The simplest option to find the `project-id`:
1. Right-click the main GitLab page of your project
2. Select "View Page Source" (`Ctrl + U` in Chrome)
3. Search for:
```txt
Project ID:
```
There you go.
I discovered that it is displayed depending on your role in the project. But GitLab apparently just “hide” it on the client side. |
The `jarModule` is intended as you suggested to hold third party libraries which can indeed be packaged inside skinny war artifacts.
I think it more come in needs when there is common dependencies between war modules inside a single ear one. |
**Context:**
Let's say i'm building a finance app where the transactions are linked (like blockchain).
In the sense, `Transaction 1` has no link, `Transaction 2` should have link to `transaction 1`, `Transaction 3` should have link to `transaction 2` and so on.
And these links should be specific to `accounts`. In the sense, `Account A` will have transaction its own transaction links and `Account B` will have its own.
**Implementation**
I want to use a queuing mechanism(Preferably RabbitMQ) to where these transactions are executed one after the other so that we don't need to worry about concurrency issues.
**Problems**
1. Problem with this approach is, if we have a queue for the entire application, then the amount of transactions increase drastically as we increase accounts.
2. To solve the first problem we can create queue per accounts so that we can execute these transactions concurrently per account. But problem with this approach is number of queues and consumers will increase. And, since accounts can be created at runtime, Adding listeners dynamically might be a problem (I may be wrong here).
So, I want to know if there are any ways we can solve the problem.
Your help is appreciated.

- Use `REDUCE` to iterate through the string
- Find the number of `-`s by (``REGEX``)``REPLAC``ing all characters that are not `-`( `[^-]`) with nothing and calculate the remaining `LEN`gth of the string. This is the number of times we need to iterate.
- In each iteration, we use `REGEXEXTRACT` using
- regex `"(.*?,)([^,]+)-([^,]+)(.*$)"` to get
- Capture group #1: `(.*?,)` - get `p`revious match ending with `,`, i.e., `1,2,`
- Capture group #2: `(\d+)` - get `s`tarting ``d``igit before the `-`, i.e., `4`
- Literal `-`
- Capture group #3: `(\d+)`- get `e`nding digit after the `-`, i.e., `10`
- Capture group #4: `(.*$)` - get remaining `s`u`f`ix until end of string `$`, i.e., `,12,15-19`
- Create the `SEQUENCE` of numbers between `s`tarting and `e`nding digit and `JOIN` the `p`refix and `s`u``f``fix.
- Repeat the above until all dashes are removed.
```
=REDUCE(
A1,
SEQUENCE(LEN(REGEXREPLACE(A1,"[^-]",))),

a,c,
LET(
res,REGEXEXTRACT(a,"(.*?,)(\d+)-(\d+)(.*$)"),

How top app updating the UI component without app update from play store? |

I have just resolved this issue. It appears that you may have used a Macbook M1 for the pip install process.
The solution involves not using a different runtime to build the layer file.
Use Docker to create an environment identical to that of your lambda function. For me, the issue is resolved.
If you use arm64 for lambda layer
```
docker pull arm64v8/ubuntu
docker run -it arm64v8/ubuntu
```
then create your layer file in docker
after that, copy to local and upload to aws lambda
```
docker cp {container_id}:{path_of_layer.zip} {local_path}
``` |
For this problem, I would like to model out this constraint in cplex.But I am not sure if the indexes that I put is correct or not. Can anyone help me to explain if I did it wrong. Here are some of my codes:
```
Data:

