Agenda
- Progress report
- Many of you know that a complete CUPS printing stack (CUPS, cups-filters, Ghostscript, QPDF,
cups-browsed, ...) is available as a Snap in the Snap Store, the CUPS Snap, an immutable
system component for a wide range of Linux distributions, the latest and greatest right from
upstream, from OpenPrinting.
- And this Snap will be used in the immutable all-Snap distro Ubuntu Core Desktop, and will
also, later on, be used in standard Ubuntu.
- But Snap made it also into Ubuntu Touch, the smartphone operating system which Canonical has
discontinued and which was continued by the community. Alfred E. Neumayer (beidl,
fredldotme, Codemaster Freders) from UBPorts not only succeeded to make Snap in general
on Ubuntu Touch but also succeeded to make the CUPS Snap work and this way introduce print
functionality to the system.
- Till learned about this when Till met Rudra Saraswat on the FOSDEM 2024. Rudra is not only
leading the Ubuntu Unity and BlendOS projects but is also contributing to UBPorts, and so
Rudra took Till to the booth of UBPorts where Alfred proudly told me that he made the CUPS
Snap working.
- Till searched for more information and found the thread in the Snapcraft. Till also found
the Ubuntu Touch Q&A episode 131, where, according to the summary, in answer to a user
question about the state of printing Alfred said in the live-streamed Q&A session that he
has gotten the CUPS Snap working.
- The recording of the session is available on YouTube and the relevant part is at 45:30 min
-> 48:45 min. Here Alfred explained how he did it but also shouted out the people who made
the CUPS Snap possible.
- Now let us hope that the CUPS Snap will actually get the official printing stack of Ubuntu
Touch.
- See details in February OP News.
- Progress report
- FOSDEM 2024 (Brussels, Belgium) on 3-4 February 2024
- FOSDEM was a great experience. FOSDEM has grown a lot compared to the early 2000s, now
having 32 rooms in 10 different buildings versus the plenary room plus some rooms in
another building back in 2002. So it was often not easy to find the desired building,
room, or booth on the conference.
- Till made a mistake in his previous news posts. Till had actually given a talk at a FOSDEM
already before, in 2002! It was about Till's first one-and-a-half years of printing work at
MandrakeSoft. Back then, Till compared different printing systems, like LPD, LPRng, CUPS,
PDQ, PPR. Especially Till described what was better in CUPS and also talked about Foomatic,
printer drivers, the printing working group at freestandards.org, etc.
- And now, 22 more years have passed and a lot has changed, which Till reflected in his
second FOSDEM talk about printing: OpenPrinting - We make printing just work!
- The talk took place in the second room of the Main Track, in the ~800-seat "La Fontaine"
lecture hall in the K building, the building where also most of the booths were located.
- And people were interested. Till had the last 8 minutes for Q&A (starting at 40:50 min) and
got 3 questions: about restrictions against unauthorized printing in a school network; about
scanning standards; and also about why Microsocft did not use CUPS/OpenPrinting for Windows.
- Till's second talk, Desktop Linux, as easy as a smartphone! Just in a Snap!, in the
Distributions Track, was successful.
- Till did not have time left for Q&A right after the talk in the room. But afterwards some
of the attendees went with Till and Philipp Kewisch to ask some questions on the hallway and
Till showed them Ubuntu Core Desktop running in a virtual machine on his laptop.
- See details in February OP News.
- Progress report
- GUADEC 2024 (Denver, Colorado, US) on 19-24 July 2024
- In July we will have a GUADEC again! And so it is at the time to mention it here. This time
the GNOME fans and friends will meet in Denver (1 hour drive from Heather Ellsworth's home)!
- Till will be there and he has rushed in a talk submission before the (very early) deadline
of 18 February 2024. GUADEC has now extended the deadline to 24 March 2024, so Till will
perhaps submit another talk.
- The talk already submitted is a talk about Snap and Ubuntu Core Desktop, similar to the one
Till gave at FOSDEM. But now there will be a 40-min slot, and Till is aiming to leave 10
minutes for Q&A.
- Progress report
- If you have a look into Till's news posts of the 2 post-pandemic years 2022 and 2023 you
will see that Till has attended many conferences, so he had a lot of trips, sometimes also
long ones, to another continent, as for GUADEC 2022, Opportunity Open Source/DebConf 2023,
and the GSoC Mentor Summit 2023, but Till also had a short 2-hour train trip to Brno for
the Linux App Summit 2023.
- This year's Open Source Summit Europe and Linux Plumbers gets even closer for Till. They
both take place in Vienna in Austria! This is the city where Till lives.
- So you have the chance to visit this nice city, and you will meet Till there, as he will
attend both conferences. To make it even easer for you and to give you the chance to enjoy
Vienna for a longer time, the 2 conferences are in the same week and at the same venue:
Open Source Summit Europe: 16-18 September 2024 (Mon-Wed)
Linux Plumbers Conference: 18-20 September 2024 (Wed-Fri)
- Both take place in the Austria Center in Vienna, so we have one week of conferences there
and on Wednesday one can even hop between the two.
- Progress report
- The Linux Foundation was accepted as mentoring organization in the 20th GSoC! So we are
again looking for amazing contributors to do projects with us and improve the printing and
scanning experience with Linux.
- Our selection process already started some months ago and we already have some promising
candidates. If you want to participate, too, have a look at our project ideas list. Please
contact us as soon as possible and not only when Google's application time window opens
(18 March 2024 to 2 April 2024).
- Please send us your resume/CV and tell us what you like to work on, either on one of the
project ideas or you can also provide your own project idea. Also have a look what we are
doing via the introduction on the project ideas list page (there are also a lot of videos)
and the links on our About Us and News and Events pages.
- A nice side effect of having the contributors working on assignments we give them is that
we get several bugs fixed and smaller features implemented.
- Since last month Till has also added 2 new project ideas:
* Integrating C-based OpenPrinting projects in OSS-Fuzz testing
* Official OCI containers (Docker, ROCKs, podman) of CUPS and Printer Applications
- Please contact us as soon as possible if you are interested in being a GSoC contributor
for OpenPrinting on one of these projects or on your own project idea.
