If that's your idea of a "mild" one what would you regard as religiously offensive?

I think I could write a scalable Twitter using mostly low-paid workers who manually write down the tweets and deliver them in person. It's just a matter of hiring enough workers now that I've designed this scalable distributed system.

The LuaJIT performance is pretty impressive for a dynamically typed language, but it's hard to deny the fact that mainstream dynamically typed languages our outperformed by their static counterparts.

Relative to other tools we've used, Ruby has caused a disproportionate number of problems.

With enough hardware you can make virtually anything scale, for a price...

Statically vs dynamically typed peformance difference is clear for virtually any static or dynamic language you care to name, it has nothing to do with the jvm being "tuned" for a language: http://shootout.alioth.debian.org/

> No technology stack is perfect, but I've yet to meet a stack that was pure evil. As someone who has seen Ruby cause major problems I'd have to say it's not too far off "pure evil"

First thing I noticed when I saw the pic. Biggest obvious difference is the twin engines.

It doesn't necessarily hold. You can write a system which handles huge volumes of traffic simply by scaling horizontally with N servers. For some languages N is just a lot larger. Unless your startup has unlimited hardware resources like Go

> The less Java, the better. That's a pretty broad generalization. As Java+Scala programmer I personally seldom use, see or write Java applets. Advocating against the use of Java in general is just silly however. Java (+other JVM langua

Neal Gafter, another influential Java stalwart, has been a fan of Scala for quite a while: "Will Scala be the next great language? Only time will tell. Martin Odersky and his team certainly have the taste and skill for the job. One thing is

In truth pretty much every language's GC is worse than the JVM's.

>It was founded as a Play framework derivative, if you're familiar with that (I wasn't). Play is a web framework for Scala and Java: http://playframework.org/ We've been very happy with it.

So how would you propose measuring "contributing to the success of the adopters" ? It seems that there is no way to either prove or disprove the statement hence any statement about the "success" of a language could be claimed as valid/true.

Closures were not added to JDK 7, they will be added to JDK8 next year. Generics are definitely the biggest change, but not so much autoboxing (something that makes little difference to 99.9% of code). The annotations Java devs use the most

Java inner classes haven't changed since the late 90's. There have been new features added to java over the last 12 years, but it still feels like the language I've used since the late 90's. http://en.wikipedia.org/wiki/Java_version_histor

Your comments about Spring (not really lightweight) and Play (lightweight) are spot on.
