Hi everyone,
A 100….!!! CELEBRATING A 100 blogs … wooohoooo , I cannot believe I am typing my 100th blog post! Wow my little blog has come so far and I thank you all so much for continuing  to stop by! Without all of the support, comments, shares, hits, everything I wouldn’t have kept Crazylearner going so I thank you!

Today i will show you how can run multiple computers from single CPU. I mean how can you run multiple workstations from single CPU.

You must have heard about desktop virtualization ? If not, i’ll tell you about it all what i know.

There are many approaches to virtualization
Most virtualization technologies are expensive to acquire, implement, and maintain. NComputing is different because we save you money from day one. This desktop virtualization technology allows up to 100 users to simultaneously use a single computer—at a very low cost. I looked for it and came to conclusion that this is one of the best thing which i have came to known recently in computer field.

so what is desktop virtualization? In simple terms it is sharing the power of single cpu with multiple users .It appears to each of the user that he is using his own complete setup including processor .This technology is not new but its availability to general public is certainly new.

Here is simple example to understand how to set up desktop virtualization.

what you are going to need if you don’t want to use desktop virtualization.

11 monitors,11 speakers ,11 keyboards, 11 mouse and 11 cpu

what you are going to need if you want to use desktop virtualization

11 monitors,11 speakers ,11 keyboards, 11 mouse, 1 cpu and 2 desktop virtualization kits (a kit comes with software and hardware and can support 5 users.)

Advantage of running multiple computers from single cpu

You are saving the maintenance and power cost of 10 CPUs.

Typically a user is able to utilize only 10 % of available CPU power . This one kit uses approx 70 % of cpu power among 6 users including the host.

Currently the company which is providing this kit is Ncomputing. For more information and processing related issues visit product guide.

Search Engine for Ethical Hackers

Search Engine for Hackers

A new search engine has been introduced called “SHODAN” that lets you find specific computers (routers, servers, etc.)
using a variety of filters. Some have also described it as a public port scan directory or a search engine of banners.

serch engine hacker

Web search engines, such as Google and Bing, are great for finding websites.
But what if you’re interested in finding computers running a certain piece of software (such as Apache)?
Or if you want to know which version of Microsoft IIS is the most popular?
Or you want to see how many anonymous FTP servers there are?
Maybe a new vulnerability came out and you want to see how many hosts it could infect?
Traditional web search engines don’t let you answer those questions.

Following things could be searched for:

# country: 2-letter country code
# hostname: full or partial host name
# net: IP range using CIDR notation (ex: )
# port: 21, 22, 23 or 80

As we [some of us] can understand, it is very easy to find vulnerable host just by looking at all the banner responses shown by SHODAN.
It could turn out to be a huge threat as many skiddies could be scanning hosts anonymously round the clock for particular exploit or
something that they understand well.

List of Top 9 Dropbox Alternative

List of Top 9 Dropbox Alternative

A reliable DropBox alternative is a great option to turn to especially when you need to create backups and access your important information while away from your PC. Reason behind switching from Dropbox can be it has less free storage , It has been breached by attackers before and security experts maintain it can happen again etc.


List of Top 9 Dropbox Alternative

List of Dropbox Alternative

  • Sky Drive – Microsoft’s re-branding of its cloud storage service “SkyDrive” to “OneDrive” wasn’t just an attempt at catching consumers’ attention by renaming an older service. Instead, it’s an example of Microsoft conceding the “SkyDrive” trademark to another party.
  • Amazon Cloud Drive: Amazon has a huge amount of server space, so it seems a natural progression that it would offer cloud storage. It has earned high marks for its easy-to-use interface and reliability. Initial file-syncing limitations were addressed in an upgrade last year
  • Google Drive – The debutant Google Drive offers the same drag-and-drop synchronization capabilities as Dropbox on the desktop, with clients available for Windows and OS X, but its web portion is more robust than the latter.
  • Apple iCloud – Apple’s iCloud lacks many of the features available in cloud storage services like Dropbox or SkyDrive, but still stands to grab a good chunk of the market for a simple reason: its deep integration with iOS. In fact, almost 70% of the 350+ million iDevice users have access to iCloud.
  • CX: CX offers 10GB of storage for free, double what most of its competitors do. Its seamless user interface has earned high marks, but it doesn’t allow online editing of documents – a limitation for some users who prefer their storage services to include workspaces
  • Sugar Sync – This app similar to SkyDrive has the ability to sync data bits from just about any gadget. And apart from hoarding the lot, it lets you share large files with others who in turn, can either edit the same or simply just view them
  • Box: One of the most popular alternative file storage services, Box includes file-creation features – documents and spreadsheets – similar to G+ Drive. The free version comes with 5GB of storage, but the file management isn’t as smooth, particularly when using the service’s app.
  • A Drive – The developer of this cloud service calls you to centralize, manage and back up your precious files by exploiting all the features embedded here. You can also edit and share documents while accessing the web. Some of the other basic attributes include easy search tool, international character support, remote file transfer and a whopping 50GB free online file storage space.
  • SpiderOak: This is a file-sharing service that prioritizes security above all else. It features encrypted cloud storage, an encryption key for the user, and two-factor log-in authentication. So while some have said it may not be user-friendly enough for novice users, it should satisfy those who know what they’re doing and prioritize security in their cloud storage above all else

