I think most people are aware of the Humble Bundle which have been releasing a range of cool and great games on Linux since they started up. The games though has usually tended to be distributed as a tarball and doesn’t automatically integrate itself into your Fedora system like you would like. Well thanks to the cool effort called Mumble RPMS you can now turn all those tarballs from the Humble Bundle into nice RPMS for Fedora. So a big thanks to the author of Muble RPMS for doing this work!
I have made a first test release of Transmageddon today, 0.23. It is the first release depending on GStreamer 0.11/1.0 and GTK3. It also features a little bit of GNOME Shell and Unity integration in the form of a notification message when its done transcoding and the menu has been moved into the shell. You can find the test release in the pre-release directory on linuxrising.org. Let me know if you have any issues so I can try to fix them before I make a final stable release when GStreamer 1.0 is released. Be aware that you want the GStreamer 0.11 releases from yesterday to try this release.
The above screenshot is taken on my Fedora 18 test system!
So I am looking to hire two more people to join our team. So if you ever wanted to join the worlds leading Linux company and work on making the desktop rock this is your chance.
The first position I have available at this point is for a Webkit developer. We have a lot of applications these days in the desktop relying on Webkit and we need someone in the team who can both work on making sure our webkit packages in Red Hat Enterprise Linux(RHEL) and Fedora are kept up to date, but also work with other desktop team members with application integration issues and so on. You will also have time to work upstream to help push Webkit and especially WebKitGTK+ forward.
The second position I am looking for a candidate for is working on the Evolution email client. Evolution has been with us for quite some time and thanks to the effort of the current development team a lot of important infrastructure work has been done, like a new accounts system and the soon to be finished migration to Webkit. But we want to make sure Evolution keeps progressing and have the features it needs to be the primary email client for both Fedora and RHEL users. In addition to the work on Fedora and RHEL this job will include working on upstream Evolution and upstream libraries used by Evolution, such as WebKit, OpenChange and Kolab.
Also beyond these jobs Red Hat is looking for more people with Python development experience to join our 500 strong team here in Brno, Czech Republic, so even if the two jobs above is not your cup of tea, but you do have Python experience and joining Red Hat in Brno is something that could be of interest to you, please get in touch and I well put you in contact with the right people here. We are looking both of all levels for these python jobs, so both people fresh of out Uni or with many years of experience should get in touch. Be aware that these python jobs are not in the Desktop team though, but in some of our other cool teams here.
So if any of the above is of interest to you please contact me on cschalle(at)redhat(dot)com.
So thanks to Ubicast we now have the recordings of this years talks available online. A couple of talks got lost due to technical issues, but most of them are there and I hope you enjoy them. We are collecting the slides at the GStreamer Conference 2012 wiki page, but be aware that we are having some issues with the wiki this morning.
Sometimes we get questions about if GStreamer can scale to handle really complex pipelines. Well thanks to Kipp Cannon and his talk at this years GStreamer Conference we know have the answer.
They are part of a research project called LIGO which is doing researching gravitaional waves, which can be described as ripples in the fabric of space-time. Kipp is part of the LIGO Data Analysis Software Working Group which has develop a what the call gstlal.
P.S. You might want to download and view the following with an image viewer application as the browser struggles to render it in any detail
Anyway, to make a long story short, their pipeline looks something like this image (created with the built in graph dump functionality of GStreamer using graphviz).
If you ever seen a bigger pipeline please let me know Also it should alleviate any concerns you might have about GStreamers scalability.
So Miguael de Icaza posted a blog with his opinion about why Desktop Linux has not become a huge success. The core of his argument seems to be that the lack of ABI stability was the main reason we didn’t get a significant market share in the desktop market. Personally I think this argument doesn’t hold water at all and the comparison with MacOS X a bit random.
So I think there are a lot of contributing factors to our struggle in the desktop market like:
- We are trying to compete with a near monopoly (Windows)
- Companies tend to depend on a myriad of applications to run their business, and just a couple of them not running under Linux
would be enough to derail a transition to Linux desktops
- We were competing not only with other operating systems, but with a Office productivity application monopoly
- We are trying to compete by supporting an unlimited range of hardware options
- We divided our efforts into multiple competing APIs (GNOME vs KDE)
- There was never a clear method of distributing software on Linux outside the distro specific package system.
- Many of our underlaying systems were a bit immature
- Software patents on multimedia codecs made it hard to create a good out of the box experience for multimedia
- Competing with free applications is never a tempting proposition for 3rd party vendors
- We never reached a critical mass where porting to desktop Linux tended to make sense
- An impression was created that Linux users would not pay for any software
- The different update cycles of the distributions made it hard to know when a new API would be available ‘everywhere’
- Success in other areas drained resources away from the desktop
The Apple Myth
So how did Apple succeed? Well first of all the question needs to be asked if they have succeeded? When Steve Jobs came back to Apple I think their global market share for personal computers was down to just below 5% if my memory serves me correct. According to Wikipedia (not the best proof of anything, but lets assume they are in the ballpark) their marketshare is now about 7.5%. So in other words on the back of being the media darling and record breaking products such as the iPod, iPhone and iPad, they have managed to increase their market share with 2.5% in the PC market. I think that speaks volumes about the challenges posted by the first two items in my list above. Another thing that is both an advantage for Apple and a disadvantage at the same time is that they got their own hardware. In the advantage collumn that means that their developers had a very limited set of hardware configurations to support and they could ensure MacOS X ran well on that configuration. We on the other hand have been struggling with trying to support basically any random configuration out there, which means ensuring a problem free experience for everyone is next to impossible. Of course I think only supporting your own hardware also does sometimes makes things harder for Apple, because if a company was considering switching to MacOS X they would have to throw away all their existing hardware, which I am sure makes a lot of companies think twice if contemplating switching.
