Opa: Advancing web development to the next generation. I think I mentioned this in the old blog, but what the heck - now the code is on github and under an open source license. And the entire project is not just something that has recently come out - it has 10 years of research behind it, the people really know what they are doing. The idea is cool (and has already been adopted by others as well): a language from which all layers of web applications are generated, including JavaScript, HTML, CSS, and the backend. All of this with type safety and corresponding checks and, for example, resulting security against injections and XSS attacks. And the language runs on OCaml underneath, which is also not the worst language. I should really seriously deal with this, especially since distributed installation comes along with it - and thus a far easier scalability is given than with many other approaches (the one from OPA reminds in a certain way of the one from Erlang-based systems). Oh, and web applications are then simply just a single executable - and not gigantic directory structures with thirty-nine XML files (or YAML files) to customize.
