It was great to finally "get back to the game" after a long hiatus away from conferences. Thanks to the organizers of @vrsummit.bsky.social for the event and great talks, demos, networking, and all the hard work that went into it. See you all next year hopefully :)

This is devastating news. Her work has been instrumental to most of what I do today :( I have had the opportunity to only hear her speak once at a conference and was hoping to meet her in person some day. Not a great news to start the year.

I am currently on my way to Budapest for Emerging Technology Conference happening at MOME. I will talk about our long ongoing project studying digital twins of nature for research and well-being purposes. Excited to meet new scientists and artists and forge new connections.

While researching a topic, I found that in 95 Dan Ariely (RIP), published a paper Towards Quantifying Depth and Size Perception in Virtual Environments with William Gibson and it is eating me that I can't figure out if it is THE William Gibson or not doi.org/10.1162/pres... Somebody got a clue?

I have had my year long hiatus from coding in javascript. I missed it. But what I haven't missed is solving problems for 3 hours before finding out there is an issue with the library (and not a small one, React in this case). JS community should really slow in pushing "production ready" code.

I agree I look not only like a total dork, but also as a harbinger of things to potentially come. But watching Ghost in the Shell in a massive cinema while on a bus is eerily dream-like #virtualreality #vr #metaquest3

Nvidia releases a video about how gorgeous its graphics are thanks to DLSS, DLAA etc.

Well we finished Attack on Titan. And I have a lot of questions, but Gavin summarizes my main question about the last episode nicely #attackontitan #aot

As parents, staying up until midnight can be a challenge, knowing we'll be back up in just a few hours. But we made it to the countdown thanks to the gripping story of 'Attack on Titan, reaching the 20th episode of the final season with the fireworks and what a 'weird way to end the year' 😅

Here is a pickle. If somebody solved the issue of plastic bags being stuck and unable to open, how much human time and consequently life could be saved? Seriously considering it 🤔 #academicsky

I'm guessing that this has something to do with the fact that it became my "getting my son to sleep song", but still. I haven't touched the game for a year, but Cyberpunk soundtrack has always been GOAT #cyberpunk2077

I no longer feel that I am either a human or smart enough to figure this one out :/
