Racket-embed-images-in-source-text (github.com/shriram)
Racket enables you to embed images in the document source. The moment you do, however, the file becomes a different format (WXME). In particular, this format is effectively binary, which means it doesn't work well with tools like grep, git, etc.

BC7 optimal solid-color blocks (wordpress.com)
That’s right, it’s another texture compression blog post! I’ll keep it short. By “solid-color block”, I mean a 4×4 block of pixels that all have the same color. ASTC has a dedicated encoding for these (“void-extent blocks”), BC7 does not. Therefore we have an 8-bit RGBA input color and want to figure out how to best encode that color with the encoding options we have.
