Metcalfe's Law

- Metcalfe's Law is expressed in two general ways:

1) The number of possible cross-connections in a network grow as the square of the number of computers in the network increases.

2) The community value of a network grows as the square of the number of its users increase.

The original statement from Robert M. Metcalfe, inventor of Ethernet, was apparently (according to one source):

"The power of the network increases exponentially by the number of computers connected to it. Therefore, every computer added to the network both uses it as a resource while adding resources in a spiral of increasing value and choice."

Metcalfe's Law is often cited as an explanation for the rapid growth of the Internet (or perhaps more especially for the World Wide Web on the Internet). Together, with Moore's Law about the rate at which computer power is accelerating, Metcalfe's Law can be used to explain the rising wave of information technology that we are riding into the 21st century.

Life vs. Blogs....v2

Well if you remember my earlier blog on life vs blogs, i had said that blogs don't let to edit things once blogged. Although this was true for first generation blogs, now days all blogger sites allow editing. I guess they realised that we being humans are so error prone that we always need that second chance. So much for comparison between life and blogs. :-(

Future of Networking: Human Area Network (HAN)

   The biggest challenges with wireless n/wing is that in multi-user scenarios its performance is quite abysmal, in fact the performance is inversely proportional to the no. of users i.e. as the no. of users increases the performance goes down. So how does one counter this limitation? Do we move back to wired commnunication? Didn't we just patronize wireless because wired n/ws are cumbursome to setup and manage plus the sight of zillions of cables is quite overwhelming. Also wired n/wing doesn't sound too well when we talk of 'Ubiquitous computing'.

   Okay here's a hint, imagine if we could simulate wired communication with the only difference that the medium (i.e. the cables) is dynamic in its type of material (i.e. wood, water, pads, etc.) or is the user of the n/w itself (i.e. our body). Research is going on towards developing devices which could be connected simply by touching them or keeping them on a table or on a mat. This is the principle behind HAN or Human Area Network. Infact they are all set to launch prototypes. For a through understanding go thought the following site:  redtacton

My rendezvous with Wireless technologies

    I have always been intrigued with wireless networking and luckily my interests have always been well fed by unintentional events. e.g. i recently bought a compaq laptop (my first ever) which had wifi and bluetooth by default. Being a traditional desktop user these technologies were quite foreign to me and like a true rigid being i avoided adopting these technologies. But for how long??? Fortunately peer pressure forced me to take the plunge and this is what i was able to conjure:

   Not very surprisingly the first technology i embraced was 'Bluetooth'. Actually I am not sure why this was my first choice, may be coz blue is my favourate colour or maybe coz its the latest buzzword in mobile phones. I think later was more motivating. Well i got a friend's mobile phone which was bluetooth enabled and setup a quick n/w and transferred data between my laptop and his mobile phone. Its that simple! With this done i took a step forward and checked out all info on the net. Bluetooth is a promising technology but i was quite disappointed by its distance limitation, althought the idea of a cableless desktop is quite cool i.e. using bluetooth or infrared devices to replace the data and control buses in computers. Nways i moved on the Wi-fi.

   Now Wi-Fi was the real thriller. It did not have any distance limitations (offcourse using repeaters) and was more user-friendly or shall i say more networking friendly. What i mean here is, u could actually buy wi-fi components and setup a wireless network at home.
   My first experience with Wi-Fi was when i used my laptop for surfing in a wi-fi zone. The idea of comfortably sitting on a couch, drinking coffee and surfing was a real treat.
   My second experience was more meaningful and satisfying. Basically i wanted to backup a lot of data from my desktop to my laptop. After evaluating a lot of options i was particularly attracted towards the idea of setting up my own wireless n/w at home. So i went out shopping and bought a wireless usb adapter by linksys for my desktop. After struggling with it for 2 days i was finally able to setup an adhoc n/w and voila!!! Although this might have been the most expensive option but it was truly the most awesome one, worth every penny i spent.

LESSON LEARNT: 90% of the times we refuse to embrace a new technology because of our  Laziness and not because of its demerits, so get up and get going!!

Italians won!!

I know this is a bit late but THE ITALIANS WON THE WORLD CUP!!!!!!!!!!  HURRAHHHHHH.......... and the Germans came 3rd HHUUUUURRRAAAAAAHHHHHHH !!!!

FIFA WC 06

Its been one of the best tournaments so far and if you saw the Germany Vs Italy game, phew..... can't imagine i have to wait another 4 yrs for this event to take place again. Nways there is still the final to be played and i got my eyes and heart set on the Azzuries. Go Italy go......

Ten Commandments of Egoless Programming

A must read for all programmers!!!!

