Java Posse Podcast #314 all about Scala

Once again, plenty of interesting things, this time all about Scala (not about Java)

During the podcast several people said that it was a very bad idea to try to learn Scala using Lift as a training material because it is way too functional for a beginner (in the functional programming acception of the term)

• IntentService : use for non blocking operations that must not be interrupted outside of the UI Thread

Checked exceptions : really, the debat is not over

Whao, I knew that it was not over, but I did not suspect how much.

And even though I disagree with the conclusion of his article, we can be thankful to Elliotte Rusty Harold for having provided us with a thorough thread of discussion about checked vs unchecked exception.

(By the way, did I mentioned that I did not like checked exceptions ?)
