A: The first checkout will be a full checkout/copy.
All subsequent checkouts, will only pull changes since the previous checkout. For this to work, in your SCM portion of the job configuration, you need to make sure that Check-out Strategy is set to Use 'svn update' as much as possible

network-related or instance-specific error occurred while
establishing a connection to SQL Server. The server was not found or
was not accessible. Verify that the instance name is correct and that
SQL Server is configured to allow remote connections. (provider: TCP
Provider, error: 0 - A connection attempt failed because the connected
party did not properly respond after a period of time, or established
connection failed because connected host has failed to respond.)
i am sure of the ports as i checked the named instance configuration on the DB server, i also telnet the dynamic IP from the application server and it is going through. i also tried to connect a copy of the application from a demo server i have with the same configuration as the application server and it was successful. from the application server it is not, any suggestions?

I am attempting a fairly complex group of animations involving purely transitions and fixed backgrounds. And in Chrome everything is gravy, I apply the transitions and move elements within a parent container that has a background-image set and a background-attachment of fixed.
From what i've observed;
in safari whenever any sorts of transitions occur backface-visibility:hidden is attached to all elements on the page or certainly a number of ancestors or the target element.
backface-visibility:hidden; has a fairly undocumented issue when used in conjunction with background-attatchment:fixed; it will remove the background-image that is being fixed form view see here.
So therefore when any transitions occur anywhere on the page that involve opacity or 3d transforming my image flickers our and back in again when safari applys the backface-visibility effect.
Does anyone know a way around this issue?
Its rather annoying, and as I doubt apple will be updating for a while I'm hoping theres a solution.

List<StorageFile> files = new List<StorageFile>();
foreach (StorageFile file in (await ApplicationData.Current.LocalFolder.GetFilesAsync()))
if (Path.GetExtension(file.Name).ToLower() == ".item") files.Add(file);
return files;
}
catch (Exception e)
{
var x = e.Message;
return new List<StorageFile>();
}
When I step through, the offending statement is GetFilesAsync(), but I believe at the time I call it, there is no reason why it should fail. In any case, shouldn't my exception handler be called when something goes wrong?

I trying to detect the user clicks outside the element and remove the element from the DOM. Better i show you what appears to be the problem
HTML
<div class="worker-info">
<div (click)="showWorkersSelect = !showWorkersSelect" class="worker-name">
<fa-icon [icon]="['fal', 'user-circle']" size="1x"></fa-icon>
Worker name: <span>Anna</span>
<fa-icon class="select-worker-icon" [icon]="['fal', 'caret-down']" size="1x"></fa-icon>
</div>
<div #workerSelection @showWorkersSelect *ngIf="showWorkersSelect" class="select-worker-menu">
<div (click)="showWorkersSelect = !showWorkersSelect" class="select-worker-menu__worker-name">
Essti
</div>
<div (click)="showWorkersSelect = !showWorkersSelect"class="select-worker-menu__worker-name">
Ilana
</div>
</div>
</div>
So when the user clicks here
<div (click)="showWorkersSelect = !showWorkersSelect" class="worker-name">
The showWorkersSelect becoming true and the selection appers.
TS
@ViewChild('workerSelection') workerSelection: ElementRef
public showWorkersSelect = false
@HostListener('document:click', ['$event', '$event.target'])
onClick(event: MouseEvent, targetElement: HTMLElement): void {
if (this.showWorkersSelect) {
if (!targetElement) {
return;
}
const clickedInside = this.workerSelection.nativeElement.contains(targetElement);
if (!clickedInside) {
this.showWorkersSelect = false;
}
}
}
Here I want to run the method only when the selection is shown and close it after the user clicks outside, but the method closing it immediately after it opens
A: If your worker-selection has a z-index>0, You can use a "div" between with a z-index between 0 and z-index of worker-selection that cover all the screen
<div class="backscreen" *ngIf="showWorkersSelect" (click)="showWorkersSelect=false">
.backscreen {
position: fixed;
top: 0;
right: 0;
bottom: 0;
left: 0;
z-index: 1040; //<--use a z-index between 0 and z-index of selectWorker
background-color: transparent;
}

While I can access user data in my app, I am not able to see the same when I try to access while SQL command on the terminal. This problem is specific to the 'user' table, while other tables could be accessed normally on terminal too.
This is the result of my user query:
classroom=# SELECT * FROM user;
user
-------
fatih
(1 row)
and this is some other table in the same database:
classroom=# SELECT * FROM course;
id | title | code
----+-----------------------------+----------
3 | Algorithms | COC2030
4 | Web development using Flask | FLASK001
(2 rows)
I am expecting the same type of result as in the course table, as in the user table.
A: Assuming there are more columns or rows in the user table that you'd like to see, you could try:
*
*Log in using the same user as the flask app.
*Log in as user postgres and check if that changes things (sudo -u postgres psql classroom, or psql classroom postgres.)
*Use the \dp command to see if there are column privileges.
*Use the \dn+ command to see if there are row security policies.

So question is how to run commad tcc hello.c on windows command prompt using php script. php script & cmd.exe are on the came machine.
OS windows XP.
code that i want to compile is hello.c is given below.
php script that is executing hello.exe is also given below.
code from hello.c
#include<stdio.h>
void main(void)
{
printf("hello");
}
php code that is succefully accesing and displaying hello.exe
enter code here
<?php
echo "Remote compilation:";
$path = escapeshellcmd('C:\\TC\\BIN\\HELLO.exe');
passthru( $path, $return_var);
?>
please guide
regards
A: From the PHP documentation:
The passthru() function is similar to the exec() function in that it
executes a command. This function should be used in place of exec() or
system() when the output from the Unix command is binary data which
needs to be passed directly back to the browser.
But here you are not expecting binary data to be generated from tcc and passed to the browser. A more appropriate function to use would be shell_exec(). E.g.:
<?php
echo "Remote compilation:";
$command = escapeshellcmd('YOUR TCC COMPILE COMMAND HERE');
shell_exec($command);
?>

07-23 10:22:44.721 26585-26646/com.zspirytus.androidlua D/LuaEngine: getPkgData: 0028�ض
At Kotlin Layer, the result in String type is "0028"; at Jni Layer, the converted result is "0028�ض". The following is what I do in my code:
At Kotlin, the function return a bytearray:
fun getContentByEntryName(entryName: String): ByteArray {
// data is always a String with value "0028"
val data = ZipFileUtils.getFileContentFromZipFile(ZipFile(scriptPkg), entryName)
Log.d("ScriptPkgDataFetcher", "getPkgDatagetPkgData: $data at Kotlin")
return data.toByteArray()
}
At Jni, I convert jbytearray to char* like this:
jbyteArray jba = (jbyteArray) env->CallStaticObjectMethod(clazz, methodId, dataPath);
int len = env->GetArrayLength (jba);
char* buff = new char[len];
env->GetByteArrayRegion (jba, 0, len, reinterpret_cast<jbyte*>(buff));
Log_d(LOG_TAG, "getPkgData: %s", buff);
Seem that it is not work correct. I also try this code, but it still not
work correct...
jbyteArray jba = (jbyteArray) env->CallStaticObjectMethod(clazz, methodId, dataPath);
const char *cStr = (char *) (env)->GetByteArrayElements(jba, NULL);
Is any mistake existing in my code? Help me to correct it, Please. Thanks!
A: If you're going to use new char[] to create string data, and then use that data in functions that require null-termination, you have to explicitly add the null terminator.
In addition, you may not have allocated enough space for the terminating null, thus you need to allocate len + 1 bytes.
You can do this:
char* buff = new char[len + 1]();
which fills the buffer with null characters or:
char* buff = new char[len + 1];
buff[len] = '\0';
However I highly suggest you use a std::string or std::vector<char> instead of doing things this way.
Since JNI is very fragile, if an exception is thrown, you may get memory leaks using raw pointers this way.
Here is a small routine you can use to convert from a Java byte array to a vector:
#include <vector>
//...
jbyteArray jba = (jbyteArray) env->CallStaticObjectMethod(clazz, methodId, dataPath);
int len = env->GetArrayLength (jba);
std::vector<char> buff(len + 1, 0);
env->GetByteArrayRegion (jba, 0, len, reinterpret_cast<jbyte*>(buff.data()));
Log_d(LOG_TAG, "getPkgData: %s", buff.data());
This will not suffer from memory leaks if an exception is thrown, since std::vector will automatically deallocate the memory when the vector goes out of scope for any reason.

// I got a tiny model with only id loaded
$model = Model::first(['id']);
// Then some code runs
// Then I decide I'd need `name` and `status` attributes
$model->loadMoreAttributes(['name', 'status']);
// And now I can joyously use name and status without additional queries
$model->name;
$model->status;
Does Eloquent have something similar to my fictional loadMoreAttributes function?
Notice kindly that I'm not a novice and am very well aware of Model::find($model->id) and such. They're just too wordy.
Thanks for your attention in advance.
A: You may extend the Eloquent model to have this loadMoreAttributes method like so:
use Illuminate\Database\Eloquent\Model;
class YourModel extends Model
{
public function loadMoreAttributes(array $columns)
{
// LIMITATION: can only load other attributes if id field is set.
if (is_null($this->id)) {
return $this;
}
$newAttributes = self::where('id', $this->id)->first($columns);
if (! is_null($newAttributes)) {
$this->forceFill($newAttributes->toArray());
}
return $this;
}
}
This way you can do this on your model:
$model = YourModel::first(['id']);
$model->loadMoreAttributes(['name', 'status']);
LIMITATION
However there's a limitation to this hack. You may only call loadMoreAttributes() method if the unique id of your model instance is already fetched.
Hope this help!

I have a table and one of its column's data type is timestamp. I am trying to setup a DbParameter for this column. Looking at https://learn.microsoft.com/en-us/dotnet/framework/data/adonet/sql-server-data-type-mappings I can see that the DbParameter.DbType for this column should be Binary. But what should be the value of DbParameter.Size for this column?
Thanks
A: Sorry to read you got stuck in the past. I'll send Doc Brown to get you back to 2019. I mean, seriously, Don't you think it's high time to upgrade your VS and SQL Server?
To answer your question, In SQL Server, Timestamp is a synonym to RowVersion.
From documentation:
[rowversion] Is a data type that exposes automatically generated, unique binary numbers within a database. rowversion is generally used as a mechanism for version-stamping table rows. The storage size is 8 bytes. The rowversion data type is just an incrementing number and does not preserve a date or a time.
(emphasis mine)
Also, from the same documentation page:
Note
The timestamp syntax is deprecated. This feature is in maintenance mode and may be removed in a future version of Microsoft SQL Server. Avoid using this feature in new development work, and plan to modify applications that currently use this feature.
BTW, RowVersion is automatically generated - so unless your parameter is an out parameter, I see no reason to use it in a parameter.

I have used tooltip is similar fashion in lot of places throughout the application and all of them are working also..
I also tried adding it to the li and span still nothing happens

When placing a datagrid in first tab item, and binding to datatable,it works fine like so:
private void LoadServices()
{
if (serviceData.GetAllServices(currentID) != null)
{
dataGridServices.ItemsSource = serviceData.GetAllServices(currentID).DefaultView;
dataGridServices.Columns[0].Visibility = Visibility.Hidden;
}
}
(btw I am calling the method above in Window_ContentRendered event and it works fine).
I then add another datagrid in the second tabitem with the EXACT same code but now I get the error on the line below: "Index was out of range. Must be non-negative and less than the size of the collection. (Parameter 'index')'":
dataGridServices.Columns[0].Visibility = Visibility.Hidden;
When debugging and hovering over the ItemSource property, I can see that there are three columns there, so how can it be index out of range? By the way the method for binding to the second datagrid is the same as above and I am also calling this from Window_ContentRendered event too.
(Just to be clear, when I am not hiding the specific column, the data loads fine with the column names too which are defined in stored procedure)
Is there something unique in the way datagrids and tabcontrols work together in WPF?
LATEST CODE:
XAML:
<TabControl x:Name="tabControl">
<TabItem x:Name="FirstTabItem" Header="First">
<DataGrid x:Name="datagridServicesFirstTab">
</DataGrid>
</TabItem>
<TabItem x:Name="SecondTabItem" Header="Second">
<DataGrid x:Name="datagridServices" AutoGeneratedColumns="OnLoaded" >
</DataGrid>
</TabItem>
</TabControl>
Event Handler Method:
private void OnLoaded(object sender, EventArgs e)
{
LoadServices();
}
Data Method:
private void LoadServices()
{
if (serviceData.GetAllServices(currentID) != null)
{
datagridServices.ItemsSource = serviceData.GetAllServices(currentID).DefaultView;
datagridServices.Columns[0].Visibility = Visibility.Hidden;
}
}
A:
When debugging and hovering over the ItemSource property, I can see that there are three columns there, so how can it be index out of range?
Probably because the columns of the DataGrid has not yet been generated. The content of a tab item is not rendered until you select that tab.
Move your code from Window_ContentRenderer to a AutoGeneratedColumns event handler for the second DataGrid:
private void OnLoaded(object sender, EventArgs e)
{
LoadServices();
}
XAML:
<TabItem Header="second...">
<DataGrid ... AutoGeneratedColumns="OnLoaded" />

There should be something like "from execute" in the console because of this System.out.println("from execute"); but it does not go in the class
I don't know how to debug it anymore.
A: You have WEB-INF/class should be renamed to WEB-INF/classes. In the the package explorer right click on the folder name and choose rename or refactor/rename. If this doesn't work open a resource perspective and rename the folder name. After that clean and rebuild and redeploy the project.
A: what i did was to delete the saved jar in WEB-INF/lib i think my problems was because i had double jar one from the tutorial way and the other was because i had paste the same jar in the said folder.jar redundant my have cause my problem so if you have done the same delete the saved jar and rerun the program it will work for sure

From a related question, I implemented a very crude interface (untested) :
// server
const _cache = new Map();
const rooms = {
registerObserver: (roomHash, observer) => {
if (!_cache.has(roomHash)) {
_cache.add(roomHash, { messages:[], observers:[] );
}
const room = _cache.get(roomHash);
room.observers.add(observer);
observer.added("rooms", roomHash, { messages:room.messages });
observer.onStop(() => room.observers.delete(observer));
observer.ready();
}
}
Meteor.publish('chatroom', function (roomHash) {
check(roomHash, String);
rooms.registerObserver(roomHash, this);
});
Meteor.methods({
pushMessage: function (roomHash, message) {
check(roomHash, String);
check(message, String);
const room = _cache.get(roomHash);
room.messages.push(message);
room.observers.forEach(observer =>
observer.changed("rooms", roomHash, { messages:room.messags })
);
}
});
But, now, I need to fetch the messages from the given room, so I added :
// client, React hook
const useChatMessages = roomHash => {
const loading = useTracker(() => {
const handle = Meteor.subscribe("chatroom", roomHash);
return !handle.ready();
}, [orderHash]);
const pushMessage = useCallback(message => {
Meteor.call('pushMessage', roomHash, message);
}, [roomHash]);
const messages = []; // .... ???
return { loading, messages, pushMessage };
};
I have no idea how to fetch the messages. Since I removed the MongoDB dependencies, I do not have access to Mongo.Colllection, and it seems like Meteor.Collection is also unavailable (i.e. Meteor.Collection === undefined)
So, I publish, and also subscribe, but how do I fetch the published messages?
(Note: the above code compiles, but it is mostly untested as explained in the question.)

