function of the receiver, and try firing both events again:
// Remove the handler for event one pRcv->RemoveHandler(); // Fire events again Console::WriteLine(S"Fire both events:"); pSrc->RaiseOne(S"Hello, mum!"); pSrc->RaiseTwo(S"One big step");
This time you should see only the second message printed because the receiver is no longer handling the first event. | https://flylib.com/books/en/3.295.1.104/1/ | CC-MAIN-2019-35 | refinedweb | 1,564 | 56.59 |

This change generalizes support for floating in case expressions. Previously, case expression with an unlifted scrutinee and a single DEFAULT alternative were floated in. In particular, this allowed array index operations to be floated in. We also want to float in SIMD unpack primops, which return an unboxed tuple of scalars, thus the generalization.

I have some looping wav samples that I play forward and reverse. When playing a sample forward, it loops fine. When playing in reverse and the beginning is met, it jumps to some point in the middle, not the end as I expect it to. On each particular file is seems to jump to the same position in the middle every time, but the position varies with each different wav. Any idea what is going on?
- dolphin asked 14 years ago
- You must login to post comments
I am not using (explicitly any way) loop points, is there any way I can muck with them to work around this? Or can I maybe use a callback to reposition the play point? (Does the end callback get called if you are plaing in reverse and you reach the beginning?) I think, at the very least, I should be able to poll the position in the sample every frame and move the position myself if it reaches the begining in reverse playback mode, but I am hoping for a better solution.
Aonther question: I am using F_API FSOUND_Sample_Lock to get a pointer to the wav file data, so I can draw the waveform. The function seems to always return false, but the pointer and length are valid after the return (the first ones, the second ones are both 0). Any idea what is going on there?

To make life simpler for developers, React has introduced a wide variety of hooks. In addition, React allows us to build our own custom hooks.
Today, I will explain how we can create and use React custom hooks.
What are Custom Hooks in React?
React custom hooks are a way to extract component logic into reusable functions. There is one convention you should know about before writing our own React hooks
"use" in front of the custom hook
React advises us to only use React hooks inside React functional components or custom hooks. React advises us not to use React hooks inside regular JS functions. The thought process behind this is that if we use React hooks inside normal JS functions, there is a chance for them to get "hidden" inside the call stack. Especially in a large codebase, it would be impossible to go through each and every function to see where React hooks have been used.
The thought process is the same in this case as well. It would be simpler for us to determine where React hooks have been used if we prefixed our custom hook names with "use".
So, the name of your custom hook should look like this
useMyCustomHook() useOnlineStatus() useCommentFilter()
How to write React Custom Hooks?
I've created a simple React hook to check if a given player is retired or not.
useRetiredStatus.js
import {useEffect, useState} from "react"; const useRetiredStatus = (player) => { const [isRetired, setIsRetired] = useState(null); useEffect(() => { //Assumption: The age of retirement for cricket is 40 yrs player?.age > 40 ? setIsRetired(true) : setIsRetired(false) }) return isRetired; } export default useRetiredStatus;
App.js
import React, {useEffect, useState} from 'react'; import useRetiredStatus from "./useRetiredStatus"; const players = [ {name: "Kumar Sangakkara", age: 44}, {name: "Angelo Mathews", age: 35}, {name: "Rohit Sharma", age: 35}, {name: "Mahela Jayawardene", age: 45}, {name: "David Miller ", age: 33}, ] function App() { const [player, setPlayer] = useState(players[2]); const retiredStatus = useRetiredStatus(player); return ( <> {`Dear Cricket Fans, ${player.name} is ${retiredStatus ? 'retired' : 'still playing the game'}`} </> ); } export default App;
Output
With React Custom Hooks, there are no limitations. We can change input and output variables into anything we want just like in a regular function. With this knowledge, you will be able to create custom hooks for all the unique requirements in your projects.
Can't I just use a JS function, instead of creating a custom hook?
You can use a JS function if your code does not make use of React hooks.
If the code contains React hooks, you should create a custom hook so that your code aligns with React's rules of hooks
Conclusion
Learning how to make use of React custom hooks will make your code look more cleaner and more readable. I hope you will be able to implement React custom hooks in your next project.
Thank you for reading the article. Hope you learned something valuable today. Until next time, take care guys.

Just a heads up that you can add highlighting to the code blocks if you'd like. Just change:

More details in our editor guide!
Hi Luke, Thanks for the heads up. I didn't know about that until you told me. I've updated the code snippets accordingly. Thanks for the support ❤️✌️
Custom Hooks really increase the power and flexibility for React applications. I'm trying to use them as much as possible now.

NAME
tkill, tgkill - send a signal to a thread
SYNOPSIS
#include <signal.h> /* Definition of SIG* constants */ #include <sys/syscall.h> /* Definition of SYS_* constants */ #include <unistd.h>
int syscall(SYS_tkill, pid_t tid, int sig);
#include <signal.h>
int tgkill(pid_t tgid, pid_t tid, int sig);
Note: glibc provides no wrapper for tkill(), necessitating the use of syscall(2).
DESCRIPTION.
RETURN VALUE
On success, zero is returned. On error, -1 is returned, and errno is set to indicate the error.
ERRORS
- EAGAIN
-.
Before glibc 2.30, there was also no wrapper function for tgkill().

