The best Rails codebases are the ones who have ample "vanilla" Ruby and just happen to use Rails alongside said Ruby.

Judging by listings in the month jobs posting, the vast majority of hiring companies won't look at you if you don't have immediate and long experience with their current tech stack.
Back in my late 20s, I got stuck on maintaining a legacy software system written in Ada95 (I was unemployed in 2008 and it was the only work I could find). When that job went away, I thought I could get a job using something more modern. However, the only job I was able to land was a new development project in Ada2005 (actually it was a port from SPARC to x64 and a partial rewrite of the same legacy application I had…
What I need to know is if you can think critically, not if you already know what we plan to teach.

Ruby used functionally is great, but it takes an already time-inefficient language and amplifies that weakness (lots of creating new collections and returning them, whereas normally in Ruby you would modify elements within the collection).
Isn’t there something called LazyEnumerator that deals with this? In terms of chained .map at least
a = (1..1000).lazy.select(&:even?).map{|i| i*2 }.map{|i| i + 1 }.map(&:to_s).map(&:reverse)

Not OP but in my limited experience the MVP slot is mostly held by Django, with Node + typescript, Go and Elixir being the “safer, faster” variants “kids” are using.
Ha it's funny seeing Django in that list because back in day (10 years ago or so) before rails took over I was trying to get everyone to use Django at my job. Then rails exploded and I moved to that. I honestly thought Django was mostly dead now.

Ruby is still a beautiful language, particularly for its object oriented-ness. And I think Ruby's nature, simplicity and power appeals to young people, however the resurgence of a towering Javascript/NodeJS is hard compete with. These are market forces that really matter when you're wondering what language & platform to use for your MVP. In recent surveys, Ruby & Rails has fallen to the bottom of the list among the f…
Ruby also suffers from top quality JITs vs what JS has. The only good option being JRuby, as far as I understand. I am not at all into Ruby. Regarding being polyglot and seniority, a possible solution is to work for consulting companies that focus on multiple stacks.
In the "things learned from Ruby" section: Focus on strong object oriented programming What I've learned from Ruby is to favor functional programming concepts - minimize side effects, isolate state mutation, etc. Ruby is definitely OO, but when my Ruby code is more functional it's less buggy, easier to understand and move around, and generally less convoluted.
Like Gary Bernhardt's notion of a "Functional Core, Imperative Shell" — https://www.destroyallsoftware.com/screencasts/catalog/funct...
Clojure does not have an alien syntax. As with Lisps in general, it has almost no syntax. (operator param param ...) Done.
It has much more syntax than any other Lisp I know, and it seems alien even coming from Common Lisp. In addition to the usual (list) and 'quote and `backtick and :keyword and ;comment, it has [vector] and {map} and #{set} and #(function) and @deref and #"regex" and ^metadata and #?(:conditional) and ... (Yes, several of those are implemented as reader macros. I don't see how that would make them any easier to learn t…
I've tried a lot of different languages over the years including Ruby, Go, Scala, and Haskell. Ruby actually isn't too bad if you don't use Rails. Between Rails and stuff like Spring over in Java-land I've developed a strong hatred of huge frameworks :) Clojure, however, is the one language that just 'clicked' for me almost immediately. In fact, I'm pretty certain I'll be sticking to Lisps as much as possible from he…
Over on Reddit[0] one of the problems for newbies to Clojure is not knowing what to use for web development.
