I've spent the better part of the day with , renaming files/functions/include paths, Makefiles, autotools and the like. The result of this is a new sub-project called libosmocore that gathers all the shared code between the network-side GSM ... [More] implementation OpenBSC and the phone-side implementation OsmocomBB. The library is portable enough that it can run on a proper OS (like GNU/Linux) but also be cross-compiled to work on the actual phone without any OS. On the other hand we now have a master Makefile in OsmocomBB to build libosmocore for host PC and target (phone), as well as the osmocon and layer2 host programs and the phone firmware itself. Let's hope I can now return to writing actual code... [Less]

Last, but not least, I am proud to announce the OsmocomBB project publicly. During the last 7 weeks, a small group of skilled developers has been working on this It has now reached a point where we can scan the spectrum for the strongest signal ... [More] GSM channels lock onto them and performing AFC (automatic frequency control) decode the SCH burst to obtain BSIC and GSM frame time decode the BCCH of the cell, pass it over to the host PC and feed it into wireshark Since this in itself is a valuable and useful milestone of the project, it was the ideal opportunity to take this project public. There's still a lot of work to be done in many areas. Most of them are not even related to the GSM air interface. So if you're familiar with C development on an ARM7TDMI based microcontroller, know your way around I2C and SPI, are familiar with the GNU toolchain for ARM and want to help us out: Please join the baseband-devel mailing list right away!

Am 9. Juni 2009 war es endlich soweit – Fedora 11 wurde nach zweimaligem Verschieben um jeweils eine Woche endlich veröffenlticht. Nachdem ich nun seit ca. einem halben Jahr Fedora 10 benutzte und sehr zufrieden damit bin, war es auch für mich soweit ... [More] die neue Version der Distribution aufzuspielen. Zum Upgraden auf eine neue Fedora Version gibt es das Tool “preupgrade”. Dieses lässt sich ganz einfach mit folgendem Befehl starten. preupgrade Man wird nach dem root-Passwort gefragt und wird von einem Software-Assistenten grafisch durch das Upgrade geführt. Sind alle neuen Pakete fertig gedownloaded, so wird man gebeten den Computer neu zu starten. Beim nächsten Start, installiert sich das Upgrade dann automatisch. Dies kann jedoch einige Zeit dauern (bei mir knapp zwei Stunden). Hierzu ein paar Screenshots: [gallery link=“file”] Nach einiger Zeit ungeduldigem Wartens und einem weiteren Neustart kann man dann sein neues Fedora 11 benutzen und hat alle alten Programme, Dateien und Konfigurationen noch erhalten. Zu bewundern gibt es dann unter Anderem: Gnome 2.26 Firefox 3.5 Thunderbird 3.0 Kernel based Mode-Setting & Plymouth den freien Nvidia Treiber “Nouveau” in der Standardinstallation NetworkManager 0.7.1 ein neues Pulse-Audio Soundmanagement inkl. neuem Lautstärke-Applet uvm… Die vollständigen Releasenotes gibt es hier: http://docs.fedoraproject.org/release-notes/f11/de-DE/ Ein Upgrade lohnt sich auf jeden Fall. Fedora ist super! Wer Fedora 11 neu installieren will, kann es sich von der Homepage des Projekts downloaden: Downloade dir jetzt Fedora [Less]

Today I decided to try out the picture-viewing-app “neon” [1] [2] on my Freerunner. This app is really amazing! It is pretty fast and provides very cool features like auto rotating images by dimensions, auto rotating window using accelerometers and ... [More] of course zooming, manual rotating images, slide-show, the basic stuff. And if you use the b_and_w theme it looks pretty elegant. All in all i can say: I love this app! And therefore i created a ticket in the SHR-Trac to add neon to the SHR-Feed [3]. After a while of using neon I found a few things that couldn’t satisfy my expectations: 1st the white background of the b_and_w theme, which is visible if a picture doesn’t fill the screen. But a short look in the neon-SVN and one edje_cc later I had created a edje-file for b_and_w theme, which has a black background [4]. 2nd issue was that the display of the Freerunner blanked while looking at pictures. This is where “fsoraw” [5] [6] comes on. Fsoraw (FSO Resource Allocation Wrapper) is a wrapper utility to launch applications preallocating system resources from FSO. That means you can activate e.g. the “Display”-resource, just by editing the .desktop file of an app. This way I edited my /usr/share/applications/neon.desktop to allocate the “CPU” and “Display” resources, to avoid suspending and display blanking. Furthermore, I customised the neon parameters to activate the picture and window auto rotating stuff, to use the b_and_w theme and to start in my “Bilder” (=pictures) folder. The Exec line of the .desktop file now looks like this: Exec=fsoraw -r CPU,Display — neon -f -r 0 -R 1 -t b_and_w /media/mmcblk0p3/Bilder Have fun with neon and use fsoraw (e.g. for mokomaze, too): Exec=fsoraw -r CPU,Display mokomaze [1] neon project page [2] neon in om-wiki [3] shr #596 [4] download this edje-file [5] fsoraw project page [6] fsoraw in om-wiki [Less]