NbOperations = 10;
NbPeriods = 3;
LeadTime = [1,1,3,5,0,0,3,0,0,0];
{string} Products = ...;
int NbOperations = ...; range Operations = 1..NbOperations;
int NbPeriods = ...; range Periods = 1..NbPeriods;
int LeadTime[Operations]= ...;
dvar int+ Y[Products][0..NbOperations][Periods];
dvar int+ Xin[Products][-4..NbPeriods];
forall(p in Products,l in Operations,t in Periods)
ct3:
Xin[p][t-LeadTime[l]] == Y[p][l][t];
```
The LeadTime is the estimated lead time of l operation of product p. In my case, I am assuming the lead time is the same for all products.
I felt like the -4 there is wrong. But, I don't know how to change it.
Thanks in advance. |
You can do it in 2 different ways:
If you use `<androidx.fragment.app.FragmentContainerView` tag in xml, it is as follows:
```kotlin
class MainActivity : AppCompatActivity() {
private lateinit var navigationController: NavController
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
navigationController = supportFragmentManager.findFragmentById(R.id.fragmentContainerView)
?.findNavController()!!
NavigationUI.setupActionBarWithNavController(this,navigationController)
}
override fun onSupportNavigateUp(): Boolean {
return NavigationUI.navigateUp(navigationController, null)
}
}
```
[![enter image description here][1]][1]
Use is not recommended. If you use `<fragment>` tag in xml, it is as follows:
```kotlin
class MainActivity : AppCompatActivity() {
private lateinit var navigationController: NavController
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
navigationController = Navigation.findNavController(this,R.id.fragmentContainerView)
NavigationUI.setupActionBarWithNavController(this,navigationController)
}
override fun onSupportNavigateUp(): Boolean {
return NavigationUI.navigateUp(navigationController, null)
}
}
```
Note: It should be added to your `build.gradle` file.
```gradle
....
// Navigation
val nav_version = "2.7.6"
implementation("androidx.navigation:navigation-fragment-ktx:$nav_version")
implementation("androidx.navigation:navigation-ui-ktx:$nav_version")

1. If you're using [CSV Data Set Config][1] - it will read next line on next iteration of each virtual user. In order to read all values during 1st iteration - convert them into 29 columns instead of 29 rows
2. In case you cannot control the CSV file format the options are in:
- switch to [__CSVRead() function][2]
- or add a [JSR223 PreProcessor][3] as a child of the request and create the values using [Groovy language][4] like:
sampler.addField('00', '0100')
sampler.addField('02','52250000000015')

I use segmented picker in iOS which contains few items. When user tap on not selected item this item becomes selected. Some of items can contain sub items. So when user tap on already selected type I need to show modal window with subitems for choosing one of them.
But taps on already selected items of segmented picker are not handling. I tried to use "long press" but it not works as well.
I would like to use native iOS design that's why I don't want use "buttons" instead segmented picker.
So the question is how I can handle tap on already selected item of segmented picker for showing sub items to choosing one of them? It can be "long press" or other alternative which will be intuitive for user.
```

Hi. These are a por1tion of my bindings. My `AbstractPlayer` injects the `InputManager` and the `CharacterController` classes. Also, the `CharacterController` class injects the `InputManager` class and I want to get the same instance of `InputManager` that the `AbstractPlayer` class injects.
I tired using `inRequestScope` method but it didn't work and I'm getting the same instance of `InputManager` for both the local player and the opponent. |
How does inRequestScope method works? |

Okay, it was due to the missing `await` keyword:
```js
await producer.publishMessage("info", "somemessage");
await producer.publishMessage("info", "somemessage");

Use `keydown` and `keyup` to store state of `ctrlKey` and `shiftKey`. In case of the special key combo, we cancel the event and insert text to textarea in a patchy manner.
<!-- begin snippet: js hide: false console: true babel: false -->
<!-- language: lang-js -->
var ctrl = false
var shift = false
textarea.addEventListener('paste', function(ev) {
var clipboardData = (event.clipboardData || window.clipboardData);
var pastedText = clipboardData.getData('text');
if (ctrl && shift) {
pastedText = "*" + pastedText + "*"
ev.preventDefault()
// this code - i don't like it - because you can't ctrl+z
var cursorPosition = textarea.selectionStart;
var currentValue = textarea.value;
var newValue = currentValue.substring(0, cursorPosition) + pastedText + currentValue.substring(textarea.selectionEnd);
textarea.value = newValue;
textarea.selectionStart = textarea.selectionEnd = cursorPosition + pastedText.length;
}
})
textarea.addEventListener('keydown', function(ev) {
ctrl = ev.ctrlKey
shift = ev.shiftKey
})
textarea.addEventListener('keyup', function(ev) {
ctrl = ev.ctrlKey
shift = ev.shiftKey
})

