Mosh (mobile shell) is a gift from the Gods(tm). Anyone with spotty internet or wireless connection has suffered the pain of a lost SSH session. Sure, one can fire up screen (or tmux as the kids are using these days), but that's an extra step and you are still using the SSH protocol.

I'm not here to tout the benefits of Mosh, you came here to open it up in your firewall.

1. Create the following file as /etc/firewalld/services/mosh.xml
2. firewall-cmd --add-service=mosh --permanent
3. firewall-cmd --reload

If you tend to have a lot of sessions (not recommended), you can increase the ports, but the default should be fine for most applications.

This is the famous escape the matrix article from the hidden wiki. Since most mirrors are down and on the hidden wiki itself, the first chaper was replaced with a bitcoin scam, I thought I repost this here. Copyright goes to the original author and I'm not stating any opinion on this text except that it may or may not be an interesting read ;)

The .txt version is taken from here (there's also an intepretation where that came from), the markdown version was converted via some regexes by, well, me.

Have fun :)

Deadsnakes python 3.9 on Ubuntu 18.04 LTS

NOTE: Recently switched back to using pyenv so I can run multiple python versions without losing my mind. It only takes a few minutes to set up, but provides the flexibility I need without making things too complicated. See my gist, Manage python versions on Linux with pyenv for more.

The deadsnakes PPA make the latest stable versions of python available on Ubuntu 18.04 LTS (3.9 is already in the official apt repo for 20.04). I now find it preferable to installing from source.

The following was tested on a Ubuntu 18.04.5 LTS desktop with python 3.6.9 as the system python version ("python3").

The latest python available from deadsnakes as of July, 2021 is 3.9.6.
