While I was searching for something I stumbled upon this interesting site ..Typealyzer which still in beta analysis your blog posts and determines what kind of person you are...i give it a try and here are the results.. :D

ISTP - The Mechanics

The independent and problem-solving type. They are especially attuned to the demands of the moment are masters of responding to challenges that arise spontaneously. They generally prefer to think things out for themselves and often avoid inter-personal conflicts.
The Mechanics enjoy working together with other independent and highly skilled people and often like seek fun and action both in their work and personal life. They enjoy adventure and risk such as in driving race cars or working as policemen and firefighters.

it also gives me an analysis of what part of my brain was dominant while writing !!!! really interesting.

it is worth mentioning that it still in beta..and the results might not be very accurate at least for I am sure that I don't enjoy risks or driving race cars !! :D

Me , My Friends and a Hard Disk Drive :)

we ( me and 5 more friends )  had to prepare a presentation for our college about How Hard Disks work ,  the subject it self isn't that hard but the problem was in TeamWork , how can all of the team members cooperate  in the same project effectively without wasting time in non-useful arguments.

At the beginning we have faced a lot of problems but finally we managed to get over it by avoiding -as much as we can- to be like one of those people.

  • people who don't do any thing.
  • people who want to do every thing using their own method or style.
  • people who like to manage the team but they actually work less than they talk. :D
  • people who are used to be followers, waiting for orders to start doing something

however we managed to make something that is not bad for students in the first year.

you can Download the report from here and the presentation from here

by the way ... we also had a lot of fun :)

Me , My Friends And a Hard Disk Drive :D

Project Touchless

Touchless is a free open source application hosted by CodePlex and built using .Net technologies , it enables you to do some touch tricks by using a webcam that tracks color based markers.

According to the project main page it is divided into two parts:

-Touchless Demo is an open source application that anyone with a webcam can use to experience multi-touch, no geekiness required. There are 4 fun demos: Snake - where you control a snake with a marker, Defender - up to 4 player version of a pong-like game, Map - where you can rotate, zoom, and move a map using 2 markers, and Draw - the marker is used to guess what....  draw!

-Touchless SDK is an open source SDK that enables developers to create multi-touch based applications using a webcam for input, geekiness recommended.

they provide a nice video which demonstrate all the features off the project.


the first thing you might need after launching the demo is to set webcam and ensure that it is working then you will need to create markers, you should use a distinguished one so the camera can easily recognize and you can create more than marker , actually you will need more than one to play the demo's included.

the demo that I liked most is called the image demo were you can rotate , move and resize a photo with two markers like pictures in iphone or Microsoft surface.

and here is a screenshot where I was able to control a picture with two screwdrivers :D.


the second demo is a small snake game.

there is also another game that you can play with three other players


the last one is a paint demo where you can draw with markers.nice drawing,isn't it ? :).


Finally I hope you enjoy Multi touch with Touchless :D.

Analogy Screensaver

Screensavers were made originally to protect old CRT monitors from a problem called Phosphor burn-in which occurs when static image or text is displayed for long periods of time however they were used later on for other purposes like entertainment and security.

Modern CRT's are less vulnerable to burn-in problems and LCD screens doesn't face this problems at all so screensavers have lost their main goal that they were designed for , another thing is that screensavers consume power as when running computer normally and it causes screen aging.

According to wikipedia :

A typical LCD screen loses about 50% of its brightness during a normal product lifetime, if left on continuously

So the best thing to protect your screen is simply to turn it off when not used or configuring your computer to set the screen into a lower power mode and that could be done from power management in most modern operating systems.

However , sometimes you need a good or useful screen savers to be displayed if you are going to be idle for few minutes...

and here comes Analogy (the reason this article was written) a useful screensaver that displays a nice hybrid format clock into your screen.


Analogy is available for windows and OSX and can be downloaded from here.

WebMail Notifier - Firefox Extension -

If you are a firefox user and you don't use mail clients like outlook or evolution then you might found this firefox extension useful.

