On MeeGo
Whatever MeeGo was, it never made it into the open source mainstream, which I consider to consist of projects actively worked on by volunteers and companies alike, and didn’t manage to become an project attractive enough for individual open source enthusiasts not driven by money to make substantial contributions.
There is enough room to speculate over the reasons why this is. My personal take is that MeeGo failed to be a successful open source project because the corporate commitment to the open source idea was not strong enough and expectations were too high right from the start.
Open source projects start with an idea and evolve into a proper product over time. Sometimes they are developed incrementally, sometimes it happens that big parts of them are replaced all at once. The idea behind an open source project may be huge but they all start off with baby steps. MeeGo, however, wasn’t supposed to. The idea behind MeeGo was big, and due to market pressure it was expected to become complete and successful quickly. It occurs to me that the idea was to sort of guarantee success by providing the project with professional, corporate governance.
I think everyone who started working on open source as a hobby knows that this is something a lot of hackers don’t are comfortable with. An open source project under corporate leadership may easily suffer from top-down decisions that give developers the feeling of working in a restrictive environment rather than a playful one. I’m not surprised by the fact that the only people I know ever contributed to MeeGo worked either for/with Intel or Nokia.
It isn’t the technologies, tools or frameworks that are reason for the failure of MeeGo. KDE and GNOME are large and successful projects based on Qt, GTK+, Clutter, D-Bus-based desktop middleware etc. What has lead to failure in my eyes—-the eyes of an outsider, opn source developer and potential user—-is that the dynamic nature of open source projects conflicted with corporate expectations and hopes for a quick success they needed so badly. Add to that the pressure on Nokia, the corporate culture clash of two global information technology companies and the fast pacing world of mobile devices and interfaces, and you have a pretty explosive mixture.
Personally, I won’t place my bets on Tizen. I can only imagine how frustrated and disappointed everyone who tried to get involved may be today, even those who contributed to MeeGo as part of their work for Intel, Nokia or one of the many smaller companies that make up the corporate part of the open source ecosystem. It is also frustrating for me as a developer aiming for a job in open source and desktop/mobile/UI technologies.
I guess the mobile open source platform we are all hoping for will be there some day. But it will only appear slowly, driven by the efforts of enthusiastic individuals with big ideas, realistic expectations and sound knowledge of the pace and dynamics with which open source projects grow and mature. This of course relies on open hardware and I don’t know enough about the manufacturing industry to predict the availability of open, hackable devices in the near future.
In the meantime, the best we can do as open source software developers is improve the base OS level and innovate in desktop/mobile/UI technologies by experimenting with new ideas and extending existing frameworks. I’ll help where I can.
Hiding backup files in Thunar
There was one feature in the new Thunar with GIO (since Xubuntu 11.04 Natty) that I didn’t like. It was stubbornly showing backup files (*~). I asked the Thunar developer Jannis Pohlmann today if there is a solution/workaround for that, and there definitely is!
Close Thunar, add the line MiscShowBackup=FALSE at the end of your ~/.config/Thunar/thunarrc and launch Thunar again and you’re not seeing the backup files anymore. What a relief. Thanks Jannis!
On a sidenote, I’ve finally started making decent, serious backups of my (Open Source) work. The rsync-based script works better than I could have ever imagined. Thanks go to Marko for that.
Looking for a full time job in Open Source
Two years ago I was really close to canceling my studies and looking for a job instead. In the end I continued studying, passed the final exams of my Diplom (the German old-school equivalent to a Master’s degree) with excellent results and started working on my graduate thesis. Today, I am 1 1/2 months away from the submission deadline and it is clear that I will make it.
So, this time I’m serious: I’m looking for a full time employment in Open Source software development, engineering or management starting November this year. Hiring me will get you an experienced and talented hacker with a natural intuition for software architecture and aesthetics as well as a scientific and painstaking approach to software planning and implementation.
Through my work at the university and within the Xfce and Lunar Linux projects, I have gained experience in/with
- many programming languages (including C, C++, Ruby, Python, Vala, Lua, XSLT, TeX, Java, Bash and a couple of others),
- many frameworks (the whole GTK+/GLib stack including D-Bus, a bit of Clutter, XLib and Qt/QML, SWT/JFace, the FOX toolkit as well as web frameworks like Sinatra and Rails; some knowledge about the Linux kernel, its facilities and kernel-userspace communication mechanisms included),
- many developer tools (GNU compilers, Autotools, VIM, NetBeans, Eclipse and others),
- many software versioning systems (Git, Subversion, CVS and Mercurial), and
- various areas of computer science and software engineering (complexity theory, signal processing, graph drawing, micro-controller programming and sensor-based networking, software planning, testing etc.).
I feel equally at home developing for the desktop or for the web. Granted, my main area of expertise is user interface and middleware development on Linux, which my fellow Xfce hackers and I have successfully participated in, but I’ve always found web development with Ruby to be a refreshing change.
There are many other things related to open source that I love doing. Over the past years I’ve enjoyed being able to improve the transparency of the development and release management of Xfce. Streamlining the release process and providing tools for making release management fun was an initiative I am particularly proud of. The same goes for community efforts like the Xfce Foundation, which we’ve launched in early 2011 and which I am currently heading as president.
This post is not just about the past though, it’s also about what lies ahead. Things I am particularly interested in with regards to the future include
- mobile platforms and applications (iOS and Android are not good enough, I think we need open alternatives),
- multi-touch interfaces on Linux (yep, this is on the way, but there still is a lot of potential work to be done, I guess),
- cloud-based applications (I know I can store files and data on the web, but where are the mind-blowing features that go beyond availability of personal data everywhere?), and
- environmental and power saving applications (living responsibly will become important soon enough; how can we generate awareness and support environmental causes with the help of software?).
I am excited and curious what my role will be in all this. Anway, I guess this is enough information about me for now. After all, this is no biography but a job-search post. ;)
If you read this and you happen to be Microsoft or Apple, do not even bother to send a headhunter. I prefer to work in the open and I believe in Open Source for many reasons. This ecosystem that we’ve created over the past two decades provides a great way for people from all around the world to collaborate on projects they care about, in an honest and tolerant way. I think that’s an inspirational model from which our entire society can and hopefully will benefit. Why would we want to have it any other way?
If you are a member or leader of a company dedicated to Open Source software and are interested in hiring me, please let me know. Linked below are my resumé, software projects and email address. I’m looking forward to talking to you!
Download my resumé/CV — A list of references is included. Feel free to contact them; they are aware of being listed and I’m sure they will be happy to answer any of your questions.