If you want the words with Jack and there must be at least `Jack#` you can match the part of the string containing Jack# using a negated character class `[^,\n]*` excluding matching comma's or newlines.
If there is a match, then split the match on one or more whitspace characters and filter the result containing the word Jack using word boundaries `\b`
<!-- begin snippet: js hide: false console: true babel: false -->
<!-- language: lang-js -->
const text = 'A Jack# Jack#aNyWord Jack, Jack';
const regexpWords = /[^,\n]*\bJack#[^,\n]*/g;
const m = text.match(regexpWords);
if (m) {
const result = m[0]
.split(/\s+/)
.filter(s => s.match(/\bJack\b/));
console.log(result);
}
<!-- end snippet -->
<hr>
After the question was edited, you can match all words with Jack:
`\bJack[^,\s]*` or `(?<!\S)Jack[^,\s]*`
See a [regex demo](https://regex101.com/r/WGUnTE/1) for the matches. |
I have webservices hosted on server but I am using Retrofit to fetch data from the server but When I am running my app it is showing exception `Unresolve host` but when I am using the same Url in Postman and browser it is working fine.I have also add Internet permission in app manifest file.
Below is my code:
**RetrofitClient.java**
public class RetrofitClient {
private static Retrofit retrofit = null;
public static Retrofit getInstance(){
OkHttpClient okHttpClient = new OkHttpClient.Builder()
.connectTimeout(22, TimeUnit.SECONDS)
.readTimeout(22, TimeUnit.SECONDS)
.writeTimeout(22, TimeUnit.SECONDS)
.build();
if(retrofit == null)
retrofit = new Retrofit.Builder()
.baseUrl("https://adbhutbharat.com/")
.addConverterFactory(GsonConverterFactory.create(new GsonBuilder().setLenient().create()))
.addCallAdapterFactory(RxJava2CallAdapterFactory.create())
.client(okHttpClient)
.build();
return retrofit;
}
}
**ApiService.java**
public interface ApiService {
@GET("app/getAgents.php")
Call<List<Agents>> allAgents();
}
The above endpoint is working properly in postman and browser but not when requesting using retrofit in android to fetch data.
How can I resolve this error?

