Thursday, July 16. 2009Apple breaks Palm Pre compatibility. Or: an open letter to Palm
Dear Palm,
When you launched the Pre everyone was very excited about the excellent job you did. Everyone except Apple that is, they don't like such strong competition. You decided to reverse engineer the iTunes database "protocol" used in Apple products and implemented it from the device side on the Pre. This has the benefit of being able to sync the Pre with iTunes on any PC or Mac without installing extra software. And you didn't have to invest in development of your own desktop software, which is not a differentiating feature for you. You're in the business of selling phones, not software. I don't think deciding to "outsource" this to Apple was a smart move though. So now the bully is attacking you on their playground:  From Engadget Mobile And then they say it's your own fault. You could go crying to the principle (or whatever you want to call court you want to file the anti-competitive lawsuit with). But if you have a problem, if no-one else can help, and if you can find them, maybe you can hire the AMAROK-TEAM! The media-player support in Amarok 2 is shaping up to be very flexible, complete and easy to implement thanks to the hard work of 2nd time GSoC student and hacker extraordinaire Alejandro.  We can quickly add support for the Palm Pre, or any other player, providing there is a way to access the database and we have documentation of the data-format. We already have iPod and MTP support and the same system is used to implement audio CD as a collection. iPhone OS 3.0 is being worked on as well as UMS (generic USB device) and OBEX (many cellphones). We promise not to change our application to prevent users to use Amarok with your device. Not only do we care about our users, we are not a competitor to you or have any ulterior motives. Amarok is already fully supported on all flavors of Linux and we have beta releases on Windows and Mac OSX which just need a bit of polishing and stabilization. Serious business proposals can be send to the Amarok team at business@getamarok.com (these emails will not be publicly readable).  Saturday, June 13. 2009UPnP DevSprint in Paris Hi from Paris, where together with [ade], dev, erwan, philn and lightyear I'm at the Coherence/KDE developer sprint focused on UPnP. Yesterday, after struggling with QtDBUS (specifically the under-documented qdbusxml2cpp) I managed to the signals from Coherence and call functions. So now I can discover the devices on the network. The signals are connected to a UPnPCollectionFactory that should create a new collection for each mediaserver (containing music) on the network. Next step will be to really talk to the devices themselves. That will require some XML parsing, which can get a bit complicated. With any luck I'll find a Qt based DIDL-lite parsing library.

During FOSDEM [ade] and I met with Frank Scholz, the lead developer of Coherence. We discussed DLNA/UPnP and how Coherence can be used in KDE and Amarok. The conclusion of this meeting was that we should use Coherence as our base for supporting UPnP services in KDE. The first implementation will be a KIO slave for browsing media stored on remote devices.
UPnP is a network technology using a combination of SSDP, XML and SOAP, with some GENA thrown in for eventing. A group of UPnP services called the UPnP A/V Architecture has been picked up by an industry organization called the Digital Living Network Alliance. DLNA specifies device classes which have to implement specific services and support a minimal set of filetypes and codecs. Coherence is a framework, written in Python but it exposes a DBUS API, that allows an application to participate in the "Digital Home Network". For the moment this means mainly UPnP, but support for Ampache is available and Apple's DAAP is also considered. It's published under the MIT license and is multiplatform. In Amarok we have been planning to integrate UPnP for a long while. But except for a failed Google Summer of Code project last year not a lot of effort has been spend. Thanks to Coherence this will quickly change: in relative short term (read 2.2) we will introduce a UPnP Collection that will list and enable playback of music stored on a DLNA Digital Media Server.  We could even consider publishing the content in the local Collection, basically making Amarok a DMS. Amarok can then track plays on remote devices and use it in the scoring algorithm. Even more advanced functionality would be to control one or more Digital Media Renderes, such as the Philips Streamium, from Amarok. A few mails have been going back and forth between interested developers about discovery of network services in general. In order to simplify using technologies as UPnP, zeroconf, Samba, etc I'm wondering if we can integrate this in Solid. Only the discovery part obviously, using the services would be the task of separate frameworks, such as Coherence. With this functionality in Solid it should be trivial to show a kind of "Network Map" to the user with all the services per device. As you can tell, plenty of cool things to keep a few people busy for a year or 3. Bart  Saturday, June 13. 2009Amarok Junior Job: Auto-download new podcasts
A recent comment by progmanos on the post of the 2.0.1.1 release reminded that I still have to implement Podcast episode auto-downloading. In the hurry to get 2.0 released I did add the config option, but forgot to add the actual code to make it work.
 In Amarok 2 Podcasts are implemented in classes derived from PodcastProvider. There can be mutliple providers, which allows for instance podcast syncing between Amarok and an iPod. The default provider is SqlPodcastProvider. This is where the auto-download function should get implemented. This is a nicelly contained and not to steep introduction to Amarok development. So it's an excelent Junior Job. If progmanos or anyone else would like to have a go at it, contact me on #amarok on irc.freenode.net. My nickname is Stecchino.  Saturday, June 13. 2009Amarok podcasting 2.0 and post-2.0 plans
Hey fellow developers and users,
In Juli 2007, at Akademy Glasgow I started implementing podcasting support in Amarok2. Since then I was sidetracked a little, as you may be aware. The little time I did manage to spend designing and implementing was short and far from focused. So a lot of features are not finished or just plainly missing. The framework I created underneath suffered from the same lack of focus and is need of a good review. I'm aware there is probably some overdesign and some parts might be to complex. If you feel you can help in that area I suggest you take a look at extragear/multimedia/amarok/src/podcasts . Send questions, comments and suggestions to amarok-devel@kde.org . The 3rd beta from Amarok 2.0 is already out the door and podcasting support is still not finished. In order to make it I had to reduce some goals I had set for myself during those rainy summer days in Scotland. Here's the plan: Amarok 2.0: The focus ATM is on finishing the SqlPodcastProvider, Podcastmodel and PodcastCategory (GUI). SqlPodcastProvider uses tables in the standard SQL database, adds and updates the feeds using PodcastReader and downloads to disk using the regular KIO-jobs. To make the podcasting fully functional though we'll need to reintroduce:
.The GUI currently shows all episodes ever read from the feed, which obviously needs to be addressed. The GUI for 2.0 should be very similar, if not identical to Amarok 1.4, probably minus folder tree grouping support since that is better handled generically for all Playlists (which PodcastChannel is in our class diagram). If anyone has a bit of Qt Model/View experience and would like to see podcasting in Amarok 2.0 I suggest you send a mail to amarok-devel@kde.org or ping me on irc (Stecchino on #amarok). Without help we might have to drop it's from 2.0 completely because it's a bit much for me alone to complete and stabilize. Amarok > 2.0: I do have a plan for a complete GUI overhaul post-2.0. I'll get some art and usability advice in another blog post when the time comes. The 2.x releases should see more advanced features being introduced that the framework is already designed to support: For the SqlPodcastProvider specifically:
