Arch Linux Full-Disk Encryption Installation Guide [Encrypted Boot, UEFI, NVMe, Evil Maid]

Arch Linux Full-Disk Encryption Installation Guide

This guide provides instructions for an Arch Linux installation featuring full-disk encryption via LVM on LUKS and an encrypted boot partition (GRUB) for UEFI systems.

Following the main installation are further instructions to harden against Evil Maid attacks via UEFI Secure Boot custom key enrollment and self-signed kernel and bootloader.

Preface

You will find most of this information pulled from the Arch Wiki and other resources linked thereof.

Note: The system was installed on an NVMe SSD, substitute /dev/nvme0nX with /dev/sdX or your device as needed.

Fixing Broadcom Corporation BCM57765/57785 SDXC/MMC Card Reader
Follow the WORKAROUND:
1. Add a comand to /etc/rc.local, add the following line above "exit 0":
setpci -s 00:1c.2 0x50.B=0x41
2. Add the same comand to /etc/apm/resume.d/21aspm (which does not exist yet):
setpci -s 00:1c.2 0x50.B=0x41
3. Add the following to /etc/modprobe.d/sdhci.conf:
options sdhci debug_quirks2=4
4. Re-generate initrd:
sudo update-initramfs -u -k all
5. Reboot or reload sdhci module:

This gist contains instructions on setting up FFmpeg and Libav to use VAAPI-based hardware accelerated encoding (on supported platforms) for H.264 (and H.265 on supported hardware) video formats.

Using VAAPI's hardware accelerated video encoding on Linux with Intel's hardware on FFmpeg and libav

Hello, brethren :-)

As it turns out, the current version of FFmpeg (version 3.1 released earlier today) and libav (master branch) supports full H.264 and HEVC encode in VAAPI on supported hardware that works reliably well to be termed "production-ready".

Get the synth wave glow theme working for VS Code on Mac

Get the synth wave glow working for VS Code on Mac

These notes are pretty much the same steps as the two extensions list, it's just that I had to collate them together because neither seems to list it fully in the proper order.

  1. Install Synthwave ’84/Synthwave + Fluoromachine theme on VS Code (I used the Fluoromachine one)

  2. Install Custom CSS and JS Loader

  3. Command + Shift + P to open command palette > "Preferences: Open settings (JSON)"

Apple Bootrom Bug
This bug was also called moonshine in the beginning
Basically the following bug is present in all bootroms I have looked at:
1. When usb is started to get an image over dfu, dfu registers an interface to handle all the commands and allocates a buffer for input and output
2. if you send data to dfu the setup packet is handled by the main code which then calls out to the interface code
3. the interface code verifies that wLength is shorter than the input output buffer length and if that's the case it updates a pointer passed as an argument with a pointer to the input output buffer
4. it then returns wLength which is the length it wants to recieve into the buffer
5. the usb main code then updates a global var with the length and gets ready to recieve the data packages
6. if a data package is recieved it gets written to the input output buffer via the pointer which was passed as an argument and another global variable is used to keep track of how many bytes were recieved already
7. if all the data was recieved th
