Top 7 Free Operating Systems For Your Laptop / Netbook.
Tired of Windows, Mac OS X, and other Operating Systems paid up gradation and support? Do you feel like trying something new? Or perhaps you want to test the cutting edge in operating system design or find out what the platform of the future is going to be like.
Or you may simply want to try out a system that your friends are using to see whether you can use it for your computer.
This page lists a variety of free operating systems available that you can download and install on your computer. Many of the systems are also open source so you can also tinker with the system, find out how it works, and learn from it. Below are the excellent systems you can download right now.
1, Ubuntu
Most Linux netbook systems seem to be based off of this one in some way or another, so it’s really worth starting with Ubuntu Ubuntu is an operating system built by a worldwide team of expert developers.
It contains all the applications you need: a web browser, office suite, media apps, instant messaging and much more. Ubuntu is an open-source alternative to Windows and Office.
This operating system wasn’t exactly designed from the ground up. It’s a Gnome-based system including most of the standard Ubuntu apps (Firefox, Open Office, F-Spot, etc.) What makes this setup different is compatibility with computer hardware, and a GUI tailor-made to take advantage of the limited real estate laptop screens feature.
2, Fedora
Fedora is the second most popular Linux-based operating system as of early 2010, behind Ubuntu. Fedora is an RPM-based, general purpose operating system built on top of the Linux kernel, developed by the community-supported Fedora Project and sponsored by Red Hat.
One of Fedora’s main objectives is not only to contain software distributed under a free and open source license, but also to be on the leading edge of such technologies. Fedora developers prefer to make upstream changes instead of applying fixes specifically for Fedora—this ensures that their updates are available to all GNU/Linux distributions.
Fedora has a comparatively short life cycle: version X is maintained until one month after version X+2 is released. With 6 months between releases, the maintenance period is about 13 months for each version.
Fedora because it had fairly good support for PowerPC when he used that processor architecture. He became accustomed to the operating system and continues to use it
3, Kubuntu
Kubuntu is an official derivative of the Ubuntu operating system using the KDE graphical environment instead of GNOME. It is part of the Ubuntu project and uses the same underlying system. It is possible to run both the KDE desktop (kubuntu-desktop) as well as the Gnome desktop (ubuntu-desktop) interchangeably on the same machine.
The Kubuntu desktop is fully customizable. Originally designed to ease transition for users from other operating systems (such as Microsoft Windows) by allowing a similar desktop layout, the KDE 4 Plasma Desktop incorporates widget-centric modularity that allows the user to incorporate function similar to all other operating systems.
It is also create new functionality not found in other operating system desktops. 3-D effects are available in the standard KDE4 installation.
4, Jolicloud
Do you have a low memory low speed netbook? Then Jolicloud is the best operating system for you. It is a Linux-based operating system that is currently in development and Pre-Final testing.
This Operating system is built upon Debian and Ubuntu 9.10, but is tweaked to be more suitable for computers that have weaker specifications in terms of disk storage, memory and screen size, like netbook computers.
Jolicloud relies heavily on Chromium-based packages for running web-based applications. For Windows-only products it uses Wine.
5 Mandriva Linux
Mandriva Linux (formerly Mandrakelinux or Mandrake Linux) is a French Linux distribution distributed by Mandriva (formerly Mandrakesoft).
It uses the RPM Package Manager. The product lifetime of Mandriva Linux releases is 18 months for base updates (Linux, system software, etc.) and 12 months for desktop updates (window managers, desktop environments, web browsers, etc.).
Server products receive full updates for at least 24 months after their release.
6, Crunchbang / Cruncheee
This one’s not exactly a netbook operating system per se, but it can make a pretty good one. Crunchbang is based on Ubuntu but focuses on “speed, style and substance” to quote their website.
Based on the lightweight Openbox window manager, Crunchbang certainly is fast and could run really well on your netbook. I highly suggest trying this out if traditional netbook operating systems don’t work out for you.
It’s worth noting that in 2008, a group of EEE enthusiasts made a custom Crunchbang for EEE users: CrunchEEE. Check out Cruncheee here, but know that it’s over a year out of date.
7, EasyPeasy
Ubuntu Netbook Edition is great, but a lot of things don’t work out of the box. MP3s, for example, can’t be played until you install the codecs.
EasyPeasy aims to be simple by offering propietary applications and codecs out of the box. You’ll be pleased to find MakeUseOf favourites including Skype and Picasa included by default.