I am working on an indoor navigation application that involves two floor plan images: one is the original floor plan, and the other includes nodes and paths (used for navigation). Using Python and the OpenCV library, I have successfully extracted the XY coordinates of all nodes from the navigation floor plan. However, I am facing challenges when translating these coordinates to position a map pin on the ImageView in Android Studio.
When I attempted to position an ImageView as a map pin on a FloorPlan ImageView using these coordinate, the map pin does not align with the nodes as expected in the Android ImageView. The scaling and translation seem to be incorrect.
Here is my imageView:
```
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:id="@+id/floorPlan"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:adjustViewBounds="true"
android:src="@drawable/floor5" />
<!-- ImageView for the map pin marker -->
<ImageView
android:id="@+id/mapPin"
android:layout_width="30dp"
android:layout_height="30dp"
android:visibility="gone"
android:src="@drawable/map_pin" />
</FrameLayout>
```
Here is what i tried for scaling:
```
private void updateMapPinPosition(int xCoordinate, int yCoordinate) {
// Convert 30dp to pixels based on screen density
int pinSizeInPixels = (int) (30 * getResources().getDisplayMetrics().density);
// Get the ImageView and its dimensions
ImageView mapPin = findViewById(R.id.mapPin);
Drawable floorPlanDrawable = mapImageView.getDrawable();
if (floorPlanDrawable != null) {
// Get the dimensions of the drawable (the floor plan image)
int drawableWidth = floorPlanDrawable.getIntrinsicWidth();
int drawableHeight = floorPlanDrawable.getIntrinsicHeight();
// Get the dimensions of the ImageView (the view displaying the floor plan)
int imageViewWidth = mapImageView.getWidth();
int imageViewHeight = mapImageView.getHeight();
// Calculate the scale based on the drawable dimensions and view dimensions
float xScale = (float) imageViewWidth / drawableWidth;
float yScale = (float) imageViewHeight / drawableHeight;
// Scale the coordinates from the server to fit the ImageView
int scaledX = (int) (xCoordinate * xScale);
int scaledY = (int) (yCoordinate * yScale);
// Adjust the position of the map pin based on the pin size
scaledX -= pinSizeInPixels / 2; // Center the pin horizontally
scaledY -= pinSizeInPixels; // Anchor the pin to the bottom
// Use absolute coordinates to place the pin
FrameLayout.LayoutParams params = new FrameLayout.LayoutParams(
pinSizeInPixels, // Width in pixels
pinSizeInPixels // Height in pixels
);
params.leftMargin = scaledX; // X position
params.topMargin = scaledY; // Y position
mapPin.setLayoutParams(params); // Apply the layout parameters to the map pin
mapPin.setVisibility(View.VISIBLE); // Make the map pin visible
}
}

[Constraint][1]
For this problem, I would like to model out this constraint in cplex.But I am not sure if the indexes that I put is correct or not. Can anyone help me to explain if I did it wrong. Here are some of my codes:
```
Data:
Products = {P1 P2 P3};
NbOperations = 10;
NbPeriods = 3;
LeadTime = [1,1,3,5,0,0,3,0,0,0];
{string} Products = ...;

