TL:DR; lost half my mail (150,000 messages, 6GB) last night. Cause uncertain, but possibly a combination of a dead CMOS battery, systemd OnCalendar daily, a (locking?) bug in syncmaildir, and generally, a system too exotic and complicated. The crash So I somehow lost half my mail: anarcat...

A recent vulnerability in GNU screen caused some people to reconsider their commitment to the venerable terminal multiplexing program. GNU screen is probably used by thousands of old sysadmins around the world to run long-standing processes and, particularly, IRC sessions, which are especially...

I'm sorry to announce that I gave up on the Fairphone series and switched to a Google Phone (Pixel 4a) running CalyxOS. Problems in fairy land My fairphone2, even if it is less than two years old, is having major problems: from time to time, the screen flickers and loses "touch"...

This is just a quick note to mention that I have updated my hardware documentation on the Librem 13v4 laptop. It has unfortunately turned into a rather lengthy (and ranty) piece about Purism. Let's just say that waiting weeks for your replacement laptop (yes, it died again) does wonders for...

I have strong doubts about the efficiency of any tracing app of the sort, and even less in the context where it is unlikely that a majority of the population will use it. There's also the problem that this app would need to work on Apple phones, or be incompatible with them, and cause...
