Reader’s digest April month issue made a cover story on why multi tasking is inefficient and risky. I liked the way they presented their views, one example is to write A to Z and 1 to 26 in a paper; alphabets all at one time and numerals the second time. I clocked 20 seconds to do both tasks one by one. Next was to write A and then 1, B and then 2 and go on. This took me more than 30 seconds and I was not able to write as neat as I wrote in the previous attempt. This shows two simple tasks are inefficient when we switch contexts.

They then gave some examples people trying to multi-task and getting into car accidents or falling off the stairs etc (Mostly cell phone distractions). I have observed people who multi-task a lot to be more absent minded. My inclination is also to concentrate on one task at a time and for years I have been reading emails at the start of the day, lunch and end of day & switch off instant messengers at work. I like to compare working on a task to falling asleep, on an average it takes about an undisturbed 13 minutes for an individual to fall asleep; any disturbance before that is going to delay the onset of sleep. I can assume that a task that requires concentration at work will also need that undisturbed time (7 to 13 minutes) to settle into the mode and get going where the instincts take over the conscience (That is the point where I have been the most efficient).

Sadly the work places now are getting livelier and noisier, I mean it literally. Inviduals have begun to dive into multiple streams of work and often have to switch contexts. This leads to inefficiency and puts some individuals into a vicious cycle of coffee, long hours and lack of sleep until they go on vacations. If the environment is also micro management friendly then that adds more fuel to the vicious cycle of inefficiencies.

In my workplace I have observed people concentrate the most when they play a team game like AOE, where the only conversations are brief messages and status exchanges as the goal is to keep moving until you win. The work place core hours should be inclined that way to cut out not only literal noise but also disturbances which will make us switch contexts too often. Some rigidity in the schedule is required as it helps to get people into a rhythm, the schedule should also keep in mind the team’s composition to accommodate different individuals as they peak at different times during the day. Try getting your team and members work on a mutually agreed schedule of no meeting times and feel the difference it makes to every individual.

Like the memo function in programming our brain tends to get conditioned over time to provide immediate output to inputs. A good example is learning to drive. Earlier one is too conscious about the steering, vehicle’s response to throttle and brakes; over time people forget the fact that they are driving and indulge in nice music or a conversation as driving becomes automatic to them without having to think.

Doing the same thing again and again makes the task etched so well into our brain. This is true for any given task whether it is good in nature or bad, the subconscious does not differentiate and it keeps trying to make you efficient. Therefore it is important for us to make sure our exposure from friends. books, tv and workplace is generally positive and our attitude is generally positive.

Over the years I had a chance to work under different kinds of people and subsconsiously they have shaped me to what I am today. I have observed often that the bad habits gets passed from the peers than the good ones as they have an illusion of short term gains. The bad habits gets passed on mostly in the form of gossip and getting the bad views and thoughts over and again is so powerful that it can create illusions that can last a life time as the real data wont be verified.

For example, the resistance to change was so powerful that it took me about 6-7 months for me avoid the words ‘actually’ and ‘basically’ when I talk. After I decided to get rid of them, I kept a conscious watch of when I use those two words. For the first few weeks I used to say those words and kick myself because I keep repeating the mistake. About a month later I was successful in controlling those and forgot tracking that after the first couple of months. After 6 months or so I noticed that I had got rid of it, unlearning was far more tougher and time consuming process than learning.

The difficulty to unlearn is due to the brain’s inclination in making the input/output super responsive that most of them would be cached. The instincts are the ones which mostly controls and the conscience is a mere supervisor. We should make sure to check that we dont form any habit that make us look incompetent and will make us pay a lot to unlearn.

Not only we should avoid negative influence, we should also keep learning and try to increase our skills in depth and breadth, as over the course of time the brain will make the learning process more efficient and we will get better and quicker in picking up new things.

Practice makes a man perfect. Keep learning every day.

I was very curious whether the way you think and act is directly related to the language you speak. I did some Bing search and stumbled on few blogs which mentioned about the lack of left or right in a language called Kuuk Thaayorre. They have to refer everything in terms of cardinal/ordinal directions. There were interesting examples in  Scientific American. I was impressed by the fact that in the language Kuuk Thaayorre it is impossible for someone to refer something without knowing the direction. This forces them to be oriented always and that is because of the language they speak. It even affects the way people think about time and space, the English say the future is ahead and Chinese say the future is down there or the English say it is a long day and the Chinese say it was a big day. So a person’s thinking is influenced by the language s/he speaks.

Will these be applicable to programming languages? Is a programmer’s thinking influenced by the first language s/he learns? It seems it could be true. I observe that Java as a language did not change much (faster) but polyglot programmers have contributed to bring in efficiency and elegance which they learnt while using other languages. An example which I also stated in my older post (Don’t make me think) is LambdaJ, which helps in writing expressive code in Java when working with collections while not worrying about writing obvious for-loops. Frameworks like Roo help us to avoid mundane Java boilerplating and concentrate only on functionality. There should be many more out there which has helped Java developers but influenced by the features of other languages and frameworks.

A programming language has an option to keep growing through upgrades unlike the spoken languages. I am not sure why a spoken language need to be restricted from acquiring parts from other languages. I am the one who missed asking the question “How manyeth candy are you having?” when I started learning English. It took me a while to understand how to ask similar questions when I had to translate from Tamil to English.

Which developer thinks better? Java or Ruby or C#…..?
