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...

No, sorry. Also, it'll be in Danish. Happy to catch up on a call sometime soon if you want though! Then I can share some of the things we've been working on.

Hah, this is genuinely bonkers. Just now, I was adding screenshots of tldraw comp to a presentation about AI in teaching for highschool teachers. I use it as example of a Hypercard-like future where teachers may be able to make their own interactive teaching material. I should show fairies too.

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.

Thanks for the mention! The hard work has been done by @maski89.bsky.social. If you want some more details, I wrote this thread about it some weeks ago: bsky.app/profile/clem... Our goal has not been to make a 3D tldraw, but to imagine a system where you can seamlessly move between 2D and 3D.

Spatialstrates is a collaboration between Aarhus University and Bangor University with @jensemil.bsky.social, @pwsbutcher.bsky.social, @ritsosp.bsky.social, and @nelmqvist.bsky.social.

Clemens Nylandsted Klokmose @clemens.klokmose.net · 26/09/2025

Spatialstrates builds on a decade of work with Webstrates (webstrates.net), our web-based platform for malleable and collaborative software. With SpatialStrates, we now extend these ideas into the third dimension. In fact, I presented Webstrates exactly 10 years ago at UIST 2015 in Charlotte.

Clemens Nylandsted Klokmose @clemens.klokmose.net · 26/09/2025

These shared spaces can of course also be viewed and interacted with through a 2D representation.

110

Clemens Nylandsted Klokmose @clemens.klokmose.net · 26/09/2025

In practice, this means you and a colleague can work in each your own digital room, with your own tools and objects, while keeping a shared space on, say, your desk where you can drop in objects.

110

Clemens Nylandsted Klokmose @clemens.klokmose.net · 26/09/2025

Spatial transclusion allows spaces to be embedded within other spaces. If you know HTML, you can think of it partly like an iframe in space, a space inside a space, and partly like a shared Dropbox folder, where everything inside stays synchronized between those who share it.

110

Clemens Nylandsted Klokmose @clemens.klokmose.net · 26/09/2025

For example, users can interact with objects on a digital whiteboard (think of Miro). But this board is in fact a projection of objects in a 3D space, allowing the objects to be viewed and interacted with seamlessly in immersive AR or VR as well.

110

Clemens Nylandsted Klokmose @clemens.klokmose.net · 26/09/2025

To make this possible, Spatialstrates builds on two simple but powerful mechanisms: projection planes and spatial transclusion. Projection planes map between 2D and 3D, enabling collaboration across realities so to say.

Clemens Nylandsted Klokmose @clemens.klokmose.net · 26/09/2025

In Spatialstrates, users can interact collaboratively with digital content spatially whether it’s simple digital post-its, 3D objects, or interactive data visualisation pipelines as we illustrate in the paper.

Clemens Nylandsted Klokmose @clemens.klokmose.net · 26/09/2025

Spatialstrates is a web-based platform for collaborative cross-reality computing. In practice, this means software that people can use together, simultaneously, whether they are on a conventional 2D screen on a laptop or inside an immersive 3D environment using a headset.

Clemens Nylandsted Klokmose @clemens.klokmose.net · 26/09/2025

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.

Sure, I'd be happy to! If you'll be experimenting with the idea, you could find inspiration in the service worker of MyWebstrates: github.com/Webstrates/M.... SWs can't access FS, but you can ask a client to do it for the worker (see line 166 for this pattern of requesting data from a client).

You could almost replicate "browsers shipped with servers" using a service worker and the filesystem API. It would require a domain under https that would install the initial service worker and that would be the users' frontend to the 'local server' (even when offline).

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.

$A scene of a road facing away from the viewer, viewing a bay that shows Point Reyes. The road is rained over; puddles reflect the wrought iron fence and the fractal bushes, while grass is blooming to either side of the road; translucent rainbows guide the viewer's eye to the distant landscape. A sheer cliff blocks line of sight to the left.$
