TIL the soundtrack to 1984 Dune was done mostly by Toto and now in my head I hear
"...I bless the rains down in Aaaaarrakis..."
Still amazed at this '80s rom com that starts off with a correct and mostly complete proof of the snake lemma 🤯 https://www.youtube.com/watch?v=etbcKWEKnvg
Checkmate, Yakult drinkers! #poop "Yakult is a probiotic dairy product made by fermenting a mixture of skimmed milk with a special strain of the bacterium Lactobacillus casei Shirota...The first Lactobacillus bacteria was originally isolated from human feces at Yakult Central Institute in Japan" https://en.wikipedia.org/wiki/Yakult
*chef's kiss* "...the station had been power washed for 4 hours one night, but the smell became worse...the station had not been adequately cleaned for so long, in which urine was “seeped into the ground,” and the smell was exposed from the power washing"

Easier way:
1) Wrap a cylinder around the great circle with the same tangents at every point.
2) Do the calculations on the cylinder instead (much easier)
3) Use the induced connection from R^3 to justify 2).
3) Use uniqueness of geodesics and of great circles to conclude that geodesics = great circles.
Cool way to show that great circles are sphere geodesics but other circles of latitude aren't:
1) Wrap a cylinder around the great circle with the same tangents at every point.
2) Similarly wrap a cone around the circle of latitude (that's not a great circle).
3) Do the calculations on the cylinder/cone instead (much easier)
4) Use the induced connection from R^3 to justify 3).
Today, ~20 years after I started studying Japanese, I finally had the chance to say 「これはペンです。」!🤓🇯🇵
What even are erasure codes? Find out how they work in my new blog post! (first in a series) https://www.akalin.com/intro-erasure-codes

I apologize in advance for infecting you with this earworm.
lazymastodon: any dev/tech/cool meetups in Tokyo I should look into? I'll be there in December!
The "Gerald's Game" Netflix movie is a really good adaptation of the King novel. So good, I had to turn away during ~that one part~ and even so it made me a bit ill anyway.
Imagine a Lifetime movie, but with good production value and rated R!
Today I was reminded that this existed: https://www.youtube.com/watch?v=yD3iaURppQw
someone on IRC was raging about a bad explanation of matrices and inspired me to do this #MathMemes https://mastodon.social/media/YXiGT9H2HstkqzWneTo
Tfw you realize you've been confusing David Lynch and David Fincher this whole time 😅
