Little Big Planet has been delayed worldwide due to the inclusion of quotes from the Quran, reports VideoGaming247. In a forum thread, a Muslim user commented that he noticed two passages from the Quran in a licensed music track for the stage, “Swinging Safari.” He respectfully requested that they be removed, explaining that some consider the mixture of a holy book with pop music to be offensive. Sony pulled the game despite it already being on retail shelves in some areas, and has issued this statement:
During the review process prior to the release of Little Big Planet, it has been brought to our attention that one of the background music tracks licensed from a record label for use in the game contains two expressions that can be found in the Quran. We have taken immediate action to rectify this and we sincerely apologise for any offence that this may have caused.We’ll confirm the new launch date shortly.
Sony will probably have to press new discs that don’t include that licensed song
But the PlayStation.Blog has updated with a new release date, October 27 in North America.

While coming back to Jordan on a plane feeling happy that you missed her, you start approaching Amman
you look down through your window, you say DAMN!
what a huge graveyard! dont you ever said that or at least got the feeling??
plus its a real graveyard for youth for dreams and hope, no wonder the majority wants to leave it and live some place else.
Me and many of my fiends wanna immigrate to a better places like Newzeland for an example!!
Hopefully it works someday!!

Where to go where to work and what is the best for you?
let me talk about myself here,
I studied Computer science as my major and banking and finance as a minor.
while studying at university you keep on dreaming that you will find the perfect job
directly after you finish as you carry a computer science degree!!!
then reality hits!!!
the Jordanian market is fully occupied with people holding the same degree, and the salaries scales are very low!
you get confused and lost, is it fair to work for 180JD ?? is this what I spent 4 years for?? just 180JD!!!
that is not enough for me to go and come back from work!!
was computer science the wrong major I went into??
then I decided to change my stream after reading books for months while sitting home, and all in vain!
sales sales sales
we will pay you good, you will get extra money as you work harder, and you will meet with many people!
Thats good i guess, screw programming and all software companies who’s wanting to suck my blood!

