RunThis - Let your readers run snippets of code directly from your blog.

Clever idea. Pretty impressive language support and I like the way the output is presented with some useful meta information. I would love to see the team at Github integrate this into the http://gist.github.com platform.

I assume the results here are cached, right? This would obviously get very resource-intensive on even a marginally popular blog.

Cool idea.

For this to be really useful, it needs to be able to define a snippit (e.g. a function), and then let the user type his own code (e.g. an application of that function) to see the results. Otherwise, if everything is static on the page, you could just pre-calculate the results when building the page.

If it sends the code back to the server to get executed, I could see a slew of interesting security opportunities here. I wouldn't exactly allow someone with Firebug and working knowledge of C run executable code on my server.

Cool idea! Hopefully I'm misinformed about the security thing.

Does this give you anything that a pre-calculation of output during blog post upload doesn't give you?

When I tried running it everything timed out. Did it work for anyone else?
