I needed to enable Secure Boot so that I could play League of Legends with Riot’s Vanguard Anti Cheat. It seemed complex at first but was actually easier than I expected. The Arch Wiki is both helpful and confusing here, it provides a bunch of different ways to do this, but doesn’t always do a great job of differentiating them as logically separate processes.
My basic understanding of Secure Boot is that when your computer first loads up, it loads the motherboard firmware, which then boots a bootloader. I remember from my OS classes that historically, the bootloader is 512 bytes, specifically the first 512 bytes on the boot disk. The bootloader can be anything, the computer will just run it because of its location in storage, which means malicious actors could run any arbitrary code there and compromise the system. Secure boot mitigates this by only allowing cryptographically signed bootloaders to run. The process outlined here is to sign our bootloaders so that Secure Boot will allow them to run. We are doing this by using our own keys (see Assisted process with sbctl🔗), rather than using a pre-signed boot loader. Note that “firmware” here refers to the motherboard firmware, commonly referred to as “the BIOS”

General Tips
vim -p file1 file2 to open multiple files as tabs:qa to quit out of all open buffers:Ex to return to netrw (file explorer)
Terminals
:term to open a terminal in current window- Use
i to enter insert mode and type into the shell
<C-\><C-n> to return to normal mode to allow scrolling or switching windows
- I’ve remapped this to
<C-space>
Windows
<C-w> prefixes all window commands<C-w> + h,j,k,l to focus window to left, bottom, up, right, respectively<C-w>s to split current window horizontally, equivalent to :split<C-w>v to split current window vertically, equivalent to :vs
Registers
"c before a command, where c is the register to store the text- Use capital letter to append to the register, e.g.
"C
Macros
- Press
qc to start recording, where c is the register to store the macro
- Stop recording with
q
- Replay the macro with
@c
Setting Up ZNC with Docker
ZNC is an IRC bouncer, which is a program that acts as a middleman between your IRC client and any servers you connect to. This provides a number of benefits, the most notable of which is chat history while your client is closed. This guide is how I set up
I have a Raspberry Pi connected to my network that I use as a DNS server with Pi-hole🔗 and nginx-proxy🔗, as well as a host for several web-based services. Each service is a Docker container, which I manage through a single Docker Compose file. To install ZNC, I simply add a container to the Compose file.

League of Legends on Linux
LoLoL for short
Important update
With Vanguard coming to League in the near future, League on Linux is no more.
These are my notes on how I got League of Legends running on my Linux system. It runs almost flawlessly, the only issues I have are with the client, but even on Windows the client is garbage. The game itself runs even better on Linux than it does Windows.
