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.

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…

United States vs. Apple
Apple is being sued by the DOJ, but most of the complaints aren’t about the App Store. I think, though, Apple’s approach to the App Store is what led to this case.

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…

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…

The ü/ü Conundrum
I implemented search and filtering for entities on our product at epilot. The users were heavily using the feature, however, a unique issue surfaced: difficulties in filtering file names containing diacritical marks like umlauts (Äpfel, über, schön, etc.).

ARM64EC (and ARM64X) Explained
ARM64EC (and ARM64X) Explained Probably the most confused looks I get from other developers when I discuss Windows and ARM64 is when I used the term " ARM64EC ". They ask is the same thing as ARM64?

Hyprland Crash Course
For the past week I have been configuring hyprland and using it as my daily driver. Coming from major Desktop Environments like KDE or Gnome, this was definitely quite challanging, specially when implementing features that we take it for granted on these DEs, like screen sharing or screenshot annotating.
