Google does not know this message, and that's the first time I see it. It was sent from an IP in Nigeria...
What do they expect with such message ? Just getting a reply ? Did any of you get this too ?
The JDLL are over, and were once again an opportunity to spend time with cool and interesting people. Due to a strike I could not go there by train on Thursday evening as planned, but we rented a car on Friday so I only missed the first day.
I only attended 2 conferences (libcaca by Jylam and DRM by Sam) and spent most of the time on GNOME booth or talking on other booths.
On Friday evening we had a Slashdot birthday party. Aurélie had organized the release of the so long awaited Duke Nukem Forever, and we now have this DVD box that I could maybe sell on eBay :)
On the way back to Paris I have also learned that driving a car is more difficult than driving Debian.
So, Ruby is OK, Perl and PHP have small memory leaks, but Python has a bunch of worrying errors including undefined behaviors and uses after free !
Of course this does not imply anything on how they manage their memory later, but I think that being clean in the simple case shows if you care about it.
Update: A Rafael wrote in the comments, Perl does not free its objects by default when the interpreter is destroyed, and even if I can't test it, running PERL_DESTRUCT_LEVEL=2 valgrind perl -e '' should not show any memory leak (if your perl was built with -DDEBUGGING). As he pointed out, perl even has a Makefile rule to run all the tests under valgrind.
Update 2: as several people pointed out, the "Use of uninitialised value" from Python are expected and harmless. Does someone have an explanation for the read after free ? :)
It is now public so I guess I have to announce it :)
I will still work for Mandriva but starting next Monday I will move to the kernel team after 3 years working for professional customers. This is a great opportunity to improve my skills in this area, I hope I will be up to the task!
After reading this last week, I had a look at the hardrive of my IBM T40 (the hardrive is only less than one year old, the previous one had died).
smartctl -A /dev/hda | sed -n 's/.*Load_Cycle_Count.* //p' told me it had experienced 540 205 load cycles within the 7037 hours it had been up. With the article talking about 600 000 lod cycles I got quite worried, and indeed I often ear clicks when I don't use the disk.
So, I changed /etc/sysconfig/harddisks to set EXTRA_PARAMS to -B 255 but that did not help : it is only run at startup and it looks like it gets changed again afterwards. I then put a cron job to set it every 10 minutes, and still got about 6000 Load Cycles in less than one day. So I changed the cron to run every minute, and I only got 11 new Load Cycle since (in 4 days !). I think they still occur at boot time, before linux has even started booting, as I could ear some while looking at options in the BIOS.
So, my solution is * * * * * hdparm -B 255 /dev/hda >/dev/null 2>&1
This is really ugly so I have to find a way to avoid the BIOS setting back this bad value.
