17 Operating Systems You May Not Have Heard Of (But Should) Grab Them Now!

Unknown Operating Systems you would not have heard about.

While the Operating System (OS) is the most important system software powering the gadgets and devices we find under our fingers daily, we’re mostly familiar with the regular few: Windows, Mac OS X, Linux, and for mobile, iOS, Android OS, Windows OS, Blackberry OS, Symbian, Bada etc.

Operaitng System

But outside of these usual suspects there are many more operating systems – big, small, easy, difficult, for general or very specific uses. Here’s 8 not-so-known operating systems you might find interesting.
These operating systems, though unknown to many, are unique and amazing software. If you cannot install any of these OS you can try them with a flash drive or via a virtual environment using VirtualBox or VMWare, which you might after you find out what they have to offer.

1. KolibriOS: Smallest GUI OS

Kolibri is the smallest GUI operating system. It was forked off from MenuetOS. Written completely in assembly language, it is available in two versions: 1.44MB with essential features and 3MB with additional features. Despite being small enough to fit in a floppy disk, Kolibri is a complete and working graphical user interface.

KolibriOS

 Kolibri can be booted using a floppy disk, optical disc, flash drive or hard disk drive. It can read many file systems including FAT32, NTFS, and EXT3/4. It has applications for all basic computing tasks, such as text editor, email client, HTTP client, etc.

2. Firefox OS: Mozilla’s Mobile OS

Mozilla has tried to bring a completely open source mobile platform. . Codenamed Boot2Gecko, Mozilla branded it under the name of Firefox OS after its popular and open source web browser, Firefox. It is built on open web standards such as HTML, CSS, and JavaScript.

Mozilla's Mobile OS

It features an interface much like that of Android having home screen, notification bar, etc. It doesn’t support native apps, only web apps built using HTML5, CSS3, and JavaScript. One of the interesting features of Firefox OS is that everything inside it is a web page running on its separate browser process, like contacts manager, dialer, etc.

3. Slax: Pocket OS

Slax is a modern, live, pocket operating system based on Slackware Linux. Despite its small size of 220MB, it contains essential apps for basic computing, and you can extend its functionality using modules. Users can open a module (out of hundreds available e.g. Firefox, Libre Office) and the software will installed automatically.

Slax Pocket OS

Being a live operating system, it can run directly from the portable drive without the need of installation. You can just plug in your flash drive (with Slax on it), configure system’s BIOS to boot from the flash drive and voila, Slax boots up. It even features persistent storage, which means your data and preferences get saved in the flash drive, and are loaded automatically upon the next run.

4. AmigaOS 4.1

This month (September 2008) AmigaOS 4.1 was released. Although AmigaOS is a veteran in the field (many have fond memories of the original Amiga computer), its current version is a fully modern OS.

Amiga OS

AmigaOS only runs on specific PowerPC-based hardware platforms. The company ACube is currently marketing and distributing AmigaOS and is going to bundle the OS with their motherboards.

5. Haiku

Haiku is an open source project aimed at recreating and continuing the development of the BeOS operating system (which Palm Inc. bought and then discontinued). Haiku was initially known as OpenBeOS but changed its name in 2004.
Haiku is compatible with software written for BeOS.

6. ReactOS

ReactOS is an operating system designed to be compatible with Microsoft Windows software. The project started in 1998 and today it can run many Windows programs well. The ReactOS kernel has been written from scratch but the OS makes use of Wine to be able to run Windows applications.

7. Syllable Desktop

Syllable is a free and open source operating system that was forked in 2002 from AtheOS, an AmigaOS clone. It’s intended as a lightweight and fast OS suitable for home and small office users.

8. SkyOS

SkyOS is a closed source project written by Robert Szeleney and volunteers. It originally started as an experiment in OS design. It’s intended to be an easy-to-use desktop OS for average computer users. Well-known applications such as Firefox have been ported to run on SkyOS.

9. MorphOS

MorphOS is a lightweight, media-centric OS build to run on PowerPC processors. It is inspired by AmigaOS and also includes emulation to be able to run Amiga applications.

10. AROS Research Operating System

AROS is a lightweight open source OS designed to be compatible with AmigaOS 3.1 but also improve on it. The project was started in 1995 and can today be run on both PowerPC and IBM PC compatible hardware. It also includes an emulator that makes it possible to run old Amiga applications.

11. MenuetOS

MenuetOS, also known as MeOS, is an operating system written entirely in assembly language which makes it very small and fast. Even though it includes a graphical desktop, networking and many other features it still fits on a single 1.44 MB floppy disk (for our younger readers, that was the USB stick of the 80s and early 90s).

12. DexOS

DexOS is an open source operating system designed to work like the minimalistic ones on gaming consoles, but for PCs. Its user interface is inspired by video game consoles and the system itself is very small (supposedly this one also fits on a floppy disk, like MenuetOS) and the OS can be booted from several different devices. Its creators have tried to make it as fast as possible.

13. Visopsys

Visopsys is a one-man hobby project by programmer Andy McLaughlin. The development began in 1997 and the OS is both open source and free. Visopsys stands for VISual Operating SYStem.

14. Ubuntu for Phones: Content-focused UI

Ubuntu, the most popular desktop Linux distribution, is now available for phones under the name of Ubuntu for Phones, on top of Ubuntu for tablets, Ubuntu Server edition and Ubuntu Desktop. One of Ubuntu’s innovative features is that developers can write one app for all Ubuntu devices, which will be available via the Ubuntu Software Centre.

Ubuntu for Phone

Ubuntu for Phones focuses on content rather than controls. It is designed to make your phone content easier to access – every edge of the screen has a specific purpose, making all your apps, content, and controls instantly accessible.

15. Tizen OS: Samsung’s replacement for Bada OS

Samsung relies heavily on Android for its smartphone market share, but it’s trying to find alternative options. While it has the Bada OS, there are plans to replace the mobile OS on their smartphones with Tizen OS, an open source and standards-based software platform.

Tizen OS

Tizen offers an innovative OS, applications, and user experience via flexible and powerful development environments based on HTML5. Its smartphone technologies provide 3D window effects, multi-tasking, multi-touch, sensor and location-based service frameworks, and support for multiple screen resolutions.

16. Tails: Amnesic and Incognito OS

Tails is a Linux distribution based on Debian. Tails stands for The Amnesic Incognito Live System, and can be run (without installation) from portable mediums such as optical disks and flash drives. As it is run entirely in the computer’s RAM, all files and browsing history is automatically erased once the system is turned off (amnesic).

Tails

Aimed at preserving your privacy and anonymity while browsing, Tails implements many security tools, including the Tor anonymity network, and cryptographic tools to encrypt and secure your files, email, and instant messages to protect your private information, including your identity (incognito).

17. Qubes OS: Security-by-Isolation OS

Qubes OS is based on Xen, X Window System and Linux. Qubes provide hardened security using the security-by-isolation approach, creating many security domains, which are implemented as lightweight Virtual Machines (VMs). These domains have their own set of security restrictions, isolating one domain from the next.

Qubes OS

So if you separate your browser from your sensitive work data, a hacker or malware would not be able to access your information even if it has compromised your browser, thanks to the isolated domains and strategic compartmentalization. That’s the beauty of the security implementation of Qubes OS.