Does anyone have an Idea on how to fix it?
A: Installing JetBrains and opening your file in it once somehow fixes it.
It has no .NET MAUI support, but after you close the program and open Visual studio it somehow works again...
(Don't ask me how that works)

So, currently I have this
a-b-c-d
But I want this
a-b-c
\-d
How can I accomplish this?
This question has been marked as a duplicate of questions asking how to undo the last commit, but these do not answer my question because it's not the last commit I'm trying to undo but instead a commit twice back. Rebasing to HEAD{2} also doesn't work because that still undo's the last commit.
A: The easiest way:
*
*Remember the d's SHA1, let say it is 535dce28f1c68e8af9d22bc653aca426fb7825d8.
*git reset --hard HEAD~2
*git cherry-pick 535dce28f1c68e8af9d22bc653aca426fb7825d8
More advanced:
*
*git rebase -i HEAD~3
*Change the second pick to drop, or remove that line, then save the file and exit from the editor.
More advanced 2:
*
*git revert HEAD~1 will make b-c-d-^c
*git reset --soft HEAD~3 will reset to b and keep the changes on the disk
*git add -A && git commit will make b-d'.

Unfortunately, this won't work and I can't find a proper, elegant workaround.
The idea is, when adding a new animal category (e.g. birds), I just create a TemplateBird similar to TemplateMammals. When creating a new bird class, I will have only access to the proper methods, defined via class BirdStuff.
I can create a non-abstract methods in the animal category templates (e.g.
public MammalStuff getAnimalStuff{ return new MammalStuff()}
for TemplateMammals) but I don't like this, since I want to create a Framework and thus want to force the user to implement such a method.
Have you any idea for an elegant improvement? Or a complete other idea?
Thanks!
A: You could use a generic which is constrained to AnimalStuff.
public class Dog : TemplateMammals
{
public void SomethingWhereINeedStuff()
{
var stuff = GetAnimalStuff();
// stuff is of type MammalsStuff
}
}
public class TempalteMammals : TemplateAnimals<MammalsStuff>
{
public abstract MammalsStuff GetAnimalStuff() { ... }
}
public class TemplateAnimals<TStuff> where TStuff : AnimalStuff
{
public abstract TStuff GetAnimalStuff();
}
A: How about using generics?
AnimalStuff
In first step, we'll have the stuff defined and the Stuff must derive from a base Interface or Abstract class:
public interface AnimalStuff{
public void doAnimal();
}
Then you'll define your hierarchy as you want. I mixed abstract classes and interface but you can do full abstract classes or full interface until the implemented classes:
public abstract class MammalStuff implements AnimalStuff{
// no need to override unless there are mammal specific stuff
public void doAnimal(){...}
}
public abstract class BirdStuff implements AnimalStuff{
// example of bird specific
@Override
public void doAnimal(){
System.out.println("I believe I can fly!!!");
}
}
If I follow the exemple of a bird:
public class EagleStuff extends BirdStuff{
@Override
public void doAnimal(){
super.doAnimal();
System.out.println("But I also eat preys!!!");
}
}
Animal classes
Then you can create your Animals hierarchy:
public abstract class TemplateAnimal<S extends AnimalStuff> {
public abstract S getAnimalStuff();
}
With the hierarchy you defined. The generics definition is valid here because MammalStuff and BirdStuff extends (or implements) AnimalStuff
public abstract class TemplateMammal<S extends MammalStuff> extends TemplateAnimal<S>{
// no overriding here
// public abstract S getAnimalStuff();
}
public abstract class TemplateBird<S extends BirdStuff> extends TemplateAnimal<S>{
// no overriding here
// public abstract S getAnimalStuff();
}
Then, you'll have your Eagle:
public class Eagle extends TemplateBird<EagleStuff>{
@Override
public EagleStuff getAnimalStuff(){
// return ...
}
}
In the Eagle class, in you have the getAnimalStuff() with this signature public AnimalStuff getAnimalStuff(), it is illegal because the generic requires to return S type, not an AnimalStuff

wget --mirror --page-requisites --convert-link --no-clobber --no-parent --domains typingstudy.com https://www.typingstudy.com/
And wget creates directories, which contain html files on the site, only at the end of the scrapping and, accordingly, when it tries to download those html files, before the creation of the directories in which this files are located, wget says:powershell output
Sometimes it downloads only 1 file, like at this example, to the directory "part" and refuses to see this directory while trying downloading all other ~10 files from this exact directory, saying that this directory does not exist: enter image description here
Can someone help me understand what's wrong with my commands? Or is it a bug of wget?(Probably not)
Thanks in advance.
When I start the downloading process again - everything is neat, wget downloads all those ~10 other html files to created in the previous download session ("part") directories. So the problem is that I need to start the downloading 2 times, at least in case of this site.
And I totally do not understand why this is happening.

]},

{name: 'ParentTwo', children: [
{name: 'ParentTwoChildOne', children: [
{name: 'ParentTwoChildOneGrandChildOne'},
{name: 'ParentTwoChildOneGrandChildTwo'}
]},
{name: 'ParentTwoChildTwo'}
]}
];
I want to flatten it:
[
{name: 'ParentOne'},
{name: 'ParentOneChildOne'},
{name: 'ParentOneChildTwo'},
{name: 'ParentOneChildTwoGrandChildOne'},
{name: 'ParentTwo'},
{name: 'ParentTwoChildOne'},
{name: 'ParentTwoChildOneGrandChildOne'},
{name: 'ParentTwoChildOneGrandChildTwo'},
{name: 'ParentTwoChildTwo'}
]
I have tried _.flatten() and _.flatMap(), but it does not produce what I need. What is the best way to achieve it preferably using lodash.js or underscore.js.
A: Recursive functions is the way to go for any depth of iteration.
With some ES2015 and LoDash/Underscore
var arr = [{
name: 'ParentOne',
children: [{
name: 'ParentOneChildOne'
}, {
name: 'ParentOneChildTwo',
children: [{
name: 'ParentOneChildTwoGrandChildOne'
}, ]
}, ]
}, {
name: 'ParentTwo',
children: [{
name: 'ParentTwoChildOne',
children: [{
name: 'ParentTwoChildOneGrandChildOne'
}, {
name: 'ParentTwoChildOneGrandChildTwo'
}]
}, {
name: 'ParentTwoChildTwo'
}]
}];
var res = _.reduce(arr, (a, b) => {
(rec = item => {
_.each(item, (v, k) => (_.isObject(v) ? rec(v) : a.push(_.zipObject([k], [v]))))
})(b);
return a;
}, []);
console.log(res);
<script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.4/lodash.js"></script>
A: No need for underscore/lodash.
const arr = [
{name: 'ParentOne', children: [
{name: 'ParentOneChildOne'},
{name: 'ParentOneChildTwo', children: [
{name: 'ParentOneChildTwoGrandChildOne'},
]},
]},
{name: 'ParentTwo', children: [
{name: 'ParentTwoChildOne', children: [
{name: 'ParentTwoChildOneGrandChildOne'},
{name: 'ParentTwoChildOneGrandChildTwo'}
]},
{name: 'ParentTwoChildTwo'}
]}
];
function flatten(arr) {
return arr? arr.reduce((result, item) => [
...result,
{ name: item.name },
...flatten(item.children)
], []) : [];
}
console.log(flatten(arr));
A: I would use .reduce and recursion to do this. Here's my implementation using Array.reduce, but you could do much the same with underscore's reduce function.
const arr = [
{name: 'ParentOne', children: [
{name: 'ParentOneChildOne'},
{name: 'ParentOneChildTwo', children: [
{name: 'ParentOneChildTwoGrandChildOne'},
]},
]},
{name: 'ParentTwo', children: [
{name: 'ParentTwoChildOne', children: [
{name: 'ParentTwoChildOneGrandChildOne'},
{name: 'ParentTwoChildOneGrandChildTwo'}
]},
{name: 'ParentTwoChildTwo'}
]}
];
function flatten(arr) {
return arr.reduce((result, current) => {
if (current.children) {
const children = flatten(current.children);
delete current.children;
result.push(current);
result.push(...children);
} else {
result.push(current);
}
return result;
}, [])
}
console.log(flatten(arr));
A: You could try adapting the flatten function given in this answer, and slightly twist the logic to your object's structure.
//Your object
var data = [{
name: 'ParentOne',
children: [{
name: 'ParentOneChildOne'
},
{
name: 'ParentOneChildTwo',
children: [{
name: 'ParentOneChildTwoGrandChildOne'
}, ]
},
]
},
{
name: 'ParentTwo',
children: [{
name: 'ParentTwoChildOne',
children: [{
name: 'ParentTwoChildOneGrandChildOne'
},
{
name: 'ParentTwoChildOneGrandChildTwo'
}
]
},
{
name: 'ParentTwoChildTwo'
}
]
}
];
//georg's flatten function
flatten = function(x, result, prefix) {
if (_.isObject(x)) {
_.each(x, function(v, k) {
flatten(v, result, prefix ? prefix + '_' + k : k)
})
} else {
result[prefix] = x
}
return result
}
//using the function on your data
result = flatten(data, {});
console.log(result);
<script src="https://cdnjs.cloudflare.com/ajax/libs/underscore.js/1.8.3/underscore-min.js"></script>
Does this help at all?
A: You could use some destruction and use a recursive function for collecting all wanted items.
var array = [{ name: 'ParentOne', children: [{ name: 'ParentOneChildOne' }, { name: 'ParentOneChildTwo', children: [{ name: 'ParentOneChildTwoGrandChildOne' },] },] }, { name: 'ParentTwo', children: [{ name: 'ParentTwoChildOne', children: [{ name: 'ParentTwoChildOneGrandChildOne' }, { name: 'ParentTwoChildOneGrandChildTwo' }] }, { name: 'ParentTwoChildTwo' }] }],
flat = (r, { name, children = [] }) => [...r, { name }, ...children.reduce(flat, []) ],
result = array.reduce(flat, []);
console.log(result);
.as-console-wrapper { max-height: 100% !important; top: 0; }
On EDGE, you need a different use of default values.
var array = [{ name: 'ParentOne', children: [{ name: 'ParentOneChildOne' }, { name: 'ParentOneChildTwo', children: [{ name: 'ParentOneChildTwoGrandChildOne' },] },] }, { name: 'ParentTwo', children: [{ name: 'ParentTwoChildOne', children: [{ name: 'ParentTwoChildOneGrandChildOne' }, { name: 'ParentTwoChildOneGrandChildTwo' }] }, { name: 'ParentTwoChildTwo' }] }],
flat = (r, { name, children }) => [...r, { name }, ...(children || []).reduce(flat, []) ],
result = array.reduce(flat, []);
console.log(result);
.as-console-wrapper { max-height: 100% !important; top: 0; }

Is it possible to generate the triangulation in a manner that preserves the edges defined by the input vertices? (EDIT: i.e. a constrained Delaunay triangulation.) As can be done with the triangle package for Python.
For example, in the picture below there are several triangles (blue) that disregard the location of the edges (red) that are defined by the vertices. Is there a way to enforce these edges such that they are in all cases part of the triangulation result?
A: What you are looking for is called constrained Delaunay triangulation, and unfortunately the scipy.spatial implementation does not support it.
As you pointed out, triangle does have that feature -- why not use it instead?

Which tool would do the job the fastest / cleanest (sed, awk, perl, shell)?
A: Sed has a nice way of doing this:
sed -ne '2p' -e '4,6p'
for example:
$ printf '%s\n' {1..100} | sed -ne '2p' -e '4,6p'
2
4
5
6
A: Use awk and its parameter NR. You can compose conditional expressions such as:
$ cat a
aa
bb
cc
dd
ee
$ awk 'NR==3' a #print line number 3
cc
$ awk 'NR==3, NR==5' a #print from line number 3 up to number 5
cc
dd
ee
$ awk 'NR>2 && NR<7' a #print lines whose number is in the range (2,7)
cc
dd
ee
etc.
In your case,
$ awk 'NR==2; NR>=4 && NR<=6' a #print line number 2 and from 4 to 6
A: awk 'NR==2 || NR>=4 && NR<=6'
or
awk 'NR==2; NR==4,NR==6'
A: You can do it using just head and tail ...
For example:
NR=3; cat test.txt | head -n $NR | tail -n -1
extracts line 3 from test.txt; and
NB=2; NR=3; cat test.txt | head -n $(expr $NR \+ $NB) | tail -n -$NB
extracts line 3 to 5.
A: Use awk and keep it clear and simple:
awk 'NR==2 || (NR>=4 && NR<=6)' file

Seeing that all of my data was stored in strings on the server, I would like to create a method to convert all of the timestamps to Unix timestamps as an integer.
In other words, I need to convert:
{
"created_at" => "2015-01-18T00:58:58.903Z",
"updated_at" => "2015-01-18T00:58:58.903Z",
"user_id" => 1,
"status_id" => 1
}
to:
{
"created_at" => 1421542604,
"updated_at" => 1421542604,
"user_id" => 1,
"status_id" => 1
}
A: I wrote the following rspec, then realized I need to modify the default as_json method to perform this conversion:
expect(response_json).to eq(
{
'created_at' => user.created_at.as_json,
'updated_at' => user.updated_at.as_json,
'user_id' => user.user_id,
'status_id' => user.status_id
}
)
I then created /config/initializers/unix_timestamps.rb and it worked:
class ActiveSupport::TimeWithZone
def as_json
self.to_time.to_i
end
end

Everything works as expected when running the dev version.
Unfortunately when I do npm run build and run this via serve -s build my styles are not working.
The .css files are being found and compiled into a single minified version. But the problem is that the markup that is generated is having the class name prefixes changed to 'T-' instead of the prefix in the compiled .css file. (i.e) MyApp-header is getting changed to T-header, but in the minified css file, it still refers to MyApp-header.
prefix changed to T-
Any help would be appreciated.
A: This issue turned out to be caused by some nuance of using this...
@SuitCssify.decorator
I was evaluating this library for potential use in a project, and didn't discover this issue until trying to produce an actual production build.
I've since abandoned this approach and changed my configuration to use "CSS Modules" which are working out great. I would provide a link, but my reputation only allows me one link per post. ;(

How do you transition an AVplayer from a uitableviewcell to a new instance of a uiviewcontroller seamlessly?
A: I achieved this by implemnting the UIViewControllerTransitioningDelegate and using my own custom animator object, which conforms to the UIViewControllerAnimatedTransitioning protocol.
I used https://github.com/recruit-mp/RMPZoomTransitionAnimator as a reference, with a few modifications to move an actual view (not a snapshot) between source and destination UIViewControllers :
Within the animator object, using the animator object's delegate methods for "source frame" and "destiation frame" and "playerView", all which are implemented on the "to" and "from" view controllers, I grab the view containing the playing video, grab it's start frame, it's end frame, and properly animate the view from its start frame to the frame it will end up being located at on the "to" view controller.
Upon completion of the transition, I then add the playing video UIView as a subview to the destination view controller, so that it becomes part of the "to" view controller's view, available for interacting with, etc.

