Ross Gammon: My March 2017 Activities

March was a busy month, so this monthly report is a little late. I worked two weekends, and I was planning my Easter holiday, so there wasn t a lot of spare time. Debian
  • Updated Dominate to the latest version and uploaded to experimental (due to the Debian Stretch release freeze).
  • Uploaded the latest version of abcmidi (also to experimental).
  • Pinged the bugs for reverse dependencies of pygoocanvas and goocanvas with a view to getting them removed from the archive during the Buster cycle.
  • Asked for help on the Ubuntu Studio developers and users mailing lists to test the coming Ubuntu Studio 17.04 release ISO, because I would be away on holiday for most of it.
Ubuntu
  • Worked on ubuntustudio-controls, reverting it back to an earlier revision that Len said was working fine. Unfortunately, when I built and installed it from my ppa, it crashed. Eventually found my mistake with the bzr reversion, fixed it and prepared an upload ready for sponsorship. Submitted a Freeze Exception bug in the hope that the Release Team would accept it even though we had missed the Final Beta.
  • Put a new power supply in an old computer that was kaput, and got it working again. Set up Ubuntu Server 16.04 on it so that I could get a bit more experience with running a server. It won t last very long, because it is a 32 bit machine, and Ubuntu will probably drop support for that architecture eventually. I used two small spare drives to set up RAID 1 & LVM (so that I can add more space to it later). I set up some Samba shares, so that my wife will be able to get at them from her Windows machine. For music streaming, I set up Emby Server. I wold be great to see this packaged for Debian. I uploaded all of my photos and music for Emby to serve around the home (and remotely as well). Set up Obnam to back up the server to an external USB stick (temporarily until I set up something remote). Set LetsEncrypt with the wonderful Certbot program.
  • Did the Release Notes for Ubuntu Studio 17.04 Final Beta. As I was in Brussels for two days, I was not able to do any ISO testing myself.
Other
  • Measured up the new model railway layout and documented it in xtrkcad.
  • Started learning Ansible some more by setting up ssh on all my machines so that I could access them with Ansible and manipulate them using a playbook.
  • Went to the Open Source Days conference just down the road in Copenhagen. Saw some good presentations. Of interest for my previous work in the Debian GIS Team, was a presentation from the Danish Municipalities on how they run projects using Open Source. I noted how their use of Proj 4 and OSGeo. I was also pleased to see a presentation from Ximin Luo on Reproducible Builds, and introduced myself briefly after his talk (during the break).
  • Started looking at creating a Django website to store and publish my One Name Study sources (indexes). Started by creating a library to list some of my recently read Journals. I will eventually need to import all the others I have listed in a cvs spreadsheet that was originally exported from the commercial (Windows only) Custodian software.
Plan status from last month & update for next month Debian For the Debian Stretch release:
  • Keep an eye on the Release Critical bugs list, and see if I can help fix any. In Progress
Generally:
  • Package all the latest upstream versions of my Debian packages, and upload them to Experimental to keep them out of the way of the Stretch release. In Progress
  • Begin working again on all the new stuff I want packaged in Debian.
Ubuntu
  • Start working on an Ubuntu Studio package tracker website so that we can keep an eye on the status of the packages we are interested in. Started
  • Start testing & bug triaging Ubuntu Studio packages. In progress
  • Test Len s work on ubuntustudio-controls Done
  • Do the Ubuntu Studio Zesty 17.04 Final Beta release. Done
  • Sort out the Blueprints for the coming Ubuntu Studio 17.10 release cycle.
Other
  • Give JMRI a good try out and look at what it would take to package it. In progress
  • Also look at OpenPLC for simulating the relay logic of real railway interlockings (i.e. a little bit of the day job at home involving free software fun!). In progress

