Note: you can now configure this simply in iTerm2's application settings. Go to Preferences > Appearance > System and select "Exclude from Dock and ⌘-Tab Application Switcher".

On my dual-drive MacBook Pro I have remapped the eject key to F13 using Karabiner and NoEjectDelay. The eject key has been assigned as the hotkey for a guake-style visor terminal using iTerm2. Having its own hotkey precludes the need for an icon, so I prefer to hide the iTerm dock icon.

To hide the dock icon of iTerm2 on Mac OS X:

/usr/libexec/PlistBuddy -c 'Add :LSUIElement bool true' /Applications/iTerm.app/Contents/Info.plist

Linux Backup Solutions

I've been looking for the best Linux backup system, and also reading lots of HN comments.

Instead of putting pros and cons of every backup system I'll just list some deal-breakers which would disqualify them.

Also I would like that you, the HN community, would add more deal breakers for these or other backup systems if you know some more and at the same time, if you have data to disprove some of the deal-breakers listed here (benchmarks, info about something being true for older releases but is fixed on newer releases), please share it so that I can edit this list accordingly.

• It has a lot of management overhead and that's a problem if you don't have time for a full time backup administrator.

A Guide to Functional Programming Lingo for JavaScripters

Functional programming gets a bad wrap about being too hard for mere mortals to comprehend. This is nonsense. The concepts are actually quite simple to grasp.

The jargon is the hardest part. A lot of that vocabulary comes from a specialized field of mathematical study called category theory (with a liberal sprinkling of type theory and abstract algebra). This sounds a lot scarier than it is. You can do this!

All examples using ES6 syntax. wrap (foo) => bar means:

function wrap (foo) {

Styling native elements

Native HTML controls are a challenge to style. You can style any element in the web platform that uses Shadow DOM with a pseudo element ::pseudo-element or the /deep/ path selector.

video::webkit-media-controls-timeline {
  background-color: lime;
}

video /deep/ input[type=range] {
