What Is ChatGPT Doing … and Why Does It Work?
What Is ChatGPT Doing … and Why Does It Work? February 14, 2023 It’s Just Adding One Word at a Time That ChatGPT can automatically generate something that reads even superficially like human-written text is remarkable, and unexpected. But how does it do it? And why does it work? My purpose here is to give a rough outline of what’s going on inside ChatGPT—and then to explore why it is that it can d
A trip through the Graphics Pipeline 2011: Index
Welcome. This is the index page for a series of blog posts I’m currently writing about the D3D/OpenGL graphics pipelines as actually implemented by GPUs. A lot of this is well known among graphics programmers, and there’s tons of papers on various bits and pieces of it, but one bit I’ve been annoyed with is that while there’s both broad overviews and very detailed information on individual compone
The Laws of Reflection - The Go Programming Language
Rob Pike 6 September 2011 Introduction Reflection in computing is the ability of a program to examine its own structure, particularly through types; it’s a form of metaprogramming. It’s also a great source of confusion. In this article we attempt to clarify things by explaining how reflection works in Go. Each language’s reflection model is different (and many languages don’t support it at all), b
The Age of PageRank is Over [manifesto] | Kagi Blog
09 Nov, 2022 When Sergey Brin and Larry Page came up with the concept of PageRank in their seminal paper The Anatomy of a Large-Scale Hypertextual Web Search Engine (Sergey Brin and Lawrence Page, Stanford University, 1998) they profoundly changed the way we utilize the web. For the next 25 years, humanity counted on their algorithm to deliver relevant results for its searches. PageRank generated

Reddit - Dive into anything
/r/Confession is a place to admit your wrongdoings, acknowledge your guilt, and alleviate your conscience. I'm a senior in high school this year, and will be graduating come June. I have had all A's throughout high school except for last year when I got my first B. If it weren't for that B, I would have been valedictorian. I like to think that I deserved to be valedictorian; that I am truly the sm

Rust's Unsafe Pointer Types Need An Overhaul - Faultlore
Rust's Unsafe Pointer Types Need An Overhaul I think about unsafe pointers in Rust a lot. I literally wrote the book on unsafe Rust. And the book on pointers in Rust. And redesigned the Rust’s pointer APIs. And designed the standard library’s abstraction for unsafe heap-allocated buffers. And maintain the alternative Vec layout. I think about unsafe pointers in Rust a lot, and I absolutely hate th
