As I was playing around different technologies based on IP and going though implementing a PBX at home, I reached to a new term called IMS ( IP Multimedia Subsystem).
Telecoms world got IMS fever. Major companies started implementing IMS in their infrastructures getting ready for better and newer competition.
Why there is IMS while there was something called Soft switch and different VoIP implementations ? and what is the benefit of having IMS?. That’s what I’m going to talk about in the next coming posts.

I think this figure will illustrate what is IMS

It’s nice to have a free software supporting your to use visualization on Windows.
Microsoft as usual does everything related to them but are careless for any different OSs.

Installing Ubuntu on Microsoft Virtual PC is easy but tricky…
First blog talking about it
Second Blog explaining how to

Basically , you will need to hit F4 and choose Safe Graphics mode then hit F6 and add to the end of the line and before “–” noapic nolapic vga=791

and finish the installation,
later after you reboot for the first time… you will need to hit “ESC” and press e on the first option in grub
and in the second line and press e again…
now it gives you a line for instructions, just add the same vga=791 to the end of the line , and then hit enter
finally press b to boot…
That’s all.

Today I logged in to my account in Saudi Fransi Bank, and I got this page which a bit kind of funny, How dare a bank will let their internal SQL statements to become visible to anybody logged to his account!!

Good morning Security Managers

Why do we see many of our companies do not perform correctly? I was looking for an accurate answer for this for long time, but couldn’t find a solid answer until I met a security manager in one of the saudi companies, he was claiming that even if the browser is showing you the certificate was signed verisign.com you cann’t make sure it’s true.
I thought may be he is talking about something more deep like if a virus or worm changed the public key of verisign CA which is shipped and installed in every browser.
I was shocked when he said “We are not talking about digital signature, the certificate could be faked and there is no way to make sure it’s for that company!!”

Another manager I met in the past too, when I told him one of their critical systems was unprotected by strong password and that username could be used to wipe the data on a production system, he replied simply ” we can restore the system from our backup!!!” , he couldn’t understand I was giving an example for the sake of how dangerous to have weak password.

I understand that we might have bad employees with low qualifications, but having bad managers do not understand their basic ABC responsibilities!!

I am confidence that because such unqualified in ABC basic stuff about the job, we’re getting unexpected and the worst performance ever in every job.

As we are a country that depends on Oil as our major income and as much as the price per barrel is getting higher, I get worried and I start thinking of ” What if the oil become very expensive to the level where the alternatives fuels become more reasonable comparing to Oil prices? “.

We were suffering from server slowness during the last 2 weeks. I couldn’t find the time to see why it’s slow.
Last night, I gave it a try and I figured out that our server was suffering from High CPU utilization due to a lot of php executions.
The server is hosting my website ibraq.com and some different websites related to my friends. I decided directly to install one of php accelerator to give it some speed, and xcache was there to help.
Installing xcache on FreeBSD was just like running a command it worked

Well, it’s fixed until we build extra load and then we will find another solution for it.

Today, I installed Safari for the first time. I was a person who really does not care about newly browsers coming to the market. But while I’m using iTune which I like it, it came to my mind “why not to give Safari a look…” and surprisingly it looks perfect than I never expect.

Smooth browsing, clever screen space utilization, clear font type, and much more.

I’m not marketing guy. However, I believe in sharing knowledge and experience, so believe me this is really worth to try.

قد يقول قائل أن الرياض تعاني من كمية خرافية من السيارات،
و في الحقيقة ان كمية السيارات في الرياض مقارنة باتساع الرقعة تعتبر لا شي
