Devoxx 2012 - Day 3

-- the last evening was a little hard on me, shall we say. I begin the day at noon, which suits me just fine -- Securing the client-side by Mike West If you want the largest possible audience, chances are you’ll use HTML, JavaScript and CSS. Native hasn’t (yet) the same traction as those traditional technologies. Business logic is slowly moving from those big backends toward browsers. A prerequisite to anything is to send data securely, using HTTPS. There’s no reason today

Scala cheatsheet part 1 - collections

As a follow-up of point 4 of my previous article, here’s a first little cheatsheet on the Scala collections API. As in Java, knowing API is a big step in creating code that is more relevant, productive and maintainable. Collections play such an important part in Scala that knowing the collections API is a big step toward better Scala knowledge.

My view on Coursera's Scala courses

I’ve spent my last 7 weeks trying to follow Martin Odersky’s Scala courses on the Coursera platform. In doing so, my intent was to widen my approach on Functional Programming in general, and Scala in particular. This article sums up my personal thoughts about this experience. Time, time and time First, the courses are quite time-consuming! The course card advises for 5 to 7 hours of personal work a week and that’s the least. Developers familiar with Scala will probably tak

The problem lies not in the technology

Let’s face it, I’m a technologist: I will gladly debate with you for hours on the merits of Java vs Scala, SQL vs NoSQL, Google vs Apple or what have you. But in fact, none of this matters. Statistics show that more than half of software projects are failures; I’ve been doing software projects in various positions for more than 10 years and root cause for failures was never the technology.

PowerMock, features and use-cases

Even if you don’t like it, your job sometimes requires you to maintain legacy applications. It happened to me (fortunately rarely), and the first thing I look for before writing as much as a single character in a legacy codebase is a unit testing harness. Most of the time, I tend to focus on the code coverage of the part of the application I need to change, and try to improve it as much as possible, even in the total lack of unit tests.

Use local resources when validating XML

Depending of you enterprise security policy, some - if not most of your middleware servers have no access to Internet. It’s even worse when your development infrastructure is isolated from the Internet (such as banks or security companies). In this case, validating your XML against schemas becomes a real nightmare. Of course, you could set the XML schema location to a location on your hard drive. But about about your co-workers then? They would have to have the schema in exactly the same

Why I enrolled in an online Scala course

When I heard that the Coursera online platform offered free Scala courses, I jumped at the opportunity. Here are some reasons why: Over the years, I’ve been slowly convinced that whatever the language you program in your professional life, learning new languages is an asset as it change the way you design your code. For example, the excellent LambdaJ library gave me an excellent overview of how functional programming can be leveraged to ease manipulation of collections in Java.Despite my