 

what the #$%# is wrong with the formatting??

one thing that i would want to change now is the formatting of my previous post but i just can't....... ;)

Life vs. Blogs

It’s unfair. What you blog cannot be unblogged. Although technically this is a miniscule task to solve I wonder why all blogger sites insist on not providing the delete or modify feature. I guess this is got something to do with the human attitude of wanting to go back and change things once they are done.

To think of it, blogging is almost like life, once done it cannot be changed!! There are so many things in life that you want to go back and change, may be for good or worse but you just can’t. Probably blogs try to emulate the same. They insist that what’s been posted once cannot be modified. This actually can be a good tool for introspection. People do a lot of things on the spur of the moment, right or wrong but at that moment they do things rashly, without thought and it’s only later when the moments long gone and the situation is way beyond control that they try to re-evaluate the implications of their actions.

So let’s try to use this tool to improve ourselves, let’s always try to understand the repercussions of all our actions and let’s work towards getting things right the first time around. Life doesn’t give you a second chance so easily, neither do blogs.

its 'marriage' and not 'marraige' or 'marrige'

NOTE to Self:

1. Never write ur blogs when ur frustrated

2. Type slowly

3. Improve your spellings

4. Stop using copy-paste; they just propagate the error u made the first time



 .... and lastly.....



5. Use spell check, that’s what it is designed for..... ;)

Marraiges

    Today I had to attend a usual cliched marrige. When i got there i was, not so surprisingly, suffering the usual predicament: unknown people, mom introducing me to infinte amount of old people who could barely recognise me but were hyperexcited nonetheless, etc. One strange thing about the entire setup was the mass quantity of Nehru topi clad men, a little snooping around and it was revieled to me that the girl's dad was local politician. Hmmmm.... that explains!!! No wonder immediately after the garlands were exchanged these guys made a run to the food section and picked prime seats in the pangat . Losers!!!

    Nways, even though i hate politicians more than marraiges this is not the time or place to discuss them. Ok to continue my story, so i went on to the stage met the couple, cracked my usual jokes about newly married couples, et al. Down from there, i made a run for the food section ;) (hey thats the only interesting thing to do in such occasions). The plan was to have a quick lunch and get out of the place but plans are meant to be thwarted and thats what my mom did. She met a few other ladies she knew and they decided to chat till eternity.

    Finally after hours of prompting and making funny noises and faces my mom took the hint. Thankfuly after that we had a quick lunch, congratulated the parents, the couples and other hordes of people how directly or indirectly influenced the marraige and made a run.......

    A not so interesting expedition finally came to an end after 3 hrs...
    Long live the tradition of marraiges.....

testing performancing plugin for firefox

Although i have been using a different plugin all this while for updating blogs even this plugin seems to be good enough. Actually the UI is much better.

Need to finalize on either one of these.

Mobile data card

Today i got my Reliance Mobile Data card, another beauty of the wireless world. Frankly i used to get terribly frust when the lights used to go out in the afternoon on weekends. I mean whats the use of a laptop if you cannot browse the internet just because you don't have electricity to power your modem!!

Well now i can actually have some undisturbed browsing time, lights or nolights!!! Thenga to the MSEB!!

quick relook

testing my resolve!! again!!

i am back!!

ok so i am back!!!! Almost after a year!!! Yiiiiippppppppppyyyyyyyyy!!!!!!!!!!

I always knew that i was bad at writing down things, infact i am outright lazy, just can't motivate myself to sit and write stuff and my first attemp at writing blogs just proves that. Nways now i am back with renewed vigor and pledge to update my blog everyday (atleast i hope ;)).

So what brings me back to blog writing and makes me so confident that i will be able to update my blogs regularly. Well the difference is firefox and its amazing blogger plugin. I am totaly in love with firefox - the flexibility and customizability it provides through its numerous plugins is just fabulous. The latest addition to the my collection of plugins is the blogger extension "Deepest Sender". Although it has a wierd name but its quite awesome, the fact that i don't need to go to the website just makes my task easier. The integrated blogger tool is made just for lazy bums like me.

N'ways lets keep our fingers crossed and HAPPY BLOGGIN!!!

Extending utilities of java

This is a good article although the auther doesn't seem to know much about the eclipse movement. With Eclipse all you need is the desire to code in java, the rest of the modalities are well taken care off.

N'ways enjoy the article!

The Java Extension Mechanism by Thomas Künneth -- Java has a huge collection of classes, but many projects need to call upon code outside of core Java, which leads to the question of where to store and how to load this code. Thomas Kunneth shows how Java's Extension Mechanism allows you to make new code available to all Java applications.

My first blog

Well since this is my first blog i won't write much but just reflect over what i have just done (well if you are wondering about what i have just done, then -- MORON YOU JUST CREATED YOUR OWN BLOG!!!!!)
