Glasgow revC1 is pretty close to done! Hopefully it won't have any bugs this time :-)pic.twitter.com/41fyaZFK2m
Incidentally, that's @FioraAeterna's hack to stop Twitter from doing JPEG compression, though I improved upon her pattern through manual trial and error. I should write a program to automatically optimize it... or maybe it can be constructed analytically?https://twitter.com/FioraAeterna/status/1077786781133631489 …
Tweaked a few pixels to make it compress even worse. Can't say I understand exactly what's going on here; I did start from a basic premise of "doing crap on the luma channel on a 1x1 grid, on the chroma channel on a 2x2 grid" but after that it was just poking random pixels.pic.twitter.com/FoB3lQR58X
What's it do?
I feel such local pride that you've called it Glasgow. 
why not just use pngquant to encode it as png-8 (which twitter doesn't compress) instead of using an eyesore pattern
What is it used for ?
Twitter may be over capacity or experiencing a momentary hiccup. Try again or visit Twitter Status for more information.
