In C++, most STL algorithms can use one function to perform their job on a collection. For example, to extract all the even numbers from a collection, we can write code like this: auto const numbers = std::vector<int>{1, 2, 3, 4, 5, 6, 7, 8, 9, 10}; auto results = std::vector<int>{}; std::copy_if(begin(numbers), end(numbers), back_inserter(results), isMultipleOf2); Assuming […]
Interrupting a sequence of operations when one of them fails is a common problem in computer programming. There are plenty of elaborate ways to code that, ranging from exceptions to monads to static exceptions. One of the techniques to stop such a sequence of operations that is not so sophisticated, but that can be found […]
This is a guest post by Vaughn Cato. Vaughn has been developing using C++ since the early 90’s and is still learning! You can find him on Twitter @vaughncato. Thanks to Ricardo Nabinger Sanchez for his review of the article. Refactoring is a technique for making improvements to the design of a code base without […]
I’ve been recently interviewed, not “interviewed” in the sense of job-interview, but “interviewed” in the sense of let’s interview this person to know about their story (which would also part of what you do in a job interview, but anyway). If you’re curious to know about my story and how I ended up doing what […]
Technical debt, legacy code… if you’re a professional software developer you must have come across those terms, and even across some code that embodies them. But as a professional software developer, you also have to interact with people that don’t know your code. And sometimes, you have to convince these people that you need to […]
Every piece of code we write is unique, or pretty much. However, there are things that are common in a lot of code, even across various codebases, and even across various languages: the physical shape that code has. Beyond the mere visual aspect of code, the shape of a piece of code can carry information […]
A few years ago Sean Parent presented his famous C++ Seasoning talk, where he recommended avoiding raw for loop and using STL algorithms instead. This made a lot of people sensitive to this topic, and encouraged us to think about how to convert the for loops in our code into more declarative constructs. Recently I encountered a […]
This is a guest post by Tobias Loew. Tobias is programming now for over 35 years and started with C++ over 20 years ago. Got a PhD in maths and work for steag developing thermodynamic simulation tools (EBSILON). He likes to spend his spare time with his wife and their bunnies and writing code like […]
Have you ever felt that the code you write in if statements doesn’t look as natural as the specification expresses them? For example, if the specification looked like this: “if any of x, y, or z is less than 100, then perform such and such action”, a common way to express this condition in C++ […]
This article is NWH, standing for Not Written Here. The concept of NWH is inspired from the NIH (Not Invented Here) syndrome which consists in refraining from using existing code from outside the company and reinventing the wheel every time. Just like it is good practice to look out for solutions developed elsewhere, we’re going […]
