The goal is to "engineer software-based radios that transmit data faster than a competitor using identical hardware".

The goal isn't to develop fancy new hardware, or to use an overwhelming amount of power. The goal is to develop fancy new software.

With frequency-hopping and time-hopping techniques, if you can intelligently adapt to the local interference, and transmit in the time and frequency gaps where the interference doesn't occur, then you can transmit more data for the same amount of power. That's the goal.

This tool extracts the keys from RAM dumps. There are free tools that do this too, of course.

But isn't it difficult to get a RAM dump, you say? Not really:

  • Hibernating a computer writes this data to disk. Starting in Windows 8, "shutdown" actually writes some hibernate data by default.
  • VMs also have their own suspend functionality that does a RAM dump, as well as non-SAN VM migration.
  • Firewire ports actually allow devices to scan RAM of the machine they're connected to.
  • Obviously, if you have access to a live machine, you can get the keys directly from RAM.

Interesting fact — There's an 85% fatality rate for the speed record for any boat. This sport is extremely dangerous.

The sailing speed record is 80% slower than the overall boat record, so the sailing record is a little safer. Nonetheless, one of the SailRocket crashes led to the pilot having a broken helmet.

First time accepted submitter abhi2012 writes "Noah Kagan, a former Facebook product manager, has written a brutally honest article about how and why he got fired from Facebook in 2006 and what he learned from it. The experience must be particularly painful, given that it eventually cost Kagan a $100 million fortune."

I had Prey installed on my son's laptop, which was stolen along with a bunch of other things. After I told Prey it was stolen, we got a geolocation hit in a nearby town with the name of the hotel in the WiFi. The local police went out at midnight and collected it all for us. We drove over in the morning and brought them brownies.

I recently had a great experience with police. We had a break-in, and all the laptops were stolen. Fortunately we had Prey on one of them, and it tracked the thieves to a hotel in a nearby town. The local police investigated and recovered almost everything. We drove over the next day and brought them brownies.

A similar thing happened to me. My finance was signing my daughter up for a game when she put in her actual age. This purged her account completely, which was really annoying. I drilled into everyone's heads that they should always lie about their age on the Internet, which goes against my general policy of honesty.

The moral of the story is that laws have unintended consequences.

It looks like aluminum likely doesn't cause alzheimer's. There was also some evidence that high doses of zinc can cause problems.
On the other hand, a recent study suggests that too much zinc might be the problem. In this laboratory experiment, zinc caused beta amyloid from cerebrospinal fluid -- the fluid that bathes the brain -- to form clumps similar to the plaques of Alzheimer's disease.

My general rule of thumb is to stay physically active, eat well, and stay mentally sharp. Mega doses of whatever likely aren't going to help much.

Age and treachery will always overcome youth and skill.
