You don't need to write any dynamic code; simply add this line to your project's themes.xml file: <item name="android:navigationBarColor">@color/your_color</item>. This way, you won't need to use deprecated functions.

Auth::user() returns \Illuminate\Contracts\Auth\Authenticatable|null. Which does not have your method.

You can safely ignore this message. Personally I use https://github.com/barryvdh/laravel-ide-helper Which resolves such issues by rewriting the expected output to your User model.

You could just add each selected PRODUCT_ID to some list, and base the Interactive Grid on that list. The list could be a (hidden) item containing colon seperated values, an Apex collection, or whatever else you fancy.

I had the same problem with Python 3.13.2. I installed Python 3.12.9, and the installation of the requirements passed smoothly. Unfortunately, I couldn't (or didn't have time to) figure out what's broken with the dependencies.

this removed the error for me npm install @types/react --save

This error occurs in the latest version 13.0.1. Tried to downgrade to 11.0.2 or 12.0.1 and solved the issue.

In package.json change: "koa-router": "11.0.2" and remember to remove the "^"

I have not check detailed on the document, maybe this changed to other syntax?

The 9's complement of 0.473 in base 10 is 9.526. The 9's complement of 9.473 in base 10 is 0.526.

You just had a minor miscalculation for the 9's complement of the number 0.473: 10^1 - 10^(-3) - 0.473 = 9.526

Go to your Project folder and if it is saved in iCloud do a right click and choose download. Now Xcode can compare it to your local repository. Otherwise a restart of Xcode does work most of the time.

I've been using yfinance for years without this issue and it just started yesterday, so this is something new! Please help find a fix. Is there an old version, I can load? or something?

I stumbled across the answer to this question on a hunch so posting the solution in case anyone else has the same issue.

In GitHub, TFLint relies on the GITHUB_TOKEN automatically generated by the workflow to authenticate with the GitHub API.

So in an attempt to replicate this, I created a new GitHub PAT, and added it to my GitLab pipeline as a variable named GITHUB_TOKEN. Then in the pipeline script, before I call TFLint I added the following line:

GITHUB_TOKEN=${GITHUB_TOKEN}

Since the answers above did not work with Laravel 11, I decided to write my own

public static function getPossibleEnumValues(string $column): array
{
    $table = (new static)->getTable();
    $columnType = DB::selectOne("SHOW COLUMNS FROM {$table} WHERE Field = ?", [$column])->Type;

    if (preg_match('/^enum\((.*)\)$/', $columnType, $matches)) {
        return array_map(
            fn($value) => trim($value, "'"),
            str_getcsv($matches[1], ',', "'")
        );
    }

    return [];
}

the problem is definitely related to the backend because port 9060 is usually listened there

For me the solution was to upgrade my function from net6.0 to net8.0 rebuild and deploy + setting the environment variable to "dotnet-isolated" instead of "dotnet" in the portal (it ignored my local.settings.json file).

1. Clean & update gradle cache:

   • delete the gradle cache:
     • windows: delete C:\Users\<YourUsername>\.gradle\caches
     • mac/linux: delete ~/.gradle/caches
   • run from project root:

     ./gradlew cleanBuildCache
     ./gradlew clean
     

   • in android studio, use File > Invalidate Caches / Restart.
   • update your gradle settings (check gradle-wrapper.properties and build.gradle).

2. Resolve unresolved references:

   • check Missing Files/Resources.

3. Rebuild the project:

   • clean and rebuild your project via android studio.

This should fix the cache corruption and compilation issues, but if that didn't work, check this detailed solution on StackOverflow.

now we import vpython rather than import vis library.

And now the axis is same as the x axis, up axis is same as y axis.

Euler angle (that is, the roll, pitch, and yaw you are using now) can be convert to a rotate matrix, and my method is use rotate matrix to assign the vector to up and axis.

So first you need to do the convertion of euler angle to rotate matrix. You can google this and find the convert method.

