    Not read this thesis fully but it covers derivation of and thinking behind the HDR color spaces ICaCb and ICtCp. Worth a look.

    Two amazing music videos. "Aleph2" plays with countable sets: "Order from Chaos" shows flatland lifeforms:

    We have been blessed with a visitation from the tea fairy. Clarity of thought can finally resume.

    CGI question: what is it about this clip that makes it feel like a model rather than full scale? How could you fix this? I believe it's in the GI distance falloff suggesting scale

    I seem to be doing a thing at revisiting "Faster Math Functions" updated with the latest ideas from FPGA and Embedded worlds. So much good stuff.

    Entropy is the amount of information you don't have about the random details of a system: what you'd need to describe those details. It takes 500 zettabytes to fully describe a gram of liquid water, but a manageable amount per molecule! (1/n)

    The digits of Pi in a single float (with the elided first digit) are quite poetic: 100 100 100 00<pause> 111 111 011 011 0x40490FDB for those following along in hex.

    Thanks for sharing! I've been meaning to learn more about compressed sensing for years. FYI here's the talk on YouTube:

    Can't recommend this book highly enough. Gentle, correct explorations of bitwise hacks with all caveats explored. Timeless gems.

    Previous jobs at large companies would have demanded a report on the initial few failures and called off any additional work in that direction, and they would have missed the breakthrough. I love this startup that's doing so many things right. 2/2

    My recent experiences with "work harder not smarter": I now know the power of "gently dicking about with math" bringing enormous advantages. Give it space, sidle up to a hard problem, build upon simple knowns, and give yourself time to explore the edges. 1/2

    The newest stuff is free breathing continuous acquisition- you let the patient breathe freely, gather data throughout, and recover an image afterwards

    The beginnings of compressive sensing and use of the L1 norm to recover signals from sparse data came from MRI scans of tiny babies. Diagnosis required we temporarily kill them for a high res scan, so how to do more with less data?
