I just bought it. It’s a really nice game.

I have red/colour blindness and I find that the contrast between the red and green borders on cells is very low (they look quite similar to me).

It doesn’t stop my playing - it just slows me down.

It might be something you address is you find you have many players with colour blindness.

Clojure works really well for AOC.

A lot of the problems involve manipulating sets and maps, which Clojure makes really straightforward.

The recursive anchors seemed to be user-error. Either copy+paste bugs, or an anchors places in the wrong position.

The null character would appear when people try to write a string path, and use the the `~` character without quotes.

At CircleCI, we have had to handle many strange YAML documents. Two that come to mind:

A recursive document:

    key: &anchor
     - *anchor

The `~` character represents null:

    ~:
     - ~

This parses as a map of {null: [null]}

You would be surprised at how little of the code in a CI product, like CircleCI, deals with git. On the other hand, there is a lot of code required to integrate with the VCS - authn, authz, webhooks, commit-status, etc.

I have a few qualms with this app:

1. For a Linux user, you can already build such a system yourself quite trivially by getting an FTP account, mounting it locally with curlftpfs, and then using SVN or CVS on the mounted filesystem. From Windows or Mac, this FTP account could be accessed through built-in software.

2. It doesn't actually replace a USB drive. Most people I know e-mail files to themselves or host them somewhere online to be able to perform presentations, but they still carry a USB drive in case there are connectivity problems. This does not solve the connectivity issue.

3. It does not seem very "viral" or income-generating. I know this is premature at this point, but without charging users for the service, is it reasonable to expect to make money off of this?
