Right now it is all functioning, so that is pretty exciting. My goal though was to have the OpenID authentication take place it a popup window. This seems to be the default behavior when you using WebForms with the DNOA custom controls, but I haven't been able to figure it out in MVC.
I thought I was getting close with this:
var request = OpenIdRp.CreateRequest(id);
request.AddExtension(new UIRequest(Mode = UIModes.Popup));
But the Mode field of the UIRequest is read-only.
Does anybody know how to create a request that tells the OpenID provider to open a popup window?
Thanks for any help. So far I have been unable to track down any samples of this in action.

As <PERSON> mentioned, the newline character should be \n, not /n
str.strip() does not modify the string directly. It returns a copy of the modified string. So it should be Whole = Whole.strip('\n')
str.strip() remove leading and trailing characters. In your case, you wanted to remove the newline characters which are in the middle of the string. So you should use str.replace() instead, e.g. Whole = Whole.replace('\n', '')

I made an an example for you that does this:
pulic class SomeActivity extends Activity {

@Override
public boolean onTouchEvent(MotionEvent event) {
// Get the center location of the TextView.
int[] tv01pos = {(int) tv01.getX(), (int) tv01.getY()};

Log.d("position TV x", String.valueOf(tv01pos[0]));
Log.d("position TV y", String.valueOf(tv01pos[1]));
// Get the width and height of textView 01 for calculating the right and bottom boundaries.
int tv01Wide = tv01.getWidth();
int tv01High = tv01.getHeight();
// Get the location of the touch event, event may be of type Donw, Move, or Up.
// Keep in mind there are a LOT of these generated.
int[] touchPos = new int[2];
touchPos[0] = (int) event.getAxisValue(MotionEvent.AXIS_X);
touchPos[1] = (int) event.getAxisValue(MotionEvent.AXIS_Y);
// More debug logs.
Log.d("position Tch x", String.valueOf(touchPos[0]));
Log.d("position Tch y", String.valueOf(touchPos[1]));
// Check if the touch event is in the boundaries of TextView 01
if ( (touchPos[0] > tv01pos[0] ) &&
(touchPos[0] < tv01pos[0] + tv01Wide) &&
(touchPos[1] > tv01pos[1] ) &&
(touchPos[1] < tv01pos[1] + tv01High)) {

In the second question I'm asking clarification on a very odd behavior that I will first explain.
I've spent several days now messing around with animations trying to animate an AdapterViewFlipper as described above, mostly as a learning exercise. I have found that the methods available (inherited from AdapterViewAnimator are setInAnimatior() and setOutAnimatior(), both receive an ObjectAnimator parameter. ObjectAnimator as I understand (wrongly maybe?)
to only be able to animate one Property per XML tag or Java instantiation, (sometimes an x and y Property simultaneously). The documentation shows that typically ObjectAnimators are grouped into AnimatorSet objects which can be created cleanly in XML, my problem is getting these AnimatorSet objects to animate the view transition. I was nearly to the point of creating an extension of AdapterViewFlipper to try to solve this when something weird happened.
To explain, below is one of my original attempts to animate the flipping (I've simplified the code to a single flipping direction, the opposite direction is similar only differing in the XML "valueFrom" and "valueTo" values):
...
AnimatorSet inLeftSet;
AnimatorSet outLeftSet;
@Override // This is in a fragment
public View onCreateView(...) {
...
inLeftSet = (AnimatorSet) AnimatorInflater.loadAnimator(
this.getContext(),
R.animator.card_flip_left_in);
outLeftSet = (AnimatorSet) AnimatorInflater.loadAnimator(
this.getContext(),
R.animator.card_flip_left_out);
}
@Override
public void onClick(View v) {
switch (v.getId()) {
...
case (R.id.next_image):
outRightSet.setTarget(flipper.getCurrentView());
flipper.showNext();
inRightSet.setTarget(flipper.getCurrentView());
outRightSet.start();
inRightSet.start();
break;
...
}
And the corresponding XML files are:
card_flip_right_in.xml
<set xmlns:android="http://schemas.android.com/apk/res/android">
<objectAnimator
android:duration="0"
android:propertyName="alpha"
android:valueFrom="1.0"
android:valueTo="0.0"/>
<objectAnimator
android:duration="@integer/card_flip_time_full"
android:interpolator="@android:interpolator/accelerate_decelerate"
android:propertyName="rotationY"
android:valueFrom="180"
android:valueTo="
<objectAnimator
android:duration="1"
android:propertyName="alpha"
android:startOffset="@integer/card_flip_time_half"
android:valueFrom="0.0"
android:valueTo="1.0"/>
</set>
card_flip_right_out.xml
<set xmlns:android="http://schemas.android.com/apk/res/android">
<objectAnimator
android:duration="@integer/card_flip_time_full"
android:interpolator="@android:interpolator/accelerate_decelerate"
android:propertyName="rotationY"
android:valueFrom="0"
android:valueTo="-180"/>
<objectAnimator
android:duration="1"
android:propertyName="alpha"
android:startOffset="@integer/card_flip_time_half"
android:valueFrom="1.0"
android:valueTo="0.0"/>
</set>
This did not produce the desired result (example of the desired animation can be viewed from this Tutorial). Rather the initial ImageView spun completely around before flickering and finally displaying the next ImageView suddenly and without animation.
Here comes the weird part, I created this next snippet inside the onClick() for rotating right (next image), and it completely didn't work the ImageView just flashed to the next with no animation, BUT, when I accidentally clicked previous image (which has the same code as above) it animated perfectly!?!?
Iterator<Animator> iterator = outRightSet.getChildAnimations().iterator();
while (iterator.hasNext()) {
flipper.setOutAnimation((ObjectAnimator) iterator.next());
iterator.remove();
}
iterator = inRightSet.getChildAnimations().iterator();
while (iterator.hasNext()) {
flipper.setInAnimation((ObjectAnimator) iterator.next());
iterator.remove();
}
There was originally more code as it was a test, but through trial and error I nailed down the part of the code that makes it work to the above snippet. What is stranger than anything is that I moved this out of the onClick() to the onCreateView() Override, right after the AnimatorSet objects are inflated and it still worked. Needing to only execute once for all animations to work as intended in both directions, rotating left and rotating right.
Though I'm thrilled that it works, I'm bothered that it works, because I don't know why that it works. My original intention with the test code was to try to pass each ObjectAnimator from the AnimatorSet individually to the AdapterViewFlipper through setOutAnimation() and setInAnimation() methods, a test that I wasn't sure would do anything (I was having a hard time finding adequate usage explanations in the documentation) and now I would really like to understand what is going on, and if there is a simpler, more proper, or easier-for-others-who-may-need-to-work-on-my-code way to achieve this same result.
Thanks in advance for any help.

String extensions is generally a bad idea because string is such a common type.
Conversion code can be written more defensively. Use TryParse instead of Parse and if TryParse fails then handle that by throwing an Exception, or some other error handling.
Throwing a generic exception with no message is not great.

