   • Returning files sorted by creation time.

     $files = collect(\File::files($realDirectory))
         ->filter(function(\SplFileInfo $file) {
             return strpos($file->getFileName(), "{$this->fileName}");
         })->sortBy(function (\SplFileInfo $file) {
             return $file->getCTime();
         }, SORT_NUMERIC)->map(function (\SplFileInfo $file) {
             return [
                 'base' => $file->getBasename(),
                 'name' => $file->getFilename(),
                 'created' => $file->getCTime(),
                 'modified' => $file->getMTime(),
                 'size' => $file->getSize(),
             ];
         });

   • Git: How to find a deleted file in the project commit history? - Stack Overflow

   • Needed to get directories from my dotfiles using yadm as the PHPStorm license was no longer active.

     • yadm log --all --full-history -- **/thefile.*
   • PHPStorm reverts the perpetual fallback license to 2018.1 when I was currently on 2019.1, annoying as everloving shit.

   • Numbers

     • 2 / 2 = 1.0? Division seems to coerce to floats
     • div() returns the divisor or 2, not 2.5. It's an integer
     • rem() returns the remainder or 1, not 0.5. The .5 is dividing the remainder by 2.
     • (2 * 2.0) = 4.0 as the types coerce the result
     • Float.round(1.2) === round(1.2) == false

     • Individual digits builds an array, not count of digits.

       • i.e. Use that fancy peek feature to determine what each method is doing before blindly answering.
     • Remaining unparsable portion counts the space.
     • Integer.parse returns the unparsable part as a string ".2"
     • Float.ciel seems to round > 0 up to the next integer, even 0.25
   • Atoms

   • Tuples

     • List.delete_at is zero-based or more importantly pretty much all these methods are zero based to match array indexes
   • Lists

   • Keyword Lists koan.

     • It's interesting that it's foo: like json but the tuple reads :foo
     • {:foo , "bar"} Needs the space after :foo

MySQL

   • Use MySQL JSON field in Laravel - QCode
   • Laravel/MySQL JSON documents faster lookup using generated columns - Mohamed Said

Specifically using JSON fields as virtual calculations versus setting an explicit string/integer field and filling it in that way. This way we only store the JSON and the rest is done for us.

   • Strings

VSCode usage patterns

• Highlighting the method name like Integer.is_odd gives the definition (hell yes).

  • Peek reminds me of PHPStorm.

   • Initially tried using my elixir version but ran into minor issues

     • Changes the file mix.lock due to differences in runtime.
     • Various warnings that come up in the official docker image.
   • Equalities

   • Prepped git repository for common changes and using a feature/pass_1 branch to show our first pass.

     Erlang/OTP 21 [erts-10.2.3] [source] [64-bit] [smp:8:8] [ds:8:8:10] [async-threads:1] [hipe] [dtrace]

Phoenix Framework

1. Mon Feb 25

   • Initial commit + changes to .gitignore for VSCode integration
   • Added editorconfig from .editorconfig for Elixir projects · GitHub
   • Added medicine page and route
   • Added scoped api/v1 routes per Routing – Phoenix v1.4.1

2. Tue Feb 26

   • Created self-signed certificate via mix phx.gen.cert

   • Added self-signed port to dev config

     • Unlike valet these self-signed certs are a major eyesore.
   • Added force_ssl configuration though I'm unsure if it's working correctly

   • Changed medicine route to a resource. Added show method and initial view.

     • It took way too long to figure out the <%= @medicine.id %> syntax. The key is the @ symbol.
     • This likely gets easier as I move through the guide.

   • Added title from layout view. Will want to make it Supple - Page dynamically as you move about the app

     • This will seem a little tricky but I suspect it's doable.