Now, all you need to do is split a rotate matrix to x, y and z vector, and assign y to up, and x to axis.

Say, you have a rotate matrix (I don't know how to use a latex matrix in stackoverflow, so you see this):

    r11 r12 r13
R = r21 r22 r23
    r31 r32 r33

and x vector would be a column vector of the first column:

    r11
x = r21
    r31

and y vector would be the second column, z vector would be the third column:

    r12      r13
y = r22, z = r23
    r32      r33

After that, you just neet to do this in your python code:

element.axis = x
element.up = y

(sorry about my bad english)

Web scraping using Google sheets

After trying different ways to scrape the given website using other ways in Google sheets and even in Google Apps Script, it seems that it is not possible to accomplish your goal by just utilizing Google sheets functions or the website that you are trying to use implements some type of anti-scraping mechanisms. With that, you will need to look for alternatives like using different tools see this or using alternative websites.

Following @Tedinoz comment, it is indeed that the website uses Javascript to render dynamic websites. We can confirm that by disabling JavaScript on the web browser, in my case, Google Chrome. See below

After disabling JavaScript

The image above suggests that the website uses JavaScript to render most of its data which are the data that you are interested in.

Reserving more spaces to make it a full cache line probably won’t make a performance difference.

More importantly, you should align this structure to a cache line. If the structure spans multiple cache lines, it may waste cache memory. (Though, whether this leads to significant performance degradation is questionable.) Additionally, depending on the processor architecture, spanning multiple cache lines could lead to increased cache misses or excessive memory bandwidth usage during writebacks.

In any case, if your performance requirements are extremely strict, it might be worth testing and comparing to see if there is any actual performance difference.

Indeed, metadata_startup_script runs every time the machine boots, but you can add set an environment variable (maybe something inside .bashrc like $INIT_RUN=1) the first time you run it, and skip running it when the variable is already set.

I too was having this very issue and the thing that solved it for me was passing the toolset while creating the run.

project_client.agents.create_and_process_run(thread_id=thread.id, assistant_id=agent.id, toolset=toolset)

For the latest Mac Users in VS code:

You got it correct. Each partition will allow 1 task to subscribe. A single task can subscribe to many partitions, but one partition can have 1 task for the same connector.

Whether there are different topics or not, only total number of partitions should matter. For your case, 17 tasks for 17 partitions is what you needed to do.

How did you check if they are all assigned to task-0? If you are sure about that, there maybe a consumer assigning issue with your custom connector.

how do i modify this to be 3 years please :)

The issue you're facing is likely due to missing getter and setter methods in your Java class. Ensure that your class has public getter and setter methods for the fields that need to be serialized to JSON.

Alternatively, you can use Lombok, which provides convenient annotations like @Data, @Getter, @Setter, and @AllArgsConstructor, so you don't have to manually write all the getter, setter, and constructor methods. Adding Lombok to your project can simplify your code and save time.

If you want to configure the Kong Ingress Controller as an internal load balancer, ensure that everything is set up correctly in the YAML files as mentioned above. I encountered a similar issue in one of our client projects and resolved it by switching the VPC network from Regional to Global mode in Google Cloud. This is necessary only if you want to expose services via a domain and access them through an internal load balancer from your browser.

Also stuck with the same problem :\

You can try these troubleshooting steps for default backend not working in GKE Ingress setup:

Since your configuration seems fine. You might have to check the logs of Ingress controller to confirm that the request is received by the controller and rerouting the traffic to the default backend.

You can get the logs from the GKE Ingress controller with:

$kubectl logs -n kube-system -l app=gke-ingress

You need to check the health check logs as well, follow this document to enable the health check logging and check the state of your health check by using this document as reference.

Check this official gcp health check troubleshooting document to troubleshoot your health check

Note: Sometimes there may be issues with the GKE ingress controller not properly syncing with the Google Cloud load balancer or health checks. Try deleting and recreating the Ingress resource and the associated services.