Apple were also able to build on their old market share when launching MacOS X, which means they have had a profitable ecosystem all the way. So for instance porting games has provided enough income to support companies in keep doing so. While for Linux it has often been a proposition of trying to build a market when considering porting to Linux.
So I could go intro great detail for each of my bullet points, but I think they are quite self explanatory. But my general point is that I when I ask myself if I think our market share would be significantly higher if our ABI stability had been even better, the answer is no. Not that I am saying I think it has had no impact at all, I am sure examples exist of ABI breakage or distro fragmentation having caused 3rd party software developers to shy away, but I don’t really believe Linux would have had for instance a 10% marketshare today if only our ABI stability had been better over the last 10 years. But maybe it would have added another 0.2% or something in that range.
But as I said in an earlier blog post, I am not negative about the future of Linux and open source on the desktop. I just think it is a lot slower slog to get there than we hoped for, and I do honestly feel that we have a much more compelling product to offer today than we did 10 years ago in comparison with Windows and MS Office. But the challenges in my bullet point list remain and overcoming them has been and will continue to be something we have to chip away at, one step at a time. And in the meantime linux and open source software is still doing extremely well in a lot of other end user facing market segments where the competition was not so strongly entrenched, like mobile phones, tablets, TVs, set top boxes, in-flight entertainment systems, in-vehicle entertainment systems, home applicances and so on.
Came back last evening from the GStreamer Conference and I am now back in Cambridge for the weekend. The GStreamer Conference was a lot of fun this year and it was great seeing everyone again. I think the mixture of talks we had this year was really good and I think everyone attending enjoyed themselves. For those who missed the conference this year then Phoronix and Lwn.net posted articles from the Conference. The talks where also recorded and will soon be available at the Ubicast GStreamer Conference website. We did try to get livestreaming going this year, but due to technical problems it didn’t work out, but maybe next year.
A big thank you again to our Gold Sponsor Collabora and our Silver Sponsors Entropy Wave, Fluendo, Igalia and Google. Thanks also goes to LWN.net, Phoronix and Ubicast for making sure the talks and sessions at the GStreamer Conference can reach a wide an audience as possible. And last but not least a big thanks to all our conference speakers who took the time and effort to prepare presentations for this years GStreamer Conference.
For me personally the GStreamer Conference this year also marks the end of my life in Cambridge, UK. Starting from next week I will have completed my period of comuting to Brno, and will instead be living in Brno, Czech Republic on a permanent basis. Which reminds me, we are looking to hire more members to our Brno desktop engineering team, so I will be posting a blog soon outlining what kind of experience we are looking for.
Spent today working on Transmageddon, trying to get it ready for the GStreamer 1.0 release. It is frustrating going as I only get a little time here and there to work on it, and thus my memory of the code is not as good as it needs to be in order to do this efficiently. But I did in the end manage to file a couple of GStreamer 1.0 bug reports and restore the preset functionality to almost where it was before the GTK3/GStreamer 1.0 port.
When starting the port I disabled and removed a lot of code that in retrospect I still needed as I made some wrong assumptions about how encodebin would work. Going over the code now I also realize I have done some things in a quite stupid manner, or maybe the approaches made sense in the original codebase and just now over a series of iterations have become cludgy, anyway tried cleaning it up a bit, but didn’t have the time to really go over the code and make sure it looks nicer.
Of big issues remaining is that the missing codec functionality is still not 100% restored and working nicely, so a little more work needed there. But if you have all codecs already installed then things are shaping up quite nicely. So I think I am getting very close to having a GTK3 and GStreamer 1.0 version of Transmageddon at feature parity with the GTK2 and GStreamer 0.10 version.
Also thanks to Kalev Lember, Transmageddon is now in Fedora (the latest 0.10 based release) and he also made me co-maintainer of the package which I a very happy about. Hopefully this means that when Fedora switches to GStreamer 1.0 I can get the new Transmageddon up and running there quite quickly.
Also Gendre Sébastien plans on working on Transmageddon going forward and have already made some really cool mockups for a revamped UI. A lot of new features are planned, like the number one request I keep getting, support for setting up batches of transcoding jobs instead of having to do them one by one like now. My plan is to release a first version with the current UI and featureset for GTK3 and GStreamer 1.0, and then work with Gendre to implement his ideas. This new UI will also be more GNOME 3 styled, so hopefully it will provide users with something that feels more at home in the GNOME Shell and on Unity.