The Large Hadron Collider (LHC) is a gigantic scientific instrument near Geneva, where it spans the border between Switzerland and France about 100 m underground. It is a particle accelerator used by physicists to study the smallest known particles – the fundamental building blocks of all things. It will revolutionise our understanding, from the minuscule world deep within atoms to the vastness of the Universe.
Two beams of subatomic particles called ‘hadrons’ – either protons or lead ions – will travel in opposite directions inside the circular accelerator, gaining energy with every lap. Physicists will use the LHC to recreate the conditions just after the Big Bang, by colliding the two beams head-on at very high energy. Teams of physicists from around the world will analyse the particles created in the collisions using special detectors in a number of experiments dedicated to the LHC.
The LHC, the world’s largest and most powerful particle accelerator, is the latest addition to CERN’s accelerator complex. It mainly consists of a 27 km ring of superconducting magnets with a number of accelerating structures to boost the energy of the particles along the way.
Inside the accelerator, two beams of particles travel at close to the speed of light with very high energies before colliding with one another. The beams travel in opposite directions in separate beam pipes – two tubes kept at ultrahigh vacuum. They are guided around the accelerator ring by a strong magnetic field, achieved using superconducting electromagnets. These are built from coils of special electric cable that operates in a superconducting state, efficiently conducting electricity without resistance or loss of energy. This requires chilling the magnets to about ‑271°C – a temperature colder than outer space! For this reason, much of the accelerator is connected to a distribution system of liquid helium, which cools the magnets, as well as to other supply services.them collide is akin to firing needles from two positions 10 km apart with such precision that they meet halfway!
Thousands of magnets of different varieties and sizes are used to direct the beams around the accelerator. These include 1232 dipole magnets of 15 m length which are used to bend the beams, and 392 quadrupole magnets, each 5–7 m long, to focus the beams. Just prior to collision, another type of magnet is used to ‘squeeze’ the particles closer together to increase the chances of collisions. The particles are so tiny that the task of making
The LHC was built to help scientists to answer key unresolved questions in particle physics. The unprecedented energy it achieves may even reveal some unexpected results that no one has ever thought of!
For the past few decades, physicists have been able to describe with increasing detail the fundamental particles that make up the Universe and the interactions between them. This understanding is encapsulated in the Standard Model of particle physics, but it contains gaps and cannot tell us the whole story. To fill in the missing knowledge requires experimental data, and the next big step to achieving this is with LHC.
The precise circumference of the LHC accelerator is 26 659 m, with a total of 9300 magnets inside. Not only is the LHC the world’s largest particle accelerator, just one-eighth of its cryogenic distribution system would qualify as the world’s largest fridge. All the magnets will be pre‑cooled to -193.2°C (80 K) using 10 080 tonnes of liquid nitrogen, before they are filled with nearly 60 tonnes of liquid helium to bring them down to -271.3°C (1.9 K).
At full power, trillions of protons will race around the LHC accelerator ring 11 245 times a second, travelling at 99.99% the speed of light. Two beams of protons will each travel at a maximum energy of 7 TeV (tera-electronvolt), corresponding to head-to-head collisions of 14 TeV. Altogether some 600 million collisions will take place every second.
To avoid colliding with gas molecules inside the accelerator, the beams of particles travel in an ultra-high vacuum – a cavity as empty as interplanetary space. The internal pressure of the LHC is 10-13 atm, ten times less than the pressure on the Moon!
The LHC is a machine of extreme hot and cold. When two beams of protons collide, they will generate temperatures more than 100 000 times hotter than the heart of the Sun, concentrated within a minuscule space. By contrast, the ‘cryogenic distribution system’, which circulates superfluid helium around the accelerator ring, keeps the LHC at a super cool temperature of -271.3°C (1.9 K) – even colder than outer space!
To sample and record the results of up to 600 million proton collisions per second, physicists and engineers have built gargantuan devices that measure particles with micron precision. The LHC’s detectors have sophisticated electronic trigger systems that precisely measure the passage time of a particle to accuracies in the region of a few billionths of a second. The trigger system also registers the location of the particles to millionths of a metre. This incredibly quick and precise response is essential for ensuring that the particle recorded in successive layers of a detector is one and the same.
The data recorded by each of the big experiments at the LHC will fill around 100 000 dual layer DVDs every year. To allow the thousands of scientists scattered around the globe to collaborate on the analysis over the next 15 years (the estimated lifetime of the LHC), tens of thousands of computers located around the world are being harnessed in a distributed computing network called the Grid.
If a black hole formed, we actually know a fair bit about what it would behave like. The first thing is, if you stuck a black hole in the middle of the Earth, the layperson’s point of view is that it would be like a vacuum cleaner that sucks the Earth in. But that’s not the right picture. If you took the sun and you replaced it with a black hole the same mass as the sun, the orbit of the Earth wouldn’t change at all. We’d still orbit it — the force of gravity doesn’t care whether it’s a black hole or the sun, all it cares about is the mass. The big problem for us is it would be dark, but the gravity wouldn’t change.
It’s not so unlikely that the LHC could produce black holes, but it’s almost certainly true that if it produces those black holes, they are going to evaporate very quickly.
Any black hole that you know about in astrophysics is much, much heavier than the ones being produced in the LHC. If the LHC produced black holes which is uncertain they might be a couple hundred times more heavy than a proton, but way less than fractions of a gram. And at that size limit, we expect them to evaporate extremely quickly through a process called Hawking radiation [which takes its name from physicist Stephen Hawking, who first proposed the theory in 1974]. It would almost certainly radiate into particles we know about like photons, and so it would look like a regular collision. The hard thing would be to actually know you had a black hole in there.
The Large Hadron Collider (LHC) can achieve an energy that no other particle accelerators have reached before, but Nature routinely produces higher energies in cosmic-ray collisions. Concerns about the safety of whatever may be created in such high-energy particle collisions have been addressed for many years. In the light of new experimental data and theoretical understanding, the LHC Safety Assessment Group (LSAG) has updated a review of the analysis made in 2003 by the LHC Safety Study Group, a group of independent scientists.
LSAG reaffirms and extends the conclusions of the 2003 report that LHC collisions present no danger and that there are no reasons for concern. Whatever the LHC will do, Nature has already done many times over during the lifetime of the Earth and other astronomical bodies. The LSAG report has been reviewed and endorsed by CERN’s Scientific Policy Committee, a group of external scientists that advises CERN’s governing body, its Council.

