What are the cities/areas in Europe which offer good opportunities to work as a software developer/engineer?
In northern Italy, for example, I would say Milan is the city with most job openings, and most of them are, I think, web related and for consulting firms.
I think there are areas (for example the area near Cambridge?) where there are more jobs opening than average, sometimes in a niche field (such as financial applications).
Dublin used to be a very good city for example (I don't know if it still is). There are Google, AOL and other big companies that do some of their development there.
Is there a Silicon Valley clone somewhere in Europe?
Regardless of the language spoken.
