Kite building and flying. It involves a bit of engineering and a nice reason to get away from the computer screen. https://news.ycombinator.com/item?id=19980440

Apart from being fun, there is a good amount of engineering in designing kites.

For example, NASA has been experimenting with designing simple parachutes [1] and it turned out that the parawings (or Rogallo wings) are pretty good traction kites, too. The NPW kites are still popular kites as they are cheap to make and long-wearing in use.

Hi, I work for a small company creating insurance software (dealing with lots of insurance policy documents, offers, legal documents, etc). I created this library to make creating and editing document templates easier. Now we can turn a custumer's document into a document template in just minutes.

I wrote the core of the library in Clojure. It turned out that Clojure's data.xml is a great way to deal with immutable XML trees.
