Matthieu Caneill of Debian announced Debsources. Excerpt of announcement below, for full announcement, see the debian-devel-announce mailing list archives.
We’re happy to announce that Debsources, the Web application that allows to browse and search the entire source code of all Debian releases, is now hosted on the official Debian infrastructure and available at https://sources.debian.org . You may already know this service as previously hosted at sources.debian.net . We took the move to Debian hardware as the opportunity to officially announce it here.[…]
Hmm, “EFI” does not work as a search string, and there are Linux-centric UEFI commands that only use “EFI”, not “UEFI”…
