Last year i attended the same and found to be very useful. Good thing is that you can directly talk and get good suggestions from adobe experts on various technologies like Flex, LCDS etc .

Vacuum is not fully vacuum ?
By definition vacuum is fully devoid of matter right ? But scientists say that the space is always fizzing with photons where the existence of the same is too ephemeral to be captured. Even though they appear very fleetingly these photons emit energy same as of other photons do. So according to Quantum Mechanics and the uncertainty principle, the vacuum so called is apparently not fully vacuum. The result is astonishing because, it points out the existence of friction in vacuum also. It has a got a reverse impact on Newtons Laws of motion where it says, in vacuum there is no frictional force acting up on a body in motion. So the new experimental results, which are yet to be come fully says that a body in rotational motion in vacuum space have to face some frictional force. The stars,planets,moons & dust particles are facing this friction .I wonder,do they stop rotating at some point ? [ courtesy: http://goo.gl/21VZ9 ]

Switching off the Inernet - The Egyptain way !!
Amid spreading protests the Egyptian government has taken that hard step of bringing down the internet across the country by late Thursday. There are a lot of hot discussions are happening around it on human right violation, Government Policies, right or wrong etc etc.. But the wonder to me was how they might have executed this ? Is there a single point of control like a switch, where you can make it off and on ? or do they cut the pysical media ie. network cables? is such kinds of lock-down really work? Burma, China, Nepal like many countries have imposed controls over internet usage in the past years. But none of them was like this - a complete shut down.
According to "Access Controlled" - a book written by MIT people as part of OpenNet Initiative describes two main ways to achieve complete control - one is to switch off the routers which is the traffic gateway to your country, second is to go even one step down and switch off each of the ISP's routers so that none of them can do trafficking. So the Egyptian approach can be either of the two. According to internet monitoring firm Renesys, at 22:34 UTC (00:34am local time), they observed the virtually simultaneous withdrawal of all routes to Egyptian networks in the Internet’s global routing table, leaving no valid paths by which the rest of the world could continue to exchange Internet traffic with Egypt’s service providers. Some mobile services were also got affected. But it seems some of the ISPs were functional, who were providing internet to Egyptian stock exchange. According to the Inernet Society (ISOC), virtually all of Egypt's router were off at the same time, up on this the authorities have reported that they have taken down the Egyptian country code domain name servers (DNS). So none of the domains having ".eg" suffix wont be reachable. But internet traffic through Egypt to the rest of the world is not blocked (Flag Tecom for example) but all traffic that is coming IN to and going OUT of Egypt is being blocked. So this blocking has been done intelligently without affecting the world internet traffic but at the same time isolating the country from outside world by all digital means. So that they could handle the diplomatic and economical pressures from other countries and make it harder for insiders to reach out the world. Though the initial censorship was on facebook and twitter (here) and many of the Egyptians were able to dodge this using tools like Tor,VPSN, Hotspot sheilds, Proxy sites etc, but this final cut has made the end of digital communication to them.
Finally all these remembers me is that as long as these kinda locks doesn't fall on us, the cyberspace is pure democratic. Basically internet is not just me and my friends , my government also matters.

Today i read a news which is emotionally very disturbing. It says each year around 7lakh girls are killed in India, not by somebody else, but their own parents in the very mother’s womb. This is by Satyabrata Pal, a National Human Rights Commission (NHRC) member ( Read ).
Yes of course we can say it's their choice so it's their funeral. But this chilling statistics doesn't mean just numbers to me, its more a mindset of the fellow citizens. We Indians proclaim from the roof tops that we are well ahead in education, in family planning, in adult literacy etc.. etc.. but the kitchen-sink drama is incessantly going. An average joe is still under fallacies that girls are burdens. Or it may not be fallacy rather in all honesty they are under deep water, not able to make ends meet and in addition to it they can not bear a girl child. By the way if somebody asks why this only to a girl is the crack. I feel its due to lack of cognizance from many indirect causes like illiteracy, orthodox beliefs etc.
But this is not just one matter we face. Corruption,terrorism,poverty,over population,urban housing,dowry system,illiteracy like countless numbers of issues. Still at its 63rd year after independence we face these kind of hard nuts to crack the sixty four dollar question to me is - are we Indian’s really progressing or is it applicable only to some (parts) ??
