webapps

WorskWithU: "One of Ubuntu's most useful but rarely discussed features is one-click installation of a variety of popular webapps via Mozilla's Prism.

Here's a look at what Prism can do in Ubuntu, with some thoughts on why Canonical should work harder to push features like this."

Heroku is a Ruby webapp hosting service that we first mentioned about two years ago.

It started off as an online IDE of sorts, but is now a complete cloud platform for running Ruby webapps.

If you've worked with Web apps using Ruby, you might know of Rack, an interface that sits between Ruby applications and HTTP-speaking Web servers.

All of the major Ruby frameworks and server setups use it now, including Rails. Middleware (in Rack) is code that manipulates data going back and forth between your Ruby apps and the HTTP server.
