LLMs use a surprisingly simple mechanism to retrieve some stored knowledge
Researchers find large language models use a simple mechanism to retrieve stored knowledge when they respond to a user prompt. These mechanisms can be leveraged to see what the model knows about different subjects and possibly to correct false information it has stored.

Writing Gnome Apps with Swift
Swift is well-suited for creating user interfaces thanks to the clean syntax, static typing, and special features making code easier to write. Result builders, combined with Swift’s closure expression syntax, can significantly enhance code readability.

Finding memory leaks in Postgres C code
I spent the last week looking for a memory leak in Postgres’s WAL Sender process. I spent a few days getting more acquainted with Valgrind and gcc/clang sanitizers, but ultimately got nowhere useful with them. Finally, I stumbled on the memleak program from the bcc tools collection which led me right to the source…

Building an email-to-calendar LLM
Talk is cheap, show me the code Introduction A common problem my friends and I have is receiving actionable emails whose priorities are medium level. They do require action of some sort ($ \geq lowest\ priority$), but the action is due in the near future ($\leq highest\ priority$). I tend to skim over these emails…

Two open source projects with great architecture documentation
esbuild and Redis1 are two examples of codebases with exceptional documentation. Through their READMEs, changelogs, architecture documents, and code comments, both projects explain their design in such a way that someone new to the codebase can understand where things are, how things are done, and why they are done…

Bump Allocation: Up or Down?
Back in 2019, Nick Fitzgerald published always bump downwards, an article making the case that for bump allocators, bumping “down” (towards lower addresses) is better than bumping up. The biggest reasons for this are bumping up requires 3 branches vs 2 for bumping down and rounding down requires fewer instructions…

Why choose async/await over threads?
A common refrain is that threads can do everything that async/await can, but simpler. So why would anyone choose async/await?

Mutt on Windows Without WSL
I have this weird hobby of trying to get good unix tools to run natively on Windows. I find this is the most efficient use of my laptop's resources, and therefore the nicest experience. WSL is nice, but it takes up a lot of RAM on my system. I prefer to use MSYS2 . Getting unix tools to work correctly under MSYS2 is a…

Creating an autopilot in X-Plane using Python
Introduction Today’s post will take us in a slightly different direction than the last few. Today’s post will be about hooking up some Python code to the X-Plane flight simulator to enable development of an autopilot using PID (proportional-integral-derivative) controllers. I’ve been a fan of flight simulators for…

Fundamentals of Object Storage in Elixir
I did a livestream where I talked about Object Storage. The how and why. The Bad Old Days. And also the neat and interesting stuff just beyond the basics. I figured I'd cover that in text as well.

Array Languages: R vs. APL (2023)
I’ve been learning at least one new programming language a month through Exercism which has been really fun and interesting. I frequently say that “every language you learn teaches you something about all the others you know” and with nearly a dozen under my belt so far I’m starting to worry about the combinatorics of…

The C++ Killers (Not You, Rust)
All the “C++ killers”, even these which I wholeheartedly love and respect like Rust, Julia, and D, help you write more features with fewer bugs, but they don't much help when you need to squeeze the very last FLOPS from the hardware you rent. As such, they don’t have a competitive advantage over C++. Or, for that…
