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 and experience preferred (super rare at this point).

My own notes from a few months back.

Background

• Survey of LLMS
• Self-attention and transformer networks

/**
    Compression using undocumented API in rdpbase.dll

    RDPCompressEx supports four algorithms : MPPC-8K, MPPC-64K, NCRUSH and XCRUSH.

    This code supports all except NCRUSH.
    The MPPC compression ratio is very similar to LZSS, so this could be quite useful for shellcode trying to evade detection.
    
    NCRUSH compression appears to work but fails for decompression.
