I upgraded the excellent asdf version manager using Homebrew and ran into a snag when trying to perform mix commands. I encounterd the error /Users/jbrayton/.asdf/shims/mix: line 13: /usr/local/Cellar/asdf/0.10.2/libexec/bin/asdf: No such file or directory. The key to notice here is the path /usr/local/Cellar/asdf/0.10.2/ when the newest version is 0.11.0, as there is clearly a mismatch. I restarted my terminal and shell, but the problem persisted. I noticed all the files in ~/.asdf/shims had the line exec /usr/local/Cellar/asdf/0.10.2/libexec/bin/asdf exec "odbcserver" "$@" # asdf_allow: ' asdf '. This line is not what we wanted and indicates the problem.

After looking at the pinned https://github.com/asdf-vm/asdf/issues/785 and then following that to https://github.com/asdf-vm/asdf/issues/1393, the solution rm -rf ~/.asdf/shims; asdf reshim fixes my problem. Now, whenever I examine one of the shim files, I see the line exec /usr/local/opt/asdf/libexec/bin/asdf exec "mix" "$@" # asdf_allow: ' asdf ' as expected. The directory /usr/local/opt is what I see when I run the command brew --prefix asdf as the prefix is no longer /usr/local/Cellar/asdf/0.10.2/ or the Cellar location. This corrective measure should be a more permanent solution moving forward as the prefix /usr/local/opt should no longer change in the future.

This issue was also somewhat of a perfect storm as Phoenix 1.7 rc.1 dropped two days ago and I had just upgraded a bunch of homebrew packages, including asdf.

Due to a comment on Hacker News (original post here), I thought I would put my money where my mouth was, so to speak, and tackle this problem in a public repository.

My comment could likely be seen as dismissive or arrogant. I get that. My biggest problem is that because people still fail, this is the interview equivalent of patty cake: awkward, childish, and unrewarding (unless you're a 2 year old).
To be quite honest, I don't quite understand my disdain for the problem. It's simple enough that it can be solved a number of ways quickly and gets you to express at least the fundamentals of development in a particular language.

This exercise is an excellent opportunity for a number of things:

1. It'll be a form of code kata and I need practice, even on something I dislike greatly.
2. Much of my work isn't public, as I often rarely see the benefit of my specific ideas being shared. I don't need to prove anything by doing this but I don't see this hurting anything.

3. If you believe my time tracking is accurate, it should demonstrate at least some proficiency in languages I know and how quickly I can at least have a basic understanding of the ones I don't.

   1. My proficiency in order is C#, PowerShell, Javascript, PHP, Pascal, then Ruby. The latter 3 don't rattle around in my brain as much as the former.
   2. F#, Objective-C, CoffeeScript, C/C++, Go, Dart, and Haskell are the planned languages I've mostly touched in passing or know about.
4. This would be a good opportunity to write tests to check the work. A neutral 3rd party would be ideal as the tests could influence the experiment.
5. It'll also give insight into my habits regarding structure and clean, concise code. I prefer readable code with very little comments because I feel the code itself should be the comment. This largely isn't possible in most code bases but it shouldn't really be a problem here.
6. To prove to myself that I don't just take examples from Google and make them my own, that I can start from scratch when I need to.

Note: I'm using https://rosettacode.org/wiki/FizzBuzz as a language guide only. If you see me follow a specific example, punch me in the nuts.

The best description of the problem can be found here, specifically (altered for this example):

Write a program that prints the numbers from 1 to 100. But for multiples of three print "Jazz" instead of the number and for the multiples of five print "Hands". For numbers which are multiples of both three and five print "JazzHands".

This brings up some excellent points. I'm definitely not above FizzBuzz or live coding but I still can't pinpoint why I have beef with this particular problem.

I honestly can't remember the last time I've actually tackled this problem so the potential to look really foolish, at least at the beginning, is pretty high.
