Similar question, or related:
For "daily" jobs, perl/python/bash would be enough as my work is in bioinformatics.
I found out C/C++ maybe the "must-have" if any complicate problems like genome assembly (string searching & joining) with big data files are (10~100GB of millions of rows) normally used.
First skill is to handle big files;
Second is manipulation of data structures (suffix arrays, transformation of data format/structure) using smart algorithms.
Both need manage memory efficiently, and C/C++ seem the best choice, if not the only one as I know.
I was wondering what background are those softwares devloper? Guess they are majoring in software engineering. And how did they develop the prgoramming skilles? Or, how can I develop skills to glue the components together like the software enginner?
"Practice-practice-practice" is too vague to me. Especially I am stuck at the beginning.
