Akademy, development catalysator

While most of my fellows at Openismus are currently in The Hague for the GUADEC (after all those who are there are Gnome users and developers 😉 ) I got aware that this year’s edition of the conference for users and developers of KDE software, Akademy, is already a few weeks ago again, time to complete and dump my blog entry about it. (And time to welcome next year’s joint event, so all Openismus people will be at the same place at the same time 🙂 ).

After more than two month with almost no work on KDE stuff (due to broken backlight on old laptop, starting as employee at Openismus and for this moving to and settling temporarily in Helsinki, getting a new shiny laptop but with completely broken kernel drivers for the GPU) I was happy to be able to dedicate my full time to KDE stuff again, by rushing some development setup onto the laptop I temporarily have for work and start hacking on the things that had been stuck over the recent month, especially with all the people around I need to talk to for that:

Okteta plugin to KDevelop
I had started that plugin at the Kate-KDevelop sprint this February. It was basically working already, but there was no way to actually trigger the loading of any file as byte array, and without any sufficient clues about the architecture and not much time to do the needed communication via email and irc this integration plugin just bitrotted in playground. Now with Alexander Dymo and Millian Wolff sitting just at one of the other tables I was a matter of preparing my questions for them (and solving part of the problem myself, as you do usually) and some little conversation, and done it was. The only showstopper are a bug in the KDevelop platform itself, worked on, and needing to wait for the SC 4.5 release next month, as only then the headers of the Okteta libs are published, which these plugin uses.

network:/ kio-slave
This kio-slave is part of the SC since 4.3 (in kdebase/runtime, try network:/), but since then lacking further polish and better integration with Places, bookmarks and the remote:/ kio-slave. At least one one of the biggest hurdles, the overbending of the KIO concepts, by introducing mimetypes for the service items (for a nice representation in the view), which on a click forward to a proper url of that service, which may deliver an item of another mimetype, but that is not expected.
I was lucky to find time slots at one of the clones of David Faure present who showed his deep code knowledge and quick solution ability. So starting with the RC3 the network:/ kio-slave finally starts to get usable and can be promoted a little more 🙂

Cagibi
Claiming that the network:/ kio-slave was just sitting there and lacking further polish is only telling half of the truth. Last october at a sprint in Barcelona with the nice boys from Coherence I did an initial implementation of a UPnP backend, so also the devices/services as announced within the UPnP system are listed in the network, at least their root device with a link to the device’s webinterface if present (presentation url).
Since then some time has passed, and as I needed only the SSDP part of UPnP for the network:/ kio-slave, running a feature-full daemon like Coherence was not the best solution, so under the name Cagibi I threw together some custom code for a prototype of a SSDP cache/proxy, as also once upon a time proposed by Armijn Hemel, the long-time pusher for UPnP support in KDE.
With Armijn present, I could demo it to him, so he could see first fruits of his (and Adriaan’s) sprint sponsoring efforts related to this. How and when you can see it (like in SC 4.5 ?), will be topic of the next post.

I also was glad to meet, amongst others I was glad to meet of course 🙂 , Nikhil Marathe, who works to finally bring the UPnP mediaserver kio-slave into existence as his GSoC 2010 project, being mentored by Bart, who started on that during the sprints with Coherence. And so Nikhil can demo more fruits, and they look tasty. The days are counted at which you cannot access your files on your X-Box (or whatever closed system you have exposing a UPnP mediaserver) from Amarok, Dolphin or any KDE platform filedialog.

And I got a lot of inspiration from all the workshops, for going on with going Mobile, for getting our personal and open share in the Cloud, for linking our minds and data models with Telepathy, and what not.

This year’s Akademy was great, thanks again for everyone involved to make it happen as it did!
