going through possibly corrupted photos on the NAS, came across this legend from a carefree past. it sucked by every measure, but was a workhorse in the car, at the gym, countless flights. meticulously re-uploading the whole playlist based on the next occasion. 1GB was never enough.

what essential gadgets of yours rely on D and C size batteries?
looks like i hoarded the batteries (uhm, quite a bit) but so far i found 0 things requiring C batteries. a single 8 years old emergency lantern using D batteries; but past me already replaced them with 3xAA-to-D mags.

took me 2 days to get over the dread of writing all the yaml for this but my interior conditions nerd dash is complete.

moderation lists are cool. but you know what, i need one with the people who skip the intro on bob's burgers. i just don't need that level of ignorance and impatience in my life.

it's that time of the year where i put on a full body suit, go into the crawl space and install upgraded electronics to directly control our heat pump air handlers.

i self host a few things. love all of them. but lately the one that sparks most joy is a simple rss reader. a decade ago i was wrong to assume feeds were in a death spiral after the demise of google reader, and then rise of twitter as a notification outlet.

is there a good syncthing alternative? its android app—which was stagnant—got discontinued*.
i need to sync a few directories between my NAS, laptop, and phone. it needs to run on android & linux, not require intermediary cloud storage, and be open source.

@b0rk.jvns.ca saw the latest TIL re: sqlite backups and tangentially, healthchecks.io. i'm a fan of healthchecks, especially the ability to send start pings and capture the stdout/stderr as well. a few years ago i wrote github.com/bdd/runitor to make all this easier. maybe you'll find it useful too.

if had a penny for every time i had to point out "instead of X you just need a keyed hash", i would be a pennyaire.

RWC 2024 was a blast.
Don't wanna take the talk quality for granted, but RWC is competitive and I somewhat expected it. The highlight for me was meeting my internet friends in cryptography. Turns out they are even cooler in person. Kind folks with broad interests. I can't wait to meet them again.
