Upgrading to php5

Recent announcement from php.net about end support for php4 make me thinking about upgrading to php5.

All server already use latest php4 version php 4.4.7 with mysql support (4.0.27) and apache1.37

Upgrading start from student server :

1. Uninstall all related php4 ports

2. Install php5 ports

kongja# cd /usr/ports/lang/php5 && make clean
===>  Cleaning for apache-1.3.37_4
===>  Cleaning for php5-5.2.3
kongja# cd /usr/ports/lang/php5 && make install
===>  php5-5.2.3 : Your apache does not support DSO modules.
*** Error code 1

Stop in /data3/ports/lang/php5.

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  😉

Need to order second CPU for preparing hehehehehe.

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 🙂
