mess with uptime… wtf?
hmmm… on my virutal machine (pld builder), i got sth like this
[root@builder ~]# date
Sat May 31 22:03:00 CEST 2008
[root@builder ~]# uptime
22:03:02 up 14994 days, 16:48, 2 users, load average: 0.25, 0.42, 0.44
[root@builder ~]# cat /proc/uptime
1295542137.91 7051085.16
[root@builder ~]#
i have no idea what happened 
but looks cool
some apache performance issues
I had some problems with apache… the php was very very slow. The system has linux gentoo with hardened profile, so me and x0ff believed that this was the main reason of poor apache performance. But recompiling php without “-pic” flag does no effect.
after
# ab -c 100 -n 10000 http://localhost/test.php
Benchmarking localhost (be patient)
Completed 1000 requests
apr_socket_recv: Connection reset by peer (104)
Total of 1810 requests completed
and in apache log:
[Fri May 30 19:40:54 2008] [alert] (11)Resource temporarily unavailable: setuid: unable to change to uid: 81
[Fri May 30 19:40:54 2008] [alert] Child 16566 returned a Fatal error… Apache is exiting!
[Fri May 30 19:40:54 2008] [emerg] (22)Invalid argument: couldn’t grab the accept mutex
So… it is not - the performance problem, because only 1810 requests were done.
Because system is hardened, i have a lot of limits in /etc/security/limits.conf. I was not sure if apache uses these vaules (because they are connected with PAM!!!!), but apache did ;(
http://bugs.gentoo.org/show_bug.cgi?id=64700
so the way to make it work was adding to
/etc/init.d/apache2 a line:
ulimit -u unlimited
the whole start section looks now like this
start() {
checkconfig || return 1
ebegin “Starting apache2″
[ -f /var/log/apache2/ssl_scache ] && rm /var/log/apache2/ssl_scache
ulimit -u unlimited
${APACHE2} ${APACHE2_OPTS} -k start
eend $?
}
to be sure that everything works fine a did a ab test one more time (with pic enabled).

Without “pic” enabled i got:

so there is no big difference.
The test.php script consist of:
<?
phpinfo();

niggle: note that there is no security problem with no limit - the apache has internal limiting functions
new toys arrived :)
Today I got some toys to configure… some of this is a really cool (sometimes just expensive 
) stuff, some photos
IBM DS3400 (dual fibre channel) with twelve 750GB dualport sata drives
Back of DS3400, as we can see - two FC ports (per controller), management port, and drive expansion… at the bottom - redundant power supply
DS3400 controloller (one of dwo) with 512MB cache, work in active-active mode
HS21 blade memory… two 2GB modules and two 1GB modules… looks nice in pairs
Qlogic fibre channel expansion card for IBM blade
Feel out of memory?…
… or maybe out of power?
something about having job… [polish]
I found this text at goldenline.pl… it’s really interesting (but in polish (if sb would like to translate - do not hasitate ) )
ktos wczesniej napisal, ze w ogloszeniach kazda firma jest rozwojowa i kazda praca ekscytujaca. tez to zauwazylem i jest to wg mnie bardzo zabawne. troche juz w branzy jestem, pare firm zwiedzilem, z paroma rozmawialem i mam kupe znajomych w korporacjach typu sabre, motka czy ibm. no i zawsze jest tak, ze HRy (i nie tylko, managerowie tez maja do tego sklonnosci) to roztaczaja wizje po prostu niemal obcowania z absolutem. nowe projekty, przelomowe technologie, miedzynarodowy zespol, wyzwania, cuda niewidy… a potem czlowiek przychodzi i przez 8 godzin dziennie gapi sie w terabajtowe logi wyplute przez jakiegos tajemniczego molocha stojacego gdzies tam i robiacego nie bardzo wiadomo co. albo po raz setny sledzi sie wylot po krzywym kliknieciu. albo po raz n-ty debugujesz rysowanie kontrolki bo u klienta glupio wyglada…
tak naprawde gros pracy programisty to poprawianie bledow po innych albo po sobie samym. taka jest smutna prawda i nie ma co sciemniac ze ta firma jest super bo oni ciagle wymyslaja cos nowego. nawet jesli firma wypluwa z siebie nowe technologie z predkoscia karabinu maszynowego to zaloze sie ze max 2% obsady opracowuje te nowosci, a pozostale 98% lata dziury w teoriach.
Moim zdaniem w sektorze IT płac jeszcze przez jakiś czas nie będzie się podawać widełek płac.
Pracownicy IT szczebla średniego i niższego są z reguły postrzegani jako pracownicy od wiedzy tajemnej niemożliwej do zweryfikowania przez pracodawcę, gdyż używa on IT ale nie jest to jego źródłem przychodów.
Często na takie stanowiska aplikują lamy, które myślą, że jak się naczytały Komputer Świata to są specami z sektora IT.
Stąd na rozmowach spotykają się “zaprawieni” w bojach szeroko pojęci “informatycy” i informatyczni “gringo”.
Dla potencjalnego pracodawcy nie będącego informatykiem odróżnienie tych dwóch “gatunków” jest dosyć ciężkie, więc podejmuje decyzję w stylu “po co przepłacać…”.
Specjaliści wąskich tematów w IT są poza klasyfikacją gdyż są zatrudniani po szczegółowej weryfikacji w firmach IT.
Tu także jeszcze przez jakiś czas nie będą podawane zarobki.
Polskie firmy IT póki co są na dorobku lub są oddziałami światowych koncernów. Oddziały koncernów czasami jadą na stratach i dzięki redukcji kosztów zatrudnienia przez minimalizację płac wykazują zyski w EMEA ratując wizerunek firmy. Polskie firmy mają polską filozofię: ” po co przepłacać jak można mieć “to samo” za mniej”.
Stąd ta licytacja ujemna.
Jeszcze upłynie sporo czasu, zanim zrozumieją, że jeden dobrze opłacony, identyfikujący się z firmą pracownik, potrafi pracować za dwóch kiepsko wynagradzanych, którzy w tym samym czasie szukają nowej pracy.
hardlinks in linux - maybe a way to backup?
take a look:
marti@illusion ~/test_dir $ ls -al
total 8228
drwxr-xr-x 2 marti marti 4096 May 20 13:57 .
drwxr-x— 15 marti marti 4096 May 20 13:56 ..
-rw-r–r– 1 marti marti 8397824 May 20 13:58 pliczek
make some hardlinks:
ln pliczek plik1
ln pliczek plik2
ln pliczek plik3marti@illusion ~/test_dir $ ls -ila
total 32876
5144802 drwxr-xr-x 2 marti marti 4096 May 20 14:01 .
5029890 drwxr-x— 15 marti marti 4096 May 20 13:56 ..
5144803 -rw-r–r– 4 marti marti 8397824 May 20 13:58 pliczek
5144803 -rw-r–r– 4 marti marti 8397824 May 20 13:58 plik1