Hoping that Apple will eventually sort it out, but in the meantime, this is the nicest way possible:
Place one custom segue instead of Show Detail
In perform method of your custom segue have something like:
- (void)perform
{
MasterViewController *source = self.sourceViewController;
AppDelegate *appDelegate = [UIApplication sharedApplication].delegate;
UISplitViewController *splitViewController = appDelegate.splitViewController;
if ([splitViewController.viewControllers count] > 1) {
[source performSegueWithIdentifier:@"showDetail" sender:source];
if (appDelegate.masterPopoverController) {
[appDelegate.masterPopoverController dismissPopoverAnimated:YES];
}
} else {
[source performSegueWithIdentifier:@"showDetailSmallDevice" sender:source];
}
}
[splitViewController.viewControllers count] is here just to separate large devices (iPads & iPhone 6 Plus) and the other, smaller ones
In your Storyboard, wire up one segue named showDetail which is actually a showDetail, to the detail navigation controller, and directly to the contents view controller another showDetailSmallDevice which is actually Show
(Push)

For an example, if you use:
self.imagePickerController = [[UIImagePickerController alloc] init];
self.imagePickerController.delegate = self;
self.imagePickerController.allowsEditing = YES;
the resulting image you get in - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info from info[UIImagePickerControllerOriginalImage] will have it's size less than the actual original, like it's happening to you.
But if you set self.imagePickerController.allowsEditing = NO;, UIImage from info[UIImagePickerControllerOriginalImage] will be the exact same size as it's in the library.

Recursive function calls passing by reference can overflow stack usage. If you initialize the entire stack/heap with a set value, you can then scan them to see how much has been used during a test (e.g. fill with 0x3F, post test look for how much of this is 'corrupted'). Set up test cases that maximize the usage to gain confidence that it won't overflow.
1) If memory is plentiful, expand the size of your stack/heap.
2) If memory is tight, consider only static allocation, and don't use library functions that malloc. Reduce function depth and avoid recursion. Consider pushing larger local function variables to globals.

Without modifying the API, you could use f_lseek(). Write open a file, use f_lseek() to expand the size of the file until 'disk full'(end of contiguous space). This would need to be repeated with new files until all of the disk was allocated. Pick from this the maximum allocated file, and delete the others.

Below is an example of how this affects JavaScript-based animations, and why it's important to me.
Pasted from my support.mozilla.org question
Go to pilatch.com/cards and click any of the cards in the arc. Now do the same in Chrome, or Safari, or IE 9. I have un-min-catted all my JavaScript, so you can see what's going on more easily.
CSS3 transforms in version 16 of FireFox are being converted into matrix transforms. It pretty much horks my rotate and scale animations. For instance, if you set the style attribute of an element to something like, style="transform:scale(0.75)", FireFox immediately converts that element's transform property, such as .style.transform to "matrix(...)".
I know how to do the linear algebra to convert rotate and scale via jQuery cssHooks into matrix transformations, and I've even written code to detect this "feature" of a browser, (that it forces a transform into matrix), and return a different hook that writes a matrix transform instead of a rotate transform, or scale, all in the past two days, on my development site.
However, it's proving to be increasingly challenging to make this new feature compatible with jQuery's animations. Going further, I may have to hack jQuery just to make this work for FireFox, or drop FireFox animation support altogether unless some FireFox developers make their new implementation backwards compatible.
I know that transforms normally get converted into matrices behind the scenes in the rendering engine. Leave your matrix there. Don't overwrite what the user has put in for a transform!
I also know that I should be using CSS3 animations, but, dangit, I started this project before those had widespread support. I can't rewrite all my animations because I want to support FireFox. That's not really an option. I'll direct my users to Chrome instead. I have more features in development that use these types of animation, and I'm in too deep to turn back.

ERROR: While executing gem ... (Errno<IP_ADDRESS>EPERM)
Operation not permitted - connect(2) for "<IP_ADDRESS>" port 53
I'm on a Mac which reports macOS Sierra 10.12.6.
I have Xcode Version 9.2 (9C40b).
I have rvm installed, and I'm using ruby 2.2.9. I get the same behavior with ruby 2.5.0. Same deal if I try to sudo gem install json-schema. Same thing if I try sudo gem install json-schema -n /usr/local/bin
If you're wondering why I haven't upgraded to High Sierra yet, it's because my coworkers have, and let's just say it has not gone well for them. :/

The application's main purpose is to collect some data and send it via GPRS (using the FTPClient of the Apache commons library)
The application was running fine, and then lately I added the ability to compress a file before sending it. Following is the code that compresses the file:
public static boolean compressFile(String file, String fileCompressed)
{
boolean result = false;
try
{
Process process = Runtime.getRuntime().exec("tar -czvf " + fileCompressed + " " + file);
System.err.println("Compression in progress");
int returnValue = process.waitFor();
System.err.println("Finished compression");
BufferedReader stderror = new BufferedReader(new InputStreamReader(process.getErrorStream()));
String s;
s = stderror.readLine();
if (s == null)
{
result = true;
} else
{
result = false;
System.err.println(s);
}
} catch (IOException e)
{
result = false;
Log.getInstance().newMessage(e.getMessage(), Log.ERROR);
} catch (InterruptedException e)
{
result = false;
Log.getInstance().newMessage(e.getMessage(), Log.ERROR);
}
return result;
}
After adding this function, the application started crashing! The log didn't contain any memory error or exception and the system it's running on lacks correct configuration, so the syslog doesn't show anything as well (the equipment maker told me that it will be available in the upcoming version). I can't even launch the VM in debug mode!
I have to add that the application doesn't crash during the compression, it just crashes randomly during its execution. The thing is that it crashes only when compression is enabled!
Has anybody seen this before? does anybody have an idea on how to debug/solve this?

The odd part is that first time I call my code when impersonating a local user on my PC which also is created as a local user on the server, I get a 2059. The second time I call the exact same code literally 2 seconds after, I can now read messages from the queue. Really odd, but calling the read method twice did the trick.

So when someone for instance enters http://www.example.com/Something, they are automatically redirected to something like http://www.example.com/Templates/12ES.html?ID=a_very_long_string&URI=Something.
This is all done in one PHP file, and the ID and URI parameters are dynamic.
Is there a way to keep the URL the user entered in the browser while I let PHP do the redirecting silently?
Thanks.

Find the equation of the plane that is tangent to the plane x = y² + z² - 2 on the point P(-1,1,0).
I got the equation x = 2y - 3 out of $F_{x}\Delta x + F_{y}\Delta y + F_{z}\Delta z = 0 $.
However this is a line, not a plane.
Are my calculations just plain wrong? Or if I did the math right, then what does this mean? Why do I get a line instead of a plane?

Clicking on the button will direct the panel to state "State2" adding another two buttons into the panel. During the state change, I want the panel to resize first and then show the newly added two buttons, so I applied transitions onto the state change.
My question is:
If I put the two buttons within a HBox directly under the addChild tag, it works fine. However, if I create a new component with the same code (HBox with two buttons in it) and then add the new component to the panel (Comp in the code commented), it won't show the resize effect.
Could someone tell me how to fix this? Thanks in advance.

That means track when a point changes it's position and react to it. This is much more efficient as it needs less processing and refreshes the positions faster than every 1 second. You should probably put in some function-call-per-time cap if your points float around because then these events would be called very often.

During feasibility stage , I've been linking libs on my project using nuget, storing the project in Git, so far so good.
Before going in production stage, I would like to be able (at least for each production release, even for nightly builds if possible) to have "somewhere" the source of all the libraries that I use.
There might be a strategy for doing this without nuget but with git and submodules, but It doesn't look obvious for me.
Anyone has an idea about how to do this ?
Thanks !