int NbPeriods = ...; range Periods = 1..NbPeriods;
int LeadTime[Operations]= ...;
dvar int+ Y[Products][0..NbOperations][Periods];
dvar int+ Xin[Products][-4..NbPeriods];
forall(p in Products,l in Operations,t in Periods)
ct3:
Xin[p][t-LeadTime[l]] == Y[p][l][t];
```
The LeadTime is the estimated lead time of l operation of product p. In my case, I am assuming the lead time is the same for all products.
I felt like the -4 there is wrong. But, I don't know how to change it.

In the WordPress core, WordPress uses the sanitize_title hook to apply its own filter (you can find that in this code):
https://github.com/WordPress/WordPress/blob/master/wp-includes/default-filters.php
The function it call is sanitize_title_with_dashes:
https://developer.wordpress.org/reference/functions/sanitize_title_with_dashes/
That's the function you are looking for. |
**service.py**

messages.add_message(request, messages.INFO, 'Goods "{}" {}.'.format(goods.name, act))
return redirect(request.META['HTTP_REFERER'])
else:
return HttpResponse("Wrong goods id", status=status)
What troubles me:
1. Can I transmit request from views.py to service.py? A view is
something that operates on request. In my logic, it is reasonable
not to transmit request out of view. Receive data from request,
transmit the data to the service.
2. What will create the message? In my logic, it is the responsibility
of the view. But the view doesn't know anything about the name of
the goods. Look here: this code will not work just because there is
no name of the goods for the message.
Well, anyway, the architecture of this code stinks. Maybe I should return from the service not the status code, but the name of the added goods?
How can I refactor this code?

Here is somewhat a basic question but the reason is not spelled out clearly anywhere.
Say we have 2 web applications running on `https://one.abc.com` and `htts://two.xyz.com`.
I visit `https://one.abc.com` and a page is displayed which has a button on it and when clicked, submits to `https://one.abc.com` and responds with a redirect to `htts://two.xyz.com`.
On `htts://two.xyz.com` there is another button and when clicked, submits to `htts://two.xyz.com` and responds with a redirect to `https://one.abc.com`.
As everything is happening over https, in both redirections, everything like URL, query params, headers are encrypted.
Using the above setup we can do data exchange between 2 web application using query params.Also, we can do data exchange with auto-form-post (dynamically create form and auto submit using js) instead of query params.
This technique is used in SAML, OIDC for SSO.
Why data exchange using redirection via query params/auto-form-post CANNOT be trusted even on https?
Please review the below answer and let me know if my understanding is correct.

I have this route defined:
Route::match(['get', 'post'], '/{class}/{function}/', [OldBackendController::class, 'apiV1']);
If I do this request:
POST /api/v2_1/wishlist/archive
Laravel enters int the `OldBackendController`, and the value of `$class` variable (in the controller), is this:
api/v2_1/wishlist
Why? It shouldn't enter in the controller, cause the request does not contains 2 variables, but 4.
The strange thing is if in the controller I print `$request->segments()` value, I get all 4 segment:
Array
(
[0] => api
[1] => v2_1
[2] => wishlist
[3] => archive
) |
Laravel controller does not get correct parameter from route definition, and enters in the wrong controller function |

There is a function inside which determines whether metadata is saved (by metadata I mean saving dtypes). When I save a Dataframe to a parquet file and then read data from that file I expect to see metadata persistence. I will perform this check in this way:
```
In [6]:(pd.read_parquet(os.path.join(folder, 's_parquet.parquet'), engine='fastparquet').dtypes == df_small.dtypes).all()
Out [6]: Fasle
```
```
In [7]: pd.read_parquet(os.path.join(folder, 's_parquet.parquet'), engine='fastparquet').dtypes == df_small.dtypes
Out [7]:
date True
tournament_id True
team_id True
members True
location False
importance False
avg_age True
prize True
prob True
win True
dtype: bool
```
If you look at the data types directly you can see the following result:
```
In [8]: df_small.dtypes
Out [8]:
date datetime64[ns]
tournament_id int32
team_id int16
members int8
location category
importance category
avg_age float32
prize float32
prob float32
win bool
dtype: object
```
```
In [9]: pd.read_parquet(os.path.join(folder, 's_parquet.parquet'), engine='fastparquet').dtypes
Out [9]:
date datetime64[ns]
tournament_id int32
team_id int16
members int8
location category
importance category
avg_age float32
prize float32
prob float32
win bool
dtype: object
```
And even if you compare the categorical data directly, you get the expected result.
```
In [10]: df_small['location'].dtypes == pd.read_parquet(os.path.join(folder, 's_parquet.parquet'), engine='fastparquet')['location'].dtypes
Out [10]: True
```
What could be the reason for this behavior? |