One More: Moblin/MeeGo
Moblin Linux is the light-weight Linux distribution Intel developed to run on low power netbooks with small screens and Intel Atom processors. Maemo is the light weight Linux distribution that Nokia developed to run on its handheld internet tablets including the Nokia N900 and N810.
Conclusion
There are a number of great operating systems worth trying out. I’ve only highlighted a few of the pack leaders worth checking out, but there’s a lot more beneath the surface if you’re willing to dig.

All About iPhone Serial Number.
Here is the step to describe how to locate your iPhone serial number. It is good to note down serial number to refer in future.
iPhone serial numbers come in the form WW011XXXYYZ which can be read as follows.
WW = Factory and machine ID
0 = Year manufactured (simplified to final digit, 2011 is 1)
11 = Week of production
XXX = Unique identifier
YYZ = Color, model and size
While the last 3 digits of iPhone serial number can be read as following:
VR0 (iPhone 2G Silver 4GB)
WH8 (iPhone 2G Silver 8GB)
0KH (iPhone 2G Silver 16GB)
Y7H (iPhone 3G Black 8GB)
Y7K (iPhone 3G Black 16GB)
3NP (iPhone 3GS Black 16GB)
3NR (iPhone 3GS Black 32GB)
3NQ (iPhone 3Gs White 16GB)
3NS (iPhone 3Gs White 32GB)
A4S (iPhone 4 Black 16GB)
A4T (iPhone 4 Black 32GB)
For example, the serial 79151XXX3NS is from factory 79 (presumably Foxconn), was manufactured in the 51st week of 2011, and is a white 32GB iPhone 3G.”
Note:
*This format is not applicable for CDMA iPhone 4 and iPhone 4S.
*If the first two digit iPhone serial number that stands out is 5K, which has been widely believed to be indicating a refurbished iPhone (reconditioned iPhone). You won’t get a new iPhone with serial number which starts with 5K.

How to check iPhone Fake or Not
Do you ever think that you brought a fake phone? Or did you see a cheap deal for iPhone and you suspect that it is a imitation of iPhone? You can identify a genuine iPhone from a fake iPhone. Please follow these guides to make sure you are buying a real iPhone.
Touch Screen: This is one of the easiest way to identify a fake iPhone. The real iPhone comes with a glass touch panel, where the fake one may be plastic. If you apply slight pressure on the iPhone screen and if you can see some color changes on that spot while pressing, that is fake iPhone. The second thing is the sensitivity of the touch panel. The sensitivity of a fake iPhone screen will be lower. It may take mare attempts or pressure to react with your finger movements. If your iPhone reacts with a Metal or Plastic styluses, it is not real. The real iPhone will not work with Metal or Plastic styluses.
Memory Space and Battery: The real iPhone has no memory space or card slots. It comes with one SIM card slot on top, and the batteries are not replaceable by the user, means the battery is not easy to take of from the iPhone with a sliding door. If any iPhone coming with these features, they are not real iPhones.
Touch Screen Size: If you get a chance to open and see the iPhone before you buy, please measure the screen size with a ruler. It should measure exactly 3.5 inches (8.9 centimeters) for iPhone4. If you see a lower or higher size, that is the bad apple.
iPhone Back Panel: Fake iPhones are coming with plastic back cover. The original iPhone coming with Metal panel and Glass back panel in iPhone4 models. The back of your iPhone should always list a model number, and IC ID, and the phrase “Designed by Apple in California. Assembled in China.” If you have an iPhone with any other color except black or white, it is not real one.
iPhone Icons: When you turn on iPhone, genuine iPhone will display four rows of icons with a black background. So many fake iPhones are coming with a clouded back ground.
Serial Numbers: You can get the iPhone serial number here. This post tells you all about iPhone serial number. If you see any change in the format code, be careful. Also you can check your iPhone warranty in apple website, the link also provided here. If you enter the serial number and it’s not recognized by the site, you can assume that you got a bad apple.
Menus and Apps: There should have some changes in menus in actual iPhone and fake one. You can’t see any busy hour glass or any delay while opening a new genuine iPhone. If you see these busy icon or unusual deal to open an apps, that is from a fake iPhone.
A couple of points to take care:
- When you turn on the fake iPhone, it will not give you a slide to unlock option.
- The iPhone menus may be different the icons are almost similar to original one.
- The music player and video players appearance may be differ than the original one.
- Fake one may not have auto turn off screen while calling.
- The auto rotate feature may not come with fake one.
Always try to buy from Apple store or an authorized retailer, will be a good choice to get a genuine iPhone.