My problem is : I would like that all my views "objects" share a couple of dependency properties (view title, help context , etc ...).
The problem is : you cannot put the same DP name to several objects, you can not

You can look at the vertices and all that and can even edit it. But some are just symbols which are not readable. My question is: Is there a way to be able to read the information?
What I am trying to do is change the texture path name. The name that the .x file tells directx to go to to load a texture from file. What happens is I downloaded an .x file and the textures are not being loaded because the pathname for the textures is the pathname that whoever created the file used. And obviously I need to change it to where I have the textures now. Or I would have to create folders that match the pathname of every .x file I use which would just be silly.
Anyway, any help would be greatly appreciated.

Mic choice boils down to how a mic sounds to you in the situation you place it. So your choice for your second mic would work fine since there's really no "wrong" answer. That being said, I'm not sure you wouldn't be better served upgrading your LD mic since getting a mic that offers different polar pattern choices expands what/how you can experiment.

This has to be done with PET or other diagnostics to arrive at the correct conclusion.
However, as far as 'sacred' or metaphysical......the shape of the cochlea in the ear (natural biologic resonation chamber) and the mathematical science behind the theory of A-432 seems highly plausible https://www.youtube.com/watch?v=mdJinKf-lnw
The human experience detects and reacts to the subtle events...such as 8 cycles per second....IMO.....especially in prolonged exposure..such as normal modern audiophilic activities.
The experiment with the metal and the sand showing the perfectly formed patterns with A-432 I feel is conclusive to prove a dissonance exists in the tactile and biological architectural realm. Plus the body is 70% 'water' which has been shown to give the same pattern generated results.
As a Professional musician there is NO DOUBT that music effects activity and the 'pace' of human activity.....MUZAK proved that with elevators.....internal thought and healing are natural not psychic human activities so my conclusion is 'YES' A-432 is probably a better vibrational experience which most likely has deeper results in the physical body.

I hope this code will help you:

How to do that is very well explaned here configuring SpringBoot for MSSQL :
From the Start menu, open SQL Server 2014 Configuration Manager.
Click Protocol for SQLEXPRESS under SQL Server Network Configuration on the left pane.
On the right pane, right- click TCP/IP, and select Properties.
On the TCP/IP Properties dialog box that appears, click the IP Addresses tab. Scroll down to locate the IPALL node.
Remove any value, if present for TCP Dynamic Ports and specify 1433 for TCP

Now click OK and restart your SQL Server.

I'd like to incorporate the ability for a user to log in using Facebook or Twitter instead of having to type in their username and passwords. Part of the feature is the site owner would be able to turn this feature on and off, depending on their security preferences for managing their site.
I've got the app set up in Facebook and Twitter, though what I'm running into is that the request will only ever be bounced back to one URL, even though I'm intending that the CMS be downloaded and installed on separate domains and run independently from one another.
I've tried setting up a simple service that my CMS can dial home to (which is where the responses have to be funneled to due to Facebook and Twitter policy). Idealistically, my service would retrieve the user's facebook or twitter ID, and output the response data as an XML feed so that my CMS could parse the response and log them in accordingly. The part that I'm snagged on is the feed will prompt the user to login every time, so it seems like the permissions are not where they need to be, or the data just isn't crossing the domains appropriately.
What am I missing here?

I'll also describe the code here so just in case anything happens with the fiddle, it's here in perpetuity.
The Fiddle
https://jsfiddle.net/GrafikMatthew/7nx53twL/
The Libraries
I'm using the 2.2 jQuery library for this, though I'm pretty sure an earlier version could be used if needed.
<script src="https://code.jquery.com/jquery-2.2.0.min.js"></script>
The CSS
This is just a barebones presentation so these are the minimum styles required for this approach. You can modify these all you want to match your page design.
<style type="text/css">
.nav-wrapper ul
{
margin: 0;
padding: 0;
list-style-type: none;
}
.nav-wrapper > ul<IP_ADDRESS>after
{
content: "";
clear: both;
display: block;
float: none;
height: 0;
}
.nav-wrapper > ul > li
{
display: block;
float: left;
padding: 10px;
position: relative;
}
.subnav-wrapper
{
display: none;
background: #000;
position: absolute;
top: 100%;
left: 0;
}
.subnav-wrapper > ul > li {
padding: 10px;
}
.subnav-wrapper > ul > li > a
{
white-space: nowrap;
color: #fff;
}
.nav-wrapper > ul > li:hover
, .nav-wrapper > ul > li.hover
{
background: #000;
}
.nav-wrapper > ul > li:hover > a
, .nav-wrapper > ul > li.hover > a
{
color: #fff;
}
.nav-wrapper > ul > li:hover > .subnav-wrapper
, .nav-wrapper > ul > li.hover > .subnav-wrapper
{
display: block;
}
</style>
The HTML
I'm using a fairly straight forward markup for this menu structure, though since everything aside from the list and anchors, targeting is done via class name, so the elements can be swapped out for ones that work better for your project.
<div class="nav-wrapper">
<ul class="nav">
<li><a href="#link-a">Link A</a>
<div class="subnav-wrapper">
<ul class="subnav">
<li><a href="#link-a-a">Sublink A A</a></li>
<li><a href="#link-a-b">Sublink A B</a></li>
<li><a href="#link-a-c">Sublink A C</a></li>
</ul>
</div>
</li>
<li><a href="#link-b">Link B</a></li>
<li><a href="#link-c">Link C</a>
<div class="subnav-wrapper">
<ul class="subnav">
<li><a href="#link-c-a">Sublink C A</a></li>
<li><a href="#link-c-b">Sublink C B</a></li>
<li><a href="#link-c-c">Sublink C C</a></li>
</ul>
</div>
</li>
<li><a href="#link-d">Link D</a></li>
</ul>
</div>
<hr />
<div class="dummy">
<p>Dummy content...</p>
</div>
The JS
I'm using a standard anonymous enclosure and exposing jQuery via $.
<script type="text/javascript">
(function($){
function MH_ResetAll() {
$( '.nav-wrapper .hover' ).removeClass( 'hover' );
}
function MH_Init() {

<tr class="text-center" ng-repeat="ticket in filteredTickets = (vm.tickets | orderBy : vm.propertyName : vm.reverse | filter : vm.search | limitTo:vm.itemsPerPage:vm.itemsPerPage*(vm.currentPage-1))">
And a search input
<input class="form-control w25 pull-right" ng-change="vm.searchChanged()" type="text" ng-model="vm.search" placeholder="Search..." />
And I created a fake td to get the value of filteredTickets.length (because I cannot get the value of this in the scope, if you know a way tell me)
<td class="hidden" id="filteredTicketLength">{{filteredTickets.length}}</td>
basically the innerText of this will have the length of the tickets after the filtering.
Now here comes the problem. When I type something on the input search the totalItems does not update until I write/delete another character. Basically, the correct message is displayed after I write/delete another letter
<span class="pull-left">Showing {{filteredTickets.length}} tickets of {{vm.totalItems}} found.</span>
vm.searchChanged = function () {
var filteredTickets = document.getElementById('filteredTicketLength');
console.log(filteredTickets);
if(filteredTickets !== null)
vm.filteredTicketLength = filteredTickets.innerText;
vm.totalItems = vm.filteredTicketLength;
};
How can I write that message showing x items of x found after the filtering? It's like the searchChanged function is being run before the filteredTicketLength is updated.

