A couple of weeks ago, I read the Zig Guide by Karl Seguin and followed all the exercises. I felt comfortable enough with it, so I decided to build a small RAG application using Ollama API and Redis as storage for embeddings.
Here are my first impressions of Zig from the perspective of someone who has spent 90%+ of their coding career with C# and JavaScript/TypeScript:
- The dependency ecosystem is very young.
- Breaking changes between the language versions make the point above even worse.
- C interop is great.
- Explicit memory management feels conceptually simpler than Rust's ownership system.
- When you do run into a memory leak, the testing allocator is really helpful for debugging.
- The testing system itself is quite clear.
- Still a bit lost with the arena allocator (never encountered it before).
- The meta programming approach is interesting, the basic usage seems very clear.
- Error handling is quite unusual: functions return error unions instead of throwing exceptions.

I spent some time this weekend experimenting with Huginn. It's running on my laptop in Docker, with a MySQL DB stored in a mounted folder.
As I add this blog entry, the RSS feed updates, triggering a Huginn RSS Agent to generate an event. That event is then picked up by an HTTP Post Agent, which sends a status update to Mastodon.

LLMs are affecting the tech interview process. Thoughts on how we can address this: AI Killed The Tech Interview. Now What? TL;DR: allow AI assistants, extend the interview to 2 hours mixing architecture and coding, and have the candidate build an application with a large enough scope.

Browsers are shifting towards “double-keyed caching”, where cached data is separated based on both the resource URL and the top-level site. This aims to enhance privacy, but this post also explores its potential impact on performance and provides practical strategies to mitigate those effects.
