“Programmer migration patterns” is an interesting attempt to identify where programmers start and how move from one programming language to another. This is not precise science, obviously. But I have to say that I mostly agree with the findings.
The first language that I learned (back in school) was BASIC, which then gave me some legs with Visual Basic later in college. Also in college, I’ve learned assembler, C, and Pascal, which guided me to some amateur and professional development with Delphi.
Soon after that I discovered Linux, which meant shell scripting. I played with awk, but I didn’t have to dive deep, as Perl was already available. Perl was probably my first true programming language, which I learned outside of school and college, and which I have been using for years to build all kinds of things. I still love Perl dearly, but the last few years I have been mostly using PHP, with some occasional Python.
Here’s a good collection of cheatsheets for anyone involved with Big Data and machine learning. Whether you are already well versed in the subject, or just starting, I’m sure you’ll find something useful.
And while we are on the subject of machine learning, check out this repository for examples in Python, theory and math explanations behind many algorithms involved.
PHP vs Python vs Ruby: Detailed Comparison compares the three popular languages in a variety of categories, such as total market share, large website deployments, usability, learning curve, popularity, performance, etc. It’s a nice overview if you are about to pick one of these languages for the future projects, or if you are (like me) have been stuck with one of them for a long time, and haven’t really kept an eye on what’s going on in the rest of the world.
O’Reilly is giving away some programming ebooks for free. Not the greatest of selections, but might still come handy, as subjects vary from Java and Python to micro-services and software architecture. The books are available in ePub, Mobi, and PDF, but you’ll need to register / login to download them.
