Vermaden ☛ New jless(8) FreeBSD Jails List/Manage Tool
I have worked (and still work) with FreeBSD jail(8) containers for many years – mostly using Base System tools such as jls(8) or jexec(8) to manage them. They are quite OK – but then the world changed – VNET Jails were created … while tools remained the same – being practically blind when it comes to show important info about VNET Jails.
I could use very good and tested BastilleBSD framework instead – and I have used it in some places I was given to sysadmin – but there are places in which only so called plain FreeBSD Jails exist … and that fact gave enough reason for creating new jless(8) listing/managing tool.

From the simple but resource intensive SSAA, over theory dense SMAA, to using machine learning with DLAA. Same goal - vastly different approaches. We’ll take a look at how they work, before introducing a new way to look a the problem - the ✨analytical🌟 way. The perfect Anti-Aliasing exists and is simpler than you think.

University of Toronto ☛ Our Prometheus alerting problem if our central mail server isn't working
There is a story here. The short version of the story is that today we wound up with a mail loop that completely swamped our central Exim mail server, briefly running its one minute load average up to a high water mark of 3,132 before a co-worker who'd noticed the problem forcefully power cycled it. Plenty of alerts fired during the incident, but since we do all of our alert notification via email and our central email server wasn't delivering very much email (on account of that load average, among other factors), we didn't receive any.
