Source package cross build quality assurance

 Helmut Grohne has created the Debian cross build quality assurance[1]
 service, which continually tests cross-build-dependency satisfiability
 and when possible, does cross-builds of source packages that produce
 architecture-specific binary packages. The packages are currently built
 on amd64 for all non-x86 release architectures. If your package has
 binary packages that are not arch:all, the Debian Package Tracker[2] will
 have a "cross" item in the links panel that links to the available
 results for the source package. You might want to visit the crossQA
 service and fix simple issues before doing uploads. Please note that some
 cross-build failures are caused by other packages such as toolchains,
 libraries and other build-dependencies. If you would like to ask
 questions, report issues, discuss the service or offer your help with the
 service, please use the debian-cross[3] mailing list or
 #debian-bootstrap[4] IRC channel.

Buster/Testing Virtual Machine image for Vagrant

 If you want to quickly spin a Buster/Testing VM in Virtualbox,
 there is now a new Vagrant Base Box for it:


 Follow the quickstart instructions from the Debian Wiki[5], replacing
 "stretch64" with "buster64", and using only three shell commands, you
 have a ready to use VM where you can login via ssh.

New wiki tag CategoryDebianSpeaker for Debian Speakers

 The Debian web team is in the process of removing the list of Debian
 Speakers[6] from the website.

 As an alternative, we have created a wiki category CategoryDebianSpeaker
 that you can use in your personal wiki page on the Debian wiki[7] to be
 listed as speaker.

 When adding the category to your personal page, please include a section
 with some information useful to people seeking speakers such as links to
 your previous talks, the languages you give talks in, the
 regions/locations you give talks in and the topics you are able to give
 talks about.

 More details about the reasoning and how the new system will work are

 Since February 2019 Debian LTS Announcements (DLAs) are now published on

 This means the procedures to release a DLA have changed, so please make
 yourself familiar with the procedure[9] if you are preparing an update to

#debian-til IRC channel

 In 2017 Jonathan Carter created[10] the #debian-til IRC channel. TIL is
 an acronym for "Today I Learned" and the channel is a place for people to
 share anything vaguely Debian related that they have learned recently or
 been reminded of recently. Some recent examples of things we learned:

 <pabs> TIL a command-line interface to Debian Code Search https://github.com/jwilk/dcs-cli
 <pabs> TIL systemd-escape for escaping the systemd unit names according to systemd's rules for escaping arbitrary strings
 <pabs> TIL debugging why new packages are installed during an upgrade: apt dist-upgrade -o Debug::pkgDepCache::Marker=1
 <pabs> TIL `GET -dS http://debian.org` to display the redirect chain of a URL (needs libwww-perl installed)
 <anarcat> TIL that UDD is ruby
 <anarcat> TIL that dselect is still maintained (!) and still kind of works (!!)
 <anarcat> TIL about the Sequoia OpenPGP packet dumper https://dump.sequoia-pgp.org/
 <anarcat> TIL that there *are* blob-free 5GHz wifi network cards, just not that support "AC" (only N is supported)
 <_jwilk> TIL cksum(1) is slower than md5sum(1). Go figure...
 <_jwilk> TIL when debugging user-mode-linux with gdb, you need to ignore SIGUSR1 and SIGSEGV(!): https://web2.clarkson.edu/class/cs644/kernel/setup/uml/gdb_uml.html#SigHanGDB
 <_jwilk> TIL how Linux parses command line params: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/admin-guide/kernel-parameters.rst?h=v5.1#n12
 <_jwilk> TIL "grep -P" supports only a single pattern. :-(
 <_jwilk> TIL Grumpy Cat has died. :(
