A lecture series on Analysis and design of algorithms

Just happened to find it on youtube :) .The above set of videos is from the under grad algorithms course offered by Prof. Abhiram Ranade and Prof. Saisundararaman Vishwanathan at IIT Bombay. More subjects here

Bought an Acer 5738 :)

Comes with Linux, 3GB DDR3 RAM, Core 2 Duo T6500 2.1GHz, 320GB hard disk, Gigabit ethernet card, fingerprint reader, an HDMI port (pretty useless unless you have a decent graphics card), multi touch touchpad (allows to zoom using a 2-finger motion), laptop bag, and the usual stuff. More here.
Price: Rs. 34,000

About IIT profs and exams

In my last post, I said that I would post something about SVN clients. Since it's pretty boring, I'll do that some other time :)

Now, coming to the topic, there are different kinds of exams...the general idea is that nothing from the allowed material comes in the exams.

• Closed book: Nothing allowed. The easiest kind of exam.
  
• Open notes: The most common type of exam. We are allowed to take our notes, print outs of slides and a few research papers.
• Cheat sheet: 1 or 2 A4 size sheets are allowed. Contents must be handwritten. The number of sides that can be used is pre-specified.
• Open book: The toughest. You can take any book (any number of books) you want.

There are some other more interesting types. One prof actually had the first 15 minutes of the exam as "discussion time". One is allowed to discuss the answers with the others in the first 15 minutes. But sadly, people discovered that 15 minutes were not enough to understand any of the questions.

Another prof usually doesn't have a time limit on the exam. People come to the exam hall, think....think....think, write whatever they can figure out, and leave when they are too tired to think any more, or just get hungry. And there is a certain prof who said, "Leave the exam hall in <=2 Hours, get 3 bonus marks!"

There are some profs who give "unrelated questions" like "Do you think Obama will be a better president than Bush?", just so that students can take a break from thinking, and relax. These questions, of course, do not carry any marks.

Though weird, the good thing about all these exams is that it's "marks for thought", rather than "marks for how well you can mug or how much you can write".

How to set up SVN

I wanted to set up an SVN server for my project recently. Here is the small script that I wrote for configuring SVN. Just copy-paste it in a file and run it. It'll guide you through the configuration process.
-------------------------------------------

#!/usr/bin/bash

svnadmin create svnrepos  #creates a directory called svnrepos 
#in the current directory, and 
#creates the config files

printf "[general]\nanon-access = none\nauth-access = write\npassword-db = passwd\n" > svnrepos/conf/svnserve.conf
printf "[users]\n" > svnrepos/conf/passwd

while [ 1 -gt 0 ]
do
    printf "Username: "      #create username,password for 
    read user                #whom access is required  
    if [ $user == "q" ]      #press "q" to stop accepting username, passwords
    then
       break
    fi
    printf "Password: "
    read pass
    printf "$user"" = ""$pass\n" >> svnrepos/conf/passwd
done

-------------------------------------------------
To start svnserver,

svnserve -r /users/proj/prashanth.kamle/svnrepos -d

/users/proj/prashanth.kamle/svnrepos is the path of the directory in which the SVN repository would reside (/users/proj/prashanth.kamle is the current directory).

To stop the SVN server, just kill the process (or use the script below)

#!/bin/bash
pid=`ps -A|grep svnserve| cut -d" " -f1`
kill $pid

In my next post, I'll explain how to access SVN from eclipse. Till then, happy subversioning :)

Coolest web app ever

I simply can't wait till it comes out!

Rain ke side effects

Rains are a time when many things begin to happen. Here in IIT Bombay, they start clearing the drains, cementing the roads and tarring the roofs (yeah, you read it right :-P ). Most of the campus goes a nice shade of light green, and the moist soil smells so good. And the best of all, little creatures start appearing. Here is my collection :)

Most of the pics which follow were taken in this corridor which connects the four wings of my hostel

:)

A slug

Interesting colour

What are these??

This one looks like a cross between a grass hopper and a moth

An earthworm. People say they are blind (I mean, they don't have any eyes :) ).

Suddenly popular :)

Thanks to Sree for starting the "Guess who?" contest.
