The wallet is effectively created by the first transaction that sends the money into it. However, if you used a random public key instead of creating a proper public+private pair, tough luck brute forcing the private key from the randomly chosen public one.

We had some fun with this when first full-duplex sound cards finally arrived. It won't totally stop you from talking, but it makes you stutter uncontrollably.

These futures are cash settled, not deliverable.

RPi 4 can drive two 4k displays, but only at 30 Hz refresh rate.

on a Nexus 5X, on the "select the backup to restore from" screen, the only control that reacted to tapping was the "skip restore" button. Observed on two different handsets, with different OS patchlevels. After that, the device created a new backup, letting the old one expire. So the guy possibly just avoided getting Google-trolled :)

I see what you did there, but Emacs' codebase is actually quite small by today's standards.

There are tools to deal with them, and were even recently featured on Slashdot: http://news.slashdot.org/story/13/01/07/1551231/netflix-open-sources-janitor-monkey-aws-cleanup-tool

Almost all cellphones today come with a hands-free headset. I actually used it during an interview with Facebook, and had zero problems typing and speaking at the same time, although they didn't hire me either. I don't blame the headset though :)

Also, according to their measurements, the conclusion should be more like "There's almost no point in spending $50 on a sound card, if you care only about playback, not recording."

Indeed, if the disk could be also read the same way like MO disks, it would be promising: http://en.wikipedia.org/wiki/Magneto-optic_Kerr_effect

I suppose the salt only takes part in the manufacturing process, and is removed afterwards.

If your friend works in the academia (from the currency mentioned, I assume you are from Europe), she can also try applying for an access to HPC-Europa infrastructure.

Considering the bytecode didn't change between Java 6 and 7, they can just watch and get all the Java 7 benefits for free.

Indeed. Like the internet. Or space flight. Or cell phones.