Scientists plan to sail on lakes of Saturn's largest moon Titan
After the successful landing of 'Curiosity' rover on Mars, scientists now plan to navigate the seas of Saturn's largest moon, Titan.
According to scientists presenting their proposals at the European Planetary Science Congress, this outlandish scenario could soon become a reality.
The new project, called the Titan Lake In-situ Sampling Propelled Explorer, proposes a boat-probe, propelled by wheels, paddles or screws.
The probe would land in the middle of Ligeia Mare (the biggest lake, near Titan's north pole), then set sail for the coast, taking scientific measurements along the way. The mission would last around six months to a year.
"The main innovation in TALISE is the propulsion system," Igone Urdampilleta, a member of the TALISE team said.
"This allows the probe to move, under control, from the landing site in the lake, to the closest shore. The displacement capability would achieve the obtaining of liquid and solid samples from several scientific interesting locations on Titan's surface such as the landing place, along the route towards the shore and finally at the shoreline," Urdampilleta said in a statement.
The TALISE concept is being developed as a partnership between SENER, a private engineering and technology group and the Centro de Astrobiologia in Madrid, Spain.
This mission concept is the result of a 'phase 0' study. In the following phases the feasibility study and a preliminary mission architecture would be realised to consolidate a possible technical proposal for future space science mission call.
Titan is one of the most Earth-like bodies in the Solar System. With a thick atmosphere, a diameter between that of Earth and the planet Mercury, and a network of seas, lakes and rivers, it is in many respects more like a planet than a moon like Earth's.
The satellite's atmosphere is made up largely of nitrogen (like Earth's), is rich in organic compounds and hydrogen cyanide, which may have played a role in the emergence of life on Earth.
The Cassini-Huygens mission, which studied Titan extensively in the 2000s, confirmed that lakes, seas and rivers of liquid hydrocarbons (similar to household gas) exist, covering much of the satellite's northern hemisphere.
Although it eventually landed on solid ground, the Hugyens lander was designed to be able to float for a short period.
US drones will soon be overtaken by new wave of robots

WASHINGTON: The US military's current fleet of drones will soon be overtaken by a new wave of robots that will be faster, stealthier and smarter -- operating virtually without human intervention, experts say.
The Pentagon is investing heavily in "autonomy" for robotic weapons, with researchers anticipating squadrons of drones in the air, land or sea that would work in tandem with manned machines -- often with a minimum of supervision.
"Before they were blind, deaf and dumb. Now we're beginning to make them to see, hear and sense," Mark Maybury, chief scientist for the US Air Force, told AFP.
Unmanned aircraft are now overseen by "pilots" on the ground but as the drones become more sophisticated, the role of remote operators will be more hands-off.
Instead of being "in the loop," humans will be "on the loop," said Maybury, explaining that operators will be able to "dial in" when needed to give a drone direction for a specific task.
"We're moving into more and more autonomous systems. That's an evolutionary arc," said Peter Singer, an expert on robotic weapons and author of "Wired for War."
"So the role moves from being sort of the operator from afar, to more like the supervisor or manager, and a manager giving more and more of a leash, more and more independence," he said.
Despite the dramatic advances in technology, the American military insists humans will remain in control when it comes to using lethal force.
But the next generation of increasingly capable drones will stretch man's capacity to control robots in battle, generating unprecedented moral and legal quandaries.
"These (technological) responses that are driven by science, politics and battlefield necessity get you into areas where the lawyers just aren't ready for it yet," Singer told AFP.
Over the next decade, changes in computing power will enable teams of hi-tech drones to operate virtually on their own, or as "robotic wingmen" to piloted aircraft, said Werner Dahm, the Air Force's former top scientist.
At a testing range in the Arizona desert, Apache helicopters are flying together with unmanned choppers in experiments the Pentagon believes will serve as an eventual model for future warfare.
"We're not far away from having a single piloted Apache or other helicopter system and a larger number of unmanned systems that fly with that," said Dahm, a professor of mechanical and aerospace engineering at Arizona State University.
"These require very high levels of machine reasoning. We're much closer to that than most people realize," Dahm told AFP.
The new technology has turned the US Air Force's doctrine upside down. For decades, the military trained pilots to face an enemy "alone and unafraid," flying deep into hostile territory to strike at a target and then return home.
Now the Air Force is planning for scenarios in which different tasks would be divided up among manned and unmanned "systems," with drones jamming enemy air defenses, tracking targets and assessing bomb damage, while piloted warplanes oversee the launching of bombs and missiles.
