Iran launches homegrown satellite
Iran says it has launched its first domestically made satellite into orbit.
President Mahmoud Ahmadinejad said the launch had been successful and that with it Iran had “officially achieved a presence in space”.
The satellite, carried on a Safir-2 rocket, was meant for telecommunication and research purposes, state TV said.
France has expressed concern, saying the technology used was “very similar” to that used in ballistic missiles. Iran insists its intent is peaceful.
Iran is subject to United Nations sanctions as some Western powers think it is trying to build a nuclear bomb.
Tehran denies that claim and says its nuclear ambitions are limited to the production of energy.
Officials from six world powers – the US, Russia, China, UK, France and Germany – are due to meet in Germany on Wednesday to discuss the nuclear stand-off.

The launch of the Omid (Hope) satellite had been expected and was clearly timed to coincide with the 30th anniversary of the Iranian revolution, says the BBC’s Jon Leyne in Tehran.
Mr Ahmadinejad said the satellite was launched to spread “monotheism, peace and justice” in the world.
But the launch could cause alarm in the West because of fears the technology could be used to make a long-range missile, possibly with a nuclear warhead, our correspondent says.

IRAN SPACE AMBITIONS
Feb 2009: Iran declares launch of first home-built satellite into orbit
Aug 2008: Iran launches rocket ‘capable of carrying satellite’
Feb 2008: Iran launches research rocket as part of satellite launch preparations, Tehran says
Feb 2007: Iran says it launches rocket capable of reaching space, which makes parachute-assisted descent to Earth
Oct 2005: Russian rocket launches Iran’s first satellite, Sina-1

Iran will no doubt reply that it is once again being judged by double standards for using a technology that is commonplace in many other parts of the world, he adds.
Speaking after the launch, Iranian Foreign Minister Manouchehr Mottaki stressed the project was peaceful.
“Iran’s satellite technology is for purely peaceful purposes and to meet the needs of the country,” Reuters agency quoted Mr Mottaki as saying, on the fringes of an African Union summit in Ethiopia.
But French foreign ministry spokesman Eric Chevallier said France was “very concerned” about the launch.
“We can’t help but link this to the very serious concerns about the development of military nuclear capability,” he said.
UK Foreign Office minister Bill Rammell said the test underlined the UK’s “serious concerns about Iran’s intentions”.
“There are dual applications for satellite launching technology in Iran’s ballistic missile programme,” he said in a statement.
“As a result, we think this sends the wrong signal to the international community, which has already passed five successive UN Security Council resolutions on Iran’s nuclear and ballistic missile programme.”
Last August, Iran said it had successfully launched a rocket capable of carrying its first domestically built satellite, having in February launched a low-orbit research rocket as part of preparations for the satellite launch.
That launch marked the inauguration of a new space centre, at an unidentified desert location, which included an underground control station and satellite launch pad.
The White House called the 2008 launch “unfortunate”, warning it would further isolate Iran from the global community.
In February 2007, Iran said it had launched a rocket capable of reaching space – before it made a parachute-assisted descent to Earth.
In October 2005, a Russian rocket launched Iran’s first satellite, the Sina-1, which carried photographic and telecommunications equipment.

I have already discussed what is LAMP , so please refer to my earlier post . For all lazy people ,I am giving the link to the post . http://kar2905.wordpress.com/2009/01/23/lamp/ In this post , I would be describing the process of installing LAMP on Ubuntu . I currently have Ubuntu 8.1 , apache 2.2 , php 5 I am explaining the process in a very simple manner starting from the bascis . As being new to this , I know how difficult it is to do anything on Linux . It took me a lot of time to understand fully LAMP and then install it ( thanx to the poor speeds by ION) . Note : Sentences between quotes are the commands you need to type as it is . First of all we will be installing apache 1. Open Terminal . ( Apllications -> Accesories -> Terminal ) type “sudo get-apt install apache2“ 2. The terminal will ask for your password , just enter it . ( if it doesnt ask , dont panic there is nothing wrong in it) Now To test apache 1. open a web browser . Go to a new tab . Type “http://localhost” , press enter . If everything is all right , it should display “IT WORKS!! “ Hurray , you have successfully installed apache Now , we have to install php 1. open a terminal ( same procedure as told above ) . 2. type “sudo apt-get install php5 libapache2-mod-php5= “ It will take a little time to download ( the time depends upon your net connection) 3. Now , restart apache , as apache doeesnt know that you have installed php and hence we are restarting it so that it can integrate php into it . To restart type “sudo /etc/init.d/apache2 restart” into the terminal . TESTING PHP 1. In the terminal , type “sudo gedit /var/www/testphp.php“ This will open a file named testphp.php 2. type this into the file “” . phpinfo() is a inbuilt php function which finds out the details about apache and phph.test1 3. Save the file . 4. Now , opena browser , type “http://localhost/testphp.php“ 5. Something like this should open . I am pasting a screenshot of it . If this comes , then it means your php and apache are working fine . Hurray !! TIP : If your net connection ( as is the case with me ) , you can always open two terminals thereby working on both of them and saving time . Now to install MY SQL 1. Open the terminal . Type “sudo apt-get install mysql-server” . 2. We are now going to install a program called phpmyAdmin which is an easy tool to edit your databases. Copy/paste the following line into Terminal: “sudo apt-get install libapache2-mod-auth-mysql php5-mysql phpmyadmin“ After that is installed our next task is to get PHP to work with MySQL. To do this we will need to open a file entitled php.ini. To open it type the following: “gksudo gedit /etc/php5/apache2/php.ini“ Now we are going to have to uncomment the following line by taking out the semicolon (;). Change this line: “;extension=mysql.so“ To look like this: “extension=mysql.so“ Now just restart Apache and you are all set! “sudo /etc/init.d/apache2 restart” . Do one more thing , Type this in the terminal “sudo ln -s /usr/share/phpmyadmin/ /var/www/phpmyadmin“ . This actually copies the files to the document root directory i.e www . # /usr/share/phpmyadmin/ is the directory where phpmyadmin installed # /var/www/ is your document root directory Voila , you are all set with LAMP . Thanks every1 for reading this . It took me a lot of time to write this . As always , Comments are welcome .