  • Simple and just do what it says.
  • Supports Many mail services like gmail , hotmail and yahoo and others..
  • Low memory usage compared to installing a complete standalone program.
  • Much more better than using mail notifiers found in Chat Clients like MSN , yahoo ....

Search Google in 2001 !!!

the Giant Company Google is Celebrating it's 10th Birthday, and in the honor of this occasion Google will give you a one month chance to search entries found in their old index (January 2001) where

"ipod" didn't refer to a music player, and "youtube" didn't refer to much of anything. !!!


the search page is found here.

Another thing is that it's not 100% like that of 2001 results as they have removed some sites also you will not find ads in search pages.

also when you search for a page you can see it's old archived version by clicking "View old version on the Internet Archive ", for more information see this FAQ page.

Compile and Execute Java Files using a bat file

I started to learn java and I needed a fast way to compile and execute small java programs that I wrote on notepad or my favorite Notepad++ and command prompt is considered a very fast way if you know that you Don't have to rewrite the command each time you want to compile or run a java file , you can just write them in a .bat file and execute all this commands with a double click.

All what you have to do is to write the commands in a text file and save it with .bat file extension.

An example of .bat file that compiles and execute a java file in my desktop :

@echo off

rem delete the old class file to avoid executing it
rem if there was an error in the new java file
cd C:\Documents and Settings\Ahmed Kotb\Desktop\
if exist a.class del a.class

rem Compile the java file(s)
cd C:\Program Files\Java\jdk1.6.0_04\bin\
javac "C:\Documents and Settings\Ahmed Kotb\Desktop\"

rem Execute
cd C:\Documents and Settings\Ahmed Kotb\Desktop\
if exist a.class java a


any comments or questions are welcomed
Hope this was useful.

Computer Uptime

Do you want to calculate your Computer Uptime ?
According to Wikipedia:
Uptime is a measure of the time a Computer system has been "up" and running.
in Windows you can follow one of the following methods :
The first one:
click start >> run and write cmd then click ok
write "Systeminfo" without quotes and you will find the system uptime

Update: there is better method suggested by Ahmed Barakat in the comments : instead of typing systeminfo and search for uptime in the results you can type ( systeminfo | find "System Up" ) to get only the system uptime thanks :)
The Second Method:
this is a great method if you dont like command line.
u can use an application to calculate uptime for u and there are alot of free great apps to do such thing one of them is Winlife 1.0.
it can be downloaded from here it is free and Small in size.
For linux users there is a command called uptime that u can use just write it in terminal and it will gives u something like this >>

Muslim Prayer Time Reminder

Do you sit a lot in front of your Computer and forget about prayers ???
here is one solution for this problem : a program that sets in your desktop and reminds u before each Prayer.

For Windows users :
Ela Salaty (towards my prayer) is a great prayer time reminder as it offers many features but unfortunately it comes with arabic interface only.

installation :
-Download a free copy from ""
-installation is easy just lunch the installer and follow the instructions


-Great and easy user interface. -Different ways to alert you to prayer time.
-Play athan with more than one voice.

-The possibility of printing times of prayer for the full month or Hijri calendar. -The ability to listen to radio stations via the Internet. -There are more features that you can find at the site or discover your self :)


the main drawback as stated before is the lack of english user interface so if u dont speak arabic there is another free program called athan basic that supports English and you can find it here

it offers the same features as “ela salaty” Plus the English user interface.

For Ubuntu Linux Users :
there is a small simple application that u can download from the official Ubuntu repositories.
-click Application >> Add/Remove
-choose all open source application from the list in the top
-search for Minbar and install it

now u can open it from application >> accessories >> Minbar

-Very simple application.
-Relatively low memory usage approximately 10.5 MB.
-Determine Qibla Direction.
-play athan.

-it lacks a lot of features found in “ela salaty” and athan basic.
-it doest come with athan sound file so you will have to search for one.