QtQml.qtqml-typesystem-topic
The types which may be used in the definition of an object hierarchy in a QML document can come from various sources. They may be:
- provided natively by the QML language
- registered via C++ by QML modules
- provided as QML documents by QML modules
Furthermore, application developers can provide their own types, either by registering C++ types directly, or by defining reusable components in QML documents which can then be imported.
Wherever the type definitions come from, the engine will enforce type-safety for properties and instances of those types.
Basic Types
The QML language has built-in support for various primitive types including integers, double-precision floating point numbers, strings, and boolean values. Objects may have properties of these types, and values of these types may be passed as arguments to methods of objects.
See the QML Basic Types documentation for more information about basic types.
JavaScript Types
JavaScript objects and arrays are supported by the QML engine. Any standard JavaScript type can be created and stored using the generic var type.
For example, the standard
Date and
Array types are available, as below:
import QtQuick 2.0 Item { property var theArray: new Array() property var theDate: new Date() Component.onCompleted: { for (var i = 0; i < 10; i++) theArray.push("Item " + i) console.log("There are", theArray.length, "items in the array") console.log("The time is", theDate.toUTCString()) } }
See JavaScript Expressions in QML Documents for more details.
QML Object Types
A QML object type is a type from which a QML object can be instantiated. QML object types are derived from QtObject, and are provided by QML modules. Applications can import these modules to use the object types they provide. The
QtQuick module provides the most common object types needed to create user interfaces in QML.
Finally, every QML document implicitly defines a QML object type, which can be re-used in other QML documents. See the documentation about object types in the QML type system for in-depth information about object types. | https://phone.docs.ubuntu.com/en/apps/api-qml-current/QtQml.qtqml-typesystem-topic | CC-MAIN-2020-45 | refinedweb | 339 | 56.66 |
Creating a tree-type app
In this tutorial we will create an application that implements a 'tree' entity type hierarchy, consisting of two entity
types (with parent-child relation). The child entity type allows the user to click on a map to define a
GeoPoint. The
parent entity type collects the locations on each child entity and shows them together on a single map, making use of
the API.
For more examples of 'tree' type applications, please visit the sample apps
A template 'tree' type app can be generated using the CLI. We will use this template app as a starting point for the
tutorial. Run the following command (replace
tree-tutorial with the folder name of your choice):
viktor-cli create-app --app-type tree tree-tutorial
Navigate to the newly created folder, run the
install command from within the folder to install the app and its
dependencies,
clear any previous saved local database, and run
start to start to app:
viktor-cli install
viktor-cli clear
viktor-cli start
Login to the app in your browser to verify that the app is installed and running as expected. You will be redirected to the app's dashboard.
If you see the "Workspaces" menu upon logging in, click the "Open" button on the "Development" workspace. After opening, you will be redirected to the app's dashboard.
The tree-type app generated by the CLI consists of a top folder, called "My Folder", shown in the sidebar on the left side of the screen.
Click "My Folder" to enter the folder. Now, let's add a new object by clicking the + (create new object) button on the right side of the screen. You'll now see a menu where you can add a new object:
Create a new object of type "My Entity Type"
Provide a name for the new object and click "Create and open", to create the new object and automatically navigate to the object's editor (it should be empty). From here, you can navigate back to "My Folder" in a few different ways:
By clicking the back button in the top right side of the screen:
By clicking the menu button in the top left corner of the screen. This will extend (or collapse) the side menu. You can expand "My Folder" to see all containing objects, or click on it:
By clicking the breadcrumbs at the top of the screen:
Delete the created entity afterwards.
Folder structure
The app has the following folder structure:
tree-tutorial
├── app
│ ├── my_entity_type
│ │ ├── __init__.py
│ │ └── controller.py
│ ├── my_folder
│ │ ├── __init__.py
│ │ └── controller.py
│ └── __init__.py
├── CHANGELOG.md
├── README.md
├── requirements.txt
├── tests
│ └── __init__.py
└── viktor.config.toml
Note that the app type ('tree') has been defined in
viktor.config.toml:
app_type = 'tree'
To keep things simple, we will stick to the current entity type and corresponding folder names within this tutorial.
Defining the GeoPoint (child)
Let's modify
MyEntityType so that the user can define a
GeoPoint on a map. Open
app/my_entity_type/controller.py
and replace it with the following code:
from viktor import ViktorControllerfrom viktor.parametrization import ViktorParametrization, GeoPointFieldfrom viktor.views import MapView, MapResult, MapPointclass Parametrization(ViktorParametrization): geo_point = GeoPointField("Select point")class Controller(ViktorController): label = 'My geo-point' parametrization = Parametrization @MapView("Map", duration_guess=1) def map_view(self, params, **kwargs): features = [] if params.geo_point: features.append(MapPoint.from_geo_point(params.geo_point)) return MapResult(features)
In your browser, open "My Folder" and create a few entities of type "My geo-point". Don't forget to select a point on the map for each of them and save (including the entity created at the start of this tutorial, if you did not delete it before).
Defining the Overview (parent)
To show all the geo-points we just created, let's modify
MyFolder to iterate over all its children and obtain the
point from the params for each of them. Open
app/my_folder/controller.py and replace it with the following code:
from viktor import ViktorControllerfrom viktor.api_v1 import APIfrom viktor.views import MapView, MapResult, MapPointclass Controller(ViktorController): label = 'Overview' children = ['MyEntityType'] show_children_as = 'Table' @MapView("Map", duration_guess=1) def map_view(self, params, entity_id, **kwargs): features = [] for child in API().get_entity(entity_id).children(): point = child.last_saved_params.geo_point if point: features.append(MapPoint.from_geo_point(point)) return MapResult(features)
In your browser, open the editor of "My Folder". Within the "Map" view, click the 3 dots and select "Center map", to fit all objects within the view. You should now be able to see all your previously created geo-points. | https://docs.viktor.ai/docs/create-apps/tree-apps/tree-app-tutorial/ | CC-MAIN-2022-40 | refinedweb | 752 | 52.39 |

- Two more classes I’m looking into taking, both Python.
- Euler #4
- Gave up looking for a more complex solution and just brute forced it assuming the runtime would still be sufficiently small.
- Hand-written notes and logic. Needed a function just to reverse the integer and test if the same.
- Store largest value in a variable.
- Once done just print whatever value was found to be the largest.
- My code here:
#include <math.h> #include <stdio.h> #include <string.h> #include <stdlib.h> #include <stdbool.h> bool isPalindrome(int num); int main(void) { int max = 0; int num; for (int i = 999; i >= 100; i--) { for (int j = i; j >= 100; j--) { num = i*j; if (isPalindrome(num) && num > max) { max = num; } } } printf("%i\n", max); } bool isPalindrome(int num) { int reverse = 0; int n = num; while (n != 0) { reverse *= 10; reverse += n%10; n /= 10; } if (reverse == num) return true; else return false; }

