N800 Power cycles
Hello, my N800 crashed after running navit. During the reboot, the blue bar completed, then it paused sometime and it rebooted again. This now cycles so that the N800 is doing nothing else than power cycling. Is there a better way to fix that than reflashing the device? Is there a way to find out what the root cause of the problem is? Can RD mode help to be more verbose during the boot process?

[GSoC 09]Semantic-Based Context-aware Personalized News reader System for Maemo
Hello, all: This is my first report for GSoC 09 project. In the previous two weeks, I have been working on the semantic module, and finished the basic function of it and now stil working on test script, modifing the previous code and trying to integrate the module with gpodder. Before talking much more about problems in my project, I want to re-introduce the concept of this module to make things clear . This module is used to annotate description of each item(like one episode in one channel) by OpenCalais, then generate a item profile. In the item profile, it has three data fields.they are type,name,and relevancescore. The type is the so-called parent class of the name, and the relevancescore is computed by OpenCalais webservice.After it, user profile which represents user's interest would be compared with the item profile, then a recommendation score will be given to the item. The presentation module of a podcast or rss reader application then can mark an item as a recommendation one according to the score. Well, I think now you may have known what the semantic module is. Then I want to talk about some problems in my project. The first one is the OpenCalais has a weak capability to annotate content. It just can gives one-level semantic annotation , but which in my mind, it should be a N-level semantic annotation. If we have N-level annotation,then we can not only know Obama is a person, but know Obama is a politician. The weak one-level annotation make the recommendation algorithm relatively be meaningless. The second one is the response time. I have tried to use the semantic module to process the Linux Outlaws channel's episodes, but I think it takes too long time than expected to do annotation on the N800. So I'm so worried about whether uses can accept this. The third one is until now, the module just simply uses a copy of item profile to be the user profile to do the recommendation score computation. It's not good for test, so I'm now working on adding a new class into the code then make users and developers can use xml file to specify the content in the user profile. I will submit a new version of code in the next three days maybe. I think until now there are just these three problems, and I will try fix them in next week. I'm now also working on writing a test script for semantic module and trying to integrate my module into gpodder then we can see the final effect of this semantic module. If you are interested in my project, then you can find much more information on http://garage.maemo.org/projects/newssprite. You can also check out the code on the svn repository. (I recommend you check out the code three days later just after I check new version code and test script in it). Any comments and suggestion are welcome.Thanks. -- --Feng GAO --School of Computer --Beijing University of Posts and Telecommunications ___ maemo-developers mailing list maemo-developers@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-developers

Upgrading with Application Manager [Fwd: Update conflict with Update All and dependencies]
Hello,
sorry, don't want to be annoying, but with another update of a software
i package for maemo this problem is still unsolved. In short: How do I
make the update with Application Manager possible of two packages that
depend on an exact version of a library package? I.e. package A version
x.y and package B x.y depend both on package C x.y , but Application
Manager refuses to update both at once (unlike what apt-get upgrade
would do).
Thanks
Stefan

Hello,
I am running across a strange thing with Application manager: Update
all does not seem to work like apt-get upgrade, instead it seems to
update one package after the other. This of course fails if multiple
packages depend on the same version of another package - all other
packages would have to be deinstalled first to be able to update one of
those packages.
I have two application packages that both depend on an exact version of
a library package. Now when I push updates of all three packages to
(extras-devel) repository, in the application manager I see the two
application packages as available updates. The problem is, if I want to
update one, it says Conflicting application packages and Conflict
with application packages: and the other application package with the
old version. While that may be expected behaviour, IMO a clear bug is
that Update all fails with the same - first it says Unable to update
xyz, Conflicting application packages. Continue installing? but if I
click yes, it complains with not being able to install the other package
again.
apt-get upgrade of course works correctly, updating all three at once
('apt-get install anki ankiqt' would work as well i guess). I can not
believe the Application manager to be so stupid on top of such a
powerful package and dependencies system as debian's. Maybe I got the
dependencies wrong?
To illustrate, the dependencies of the old version:
Package: ankiqt
Version: 0.9.9.7.6b-4
Depends: anki (= 0.9.9.7.6b-4), python2.5-qt4-svg
Package: ankimaemi
Version: 0.0.6-8
Depends: anki (= 0.9.9.7.6b-4)
Package: anki
Version: 0.9.9.7.6b-4
Depends: python2.5, python-sqlalchemy ( 0.5.0), python-simplejson (=
2.0.6)
And the new ones:
Package: ankiqt
Version: 0.9.9.7.9-2
Depends: anki (= 0.9.9.7.9-1), python2.5-qt4-svg
Package: ankimaemi
Version: 0.0.7-2
Depends: anki (= 0.9.9.7.9-1)
Package: anki
Version: 0.9.9.7.9-1
Depends: python2.5, python-sqlalchemy ( 0.5.0), python-simplejson (=
2.0.6)
Thanks for any hints how to solve this. I have not found any related
bugs in Settings and maintenance at bugs.maemo.org.

