Buzzwords horrify technical guys

Sometimes, you hear a guy who talks about something that he doesn’t understand at all, but… he uses the right buzzwords and so, he is listened carefuly: Web2.0, OpenSource, Agile, Cloud Computing, SaaS… How many times have you met someone who says he’s agile but his methodologies didn’t change from the previous ones (and he [...]

Java Collections Cheatsheet – v2

Hello,

When do we reach the expert stage?

In a previous post, I discussed about the Dunning-Kruger effect. As a brief summary, it means: “people reach erroneous conclusions and make unfortunate choices, but their incompetence robs them of the metacognitive ability to realize it”. When you are aware of this result, you just ask yourself whether it’s normal to be confident in a [...]

Evolving the Java language: generics were hard to implement

Are you a competent developer?

Have you heard about the Dunning-Kruger effect? The definition of Wikipedia is:
The Dunning-Kruger effect is an example of cognitive bias in which “people reach erroneous conclusions and make unfortunate choices, but their incompetence robs them of the metacognitive ability to realize it”. They therefore suffer an illusory superiority, rating their own ability as above average. [...]

You HAVE to hire technical talents! But how?

The lack of technical interview
For the last six months, I have made interviews to hire new persons (trainees or programmers) for short-term assignments. What I realize is that it is hard to say: “Ok, now, you have to pass a technical test”. The candidate may think that I don’t trust him. I know that it [...]
