1. Set "Use full resolution for Retina display" in the VM's Settings > Display
2. Run this command in Terminal sudo defaults write /Library/Preferences/com.apple.windowserver.plist DisplayResolutionEnabled -bool true
3. In System Preferences, set the display to "scaled" using the resolution 1292 x 807 (HiDPI)
4. Enjoy.

The Indexed State Monad in Haskell, Scala, and C#

Have you ever had to write code that made a complex series of succesive modifications to a single piece of mutable state? (Almost certainly yes.)

Did you ever wish you could make the compiler tell you if a particular operation on the state was illegal at a given point in the modifications? (If you're a fan of static typing, probably yes.)

If that's the case, the indexed state monad can help!

An ongoing project to catalogue all of these sneaky, hidden, bleeding edge selectors as I prepare my JSConf EU 2012 talk.

Everything is broken up by tag, but within each the selectors aren't particularly ordered.

I have not tested/verified all of these. Have I missed some or got it wrong? Let me know. - A

A friendly reminder that you may need to set this property on your target/selected element to get the styling results you want:

-webkit-appearance:none;