- Forgot to mention the new book I got: A Mind For Numbers.
- Finished The Checklist Manifesto. How can I incorporate this into development? Unsure, but I am sure it will help with any type of team environment. Perhaps a list of steps to do before I tackle any problem?
- I got into the Rmotr course! Now to decide if I am capable of doing it. I don’t have much time to decide (Monday the 15th).
- I missed the questions on OOP in the application, since I’ve never done it (and it’s not a topic covered in CS50). Will I be able to learn enough about it in time to be comfortable in the course? I was initially rejected because of it, but in asking about the course and application that was overridden since I guess I showed some kind of persistence.
- I asked the guys for resources I could use to learn OOP as well.
- Also I am going to try and set up a call with them so I can really make sure this is a good fit for me and I won’t be starting at -1 when everyone else is at 11. I am willing to work hard and get it done though. Won’t say I’m not nervous though.
August 13, 2016
- Call with Santiago went very well (one of the founders of Rmotr.com)
- I felt very good and confident about the course during and after the call.
- Santiago wanted me to just be comfortable about my decision.
- So my current plan is to finish CS50 and learn OOP and some basic Python before the next session which starts October 10th.
- Start Oct 10 and commit 30 hours a week.
- There is a live OOP class Aug 29th with Rmotr that I can drop-in on, and I will.
- Decorators course video:
- Examples of some projects covered in the course Santiago sent to me:
August 14, 2016
- Python resources to read:
- A Byte of Python
- Automate the Boring Stuff
- The Hitchhiker’s Guide to Python
- Python Practice Book
- Think Python: How to Think Like a Computer Scientist
- Dive Into Python 3
- Intermediate Python
- Python Cookbook
- Functional Programming in Python
- HackerRank has Project Euler built into it. I no longer really need to just do it through the IDE alone.
-
- Solved Problem 1 again. They changed it up a bit from the original question. It requires you to be able to put in any input number and now requires use of larger integer data types (unsigned long long).
- Also to cut down on the runtime (it would fail you for taking too long) you needed to know the formula for calculating the sum of the multiples of 3 and 5.
August 15, 2016
- “Many of my students have been asking questions lately about how to do technical interviews, so I've decided to write about my interviewing experiences. I will start by giving a number of anecdotes because they're interesting to everyone, but the later parts of this post are mainly targeted at prospective students who haven't done any software developer interviews before. “
-
- “I had an interview where the interviewer asked "What is your favourite language?". My head wasn't in the right place at the time, and I said "Latin", and I went on to describe why I think Latin is such an interesting language. He was of course talking about programming languages. I didn't get an offer.”
- Went to Panera after work and watched CS50 Week 5 lecture #2 and part of Week 6 lecture #1.
- Apparently Problem Set 5 will be the hardest one. Yay?
- How do I get skilled enough to work on open source projects?
- Mind expanding books
August 16,2016
- Finished Week 6 Lecture #1 video
- A tiny bit more on data structures like Binary Search Trees, Hash Tables and Tries
- Mostly focused on how the web works with protocols, ports, packets, etc gearing up to learn HTML and CSS.
August 17, 2016
- CS50 Week 6: Section Videos
- Stack (Data Structure)
- Last in, first out (LIFO)
- Can use arrays or linked lists
- Push onto the stack
- Pop off the stack
- Queue
- FIFO structure
- Very similar to Stacks above
- Array or Linked List
- Enqueue (add to END) or Dequeue (remove elements from the FRONT)
- It acts just like any other line
- Size of queue plus the front of the queue is where you put the next element when enqueuing something.
- To wrap around when you hit the end of the array size you can modulo against the size of the array.
- Linked list based queues are just a doubly linked like that keeps track of the head and tail of the list only.
- I’m excited to get into these data structures finally when it comes to coding them. I can finally see where I can finally touch some things developers do daily (even if it’s the slightest of touches).
- PSET 5 Walkthrough for reference later:

Adobe Flex is becoming a popular choice for generating the client side of enterprise Java applications. In this first of two articles, Dustin Marx demonstrates how Flex can help you deliver highly interactive user interfaces that access your Java EE application's enterprise logic. Get a hands-on introduction to perfecting a simple Flex client, then enable it to communicate with your Java EE server. Level: Beginner
Flex 3 gives you another choice for building browser-based UIs for your Java EE applications. If you haven't yet discovered how simple it is to add rich clients to enterprise Java applications with Flex, this article could serve as your point of entry. You'll find out what benefits Flex brings to the table, how to create application layouts using Flex's XML grammar, and how to make your Flex client work with a Java EE application.
Java developers adopting Flex
We know that some Java developers are resistant to Flex as a front-end technology for Java EE, but there's a strong argument for giving Flex a chance. Author Dustin Marx discusses the factors driving Flex adoption in the Java community in a sidebar to this hands-on article.
Before I ask you to install Flex and start putting together a sample application, let's consider the advantages of using Flex as a client-side technology. Flex offers advantages specific to Java developers and some that are more general. We'll look at both.
Why choose Flex?
Adopting a new technology means embracing a learning curve, which can take some convincing. Here are some general advantages to using Flex:
- You can write Flex code once and run it in any Web browser for which a Flash Player plugin exists. None of the browser-detection or object-detection code typical of JavaScript or Ajax applications is required.
- The target runtime (Flash Player 9 or later) is installed on more than 95 percent of Web browsers worldwide.
- Flex is based on standards. Its scripting language (ActionScript 3.0) has roots in ECMAScript (the same specification implemented by JavaScript), and its layout language is a specific XML grammar called MXML. Familiarity with the underlying standards can help you learn Flex with relative ease.
- Flex has a refreshingly simple mechanism for binding the property of one object in a Flex application to the property of another object in Flex. This addictive feature is commonly referred to as property binding. (JSR 295: Beans Binding is intended to add this feature to the Java language, but it won't be included in Java SE 7.)
- You can associate the Flex-based front-end with any back-end technology using techniques that promote loose coupling. Flex provides built-in support for communication with back-ends via both traditional HTTP and SOAP-based Web services.
- Flex provides a rich set of components, Flash effects (including animation, video, and audio), and accessibility features that make it easy to add richness and highly fluid experiences to a Web application.
Flex for Java developers
General benefits might be enough to attract you to Flex, but there are others that are mostly or entirely aimed at Java developers.
One such benefit is the striking similarity between Java and ActionScript 3.0 in language features, concepts, and syntax. The languages use similar conditional statements, looping syntax, and even coding conventions. (It's arguable that ActionScript is more like Java than JavaFX Script.) Flex's Javadoc-like ASDoc documentation-generation tool uses the same comment syntax that you use in Java to generate documentation. ActionScript's packaging structure is related to directory structure in exactly the same way that Java approaches packages and directories.
ActionScript 3 also provides class-based object-oriented features (such as classes in the Java sense, inheritance, and interfaces) and static typing. These additions to what most of us are used to in JavaScript make learning and using ActionScript easier. (ActionScript still makes dynamic typing and prototype-based inheritance available for situations when you want or need those features of traditional JavaScript.)
Flex's ability to communicate with a Java EE back-end using HTTP or SOAP-based Web services is highly useful, but you're not limited to those communication approaches. Blaze DS -- a separate, open source product from Adobe -- gives you even greater flexibility for communicating between a Flex front-end and a Java EE back-end. BlazeDS lets you use JMS for communication and allows you to use object remoting with Java. BlazeDS also adds potential performance benefits because it uses the binary AMF3 format for faster communication than is normally experienced with XML.
A third-party open source product called GraniteDS offers even more choices for applying a Flex-based front-end to a Java EE application. GraniteDS offers support for the AMF3 binary format and also some features not available with BlazeDS. For example, GraniteDS offers tools and service frameworks for more easily integrating Flex with back-ends based on EJB 3, the Spring Framework, Guice, or Seam.
In discussing Flex so far, I've repeatedly used the words simple and easy. But don't just take my word for it. The best way to understand how simple and easy Flex basics are is to try them out for yourself. In the next sections you'll implement a sample application, refactor it to add features and reduce boilerplate code, and then establish communication between your new, Flex-based client and a Java servlet.
Acquiring and installing Flex
This article's examples use the Flex 3.2 SDK. If you want to build and run the examples, download the Flex SDK (including the command-line compiler and debugger). A single ZIP file contains the Flex SDK for multiple platforms.
Unzip the file into an obvious location, such as
C:\flex_sdk_3_2. For convenience, add the location of the Flex SDK
bin directory in the path so that the command-line tools can be run from any directory. I like to create a
FLEX_HOME environment variable that points at the Flex SDK location and then add
$FLEX_HOME/bin or
%FLEX_HOME%\bin to the
PATH. You can verify a correct installation of Flex by running the command
mxmlc -version, as shown in Figure 1.
Although it's not required to build and run the examples, you might be interested in downloading FlexBuilder 3, which is available at no cost for a trial period. FlexBuilder lets you use any text editor (such as JEdit or vim) or Java IDE (such as NetBeans or Eclipse) to write and maintain MXML and ActionScript files. Aptana Studio and Spket IDE include specific support for editing Flex-related files.
MXML: Flex layout with XML
Flex uses MXML for defining a Flex application's layout. Flex layout files are typically named with a
.mxml extension. MXML code must be well-formed XML and use XML namespaces. The example in Listing 1 demonstrates a simple but completely functional Flex application, written entirely with MXML, that displays a list of selected JavaWorld articles.
Listing 1. Static MXML example
<?xml version="1.0" encoding="UTF-8" ?> <mx:Application xmlns: <mx:Panel <mx:Label <mx:Grid> <mx:GridRow> <mx:GridItem> <mx:Label </mx:GridItem> Item> <mx:Label </mx:GridItem> </mx:GridRow> </mx:Grid> </mx:Panel> </mx:Application>
Because this example is static, it doesn't show off many of Flex's and Flash's advantages. However, it serves as a good introduction to MXML.
All of the code in Listing 1 is well-formed XML. Most of the XML lines in Listing 1 are related to the same lines of code (repeating
GridRow elements with nested
GridItem and
Label elements). They are used to define a static display grid with the
Grid component and its
GridRow and
GridItem sub-elements. The use of
<Grid>,
<GridRow>, and
<GridItem> organize and present data in a manner similar to how HTML table elements
<table>,
<tr>, and
<td>, respectively, are often used.
This first MXML example also demonstrates the
<mx:application> root tag used in all MXML applications. This tag includes an explicit width and height for the Flex application. The
mx prefix is associated with the Flex XML namespace as part of this root element.
You'll use the Flex command-line compiler,
mxmlc, to compile this article's examples. The Flex defaults (defined in the
flex-config.xml file) are sufficient for the examples' needs, making compilation with
mxmlc easy. Assuming the first MXML listing is saved in a file named
Example1.mxml, you compile it with this command:
mxmlc Example1.mxml
In accordance with the default settings, this MXML file is compiled into an SWF file, called
Example1.swf, that's placed in the same directory as the MXML file it was generated from. You can execute the SWF file by opening it in a Web browser or by simply entering the entire filename at the command line. The rendered SWF file looks something like Figure 2.

