What is Open Source?

We can say that, the opensource means the software may contain the source code, which is the very necessary thing. We cant say that the software which are freely available are known as open source software, in opensource s/w the licencing is the very important thing.

So conclusion is that every open source s/w is a free software, but not every free s/w is an opensource s/w.


The main reason of licensing is that, the s/w is freely available, and anyone who want to customize the s/w for their purpose they can just do it by their own. This is the main key feature of open source software.

opensource is advantageous it is just matter of applying some logic. After all one of the central idea or s/w already there, why you should make again or reinvent again. All the s/c is available you just give your some effort and make the s/w very effective, then the end result will be better, So there is no point of reinventing, if it already.

50 Essential Skills Every Geek Should Have

The highest echelon of geeks will be able to do everything in this list, and this is by no means a full categorization of the complete geek skillset – only what we consider to be the most indispensable abilities. Have anything to add to our list? Post it in the comments!

Name These Connectors!

Finding hidden hardware gems in bins of archaic cards at computer shows and swap meets is an ever-so-crucial nerd skill. Frequently the only way to discern the difference is to do an on-the-spot ID of the edge connector. True nerds should be able to identify even the most esoteric connector in their sleep (if they sleep with their eyes open, that is). Can you separate the crap from the kick ass? No cheating!
A. PCI-Express connector
B. DDR memory
C. Dual-channel RIMM

Run All Your Essential Apps on a USB Stick

Any real nerd is almost sure to have a USB thumbdrive in his pocket at all times. After all, USB flash storage is pretty much the best way to keep data conveniently at hand. What the average nerd might not know, however, is that it’s possible to install all sorts of apps on a thumb drive, meaning that you can use your USB stick as a mobile platform for your browser, email and instant message client, office suite and more. That means you can access these programs, settings intact, from any computer with a spare USB slot.
It’s all made possible by PortableApps.com, an open source platform for portable software. To get started with PortableApps, go to this page and download whichever version of the portable suite suits your needs. Then run the installer, and choose to install to the root of your USB drive. In the future, if you want to add additional portable applications just download the app, then select “add a new app” from PortableApps’ options menu and browse to the .paf.exe file you downloaded.
Right now, there are portable versions of heavyweights like Firefox, Thunderbird, and OpenOffice, as well as a whole ton of other, awesome programs.

Top 10 mistakes of Bill Gates

Bill Gates is considered as a great man. Many people look up to him. And a lot of people are inspired by his life. But then again like any other human being he also has his own mistakes. Here are the top 10 mistakes of Bill Gates.

1. The man created a software monopoly and in return he got so many lawsuits for it.Bill Gates is still fighting with lawsuits.The source on wikipedia clearly stated that
   

   United States v. Microsoft was a set of consolidated civil actions filed against Microsoft Corporation on May 18, 1998 by the United States Department of Justice (DOJ) and 20 U.S. states. Joel I. Klein was the lead prosecutor.The trial started on May 18, 1998 with the U.S. Justice Department and the Attorneys General of twenty U.S. states suing Microsoft for illegally thwarting competition in order to protect and extend its software monopoly.

2. Bill Gates did not consider opensource. His business strategies always counter opensource principles and paradigm.You may be interested in his open-source debate In a Fortune magazine he clearly says that
   

   It’s easier for our software to compete with Linux when there’s piracy than when there’s not.

3. The Windows OS made Mr. Gates the richest man in the world. But its latest iteration is bombarded with lots of negative criticisms.
4. He allowed Windows Mobile to happen. Did he run out of innovative ideas so he settled for a miniature Windows OS for mobile phone. He could have put up a team to design the OS from ground up.
5. He let DOS die. It was a promising OS and a very stable one.
6. Bill Gates did not think of cloud computing probably because of his proprietary Windows OS. But this is definitely one of his biggest mistakes.
7. He allowed Windows Millennium edition to be released. The OS was definitely a reflection of the lack of talents from Microsoft. It failed the expectation of the people. It was premature.
8. He ignored search. Look what happened to Google now. Bill Gates already made some moves about search in the end of the 90s and it was definitely a mistake to trash it.Scobleizer once revealed in his post that

   Look at my last post. Now read this one over on LiveSide. It’s a short report that Microsoft executives are bragging to MVPs that “we’re in it to win.”

