GEF extension to handle tagged and compressed pointers in v8 better (WIP)
"""
To use the extension, place the file somewhere and add
`source /path/to/extension`
in your ~/.gdbinit file
Use just as you would with `dereference` (https://gef.readthedocs.io/en/master/commands/dereference/)
but s/deref/veref/g
Many missing features because I quickly whipped this up to solve a challenge.
1) Doesn't check for v8 version (Older versions don't use compressed pointers)

Enabling enhanced session in Hyper-V for Ubuntu 20: This works for me, although it seems that Hyper-V quick create now supports enhanced session by default. #ubuntu #hyperv

Setup Hyper-V enhanced session for Ubuntu 20

I couldn't find instructions that were 100% complete, so I put this together.

These instructions worked fine for me. Follow each step carefully.

Download Ubuntu 20 desktop

DO NOT create the VM by choosing Quick Create in Hyper-V Manager. Follow these instructions exactly.

1. I cloned the repo
git clone https://github.com/Blealtan/RWKV-LM-LoRA
2. I download 7B Instruct
wget https://huggingface.co/BlinkDL/rwkv-4-pile-7b/resolve/main/RWKV-4-Pile-7B-Instruct-test2-20230209.pth

I figured out how to enable USB device mode on my XPS 13 (9350) 🎉
Though for some ungodly reason, it uses the right-side full USB port. So a crossover cable is required.

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.
