Learning and Memorization

Got thinking with this old article on wired: Want to Remember Everything You'll Ever Learn? Surrender to This Algorithm


I have recently had trouble remembering things because of my interest in so many fields. This looks promising as a strategy to learn more and more.

Excellent quote from above article:
"You must clarify your goals, gain knowledge through spaced repetition, preserve health, work steadily, minimize stress, refuse interruption, and never resist sleep when tired. This should lead to radically improved intelligence and creativity. The only cost: turning your back on every convention of social life. It is a severe …

My Library At Google Books

Today I created my own library at the Google Books site. Its publicly accessible at Abhishek's Library.

I have added some of the books I recently bought to the library. Some comments/observations about the service:

  1. The "Import Books" feature is excellent. It uses the ISBN number to look for books and add them to your library. But, it failed to find some of my books. These I had to add using the book search option.
  2. The following two books, I could not find even after a search.

97801433335818 The Exploits of Professor Shonku
81-87-98118-0 The Best of Saki

The lisp of life

stretching abstraction very far.... at any moment in time (say t), one could think of one's life as a cons pair of time gone by and the future.

such that:

(car life) -> past
(cdr life) -> future.

(cons past future) -> life

and now at the time t+1, one could recalculate life as
(cons (+ past 1) (- future 1))

if expected age is a constant *FULL-LIFE*, then in the beginning we are
(cons 0 *FULL-LIFE*)

and in the end
(cons *FULL-LIFE* 0)

and mid-life crisis is when
(eqlp (car life) (cdr life))

lambda-tube v0.1a Released

I have been working for the past month on an application to search and download videos from youtube. This application now has most of the featues that I had initially planned. In the spirit of “release early release often”, I have released an alpha verson of the software. You can get it at

A little about why I wrote this program. It is actually a coming together of a few favourable factors.

  1. I have been learning Scheme through books like “Structure and Interpretation of Computer Programs”, “The Scheme Programming Language” etc. In learning every …

Learning the "Programming Language Scheme"

Learning the "Programming Language Scheme"

Recently I began learning the how-to program in Scheme[]. For the reader it might be interesting to note that I already program in Java, C, and Python. In the past I have also programmed in C++, Pascal and BASIC. Learning at least one dialect of LISP had always been on top of my TO-DO list. I had seen some LISP in action during my college years as part of the "Programming Languages" course, but never learnt it fully.

I finally began this endeavour after having read "Paul Graham's" essays on LISP and programming …