I put it in an "Execute SQL Task" in the Control Flow, set the resultset to XML.
Now how to I get the results into an actual xml file that I can turn around and FTP to a third party?
This should have been so easy! I would put the XML into a variable but we are looking at a HUGE file, possibly 100mb+
Do I need to use a Script Task? (I'd like to avoid that if there is another option.)

(DT_I8)(ISNULL((DT_STR,5,1252)Column_Name) ? (DT_I8)NULL(DT_I8) : (DT_I8)(DT_STR,5,1252)Column_Name)
I did this in a derived column with both your way and my way coming from a DT_STR field that stored numbers and managed to get an eight-byte signed integer.
Hope this helps!

After explicitly stating the API path to be /API/index.php and not just /API, it started returning the valid JSON!

The images are stored on the server and the source (path) is on a mySQL database. I want to be able to move to the next (or previous picture) by invoking two php functions I have made to do so. The code I have written so far is:
<?php
require "db_connection.php";
$query="SELECT source FROM photos";
$result=mysql_query($query);
$count=0;
$numberofpics=mysql_num_rows($result);
$image=mysql_result($result, $count, "source");

}
function slideshowBack() {
$num=$num-1;
if ($num==0) {
$num=$numberofpics;
}
$count=$count-1;
$image=mysql_result($result, $count, "source");
}
?>
The html portion to display the images is:
<!-- FORWARD AND BACK FUNCTIONS-->
<a class="back" href="http://mywebsite.com/discoverandrank.php?function=slideshowBack()"> <img src="graphics/back.png"/></a>
<a class="next" href="http://mywebsite.com/discoverandrank.php? function=slideshowForward()"><img src="graphics/forward.png"/></a>
<!--DISPLAY MIDDLE PHOTO-->
<div id="thepics">
<img src="http://www.mywebsite.com/<?php echo $image; ?>" name="mypic" border=0 height="300" width="500"></img>
</div>
I'm pretty sure that the php script is incrementing/decrementing the count currently for the image, but I think the problem might be because the html (specifically img src="....") part is not re-evaluated when the count of the image increases?

But when I goto frontend of the site, the user is not logged out. So my question is "Is separate session maintained for frontend and backend for same user?" If it so then why I didn't find the 2 session rows in session table of DB? Is frontend session stored in separate table?

the issue i'm facing is that the c++ code is not able to open the mp4 file when using the avformat_open_input function:
int PTSExtraction<IP_ADDRESS>parse_file(Platform<IP_ADDRESS>String^ filename)
{
int ret = 0;
AVPacket pkt = { 0 };
std<IP_ADDRESS>wstring fileNameW(filename->Begin());

if (avformat_open_input(&fmt_ctx, src_filename, NULL, NULL) < 0) {
fprintf(stderr, "Could not open source file %s\n", src_filename);
return 1;
}
// rest of code
}
the error received by avformat_open_input is Permission Denied. I cannot even open a random text file in this function by doing:
ofstream output;
output.open("output.txt");
I realize there are file system permissions that are blocking the C++ component of my uwp app from opening files. here are the things i have tried so far:
i have enabled broadFileSystemAccess in the Package.appxmanifest (https://blogs.windows.com/windowsdeveloper/2018/05/18/console-uwp-applications-and-file-system-access/) - in the Capabilities section of the Package.appxmanifest file I've allowed access to Location, Pictures Library, and Videos Library.
I've checked the File System Privacy Settings on my computer and enabled my app to access the File System.
I've tried moving the mp4 file to various locations (Documents, Pictures Library, Videos Library) to see if the C++ component has access to these locations.

# your original data frame
dat <- structure(list(ID = c(1L, 1L, 1L, 1L, 2L, 2L, 2L, 2L, 2L, 3L, 3L, 3L, 3L),
DATE = structure(c(3L, 4L, 5L, 5L, 2L, 3L, 4L, 4L, 4L, 1L, 2L, 3L, 3L),
.Label = c("9/18/2014", "9/19/2014", "9/20/2014", "9/21/2014", "9/22/2014"),
class = "factor")),
.Names = c("ID", "DATE"), class = "data.frame", row.names = c(NA, -13L))
# glue the columns to avoid need of grouping by ID first
dat2 <- paste(dat$ID, dat$DATE, sep='/')
# alternatively, you can use following for string comparison, if needed.
# dat2<-paste(as.character(dat$ID),as.character(dat$DATE),sep='/')
# create a lookup table for counts of each ID+DATE combo
lookup<-table(dat2)
# add a column based on counts. If count is 1 then ID+DATE is not duplicated.
dat$FL <- sapply(dat2,FUN = function(x) { if (lookup[x] == 1) 0 else 1})
# output
print(dat)
This should give you what you're looking for.
ID DATE FL
1 1 9/20/2014 0
2 1 9/21/2014 0
3 1 9/22/2014 1

There are more sophisticated ways to do this, and table() has its limitations, but for most part, this is simple, easy to read, and should do the job for you.

So, I thought of a (probably) simple problem that I couldn't figure out how to code in parallel Julia paradigm.
Let's say I have a matrix/dataframe df from some experiment. Its N rows are variables, and M columns are samples. I have a method pwCorr(..) that calculates pairwise correlation of rows. If I wanted an NxN matrix of all the pairwise correlations, I'd probably run a for-loop that'd iterate for N*N/2 (upper or lower triangle of the matrix) and fill in the values; however, this seems like a perfect thing to parallelize since each of the pwCorr() calls are independent of others. (Am I correct in thinking this way about what can be parallelized, and what cannot?)
To do this, I feel like I'd have to create a DArray that gets filled by a @parallel for loop. And if so, I'm not sure how this can be achieved in Julia. If that's not the right approach, I guess I don't even know where to begin.

Given a Lie group $G$ with Lie algebra $\mathfrak{g}$, if $\psi: \mathfrak{g} \rightarrow \mathfrak{X}(\mathfrak{g})$ is the infinitesimal action determined by the adjoint action then
$$ \psi \left( \left[ X , Y \right] \right) = - \left[ \psi(X) , \psi(Y) \right]\,. $$
Initially I assumed that the adjoint action was the usual $\mathrm{Ad}: G \rightarrow \mathrm{Aut}(\mathfrak{g})$ which would imply that $\psi = \mathrm{ad}$, however in this case, since we have that $\mathrm{ad}(X) (Y) = \left[X,Y \right]$ and then through the Jacobi identity one obtains
$$ \mathrm{ad} \left( \left[ X,Y \right] \right) (Z) = \left[ \mathrm{ad}(X) ,\mathrm{ad}(Y) \right] (Z) $$
which does not agree with what is asked. I guess I'm probably looking at the wrong thing but I can't understand what could also be meant by the adjoint action in that case.
Any pointers on what is $\psi$ (if indeed it is something different than what I interpreted it to be) or otherwise on what I might be doing wrong, would be greatly appreciated.