Xfce 4.8 with Conky
I have been following a short discussion on the IRC channel #xfce regarding an issue with the use of Conky and transparency. I didn't use Conky for a very long time, but since I knew it was possible to have Conky perfectly running, I gave it a shot again and since I did a fresh reinitialization of Xfce on my workstation, I tweaked the configuration file to my need. Now I have it running in the background and I'll most probably keep it.The configuration I was able to get for a good working Conky window with transparency is bellow. Of course I could tell you which combination doesn't work, with the why, but since there are so many of them I simply put a working one.
own_window yes # create a separate XWindow over the one from Xfdesktop
own_window_type desktop # the window cannot be moved or resized
own_window_hints undecorated,below,sticky,skip_taskbar,skip_pager # make it behave like it belongs to the desktop
own_window_argb_visual yes # true transparency, a compositor has to be active
own_window_argb_value 100 # make the background semi-transparent
double_buffer yes # avoid flickering
Here is a screenshot of the desktop with Conky in the bottom right corner, I made sure there is some I/O activity going on :-)

Xfce mailing lists moved
The Xfce mailing lists moved from foo-projects.org and are now all hosted at mail.xfce.org. Mail addresses were not changed so nobody should experience problems with this, if you do please contact us at postmaster@xfce.org.
We want to thank the foo-projects.org crew (yes you Auke) for excellent support in the last couple of years!

Analysing a phishing email
I've been hit by several phishing emails in a short time the last week. Having time this morning I took the initiative to look at the headers from one email and the phishing location.The hosting server
The domains DNS zone is hosted on a particular network just like its website. Two different servers actually, but behind it seems to be a lucrative webhosting service where you can get your domain registered although it's not a registrar. All of this is hosted in Texas.
The email server
The email is originating from Italy. The FROM address is set up to show a truthful email (usually where you put the surname) with an inexistant email address behind that. The email address' domain name exists however and is hosted in France, but has no relation to the scam, at least the owner of this domain can't do anything about it.
The Return-Path shows a real email address with a different domain name but same network anyway. The domain name shows a dummy webpage "Under construction".
Who to contact?
All of them if you care, otherwise just let it go, because phishing pages are set up and down daily...
To contact the webhosting or email server, request the Whois information of the IP address and contact the abuse department, there is always an abuse section in the Whois of an IP address. You can also contact the domain name holder and/or look if the registrar or webhosting sevice has a dedicated abuse website page.
Of course it happens that an abuse email address forwards everything to the trash can. In order to have a chance to stop the scam, it is good to contact as many services as possible.

Irrational behaviour
So, I want a new phone. I really don’t need one, but I want it anyway.
This is my current phone:
And it fits my needs perfectly: water/dust/sand(!)-proof — Leonie and Guido are 3 and 1 year old now, so this is not a useless feature at all ;-) Moreover, it lasts two weeks without recharging and I only use it to make phone calls, so I don’t need anything with more features.
Still, I want this phone:
Basically, I’ve fallen for the pretty pcitures and UI demos, but I tell myself it is because it runs “real” linux.
What’s wrong with me? ;-)
Xfce Design SIG launches
As Jérôme Guelfucci wrote in his blog earlier, a special interest group has been started. The Xfce Design Special Interest Group (or SIG) has a clear purpose (quote from the groups wikipage):
The Xfce Design SIG aims at improving the usability and visual appearance of the Xfce desktop environment. Our goal is to bring interested users, designers and hackers together to ensure neither of them is working in a vacuum. By establishing a context in which they can collaborate on smaller and larger design-related projects we try to increase the chance of the proposed changes to be merged into the official Xfce repositories.
I’m looking forward to working with Xfce directly and more closely after working years with Xubuntu. It’s both easier for us and assures that all Xfce users can enjoy the improvements, not just those who use Xubuntu.
Are you interested specially about Xfce Design? Join us!
