In YAML, you can use the pseudo key/value-pair <<: *ref to merge the mapping referenced by ref into the current mapping.

It would be nice to have a similar concept for the sequence type that performed "splicing".

For example, if we chose ~@ to represent this pseudo-type (arbitrarily; I chose this only because the ~@ does something similar in Clojure macros):

foo: &foo
- 1

Where TDD Fails

I've just gotten back from the awesome mloc.js conference. There was a talk about compiling C# to JavaScript and one of the benefits explained was static types. Someone from the audience asked, who needs types when you do Test Driven Development?

I tried to address the question in my talk on Roy but I talked to some developers afterwards and they thought that TDD

Building the Armory Bitcoin client for the Raspberry Pi

This is how I got Armory (etotheipi/BitcoinArmory; http://bitcoinarmory.com/) cross-compiled for the Raspberry Pi.

This is a great way to keep an air-gapped offline wallet for only $30 dollars for the RPi (that you can also use for other things; experiment, it's awesome) and $7 for a Class 10 4GB SD card, really easy to keep in a safe and secret place.
