The German School of Lisp (2011)
The German school of Lisp is described by Kazimir Majorinc as a Spartan movement 1 in Lisp implementation. But let me be clear, the Lisps in question are not toys like the one’s littering the Lisp landscape (including my own ).

We upgraded an old, 3PB large, Elasticsearch cluster without downtime
Back in 2018, now five years ago, we published a blog post describing our 400+ node Elasticsearch cluster.

Scaling Mastodon in the face of an exodus
TL;DR: Mastodon’s Sidekiq deferred execution jobs are the limiting factor for scaling federated traffic in a single-server or small cluster deployment. Sidekiq performance scales poorly under a single process model, and can be limited by database performance in a deployment of the default Dockerized configuration.

Block web scanners with ipset and iptables
Anybody who runs an internet-facing webserver has seen their fair share of spammy scanners in the logs. It varies server to server, but some of mine get up to 15,000 scans per day.
