I have become aware of some cool stuff relating to Ubuntu over the last few days. The first thing I saw was the project called Nexenta which is putting Ubuntu on top of the OpenSolaris kernel. I have been of the opinion that this is exactly the kind of thing Solaris needs to get people to test it out.

Another thing I discovered was the launchpad stuff. Which I have seen before, but I guess I sort of resdicovered it now as the form have solidified a bit. Anyway seeing it now I was amazed and impressed with the openness of the Ubuntu development process, a big kudos to the Ubuntu team for this. As a Fedora user I wish my distro was developed in the same open manner.

SVG stuff

Came accross this Open Office SVG theme today by Pinheiro, which was made to give OO a KDE’ish look. Anyway I tried viewing the full set with librsvg/nautilus and they all rendered perfectly for me (afaict). It gave me a good feeling as it is not that many releases ago that every new icon set released uncovered a few rendering bugs. Pinheiro also mentioned that TrollTech is working on integrating SVG support into Qt, which was nice to hear. Things have come a long way over the last couple of years, when I started looking into SVG the setup was a very spec uncompliant librsvg and a crash prone sodipodi. Today the picture looks so much better, and Inkscape especially have really caused the usage of SVG to take off. I hope the Synfig team adds SVG support to their app, it would rock to have Synfig to make SVG animations.

gnomedesktop.org stuff

I have been an editor at gnomedesktop.org for the last couple of years, posting stories as time have allowed. Before that I was the editor for the gnome hosted newsite. I always felt that while gnomedesktop.org was GNOME biased in the same manner that linux journal is linux biased or Windows magazine is windows biased, we where still editorially indepdent. Learned yesterday that not everyone else in the community are willing to accept that. I haven’t discussed the issue much with Stro, who is gnomedesktop.org editor-in-chief so I don’t know how he sees it. Stro ended up pulling a story yesterday, which I have no issue with as he is the chief editor and as such it is his call, but I do not want us to end up as the GNOME version of Pravda.

Ok, so after some mail activity Benoit created a patch which displays ‘writeable memory’ in the GUI, which gives a better approximation of actual usage compared to the older numbers. Waldo Bastien pointed me to a blog entry from Lubos Lunak about a tool called exmap which displays something its calls ‘effective memory’ which Lubos thinks is a relativly decent value for describing how much memory an application actually use. I made a screenshot showing both the patched gnome system monitor and exmap displaying the memory usage of the clock applet. If those numbers are to believed the clock applet uses somewhere between 3 and 6 MB of memory, which might seem a bit on the high side. (but lets remember that the ‘clock applet’ is not just a clock, its a calendering application integrating with evolution data server giving you an overview of your monthly meetings etc.).

Anecdotaly exmap is the first app I ever used outside the Mandrake admin tools which use the perl-GTK2 bindings to write its GUI. Maybe there still is some hope for Perl :)

Not sure panel-applets are a good/easy testcase for memory measurement, so I looked at X-Chat using these new numbers too, exmap reports effective memory usage of 3.6 MB, g-s-m reports writeable memory at 8MB and resident memory of 11.6MB (resident memory number seemed to be the ‘old’ number people tended to be using when discussing memory usage).
