TransOS – OS in the Cloud

Have you ever thought you can use your PC without actually having a Hard Drive attached to it???? Yes, it is absolutely possible.

Due to the advancements in Cloud Computing many of the organizations are shifting to VDI (Virtual Desktop Environment) which has many advantages which will be addressed later in this article.

TransOS – A new-cloud based operating system for all kinds of computer is being developed by researchers in China.

Most of us must have used a Microsoft product atleast once in a Lifetime….Many famous Microsoft products like WINDOWS OS, Microsoft office etc., According to the recent statistics more than 70% of people who use Computers have Windows Operating System in it and the remaining use other OS like LINUX and MAC….

This is the reason why Windows is much affected by Virus than any other OS, as the number of users are more all the hackers will try to target the larger population so we have around 100,000 known computer viruses only for Windows.

More of the complaints we get regarding Windows PC is about virus infection. You cannot use a Windows machine without antivirus or anti-malware. Even after having these programs installed there is still the risk of getting infected. Sometimes, viruses and malware even get past the best solutions. On the other hand, with Linux, you don’t need to worry at all about this. Your PC will hardly get infected with viruses with this operating system.

One of the key reasons LINUX and Mac are less prone to virus infection is that these systems require privileged access to install and run viruses. Malware rarely is able to gain root or privileged access to these devices and so it is more difficult to leverage system vulnerabilities. The idea that the dominance of Windows is a reason for its susceptibility is specious. LINUX install base covers everything from embedded processors to super computers. While Windows is definitely the dominant desktop OS, the increasing prevalence of embedded devices is rapidly making LINUX the most prevalent OS in the world. All without a major increase in susceptibility to malware.

Advantages of Linux

Stability 

If you have used other operating systems, once you have made the switch to Linux, you will notice that Linux has an edge over Windows here. I can remember rebooting Windows many times over the years, because an application crashed, and I couldn’t continue working. Linux can crash also, but it is much harder to do. If an application crashes in Linux, it will usually not harm the kernel or other processes.

 Free Software

Most software can be obtained without cost for Linux. For example, one thing that has kept people from Linux is the lack of office software. That has changed with Open Office, and now you can edit documents and presentations from the popular Microsoft software. The conversion isn’t 100% perfect, but it has worked remarkably well in allowing me to correspond and use documents that people send me via e-mail or the web.

 Runs on old hardware

If you have an old 386 or 486 laying around collecting dust, you can use this to run Linux. I remember running Linux just fine on a Pentium 100 with a 1 GB disk drive, and 16 MB of memory. One use of an old machine like that could be a file server. Just go to your computer store, buy a large hard disk (as long as your old stuff can support it), and you can make a great storage server. With all the digital pictures and movies around today, this could be a great use for Linux. Look into using Samba, a server application for Linux that allows you to make your machine share the disk as a Windows share.

Security

Linux has the advantage of the code being in the public domain. This can be a double-edged sword; while you can look at the code, and developers can fix holes rapidly, it also means hackers can find bad code. I have been very impressed with the security of Linux, and the programs that run on it. I think having the code out in the open, and the ability to fix things yourself if necessary is a big plus. Who likes to work blind? With some distributions, on installation the computer will ask you what levels of security you would like for your system. You can be very trusting, or you can be paranoid. Linux gives you this flexiblity.

As the complete world now wants to use Android, and IOS to some extent…..NOKIA is keen to use LINUX as its open OS to be installed in the upcoming Smart phones….Lets see whether it could give a tough fight to its competitors APPLE and GOOGLE.

The world’s biggest mobile phone maker, Nokia, could start to use open-source Linux software on its more expensive phone models, a senior company official said on Tuesday. Nokia recently unveiled a smart phone N97 recently.

In the longer perspective, Linux will become a serious alternative for our high-end phones,” Ukko Lappalainen, vice president at Nokia’s markets unit, told in an interview on the sidelines of the “Nokia World” industry conference.

Linux’s role in the handset industry is growing as Google has introduced its Linux-based Android platform, but Lappalainen said Nokia was likely to stick to its own Linux development.

Nokia uses Linux maemo software in its niche offering of Internet tablets, while it uses Symbian software for its phones.

The Nokia N900 runs on the Linux-based Maeme 5 software, featuring true multitasking with applications as well as Web browsing with Adobe Flash support.

Nokia’s workhorse Symbian operating system controls half of the smartphone market volume — more than its rivals Apple, Research in Motion and Google put together. Nokia said Linux would work well in parallel with Symbian in its high-end product range.

Windows 8 Tablet PC

Like Apple’s latest attempt at a desktop OS, Windows 8 borrows largely from its mobile kin, Window Phone 7, bringing its signature live tiles to tablets and PCs, and from what we’ve seen it does so effortlessly. Before we go ruining a good thing, however, we have to point out that this isn’t everything Windows has to offer — it’s still a developers preview (and in turn, an OS under construction), and the device it’s running on hasn’t been approved as an official Windows 8 slate. Got all that? Good. Read on for our first impressions!