   I don’t think Microsoft is. The words are empty. Microsoft’s Internet execution sucks (on whole). Its search sucks. Its advertising sucks (look at that last post again). If that’s “in it to win” then I don’t get it. I saw a bunch of posts similar to the one on LiveSide coming out of the MVP Summit. I didn’t post any of them to my link blog for a reason: All were air, no real demonstrations of how Microsoft is going to lead.

9. The Microsoft Zune is a mistake. A lot of money poured into its development but yet it did not yield enough profit.John Biggs from Crunchgear had a poetic post on “Who killed Microsoft?”.Some of the extract are as follows:
   

   Who killed Microsoft? Why did all those jobs get lost?

   “Not I,” said the Zune fanboy, “I got Zune, I’m no iToy Sure it didn’t do too much and too bad my girlfriend bought a Touch now we’re iTunes all the way what else do I have to say?”

10. The Xbox on the other hand is too pricey for a gaming console and because of this; people go for other brands- the cheaper ones.This is only reason why Xbox price set to drop in war with  Sony’s PS3 and Nintendo’s top-selling Wii. Those are the top 10 mistakes of Bill Gates. These might be some of the negative side of the guy but these will never take away his greatness.

Software: Trojan Remover v6.7.5.2558

 

Trojan Remover v6.7.5.2558 Mediafire links

Trojan Remover is designed to automatically remove malware (trojans, worms, adware, spyware, etc.) from a PC when standard anti-virus software has either failed to detect the malware or is unable to effectively eliminate it.
Trojan Remover can detect and remove malware without the user having to manually edit system files, including the Windows Registry, and all without using SAFE mode. New malware files are found daily. Many of the newer trojans, worms (and some Spyware) use rootkit techniques to hide their presence. This means that the files are not visible on the system.

Software: Password Door

Password protects programs on your computer

•  Add passwords to programs on your computer.

• Users must enter passwords in order to use protected programs.
• Protect your privacy by adding passwords to Outlook, Word, WinZip, Media Player, AcdSee...

Password Door can add the password protection feature to any program on your computer. It will not modify the original programs, so it will never destroy the programs and you will never lose data.
There are a lot of fine software installed on your computer, you know them well: MS-Office, WinZip, Windows Media Player, Real Player, AcdSee, Outlook Express. Most of them have no password protection, so anyone who shares your workstation can launch one of these applications and use it to browse or modify your data that was created by it. You don't want to have to learn to use new software that have the password protection feature, but you do want the password protection feature for your existing software.
Now you can use Password Door to add password protection to any software. When software is protected by Password Door, anyone who wants to use that software must enter the correct password in order to launch it.
This is a program that you lock programs with a password of your choosing!
I hope u  all like it!

Jolicloud: The Operating System Download for Netbook

A netbook is not a laptop. It is smaller, less powerful and considerably cheaper. This isn’t to say a netbook is inferior to a laptop; on the contrary, I use my Eee PC more often than any other computer. I mean only to say that a netbook is different than a laptop, and as such should be used differently.
It’s for that reason I’m not interested in using an operating system designed for desktop computers – such as Windows or Ubuntu – on my netbook. I want something designed to do what netbooks do best – access the net – but which also allows for some flexibility. I want a system optimized for netbooks that’s easy to install and set up. I want my netbook to work, consistently and quickly.

Jolicloud, however, is the real deal. It exists in a world where desktop applications and web apps are on the same level, and it does so with style. Best of all, it’s extremely easy to use.

