free software song

Join us now and share the software;
You'll be free, hackers, you'll be free.

Hoarders may get piles of money,
That is true, hackers, that is true.
But they cannot help their neighbors;
That's not good, hackers, that's not good.

When we have enough free software
At our call, hackers, at our call,
We'll throw out those dirty licenses
Ever more, hackers, ever more.

Join us now and share the software;
You'll be free, hackers, you'll be free.


the power of pervasive computing

i attended a workshop on multi-core architecture in my second year wher i was exposed to few interesting fields of research.though they focussed on multi-core architecture,programming and hardware technology,etc
i understood that all these things focussed on only one thing-connectivity.
i saw few videos in which they exposed few devices which used intel multi-core and all were connected to each other..
to be more clear i can giv a small scenario ..its like wher u turn on ur a.c before u come home jus by sendin an sms,u control ur washing machine from ur mobile soon as u enter home ur tv starts an interactive application asking u for ur favourite program..gettin share market status on ur mobile phone,etc,etc
it was all good to see but i was wondering how these ppl managed to provide connectivity betwwen these many devices.
this field of research is called pervasive computing and in some areas refered to as Ubiquitous computing.

there is a lot of research work going on in this field..and lot of new innovative ideas are turnin into reality..
my final project which contained 11 modules had 5 modules which come under pervasive computing..but i was not aware of the fact that i am workin on pervasive computing :) actually i was trying to control a comp or laptop using a mobile which i actually emulated the dos environment on the mobile screen and it was wen talking about the use and need of an application like this it is really really useful cos this application can be used from nywher to anywher..

a whole lan or wan can be controlled just using a mobile phone..jus imagine tat once u get an access to a network u can control it ,download files from any of the comps,etc or turn bad and shut down and destroy the whole network..

hhmm..destructive ideas apart..

few days back came to knw that in japan a robotics company hav managed to provide connectivity between a robo and a mobile phone as a result the master of the robo can giv instructions to it from wher ever he/she is..

mostly i wud hav been a gprs/wap connectivity bcos no other wireless protocol is so pervasive(upto to my knowledge)

but how come they managed embeddin a gprs device in a robo..wat an innovation..check this out in

we can keep discussing things like this wen it comes to pervasive computing..ther r a lot of things tat we can achieve and implement in this field and as a result life becomes more easy..

not only for a luxurious life..this technology can also be implemented for the physically disabled ppl..and in agriculture ,business,etc ,etc.. my brother once attended a conference organized by tcs in pune.and it was addressed by
many great researchers from microsoft,etc..and also the algo geek c.a.r.hoare(quick sort).. on his return my brother discussed with me ,the various projects going on in this area and almost all the projects wher been carried out for a social cause.. i was very much surprised by the projects he explained realized the power of engineering....
one for farmers,a project for blind ppl,a proj for poor school children,a project for naive computer and calculator users,etc..

and to conclude i wud like to throw some light on the percomp project which is been carried out in the Embedded Systems and Pervasive Computing Lab at Federal University of Campina Grande.
