pe partitia / sunt aproximativ 2.2 GB liberi. Cand
totul e calm, hdparm -t /dev/hda imi da cam 55 MB/s.
Filesystemul este Reiser.
Sistemul ingheata, chiar daca rulez ca user:
$nice -n 19 ./suicide.sh
unde suicide.sh contine ceva de genul
while [ 1 ];do
script_perl_cu_15_threaduri.pl &
sleep 5;
script_perl_cu_15_threaduri.pl &
..
done
stiu ca ceea ce fac e criminal, ar trebui sa fiu mai
rational, dar nu asta este important pt mine.
Important este SA NU MAI INGHETE, indiferent de ce
i-as face. inghetat inseamna ca sistemul este
inutilizabil, becul rosu care indica faptul ca se
scrie pe disc este aprins, hardul caraie, dupa o
perioada becul se stinge, hardul nu se mai aude
caraind, dar sistemul ramane inutilizabil, moment in
care dau restart de la buton.
