Re: Muting the ring tone on incoming call on N900
Hi, the phone mutes the ringing if you turn it face down while it rings. Maybe you can capture this action with the D-Bus monitor. Martin 2011/8/25, Miko Kiiski miko.kii...@vincit.fi: Hi! I'm trying to build an application that mutes the ring tone that is played when I receive a phone call. I have been browsing through the documentation and trying to find the dbus call for this purpose using dbus-monitor, but up til now, have had slim success. Thus far I have tried the following: I've tried to call the org.maemo.Playback.Manager /org/maemo/Playback/Manager org.maemo.Playback.Manager.RequestMute dbus method with the argument set to true. I have read the documentation from http://wiki.maemo.org/Dialer, and AFAIK it this should do just what I want. However if I call that method, nothing happens. Here is the command I've used: dbus-send --session --type=method_call --print-reply --dest=org.maemo.Playback.Manager /org/maemo/Playback/Manager org.maemo.Playback.Manager.RequestMute boolean:true Reply: method return sender=:1.2 - dest=:1.105 reply_serial=2 After trying the approach above I tried to find something by monitoring dbus. I noticed that there is one interesting call made: method call sender=:1.74 - dest=com.nokia.HildonSVNotificationDaemon serial=73 path=/com/nokia/HildonSVNotificationDaemon; interface=com.nokia.HildonSVNotificationDaemon; member=StopEvent int32 1 I tried to call this method with dbus-send, but it had no effect either. Here's the dbus-send command I used: dbus-send --session --type=method_call --print-reply --dest=com.nokia.HildonSVNotificationDaemon /com/nokia/HildonSVNotificationDaemon com.nokia.HildonSVNotificationDaemon.StopEvent int32:1 Reply: method return sender=:1.21 - dest=:1.104 reply_serial=2 I have not found any other methods calls from the dbus-monitor logs and have not got any further ideas on what to try. Has anyone been successful at achieving this kind of behavior?

Re: How do I get my own phone number?
You can retrieve the phone number via a CUSD request *135#. /usr/bin/pnatd provides a tool for sending CUSD requests and AT commands in general. This may not be supported by all operators, though. Regards, Martin 2010/3/17, Cláudio Sampaio pat...@gmail.com: 2010/3/17 Frédéric Ledain frederic.led...@onmobile.com Is this a software or hardware limitation? My previous mobile phones showed me the number correctly when I inserted a new chip. AFAIK, no API gives the SIM phone number, as this is an information which belongs to the mobile operator. Actually, the correspondance IMSI - SIM phone number is made at mobile operator side. I think that anti-theft mecanism can securely be based on IMSI swap detection. Phone number doesn't add any valuable information in this context. Agreed, but try not to think as much as a software engineer and think as a simple user. Some people just forget their number - and it's useful if they can see it on the mobile, for telling other people. Some people carry a few SIMs around, and this information - the phone number - is useful to them. It might be that regular mobile phones use some kind of workaround to get this information - like, say, getting the destination number when they get a call - but nevertheless it is useful information that can be show to the user. So, really, no way to get it from the OS data?

Re: music player with .lrc support !
Hi, I have already written a LRC parser with support for enhanced LRC format in Python for MediaBox some time ago. Maybe you will find this helpful for a starting point. Personally, I think it's too small for a 3 month project, though. However getting LRC parsing into gstreamer or MAFW for use by the Nokia media player would be a fine challenge for three months, IMHO. But since the Nokia media player is closed source, it would be kinda hard to make it display lyrics. An alternative would be a widget similar to the TuneWiki widget, or a separate application for displaying the lyrics (which, IMHO, would be too small for a 3-month project, though).

Re: MeeGo
Hi, But packaging is a whole part of a good user experience. Bad packaging means *bad* user experience, trust me. I think this is the real problem about rpm here. Technically, I think rpm is superior to deb but Debian's apt is still unmatched as a package manager and the packagers do a better job (maybe because deb is easier to create?). I haven't used yum for years, so it might be better today, but back then (2004/2005), badly packaged stuff with bad dependencies and the utter slowness of yum drove me away from Redhat. I was involved in a project creating a Linux LiveCD builder based on Fedora for customer-customisable CDs. The user selects the applications she wants on the CD and the CD builder automatically resolves the package dependencies to build the CD. While in theory this idea was great and should easily be doable, we faced a lot of dependency-resolving problems with the original Fedora packages. Eeventually, we gave up on using yum for dependency-resolving and tried to implement our own algorithms (or should I say heuristics?) for resolving dependencies. rpm is very complex and allows for a lot of things that deb simply doesn't have. This makes it very hard to handle correctly. I have also ported Redhat's Anaconda installer to work with gentoo's emerge system for VidaLinux OS a few years ago. It's really hard stuff as rpm is so complex and badly documented. There are magic numbers and flags everywhere and this stuff is used. Redhat has a tradition of making simple things very complex (I would call it obfuscated open source, open source yes, but you rather don't dare touch it). Working with Redhat's code is a tedious task. OTOH, any maybe MeeGo will positively surprise me, rpm can be as simple and reliable as deb.

