Mohammed Almadhoun: Gets an Award from Google
My 14 year old brother Mohammed Almadhoun, won a programming contest at Google’s event in Gaza, Palestine and was awarded an Android Nexus S phone.
This is what a representative from Google had to say about him:
“To continue on this, there is actually one more person that I would like to put a little bit of spot light on; I’ve been really impressed by him, and I’d like to ask him to come to the front; Mohammed Almadhoun. I’ll give a little bit of a background story about Mohammed [Salam Alykom]. This is my hero and my role model. To give a little bit of a background; Mohammed is a 14 year old developer and I’m really impressed by the things he showed me today, but also the things that he’s doing beyond the event today. He’s done for us today the Android challenge that we had over lunch. He managed to completely solve the problem except for a little detail which is irregular expression which a lot of people at Google still don’t know how it works, and his solution was completely correct. Not only that, we had a very nice conversation in which I was really impressed by his applications are not great only but also very relevant to the local community. Give the example of Tasawaq [Is anybody familiar with Tasawaq?] This is the hero behind Tasawaq. Tasawaq is an online project which allow merchants to sell their products to all of you , and I heard of many more examples of you [...] I’m really really very impressed and I would like to give this to you as a little support for your great efforts and your energy. And I look forward to using your Android apps next year hopefully. Yes, so Thank you!”

JavaScript: Convert String to Integer (int)
To convert strings (text) to integer (number) in JavaScript use the parseInt function.
For example:
document.write(parseInt("23 years"));
Will return the number 23, the function ignores the string “years” and return the integer 23 only.
Another common example is:
<script> var firstNumber = prompt("Enter the first number"); var secondNumber = prompt("Enter the second number"); var theTotal = firstNumber+secondNumber; document.write(firstNumber + " added to " + secondNumber + " equals " + theTotal); </script>
If you enter 4 and 5, the script will return “45″ instead of 9. To fix use the parseInt function as follows:
<script> var firstNumber = parseInt(prompt("Enter the first number")); var secondNumber = parseInt(prompt("Enter the second number")); var theTotal = firstNumber+secondNumber; document.write(firstNumber + " added to " + secondNumber + " equals " + theTotal); </script>
PHP: Check If Two Strings Are Similar
Here’s a PHP function that’ll help you check if two strings (texts) are similar. If the strings are 50% similar then the function will output “Duplicate Entries”.
<?php function issimilar ($otext,$ctext){ $array1 = explode(' ',$otext); $array2 = explode(' ',$ctext); $result = array_intersect($array1, $array2); if (count($array1) > 0) { if (count($result)>(count($array1)/2)){ echo "Duplicate Entries"; }; }; } issimilar ( "Hello World Foo Bar Baz", "Hello Foo Bar Baz"); ?>
