An interesting discussion including Yannick Grenzinger, Romeu Moura and Daniel Gonçalves has recently happened on Twitter. Thanks mates for the respectful and enlightening exchange. It started from this: The first objection was from Yannick Grenzinger: Which, as Daniel Gonçalves noticed, resonates a lot with an older tweet from Nicole Rauch: I […]
A few weeks ago, an interesting discussion arises on twitter (in french, sorry for my foreign readers). In a nutshell, it all started from a (french) post by Arnaud Lemaire about why he hates developers contest, where he explained that this kind of behaviour is infantile. Thomas Pierrain explains why […]
Does it already happen to you that a book is so good that you can’t stop read it? I’ve experienced it a few times. For H2G2, the Lord Of the Rings or the Dark Tower for example. But for the first time it happens with an IT book: The Computer […]
Patterns of Enterprise Application Architecture is one of the many interested books written by Martin Fowler. I have a lot of respect for Martin, mainly because he’s able to constantly challenge himself and improve his craft, since several decades. Here is what I like and dislike about this book. A […]
If the hardware has followed the Moore’s law, what happened to software? We have built assembler, and compiler, and high-level language. And now we have powerful machines, and all these shiny new languages and frameworks promising productivity. So why the hell are we still providing lame software? The software crisis […]
Here is another privileged white guy who stand up to talk about diversity. Let me explain why. Google memo, Uncle Bob and the SoftwareCraftsmanship community If you didn’t follow this thread, you can have few information here. The thing to understand is that it’s a big matter. There are lots […]
If you have grasped the mathematical basics, and if you have understood what’s a monoid, you are ready to discover monads. Of course, we’ll continue to have fun with F#. There are tons of approaches trying to explain what monads are. Personally, I found out once I understood the problem […]
Let’s have some fun with F#. Through example, we will discover together what are monoids, and why they could be useful. All the following code can be found online. Function composition example with integers We now all agree about what’s function composition. We all know what are integers. So, let’s […]
You remember that Functional Programming (FP) is all about function composition? But what’s composition by the way? Let’s explain it here with a few other useful concepts for FP, and go one step further in monads understanding. Integer composition A composition of integer in mathematics is a way of writing […]
I’m so used to functions in my daily job as software programmer that I was sure to know what it is. As often I was wrong, let me tell you why. Function and relation I intuitively called a function anything in my code with an input and an output. I […]
