The 0.2 release of the FreakyFreakySandbox is here. I almost had to add  
a third  
Freaky because of some thread-related haps, but they’ve all been  
sufficient  
scared and squared. Everything is now calm, like grapes on a gold  
platter.

gem install sandbox --source [code.whytheluckystiff.net](http://code.whytheluckystiff.net)

Or there’s a dist (with setup.rb inside):

[http://code.whytheluckystiff.net/dist/sandbox-0.2.tgz](http://code.whytheluckystiff.net/dist/sandbox-0.2.tgz)

You will need to patch your Ruby 1.8.5 to do this. Instructions:  
[http://code.whytheluckystiff.net/sandbox/wiki/InstallingTheSandbox](http://code.whytheluckystiff.net/sandbox/wiki/InstallingTheSandbox)

The sandbox extension lets you create new Ruby environments, either  
restricted  
or featureful. Need a safe little housing for dangerous code, with an  
explode-proof shield on it? Aha, get over here. Or, need to load a  
conflicting  
library into a safe, clean Ruby? See, look at all these reasons.

box = Sandbox.safe(:timeout =\> 10)  
answer = box.eval(unsafe\_code)

Looksee, in this release: a timer. If you can best it, I will give you  
a  
free, no-strings-attached photograph of young Hayley Mills.

The sandbox is often prefixed FreakyFreaky, as a warning to all that  
this is an  
extreme hack, very experimental – practically implausible. However, it  
turns  
out that Ruby threading kind of does this trick anyway, so it’s not  
really that  
bad. Anyway, I like the prefix and I call the shots on this one, guys.
