How can I get a value from the select box in JQuery : I want to get the value of the selected option from the selected box by using JQuery but it ain't working.
I have tried a million ways to do it. Trying to get its text instead, tried to get the value from multiple ways. To know what is coming in my jquery variable.
```
<!-- HTML Code -->
<select class="form-control" id="cateogry" name="category">
<option value="0" disabled selected>Choose Project Category</option>
<option value="active">Active Project</option>
<option value="drafted">Drafted Project</option>
</select>
<!-- JQuery Script -->
<script>
$(document).ready(function () {
//First thing i tried
var category = $('#category').val();
alert(Category);
//Second thing i tried
var category = $('#category').filter(":selected").val();
alert(Category);
//Third thing i tried
var category = $('#category').find(":selected").text();
alert(Category);
//Fourth thing i tried
var category = $('#category').find(":selected").val();
alert(Category);
//Fourth thing i tried
var category = document.getElementById('category').value;
alert(Category);
//Now directly taking the value of selected option by id
alert($("#category :selected").attr('value'));
//These are the code snippets I tried at different times so don't
think that I did this all a time which can obviously throw some
exception.
});
</script>
```
All the options I have given above and tried all of them one by one and put an alert to see what is it getting and the alert said undefined. What can I do? | 0debug |

How to upgrade minikube? : <p>I had installed <em>minikube</em> a few months ago and wanted to upgrade as newer versions are available.</p>

<p>I tried to then uninstall <em>minikube</em> and hit another brickwall again. I don't see a command to uninstall <em>minikube</em>. The information that came closest to this was not very helpful - <a href="https://github.com/kubernetes/minikube/issues/1043" rel="noreferrer">https://github.com/kubernetes/minikube/issues/1043</a></p>
<p>I guess we need ways to upgrade these (at least once every 6 months or so).</p>

Why is SVG scrolling performance so much worse than PNG? : <p>A site I'm working on displays a large number (>50) of complex SVG images in a scrolling dialog window. When viewing the site in Chrome, the scrolling performance of the dialog window is very poor - it is noticeably laggy and slow. However, if I replace the SVG images with PNG images, the scrolling is perfectly smooth and responsive.</p>
<p>Here's a demonstration of the difference: <a href="https://jsfiddle.net/NathanFriend/42knwc1s/" rel="noreferrer">https://jsfiddle.net/NathanFriend/42knwc1s/</a></p>
<p>Why is the SVG scrolling performance so much worse than the PNG scrolling performance? After the browser renders an SVG image, I would assume it doesn't need to rerender the image until the image is manipulated in some way (like resizing). Does scrolling an element that contains SVG images cause the images to be rerendered for every frame of the scroll animation?</p>

<p>After that I used the command <strong>npm run build</strong>, I followed the instructions, I installed the <strong>push-state</strong> and I tested using localhost. Everything worked fine. </p>
<p>But I uploaded the build files to my EBS and it complains that the app does not have the <strong>package.json</strong> file and the app does not work.</p>
<p>What do I have to do to put in package.json to deploy my react app using Elastic Beanstalk? How to deploy the build files generated by <strong>npm run build</strong> in EBS?</p>