We would love your feedback regarding the Dropbox Alternative listed above. Feel free to leave your comments below :) Have a great day!

List of operating systems used in mobile phones

While i searching about some operating system used for hacking then i got a idea to write a post about list of operating used in mobiles. Many of us having vast knowledge about Mobile phones and their features. But very few know about the operating system used in mobiles

So here is the list of some Operating system used in mobile phones

  • Android


Android is the name of the Linux based operating system that is backed by Google and the other members of the Open Handset Alliance. Because of Android’s open source nature, Android based smartphones should be cheaper to produce than those that use operating systems.

And there are various mobile which used this operating system And some top smartphone which use the same platform like Sony xperia , HTC Desite , LG optimus etc

  • Apple iOS

apple symbol

Apple released the iOS operating system which is used in iPhone was launched on 29th June 2007 when the iPhone was developed. Since then there were many updates of iOS and the latest one is the iOS 6. Apple iOS is unique and is only for Apple iPhone & iPad and no other manufacturer can use this operating system platform.

Some of the latest Windows Phones are iPhone, iPhone 2G, iPhone 3G,  iPhone 4, iPhone 4S, iPad, iPad2, iPad3.


  • BlackBerry OS

blackberry symbol

Blackberry OS developed by Research In Motion (RIM) and was released in 1999. BlackBerry Os is running on every smartphone which is designed by RIM and the strange part is that Blackberry OS is totally dissimilar from other operating systems.

Some of the latest Phones are Blackberry Bold, Blackberry Curve, Blackberry Torch.


  • Windows OS

windows-icon-window operating system mobile

Windows OS is widely known OS as this is used in our desktop and Laptop computers but not everyone knows about Windows OS in detail because it is used in computers all over the world, but Windows OS running on Computer and mobile phone are totally different things.

Some of the latest Windows Phones are Nokia Lumia 800, Nokia Lumia 900, Samsung Focus, HTC Titan 2.




Symbian OS is formally the possessions of Nokia. If any company wants to work on this OS will have to take consent from Nokia. Nokia was a leader in the mobile market, so after Java symbian was ultimately widely used mobile phone some time ago when iOS and Android were not in the picture.

Some of the latest Phones are which using above operating system is Nokia E6, Nokia 808 , Nokia 701,  Nokia C 6.




Exactly like Nokia Samsung also has own operating system named as BADA. It was intended for high and Low end smartphones. Bada is a user friendly, effective & efficient operating system, Strange thing is that Samsung do not use Bada OS on a big scale for its handsets instead Samsung too uses Android on a immense scale for some unidentified reasons.

Some of the latest Phones are which using above operating system is Samsung Wave, Samsung Wave2, Samsung Wave3.


Palm OS (Garnet OS)


Palm OS was created by Palm Inc in the year 1996 in particular for PDAs (Personal Digital Assistance) and is used my many huge companies like Lenovo and IBM. Palm OS was originally intended to work on touchscreen Graphic User Interface. It was updated few years later and was able to work with and sustain smartphones. Unluckily Palm OS was not able to do well in the market & due to that it is not being used in any of the latest top devices.

Open WebOS

Open WebOS -logo

Open WebOS or Hp WebOS or just WebOS which was originally created and promoted by Palm Inc in the year 2009 but years later this OS was acquired by Hewlett Packard. At that time this OS was used in several Smartphones & tablets.



Nokia & Maemo both companies came together to create an operating system for smartphones & internet tablets, named as Maemo. Similar to other devices the user interface of Maemo also contains a menu which provides user an access from which the user can go to any location.



MeeGo was fundamentally called as a mobile platform but it was in reality intended to run several electronic devices which includes handhelds, in car devices,

television sets & in even net books. All the devices on which MeeGo OS can operate although have the similar core but difference lies entirely in the interface according to the device.

There are more Mobile Operating systems and if rumors are to be believed then we we’ll be lucky enough to see Firefox Mobile. Android has emerged as an undisputed winner, nevertheless, if we compare in terms of profits & expansion, Apple iOS has emerged as the biggest Tech company which leaves Google Android far behind.