Re: FM RDS data
Hi, I would imagine that the signal strength can be read using V4L2 interface on /dev/radio0.

Great to hear this, I was thinking of trying something similar when I had some time. The FM transmitter also has a basic receiver built in (afair from the spec sheet), i.e. not the one that is built into the Bluetooth chip that is used to listen to the radio, which I imagine is designed for just such a usage (I think it just returns a signal level for each frequency, but I'd have to take another look at the sheet to be sure) does anyone know if we can access this at the moment?

The frequency bands the receiver is capable of are US/EUR (87.5 - 108.00 MHz) and Japan (don't remeber, but I think starts somewhere at 70 MHz).

Re: FM RDS data
Hi, the FM receiver's interface for RDS is exposed via sysfs. So any application can read RDS data from it. The frequency bands the receiver is capable of are US/EUR (87.5 - 108.00 MHz) and Japan (don't remeber, but I think starts somewhere at 70 MHz). A region switch in the driver (sysfs-Interface again but as root) switches between the frequency bands.

Re: which toolkit/framework is best for Game UI
If you're just displaying points, positions, and simple animations, then Gtk or Qt should be OK. Qt is the future of Maemo, anyway.

It's based on low-level Gdk but has all the work done needed for widgets and simple 2D animations. On the other hand, it's work in progress without a stable API.

Just to know. I see now this `ohmd` process in my 41-10. I did not get it, was this daemon improved or made worse in new firmware released lately? Better for known (pre-installed) applications, worse for unknown applications. The reason for this is that unknown applications have unknown resource usage so system policy treats them with more care. It's a bit of a chicken and egg problem. Changing the policy is slow iterative work requiring lots of testing that the policy change doesn't significantly worsen other use-cases in some situations (e.g. for things for which there are certain certification legal requirements). Developers can now experiment and report/discuss things which they would like policy to handle better (for certain classes of 3rd applications and their use-cases). I.e. in regards to 3rd party applications, the policies could be considered work-in-progress. Things that could potentially be done for 3rd party applications policy handling: - Default policy is improved in regards to unknown processes. It's yet unknown whether this can be done well enough without sacrificing the known functionality, that's why feedback is needed on the behavior of 3rd party application use-cases. - Applications themselves specify the required policy on install. This is extra work for apps, and requires extensive testing to guarantee that the policy they choose is good match for the application in all cases. (application doesn't leak or otherwise hog resources) - Some way for user to specify per-application policy.

Re: Why should it be so hard and should I even bother with Extras for fremantle?
Hi, it really looks wrong IMHO if stuff like socat, rootsh, or openssh turn up in the extras repository ready for end-users to be installed. extras should only contain applications that are safe for everyone to play around with. Stuff like this is meant for advanced users and developers. I think it would be best to have another official repository extras-advanced for these things, that comes preconfigured but deactivated on the device, with a big warning that apps in there are meant for advanced users who know what these tools are. Maybe we should open a brainstorm for separating the sharp knives from the toys. :) extras-advanced could have its own QA queue even. Or the QA decides whether something that passes QA is good for extras (safe for everyone) or extras-advanced (tools for advanced users). Maybe something like voting with thumbs up (end-user), thumbs up (advanced), and thumbs down? Any suggestions? Martin 2009/11/1, tz tho...@mich.com: I'm a power user and not the only one.

Way back when, I complained that half of what I wanted to install was invisible except under red pill mode, and after getting all the noise about not using it and explanations, for those utilities I thought were significant, I created versions in user/* because it is the only way they would be visible.

