Why is social networking important?

 Hello folk, we meet once again, with something little non technical today. Yes, you are right, today we are going to discuss the importance of social networking in our day to day life.

I wonder how our life is changed these days by websites like facebook, orkut, twitter etc. These websites have become an integral part of our lives. These websites help you stay connected with your friends, colleagues, old school-mates. These giants are now a days called social networks.

I go to office in the morning at around 9. I always stare at the advertisement of Aircel which I get to see on the way down to my office, shown in the picture below.

      The mobile telephony service provider Aircel, and might be many others, are taking help os such socail networking websites to reach a more customers, promote their products and harness the potential of social networking.

      I can explain you all this in simple words. Take this situation, I write a blog post here at the4thdimension. I embed some code so as to publish the Facebook like button at the bottom of this blog post. Then some visitor, say 1 of 10 likes this blog post. The like appears on his wall which is then seen by others. The other people in his connections come and read this blog post. This is how I get more visitors. The same way companies like Aircel, Engadget, TechCrunch and many more make use of social networking websites to promote their services and products.

  Thanks for reading.
  Keep visiting.

Are desktop computer applications dead?

The answer is certainly, NOT. The desktop application are not dead yet, neither are the desktop computers. But what hard core desktop application programmers need to turn their attention to is, to begin thinking and coding the desktop application which will harness the multi-core processing power of the CPU.

   The processing power of the CPU has been increasing as never before. In the earlier days it used to be a single CPU pushed strongly into the mother-board of the desktop computer. With the passage of time, advent of new technology and enhancements in the chip fabrication technology, engineers have become capable of embedding 2 or 4 CPUs on a single substrate of the chip.This used to be called as the spatial placement of the CPUs on the chip substrate. Now a days , what engineers do is they place the CPUs over other CPUs. This has led to spatial as well as vertical expansion of the chip substrate. This has enabled us to pull the number of cores on the CPU from 2-4 to 8 or 16. Withing few coming years, the CPUs with 16-32 cores will be available in the market. So in order to be always one step ahead of the technology, a programmer has to take into consideration the number of increasing cores on the CPU and write his application accordingly.

  The application should be multi-threaded, parallel processing or a concurrent application. Such an application will harness more computing power of the CPU and the probability of the CPU to stay idle will be reduced.

The following facts from some of the renowned technology websites are evident of what I have already mentioned in the above paragraphs.
So I think as a desktop application programmer, everyone should code a multi-threaded application. Be it a sky fire desktop game or a text editor, there is a high chance that you can leverage the multi-threadeding capability into your application program.

BSNL 3g internet speed review

Just a few days before I got to use BSNL 3G internet. I used it for over 10 hours in a time period of 4 days. I was quite impressed to with the experience I had while using 3G internet. For internet addicts like me, 3G seems to be a boon. The speed is awesome, very unreliable though.

The following snapshots have been taken at different instances of time.

Creating a Download Manager in Java

Hello folks, I am back here again...!
Being a Java fanboy, I keep myself indulged with writing some sort of applications or code snippets in Java in my leisurely time. During last few months I have been working on this Java download manager...Its nothing but a simple program having lots of classes and files etc.

Java Swing download manager
But most importantly, there are many threads of program execution.This download manager is not a kind of some professional software, its simply a single segmented multi-threaded download manager. Multi-threading being one of my programming manias as foretold on my About Me page. The whole download manager is based on  just a following Classes in Java. Though I have added some more classes to create the Software Application user interface(UI) in Java.

Creating an URL object
Getting URLConnection object from URL object
Getting InputStream object from URLConnection object
Then reading the InputStream as usual

/*A simple algorithm to read and write the downloaded  file to the local disk.*/
  FileOutputStream fos;
  InputStream is;

   With the above code the file located at a specific URL is downloaded and saved to the local disk. I have packed the whole simple read-write program into Java Swing desktop Application. This way I also got to learn a little bit of a Java Swing API.

  The following screen-shot depicts the program activity on the console or command prompt.
Console Output

I believe and assure that this is a software written just out of interest, but your comments and criticisms are always welcome anywhere on The4thdimension.

Nokia C6 did not stand to the expectations of its users

      Hello folks, I have recently noticed that Nokia C6 did not perform well in some of the aspects like battery, OS stability. The stability of the Operating System of any device is a concern of utmost importance. If the OS of the mobile is not stable, I just dont understand how do these vendors sell such devices.

1. It was around a couple of weeks before that my mobile had suddenly restarted for no reason and without expectation. When it settled, I found that I have lost all my messages that I had stored in the memory card.
Thank GOD, I did not have any important data in the message inbox of my mobile.
After this mishap occurred, I have started storing all my messages in the phone memory. Lets hope that safe now.

2. Another anomaly I noticed with Nokia C6, was its battery. Earlier when I used to charge the battery completely it used to run the mobile for more than 2 days. Now I have noticed that when I charge the mobile, the battery drains off within 1.5 day. 