Metro style UI

 

You’ll hear the words “Metro-style” almost endlessly surrounding the release of Windows 8. Live tiles, hidden menus and controls, large, flashy graphics, bold white type, multi-touch gestures: these are the characteristics that set the OS apart from its predecessor and, to some degree, from its competitors. You won’t see any of the old, static Windows here, unless of course you choose to — the desktop that you’ve grown used to in Windows 7 is still present, albeit as an app, but more on that later. If you’re familiar with Windows Phone 7, the user experience should be pretty familiar, but not entirely so.

 

Touch Gestures

One thing becomes abundantly clear when you’re zipping through those customizable live tiles: Microsoft is banking on touch screens. The outfit’s execs weren’t shy on that point at yesterday’s press preview, going so far as to say that “a monitor without touch feels dead,” but the proof is in the pudding. Fortunately, most of the touch gestures are perfectly responsive; simple swipes left and right allowed for quick scrolling, a swipe from the right edge of the screen pulled up the appropriate navigation menu, and a gentle tap and pull on any given tile selected it for customization, but there was one gesture we never managed to master. Live tiles are supposed to be easily reorganized, and they are, but so are their selected groupings. A simple pinch-to-zoom technique should bring up a simplified overview of the entire start page, allowing you to rename and customize groupings. However, no amount of pinching or prodding could get our prototype to fall in line, thus our tile teams went unnamed.

Keyboards

Because not every PC has a touch screen quite yet, we’ve been told you can use the conventional keyboard and mouse to make your way through the new UI. While we weren’t able to get our hands on a compatible mouse in time for this write up, we did give the Series 7’s keyboard a spin, and, much as we experienced in our first hands-on with the device, it got the job done. But Windows 8 is clearly a touchy-feely OS, and its various ways of getting text on the page are a testament to that. There are three different methods for text input: two touch keyboards and handwriting. We were amazed that throwing down our signature chicken scratch actually proved fruitful, but handwriting on any computer still seems counterintuitive. The other two keyboards were responsive, and the layout was as good as any we’d seen.

 

Metro Style Internet Explorer 10

That full-screen experience is carried over into the browser, which also gets the Metro treatment, giving you unencumbered viewing of whatever it is you look at on the internet. Frankly, we’ve never been put out by scroll bars, tabs, or URLs, but it seems nothing is untouched by Windows 8’s new Metro wand. And, truth be told, after doing without for a while, we’re not entirely sure we miss all the added distractions.

Differences between iOS & Android

Now is the Revolution of Touch Phones ( Smart Phones) and Tablet PC’s, many of us are little confused as to choose between a Iphone and an Android Phone….I Think this article would completely relieve you from the confusion….

Apple has its brand name already existed in the market  whereas Android is completely new, introduced by google in the year 2005.

Android versions are difference in tastes which are Cupcake (Android 1.5, Based on Linux Kernel 2.6.27), Donut (Android 1.6, Based on Linux Kernel 2.6.29), Éclair (Android Version 2 and 2.1, Based on Linux Kernel 2.6.29), Froyo (Android Version 2.2 , Based on Linux Kernel 2.6.32) , Gingerbread ( Android Version 2.3, Based on Linux Kernel 2.6.35.7) and Honeycomb (Android Version 3.0 for Tablets). Next version is expected to be Icecream.

Samsung is using Android OS in almost all of its Products from Touch phones to Tablet PC’s….in the future it is expected that Android will be the king of all Operating Systems.

I think that the main reason for Android is it being a open Software and many Apps are available….Apps is the main criterion that distinguishes a better phone from the lot.

(1) Apple iOS is a proprietary operating system whereas Android is Google developed open source operating system.

(2) The latest version of iOS is 4.2.1 and Android is 3.0 (Honeycomb) as at today.(Jan 2011)

(3) Both Apple iOS and Android supports Multitasking.

(4) Android has one more short range communication technology NFC on top of Bluetooth.

(5) Apple iOS supports internet Tethering via Bluetooth whereas Android supports with Hotspot via Wi-Fi

(6) Address book share via MMS vcf is perfectly stores in Android with exactly same label of contacts whereas apple iOS doesn’t not support the perfect lebel.

(7) Google Native clients for Gmail,Youtube ,Google Talk,Maps and Search are perfectly designed in Android and Apple uses Apple Mail client to get emails which will not fully support for Gmail features.

(8) Android supports Social Network contact Sync whereas Apple iOS is not.

(9) Skype video calling is supported by Apple and Android.

(10) Viber VoIP Application is only available for Apple iOS at the moment but official site says android in roadmap.

(11) GTalk video is supported by Android whereas Apple iOS does not support.

(12) Both as user friendly and easy to use.

(13) Since Android could be installed on any hardware, so if you want to change the phone or tablet to other vendor will not make much difference is usage whereas Apple iOS runs on Apple devices only.

(14) Patches and bug fixes will be released by Apple only in Apple iOS whereas in Android there are lots of customised versions from 3rd party developers with immediate fixes.

(15) Android can be customised by Vendors or 3rd Party users but whereas Apple iOS is only developed and fixes by Apple. Downgrade is not possible in Apple iOS officially.