Why It’s Cool

At first glance, regular Linux users will think the Jolicloud operating system download for netbook looks like a skinned Ubuntu Netbook Remix. Jolicloud is based on Ubuntu Netbook Remix 9.04, and Ubuntu users will certainly feel right at home, but Jolicloud’s got more to offer than just a new color scheme.
Jolicloud’s mission is to build an operating system completely optimized for netbooks. This is made evident by the system’s optimized Linux configuration, designed to get the most out of netbook hardware. Also, the programs offered are lean to begin with, and then tweaked to run quickly and best make use of a netbook’s limited screen space. For example, here is how Firefox looks out of the box on Jolicloud:

As you can see, the top of the window is integrated into the top toolbar – a tweak Jolicloud inherited from Ubuntu Netbook Remix. That’s not all, though. The “File Edit View” toolbar is gone, replaced by a single arrow to the right of the search box. The statusbar disappears until you start loading a site – an interface idea borrowed from Google Chrome.
All of these tweaks are designed to save the netbook user what he lacks most: vertical space. This means there’s more room on the netbook’s small screen to look at content, as less is used showing toolbars that aren’t absolutely necessary to have on the screen.
Such tweaks are subtle, and the user could obviously do these things themselves with Ubuntu or Windows to create their own perfect netbook operating system. But they don’t have to, because Jolicloud exists.

Application Manager

Perhaps the greatest thing about Jolicloud is its application manager. Hundreds of free apps are available, and all can be installed with a single click.

To install any of these programs, the user needs only click the “Install” button beneath them. It’s that easy.
You’ll also notice Gmail, Google Maps and Facebook are listed here as applications. Many of the applications available to Jolicloud users are, in fact, websites – fitting for a netbook operating system, and quite savvy when you consider the way people use computers today.

Web Apps

A lot of the websites most people use every day – including Gmail, Remember the Milk and Google Calendar—are better thought of as applications than they are websites. Gmail, for example, is a complete email interface (and an extremely powerful one at that.)
Such websites-as-applications are so common on today’s Internet that we even have a term for them: web apps.
Jolicloud offers hundreds of web apps in its application manager. Install these and those given web apps can run in their own window, apart from your browser.
Check it out:

Here you can see the Gmail app opened in Jolicloud. As you can tell, it’s basically a full-screen browser, sans toolbars or controls – that is, it’s Gmail as though Gmail were a program and not a web site.
It sounds useless, but it’s not. The vertical space saved by leaving out the various toolbars means you’ve more room to use Gmail for reading and sending email. Since everything you need to use Gmail is included in Gmail itself, however, you won’t miss the flexibility of a browser.
Best of all, if you click a link in an email it will open in your browser window, leaving your Gmail window running Gmail.
What I really love about this approach is it means I can use my browser just for browsing. As an avid user of Google’s various offerings as part of my work flow, I always have a Gmail tab, a Google Maps tab and a Google Voice tab open on my browser.
Not anymore. Now I leave those programs running as separate web apps, meaning that when I’m researching an article or troubleshooting a technical problem I can focus on the task at hand: browsing.

Compatibility

The Jolicloud team lists all compatible hardware on its website. If your netbook is on that list you can expect full, out-of-the-box compatibility. If not, there’s a good chance Jolicloud will still work for you, and the team always appreciates learning about new models that work. Give it a shot either way.

Download Jolicloud

Installing the Jolicloud operating system download for netbook is easy. If your netbook runs Windows you can download a single executable – run it and Jolicloud will install like any other application. This is a great way to try out this new operating system
. Download the Jolicloud installer for Windows here.
Alternatively, you can download the ISO file. Jolicloud even provides an easy-to-use program that can copy the image to a flash drive—though be warned, the program deletes all data on your flash drive. Download the Jolicloud ISO and image-writing software here.

JAVA-----

we already know that java is the platform independence programming language.....why? need to know...
so first of all i want discuss that what is the the meaning of cross platform....
It is a quality or feature of an particular application or multiple application which can be easily implemented on other computer platforms.

Two types of cross platform

1. Which requiers some building block or called as compiler
2. Another one is which doesn’t need any thing and run without any preparation

why c/c++ is not a platform independence language.....

Platform independent means the execution of the program is not restricted by the type of os environment provided

Java is a platform independent language becoz of the bytecode. In java, when we execute the source code...it generates the .class file comprising the bytecodes. Bytecodes are easily interpreted by JVM which is available with every type of OS we install.
Whereas C and C++ are complied languages which makes them platform dependent. The source code written in C / C++ gets transformed into an object code which is machine and OS dependent. That's the reason why C and C++ languages are termed as Platform Dependent.
