[Infoplatter – Learning notes on Programming and Bioinformatics

Bioinformatician's Pocket Reference !!

Posted on

It is amusing how the brain of bioinformaticians work! Learning a new programming language for days feels so much of fun that making 5-minute discussion with neighbors (unless under special circumstances!) in our own mother-tongue. Today every bioinformatician keeps more than few languages and core IT toolkits on their plate. It has become mandatory to be able to mold different code snippets to build our own custom workflows, and thus keeping syntax at our fingertips has become essential.Although Google is the best way to get syntax problem solved, it is not a bad idea to keep reference sheets is our smartphones or stick out some printed sheets on the back of your door, in the old fashion way!!
