Penenberg: Certainly, besides a nice chunk of change, Flickr has brought you a level of fame.

Fake: I design Web sites, its not like I'm Angelina Jolie. I think you need to tune that stuff out, otherwise you're never going to be able to build stuff, be an entrepreneur, take risks, fail. That's part of entrepreneurialism, being able to launch a stupid IM client. The hardest part about Flickr being successful is wanting to do it again. I think there's a benefit to being one of six people that no one knew. No VCs would return our calls and we were broke and bootstrapping it and operating under the radar so we could focus on the most important things: the product, the users, what we were building. There's all this noise, the tech-crunch, which you have to tune out if you want to build good product. None of that stuff is additive; it all takes away from building a product. You try a lot of things and you don't know what the hell you're doing. If you're actually inventing something you shouldn't know what you're doing.

Think you know everything there is to know about OS X? Here’s a list of secret features and shortcuts known only by the most elite nerds. Test your knowledge and see if you are a good candidate to stand at the Genius Bar and wear a clever T-shirt.

We’ll start with some simple features before moving on to the more obscure. Topics covered include downloading YouTube videos using Safari, accessing an entire second clipboard, placing widgets on your desktop, and taking control of your system volume!

Screenshots

Everyone knows that OS X has built-in screenshot functionality, but few are aware of how deep the functionality actually runs. Here’s a rundown of all the shortcuts:

⌘+Shift+3 (Full Screen)
⌘+Shift+Ctrl+3 (Full Screen to Clipboard)
⌘+Shift+4 (Selection)

• Hold option to grow selection from center
• Hold shift to lock in the vertical or horizontal position
• Hold space to move the selection while locking the aspect ratio
• Hold shift + space to lock in horizontal or vertical while moving the locked selection
• Hit “esc” or ⌘+Period to cancel
• Hit space to grab a window

⌘+Shift+Ctrl+4 (Selection to Clipboard)

• Hit space to grab a window
• Hold option to grow selection from center
• Hold shift to lock in the vertical or horizontal position
• Hold space to move the selection while locking the aspect ratio
• Hold shift + space to lock in horizontal or vertical while moving the locked selection
• Hit “esc” or ⌘+Period to cancel

To change the format of the screenshot, type the following into Terminal:

defaults write com.apple.screencapture type png
killall SystemUIServer

The default is png, but you can replace this with jpg, pdf, tiff, etc.

To change the default location of the screenshot file, type the following into Terminal:

defaults write com.apple.screencapture location /Users/Josh/Documents/Screenshots
killall SystemUIServer

Just replace the path with your own desired destination.

Gothiness: 8 Sweatiness: 9
Yup, that's St Barack, and that's the Spanish PM, and those are his children. His totally, all out Goth-rocking progeny. As teenage Spaniards it is their duty (their DUTY I tell you) to dress this way. Next year they'll be taking a world tour of Goth heritage sites as part of a cultural exchange. They will bring delicious tapas and backpacks with cuddly bears on the zips, and we'll flog them dodgy bangles from Camden Market that make your skin go green.
