| I love to write tutorials. They provide a wonderful way to share
confusion. Whenever I am sufficiently confused about a subject, I
write a tutorial on it. My tutorials seek to convince the readers
that they are not the only dumb people out there.
The current tutorial topics are
- Assembly language:
A tutorial on 8051/52 assembly language built around an online simulator.
- Cryptography:
A brief inttroduction to some computional number theory needed in
cryptography. Also features a cryptography calculator for
modular exponentiation etc and Jacobi symbols.
- Some computer hardware
stuff:
This is a tutorial to teach you how a computer hardware works. It starts
from the absolute basics like gates, and works its way up to making a
real functional computer using the URISC technology.

I live in the City of Joy, which euphemisically refers to the
overcrowded, hot, humid, polluted and dusty
city of Kolkata. Little wonder, that I love to get out of the
city, whenever I find time (which is increasingly decreasing these
days!). Everytime I leave the city, I plan to write a
travellogue. As a rule, I do not usually find the time to
execute the plan. Here are a few exceptions to that rule:
- Pelling: A little
township in Sikkim.
- Asansol: No
self-respecting tourist map would give a place of honour to this
dusty and dingy city. But still it was an enjoyable trip.
- Bhalopahar: A
man-made forest in Purulia.
- Purulia: A trip to
the Matha mountains in Purulia with students.
- Sankarpur: So near
Kolkata, and yet so far from the madding crowd...
- Bura Madmaheshwar: A very
enjoyable trek to Bura Madmaheshwar in Uttarakhand.

By education I am a statistician. Ever since my higher secondary
days and all throughout the B.Stat, M.Stat. and PhD years, I have
been doing statistics... learning, teaching,
applying, and even earning money out of this
worse-than-damned-lie. Here are some notes that I have produced
from time to time about statistics. All these were written to
teach statistics to various groups of students.
- Nonparametric statistics:
An introduction to classical nonparametric statistics (
sign test, run test, chisquare test etc).
- Computation-intensive statistics:
A brief introduction to concepts like bootstrapping,
cross-validation etc.
- Design of experiments:
A few pages devoted to factorial experiments and the splitplot design.

An interactive map of Salt Lake:
Salt Lake is where I live in Kolkata. It
has the rather diconcerting feature that every part of it looks exactly
like every other part, making it an ideal maze even for people
living there for years! The roads do not have names (actually
some them do, but they are zeolously guarded secrets). People refer to
places vaguely like "the third large bend after the small red
house ignoring the small bend in between". After getting lost a
number of time in
the maze of nameless roads and clueless residents, I decided to
make a little interactive map of my own.
