    I Need an App

    As a startup coach and as a freelance app developer, that’s a sentence I hear a lot. Entrepreneurs with a business idea, but not necessarily the tech know-how to make it a reality, want to know what it takes to develop a mobile application. And of course, like many things, it’s not as easy as […]

  • Couchbase and the API model

    On my last job, working mostly on our iOS app as a frontend developer, something struck me hard. So much effort went into building plumbing code, things like offline caching, pagination, connection error handling. Whenever I spend so much time on infrastructure code instead of implementing features, I’ve always started questioning the very paradigms I’m working […]

  • Android Studio and the future of Java IDE’s

    Yesterday, when they announced Android Studio during the keynote of Google I/O, my very first reaction was “Oh no! Too bad for Jetbrains! Even though they build awesome plugins for Android development, they will be taken over by Android Studio, beaten by their own platform!”. But then I saw this: And I realized that even […]

  • Payment Processing Landscape in Europe

    It is a well-known yet long-standing fact that setting up payment processing is much harder in Europe than it is in the United States for example. A major reason for that complexity comes from the fact that, contrary to the US where they have big national banks that cover the entire American market, European payment […]

  • Top 5 reasons why you should consider Groovy and Grails for your enterprise software architecture right now

    I’m so amazed when I see how so few companies are using Groovy and Grails right now, and are still using old stuff like Spring and Hibernate, that I thought I would jump in and do my share of educating. And why not give in to the fashion of top lists while I’m at it? So here it goes: if you are an enterprise software architect and you have a lot of Java in your world, you might want to read carefully what follows.

  • Why I switched back from Heroku to CloudBees

    I used to have several grails applications deployed on CloudBees. I liked the fact that they were Java all along, I liked the smooth integration between Jenkins CI and the deployment environment. I really liked the fact that you could hide an application behind a username and password during testing. I just hated their design […]

  • Grails, Vaadin and Spring Security Core

    I got kind of bored with Flex and all the complexity it introduces by forcing you to switch between ActionScript and whatever you are using for the backend (Groovy in my case). I also got bored with having to regenerate my data service stubs on each server-side change, and having to handle the asynchronous remoting. So I started to have a look at Vaadin.

  • My Case for DTO’s

    In many of my posts about Grails and Flex integration, I take for granted that I use Data Transfer Objects to transfer data between my Grails backend and my Flex frontend. Put simply, Data Transfer Object are pure data containing classes different from the domain entity classes used to store data in the backend. I take it for granted because I’m deeply convinced that it’s the best way to do things and so far, experience has never proved me wrong. But I often get this question in comments or by mail (this is for you Martijn): why bother create an entirely separate class structure and copy data from entities to DTO’s and back instead of just using entities?

  • Flex on Grails, Take 2: Part 3

    At the end of the second article in this series, we ended up with a working application but it was not really ready for the real world because it had one major flaw: the URL of the AMF endpoint was hardcoded in the client in such a way that it was impossible to change after compilation and very hard to handle several environments (dev, test, prod). The solution to that problem is to integrate dependency injection into the mix.

  • JVM Web Framework Survey, First Results

    Yesterday at Devoxx, Matt Raible did a very interesting talk on comparing JVM web frameworks. On this occasion he had the incredible courage of voicing his opinion on each of the most well-known frameworks, rating them in a matrix and the craziest part: showing this matrix to everyone. Immediately after his talk, Twitter was on […]
