1. How about heat from flexing that lowers the stiffness and allows more the top of the band to sag as speed increases. If this test was properly designed however, the sag from this effect would be countered by #2 below:
2. Doing this test in a drum means that there's no airflow over the top of the rubber band. If the band was rolling downhill at speed, the top of the rubber band would acquire an attached airflow creating lift due to the bernoulli effect. This would cause the top of the rubber band to bow upwards.
I'm amazed that no mention or consideration is made of either of these points.
There are many personal locator devices available. The factors that make them either useful or useless are 1) The accuracy and ability to get a position fix of their GPS receiver, and 2) The ability of the device to communicate the position information to the central monitoring system used to track the device.
The cost of this device, several hundred US dollars, puts it in the range of low-end personal locator devices like the SPOT personal locator, which has a low-sensitivity GPS chipset and which uses Satellites to relay the position information. Low-end personal locators have very short battery life and generally provide hit-and-miss location tracking. I don't know how this kids-device communicates, but it seems to me that it can't have very good GPS-sensitivity, battery-life, or communications-power.
I'd love to have one of these on my toddler when we go to the State Fair, or other crowded outdoor events, but I'd like to see an extensive test and review of any device like this before I add it to the tools I use to protect my child.
So far the product (update) does seem to work great. Better than the previous version. I use the Calc program a lot, and it seems faster on some basic functions like loading files with forumulas.
In our shop it is also clear how easy the preparation is. The real issue is getting the suits to cut through the memo bs that's a prereq for everything in order to put in the fixes.
If this is true, what do they do about inmate populations in jails and prisons? Incarcerated persons often get no direct sunlight exposure. It will be interesting to see if changes are made.
I agree, echoes are bad, but I've read that the new parallel chipsets use error correction algorithms and will incorporate echoed or multipath signals into their calculation with reduced weight, rather than ignoring them entirely, as serial chipsets do.
We use GPS units to geocache, and accuracy has strangely seemed to have improved over the Summer. For those unfamiliar with GPS receiver tech, the newly available units use fast, parallel processing to greatly improve real-time sat processing. The new receiver chipsets have been problematic to use because they couldn't seem to get enough info and used echoed signals often in effort to increase accuracy. Maybe this update will put more downward bandwidth out there to help the new GPS receivers meet their potential.
This may be redundant, but how much more does it need before it's the whole shebang? Network, a bit more RAM and an App CPU and you're home.
But coffee spills... Oh the Humanity!

Aren't these the same crabs that make rich men out of entire crews who risk their lives working on fishing boats in Alaska?
At my local grocer, I can buy a pound of king crab when it's on sale for around $20. I figure a 55 gallon barrel of these guys would weigh close to 500 pounds. Barrel of Sweet Light Crude goes for about $70. Barrel of Sweet Light Crab goes for $10,000. Hmmm... Is there some secret crab cartel, the Alaskan subsidiary of DeBeers, or maybe the Illuminati, arti-fish-ally controlling the market of my favorite crustacean?
The best way I've found to clean an already infected PC is to go to www.ubcd4win.com and download and build an Ultimate Boot CD for Windows.
This way, you boot from the CD, with the OS offline. Then you can update and use the ubcd4win built in antivirus and antispyware utils to clean your system. This has worked every time for us.
Only my opinion, but as the handheld communicators, which are pay-as-you-go or monthly-fee based gain marketshare and computing power, maybe Microsoft is quietly preparing for battle in what may become the 'standard pc' for most users.
Hi, I'd need the camera in front of me, but I'll post what I remember.
Set the camera for the highest resolution possible. Turn off all the automatic settings. Turn off any 'digital' zoom features. If your camera has an 'optical' zoom set that as high as it will go. I don't know the technical terms for camera settings, but set focus to infinity and the shutter speed as slow as possible or if you can, set a timed exposure of a full second or more and use the cam's timer to snap the shot although my parents' cam wouldn't do that so I had to press the shutter button which gave me one out of 3 pictures that weren't fuzzy from my shakiness. You want to capture as much light as you can at as high a resolution as possible. You are leveraging the sensitivity and high resolution of the cam's optical sensor. You may have to experiment with this, but when you get it right you can 'magnify' your picture in any good photo editor and gain amazing 'telescopic' views of celestial objects.
Hope this works for you as well as it does for me. Search the web for digital astrophotography. Most sites assume you have a telescope, but you don't need one! You can find cam-specific settings at these sites and go shoot without the scope.
The array method these guys used is the principle for the Very Large Base Array on Mauna Kea. Interesting that they're still working to get the VLBA software working, and these guys in the FA are finding planets.

Ok, At least two problems with this analysis.
1. How about heat from flexing that lowers the stiffness and allows more the top of the band to sag as speed increases. If this test was properly designed however, the sag from this effect would be countered by #2 below:
2. Doing this test in a drum means that there's no airflow over the top of the rubber band. If the band was rolling downhill at speed, the top of the rubber band would acquire an attached airflow creating lift due to the bernoulli effect. This would cause the top of the rubber band to bow upwards.

The speed dial feature is nice. I'm seeing Opera handling non-mobile-formatted sites better (for me) than Safari.
Just my .02
You're right. This is big enough to spend some money on data recovery. Especially the mechanism so they can identify the perp.

Would be if Conficker does nothing after all the man-hours spent preparing for it.
This article is making me smile.

Well thank you for confirming my benevolent conspiracy theory! But would more Sats improve the new receivers' performance? Thanks for any info -
well that's why ABEND isn't in the Scrabble dictionary and ASCII is...

Very nearly as funny as Monty Python's 'killer joke.'

Aaaaaagh!
Bravo! I was looking for the joke that you found. You ciphered it.
But didn't you mean Canarydactyl?
Who wants to play Mario Brothers and not be able to jump over owls, turtles, and spiny creatures?
Snorted a granola bar through my 2 meganostrils on that one.
