Photos : Venus Transit

Finally witnessed the long awaited Venus transit. Few of my Astronomer and Photographer friends gathered together before sunrise and enjoyed the rare view. The view was initially bit blocked by the clouds adjacent to east horizon but it became crystal clear afterwards. Following are some of the pictures taken by my friends.

Upcoming Venus Transit

As most of you would know tomorrow's sunrise will be special. No, the sunrise will still happen in the east direction :) but it will rise along with planet Venus, right in front of it. Sun will rise in Hyderabad around 0542 Hours, the transit would have begun by that time. The transit will continue till 1001 Hrs. Me and few of my friends are will be hoping for clear sky so that we can view through out solar glasses and capture photos using solar filters.
Sun filter glasses for safe viewing

Following is the schedule of this transit

While its highly recommended that you gather a pair of working solar glasses and go out
and watch the transit as it is last of our life time. The last was in 2004 and next one
will be in 2117, there will be some virtual ways to watch it as well in case you are traveling or do not find any gears in this last moment.

I leave you with a picture of sun taken with my camera of course with solar filters gifted by my colleague and fellow astronomer Nikhil Tungare , who himself shot couple of beautiful images of sun with very prominent sunspots just few days before the transit event.

IEEE : World of Web Apps Session

Last Saturday IEEE GOLD of Hyderabad Section organized the World of Web Apps Session at Progress Software as part of our developer community initiative . This session was for engineers who work on open source web technologies and have interest in the same.

IEEE GOLD World Of Web Apps

Shabda from AgileIQ talked about meteor js and highlighted that it can connect directly to mongodb from the client side itself. Object subscription, Data synchronization and hot code pushes are the interesting features of meteor js. He shows us the company popularity demo where every attendee could open the page in in their devices and vote for websites. Instantaneously  this vote was updated in the server and all other clients. offline devices also could vote and it got synchronized once the device came online. It uses webrtc for the latest browsers and long poling using AJAX for others. Meteor js application can be directly hosted at or exported to node.js application for self hosting.

Amgonna co-founder Niranjan spoke about MongoDB which is a leading NoSQL databse. It is very trending technology given the fact that it can handle huge amount of data with high availability. He also explained that its a young community and yet to go through enough research. Lack of documentation and support may force developers to struggle bit more. Lack of standards also may cause portability issues but in terms of scalability it may beat any RDBMS software.

Medical transcript writer turned software engineer Udaya spoke about how he choose combination of various open source web technologies for his projects. He built and uses Pyramid as it is a good choice as python framework for flexibility.

Finally Charan talked about very popular Node.js framework. He encouraged people to get involved in his open source projects and fork his repos from github

We sincerely thanks Progress Software for hosting this event in their excellent facility .
