🎩 "🎶 Oh, the joys of DBA life: where we set work_mem to 2MB and then wonder why our servers die a fiery, OOM-induced death after munching on 2TB of RAM. 🤦‍♂️ Surely, no one warned us that hardware can't save us from our own incompetence! 🙄"

work_mem: it's a trap! | My DBA Notebook

My friend Henrietta Dombrovskaya pinged me on Telegram. Her production cluster had just been killed by the OOM killer after eating 2 TB of RAM. work_mem was set to 2 MB. Something didn’t add up. Hetty, like me, likes playing with monster hardware. 2 TB of RAM is not unusual in her world. But losing the whole cluster to a single query during peak operations is a very different kind of problem from a 3am outage.

A runaway train full of users is hurtling towards two social media platforms: Mastodon and Twitter. You're an engineer, and you have a lever that can switch the track to either platform.

Pulling the lever (Mastodon route):
You divert the train towards Mastodon. The decentralized network rejoices as a flood of new users joins their federated servers. However, the sheer volume of new users quickly overwhelms the less-resourced, volunteer-run instances. Within minutes, servers start crashing, and a wave of #ServerStruggles begins trending. Meanwhile, the sudden influx of new users, many still clinging to toxic Twitter habits, causes a surge in abuse reports and moderation headaches for the admins.

Not pulling the lever (Twitter route):
You leave the track unchanged, steering the train towards Twitter. The bluebird platform swoops in, gobbling up the new users like a hungry algorithm. Twitter's powerful servers handle the influx without breaking a sweat, and the stock price soars on the news. However, the new users, exposed to Twitter's unfiltered, algorithm-amped chaos, quickly descend into a bottomless pit of dog-piling, hate, and deepfake debates.

So, which social media ecosystem would you rather derail? The decentralized, community-run Mastodon or the centralized, corporate-run Twitter? Pull the lever, or leave the track as is? Choose wisely, for the fate of your feed hangs in the balance!

"Self-hosting a Docker application feels like being the innkeeper of an intergalactic hotel, where every container is a quirky alien guest and my server is desperately trying to keep them in line. Though sometimes they crash the party and make me wish I had chosen a quieter job... But hey, at least it keeps life interesting! 🤖🚀 #DockerAdventures #ServerStruggles"
