Earlier quoted context omitted.

`where` is intuitive as a synonym for `filter`, but it's the `select` that always threw me as a synonym for `map`. I get that they're trying to expose an SQL-like API, but yeah, map is always about mutation, but `select`only does mutation sometimes in SQL.

`Where` at least answers the question "does filter _keep_ the things matching the predicate or _remove_ the things matching the predicate" - my pet hate with the .NET naming is `SelectMany` over `flatmap`.

I love Ruby and great to see Ruby love on hacker news. Just curious on how popular it is in the hacker news community ?

I only ever tried out a rails tutorial once, and coming from a C/C++ background, but having used with many languages, too many things felt like magic back then, but no further experience with the language itself, so can’t really judge it. However, now I’m on the operational side of things, and there are 2 types of applications I avoid to deploy/maintain, mainly because of their runtime: Java and Ruby apps. It’s very…

I wouldn't call Ruby a high performance language, but your experience seems weird. Even four or five years ago I would consider Ruby one of the most painless languages for dealing with upgrades and new versions of things: install ruby with a version management tool, install your app from gemfile, run your tests, good to go. I regard it at one of the first languages to have effective tools for dealing with versioning and upgrades. I still find it easier to deal with than Python by a solid amount.

Reminds me of http://harmful.cat-v.org/software/ruby/rails/is-a-ghetto . "The main Rails application that DHH created required restarting ~400 times/day. That’s a production application that can’t stay up for more than 4 minutes on average."

Not that Ruby = rails

Am I alone in saying; for some damn reason, I don't like Ruby.. I appreciate what it can do, and indeed what it does.. I just feel like I slipped in between that moment to appreciate it more. I will go and spend some time to learn it more but out of a novelty aspect.. And that makes me feel bad.

I find it more productive, intuitive, and painless than the major scripting languages (PHP, JS, Python...), but it's definitely a bit different and less popular (given Python and JS are insanely popular).

So now there are basically no dynamically typed languages left. There's Scheme, JavaScript, what else? All languages nowadays are converging to TypeScript/Rust. It's kind of sad.

Static typing seems like the underdog outside of Java EE/big enterprise stuff.

A matter of perspective, I suppose. You seem to like dynamic typing so static typing seems ubiquitous and inescapable. I find dynamic typing completely infuriating over 100 lines or so, and dynamic typing seems inescapable.

Others have pointed out the big dynamically typed languages, so I won't rehash, but suffice it to say, there basically are some dynamically typed languages left.

Much as I would love to believe Ruby 3.0 delivers some kind of speed bump my simple test of doing what Ruby supposedly does best - parsing a log file with a regex - shows Ruby 16% slower than the Python equivalent. Ruby puts IO.foreach('logs1.txt').grep /\b\w{15}\b/ Python from re import compile with open('logs1.txt', 'r') as fh: regex = compile(r'\b\w{15}\b') for line in fh: if regex.search(line): print(line, end=''…

But it’s a super easy to read one-liner in Ruby!

You know I've long stopped caring about how popular a language is in the community. As I get older the question I ask myself is do I honestly enjoy using it? If the answer is yes, then I put it in my programming toolbox and ignore the hype.

Love the attitude, but sometimes it is not beneficial to stick to a programming language that you simply like if you need to make a living out of it. If a programming language is decreasing in popularity it becomes harder to get work. If a programming language is not popular but it has a niche and one is in that niche then it's all good.

I hate deploying Ruby and Python because all the system packages they tend to use. Getting something working typically involves a bunch of crash/install cycles and some manual compilation and package downgrading.

Go is easiest if we're talking about pre compiled binaries. If you include builds, dependency hell is real.

C#, JS, and Java have been easy for me. Install JVM/CLR/Node and run one command. Old school Java with EE servers and Tomcat and such was a nightmare but everything I've done recently is self hosting

I left Ruby because the performance and security weren't improving and the community was slowly dying. I delved into Go before that got flooded with newbs, then looked at Crystal and Pony, before settling on Rust and Haskell for most things.