Re: N800 Power cycles
Henrik, thanks for the quick reply. Am Samstag, 6. Juni 2009 schrieben Sie: Rainer Dorsch kirjoitti 06.06.2009 21:02: Weired, after waiting a few hours and booting the N800 w/o a power cable, it booted again. When a power cable is connected, the device seems to be running the operating system in the background. Thus, simply switching the power off does not reboot the device in that case. If you need to cold boot the device, the power cable must be disconnected (and sometimes a battery also ;). HmmI was removing the battery several times (that was the only way to stop the power cycles). But when I inserted the battery again (sometimes after minutes) and plugged the power cable the N800 started immediately to boot. I am wondering what I would have done if my battery would have been empty and I could not boot w/o power cable.

Re: [GSoc 09] Barcode Scanner and shopping Assistant - report 1
Really sorry for the screw up there ... Hi all, The general idea of the project is an application that will scan barcode image and than search stores on web and local stores for prices , reviews etc .. As part of the project the first thing was to test out maemo-barcode toolkit . Sadly I was not able to run it on my SBOX . Although I did do some bug fixes on it . It still didn't seem to work. We also evaluated some other toolkits on SBOX and zbar seemed to run fine( http://zbar.sourceforge.net/) zbar gives us some of the features that we were looking for i.e 1. Almost the same speed of decoding for different types of barcode 2.1D(ean and upc) as well as 2d barcode scanning 3.Python bindings . So I have *recommended to use zbar *. If there is work required in terms of image quality perhaps it can be developed as a *seperate independent module using Image Magick or PIL* The second part of the project .. ie that of *price comparison* is to be done using server side scripts. As a beginning to this i have started adding code to get product title for a particular barcode. The reason to use product titles is because we would need to search many *heterogenous databases *and I think product titles would make the job easier in this regard . *Not all databases or systems provide the capability to search by upc or ean no. *Their are as far as i can see two methods for price comparison . This part we have decided should be done in a manner that it is easier for *merchants to add their feeds/database/other such stuff * For *web stores* we could *create a crawler using Yahoo Boss API *. Although I would wonder if it can be optimized in such a manner that it is even able to extract price information and reviews etc On the side of *local stores and feeds* - We could have our own specification for the feed .. but this might be too complicated for small local stores .. The problem with local stores and feeds would be that they would tend to be very heterogenous thus we require a search system that is flexible ... For this I think we should do a full text search(perhaps using pyLucene) on the databases/feeds we recieve but again question is can we optimize this kind of search to the level that we can get price info and reviews etc The next apart of course would be to write the client side for price comparison and UI P.S The ideas for price comparison are major thought waves that perhaps need to be orgainized and understood better. Also please add recommendations and other such input. Also although i have experimented a bit with BOSS i have no clue about pyLucene so please feel free to add warnings about the kind and load of work involved and *tutorials/links/projects *on the two topics .

I will run a script here to check python packages in Diablo that should fail to install in fremantle due to missing dependencies, and check which of these dependencies are related to PyMaemo packages. What were the results of this? Ok, the above looks like a comment of mine :). Actually I didn't finish this task yet. Once I have done it, I'll report the results here. Fantastico! :) Currently the state of python packages and their dependencies is confusing. It would be really great if you guys had a dependency tree, or some form of canonical list. Perhaps this page could get fleshed out a little? https://garage.maemo.org/plugins/wiki/index.php?PyMaemo%20Modulesid=40type=g Something like this? http://wiki.maemo.org/PyMaemo Yes. :-) - They didn't know the auto-builder would let a package go through to extras-devel with dependencies missing. I think the above two shows that the extras-devel system needs to be more documented/promoted ? Which packages got built without their dependencies? The autobuilder does not check for *runtime* dependencies, only *build time* ones. This is not a big issue (I think autobuilders from other distros do the same, but I'm not sure), as long as it is documented/promoted enough as Quim suggested. Build-time dependencies (i.e. build-depends) need to be there for that package to be built. But the Depends field in the control file should pull in those packages that are depended upon at runtime. - Some didn't know where the python-support (= 0.90.0) dependency actually came from. This I don't understand. Developers have to have all their dependencies in order to build the package locally, how would they not have all the depdencies? This can have a lot of reasons, one of them being that they simply don't have the extras-devel repository on their local sbox /etc/apt/sources.list. And if it is a runtime dependency problem, the build will finish ok, although the package will not be installable. If this is the case, it shows yet another QA issue: that the built packages might not have been tested for correct installation/removal. Yes - I agree. This is a quality control issue. The dependency chain needs to be managed smoothly for users since they should not have to deal with this. * python-mokoui : no idea which package is this. Jeremiah/Niels: can it be added the your automatic building task? This package has been sent to the fremantle autobuilder. I think the original maintainer has said that it should not be necessary anymore and that the package that broke because of it will/was fixed (if I remember correctly) It does not build in fremantle, at least right now. It is called libmokoui and I am going to try to get the errors fixed. Thanks for your complete and prompt response Anderson, I appreciate it.
