Refactoring taken too far

I came across a tweet today about refactoring badly written code. I’m always interested in that, so I saw a few fellow devs had taken some badly written code and then applied refactoring to it, following good software design principles. It all started with this article on CodeProject from April last year: The author […]

Git as a NoSql database

Git’s man-pages state that it’s a stupid content tracker. It’s probably the most used version control system in the world. Which is very strange, since it doesn’t describe itself as being a source control system. And in fact, you can use git to track any type of content. You can create a Git NoSQL database […]

Open source software on company time

Most developers love open source software, and often we come across a piece of software that we’re writing and think “it would be great if that already existed as an open source package”, but then, it doesn’t. Since we’re writing software for a company, the natural tendency is then to implement it in-house. The thing […]

Avoiding code ownership

Creating development silos, is a practice I have seen in many different teams. What I’m talking about is having developers specialize in parts of the domain, i.e. one developer handles all the code related to invoicing, another one does everything around order management, etc. It’s a natural tendency to select the same programmer for the […]

Database migrations made simple

I make no secret of the fact that I don’t like ORM’s. One part of why I don’t like them is the way they handle database migrations. To successfully create and execute database migrations, you often need to know quite a bit about the framework. I don’t like having to know things which can be […]

Writing custom EsLint rules

In statically compiled languages, we usually lean on the compiler to catch out common errors (or plain stupidities). In dynamic languages we don’t have this luxury. While you could argue over whether this is a good or a bad thing, it’s certainly true that a good static analysis tool can help you quite a bit […]

Iterators and Generators in Javascript

Last week I wrote about the yield return statement in c# and how it allows for deferred execution. In that post I explained how it powers LINQ and explained some non-obvious behaviors. In this week’s post I want to do the same thing but for Javascript. ES6 (ES2015) is becoming more and more mainstream, but […]

Yield return in C#

The yield return statement is probably one of the most unknown features of C#. In this post I want to explain what it does and what its applications are. Even if most developers have heard of yield return it’s often misunderstood. Let’s start with an easy example: IEnumerable<int> GetNumbers() { yield return 1; yield return […]

Impressions as a rookie Microsoft MVP

Last week I attended my first Open MVP day since I got the Microsoft MVP award. It was a great experience and I wanted to share what I learned and shout out to the great professionals I met there. For me, it’s an honor to be part of this community. Not only does it feel […]

Javascript sandbox pattern

A few years ago I wrote a post about Javascript namespaces and modules. In that post I discussed a pattern for isolating your code from outside code. I also promised to write up another pattern, the javascript sandbox pattern. I never did though. Lately I received a few emails about this and decided to write […]