Re: QA process = bug fixing disincentive?
Hi, resetting Karma on a new version leads to one very bad issue, IMHO: Developers of packages with some Karma will hold back bugfix-updates until the unfixed version has reached extras. This should be avoided. Martin 2009/11/1, Henrik Hedberg henrik.hedb...@innologies.fi: igor.sto...@nokia.com wrote: I think the problem here is that some braindead system has been introduced, which doesn't account for the actual work being done. And what is the biggest mistake here is that the new system has been put into production before testing it at all. Someone just came up with an idea of crowd sourcing the QA and used random generator to set the parameters. Soon it was in real use before any experiences of its functionaly had got. I would have understood if the parameters had been really low (say, 1 day and 1 thumbs up) at the beginning, or there would have been a separate repository (say, extras-selection) to test this new functionality. The parameters could have been changed according to success of the system and in parallel with the amount of testers (and devices available). The sad contradiction here is that developers are expected to produce high quality outcomes and their results are put under QA, put the maemo.org processes and tools are not! Those should have been tested, for example, with a smaller group of developers before putting into production system. The maemo-extras testing marathon did amazing job. Thanks to everybody who participated! However, it cannot be a permanent way to overcome one of the biggest problems with the new system. I am not totally against the new system, and I do recognize the importance of quality assurance. I just hope that we can learn from the past and react rapidly. Please, do not refer to the better future and the possibility to have more users and testers later. Things should work now! Here are my suggestions now: 1) Fine tune the parameters: say, 5 days and 5 votes. These can be changed later when the system is working (has enough testers). 2) Change the system so that user packages that are depended by another user package are promoted automatically when the actual user package is promoted (like non-user packages are promoted currently). For example, when an user is testing Mauku, she is implicitely testing also the microfeed package [1]). 3) Find a way to overcome the limitations when an upgraded package is an important security fix. And here are my older suggestions [2], which, I think, are still valid: * Negative karma can be given _only_ if it based on the agreed QA requirements. (Testers are still giving karma based on their subjective thinking instead of QA requirements.) * The package page should have a link to a bug tracker and the link must be used! (Comments are stored into a wrong place currently. It is double effort for a developer to track the packages interface in addition to bugs.maemo.org.) * Negative karma can be given _only_ with a link to a bug tracker having a bug report about the show stopper. It may be either a new bug report written by the tester or an old open bug report just referred in the comment. * Negative karma is automatically removed when the related bug report is closed (fixed or other way resolved). (Currently, there is no way to remove the negative karma (thumbs down) if the bug is fixed. Please, note that the bug may be in the library code, and the bug in the package is thus actually fixed when the library is fixed. So, there would not be any need to update the application package every time.) BR, Henrik P.S. I do not necessarily see that more testers will make things easier and more workable. The more testers there are, the more subjective evaluations we will get. If one tester just do not like the graphics of an application he may give thumbs down, and even four other testers giving thumbs up are needed to fix that misjudgement. I really would like to see a discussion about the responsibilities of testers. Should there be a mechanism to give negative karma to testers who are not following the QA rules, or even way to ban them?

Re: The issue of version strings
Hi, hmm, what's so bad about a simple date for a version number? Ubuntu does it, (Open)Solaris does it, and I started doing it, too, because I found it less confusing than having version numbers such as e.g. 0.96.5. Martin 2009/10/29, Ryan Abel rabe...@gmail.com: One thing I think it might be worth working on is the user- friendliness of the version strings of packages in Extras. We want the Application manager to be as friendly and approachable for the average user as possible and long incomprehensible lines of alphanumerics are a surefire way to scare people off. ;) So, this is just my humble request that people be considerate of users when crafting their version strings and try to it reasonable.

Re: Considering /opt and MyDocs in your packages
Hi, It would be helpful if you could provide instructions on how to install apps directly into /opt without changing too much of the packaging stuff (remember, some package maintainers have to keep the Diablo version and maybe even a Linux Desktop version up to date as well, so anything that avoids big differences in packaging/code helps here). This depends on how you have setup your build-system. With GNU autotools, running configure.sh with --prefix=/opt/packagename would be a way, but you have to take care that the application icon, .desktop file and D-Bus service activation description still get into the rootfs. If you're using a simple Makefile instead if autotools then you have full control already. Relocating Python apps to /opt should be pretty simple. I do so by installing into /opt/packagename and putting a symlink to the executable module into /usr/bin/ (although this is not really required if the path in the D-Bus service activation description already points to /opt). If I need to find out about the installation path of my application, I read the __file__ variable which in every Python module points to the file path of that module file, so I know where to find my graphics and other data files, no matter where my application got installed. For C applications you may experience other problems such as not finding .so files. A way around this could be replacing the executable in /usr/bin with a shell script setting up the LD_LIBRARY_PATH variable for your app correctly. XDG_DATA_DIR can be specified by environment vatiables, too, IIRC. I think a subsection on this wiki page would be ideal: http://wiki.maemo.org/Opt_Problem I fully agree. Developers should be made aware that maemo-optify is not always the best way to move stuff to /opt. If I find some time this evening I'm going to make a start on the wiki page. There are some more caveats I stumpled upon, e.g. putting application graphics other than the app icon into /usr/share/icons results in a huge icon cache file. These issues should all be covered on the wiki page IMHO. Adding maemo-optify as build-depends and to debian/rules is just simpler and more straightforward than doing more intrusive changes. Yes, nothing against it. But developers should be made aware of the problems that may arise and that alternatives do exist. For porting stuff with hardcoded paths optify might still be the only feasible way, especially for developers without deep Linux experience.

Re: GStreamer playbin + MP3 playback on the N900
Hi, playbin2 works. playbin used to work too before having installed ogg-support, at least on a older firmware release (OS 38-x) it worked well until I installed ogg-support. The SDK documentation mentions to use playbin2, however, so breaking playbin shouldn't be too critical. But some gstreamer expert should be able explain why this breaks playbin.