send email via new API with additional data
Hi,
Follow is my code to send email:
@api.multi
def mailmessage(self):
vals ={}
domain = [('name','like','EAR Activation Request')]
template = self.env['email.template'].search(domain, limit=1)
template = template[0]
print(template.email_to)
template.send_mail(self.id, True)
return True
My template is getting all the data correctly from model. However, I need to pass a dynamic data to the template before sending email. Be it email_to or ip_address. Can someone guide me how can I pass these two variables on runtime in my python code before send_mail function so the template pick them?
Thanks
Hi Alex below i am posting the code for new and simple way for doing this task
please use self.env.ref instead of self.env['email.template'].search(domain, limit=1)
mytemplate_obj = self.env.ref('my_module.my_mail_template', False)
here the mytemplate_obj is the object of email.template , it's mean it's a active record .
Now You can change/set the field value (email_from,subject,email_to)of this object simply and call the send_mail.
Hope this may help you.

A Rookie Guide to Getting Started with Backtesting in Python!
6 min read
Every Algorithmic trading rookie starts to wonder what Backtesting is and how it is implemented, yet many people ignore it based on their individual biases. But let me tell you frankly, it is a crucial step in building your algo trading robot.
To put it simply, your idea or strategy can be great in your head, but data never lies, and Backtesting is merely getting an indication as to whether your system will likely work or not.
To give you another example, think about the time when you have to decide which Mutual Fund or PMS service to invest in; you will always look at 3-Year, 5-Year Returns to arrive at a decision simply because data speaks for itself and "Sab Mutual Funds Sahi Nahi Hai"
Let's start Learning the Backtesting framework by creating and backtesting a simple strategy. We will be demonstrating a straightforward strategy to give a notion and introduce the library; the real-world strategy is much more complex. It needs various other factors to be considered, but the article is aimed at beginners.
Our sample strategy
- Quantity = 100
- Start Cash = 1,00,000
- Commission = 0.2%
- Position = Long
- Frequency = Daily
- Start Date = 1st Oct, 2021
- End Date = 15th Nov, 2021
- Buy Condition: When 21 RSI crosses above 30 and 50 SMA crosses above 100 SMA
- Sell Condition: When 21 RSI crosses below 70
While there are various open-source Python backtesting libraries, we have chosen
backtrader for this article. Every library has its pros and cons; if you want to check out some more options, we wrote this article a while back; check it out.
-> Installing backtrader -
pip install backtrader
-> Installing Yahoo Finance for Getting Data -
pip install yfinance
yfinance needs no introduction in the algo-trading world; everyone starts from this library and probably one of the most straightforward libraries to download global stock market data. We will be uploading our data in this example, but we want to let you know that
yfinance is also a worthy option.
-> Now let's import the Libraries-
import backtrader as bt import yfinance as yf from datetime import datetime
-> Creating class where we will define our strategy -
class firstStrategy(bt.Strategy):) def next(self): if not self.position: if self.rsi > 30 and self.fast_sma > self.slow_sma: # when rsi > 30 and fast_sma cuts slow_sma self.buy(size=100) # buying 100 quantities else: if self.rsi < 70: # when rsi is below 70 line self.sell(size=100) # selling 100 quantities
-> Now let's look at each function in Class
firstStrategy separately-
def __init__(self))
In this Function, we define the required elements for our strategy -
self.rsi contains our rsi indicator built on close data, and it's period = 21 days.
self.fast_sma - It is the Simple Moving Average indicator with 50 days period.
self.slow_sma - It is the Simple Moving Average indicator with 100 days period.
self.crossup - It is when 50 days(fast SMA)
cross above 100 days(slow SMA).
-> Now let's look at the other function in class
firstStrategy -
def next(self): if not self.position: # BUYING Condition if self.rsi > 30 and self.fast_sma > self.slow_sma: # when rsi > 30 and fast_sma cuts slow_sma self.buy(size=100) # buying 100 quantities of equity else: # SELLING Condition if self.rsi < 70: # when rsi is below 70 line self.sell(size=100) # selling 100 quantities of equity
In the above function, we create our strategy from the variable we created in the
init function.
If we have not taken a position we will buy 100 stocks based on the condition in our strategy and similarly if the position is already taken we will sell 100 stocks the stocks based on the condition provided.
-> Now, we have created our strategy for Backtesting. Let's look at other requirements for Backtesting the strategy.
-> Variable for our starting cash
startcash = 100000
-> Create an instance of cerebro
cerebro is the brain of
backtrader library.
cerebro = bt.Cerebro() # It is the main class in backtrader.
To read more about Cerebro, Click here.
-> Adding our strategy
cerebro.addstrategy(firstStrategy) # adding strategy in Cerebro engine
-> Uploading the CSV file containing OHCLV data for backtesting in Google Colab.
from google.colab import files uploaded = files.upload()
Note 1:- In the above code, we add CSV files from our local machine.
Note 2:- You can skip the above code block when running on the local machine.
We have the sample data for
HDFCBANK.NS which you can download from here if needed.
-> Getting data for backtesting our strategy
# Get HDFCBANK data from Yahoo Finance. # ----- Use below code to fetch data from Yahoo Finance CSV ------- data = bt.feeds.YahooFinanceCSVData( dataname="HDFCBANK.NS.csv", fromdate=datetime(2020,11,1), todate =datetime(2021,11,1))
Note 3:- The field
dataname should be replaced with the data file path if you are running this on the local machine.
-> Add the data to Cerebro
cerebro.adddata(data)
-> Setting the broker commission to 0.2%
cerebro.broker.setcommission(commission=0.002)
-> Setting our desired cash start
cerebro.broker.setcash(startcash)
-> Run over everything
cerebro.run()
-> Get final portfolio Value and pnl and printing them
portvalue = cerebro.broker.getvalue() pnl = portvalue - startcash # Printing out the final result print('Final Portfolio Value: ${}'.format(portvalue)) print('P/L: ${}'.format(pnl))
Output ->
Note:- The currency in the output above is in USD. We can convert the currency to INR by using appropriate conversion rates.
-> There are various strategies, methods to analyze our output. We will discuss them in our upcoming blogs. there.! | https://tradewithpython.com/a-rookie-guide-to-getting-started-with-backtesting-in-python | CC-MAIN-2022-21 | refinedweb | 933 | 56.35 |
