Something I've been waiting for for a long time!
Introducing Google+ Collections, a new way to group your posts by topic

Our happiest Google+ users are those who connect with others around shared interests and passions. So we set out to give people a place to express the things they love. Today, we’re announcing Google+ Collections, a new way to group your posts by topic.

Every collection is a focused set of posts on a particular topic, providing an easy way for you to organize all the things you’re into. Each collection can be shared publicly, privately, or with a custom set of people. Once you create your first collection, your profile will display a new tab where other people can find and follow your collections.

Posts in collections you follow will appear in your Home stream, with a link to easily jump right into the collection so you can get to similar content from that author. Collections give you a great way to find more of the stuff you love from the people you follow.

Collections is available on Android and the web, and iOS is coming later. For Android users, make sure to update your Google+ app to get access to Collections.

For inspiration on interesting topics, check out our Featured Collections page here:

Create your collections today and share what you love.

I've finally written some documentation for my pretty library! Here it is: For the impatients, have a look at the bottom of the page for an interactive demo of a JSON pretty-printer.

(Library is available on pub at

See +Kevin Millikin, the README didn't lie after all, more documentation was really underway :)

Something I've been playing with: an interpreter for a multi-stage version of Dart.

Multi-stage programming is like programming with backquote, comma and eval in scheme except that variables occuring in quoted expression are statically bound, as in MetaML [1]. Code is quoted with <expr>, spliced with ~expr and run with run(expr).

Multi-stage allows for the specialization of functions. For instance, in the linked example (it's an interactive demo, you can play with it), the spow method is an annotated version of the pow method which allows for specialization of its second argument. The scube method specializes it for n = 3. You can see in the output that it evaluates to (x) => x*x*x*1, and not (x) => pow(x, 3) as the cube method (the partial application of pow to 3) does. Imagine a program where scube is used many times: it's a net win over cube!

The language of the demo is a very small, purely functional and strict subset of Dart.

Of course the whole thing is written in Dart :)

Meant to share this with this community in the first place but I mixed it up with my Dartisans circle.
Couldn't find a priority queue in Dart so I wrote It comes with two example files, extensive tests, and some dartdoc for every method. Feedback and pull requests welcome!

By the way +Seth Ladd, I tried to change your A-Star lib to use it instead of a list + linear find min. Turns out it scores slightly worse on the benchmarks, but if you increase the size of the mazes used in the benchmarks then you get some speedup (I've observed a 2x speedup on 200x200 maps or so if I remember correctly).

This evening's project: pretty-printing combinators. Consider this an alpha release for now.