Re: Considering /opt and MyDocs in your packages
Hi, in my opinion, maemo-optify shouldn't be hailed as the good-for-everyone savior to the rootfs space issue. I see it as a workaround for software that cannot be easily relocated to /opt. Optification symlinks take space on the rootfs too, so if you have a lot of them, you still waste several megabytes. Optification breaks package upgrading. File opening operations take longer as the system has to resolve a symlink first. Please don't get me wrong. optify is still useful and good to have, but everybody should bear in mind that it's only a workaround, and that relocating the software to /opt would be a much safer and more elegant solution. IMHO optify is OK for porting software from upstream, but if you write specifically for the N900, you should rather consider making your software easily relocatable eventually.

Re: Issues with Python and maemo-optify (was: Re: Maemo Summit /opt BOF notes...)
Hi, I'd suggest to not optify Python, but instead install the modules from /usr/lib/python to /opt, or ZIP it up. I think I've seen it already zipped up on some distribution, so this would be a way. Or compile the whole stuff with --prefix=/opt/python, and just put the links python and python2.5 into /usr/bin/. The site.py module could still be modified to support legacy modules that use /usr/ prefix. Optification looks like an ugly hack to me anyway, and the --prefix option should be used where possible.

What are the issues? • Standards. ◦ What about introducing a new 'mobile' Linux standard. • Repackaging. • Differences in flash performance. I'd like to raise one very important issue detected during our experiments with maemo-optifier and Python applications (including python's core packages, such as python2.5 and python2.5-minimal). Python in various places relies on paths returned by calls to readlink(). As some of you might know, the readlink() syscall dereferences symbolic links. One serious side-effect of optifying python2.5-minimal package is that: * /opt directories are added to sys.path * Any modules under /usr/lib/python2.5/site-packages are NOT found. * Byte-compiled files are put on /opt/maemo/ instead of the usual /usr/lib/... paths This happens because Python uses the full dereferenced path to /usr/bin/python2.5 (as returned by readlink()) to detect the module path. Therefore it only sees the modules under /opt/maemo, not the ones under /usr/lib/... (unless you explicitely set PYTHONPATH) Another issue is that even if python2.5 is not optified, any Python application which has its main script optified will not be able to import its own modules. See this experiment (running on a desktop): $ echo 'import testopt' main.py $ echo 'print hello' testopt.py $ python main.py hello The test case works just fine. Now let's optify it: $ rm testopt.pyc $ mkdir opt $ mv main.py opt/ $ ln -s opt/main.py . $ python main.py Traceback (most recent call last): File main.py, line 1, in module import testopt ImportError: No module named testopt $ ls -lR .: total 8 lrwxrwxrwx 1 andgomes andgomes 11 2009-10-13 16:05 main.py - opt/main.py drwxr-xr-x 2 andgomes andgomes 4096 2009-10-13 16:06 opt -rw-r--r-- 1 andgomes andgomes 14 2009-10-13 16:03 testopt.py ./opt: total 4 -rw-r--r-- 1 andgomes andgomes 15 2009-10-13 16:06 main.py As you can see, the testopt module was not found even though it is on the same directory as the main.py symlink. This happens because Python's notion of current directory is based on the value returned by the readlink(main.py, ...) syscall, which in this case is /tmp/opt/main.py. Therefore, python2.5 looks into /tmp/opt/ for the testopt.py, but does not find it. Of course, we can modify python2.5 so that it does not call readlink() on the main script, but for sure it was put there for some reason, and can create even more bugs. Besides, it can cause some subtle bugs, such as modules with the same name but in different directories being imported by mistake, and causing random exceptions. Therefore, we would like to ask the community how to better approach this problem. For sure the PyMaemo packages as is occupy too much space to be entirely on the root partition of the current size, so we need a solution to reduce the baseline Python size. Here are the options I see (in no specific order): 1) hack Python to not rely on paths returned by readlink() 2) Install Python properly under /opt by modifying debian rules (e.g. using --prefix etc.) and do not run maemo-optify for any python applications. 3) Work hard to reduce Python footprint Some remarks of my own: 1) looks dangerous, can create even more bugs than fixing them 2) Should work just fine, as long as ALL Python applications/modules also install under /opt. Note that creating symlinks back to /usr/... will NOT work, for the same reasons as maemo-optify currently does not work for Python. Has implications for all those Python packages, and will need special handling to make packages work for earlier Maemo releases. 3) Looks the best solution IMHO, but takes time and is not guaranteed to have big gains. Finally, I really like (3) best, but I'm afraid it is not a short term solution. We will do it anyway in the following releases, and we be believe we can achieve great gains (although it is hard to tell whether this good is good enough). Comments, suggestions are welcome! PS: we are about to make a release candidate for PyMaemo and we would love to see it already installed under /opt to reduce root partition footprint in short term, but given the various problems we had running it locally, we will probably have to postpone it

Re: Community widgets for Fremantle
Hi, yes, the colorwheel would have to be finger-friendly. This is quite difficult with a wheel. I have thought a bit about it and found another hopefully user-friendly alternative. I think that HSV sliders are more comprehensible than RGB for normal people. The H slider could show the color range in the backgroud, so that the user sees where the colors are. The V slider could then show the gradient for that color, and the S slider the saturation. Don't get me wrong, RGB is fine and this is what I prefer, but it's not obvious to use for a regular user, so we need some alternative way of finding colors.

