Kolibri OS – smallest OS with GUI

KolibriOS is as small as 1.4 mb and can fit in your Grandfather’s floppy disk. Kolibri OS is a free operating system based on Menuet OS and is available in two different versions, 1.44 MB and a big one – with more features – of about 3 MB. It is written in assembly language and you can boot into it using any of the following. floppy disk, hard disk, CD or DVD.

It does not have any good graphics or does not even support the variety of softwares which are available for Windows, Linux or Mac. But believe it or not, it has everything that is needed for basic tasks e.g Text Editor, Email Client, Task Manager, Programming Tools and a virtual desktop too.It also consists of a simple http client to surf the internet.

This OS supports NTFS file system and requires only 8 mb of RAM to run. Don’t underestimate this OS because of its size. It has almost 8-10 games like tetris, rocket fight(don’t remember the exact name)  etc. This OS can be actually very useful when you have to access some data from age old machines.

You can boot into this OS using Floppy, CD/DVD or your Hard Disk. Or you can also boot into this OS using any virtual machines like VMware or Sun VirtualBox

This is the smallest OS with GUI I have ever seen. If you know any other OS which is as small as this one and also has a GUI then please let me know.

s i x t h s e n s e - a wearable gestural interface (MIT Media Lab)

The SixthSense prototype implements several applications that demonstrate the usefulness, viability and flexibility of the system. The map application lets the user navigate a map displayed on a nearby surface using hand gestures, similar to gestures supported by Multi-Touch based systems, letting the user zoom in, zoom out or pan using intuitive hand movements. The drawing application lets the user draw on any surface by tracking the fingertip movements of the user’s index finger. SixthSense also recognizes user’s freehand gestures (postures). For example, the SixthSense system implements a gestural camera that takes photos of the scene the user is looking at by detecting the ‘framing’ gesture. The user can stop by any surface or wall and flick through the photos he/she has taken. SixthSense also lets the user draw icons or symbols in the air using the movement of the index finger and recognizes those symbols as interaction instructions. For example, drawing a magnifying glass symbol takes the user to the map application or drawing an ‘@’ symbol lets the user check his mail. The SixthSense system also augments physical objects the user is interacting with by projecting more information about these objects projected on them. For example, a newspaper can show live video news or dynamic information can be provided on a regular piece of paper. The gesture of drawing a circle on the user’s wrist projects an analog watch.

What is Dual Core Architecture :

Once upon a time when human realized that in a normal atmosphere its not possible to increase the CPU Clock speed above standard levels because of too much heat generated by CPU, Both Intel & AMD have hit the Clock speed boundary line. Heat is enemy of any processor and high clock speed means high heat and that means errors or “BOOM”. Desperate need of more speed ( faster processing) is the basic reason of why technology turned or shifted to Dual Core. So rather then increasing the clock speed of Processor it was decided to put two CPUs in One. That is what we call Two Cores or Dual Core. Nowadays Quad Cores (4 cores) and even Dual Quad Cores (8 Cores) are there in market.

In a layman’s tongue here's an example. Let's say a single core (Pentium 4) is a two lane road with traffic running at 100kmph, and a Dual Core is a four lane road with a traffic running at 100kmph, and a Quad core is eight lanes running at 100kmph. All lanes (cores) are running at the same speed, but more lanes (cores) can pass a lot more traffic (Information or Data) than a single.