CTxMemPool stores valid-according-to-the-current-best-chain transactions that may be included in the next block. More...
#include <txmempool.h>
CTxMemPool stores valid-according-to-the-current-best-chain transactions that may be included in the next block.
Transactions are added when they are seen on the network (or created by the local node), but not all transactions seen are added to the pool. For example, the following new transactions will not be added to the mempool:
CTxMemPool::mapTx, and CTxMemPoolEntry bookkeeping:
mapTx is a boost::multi_index that sorts the mempool on 5 criteria:
Note: the term "descendant" refers to in-mempool transactions that depend on this one, while "ancestor" refers to in-mempool transactions that a given transaction depends on.
In order for the feerate sort to remain correct, we must update transactions in the mempool when new descendants arrive. To facilitate this, we track the set of in-mempool direct parents and direct children in mapLinks. Within each CTxMemPoolEntry, we track the size and fees of all descendants.
Usually when a new transaction is added to the mempool, it has no in-mempool children (because any such children would be an orphan). So in addUnchecked(), we:
When a transaction is removed from the mempool, we must:
These happen in UpdateForRemoveFromMempool(). (Note that when removing a transaction along with its descendants, we must calculate that set of transactions to be removed before doing the removal, or else the mempool can be in an inconsistent state where it's impossible to walk the ancestors of a transaction.)
In the event of a reorg, the assumption that a newly added tx has no in-mempool children is false. In particular, the mempool is in an inconsistent state while new transactions are being added, because there may be descendant transactions of a tx coming from a disconnected block that are unreachable from just looking at transactions in the mempool (the linking transactions may also be in the disconnected block, waiting to be added). Because of this, there's not much benefit in trying to search for in-mempool children in addUnchecked(). Instead, in the special case of transactions being added from a disconnected block, we require the caller to clean up the state, to account for in-mempool, out-of-block descendants for all the in-block transactions by calling UpdateTransactionsFromBlock(). Note that until this is called, the mempool state is not consistent, and in particular mapLinks may not be correct (and therefore functions like CalculateMemPoolAncestors() and CalculateDescendants() that rely on them to walk the mempool are not generally safe to use).
Computational limits:
Updating all in-mempool ancestors of a newly added transaction can be slow, if no bound exists on how many in-mempool ancestors there may be. CalculateMemPoolAncestors() takes configurable limits that are designed to prevent these calculations from being too CPU intensive.

Calculate all in-mempool ancestors of a set of transactions not already in the mempool and check ancestor and descendant limits.
Heuristics are used to estimate the ancestor and descendant count of all entries if the package were to be added to the mempool. The limits are applied to the union of all package transactions. For example, if the package has 3 transactions and limitAncestorCount = 25, the union of all 3 sets of ancestors (including the transactions themselves) must be <= 22.

UpdateForDescendants is used by UpdateTransactionsFromBlock to update the descendants for a single transaction that has been added to the mempool but may have child transactions in the mempool, eg during a chain reorg.
setExclude is the set of descendant transactions in the mempool that must not be accounted for (because any descendants in setExclude were added to the mempool after the transaction being updated and hence their state is already reflected in the parent state).
cachedDescendants will be updated with the descendants of the transaction being updated, so that future invocations don't need to walk the same transaction again, if encountered in another transaction chain.
Definition at line 115 of file txmempool.cpp.
For each transaction being removed, update ancestors and any direct children.
If updateDescendants is true, then also update in-mempool descendants' ancestor state.

Definition at line 1098 of file txmempool.cpp.
When adding transactions from a disconnected block back to the mempool, new mempool entries may have children in the mempool (which is generally not the case when otherwise adding transactions).
UpdateTransactionsFromBlock() will find child transactions and update the descendant state for each transaction in vHashesToUpdate (excluding any child transactions present in vHashesToUpdate, which are already accounted for). Note: vHashesToUpdate should be the set of transactions from the disconnected block that have been accepted back into the mempool.
Definition at line 162 of file txmempool.cpp.
visited marks a CTxMemPoolEntry as having been traversed during the lifetime of the most recently created Epoch::Guard and returns false if we are the first visitor, true otherwise.
An Epoch::Guard must be held when visited is called or an assert will be triggered.
If sanity-checking is turned on, check makes sure the pool is consistent (does not contain two transactions that spend the same inputs, all inputs are in the mapNextTx array).
If sanity-checking is turned off, check does nothing.
Definition at line 582 of file txmempool.h.
This mutex needs to be locked when accessing
mapTx or other members that are guarded by it.
By design, it is guaranteed that:
cs_mainand
mempool.cswill give a view of mempool that is consistent with current chain tip (
ActiveChain()and
CoinsTip()) and is fully populated. Fully populated means that if the current active chain is missing transactions that were present in a previously active chain, all the missing transactions will have been re-added to the mempool and should be present if they meet size and consistency constraints.
mempool.cswithout
cs_mainwill give a view of a mempool consistent with some chain that was active since
cs_mainwas last locked, and that is fully populated as described above. It is ok for code that only needs to query or remove transactions from the mempool to lock just
mempool.cswithout
cs_main.
To provide these guarantees, it is necessary to lock both
cs_main and
mempool.cs whenever adding transactions to the mempool and whenever changing the chain tip. It's necessary to keep both mutexes locked until the mempool is consistent with the new chain tip and fully populated.

