Time to giggle!

As Micke promised, the GIT interface would be released soon, and soon is now! Here’s the announce:

Giggle 0.1 Released!

What is it?

Giggle is a GTK+ based interface to GIT, providing developers a way to browse and visualize graphically revision trees, change logs, diffs, and other useful information.

Where can I learn more about it?

Visit The project page for more info and screenshots!

Hopefully it will be useful to many developers, there are many interesting features on the way and don’t forget that it’d be great to have your feedback :)

Managed to move my butt

Man… It’s been a lot of time since the last time I blogged, but it hasn’t been because of lack of news, here’s a quick update (in reverse chronological order):

New Job

After being a while searching for a good job, I have recently joined Imendio! They’re a bunch of nice and smart guys with interesting things to do, looks like exciting times lie ahead…

Here I go!

new g-s-t in GNOME 2.18

During the last year a lot of effort has gone into the DBus branch of the gnome-system-tools stack, lots of code have been refactored, brushed and polished to make it look better than ever (or maybe it’s me, who knows how its guts look like :). It’s really nice to see it getting at last in a stable GNOME release.

Trip to Egypt

Incredible, it was totally restless, but when you return home you’d just want to go back to see more wonders… Here’s a couple of photos to illustrate

And when you think people can’t get dumber…


Ben Maurer will be glad to read that the problem he described with system-tools-backends (which I was already aware of…) is being worked on the c-dispatcher branch. It’s still experimental and requires a bit of tweaking in g-s-t to pass messages around, but it shows a writable memory usage of ~160KB during init, that’s about 57x smaller, quite nice for a couple of evenings working on it, isn’t it? ;)

On other hacking related news, I’ve been fixing a bunch of GTK+ bugs, and it’s getting funnier by the minute, I think I’ll spend more time with it.

Random facts

When walking to the subway yesterday (some hours ago) I noticed that in front of a nursing home for the elderly there was a huge sign announcing funerary services, what do they want to get with this sign? letting them know they’ll be trying to suck their money even after their death? making them even more aware of what awaits them? whatever the answer is, I found it a quite disgusting sample of how uncaring and egoistic may be society…


Let me say you that you’re then the second last human being without mobile phone :) (I should buy one soon too, though…)


When I left my last job I promised myself to find an exciting job… didn’t get that, but instead I’m seizing time and travelling a lot. In a few hours I’m travelling to Egypt to spend there a week, it’s the 9th country I’ve visited this year, but I find this one pretty exciting! I’ll continue my job search after this travel :P


Just returned from the GNOME developers meeting celebrated in Zaragoza (Spain). It has been quite productive, with workshops about the longstanding GNOME-Hispano project “libro de programación en GNOME” [1] and Evince (courtesy of KaL) and Planner (Courtesy of acs) hacking sessions, there came new people interested in GNOME development [2] and of course we were partying overnight too!

On my side, I’ve also managed to make g-s-t, liboobs and s-t-b releases, and porting to the DBus architecture 95% of the cool patches by Darren Kenny and (I think) Erast Benson to add support for OpenSolaris and Nexenta, with this patch I think s-t-b 2.0 is very close!

On Ubuntu and g-s-t

After reading several comments on the Umbrella project, and talking with Michael Vogt and Daniel Holbach I had to drop my feelings about the whole thing:

As a developer

Pros: Perl “sucks”, it doesn’t suck per se, but not getting contributions *sucks* [1]. Python on the other hand is hype, currently there’s much more people willing to contribute coding in Python than coding in Perl, but that’s not news.

If there’s a Python replacement for the backends, I bet that there will be much more people willing to look at that code, and that can easily translate to more contributions, so if a framework to add support for other distributions is done too, that will make many people happy [2].

I strongly believe that s-t-b concept and structure is the right way, but experience forced me to think that it was in the wrong language.

Cons: Maybe most of the concepts would be reused, but there would be heaps of code that wouldn’t, the project status would be almost resetted to 0, it would go from supporting tenths of distros to supporting 1.

