Manipulating files and programs using Unix shell file programs can often be a bit of a pain, even for seasoned programmers. This can be due to how infrequently you use them, or because you are often moving between OS/X, Windows and Linux, and their subtle differences can often trip you up.
I used to be fairly proficient at them, but nowadays find I use them so rarely that I often have to revise what I used to know, even to achieve the most basic tasks. For many coders, the Unix shell programming language has become like an obscure language you only brush up on when you need to speak to a distant relative at Christmas time.
Fortunately, if you know and love Python, most of what you need to do with the Unix shell for filename searching, for-loops and file permissions can easily be done with iPython, without having to spend hours revising what you first learnt to do in Unix shell years ago.

This longer post will show you some of the coding skills you’ll need for turning your existing Python code into the Python-C hybrid we call Cython. In doing so, we’ll be digging into some C static data types, to see how much faster Python code will run, and restructuring some Python code along the way for maximum speed.
With Cython, all the benefits of Python are still yours – easily readable code, fast development cycles, powerful high level commands, maintainability, a suite of web development frameworks, a huge standard library for data science, machine learning, imaging, databases and security, plus easy manipulation of files, documents and strings. You should still use Python for all these things – these are what Python does best. But you should also consider combining them with Cython to speed up the computationally intensive Python functions that needs to be fast. Continue reading “From Python To Cython”
Alas, dear Windows, it was not to be. I’m afraid I’ve been seeing other platforms. Specifically, I’ve been spending time with OS/X behind your back. It was just too painful to be with you. All those arguments, the shouting, the hair-pulling, the throwing things across the room.
Sure, you’re a lot less volatile than you used to be. And you don’t do the tearful breakdown thing any more. Yes, I know I can do almost anything with you that I can with OS/X, but everything just takes longer. OK, you want me to be honest? Fine. I find you excruciatingly frustrating to be with. Why is it always ME navigating around YOUR moods? I mean, why is it that after 25 years, everything with you is STILL a workaround?

After using Spyder for a couple of years, I recently changed my Python IDE from Spyder to PyCharm Community Edition (CE). And since I’ve now used both, I thought I’d share my impressions of each with you.