What's Your Function?
Pages: 1, 2
So before we play around with this code that we just read through, let's give it a whirl.
Up at the top of the window, in the toolbar, there is an icon that looks like this if you're running Project Builder:
And like this if you're running Xcode:
This is the "Build and Run" button, which will compile the project that you're working on (make the code into language the computer can execute), and then run the program you made. If you click this now, you will build and run the code contained in this project, which is just the main function we've examined. Do this now, and watch the computer execute the code, printing the message into the window (in Xcode, you have to go to the Debug menu and select Show Run Log to see the message). If you get an error, make sure that everything is copied exactly.
main
So that's what you can do without writing a single line of code. But we already have a few lines of code sitting around from our last lesson, so let's pull those out and give them a whirl. Delete the comment and the call to printf, and paste in our code. Now your main.c file should contain this:
printf
#include <stdio.h>
int main (int argc, const char * argv[]) {
/);
return 0;
}
And again, click the Build and Run button (remember that if you're in Xcode, you have to select Show Run Log from the Debug menu). Now, instead of "Hello, World!", what prints is "My favorite number is 8!" And you made it print that.
But what else can you make it do? We'll explore our boundaries a little bit by defining our own function. So below the main function, put the following snippet of code:
int integerForSeedValue(int seedNumber) {
//code goes here
}
This is another function definition, so called because it defines exactly what the function does. There are a few things to notice here, the first being that the name of the function follows the same style we use for variables: take all of the words that make up what you're describing, smash them together with each word capitalized, and make the first letter lowercase.
Notice also that our function has one argument, and that argument is described in the parentheses. Our code defines its type, which is an int, and we give it a name, seedNumber, which again follows our variable-naming scheme. Every time we want to call this function, we must pass one integer into it, or the compiler will complain and the program will crash.
int
seedNumber
Note where the curly brackets are placed. This method is the traditional C style, with the opening bracket on the same line as the function name. Objective-C uses this same style, but C++ puts the opening bracket on the next line, all alone. Since C ignores whitespace, both are perfectly legal, and since a lot of people use C++ a lot, they're more used to it down there on the next line. So don't be alarmed if you see it move around a bit.
Lastly, we're returning an integer, but we have no code that says what we're returning. This is obviously a problem, but before we fix our function up, let's hit the Build button and see what the Developer Tools think. We want to build and not run for right now, because our code is not correct, and we need to see how the Developer Tools inform us of this fact. The Build button looks like this in Project Builder:
And like this in Xcode:
When you hit the Build button, the project window moves around a bit to make it obvious it's doing something. In Project Builder, an area opens up to tell you about how the build is going. In Xcode, the Errors and Warnings item on the left will open up. In either case, you will see the message warning: control reaches end of non-void function.
What's this? It's a warning. Warnings tell you that while the compiler was trying to understand your code, something seemed a little odd, and it decided to tell you about it. This warning tells you that you have made a function whose definition claims the function returns a value (an int, in our case), but the function body doesn't ever return anything. That would be just fine in a void function (which we'll get to later), but it's a little odd here, so the compiler gives you a warning. An error is a more serious problem that means that your code cannot be compiled as written, and you need to fix the problem before you can run. Both show up in the same places, but warnings will allow you to run your program, although they often foretell errors that will crash your program at run time. Click on the text and the developer tools will helpfully take you to the offending piece of code. For now, it's obvious that our new function is the culprit, but in huge projects, this click-and-go is a lifesaver.
For now we have a simple fix to our problem. We simply add a line into our function, so it looks like this:
int integerForSeedValue(int seedNumber) {
//code goes here
return 0;
}
Click Build again, and you will see that the warning disappears. It is a good practice to write code that has neither warnings nor errors, and we will strive to do this as we complete more complex code.
But for now you may wonder about our little fix. Our function ignores the input we give it, doesn't do anything useful, and always returns the same thing. What is this, a Windows error dialog?
So let's spice up our function a little. Change the function to the following:
int integerForSeedValue(int seedNumber) {
return seedNumber - 3;
}
Now we're doing some work in our function, and we're returning something that changes, based on what we're given. We return the variable seedNumber, minus the constant 3. But you might be wondering how we can use the variable seedNumber without first issuing a variable declaration, and that is a very good question. The answer is that we did a variable definition, it's just not as visible as the others we have done. This definition is inside of the parentheses, in the argument list. There, when we note what arguments this function takes, we are also declaring these arguments to exist.
So now that we have a function, we need to call it. Up in our main function, replace the line
favoriteNumber = favoriteNumber + 2;
with the slightly altered line:
favoriteNumber = integerForSeedValue(favoriteNumber + 2);
Now we're calling our integerForSeedValue function from our main function. When the computer executes that line of code, it will look into our integerForSeedValue function and run all of the code in its code block before moving on to the next line of code in main. Note that while the computer is executing the lines in integerForSeedValue, the variable seedNumber will have the evaluated value of favoriteNumber + 2, which is 8. So integerForSeedValue will return 8-3, or 5. Let's build our program and see. Hit the Build button, to make sure we don't have any warnings or errors.
integerForSeedValue
favoriteNumber + 2
8-3
5
Well, what do you know? We do. The warning we got this time is warning: implicit declaration of function `integerForSeedValue'. What does that mean? Well, we know what a variable declaration is, and we know that we can't use variables until we declare them. And if we click on this warning, it takes us to where we're using our function, so it's a pretty logical step to think that functions need to be declared before use, too, and that's exactly right.
So we add in one line above main, to declare our function. Now our file looks like this:
#include <stdio.h>
int integerForSeedValue(int seedNumber);! */
printf("My favorite number is %d!", favoriteNumber);
return 0;
}
int integerForSeedValue(int seedNumber) {
return seedNumber - 3;
}
Looks familiar, doesn't it? What we've done is take the function, knock it's block off, and present it here with a semicolon. That is enough for the compiler; this simple line is the function declaration we needed, and another Build confirms it when the compiler doesn't complain. Run the program, and you see that our favorite number is now 5, just like it should be!
Wow, we've made some progress in this lesson! We learned about the tools we'll need to use every day we're developing, we compiled and ran "Hello World!", we took a few lines of code and made it into a program, we learned how to recognize, implement, declare, and call functions, and we learned how to get information from the Developer Tools about problems with our code, and fix them before they're problems with our programs.
But we still have a long ways to go. Next time, we'll dive into
flow control, which affect the way our code gets executed, so we
can do more complex things than the "list of things to do" approach we
have been taking. That will give us a lot of the tools we need to make
more complex programs with the knowledge we've gained.

