Python, Rust and C++ all support procedural and functional programming style. Turns out in the native languages, the compiler can optimize the functional stuff and yield similar or even better performance. In Python, however, the functional programming style makes it even slower. ...
While learning Rust, I ported my prime number generator from Python to both C++ and Rust. It is curious to see how the different languages allow different ways of writing it and also looking into the performance of it. ...
Viele der heute gängigen Programmiersprachen folgen dem objektorientierten Paradigma. In Anleitungen wurde das früher häufiger als »Nachrichten senden« erklärt, und mich hat das mehr verwirrt als es geholfen hätte. ...
In academic software development I have seen one software suite which was known to be hard to compile. I was tasked to do try it, and ended up writing a 1200 line Bash script which took care of all the edge cases. ...
Python doesn’t have variables. It sounds mind-boggling, as one seems to use them all along. But really, that is not how it works with Python. This will really confuse people with a background in C or C++. If we do int n in C++, and write n = 1, n += 1 or the like, the address &n will never change. The value changes. ...
One of the danger of C-style arrays is that their length is not attached to the pointer that points to their beginning. This means that there are lots of unsafe library functions that might write beyond the allocated space. ...
I usually program C++ with Vim. Here is a list of handy plug-ins and auxiliary tools that I use. ...
There is a rather simple problem that sometimes is asked in job interviews: ...
The numerical software that I work with is written as command line tools. As such, they get their parameters from command line arguments and/or parameter files. Their output is written to files as well. Since one can redirect standard output into a text file, we will only consider files here. ...
The other day I saw some code C which I thought to be clearly wrong: ...