Fully charged battery at night.

Battery drained one-level just in 8 hours of stand-by
 The above incident is really ridiculous. Something that used to take about a day to happen, is happening in just 8 hours. This simply means that the performance of the battery has degraded.

So I suggest that DONT GO FOR NOKIA C6, rather go for some Android Device. The Android Operating System is fairly stable and has very little to no issues.

So I want to ask Nokia, if this is something they wanted to sell to their people, who always trusted them and that too at such an alarming time of Mobile OS wars.

Dell service/support in India is awesome.

Hello all, the cyber organisms. I am here with a very good news as well as a bad news for all the Dell product users. I had just bought my Dell Inspiron 1440  in Feb last year.

  Since many days I have been facing a problem of slowly running laptop. I was totally annoyed with it. Recently I discovered that my hard drive had got some bad sectors. I was surprised to see it because my usage of laptop is very good. I never let it run for a night long, neither do I use it roughly. But then I had found that this had happened to my laptop. I was worried about taking back-up of all my important data onto DVDs and friends PCs.

   And then I directly called up Dell Customer Care on 18004254051(toll free) yelled at them "how did my laptop face such a serious problem within an year of purchase and I have already faced a battery problem earlier". They just calmed me down, took down the error code that I got while carrying out a memory test in BIOS and took down my address. Then within 2 hours I got another call from Dell for taking my appointment to get the hard drive replaced. In the evening I got another call for confirmation of my address. I was told that the Dell Engineer will come the other morning at 11.

     I just spent the whole night taking backup of my important data. The Dell Engineer showed up in the morning sharp at 11 am and I got the faulty Western Digital hard drive replaced with a brand new Toshiba.

So in all, I would like to appreciate the support and service that Dell provided me for the defects I have faced with the battery and the hard disk within 24 hours.

Technology predictions for 2011

       So once again we come back to our tech talks on the4thdimension. With the arrival of new year, there are a lots of talks going on in the market about business trends in 2011, economical ups and downs that will occur in 2011 etc. but as you all know, my taste lies in the Trends in technological advancements in 2011. I just came across these discussions about the ups and downs and new arrivals in technology in 2011.

   Here are some key issues that need to be addressed while considering the technological prediction for 2011.

1. Mobile Computing : With the advent of high speed networks like 3G and 4G, there will be a boo of web usage on the mobile devices. In India around 40% of the internet users use mobile devices to surf the web, hang out on social networks and e-mail access. With the release of Google's free and open source mobile operating system Android, the world will see the face of day-to-day life into mobile phones. Mobile payments, video calling, sophisticated apps to use on mobile phones have made the life comfortable. Many big players like Samsung, HTC, Motorola and beginners like Intex and Micromax Informatics, India have already climbed up the Android bandwagon. This wild-fire that has been set up by Android and iPhone will continue to rise in 2011. The mobile phones are the future of computing.

2. Cloud Computing : Referring back to what has already been mentioned, 3G and 4G networks have facilitated high bandwidths for individual users. For advanced internet users, half of the time of the day is spent online, people are shopping from their personal computing devices, GPRS seems to have gone. Cloud based services like Gmail, DropBox have become emergent, concepts like PaaS and SaaS have evolved. Network based PCs like Google's Cr-48 has got momentum in research. 2011 will add fuel to the fire, giving rise to competition in network based application and computing.

3. Concurrent Programming : I did not see that wildfire for concurrent computing has been set up in the arena yet. As far as I have researched the technology using internet, technical news and articles etc, I believe 2011 will trigger an era of Concurrent Applications to be developed. I can support my view for this by stating two things.
 Supposedly by the end of 2011, processors with more than 4 Cores will begin to ship out. The computing work assigned to the CPU will prove to be far less than the computing capabilities of the CPU. The computing paradigm will change its face.

Facebook tops the list of Most Visited Websites in 2010

    A very happy new to all my beloved readers. Its been a good year 2010 for my blog just coz I registered my own domain name for the blog
    While having my morning coffee, somewhere on the internet, I just read that Facebook is the highly visited website of the year 2010. I already have discussed the way Facebook took down orkut .

    Having your profile on a social networking website is great. I have also noticed that some start-ups and organizations have realized the power of social networking. They are now planning to release their own small social networks for their customers rather than having discussion forums to discuss reviews of their products, connect with each other etc. This also makes me wonder if Web 3.0 will come up with companies having their own individual social networks. The discussion forums will have gone soon.

   The Social Networking Giant Facebook has topped the list of the highly searched items. It has rendered Google on rank no. 2 in the list of the highly searched items on the internet as reported by

           So I wonder that after Facebook took over Orkut and other famous websites and Social Networks in almost all the countries, is it now the turn of Google, the www Goliath, to be superseded by David in the name of Facebook.
