stdNullPtr / Why You Should Reconsider Playing League of Legends: The Risks of Kernel-Level Anti-Cheat Software.md
Last active May 3, 2024 03:05

TL;DR

When Riot Games introduces the Vanguard anti-cheat to League of Legends, you should STOP playing and you should not install the anti-cheat when you get the pop-up. Vanguard is a kernel-level anticheat and these anticheats operate at a privilege level HIGHER THAN YOUR OWN. The anti-cheat can do things that even you can't do, without asking or letting you know. It's like Riot installing a camera in every room of your house and getting a copy of every key inside.

Here is just one example of what they can do: https://www.theregister.com/2013/11/20/esea_gaming_bitcoin_fine/

Git Subtree Basics

If you hate git submodule, then you may want to give git subtree a try.

Background

When you want to use a subtree, you add the subtree to an existing repository where the subtree is a reference to another repository url and branch/tag. This add command adds all the code and files into the main repository locally; it's not just a reference to a remote repo.

When you stage and commit files for the main repo, it will add all of the remote files in the same operation. The subtree checkout will pull all the files in one pass, so there is no need to try and connect to another repo to get the portion of subtree files, because they were already included in the main repo.

Adding a subtree

Let's say you already have a git repository with at least one commit. You can add another repository into this respository like this:
