There's noway that this is going to be practical within the current laws of physics. You can't use a wide beam to cover an area because the amount of energy available drops by orde…

Does anyone know how you actually use this? I built the project and ran it then enabled Bluetooth on my Mac and iPhone somewhat expecting to receive a notification of the iBeacon b…

One big hole in this theory is that its been widely reported [1] that a transponder was switched off before the pilots last radio contact. The pilots would have had no reason to pu…

Also interesting is the amount of damage being done to the wheels as it drives around up there. Some good pictures of that here[1]. Apparently the wheels are designed to leave a ma…

Absolutely agree, free software has so much to offer and yet here we see it being promoted using the most desperate and ineffective means possible: dressing up in costumes and hand…

Alright, but how do you explain the instructor who had 3,200 hours on the 777 who was sitting beside the pilot not making any mention of a too low airspeed or incorrect landing con…

Thanks. Really glad you're enjoying it. The code is a real mess, but I'm hoping to gradually improve it now it's open source.

This is amazing. The UI is absolutely gorgeous. A few minor things I noticed: -Scrolling seems very laggy when scrolling with the mouse wheel, although dragging with the scrollbar …

You're welcome :) I'd love to see some other platforms supported as well.

Yep, it's for messaging using Dropbox shared folders.

Hi HNers - I posted the below explanation to GitHub but I'm reposting it below as well in case you don't see it: I originally did this project as a Mac app that I was intending to …

Fun fact: If you stacked this many iPhones screen to back on top of each other the stack would be at least 82 times the height of the worlds tallest building[1] (assuming they were…

This reminds me of Quartz Composer[1] in a lot of ways: you wire the inputs and outputs of a bunch of different nodes together (called patches in QC) and each patch gets you a step…

Everything I've heard about Nest contradicts this. I'd love to hear in more detail why this didn't work out.

Sounds like the writings been on the wall for a while now. They were fined by the CFTC in late 2012 and had to withdraw from the US market for not being a licensed exchange [1]. Mo…

All engineering involves trade-offs. Ideally, we'd prefer to have maintainable code that ships on time, but this usually isn't possible. So you have to look at how much payoff you'…
