Nemiver in Google Summer of Code 2011

For those of you who might not know it already, Nemiver has
been granted two Summer of Code projects.  This is exciting
news for me, and I am grateful to all the people who helped
make this happen.

In this post I'll present the hackers who presented those
two projects and give you some perspective about their
proposals.


Seemanta has been active on the mailing list of the Nemiver
project for quite some time now.  He has shown great
interest in the project and has contributed ideas and code.

When you are debugging a program and you hit "Quit" in
Nemiver while the debugged program is still running, the
debugger kindly reminds you that said debugged program is
still around and alive.  This has saved me from accidentally
quitting the debugger quite a number of time.  Seemanta is
the person to thank (warmly) for this feature.

At some point in time some people have shown interest for
having a command line interface in Nemiver, coupled with a
way to script debugging actions.  I have kind of dragged
feet in that matter because my attention is taken by
nurturing more basic features.

I was excited to see Seemanta rolling up his sleeves and
proposing to look into supporting (Python) scripting in
Nemiver.  Think about it for two seconds.  This could have
some interesting impacts in debugging interactions for
Nemiver users.  Imagine a command line interpreter for the
graphical debugger, totally written (and extensible) in a
scripting environment.  I like the fresh air that this new
horizon is bringing.

  • Fabien Parent

Fabien has been active in the Nemiver project for a while
now.  He has been instrumental in testing and providing
astute feedback for features like remote debugging and, more
recently, the integrated disassembler of the debugger.  It
took me quite some energy to add that disassembling feature
so I did really appreciate the feedback of Fabien -- and
others (hey Luca Bruno!) -- about corner cases that I left
over here and there.  Without them the damn thing would
certainly be less streamlined than it is now.

More recently he added support for GSettings to the code
base, effectively taking his share of the effort of porting
Nemiver to the GNOME 3 platform.  Not only did he do that,
but he did it in a clever and maintainable way.  The code
base basically supports GConf *and* GSettings.  Both of
which are "just" backends of the internal configuration
interface of the Nemiver project.  And there is zero #ifdef
in the client code of said configuration interface, for
those who care.  This allows me (as a maintainer) to
contemplate -- with some serenity -- the support of Nemiver
on systems that will not necessarily jump to GSettings soon.

Looking at the Bugzilla activity around Nemiver, one could
sense that the way it uses the screen estate is not
necessarily optimal today, especially when you consider the
use cases of "wide" monitors that is getting more and more
the norm rather than the exception.  In other words, there
are people out there who would like to make a better use of
their horizontal screen space, during their debugging
sessions.

I was thrilled when Fabien stood up to tackle this task of
providing Nemiver users with a better way of managing their
horizontal space during their graphical debugging sessions.

Please join me in congratulating Seemanta and Fabien!

Happy Summer Hacking!

SG45H7 power supply failure


A few weeks ago my shuttle box stopped booting. For the record, it's a one year old core2quad box with 8 gigabytes of memory and 1.5 Terabytes of hard disk. All packed in a little box that is no wider than an A4 sheet of paper.

When I hit the power button the fans would start rotating a little bit, maybe 25° and then nothing. The LEDs of the motherboards stay lit but nothing happens.

I opened the box, wiped the dust from the fans, measured the voltage and current coming out from the pins of the power supply. Both current and voltage were a bit lower than expected, but to my surprise, the box did boot again. I made sure my hourly incremental backup (rsync powered!) was doing OK, and I went back to hacking G++ as usual.

Then last Tuesday the box stopped working again. This time I removed most of the parts from the motherboard: Hard disk, DVD burner, memory sticks one by one. Each time I remove of a part, I'd try to power the box on. Still nothing.

At that point, I thought it was either the mother board or the power supply that was at fault. But how would I know? I bet it was the power supply as it was the less expensive part to replace :) So I did the "power supply paper clip test" and it appeared that the odds of the power supply unit being broken were quite high.

I figured I should probably order a more powerful power supply as the 300 Watts of the current one were probably a bit too tight for my usage.
I ordered a 500 Watts PSU (power supply unit) and got it two days later. And yes, the PSU was indeed the culprit!

Let's see how long is this new PSU going to serve.

Nemiver 0.7.1

The first bugfix release of the Nemiver 0.7.x series is out.