Android - Button with if condition :
I am newbie in Android, and i am trying to make a one button open 2 activities but is not working for me.
for ex:
on `Mainacitivity`, there is `btn_mathematics` and `btn_physics` open the same activity (`Main2acitivity`) and find `btn_semester1` and `btn_semester2`, each button will open 2 other activities for the semester modules.
If the user on Mainacitivity clicked on:
`btn_mathematics` ---> `btn_semester1`---> will have `ModulesMAT`
and if clicked on the btn_semester1 same button:
`btn_physics` ---> `btn_semester1` ---> will have `ModulesPHY` .
**MainActivity XML:**
<Button
android:id="@+id/btn_mathematics"
android:onClick="btn_mathematics"
android:text="@string/btn_mathematics/>
<Button
android:id="@+id/btn_physics"
android:onClick="btn_physics"
android:text="@string/btn_physics"/>
**Main2Activity XML:**
<Button
android:id="@+id/btn_semester1"
android:onClick="btn_semester1"
android:text="@string/btn_semester1"/>
<Button
android:id="@+id/btn_semester2"
android:onClick="btn_s2"
android:text="@string/btn_semester2"/>
I guess that no need to add xml for ModulesMAT and ModulesPHY, its pretty similar to the the others.
and now the java code:
**MainActivity.java:**
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void btn_mathematics (View v) {
Intent intent = new Intent(MainActivity.this, Main2Activity.class);
startActivity(intent);
}
`public void btn_physics (View v) {
Intent intent = new Intent(MainActivity.this, Main2Activity.class);
startActivity(intent);
}
}
**Main2Activity.java:**
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main2);
}
public void btn_semester1 (View v)
{
Intent i = getIntent();
String id = i.getStringExtra("id");
if(id == "btn_mathematics")
{
i = new Intent(this, ModulesMAT.class);
startActivity(i);
}
else if (id == "btn_physics")
{
i = new Intent(this, ModulesPHY.class);
startActivity(i);
}
}
public void btn_semester2 (View v)
{
Intent i = getIntent();
String id = i.getStringExtra("id");
if(id == "btn_mathematics")
{
i = new Intent(this, ModulesMAT2.class);
startActivity(i);
}
else if (id == "btn_physics")
{
i = new Intent(this, ModulesPHY2.class);
startActivity(i);
}

Is creating Equilateral responsinve triangle with backgroung image in css even possibe? : And it also should work in IE11.
I've tried:
- Usuall triangle-crating techinces using border - **Failed**, no background image.
- Clip-path - **Failed** no ie support (damn)
- Triangles with skewing and transfroming have to war of having proper percedt-based lenghts. After ~3 hours of trying to fugure it out - **Failed**
My last desperate effort will probbaly be creating an SVG mask with triangle cutted in it and placing it on top of the <div> with desiered image. But it feels so damn hacky.
And no, it is not my wish to complicate my life so much, its a test task ive got, and i've allready burned away whole day of time, and shitton amount of nerves. Please help! | 0debug |

Is there a naming convention for C language implementation only (private) constants? : <p>Let's say that I am writing a library named <code>my</code>, which has a module <code>myString</code>.</p>
<p>Publicly exposed functions and constants for <code>myString</code> are declared in <code>myString.h</code> with the following convention:</p>
<pre><code>typedef struct myString myString;
extern const size_t MY_STRING_MAX_LEN;
myString *my_string_new();
</code></pre>
<p>Private implementation only functions and struct members are declared in <code>myString.c</code> with the following convention:</p>
<pre><code>_grow_buffer(myString *this);
char *_buffer;
</code></pre>
<p>My question: Is there a similar convention for private, implementation only constants?</p>
<p>For example, <code>_CHUNK_SIZE</code> is what I initially wanted to go with. Then I read that the C language specification says not to use an underscore followed by an uppercase letter at the start of a name, as such names may be used in future versions of the language.</p>
<p>I like using the starting underscore convention, as it removes a lot of verbosity. I could use <code>MY_STRING_CHUNK_SIZE</code> or some variation, but that's not as pretty IMO.</p>

What is the pythonic way for 'do_this() if condition else do_that() '? : There is exists a pythonic way for doing somethings like that?
>> list.append(elem) if condition else pass
>> list.append(elem) if condition else other_list.append(elem)
I have needed sometimes something like that and I don't know the best way for accomplish it.
Thanks. | 0debug |
Do you need to allocate memory to operate on an array in CUDA? : <p>I've seen CUDA programs where you allocate memory on the device, operate on it, and then copy it back to the host, like this:</p>
<pre><code>float* h_a = (float*) malloc(numBytes);
float* d_a = 0;
cudaMalloc((void**) &a, numBytes);
cuda_function<<< N/blockSize, blockSize>>>(d_a);
cudaMemcpy(d_a, h_a, numBytes, cudaMemcpyDeviceToHost);
</code></pre>
<p>But then I've also seen code where the CUDA program just operates on memory whose reference was passed to it, like this:</p>
<pre><code>__global__ void cuda_function(int* a)
{
...<operate on a>...
}
int main()
{
cuda_function<<<N/256, 256>>>(a)
}
</code></pre>
<p>What's the different between these two approaches?</p>
<p>Thanks!</p>