A: If you want to remove it dynamically only for certain circumstances you can try it with calling:
document.body.removeEventListener(type, listener[, options])
Here's a good read on removeEventListener
From the docs:
The EventTarget.removeEventListener() method removes from the EventTarget an event listener previously registered with EventTarget.addEventListener(). The event listener to be removed is identified using a combination of the event type, the event listener function itself, and various optional options that may affect the matching process; see Matching event listeners for removal
Syntax:
target.removeEventListener(type, listener[, options]);
target.removeEventListener(type, listener[, useCapture]);
Where type is your string which specifies the type of event for which to remove an event listener and listener is your EventListener-function of the event handler to remove from the event target.
If you want to remove it alltogether - just comment it out or delete it in your code as suggested in the comments..
A: This function works for me
$('#elementid').on('touchmove', function (e) {
e.stopPropagation();
});

cat ./file.txt | ./pargrep word
I tried to get the file name
fgets(buf, NULL, stdin);
How can I get just the file name instead of the file content, which I get when used gets. I need to read the file, which is pretty huge and need to read it twice.
A: I wouldn't use the pipe. I assume you are writing the program ./pargrep? I would pass the name of the file you want to process as the first argument to your pargrep program. The second argument would then be "word"
Then you would open the file by name in the program.
A: The problem is that cat outputs the contents of the file. If you want the filename, run as
echo ./file.txt | ./pargrep word
but better to use dernst suggestion rather than this

I have a div with some markdown in it
<div id="text">
> This is supposed to be a blockquote
1 < 2
</div>
and I'm converting it to HTML with this code
$(function () {
var sanitizer = Markdown.getSanitizingConverter();
var text = $("#text").html();
$("#text").html(sanitizer.makeHtml(text));
});
There is no blockquote, and the left angle bracket (<) in the code block is converted to <.
You can observe my problem on jsFiddle.
What do I have to do to fix this?
A: Use .text() when extracting the text from the DOM. .html() will encode some symbols as entities.
http://jsfiddle.net/fGNsM/3/
A: $(function() {
var $text = $('#text'),
convert = Markdown.getSanitizingConverter().makeHtml,
result = convert($text.text());
$text.html(result);
});

( requests

)
| union ( requests
| where timestamp > ago(-10m)
| summarize now = avg(duration)
)
I want to get the avg request duration of the last day and of the last 10 min.
I do it now in 2 different queries, but I like to have them in 1 query for performance.
When I run this query I get no response, I see the day and the now column, but it has no value.
A: from a query language perspective, what you're doing is valid and should work.
you should verify if you really intend to use the minus (-) sign in your call to the ago() function.
if you want the result in a single row, you can also use a join instead of a union
print ago(24h), ago(-24h)
will output:
| print_0 | print_1 |

For now, I want to get the data about the page Y.
To do this, I wrote following code:
final Facebook facebook = new FacebookFactory().getInstance();
facebook.setOAuthAppId("...", "...");
facebook.setOAuthAccessToken(new AccessToken("..."));
final AccessToken oAuthAccessToken = facebook.getOAuthAccessToken();
try {
final ResponseList<Page> pages = facebook.searchPages("Costume jewelry");
LOGGER.debug("oAuthAccessToken: " + oAuthAccessToken);
} catch (FacebookException e) {
LOGGER.error("", e);
}
When running this code, I get following exception:
22:56:38.405 [main] DEBUG f.internal.http.HttpResponseImpl - {"error":{"message":"Invalid OAuth access token.","type":"OAuthException","code":190}}
22:56:38.481 [main] ERROR c.a.f.FbCustomerProfiler -
facebook4j.FacebookException: message - Invalid OAuth access token.
code - 190
Relevant information for error recovery can be found on the Facebook Developers Document:
https://developers.facebook.com/docs/graph-api/using-graph-api/#errors
at facebook4j.internal.http.HttpClientImpl.request(HttpClientImpl.java:179) ~[facebook4j-core-2.1.0.jar:2.1.0]

Disconnected from the target VM, address: '127.0.0.1:50651', transport: 'socket'
I took those examples from the Facebook4J site. The only difference between my code and theirs is that in my version I do not call facebook.setOAuthPermissions(commaSeparetedPermissions);.
Therefore I suppose that missing permissions are the cause of the error.
What permissions do I need in order to run a query, which returns the data (most importantly - the ID of the page, which I can use in the next query) about a page?
A: To search for Pages, you need to pass an App Access Token with your request according to the Facebook docs:
https://developers.facebook.com/docs/graph-api/using-graph-api/v2.0#search
Searches across Page and Place objects requires an app access token.
You can use
{app_id}|{app_secret}
for that.
BTW, your original question "Find all people from city X, who like Y" will not work, because you're not able to query this kind of info from FB.

These two are passed in the header of the request.
The middleware class is the following :
from models import MongoToken
class TokenAuthenticationMiddleware(object):
def process_request(self, request):
if "HTTP_AUTHORIZATION" not in request.META:
return
tokenkey = get_authorization_header(request).split()[1]
token = MongoToken.objects.get(key=tokenkey)
user = User.objects.get(username=request.META.get("HTTP_USERNAME"))
if token.key == tokenkey and token.user.is_active:
request.user = user
request.token = tokenkey
I also put this in my MIDDLEWARE_CLASSES block of the settings.py files:
MIDDLEWARE_CLASSES = [
'corsheaders.middleware.CorsMiddleware',
'django.middleware.security.SecurityMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'django.middleware.common.CommonMiddleware',
'myproject.middleware.MongoAuthenticationMiddleware',
'myproject.middleware.TokenAuthenticationMiddleware',
'django.middleware.csrf.CsrfViewMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',
'django.middleware.clickjacking.XFrameOptionsMiddleware',
]
And when the considered view is reached, my token is here because thanks to the header params but the user is Null.
Then I am wondering if I did something wrong with this because it does not work.
Thank you for your help.
Alex.

CTRL + B : Set the highlighted text to bold, for example
What happens under the hood is, the <b> tag is attached or removed to the marked phrase, word whatever.
How is this done? Where do "they" know from, whether the element is already set to bold, and, primary question, where it is located?
I am asking this because i can't get rid of this problem, mentioned earlier today:
Get the highlighted text position in .html() and .text()
Edit:
I tried the following
Rich-Text-Editing
But first, it won't load correctly, but this should be caused by my own failure.
Second, for learning purposes, i would like to implent my own minified version.
As i am really at JavaScript, i could not figure out how this is be done.
A: document.getSelection() / window.getSelection() should work for whatever you'd like to do with the selected stuff.
Element styles get inherited. How this is kept track of depends on the CSS implementation.
Taking a look at the source code of Chrome might pretty much help.

We are facing a problem when the user was inactive for a time longer than the access token lifetime:
We suspect, that this is a configuration problem and we did not configure the CORS Header on one component correctly. Do we need to configure the CORS-Header on our Keycloak aswell? If so, how can we add the missing configuration?

Edit 1 [2020-04-30 10:45]
This is our current configuration. To eliminate problems regarding localhost, we entered our test machine's DNS name as web origin.
A: I guess you didn't configure Web Origins (that is not the same as Redirect URIs) in your OIDC client configuration in the Keycloak. You can use '*', because you are using http protocol.
I hope you know that https protocol is mandatory for OIDC flows and also that '*' is not valid Web Origin value for https protocol. So it is good idea to configure Web Origins explicitly, instead of wildcard for the future.
The best idea is to use already in dev:
*
*https, because it may work in dev on http, but then you will move to https in prod and it will be broken
*domain (you can "fake" it with local hosts file) instead of localhost, because some browsers may have a problem with localhost/127.0.0.1/...
A: this is actually is a bug in dotnet core.
try to add cors policy right in the "Configure" method.
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
app.UseRouting();
app.UseCors(option =>
option.AllowAnyOrigin()
.AllowAnyMethod()
.AllowAnyHeader()
);

Added custom markers on the map according to positions fetched from API.
I have displayed list of positions on UI. After click on position I want to replace that position's corresponding marker icon and reset all other icons.
Following code is not working as expected.
I have added this function to place markers on map:
placeMarkers(markers: any, infoWindowContent: any) {
// Display multiple markers on a map
let infoWindow = new google.maps.InfoWindow();
let bounds = new google.maps.LatLngBounds();
let marker;
// Loop through our array of markers & place each one on the map
for(let i = 0; i < markers.length; i++ ) {
let position = new google.maps.LatLng(<number>markers[i].lat, <number>markers[i].lang);
bounds.extend(position);
marker = new google.maps.Marker(<google.maps.MarkerOptions>{
position,
map: this.map,
title: markers[i].name,
icon: this.iconUrl,
});
// Allow each marker to have an info window
google.maps.event.addListener(marker, 'click', (function(marker, i) {
return function() {
infoWindow.setContent(infoWindowContent[i]);
infoWindow.open(this.map, marker);
}
})(marker, i));
// Automatically center the map fitting all markers on the screen
this.map.fitBounds(bounds);
}
}
And this code to replace marker of selected position:
selectSite(site: any, index: any) {
this.placeMarkers(this.finalMarkers, this.finalInfoWindowContent);
let selection = this.finalMarkers.find(function(item) {
return item.name == site.Name
});
let infowindow = new google.maps.InfoWindow();
let position = new google.maps.LatLng(<number>selection.lat, <number>selection.lang);
let redMarker = new google.maps.Marker(<google.maps.MarkerOptions>{
position: position,
map: this.map,
title: selection.name,
icon: {url: require('../../../assets/img/red-marker.png'), scaledSize: {height: 30, width: 20}}
});
redMarker.addListener('click', function() {
infowindow.setContent(selection.name);
infowindow.open(this.map, redMarker);
});
}
Above code is working fine initially, but got stuck after multiple location changes.
Any help is very much appreciated!
A: **You can Set Following marker**
var iconBase = 'https://maps.google.com/mapfiles/kml/shapes/';
var icons = {
parking: {
icon: iconBase + 'parking_lot_maps.png'
},
library: {
icon: iconBase + 'library_maps.png'
},
info: {
icon: iconBase + 'info-i_maps.png'
}
};
A: This is how I did it.
I simply did it outside google maps and it works great.

I've started mining on www.multiport.us and as such I am mining many different coins. Scrypt coins and sha-256.
I'd rather not have all my coins on Cryptsy or Vircuex, so I'm trying to get the Qt GUIs for each of the coins install compiled so I can have wallets on my PC.
Problem
I've been trying for several days now to get this stuff working and I just can't. I've tried with several different coins - Feathercoin, Novacoin, Namecoin, Worldcoin, Freicoin, Zetacoin, etc.
I have tried terminal, and Qt Creator, but I get different errors on each wallet, almost always missing program errors. I get missing bitcoin.cpp, missing QApplication, etc, etc. They just refuse to compile.
Fixes tried
In Qt Creator I have tried adding QT += Widgets, tried a couple of other things too.
In terminal I was originally using 'qmake', then 'make'. But that's been giving me various errors. Missing locale/****, or missing <QApplication>
I have been getting all my source files from the official SourceForge pages, and trying the latest releases and the "master" file list.
System
Ubuntu 13.10
qmake QMake version 3.0
Using Qt version 5.0.2 in /usr/lib/x86_64-linux-gnu
QTCreator version 2.7.1
Following the readme's and instructional files i have also installed the following dependancies
qt4-qmake
libqt4-dev
build-essential
libboost-dev
libboost-system-dev
libboost-filesystem-dev
libboost-program-options-dev
libboost-thread-dev \
libssl-dev
libdb++-dev
libminiupnpc-dev
libgmp3-dev
libmpfr-dev
I really don't know what the problem is. I'm guessing it has something to do with being on 13.10, either that or there is something major I'm just not seeing. But all the source files are the same, they are built so all you need to do is qmake and make, to compile on your own system and then run. But I'm just having no luck at all.
QT Creator is version 2.7.1 from the repository.
Here is the .pro file I'm using.
TEMPLATE = app
TARGET = bitcoin-qt
macx:TARGET = "Bitcoin-Qt"