I just found this little EFL-testapp: It’s an app written by Gustavo Sverzut Barbieri. It’s an Iphone like virtual keyboard. You can find the sourcecode on googlecode.. I had to apply a little change to the code, to get it running on the Freerunner. ... [More] I changed lines 206-210 to this: if ecore.evas.engine_type_supported_get(“software_16_x11”): ee = ecore.evas.SoftwareX11_16(w=WIDTH, h=HEIGHT) else: print “warning: x11-16 is not supported, fallback to x11” ee = ecore.evas.SoftwareX11(w=WIDTH, h=HEIGHT) Maybe someone likes to modify this code and build a real virtural keyboard for SHR out of it? I hope i could motivate someone, as this would be a really nice keyboard. [Less]

Just a quick blog to say that the old Clutter Odo demo now lives in Mx as a dedicated widget. Its been tidied up so that it's much easier to use and animate. Also in the video, MxWindow which uses client-side window decorations and demonstrates ... [More] Clutter's support for argb visuals under a compositor. Note that of course the video isn't recorded at 60Hz and also impacts on performance - this runs silky smooth on typical netbook hardware. Download video As always, Mx is available from git at git://git.moblin.org/mx [Less]

D'un côté : Nokia avec le projet Maemo.De l'autre : Intel avec le projet Moblin. Et bien c'est désormais officiel : les 2 projets opensources fusionnent pour donner naissance à MeeGo. Les 2 géants avaient déjà annoncé un accord autour de logiciels ... [More] basés sur Linux "qui dépasseront le cadre des smartphones, PC portables et netbooks actuels pour se concrétiser par des équipements, des logiciels et des services Internet mobiles innovants". Cette nouvelle plateforme ouverte et gratuite sera hébergée par la Linux Foundation.Elle devrait tirer parti du meilleur des deux mondes pour viser de nombreuses cibles : téléphones fixes et mobiles, Netbooks mais aussi systèmes embarqués dans les véhicules, les téléviseurs et autres appareils multimedias. Rappelons qu'en face se trouve Google avec Android et Chrome OS. [Less]

It seems the problem with those weird libcurl errors when you enabled the secure option (basically https) is that the ca certificate bundle is missing in SHR’s OE build (perhaps it’s on all OE builds, don’t know). There is, fortunately, an easy way ... [More] to fix it (as mentioned in the openmoko communiy list). All you need to do is copy your own ca certificate bundle (in Fedora it’s /etc/pki/tls/certs/ca-bundle.crt ) into the proper place for OE’s path: /etc/ssl/certs/ca-certificates.crt So now you can enable secure, rather than faster [Less]

A violinist playing in the Washington DC Metro Station on a cold January morning in 2007. He played six Bach pieces for about 45 minutes. During that time approx 2 thousand people went through the station, most of them on their way to work. After 3 ... [More] minutes a middle aged man noticed there was a musician playing. He slowed his pace and stopped for a few seconds and then hurried to meet his schedule. 4 minutes later the violinist received his first dollar: a woman threw the money in the till and, without stopping, continued to walk. 6 minutes A young man leaned against the wall to listen to him, then looked at his watch and started to walk again. 10 minutes A 3 year old boy stopped but his mother tugged him along hurriedly, as the kid stopped to look at the violinist. Finally the mother pushed hard and the child continued to walk, turning his head all the time. This action was repeated by several other children. Every parent, without exception, forced them to move on. 45 minutes The musician played. Only 6 people stopped and stayed for a while. About 20 gave him money but continued to walk their normal pace. He collected $32. 1 hour He finished playing and silence took over. No one noticed. No one applauded, nor was there any recognition. No one knew this, but the violinist was Joshua Bell, one of the best musicians in the world. He played one of the most intricate pieces ever written, with a violin worth $3.5 million dollars. Two days before Joshua Bell sold out a theater in Boston where the seats averaged $100. This is a real story. Joshua Bell playing incognito in the metro station was organized by the Washington Post as part of a social experiment about perception, taste and people’s priorities. The questions raised: in a common place environment at an inappropriate hour, do we perceive beauty? Do we stop to appreciate it? Do we recognize talent in an unexpected context? One possible conclusion reached from this experiment could be: If we do not have a moment to stop and listen to one of the best musicians in the world playing some of the finest music ever written, with one of the most beautiful instruments …. How many other things are we missing? That was an email sent from a friend. Like a cold shower, I’m still deeply stunned. [Less]
