PyPMU 0.1.1

I'll soon make a control-based desklets on it.
I'd like to get the C backend used by GNOME battstat applet (supports only ACPI/APM, but i steel haven't been able to contact its maintainer. I think I'll have to provide a full patch to get a chance to get PMU support in ...

LibGTop
I'm working hard on libgtop. Fixed a nasty bug on Linux/Sparc64.
I've been granted access to 5 Solaris (sparcs) machines in a German University, and started to fix Solaris support. I still haven't decided if this will go 2.8.1 or 2.9.0 ...

Today, i've wasted one hour debugging a network app : receive an UDP packet, unpack it and insert data into a PostgreSQL database. Quite simple. The program sending data is written in C.

I was getting a pg error about bad queries. So i added a try...except and a print statement on exception. Everything looked OK, i didn't understand what was wrong. So i opened a psql shell and a python shell, dumped there my query. Ran fine. I was crazy. I spent 15 minutes sending packet and watching my error log ...

Then repr came !(Python lib)
so i replace my print 'Query was %s' % (my_query,) by print 'Query was %s' % (repr(my_query),) ... there were some non-printable chars in my data (C '\0' grrrr /me stupid). repr displays them, str doesn't.

Next time, i'll be more carefull with string and i'll use repr each time i'll need to print data in an error messages.

very nice :D

last night, i've installed a debian mirror for x86 on a small server (400MHz / 128 MB)

deb http://paulla.paulla.asso.fr/debian/

i'm pretty happy with it, 'cause it's going pretty fast : 100MB/s for everyone at university !

afaik, it's working :D

i recieved a mail from mandrake cooker maintainer explaining that they don't want the rpm to use the distutils in post intallation ... ok ...

python setup.py --help-commands | grep RPM
bdist_rpm create an RPM distribution

Oh My God !

python setup.py bdist_rpm
# ...
ls dist/
pyxdg-0.5-1.noarch.rpm pyxdg-0.5-1.src.rpm pyxdg-0.5.tar.gz

so pyxdg will get soon into mandrake cooker :D

Knoppix-based distro for scientific stududents
I'm working since last summer on a KNOPPIX based distro designed for scientific students. My friend and i have worked a lot to get rid of KDE (excessive memory consumption) in favor of XFCE4 which is also Qter :D We're having troubles with non-free software (e.g. scilab) but it's getting finalized. We have a big CD usage issue so we only have French locale : btw we are just targetting our own university and may be some other french universities.

xmlrpclib.Server("http://www.advogato.org/XMLRPC")
Some of you may have noticed that i have fucked up the blog diary because of an unbalanced quote and bold tag. The result was that the entire page was in bold and that the Edit page was broken (couldn't edit/preview anymore) ... i guess the tag parser failed -- if there is one. Amen, xmlrpclib saved us ! i've just opened a python shell : login, retrieve my last entry, edit, send and that's all :D

I'm just back from the hairdresser... A cutie was washing my hair while i start thinking of Python2.3 itertools. I think i can map theses functions to C# IEnumerable. It would a good job to get some C# practice. I'll also have to learn NUnit and the C# embedded documentation system. I would give a good overview of C# and may be fun.

3, 2, 1 ... go-mono !