Re: Considering /opt and MyDocs in your packages
Hi, I don't think /opt/package is a bad idea, and I wouldn't call it a hack. On other Unices, like Solaris, 3rd party software usually goes to /opt. In fact, by default, /usr is write-protected in virtual containers (mounted read-only from the host system). The good thing IMHO about /opt is that all stuff resides in one place, not being scattered all across the filesystem. When looking at Solaris, you can find directories like lib and bin inside /opt/package/. This way it's also possible for programs to bring in libraries that would otherwise break or mess up the root system. LD_LIBRARY_PATH, etc. can be setup by the start scripts of the programs accordingly. I'm all for keeping the root system clean of 3rd party stuff.

Re: Playbin volume bug for OGG and WMA playback
Hi, this is very interesting. Thanks for your investigation and detailed description. I have always wondered why I get distorted sound with Ogg and gstreamer on Maemo. Now it makes sense. Thanks a lot, Martin 2009/6/10, Nick Nobody m...@nikosapi.org: This has been bugging me for quite some time and I think I've finally gotten to the bottom of it. In this message I present my (limited) understanding of how gstreamer works, what this annoying bug is, potentially why this bug occurs and perhaps how to fix it. Lets get on with it. There are several ways that audio gets played through gstreamer, the audio can either be decoded on the device's processor or it can be offloaded to one of a few different hardware decoders (DSPs). Gstreamer's playbin provides a very easy way for the developer to not have to worry about writing pipelines for every possible type of audio that can be played back by their application. For MP3 and AAC audio, gstreamer uses hardware decoding provided by dspmp3sink and dspaacsink respectively. OGG and WMA audio must first be decoded to PCM (decoderbin takes care of this nicely) and then get passed to dsppcmsink. On maemo, the audio sinks (dspmp3sink, dspaacsink, and dsppcmsink) all have their own volume property (an integer between 0 and 2^16) and another property named fvolume which seems to simply be volume/2^16 (a float between 0 and 1). Either of these can be set, they accomplish the same goal; controlling the volume level. Gstreamer also provides a nice volume control element that you can add in a pipeline to presumably control the volume before it gets to the audio sink in the event that the audio sink doesn't have a volume property. The documentation says that the volume control element can take a value from 0 to 10 but during my testing it seems that anything over 1 distorts. So in reality you'll only be using it from 0 to 1. The Problem. If you create a pipeline using playbin to playback an ogg or wma file, you end up with a volume control element stuck right before dsppcmsink (see image #1). In this case playbin's volume property is connected to both the volume control element and the dsppcmsink fvolume property. This is were it gets weird, when you set the volume property of the playbin, the volume control element gets set to that exact number BUT the dsppcmsink's fvolume property gets set to one tenth of that number. Big deal, right? Wrong. This means that you can only set the output volume to about 10% before it begins to distort. For example, if I set the playbin's volume property to 3 (referring again to image #1), the volume control element gets set to 3 (we have distortion at this level) and the dsppcmsink's fvolume property is set to 0.3. The maximum value we can set the playbin's volume property is 1 (instead of 10, like when playing mp3s), anything else sounds bad. The Solution. There are two ways I can think of to solve this problem. Make the volume control element and the dsppcmsink share the same volume property or remove the volume control element entirely for playbins. I just don't really know how to go about fixing it... I suspect this issue has something to do with the way dsp sinks work on maemo's gstreamer. When using a dspmp3sink or a dspaacsink via a playbin, the volume property is a number between 0 and 10 which gets divided by 10 and used as the sink's fvolume value (see image #2). Could it be that someone simply forgot to divide by 10 in the volume control element code? Here are some gstreamer pipelines to help you experiment with this problem yourself (use these on your NIT). The following two pipelines sound exactly alike (very distorted), the first using playbin and the second using decodebin, a volume control element and dsppcmsink. The second is essentially the same as what playbin creates, which is wrong. gst-launch-0.10 playbin uri=http://tinyurl.com/524rwv volume=6 gst-launch-0.10 gnomevfssrc location=http://tinyurl.com/524rwv \ ! decodebin ! volume volume=6 ! dsppcmsink fvolume=0.6 Now if we change the volume element's volume setting from 6 to 0.6, there's no distortion: gst-launch-0.10 gnomevfssrc location=http://tinyurl.com/524rwv \ ! decodebin ! volume volume=0.6 ! dsppcmsink fvolume=0.6 These images were generated on an n810 running Maemo 4.1 with the ogg-support 0.9 and gstreamer version 0.10.22 (the version that comes with Maemo isn't able to generate images of pipelines). Image #1 (OGG file, playbin, volume=3): http://imgur.com/H1Uiy.png Image #2 (MP3 file, playbin, volume=3): http://imgur.com/oEB4Y.png I'm pretty sure this is a bug, but if not please let me know what I'm doing wrong here. Or perhaps someone could explain how Nokia's media player handles volume or pipeline creation since it doesn't seem to experience this bug. It would be a shame to have to force the application developer to work around this problem by either

