Pony Considerations

If you're thinking of checking out the Pony programming language, here's a list of things that I think are important to know. This list is based on a Tweet that I wrote.

Editor/IDE support

There are Pony packages for several popular editors.

This is a Pony reimplementation of the C example from the SQLite quickstart page (, using Pony's FFI system ( In writing it I found a bug in Pony (which was subsequently fixed), so the exercise was good for something other than just learning. I'm still learning Pony…

BLOGPOST Just Say "No" to "Just
View gist:8302694

Recently I've been trying to modify the way that I use the word "just" when I'm at work. Merriam Webster offers a few definitions of the word; the one I'm interested in is the one that means "only", "simply", and to a lesser extent "exactly". I've been working on a new project that involves integrating a number of systems, and as I began rolling pieces out I received a lot a questions in the form of "Couldn't you just ...?" These annoyed me at first, but as I thought about it I realized I often asked questions in the same way, so I began to examine the word and the way I use it.
