Tried @marcoroth.dev's Herb VS Code extension and loved it:
- inline display of parsing errors
- format on save
- `herb analyze` finds issues across files
I'm sure there's more, but these are the big ones that I used effortlessly in my first 5 minutes with it. Very nice!

More cool Ruby gems, this time related to databases and Active Record!
First, alternatives to Active Record 😉
github.com/jeremyevans/... – from the creator of Roda; why not try out both together?
github.com/rom-rb/rom – from the creators of Hanami; again, it's worth exploring both

Q for Ruby folks: do a lot of people still use Pry nowadays?
The old Rails app at work uses Pry, but for personal stuff I use the debug gem (github.com/ruby/debug), which seems just as capable to me 🤷

Frozen String Literals: Past, Present, Future?

The book Metaprogramming Ruby 2 explains something that I couldn't have articulated before.
`module`, `class`, and `def` form "scope gates", across which local variables are out of scope.
But you can "flatten the scope" by dynamically defining a module, class, or method: github.com/khusnetdinov...