These spin-groups can be constructed using Clifford algebras and they are therefore useful in constructing spinor (projective) representations of $SO(p,q)$. As an simple example take $G=SO(3)=SU(2)/\mathbb Z_2$, it has only integer spin representations. To find the projective representations we can use $\tilde G = \text{spin}(3) = SU(2)$. This has integer spin representations AND half-integer spin (spinor) representations. |

First, create an instance template, specifying the VM configuration that you need:
gcloud compute instance-templates create TEMPLATE_NAME \
--machine-type MACHINE_TYPE \
--image-project IMAGE_PROJECT \ # project where your boot disk image is stored
--image IMAGE \ # boot disk image name
--boot-disk-type pd-ssd \
--boot-disk-size 50GB \
--boot-disk-auto-delete \
--boot-disk-device-name DEVICE_NAME \ # boot disk device name, the same for all VMs
--subnet default \
--maintenance-policy MIGRATE \
[...]
Note:
You specify boot disk as part of instance template.
No need to specify zone for instance template. You will specify desired zone at instance group creation time.
Device name is the same for boot disks of all VMs in the group. This is not a conflict because device name of a particular disk is seen from guest OS of each specific VM and is local to that VM.
Other parameters are the same as those for creating a VM.
Then, create a group of 4 (or 100, or 1000+) VMs, based on this template:
gcloud compute instance-groups managed create GROUP_NAME \
--zone ZONE \
--template TEMPLATE_NAME \ # name of the instance template that you have just created
--size 4 \ number of VMs that you need to create
The group creates multiple similar VMs, based on your template, much faster than you would do it by iterating creation of standalone VMs.

gameObject.enemyCountt.enemiessCount --;
if these arent in the same gameobject, then you can make a reference from the other gameobject with the other script
public GameObject OtherObject;
void Update(){
if (collision.gameObject.tag == "Enemy") {
OtherObject.enemyCountt.enemiessCount --;
}
then you have in the object, where you added the script, a free field, where you can drag & drop your GameObject with the script "enemyCountt" and then it should work, but I'm not quite sure

With JSON.NET all you need is adding JsonProperty attribute and specify its custom name that appears in resulting JSON. Here is the example:
public class MyClass
{
[JsonProperty(PropertyName = "24hhigh")]
public string Highest { get; set; }
...
Now to deserialize:
string jsonData = ...
MyClass deserializedMyClass = JsonConvert.DeserializeObject<MyClass>(jsonData);

If you inspect the json schema, you will not find any max restriction defined: deployment template schema. However, Azure deployment template is limited in total size and must no exceed 1MB:
You must limit the size your template to 1 MB, and each parameter file to 64 KB. The 1 MB limit applies to the final state of the template after it has been expanded with iterative resource definitions, and values for variables and parameters.
Do not be confused with resources element though, which is constrained to the 5 levels of nesting:
The resources property allows you to specify child resources that are related to the resource being defined. Child resources can only be defined 5 levels deep. It is important to note that an implicit dependency is not created between a child resource and the parent resource. If you need the child resource to be deployed after the parent resource, you must explicitly state that dependency with the dependsOn property.
Finally, I can't imagine any situation where you would have more than 10 nested templates. Just think about maintainability and how challenging would it be to debug/troubleshoot failing deployment

I'm already stuck using regex, and it already works as I need to, except one special case, which is what I need advice on.
I need to scan through some JavaScript-like code and insert the new keyword in front of every object declaration. I already know the names of all objects that will need this keyword, and I know that none of them will have that keyword in the code before I start (so I don't need to deal with repeated new words or guessing whether something is an object or not. For example, a typical line could look like this:
foo = Bar()
Where I would already know that Bar is a 'class' and would need 'new' for object declaration. The following regex does the trick:
for classname in allowed_classes:
line = re.sub(r'^([^\'"]*(?:([\'"])[^\'"]*\2)*[^\'"]*)\b(%s\s*\()' % classname, r'\1new \3', line)
It works like a charm, even making sure not to touch classname when it's inside a string (The first portion of the regex tells it to make sure there are even number of quotes before-hand - it's a bit naive in that it will break with nested quotes, but I don't need to handle that case). Problem is, class names could also have $ in them. So the following line is allowed as well if $Bar exists in allowed_classes:
foo = $Bar()
The above regex will ignore it, due to the dollar sign. I figured escaping it would do the trick, but this logic seems to have no effect on the above line even if $Bar is one of the classes:
for classname in allowed_classes:
line = re.sub(r'^([^\'"]*(?:([\'"])[^\'"]*\2)*[^\'"]*)\b(%s\s*\()' % re.escape(classname), r'\1new \3', line)
I also tried escaping it by hand using \ but it has no effect either. Can someone explain why converting $ to \$ isn't working and what could fix it?
Thanks

I am trying to take the json from a url and just render it visually in the browser. It doesn't even need to be formatted, at least it doesn't until I get past this hurdle.
I can get it to show up in the console via console.log, but I can't seem to get the response into the render method. I've simplified it down to the code below until I can see something on the page.
import React, { Component } from 'react';
// import axios from 'axios';
var co = require('co');
co(function *() {
var res = yield fetch('https://api.stackexchange.com/2.2/search?order=desc&sort=activity&intitle=perl&site=stackoverflow');
var json = yield res.json();
console.log(res);
});
class App extends Component {
render() {
return (
<div className="App">
INSERT JSON HERE
</div>
);
}
}
export default App;
I have also retrieved the response using
fetch('https://api.stackexchange.com/2.2/search?order=desc&sort=activity&intitle=perl&site=stackoverflow')
.then(function(res) {
return res.json();
}).then(function(json) {
console.log(json);
});
I originally started by using axios because I thought "oh man, I'm going to use axios because who's awesome? I'm awesome."
axios.get('https://api.stackexchange.com/2.2/search?order=desc&sort=activity&intitle=perl&site=stackoverflow')
.then(function(response) {
console.log(response.data);
});
but that was a fallacious because today I am not awesome.
I'll take whatever help I can get! My original plans also included using map to just iterate over the "items" so extra points if you can steer me closer to salvation in that area.

export class MyPage {
balance: number;
getBalance(outerThis: MyPage){
this.restProvider.getBalance(this.user_id)
.then(data => {
this.todos = data;
outerThis.balance = this.todos.balance;
this.timersecs = this.todos.timer;
/// HERE ///
});
}
then depending on where you are calling getBalance() from, you would pass a reference to your page as a parameter. E.g. if calling from somewhere within the page itself, you would say:
this.getBalance(this);

I've defined the following rule to add the last two numbers in the stream together. I then send in a stream of 100 events, with the values set from 1 to 100. So I would expect the output to be 0, 1, 3, 5, 7, 9, 11, 13 etc.
declare TestEvent
@role( event )
value : int
end
rule "Simple Rule"
when
$sum : Integer() from accumulate ( TestEvent( $value : value ) over window:length( 2 ); sum( $value) )
then
System.out.println("Value: " + $sum );
end
The session is started using "fireUntilHalt" in a separate thread. If I put a delay of 10 milliseconds between every event inserted it works as expected. However when I don't have the delay, the results aren't as expected. Usually it just prints 0 and 197. Sometimes I might get a number or two in-between as well.
Why does this happen and what I should do to fix?

and then call the string version of the constructor of that class to create a new instance of the object. This will only work if the classes you are using have a String constructor (which Long and String does - but Character doesn't).
Do you need to store the Attribute value as a varchar in the DB? Could you not store the serialised Java object? Then you can just de-serialise it straight from the DB and you have the correct object already created.

that the second will throw exceptions if it cannot be sent, which is
why I tend to prefer using it. Something to keep in mind though, is
that using deliver! will call any registered Mail Observers, but not
Interceptors - meaning that your mail will be sent unaltered.