Coimbatore, Jan 31 (PTI) As ISRO scientists are decoding the data sent by Chandrayaan-1 from the Moon, the space agency is confident that India’s first lunar mission would reveal “unexpected results and things”.
“The data have been collected from unexplored area. We are well positioned with these data. We can tell the world that we have found many things, which no explorer has seen so far,” Chandrayaan-I Project Director M Annadurai said today, while interacting with students of Avanashilingam University for Women here.
Replying to a question by a student whether India can achieve any unexpected results from the mission, he said scientists were working on it (data). “It may take some more time to review, re-evaluate and publish,” he said.
Stating that the research carried out on the stone brought from the moon some 30 years ago had revealed the existence of water there only at the fag end of 2008, he said India’s data would definitely show the world something which nobody had seen so far.
To another question, he said there were absolutely no plans to bring oil or water, even if existed on the moon.
“We are not trying to bring oil, water or any other mineral except Helium-3, for utilising in the Earth. We are exploring whether humans can sustain in the conditions prevailing on the Moon,” he said. PTI

WASHINGTON: Scientists have found a way of accelerating bone growth through nanotubes
and stem cells, potentially leading to quicker and better
recovery from orthopaedic surgery. Stem cells have been in the news for the revolutionary medical benefits they confer because they can be converted into selected types of newly generated cells. University of California at San Diego (UCSD) researchers used a nano-biotechnology method of placing mesenchymal stem cells on top of ultra-thin titanium oxide nanotubes in order to control conversion paths, called differentiation, into osteoblasts or bone building cells. Mesenchymal stem cells, which are different from embryonic stem cells, can be extracted and directly supplied from a patient’s own bone marrow. “If you break your knee or leg from skiing, for example, an orthopaedic surgeon “But what we anticipate through our research is that if the surgeon uses titanium oxide nanotubes with stem cells, the bone healing could be accelerated and a patient may be able to walk in one month instead of being on crunches for three months. “Our in-vitro (lab) and in-vivo (body) data indicate that such advantages can occur by using the titanium oxide nanotube treated implants, which can reduce the loosening of bones, one of the major orthopaedic problems that necessitate re-surgery operations for hip and other implants for patients,” Jin added. “Such a major re-surgery, especially for older people, is a health risk and significant inconvenience, and is also undesirable from the cost point of view.” This is the first study of its kind using stem cells attached to titanium oxide nanotube implants, said a UCSD release. The study has appeared in the Proceedings of the National Academy of Sciences. will implant a titanium rod, and you will be on crutches for about three months,” said Sungho Jin, co-author of the study and materials science professor at the Jacobs School of Engineering. var zz=0;var sldsh=0; var RN = new String (Math.random()); |

Now get a laptop for Rs 500 only
New Delhi, Jan 31, 2009: When three days from now Indian Minister for Human Resources Development Arjun Singh launches National Mission on Education through Information and Communication in the holy city of Tirupati it will write a new chapter in India’s quest for entering technology age.
National Mission on Education through Information and Communication is probably India’s ruling alliance United Progressive Alliance’s most ambitious plan in its five year tenure. Its decision to make available Rs 500 laptop to students and educational institutions is simply unbelievable.
The government has decided to produce rupees five hundred laptop on mass scale that has been developed by several top technical institutions in the country including Indian Institute of Technology Chennai as Vellore Institute of Technology besides a few other institutions.
Though there are not many details about the new laptop under this project but sketchy details say that the laptops will have 2GB memory, WiFi Ethernet. More details are set to be revealed to the world when Arjun Singh unveils the prototype of the promised laptop.
National Mission on Education through Information and Communication as the government has said will work in close cooperation and collaboration with other Missions/Schemes such as the National Translation Mission, Vocational Education Mission, National Knowledge Network, Scheme of ICT to avoid any duplication and attain synergy. It would operate through inter-departmental and multi-disciplinary approach. On the one hand, the Mission would create high quality e-content for the target groups and on the other, it would simultaneously extend computer infrastructure and connectivity to over 18000 colleges in the country including each of the departments of 419 universities/deemed universities and institutions of national importance on a single point rental basis through the Department of Telecommunications (DOT), in a manner that would permit their seamless interaction with a integrated National Knowledge Network. The advent of very low-cost-low-power consuming access cum computing devices, would further enhance the reach of the network.
Tata Motor’s Nano car may not have hit the market even several months after its intended launch, but this nano computer should be a reality within a very short time.
