Amazing Machine Learning in 1950!! 

Watch this excellent videos from the 1950’s that demonstrates machine learning. Amazing!

Learnt about this from the book on Bell Labs that’s one of my top recommended read for anyone.

Matter, Energy, Time, Space and Programming

Was reading C++ in Action and came across this .
What’s the most important thing in the Universe? Is it matter? It seems like everything is built from matter-galaxies, stars, planets, houses, cars and even us, programmers. But what’s matter without energy? The Universe would be dead without it. Energy is the source of change, movement, life. But what is matter and energy without space and time? We need space into which to put matter, and we need time to see matter change.
Programming is like creating universes. We need matter: data structures, objects, variables. We need energy–the executable code–the life force of the program. Objects would be dead without code that operates on them. Objects need space to be put into and to relate to each other. Lines of code need time to be executed. The space-time of the program is described by scopes. An object lives and dies by its scope. Lines of executable code operate within scopes. Scopes provide the structure to program’s space and time. And ultimately programming is about structure.

Great Strength

As Elbert Hubbard said “It does not take much strength to do things, but it requires great strength to decide on what to do”.
Similarly in equity investing, it does not take much to trade, but it requires a great strength and patience to decide on what and when to trade.

From birth of transistor to tell tale brain

In the last post I listed my reading list for the year. Someone asked, which books will I recommend from this stack?
The books that come to the mind are…

1. The bell labs

Engrossing account of the birth of transistors and otheri bell lab inventions. Loved the way how the chapters were framed and how each was organized. 

2. Gun germs and steel

Long book but fascinating in many ways. Takes you back in time and unfolds the history bit by bit. Highly recommended. 

3. The tell tale brain

Another fascinating book. I thought I knew enough about the brain and this book explained everything I knew with a neurological twist. Loved it. After reading this you will never see brain with the same eyes. 

4. Survival of the fittest

Evolution from a genes perspective. Loved it and many a times, turned to YouTube to experience and learn more. 

5. Black swan

This is again a long book but fascinating. Read it for the longest time and still marinating on some of it idea. Cryptic language but love the way the author was playing with the reader throughout the books narrative. 
6. I built the Industrial Age Henry Ford

Started the book thinking I know the crux of the topic but found lot of new perspective. The author transforms the reader to a time when cars were just introduced. It reminds me of the digital and mobile transformation that is happening now. Loved the entire book although felt the organisation of chapters was a bit off for me.

Do you have any recommendations?

Error spawning ‘cmd.exe’ and how to solve it


Yes I know the world have moved beyond visual studio 2013, but at office we are stuck with Visual studio 8 and after working for some time, it spits the following error.


Error 4 Error spawning ‘cmd.exe’.

Then, I have to close the visual studio and restart again. This works. Although not ideal, I was happy doing this as writing the method was more important than tinkering with visual studio.

Last week I had enough and decided to google and get this sorted.. So here’s the solution from ever useful stack overflow that worked like a charm for me.


Just open Tools -> Options -> Projects and Solutions -> VC++ Directories

and add these lines :


Now back to work!!!

Historical Primer on the Algorithms, and Techniques that are shaping our world

giants of machine learningLast year in April I attended a good course of machine learning which pushed my self learning to a new level. The course also introduced the language R and I have loved dipping with machine learning since then though most of it is done in python.

We had an excellent trainer with more than 20 years of experience in the field. I loved his 101 course in statistics as the prelude to the course and the practical examples that the trainer brought up while teaching us the mechanics of perceptrons, ridge regression etc.

What the course lacked was an historical perspective on machine learning and how it all came about as we now know it.

Found this excellent video that provides that perspective.

From the first meeting in summer of 1956 to the many A.I winters followed by the eventual emergence of deep learning, the below video provides an excellent historical primer on the algorithms, and techniques that are shaping our world.
