Proxy for connecting to Podman rootless containers by domain name.
Makes Firefox the World's First Cloud-Native Dev Browser!
Seriously though, Podfox is a SOCKS5 proxy for accessing Podman's rootless network namespace from the host. Podfox creates a convenient virtual domain hierarchy in the proxy: a <container>.<network>.podman request gets resolved as <container>.dns.podman on <network>'s aardvark-dns server. Firefox can be configured to use it through a PAC policy or an included one-liner extension (TODO: maybe publish to AMO?).

Collection of decent Community-made GRUB themes. Contributions welcome!
There are many great community made GRUB themes to spice up your bootloader before booting into your system proper. Unfortunately, they're spread across multiple sites and it can be difficult to find good ones. As another user told me, the majority of themes on Pling (the largest host of GRUB themes currently) are fairly low effort and can be boring to trawl through. Hence, I decided to put together this page to bring attention to some decent themes I've found around the internet over time. They aren't all absolute masterpieces of course: But they've all at least had a fair amount of effort put into them, with custom backgrounds, fonts, and colours.
