copy/delete word under cursor in Vim
yw / byw

Assuming that the cursor is at the first character of the word simply do this in command mode:
     yw
y is for yank and w is for word.

Other ways of doing the same thing which are not as efficient:
     vey
the v starts visual select mode. e tells vim to move to end of word. y yanks or copies the word. to delete replace y with x.

Sketchapp fro MacOS is a fantastic tool for prototyping, but has some drawbacks that make converting designs to fully functional websites a pain.
One of these is sketchapp's line-height, which doesn't seem to have any relation to CSS line-height values.
This is a simple example of how we can take a line height value from sketch and apply it to a CSS class for styling text:

Lets assume the text in our Sketchapp prototype has a font size of "18px", and line height of "33"...

Our CSS class would look like this:

Pushing to Multiple Git Repos

If a project has to have multiple git repos (e.g. Bitbucket and Github) then it's better that they remain in sync.

Usually this would involve pushing each branch to each repo in turn, but actually Git allows pushing to multiple repos in one go.

If in doubt about what git is doing when you run these commands, just

Unfortunately, the Cisco AnyConnect client for Mac conflicts with Pow. And by "conflicts", I mean it causes a grey-screen-of-death kernel panic anytime you connect to the VPN and Pow is installed.

As an alternative, there is OpenConnect, a command-line client for Cisco's AnyConnect SSL VPN.

Here's how to get it set up on Mac OS X:

1. OpenConnect can be installed via homebrew:

    brew update
   

brew install openconnect
