It does read like an advertisement, but it is one that, as a parent, I want to read.

Oh, I agree...I should have put some more positive spin on that assessment. I have nothing against vehicle owners installing GPS in said vehicles being used by others. It's paid the bills for me in the past.

Hell, I even let them Big Brother on my car. Progressive Insurance customer here: I gladly signed up for Snapshot when it was available (and drove like a little old lady) for 45 days. Saved a permanent 14% on my annual premium without permanent monitoring.

Is this news because it's LoJack, a household name dating back to my childhood, rather than Wireless Matrix/GPS Insight/Trimble/the 47 other players in this space?

Why is this news? Is it just the consumer commoditization of what businesses have been doing for years? Vehicles + GPS + Web Interface = Big Brother? Whoopee.

I've been supporting deployments of vehicle GPS, geofences, and automatic alerts for years. Maybe that why this article is so underwhelming.

Also, it reads like an advertisement.

This! Thisthisthisthisthis. Oh man, you just made a friend in me. I was recently told by an industrial engineer here where I work that it was "more important to be a team player and get the general concepts of the integration working before we worry about the details". This is the guy who also has a Master's of Business Administration, but is unable to correctly spell "MBA". Of course, this strategic-level million-dollar project is 14 months late and has had over 22,000 defects logged.

I wonder why.

Parent was correct: same delta-v for differing masses. However, since delta-v is nothing more sophisticated than good ol' acceleration (Force x Mass), you do need more force for a greater mass to reach a given delta-v.

My question was along the lines of inducing acceleration in very low mass particles using the principles seen in a Crookes radiometer. http://en.wikipedia.org/wiki/Crookes_radiometer Possible?

For the sake of discussion, let's assume this report showed a problem orders of magnitude worse, and we were on the verge of Kessler syndrome conditions. What technologies exist today to combat the problem? (Yes, I know, no government today would unilaterally scrub space without a quid pro quo...)

If there are 19,000 trackable chunks of debris, how many untrackable (and just as deadly) small particles are there? I know that particle densities are minute. If we launched an array of satellites with Aerogel paneling, is it reasonable to expect a significant improvement in "air" quality up there?

What about that heat-ray device recently pulled our of Afghanistan? Can we launch one of those to spray microwaves tangentially to the Earth's surface? Would the heat applied to a paint-chip sized debris particle be enough to change the orbit? It doesn't take too much delta-v to alter the eccentricity of a paint fleck enough to burn up in orbit, does it?

I live in Phoenix, AZ where speed cameras were recently deactivated after two years of controversy. The same vendor, Redflex, was snapping pictures if you were driving 11+ mph over the limit.

However, Tempe and Scottsdale still have red-light cameras. I have no issue with red-light cameras, so long as common sense is used when reviewing tickets. TFA:

Although most were still violations of state law, they were considered very close calls or were due to such reasons as vehicles stopping a short distance over the stop bar that did not pose a traffic hazard, vehicles moving out of the way of an emergency vehicle, plates that were unidentifiable and weather related issues.

Speeders going 11-over when the rest of traffic drives 8-over aren't a public safety risk; red-light runners coming perpendicular to broadside traffic and kids in crosswalks are.

Sounds like a sudden outbreak of common sense. Ticket those red-light runners. I paid my ticket for getting there after the yellow; fair and square.

Unfortunately, unlike Gmail, current users cannot send invitations to their friends (or other interested parties). Google Voice is currently available in the United States, with free domestic calling and SMS, as well as cheap international rates."

Time to take stock. Go home with some office supplies.