Delete the Ingress:

kubectl delete ingress ydt-ingress -n ydt

Reapply the Ingress configuration:

kubectl apply -f your-ingress-config.yaml

the problem was that my if statement:

if (envoi?.paid && envoi?.trackingNumber && envoi?.qrCodeUrl && envoi?.simulationStatus === SimulationStatus.COMPLETED)

which doesn't run because my api backend return an object that contains another object, the soulution i should change my if statement for exemple to be: if(envoi?.envoi.paid) instead of: if(envoi?.paid) Or, update the api response to return directly the 'envoi' object instead of returning it in another object like i had before : return NextResponse.json({envoi: envoi}, {status: 200});

I have the same problem after I search for documents in alfresco share under project libary :(

Check the .csproj File: Make sure that the paths to the NuGet packages are correct and that they are included for both target frameworks. You might need to add conditional references if the paths differ between frameworks.

I think the issue is that Uvicorn (if you're using it) does not trust proxy headers by default unless specified.

According to the FastAPI documentation about deploying FastAPI on Docker behind a proxy, you need to enable proxy headers.

Additionally, Starlette provides information about Uvicorn middleware for handling proxy header. The Uvicorn GitHub code also provides insight into how proxy headers are processed.

In react, you need to use states

const [width, setWidth] = useState<string>("100%"); // initial value.

const method: () => void = () => {
   setWidth("70%"); 
};

useState is a hook you can import as import { useState } from 'react';

There is one more way to solve this issue my deleting .pnp file where you will find in folder of window (C) =>> user ==>> (name) if multiple user if not after user you will find the fill .pnp if still not get unhidden all files you will and delete the file and restart the server means ng serve

Starting with Android 9 (API level 28), cleartext support is disabled by default. You need to establish connection via https, otherwise you need to allow your app to make unsecure requests - add the following property in your Android app manifest: android:usesCleartextTraffic="true"

brew reinstall gcc did not work for me. I tried brew uninstall gcc && brew install gcc, which did not solve the issue either.

I had to edit my ~/.R/Makevars file and add -L/opt/homebrew/Cellar/gcc/14.2.0_1/lib/gcc/current/gcc/aarch64-apple-darwin24/14/ to LDFLAGS.

I am novic. But, for me trying this solution worked: https://weepingfish.github.io/2020/07/22/0722-suppress-tensorflow-warnings/ But only after restarting the environment so the import takes a few seconds and not immediate. I hope this helps.

try to remove your .gradle, and build again

I also encountered the same error and was using Expo Go. I decided to make a new build and update our devices that I use for testing: eas build --platform android --profile development.

From what I can check the build version previously installed on my devices that did not have the storage module installed.

This answer will be valid for anyone using EAS

You could use the exclude parameter of distance if you use a single raster. To do that, set the cells that overlap the target points to a value different from the rest of the raster:

library(terra)
# create dataset
r <- rast(ncols=36, nrows=18, crs="+proj=longlat +datum=WGS84")
r[1:200] <- 1
p2 <- vect(rbind(c(30,-30), c(25,40), c(-9,-3)), crs="+proj=longlat +datum=WGS84")

# set values of cells overlapping points to -1
r[cells(r,p2)[,2]] <- -1
dist <- distance(x = r, target = 1, exclude= NA)
plot(dist)

I see the same issue today for me, which has not happened earlier. It is consistently giving 429 status. Will try from another location and check. I hope they have not stopped the yfinance free service :)

I know I'm late for this question, but how about this one ?

from([1, 34, 65, 3, 7]).pipe(
    filter(item => item > 10),
    isEmpty(),
    map(hasNone => !hasNone),
).subscribe((e) => console.log(e))

It is solely based on RxJS operators, and has the advantage of closing the source as soon as one value passes the test.

