@AmpBenzScientist i took a look at the RISC-V ISA docs and, "huh, everything actually makes sense. this is logical."
Excited to announce that I’ve a new CEO for X/Twitter. She will be starting in ~6 weeks!
My role will transition to being exec chair & CTO, overseeing product, software & sysops. https://twitter.com/i/web/status/1656747082571722753
i posted this little C code riddle earlier. so here's what it does:
1. flip all the bits in the input, so 0 becomes 1 and 1 becomes 0
2. bitwise-AND this with 1, whose binary representation is also 1. this will keep only the last bit of the number and set the rest to 0.
the result can thus only be 0 or 1. if you count in binary:
0 = ...000
1 = ...001
2 = ...010
3 = ...011
4 = ...100
5 = ...101
notice how the last bit keeps flipping for every number?
if the function was just x & 1, this would tell you if the number was odd. but if you flip all the bits before you mask it, it tells you if the number is even.
could also be written as !(x & 1)
I love a good pen and now you have me considering a pocket protector... burt I also accepted I am a nerd a long time ago :)

This guy is still out there releasing music and touring and that's pretty cool #EddyGrant
I just repaired an inexpensive ice maker by replacing a limit switch. The part only costs around a dollar. A soldering iron and some Rohs silver solder was all that was needed besides wire snips and a Phillips head screwdriver.
Don't be afraid to repair your own electronics and appliances. Do read up on repair and electricity.
It's a shame how much ends up in a landfill. Repairing instead of replacing is something that needs to come back.
