Someday, some race from some star system will look back at the silly "unbreakable" light speed barrier the way we look back at the "unbreakable" sound barrier today. Hopefully it will be the human race that does this first - it would be.... unfortunate to meet up with an expansionist species (like the Europeans on North America, or Australia, or Hawaii) after they have conquered interstellar travel and colonization.
To trade a mutual fund, you place an order to buy/sell before market close. The fund is priced some time after market close based on how the fund's makeup changed that day. I have, had a 5+% price fluctuation hit me in the day I was buying/selling a fund a couple of times in the last few years. The frequency of this kind of volatility is much higher since HFT, and a disproportionate fraction of HFT takes place during the last few minutes before the market closes.
It may not affect the prices directly. However it might affect the prices indirectly, by influencing the decision making of others (especially other algorithms).
And this is the test that was being run - expect a new HFT algorithm to roll out shortly attempting to turn the information gathered to advantage of the gatherers, and several more by other players who weren't placing the orders but were watching and taking notes.
In the "bad old days," I could track an investment on a day to day basis without much worry of what has happened in the last 5 minutes. In other words, if I bought a mutual fund, it wouldn't go up, or down, by much more than a fraction of a percent between the time I placed the order and when it executed.
Since the advent of widespread HFT, even well diversified funds can fluctuate 5% per day, get unlucky on entry and exit and you've lost 2 years of typical gains - similarly, get lucky on entry and exit and you've got an extra 10% in your pocket. We've already got Las Vegas if we want to gamble, I'm looking for a little more predictability out of Wall Street, instead we are getting less and less.
If anything, it's a transfer from the other players in the market, not "printing" money, so how are they not concerned about it? Most market players aren't HFTs.
As long as it inflates share prices, it's just as effective as printing money. When they push it too hard and the bubble bursts, it's like burning money with H-bombs.
Not annihilating, sharing the wealth, especially sharing it to the industry from whence our lawmakers spring. And who do we look to to reform the laws and stem the flow of money to lawyers?
What could possibly go wrong? The cost/weight of high def video cameras and display screens isn't so bad, but the potential for failure is going to spook most pilots. They know that wires don't short out and make their windows go black...
On the other hand, a lot of aircraft could benefit from a low angle looking camera/screen so the pilot can see the runway clearly on approach.
Probably it's more practical to put the viewing systems in visors. If something goes wrong with the visor, you can raise it. You also would get the advantage of multiple cameras, multiple viewing angles, multi-spectral imaging (infrared and UV), etc, with a processor that cuts out any malfunctioning camera. Some such features are already available, but more limited than I envision. I can even imagine military applications where you put cameras on the wingtips, potentially giving pilots stereoscopic vision out to kilometers. That could be very handy for landing a plane on a carrier, or in a dogfight.
Sure, but what stewardess is going to sleep with you after seeing you in that getup?
Thanks for that, though I must admit that in 45 years of life, this is absolutely the only time I would ever have needed that, so I'm not too disappointed that my 6 years in engineering University (including every single course offered in the math department and a few from physics) never mentioned them.
Your right to swing your fist ends when your fist contacts my nose. (Or, in today's "enlightened" society, when I am in fear that you might hit me...)
A reasonable laser pointer has a beam divergence of ~0.0015 radians, or a spot size of roughly 2.25 micro-radians. 6.28 radians in a circle, roughly 40 square radians in a circle, so a laser spot is about 18 million times brighter than a regular spherically emitting (Edison style) light bulb.
So, take a 3mW green laser and point it at someone's eye, you're hitting them with the same light-power as a 50,000 Watt light bulb at the same distance, and worse still, the light is monochromatic and all visible.
If I went around with 200,000 BTU/hr propane torch and fired it off across the bar from people, I'd expect to be restrained - the laser is even more damaging to the retina... but some people think it's a toy.
But, you can put these technical videos on the evening news a couple of times a month to show just how boneheaded it is to think you can get away with this.
Waaay back in 1993 I got a laser and shined it on the wall of a building about 1/2 mile from my house, just to see if I could see the spot, play with collimating lenses, etc. Well, the people in that unit were home and saw the light, so they stepped out onto the balcony - it took me about 1/2 second to switch the laser off (and the 2.2mW red with a spot size of about 6' wasn't going to be hurting anyone anyway). mostly I shut it off because I didn't want them sighting back along the beam and calling the cops with my address.

Let's take it a step further and outlaw obesity... probably more expensive and deadly than tobacco, only problem is that obesity isn't a minority condition.
The morbidly obese should be arrested, confined and restricted to a 1500 calorie per day diet, for their own health and the reduction of our health insurance costs. Too severe? Well, then why don't we just ban them from employment as a first step?
It's not merely libel, it's fraud, possibly extortion, and of course, ridiculously stupid.
And, if you're seeking relief through the courts, good luck with the jurisdiction issues, response time, and general lack of connection to reality that is the justice system.
You could also forward the mail to the FBI, local law enforcement, and Help Me Howard at channel 7.
If your business is being harmed by the negative review, $500 is actually a good deal compared to waiting for any of those agencies to actually finish their coffee and get back to you.
I think the best way to sting them is in the payment process, pay with bad checks or on another tack, highly traceable instruments and pass the info along to law enforcement.

NYSE traded stocks are already as volatile day-to-day as penny stocks used to be 30 years ago.

There's that amazing opportunity argument, like the lottery or the "American Dream," it's an effective pacifier for the have-nots, up to a point...

"nobody with the power to do anything about it is particularly concerned with "fixing" the problem". They should be.

Long ago, the most famous photo of Linus had him holding a brown beer bottle.
I'd like to hear Linus' current thinking on beer, and it's relationship to coding.

Good engineer: $60-80/hr
Crappy lawyer: $300/hr
Good lawyer: OMG$/hr
If you're going to bring in the suits, you'd better have the wheelbarrows of cash ready - which Google and Apple both do.

I might be able to fly blindfolded, too, but it doesn't mean that I would accept that option willingly when holding 300 lives in my hands.

Like riding motorcycles without a helmet?

Zero Point energy, man. It's cool, huh?
No, I mention two options - one is the bad check, the other is a traceable instrument and coordination with law enforcement.
If the extortionists want to complain about the bad check, then they have to come forward with their true identity to get anything out of it.
I'm not sure what branch of law enforcement cares enough to try to track down extortionists that are possibly located in non-extradition countries.

There used to be abuse@fbi.gov - but that's been ignored for almost a decade now.

Looking at the distro, there are plenty of fart packages in there.
