2014-07-22 Meeting Minutes

2014-09-15 18:13 UTC  by  peterleinchen

Meeting held 2014-07-22 at 20:00 UTC on FreeNode, channel #maemo-meeting (logs)

Attending: Ruediger Schiller (chem|st), (xes),
Jussi Ohenoja (juiceme), Philippe Coval (RzR), Peter Leinchen (peterleinchen)

Partial: Joerg Reisenweber (DocScrutinizer05)

Absent: Niel Nielsen (nieldk)

Summary of topics (ordered by discussion):

  • IRC cloaks
  • administration of IRC channels
  • certificates problem
  • HiFo / MC e.V. transfer
  • future of Harmattan
  • listing of resources

Topic (IRC cloaks):

  • As proposed last meeting by sixwheeledbeast the necessity and the basics (privacy) of cloaks on IRC was discussed briefly.
  • As no one claimed to need that, no decision was made. Possibly to decided next meeting.
  • Discussion faded smoothly to next topic...

Topic (administration of IRC channels):

  • DocScrutinizer05 claimed the non-existence of any administration rights for Maemo affiliated personnel.
  • The only person with IRC administrative rights seems to be Nokia/x-fade.
  • rZr is going to contact x-fade and convince him to add a member of current council to GC (GroupContact) or inform IRC admins to do so.

Topic (certificates problem):

  • chem|st stepped in and announced that all problems regarding certificates and also IRC administration will get solved as soon as the Maemo ownership/licensing is solved.
  • This is work to be done by HiFo (resp. MC e.V.), but community may help getting the website straight by editing the documents in this thread.

Topic (HiFo / MC e.V. transfer):

  • chem|st explained a bit about the current situation of HiFo (Woody is going to close the American HiFo bank account) and registering of MC e.V. (registration still needs to be confirmed by court).

Topic (future of Harmattan):

  • MeeGo/Harmattan is closed down by Nokia. But it is not clear where the rights for Meego/Maemo6/Harmattan are at the moment.
  • FOSS source DVD of Harmattan is available and may be hosted on (but not to consider due to resource limiting on current infra).
  • Firmwares/flasher and so on (binary blobs) will most probably never be available like the ones from Maemo (due to binary blobs of 3rd parties).
  • Other resources in question are the SDK repo and some development stuff (scratchbox, VMs).

Topic (listing of resources):

  • It was clearly discussed that hosting of above mentioned resources will be against the law. But a named listing of those resources togther with a md5sum (better: sha1sum) will be okay.
  • So we ask community to step in and help listing those resources. Please see rZr's post or edit directly here.
  • A listing of files available on Nokia's NDS fire servers is also welcome but are to be seen as temporary solution, as those servers are foreseen to close down in near future (at least for our resources).

Action Items:
  • RzR trying to contact x-fade.

profiling is not understanding

2014-09-12 18:06 UTC  by  Robin Burchell
When software goes slow, generally, the first reaction is to profile. This might be done through system tools (like Instruments on OS X, perf/valgrind/etc on Linux, VTune, etc). This is fine and good, but just because you have the output of a tool does not necessarily correlate to understanding what is going on.

Streaming the Screen on Android

2014-09-11 22:37 UTC  by  madman2k

In this post I want to discuss way of getting the screen content of your Android device to the TV or monitor. If you wonder why one might want to do such a thing – just think about playing some Android games with a bluetooth gamepad or watching a movie where your PC is not available.

Specifically I want to introduce SlimPort. SlimPort is a feature of Nexus devices which is unfortunately not covered much in reviews.
Basically SlimPort is DisplayPort over the Micro-USB connection of your device allowing you to mirror its display.

But the future has arrived: we got Miracast!

One might wonder why one should go through the hassle of using a old-school HDMI cable.
You can get a Chromecast Stick for 35$ and nowadays it also supports Miracast so you can simply stream the images over WiFi.

Well Miracast is all nice if all you need to do is to put up some slides without carrying all possible adapters with you. But as soon as you try to stream a movie or a game you will reach its limitations.

Remember that Miracast works by grabbing the Framebuffer and compressing it with H.264. While encoding happens in hardware it still takes some time and it inevitably introduces compression artifacts. This means:

  • in games you get a noticeable lag – especially in FullHD
  • in movies you get noticeable artifacts – especially in FullHD
  • in both cases your battery will get drained for heavy WiFi and Encoder usage
Going old-school

Going with the old-school cable on the other hand you get HDMI 1.4 transfer rates for up to 1080p at 60Hz while saving the battery.

Configuring the second screen is quite straightforward in android. As Mirroring is your only option, there is actually nothing to configure. Once you connect the adapter android will set up your monitor based on its EDID information and transfer image and audio over HDMI.
In case you only want to have the image over HDMI, simply attach your speakers to the phone and android will re-route the audio.
The days where you had to manually set up everything are over.

Furthermore most adapters have an micro-USB port allowing to still charge your phone while using SlimPort.

Device Support

The downside is that most of the devices do not support SlimPort. The device list more or less boils down to

  • Google Nexus 4/ 5
  • Google Nexus 7 (2013)
  • LG G2/ G3

Samsung devices go with the alternative MHL. Comparing these two SlimPort has the bandwidth advantage of 5Gb/s vs. 3Gb/s of MHL so it does not have to compress that much. However both are clearly better than going wireless.

PADI Rescue diver

2014-09-01 16:25 UTC  by  Philip Van Hoof

For this one I worked really hard. Buddy breading, relaxing people in panic at 20 meters deep, keeping yourself cool. And that in Belgian waters (no visibility and freezing cold). We simulated it all. It was harder than most other things I did in my life.

sailing in search of fresh waters

2014-08-13 11:55 UTC  by  Robin Burchell
I've had a long, quiet time on this blog over the past few years while I've been frantically helping Jolla to launch their self-named product: the Jolla. I've enjoyed (almost) every day I've been there: they really are a great bunch of people and the work has been plentiful and challenging.

But as the saying goes, "this too shall pass". Nothing lasts forever, and it's time for a change: after this week, I will be taking a break from Jolla to get some fresh perspective.

On the bright side, maybe I'll have some more time for writing now :)

If anyone is interested in getting a hold of a C++/Qt/QML/Linux expert with a focus on performance, expertise on mobile, and a wide range of knowledge across other areas who loves open source, please let me know.
