The Amazing 3MB Operating System

Kolibri desktop is a small 3MB Operating System, which is written entirely in machine code (CPU Language) and is not based on Linux, Windows or any other variants. What is surprising is the number of applications packed into this tiny file size. There are a whole bunch of games, a basic tables editor, a compiler, a text editor, a bouquet of demos, a text based web browser and more. There is also DosBox, which lets you run almost any DOS game on Kolibri. While not meant for serious use, the tiny OS shows how bloated Windows and Linux really are.

  1. Have you heard of http://www.damnsmalllinux.org/ it is of approx 50 MB ... is that bloated ?
    it has a File browser, web browser(firefox), Word processor( which can export documents to PDF), pdf reader, email client, im client, VOIP software, web server, cd burner and much more. You still feel Linux is bloated? Its not Linux but it is the drivers, Compositing GUI, awesome effects and window managers, libraries which make it heavy(not bloated). 
    But yeah Kolibri is a nice attempt. But as it will start adding some advanced features its size would increase exponentially. 
    Last but not the least I am leaving you with 10 MB Linux http://distro.ibiblio.org/tinycorelinux/screenshots.html

  2. This would add more :)


  3. I guess you missed this update from the same source :
    Update @ 6:43 A.M. on Tuesday, September 22, 2009:
    One thing that I forgot to mention, but which is critical to the success of Linux, is that there really is no such thing as monolithic "Linux." Linux is highly modular and can be trimmed down/beefed up to fit a wide variety of applications...on the developers' terms, not Red Hat's, Novell's, Canonical's, etc.So, unlike Windows, which can only be what Microsoft dictates, Linux can truly be all things to all people, as "fat" or as "skinny" as the developer wants it to be. Ubuntu is obese compared to sub-100 KB uClinux distributions, for example. Both serve different, and useful, purposes.Read more: http://news.cnet.com/8301-13505_3-10358024-16.html#ixzz1O3XokeAE

  4. Yeah ! The same thing applies to Windows. Windows 3.1 was as tiny as it can get. With the GUI updates, features, security being implemented the size grew :)

  5. Windows 3.1 is 14.7MB, and did not had half of the features tiny core linux have today, and it is far more secure. Windows 7 in 2GB massive today. Almost all applications are same as windows XP the only thiong which made it gain size is may be a li'l bit of security and most part is beautification.
    If you observe you will find, some proprietary counterparts of opensource softwares are 100 times bulkier, without giving that much extra features in the ratio of space.

  6. Tiny core Linux are optimized and compressed to be small. Windows 3.1 was not actually optimized at that time !

    If Windows go open source, people can actually come up with Tiny Win Cores. Windows 7 is bulky bcos it consist of many many many many features. If you fail to see them, I;m sorry !

    The above difference you can see in Ubuntu and Ultimate Ubuntu ! Added packages etc and the size grew !

    Coming to open source counter parts, for eg say GIMP and Photoshop, there are so many, so many features in Photoshop that you might end your life knowing all of them. It's just you can't see it through bare eyes. Even Picasa can edit photos for you, GIMP, InfraView and Even photoshop, So why is Photoshop Heavy is a stupid question :)