INCLUDEPATH += src src/json src/qt

As I have said the instructions that all of the wallets I'm trying to compile come with say the exact same thing.
Bitcoin-Qt: Qt4 GUI for Bitcoin
===============================
Build instructions
===================
Debian
-------
First, make sure that the required packages for Qt4 development of your
distribution are installed, these are
::
for Debian and Ubuntu <= 11.10 :
::
apt-get install qt4-qmake libqt4-dev build-essential libboost-dev libboost-system-dev \
libboost-filesystem-dev libboost-program-options-dev libboost-thread-dev \
libssl-dev libdb4.8++-dev
for Ubuntu >= 12.04 (please read the 'Berkely DB version warning' below):
::
apt-get install qt4-qmake libqt4-dev build-essential libboost-dev libboost-system-dev \
libboost-filesystem-dev libboost-program-options-dev libboost-thread-dev \
libssl-dev libdb++-dev libminiupnpc-dev
then execute the following:
::
qmake
make
Alternatively, install `Qt Creator`_ and open the `bitcoin-qt.pro` file.
An executable named `bitcoin-qt` will be built.
.. _`Qt Creator`: http://qt-project.org/downloads/
Mac OS X
--------
- Download and install the `Qt Mac OS X SDK`_. It is recommended to also install Apple's Xcode with UNIX tools.
- Download and install either `MacPorts`_ or `HomeBrew`_.
- Execute the following commands in a terminal to get the dependencies using MacPorts:
::
sudo port selfupdate
sudo port install boost db48 miniupnpc
- Execute the following commands in a terminal to get the dependencies using HomeBrew:
::
brew update
brew install boost miniupnpc openssl berkeley-db4
- If using HomeBrew, edit `bitcoin-qt.pro` to account for library location differences. There's a diff in `contrib/homebrew/bitcoin-qt-pro.patch` that shows what you need to change, or you can just patch by doing
patch -p1 < contrib/homebrew/bitcoin.qt.pro.patch
- Open the bitcoin-qt.pro file in Qt Creator and build as normal (cmd-B)
.. _`Qt Mac OS X SDK`: http://qt-project.org/downloads/
.. _`MacPorts`: http://www.macports.org/install.php
.. _`HomeBrew`: http://mxcl.github.io/homebrew/
Build configuration options
============================
UPnP port forwarding
---------------------
To use UPnP for port forwarding behind a NAT router (recommended, as more connections overall allow for a faster and more stable bitcoin experience), pass the following argument to qmake:
::
qmake "USE_UPNP=1"
(in **Qt Creator**, you can find the setting for additional qmake arguments under "Projects" -> "Build Settings" -> "Build Steps", then click "Details" next to **qmake**)
This requires miniupnpc for UPnP port mapping. It can be downloaded from
http://miniupnp.tuxfamily.org/files/. UPnP support is not compiled in by default.
Set USE_UPNP to a different value to control this:
+------------+--------------------------------------------------------------------------+
| USE_UPNP=- | no UPnP support, miniupnpc not required; |
+------------+--------------------------------------------------------------------------+
| USE_UPNP=0 | (the default) built with UPnP, support turned off by default at runtime; |
+------------+--------------------------------------------------------------------------+
| USE_UPNP=1 | build with UPnP support turned on by default at runtime. |
+------------+--------------------------------------------------------------------------+
Notification support for recent (k)ubuntu versions
---------------------------------------------------
To see desktop notifications on (k)ubuntu versions starting from 10.04, enable usage of the
FreeDesktop notification interface through DBUS using the following qmake option:
::
qmake "USE_DBUS=1"
Generation of QR codes
-----------------------
libqrencode may be used to generate QRCode images for payment requests.
It can be downloaded from http://fukuchi.org/works/qrencode/index.html.en, or installed via your package manager. Pass the USE_QRCODE
flag to qmake to control this:
+--------------+--------------------------------------------------------------------------+
| USE_QRCODE=0 | (the default) No QRCode support - libarcode not required |
+--------------+--------------------------------------------------------------------------+
| USE_QRCODE=1 | QRCode support enabled |
+--------------+--------------------------------------------------------------------------+
Berkely DB version warning
==========================
A warning for people using the *static binary* version of Bitcoin on a Linux/UNIX-ish system (tl;dr: **Berkely DB databases are not forward compatible**).
The static binary version of Bitcoin is linked against libdb4.8 (see also `this Debian issue`_).
Now the nasty thing is that databases from 5.X are not compatible with 4.X.
If the globally installed development package of Berkely DB installed on your system is 5.X, any source you
build yourself will be linked against that. The first time you run with a 5.X version the database will be upgraded,
and 4.X cannot open the new format. This means that you cannot go back to the old statically linked version without
significant hassle!
.. _`this Debian issue`: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=621425
Ubuntu 11.10 warning
====================
Ubuntu 11.10 has a package called 'qt-at-spi' installed by default. At the time of writing, having that package
installed causes bitcoin-qt to crash intermittently. The issue has been reported as `launchpad bug 857790`_, but
isn't yet fixed.
Until the bug is fixed, you can remove the qt-at-spi package to work around the problem, though this will presumably
disable screen reader functionality for Qt apps:
::
sudo apt-get remove qt-at-spi
.. _`launchpad bug 857790`: https://bugs.launchpad.net/ubuntu/+source/qt-at-spi/+bug/857790
But when I try and compile with QT Creator or through terminal I get:
home/kun7/CoinMining/zetacoin-0.8.3/src/qt/bitcoin.cpp:5: error: QApplication: No such file or directory
I have found that lots of people are adding 'QT += widgets' to their .ro files and it fixes it, but when I do that I get:
/home/kun7/CoinMining/zetacoin-0.8.3/src/qt/bitcoin.cpp:122: error: 'setCodecForTr' is not a member of 'QTextCodec'
/home/kun7/CoinMining/zetacoin-0.8.3/src/qt/bitcoin.cpp:123: error: 'setCodecForCStrings' is not a member of 'QTextCodec'
/home/kun7/CoinMining/zetacoin-0.8.3/src/qt/bitcoin.cpp:123: error: 'codecForTr' is not a member of 'QTextCodec'
What am I missing?
A: The issue has been fixed!!!
I was a moron.
I was trying to run
qmake
make
But my system has qmake version 5 installed and i installed verion 4 as per the dependencies. So instead, to get the program to compile correctly, i need to force the use of version 4...
qmake-qt4
make
Voiala!!!!!

Any ideas?
A: I synced the device to my computer and examined the crash report. It said...
Dyld Error Message: Dyld Message: Library not loaded:

So, I'd not added one of the libraries.

I've got something like that http://jsfiddle.net/ot6fe3no/ but when I click rows are added in all tables.
Here is the code:
(function( $ ){
$.fn.tablaraize = function() {
var numShown = 5; // Initial rows shown & index
var numMore = 5; // Increment
var $table2 = $(this); // tbody containing all the rows
var $table = $(this).find('tbody'); // tbody containing all the rows
var numRows = $table.find('tr').length; // Total # rows
// Hide rows and add clickable div
$table.find('tr:gt(' + (numShown - 1) + ')').hide().end()
.after('<tbody id="more"><tr><td colspan="' +
$table.find('tr:first td').length + '"><div>Show more</div</tbody></td></tr>');
$table2.find('#more').click(function() {
numShown = numShown + numMore;
// no more "show more" if done
if (numShown >= numRows) {
$table2.find('#more').remove();
}
$table.find('tr:lt(' + numShown + ')').show();
});
}; })( jQuery );
$('table').tablaraize();
A: Just update your fiddle
(function( $ ){
$.fn.tablaraize = function() {
var numShown = 5; // Initial rows shown & index
var numMore = 5; // Increment
var $table2 = $(this); // tbody containing all the rows
var $table = $(this).find('tbody'); // tbody containing all the rows
var numRows = $table.find('tr').length; // Total # rows
// Hide rows and add clickable div
$table.find('tr:gt(' + (numShown - 1) + ')').hide().end()
.after('<tbody id="more"><tr><td colspan="' +
$table.find('tr:first td').length + '"><div>Show more</div</tbody></td></tr>');
$table2.find('#more').click(function() {
numShown = numShown + numMore;
// no more "show more" if done
if (numShown >= numRows) {
$table2.find('#more').remove();
}
// $table.find('tr:lt(' + numShown + ')').show(); this will run on all table
$(this).parent("table").find('tr:lt(' + numShown + ')').show(); // show the rows of current clicked
});
}; })( jQuery );
$('table').tablaraize();
fiddle link
A: Thanks for help, it's working but I found two problems:
1. Show more is not disapearing when all rows are visible, I fix it with:
// no more "show more" if done
if (numShown+1 >= numRows) {
//$table2.find('#more').remove();
$(this).parent("table").find('#more').remove();
}
*When there is 2 rows - Show more is appearing, I cant find the way the way around this

I have created below file:
.ebextentions/nginx/conf.d/myapp.conf
And I added the below content based on this article:
server {
if ($http_x_forwarded_proto != 'https') {
rewrite ^(.*) https://$host$1 redirect;
}
}
I have installed SSL certificate in certificate manager and set it in my environment. Now the application serves both HTTP and https request. I want to redirect all HTTP requests to https without falling into a redirect loop. but doesn't work.
A: I don't think you should add the server part to the .conf file. The entire .conf file should be something like this:
if ($http_x_forwarded_proto = 'http') {
return 301 https://www.example.com$request_uri;
}
See this answer on Server Fault.

A: That is an embedded copy of the ConcurrentLinkedHashMap library. The tutorial provides an example using an EvictionListener and can be written as,
ConcurrentMap<K, V> cache = new ConcurrentLinkedHashMap.Builder<K, V>()
.maximumWeightedCapacity(3_000)
.listener((key, value) ->
System.out.printf("Evicted key=%s, value=%s%n", key, value))
.build();
While this library is small and nibble, it was written in the Java 5 timeframe. It is still excellent for embedded cases to minimize the jar size, but general purpose usages should prefer Caffeine instead. That library provides a richer feature set and additional performance improvements.
Cache<K, V> graphs = Caffeine.newBuilder()
.maximumSize(3_000)
.removalListener((K key, V value, RemovalCause cause) ->
System.out.printf("%s: key=%s, value=%s%n", cause, key, value))
.build();

I want filter the people in my cohort have completed a certain measure at at least 3 time points out of a potential 8, i.e., DO NOT have missing data for at least 3 time points. Except for the first year, It doesn't matter which of those 3 time points they completed, it just needs to be three total. So, how do I say to R:
Please return me back participants who have participated in 3 or more of the following: Y1_Q-Sort AND ANY OF THE FOLLOWING 2 OR MORE: Y2_Q-Sort, Y3_Q-Sort, Y4_Q-Sort, Y5_Q-Sort, Y6_Q-Sort, Y7_QSort, and Y8_QSort.
Thank you so much for your help!

User case: an user establishes a connection to a server. I create a WebSocket object and put it into webSocketInstance. When an user enters his usename I add the name to Redux and it causes re-render of the component which is okay. Now as he has the username I want him to reconnect with a new url(also this part of reconnection logic). So I want him to close the previous connection and open a new one.
export default function GameKeeper() {
// Redux states here
const { adminWsUrl, clientWsUrl, clientCode, playerName } = useSelector(
(state: RootState) => state.hosting
);
const [webSocketInstance, setWebSocketInstance] = useState<WebSocket>();
useEffect(() => {
if (webSocketInstance) {
webSocketInstance.close();
}
if (adminWsUrl) {
setWebSocketInstance(new WebSocket(adminWsUrl));
} else if (clientWsUrl && playerName) {
setWebSocketInstance(new WebSocket(`${clientWsUrl}${playerName}/`));
} else if (clientWsUrl && !playerName) {
setWebSocketInstance(new WebSocket(clientWsUrl));
}
}, [adminWsUrl, clientWsUrl, playerName]);
return (
...
);
}
The current code gives me a warning that webSocketInstance is not in useEffect dependencies. If I add it, I get infinite loop.
A: Here's a basic template for how I'd go about setting up a useReducer to handle this. I can't really think of a good way to do this with just useState without also utilising some mutative state (i.e. useRef) to hold the Web Socket instead. The drawback there of course is you've escaped React's state system altogether and can no longer watch your socket for updates.
function wsReducer(wsInstance, action) {
if (action.type === "reset") {
wsInstance && wsInstance.close();
return new WebSocket(action.payload);
}
}
export default function App() {
const { adminWsUrl, clientWsUrl, clientCode, playerName } = useSelector(
(state: RootState) => state.hosting
);
const [wsInstance, dispatch] = useReducer(wsReducer, null);
useEffect(() => {
const url = (() => {
if (adminWsUrl) return adminWsUrl;
if (clientWsUrl && playerName) return `${clientWsUrl}${playerName}/`;
if (clientWsUrl && !playerName) return clientWsUrl;
return false;
})();
if (url) {
dispatch({ type: "reset", payload: url });
}
}, [adminWsUrl, clientWsUrl, playerName]);
return (
...
);
}
Also, some recommended reading - particularly the stuff on decoupling updates/actions and using useReducer in this context. I'd suggest trying to get through the whole thing, it was really useful for me when I started doing functional React.

A: It appears that your api key was invalid and your jar imports were conflicting with each other. You have to make sure you are making that call inside an AsyncTask. After that, all is going to work ok.

A: You can use the date_part function, like this:
date_part('hour', timestamp '2001-02-16 20:38:40')
This would give you 20 for example.
For more information, refer to http://www.postgresql.org/docs/8.2/interactive/functions-datetime.html
A: Not sure what you exactly mean. Perhaps answer to your question is:
select now();
or maybe it's:
select now()::time;
A: Maybe:
select to_char (field, 'HH24:MI:SS') FROM table;
Example:
select to_char ('2011-04-13 11:22:33'::timestamp, 'HH24:MI:SS');
It gives you:
11:22:33

A: You're defining a nested serializer and provide flat data.
If you want to keep data flat, you'll only need one serializer and add the extra fields to it:
class ValidateMeUserSerializer(serializers.ModelSerializer):
username = serializers.CharField(...)
email = serializers.CharField(...)
password = serializers.CharField(...)
class Meta:
model = ValidateMeUser
fields = ('mobileNumber', 'username', 'email', 'password')

username = validated_data.pop('username')
...
user = User.objects.create_user(username=username, ...)
validateMeUser = ValidateMeUser.objects.create(user=user, **validated_data)
return validateMeUser

The user is going to enter a word and then hit enter... How do i capture that into an array of chars? If the word was coming in one char at a time I could just add it to the array, dynamically expanding if needed, but when it comes in a block of char's like that I am lost for ideas. Thanks!
A: The member function cin.getline() allows you to specify a character buffer and length.
char name[32];
cin.getline(name, 32);
Though any C++ assignment that would ask you specifically to use character arrays instead of strings (especially in this context), is suspect.
A: Try this:
char arr[100];
cin >> arr;

A: You can use the following:
Joomla 2.5:
$parser = JFactory::getXMLParser('Simple');
$xml = JPATH_SITE .'/components/com_wrapper/wrapper.xml';
$parser->loadFile($xml);
$doc = $parser->document;
$element = $doc->getElementByPath('version');
$version = $element->data();
echo $version;
Joomla 3.x (Platform 13.3 and below)
$xml = JFactory::getXML(JPATH_SITE .'/components/com_wrapper/wrapper.xml');
$version = (string)$xml->version;
echo $version;
Joomla 3.2+:
getXML was made deprecated as of 2 weeks after this answer. Instead, use SimpleXML
Obviously this is an example for the Wrapper component so change the paths to whatever suits your needs.
Hope this helps
A: If you are looking for a listing of all components within your Joomla site, you can find them by using the Extension Manager -> Manage and select type filter "Components". This will give you a listing with a Version column showing the versions of all the Components.
That's an answer to your original question without coding.
A: Based on the answer of CoalaWeb, but with less code (more code use from the framework):
/** @var JTableExtension $extension */
$extension = JTable::getInstance('extension');
$id = $extension->find(array('element' => $extension));
$extension->load($id);
$componentInfo = json_decode($extension->manifest_cache, true);
return $componentInfo['version'];
A: Joomla 1.5, 2.5, 3.X.
We are using different XML files for Joomla 1.5 (com_ponent.xml) and for 2.5, 3.X (_manifest.xml) versions.
Using SimpleXML :
public static function getVbssoVersion() {
$xml_path = JPATH_ADMINISTRATOR . '/components/com_ponent/';
$xml_path .= (defined('JVER') && JVER == '1.5') ? 'com_ponent.xml' : '_manifest.xml';
$xml_obj = new SimpleXMLElement(file_get_contents($xml_path));
return strval($xml_obj->version);
}
A: To fully leverage the Joomla API, use the JComponentHelper, \Joomla\Registry\Registry and JTable classes:
$component = \JComponentHelper::getComponent('com_myextension');
$extension = \JTable::getInstance('extension');
$extension->load($component->id);
$manifest = new \Joomla\Registry\Registry($extension->manifest_cache);
echo $manifest->get('version');
This applies mainly to newer 3.x versions of Joomla; 3.6+ probably.
A: Joomla 3.2+:
Because getXML is deprecated, you could use SimpleXML in the following way:
$xml = simplexml_load_file(JPATH_COMPONENT_ADMINISTRATOR . '/wrapper.xml');
$version = $xml->version;
A: Hi I use this function to return versions from the extensions table based on element (I find its more reliable than name) but you could easily substitute element for name.
I have this in a plugin and the function only needs the element($ext) to check against the current extension in the table.
function extversion($ext) {
$db = JFactory::getDbo();
$query = $db->getQuery(true);
$query->select('manifest_cache');
$query->from($db->quoteName('#__extensions'));
$query->where('element = "' . $ext . '"');
$db->setQuery($query);
$manifest = json_decode($db->loadResult(), true);
return $manifest['version'];
}