This version addresses various nits here and there, takes care of some low level details to make sure Nemiver works well with the Archer branch of GDB and contains some updated translations.

News file and tarball are available from the usual places.

Thanks to the continuous good work of my fellows distro packagers, the binaries should appear on a mirror near you in a couple of days.

For what it is worth, Fedora 10, 11, and Rawhide packages are available for the impatients.

Happy hacking.

Maker's schedule, Manager's Schedule

I stumbled accross this gem from the always excellent Paul Graham.
It's a nice model to grasp how programmers and managers use their time differently. I guess we all felt this intuitively, but it takes a Paul Graham to express it clearly. A must read.

Nemiver 0.6.5

So Nemiver 0.6.5 is out.

Last release was in late November 2008. Too many things to do I guess.

This release is about pushing out all the little bugfixes that happened since 0.6.4. We have been fixing little quirks here and there as they were appearing during our day to day use of the tool. The result is a tool that a bit more pleasant to use, at least for my personal workflows :)

Apart from that, the Nemiver repository moved from SVN to git and the mailing list moved to the GNOME infrastructure. You can now browse the source code from here and checkout the code by typing:

git clone git://git.gnome.org/nemiver
Fedora 9, 10 and rawhide packages should hit a mirror near you soon, but the impatients can grab them here.

Catchup

Fosdem 2009

So, Fosdem is over. Yes I am late. As always.

I caught quite a serious cold even before going to Fosdem this year, so I spent the entire event drinking tea and sleeping at 23h30 at worst. Believe it or not, I was able to wake up quite early on Saturday and Sunday, so I didn't miss any morning conference and, although I came back with the flu still, I was less destroyed than after the previous Fosdems.

"Early to bed and early rise makes a man healthy, wealthy and wise", they say. I still have to practise that one. I am not there yet :)

What is sure though, is that I had a voice extinction quite on time for my talk. yay.

So How did my Nemiver talk go ? Well, I haven't received much tomatoes so I guess either the ton of my voice was okay-ish enough to not disturb the audience during its nap, or the talk was okay-ish, or ...
Well, I guess that question shall remain unanswered for years to come.

In any case, the pdf slides of the presentation are here.

All in all, this Fosdem event was nice. Aside from the talks, I met lots of cool people and hang around with the Mandriva crew. Very nice chaps. They even took some nice photos.

Fedora

So I've finally been approved as a Fedora packager. \o/
The packages I'll be (co)maintaining so far are:
I've always be willing to take part in packaging. I was just too lazy busy to sit dow and get into the approval process. I can tick that as done now. yeeesh.

I am going to fosdem 2009

So I have booked my train ticket and hotel for this year's FOSDEM.

For those won't don't know, FOSDEM is the biggest european Free Software event, dedicated at contributors and afficionados in general who are not necessarily professionals. At FOSDEM, you don't need to wear a suit or a tie. You don't need to pay to get in. Still, you can attend high quality talks given by core contributors.

Also, FOSDEM is located in Brussels, making it a rather central place to join if you live in Europe. Plane (or train) tickets and hotels prices are relatively affordable if you book them early enough.

Clearly, FOSDEM _is_ the Free Software conference to attend if you live in Europe, are interested in the technical sides of things and would like to meet contributors for real.

I will arrive on Friday February 6th in the evening and I am going to stay at Sabina Hotel. See you all there.

One more year

So I am 32 years old today, and I still have all my teeth.

I don't like celebrating my own anniversaries because I can't forget how futile life is and how all the things that one might value can vanish at a snap of fingers. I'd rather settle down for a while to think about things that happened during the last 12 months, welcome the joyful events, accept the sad ones that I couldn't change and try to change things I can for the future.

Happy Birthday to all of you who were born a November 30.

More rhythmbox news on planet GNOME

I came across Christophe Fergeau's (a.k.a teuf) last update about his work on libgpod and its integration in my music player of choice, Rhythmbox. There are some very interesting bits in there. I wish teuf's blog could be syndicated on planet GNOME.

That made me wonder why we don't hear more often about Rhythmbox on planet GNOME. The project is very active and I use it every day. Kudos to its hackers :-) Guys, please, tell to us a bit more often about it. I am not asking for over-pimping. Just keeping in touch with your users :-).

It even looks like we are probably going to be having a nice new and native GTK+ widget coming out of it.

Thanks for that.
