This work is being performed on a test system (that link is not safe for young eyes). In this post: FreeBSD 12.1 mfsBSD 12.1 The failed attempt I tried once, […]

Every time I go to burn a new image to a thumbdrive I have to remember how. This post aims to fix that so I can just look it up. Case in point: mfsBSD I have downloaded mfsbsd-12.1-RELEASE-amd64.img from https://mfsbsd.vx.sk/files/images/12/amd64/ From the same URL I’ve looked in mfsbsd-12.1-RELEASE-amd64.img.sums.txt and grabbed the md5 hash.

Last night I was working on a PostgreSQL function which would take a bunch of rows from one table and update rows in another table. This is part of the FreshPorts packages project. When I ran it from the command line, it worked as expected. When I ran it from within a script, the DELETE

This is just a placeholder for me to find this later. I was cleaning up some old snapshots. I’m not sure I should have removed those snapshots and I’m saving this here for next time I use bectl.
