AI coding agents still need humans in the loop, so the bottleneck will still be human intelligence.

Cultures of Programming Exhibition tomasp.net/cultures/exh...

Some programming feels fun, other programming feels annoying. Why? Submit papers, essays, and demos to PX/26 by Jan 9 2026.programming-conference.org/home/px-2026...

Formulaic papers and mechanistic reviews have been ruining research for a long time. I'm glad AI is giving it the final blow, so we can, again, focus on we're good at: debating whether something is important or not.

Time to face the final boss: structure editing 😱

New paper with @tomasp.net. Baseline: Operation-Based Evolution and Versioning of Data alarmingdevelopment.org?p=1886

What defines a correct program? What education makes a good programmer? The answer depends on what culture of programming you subscribe to! This has been a long time in the making, but my open access book on the history of programming is available for pre-order! www.cambridge.org/core/books/c...

In the last part of my tiny systems course, we get to implement a tiny version of the world's most widely used programming language! TinyExcel: www.youtube.com/watch?v=ghRA...

Software Substrates Workshop. Submission deadline Feb 20 2026.programming-conference.org/home/substra...

I'm teaching 𝗪𝗿𝗶𝘁𝗲 𝘆𝗼𝘂𝗿 𝗼𝘄𝗻 𝘁𝗶𝗻𝘆 𝗽𝗿𝗼𝗴𝗿𝗮𝗺𝗺𝗶𝗻𝗴 𝘀𝘆𝘀𝘁𝗲𝗺(𝘀)! again. I'll be posting the videos & tasks on YouTube too. In the first lecture, I explain what's a tiny system, why write one and show plenty of demos! 🎞️ Playlist: www.youtube.com/playlist?lis... 👉 More info: d3s.mff.cuni.cz/teaching/npr...

Submitted. Now what?

Next week I’ll be at ACM UIST 2025 in Busan, South Korea, where @maski89.bsky.social will be presenting our work on Spatialstrates. In this project, we address the gap between everyday laptop-based computing and immersive experiences with augmented or virtual reality headsets.

I'm at #uist2025 presenting our new work with @jonathoda.bsky.social! 𝗗𝗲𝗻𝗶𝗰𝗲𝗸 is a computational substrate for end-user programming that makes it easy to implement programming experiences like programming by demonstration, collaborative editing and more! tomasp.net/academic/pap...

Subtext Retrospective www.subtext-lang.org/retrospectiv...

Dart & Flutter have made enormous progress. Getting to be a viable alternative to Browser Hell.

12 exciting live-programming projects will be presented at LIVE this year. It's free, online, and coming up soon! Sat 9/27: Videos premiere Sat 10/4: Q & A and discussion over Zoom Details on projects are up already at liveprog.org; more schedule & links coming soon. Hope to see ya there!

Companion (Workshop) Proceedings for ‹Programming› 2025 are now available! Co-edited with @jonathoda.bsky.social and @tomasp.net. Thanks to the awesome OASIcs publishing team for getting this over the line. drops.dagstuhl.de/entities/vol...

Reminder: LIVE Programming workshop submissions due July 21. liveprog.org

Is schema change someone else's problem? @jonathoda.bsky.social presenting our paper "Schema Evolution in Interactive Programming Systems" at @programming-conf.bsky.social Check it out: programming-journal.org/2025/9/2/

Do you want to write your own implementation of Tiny Boxer? Check out my demo from PLISS'25 & follow the step-by-step tutorial here: github.com/tpetricek/ti...

I found the perfect illustration for the motivation behind our paper on schema change in programming systems - presented by @jonathoda.bsky.social at <Programming> 25 next week: 2025.programming-conference.org/details/prog...

Can software express critical reflections on its own nature in the same way post-modern architecture does? I don't have the answers, but I wrote a long text with some early thoughts: tomasp.net/architecture/

The LIVE Programming Workshop will be held online this year. So no excuses - submit by July 21. liveprog.org

Excited to announce the official launch of our online book, WebAssembly from the Ground Up! 🎉 It's the book we wish we'd had 3 years ago. No messing with tools and frameworks. It's a hands-on guide to the core of Wasm: the instruction set and module format. Link below. 👇

Now that ruffle.rs is so good, I am starting to consider switching back to Flash for prototyping and procedural art. My 10-year old Unity games don't run at all. My 20-year old Flash games run better than ever. And the Flash APIs were *so good* for games. They put Canvas / SVG / DOM to shame.

My talk at HYTRADBOI www.hytradboi.com/2025/3b6de0f...

Got a demo of a graphical programming environment for distributed realtime process control. Mockup developed over a decade using Macromedia Director with >100K animation frames running from a stockpile of old Mac OS 9 towers. You may call it insanity, but it's the kind of holy insanity I respect.
