So on here I talk about hobbies and crack snarky data jokes. But once a week I also write a very long form data science newsletter. at www.counting-stuff.com
#DataBS

Here's a thread of old posts that people liked [ugh no thread writing interface] (1/n)
Counting Stuff
A weekly newsletter about the important, mundane, parts of being a data scientist, UX researcher. With some extra fun about tech and hobbies.

O.o I didn't even realize we passed post 400....

This week on Counting Stuff, I dislike working on persona projects because they're usually started when there's a lot of -organizational level- nonsense going on. Plus they're technically nightmare fishing trips #dataBS

🤪 thanks to the cutting oil still on the stone, I can't tell much difference between the 50k grit polished facets (the lower big ones) versus the 8k prepolished smaller facets above

Got up to 8k prepolish over the weekend. First time trying to do an oval stone and am happy I got the facets to line up without too much fuss. Next is to polish on 50k grit and then somehow cut the girdle... Not sure how to do that well yet

Doing glue surgery to fix the Swarovski bear that the kid got as a gift a few years ago and inevitably managed to break

booo I wanted to get a second belomo 10x loupe and thanks to the tariffs they don't even ship to the US anymore

A friend asked me some questions about gems and that got me off my butt to unpack all my cutting gear. This time learning to cut an oval stone which is tricky because I have to place the side facets by eye, not absolute reference like a round. This is the first prepolish facet I had (8k grit)

... Damn it, I thought I had a 1/2 digital torque adapter to go with the new breaker bar I got for doing wheels but no, apparently I have a 3/8s one for doing spark plugs.. time to get another one 🫠

O.o whut, there's going to be a new lyrical nanoha anime series for 2026? @cyanoacry.bsky.social

Yikes, Japanese community for Mozilla disbands because an AI bot has been running all over the kb articles with slop MT translations, ignoring guidelines, and other things
November 6, 2025 at 12:08 PM
Ok I really want to know where did i pack my calibrated usb-c mic that I was using as an spl meter ... Of all my weirdo specialized tools, that's the one that disappeared off into a box somewhere

one thing i find interesting about our cat is watching it jump onto things... it's decently good at judging how much force to use so it always looks like it sorta hovers up onto the landing spot despite it being a 11lb cat

wow, for once nyc might have a non-shit mayor?