I'm writing a function that decodes a morse code message to plain text. The problem I'm running into, is that it doesn't add spaces where needed. Keep in mind that every morse code character/letter, is separated with a blank space and every full word, is separated by 3 spaces. I want the function to add a single blank space to the plain text when it detects 3 blank spaces in a row in the morse code. I can't figure it out so i've come here.
Here is the function as it is now.
public function decode($morseCode)
{
// 1 space between characters, 3 spaces between words
// split the string
$morseArray = preg_split('/\s+/', $morseCode, -1);
$plainText = '';
$blankSpaceCount = 0;
// set each string as a morse code character
foreach ($morseArray as $morseChar)
{
if ($morseChar != ' ')
{
// check if the morsecode character is in the array
if(isset($this->plainTextsByMorseCode[$morseChar]))
{
// if it is, convert it to the corresponding plain text
$plainText .= $this->plainTextsByMorseCode[$morseChar];
$blankSpaceCount = 0;
}
}
else {
$blankSpaceCount++;
if ($blankSpaceCount === 3)
{
$plainText .= ' '; // Append a single blank space
$blankSpaceCount = 0;
}
}
}
return trim($plainText);
}
If it helps, the phrase i'm trying to decode is as follows.
-.-- --- ..- ... .... .- .-.. .-.. -. --- - .--. .- ... ...
It says "YOU SHALL NOT PASS" and you can clearly see the triple blank spaces between the words and the singular blank space between the letters.

I have an HTML/CSS/JS website where I'm embedding facebook posts, and adding some text (with various info and action buttons) to the top of each post. I'm adding the text that goes above each post dynamically in Javascript, so that the embedded post (iframe) is in a separate container than the text that goes above it.
As you can see in the image below, the text is positioned as `absolute` so that it appears above the post, and not next to it. However, I can't seem to get the post to move *down* nor the text to move up in order to create some separation between them. Any help or ideas would be greatly appreciated!!

how do i detect 3 blank spaces in a string array |

## Need: `getDownloadURL` on external bucket
We have a Firebase/GCP project and we want to use the [`getDownloadURL` Firebase storage function][1] in Node.js to create a permanent signed URL for an object in a bucket in a different project.
Specifically, we have an asset bucket and we want to generate long-lived (forever) URLs for objects in it, but not make the bucket public otherwise. The asset bucket serves many projects and we want all those projects to all be able to generate URLs against the asset bucket (without having to do anything exotic).
## Error: Permission Denied
When we run the `getDownloadURL` we get the following error:
> "Error: Permission denied. Please enable Firebase Storage for your bucket by visiting the Storage tab in the Firebase Console and ensure that you have sufficient permission to properly provision resources."
The error suggests that we add the bucket to the Firebase project. When we attempt to add a bucket via the Firebase Console we can create or import a bucket, but it's not clear what "import" means (copy? move bucket across projects? etc), whether it would work across projects. We can't find any documentation indicating what this does or whether it would help, but it also seems unnecessary/irrelevant to the permissions question (which one would expect to be solved by IAM permissions).
## Attempted fixes
We've also found some suggestions that we've tried:
1. granted Storage Admin to firebase-storage@system.gserviceaccount.com on the bucket
1. [set storage rules to allow-all][2] on the Firebase project
1. grant Storage Admin on the bucket to the service account that runs the Firebase function
The error gives no useful indication of how to fix this, there's no apparent documentation on what permissions are needed, and most of the information from Google/etc is outdated or wrong.
## Workaround
As a workaround we've also considered using [long-lived V2 Signed URLs][3] but the documentation specifically says to keep it short-lived, and V4 Signed URLs have an arbitrary 7-day limit, but the `getDownloadURL` function would appear to be the correct/ideal thing to do here (if it worked).
How can we use `getDownloadURL` on an object in a bucket outside the GCP project?

Based on [Yoast SEO][1], it determine whether the title is too long based on its width instead of number of characters.
So, how to know the font, font size, and font style used in Google search results?
Also how to know the visible width for Google search results, from moz, it is said to be 600 pixels
```
procedure TMainForm.Button2Click(Sender: TObject);
var
Bitmap: TBitmap;
Width: Integer;
begin
Bitmap := TBitmap.Create;
try
// What is the font, font size, and font style used in Google search results?
Bitmap.Canvas.Font.Assign(Self.Font);
Width := Bitmap.Canvas.TextWidth('This is to test the title and to make sure it is not too long to be invisi');
// What is the max width of Google search results, based on https://moz.com/learn/seo/title-tag, it is 600pixels
Application.MessageBox(PChar(Format('Title width is %d', [Width])), 'Information', MB_OK);
finally
Bitmap.Free;
end;
end;

