Let the hive mind of Engadget get that for you.
"I finally got a new laptop with a lone USB 3.0 port. I'm now looking at getting a USB 3.0 hub with a power adapter so I can use both of my USB 3.0 hard drives at faster speeds. I've read lots of horror stories where some hubs either don't come with power adapters -- and as a consequence the portable drives don't work with them properly -- or they are designed poorly which results in USB 2.0 speeds. Or, the hard drives keep getting disconnected. Do your readers have any suggestions or experience using USB 3.0 hubs? Thanks!"
Y'know.. that'd be really handy.
Most people drown either during the unpatrolled hours (6pm - 7am) or at unpatrolled beaches, I can see this coming in handy for the unpatrolled beaches (assuming the cameras would be useless at night).
I'm a regular voluntary lifesaver on the Gold Coast, and had no idea that in other beaches around Australia they didnt have as many sets of Flags set up for people to swim in. Seriously, during the on-season here you walk 300m and you hit the next patrolled area (prolly 700-1000m during the off-season).
I did some travelling these holidays and in some parts, there were no patrolled areas at all along an entire stretch of beach! Not that that stopped us going in for a swim but I figured, when I saw all of my friends dive straight into a rip, that it's these places that can't be regularly patrolled and thus, people drown at.
Hence, a bunch of cheap cameras would definately help in monitoring these places. I can only dream of them being able to track people entering the water and raising an alarm if they dont come out again, or if they get "lost" for a period of time. That would require almost complete coverage of a beach though, which would be fairly costly.
By the way, on sharks, unless there are a fair few people around (or the beach is patrolled), I get quite antsy swimming too far out just in case. I know if I'm between the flags that someones there keeping an eye out (if not several eyes) and can be out in an instant in some form of boat to help. Swimming alone, at an unpatrolled beach, in the middle of nowhere, is just asking for trouble.
And while Im on the subject of marine life, #16, you watch too much Discovery Channel :P That kind of marine life only lives waaay up north (if you find a map of Australia, look at Queensland and draw a line around halfway up, from there to the top are where your Box Jellyfish and Sea Snakes live).
Regardless, paralasys and death are only possible if you're not treated, and you'd have to be pretty silly to be swimming *alone* in a place you *know* there's a possibility you could be in trouble *away* from any lifeguards.
PS. #14, with 85% accuracy it means that if 1 in 100 people drown, there's an 85% chance that they'll be "seen" and monitored. Whether the system realises they're drowning (or can notify someone in time) is seemingly still to be developed.
Cheers.
