Agenda
- Progress report - GUADEC 2024 (Denver, Colorado, US) on 19-24 July 2024 - No updates
- Progress report - Open Source Summit Europe (Vienna, Austria) on 16-18 September 2024 - Linux Plumbers (Vienna, Austria) on 18-20 September 2024 - No updates
- Progress report
- The submission window for contributor proposals has closed and many proposals got done only
close to the deadline, especially also of people who did not contact us before submitting.
Those not contacting us usually have poor proposals and we do not consider them. We only
select contributors with whom we have communicated before the submission, and the most
important criterium is that they work well with us there, doing assignments well, having
done vuluntary contributions, starting on their actual project early. All this raises them
in our ranking for the selection.
- At OpenPrinting we had a good amount of candidates this year. ~15 communicated with us in
the weeks before the submission window and received assignments, building and modifying
CUPS, issues...some have even contributed valuable voluntary work starting last year.
- See details in March OP News.
- Progress report
- Many of you remember the Opportunity Open Source conference in the IIT Mandi in India which
grew out of the idea that Aveek Basu and Till wanted to meet our GSoC contributors and
motivate more people to join the free software community and GSoC.
- It was a great success and therefore we want to make it annual, meaning that we are now
aiming for its second edition.
- Very first step is to find a place and a date for the event. It should be in India again, as
most of our contributors come from there.
- So we started to brainstorm now on our "Opportunity Open Source" Telegram channel and
currently the most promising candidates are the IIT Mandi, where we did it last year, and
the IIT Kanpur.
- Most of our contributors are studying or have studied in Mandi, and even with Akarshan
Kapoor, main on-site organizer last year, being on an exchange semester in Germany this
summer, there are already others jumping in.
- Shivam Mishra, GSoC contributor and mentor in previous years, is studying at the IIT Kanpur
and suggesting to run the conference there, expecting around 300-400 attendees (instead of
the 100 we had in Mandi). He says that there "has been a really active Open-Source
community". He also says that the IIT Kanpur is larger than the IIT Mandi and closer to
Delhi, and it is "among the top 5 technical institutes in India". Travel to Kanpur would
also be easier than to Mandi, especially if it gets rainy.
- For the date we are aiming for the weekend after the UbuCon Asia 2024 which takes place in
the JECRC University, Jaipur, India, on 31 August to 2 September 2024 (Saturday to Monday),
meaning that we will go somewhere inside 6-8 September 2024 (Friday to Sunday). This way
Till (and also others, including potential speakers) can attend both with one trip, and Till
can arrive in Kanpur some days earlier for preparation. Taking the weekend before UbuCon
(23-25 August 2024) would give Till the opportunity to give a talk about this Opportunity
Open Source in Jaipur and to attend aKademy 2024 in Würzburg, Germany, on 7-12 September
2024.
- So these are our ideas for now. We appreciate a lot any suggestion or help. If you want to
discuss and/contribute, please join our Telegram channel.
- See details in March OP News.
- Progress report
- At the end of 2023 Till investigated how to make a Snap of the backends of CPDB (Common
Print Dialog Backends), especially the one for CUPS and ran into several problems,
especially as we have to do with user daemons now and the frontend browses available D-Bus
services to find all installed backends. So Till started a discussion on the snapcraft.io
forum and found out that several things need to be changed on CPDB. Biswadeep Purkayastha,
who was already volunteering for doing the Snap, started doing these changes. We covered
this here in the October 2023 News and in the November 2023 News.
- Biswadeep made good progress.
- See details in March OP News.
- Progress report
- Akarshan Kapoor is continuing to work on the scanning support in PAPPL, to allow
implementing scanner drivers as Scanner Applications and the Printer Applications for
multi-function printers also covering the scanner function.
- In the GSoC 2023 Akarshan created an eSCL parser and afterwards SANE driver retro-fitting
support for pappl-retrofit.
- Currently Akarshan is working on the implementation of the scanning API functions in PAPPL
and will continue this in this year's GSoC.
- Thanks a lot, Arkashan!
- Progress report
- Thanks to the awesome work of Rudra Pratap Singh on the Ubuntu Snap automation GitHub action
and naturally also on the Snaps themselves we have now deployed Snap update automation and
Snap versioning automation on OpenPrinting's Snaps. See our detailed coverage in the January
2024 News.
- What is still missing, is to divide up our Snap GitHub repositories into 2 branches, a
development branch and a stable branch and to have the automation running on the stable
branch and the resulting packages uploaded to the "candidate" channel of the Snap Store,
controlled by a Launchpad setup, as described in the second part of Till's Snap update
automation workshop.
- Now, using the simple autobuild mechanism of the Snap Store web admin interface, the
automation simply happens on the master branch and the resulting Snaps go into the "edge"
(development/unstable) channel of the Snap Store.
- But this is good enough to observe whether the automation works correctly, and it actually
does! So no worries any more about the frequent updates of QPDF or the many drivers
contained in the Ghostscript Printer Application. They get all just updated and as long as
they build the users get up-to-date software. Also the version numbers are nice
<upstream-version>-<Package-release> numbers, like we already know from Debian and RPM
packages.
- Thanks for this amazing contribution, Rudra!
- Progress report
- We know, classic CUPS drivers are deprecated, but there are still enough people with legacy
printers needing them. And this driver will live on as part of the Ghostscript Printer
Application, so that Linux and Windows users will be able to continue to use their
printers.
- SpliX is a CUPS driver for Samsung SPL2 printers and rebranded models from Xerox, Dell,
Lexmark, and Toshiba. It was created back in 2006 by Aurelien Croc from reverse-engineering
the protocol. Aurelian worked on it continuously improving and updating it, especially also
to support new printer models, until mid-2009, shortly after the 2.0.0 release. After that
Till continued maintaining it, just applying contributed patches for fixing bugs and adding
some new printer models, no actual development. Till did this until mid-2013.
- After that, nothing changed on SpliX, and distros simply included the latest revision, r315,
of the Subversion repository at SourceForge, where SpliX was hosted.
- See details in March OP News.