How to check out a branch with GitPython : <p>I have cloned a repository with GitPython, now I would like to checkout a branch and update the local repository's working tree with the contents of that branch. Ideally, I'd also be able to check if the branch exists before doing this. This is what I have so far:</p>
<pre><code>import git
repo_clone_url = "git@github.com:mygithubuser/myrepo.git"
local_repo = "mytestproject"
test_branch = "test-branch"
repo = git.Repo.clone_from(repo_clone_url, local_repo)
# Check out branch test_branch somehow
# write to file in working directory
repo.index.add(["test.txt"])
commit = repo.index.commit("Commit test")
</code></pre>
<p>I am not sure what to put in the place of the comments above. The <a href="http://gitpython.readthedocs.io/en/stable/tutorial.html#switching-branches" rel="noreferrer">documentation</a> seems to give an example of how to detach the HEAD, but not how to checkout an named branch.</p>

How do you create a multi-line text inside a ScrollView in SwiftUI? : <p>Since <code>List</code> doesn't look like its configurable to remove the row dividers at the moment, I'm using a <code>ScrollView</code> with a <code>VStack</code> inside it to create a vertical layout of text elements. Example below:</p>

VStack {
// ...
Text("Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer mattis ullamcorper tortor, nec finibus sapien imperdiet non. Duis tristique eros eget ex consectetur laoreet.")
.lineLimit(0)
}.frame(width: UIScreen.main.bounds.width)
}
</code></pre>
<p>The resulting <code>Text</code> rendered is truncated single-line. Outside of a <code>ScrollView</code> it renders as multi-line. How would I achieve this inside a <code>ScrollView</code> other than explicitly setting a height for the <code>Text</code> frame ?</p>

<p>I have problems to access the a specific node_id to get its x and y values. My idea is to automatically add an <code>"id:"</code> before e.g. <code>"node_id_1"</code> and then to flatten the array.
Could you give me a hint how to add this <code>"id:"</code>? Or is there another elegant way to access the IDs?
Thank you a lot!

`scrub` returns the same result and `encode` resutls in an error.

Yii2 Rest API Bearer Authentication : <p>I've made a Yii2 REST API. With the API you can get a list of cars. Now I want to use the Bearer Authentication to protect the API. But I don't know how it works.</p>
<p>First of all. I set up the authenticator in the behaviors method of my controller.</p>
<pre><code>public function behaviors(){
return [
'contentNegotiator' => [
'class' => ContentNegotiator::className(),
'formats' => [
'application/json' => Response::FORMAT_JSON,
],
],
'authenticator' => [
'class' => CompositeAuth::className(),
'authMethods' => [
HttpBearerAuth::className(),
],
]
];
}
</code></pre>
<p>This works just fine. If I go to the URL I will get an 'Unauthorized' message. </p>
<p>In my wordpress plugin I've made an function to use the API and set the header with the authentication key. </p>
<pre><code>function getJSON($template_url) {
$authorization = "Authorization: Bearer " . get_option("auth_key");
// Create curl resource
$ch = curl_init();
// Set URL
curl_setopt($ch, CURLOPT_URL, $template_url);
// Return transfer as a string
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
// Set headers
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json', $authorization));
// $output contains output as a string
$output = curl_exec($ch);
// Close curl resource
curl_close($ch);
return json_decode($output, true);
}
</code></pre>
<p>But now my question is. How can I check in the API if this key is valid and give me the response. I want to search for the key in de database and if it exists it should also give me the id or email thats in the same row.</p>
<p>I have no idea how to do this.</p>

Capture video data from screen in Python : <p>Is there a way with Python (maybe with OpenCV or PIL) to continuously grab frames of all or a portion of the screen, at least at 15 fps or more? I've seen it done in other languages, so in theory it should be possible. </p>
<p>I do not need to save the image data to a file. I actually just want it to output an array containing the raw RGB data (like in a numpy array or something) since I'm going to just take it and send it to a large LED display (probably after re-sizing it).</p>

