Normcore LLM Reads

Anti-hype LLM reading list

Goals: Add links that are reasonable and good explanations of how stuff works. No hype and no vendor content if possible. Practical first-hand accounts of models in prod eagerly sought.

Linux kernel initialization, translated to bash
#!/boot/bzImage
# Linux kernel userspace initialization code, translated to bash
# (Minus floppy disk handling, because seriously, it's 2017.)
# Not 100% accurate, but gives you a good idea of how kernel init works

# Note: pretend chroot is a builtin and affects the current process
# Note: kernel actually uses major/minor device numbers instead of device name

Hardening USB Armory

Hardening the USB Armory

As a good crypto nerd, I usually use an entirely encrypted linux FS: / but also /boot using grub LUKS support. It's a good setup but it's not perfect, the BIOS and the bootloader are not protected.

I recently got a USBArmory and I wanted to apply the same (or a better) setup.

I found some useful links but no clear howto. So this is my setup.

This is a 5-minute (hahaha yeah right) demo of some things you might not have thought to do with the jupyter notebook to make it a good dev environment.

tmux all the things

$ tmux new -s demo

Make & activate a virtualenv

pyenv virtualenv 3.5.0 demo
pyenv activate demo
python --version
