I'm slightly digressing, but I always thought it was interesting how the printed circuit board software Eagle was a combination of a graphical and text based tool. You can use the buttons like any other CAD program or you can enter com

Quick tip if you are on OS X: Pressing ctrl+command+space pops up an emoji bank so you can enter them in any text field. Now you don't have to hunt for emojis to put in the website. Love the website btw!

Nope, I'm a Macports guy as well, never had any serious problems with it. I wish it was possible to run both though because there are packages exclusive to either that I would like to run.

Minuum is great, one of the first I downloaded for iOS8. One thing that I would like to see more of is text expansion. Apple's stock keyboard has it but I don't think I've seen it in 3rd party keyboards. I also really like ge

Since there are multiple layers of paint I would guess that the wait time is for the intermediate layers, and that removing and replacing the car from the line is the expensive part.

Mount Everest is at 29000 feet, where the air pressure is 32 kPa [1], which is about a third of sea level's 101.325 kPa. People have climbed everest without supplemental oxygen, let alone a pressurized suit. I imagine that the body wou

Mavericks does amazing things to memory usage. My machine has 4GB as well, and safari went from 1GB+ memory usage to 200MB memory usage for the same amount of tabs. Under ML, I was swapping constantly; now, no swap at all.

It seems that they are using Kickstarter for preorders. They'll reach a lot more people through Kickstarter than their own site. As zacharycohn said, the money they'll get through Kickstarter is probably nothing compared to other methods.
