What Internet technologies were used to make Del.icio.us? Digg?

Question

I'm pretty sure Python and Lighttpd is involved somehow...

Some answerers have responded this question to reply that it doesn't matter which web technology one uses, because all of them are equivalent in power -- ie, there is nothing one can do that another couldn't.

While this is literally true, it is also vacuously true. If one wanted, one could implement a web server in assembly; then write more assembly to serve web pages, manage state, and one could even write a custom assembly database. It is vacuously true that the simplest computer language has power.

The root of my question was not asking about which languages have the "power" to implement Digg, Del.icio.us.

The properties that I am interested in are:
-Efficiency of development
-Security
-Extensibility
-Interaction w/ other systems

ASP and Java have a distinct advantage when interacting with existing enterprise frameworks, RPC, XML, etc. PHP is only catching up in that area.

All the technologies are different. I am asking which techs Internet leading websites have chosen.

It's not really relevant. Within the scope of "internet technologies" to which you are referring, namely server-side coding of some sort, and the servers that run them, all flavors are pretty much the same. They have the same capabilities and the same power - it's pretty much a choice of server platform and personal language preference as to which technology to use. Whether you choose Perl or ASP.NET or PHP or Java or any other technology, there won't be things one can do that the other simply can't. IIS, Apache, etc. all do the same thing.

I think Digg looks kind of like Ruby on Rails, but it very well may be something else. Lightttpd is certainly a possibility.
