Are you trying to reinvent already outdated ETCS level 2?
I'm not inventing anything.
And why would it be outdated if it works, and we (US) aren't using it.

THIS MAKES SO MUCH SENSE. I always thought I was going crazy, thinking my increasingly "old" phone seemed slow. This is really irritating and disingenuous on Apple's behalf - as said above, they should at least add a switch.
Keep in mind this is relatively new. The press seems to be spinning it as an "ah ha, old phones really are getting slower!" Well, yes, now. I mean as of 10.2.1, so a year ago, but people have been thinking their phones were getting slower since smartphones became a thing.
Likewise with old computers.
And as someone else commented, "apple will never add a MAKE MY PHONE UNSTABLE switch."
> simply integrating speed over time
This probably runs into issues with accumulated error, especially if the error in speed measurement has a serial correlation.
That’s what sensor fusion is for.
That said, inertial nav can take a plane across the country without correction and get within sight of the target.
I think integrating actual speed while on rails would be vastly more accurate.
And really, it just need to augment gps.
That this is a problem is just ridiculous. It's on freaking rails! There is absolutely no excuse for this. GPS, Inertial Nav, simply integrating speed over time, it should be absolutely dead simple to calculate exactly where the train is at all times.
The article mentioned crap like differential GPS. Completely unnecessary. You don't need to be that accurate, I mean good grief, +/- 100 feet would be just fine for dealing with such gross overspeed detection.
I can't believe this is actually a problem. Pure politics/bureaucracy. It's certainly not a technical problem.

An informative series from pbs narrated by Jeff goldblum on YouTube: search for "dna episode 1 of 5 the secret of life"
It's a great high level overview of dna sequencing from the discovery of its shape through the completion of the human genome project in 2000.
I'm having trouble pasting a link, maybe someone could help me out.
The downvotes seem weird to me. Maybe it felt off topic?
Dr. Francis S. Collins is in several of the videos, and the third video is all about this particular controversy of dangerous experiments at the dawn of genetic engineering(for example one guy wanted to splice a cancer causing gene in e. coli bacterium).
It seemed relevant to me. It is what the article is talking about afterall.

>"Bonus points if you give it a name involving patriotism, freedom, economic or personal health, or a backromym that spells out the same."
Indeed, and this "cognitive dissonance" technique is so widespread now that you can generally invert the message to find out the actual intention of the legislation is. Examples:
If you are cutting taxes for the wealthy donor class say it is bill to "help the middle class and the poor."
If you want to take health care away from people say "it is a bill that will help the American people."
If you want to empower a monopoly just state that "this is a bill designed to foster competition."
"Patient protection and affordable care act"
"Patriot act"
All "right to work" laws

Does this mean you think all viewers are democrats (or even most) and that republicans are the enemy?
