We've released a blog post describing how each UASTC mode is encoded at the bit level into a 128-bit block: https://richg42.blogspot.com/2020/01/uastc-block-format-encoding.html … This may change a little between now and when this ships, but this is the basic idea. (All of this has been validated in a working encoder.)

Added dynamic weather. Probably a challenge for twitter video compression, but here's rain with wet ground and puddles.pic.twitter.com/bA1UJ45gOH

New blog post! https://bartwronski.com/2020/02/03/separate-your-filters-svd-and-low-rank-approximation-of-image-filters/ … In this post, I explore separable convolution image filters: how can we check if a 2D image filter is separable, and how to use SVD and linear algebra to compute separable approximations to any filter represented in a numerical form.

"Rage Quitting" is acceptable if you work for a company that Rage Fires. And if you don't want your employees to Rage Quit, then you know what you shouldn't do.

The 6809 Color Computer's interpreter was ported from Microsoft's earlier non-6809 versions.

These BASIC interpreters were pretty amazing. The way the MS engineers handled upgrading the interpreters (from Color Basic, to Extended Color Basis, to Disk Basic) just by inserting more ROM's was pretty impressive.

I also studied a few other interpreters, especially paying close attention to their floating point code. If you find and understand their add/mul/div routines, you're in. I used this knowledge to write a x86 float FP emulator in the 90's which I used on some commercial projects.

I've closely studied the disassemblies of several 80's BASIC interpreters. My favorite was the commented 6809 disassembly for Microsoft's Color Basic/Extended Color Basic: http://www.colorcomputerarchive.com/coco/Documents/Books/Unravelled%20Series/color-basic-unravelled.pdf …

From the official People’s Daily account, this is an incredible time lapse of the building process for one of the hospitals. The pre-fab units they are putting down have windows that appear to match those in the video that claims to be of the inside. https://twitter.com/pdchina/status/1223093548515459072?s=21 …https://twitter.com/pdchina/status/1223093548515459072 …

This video shows the time for a Commodore 64 vs. a new MacBook Pro to boot, load and print a document: https://www.youtube.com/watch?v=nI3C9yLVsVE … The MacBook barely won.

This mode will only have around 64 bits of used bits out of 128, with the rest set to 0's. LZ will shrink it down to 64-bits/block or less.

Supporting this mode requires that we can transcode BC1 to ASTC and BC7 at very high quality (without pixel recompression).

One mode like this will allow the encoder to explicitly tradeoff quality for less compressed bits by selecting this mode. All the other modes were designed to fill up the 128-bit/block. This mode is designed to purposely allow the codec to achieve the same quality as BC1.

Been taking a few days break from coding on the new HQ universal codec, to rest up. I realized that we definitely need an additional opaque mode in there. Something that uses around the size of BC1 (64-bits/block) with similar quality. Why?

Watched Star Trek: Picard last night. I'm honestly lukewarm about it from watching just one episode. The writing seemed weak. It's only the first episode so I'm sure it'll get better. Will I subscribe to see this? No, I'll wait for it to be on Amazon Prime.
