I don't know about Mozart, but everything I've read about OCaml suggests that the O in OCaml is second class. I've even heard it quoted that the creator of OCaml doesn't use any of the OO features in OCaml and that most people view them as

I think you give Scala a disservice by saying there is no innovation in it. I have programmed in Perl, PHP, Python, Ruby, C/C++, Java, C#, and even a tiny bit of Scheme and Clojure, but Scala is the first language I have seen to so successf

I guess I've been causing the death of kittens for a while then. I couldn't, however, deduce from your wikipedia link or from a quick google search what the correct way of adding floating point numbers should be, though. Even the MS compile

In a perfect world, a compiler would optimize this code to be equivalent to summing in a simple loop, at least if series were a projection or had a non-strict map function. Whether scalac and the JVM can work together to do this right now o

On my 1.4ghz core 2 duo laptop, which isn't a very powerful machine, the above scala code runs in about 1 second when compiled. If I let the code run once to to let the JIT warm up and only measure the execution of the main body, it runs in

Ruby introduced me to the ideas of first class functions, closures, and higher order functions and the design patterns that can be easily implemented using them. These same patterns can be implemented in Java, albeit with a much more verbos

Check out this page: http://buildr.apache.org/quick_start.html . I will paste the most relevant text below. "No knowledge of Ruby is assumed. Buildr is designed to be a very intuitive, very easy-to-use tool. You can create buildfiles which

As I mentioned elsewhere in the thread, buildr manages dependencies just like maven, including the ability to download sources and javadocs, and also has an ant integration library that works really well. Finally, buildr supports generating

buildr combines the advantages of maven with the advantages of being built on top of rake and scales to managing multiple projects. Groovy's Grails build system and Scala's sbt also both look good to me, although I have not yet taken the ti

Vectors may be implemented very differently from mutable arrays, but it is my understanding that they allow for efficient appends and updates, not efficient prepends. I would still switch to using lists, if only because when doing performan

He's using vectors with clojure and lists with lisp. Why? It looks like he's concatenating vectors, which is O(n), with clojure, but cons'ing lists, which is O(1), with lisp. As much as I like seeing clojure's performance get critiqued, thi

I thought most of us agreed by now that ref-counting is slower than GC? http://www.idiom.com/~zilla/Computer/javaCbenchmark.html cites a paper empirically showing just that. I quote: " In a well known paper [2] several widely used program

Even in Kernel programming, exceptions are useful. If you read http://www.kernel.org/pub/linux/docs/lkml/#s15-5 , you'll see that goto's are used to reduce code duplication for error handling, which is essentially just a poor man's excepti

Neither javascript or python or fast enough to matter. Look at the alioth tests ( http://shootout.alioth.debian.org/u32q/benchmark.php?test=al... ). V8 is still 25 times slower than C. Does it really matter if you're 25 times slower than C

When you tried sandboxing python, did you look at http://wiki.python.org/moin/How%20can%20I%20run%20an%20untru... ? There's multiple sandboxing options listed there. Also, Python has SWIG, SIP, and Boost to help integrate native code. I ha

I won't be switching to javascript from python anytime soon. Javascript took about half of the bad ideas from perl and mixed in a few bad ideas of its own into a not very good language. Invoking a method on a primitive string silently fail

Sorry if I started sounding like I was making this a Java vs. Clojure approach. I wasn't. My original point is that there are no compelling reasons for me to use a language like Clojure over a language like Ruby. Clojure's biggest selling p

This link is fairly illuminating of clojure's performance: http://gnuvince.wordpress.com/2009/05/11/clojure-performance... . A guy writes some Java code, writes some clojure code, and notices that the clojure code is ridiculously slower, a

I haven't seen a compelling reason to switch to clojure either. Despite some people trying to argue to the contrary, fair benchmarks that I've seen put clojure on average at least 10 times slower than Java in CPU performance, and Java itsel

The author didn't, as far as I understand, make the code reentrant. The code still operates on mutable state outside of the scope of the call such that two calls that pass in the same inputs may produce different results. The author simply

It is fairly easy to avoid symbol soup in ruby. First, don't use global variables. I'm perfectly OK with global variables sticking out and looking ugly. Second, use the English module packaged with Ruby if you find yourself using Perl-like

I feel like people miss one of the main points of this FQA. The author repeatedly asserts that most people who think they need C++ do so because they think they need the performance it can offer. Most of these people, however, don't actuall