I like the idea of jasmine specs, makes them so much nicer / rspec-ish.
create something like rake compile_all_coffee and run it on the ci before tests, so you do not have to check in the compiled source.
Also you only need guard if you do something auto-test-ish, another idea wold be to have the compile step taking place in a task you perpend to jasmine
May 11, 2011 at 9:28 pm
Switch to node.js and express! It can do .coffee compilation on the fly and serve up the corresponding .js code. Or in rails, you could add the equivalent logic to test the request path for .js, look at the filesystem for a matching .coffee and compile it on the fly. This could go in the rescue block where your 404 page might ultimately be rendered.

@grosser – Right before I went to bed I came up with the rake task idea for compiling coffeescript…stay tuned for an add on post about that.
@peter – Using node is another great idea. I’ll poke around and see what I can figure out. Thanks!
May 12, 2011 at 5:01 am
I’m currently using the rack-asset-compiler gem to compile jasmine specs and app code.
The CoffeeScript compilation step is done inside of Rack middleware, so there’s no need to run a rake task or use a process to watch the CoffeeScript files for changes. The middleware uses the If-Modified-Since header to make sure CoffeeScript is only compiled when it changes.
I have a sample jasmine_config.rb here:
May 12, 2011 at 10:01 am
Hey Mike, nice post! I stumbled upon it when trying to figure out how to integrate jasmine into my node app :x
July 9, 2011 at 8:59 pm
I have one newbie question. Is there a way to test anything not global? In this example, it’s testing the global Math prototype. but if I create a new coffeescript class, I will have to attach it to the window. For example, class window.Picture….
Is it the approach you are taking too? If not, what will you recommend? Thanks
July 15, 2011 at 3:28 pm
You can check jasminerice gem
also
July 17, 2011 at 2:06 am
@alf The approach I take is to set up a namespace for my application and attach that to window and then I have all of my code attach to that namespace:
window.MyApp = {}
class MyApp.MyClass
foo: ->
alert(“Foo called”)
a = new MyApp.MyClass()
a.foo()
Hope this helps.

GanttTask Deadline
With the official Q2 2014 release of UI for WPF/SL you will have the option to use the Deadline property of the GanttTask and visualize an indicator showing whether the task is expired.
This help topic will describe the Deadline property in more details as well as how you could customize its behavior.
Overview
Setting the Deadline property of the GanttTask visualizes a vertical line showing the deadline for finishing the task as well as an indicator showing whether the task is on time or delayed.
Example 1 shows how the Deadline can be set.
var task = new GanttTask() { Start = new DateTime(2014, 6, 6), End = new DateTime(2014, 6, 8), Deadline = new DateTime(2014, 6, 9), Title = "Gantt Rendering" };
Dim task = New GanttTask() With { _ .Start = New DateTime(2014, 6, 6), _ .[End] = New DateTime(2014, 6, 8), _ .Deadline = New DateTime(2014, 6, 9), _ .Title = "Gantt Rendering" _ }
When the End time is before the set Deadline of the Task, the Indicator is in green color, however, as soon as you expand the task after the End, the Indicator is replaced with one that has red color.
Figure 1 shows how the Deadline and the Indicator are visualized in the Timeline part of the control.
Figure 1: Deadline and Indicator
Customization
There may be cases when you need to add different logic for marking tasks as expired. The default implementation is as soon as the End goes after the Deadline, the task is marked as delayed.
In order to change this behavior, you will need to create a custom GanttTask and override its CheckIsExpired method. Example 2 demonstrates how to override this method, so that the task is marked as expired only when its Start property goes after the set Deadline:
Example 2 shows how to override CheckIsExpired method.
public class CustomGanttTask : GanttTask { protected override bool CheckIsExpired() { return this.Deadline < this.Start; } }
Public Class CustomGanttTask Inherits GanttTask Protected Overrides Function CheckIsExpired() As Boolean Return Me.Deadline < Me.Start End Function End Class
Figure 2 and Figure 3 show the result:
Figure 2: Even if the End is after the Deadline, the task is not marked as expired.
Figure 3: As soon as the Start goes after the Deadline, the task is marked as delayed.

Kamozo
That's useful, but what if I wanted to animate a gif using the scene module only, with my own images? Would that be possible?
Kamozo
Oh, okay. It'd be cool if they were. Perhaps maybe in a future version.
I've tried splitting them, but I don't know how to make it continuously repeat.
Kamozo
Hi, I was wondering if the scene module supported gifs. I've tried using them in my own project but they are just a still image.
Here's some example code so you can see what I'm trying to do:
from scene import * class MyScene (Scene): def setup(self): self.background_color = 'midnightblue' self.ship = SpriteNode('ship.GIF') #Why won't it play? self.ship.position = self.size / 2 self.add_child(self.ship) run(MyScene())
Help would be appreciated, thanks.
Kamozo
Nevermind, I've figured it.
Thanks for all your help.
Kamozo
Oh yeah, I'm not sure how I didn't notice that.
Where does the code you've provided fit into mine?
Kamozo
Wow, thank you, that helps me a lot.

