Next, I *think* this is the world's first domain name with #Braille characters
If I'm wrong, please let me know.
@pikesley @orangetronic define a function called ":", which when called pipes ":" into ":"

"&" to do things in the background (avoid blocking)

Time to think about #AdventOfCode! A 2-part coding puzzle every day until Xmas.
Might this be the year I get anywhere near collecting all 50 stars? ⭐️⭐️
If you're interested, have a look at some previous puzzles, pick a programming language, join in!

Large slow tables in PostgreSQL can sometimes work more quickly by being split into smaller tables. Table inheritance magic makes them appear as one table. Instead of using an index to find matching rows from the big table, the query will only search the matching tables. https://www.postgresql.org/docs/current/ddl-partitioning.html #postgres #sql

2013 screenshot of Google Maps satellite view of Russell Square. The plane appears to be low because the satellite's so high compared to both.

i'm beginning to realize that the vast majority of folks never grew up seeing a computer downloading files from a BBS.
here I go, pirating warez like a maniac from a bulletin board system in belgium. you'll notice the filenames are all CLS*.ZIP - CLaSS scene releases of various games from the 90s. They're downloading at some godforsaken speed not possible in 1995. Around 115200 KBaud.

Ektoplazm is my go-to site for interesting and weird music. Try the album Trojan.exe by Virus Installer for some uplifting psytrance.

This is one of my favourite educational images so I’m going to share it just because. #languages #world
@vancha sure you know of earlyoom, but that solved all my memory / swap freezes for years. Not that anything helps an upgrade gone bad - as I found out that time I accidentally uninstalled the window manager and wondered why things weren't were working so well…

I wrote a nano tool that tries to extract the #Fediverse accounts of your #Twitter followings: https://fedifinder.glitch.me/
It searches for the patterns @user@host.tld, user@host.tld and host.tld/@user in the screen name, description, location and URL field. It displays them to you in the correct format for easy copying as well as a CSV download that can be imported to #Mastodon.
Known issue: Mail addresses are included as false positives because people write their handle without a leading @: name@host.tld
