Elegance as a luxury

I am fan of Daniel Lemire, Professor LICEF Research Center, TELUQ Université du Québec. Love his blog. 

Here’s his twitter bio 

Autodidact with a Ph.D. who loves two of these three things: computer science, programming and sex on the beach.

In this recent post titled Elegance as a luxury, loved the following points about working on problems, be it software, mathematical or life.

I go slowly. Instead of rushing at the end, I try to make sure I really understand the problem. I try to see its natural components. I divide up the problems in small, manageable parts (that fit in my short-term memory).This is where my students most often go wrong. They are trying to go too fast. To try to teach them to go more slowly, I often simply ask them questions about the problem.

As much as possible, I work locally. That is, I work on parts of the problem that only require a few facts. I only move to another part of the problem once I am done with the current part.

When I was younger, I would eagerly jump from one part of the problem to another, hoping for a breakthrough. Unconsciously, I was hoping for a flash of insight. I took me years to understand that insights are more likely to come if you focus on a narrow issue.

I spend a lot of time contemplating alternatives. When I was younger, I would latch on the first credible approach I could think of. Why solve the problem in two different ways when only one way will do? I have since learned that comparing different approaches, and understanding why one is better than other, is often how you derive the most important insights.

I spend almost as much time checking my answers than deriving them. I have since learned that even “obvious” facts should be triple checked. I cannot recall how many times I got “stuck” on a problem because of a faulty assumption, or faulty derivation.

Of all the points, I need the most improvement on the last. Don’t forget to read the whole text here


Two popular theories of making change

From: Chris Guillebeau

There are two popular theories of change-making:

#1. Make small and incremental (but regular) changes. Mix it up.

#2. Do it all at once. Quit smoking immediately. Take cold showers. Enter boot camp for the soul—whatever you need to do, don’t wait.

For me it’s the combination of these two with strong inclination towards the number 1.

What’s your take on change-making?

A black swans event – Recommendation for AeSI Graduates

AeSI Graduates received this glowing recommendation from Shri PS Krishnan, Distinguished Scientist & Director ADE.

Have a look!!.

AESI graduates recommendation

The text for your reference.




I am writing this letter for the high possible recommendation for the graduates of the Aeronautical Society of India. I have seen many of the AeSI Grads working at various positions under many UAV programs at Aeronautical Development Establishment for couple of decades. I found them very sincere and diligent.

They have shown commitment for work and have impressed me and my establishment with their extraordinary understanding of the engineering fundamentals. They have contributed well with the scientists community in the lab and outside, taken opportunities to discover more about their fields of work. They have independently taken initiative of refining the methods of simulation rather than just concentrating on the results. They have also proven themselves to be adoptable and efficient manager of the resources. As an illustration of their calibre, those scientist of this stream selected in DRDO have risen to the positions even up to the Director of the labs and retired as Scientist G’s as a minimum.

As per my impression of them, they would be an asset for any organisation they are a part of and i truly believe that they will always excel in their career.

I am an AESI graduate. So was not able to resist posting it here and it does not happen everyday 🙂 It one of those black swan events !!
