Comment Re:There is nothing special about programming (Score 2) 767

half of Slashdot taught themselves to program when they were between the ages of 8-13

And that is exactly the kind of mind it takes to program. The good and bad programmers I've known divide fairly equivalently to those that taught themselves before high school and those who wrote their first code in CS 101.

if it were a zero sum game they would show a profit of zero at the end of the day

They do, for a certain value of "they". My only claim is "they" does not include buy-and-hold investors, the supposed virtuous everyday people that are the poster children for all this hand-wringing. "They" does include all the slightly-less-high-frequency traders, which I suspect are the drivers of this kind of agitation for reform.

Comment Re:Linking to Wikipedia to explain math (Score 1) 102

The historical dead paper encyclopedia wouldn't even have entries on these kinds of things. It is true wikipedia's math articles are written at a graduate or higher level, though. Personally, my response was to stop settling for less than the real deal and become a math grad student - one course at a time (taking my third now).

The fear about HFT seems to boil down to "things are happening that didn't used to happen before, must be bad." The algos are playing a high-risk zero-sum game, but only for the participants that are trading at the same timescale. For the classical buy-and-hold investor, its inconsequential. In the unlikely event a flash crash would occur and not get rolled back, it doesn't mean stock value has been "destroyed". It would be a tremendous windfall for fundamentals investors, who would buy it up to a fair value. In other words the HFT algos would lose the zero-sum game to players on a longer timescale. The reverse, a flash spike benefiting HFT at the expense of long term, wouldn't occur in practice. Traders would wait the extra 5 minutes to execute, like a tortoise playing a waiting game with a gnat.

The Silmarillion as a whole is not a story per-se given the vast spans of time and overwhelming cast of characters, but there are three major story arcs in it each with enough unity of time/place/character to receive a similar film treatment as the Lord of the Rings: The Children of Hurin, Beren and Luthien, and the Fall of Gondolin.
