A curated collection of answers that Rich gave throughout the history of Clojure

Rich Already Answered That!

A list of commonly asked questions, design decisions, reasons why Clojure is the way it is as they were answered directly by Rich (even when from many years ago, those answers are pretty much valid today!). Feel free to point friends and colleagues here next time they ask (again). Answers are pasted verbatim (I've made small adjustments for readibility, but never changed a sentence) from mailing lists, articles, chats.

How to use:

  • The link in the table of content jumps at the copy of the answer on this page.
  • The link on the answer itself points back at the original post.

Ways to use VCR for a request made by a let block
# 1) Use VCR.use_cassette in your let block. This will use
# the cassette just for requests made by creating bar, not
# for anything else in your test.
let(:foo) { VCR.use_cassette("foo") { create(:bar) } }
it "uses foo" do
foo
end
# 2) Wrap the it block that uses #foo in VCR.use_cassette.

Checkout github pull requests locally

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = git@github.com:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:

Setting up and installing rbenv, ruby-build, rubies, rbenv-gemset, and bundler

This guide enables you to install (ruby-build) and use (rbenv) multiple versions of ruby, isolate project gems (gemsets and/or bundler), and automatically use appropriate combinations of rubies and gems.

Вводная часть

У CSS есть несколько базовых проблем, которые позволяют очень быстро отстрелить себе ногу при неправильном использовании:

  1. Глобальный неймспейс – в серверном программировании все что написано в файле, в файле и остается. Все же что написано в css и js засирает глобальное пространство имен со всеми вытекающими. В JS эту проблему сейчас побороли всякими модульными системами, а вот с css сложнее. В идеальном мире это должен починить Shadow DOM и настоящие Web Components, но пока их нет единственный способ с этим бороться – следовать какой-то системе именований селекторов, которая по возможности уменьшает и исключает возможные конфликты.

  2. Каскадность – если на один элемент может сработать несколько правил, то они все и сработают последовательно. Если есть элемент h1.title, на него сработают все правила для тегов h1 и все правила для класса .title. Так как весь html состоит из тегов, то правил которые п
