17-08-2017

Frits van Campen

We build modular web applications in JavaScript. To achieve modularity we need to enforce a limited scope. We take a look at how we approach exposing native functionality and specifically the case of event.stopPropagation().

On type safety without generics, and the role of package design

02-06-2017

Arnout Boks

At Moxio we strongly value writing type-safe code. This can be a challenge in PHP however, especially as it lacks a feature known as ‘generics’. In this blog post I will show how (lack of) generics influences type-safe design, how parameter types and return types may change when extending a class or interface, and how we can keep our package design sound while doing so.

In this blog I will share the process of redesign the dashboard for one of our more complex applications. How we create insight through combining data, enhance insight by good visualization, create possibilities for interaction and guide the user to the right data.

Review Roulette: Everyone is a winner!

31-03-2017

Arnout Boks

In an earlier blog post I introduced our idea of Review Roulette, a process of randomized code reviews with the aim to foster learning and increase collective code ownership. I explained that we would try this idea out as an experiment for two months and evaluate afterwards. I also promised to share the results of that evaluation. In this post I will do so, and describe the steps we took to make Review Roulette work even better for us.

Understanding Exceptional Flow

15-03-2017

Maybe you recognise the following situation. You are implementing a new feature, and you know that you can use a certain method, as it already covers some of the functionality you need. You briefly look at it, and you don’t see any exception handling constructs. But can you be sure?

Everyone who writes SQL queries encounters them once in a while: those queries that just take too long. In this blog post, I will first describe the system, then show how the problem could arise and lastly, how we solved it.

Frits van Campen

Cross-origin resource sharing (or CORS) can be used to make AJAX requests to another domain. We'll look at how to set up CORS on the server in PHP, how to make the request in JavaScript and some considerations.

Detecting hidden bugs in PHP code using PHP_CodeSniffer

01-12-2016

Arnout Boks

Although PHP serves us well as a programming language, we cannot deny that some of its behavior can be very surprising, which can easily lead to hidden bugs. In this post we will look into two potential pitfalls in PHP, and how these can be detected and avoided using our open-sourced collection of sniffs for PHP_CodeSniffer.

Introducing Review Roulette

20-09-2016

Arnout Boks

At Moxio we recently started an experiment we called 'Review Roulette': a process of randomized code reviews. We believe this emphasizes code reviews as a means of bidirectional learning and helps onboarding junior developers, and thus improves upon our previous review 'policy'. In this post I would like to sketch the background behind this experiment, explain the idea of Review Roulette and present some preliminary results.

CSS transitions not being ignored when printing in Chrome

29-08-2016

Peter van Dommelen

Currently there is an issue in Chrome relating to how print stylesheets are applied when printing. Other browsers do not have the same behaviour. The problem like how we came across it is also described in the Chromium bugtracker where it has been marked as fixed and will be resolved in a future Chrome version. I will attempt to show how the bug behaves and why the issue is not yet entirely resolved in some cases.