Lately I was reading deeply about LHC (Large Hadron Collider).
and to be honest I was impressed of what these folks have done so far.
frankly I envy them! for the level they reach in their life, a level where they want to discover new thing and prove the big bang theory!!
in a 27 km tunnel, 100m underground they want to accelerate 2 protons to the nearest level of “light speed” and then bnag bang!!!
huge computers will be monitoring the collision results and hopefully they will get what they want!
hopefully no black holes
on the other hand my colleges at work were talking about (Bab 2l7ara) and (Nour and Muhanad)
when i toled them about LHC they didn’t believe it and start laughing about it!
I really feel sorry for them for our Arabic and Islamic Nation for the emptiness our youth suffering from!
I feel sorry for the old fashioned educational systems we have in our schools and universities!
I feel sorry for each smart person who got lost and confused cause of no jobs no money cause of old stupid people who don’t know how to use a computer WHO for sorrow leads us!!
and i feel sorry for myself!!

Building websites with a lot of client script like javascript may be a nightmare sometimes!
there is a big possibility that the client disabled the javascript by mistake or does not know whats javascript is!
so am wondering when browsers like firefox IE or Opera will make javascript support as an mandatory thing, and the end-user will never ever be able to disable it?
or what could replace javascript??

After working with maktoob.com I found that more than 90% of girls working in this lovely sector
are not really girls?!?
why its hard to find a girl like the marketing and sales girl working as a developer?
why they are not friendly at all?
does the computer change something in their minds and the way they think??
I really doubt it.
mostly all of my friends who are working in the same sector do agree.
is there any reason for this??

At first I should define, what is mod_rewrite?
mod_rewrite is a part of Apache server that can rewrite requested urls on the fly.
To enable mod_rewrite in Ubuntu, you just need to write this command in terminal
sudo a2enmod rewrite17 Aug
This post will help you to install ffmpeg and compile it with some important codecs.
First, get your dependencies:
sudo apt-get build-dep ffmpeg sudo apt-get install liblame-dev libfaad2-dev libfaac-dev libxvidcore4-dev liba52-0.7.4 liba52-0.7.4-dev libx264-dev checkinstall build-essential subversion
Next, grab the ffmpeg source:
svn checkout -r 8998 svn://svn.mplayerhq.hu/ffmpeg/trunk ffmpeg
If you’re feeling adventurous, you can try the very latest code by omitting the -r 8998 part of that line. Revision 8998 is the latest at the time of writing, and worked for me.
Now you can configure and build ffmpeg. This takes a little while:
cd ffmpeg ./configure --enable-gpl --enable-pp --enable-libvorbis --enable-libogg --enable-liba52 --enable-libdts --enable-dc1394 --enable-libgsm --disable-debug --enable-libmp3lame --enable-libfaad --enable-libfaac --enable-xvid --enable-pthreads --enable-x264 make
Finally, install it.
checkinstall
gives you the option to edit some parameters: I set the name to ffmpeg and the version to 3:0.svn20070511

I just noticed lately, that most of people in Jordan who are interested in blogs and bloggers are either
gays or lesbians or someday will be.
is there any message out of that? which we cant understand?
or… What do you think??
this is my personal opinion am not fighting any one.
