I don't know much about APT, maybe something of this kind exists already? It doesn't exist yet, but that is exactly the plan we have for Harmattan. The first little (quite untested) building block is deb-exec. The apt-get in Harmattan now understands sources.list entries of the form deb-exec PROG and it will run PROG --packages to get the Packages file (and PROG --get FILE to eventually download a specific package file). The idea is that PROG would use a little database of its own to determine what should be downloaded. This database is maintained by a new 'discovery client' that uses whatever protocol it wants to 'discover' new interesting packages. Code is here: http://maemo.gitorious.org/maemo-pkg/apt/commits/maemo The current plan is to make a package of this that can be cleanly installed on Fremantle next to Fremantle's native apt version. The next building block will be to allow apt to temporarily use small Packages files without having to recreate the whole binary cache. This would be used by the discovery client to efficiently check dependencies etc for packages that apt doesn't yet know about. ___ maemo-developers mailing list maemo-developers@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-developers
How to enable mouse icon to be visible on N900?
Hi, I searched solutions but failed to enable it. Even worse, I found No mouse cursor available yet. The trick from alpha version to make mouse cursor visible doesn't work any more in Maemo5 final version (some applications like tuxpaint draw a mouse cursor and can be started from the command line) on http://omappedia.org/wiki/Maemo_Getting_Started.

MADDE and Qt4.6
Hi, I know that MADDE is not official supported. I have try to use it with Qt4.6 and Qt Creator, I have used versions 1.3.80 (as in http://wiki.maemo.org/MADDE/QtCreator_integration_for_windows) and 1.3.81 and 2.0.0alpha1. Qt4.6 was taked from http://chaos.troll.no/~harald/MADDE. I have try on Linux and Windows with the same result in QtCreator: The Qt Version has no toolchain. Qt4.5.3 from MADDE works well with QTCreator (any version, any platform). Any sugestions how to make it work?

[fremantle] HTML rendering inside applications
Hi, suppose that I have some HTML (in a file or in memory) and I want my application to display it as a static bitmap. How can this be done? Is there some browser API that I can call, and which would return me an image of the page. Ideally, the input data should be the HTML, a desired width (in pixels), a zoom level (or character size); the output would be a bitmap, either in memory or as a file path. Any suggestions?

If we DO accept that, though, some more grep magic reveals that of the 7726 total packages in extras-devel, 2892 are unique, so almost two-thirds are duplicates. The extras-(devel?)-history is a good idea also in the way that it falls in line with the notion that the source packages of every version should be preserved (even if we eventually delete the binaries from extras-devel). Another sideeffect would be that package operations would be drastically sped up (everyone who uses extras-devel knows that the busy indicator goes around quite a few times on every operation, mostly as a result of the sheer size/number of package descriptions).

The only decision it makes is between installing that candidate version, keeping the version you have already installed, or removing the package altogether. It will not reconsider which version should be the candidate based on dependencies between packages. Old versions are only useful with apt when you explicitly do things like apt-get install libfoo=1.23-5 This _is_ useful, but only during debugging. ___ maemo-developers mailing list maemo-developers@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-developers

I'm talking about a scenario when the application has an 'older than' dependency (often in combination with '|'), which apt (and HAM) *will* honour. So if app A has a libfoo 2.0 dep, app B has libfoo 1.0, and there is currently a libfoo 1.5 in the repo, both A and B are installable. If you upload libfoo 2.5, however, and 1.5 gets automatically archived, app A is no longer installable (even though it could have been if you kept both versions of libfoo). Not a common case, I admit, just saying one has to be careful when removing packages from repos.

Re: Extras-testing improvements
- Original message - On Tuesday 09 of March 2010, Graham Cobb wrote: The community needs a place where **every** app passes through a very basic QA to try to make sure it is safe and it is then available. That is what Extras is. IMHO, that's not extras. Currently extras is the elite of maemo's software. Explaining: Asking for 10 votes for each version of each application is something that I call paranoia in software development. For example: I've a fully optified app that works without problem, but will never be promoted to extras because there are not enough developers with interest in it (more specifically: women). That is a problem that needs a solution. The niche products need to reach extras too. But the audience of extras is very different and there would be interested audience if it were there. What's the reasoning of asking 10 people to do the same thing? This is now popularity contest instead of a QA process. Popular apps among developers (techie guys) advance. Non-popular apps wait. Assuming that the QA process is a serious process, asking 10 people to do the exact same thing isn't serious. If those ten people are all doing the same thing I would be surprised. Ten people, ten different test styles. If the check is performed correctly, you should need at most 2 persons. If the check if not performed correctly then 10 is not enough. I suggest you take a look at debian's method. Having a kind of maemo- developers that act responsibly, certifying applications would be a good solution. Currently the vote of a person without any programming abilities is the same with a person's that can program and have performed the checks. The best solution IMHO would be for Nokia to have 1 or 2 people to do this job responsibly instead of relying on statistical methods. Now you are mixing Nokia with the Community. The two are different. The reasoning behind the number of people is that people behave differently and having just one person go through the app will not cover the use cases of any app. Also it would leave the system wide open for gaming it. I have no idea what is the optimal number of people, but it is not 1-2. That would also be very good support of the community efforts and would boost software development. After all, the applications in extras is a big part of the (future) value of maemo/meego. Could you elaborate? How does Nokia testers boost development? I can't follow that logic, but I agree that having good quality open source software is important.

Google Summer of Code Proposal
Hello everyone. I am interested in developing for Maemo under Google's Summer of Code program and the project 'Answering Machine/Call Rejector' on the Ideas page interests me particularly. I have been using a Nokia phone ever since I can remember and I used to love the 'Screened Number' features the classic Nokia phones allowed. However, as I kept upgrading my phone, I noticed that such a feature was never there (Nokia E63 now), even on the high-end phones. The need for a blacklisting software led me to some commercial S60 software (I won't mention the names though). I find it odd saying, but I have expertise in this field! I have been using such software for two - three years now on a variety of S60 phones, and I know what features should be there. Specifically, I feel the need for : 1. Blacklist - Calls you don't want to attend at all. 2. Whitelist - This feature is not usually found in many commercial software also, but it is required. There are many-a-times you want to receive calls only from a few numbers and automatically reject the other ones. If you blacklist some numbers, that works only for the contacts that are you in your phone book. Otherwise for unknown numbers, the phone does alert you. When you want to attend calls only from a few numbers, then Blacklisted numbers don't do justice. 3. Support for text messages screening - Again, whitelist and blacklist. I think the blacklist/ whitelist for voice calls should be different from text messages. This again I base on personal experience. 4. Time based call rejecting - Set it up and forget! If any developer is interested in mentoring this, please let me know. I think this is a must have feature. Coupled with the answering machine function, it can work out wonderfully. -- Sukhbir ___ maemo-developers mailing list maemo-developers@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-developers
