My 2018 Mini Cooper may be much larger and heavier than the original, but trust me, it's definitely still "mini"

It would certainly be nice if they fixed the performance of shared folders. That would make it much more practical to run multiple VM's on a single machine. See http://mitchellh.com/comparing... for some interesting info. I tried this myself, and it's true -- read performance on shared folders is many times slower than virtual disks, making them fairly useless.

Wildly inaccurate. The typical spread (prior to decimalization) for actively traded issues was more like 6.25cents (a sixteenth), which was the difference between the bid and ask prices. A market-maker (or specialist) would typically kick back some of the spread to both market participants in the form of "price improvement", so the actual spread pocketed by the market-maker was probably more like 3-4cents.

For this, the market-maker assumed risk by committing capital to maintain a position in a security, and also was responsible for "maintaining an orderly market" in the securities in which it made markets. (In practice, NYSE specialists were much more accountable than NASDAQ market-makers).

In retrospect, this appears to have been a small price to pay.

For me, it was the Tom Swift books. But I agree with the others who are saying:
- keep it simple (Dune? Are you kidding?)
- the hero/heroine should be a kid
- some of the older Asimov etc. "juveniles" could be a problem, just because they are so out-of-date by now.

Have fun!

My thoughts exactly -- doesn't anybody read books any more?

I used to have a co. that sold budgeting software for commercial film production, and I can tell you from experience that if your prospective customers can use your software without paying for it, they will. (OK, not all of them, just most of them).
I ended up using hardware dongles, and while they were a big PITA for both me and my customers, the alternative would have been to simply give the software away.

Actually, it's not so much about the spread as it is about the size. The decimalization of the markets in 2001 had the effect of fragmenting liquidity, by allowing arbitragers to "ping" the market with orders with very little risk. (Google "SOES bandit" for more info).

Also, 25-cent spreads (a "quarter") had all but disappeared by that time, except for very thinly-traded issues. The average spread was a "steenth" (6.25 cents) back in those days, and in retrospect that wasn't so bad. It left enough room for both buying and selling broker to make a little money while giving the customer "price improvement" -- i.e., a better-than-quoted price -- esp. for large trades.

The SEC's rataionale for moving to decimal pricing was apparently to help the "little guy", but it missed the point that most "little guys" have their money invested with big mutual funds, etc. Decimalization actually hurt them (and their little-guy customers) by fragmenting liquidity to the point that it became very difficult to execute large orders without "price impact" (which is when arbitragers find out that a big fund is buying or selling and try to jump ahead).

At the time I was consulting with the 2nd largest "wholesale" broker on Nasdaq, and they shut down the business because they could not make money at sub-penny spreads. Fewer market-makers means less liquidity which leads to situations like the May "flash crash" where so-called "market-makers" run for cover by posting "stub quotes", rather than "maintaining an orderly market" as specialists on traditional exchanges are required to do.

Yes, specialists and market-makers made good money back in the old days, but for the most part, they earned it by risking their own capital. (And by having a vested interest in the overall health of the markets). When all is considered, it seems that "we" (as in society) may be paying a much higher price today.

The securities markets are open to all -- including "investors" (i.e., those who buy with a "long-term" horizon, whatever that is these days) and speculators. The speculators engage in what is called arbitrage -- finding discrepancies in the market and taking advantage of those discrepancies to make a profit.
It can be argued that the speculators serve a useful purpose by keeping the markets "efficient" -- i.e., making sure that prices don't get too out-of-whack.
To a large extent, this problem was caused in the late 90's when the SEC mandated that stock prices be quoted in pennies rather than the quaint eighths, sixteenths, etc. (of a dollar). This led to traders being able to game the system with minimal risk by "stepping in front" of published (and presumably real) quotes for a dollar (i.e., a penny times 100 shares, which is a "round-lot" order).
The idea of decimalization was that it would benefit the small investor, but in fact most small investors (i.e., you and me) invest through mutual funds or something similar, typically managed by an "institutional investor" (e.g., Fidelity). The narrowing of the bid-ask spread made it much more difficult for institutional investors to find large blocks of liquidity without "market impact" (what happens when other traders find out if there's a big buyer or seller in the market).
There are markets are designed for institutional investors and that don't exhibit this behavior -- one is a company called Liquidnet, which only allows institutional investors and specifically excludes the "sell-side" traders because of the problems mentioned above.
There is a lot more to it, and yes, the markets continue to get faster, with "co-location" being an important factor now (because the speed of light is "too slow", many traders locate their computers in the same data center as the exchanges to eliminate transmission delays). Some traders boast of microsecond and even nanosecond latencies, but for the most part they are cooking those numbers to make them look better than they really are.

In the past, I've dealt with these kinds of things by creating a virtual machine with required VPN, AV, etc. etc. and use the VM image to access the network.