Empty array : [ {0: undefined} ]
Full array :
[
{0: "Name"},
{1: "img.src"},
{2: name: string, family: string, age: number}
]
0: "Name" , 1: "img.src" 2 {name: string, family: string; age: number}
My try which isn't working :
<div *ngFor="let fam of familyArray" class="grid-item">
<button ion-button>
<img *ngIf="fam[1] != undefined && fam[1] != null " class="selectImg" src="{{fam[1]}}" alt="">
</button>
<span *ngIf="fam[2].name != undefined && family[2].age != undefined && family[2].age != null && family[2].name != null " class="image-text">{{fam[2].name}}, {{family[2].age}}m.</span>
<p *ngIf="fam[2].family != undefined && fam[2].family != null " class="family-status">{{fam[2].family}}</p>
</div>
I always get this errors :
TypeError: Cannot read property '1' of undefined
or
TypeError: Cannot read property 'name' of undefined
A: You don't need to put checks for undefined and null, It take cares it self for undefined and nulls, you just need to specify like below:
<div *ngFor="let fam of familyArray" class="grid-item" >
<button *ngIf="fam[0]" ion-button>
<img *ngIf="fam[1]" class="selectImg" src="{{fam[1]}}" alt="">
</button>
<span *ngIf="fam[2] && fam[2].name && family[2].age" class="image-text">{{fam[2].name}}, {{family[2].age}}m.</span>
<p *ngIf="fam[2].family" class="family-status">{{fam[2].family}}</p>
</div>
The array of object which you are receiving is actually a wrong format, all the object should be in same types and some standard conventions need to be followed though.
A: <div *ngFor="let fam of familyArray" class="grid-item">
<button ion-button>
<img *ngIf="fam['1'] != undefined && fam['1'] != null " class="selectImg" src="{{fam['1']}}" alt="">
</button>
<span *ngIf="fam['2'].name != undefined && family['2'].age != undefined && family['2'].age != null && family['2'].name != null " class="image-text">{{fam['2'].name}}, {{family['2'].age}}m.</span>
<p *ngIf="fam['2'].family != undefined && fam['2'].family != null " class="family-status">{{fam['2'].family}}</p>
</div>
Above code 3 times as there are 3 objects in your array.
First time value of fam is {0: Name},
Second time {1: img.src},
and third time {2: name: Example, family: example, age:15}
there is not such object fam[1]
I hope I have explained enough.
A: Fixed it by doing this :
HTML (added ngIf to the button) :
<div *ngFor="let fam of familyArray" class="grid-item" >
<button *ngIf="familyArray[0] != undefined " ion-button>
<img *ngIf="fam[1] != undefined && fam[1] != null " class="selectImg" src="{{fam[1]}}" alt="">
</button>
<span *ngIf="fam[2].name != undefined && family[2].age != undefined && family[2].age != null && family[2].name != null " class="image-text">{{fam[2].name}}, {{family[2].age}}m.</span>
<p *ngIf="fam[2].family != undefined && fam[2].family != null " class="family-status">{{fam[2].family}}</p>
</div>
And made that my array would be empty, not 0:undefined if nothing is there.
A: You had added the additional checks for undefined and null and missed the check in couple of places.
Here is the working copy of your example -
https://stackblitz.com/edit/angular-e8zjsq
A: ` <div class="count-section" fxLayout="row">
<span fxFlex="13.3%" >Super cell: <b>{{countAnalysisDrugInfo[2].value}}</b></span>
<span fxFlex="12.3%" >Locking cell: <b>{{countAnalysisDrugInfo[0].value}}</b></span>
<span fxFlex="12.3%" >Regular cell: <b *ngIf="countAnalysisDrugInfo[4]">{{countAnalysisDrugInfo[4].value}}</b></span>
<span fxFlex="16.3%" >Super locking cell: <b>{{countAnalysisDrugInfo[3].value}}</b></span>
<span fxFlex="12.3%" >Schedule ll: <b>{{countAnalysisDrugInfo[0].value}}</b></span>
<span fxFlex="12.3%" >Schedule lll: <b>{{countAnalysisDrugInfo[1].value}}</b></span>

A: It is best to initialize a new Git repo locally in command-line first:
cd /path/to/new/folder
git init .
# Add some project files, including at least one with `__init__.py`
(see "Import directory into pycharm")
Then import that folder into PyCharm.

Link to site: http://christap4.sg-host.com
A: From your link this is what I came up with.
body { margin: 0 } /* this is just for the snippet, ignore it */
<video id="wp-custom-header-video" autoplay="" loop="" playsinline="" src="http://christap4.sg-host.com/wp-content/uploads/2022/06/2AE-Hero-Video-20220616.mp4" style="width: 100vw;height: auto;opacity: 1;aspect-ratio: 1.77777778;"></video>
To get 100% of the screen width you can use width: 100vw (vw = viewport width). I've also included ascpect-ratio: 1.77777778 (video width / video height) and then set the height to auto
A: Looks like there are a couple of things here.
Looking at your output it looks like you have over-complicated the solution. Anything that is position absolute with 100% width will be as wide as it's most relative parent (by default the body).
If you set the width to 100% you can set the height using aspect-ratio ( https://developer.mozilla.org/en-US/docs/Web/CSS/aspect-ratio ). I'm not sure how far back you are going in browser support but this will cover most uses.
Alternatively you can give it a fixed height and use object-fit cover but this will cause some cropping.
The poster image will just inherit the same dimensions as the video. That being said short videos can now autoplay providing they are the right format, muted and have the right attributes set on them.

var NFA = function(par) {
this.stack = [];
this.op_stack = [];
this.parent = par;
};
NFA.prototype.parse = function(pattern) {
var done = false;
for(var i in pattern) {
if (done === true) {
break;
}
switch(pattern.charAt(i)) {
case "(":
var sub_nfa = new NFA(this);
this.stack.push(sub_nfa);
sub_nfa.parse(pattern.substring(i+1, pattern.length));
done = true;
break;
case ")":
if (this.parent !== null) {
var len = pattern.length;
/*TROUBLE SPOT*/
this.parent.parse(pattern.substring(i, pattern.length));
done = true;
break;
}
case "*":
this.op_stack.push(operator.KLEENE);
break;

this.op_stack.push(operator.UNION);
break;
default:
if(this.stack.length > 0) {
//only push concat after we see at least one symbol
this.op_stack.push(operator.CONCAT);
}
this.stack.push(pattern.charAt(i));
}
}
};
Note the area marked "TROUBLE SPOT". Given the regular expression "(a|b)a", the call this.parent.parse, is called exactly once: when the sub-automaton encounters ")". At this point, pattern.substring(i, pattern.length) = ")a". This "works", but it isn't correct because I need to consume the ")" input before I pass the string to the parent automaton. However, if I change the call to this.parent.parse(pattern.substring(i+1, pattern.length), parse gets handed the empty string! I have tried stepping through the code and I cannot explain this behavior. What am I missing?
At Juan's suggestion, I made a quick jsfiddle to show the problem when trying to parse "(a|b)a" with this algorithm. In the ")" case, it populates an empty div with the substring at the i index and the substring at the i+1 index. It shows that while there are 2 characters in the substring at i, the substring at i+1 is the empty string! Here's the link: http://jsfiddle.net/XC6QM/1/
EDIT: I edited this question to reflect the fact that using charAt(i) doesn't change the behavior of the algorithm.
A: I think the previous answer was on the right track. But there also looks to me to be an off-by-one error. Shouldn't you be increasing the index for your substring? You don't want to include the ")" in the parent parse, right?
this.parent.parse(pattern.substring(i + 1, pattern.length));
But this will still fail because of the error Juan mentioned. A quick temporary fix to test this would be to convert the i to a number:
this.parent.parse(pattern.substring(+i + 1, pattern.length));
This might do it for you. But you should probably go back and switch away from the for-in loop on the string. I think that's causing your issue. Turn it into an array with str.split('') and then use an integer to loop. That will prevent further such issues.
A: The real problem is the fact that you were using a for in to iterate through the characters of the string. With the for in loop, your i is going to be a string, therefore, when you try to do i+1, it does string concatenation.
If you change your iteration to be
for(var i=0; i < pattern.length; i++) {
Then it all works fine http://jsfiddle.net/XC6QM/2/
Scott's answer correctly identified the problem but I think his solution (converting the indexes to numbers) is not ideal. You're better off looping with a numeric index to begin with
Also, you should not use brackets to access characters within a string, that does not work in IE 7
switch(pattern[i]) {
should be
switch(pattern.charAt(i)) {

I know how the event-mechanism works and what the recommended ways of using are. Works well.(Note: My application is single-threaded)
What I want to is, to set a value to a property in my EventArgs. I've never had the need to set properties there.
This is a simplified situation of my current situation: (Note, I don't need answers telling me to use regex, or stringreplace, because that won't work in this situation)
I have this EventArgs:
public class TestEventArgs : EventArgs
{
public String OldString { get; private set; }
public String NewString { get; set; }
public TestEventArgs(String oldString)
{
this.OldString = oldString;
}
}
I do normally raise events this way:
public event EventHandler<TestEventArgs> ChangeString;
protected virtual void OnChangeString(String oldString)
{
EventHandler<TestEventArgs> handler = this.ChangeString;
if (handler != null)
{
handler(this, new TestEventArgs(oldString));
}
}
and by calling the OnChangeString method, because I read that this in the way to raise events a long time ago.
Modified code where I need a value of the EventArgs after it's been raised:
public event EventHandler<TestEventArgs> ChangeString;
protected virtual void OnChangeString(TestEventArgs args)
{
EventHandler<TestEventArgs> handler = this.ChangeString;
if (handler != null)
{
handler(this, args);
}
}
public void Foo()
{
String oldString = "this is the old string";
// this.OnChangeString(oldString) // this is the way I called before
// now I need to keep a reference to the EventArgs
TestEventArgs args = new TestEventArgs(oldString);
this.OnChangeString(args);
// here I do have full access to args.NewString
}
So, is it ok to keep a reference for the EventArgs and to raise the event with a method that accepts my EventArgs as parameter?
A: I think your question boils down to:
Is it OK to use the the arguments of an event to communicate data back to the source of the event?
First and foremost: at the low level, this will work. You can modify the event object, and you can see those changes in the code that raises the event.
But what if there are multiple event listeners. Who gets to set NewString?
If you expect only one, it is more clear to pass a delegate (of type Func<String, String>) to the class that now raises the event.
A: If I get your question right, you generally don't want to keep a reference to your TestEventArg, and reuse this object on another event.
In your case, your TestEventArg has a public properties call NewString. If any event handler updates this property, while it is begin reference by multiple part of your program, you may accidentally running into problem where the NewString property kept changing from another part of your problem.
However, if your TestEventArg has only readable property, then I see no problem keeping the reference and reuse it.
public class TestEventArgs : EventArgs
{
public String OldString { get; private set; }
public String NewString { get; private set; }
public TestEventArgs(String oldString, String newString)
{
this.OldString = oldString;
this.NewString - newString
}
}
In general, you want to keep your event arg immutable which will makes your program easier understand and debug.
A: Only time I keep the TestEventArg arg (in this case) is if you need access to the variable after the method has been called. Example of this is the OnClosing event for a Form. It has a variable you can set to tell it to cancel the close. In this case, if the client registers the callback, and can set a property on the TestEventArg class, then you'd want to have a variable pointed to it. If all you want to do is pass information to the callback and don't need anything back, then the first method is what I use.
One caveat for me is that if I use the OnChangeString method, I write it so that it encapsulates the details of the event args.
protected virtual void OnChangeString(string oldString)
{
EventHandler<TestEventArgs> handler = this.ChangeString;
if (handler != null)
{
var args = new TestEventArgs(oldString);
handler(this, args);
// Do something with args
}
}

Compiler --> avrdude --> Ethernet port of the compiler host PC --> Ethernet port of a Raspberry Pi --> Pins of the Raspberry Pi --> avr microcontroller
My question is about the code which I should run on the Raspberry Pi to do all the work required on that side. I'm guessing in this specific example it's possible to install avrdude on the Raspberry Pi and pipe the compiled code from the PC to the avrdude on the pi but I'm looking for a general solution that can be used with all microcontrollers, essentially turning the Raspberry Pi into a transparent, Ethernet connected, USB to TTL converter, either existing libraries or directions to how to write such code and where to read the documentations.
Edit1: There's a C language library called pigpio already installed on the Raspberry Pi OS and it can output UART. But I don't know how to read the USB data coming to the Raspberry Pi through its Ethernet port and convert it to UART data.
Edit2: I Changed USB port to Ethernet port since you can't connect two computers directly through USB. The data coming from the PC is still intended for USB to TTL converters since that's how avrdude and similar softwares are written(I guess it'll be "USB over Ethernet").

Not sure what is happening can any one please help
A: use str to invoke maketrans
LETTERS = 'abcdefghijklmnopqrstuvwxyz'
NUMBERS = '22233344455566677778889999'
## translate a-z char to phone digits
TRANS = str.maketrans(LETTERS, NUMBERS)
A: In Python2, maketrans is a function belongs to the string module. However in Python3, maketrans is a static method of the str type.
A: Update: petl >= 1.0 supports Python 3.4.
Clearly petl does not work on Python 3.x.
This specific error is because the Python 2.x string.maketrans function doesn't exist in 3.x.* But if you got past that, you'd find lots of other errors.
While the PyPI entry doesn't list supported versions (which it really should), a quick google turned up Issue #240, to add Python 3 support, which has been on the backlog since 26 Aug 2014. And a 2to3 pass over the source shows hundreds of issues.**
So, how do you fix this?
*
*Use something other than petl.
*Use Python 2.7 for your petl work.
*Help port it.
* Actually, in 3.0, it still existed, but only worked on bytes objects. In 3.1, maketrans and translate methods were added to bytes and bytearray, equivalent to the ones on str, and the string functions were deprecated, and then in 3.2 or 3.3 they were removed.
** Some of these issues are using things that were already deprecated in 2.6 or 2.7, which is odd given that petl originally worked only in 2.7, and was later ported to also work in 2.6.
A: Because I was looking for a clear example of how it works in python 3.4, I post what I've found:
#in py2 you need to "from string import maketrans"
table = "".maketrans('cs', 'kz')
#py2 table = maketrans('cs', 'kz')
len(table)
#in py2 you will get **len(table) = 256 in py3.4 len(table) = 2**
sentence = "cause koala is causing trouble"
sentence.translate(table)

Here is what I have
<?php if (!empty($content['relationship_graph'])){
print render($content['relationship_graph']);
echo '<hr>';
}
?>
Not very pro in PHP but looked at some documentation...Cant seem to figure out what I might be doing wrong
A: Value in it could be a blank space.
try..
<?php
if(!empty($content['relationship_graph']) && $content['relationship_graph']!=''){
print render($content['relationship_graph']);
echo '<hr>';
}
?>
A: Here is what I ended up doing. It worked.
if($content['relationship_graph']['#markup']['length'] != 0){
print render($content['relationship_graph']);
echo '<hr>';
}

The problem I am running into is that Glass occasionally moves the focus to the button. As a result, a tap keeps activating the button.
It seems Glass automatically converts toolbar menu items to live cards when top-to-bottom swing is used. This is nice. It gives the users the ability to select a menu item.
I am thinking if I could set the default state of the button to "disabled," it could solve my problem. However, this also results in disabling the button in the live cards. I would like to enable the button only during live cards.
Is there a way to achieve this? Or, is there a better way to remove focus out of the toolbar? Regards.