How can I make the circle roll instead of slide?

Yes, it's very easy to do this using `index_sequence`:
template<typename... Args, std::size_t... Is>
void foo_impl(std::index_sequence<Is...>, const Args&... args)
{
using typeLists = std::tuple<Args...>;
bar( SomeClass<Args, std::tuple_element_t<Is, typeLists>>{ args }... );
}
template<typename... Args>
void foo(const Args&... args)
{
foo_impl( std::index_sequence_for<Args...>{}, args... );

To successfully serve static files in production, I used WhiteNoise and deployed it to Azure App Service.
I used your git repo code and made the necessary changes.
To use whitenoise, I added the lines below in the settings. py file, as shown below:
Note: Add whitenoise middleware after the security middleware.
**settings. py**:
```python
INSTALLED_APPS = [
'otherInstalledApps
"whitenoise.runserver_nostatic",
]
MIDDLEWARE = [
'django.middleware.security.SecurityMiddleware',
'whitenoise.middleware.WhiteNoiseMiddleware',
'other middlewares'
]
STATIC_ROOT = BASE_DIR / "static"
STATIC_URL = "static/"
STATICFILES_DIRS = [
BASE_DIR / "assets"
]
STATICFILES_STORAGE = ('whitenoise.storage.CompressedManifestStaticFilesStorage')
```
I added the white noise to the requirements.txt file, as shown below.
**requirements.txt**:
```html
Django==4.2.1
requests==2.31.0
whitenoise==6.6.0
```
I ran the commands below to install whitenoise and collect static files for production.
```
pip install whitenoise
python manage.py collectstatic
python manage.py migrate
```
**LocalOutput**:
It was deployed successfully to azure app service.

I've been using Firebase for several years now and have recently set up a new project to run with Firebase.
The problem occurs when I try to run `firebase deploy`.
I get the errors:
`[project root]/functions/.eslintrc.js`
`0:0 error Parsing error: Cannot read file '[project root]/functions/functions/tsconfig.json'`
and
`[project root]/functions/src/index.ts`
`0:0 error Parsing error: Cannot read file '[project root]/functions/functions/tsconfig.json'`
I tried replacing
```"functions": {
"predeploy": [
"npm --prefix "$RESOURCE_DIR" run lint",
"npm --prefix "$RESOURCE_DIR" run build"
]
}
```
with
```"functions": {
"predeploy": [
"npm --prefix ./functions/ run lint",
"npm --prefix ./functions/ run build"
]
}
```
as per this answer https://stackoverflow.com/a/48591027/5348742,but I still get the same error.
If I checkout my previous commit, it works fine but using DIFF, I can't find any difference that could change the behaviour.
The `firebase.json` files are identical in the two versions.

Get Width of Title Like Yoast SEO does |

As the first step of a larger process, I'm trying to get the column names from some .dat files. I'm getting the "FileNotFoundError: [Errno 2] No such file or directory:" error, but I'm passing it the directory path and it is telling me the first file in the folder, so it doesn't seem to be the usual suspect of the relative/absolute path issue.
dir_path = "C:/Projects/acs5-2022/Datasource/TestSample"
column_list = []
for path, subs, file_names in os.walk(dir_path):
for file in file_names:
datafile = pandas.read_csv(file, delimiter='|')
for col in datafile.columns:
col.append(column_list)
print(column_list)
And I get:
FileNotFoundError: [Errno 2] No such file or directory: 'acsdt5y2022-b02009.dat'
acsdt5y2022-b02009.dat is the first file in the TestSample folder. I'm not giving it that information, so it can, in fact, see the files.
The header in this particular file is GEO_ID|B02009_E001|B02009_M001
I've tried various formats for the path directory - "C:/.....", r"C:\.....", "C:\\....." - it doesn't seem to matter.
Any suggestions? Is it the .dat format? Is it the pipes? I'm using PyCharm and I've seen some posts on that, but again, I'm specifying the directory.
Thank you in advance for any direction you can give me!

