No, it is a bespoke tool and the layout algorithm is specifically designed for control flow graphs. There is no description language or whatever.

Oh also I forgot to post my jam project here on Bluesky - here's Buongiorno, my tool for mapping out mDNS and DNS-SD services. It captures mDNS packets to show a graph of services being requested and advertised, e.g. printers, AirPlay, Handoff, and more.

The X-Ray Jam is complete! I had a great time and we have 10 lovely submissions you can look through: handmade.network/jam/x-ray-2025
We're planning a recap live show in the near future, so stay tuned for that.

Behold! A list of mDNS services in my house. (This is basically just the output of `avahi-browse`, so nothing too novel yet.)

The X-Ray Jam is underway (handmade.network/jam/x-ray-2025) and I am exploring mDNS.
First step: testing if mDNS works on my printer. It does.

I'm tackling mDNS, hopefully making a tool that maps out the state of all my network devices so I can see why devices only seem to show up like 60% of the time π

The X-Ray Jam is just a week away! If you are interested in tools that dig into software internals then you should participate or at least follow along.

This is for a WASM record/replay tool I'm building for work. It instruments arbitrary WASM modules to record specific function calls to a log, then can recreate the module state to replay them.

I have started to go down the compression rabbit hole. The compressor and decompressor are handwritten WASM.
Uncompressed: 52MB

Sometimes you spend weeks on a performance optimization to get 0.5% faster. Other times you spend a day tweaking your GC code and get 15%+ faster.

We're doing a Handmade podcast again!
Our first episode of 2025 is an interview with aolo2, a web dev turned CPU engineer, about several apps he has made from scratch: a collaborative whiteboard, a Handmade Slack alternative, and a CPU trace viewer.

A file explorer called File Pilot just released in open beta yesterday: filepilot.tech
It is so insanely fast that it makes you question how all other software is developed. The Handmade community does good work.

The point of my post was that optimizations to Memory64 will NEVER be able to fully eliminate bounds checks the same way we can for 32-bit wasm.

After working hard to get 64-bit WebAssembly released in browsers, I would now like to discourage most people from using it π

Is Memory64 actually worth using?
After many long years, the Memory64 proposal for WebAssembly has finally been released in both Firefox 134 and Chrome 133. In short, this proposal adds 64-bit pointers to WebAssembly.