Ross Gammon: February 2017 My Free Software activities summary

When I sat down to write this blog, I thought I hadn t got much done in February. But as it took me quite a while to write up, there must have actually been a little bit of progress. With my wife starting a new job, there have been some adjustments in family life, and I have struggled just to keep up with all the Debian and Ubuntu emails. Anyway .. Debian Ubuntu
  • Tested Ubuntu Studio 16.02.2 point release, marked as ready, and updated the Release Notes.
  • Started updating my previous Gramps backport in Ubuntu to Gramps 4.2.5. The package builds fine, and I have tested that it installs and works. I just need to update the bug.
  • Prepared updates to the ubuntustudio-default-settings & ubuntustudio-meta packages. There were some deferred changes from before Yakkety was released, including moving the final bit of configuration left in the ubuntustudio-lightdm-theme package to ubuntustudio-default-settings. Jeremy Bicha sponsored the uploads after suggesting moving away from some transitional ttf font packages in ubuntustudio-meta.
  • Tested the Ubuntu Studio 17.04 First Beta release, marked as ready, and prepared the Release Notes.
  • Upgraded my music studio Ubuntu Studio computer to Yakkety 16.1o.
  • Got accepted as an Ubuntu Contributing Developer by the Developer Membership Board.
Other
  • After a merge of my Family Tree with the Family Tree of my wife in Gramps a long way back, I finally started working through the database merging duplicates and correcting import errors.
  • Worked some more on the model railway, connecting up the other end of the tunnel section with the rest of the railway.
Plan status from last month & update for next month Debian For the Debian Stretch release:
  • Keep an eye on the Release Critical bugs list, and see if I can help fix any. In Progress
Generally:
  • Finish the Gramps 5.2.5 backport for Jessie. Done
  • Package all the latest upstream versions of my Debian packages, and upload them to Experimental to keep them out of the way of the Stretch release.
  • Begin working again on all the new stuff I want packaged in Debian.
Ubuntu
  • Finish the ubuntustudio-lightdm-theme, ubuntustudio-default-settings transition including an update to the ubuntustudio-meta packages. Done
  • Reapply to become a Contributing Developer. Done
  • Start working on an Ubuntu Studio package tracker website so that we can keep an eye on the status of the packages we are interested in. Started
  • Start testing & bug triaging Ubuntu Studio packages. In progress

Ross Gammon: My Monthly Update for January 2017

It has been a quiet start to the year due to work keeping me very busy. Most of my spare time (when not sitting shattered on the sofa) was spent resurrecting my old website from backups. My son had plenty of visitors coming to visit as well, which prompted me to restart work on my model railway in the basement. Last year I received a whole heap of track, and also a tunnel formation from a friend at work. I managed to finish the supporting structure for the tunnel, and connect one end of it to the existing track layout. The next step (which will be a bit harder) is to connect the other end of the tunnel into the existing layout. The basement is one of the favourite things for me to keep my son and his friends occupied when there is a visit. The railway and music studio are very popular with the little guests.

Ross Gammon: Happy New Year My Free Software activities in December 2016

So that was 2016! Here s a summary of what I got up to on my computer(s) in December, a check of how I went against my plan, and the TODO list for the next month or so. With a short holiday to Oslo, Christmas holidays, Christmas parties (at work and with Alexander at school, football etc.), travelling to Brussels with work, birthdays (Alexander & Antje), I missed a lot of deadlines, and failed to reach most of my Free Software goals (including my goals for new & updated packages in Debian Stretch the soft freeze is in a couple of days). To top it all off, I lost my grandmother at the ripe old age of 93. Rest in peace Nana. I wish I could have made it to the funeral, but it is sometimes tough living on the other side of the world to your family.

Jan Wagner: Searching painting: Strawberry and Man on Pumps with Sparkling wine

We are searching a motive for a painting or a painting itself for a quite while now. This should find it's place in our living room. Unfortunately we didn't found one, which matched our both prospect and/or wasn't compatible with the rest of our living room. Yesterday we stumbled upon a motive which was quite nice, but was too small and it was neighter possible to get it in a bigger size nor to find out who was the origin painter of the picture. Now we are searching for the name of the picture and/or the painter. Any hints appreciated at 'blog - at - waja - dot - info'. A photo with higher resolution can be found here Update: Okay ... an unknown people (many thanks) hinted me, that google image search is the tool that could be very usefull. Google revealed that the painter is Inna Panasenko. P.S. Is it noticeable that I'm in vacation mode? ;)

Ritesh Raj Sarraf: Reporting bugs with Apport

So yet another bug reporting tool. :-)When I prepared Apport for Debian, I wasn't sure how it will look going forward. If you look at the current one lying in experimental, it just detects your crashes and pops up in your systray. It doesn't have the mechanism to interact with BTS.So, like the title of this post says, this is the first worthy feature for Apport in the context of Debian.Apport Detail ReportNothing special here. You would have seen a similar window before if you have installed apport. What changes with this release is, that now, when you check the Send an error report to help fix this problem, it will really file a bug report on the BTS.Here's what the emailed bug report will look like:

The first 2 lines should be enough for the BTS server to file the bug report to the correct package and against the correct version.If you paid attention in the screen shot and the email report, you will notice that the email report does not include the CoreDump section. This was knocked off intentionally as we currently might not need it. If there is a need, the data is always available on the user's apport database, and the dev/user and seek it on a need basis. But in case, if a day comes when we really want it, that too is possible. The same email report will have the CoreDump seciton with a section like the following:

Now, Is this going to be useful? Will we get flooded with bug reports?
 
