# FAQ

**Q:** Why `piku`?

**A:** Partly because it's supposed to run on a [Pi][pi], because it's Japanese onomatopeia for 'twitch' or 'jolt', and because I know the name will annoy some of my friends.

**Q:** Why Python/why not Go?

**A:** I actually thought about doing this in Go right off the bat, but [click][click] is so cool and I needed to have [uWSGI][uwsgi] running anyway, so I caved in. But I'm very likely to take something like [suture](https://github.com/thejerf/suture) and port this across, doing away with [uWSGI][uwsgi] altogether.

Go also (at the time) did not have a way to vendor dependencies that I was comfortable with, and that is also why Go support fell behind. Hopefully that will change soon.

**Q:** Does it run under Python 3?

**A:** Right now, it _only_ runs on Python 3, even though it can deploy apps written in both major versions. It began its development using 2.7 and using`click` for abstracting the simpler stuff, and I eventually switched over to 3.5 once it was supported in Debian Stretch and Raspbian since I wanted to make installing it on the Raspberry Pi as simple as possible.

**Q:** Why not just use `dokku`?

**A:** I used `dokku` daily for most of my personal stuff for a good while. But it relied on a number of `x64` containers that needed to be completely rebuilt for ARM, and when I decided I needed something like this (March 2016) that was barely possible - `docker` itself was not fully baked for ARM yet, and people were at the time trying to get `herokuish` and `buildstep` to build on ARM.
