Glad to see this. As a longtime Java developer I've found Scala has made coding for the JVM fun again.

Glad to see Bruce Eckel involved. It's interesting to see just how many Scala books have been cranked out in the last 6-12 months or are currently in progress.

Seems he forgot the link. Another excellent book for learning Scala is Scala for the Impatient. The first 9 chapters are free: http://horstmann.com/scala/

You'll get similar results for most benchmarks. Languages such as Ruby/Perl/Python are consistently slower than Java. There's no such thing as a perfect benchmark, but I've found the language shootout page to be a pretty accurate reflection

Figuring our how core libraries such as the collections framework work is pretty easy if you get a good book like Scala for the Impatient.

Yeah that seems to happen if you leave type aware highlighting enabled. Seems to work well with that switched off.

If it took you hours to get hello world working perhaps you should consider going back to school?

Java has been pretty fast since it used a JIT circa 1998. The main reason it got a bad rap was that it needed tens of MB of memory for basic apps. This means that folks with their Pentium I's and II's with 64MB RAM perceived Java as slow si

There isn't an IDE with a scala plugin that fully supports scala IntelliJ provides an excellent free scala plugin. What have you been using?

High school students all over the world are quite happy to write Java code like that without any issues.

Java is slow ... It scalability is a joke. I've worked as a Java contractor at a number of places and what a PERL/PHP/Python solution can get done in 5 boxes, it takes Java 30-40 boxes. This is NOT an exagerration. Hard to believe this

For a language that will "never be mainstream" it seems to be picking up steam pretty fast. We're very happy with it. Sensibly written Scala code is much easier to read than Java, and that's coming from someone who has been using Java for

Tumblr and Twitter don't strike me as a particularly conservative audience. Quite the opposite.

It seems very subjective (and somewhat arbitrary) to assign labels of "conservative" or "liberal" to languages based largely on type safety. If this random blog post is taken as the definitive source of "conservative" vs "liberal" we get th

Does anyone have any benchmark numbers for either?

yeah free version supports Java SE, with a really nice Scala plugin for download via the plugin manager.

Yeah, from the site it looks like they are running "true native applications", so probably using native UI widgets.

Citation?

The inclusion of type information for method parameters makes for some pretty nice tooling. Check out the error checking and code completion at around 30:00

Fair point. Thanks for pointing that out. > "While there are some great JVM GCs, I wouldn't walk away with the impression that the .NET folks are behind by any means. " Can the .NET GC provide deterministic real-time collection pauses?

The point my original post makes is that .NET having concurrent GC is not exactly groundbreaking. This doesn't have anything to do with the so-called expressiveness of C# relative to Ruby. >The bytecode language is not standardized, and

The world has moved on to more advanced concurrent GC implementations. Citations above.

That is seriously impressive. How many universities get the creator of a language in to teach you how to use it?