Building a dynamic JSON Request body with n objects in an array
Hello,
I have a use case that I'm trying to implement in SOATest and am running into a wall.
I have a Service1 that returns n number of Account objects. There are a varying amount of accounts that could be returned for a given request as that user may have more or less accounts than another.
I have a second service, Service2, that takes a structured request of n Account objects and AccountId is an integer that is required on all Accounts passed.
What I am attempting to do is extract AccountIds from the Service1 response and then build out a request to Service2 in a dynamic fashion. I have tried using a JSON Databank to extract the AccountIds from Service1 and then paramaterized that to the Service2 request but it just pastes ALL the AccountIds into a single AccountId field. Is there any way to dynamically create an array of objects using SOATest, in memory?
See below for samples.
Service1 Response:
{
"AccountSummaryList":[
{
"AccountId":"111111111",
"AccountType:"BLAHBLAH"
},
{
"AccountId":"22222",
"AccountType:"BLAHBLAH"
},
{.....}
]
}
Service2 Request:
{
"Accounts":[
{
"AccountId":111111,
"otherdetails":"blahblah"
},
{
"AccountId":222222,
"otherdetails":"blahblah"
}
]
}
I second this question!
Hi Beitliche,
There are possibly more elegant implementations, but off the top of my head I would use an XML data bank to extract all of the element values to a Writable data source.
Modify the Xpath to grab all values not just a single one.
Once written into a data source you can then use the
context.getValues("writable_name","column_name") method to move the values to an arraylist and then simply loop the values while adding the tags. You would then have your xml body.
This Example requires the use of a test suite variable. (Double click the test suite and navigate to then variable tab)
Example script:
import com.parasoft.api.*;
Now you can reference the variable "x" to get the values.
In your messaging client, switch to "literal mode"(otherwise the background encoding will change the '<' & '>') and reference the variable with ${variable_name} .
The scenario
Here is some general information.
It is common for to take elements/objects/arrays from a response and then reuse them in a subsequent request. Typically, you would do the following:
What I mention applies to both JSON and XML. For JSON, you would be using a JSON Data Bank and the Form JSON view. For XML, you would be using an XML Data Bank and the Form Input view.
Sometimes using the extraction as-is is desired. However, in some scenarios you want to transform the data in some way before reusing it. This could be accomplished using scripting (Extension Tool) or using XSL (XSLT Tool). Some simple transformations, like removing or appending values, can be applied by Data Bank itself by enabling the "Allow alteration" box under Options (collapsed by default).
Ramiro's response is one such example where scripting can be used to transform extracted values.
Hello,
Thank you for your responses.
@benken_parasoft I have tried the above and am not seeing the intended outcome.
Here is a sample of the response that I am extracting the AccountId values from:
From this response I have the following data bank/xpath setup. As you can see it's set in "AccountId, ####" format. Which I would expect to be able to use.
In the secondary request I am trying to build here is a sample of the form JSON (There will be other elements, I'm just trying to get this one working for now as a POC).
I have tried setting the Replacement at the Accounts, and Item[0] level (as those are the only two that allow it. I cannot add a replacement at the AccountId level). I receive the following error when attempting this.
Please advise if I am missing something but as far as I can tell SOATest does not natively support the use case for which I am trying. Short of coding up an extension to build this request I cannot see a path forward.
Thanks!
The steps I described are for extracting the entire array and then replacing the entire array element. If you want to do that then you would extract the value of the AccountSummaryList array and then replace the Accounts array in the subsequent test.
As mentioned, more steps or different steps would be required if you need to transform the contents of the array being extracted (change/add/remove values or rename things). As mentioned, this may have involve scripting or XSL. Ramiro gives one such example. Please note that if you follow Ramiro's example, he's not extracting the entire array but the contents to a Writable Data Source and using scripting to construct the desired result (which is a different approach than what I describe but also fine). | https://forums.parasoft.com/discussion/comment/8246/ | CC-MAIN-2018-13 | refinedweb | 808 | 62.68 |
Follow these steps to implement:
- Choose any element of the list to be the pivot.
- Divide all other elements (except the pivot) into two partitions.
- All elements less than the pivot must be in the first partition (lower half list).
- All elements greater than the pivot must be in the second partition (upper half list).
- Use recursion to sort both partitions.
- Join the first sorted partition, the pivot, and the second sorted partition
def qsort(list): if not list: return [] else: pivot = list[0] less = [x for x in list if x < pivot] more = [x for x in list[1:] if x >= pivot] return qsort(less) + [pivot] + qsort(more)
Example:
someList = [3, 1, 4, 1, 5, 9, 2, 6, 5, 3, 5, 8, 9, 7, 9, 3]
print qsort( someList )
[1, 1, 2, 3, 3, 3, 4, 5, 5, 5, 6, 7, 8, 9, 9, 9]
Enjoy the sort. | https://anothergisblog.blogspot.com/2012/05/quicksort-using-python.html | CC-MAIN-2018-05 | refinedweb | 149 | 64.04 |

In this tutorial, you will learn what is Java variable and how to work with it. Also, you will learn where variables are commonly used in Java programming.
A variable or Java.
In simple Words, it can Be defined as “Variable is the name of the reserved area allocated in memory.”.
Below given is valid examples of variable declaration and initialization in Java −
variable declaration and initialization'
Types of variables:
- local variable
- instance variable
- static variable
Local Java variable
- Local variables are declared in methods, constructors, or blocks.
- Local variables are created when the method, constructor or block is entered and the variable will be destroyed once it exits the method, constructor, or block.
- There is no default value for local variables, so local variables should be declared and an initial value should be assigned before the first use.
- Local variables are implemented at stack level internally.
- Access modifiers cannot be used for local variables.
- Local variables are visible only within the declared method, constructor, or block.
Program to find Age in Java
Here in this example,(); } }
Output
Puppy age is: 7
Error at the time of compilation in Java.(); } }
Output:
Test.java:4:variable number might not have been initialized age = age + 7; ^ 1 error
instance Java variable
- A variable that is declared inside the class but outside the method is called instance variable.
- It is not declared as static.
-.
Program to Print Name and Age in Java
static Java variable
- A variable that is declared as static is called static variable. It cannot be local.
- The static variable is created when the program starts and destroyed when the program stops.
- Visibility is similar to instance variables. However, most static variables are declared public since they must be available for users of the class.
- Static variables can be accessed by calling the class name ClassName.VariableName.
- There would only be one copy of each class variable per class, regardless of how many objects are created from it.
- Default values are same as an instance variable. For numbers, the default value is 0; for Booleans, it is false; and for object references, it is null. Values can be assigned during the declaration or within the constructor. Additionally, values can be assigned in special static initializer blocks.
- When declaring a class variable as public static final, then variable names (constants) are all in upper case. If the static variables are not public and final, the naming syntax is the same as instance and local variables.
Program to find Department Average Salary
import java.io.*; public class Employee { // salary variable is a private static variable private static double salary; // DEPARTMENT is a constant public static final String DEPARTMENT = "Development "; public static void main(String args[]) { salary = 2000; System.out.println(DEPARTMENT + "average salary:" + salary); } }
Output:
Development average salary:2000

from django.db import utils fails; import django.db.utils succeeds
Description
Here's a simple reproduction for 1.5.1:
import os
os.environ[ 'DJANGO_SETTINGS_MODULE' ] = 'sys'
sys.SECRET_KEY = 'foo'
import django.db.utils #works! (as expected)
from django.db import utils #fails! wtf?
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: cannot import name utils
Same problem occurs in 1.3.3.
This can manifest in a variety of ways:
File "/x/home16/eveljee/lib/python/site-packages/django/db/backends/sqlite3/base.py", line 14, in ?
from django.db import utils
TemplateSyntaxError: Caught ImportError while rendering: cannot import name utils
I have no theories as to what the underlying cause is; need someone more familiar with Django's internals.

Hi,
I can't reproduce the issue you're describing (I used your example with an added import sys at the top which I assume was missing).
The code you provided looks strange too: is sys really the name of your project? If so, that's not a very good name for a project since it clashes with a builtin python module.
I tried with django 1.5.1 and 1.3.3 as well as python 3 and none raise an ImportError.
I'm going to mark this as worksforme. Please re-open if you have some more information on how to reproduce this issue.
Thanks. | https://code.djangoproject.com/ticket/20295 | CC-MAIN-2015-32 | refinedweb | 278 | 67.65 |
