Ask HN: What are the biggest fads in software engineering right now?

For one, I could think of Big Data/ Hadoop. In the past one year, at least ten "coaching institutes" have sprang up in the area I live (in Bangalore) claiming to teach Hadoop and promising high paying jobs.

I went in there for a "demo session", and they are like "you can learn Hadoop and get a high paying job with absolutely no programming experience".

Anyway, these places always get some kind of gullible people.

I think this is a fad, and it will die down soon. What do you think about this ? Do you think there are any other fads like this ?
