I got the iOS version and I was having trouble aligning the corners on the reference object. When I lifted my finger the crosshair would jump slightly with it.

Is it possible to offer edge detection or corner snapping?

I also got much better results when I zoomed as far as possible into the image to align each corner. I think that would be a helpful tip in the app when aligning.

I can't believe the new MacBook has no internal fans.

[0] Fanless architecture

The new MacBook is the first Mac notebook ever without a fan. Since the Intel Core M chip draws only 5 watts of power and therefore generates less heat, no fan or heat pipe is required. Instead, the logic board is seated on top of an anisotropic graphite sheet, which helps disperse any heat that is generated out to the sides, all while your Mac stays virtually silent.

I've had issues in the past with macbook pro fans failing, so it's great to remove that potential mechanical failure. But I've also had issues with my macbook pro outputting an unreasonable amount of heat. I'm curious if they've solved that issue, especially now with no internal fans.

Yes, I believe it is missing a rule. If columns don't need to be identical than this 10x10 puzzle won't have a unique solution: http://i.imgur.com/ZQ8pkfm.png
