8 parallel workers (and Chromium processes) with a simple interactive CLI dashboard, exploring TodoMVC. It's getting really interesting...

Gotcha. The canvas example here is related: antithesishq.github.io/bombadil/bro... But ultimately it comes down defining generators with weights. Here's a meaty example of doing that with domain specific actions: github.com/owickstrom/b...

Oskar Wickström @wickstrom.tech · 09/09/2026

Hmm, depends on what "open the drawer" means but that sounds like a click too? I think the problem is rather using the default `clicks` generator, and instead having a custom generator that sets particular weights. Or only generates some clicks.

Oskar Wickström @wickstrom.tech · 09/09/2026

Nice! Btw, what's the custom actions for? Curious if we are missing native actions for anything obvious.

Oskar Wickström @wickstrom.tech · 21/08/2026

This leap is very satisfying, as I've been in this fight for many years, not having a good answer for one of the fundamental questions.

Oskar Wickström @wickstrom.tech · 21/08/2026

It should be noted that it's a small synthetic benchmark, I'll be back with more results from real-world apps. But combined with last week's bug found by Antithesis+Bombadil, I'm very optimistic about how this plays out.

Oskar Wickström @wickstrom.tech · 21/08/2026

Here, instead, we have full-system branching time, and the fuzzer uses client-side JS coverage as part of the objective function. It's all done with default properties in Bombadil, no extra config needed. It takes a few minutes to find the bug, it's all online learning, no over-time complications.

Oskar Wickström @wickstrom.tech · 21/08/2026

I had various designs where if you at least had isolation, then over time you could *maybe* get somewhere. Building up some graph or tree model of the space, balance exploration vs exploitation, etc. The catch is that the code also changes over time, which greatly complicates building useful models.

Oskar Wickström @wickstrom.tech · 21/08/2026

Blind random walks are useful and you can definitely find bugs that you hadn't otherwise, but there's so much you're missing out on.

110

Oskar Wickström @wickstrom.tech · 21/08/2026

This was always that one very uncomfortable concession when talking about browser fuzzing: the slowness and the practical impossibility of rewinding time, made it very impractical to do any sort of search through a state space.

Oskar Wickström @wickstrom.tech · 21/08/2026

Here's Bombadil finding a 1/6^10 probability bug (rolling a die 10 times and finding a particular sequence of numbers) inside Antithesis within minutes.

We have Bombadil 0.7.0! Lots of bug fixes and improvements, along with a new action template system. github.com/antithesishq...

Yes there's an open PR for it!

Really enjoyed this one on the podcast. Learned a bunch of things.

The Proportional Web Inspired by the "The Elements of Typographic Style" by Robert Bringhurst, this is an exploration of beautiful typography on the web, and a reusable stylesheet. owickstrom.github.io/the-proporti...

Right, I read about that one, didn't think of it as general enough but maybe it is

Oskar Wickström @wickstrom.tech · 09/07/2026

Not sure if there even are self hosting alternatives?

100

Oskar Wickström @wickstrom.tech · 09/07/2026

CloudFront for CDN currently. No ddos protection yet, haven't needed but probably will eventually. Was considering Cloudflare but I'm open to other things.

Oskar Wickström @wickstrom.tech · 09/07/2026

That's how I run my wife's site: NixOS, SQLite, bespoke Rust webapp for ecommerce. It's fast and cheap, and ironically it probably has better uptime than the enshittified platforms.

110

Oskar Wickström @wickstrom.tech · 09/07/2026

On bad days I'm at "damn it I'll just run my own server in the basement" and on better days I'm somewhere around a single NixOS machine on some VPS.

Oskar Wickström @wickstrom.tech · 09/07/2026

So, now GitHub Pages deploy is broken and I can't release my thing as planned. It really is time to move...

110

Oskar Wickström @wickstrom.tech · 03/07/2026

Good post and it definitely resonates.

Oskar Wickström @wickstrom.tech · 03/07/2026

I've reverted to chat-only and mostly rewrite from scratch because I do not trust myself with agents

130

Oskar Wickström @wickstrom.tech · 02/07/2026

Cool. Is this all CLI (e.g. single static render) or is any of it interactive?

000

Oskar Wickström @wickstrom.tech · 02/07/2026

If you need to test its rendering, you know where to find me

120

Oskar Wickström @wickstrom.tech · 02/07/2026

I'm a "centrist" I guess but this is just so draining. I don't know what to make of it anymore.

Oskar Wickström @wickstrom.tech · 02/07/2026

The levels of (and idolization of) learned helplessness and self-deception in agentic coding are staggering. How does one stay sane?

180

Oskar Wickström @wickstrom.tech · 26/06/2026

That's great, would love to read extended writing on it :)

010

Oskar Wickström @wickstrom.tech · 26/06/2026

Did it?! That's cool. Please share... :D

100

Oskar Wickström @wickstrom.tech · 26/06/2026

It's a very recent addition!

Nice! What's your experience? What's lacking?

100

Oskar Wickström @wickstrom.tech · 25/06/2026

Like, if a lot of apps were tested "just" with the default properties (essentially fuzzing, "doesn't crash") the total improvement would be significant.

010

Oskar Wickström @wickstrom.tech · 25/06/2026

Thanks, appreciate it! And yes, this is the dream. There's just so much improvement to be had, I find it extremely motivating.

Printscreen is so 2010s. Photos of e-ink monitor is where it's at.

work let me open source my meme library. big thank you to Antithesis for building a property testing engine called Hegel, without which i would not have put in nearly this much effort to produce something halfway decent.

Reading "The Elements of Typographic Style", I got way too inspired and went down a CSS rabbit hole trying to reproduce some of it. Everything doesn't transfer to web. (First image is my version, second is from the book.) Now I want to write something real with this stylesheet!

Bombadil playing terminal Tetris at 900+ actions per second. Can't really see what's going on (replays, menus, etc just flashing by). This is running the full spec language verifier on every frame.

Sorry for not posting for so long... I have been extremely busy working on my new project: The Enchanter (also called Modos Flow): a 300-ppi Eink portable monitor with 60Hz refresh rate and touch screen. It's fully open-source: gitlab.com/zephray/ench....