Re: fremantle, clutter and the YUV overlay
Hi Gary, if you're using Xv for accessing the YUV overlay, then this should work well with Fremantle, too. I suppose that Fremantle uses EXA acceleration in the X server, so that YUV overlay will even be integrated into the compositing process, so that you can e.g. have an Xv overlay shining through a translucent window. Somebody with more insight into Fremantle please correct me if I'm wrong. Cheers, Martin 2009/4/2, gary liquid liq...@gmail.com: hi, Most folks will know I've been mad enough to know I have created the liqbase ui in the YUV overlay for the n8x0 devices. I have not been able to get the fremantle SDK up and running smoothly and am under the impression the emulation does not support YUV mode. I would like to know how well liqbase (and other yuv apps) will run when used in the composited clutter+opengl system. During my examination of this problem I discovered an excellent overview which includes video of it working, but whether that directly translates to the new Fremantle NXXX system I am not sure. http://www.mdk.org.pl/2007/11/17/gl-colorspace-conversions I will follow up with an x11+xv test app if required.

Re: No key events for virtual keyboard?
Hi, the GTK editing widgets in maemo are modified to receive the key codes (or rather UTF-8 strings) from the VKB. The VKB does not send normal X key events (except for Enter and Backspace). The GTK input widgets don't emit a key-event or changed-event per VKB key. You can connect to the commit signal of the GTKIMMulticontext to receive key by key. Here's an example (in Python, calling the C-libraries directly, so it should be portable almost 1:1): https://garage.maemo.org/plugins/scmsvn/viewcvs.php/trunk/utils/hildon_input_method.py?revision=556root=mediaboxview=markup (replace hash(win.window) with the pointer to your GdkWindow in C) You can open the VKB for your application's toplevel window this way and receive all key events. However, be warned that if your application relies on GDK_POINTER_MOTION_HINT_MASK, the VKB will break pointer motion event detection badly! If you don't have to rely on the hint mask, it's all OK. Regards, Martin 2009/1/9, Eero Tamminen eero.tammi...@nokia.com: Hi, ext Till Harbaum / Lists wrote: i have just ported tetrinet for linux to maemo. You can get this from the extras repository. While this works well on the n810's physical keyboard it doesn't work with the virtual keyboard (neither on my n800 running chinock nor an the n810 running diablo). The problem is that all keyboard handling is being done by the original tetrinet for linux code and my maemo gui just forwards all key presses there and updates the gui on the returning function calls from the original code. Thus i have installed a key_press_event handler which then feeds all key presses into the tetrinet engine. Unfortunately the virtual keyboard doesn't generate events. Or to be precise: It does, but for some reason only for the Enter key. How comes? Can i somehow get access to all key presses from the virtual keyboard? VKBD sends the events as X messages to the Gtk editing widget (i.e. something having Gtk IM context) that has the focus. Apparently it still synthetizes couple of keys (apparently Enter and maybe Backspace) as normal X key events, but that doesn't work for all keys (X key events cannot represent all unicode characters). If you ever tried mtetrinet on the n800 or on the n810 with the virtual keyboard you'll find that you can in fact enter things into the entry fields. But these don't enter my keyboard routine but instead magically appear directly in the entry field. This means that the tetrinet engine underneath never saw these key presses and thus ignores them even though they show up in the entry. Thus you e.g. can't type anything in the partyline which limits the functionality pretty much. - Eero ___ maemo-developers mailing list maemo-developers@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-developers ___ maemo-developers mailing list maemo-developers@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-developers

Re: language and library advice, please.
Hi, 2008/11/11, Hendrik Boom [EMAIL PROTECTED]: It has been suggested that python would be an appropriate language, because it's available both on the n800 and Debian, and is probably fairly compatible between them. I fully agree. It's very compatible between n800 and Debian. (a) What library(ies) should I be using for user-interfacing. Are they reasonably compatible between Debian and maemo? Take GTK. It's the native toolkit library of maemo and the GNOME desktop (or XFCE) on Debian. (b) Are there a ready-made text-editing widget I can start with? The complete structured text will contain a lot of reasonably small sub-texts that can be edited conventionally, at least in the prototype. So I'd like to prototyoe it with a ready-made editor handling the smaller pieces of text (currently the pargest such piece is about 25K) ans saving the structural part for the regular UI library. GtkTextArea might the widget you're looking for. (c) Any problems you can already see coming, based on experience with these tools? (Here I'm not looking for generic software-engineering advice, but I'd like to know if there are any specific gotchas involving python or the recommended libraries. I've been programming for decades, but not in python). Toplevel window handling is a bit different between Debian and maemo. But code can be written to use the appropriate way on each system.

