I gave a talk last week involving RSS Feeds and was genuinely surprised to learn that no one in the audience was using a RSS reader daily.

In general, I dislike "Am I the only one-" questions, but: who else goes through RSS feeds every day?

I started building a LLM experiment with Python, to see how development would differ from JS.

So far, Gradio and Jupyter notebooks are winning me over. Excellent tools to test features during development and I haven't found any Node equivalents yet.

Backlog.MD is easily my favorite new tool to use for my personal projects. I've tried using self-hosted services like Planka, but having all the tasks stored inside the repo as markdown files makes it so much easier to manage.

I dug up my old Samsung 360 Gear camera for an upcoming wedding. To my surprise, it still works, albeit with some custom apps. I kinda forgot how neat 360 Photography can be in just capturing an entire moment.

A sign saying Rotterdam Centraal

And back in the Netherlands. Have to give another shout-out to @cityjsconf.bsky.social for giving me a good excuse to take the train to London, explore the city for a day, and getting so inspired that I'm now sleep deprived from hacking away last night.

Hoping to do it again next year.

@thisisjofrank.bsky.social Just wanted to quickly message that I really enjoyed your talk. I've been wanting to have a code editor in a self-hosted environment and your talk gave me inspiration on the steps I should take next.

I may have missed the link, but is the slide deck available?

Immersive PWA | PICO Developer

developer.picoxr.com/document/web...

I just checked the docs. It looks like it is a Pico-only feature right now.

Is there also an option to instantly start in VR mode? I think I remember the Pico having an option for that

So the main thing I'm getting from #CityJSLondon so far, LLM-wise, is that I've been doing way too much manually, whereas I could've used LangChainJS and MCP.

Much to experiment with in the coming days.

@kentcdodds.com While it would require additional hardware, I'd wager we can do the holographic stuff with XR hardware

And off we go at London @cityjsconf.bsky.social. Had a great day walking through the city yesterday, now onto Javascript

This has been a long time coming--excited to announce that Immersive Web Emulator 2.0 (the #WebXR browser extension, not the JS runtime) preview is available NOW!

Tap into the full power of IWER + DevUI, now in the extension format you know and love. Details & link below πŸ‘‡

I'm really holding out hope that some of this can be fixed with software updates, because I genuinely believe that this headset could make me far more productive than with the Quest.

But as said, the experience itself has been very buggy. Turning it off and on again tends gives me a gray screen. Or the menu is unresponsive. And I haven't had much luck with getting Wolvic to run any of my projects.

So first impressions are, unfortunately, very buggy.

I really like the design. Just for development, it would make for an excellent headset, especially with being able to rotate the display so easily.

Have to admit that I had written this off, so was happily surprised when it arrived this morning.

Expectations aren't too high, but I wouldn't mind having a headset specifically for development.

To my complete and utter surprise, there is a VR game based on Foundation(the novels, not the TV show). It's easily one of my favorite sci-fi series, I just hadn't expected to ever see a game released about it, let alone in VR.

First impressions over the weekend were good. Very Telltale-esque.

My first little #LLM powered project.

* It retrieves the last 50 items from my RSS reader
* Next, llama-3:3B is used to create a summary of the article.
* The result is then converted to audio using piper.
* All done on self-hosted hardware.

Perfect to listen to while walking the dogs.

Cool. I was kinda afraid that I wouldn't have a Quest Quest episode to listen to while wandering with the dogs this week.

That game has been on my to-play list for some time now. I assume the episode is very spoilerrific?

Let’s build interactive @threejs.org User Interfaces 🫰

Uses react-three/handle, react-three/xr, and react-three/uikit - vanilla versions are available🍦

Works on any device inside and outside #WebXR

Compose <uikit> with <handle> to control sizes, positions, rotations (Link in 🧡)

Took me a good five years, but finally underway to FOSDEM again. Will only be able to go on Saturday, but looking forward to it.

Any chance you still have the code somewhere? Would like to see if I could cobble a backend together for self-hosting

Got to try the Vision Pro today. While I couldn't see everything properly due to not having brought my actual VR glasses, I will admit that I was impressed with what I saw. In particular with the hands.

Was delighted to see that an old cardboard app of mine worked on it without any issue. πŸ₯³