Depending on the underlying datastore, by the time it merges the entity, the same entity record from the repository may already be altered with different information so any of that altered information may be lost and overwritten by the later merge.
Instead of using EntityManager.merge(T entity), use EntityManager.createQuery(CriteriaUpdate updateQuery).executeUpdate(). This should only update the values of the specified attributes you provide.
@Transactional
public void methodA(Long id, String color) {
final CriteriaBuilder cb = entityManager.getCriteriaBuilder();
final CriteriaUpdate<Fruit> updateColor = cb.createCriteriaUpdate(Fruit.class);
final Root<Fruit> updateRoot = updateColor.from(Fruit.class);
updateColor.where(cb.equal(updateRoot.get(Fruit_.id), id));
updateColor.set(updateRoot.get(Fruit_.id), id);
entityManager.createQuery(updateColor).executeUpdate();
}
@Transactional
public void methodB(Long id, int price) {
final CriteriaBuilder cb = entityManager.getCriteriaBuilder();
final CriteriaUpdate<Fruit> updatePrice = cb.createCriteriaUpdate(Fruit.class);

updatePrice.where(cb.equal(updateRoot.get(Fruit_.id), id));
updatePrice.set(updateRoot.get(Fruit_.price), price);
entityManager.createQuery(updatePrice).executeUpdate();
}
As long as no other transaction updates the same fields as either of these methods, then there should no longer be any issues with this update.

In such a scenario would it help to use either an elastic lanyard or a "energy absorber"? My guess is that 1) the fall is somewhat slowed down, and 2) the expansion of the elastic sling/absorber both makes it easier for the others to notice as well as gives them more time to react. But I have not seen this in practice, hence the question.

In order to act on behalf of an account, you need its private key. As such, if the node is down it is impossible to retrieve any accounts associated with it through other nodes.
That would defeat the purpose of having a blockchain as a blockchain network consists of peers whose owners you do not necessarily trust, let alone entrust with the private key(s) to your account(s).

const data = require('./data.json');
Now the JSON data is stored inside the variable data. To access the members, use the dot operator. data.room will return the array of rooms.
To access the individual room, use data.room[i] where i is the numbered element in the array (starting from 0). For example, to access the first room:
const first_room = data.room[0];
This first_room variable can now be used to access the name.
console.log(first_room.name);
This will log "room1" to the console.

// Code that needs fixes!
async function jwtAccessAuthCheck(accessToken) {
// This part is fine. We are in the main async flow.
if (!accessToken) {
return Promise.reject('Empty access token');
}
// This needs to be rewritten, as the async function itself doesn't know anything about
// the outcome of `jwt.verify`...
jwt.verify(accessToken,"dipa",function(err){
if(err) {
// This is wrapped in a `function(err)` callback, so the return value is irrelevant
// to the async function itself
return Promise.reject('TokenExpiredError.');
} else {
// Same problem here.
return Promise.resolve();
}
});
// Since the main async scope didn't handle anything related to `jwt.verify`, the content
// below will print even before `jwt.verify()` completes! And the async call will be
// considered complete right away.
console.log('Completed before jwt.verify() outcome');
}
A better rewrite would be:
// Fixed code. The outcome of `jwt.verify` is explicitly delegated back to a new Promise's
// `resolve` and `reject` handlers, Promise which we await for.
async function jwtAccessAuthCheck(accessToken) {
await new Promise((resolve, reject) => {
if (!accessToken) {
reject('Empty access token');
return;
}
jwt.verify(accessToken,"dipa",function(err){
if(err) {
reject('TokenExpiredError.');
} else {
resolve();
}
});
});
// We won't consider this async call done until the Promise above completes.
console.log('Completed');
}
An alternate signature that would also work in this specific use case:
// Also works this way without the `async` type:
function jwtAccessAuthCheck(accessToken) {
return new Promise((resolve, reject) => {
...
});
}
Regarding your cancelDansok(req, res) middleware, since jwtAccessAuthCheck is guaranteed to return a Promise (you made it an async function), you'll also need to handle its returned Promise directly. No try / catch can handle the outcome of this asynchronous task.
exports.cancelDansok = function (req, res) {
...
jwtAccessAuthCheck(accessToken)
.then(() => {
log.info("jwt success");
return doCancel(dansokSeqNo);
})
.then(() => {
log.info("cancelDansok() finish");
res.status(200).json({ message: 'cancelDansok success.' });
})
.catch(e => {
res.status(e.status).json(e);
});
};
I strongly suggest reading a few Promise-related articles to get the hang of it. They're very handy and powerful, but also bring a little pain when mixed with other JS patterns (async callbacks, try / catch...).

/server/rest-api/v1/index.js

On a side note, if you are dealing with many routes this way, it may be handier for you to define your API entry point once ('/api/v1'), when mounting the router. This way your "business" routers don't need to know the entry path themselves (and it should not matter to them), which is convenient if you ever need to change that path one day.
Then again this is up to you and how you want to design your server :)
Example :
server.js
app.use('/api/v1', require('./server/rest-api/v1'));
/server/rest-api/v1/index.js
var express = require('express'),
router = express.Router(),
product_router = require('./products');
router.use('/purchases/products', product_router);
module.exports = router;
/server/rest-api/v1/products/index.js
var express = require('express'),
router = express.Router(),
create_product = require('./create-product.controller');
router.route('/new').post(create_product.post);

Talking about chroot, it can be always used in a way that is insecure, but SSH is trying to avoid the insecure use cases the most. In the first place, it will not allow to use chroot on directory, that is writable by anyone else but root. Using internal-sftp significantly limits what the user can do inside so unless there is very serious security vulnerability, you should be fine with that.

I also need it to run in its own Fragment and be able to handle orientation changes and the activities onPause() or onStop() without losing any time.
Would it be better to use Intent Service and a Results Reciever? if so how would i accomplish this?

Now I want to add some more information from the user profile to the search results of the people search. So far I've successfully changed the display template for the people item to include the WorkPhone for example.
Now I want to include the Office (room) into the result. When looking at the properties of an AD user, this is the field General tab -> Office.
The AD import to SharePoint apparently works, because the user profile contains the value I entered in the AD. Here this is in the property "Office" (User Profile Service Application -> Manage User Properties).
But now I'm not sure how this property can be mapped to the SP2013 search (to a managed property which I can then include in the display template).
In the Search Service Application -> Search Schema, there is no crawled property "Office", and also no managed property of that name. There is a crawled Property "People:Office" which is mapped to the managed properties "OfficeNumber" and "ContentsHidden". I included both in the display template, but the template seems to find no values for them (I'm logging the values found in ctx.CurrentItem to the javascript console, but there are no values for either property, in fact, neither appear as properties on the ctx.CurrentItem object).
There is also a managed property "BaseOfficeLocation" which maps to the crawled property "People:SPS-Location" but this is not the one I want.
So, my question is: Does anyone know how the property "Office" in the user profile service application is mapped to the search managed properties?

