You don't need pulseaudio and pipewire at the same time because pipewire provides pulseaudio-compatible server (pipewire-pulse). Also, pipewire usually doesn't require audio group. Did you follow the official docs or other online guide?

Although I haven't used Arch for a long time, I guess https://wiki.archlinux.org/title/Kernel#Compilation and https://wiki.archlinux.org/title/Kernel/Arch_build_system will work.

Can you try true instead of True?

https://specifications.freedesktop.org/desktop-entry-spec/latest/value-types.html

Values of type boolean must either be the string true or false.

You can get 50 items at most with limit=50. Try

Please note that many users of FOSS are also developers or contributors. Who wants to report a bug or send a patch if the community is worse?

1. Gimp to batch edit pictures in a script (I know about ImageMagick but still)

It seems to exist: https://www.gimp.org/tutorials/Basic_Batch/

I think https://git.sr.ht/~leon_plickat/lswt may work.

Some applications can't display some Unicode strings like s̵t̵r̵o̵k̵e̵, so replacing Markdown element like ~strike~ with Unicode equivalent (s̵t̵r̵o̵k̵e̵ ) may not be a good idea if you want portability. I opened your post in text editors and noticed that neovim-qt drops s̵t̵r̵o̵k̵e̵'s combining characters (issue on Github) and just displays stroke instead of s̵t̵r̵o̵k̵e̵; GUI Emacs with my font settings (Noto) doesn't combine the characters and displays s-t-r-o-k-e- (as I said, this may depends on font settings).

Strong focus on privacy and security (all authentication with the Lemmy API is done through secure httpOnly cookies, user IP addresses are not leaked to external image hosts, etc)

Awesome. The current lemmy-ui sends a lot of traffic to other Lemmy instances to get pictrs-cached images, so this is huge improvement. On the other hand, on next.lemm.ee those requests seems to be gone. As feedback, I noticed this page still seems to send a request to imgur, ~~and the text is difficult to read because of the low-contrast theme.~~ (edit: fixed and now completely readable. thank you @sunaurus@lemm.ee )

Have you checked the shell command history? (e.g, history | grep spotify)

Most cases will be solved with these settings (but some applications may need additional tweeks):

1. Use ja_JP.UTF-8locale, or
2. Use ~/.config/fontconfig/fonts.conf

Our software is built on the reasonable assumption that third party servers cannot be trusted. For example, we cache and reprocess images and videos for you to view, so that the originating server cannot get your IP address, browser name, or time of access.

I hope Lemmy also implements the image/media caching in the not so distant future. Currently, Lemmy Web UI sends a lot of HTTP requests to external servers like imgur. (Github Issue)