However, I want to create a UI in django framework which consist of a 'start' and a 'stop' button. What should I do to stop the twython streaming when I clicked on the button 'stop' ? Can give me some simple examples pls?
A: As long as the stop button is bound to the rest of the app (I haven't used Django, so I can't provide a simple example) then calling sys.exit() should do the job.
Django might have some other method for terminating a process built into it or some specific examples in its documentation. You should check that to confirm this answer.
A: You can use the disconnect() function as described in the documentation of Twython - https://twython.readthedocs.org/en/latest/api.html#twython.TwythonStreamer.disconnect
def on_stop(self, status_code, data):
self.disconnect()
def on_start(keywords):
stream = MyStreamer(cred['consumer_key'], cred['consumer_secret'],
cred['access_token_key'], cred['access_token_secret'])
stream.statuses.filter(track=keywords)

I would do something like this :
s---> A | empty string
A---> aB| empty String
b---> Ab
but How do we keep count of the number in the grammar? meaning How does it know when there are more that 100 a's. Also I'm not even sure if my way makes sense.
Any help would be appreciated.
A: As the members of this language are clearly limited, you can just give them as a listing of all possible cases:
S -> ab | aabb | aaabbb | ... | a^100b^100
A: Let's say that S is the start symbol:
1) S -> aXb
2) X -> aXb
3) X -> ab
And I can prove this works:
1) S -> aXb
2) aXb -> a aXb b
... (n-3) times
a^(n-1) X b^(n-1) -> a^n b^n (using the third rule, X -> ab)

void getWord(char words[][MAXWORDLENGTH]){
int i;
char newWord[MAXWORDLENGTH];
FILE* file;
file = fopen("wordbank.txt","r");
if(file==NULL){
printf("Error\n");
}else{
printf("File read\n");
for(i=0;i<=MAXWORDS;i++){
fgets(newWord, "%s", file);
printf("newWord: %s", newWord);
strcpy(words[i], newWord);
}
}
fclose(file);
}
Unfortunately my array "words" does not fill each element with a string, it is able to capture the first word in my text file into the [0] element and then the rest is gibberish.
my text file looks like this:
apple
winter
summer
skunk
clouds
pencil
grape
Would it be easier for me to use a pointer instead of an array?
Thanks for the help!
A: Alright, you may be making things more difficult than they need to be. The comment wasn't meant to pick on you, but whatever compiler/IDE you are using should have been spitting out ERRORS right and left. The fact that it compiled at all is surprising. The advise in the comment was sound. Always, always compile with warnings enabled and fix all warnings before you consider your code trustworthy.
That being said, you have a couple of areas where you are making things hard on yourself. You should pass the array, and a FILE* pointer (or filename) rather than hardcoding a filename in a function. That makes the function of very limited use. Your use of fgets, as you now know, was not correct. Further, after you pass your array, you need only read each word (assuming 1-per line) into the array while making sure your don't exceed the number of rows you have declared.
Here is a short example that will read from the filename given on the command line (or from stdin by default). It makes use of a ternary operator to either accept a filename as the first argument or set fp to stdin. Give it a try and let me know if you have questions:
#include <stdio.h>
#define MAXW 64 /* maximum number of lines to read */
#define MAXC 32 /* longest word in abridged Dict. is 28 char
"Antidisestablishmentarianism" */
size_t getwords (char (*words)[MAXC], FILE *fp);
int main (int argc, char **argv) {
char words [MAXW][MAXC] = {{0}}; /* array to hold words */
size_t nwords = 0; /* number of words read */
size_t i;
/* open argv[1] for reading (default: stdin) */
FILE *fp = argc > 1 ? fopen (argv[1], "r") : stdin;
if (!fp) { /* validate file open */
fprintf (stderr, "error: file open failed '%s'.\n", argv[1]);
return 1;
}
nwords = getwords (words, fp);
if (fp != stdin) fclose (fp); /* close file */
printf ("\n words read from '%s':\n\n",
argc > 1 ? argv[1] : "stdin");
for (i = 0; i < nwords; i++)
printf (" words[%2zu] : %s", i, words[i]);
return 0;
}
/* function to read words, 1 - per line, from 'fp' */
size_t getwords (char (*words)[MAXC], FILE *fp)
{
size_t idx = 0; /* index of words read */
/* read each line in file into words array
note: includes trailing newline character */
while (idx < MAXW && fgets (words[idx], MAXC, fp)) {
idx++;
/* note you should check if chars remain in line */
}
if (idx == MAXW) /* check word count against MAXW */
fprintf (stderr, "warning: MAXW words read.\n");
return idx;
}
Compile

I am trying to write another command button code which say:
If I input a "point" & (due to other criteria etc), the [row 79] of that column = "p", copy the value in [row 75] of that column. (Let's call this "Aboverow"
Then search backwards (to column C) along [row 79] for all cells/columns with "r" present in them.
For every column with "r" present in it, paste "Aboverow's" value into [row 80] of that column.
I have written the code for this but I keep getting "out of stack space error", I have tried to debug it, but am not sure where I am going wrong. The code is below. Any help will be very much appreciated.
Private Sub commandButton12_Click()
For Checkcol = 3 To 801
Dim Isnote As Variant
GoSub Isnote
Isnote:
If Cells(78, Checkcol) <> "o" Then
GoSub Isap
Else
End If
Dim Isap As Variant
Isap:
If Cells(80, Checkcol) = "p" Or Cells(80, Checkcol) = "pf" Or Cells(80, Checkcol) = "ps" Then
GoSub Myprocess
ElseIf Cells(80, Checkcol) = "r" Or Cells(80, Checkcol) = "rf" Or Cells(80, Checkcol) = "rs" Then
End If
Dim Myprocess As Variant
Dim Reg As Variant
Reg = "r"
Dim Rainj As Variant
If ActiveCell.Column = Range("J79") Then
Rainj = Range("J79") & ("C79")
End If
Dim Aboverow As Variant
Aboverow:
If ActiveCell.Column = Range("J79") Then
Range("J75").Select
Selection.Copy
End If
Dim Belowrow As Variant
Belowrow:
If Range("I79") = Reg Then
Range("I80").Select
End If
Myprocess:
GoSub Aboverow
For Each Reg In Rainj
GoSub Belowrow
Selection.Paste
Next Reg
Next
End Sub
A: As mentioned in the comments, this is why you should always avoid GoTo and GoSub like the plague. The immediate cause of your stack overflow is that you are calling GoSub and don't have any Return statements. That means in this section of code (the first infinite recursion I noticed, but probably not the only one)...
Aboverow:
If ActiveCell.Column = Range("J79") Then
Range("J75").Select
Selection.Copy
End If
Dim Belowrow As Variant
Belowrow:
If Range("I79") = Reg Then
Range("I80").Select
End If
Myprocess:
GoSub Aboverow
For Each Reg In Rainj
GoSub Belowrow
Selection.Paste
Next Reg
...your exceution jumps from the line with GoSub Belowrow, then it falls right back into the code below the Myprocess: label, which jumps above the Belowrow: label, which falls back into the code below the Belowrow: label, which...you get the idea.
While you could experiment with using Return to exit your "Subs", that style of coding died sometime in the 1970s for this exact reason. If you need a subroutine, you should make a sub-routine. Note that this is just an example - the flow control is convoluted enough that I have no idea what the code is supposed to do:
Sub AboveRow()
If ActiveCell.Column = Range("J79") Then
Range("J75").Select
Selection.Copy
End If
End Sub
Sub BelowRow()
If Range("I79") = Reg Then
Range("I80").Select
End If
End Sub
Sub Myprocess()
AboveRow
For Each Reg In Rainj
BelowRow
Selection.Paste
Next Reg
End Sub
Then the code quoted above would become just:
AboveRow
BelowRow
Myprocess
Note that there are many other issues around relying on Select and tracking the active cell, but that should at least get you closer to a point that you can start doing some more meaningful debugging on this.
A: In addition to what was already said...
*
*Don't declare line labels as local variables.
*Declare actual variables with actual data types. Using Variant when you mean Long can cost you some performance.
*Avoid working for nothing: if there's no code in an Else block, then there's no reason to have an Else If condition at all.
*Avoid working off the current Selection and ActiveCell. Use Range object references and work against that.
*Avoid implementing logic in click handlers - often you'll need more click handlers and you'll end up duplicating logic everywhere: that means you can have one bug, and twelve places to fix it.
So execution starts and assigns an undeclared Checkcol variable in a For loop that runs from 3 to 801.
For Checkcol = 3 To 801
That should probably be reworded to eliminate the hard-coded magic numbers:
Dim targetSheet As Worksheet
Set targetSheet = ActiveSheet 'ideally something more robust than that
Dim firstColumn As Long
firstColumn = FindFirstColumn(targetSheet) 'function that returns the first column with a heading in a specified worksheet
Dim lastColumn As Long
lastColumn = FindLastColumn(targetSheet) 'function that returns the last column with a heading in a specified worksheet
Dim currentColumn As Long
For currentColumn = firstColumn To LastColumn
Next instruction declares an Isnote variable, but that variable is really just a line label and shouldn't be declared at all.
Next we have a GoSub jump, that's redundant because it jumps to the line that would be executing next anyway - except here's the thing with GoSub: the VBA interpreter uses a mechanism called the call stack to track where it's at in the program. Because there is no Return statement, after that GoSub jump this is what the call stack might look like:
at label:Isnote
at sub:commandButton12_Click
Now, say Cells(78, Checkcol) <> "o". The call stack becomes this:
at label:Myprocess
at label:Isnote
at sub:commandButton12_Click
Now the MyProcess label starts by jumping to Aboverow, so the call stack grows again:
at label:Aboverow
at label:Myprocess
at label:Isnote
at sub:commandButton12_Click
AboveRow completes, but doesn't Return to the caller, so the last "frame" on the call stack is never "popped". Execution continues into Belowrow (without pushing the label to the stack) and then back into Myprocess (again without pushing it to the stack), and jumps back to Aboverow because that's what Myprocess does:
at label:Aboverow
at label:Aboverow
at label:Myprocess
at label:Isnote
at sub:commandButton12_Click
At that point execution is stuck: the stack will eventually fill up completely with at label:Aboverow stack frames, until it overflows its capacity and the runtime raises the run-time error you're seeing - "Out of stack space".
Let's rewind to here:
at label:Isnote
at sub:commandButton12_Click
If Cells(78, Checkcol) does contain an o, then we don't jump and everything is great, no?
Execution resumes into Isap (without pushing it to the call stack), and then conditionally jumps to Myprocess which we know is going to get us stuck. The ElseIf condition is otherwise evaluated... for nothing, because nothing happens anyway.
We assign Reg to a string value of "r", then Rainj to an interesting concatenated value of whatever string is found in Range("J79"), with the string literal value "C79", so if J79 contains Hello then that makes Rainj contain HelloC79 - I very much doubt that this is the intended behavior.
Anyway we eventually reach MyProcess, where we get stuck in that loop again.
This code is therefore unreacheable, there's no way it can ever get executed:
For Each Reg In Rainj
GoSub Belowrow
Selection.Paste
Next Reg
...which is a good thing, because it's trying to iterate what we now know is a string that ends with "C79". Even if Range("J79") contained something clever, e.g. "Sheet12!" so Rainj would be "Sheet12!C79", it would still be a string literal at that point, and that loop is trying to iterate it.
Looks like the intent was something like:
For Each Reg In Range(Rainj)
But what's Reg anyway? Reg contains the string literal value "r", and we're not doing anything with it... except in the BelowRow label, where we compare it against Range("I79"):
If Range("I79") = Reg Then
So when Range("I79").Value is "r" then we .Select cell I80... right? Except, that For Each loop is using Reg as an iterator, which in theory only has a meaningful value inside the body of the loop - and this is where my brain explodes and gives up trying to figure out what this is supposed to be doing: it looks like it wants to .Paste something in I80 when I79 has some hard-to-figure-out-without-a-debugger value... but then, the only thing that ever gets copied is J75 - so everything is constant here, except the value of J79.
Seems a very, very convoluted way to do:
ActiveSheet.Range("J75").Copy ActiveSheet.Range("I80")
...800 times over (well, not really, since execution can never reach the Next statement before overflowing the call stack).
A: Just thought I would post the working answer for my question, having fixed the code given to me:
Sub Macro1()
Dim targetSheet As Worksheet
Set targetSheet = ActiveSheet
For I = ActiveCell.Column - 1 To 1 Step -1
If Cells(78, I).Value2 = "r" Then
Cells(80, I).Value = Cells(75, ActiveCell.Column).Value
ElseIf Cells(78, I).Value2 = "p" Then
Cells(80, I).Value = Cells(75, ActiveCell.Column).Value
Exit For
End If
Next I
End Sub
Thanks again for the replies.

Yes, I know the code is a mess, but I'm doing this for a school/charity fundraiser, so any help is much appreciated.
A: You are looking for an element with id="namefull", but in your html, you only specify the name attribute: <input type="text" size="30" maxlength="30" name="namefull">
Try including id="namefull" in here:
<input type="text" id="namefull" name="namefull" size="30" maxlength="30">
You'll want to follow suit on each of your inputs to specify the id, since that's what you're looking for with document.getElementById().
A: getElementById() get's an element by it's ID. You need to set the id for that to work.
Change your markup to:
<table border="0" cellpadding="0" cellspacing="0">
<tr>
<td align="center" colspan="5" bgcolor="#CCFFFF"><b><font face = "Calibri">All Fields Required so we can contact you</b></td>
</tr>
<tr>
<td align="right" colspan="2" bgcolor="#CCFFFF"><b><font face = "Calibri">Name:</b></td>
<td colspan="3" bgcolor="#CCFFFF"><input type="text"
size="30" maxlength="30" name="namefull" id="namefull"></td>
</tr>
Notice I added id="namefull" to the input element.

Tho as much as I have tried, and normally I don't ask people for help because I like to figure things out on my own, I am stuck. I am writing in Python 3.2.2. So please can anyone see where I'm going wrong?
import urllib

import http.cookiejar
cookieJar = http.cookiejar.LWPCookieJar()
opener = urllib.request.build_opener(urllib.request.HTTPCookieProcessor(cookieJar))

Ringtone ringtone = RingtoneManager.getRingtone(mainActivity.getApplicationContext(), RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION));
ringtone.play();
This code is not in my MainActivity, or any other activity for that matter. It is in a thread that is started in the MainActivity. I passed a reference of MainActivity into the thread at start-up so I could do things like this, toasts, and such.
This works perfectly. Whenever a chat comes in, the notification sound is heard loud and clear.
My issue is this. In the logcat in AndroidStudio, I am getting this error:
E/MediaPlayer: Uri is content://settings/system/notification_sound
Like the title says, it appears to have no affect on my app, but I am worried that something is wrong, and that it could break my app in the future.
Do I need to worry about this? If so, how do I fix it?
Thanks!