Re: how to set gtk widget translucent
Hi, there are different sorts of GTK widgets. Some widgets simply draw on their parent window, and some widgets (those that can receive user events) draw on their own low-level window. The widgets with their own windows (e.g. GtkButton, GtkEntry) are opaque and completely hide what's behind. However, you can punch holes into their shape (gtk_widget_shape_combine_mask) to reveal what's behind. Alpha blending is not possible though. So, this wouldn't work with your findbar idea. Windowless widgets (e,g, GtkImage, GtkLabel) can be composed on top of each other and support alpha blending just fine. Your findbar needs text input, so it's not a windowless window. On modern Linux desktops (but not on the current maemo) you can also use an RGBA colorspace to draw onto the window. The composition manager then blends the window according to the alpha pixel values. This would be the perfect solution for your findbar, as the bar could be implemented as another toplevel window layered above your application window. However, you can't do this on maemo. I suggest looking into GtkStyle to change the background image of the GtkEntry widget. You can grab the screen contents, dim it, and paste into the entry widget. This would create the illusion of translucency. Regards, Martin 2008/10/27, Jun Xu [EMAIL PROTECTED]: Hi, All, I want to add a gtk widget on top of another gtk widget, and then set Alpha value to the widget above, make it translucent. for example, I want to add a translucent findbar on a window.

Hi, 2008/2/7, Al Khadra [EMAIL PROTECTED]: 1- When the battery is fully charged the Tablet will not only display the regular message but will also BEEP. This way you do not have to keep checking whether it's full or not yet. You will hear the beep. As you know overcharging kills the battery. Overcharging is not possible, unless your battery is broken and has to be replaced anyway. There is a circuit built into every Li-Ion battery to prevent overcharging. But if the charger is plugged in, it keeps topping the battery at 100%. Li-Ion batteries lose capacity over time, and the rate is dependent on the temperature and fill level. At 100% fill level, it will lose capacity faster than at 40% fill level (which is best for the battery). Li-Ion have no memory effect, but they age. 2- Is it possible to make an application that will turn the Tablet into Bluetooth Speakers using the A2DP profile? For instance, you can stream audio from the Motorola DC800 gateway right into the Tablet. This is a question for developers who can tell if this is feasible or not. This should be possible, but since I'm not into bluetooth, I can't say for sure.

Re: python2.5 - unnecessary multiple processes forked

Re: python2.5 - unnecessary multiple processes forked
Especially make use of gc.collect() after you have worked with gdk.Pixbuf objects. They won't free their memory otherwise. It's a good habit to free unused Pixbufs with del and run the garbage collector afterwards. And be aware that if a class overrides the __del__ method (some sort of destructor), it won't be freed by the garbage collector at all. Cheers, Martin 2007/12/31, Alex Iliadis [EMAIL PROTECTED]: I recommend using the garbage collector module manually to override the defaults. Python for some reason doesn't reclaim memory fast. So if you put in your code: import gc gc.collect() (at the right spots, probably after the file chooser dialog and after some memory intensive tasks). You should notice a lot of memory being free'd up. -Alex On Sunday 30 December 2007 05:20:34 pm Jayesh Salvi wrote: Hi, I am porting a pygtk application to maemo.

So I ran my application using pdb and narrowed down to a code segment that was leading to multiple instances of the process. It turned out that when I call run() on hildon.fileChooserDialog object, the dialog opens and at that moment in the top I see 4 more instances being forked. I fail to understand this behavior. I replaced the hildon widgets by pure gtk widgets and I see similar behavior, except that 2 more instances get forked.

Re: service is temporarily unavailable
Hi, This is not an official explanation, but it is what I think is happening... Apparently, the maemo server was taken down for maintenance and stupid Akamai cached this state. Now that the maemo server is back online, Akamai still serves the error pages. This could be because the maemo error page did not return an HTTP error code, but looks like a valid HTML page (status code 200). If this is the case, how should Akamai know that it's caching bogus? If you access maemo.org with any prefix other than the Akamai-cached repository, you can circumvent the Akamai cache and get to the real server.

Re: Video decode capability of N810
Hi, the N810 cannot handle videos in VGA resolution very well. At least on the N800 the video bandwidth is rather limited (in contrast to the Nokia 770) and I assume that the video hardware on the N810 is the same. Video decoding, however, works fine with lower resolutions such as QGA. ffmpeg runs fine on the N810, but is not installed there by default. The API for DSP accelerated video decoding on the N810 is gstreamer ( http://gstreamer.freedesktop.org), which is opensource software. Some gstreamer plugins on the N810 are closed source, though. Without using gstreamer, you can get very good video playback with mplayer ( http://mplayer.garage.maemo.org). By using mplayer's slave mode, you can embed the player into your own applications, like kmplayer, Kagu, and MediaBox do. Cheers, Martin 2007/12/8, g c [EMAIL PROTECTED]: Can someone tell me what frame rate and screen resolutions the N810 can decode? Specifically, can it handle MPEG4 at 30fps at VGA resolution?

