Oh look, a book about antennas.

I will never escape trig, will I.

technical, a simple fast cosine 

hi i just made a simple thing for when you need something that looks like a cosine but doesn't have to be super accurate. it's still kind of expensive (four multiplies), but otoh it's actually pretty close to a real cosine.

this is a by-product of when i optimized a magnetic field implementation for uni, which included a cosine. i learnt how to make this fast from naoki shibata's sleef library, though the rounding trick is mine c:
you can find my (hopefully well-explained) code here: github.com/antoniusf/CRPropa3/

you could get a slightly more accurate result by tweaking the numbers a bit, but i like that they're so nice, so i'm keeping them.

also, this computes cos(2πx), instead of cos(x), meaning that it goes through a whole cycle in 1 unit instead of 2π units. this simplifies things.

round is a normal rounding function, i.e. rounds down for fractional parts < 0.5, and up for > 0.5.

cos(2πx):

reduced = x - round(x)
sq = reduced * reduced
((-64 * sq + 64) * sq - 20) * sq + 1

I finally learned how to build an automatic bamboo farm

I'm thinking we should start a hashtag for calming photos of moss.

How does #Mosstodon sound to you all? 😁 Come join us! 🌱

Here's another photo, for luck! 🍀

My boyfriend broke his glasses a couple months ago and finally has an eye exam appointment. He's already had to give up a job opportunity because he couldn't see, and he needs one soon or we may lose housing.

Before Saturday we need:
$85 eye exam
also ASAP:
~$15 Zenni glasses + S&H

I also do commissions! Please see pinned post!

why is open source genetic engineering not more popular

Hmm, thinking about switching to Enlightenment. I've been trying GNOME out for a few weeks, and I'm vibing with it, but systemd makes my boot time unbearably long (~37 seconds, only sort of kidding about it being unbearable). Thoughts?

I'm willing to bet that game console emulation on Gentoo is smooth af

two weeks before using Gentoo: yeah, I use Firefox. what's wrong with that?
two weeks of using Gentoo: wpa_supplicant is bloat
