Quick little Forward Kinematics demonstration in Desmos. It's a way to calculate the location of an endpoint after a series of rotations are applied to connected joints. Commonly used in Robotics & in Animation Bone Rigging Systems. You can play around w/ it here: www.desmos.com/calculator/c...

3D Vector class in C++ implemented w/ Expression Templates. The root motivation behind this approach is that you can "lazily evaluate" & compose vectors expressions together, and avoid the redundant loops & memory allocations associated with typical or naive CPU based vector operand implementations.

just finished reading this book. would recommend if you have any interest in social and/or economic networks and want a light intro. a majority of the metrics & models (ex: centrality, schelling) are explained with language and images rather than math notation which is nice.

they look super pretty. the efficiency losses are unfortunate, but it'd be interesting to see if aesthetics are enough to stimulate adoption. i've always seen the small scale of solar PVs and their capacity to be distributed in urban areas as one of their boons and nice colors could help w/ that

Just watched Whiplash for the first time. Very intense film. The self-destructive manner in which success (or the pursuit of success/greatness) was portrayed --and whether that destructiveness was necessary in the end -- is probably what sticks out to me most. Good movie

Interpolating between various FEH units based on their stats & grabbing the nearest unit to each 1/10th of the line. I made this for fun a while back but decided to make the visuals slightly nicer. The graph shows the distance of each "nearest unit" to the interpolation line.

Getting used to the orcane nerfs. Here are two hydrosliding clips since I think it's a super flashy tech the character has

Finally got around to beating Freedom Planet 2 and getting the True Ending. Had a lot of fun, and gameplaywise it feels like an improvement of the first game in almost every way. Will take a break then try get a couple S-ranks & mess with some of the other characters now that i'm done w/ main game
