Have you ever dreamed of to ssh into your phone and install Gnome stuff with apt-get? Well at least some have and thus created OpenMoko but sadly they only managed to produce two prototypes with unusable software. Well you can still install android on them, but then you basically use Java instead of the traditional Linux software stack. This is also the “problem” which you get most of the current Android phones. Well of course apart from being locked in to google.

But there is hope! It seems like Nokia is finallay putting Maemo on a real phone. See this photo for the looks. In case you have missed the Maemo up to now: it is a Gnome based desktop for MID – just like Ubuntu MID, but better designed. And the best news is that it will use a Clutter based interface for the next release – just like Moblin. This makes Maemo look really slick.

Besides of the looks it uses all the Gnome internals which Ubuntu uses (at least Karmic): Telepathy for Messaging, Firefox as the browser an evolution based Mail client. I currently use it on my N800 and it is really great; want to try out Fennec instead of the pre-installed browser? One click automatically adds a new apt repository.

This probably reads like a straight advert, but I really waited for a phone like this.

As a sidenote: clutter seems to have quite a momentum this days: Moblin, Maemo, Gnome3 …

It has been a while already since I last ranted about the main programming language used for Gnome. Mostly because you are not forced to use it and so I did not. But recently there were some posts on Planet Gnome which reminded me how inherently broken the core of Gnome is. I mean we have all this nice libraries like GTK, Glib etc. and they are easy to use and generally well designed, but when you want to hack on the core of them you have to use C.

I understand that back then when the Gnome project started C++ was in a very high flux with uncertain design bad compilers and so Gnome was written in C instead.

But looking at C++ today especially at the modernizations coming with C++0x (which are mostly already available in gcc4.4 btw.) it is really hard to understand why C is still used.

Just look at the linked examples; since C does not provide any build-in concept of iterators and the language is not flexible enough to provide them as library even experienced Glib developers iterate over lists in O(2^n) instead in O(n). How braindead is that? Instead of re-using the object concept and the syntactic sugar provided by C++ we are re-inventing the wheel with Glib. Luckily the community lately noticed that the syntax using Glib is so fucked up so you are not being productive any more. And what was decided as a solution? Reinvent the compiler by writing Vala – WTF?? There is already a compiled language which is compatible with our old code and which looks almost identical to vala; C++.

And I am not the only one who thinks that C++ is generally preferable over C. Here is a presentation discussing writing GCC in C++ which eventually happened. And these people are writing compilers so they should know if the language switch is worth it…

I thought the great thing about OSS is that you dont have to reinvent the wheel, but simply can use the well tested ones. Sometimes I really question the sanity of the Gnome developers…

After the native theming that thunderbird3 will have, another issue with GNOME integration has been cleared out. When you used Thunderbird/ Lightning as your calendar the rest of the GNOME desktop would not know about your dates. So for instance the gnome-clock-applet would not show them.

But now there is a add-on available which pushes the data from Thunderbird to EDS(Evolution Data Server), so that they will be displayed in th gnome-clock-applet.

Make sure that you have python-gnome2-desktop and evolution-data-server installed 🙂

Now that Google Chrome is finally coming to Linux we have a simple and fast Webkit browser. It is also opensource and uses GTK. So where is the need for Epiphany? One may say that it might better integrate with the rest of GNOME, but currently Empiphany is about just as integrated as Chrome and I guess it would be easier integrating Chrome wih GNOME than making Epiphany a good browser…

I just uploaded a new version of YouAmp to the YouAmp PPA. Note that this is the desktop version and thus will not work on the N8x0 devices. Actually there wont be any updates for the Maemo version until Frementale, since the codebase currently already depends on some of its features. (which are already available in Ubuntu 9.04)

You may wonder where the jump from 0.5.4 to 0.5.10 comes from – actually there were releases in between, but since it were only minor feature additions, I did not announce them explicitly.

So here are the new features from 0.5.4:

• show notify-osd compatible notifications on song change
• support multimedia keys
• better status icon (minimise animations, tooltip)
• gapless playback
• Drag and Drop support (reordering, copy to from/to directory)
• uses Tracker for Indexing

And the best news is that playlists are half way done already 🙂

As you surley know linux is crap, cobbled together by some amateurs. Well at least many trolls on the internet know. Sounds like prejudice and intentional offense, right?

Well, you probably heard of Jörg Schilling and the desaster with cdrtools – if not you can read it up here. The problem back then was that he (the author of cdrtools) changed the license to an GPL incompatible one ignoring the objections of the users.

And here comes the next one; Debian just decided to replace glibc by eglibc, because the maintainer of glibc, Ulrich Drepper, is.. lets say very uncooperative when it comes to patches. (just read the bugzilla reports linked in the announcement)

It is intresting that this guy alone could cause that glibc had to be forked. I mean this is really the core of every linux OS.

Probably the trolls on the internet are not completely wrong after all – sometimes the GPL not only allows to create free community around a project, but allows to free the project from its “community”.

ever wondered why something like this wont work when using python-clutter?

import clutter

def add_effect(obj):
    tl = clutter.Timeline(fps=60, duration=1000)
    alpha = clutter.Alpha(tl, clutter.sine_inc_func)
    bhv = clutter.BehaviourOpacity(alpha=alpha, opacity_start=0, opacity_end=255)
    bhv.apply(obj)

    return tl

def main():
    re = clutter.Rectangle()
    tl = add_effect(re)
    tl.start()
    clutter.main()

The problem is that once the function add_effect finishes, the variables tl, alpha and bhv will get garbage collected by python because they get out of scope. But they are still needed by clutter, which results in the error. To solve this you have to keep a reference to the variables somewhere, like

import clutter

tl, alpha, bhv = None, None, None

def add_effect(obj):
    global tl, alpha, bhv

    tl = clutter.Timeline(fps=60, duration=1000)
    alpha = clutter.Alpha(t1, clutter.sine_inc_func)
    bhv = clutter.BehaviourOpacity(alpha=alpha, opacity_start=0, opacity_end=255)
    bhv.apply(obj)

    return tl

def main():
    re = clutter.Rectangle()
    tl = add_effect(re)
    tl.start()
    clutter.main()

of course this way you can only have one effect at a time, so using objects for encapsulating the references would is preferable.

Do you use Ubuntu Intrepid/ Jaunty and your Brother Printer cuts off some part of the pages when printing, regardless of which paper setting you chose?

Well then this command might help you.

brprintconf_<your_model> -pt A4 # brprintconf_dcp135c in my case

the problem is, that the user interface in ubuntu only changes the CUPS settings while the brother drivers are LPR, so the settings are without effect. The command above on the other hand changes the LPR settings. If you want to know all the command options, look here.

As you probably noticed I added google banners to my page in order to get rich. They are currently only visible on article and single-news pages and should not get in your way too much.

But if they still annoy you, they are easily blockable by AdBlock or similar – if you keep them on the other hand, this will help me pay for the server.

Sidenote: Google obviously does not support XHTML with AdSense, so I had to do some tricks in order to get it to work at all – quite a shame for a so called web company…
