no-internet | Checking if the internet is accessible in the browser | Proxy library

Windows Hello may meet your requirement. It works with the Azure Active Directory account or Microsoft Account connected in Windows settings, and it replaces passwords with strong 2FA by verifying your biometric. Besides, in Windows Hello architecture you no longer need to host your Ory Kratos OAuth2 server.

I solved my problem it was all because of Context,Dialog using different context, I solve it by using StatefulBuilder so the dialog must be like this

Congratulation that you have found the solutions:

Seems that the android emulator had an issue with DNS. Following Android Studio - Android Emulator Wifi Connected with No Internet this thread I was able to manually set my DNS to 8.8.8.8 and 8.8.4.4 which resolved the issue.

I post this as answer and this can be beneficial to other community members.

QLCDNumber Class - Inherits: QFrame.

QFrame Class - Inherits: QWidget.

No need to create each time - self.network = QLabel (self).

You do not need global variables.

Try it:

HTMLCanvasElement.captureStream returns a MediaStream. This MediaStream is initially composed of a special kind of MediaStreamTrack: a CanvasCaptureMediaStreamTrack which is simply a special video track with a link to the original HTMLCanvasElement.

This may still sound foreign language at this stage...
A MediaStream is a container object holding tracks themselves holding a stream of raw data, which are part of a media. An audio track will hold a stream of raw audio data, a video or canvas one will hold a stream of raw video data.

Tracks can be added or removed from a MediaStream, so that the MediaStream that was fed by a webcam's video be changed to a video coming webRTC etc. This is what the the onaddtrack event monitors: when a MediaStreamTrack is added to the MediaStream container.
It has nothing to do with frames being appended to the video stream, for the MediaStream, it is either streaming or paused.

So your MediaStream holds a stream of video data, generated from the canvas current state.
Captured stream from canvas have this special that you can require at which maximum frequency the browser should append new frames to the video stream. However this is just a maximum; if nothing new has been painted on the canvas, then no image will get appended, and the stream will continue to display the last image that got appended.

I don't think there is any way to know when this operation happens, but even if there was one, your process would be too much convoluted.

1. draw on canvas1
2. capture stream
3. render stream in
4. draw on canvas2
5. process the image drawn on canvas2

While all you need is

1. draw on canvas1
2. process the image drawn on canvas1

If you want to do it at a certain frame-rate, then set up a timeout loop.

The problem was in Docker updating, instance rebooting and the file /etc/docker/daemon.json with {"iptables": false} created by the previous maintainer. These things were overlapped by each other.

I have found the solution in this answer.
Or more described in this article.

So if I understand your scenario correctly, you would like to avoid sharing your host's network to your gitlab container to make sure gitlab cannot connect to the internet. At the same time you wish to share the host's network to bind a container port to your host system. It doesn't work that way, but the following might be an acceptable workaround for you: docker containers sharing the same internal network can connect to exposed/published ports of other containers on the same network.

You could follow this approach:

• Run a reverse proxy in front of your gitlab container
• The reverse proxy is member of your internal network and the default bridge network (which includes the host's net)
• This enables the reverse proxy to bind to a host port and forward requests to your gitlab container while gitlab still can't access the internet

I quickly put this example together, hope that gets you started:

docker network create --internal --subnet 10.1.1.0/24 no-internet

docker network create internet

docker-compose.yml:

Use this method to check internet connection

While restarting docker doesn't work, I solved it by reinstalling docker using curl like @isp-zax said.
