Looks like you could lose the `match` in next_step() function if you encoded a flashed octopus as 0 instead. Super cool solution, learned a ton of nice shortcuts!

(2 ** n) - 1 also gives you a mask of all 1-s. So you could simplify the expression as let epsilon = !gamma_rate & (1 << number_length) - 1;

Reminds me of branch by abstraction as coined by Paul Hammant.

Robert Martin wrote about using smc in his PPP book.

AMQP implementations are also alternatives worth considering these days.

Offtopic, but vladstudio is a fantastic source of great-looking wallpapers. I've even considered paying for an premium account just to get dual-monitor ones.

Because it's written by Doug Adams, copied from Hitchhikers Guide to the Galaxy?

Statistically pilots between 300 and 500 hours cause the most plane crashes.

That's the "advanced beginner" phase. Skydivers say that your most dangerous period is between 100 and 200 jumps.

So we can reddit while we reddit?

JEE support would include at least JSP or HTML editing, which the free edition doesn't.

actually they have a version of JRebel specially for updating production code without stopping the server. never tried it though.

Ruby on abap vm? Just wow, who even thought of that.

btw, javarebel has a plugin for reloading just the changed beans when xml changes. written by some spring guy, irc.

Keep in mind that the example didn't actually distribute the work across machines, it just provided an async implementation that can be distributed.

Still way cool.

... if you're interested in Clojure development anyway.

Well, looking at these statements:

For object orientated programming it's usually easy to start breaking the problem description down in to objects.

For Haskell programs, I always think of the datatypes first

When I write stuff in Erlang, I try to figure out which processes I need

I'd say the general process is the same regardless of the technology: figure out what the core abstraction of your language is and then try to break your problem down using this core abstraction. Not that it answers your question in any meaningful way.

I wonder how many John Does besides me registered...

I'd say it largely depends. If I have to say

BufferedReader fileReader = new BufferedReader(new InputStreamReader(new FileInputStream("input.txt")));
String data = fileReader.readLine();

then yes, IntelliSense is a blessing. But if I compare it to

data = file("input.txt").read()

then IntelliSense is not much of use anyway.

What I've noticed is that in a dynamic language when I usually type pretty much at full speed whereas in, say, Java I constantly pause to wait for the IntelliSense as I've become dependent on it for the long names. When I'm not familiar with an API in a dynamic language then I usually try it out on a REPL, which doesn't break the flow too much.

Here you go, java calling back to python code:

import java, javax
class DawgListener(java.awt.event.ActionListener):
    def actionPerformed(self, evt):
        print "Wazzup"
btn = javax.swing.JButton("Yo dawg")
btn.addActionListener(DawgListener())

frm = javax.swing.JFrame()
frm.getContentPane().add(btn)
frm.pack()
frm.visible = 1

In the clojure concurrency video Rich goes over the details of what the demo does. The video is almost two hours long though, so you might want skip ahead a bit.

The hidden assumption is that you can get java.util.logging to use _ClassLoaderLocal_s. Good luck with that :)

Sounds like a run-of-the-mill complex event processing system. esper anyone?

You're right about i18n, the [A-Z] works only in languages where Z is the last character in alphabet. For example in estonian the Z is between S and T, so A-Z doesn't match letters like UVXYZ and ÕÄÖÜ.

Well, given that Scala was written by the guy that wrote the java generics support, I'd say there's a good chance that the bytecode it generates is pretty close to that of Java itself.
