With Rails 3.0 released a few weeks ago I've migrated a few apps and I'm constantly finding useful new improvements. One such improvement is the ability to log anything in the same way that Rails internally logs ActiveRecord and ActionView. By default Rails 3 logs look slightly spiffier than those produced by Rails 2.3: (notice the second line has been cleaned up)

As the web component specs continue to be developed, there has been little information on how to test them.
In particular the /deep/
combinator has been deprecated in Shadow DOM 1.0. This is particularly painful since
most end-to-end testing frameworks rely on elements being discoverable by XPath or calls to querySelector.
Elements in Shadow DOM are selectable by neither.
Webdriver.io has the standard actions by selectors, but also allows browser executable scripts to return an element
// UPDATE: In 2023, you should probably stop using this! The narrow version of Safari that | |

* Safari 10.1 supports modules, but does not support the `nomodule` attribute - it will | |

mix3d asked for some help using this guide with windows so here we go. This was tested with Windows 10. Run all commands in Git Bash once it's installed.
Github will be the main account and bitbucket the secondary.
# First install tmux | |
brew install tmux | |
# For mouse support (for switching panes and windows) | |
# Only needed if you are using Terminal.app (iTerm has mouse support) | |
Install http://www.culater.net/software/SIMBL/SIMBL.php | |
Then install https://bitheap.org/mouseterm/ | |

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:
All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.
Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.
