Is ruby used outside of web dev (i.e., Ruby on Rails)? it seems like a nice cute language but I almost never hear about it.

At my day job we use Ruby with Sorbet to stitch together a large number of data engineering pipelines. It's a good choice since we also often stand up small Rails apps to expose the results from those pipelines, so we can keep everything in one language. The fluent functional approach it enables is pretty nice for that business logic (but I would not want to do it without the gradual typing on top). We do find oursel…

The default block parameter name seems small, but I feel like I'm gonna use it all the time, especially when I'm in the Rails console just trying to debug data

I constantly run into situations where I need to nest an iterator computation, and things like "it" get confusing. I'm all for adding language features to avoid boilerplate, and it's clearly useful. I just want to call out that anonymous typing can be polarizing in large codebases and maybe only use it sparingly.

Yeah, I use it for everything between 5-lines-of-bash and a needs-a-compiled-language. You almost never hear about it, because it's mature. No big controversies, no huge fuckups or new versions that break everything, just a steady trickle of improvements.

The author also forgot to mention that the new error output doesn't mix ` and ' anymore. Ruby 3.3 > 'asd' + 1 (sitar-report):1:in `+': no implicit conversion ... Ruby 3.4 > 'asd' + 1 (sitar-report):1:in 'String#+': no implicit conversion...

Rather than specifying a name in trivial cases like the one above, you can now write: > [ > "beige chinos", > "blue jorts", > "rainbow jorts", > ].filter { it =~ /jorts/ } > # => ["blue jorts", "rainbow jorts"] This reminds me of Perl's $_ (which in Ruby is last line read from STDIN).

I am familiar with ‘it’ as a default closure input from Kotlin. From a quick search, that in turns seems to be inspired by Groovy.
