Spring

Because I get enormously challenged by it.

And I used to deliver courses back in the day for Spring Source in London.

And when I was delivering those courses, they're four-day courses.

and you've got a lot of modules and you've got a lot of exercises, all of it great content, really first-class training.

Which one? When it was cool.

Eventually it's called Eclipse Source, but we had our, back in the day, remember you're like Spring Source? Spring Source.

It was very fun.

So it was Eclipse based.