Now I understand that those (User Profile) properties are preceded with "People:". But: when I add the corresponding properties to my display template (under mso:ManagedPropertyMapping), like "OfficeNumber":"OfficeNumber", then I still do not get a value for it. I'm logging all values I find in the ctx.CurrentItem to the console, and it does not have an OfficeNumber value. I did a full crawl inbetween, and made sure the profile has a value in the field. But it is not found in the display template. |

the class you create needs to implement
public void OnAuthorization(AuthorizationContext filterContext)
and then you can use
string controllerName = filterContext.RouteData.Values["controller"].ToString();
and the same, substituting "action" for "controller" (make sure you check for nulls in these values first). In MVC 2 this can be changed to filterContext.ActionDescriptor.ActionName and .ActionDescriptor.ControllerDescriptor.ControllerName and you won't have to check for nulls

I can suggest you the same ADC MCP series with I2C interface.Thus, the further I2C connections with MCP23017 expander and then the Raspberry pi would be easy.You can go through various analog to digital converters that can be I2C interfaced with their codes in python or java for pi like MCP3425, MCP3426, MCP3427, MCP3428. You can easily find them or also check control everything as that would be easy to interface using I2C cables and adapters preventing connection or wiring problems.For codes: https://github.com/ControlEverythingCommunity?utf8=%E2%9C%93&query=MCP34
The following codes for MCP_23017 can also help you code the way you want easily with expander being connected to pi:https://github.com/ControlEverythingCommunity/MCP23017_16-Channel.
I think this would solve your problem!!
Thanks.

I would like to make an array with the same size as the original data but with zeros when the data is masked and with ones where it is not masked. So fare I have tried to make this function:
def find_unmasked_values(data):
empty = np.ones((len(data),len(data[0]),len(data[0,0])))
for k in range(0,len(data[0,0]),1): # third coordinate

But this only returns an array with ones and no zeros eventhough there is masked values in the data. If you have suggestions on how to improve the code in efficiency I would also be very happy.
Thanks,

1) previous values from data1 or
2) with data from another (also masked dataset, data2) if the found value from data1 < the found value from data2.
So fare I have tried a couple of things, one is to make a very complex script with long for loops which never finished running after 24 hours. I have tried to reduce it, but i think it is still very much to complicated. I believe there is a much more simple procedure to do it than the way I am doing it now I just can't see how.
I have made a script where masked data is first replaced with zeroes in order to use the function np.where to get the index of my masked data (i did not find a function that returns the coordinates of masked data, so this is my work arround it). My problem is that my code is very long and i think time consuming for large datasets to run through. I believe there is a more simple way of doing it, but I haven't found another work arround it.
Here is what I have so fare: : (the first part is just to generate some matrices that are easy to work with):
if __name__ == '__main__':
import numpy as np
import numpy.ma as ma
from sortdata_helpers import decision_tree
# Generating some (easy) test data to try the algorithm on:
# data1
rand1 = np.random.randint(10, size=(10, 10, 10))
rand1 = ma.masked_where(rand1 > 5, rand1)
rand1 = ma.filled(rand1, fill_value=0)
rand1[0,:,:] = 1
#data2
rand2 = np.random.randint(10, size=(10, 10, 10))
rand2[0, :, :] = 1
coordinates1 = np.asarray(np.where(rand1 == 0)) # gives the locations of where in the data there are zeros
filled_data = decision_tree(rand1, rand2, coordinates1)
print(filled_data)
The functions that I defined to be called in the main script are these, in the same order as they are used:
def decision_tree(data1, data2, coordinates):
# This is the main function,
# where the decision between data1 or data2 is chosen.
import numpy as np
from sortdata_helpers import generate_vector
from sortdata_helpers import find_value
for i in range(coordinates.shape[1]):
coordinate = [coordinates[0, i], coordinates[1,i], coordinates[2,i]]
AET_vec = generate_vector(data1, coordinate) # makes vector to go back in time
AET_value = find_value(AET_vec) # Takes the vector and find closest day with data
PET_vec = generate_vector(data2, coordinate)
PET_value = find_value(PET_vec)
if PET_value > AET_value:
data1[coordinate[0], coordinate[1], coordinate[2]] = AET_value
else:
data1[coordinate[0], coordinate[1], coordinate[2]] = PET_value
return(data1)
def generate_vector(data, coordinate):
# This one generates the vector to go back in time.
vector = data[0:coordinate[0], coordinate[1], coordinate[2]]
return(vector)
def find_value(vector):
# Here the fist value in vector that is not zero is chosen as "value"
from itertools import dropwhile
value = list(dropwhile(lambda x: x == 0, reversed(vector)))[0]
return(value)
Hope someone has a good idea or suggestions on how to improve my code. I am still struggling with understanding indexing in python, and I think this can definately be done in a more smooth way than I have done here.
Thanks for any suggestions or comments,

@media (min-width: 600px) and (max-aspect-ratio: 21/15), (min-width: 768px) {

My only theory so far is it might be a bug with WebViews (this is currently in a web view).

My assumption is that I might be able to just add points anywhere on the line of the circle's path in something like Figma. If that's the case, it's 22 points I need, correct?

But Chrome will wait until the CSS files have finished downloading before downloading the local javascript files. It (chrome) does NOT wait when those javascript files are external though. I thought it might be a number-of-resources issue, but I am not downloading ANY files from the root domain other than the index.html document and those two local javascript files.
This is true if I don't include the external javascript files or not, or if the external files are included before the local files.
Both local and external included together as described in the HTML above :
Only Local files : Notice how the two images are requested, if I refresh the page, they will show up in a random order and the fact that they are included first here is happenstance... obviously they are all waiting for the same thing before requesting :
I'd prefer the local files to download concurrently with the CSS files (serving them from the same CDN as the CSS files results in the same behavior above... presumably because Chrome only downloads a few resources from the same domain at a time) so that I don't have to pay for the DNS lookup of the additional CDN so my question is "Why doesn't chrome download my locally referenced files at the same time it would download external files?"

I need to load a data from server and show it with DataTables and each cell is binded with knockout.
The table should have basic functions: Search, Sorting, Pagination.
each item must have a Column with some actions like: Edit, Remove, Link.
editing must be made in Modal Window

table.destroy();
}, null, 'arrayChange');
}
var nodes = Array.prototype.slice.call(element.childNodes, 0);
ko.utils.arrayForEach(nodes, function (node) {
if (node && node.nodeType !== 1) {
node.parentNode.removeChild(node);
}
});

For reference, "Line of Sight" (pg 12) from the Rules of Play:
In order for a figure to have line of sight to a space, a player must be able
to trace an uninterrupted, straight line from any corner of that figure’s
space to any corner of the target space.
If the line passes through the edge of a map tile, a door, or a blocked space
(a space containing a figure or obstacle), the target space is not in line of
sight (see “Line of Sight Example” on page 12).
If the line passes along the edge of a blocked space (see “Line of Sight
Example” on page 12), the target space is not in line of sight. However,
if the line only touches the corner of a blocked space (without passing
through the space itself ), the target space is in line of sight.
Now let's address the possible lines from the Hero's space:
Top left corner
Any line from this corner must pass through the Hero's space. The Hero is a figure, so the Hero's space is a blocked space. So all lines are invalid because they pass through a blocked space.
Bottom left corner
Bottom right corner
For both of these corners, any line must pass through or along the Obstacle space. An obstacle space is a blocked space, therefore all lines are invalid.
Top right corner
Only a single line can pass from this corner through the obstacles. By geometry, that fixed line does continue to the Monster's bottom right corner, but passes through the Monster's space. A monster is a figure, so therefore the Monster's space is a blocked space. Therefore, the line passes through the edge of a blocked space and is invalid.
Summary: All possible lines are invalid; the Monster can't be targeted by the Hero.