Discovered yesterday that Paul Hunt of Adobe released a new font under a permisive license called Source Sans Pro. It looks quite nice and even adds Navajo support, probably as the first free font to do so. Hopefully we can get this packaged in Fedora and elsewhere quite quickly.
Another item that caught my eye is the Kickstarter for Oculus Rift, which is a VR glasses device which will include Linux support. Usually a bit sceptical about throwing out significant money on projects by people I don’t know off quite well already. But warm endorsements from people like Carmack and Gabe Newell convinced me that this was the real thing. With Gabe being so enamoured by it, maybe we can manage to get support for it in the Linux version of L4D2
Having just returned from GUADEC and now having the desktop as my job focus I been thinking about where we are going and what to do next. Benjamin managed to get quite a bit of press for his abysmally negative post, but I think his mis-stated the situation quite badly. As Dave Mason said during the history of GNOME talk, we have more or less always feel threatned and felt at times that we had an insurmountable task competing against systems with a lot more developers available than we do. There are some dark clouds in the skies, no doubt about that, but when hasn’t there been in the 15 years of GNOMEs existence? For instance the current tug of war between the GNOME shell and Unity? We have been there before, with Ximian and Eazel pushing competing visions for the GNOME desktop back in the day. Major corporate backers leaving (Nokia) or being in trouble(Novell)? Eazel and Ximian again. GNOME being perceived as being Red Hat only? That was the exact story that was being pushed before Sun and Ximian came on the scene. GNOME 3 turning away users? Hey, I can tell you that the amount of flames we got for GNOME 2 easily beats the GNOME 3 flames.
But for each of those events in the past we ended up bouncing back stronger afterwards, and I suspect we will come back with a vengance this time too. The thing is a lot of things are actually going very well. First of all the are a lot more shared projects with a healthy amount of resources behind them these days. WebKit is a great example of a project of crucial importance to GNOME, but which we share with a lot of other projects and companies. Take LibreOffice for example, yes LibreOffice do not contribute a lot of git commits to the GNOME git respository statistics, but thanks to LibreOffice we have the best and most full featured Office suite ever available to our users. And thanks to Firefox and Chrome we have browsers available with world known brands. And thanks to GStreamer, which is on freedesktop, we have a world class multimedia framework available. Instead of having our own sound server like we did with ESD, we now share a top notch sound server with all linux systems in the form of Pulse Audio.
Back during the GNOME 2 development cycle the GNOME project took an active decision that we would try to reach out to more of these external projects and try to work with them to integrate them into the GNOME experience. And we have succeeded at that, which of course have the side effect that instead of having all that development happen inside GNOME, we have bigger more active GNOME friendly projects doing these things outside GNOME.
We also made a conscious decision to focus on draining the swamp, which meant that instead of trying to work around issues and come up with funky configuration options on the user interface level to deal with missing features and bugs in the underlaying system, we instead have tried working with and contributing to fixing things in the underlaying levels. This of course moves attention away from ‘GNOME’, because people then commit their new fixes to those underlaying systems instead of implementing 100 000 lines of workaround code to ‘GNOME’, I mean I still consider Lennart Poettering a GNOME hacker even though his current work isn’t on anything in the GNOME git repository. But that does not mean that GNOME does not benefit greatly from these improvements.
So as we have succeeded in all these goals, GNOME should be a leaner setup than it used to be, as we don’t have to do all the heavy lifting inside the GNOME project anymore and that is a good thing.
As for projects such as Unity, well personally I don’t mind them at all. I mean I always saw XFCE as being a strenght and benefit to GNOME as it brought more users and developers to the shared library stack, and there is nothing different with Unity. And yes, there are some unfortunate duplications which seems redundant even in the context of differentiation, like the GNOME Online Accounts and Ubuntu Online accounts split, but hopefully we can work together to resolve such things over time.
And as for taking the desktop to the next level I think the main challenge for GNOME is not inside the GNOME 3 desktop, but instead it is a question of if the open source community can come together around pushing things like the Linux OpenGL support forward and make sure we have a strong foundation for supporting games and improving visual effects in the desktop. I for one really hope that Valve’s decision to support Linux with Steam, and the success of the Humble Bundle games on Linux, will help rally support behind the efforts to get Mesa to support newer iterations of OpenGL and get the open source Nvidia and AMD drivers in shape. Microsoft has long ago abanndoned PC gaming in favour of the Xbox, lets see if we can make Linux fill the gap.
In general I am very optimistic about the future, the strenght of the open source ecosystem is not that we have more developers to assign to a given project at a given time than Windows or Mac, but no matter what they do we keep moving forward on all fronts, so while Apple and Microsoft focus on beating each other in the tablet and phone space, maybe the time is ripe for us to strenghten our positions in the server and desktop markets? I mean tablets and phones might be all the rage atm, and maybe they are bigger markets than the traditional server and desktop market, but the server and desktop markets are still huge and ripe with opportunity if we play our cards right. And if we can deprive Microsoft of things like their Office cash cow, then that levels the playing field all the more when we later take them on again in other areas.
