Getting Authy back on Apple Silicon Macs

For some reason, Twilio has disabled the ability to install the iPad version of Authy on Apple Silicon Macs. With Authy Desktop also being discontinued, this means that there is no longer an official way to use the Authy app on macOS anymore. This guide is a workaround I found to trick sideloaded versions of Authy into signing in successfully, and using that with a sideloaded version of the Authy iPad app on macOS gives us the ability to use Authy on Mac again.

What's needed for this guide:

1. An iOS/iPadOS device with Authy installed normally
2. An Apple Silicon Mac with Authy sideloaded
3. mitmproxy
4. A decrypted and signed Authy IPA
5. Technical skill and patience

How to register Rancher managed Kubernetes clusters in Argo CD

Registering Rancher managed clusters in Argo CD doesn't work out of the box unless the Authorized Cluster Endpoint is used. Many users will prefer an integration of Argo CD via the central Rancher authentication proxy (which shares the network endpoint of the Rancher API/GUI). So let's find out why registering clusters via Rancher auth proxy fails and how to make it work.

Hint: If you are just looking for the solution scroll to the bottom of this page.

Why do i get an error when running argocd cluster add?

Questions are not from any actual exam!!!  



Q:  Create a job that calculates pi to 2000 decimal points using the container with the image named perl
and the following commands issued to the container:  ["perl",  "-Mbignum=bpi", "-wle", "print bpi(2000)"]
Once the job has completed, check the logs to and export the result to pi-result.txt.

Streaming your Linux desktop to Youtube and Twitch via Nvidia's NVENC and VAAPI:

Considerations to take when live streaming:

The following best practice observations apply when using a hardware-based encoder for live streaming to any platform:

1. Set the buffer size (-bufsize:v) equal to the target bitrate (-b:v). You want to ensure that you're encoding in CBR mode.

2. Set up the encoders as shown:
