You co-created what now??? Welcome to my feed, permanently.
Can folks do me a favor?
I was on Bluesky early & it was great. Mostly. I hit the eject button in January.
I came back, many colleagues are here, but still don’t know I am.
I co-created Halt and Catch Fire. I write TV & comics.
Here’s two favorite set photos.

Just rewatched GATTACA. A masterpiece. Perfect movie. A futuristic neo-noir that still has something to say.
Also I found a draft of the script online that has a different ending than what made it to screen. Glad they didn’t go this way, would’ve really changed the feeling of that ending (spoilers)

🎉 The Amiga 1000 turns 40 on July 23rd! The Amiga 1000 was unlike anything else: 4096-color graphics, stereo sound, multitasking and custom chips that made it a true multimedia machine. Born from the vision of Jay Miner and his team, it marked the beginning of the Amiga era!

Not only does it look and run well, but he also got the background monitor screens working, which are doing advanced framebuffer tricks!

I probably should have done this many years ago, but I finally got around to adding some useful debug features to my old Shadows sample. You can now "freeze" the cascades and zoom out, and draw them to see what they look like.

If you've got Lipschitz-continuous distance fields, you can use single-point samples to do tricks that normally require interval arithmetic – like hierarchical evaluation and expression simplification!