Re: Re: Android Vs. Maemo
Hi, since Android makes heavy use of Java and OpenGL, there is a problem with the current maemo to support it. While the N8x0 hardware contains a 3D graphics chip and Java acceleration, both are not yet accessible on the maemo platform. But maybe Nokia is silently working on these 2 features... who knows... With Java and OpenGL available, there should be no reason for Google and Nokia not to built an Android compatibility layer for maemo devices. Since Google is already involved in maemo with GoogleTalk and being the default search engine, it wouldn't sound too far-fetched if both companies worked together on Android as well.

Hi, I have noticed that when you release the button (finger, stylus, etc.), Gtk emits a motion-notify event with the same pointer coordinates again.

Gtk on my desktop computer behaves differently, so maybe this is a Hildon or touchscreen issue.

The code is available under LGPL as a garage project ( http://pyfmradio.garage.maemo.org) and I have also created a wiki page about the backgrounds (https://maemo.org/community/wiki/fmradioprogramming/). Maybe someone will find this useful. I'm gonna use this code to add FM radio functionality to my new media center (https://mediabox.garage.maemo.org). Cheers, Martin ___ maemo-developers mailing list maemo-developers@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-developers
Re: How to setup ad-hoc wireless network N770 PC Windows XP ? (pls don't delete)
Hi, please note that the ifconfig commands are not to be run on the tablet, but on the PC. On Windows XP, you would instead setup an Ad-Hoc connection by using some GUI tool. The Nokia tablets support Ad-Hoc mode out of the box. You just have to select Ad-Hoc mode for the connection in the connection settings. Remember to select Ad-Hoc mode on the PC side as well. Now if the SSIDs are the same, you should get a connection. I usually use static IPs for the PC and tablet in this mode. Cheers, Martin 2007/11/2, Darius Jack [EMAIL PROTECTED]: Thanks Michael, if you mean ap as access point so I don't have any ap as I set up ad-hoc wireless network ap-free It already works if I assign static IP addresses both on Nokia and PC running TVersity server. Unfortunately I can't Opera web browser or Media Streamer as each one saves established ad-hoc wireless network invoking maemo network connection utility hanging maemo up , crashing and rebooting it. As I see neither Opera web browser not Media Streamer can connect to TVersity over the already established ad-hoc network. TVersity can be run locally on PC as http://localhost:41952/. So the problem is not very complicated but how can I force networked applications like Opera web browser or Media Streamer not to invoke maemo network connection utility and use the established ad-hoc wireless. I set both IP addresses as static and SMP monitor can read maemo IP address. Pls remember hardware configuration. No access point, no router. Peer-to-peer ad-hoc wireless network only. No DHCP assigned IP addresses, static IP addresses only. Any chance to have it working one day ? Thanks.

[maemo-developers] Can't create application on test.maemo.org
Hi, I have some problem with the new test.maemo.org application site. After registering with my garage account, I created an application, filled out the form, uploaded a screenshot, and hit the save button. Then the site crashes with: Notice: Array to string conversion in /usr/share/php/HTML/QuickForm/Rule/Required.php on line 39 Fatal error: GObject missing or incorrectly initialized in /usr/share/php/midcom/lib/midcom/core/privilege.php on line 906 I tried this twice and always got the same result... :( Regards, Martin ___ maemo-developers mailing list maemo-developers@maemo.org https://maemo.org/mailman/listinfo/maemo-developers

Re: [maemo-developers] Discussion of a possible project - offline calendar project
Hi, Mathias Uebelacker schrieb: Well here some thoughts from my project sheet: - which language should be used ( C, Python...) - how should the data stored (database, file ...) - should the application interacts with osso applications (Adressbook, email) - limitation of the screen size (N770) - look and feel like the original ?? - exchange with the google calendar (import/export) - language files (for each user his or her language) - and and and This sounds really interesting. I know that there are already applications like dates or GPE-calendar for the N770 but both don't fit my needs. Since my idea was to write some sort of PIM suite specially for the 770 in the near future, maybe we should join efforts. I have written software for the 770 in C (Ogg Vorbis Player) and Python (Obscura Photo Manager) and have to say that Python wins for big applications, IMHO. Development is much faster and the code usually more clear and stable than with C. So I'd vote for Python. One of my first opensource projects was the desktop calendar gDeskCal (http://www.pycage.de/#gdeskcal), so I have some experience with reading iCalendar files. If there some developer which will start these project with me let me know. If we can build a Team i will ask the garage-team to host that project so that we ca n start the work. Sure, why not? :) Regards, Martin ___ maemo-developers mailing list maemo-developers@maemo.org https://maemo.org/mailman/listinfo/maemo-developers
