The database race starts with such optimism. OLTP and OLAP swimming confidently in their lanes, NoSQL feeling quirky but making progress, and VectorDB just happy to be included. Fast forward to reality: a negative balance that would make your bank manager cry, deadlocks freezing everything, joins that mysteriously don't work, and indexes still building since the Carter administration. It's like watching Olympic swimmers turn into drowning toddlers as soon as production traffic hits. And yet tomorrow we'll all convince ourselves "this time will be different."

Content Hacker Scripts Based on a true story: xxx: OK, so, our build engineer has left for another company. The dude was literally living inside the terminal. You know, that type of a guy who loves Vim, creates diagrams in Dot and writes wiki-posts in Markdown... If something - anything requires more than 90 seconds of his time, he writes a script to automate that. xxx: So we're sitting here, looking through his, uhm, "legacy" xxx: You're gonna love this xxx: smack-my-bitch-up.sh - sends a text message "late at work" to his wife (apparently). Automatically picks reasons from an array of strings, randomly. Runs inside a cron-job. The job fires if there are active SSH-sessions on the server after 9pm with his login. xxX: kumar-asshole.sh - scans the inbox for emails from "Kumar" (a DBA at our clients). Looks for keywords like "help", "trouble", "sorry etc. If keywords are found - the script SSHes into the clients server and rolls back the staging database to the latest backup. Then sends a reply "no worries mate, be careful next time". xxX: hangover.sh - another cron-job that is set to specific dates. Sends automated emails like "not feeling wellgonna work from home" etc. Adds a random "reason" from another predefined array of strings. Fires if there are no interactive sessions on the server at 8:45am. xxX: (and the oscar goes to) fucking-coffee.sh - this one waits exactly 17 seconds (!), then opens a telnet session to our coffee-machine (we had no frikin idea the coffee machine is on the network, runs linux and has a TCP socket up and running) and sends something like sys brew. Turns out this thing starts brewing a mid-sized half-caf latte and waits another 24 (!) seconds before pouring it into a cup. The timing is exactly how long it takes to walk to the machine from the dudes desk. xxx: holy sht I'm keeping those
