In Pictures!

Go Dutch @ Info Edge!

Its time for some patiala peg!

Pulkit Swarup from Naukri Tech steps in to talk about XMPP - An overview of the protocol. He talks about the current usage of XMPP by various messaging clients and proposals for usage by participating teams for developing new clients.
A nice comparison between OpenFire Vs Jabbered and eJabbered by him shows that when OpenFire implements XMPP to over 96% this is down at 30-40% in case of Jabbered and eJabber.

Next we have Kasa Shirish to compare Android SDK with iPhone SDK. Advatages of using an android SDK over an iPhone SDK is the freedom of use and the open source nature of android. Also the freedom of connectivity with external devices like USB drive in case of android make it a better choice. A nice demo of the Android SDK at least makes me a fan of android! :) Plus its OPEN SOURCE!
That was a good presentation... though stretching a little on time.. but worth each minute stretched...


The next presentation up would talk about MogileFS.. the distributed FS. Taken up by Aditya Seth and Sameer Garg. They talk about the need and use of a distributed file system

Lets get the code flowing... CodeJam....

I wonder on one thing, if its code flowing all around... why christen it as CodeJam?
(I know... might be a bad one... but thats how we are.... atleast the two of us blogging here...)

The code jam is up... and I see 2 good questions.... I thought all this while that it would be tough.... lets see how it shapes up!

With 15 minutes to solve them, here are the questions.....
Problem 1:

Given the Top-Right (x1,y1) and Bottom-Left (x2,y2) integer co-ordinates of two Rectangles parallel to the X-Y axes, Write a program to find the area of the rectangle formed by the intersection of the two given Rectangles.

Note:

• The co-ordinate system is such that x increases from left to right, and y increases from bottom to top.
• If the rectangles are non-intersecting, then the area is 0.
• If one rectangle is contained inside another, the area of intersection is the area of the smaller rectangle. Else If the two rectangles share a common edge and have no common area, then also the area (output of your program) is 0.

Input Definition:

1. On the first line, x1 y1 x2 y2 for the first rectangle
2. On the second line, x1 y1 x2 y2 for the second triangle

Output:

1. A single value representing the area of the intersection of the given rectangles

Problem 2:

Given an NxM Grid (N rows and M columns) find the number of rectangles that are there on the grid. Assume the grid to be having a coordinate system with bottom-left corner as the origin (0,0). Write program to Output the coordinates of the left-top and right bottom vertices of each of the rectangles in a sequential order.

Input :-

value of N and M on the same line, in a file or on the console.
e.g. 8 8

Output :-

(x11, y11) (x12, y12) |--> top left and bottom right vertex of the first rectangle

(x21, y21) (x22, y22)

:

:

(xr1, yr1) (xr2, yr2) | where r is the no. of rows of output (total no. of rectangles).

e.g. for input 8 8 output would be:-

1296

(0, 0) (1, 1)

(0, 0) (1, 2)

(0, 0) (1, 3)

:

(1, 1) (8, 8)

:

(M, N) (M+1, N+1) or (8, 8) (9, 9) | total 1296 rows of coordinates.

Breaking the wall - The First Hammer!

An empty mind is a devils workshop.... trust me... an empty stomach is worse!
We had a break.... and we are back!
Wall Breaker is on and Vikas has flagged it off. His current concern being Boolean operations on Large datasets. He is currently looking at better ways to exclude documents or efficiently run a 'NOT' query.
With suggestions coming in from all directions he should be feeling better! :)
The session ends with no result, but with a better perspective perhaps! :)

The next speaker we have is Manish Gulati from shiksha. Talking about search efficacy he discusses about what is more important as a factor in case of search and search results.
Interesting thoughts I must say!

Software Design Concepts by 'the' Aditya

The next speaker is Aditya Chadha, from Naukri who's here to speak on Software Design Methodology.
For everyone who's never met him, he's one of the best examples of the arguementative Indian.
Aditya unstoppably talks about Design, requirement representation (constraint identification and the likes),Componentization and Orthogonality.

Python Vs Java!

Prasanth Gopinath is sharing his knowledge on Python... comparing it with Java!
With a 'from the scratch' python tutorial he's been discussing various data types and reasons of using python instead of 'java' for the ease of use and flexibility.

Spammers Beware! - Amardeep is here

Amardeep from Naukri Tech dives deeper into Spam Filtering mechanism for emails. He shares knowledge and details on Bayesian filtering methods
for web based applications and mail text. Also discusses about probabilistic analysis of spam classification.

First Deep Dive

The shiksha guys... Puneet Aggarwal & Vibhu Bhushanare here to share the gyan!
Talking about crawlers and extraction using various analysis techniques
viz. Classification models, Concentration Ratio Analysis etc...
Well started... and nicely done!

Opening take

The first Go Dutch event has finally been flagged off!
Hope it goes well!

In the spirit of Go-Dutch : TechWiki and Forum for TechE

two hours to go....!!

Two hours to go and people are just warming up to the thrill of the collaborative tech-event Go-Dutch. Its a Tech Initiative by the Tech people for the The Tech people.
But it seems most people are just busy doing their work, attending meetings, and attending more meetings.

Where is the excitement. Where are the enthu-people?? Or is it just the lull before the storm..!! Are you prepared for the Deep Dive?? Are you preparing for the Code Jam!!???

What does it take to bring out the best of technology, engineering and programming from among the infoEdgians. Who knows? Maybe a couple of brain-teasers or puzzles or solving problems or maybe a chunk of snack (& coffee)!!!

Come on guys (and the fortunate few gals!), let's warm up. let's make this an event to remember. Let's enjoy Going Dutch. :)

Going Dutch!!!

Technaukrat : What happens when great minds are at work???!
Jobseeker : ummm something like -- www.naukri.com, www.jeevansaathi.com, www.shiksha.com, www.brijj.com....

Technaukrat: (smiles)
Jobseeker : And what do they do when they are not working??
Technaukrat : They "GO DUTCH!! "

Welcome to the official blog of 'Go Dutch' - Share the Knowledge.
and in case you do not like the name, I (read that Vibhore Sir) have a Shakespeare quote for you : "What's in a name ? "
Catch all the action live from Ground Zero here. From 'Deep Dive' to breaking the wall. From Code jam to enjoying a strong patiala peg.

Stay connected...Stay Logged On!!!
