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.
www.counting-stuff.com
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)

Turns out you can communicate across containers via 63-bits of available space in a shared lock you acquire on /proc/self/ns/time that all processes have access to.
No networking required. The post has a demo of a chat app communicating across unprivileged containers.

Its funny how my desk is littered with gloves, I think there's two pairs of cloth, one woven fingerless. And I have a separate compression fingerless gloves... And the leather ones I use when I ride my escooter...
My hands just feel chilly most of the day (until I eat)

Finally polished the first (largest here) tier of pavilion facets. Hit a few spots that had pitting in the material. Grinding those out meant nudging down neighboring facets and those neighboring facets to correct the minor depth changes 🫠 also I stubbornly didn't switch back to 8k for a while

yay managed to migrate my ghost install from the CLI setup to the now-preferred (?) docker-based setup... despite having a turnkey migration script I managed to screw up a password setting in the db and didn't realize i had to delete the persistent db file 🙃 "experienced data engineer" !

So the retrofit heat vents were pointing at the walls because the installers didn't want the hot air blowing onto people, but I've finally given up and pointed a bunch of them inwards because why bother directly heating up the wall when no one is near the air stream

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

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)