Usefulness: I think this will uncover many bugs that might be getting unnoticed today. Take this example itself. This bug was detect against the leafnode package's fetchnews binary. That binary does a quiet job in the background, fetching news. I never was aware that it had been crashing. As a system-wide monitoring tool, apport was able to detect, trap and inform the user of the crash. So I think this will be useful and improve the overall quality.
Abuse/Flood: This is something I can't predict. Perhaps it will bring in challenges if people just blindly click on the Send Report button. One option can be to have the "Send Report" checkbox unchecked by default. That'll hopefully lower down the possibilities.
 
What do you think? Let me know your comments.
This change will soon be pushed to apport in experimental. Hopefully this weekend.
 
I want to wrap up this post with a Thank You note to Martin Pitt and his team who created Apport, and with such simplicity. It took me 30 lines of code to adapt it to Debian. My intent with Apport is to keep the changes to the minimum so that we can always leverage new features and fixes that Apport brings in. So, as far as I'll try, there will be no drift from its original shape.

Vincent Sanders: NetSurf Developer Workshop

NetSurf DevelopersOver the weekend we held the NetSurf developer workshop. The event was kindly hosted by Collabora at their Cambridge offices. The provided facilities were agreed to be excellent and contributed to the success of the event.

Five developers managed to attend from around the UK John-Mark Bell, Vincent Sanders, Michael Drake, Daniel Silverstone and Rob Kendrick. In addition James Shaw, one of the project founders, made a special appearance on Saturday.

Starting from Friday afternoon we each put in over 25 hours of actual useful work and made almost 170 commits changing over 350 files, added 10,000 new lines of code and altered another 18,000.

The main aim of the event was to make the transition from using libxml2 to our own libdom library for the browser DOM tree. This was done to improve the browsers performance and size when manipulating the DOM but also gives us the ability to extend the browsers features to include dynamic rendering and Javascript

We also took the opportunity to discuss and plan other issues including:
  • User interface message handling and translation.
  • User preference handling.
  • Toolchain support.
  • Disc caching.
  • Javascript binding
  • Electronic book content handler.
Rob tackled the first parts of the messages conversion from numerous separate files into a single easy to handle file which will in future allow for easier translation and reduce message proliferation.

We made decisions on the ongoing rework of user preference handling which will be implemented in future.

The decision on the toolchain was slightly changed to be that any core or library code (non frontend/toolkit specific parts) are required to conform to the C99 standard. Frontends are permitted to recommend and use whatever tools their maintainer selects but they cannot enforce those restrictions on core code. This issue is principly because the BeOS maintainer is compiling NetSurf with g++ 2.95 which is missing several important language features we wish to use.

Developers at workThe recurring issue of disc caching was raised again and we have come up with what we hope is a reasonably elegant solution to be implemented over the forthcoming months.

Now there is a suitable DOM to bind against, the existing Javascript engine support will be properly integrated and should result in basic script support before the 3.0 release. This support will remain a build time option so NetSurf can continue to be used on platforms where the interpreter is too resource intensive to be used.

A short discussion about the possibility of integrating a basic page based content handler for epub and mobi type documents was discussed and while the idea was well received no decisions on implementation were made.

Overall the event was a resounding success and we are left with only a small handful of regressions which appear straightforward to solve. We also have a clear set of decisions on what we need to do to improve the browser.

Michael Prokop: Open Source Projects using Jenkins

For a (german) talk I ll be giving soon I was interested in a list of open source projects which use Jenkins. Jenkins is a great open source continuous integration server. I was wondering whether such a list exists but since it doesn t exist yet I created my own and Kohsuke Kawaguchi (creator of Hudson/Jenkins) suggested to blog about it. There we go. :) Open source projects using Jenkins, though Jenkins service not accessible for the public (yet): And Cloudbees hosts some OSS projects providing Jenkins as a service. Update [2011-08-29]: thanks for all the feedback, I ve updated the list accordingly.
If you re aware of another open source project using Jenkins please leave it in the comments, I ll update the list accordingly then.