Currently I take screenshots like this:
public void tearDown(Scenario scenario) {
if (scenario.isFailed()) {
final byte[] screenshot = ((TakesScreenshot) driver1).getScreenshotAs(OutputType.BYTES);
scenario.attach(screenshot, "image/png", null);
}
}
which always screen shots the first driver when either runs into a failure. how do i get the driver that has the error to screen shot?

Please tell me where am I wrong?
A: You regex matches 2 alternatives: 1 lower- or uppercase letter with [a-zA-Z], or a number with [0-9]{1,4}|[1-5][0-9]{4}|6[0-4][0-9]{3}|65[0-4][0-9]{2}|655[0-2][0-9]|6553[0-5].
It seems you are looking for
\b([a-zA-Z]+[0-9]*|(?:[0-9]{1,4}|[1-5][0-9]{4}|6[0-4][0-9]{3}|65[0-4][0-9]{2}|655[0-2][0-9]|6553[0-5]))\b
See demo
Or, if the strings are tested against the regex individually, use ^/$ anchors:
^([a-zA-Z]+[0-9]*|(?:[0-9]{1,4}|[1-5][0-9]{4}|6[0-4][0-9]{3}|65[0-4][0-9]{2}|655[0-2][0-9]|6553[0-5]))$

The array is @@players_list, which has an unknown number of players.
I tried:
@@players_list = [player1, player2, player3]
tied = @@Players_.list.find_all {|p| p.win_value.to_s.count(p.win_value.to_s) > 1}
This does not return an error, but also does not identify the duplicate score values
tied = @@players_list.select {|p| array{|p| p.score_value}.count(p.score_value) > 1}.uniq
This returns:
syntax error, unexpected '}', expecting keyword_end
..._value}.count(p.win_value) > 1}.uniq
A: Thanks to Sergio Tulentsev for getting me 90% there. Here's what I came up with that seems to work.
group_by_win_value = @@players_list.group_by(&:win_value)
group_by_win_value.each do |key, value|
@tied_players = []
if value.count > 1
puts "the following players are tied"
value.each do |player|
puts player.name``
@tied_players << player
end
end

For my local testing,
First way: "php artisan serve" on the project root directory
---> localhost:8000/item
Second way: "php -S localhost:8080" in the public folder
---> localhost:8080/item
However, when upload my laravel project to server via FileZilla.
It returns HTTP Error 500 when "xxx.com/item"
but I can see "xxx.com/index.html" when I put index.html on the same directory
How to deploy the project? need to install or config something? SSH?
Thanks
A: I have already answered a question like this here
Archive/Compress/Zip your project and upload it to public_html and Extract it
Create a Database in mysql databases ( in cPanel )
Import .sql file from local phpmyadmin to online hosting
Now go to public_html and edit .env file, change the following
DB_DATABASE=DatabaseName
DB_USERNAME=DatabaseUsername
DB_PASSWORD=DatabasePassword
and now just open yourwebsite.com and your app will be there !
A: you have to link your domain path to /public in your project or you could use .htaccess file on root folder to redirect it in /public folder. Because public folder contains the index.php file.

The problem I have with these files is that when I try to open them with R, they generate a blank dataframe. This is fixed by opening the xls file and saving it without making any other changes.
I would like to know if anyone else has had this problem? The solution of opening and saving each file is not useful for me, since the number of files is large.
I have used the read_xls function from the readxl package.
This is my sessionInfo()

I have just one user that gets periodic errors saying "The handle is invalid". If she tries printing a second time, it works just fine.
I've looked over her machine and it looks like it has all the same software as everyone else, and of course it never happens when I'm around.
The code I'm using is: frmPrint.LogTag1.PrintToPrinter(1, True, 1, 0)
I'm not sure if there is any other information that I can get from an end user machine to help me figure out where the problem is. ErrorToString() only returns that one line.
A: It is a low-level Windows error. Could be a bug in Crystal Reports, could be a bug in the printer driver, could be environmental with some kind of misbehaving system add-on. You'll never find out which it is if you don't have the source code for these large chunks of code so you can debug it. You don't and you can get it.
It is not a bug in your code, ask the IT staff to get that user another machine. If that doesn't help then you'll have to bounce this to Crystal Decisions (or whatever they are called these days). This is otherwise a standard IT matter.

Or get all JPopupMenu components that then could be filtered by visibility, validity etc.
I need this for writing tests. Stuck on JPopupMenu-s is not part of parent-child (container-component) relations.
Thanks.
resolved: JPopupMenu is Window and it is listed in java.awt.Window.getWindows()
A: For all unit tests with swing we use the Fest framework. There is a popup menu fixture that will allow you to test stuff on the popup menu.
https://github.com/alexruiz/fest-swing-1.x
Using the framework I am sure you can search for all popup menus shown by searching with the name you set for the JPopupMenu.
EDIT:
The framework maintenance changed hands a few years ago. Please check before using it.
A: As comments show this is not trivial as effected by light and heavyweight concerns... For example in some cases JPopupMenu can be nested inside a JRootPane. However this in an alternative public API that be used - javax.swing.MenuSelectionManager which can be used to get list of JPopupMenus. I found this inside javax.swing.plaf.basic.BasicPopupMenuUI.getPopups()
static List<JPopupMenu> getPopups() {
MenuSelectionManager msm = MenuSelectionManager.defaultManager();
MenuElement[] p = msm.getSelectedPath();
List<JPopupMenu> list = new ArrayList<JPopupMenu>(p.length);
for (MenuElement element : p) {
if (element instanceof JPopupMenu) {
list.add((JPopupMenu) element);
}
}
return list;
}
Original solution using Window.getWindows()
private boolean isPopupMenuOpen() {
for (Window each : Window.getWindows()) {
if (findPopup(each) != null) {
return true;
}
}
return false;
}
private JPopupMenu findPopup(Component root) {
if (root instanceof JPopupMenu) {
return (JPopupMenu) root;
}
if (root instanceof JWindow) {
return findPopup(((JWindow)root).getContentPane());
}
if (root instanceof JRootPane) {
return findPopup(((JRootPane)root).getLayeredPane());
}
if (root instanceof Container) {
for (Component each : ((Container) root).getComponents()) {
return findPopup(each);
}
}
return null;
}
A: JPopupMenu is Window and it is listed in java.awt.Window.getWindows()

So far, I have created a new profile:
General section - put 'dir_1' in the badge field and selected 'Home Directory' as the Working Directory Option.
Advanced section - I am having trouble figuring out the formatting - I've tried iterations of ...
"/Users/erica.dohring/dir_1"
"~/dir_1"
without the quotes, etc
Could someone provide guidance as to how to do this?
A: I realize this is a reasonably old question, but google led me here for a similar question (how to change background color based on directory).
Was able to make this work by creating a couple of profiles, then using the equivalent of the pwd in the Preferences>Advanced>Automatic Profile Switching list, i.e. /Users/ted_foss/workspace/ or, for all sub-dirs under that, /Users/ted_foss/workspace/* .

"%E3%83%9C%E3%83%89%E3%82%AB%E3%81%95%E3%82%93"
It actually means this
ボドカさん
This string seems to be encoded in UTF-8 because when I write this in python
encoded_str = b'\xe3\x83\x9c\xe3\x83\x89\xe3\x82\xab\xe3\x81\x95\xe3\x82\x93'
print(encoded_str)
print(encoded_str.decode('utf-8'))
Here is the output I get
b'\xe3\x83\x9c\xe3\x83\x89\xe3\x82\xab\xe3\x81\x95\xe3\x82\x93'
ボドカさん
But now I would like a script that will allow me to decode any string in the initial format and here is my code.
import re
import os
mystr = "%E3%83%9C%E3%83%89%E3%82%AB%E3%81%95%E3%82%93"
mystr = mystr.lower()
mystr = re.sub('%', r'\\x', mystr)
encoded_str = bytes(mystr, "utf-8")
print(mystr)
print(encoded_str)
print(encoded_str.decode('utf-8'))
Output:
\xe3\x83\x9c\xe3\x83\x89\xe3\x82\xab\xe3\x81\x95\xe3\x82\x93
b'\\xe3\\x83\\x9c\\xe3\\x83\\x89\\xe3\\x82\\xab\\xe3\\x81\\x95\\xe3\\x82\\x93'
\xe3\x83\x9c\xe3\x83\x89\xe3\x82\xab\xe3\x81\x95\xe3\x82\x93
I tried so many possibilities but I couldn't find the right way to encode proprely my string like the b'STRING' thing would do. I always get extra \ characters from the encoding process that then spoil the decoding process too.
I tried all the encoding methods existing in python for the bytes() function.
I need help please. Thank you.
Stack overflow banned me for that question lol
A: mystr = "%E3%83%9C%E3%83%89%E3%82%AB%E3%81%95%E3%82%93"
encoded_str = bytes.fromhex(mystr.replace('%', ''))
print(encoded_str.decode('utf-8'))

But when I try to build the suggester, I get an error
Caused by: java.lang.IllegalArgumentException: Document contains at least one immense term in field="exacttext" (whose UTF8 encoding is longer than the max length 32766), all of which were skipped. Please correct the analyzer to not produce such terms. The prefix of the first immense term is...
There is no field named exacttext in my entire setup, though.
When I use the FreeTextLookupFactory, this doesn't happen, but then I can't use the contextField, of course.
I tried adding
<filter class="solr.LengthFilterFactory" min="2" max="32700"/>
as well as
<filter class="solr.TruncateTokenFilterFactory" prefixLength="100"/>
to the managed schema, but this didn't work, either.
Here's the searchComponent I tried using:
<searchComponent name="suggest" class="solr.SuggestComponent">
<lst name="suggester">
<str name="name">mySuggester</str>
<str name="lookupImpl">AnalyzingInfixLookupFactory</str>
<str name="dictionaryImpl">DocumentDictionaryFactory</str>
<str name="field">suggestText</str>
<str name="highlight">false</str>
<str name="storeDir">mySuggester</str>

<str name="buildOnCommit">false</str>
<str name="buildOnStartup">false</str>
<str name="contextField">context_field</str>
</lst>
</searchComponent>
And this is the config for the suggester in the managed-schema:
<fieldType name="suggestField" class="solr.TextField" positionIncrementGap="100">
<analyzer>
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.WordDelimiterFilterFactory" generateWordParts="1" catenateWords="1" generateNumberParts="0" splitOnCaseChange="0"/>

ERROR [alembic.util.messaging] Online migration expected to match one row when updating '3aae6532b560' to 'a1d8dae7cc' in 'alembic_version'; 2 found
FAILED: Online migration expected to match one row when updating '3aae6532b560'
to 'a1d8dae7cc' in 'alembic_version'; 2 found
alembic current
gives two similar versions of alembic like:
3aae6532b560
3aae6532b560
How do I delete one of the similar versions of alembic, i.e a copied version?
alembic history doesn't show any messed up output.
Thanks!
A: Alembic version is stored within your database in alembic_version table. I see that you have two self same rows inside the table.
You can do something like this:
DELETE FROM alembic_version WHERE version_num='3aae6532b560';
INSERT INTO alembic_version VALUES ('3aae6532b560');
Above query could be done in one query by limiting number of deleted rows, but limiting within DELETE query is different between different databases engines.

The thing is that I don't know how to configure connectDistributed.out file in Kafka Connect. Following is the sample output of the file:

A: The connectDistributed.out file only exists if you use daemon mode, e.g.
connect-distributed -daemon connect-distributed.properties
Reason: From kafka-run-class script, CONSOLE_OUTPUT_FILE is set to connectDistributed.out
# Launch mode
if [ "x$DAEMON_MODE" = "xtrue" ]; then
nohup $JAVA $KAFKA_HEAP_OPTS $KAFKA_JVM_PERFORMANCE_OPTS $KAFKA_GC_LOG_OPTS $KAFKA_JMX_OPTS $KAFKA_LOG4J_OPTS -cp $CLASSPATH $KAFKA_OPTS "$@" > "$CONSOLE_OUTPUT_FILE" 2>&1 < /dev/null &
else...
Option 1: Load a custom log4j property file
You can update the KAFKA_LOG4J_OPTS environment variable to point at any log4j property file that you want to before starting connect (see example below)
$ export KAFKA_LOG4J_OPTS="-Dlog4j.configuration=file://path/to/connect-log4j-new.properties"
$ connect-distributed connect-distributed.properties
Notice: Not using -daemon here
If you no longer have ConsoleAppender in the log4j properties, this will output next to nothing, and just hang, so would be good to nohup it.
The default log4j config is named connect-log4j.properties, and in Confluent Platform, this is at etc/kafka/ folder. This is what it looks like by default
log4j.rootLogger=INFO, stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
In order to set a max log file size, you'll need change the root logger to go to a FileAppender rather than ConsoleAppender, but I prefer using a DailyRollingFileAppender.
Here is an example
log4j.rootLogger=INFO, stdout, FILE
log4j.appender.FILE=org.apache.log4j.DailyRollingFileAppender
log4j.appender.FILE.DatePattern='.'yyyy-MM-dd
log4j.appender.FILE.File=/var/log/kafka-connect/connect.log
log4j.appender.FILE.layout=org.apache.log4j.PatternLayout
log4j.appender.FILE.layout.ConversionPattern=[%d] %p %m (%c)%n
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=[%d] %p %m (%c:%L)%n
log4j.logger.org.apache.zookeeper=ERROR
log4j.logger.org.I0Itec.zkclient=ERROR
log4j.logger.org.reflections=ERROR
A: I don't have enough reputation to comment (but I can answer...) so I just want to point out in response to cricket's answer I would NOT use DailyRollingFileAppender. In the docs themselves it says it is unadvised due to synchronization and data loss issues. Instead I would use RollingFileAppender in conjunction with TimeBasedRollingPolicy. I noticed this after some odd behavior with DailyRollingFileAppender in Kafka Connect. You will need to include the log4j "extras" jar in the classpath to make this work.

A: You can't add a transition to display:none; rules. You must change all of them to opacity, like follows. Take into account that here's only the code that has been changed:
.work_slider:hover .slider_detail h3,
.work_slider:hover .slider_detail p
{
opacity: 1;
}
.work_slider:hover .slider_overlay
{
opacity: .85;
}
.slider_overlay
{
transition: all .3s ease;
opacity: 0;
}
.slider_detail h3
{
transition: all .3s ease;
opacity: 0;
}
.slider_detail p
{
transition: all .3s ease;
opacity: 0;
}

The problem I encounter it returns a string which is an array of objects. If I use JSON.parse() is going to give me an error such as unexpected token ‘ in JSON at position 2 in JSON.parse
[{1:a, name:name, etc...}, {1:a, name:name, etc...}, {1:a, name:name, etc...}, {1:a, name:name, etc...}, {1:a, name:name, etc...},]
I got this string from:
twitter_search.py
...
for tweet in tweets:
# data.append({"tweet": tweet.full_text})
data.append({"time": str(tweet.created_at), "user" : str(tweet.user.screen_name), "tweet": str(tweet.full_text)})
...
in app.py
@app.route('/')
def index():
ip = supp.get_data('https://freegeoip.app/json/')
iptojson = json.loads(ip.content)
sctojson = ip.sc
data = twitter_search.twsejs()
s1 = json.dumps(data)
d2 = json.loads(s1)
return render_template('index.html',data=d2, iptojson = iptojson, sctojson = sctojson)
But it is a string and I need to use it as a JSON what can I do? I tried everything JSON.dumps dump parse can't figure it out
This is an example of a get req

A: Making a request to an API comports to receive all sorts of responses. In order to have a well-formatted JSON, all I had to do is use a regex and avoid things such as double quotes, special characters, and brake lines. This made me have a cleaner JSON.

