• How to request GraphQL endpoint: https://docs.github.com/en/graphql/guides/forming-calls-with-graphql
• Octokit GraphQL client: use this for JS instead of own fetch()-based code, as it follows GitHub best practices
• GitHub doesn't allow unauthenticated GraphQL requests. How

Compression

• take your minified JSON and turn it into a URL safe base64 string. The length of this string can be as big as this.
• make a dummy url like http://dummy.tld/<the base64 string> and shorten it using any URL shortener.
• save the unique path of the shortened url as your compressed data (henceforth called token). No need to store the domain of the shortened URL as the URL shortener would be hardcoded in your app.

Decompression

1. Reconstruct the shortened URL from the token. Try to fetch (GET) the shortened URL.
2. Parse the response for the redirect url and extract the base64 string.
3. Decode the base64.

WSL2 to Windows

1. Obtain the IP address of your host machine (Windows) by running this command from your Linux distribution:

cat /etc/resolv.conf

Uninstall then reinstall WSL on Windows 10 (clean way)

Background

I've been using wsl (version 2) with genie mod for years without issue, but one day, Windows 10 finally catch up on wsl Windows 11 features and gives us a way to use systemD natively.

I wanted to use the new "right way" to enable systemD on Windows Subsystem for Linux (without genie), and I also had a (probably related) infinite Windows RemoteApp error poping in.

Fixing it

A - Uninstall wsl and related stuff

1. In powershell (as admin)
