How to Check Java Documentation of a Class in Netbeans IDE

Recently I have downloaded Netbeans IDE 7.0 to learn its GUI builder Matisse and I was impressed with the changes I saw in the Netbeans from my last use of it in 2007. I was a hardcore Netbeans fan when I was developing mobile application using J2ME and Netbeans integrated environment with WTK, Profiler, and Network Monitor just rocks and on top of that they had conditional compilation feature based on type of platform you   were working like you could maintain your code easily even if you are using device-specific libraries e.g. Nokia UI library etc. Anyway, those were the things of past, what attracted me is the Javadoc feature of Netbeans. Though this feature might have existed long back I have just started using it. Earlier to see Javadoc I used to Google and then go to Sun (now Oracle) website to view Javadoc of any class. While playing with Netbeans I discovered that you can easily Javadoc in the Netbeans IDE itself no need to visit the web.

How to revert back to Windows 8.1 from Windows 10 Update?

If you remember, I have updated to Windows 10 yesterday and blog about the problem I was facing with respect to clarity of text and blurriness on Chrome and Firefox browser e.g. text was turned white to some places and it wasn't pleasant working in the browser. There were few other issues, which prompted me to revert back to Windows 8.1 update, which was the version I was running before upgrading to Windows 10.  Though Windows 10 has lots of good feature in terms of improved search, security and start menu, I didn't adjust it well. Since I don't have time to play around different visual settings and other things, I decided to roll back to Windows 8 version.

How to bypass Websense Internet Filter at Office, School to Access Programming WebSites

Recently one of my readers emailed me that he can not access any .blogspot or .wordpress domain from his office because Websense is blocking them as personal blogs category. Since we techies, often relied on personal technical experience, tips shared by fellow developers for our work, this feels really annoying, but same time it's difficult to convince Websense guys or local Websense security team to not put such restriction. I was thinking about alternative and done some research on the internet, which tells me that you can bypass Websense filter at school or office by using proxy sites, but this idea doesn’t seem good to me, as they may contain some unwanted piece of crap, which is not good for anyone's computer. Also, if you are working for a decent size company, there is good chance that those proxy sites will also be blocked by Websense. This leaves no option at all to access any technical or programming blog, hosted on a free domain like .blogspot or .wordpress domain. That’s why some blogger prefers to have their own domain name than relying on blogger or WordPress.

Is Apple IPhone4S Siri going to replace the Google Search Engine

I am sure this is one of those most optimistic title you can think of but that is what my first thought after seeing apple introductory video of Siri, there new voice recognition and task completion service integrated on Apple Iphone4s. I was amazed with smoothness and accuracy of Siri as shown on that video. You just say siri what's whether, find me new restaurant, traffic status and you get a response you are looking for, this looks to me a new way of searching web and technology.  Asking questions is more natural than typing on Google and believe if Siri kicks of like that you will suddenly have more search volume via siri than google, though only limiting factor is not everybody has Apple Iphone4s with them :). People are also thinking Siri as Google Killer let's see.

Dennis Ritchie, Creator of C language and Unix has passed away

I just come to know about this sad news that Dennis Ritchie passed away, It is second blow to technology world after Steve jobs who has recently passed away. Dennis Ritchie is the first programming figure I come to know when I started my programming classes in C and C++ and that's why when I heard this news I feel sad about it and suddenly I remember my programming days and I thought about this post to pay my tribute and remember him.

There is lot of Great information available on Dennis Ritchie in web and Wikipedia but two of its main contribution is:

1) C Programming language, which is still number one after Java.

2) His Contribution in UNIX Operating System which is best Server Operating system available.

3) Author of book

• The C Programming Language (1978 with Brian Kernighan; see K&R)
• Unix Programmer's Manual (1971)

Let’s remember this programming genius and pay 2 minute tribute to him, without his C language and immense contribution to programming language, community will never forget him.

May god rest his soul in piece.