Test Class-
public static void main(String[] args) {
GeographyList g = new GeographyList();
g.addCountry ("Scotland");
g.addCountry ("Wales");
g.addCountry ("Ireland");
g.addCountry ("Italy");
System.out.println(g.toString());
ArrayList setup
public class GeographyList {
private ArrayList<String> countries;
public GeographyList(){
countries = new ArrayList<>();
}
public ArrayList<String> getCountries() {
return countries;
}
public String getCountry(int index){
return countries.get(index);
}
public void addCountry(String aCountry){
countries.add(aCountry);
System.out.println(aCountry + " added.");
}
A: The reason it prints geographylist.GeographyList@15db9742 is because you are not printing an ArrayList. You are printing a GeographyList. A GeographyList may contain an ArrayList, but that's incidental.
The default implementation of toString, inherited from the Object class, is to print the package name geographylist, the class name GeographyList and the hash code 15db9742.
If you want to override this behaviour, you will need to override the behaviour of toString, just as the ArrayList class will have done itself.
That might look something like this:
public class GeographyList {
//...
@Override
public String toString()
{
return countries.toString();
}
}
Alternatively, since you already have the ability to get the ArrayList from your class, you could call
System.out.println(g.getCountries().toString());
instead of
System.out.println(g.toString());

Here is ASP.NET Code
<form id="form1" runat="server">
<div id="dvLeft"></div>
<div id="dvRight"></div>
<div id="dvMiddle"></div>
<div id="dvBottom">
<asp:DropDownList ID="ddlTheme" runat="server" AutoPostBack="True">
<asp:ListItem >FirstTheme</asp:ListItem>
<asp:ListItem>SecondTheme</asp:ListItem>
<asp:ListItem>ThirdTheme</asp:ListItem>
</asp:DropDownList>
</div>
</form>
And Here is C# Code:
protected override void OnPreInit(EventArgs e)
{
if (Request["ddlTheme"] != null)
{
string theme = Request["ddlTheme"].ToString();
Page.Theme = theme;
}
base.OnPreInit(e);
}
A: I'd suggest you set selected theme value in the PreRender event handler instead of PreInit because of the way ASPX page life cycle works.
Below is revised version from your original code
<form id="form1" runat="server">
<div id="dvLeft"></div>
<div id="dvRight"></div>
<div id="dvMiddle"></div>
<div id="dvBottom">
<asp:DropDownList ID="ddlTheme" runat="server" AutoPostBack="True" OnSelectedIndexChanged="ddlTheme_SelectedIndexChanged">
<asp:ListItem Value="FirstTheme">FirstTheme</asp:ListItem>
<asp:ListItem Value="SecondTheme">SecondTheme</asp:ListItem>
<asp:ListItem Value="ThirdTheme">ThirdTheme</asp:ListItem>
</asp:DropDownList>
</div>
</form>
protected void ddlTheme_SelectedIndexChanged(object sender, EventArgs e)
{
// save value into a session variable
Session["SelectedTheme"] = ddlTheme.SelectedValue;
}
protected void PreRender()
{
// works when page reloads
if (Session["SelectedTheme"] != null){
Page.Theme = Session["SelectedTheme"].ToString();
}
// following line works on postback only
//Page.Theme = ddlTheme.SelectedValue;
}
Update
My original suggestion would only work on postback because when the page reloads, a new page life cycle begins and the selected value from the drop down list would be lost.
However, there's a way to persist the change, which is to use session. To do this, you will attach a new event handler OnSelectedIndexChanged where you can save the selected value into a session variable. Then read this value from session after page reloads. See the added code snippet above.

I'm trying to query for a certain element type, say a "city". However, this element is listed under various other types of elements, such as "country" and "region". What is a good way to query for all "city" element types regardless of their parent element?
thank you
A: *
*You could write //city to find all city elements anywhere in the document.
*You could also use /descendant-or-self::city, which is different from the first statement in that it will give you any city elements from the context (starting point where you are executing the statement from).
*If you would like to limit the city elements to all with country as parent, you would write: //country/city.
*If you would like to get city elements at a specific depth in a tree, write something like: /*/*/city.

so, that's my code:
function getTableValues($table_name)
{
// $link = connect_db();
$front_end_query = "SELECT * FROM `".$table_name."` WHERE `type` = 'front_end'";
$front_end_query_result = mysql_query($front_end_query);
$cur_row = 0;
/*while ($line = mysql_fetch_assoc($queryresult))
{
$values = $line;
$cur_row++;
}*/
$front_end = mysql_fetch_assoc($front_end_query_result);
$i=0;
while ($line = mysql_fetch_assoc($front_end_query_result)){
#if ($line['type'] === 'front_end'){
# $line[$line['type']][$line['name']] = $line['value'];
# $line[$line['type']][$line['name']]['desc'] = $line['description'];
# $line[$line['type']][$line['name']]['visible_name'] = $line['visible_name'];
# $line[$line['type']][$line['name']]['write_roles'] = $line['write_roles'];
# $line[$line['type']][$line['name']]['read_roles'] = $line['read_roles'];
#}
$values['front_end'][$line['name']] = $line;
$i++;
}
return $values;
}
And my MySQL table:
id type write_roles read_roles name value description visible_name
1 front_end 0 any title sometitle exampletitle Title
2 front_end 0 any description somedesc example Description
And that's what I want to get:
$config[(someType)][(SomeName)] = (value of line)
$config[(someType)][(SomeName)][(SomeOption)] = (value of option)
E.g.: $config['front_end']['title']['description'] that returns exampletitle
How I can do that?
UPD0: so I tried to echo my array with foreach, and it's returned just one row from my DB.
What I doing wrong?
A: $values = array(); //base array
while ($line = mysql_fetch_assoc($front_end_query_result)){ //fetch the rows
//in the base array create a new array under 'name'
$values[$line['name']] = array();
//for each item in the result set, add it to the new array
foreach ($line as $key => $value) {
$values[$line['name']][$key] = $value;
}
}

My first attempt:
template< typename T > class invert;
template< typename port >
class invert< port > : public port {
public:
static int n_pins(){ return port::n_pins(); }
static void set( unsigned int x ){ port_out::set( x ^ 0xFFFF ); }
};
template< typename pin >
class invert< pin > : public pin {
public:
static void set( bool x ){ pin::set( ! x ); }
};
I hoped the first specialization would be selected when a T::n_pins() was available, but the compiler complains my specializations do not specialize any template argument.
Is there another way I can specialize on a property of the typename argument?
A: Why your code didn't work
The template parameters port and pin are just formal parameters. E.g. for regular functions, would you expect that
void foo(int x) { /* bla */ }
and
void foo(int y) { /* meh */ }
to be different from each other? In fact, you can simply declare such functions in a header by their signature void foo(int) only. To overload functions you need to provide different arguments.
With template parameters, it works exactly the same
template<typename port> class invert { /* bla */ };
and
template<typename pin> class invert { /* bla */ };
have the same template signature and can in fact be declared as template<typename> class invert; inside a header.
Here, the analogy breaks down because class templates don't overload, but have to be specialized. This means that your two versions of invert need to be "different enough" in their parameter structure, regardless of what you write in the class implementation itself.
How to fix it
To get what you want, you actually need to specialize at least one of the tempaltes. The typical way to do that has been explained on here before, and is to define a traits class and use SFINAE to select at compile-time:
template <typename T>
class has_n_pins
{
typedef char one;
typedef long two;
template <typename C> static one test( typeof(&C::n_pins) ) ;
template <typename C> static two test(...);
public:
enum { value = sizeof(test<T>(0)) == sizeof(char) };
};
template<typename T, bool = has_n_pins<T>::value >
class invert: public T
{
// your current port implementation
};
// specialization for types T that don't have a n_pins() member function
template<typename T>
class invert<T, false>: public T
{
// your current pin implementation
};
Now there are two specializations: invert<T, true> (all T that have n_pins()) and invert<T, false> (all T that don't). The compiler will now be able to select the appropriate one depending on the template argument you actually provided.

I want to echo my url from my index.php, it didnt work for me so i included the php code. if it help i have include .htaccess file.thanks
Notice: Undefined index: url in /var/www/mvc/index.php on line 3
<?php
$url = isset($_GET['url']);
echo $url;
?>
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-l
RewriteRule ^(.*)$ index.php?url=$1 [PT,L]
</IfModule>
A: This doesn't relate to your htaccess file, it simply states that the get param has no index with that name.
Try dumping out your $_GET to see its contents.
A: isset returns a boolean.
So you need to wrap it in an if statement in case.
$url = (isset($_GET['url'])) ? $_GET['url'] : 'index';
echo $url;
Doing so will suppress the notice.

What I need is a way to remove the old data and replace it with new data. I have read that it is easy to update a div tag with some javascript. However, I have only seen examples with a certain amount of time has passed or when a button is clicked. Neither of these are options for what I am doing. I do not know javascript.
I see this link, but without any context, it means nothing to me. How to use python variable in javascript getElementById()?
How can I accomplish this?
Thanks in advance!
A: So I found this workaround. I do not really like it.
I create a text variable with javascript code in it and the number that needs to update. Then I print that line. As the number updates, I reprint that text variable.
#! /usr/bin/env python
import cgi
import time
import sys
import json
print "Content-type: text/html\n\n"
#<meta http-equiv='refresh' content='5'>
print """
<head></head>
<body>
<p id='p'> </p>
"""
num = 19
#js = "<script>document.getElementById('p').innerHTML = " + str(num) + "; </script>"
js = "<script>document.getElementById('p').innerHTML = " + json.dumps(num) + "; </script>"
print js
sys.stdout.flush()
while num < 22:
num += 1
time.sleep(1)
#js = "<script>document.getElementById('p').innerHTML = " + str(num) + "; </script>"
js = "<script>document.getElementById('p').innerHTML = " + json.dumps(num) + "; </script>"
print js
sys.stdout.flush()
print"""
</body>
</html>

How can I extract these event handlers with my own so I can easily mock them?
A: You'll need to wrap the class in your own class supporting an interface. For example if your service usage looks like this:
var service = new SomeService();
service.SomeEvent =+ (o, e) => DoSomething(e);
service.DoStuff();
You'll create an interface:
public interface ISomeService
{
event EventHandler SomeEvent;
void DoStuff();
}
And your implementing class:
public class SomeServiceWrapper : ISomeService
{
private readonly SomeService _containedService;
public event EventHandler SomeEvent;
public SomeServiceWrapper()
{
_containedService = new SomeService();
_containedService.SomeEvent += (o, e) => RaiseSomeEvent(e);
}
public void DoStuff()
{
_containedService.DoStuff();
}
private void RaiseSomeEvent(EventArgs e)
{
EventHandler evt = SomeEvent;
if (evt != null)
{
evt(this, e);
}
}
}
Then you can create a dummy ISomeService via mocking or your own dummy class, and you use the ISomeService instance SomeServiceWrapper in production.
Hope that helps.

DATA
DATA_ID | SAMPLE_ID | ASSAY_ID | SIGNAL
101 | 201 | 301 | 2.87964
102 | 201 | 302 | 7.64623
103 | 202 | 301 | 1.98473
...
And SAMPLES:
SAMPLE_ID | SAMPLE_NAME | CATEGORY
201 | SAMP0001 | CAT A
202 | SAMP0002 | CAT B
203 | SAMP0003 | CAT A
...
There are about 20,000 rows in SAMPLES. For each sample, there are about 40,000 rows in DATA. Each ASSAY_ID occurs exactly once per sample in DATA. I need to take a subset of the samples in SAMPLE and calculate a standard/z-score value for each signal value in DATA, grouping by ASSAY_ID. I am trying to create a stored procedure that will be called repeatedly, which will accept a single ASSAY_ID value and return SAMPLE_ID and ZSCORE pairs for all of the samples in the predefined sample subset.
Given a set of sample signal values (X = [3.21, 4.56, 1.12, ..]) for a given assay, the standard/z-score in this case is calculated as
(X[i] - median(X))/(K * MAD)
Where K is a scale factor equal to 1.4826 and MAD is the median adjusted deviation, equal to:
median(|X[i]-median(X)|)
Got that? Good :) Now, what is the most efficient way to perform this calculation using a SQL query? Execution time is key, given that there are close to a billion rows in DATA and a z-score needs to be calculated for almost every SIGNAL value.
Here is the best query I have been able to come up with so far:
WITH BASE AS (
SELECT
S.SAMPLE_ID,
D.SIGNAL
FROM
DATA D
JOIN SAMPLES S
ON D.SAMPLE_ID = S.SAMPLE_ID
WHERE
S.CATEGORY IN ('CAT A', 'CAT B')
AND D.ASSAY_ID = 12345
AND S.SAMPLE_NAME NOT IN ('SAMP0003', 'SAMP0005', 'SAMP0008')
)
SELECT
A.SAMPLE_ID,
(A.SIGNAL-B.MED)/(1.4826*C.MAD) AS ZSCORE
FROM
BASE A,
(
SELECT MEDIAN(X.SIGNAL) AS MED
FROM BASE X
) B,
(
SELECT MEDIAN(ABS(Y.SIGNAL-YY.MED)) AS MAD
FROM BASE Y,
(SELECT MEDIAN(SIGNAL) AS MED FROM BASE) YY
) C
Is there a more efficient way to perform this query?
Bonus Question: Can I write a single SQL query that would perform this calculation for EVERY ASSAY_ID in a single execution?
A: Can you have a look at:
SELECT ASSAY_ID, SAMPLE_ID,
(SIGNAL - MED)/(1.4826F * MAD) AS ZSCORE
FROM (
SELECT ASSAY_ID, SAMPLE_ID, SIGNAL, MED,
MEDIAN(ABS(SIGNAL - MED)) OVER (PARTITION BY ASSAY_ID) AS MAD
FROM (
SELECT ASSAY_ID, SAMPLE_ID, SIGNAL,
MEDIAN(SIGNAL) OVER (PARTITION BY ASSAY_ID) AS MED
FROM DATA D
JOIN SAMPLES S USING (SAMPLE_ID)
WHERE S.CATEGORY IN ('CAT A', 'CAT B')
AND S.SAMPLE_NAME NOT IN ('SAMP0003', 'SAMP0005', 'SAMP0008')
AND D.ASSAY_ID = 301
)
);
Is it correct? Is it faster? If it is, just remove the AND D.ASSAY_ID = 301 clause for the bonus question :-)
On the physical side, I would look into the data type for signal (BINARY_FLOAT or BINARY_DOUBLE are supposedly faster than NUMBER). And, if this is an option, I'd try to physically collocate the assays with partitions.
