They implemented filtering on the evil bit.

Except that Boeing asked the FAA for a Special Condition to allow just such an interconnection.

This is true. But then it was only a few weeks in my high school calculus class to get from infintesimals to full blown differentials and integrals. And this is what we credit to Leibniz in the 17th century. So yes, there's more to calculus than that. But from Leibniz to now took 400 years. Archimedes did sugest the idea of infintesimals. So it looks like that idea sat in the dustbin of learning for 2000 years before Leibniz picked it up again.

As I understand it, it's a 'feature' of the ADA legislation. Usually, a plaintiff needs to prove damages and the settlement will be based upon that amount. But if the damage consists of some disabled person not being able to buy a greasy hamburger at some shitty restaurant with no handicapped parking, what are the damages?

The solution is to continue to allow such suits. But to have anything awarded over actual damages be required to be placed into a compliance escrow fund. Where, once the business is sued a few times (or they get their ass in gear and pitch in some funds voluntarily) it can be used to fix the acessibility problems.

After all, this should be the object of the law: To improve access for the disabled. Not to squeeze businesses for an amount just small enough so they'll pay instead of fixing the problem.

... is based (among other things) on the supply of assets available to trade. So when the market is high, that means many investors value their held assets and don't make them available to trade. This reduces the supply and increases the value/price of the remaining assets still 'in the market'. There may be some other mechanisms at work that are artificially sopping up liquidity, like HFT.

If everyone put their portfolios up for sale, prices would drop fast and far.

Too expensive and difficult.

Simply engineer a heat shield for the warhead that is ablative and outgasses enough to provide a protective layer around the object. The advantage of this over a mirror is that the laser's heat is carried away by the emitted gas.

I haven't been involved with the PTC system. But from wht I've heard in the news, my guess is that this is intended to be far more than just a maximum speed governor system. Seeing as how Congress was involved in mandating it, there are probably requirements in the implementing law to prevent almost every kind of track switch, train conflict, temporary track restriction and conflicting traffic accident you can imagine. So the sensors and communications systems needed to support the requirements are quite complex. And the code is very complex.

This isn't a Gogle car, where private enterprise took the initiative and developed something that just works. This is system and software requirements written by a legislative body.

My car is so old that any reference to Bluetooth could only mean the Danish king.

You are probably living under an approach or departure path. In which case aircraft won't be flying supersonic. The Concorde needed several hundred miles to decelerate below Mach 1 and usually reached subsonic speeds before entering an ATC area (a flight path).

Aircraft are increasingly moving away from point to point established routes. These date from the days when cross country navigation was done between radio beacons with direction finding receivers. Now, its based on individually planned routes which can be spread out, reducing the impact on any one point on the ground (and spacing flights apart for safety as well).

I live with them every day. I'm along the approach path to SeaTac and aircraft pass overhead at about 6000 feet numerous times a day. No problem.

What gets exciting is that this is also (sometimes) the approach path to either Boeing Field or Paine Field. And occasionally a test flight comes over at 1500 to 2000 feet if they are in trouble. Gear down 15 miles from the airport is usually trouble as in "We f*cked up the hydaulics installation again! No flaps!"

It's no worse than thunder. Wild animals have been living with that for millions of years.

... a 'Trigger Warning' tag for all the sperglords.

It's pretty well accepted that Archimedes developed calculus and wrote about it. And then his manuscript was erased by Christians so the parchment could be used for a bible.

History is full of Greek, Arab and other discoveries and sharing of discoveries between cultures interspersed with religious nut-jobs stepping in and messing things up, either intentionally or through ignorance.

Um, there's a lot of air being heated as well. In fact, that's the point.

More like 54 * 10^6 joules/sec

Go back and crank in that 10^3 factor. It's not that quiet. But then again, since our ears and perception are logarithmic, it's not that bad compared to other sounds.

It's also a function of altitude. If you can keep supersonic aircraft at or above 60,000 feet (and there are reasons other than noise for doing so), the shock wave energy is spread out over a greater area and attenuated.

But the detectability of supersonic aircraft is. So this is probably the customer at whom this technology is targeted.
