One of the more popular sites of this nature is rosettacode.org, which in their own words, "is a programming chrestomathy site. The idea is to present solutions to the same task in as many different languages as possible, to demonstrate how languages are similar and different, and to aid a person with a grounding in one approach to a problem in learning another."<p>For example: <a href="http://rosettacode.org/wiki/Hello_World" rel="nofollow">http://rosettacode.org/wiki/Hello_World</a><p>Plus, I enjoyed learning the word "chrestomathy", which "from the Greek words khrestos, useful, and mathein, to know, is a collection of choice literary passages, used especially as an aid in learning a subject."

The intention behind "Hello, world!" was to show the steps you need to run your code. In C's case: compiling it.<p>These examples just show some silly code, without any further information.<p>It would be really interesting to see how some languages deploy.
Rosetta Code has Hello World in only 245 programming languages (but a huge corpus of other examples in various languages).

A bit off-topic, but the site locks up Chrome on Snow Leopard and causes one my cores to peak, and I'm forced to eventually kill the tab. Firefox has no problems. Any ideas why that might be?<p>Otherwise, a fun read-through.
