I sometimes find myself in a position of needing to write some code that I’m just not sure how to write. Been there have you? Here are the steps I take when I’m stumped. No huge revelations here, just hard-earned advice.
The `unsafe` keyword is being redesigned to mark caller-facing contracts rather than just syntax. Safety obligations between callers and callees become visible and reviewable. The model is motivated by the rise of AI-assisted code generation and arrives as a preview in .NET 11.
I mentioned earlier on Twitter that my home computer downloaded a 22 GB database dump every three days as part of Instapaper’s backup method, and a lot of people expressed interest in knowing the full setup.
Zig is a general-purpose programming language and toolchain for maintaining robust , optimal , and reusable software.
Datomic and Content Addressable Techniques: An Ultimate Data Wonderland
This post complains about Git lacking eventual consistency. I have a little secret for you: Git can't be made to have eventual consistency. Everybody seems to think the problem is a technical one, of complexity vs. simplicity of implementation. They're wrong. The problem is semantics. Git follows…

The image alignment and registration pipeline takes two input images that contain the same scene from slightly different viewing angles. The picture above displays both input images side by side with the common scene (object) being the painting Las Meninas (1656) by Velázquez, currently at the Museo del Prado in…
Disclaimer: The post is more about understanding LUTs and HaldCLUTs and writing methods from scratch to apply these LUTs to an image rather than coming up with CLUTs themselves from scratch. Outlin…

INTRO A few years ago, I got the opportunity to architect and code the fire propagation system in Far Cry 2. At that time, it was a gigantic task and it scared the hell out of me. Luckily, it turned out well enough. With the upcoming Far Cry 3, several people recently asked me how
Seven years ago I started writing about my adventures with Clojure. I started using Octopress back then and was still using it until today. Octopress worked great for my blogging purposes and I'm grateful that it existed. However, in recent years I became frustrated with the experience of using it, which is probably…
I’ve spent quite a lot of time messing with x86_64 page tables, understanding address translation is not easy and when I started learning about it I felt like a lot of the material out there on how it works was hard for me to wrap my head around. So in this blog post I am going to attempt to provide a kind of “what I…

If you're interested in writing servers in Rust, Tokio is a project that should definitely be on your radar. It promises to leverage the exciting new work on futures in Rust to make it easy to build extremely efficient networked servers with natural, composable code.
Cliff Click gave a very good talk at Google last week. For your viewing enjoyment: The slides are available here . (For those who watched i...
Array and hash table are probably the most important data structures. Some programming languages such as Perl, Lua and Javascript, almost build the language core on top of the two data structures. …
For an upcoming project, I need to extract level data from the classic 1985 video game Super Mario Bros (SMB) . More precisely, I want to extract the background imagery for each stage of the game, excluding HUD elements and moving sprites, etc.
Listen in on Jane Street’s Ron Minsky as he has conversations with engineers working on everything from clock synchronization to reliable multicast, build systems to reconfigurable hardware. Get a peek at how Jane Street approaches problems, and how those ideas relate to tech more broadly.
What makes a good API for a library? Or more importantly, what makes it bad? This talk discusses the principles of what goes into user-centered design, and how best to apply those principles when writing a Python library for fellow developers.
I was honored to present a talk on Ruby concurrency at RubyConf 2024. It represents a high-level distillation of much of my writing and research over the past year. The conference itself was great, and presenting was such a fun experience. Here is the talk, titled “In-Depth Ruby Concurrency: Navigating the Ruby…
Hello everyone! I'm very pleased to announce that we've just managed to merge the optresult branch. Under this cryptic name is the bigges...
“The What and Why of Adapter based Parameter Efficient Fine Tuning: Understanding Its Purpose and Significance”
In part 2, we completed the user facing part of the compiler with semantic analysis. Now we're free to focus on the backend, generating LLVM. To do so, we'll use the llvm-hs-pure library, which embeds LLVM into a Haskell ADT, allowing us to manipulate it without having to set up any FFI.|A blog about various…
As we hit the holiday season, our Progress Report might be considered a bit late. A two month report became a three month report as we realized just how much work we had to catch up on. While the usual summer burst of activity didn't come, it seems instead everyone poured their time in throughout the autumn months!…
