Do you worry that there is more or less an arms race with competitors like arvie.com, and the entire industry is basically just adding service fees on top the costs of booking a site?

Not sure there is a fair approach beyond a lottery. Parks could embrace demand, and auction the sites off, but that is trading one bias for another.

It does not look like your target market, but I imagine this would be ideal for pet/valuable tracking. Put it in a collar or bike seat and if your fido goes for a stroll and does not come back you can search much faster with an easy drive down the road. Same thing to help find a stolen bike.

If the transmitter could be inductively charged in a dog crate or where I park my bike -- it would be very convenient too. Ping time could be much slower, even once a minute would be plenty fast. Appears you could get 24 hours transmit and gps without too much trouble in a pretty small package.

It was sold to a (wonderful) museum, The Henry Ford (http://www.thehenryford.org/), which every geek should visit at least once.

As an artist walks through an art museum and can see the progression of ideas from antiquity to the present. As an engineer you can walk through the history of technology at The Henry Ford, from a black smithy to a tour of a modern assembly line and most all stops in between.

You would be hard pressed to think of a better home for this machine. 900k is a lot of money, but I am glad it will be in a great museum, rather than at a private collector's home.

I live in a Detroit suburb, a large number of the residents here are engineers, many for GM, Ford and Chrysler, but quite a few for Toyota, Hyundai and other foreign suppliers (like Bosch and Yazaki). I see many domestic, but almost as many imports here.

I think a lot of the stigma is gone, certainly there is considerable pressure for people to drive their employers vehicle to work, but at least in my (relatively upscale) neighborhood, I would feel no social pressure against, and I bet I would have a bunch of engineers come visit, if I dug up a 100k and put a Tesla in my driveway.

Objective qualifications are not the primary filter. The biggest advantages are from a higher level of networking, your fellow students are generally from a higher income bracket, have better connections, etc. Similarly the best paying firms tend to focus on the more prestigious universities as well.

All of this leads to a situation where wealthy parents have the education and means to ensure that their children have the advantages to give them a better chance of going the more selective universities, adding another level of systemic injustice based on wealth.

Not commenting directly on your assessment of the state of PoS systems, but how does a software vendor (not OS or sys admin) protect against targeted malware that is able to get access rights to your RAM space from scanning for well known track signatures?

I agree more can and should be done, but protecting against targeted malware by a sophisticated attacker is a very difficult problem. The amount of money at stake is large, so the resources expended by the attackers is also large.

Personally I believe that the current credit card system is broken and needs a significant change, but this is a very difficult process.

An mechanical engineer, physicist, and computer programmer are in a car driving down a steep mountain when the brakes fail. The careens around bends picking up speed until they finally reach the bottom and the car rolls to a stop.

The engineer hops out of the car and begins inspecting the brakes for the source of the failure. The physicist grabs a pad of paper and starts calculating the maximum angular momentum and friction coefficients.

The computer programmer looks at the car, then at the mountain and says, "let's push it up to the top and see if it happens again."

Education outcomes, not debt fueled enrollments:

http://www.brookings.edu/research/reports/2013/06/13-facts-h... (in particular check the graducation rates based on income quartile).

Access to health care:

Food is a harder thing to pin down. There is no doubt that americans of most any income level have access to sufficient calories, but trying to purchase healthy fresh fruits and vegetables takes up a significant portion of my monthly income (family of 5, a long distance from the bottom income levels), but I could buy huge quantities of bread and rice for much less :-)

Upper education, health care, healthy food? It is easy to ignore if you are not at the bottom, but all of these things are less available to a growing number of people.

I have a real issue with the current NSA practices and with much of the government surveillance attitude, that said this generally sounds like a case of doing it right.

I like that there was a court order for specific cell towers near the robberies, it would be better if order specifically requested the intersection of the towers or in someway restricted further use of the information to prevent long term and or continued use of collected data for unrelated cases, but I do not find this to be egregious.

This was a case of law enforcement using reasonable tools to do their job and a judge was in the loop -- I think the there should be a requirement to show probable cause, but a I think that a judge should be able to see that in this case there was probable cause to believe that anyone who had been at X number of the banks at the time of the robberies was a probable suspect and the collection of the data would be warranted.

My issue is when law enforcement (or other 3 letter agencies) collect (and retain) all of this data (and email, and license plates, and security cameras...) for non-specific uses. This is a significant infringement on our personal privacy and a threat to our democracy.

I have three children and they frequently will ask me question that either I never knew, or have long since forgotten. I take these times to demonstrate another lesson -- how to learn.

When I was a child it would end up with a trip to the encyclopedia (we were a Collier's family) and if that did not satisfy our needs, a visit to the library. A few times, we have had to visit the library, generally so my kids can check out a book or two on a specific interest, as the internet/wikipedia/kahn academy now have so much content there are few things an interested mind cannot learn.

I think it is very important for children to learn how to learn and how to admit when you don't know something.

Really?

Maybe I am just old and remember using manual typewriters, line printers, dot matrix. Now when I get amazingly crisp nearly instant typeset output from just about everything in seconds I am still amazed.