Brice Goglin: Debian X.org notes - X.org 7.4 plans - What we expect for Lenny

The release plan for Xserver 1.5 and Xorg 7.4 was discussed during the X.org Developers' Summit in Cambridge (September 10-12th). This is what we expect to ship with Lenny, so here are some details about the upcoming. Timeline As usual, there will be a 6 months release cycle. So Xorg 7.4 is expected on March 1st, 2008. There won't probably be any new Xserver release before that since some changes (already merged) require all drivers to be updated anyway. So Xserver 1.5 is expected on the same date. Since there are already some known problems in Xserver, they also plan to release Xserver 1.4.1 on November 1st. PCI Rework The master branch of Xserver already contains the long-expected pci-rework which is supposed to fix all the PCI domains and other non-trivial PCI hierarchy support (important for ia64, but also for some powerpc and sparc users). RandR People having Intel, ATI or recent Nvidia boards learnt to love the RandR 1.2 extension which provides the ability to enable/disable, resize, rotate, move outputs within a single big virtual screen. More transformations should be possible with RandR 1.3. Hopefully, there will also be some standardization regarding output names in various drivers, or at least a way to retrieve the type of each output (LVDS, DVI, VGA, TV, ...). And the server should get an abstraction object to describe GPUs, which might make the support for multiple boards easier. Input On the input side, XKB 2 and XGE should be merged, which shouldn't be really visible to end-users but should make internals much better. Then MPX (Multi-Pointer X server) might be in Xserver 1.5 too (if all semantics issues get fixed first). It would mean support for multiple independent keyboard/mouse pairs or so. See the MPX page for details. Compositing Compositing still gets a lot of attention. Several distributions are actually thinking of enabling Compiz by default. EXA (the new acceleration architecture that has been designed for compositing) got improved a lot in Xserver 1.4. Several drivers including Intel and ATI r300 already work great with EXA (no need to use XAA + XAANoOffscreenPixmaps anymore) which means Compiz works very smoothly, even when resizing windows. XAA won't be removed soon though since lots of things needs to be fixed before that. There are also several videos available online, like this one. But one big piece is still missing for compositing: directed rendering to redirected windows. So far, if you start glxgears in Compiz, you will see that the gears completely ignore wobbli-ness of windows, other windows overriding them, cube rotation, ... they keep rendering of top of everything without any effect. Getting true support for compositing such windows requires lots of work in all parts of the DRI stack. Kristian H gsberg got it to work (and we even get a great demo). See Kristian's blog for details. Upstream devs are now working on integrating all modifications nicely in upstream Xserver, drivers, DRM module, Mesa, ... Once this works, you can get GLX_EXT_texture_from_pixmap for both direct and indirect rendering, and full support for GLX 1.4 in the server (only 1.2 is supported as of now). Also, redirected windows (let's say a wobbly window on a side of Compiz' cube) should get input events correctly thanks to input transformation in Xserver 1.5 (event coordinates will be converted into the redirected window coordinate space before being passed to the client application). Kernel-related reworks Compositing improvements actually require a large rework of the memory management in the server. Basically, we need a global management for both 2D and 3D object allocations, so that you can get both to work fine without having to change config options (things like XAANoOffscreenPixmaps or FbTexPercent). All this is related to the TTM (Translation Table Maps, see these slides for details) which has been under development for a while. It requires to change the interface with the kernel DRM modules, and it won't happen before 2.6.24. The Xserver part of the work is not big, so it might still be done before 1.5 is released. Fortunately, once all this is ready, people should stop complaining about memory allocation failures, Compiz being slow because one option is not enabled by default, ... Another hot topic in the X.org/kernel area is about moving modesetting in the kernel. When you get a kernel panic, you only actually see it if not running X (or if logging kernel messages through the network). So your machine freezes, you don't know why, you have no way to know, and you just reboot. Getting panic messages on X would be much better. To do so, the kernel needs to now which mode is currently in use on the monitor and then it will render the message on the framebuffer. This require lots of work, so it will unlikely be in Xserver 1.5 though. Miscellaneous Xserver 1.5 will also contain XACE (security framework), the cleanup of the ABI (explicit _X_EXPORT required), and possibly glucose (OpenGL acceleration for X, see Zack Rusin's blog). I asked whether there was actually some work on building the GLcore server module as a part of Mesa so that building Xserver does not require the whole Mesa source anymore. People seem to agree the current situation is a real pain for distributions and we should make this change happen. But the actual work has to be done in Mesa anyway, we'll see what happens.
