Basic Security Setup for a Brand New Linode

Why

When you start a clean Linode, it isn't secured in the following aspects:

CUSTOM GAME ENGINES: A Small Study

A couple of weeks ago I played (and finished) A Plague Tale, a game by Asobo Studio. I was really captivated by the game, not only by the beautiful graphics but also by the story and the locations in the game. I decided to investigate a bit about the game tech and I was surprised to see it was developed with a custom engine by a relatively small studio. I know there are some companies using custom engines but it's very difficult to find a detailed market study with that kind of information curated and updated. So this article.

Nowadays lots of companies choose engines like Unreal or Unity for their games (or that's what lot of people think) because d

Enable `systemd` in WSL 2

**NOTE: If you have Windows 11 there is now an official way to do this in WSL 2, use it if possible - see MS post here (WINDOWS 11 ONLY)**

This guide will enable systemd to run as normal under WSL 2. This will enable services like microk8s, docker and many more to just work during a WSL session. Note: this was tested on Windows 10 Build 2004, running Ubuntu 20.04 LTS in WSL 2.

To enable systemd under WSL we require a tool called systemd-genie
Copy the contents of install-sg.sh to a new file /tmp/install-sg.sh:

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

In powershell (as admin)

	1) Create a branch with the tag
	git branch {tagname}-branch {tagname}
	git checkout {tagname}-branch

	2) Include the fix manually if it's just a change ....
	git add .
	git ci -m "Fix included"
	or cherry-pick the commit, whatever is easier
	git cherry-pick {num_commit}