You will be able to generate your client code, tests and documentation using a set of tools supporting WADL. Some examples can be found here. Also, I think you should stick with WADL, rather than WSDL 2.0 because it is less verbose and way simpler (IMHO). In fact, in WADL you describe exactly what the user sees on the documentation page, just using WADL XML syntax. BTW, that is why it's so easy to write XSLT-based documentation generators for WADL.

I know the basic concepts of a thermometer, but let's say the car is sitting in the sun for the whole day. The outside parts of the car are heated up and the thermal energy eventually spreads to all parts of the car, which, even when hidden in "shadow" under the hood, also includes the thermometer at some point. Doesn't this mean the measurement of air temperature would be incorrect? Another scenario would be going 100mph, in which (at least the front of) the car is eventually cooled down by giving of thermal energy to the headwind, again distorting the measurement. I can imagine the thermometer could be isolated from those effect, but in case of perfect isolation, it would not measure anymore, and in case it's not a perfect isolation, the measured temperature would eventually be distorted at some point. Same goes with isolator/conductor combinations, as the conductors have to take the airs' temperature from somewhere and this location has to have "neutral" and unaltered temperature. However, the car's thermometer always shows pretty reliable values (e.g. 20°C), even when standing in the sun for hours or going really fast or even both.
Are the effects I'm describing too miniscule to be visible, is the shown temperature just an approximation or am I missing something completely different?
Depending on the answer, this may lead to a more abstract question:
Is there even something as a spatial air temperature or is it ultimately relative to the specific circumstances of the measuring device and thus, dependent on the very exact location of latter, making every temperature indication an approximation?

<PERSON> is playing archery blindfolded. The first arrow he shoots unfortunately misses the bull's-eye. The second arrow misses the bull's-eye even further. <PERSON> still shoots a third arrow. How big is the chance that his third shot is also worse than his first shot?
Now the given solution is: We have first two marks as [A B] (here, A is left to 'B' means A is closer to Bull's eye than B). So C has following $3$ possibilities to take on, viz.:
[A B C]
[A C B]
[C A B]
So, the probability that C is worse than A is $\frac 2 3$ i.e. the cases [A B C] and [A C B].
My doubt here is that this probability of $\frac 2 3$ would be true only when above three possibilities are equally likely. But they don't seem to be equally likely because if we look a bull's eye:
Now, farther we move from bull's eye, we have more area to hit on and so probability to perform worse than a shot should be more than the probability to perform better than it, for e.g. Suppose I first hit at the Red region, then to perform better than my first hit I need to hit in Yellow Region and to perform worse than my first hit I need to hit in Black or White or even out of the board and so probability of performing worse is more than that of performing better.
So, what is going wrong here? Or there is some other solution?

<PERSON> and <PERSON> play a match consisting of a series of games, where <PERSON> has
probability $p$ of winning each game (independently). They play with a “win by two”
rule: the first player to win two games more than his opponent wins the match. Find
the probability that <PERSON> wins the match (in terms of p) , in two different ways:
(a) by conditioning, using the law of total probability.
Why's my attempt below wrong? What to correct?
• Let P(C) be the probability that <PERSON> wins the match.
• Let W stands for Winning a game and L stands for losing a game.
So, possible ways of Games for winning the match = WW, WLW, LWW.
(i) WW $\implies$ <PERSON> wins first two games.
(ii) WLW $\implies$ wins first game, loses second game and wins third game.
(iii) LWW $\implies$ loses first game and wins next two games.
$\begin{align} \implies P(C) & = P(WW) + P(WLW) + P(LWW) \\
& = p*p + p*(1-p)*p + (1-p)*p*p \\
& = p^2(3-2p). \end{align} $
But this is wrong. The right answer is: $P(C) = \frac{p^2}{p^2+q^2}$.

In this query I want to remove "OFFSET @offsetFrom ROWS FETCH NEXT @offsetTo ROWS ONLY" if @isExportToExcel is true. the value of @isExportToExcel is being passed from java code. I tried with below CASE statement but it is not working
Case
when @isExportToExcel = 0 then 'OFFSET @offsetFrom ROWS FETCH NEXT @offsetTo ROWS ONLY' END
But this is not working and I am always getting completed data and pagination is not working with this

def determine_node_label_by_layertype(layer, layertype, rankdir):
"""Define node label based on layer type
"""
if rankdir in ('TB', 'BT'):
# If graph orientation is vertical, horizontal space is free and
# vertical space is not; separate words with spaces
separator = ' '
else:
# If graph orientation is horizontal, vertical space is free and
# horizontal space is not; separate words with newlines
separator = '\n'
Replace the separater = '\n' with separater = r"\n" and it seemed to work for me.

For example i have 1920x1080 screen size. And i have relative coords width (-100,100) and height = 200*1080/1920=112.5, height(-56.25, 56.25)
Can i use this relative coords to set width and height? and how to do it?
Is there any best practices to handle different screens ratio, handle orientation change correctly?
thanks in advance.
here is how i'm using it in my app:
create()
public void create() {
stage = new Stage();
Gdx.input.setInputProcessor(stage);
camera = new OrthographicCamera(Gdx.graphics.getWidth(), Gdx.graphics.getHeight());
camera.setToOrtho(true, Gdx.graphics.getWidth(), Gdx.graphics.getHeight());
camera.update();
Skin skinBackground = new Skin();
skinBackground.add("background", new Texture(Gdx.files.absolute(FilePathSlicer.preparePath(taskSheet.background.getPicUrl()))));
background=new Image(skinBackground,"background");
if(background!=null) {
background.setWidth(width);
background.setHeight(height);
stage.addActor(background);
}
}
render
public void render() {
Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
Gdx.gl.glClearColor(255/255f, 255/255f, 255/255f, 1);
stage.getBatch().setProjectionMatrix(camera.combined);
stage.act(Gdx.graphics.getDeltaTime());
stage.draw();
}

I am running VS2015 Community edition under VMWare Fusion 8.1 and Windows 10 (Windows Update reports all current patches are applied)
The emulator runs fine but the application fails to deploy/run with the same bootstrap error the original poster had.
Windows 10 (all configurations) work fine.

const { toptracks } = this.props;
then you can use it without referencing this.props.toptracks
Secondly the map function takes arguments of the element and the index but you have declared them as toptracks again which creates aliasing issues (at least in my mind) and is also just plain confusing...
return toptracks.map((toptracks,k) =>
should ideally be
return toptracks.map((toptrack,k) => - then remember to update the toptracks inside the map callback to toptrack to make it clearer which is the collection and which is the element
See https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/map for more info on the map function.
As already pointed out, if toptracks is not an array then you will need to turn it into an array or use .keys for example if it is an object.
