ssh://bbs@ptt.cc is the largest one in Taiwan with ~60k concurrent user at this moment. You'll need to switch to BIG5 encoding to display properly.

There's also a web version https://www.ptt.cc/bbs/index.html , which supports Unicode.

Swift also have them.

I don't use toggles for these common symbols like /\'[-+] . The trick is that you make the top row as same as a normal keyboard, move ]\ from second row to the bottom row as they seldom get typed (] got auto completion most of the time).

Following is my mapping. https://configure.ergodox-ez.com/ergodox-ez/layouts/zLQW4/la...

For those who want to see them or just like Nodejs. National Palace Museum(NPM) is the place to find them.

yes, the regex part handles the validation.

Not exactly the same, since there's no UInt8 in Ruby.

    require 'sinatra'
    get %r{/hello/([^/]+)/(\d+)} do |name, age|
      "Hello, #{age} year old named #{name}!"
    end

Seems like the Swift slowness comes from ARC.

The battle has not over yet. RHEL 8 has Python 2.7 in their Application Streams. So looks like Red Hat will provide security updates until Jun 2024 https://access.redhat.com/node/4079021

It's interesting to see that languages try to get features that other languages have.

In Swift they have position argument in block from the start

    users.map{$0.name}

now they want to add Ruby's &:attr feature[1]

    users.map(\.name)

Maybe the best feature user want is the one other languages have. Or this is just Blub Paradox[2] in real life.

edit: grammar

Ruby's bundler is pretty neat. It's one of the first systems that introduced lock files.

Since we can reference other requirements with `-r req-dev.txt` inside requirements.txt . Current requirements.txt isn't really machine-readable without firing up a full Python interpreter.

We can even use string interpolation

    let x = "\(number)"

It's HNed, I got 509 Bandwidth Limit Exceeded. Looking forward to play it.