I think I'm trying to do something similar and may have found what you're looking for. I'm using the AppRequests table, and found it has a hidden column _ItemId that is the eventId used in the end-to-end transaction URL.

I found @Anil kumar comment useful so I have posted it as an answer.

I have exactly the same problem. I want to create a simple Dataset in Java, but use a POJO class which I generated with ByteBuddy before. Then, I get the issue you described. It works, when I use a POJO class which is compiled within the JAR file i am executing with spark. See my code snippet here:

            final GenericRowMapper genericRowMapper = new GenericRowMapper(dynamicType);
            applyParquetDefaults(
                spark.createDataset(new ArrayList<>(), kryo(dynamicType))
                  .map(genericRowMapper, genericRowMapper.getEncoder())
                  .writeTo(join(".", db, tableName))
            ).create();

Did you find any solution to your problem?

In my case, static ones were completely dark but dynamics were working normally, clearly during baking all that lighting information affected every static object.

It is possible that your lighting data asset is missing or pointing to the wrong one. Very unusual, extremely dark (even on vertexLit textures) may appear very dark after baking in a scene.

Go to the Lighting Settings, and check your lighting settings assets. It is probably missing even if it is not you can create a fresh one and bake it again.

After I looked at your image, realized that your static objects might be using baked data and dynamics are using real-time. You can change direction-lights color and check which objects/shaders are being effected. Or you can just wipe lighting data Rendering->Lighting->Scene tab->Button right bake button left drop down->Clear Baked Data

I don't think we did have a correct answer, all of you. I may have a suggestion, but I am afraid of from Vietnam, you think me "advertise, be boastful". If you use "memory-mapped", you must synchronize (semaphore, mutex, spinlock, ...) but it makes your application slow. Then, "memory-mapped" is not a correct answer.

Ensure no other debugger is running by checking and terminating active debug sessions in Task Manager. Restart Visual Studio Code and try debugging again. Modify launch.json by adding "subProcess": true under "configurations". Try running with Administrator privileges. If using WSL, verify compatibility between Windows and Linux debugging environments.

I changed the build type to Debug and used O0 to deactivate optimization by the compiler. After making these changes, there were no more crashes.

Seems like optimization caused some undefined behavior...

I identified and resolved the audio stuttering issue in my decodeAudioData function. The problem was caused by incorrectly calculating the number of samples to be copied into AVAudioPCMBuffer. Initially, I used frameCount as the byte count, but I overlooked that the audio is stereo with two channels. To correctly process the data, the total number of samples must be calculated by multiplying frameCount by the number of channels.

data.withUnsafeBytes { (bufferPointer: UnsafeRawBufferPointer) in
    if let memory = bufferPointer.baseAddress?.assumingMemoryBound(to: Int16.self) {
       inputBuffer.int16ChannelData?.pointee.update(from: memory, count: Int(frameCount * inputFormat.channelCount))
    }
}

Thanks to Gordon Childs for pointing out that I was recreating the audio converter each time. For better efficiency and performance, it's best to instantiate it once in init().

JSON requires double quotes. You can make this swap in the text using REPLACE().

The default mapping for Enums is using an Integer. If you want to save them as a String, you need to add @Enumerated(EnumType.STRING) Annotation above your Enum field.

There’s a new native modifier for creating inner shadows, which can even be used on strokes like this:

    var body: some View {

                    lineWidth: 50)
            .frame(width: 300, height: 300)
    }

The result might look like this:

You can simply create a method in your viewset using UpdateModelMixin called

@Ivan Petrov answer did the job, also his answer made me thing using options pattern with default values for fields which looks like this:

public class PVO_HttpClientBasicConfig
{
    public string HttpClientName { get; set; } = "PVO_HttpClient";
...
}

So if there is no key of HttpClientName in appsettgins.json it will use the default value from class definition -> this won't work for null values in appsettings.json

I've solved it.

I tried installing it from the same Debug folder of my project and running it from the services screen. Then I attached it to process and it worked perfectly.
