The Artistic Way of Programming

12 years back, when I started my formal classes in computer science, the first thing I learnt was “data” means “information”. A few days after that, we started conventional programming, where code and data were treated separately. For example, only data can be passed as the functional arguments. It was difficult for me to digest that “code, which is also information, is not treated as data”. I strongly felt that this will increase complexity of softwares in the long run.

A system does three things – read, transform (processing data), write. In other words – the mathematics (the transform part), and the effect of that in real life (the read/write part). The data transformation is indeed a mathematical concept, and with the help of read and write we make the mathematics (the transform part) useful to the real world. Bringing the “transform” part fully inside mathematical domain has its own benefit of using mathematics without fear (possible errors) for the analysis of the system, making the system more tractable mathematically. The catch is to treat both the elements of transformations, data and functions, equally.

Initially, code used to be bigger than the data, so sending data over the wire was feasible. But with time, data becoming huge, sending code to systems over the wire becomes the need, resting the data on the systems intact. With big data, the need of the hour is to treat the code as data, so that the code can be taken as argument to another meta function on a system having huge data which expects an algorithm for transformations.

Roughly speaking, codes are algorithms, algorithms are mathematical functions, functions are in turn actually look-up tables, i.e. data. Hence with this principle, all codes or functions are data.This is exactly the cornerstone of the functional paradigm. The functional programming is programming with functions, they treat functions and data likewise. Another principle I love, to control complexity, rules should not be complex itself.

Thumb rules rewritten for the functional paradigm:

Read-write and transformations(algorithms) should be separate.
Use immutable variables. Discourage use of reassignment statements.
Discourage side-effects (input/output or changing any variable in-place), every function should ONLY return its expected result.
Use referentially transparent functions (sometimes it is called pure functions) with no side effects, i.e. if x = y, f(x) and f(y) should be same forever.
Unit testing is a must for each function.
One of the main design patterns should be followed is to use expressions instead of instructions, i.e. it should be declarative in nature. Discourage use of loops like for/while – use recursive statements as shown above to calculate sum. Tell computers what needs to be done, not how to do it – it reduces error, especially edge cases.
With the need to control the complexity of the system and the advance design, the design pattern for the functional composition can be made to follow some basic algebraic structures, which in turn becomes more robust.

Things To Do When Waiting For Exam Results

After your exams, you binge on caffeine, spend sleepless nights and bear a lot of stress. Well, it happens, especially when the result day is close. At times, the stress you have after exams is far intense than the stress you have during exams. There is no doubt that coping with this stress is difficult, but the tips below can help you keep the anxiety at arm’s length.

Move on

No matter what you do, you can’t go back in time to make changes. What is done is done. There is no use of comparing the answers. As a matter fact, doing so will do nothing except adding to your level of anxiety. So, take your time and move on.

Stay away from online forums

After your exams, stay away from online forums until the result announcement day. Although these forums are great places to spend time on, you shouldn’t go there just to see what others have to say about their performance in the exams. Reading the remarks of others about the exams on these online platforms may intensify your stress. Don’t sit idle

What you need to do is keep yourself busy. In other words, if you keep yourself occupied, your mind won’t pay attention to the result day. For instance, you can get a job or join a gym to keep yourself occupied. You can also start a hobby, such as gardening or photography.

Talk to a Friend

Spend time with your close friend and share your worries with them. Keeping it to yourself will only increase your depression. What you need to do is let your worries come out gradually at a certain pace rather than growing it inside you.

Write your worries on paper

In your free time, write you worries down on a piece of paper and then burn it down. While it seems odd, this technique will work wonders and you will feel better.

Sleep Well

Sleeping well is necessary if you want to stay fit both mentally and physically. It will also improve your quality of life. Ideally, you may want to get at least 8 hours of sleep in 24 hours.

Don’t drink

Alcohol can’t help you to stay happy. Instead, you should eat something healthy. You can drink milk or fruit juice, for instance. Be positive

Why should you be optimistic? Well, the biggest benefit of being positive is that it will help you lower your stress level. And this will help you deal with the stress on the result day. The least you can do is smile at others whenever you meet them. According to scientists, when you smile, you release a chemical known as endorphine. The stress hormone called Cortisol is also reduced. Therefore, you can get rid of stress by smiling.

In short, you will find these tips helpful. Keep in mind that stress will have a bad impact on your health. To stay in good shape, what you need to do is keep yourself busy, eat healthy and smile at others.
