I wonder if the reticle limits in chip fabrication could be expanded if you were restricted to using less dense patterning in the periphery where the focus isn’t as sharp. Or if the quality of focus is radial, could you pattern slightly more circuitry in a circular die than the.

I quickly rehashed a few of the arguments off the top of my head for the LIBBA folks a couple years ago. My half of the exchanges:.—.I argued strenuously against building a fully custom XR OS inside Meta, and I still don't think it is a good idea.The benefits that a custom OS can.

I had been meaning to comment on @Jonathan_Blow’s “Why can’t we even conceive of writing a new OS today” post. Coincidentally, I just got an email that opened with:. ———————————————.Hey John,. 2 years ago I pitched you LIBBA - a dedicated OS for smart glasses. You were.

The premise of the Ring of Fire books is the transportation of a modern West Virginia town to 17th century Europe, and I have been enjoying the alternate history quite a bit. They aren’t for everyone; the first few chapters of book 3 revolve around an industrial accident in a

Starlink announced a $5/month plan that gives unlimited usage at 500kbits/s. Modern apps and web pages would immediately back up every buffer and make for a painful experience, but it is fun to consider optimizing inside that tight box (in the 90s, 4x ISDN was high end!).

There have been a lot of crazy many-camera rigs created for the purpose of capturing full spatial video. I recall a conversation at Meta that was basically “we are going to lean in as hard as possible on classic geometric computer vision before looking at machine learning

Natural conversation includes interruptions and talking over people, which is hard for an LLM to model as a single autoregressive sequence. I’m sure you can get pretty far by creating a text sequence with movie-script like breaks mid sentence, but it seems like the real solution.

Please forgive and be patient with me, as producing content is a new thing for me. I created a Substack to assist in the readability of the op-eds. I realize the long form post on X isn't exactly the best. Here are the two op-eds I've written currently. Thank you for your time.

It was a fun exercise recently to just open up a completely blank file and write an RL agent from scratch, without looking at any of my prior code. There is a point of scale where rewriting things from scratch is a bad idea, but it is a blessing when you can!. By “from scratch” I.

Does @TheFIREorg have a position on cases like Collective Shout pressuring payment processors to pressure aggregators like Steam to remove content? Not a regulatory question, but still in the wheelhouse of expression suppression.

It is a trope that TV technobabble usually involves “reversing the frequencies” or “modulating the frequencies”, so I feel like a federation science officer when I declare “I am running the convolutions in frequency space!”.

Trista turned the formal dining room into a library for me at our new house, and I love it!. We still have separate shelving for paperbacks, magazines, and graphic novels, and a few more bookshelves in my Fortress of Solitude, but this is the most books I have ever had shelved in

You may have heard that an average human breathes out roughly 1kg of carbon dioxide a day. Gas masses are kind of abstract, and most of the mass is oxygen than you breathe in, but that is still 273 grams of carbon that your metabolism draws out of your body every day, even if

I can’t pass a bookstore without picking something up, but mainstream book publishing is dominated by what I consider “female authorial voice” (sometimes even from the remaining male authors), and my tastes are a little out of step with it. Robert E. Howard’s pulp fiction of a

While noting some compression artifacts in a water scene on TV, I started thinking— for a given set of compression parameters, what is “the most cursed macroblock”. Not the worst looking, which is a squishy perceptual metric, but the set of pixels that takes the most bits to.
