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!

We’re very pleased to present DashSpace, a web-first live and collaborative platform for immersive analytics using WebXR: github.com/Webstrates/D...

Here is @maski89.bsky.social ready to give the talk at #ieeevis 2025 and @pwsbutcher.bsky.social on deck for a demo.

icymi, in the Matrix State of the Union they said they didn't plan on pursuing decentralized social media, but they do hope to make it easier for those ecosystems to use Matrix so they don't have to reinvent what Matrix has already done
Screenshot of The Matrix State of the Union stram showing a powerpoint with the text: The Future - We're going to continue to laser-focus on being the best decentralized secure comms platform in the world. - That means we're not going to purse decentralized social - good luck to ATproto, ActivityPub, Nostr etc. - It means we're not going to pursue free-style decentralized data replication - good luck to Automerge, Beehive, Local-First etc. - It means we're not going to build other Matrix showcases (e.g. Thirdroom) - Instead, we are going to continue focusing everything on building a safe, global, resilient, secure communication network which can be used to build decentralized alternatives to WhatsApp, Signal, Telegram, Teams, Slack, Discord and friends. Screenshot of The Matrix State of the Union video showing a powerpoint with white background and black text that reads: In practice, this means: - Finish Hydra. - Fix client-controlled cryptographic group membership (either by MLS, DMLS, or client-side state resolution. - Improve metadata posture (Pseudo IDs, encrypted state events, maybe leveraging MLS) - Improving Trust & Safety - Ensuring that ecosystem-driven features like custom profiles, custom emoji, etc. actually land in the spec. - Figuring out how Matrix can be used by other ecosystems more effectively, to try to avoid ATproto/ActivityPub/Nostr/Beehive etc. reinventing Matrix.

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.
A split-screen figure shows a cross-reality collaborative space in Spatialstrates. The left side presents a first-person augmented reality (AR) view in a physical room, where a user interacts with floating 3D molecular structures, sticky notes, and analytics panels. A blue cursor line on a red sticky note represents a remote collaborator's position in 2D. The right side displays the same space in a 2D desktop interface, where 3D objects are flattened into a 2D layout: sticky notes and the analytics elements are having a very similar appearance compared to in 3D. The molecules have a different representation, displaying a table of atoms in the molecule instead. Black avatar icons indicate the projected position of the AR user's headset and controllers. The mouse cursor rests on the red sticky note.

I denne uge har jeg og en stor del af mine kolleger været værter for over 250 internationale kolleger på en forskningskonference i Århus, som mit forskningsmiljø afholder hvert 10. år.
Dét var sjovt. Og hårdt. Men mest hårdt i tiden op til og heldigvis hele tiden sjovt. >

Stakladen på Århus universitet, onsdag morgen og fyldt med tilhørere. På scenen står vi tre hovedarrangører og byder velkommen (jeg er til venstre i rødt). Sidste slide fra afsluttende session i går eftermiddags: vi ses i 2035!

It's amazing to have the book in my hand now, after several years of working on it with Kasper and Per Ola.

In a nutshell, it's a new textbook for introductory-level HCI courses:
✅ 10 parts, covering the whole HCI process
✅ 864 pages and 1.9 kgs
✅ Open access (!)

At Heroku, we basically destroyed a generation of folks personal projects when we deprecated various free plans. (My own software died too.) Now Glitch is making the hard decision to do the same: blog.glitch.com/post/changes...

The lesson is simple: don't build in the cloud if you want it to last.

We’ve got an important update for the Glitch community today: We’ll be ending web hosting for your apps on Glitch.

One of the first picutres to use now-routine techniques like surface shaders, the 'Road to Point Reyes' (1983) took a team of Lucasfilms engineers an entire month to render.
A scene of a road facing away from the viewer, viewing a bay that shows Point Reyes. The road is rained over; puddles reflect the wrought iron fence and the fractal bushes, while grass is blooming to either side of the road; translucent rainbows guide the viewer's eye to the distant landscape. A sheer cliff blocks line of sight to the left.

Karateka was one of the first "beat-em-up" games, with a simple near-far high-lo combat system. You also punched birds.
