Disclaimer: I'm a developper, and, as such, I'm lazy. So please don't expect this blog to be updated very often. Moreover, most of the time I don't really know what I'm talking about (it's not like software development is my job or something), so don't expect to find very useful stuff here either. Basically it's just some sort of semi public notepad with a few problems / things I encountered. Oh, and I'm French, so my english wont be any good... That said, nice reading!

Part 1 Part 2 I particularly like this extract from part 1 : If you are familiar with Spring IoC, CDI is likely to feel more type-safe, futuristic and annotation-driven. Seam [...]

Recently I have been working on a internal component providing features similar to a rule engine. This component is embedded into live applications and as its behaviour can be tricky and time consuming, we had to provide a way to monitor method calls to this inner component. We used the JETM library to monitor method [...]

Recently I realized that Lightroom (Adobe image organizer for photographers) did not allow to display easily which focal lengths were mostly used and which ones are not (a focal length is the equivalent to a zoom factor, in a nutshell). It did not really annoy me but a coworker said to me “it would not [...]

I was recently asked the question of what tool to use in order to compare two xml files. I had no good answer to give… I mainly use notepad++ to deal with xml files. And what I do is only browsing them looking for a particular tag, searching them and so on. I don’t need [...]
