Sometimes you must deal with a shitty vulnerability scanner for security compliance.
For SSH server, add the following line to your /etc/ssh/sshd_config (or a file under the /etc/ssh/sshd_config.d/) to remove SHA1 for HMAC:
MACs -*sha1*

latexmk has been complaining that something went wrong, but it doesn't show the exact error and the PDF looked like correctly produced. Turns out it was BibTeX producing a warning. You must individually invoke the "bibtexu" command to see the error, as latexmk clears message during retries.

The most simple and elegant error handling is "emergency stop," but when you are going to build a practical software, it's really important to "continue the job without stopping on terrible input." Not an irresponsible continue, but dodge with precision.

Does the current Google Chrome on Android max out the screen brightness and make the web page dark to reflect the configured brightness and then displays images in HDR when the browser finds HDR images? It jumpscared me the first time it occurred.

I spent porting the master's thesis .sty file distributed by my university from pLaTeX to LuaLaTeX this end of the year. It required some fiddling but successfully got the similar rendaring result to theses from the last year.
For the contents, ahhh, maybe some time...

Japanese LaTeX has a weird behavior that you'll get \textbf{\textgt{}} or \bfseries\gtfamily when you do \textbf or \bfseries (so you get a gothic shape by making a mincho shape bold) without correctly configuring fonts.
And there are A LOT of Japanese .cls files that REQUIRES this bug. WTF.

Owning an internet domain allows you to have a permanent link that won't affected by some service shutdowns or URL changes, which then you can use to say "Come see this URL I'm always there!" But its high cost and vulnerable system prevents me from getting one.

While it seems Prometheus is much more sophisticated, Grafana requires much more hassle to set up (Prometheus installation is just putting a small config). This may be a good example that the UI is the most complicated portion of software systems.

Very good news that Japanese Police is now working on actual cyber crimes rather than innocent pranks as seen in the past. They've improved from 5 years ago when many innocent engineers and web users are falsely accused.

It's bit early but here's the advent calendar article for tomorrow (24th). I visited the current status of Win32 API in High DPI support and the ways to make your Win32 app High DPI compatible while keeping the old OS support (from Win11, all the way to Win2k!).
