This tag collects solutions to computer problems by diagnostics that programmes emit. Since I'm entering error messages into search engines a lot more often than I care to admit, this is part of me giving back. And since these search engines are international, articles with this tag are generally in English.
Somewhere beneath the fan on the right edge of this image there is breakage. This post is about how to limit the damage in software until I find the leisure to dig deeper into this pile of hitech.
My machine (a Lenovo X240) has a smart card reader built in …
There is still a lot of hair on the Yak I am shaving in this little series of posts on SPARQL. All the Yaks shown in the series lived on the Valüla Mountain in Vorarlberg, Austria.

Alas, nvram-backup mumbled something about an unsupported BIOS …
I'm setting up an ancient machine – a Pentium M box with a meme 256 MB of RAM – with current Debian bullseye, and I'm impressed that that still works: this machine is almost 20 years old. Hats off to the Debian folks.
But that's not really my story. Instead, this is …
I've been a fairly happy mailman user for about 20 years, and I ran mailman installations for about a decade in the 2000s.
Over the last week or so, I've spent more time setting …
As part of my DIY mail server project, the other day I put a POP3 server on that box – solid-pop3d if you want to know –, and since that server doesn't have SSL built in, I configured stunnel to provide that, re-using a certificate I get for mail.tfiu.de's https …
