1080p
, .I used to swear that 1080p on big screens is more than enough, but I can’t look at it anymore. Everything is so big and blurry, I can’t stand it.

Changelog
Debian Upgrade
, .Unsurprisingly, upgrade to Debian Trixy (on server) and Debian Forky (on laptop)
went without issues. The biggest “problem” was switch from my custom-built
podman package on server to the version inculded with the distro: I forgot to
reinstall some dependencies so containers initially didn’t start and there were
problems with hostname resolution from within containers (apt install
aardvark-dns).
Yaxo Bug
, .Today, after at least 4 years of using
yaxo, when fixing MIME types for
directories, it occurred to me that having application/octet-stream for all
files (and directories) without extensions might be actually a bug of yaxo
rather than deficiency of QMimeDatabase, a Qt’s interface for MIME types.
Turns out, I understood what a local file is differently than Qt maintainers.
QMimeDatabase::mimeTypeForUrl turns on deep file inspection only for local
files, i.e. files which have a “file” scheme as per QUrl documentation.
QUrl("foo.txt") doesn’t have a “file” scheme, but QUrl("file:foo.txt") does.
The meaning of relative/absolute URLs for QUrl with absolute file paths is as
well different than my common sense, but this is another story.
Not Equal
, .It took me way too long to figure out why {"PrivateKey": "abcde"} and
{"PrivateKey", "abcde"} aren’t equal (hint: the latter one is set, not
dictionary and their string representations differ with only one character).
