I am going to have a look at what William Byrd presented as The most beautiful program ever written.
Beauty here refers to computer programs, specifically about Lisp. There might be errors as this is something I wrote to make sense of that interpreter, proceed at your own risk.
Thanks a lot to Carl J. Factora for the help.

I released a library based on this spike. You you can find it here: https://github.com/vsavkin/hammock.
Every client-side applications has to talk to REST APIs. At the moment AngularDart does not provide any high-level abstractions to help you do that. You can send http requests, but that's it.
This post is about a spike I did a few days ago to explore possible ways of building such a library. It also shows that you can do quite a bit in just one hundred lines of Dart.

The following shows what to watch out for when making Angular Dart applications. For more information about Angular Dart, see angulardart.org.
I'm starting to work on a new pub command. I've got two goals for it.
The first is that it can be used to install a package into your system cache. For example, maybe you're about to go off the grid and you want to make sure you have a bunch of stuff cached locally before you fall off the Internet. pub get does this implicitly, of course, but you may not have any packages that depend on the stuff you're downloading. You just want to pull it down.
Our specific use case is that we are starting to run tests of packages. Since hitting the network can fail, we'd like to do that separately from running pub get so that we can handle the failure more gracefully.
The idea is you could do:
This is an ad-hoc Java-to-Dart translator originally written on two (admittedly long) evenings.
See http://sma.github.io/stuff/java2dartweb/java2dartweb.html for a demo.
Note: It doesn't support the complete Java grammar specification and cannot translate everything. It only translates syntax and does not attempt to translate Java library classes and methods to Dart equivalents (with the exception of String.charAt and StringBuffer.append). You will have to make changes to the resulting Dart code. It does not support anonymous inner classes.
However, I was able to successfully convert a 7000+ line command line application with only minimal fixes in 30 minutes.
