Finally Jeff commit SCHED_SMP work as SCHED_ULE

FreeBSD 7 release will get shaping up to be an awesome release 🙂

From Jeff blog :

"Well 5 years ago this summer I stopped by evan‘s house in seattle’s university district and told him I was going to write a scheduler that saturday. Today I committed my SCHED_SMP work as SCHED_ULE and I feel it finally reflects my original hopes and intentions. Much of that time was spent getting the kernel locked well enough that we could exploit some affinity. However I have experimented with a great number of schemes and ideas in the process. For now I’m satisfied. I will take a little break and work on other projects."

Thanks for your efforts Jeff  😉

1610 temperature violation detected

New server arrive, HP proliant ML 350 G4 P . With four SCSI HD.

ready to replace our old email server 🙂

Just a problem that arise with heatsink that prompt message " 1610 temperature violation detected "


wait more than 5 minutes for cold the machine has no impact.

A few result from google lead me to this post,

After remove "sticker like" stuff  between heatsink and cpu make everything goes normal.

simple thing but make me nuts for  few days 🙁

Moral of story : keep fight 🙂

pdf spam, reincarnation of image spam?

gmail is great, when my old email server suffering with email pdf spam. Spam folder in gmail already filled with this pdf type  🙂

Some opinion :

from securiteam :

"I have been getting lately more and more PDF based spam, the PDF itself appears to be just a cover for the normal image spam. The idea I believe is that PDF is not investigated by most spam filtering agents, and is not regarded by spam filtering as a “score giver” (i.e. what makes the email look more spamish than others)"

from heise security :

"The goal of those behind this spam is clear: the spammers purchase shares at a low price and then try to drive the price up so that they can sell at a quick profit. The companies whose stock is being promoted in this way generally do not have anything to do with such attempts at manipulation, but by the start of 2006, studies were showing that spam about company shares can actually affect share prices."

ic..ic, playing with stock for profit.



Maybe I should forward my other email to gmail for autoclean this spam 🙂