The answer with `declare global { ...` didn't work out for me.
The recommanded approach is to create a type declaration file, for example `env.d.ts` with the following declaration:
```ts
declare namespace NodeJS {
interface ProcessEnv {
JWT_TOKEN: string;
}
}
```
And then add this reference in your `tsconfig.json` file's `include`:
```json
{
"include": [
"next-env.d.ts",
"env.d.ts",
]
}
```
**Discouraged approach**
Do not add a reference in `next-end.d.ts`, Next.js [docs mention][1] that:
> A file named next-env.d.ts will be created at the root of your project [...] You should not remove it or edit it as it can change at any time.
Instead, please use a recommended approach:
> Instead of editing next-env.d.ts, you can include additional types by adding a new file e.g. additional.d.ts and then referencing it in the include array in your tsconfig.json.

Using a *hacky* [`defaultdict`][1] :
```
from collections import defaultdict
genid = defaultdict(lambda: len(genid) + 1)
out = {
k: v if v in ("VDD", "GND")
else genid[v] for k, v in my_dict.items()
}
```
Output (*before/after*) :
```
{ # {
"1": "VDD", # "1": "VDD", # < unchanged
"2": "VDD", # "2": "VDD", # < unchanged
"7": "VDD", # "7": "VDD", # < unchanged
"0": 0, # "0": 1, # < updated : grp1
"3": 0, # "3": 1, # < updated : grp1
"4": 0, # "4": 1, # < updated : grp1
"6": 9, # "6": 2, # < updated : grp2
"13": 9, # "13": 2, # < updated : grp2
"GND": "GND", # "GND": "GND", # < unchanged
"15": "GND", # "15": "GND", # < unchanged
"12": 12 # "12": 3 # < updated : grp3
} # }
```

You certainly can use `parfor` in the functions invoked using `parfeval`. It is difficult to do this in a non-trivial manner in R2019b though. In later releases of MATLAB (>=R2020a), you can use a [thread pool][1] inside each local process worker. It's awkward to set up though, and even then there might be challenges getting everything you need running on thread-pool workers.
The approach I would explore is converting your `select_data` so that you can run it directly in chunks inside `parfeval`. I.e. instead of something like this
```matlab
function out = select_data(in)
parfor i = 1:n
out(i) = dostuff(i);
end
end
```
You somehow work out how many iterates you need and then effectively call the guts of the `parfor` loop directly from the client via `parfeval`, like this:
```matlab
for i = 1:n
fut(i) = parfeval(@dostuff, 1, i);
end
fetchOutputs(fut);
```
This also would let you use e.g. [`afterAll`][2] on the array of futures to do something else asynchronously once the work is all finished.

You can get index of selected item and then remove that item from your list and insert that removed item into your list(now it appears as the first element in your list).
for example, selected item index is 5
myList.removeAt(5) // 5 is your selected item index
then
myList.insert(0, element) // element is type of your list(if your list type
//is string then element type will be string like "A" if it is a model
//class, then it will be model class)
**Happy Coding :)**

I'm normally very comfortable performing joins in my work/on online practice sets but sort of blanked when I got this question.
Here's the data: The image for the data set > (https://i.stack.imgur.com/iUmN0.png)
I was asked to perform a select * statement on the two tables, and write down the result for all 5 kinds of joins.
So basically:
select * from table_a a left join table_b b on a.column_a = b.column_b
For this I answered: 1 1 0 0 1 1 1 1 0 0 null
Can somebody tell me if the answer is wrong/right?
Also, can you please list down the output for all 5 types of joins (left, right, inner outer, cross) for this? With a good explanation
Any help would be appreciated!

This works:
if exist %1\* echo Directory
Works with directory names that contains spaces:
C:\>if exist "c:\Program Files\*" echo Directory
Directory
Note that the quotes are necessary if the directory contains spaces:
C:\>if exist c:\Program Files\* echo Directory
Can also be expressed as:
C:\>SET D="C:\Program Files"
C:\>if exist %D%\* echo Directory
Directory
