Hello, world

So. A blog.

I've been writing code for a while now and keeping notes in scattered places. Obsidian vaults, README files nobody reads, Discord messages I can't find three weeks later. At some point you either accept that your notes will live and die in random folders, or you put them somewhere they can actually be found. This is that somewhere.

What this is

stacktrace.space. The name is what it sounds like. I spend a fair amount of time reading stack traces, and I figured if I'm going to stare at them anyway, I might as well write about what I learned from them.

This isn't a tutorial blog. I'm not going to teach you React in 30 minutes or explain Docker for the fifth time. There are enough of those. What I want to do here is write down the things I actually run into. Bugs that took hours to find, tools that changed how I work, decisions I made and how they aged, stuff I built and whether I'd build it the same way again.

Who I am

I'm jl117. Software engineer, based in Zurich.

Before software I worked a skilled trade with my hands. Sheet metal, roofs, plumbing. That's not a fun fact or an icebreaker. It's the thing that shaped how I think about building stuff. Measure twice. Plan for things going wrong. Systems fail where you're not looking, not where you are. I wrote about that in more detail in another post, if you're curious.

These days I work with Dart/Flutter, Go, Python, and whatever else gets the job done. I care about clean architecture, types, and code that the next person can actually read. I run local AI models on hardware that probably shouldn't be able to, build split keyboards, and maintain a few open source projects on Codeberg.

What you'll find here

Honest posts about things I'm working on. Build logs, debugging stories, tool reviews, opinions I'll probably change later. Maybe some keyboard stuff. Maybe some AI-on-modest-hardware stuff. Whatever I'm into at the time.

What you won't find: sponsored content, SEO bait, "10 frameworks you must learn in 2026" listicles. If I recommend something it's because I used it and it worked. If I trash something it's because I used it and it didn't.

The site itself

Ghost, self-hosted on a small VPS. No tracking, no ads, no cookie banners. I don't need your cookies. There's a mailing list if you want posts in your inbox. No spam, just new posts. If you want to know exactly what data this site does and doesn't collect, there's a privacy page. Spoiler: almost nothing.

That's it

No grand launch. No "follow me on X for more content." I'm just going to write things here and see if anyone reads them. If you're here and something was useful, good. That's the whole point.

More soon.
