Comment Best fix for poverty is removing regulation (Score 1) 1

One of the worst aspects of the regulatory state is how it gets in the way of people helping themselves. Occupational licensing, state-sponsored cartels like taxis, land zoning, regulations which prevent people planting vegetable gardens, all these things hit the self-supporting the most. Minimum wage laws hurt the unskilled by cutting back the opportunity to learn skills from entry level jobs. Too many places even make it illegal to feed the poor without restaurant-level food prep, or for groceries to give away food on its sell-by date, or fruit and veggies which are too ugly for commercial sale.

US local, state, and federal governments spend $7-8 trillion every year, which is around $50,000 for every household in this country. It's amazing that people have anything left for themselves, and since income taxes don't come close to matching this, it must come from sales taxes (10%), property taxes, business taxes (35%, I think, which is just passed on to consumers), and all the other taxes that are hidden away and people aren't aware of. This is an incredible drag on the economy -- 40% of GDP. Estimates are that somewhere around 15% of the work force get their pay from taxpayers -- whether directly (employees, military) or indirectly (military and other contractors).

Certainly a lot of this would be spent anyway (roads, schools), but competition would make it cheaper, better, and more innovative.

If welfare were cut way back to the essentials of people who cannot take care of themselves, if unemployment insurance were obtained privately like car and home insurance and related directly to work record, if health care were privately obtained and insurance was strictly for catastrophes, and if the poor and unskilled could help themselves by cutting hair for friends and neighbors without six months or a year of full time schooling, if neighbors could baby sit for neighbors without government regulators setting standards that parents are better able to judge -- if, if if the government would just stop making it so hard for people to help themselves --- the need for government welfare would drop like a rock. /rant

Submission + - Bash running natively on Windows? (theregister.co.uk)

Comment Re:timestamps (Score 1) 228

This problem has been solved in TOF laser range finders, like the hand held ones used on golf courses. An expander chip takes the incoming analog signal and stretches it out a million times with considerable precision. The signal can then be analyzed by standard low cost and low power processors.

The challenge here is that instead of a reflecting laser, you have the call/process/response in the equation. That process time will be orders of magnitude larger than the signal traversal. So, you'd have to have very accurate and standard processing times.

Comment timestamps (Score 2) 228

Solution:

(Assuming the key/car are using private/public key pairs)

You'd have to put a reasonably accurate clock in the key, and then have it encrypt and send timestamps to the vehicle using a sequence of rapidly fired request messages followed by response messages.

The car could then decrypt the messages and compare the timestamps from the sequence of messages measuring the distance between the key and the car. The clock in the key would have to have similar accuracy to a laser ranger finder.

The actual protocol would be a bit more complicated in the details, but the basics outlined above are what is needed.
