Hello everyone! If you already know me, good to see you here!

If you don't know me: I'm a rendering engineer at Disney Animation working on our Hyperion Renderer. I've worked on every Disney Animation film since Zootopia. I post mostly about cool computer graphics and programming stuff.
Even though I live in LA, I'm almost never in Hollywood (because ew). But I was there for something last week, and thought it would be fun to try shooting pics using only
@halideapp.bsky.social on my iPhone 14 Pro... I think the pics turned out pretty nicely!

So my favorite lolwtf Disney Animation tech story that I've learned is that for a period in the 90s, the studio was using a Cray J90 supercomputer as a fileserver (which sounds absurd but made sense at the time due to some very specific/narrow requirements the studio had). (1/3)

One of the most insane G7s I’ve ever seen to win one of the most insane World Series I’ve ever seen, all carried on the back of Yoshinobu Yamamoto who put in the series pitching performance of a lifetime.

Man I love baseball.

I said October baseball is the best sport ever invented, but there's actually one sport that's even better:

NOVEMBER BASEBALL GAME 7 OF THE WORLD SERIES.

I wonder how hard it would be to build a completely DIY camera lens that is actually good, and by DIY I mean grind the glass, machine the housing, etc all DIY. I expect it’s hard, but where is it on a scale from rebuild a car engine hard to fab a microchip hard?

Holy smokes the bird rig Laika built for their new movie is absolutely incredible.

The wildest thing about the Halo: CE remake using UE5 isn't the UE5 part... it's that the remake will be coming to PS5. 12 year old me would never have believed that one day Halo would be on Playstation.

Okay, hear me out, crazy idea, but since Apple is already making these anyway, what if Apple put a nice machined aluminum faceplate on these and sold them as a product. It could have a cool name like "XServe" or something. Dunno, just spitballing, ya know?

So there's this startup aiming to put GPU farms in space because of cheap solar power but... how are they going to cool it? The vacuum of space is an insulator! The ISS uses huge radiators- their concept video shows a big solar grid but no radiators!

At work we have a long very detailed run book that describes how to bring up the entire studio’s infrastructure from a black start in case of a catastrophic event.

I wonder what the black start run book for AWS looks like. I wonder if it’s even possible to black start AWS.

AWS: customers should make sure to set up in multiple regions and AZs and set up appropriate failovers to build fault tolerant systems.

Also AWS: much of our control plane infrastructure is centralized in us-east-1.

So the guy that made a chess pawn that can unfold into a queen now has a followup video where he's made pawns that can unfold into rooks, bishops, and knights. What an insanely cool project, and he's got a great eye for filmmaking too!

A little known fact about AI art is that before the invention of AI art, nobody in the history of humanity had ever come up with the idea of "anime character looking at a sunset" before.

Shohei Ohtani puts in the greatest single game performance by any player in the history of baseball in order to sweep the Brewers in the NLCS and punch the Dodgers’ 5th World Series ticket in 9 years.

In 50 years I’m going to be telling my grandkids that I was alive to see this.

My baby isn’t even a toddler yet (she’s 11 months old) and she can go through a 10 oz clamshell of blueberries in a day if we don’t balance out her diet with other things, which is like 3% of her body weight. Proportionally for a 200 lb adult that’s 6 pounds of blueberries.

It’s pretty wild watching Dodgers baseball these days and realizing that there are currently between 6 to 8 numbers being worn that will never be worn by another Dodgers player ever again.

As usual, new Apple products means new Apple USDZ files of said products. The Vision Pro USDZ file has been updated with the new dual knit headstrap thing.

Unfortunately no nifty in-browser GLTF viewer this time though, unlike the iPhone 17 launch.

Someday I’m going to be telling my grandkids about Blake Snell and Yoshinobu Yamamoto in the 2025 NLCS.

I have not seen the new Tron movie, but I went back and rewatched Tron: Legacy and wow that movie has aged like a fine wine. It's from 15 years ago but still looks and sounds like a billion bucks; it looks and sounds way better than a lot of movies out today do.

As a Dodgers fan I hope the Dodgers beat the Brewers and win it all, supervillain reputation be darned. But as a general baseball fan I wouldn’t be upset at a Brewers-Mariners WS where no matter what it’ll be a team that has never won it all before finally winning it all.

Lol the Nobels can't even acknowledge women's contribution to discovery. But sure let's acknowledge The Machines.

Lol here's Elon's AI failing spectacularly. Kerkering bobbled the catch but recovered fast enough to throw, but then threw it wide to home instead of first, allowing Kim to score. Literally none of the players Grok mentioned had anything to do with this, and Grok got the reason totally wrong too.

There’s a neat new Blender plugin that does color transfer/matching for textures. Histogram matching is a helluva drug, kids.

It blows my mind that in the year of our Lord two thousand and twenty five, with computers with like 128 CPU cores and half a TB of RAM, you can still have a Nuke file with like 4 nodes and click on something and see the viewer update one scanline at a time slow enough to count.