5144803 -rw-r–r– 4 marti marti 8397824 May 20 13:58 plik3
marti@illusion ~/test_dir $ du .
8220 .
it means that - links does not consume disk space, and… after rm of oryginal file:
marti@illusion ~/test_dir $ rm pliczek
marti@illusion ~/test_dir $ ls -ail
total 24660
5144802 drwxr-xr-x 2 marti marti 4096 May 20 15:20 .
5029890 drwxr-x— 15 marti marti 4096 May 20 13:56 ..
5144803 -rw-r–r– 3 marti marti 8397824 May 20 13:58 plik1
5144803 -rw-r–r– 3 marti marti 8397824 May 20 13:58 plik2
5144803 -rw-r–r– 3 marti marti 8397824 May 20 13:58 plik3
files still exist and they still have same size:
marti@illusion ~/test_dir $ du -s .
8220 .
one strange thing is as expected, “ls” reports 24660 blocks in use, seeing each of the new hard linked files as new data. But… notice what “du” reports, since it actually looks deeper into the file system
way of backup - make hardlink to every file or desired file in another place (note that hardlinks can be done only in one partition), if you wan’t to find files which has more then one hardlink just execute:
find / ! -links 1 -type f
OK - note2 (thx to xoff) - you can only be safe in way of deleting the file… not modification, and it is the chipest way of backup - that not occupy additional disk space.
install ekg step by step
Some distracted users have problem with installing EKG (console GG client for unix and linux), because of the fact that libgadu has been separated form EKG project. So… for me , and some distracted users… step by step install:
background:
- you are root in your system
- read this documentation file
- you know what you’re doing
Symptom:
after ./configure and executing make you get sth like this:

solution:
install libgadu
go into libgadu directory and do:
./configure
make && make install
there will be a very important line in make install output:
Libraries have been installed in:
/usr/local/lib
then do like this:
export CFLAGS=-I/usr/local/include/
export LDFLAGS=-L/usr/local/lib
(all depends at dir you have in output of make install)
then simply install the ekg by executing in ekg sources dir
./configure
make && make install
that’s all!
CAUTION:
- be sure that you are doing this in the same terminal - export isn’t succeeded throught sessions
- if this does not work, try to find where you have libgadu.h file (and this dir need to be set in CFLAGS), and libgadu.so (and this dir has to be set in LDFLAGS).

Hmm… today I was reviewing installed updates in my Windows Vista… and I noticed that I have both - SP1 to my Microsoft Office Enterprise 2007 and KB949031 update. The date of install sp1 was earlier that the critical security update that allow remote code execution in outlook, so… why microsoft distribute this patch even if Office 2007 SP1 is not affected by THIS critial vulnerability?
Maybe because it is Microsoft?
jak ochrona łamie wszelakie przepisy drogowe
First I would like to apologize all english language readers for article in polish, the post is directed to polish spoken users
To, że policja krakowska niejednokrotnie łamie wszelkie możliwe przepisy począwszy od zakazów parkowania, parkowanie na skwerach i jazdę po pasach przeznaczonych dla autobusów to chyba wszyscy kierowcy jeżdżący po Krakowie doskonale wiedzą.
Irytuje mnie natomiast fakt, iż wszelkiego rodzaju “justysy”, “solidni” itp. agencje ochrony notorycznie zachowują się jak pojazdy uprzywilejowane, nie dość, że łamią przepisy to jeszcze stwarzają zagrożenie dla ruchu.
Dziś natknąłem się na “Rutkowski Patrol” który to wyjeżdżając z ul. Czesława Miłosza (przedłużenie Wita Stwosza) na aleję 29 listopada skręcił niewiele przejmując się czerwonym światłem W LEWO, przecinając w międzyczasie dwie linie ciągłe.
Jak widać - stałem na czerwonym świetle na 29 listopada chcąc skręcić w lewo, podczas gdy mam czerwone światło na tym skrzyżowaniu jest tak - że samochody jadące z ul Czesława Miłosza również mają czerwone.
Rutkowski Patrol - pojazd nr 011 łamiący kilka przepisów jednocześnie (czerwone, nakaz jazdy w prawo, dwie ciągłe linie i przejazd po części wyłączonej z ruchu), przy czy nie miał włączonej żadnej syreny “policyjnej” czy nawet sygnalizacji świetlnej.
Obserwując to co się dzieje… czasem mam wrażenie że Ci co karzą często nie do końca winnych sami wykorzystują swoją pozycję do zwykłego wygodnictwa.
