When I launch in VSCode dlv dap debug, I get this message:

After upgrading to android 12, the application is not compiling. It shows

"Manifest merger failed with multiple errors, see logs"

Error showing in Merged manifest:

Merging Errors: Error: android:exported needs to be explicitly specified for . Apps targeting Android 12 and higher are required to specify an explicit value for android:exported when the corresponding component has an intent filter defined. See https://developer.android.com/guide/topics/manifest/activity-element#exported for details. main manifest (this file)

I have set all the activity with android:exported="false". But it is still showing this issue.

My manifest file:

I am running a Spring Boot app that uses WebClient for both non-blocking and blocking HTTP requests. After the app has run for some time, all outgoing HTTP requests seem to get stuck.

WebClient is used to send requests to multiple hosts, but as an example, here is how it is initialized and used to send requests to Telegram:

WebClientConfig:

I have created a new flutter project and added camera plugin. after adding that dependency I got many errors. I used futter version is 2.5.2 & minSdkVersion 21

In pubspec.yaml file,

We have an enterprise account, and till iOS 14 there were no issues, but as soon as user update their phones to iOS 15, they are getting this alert.

The Developer of this app needs to update it to work with this version of iOS

Now, this issue is coming only for enterprise apps running on iOS 15. I have done some research and found this article. https://developer.apple.com/documentation/xcode/using-the-latest-code-signature-format.

In here it states that

To check whether an app called MyApp.app has the new signature, you can use the

codesign utility: % codesign -dv /path/to/MyApp.app

Look in the output for a string such as CodeDirectory v=20500. For any value of v less than 20400, you need to re-sign your app.

I did that and my output was indeed v=20400. I have signed the app using Xcode 12.5 running on Mac OS 11.2.3. I don't think Apple documents are correct for this. (I could be wrong)

Can anyone please help and let me know, what exactly we need to do to get this issue fixed?

EDIT: I was able to solve this issue by upgrading OS to Big Sur. Xcode version was 12.5.

Because of Google Play, I had to update an old project of mine to the latest expo versions (version 43.0.0 to be exact). The idea is for the app to scan a QRCode and process the data, simply. However, expo-barcode-scanner only works once and after that I need to close and open the app again to work. Has anyone encountered this problem and (or) knows how to solve it? Below is my code:

First, the question: is there a way to choose the platform (e.g. x86_64, AMD64, ARM64) for a GitHub Codespace?

Here's what I've found so far:

Attempt 1 (not working):

From within GitHub.com, you can choose the "machine" for a Codespace, but the only options are RAM and disk size.

Attempt 2 (EDIT: not working): devcontainer.json

When you create a Codespace, you can specify options by creating a top-level .devcontainer folder with two files: devcontainer.json and Dockerfile

Here you can customize runtimes, installed packages, etc., but the docs don't say anything about determining architecture...

...however, the VSCode docs for devcontainer.json has a runArgs option, which "accepts Docker CLI arguments"...

and the Docker CLI docs on --platform say you should be able to pass --platform linux/amd64 or --platform linux/arm64, but...

When I tried this, the Codespace would just hang, never finishing building.

Attempt 3 (in progress): specify in Dockerfile

This route seems the most promising, but it's all new to me (containerization, codespaces, docker). It's possible that Attempts 2 and 3 work in conjunction with one another. At this point, though, there are too many new moving pieces, and I need outside help.

1. Does GitHub Codespaces support this?
2. Would you pass it in the Dockerfile or devcontainer.json? How?
3. How would you verify this, anyway? [Solved: dpkg --print-architecture or uname -a]
4. For Windows, presumably you'd need a license (I didn't see anything on GitHub about pre-licensed codespaces) -- but that might be out of scope for the question.

I have a simple chat app using Firebase v9, with these components from parent to child in this hierarchical order: ChatSection, Chat, ChatLine, EditMessage.

I have a custom hook named useChatService holding the list of messages in state, the hook is called in ChatSection, the hook returns the messages and I pass them from ChatSection in a prop to Chat, then I loop through messages and create a ChatLine component for every message.

I can click the Edit button in front of each message, it shows the EditMessage component so I can edit the text, then when I press "Enter", the function updateMessage gets executed and updates the message in the db, but then every single ChatLine gets rerendered again, which is a problem as the list gets bigger.

EDIT 2: I've completed the code to make a working example with Firebase v9 so you can visualize the rerenders I'm talking about after every (add, edit or delete) of a message. I'm using ReactDevTools Profiler to track rerenders.

• Also deployed on: Netlify

ChatSection.js:

For my research I need to cURL the fqdns and get their status codes. (For Http, Https services) But some http urls open as https although it returns 200 with cURL. (successful request, no redirect)
