A heuristic like that would not allow Knight to function. Knight is an electronic market-maker (one of the biggest) and is probably making markets in thousands of symbols and likely updates those quotes several times a second. Their normal quoting rate is on the order of millions of messages/minute and in volatile times may spike 10x or more and still be within 'normal' limits.
Please stop.
All semi-automatic rifles with detachable magazines are functionally identical.
The suspect had a rifle, shotgun and handgud. that is 'loaded up'?
Since when does 'requires federal background check' == 'nearly unregulated'?
This is rather debatable. I would rather have a restored piano from an established manufacturer than a shiny new one from an untested brand at the same price.
I'll take the other side of that bet.

Their explanation of the venue choice was that the other federal courts were choked with drug-related cases and going to East Texas was a way to get a speedier trial.
Compare this from the article:
"[T]he standard geometry book for Fairfax County, which is
used in schools around the country, tries to explain what
a mathematical point is by analogy to pixels on TV
screens, which are not in fact point-like."
"[T]he books were so lousy. They were false. They were
hurried. They would try to be rigorous, but they would use
examples (like automobiles in the street for "sets") which
were almost OK, but in which there were always some
subtleties."
"The definitions weren't accurate. Everything was a little
bit ambiguous -- they weren't smart enough to understand
what was meant by "rigor." They were faking it. They were
teaching something they didn't understand, and which was,
in fact, useless, at that time, for the child."There IS a negative feedback mechanism. Occupancy rates. Once people stop paying the asking rates for listings the prices will fall. It is called "what the market will bear".
And the number 3 is different from your fingers being number now than they were before.
Not sure about 'familiar' though.

> After the calculaton of the FB IPO Cross was completed, but before printing the opening trade, additional order modifications were received by the system, changing the auction order book. As designed, the system recalculated the IPO auction to factor in the new book state. Again, changes were received before the IPO cross could print the opening trade, which resulted in additional re-calculations. This condition persisted, resulting in further delay of the opening print.

Robust? yes. Adaptive? yes. Complex? not really. Computer vision, road/object/hazard detection and avoidance and the like much much harder problems to solve.
I _was_ a proficient excel user once upon a time but now I feel like I'm trying to cook in my kitchen after some "organization expert" came in and moved all my stuff.
IMO, life is too short to have to re-learn stuff you already know.
What is your definition of "ETN"? The only definition I know is "Exchange Traded Note" which doesn't make sense here. Do you mean "ECN"(Electronic Communications Network)?
Yes. huge problems. 20 years ago (1992) stocks were traded in 1/8ths or 1/4s (minimum spreads of (12.5 or 25 cents) often more than one tick wide. By the turn of the century stocks had all been decimalized (traded in pennies) but spreads were still wide.
This article: page 25 of this paper[1] shows the average stock spread of S&P500 stocks being squished from 8cents in 1997 to less than 2cents in 2010.

The short summary is no one can come up with something better than price-time priority for matching orders.
Or the evidence of a differing opinion on what amount of complexity is necessary.
I have been using UNIX-type operating systems almost exclusively for the whole of my professional life so have zero appreciation for the troubles people have when approaching UNIX tools from a Windows (or whatever) mindset.
Git (and the whole toolchain and OS for that matter) is much more about DWIS than DWIM and that does not click for a lot of people.

That is: if you short a stock (leaving aside that you cannot short non-public stock) and it continues to go up you will need to continue adding money to your account to cover your accumulating losses. If it goes up high enough and you don't have enough collateral your position is closed and you are broke.
It is not enough just to identify a bubble you also have to call the top with a reasonably degree of accuracy.
Early investors in startups cash out during later funding rounds or acquisitions.
QED.
The contractor who underbid. If Roger's submits a bid for $1m to deliver 50k widgets he shouldn't be able to come back after the fact and demand $4m to complete the project because he underestimated his costs.
Not even close. Insurance will reimburse you for the loss (minus a deductable).