How to change the label of a row based on the most frequent label? : <p>This is apparently a simple problem but I can't figure out what function to use. Following are sample data: </p>
<pre><code>gg <- data.frame(ID = c(15,15,15,16,16,16, 16,17,17,17),
ADO = c(rep("T1", 4), rep("T2", 2), rep("T3", 4)))
</code></pre>
<p>The "ID" is the label or category of a particular "ADO". It should be unique to each ADO. But in this case it is not: </p>
<pre><code>> table(gg$ID, gg$ADO)
T1 T2 T3
15 3 0 0
16 1 2 1
17 0 0 3
</code></pre>
<p>I want to assign the most frequent ID to a particular ADO. So, my desired output is: </p>
<pre><code> ID ADO
1 15 T1
2 15 T1
3 15 T1
4 16 T2
5 16 T2
6 16 T2
7 16 T2

9 17 T3

Truth value of empty set : <p>I am interested in the truth value of Python sets like <code>{'a', 'b'}</code>, or the empty set <code>set()</code> (which is not the same as the empty dictionary <code>{}</code>). In particular, I would like to know whether <code>bool(my_set)</code> is <code>False</code> if and only if the set <code>my_set</code> is empty.</p>
<p>Ignoring primitive (such as numerals) as well as user-defined types, <a href="https://docs.python.org/3/library/stdtypes.html#truth" rel="noreferrer">https://docs.python.org/3/library/stdtypes.html#truth</a> says:</p>
<blockquote>
<p>The following values are considered false:</p>
<ul>
<li>[...]</li>
<li>any empty sequence, for example, <code>''</code>, <code>()</code>, <code>[]</code>.</li>
<li>any empty mapping, for example, <code>{}</code>.</li>
<li>[...]</li>
</ul>
<p>All other values are considered true</p>
</blockquote>
<p>According to <a href="https://docs.python.org/3/library/stdtypes.html#sequence-types-list-tuple-range" rel="noreferrer">https://docs.python.org/3/library/stdtypes.html#sequence-types-list-tuple-range</a>, a set is not a sequence (it is unordered, its elements do not have indices, etc.):</p>
<blockquote>
<p>There are three basic sequence types: lists, tuples, and range objects.</p>
</blockquote>
<p>And, according to <a href="https://docs.python.org/3/library/stdtypes.html#mapping-types-dict" rel="noreferrer">https://docs.python.org/3/library/stdtypes.html#mapping-types-dict</a>,</p>
<blockquote>
<p>There is currently only one standard mapping type, the <em>dictionary</em>.</p>
</blockquote>
<p>So, as far as I understand, the set type is not a type that can ever be <code>False</code>. However, when I try, <code>bool(set())</code> evaluates to <code>False</code>.</p>
<p>Questions:</p>
<ul>
<li>Is this a documentation problem, or am I getting something wrong?</li>
<li>Is the empty set the only set whose truth value is <code>False</code>?</li>
</ul>

R Studio- Linear Regression : I am trying to use the coef function in r, however I need to know how to use this function by extracting columns from a dataset. I tried coef(rain$spring, rain$autumn) but it returned a message saying I could not use $. The dataset is rain, the variables are spring and autumn. There is another dataset spring so I cannot simply attach the two variables.
Thanks! | 0debug |

Reversing numbers in lines, have a regex already need to modify it : So @horucrux came up with an amazing regex to make all numbers in each line backwards, but it doesnt work in all lines only some lines get made backwards, i noticed some lines start with numbers and they dont get inverted and some with words in the middle dont work either, please if anyone know hows to fix modify this regex, please help and thank you
Regex Horocrux provided
Step 1. Add a marker for the not-yet-inverted digits.
Find:
\b(\w+?)(\d+)\b
Replace:
$1§$2
You can choose other marker instead of §.
Step 2. Do Replace all enough times with these settings:
Find:
\b(\w+)§(\d*)(\d)\b
Replace:
$1$3§$2
Step 3. Delete all markers.
Find:
\b(\w+\d)§
Replace:
$1 | 0debug |
