TigerVPN with a Non-broken Open-source App

If you got set up on the TigerVPN years back you may have noticed that their Android app no longer works. It’s an often-reported issue. Ironically, the not-officially-supported setup documented here does still work. A similar quick setup can get you set up quickly on Android:

Hacktoberfest 2021 is here!

It’s been one year since the spammageddon of Hacktoberfest requests and issues with contributing to only accepted opted-in repositories – but this year there are some good changes:

You can now use Gitlab for PRs.

Monetary donations are also encouraged for open source projects.

You can either get a shirt or plant a tree, for completing 4 PRs with improvements to participating open source projects.

Also, of course if you have a project yourself you maintain, you can add “Hacktoberfest” tag to get participants to find your repo. 🙂 What are some of the projects you might consider helping?