The big plan behind s-t-b, dbus, liboobs and g-s-t wasn’t just ditching the XML interface, it was to split things down to make contributions as painless as possible at any level (DBus also allows to do things that were nearly impossible with the XML interface, but that’s a different issue), For example the codebase in the backends has been shaved to 11KLOC (according to sloccount, much of it is common boilerplate, specific code for one distro must not reach more than 300-500 LOC). I’d like people to have a look at the code modifications before willing to replace parts of it (the new g-s-t structure also allows that quite more easily)

Replacing the frontends with python scripts is a different horse, reusing just the g-s-t glade interfaces reminds me what my beloved mentor Chema (RIP) told me once about RedHat doing the same a long time ago


I’ve failed, I once thought that s-t-b would be an excellent collaboration framework for distributions, the reality is that the only big distro using it now plans to switch, some other distros ship g-s-t as a curiosity and others don’t do that at all. The patches from distros, although very appreciated, have been very few, so s-t-b is miles away from where it could be (Maybe it’s just my lack of leadership, or that I’m a poor unemployed guy and don’t represent any big FS company, who knows)

In the case that Umbrella tries to do a multidistro framework (I bet it will success over s-t-b with time, people love Python after all), I don’t think I will collaborate regularly with code, I’ve been struggling with g-s-t for more than 4 years, and I’m not willing to start the very same thing from scratch. However, I’m fully available to give advice, after all I think I earned enough know-how on the subject.

I really hope that people won’t think I’m pissed off, Michael and Daniel are quite happy with their decision, if they are happy and take this to the end, I’m happy too. It’s just that I’m a practical guy, and I should focus on other parts of the desktop where my code would be more appreciated.

And now, off to my guitar lesson…

[1] Really, I think I could count contributors to s-t-b in the last year with the fingers of one hand. even my last post got no response at all
[2] You wouldn’t believe the ammount of people that tried to convince me to rewrite s-t-b in Python

A plea for help

After some months of apparent inactivity in gnome-system-tools, during the last couple of weeks I’ve been moving to HEAD the changes done in the experimental branches and closing heaps of bugs. Finally today I’ve been able to make releases for system-tools-backends 1.9.0, liboobs 0.1.0 and gnome-system-tools 2.15.0.

These releases mean a significant step forward, s-t-b now features a DBus interface (Thanks to Net::DBus, courtesy of Dan Berrange, thanks!), liboobs provides a GObject interface totally abstracted of the communication layer, and g-s-t takes advantage of it.

This also means that lots of code have been refactored/deleted, this specially concerns me in the backends. Given the wide range of distros it supports [1], and my impossibility to test them all [2], I’d thank if anyone could test the tools in their favorite distro. For the record, I’ve already tested them in Debian/Ubuntu and everything worked as expected :). If you want to help, I’ve setup a wiki page explaining how to compile & test g-s-t HEAD, so please if you find something that doesn’t work as expected in your distro, file a bug or send me a mail (carlosg at gnome dot org), I’ll take care of fixing it.

[1] Really, lots. But testing with latest Ubuntu/Debian, SuSE, FreeBSD, Gentoo, Fedora, … should cover 99% of the code paths

[2] Liboobs eases the creation of automated tests, but I’m also lacking enough HDD space

Pacing deserted roads to find a seed of hope


Said and done, I’m leaving my job in a couple of weeks.


Quite fun overall again, lots of friends came to see us and it seems they’ve enjoyed too (unless they lied to us! ;).

/me singing (badly), Merche to the right

Merche and I again

Too bad that there isn’t any good photo of Felix (the other guitarrist)!

BTW, Ploum, thanks a lot for the feedback and for the links! I’ll have to search more sites like these :).

Ready to break through the prison wall

Hmm, 7 months without posting, I’m beating all records…


Work-wise, sucking, I badly need a break, and I think I’ll take it soon.

Besides that, since last post I joined a music band [1], recorded a demo and played once in concert, which was actually really really fun, I loved the experience :).

In fact, we’re playing again this saturday (4th Feb), so if you live anywhere near Madrid, don’t forget to drop here!

[1] Spanish only ATM (sorry) and missing a recent/decent photo, that one is with the former guitarrist…

GNOME and hacking stuff

I haven’t been giving much love to the gnome system tools lately, unsurprisingly, I missed the schedule for including all the features I wanted for 2.14 (mainly liboobs, with improved communication, error control, etc…), but there were much progress in this and I hope to see it in 2.16.

Instead, during the last months I’ve been focusing mainly in GtkAssistant (now in CVS! sweet!) and in GtkNotebook drag and drop support (still ongoing, but progressing nicely), it’s been very entertaining and instructive.

Should do this more often

Finally moved my butt and made some system-tools-backends and gnome-system-tools releases (2 of the latter, don’t ask why), they mainly include the new services-admin UI, besides some other goodies and squashed bugs.

There have been some changes in the services backend, none of these should cause any harm, but if you use gentoo, SuSE, slackware or FreeBSD and want to help, don’t hesitate to test the new tool and tell me how it went :)

that’s all, thanks!
