We should use a type parameter with a context bound (e.g. F[_]: Sync) in library code so users can choose their IO monad, but we should use a concrete IO monad in application code.
If you're writing a library that makes use of effects, it makes sense to use the cats-effect type classes so users can choose their IO monad (IO, ZIO, Monix Task, etc).
So instead of
| sealed trait ApiModel | |
| case class ClickData( | |
| cid: String, // GA client id | |
| timestamp: Option[Long] | |
| ) extends ApiModel | |
| object ApiModel extends DefaultJsonProtocol { | |
| implicit val ClickDataFormat = jsonFormat2(ClickData) | |
| } |

The repository for the assignment is public and Github does not allow the creation of private forks for public repositories.
The correct way of creating a private frok by duplicating the repo is documented here.
For this assignment the commands are:
git clone --bare [email protected]:usi-systems/easytrace.git

Convert your ruby app to run on JRuby (often fairly painless) then deploy it by generating a JAR file (should be reasonably painless) and copying it to the servers you're running on (should be bordering on trivial).
If you've never done Java programming, a JAR is a "Java ARchive" file which is basically a single ZIP file containing all the stuff your app needs to run. So you can install java on a new machine and copy the JAR file onto it, and you're ready to go.
The usual way of deploying a Ruby app is to write (or copypasta) some Capistrano recipes to have the production machines check it out from a git repo then build it in exactly the same way you do on your Mac. This has downsides:
| App configuration in environment variables: for and against | |
| For (some of these as per the 12 factor principles) | |
| 1) they are are easy to change between deploys without changing any code | |
| 2) unlike config files, there is little chance of them being checked | |
| into the code repo accidentally | |
| 3) unlike custom config files, or other config mechanisms such as Java |
