TIL: an exhausted #cmos #battery can cause #Linux to behave strangely after a hard #shutdown (caused by a #UPS being incorrectly turned off) - it uses the BIOS time to check the filesystem block timestamps, and as it had gone back to 2012 the OS thinks the filesystem time is in the future! (At least the hard drive on this server isn't on the way out yet which is what I had feared, but this required an emergency visit to the office as it is the main #VOIP #PBX) #sysadmin
PLA 906114 the Program Logic Array is a vital IC in the C64. They were sold unprogrammed which means that you still needed to program the Program Logic Array with an EPROM burner

I needed a simple code lock for this years #jotajoti #scout event - won’t reveal why just yet 
Everything these days revolves around microcontrollers and sure, easy to do, however I needed simplicity and 9V battery power, outside at potentially freezing temperatures and it also needs to be low cost, I plan to use at least three of them..
Came across this simple circuit, almost too simple to be true, but it does the job just fine: push the four buttons in the right order and the output is enabled. Bingo 
Not overly secure but for my purposes, it’s a perfect little vintage code lock 
How to have the nerdiest night ever: Participate in a 4-hr Dungeons & Dragons live stream (for charity!), then listen to an awesome interview with the editors of the Chicago Manual of Style. #DnD #CMoS @grammargirl
Edibuddies, if you want to see what the significant changes to the Chicago Manual of Style are in the 18th edition, go here: https://www.chicagomanualofstyle.org/help-tools/what-s-new.html #CMOS #AmEditing
The Chicago Manual of Style will tell you exactly how to style your book or manuscript. Unsure about that comma? It will explain all, in only 19 pages. First published in 1906, it was originally called the "Manual of Style: Being a Compilation of the Typographical Rules in Force at the University of Chicago Press, to Which Are Appended Specimens of Type in Use."
But you can just call it CMOS (pronounced "sea-moss").
Bluesky was full of posts about #CMOS yesterday -- for Chicago Manual of Style updates
