  1. Re:where is the random? on High-Frequency Traders Use 50-Year-Old Wireless Tech · · Score: 1

    I think the situation people mostly worry about with market making is where Alice submits an offer to sell for at least $1.00 and Bob submits an offer to buy for no more than $1.02. There's $0.02 of surplus here, and we would expect it to get somehow split between Alice and Bob. When we add in Martin (market maker) to the scene, people worry that he would accept both Alice's and Bob's offers and pocket some of that $0.02 surplus for himself. If Alice and Bob both put in their orders at the same time, then Martin is obviously left out, but it's never really simultaneous. This leaves a time window when Martin could potentially insert his own pair of buy and sell orders. If it's a rather slow market, and Bob's orders appears a few days after Alice's, it's reasonably clear what service Martin is providing (Alice can quickly and reliably offload this thing she no longer wants, and the item is readily available for Bob to buy when he finally wants it).

    On the other hand, if the market isn't so slow, and Martin is doing HFT, it's less clear what Alice and Bob gain from him. If he's able to take a position and close it in a matter of seconds, people start to wonder just how much better off Alice is from having been able to finish her sale seconds earlier. It looks like we've got diminishing returns as Martin's holding periods shorten. His claim that he's providing liquidity looks dubious in a market that has to already be pretty liquid to support the activity people see from him, so they suspect they're being hoodwinked. Modern technology enables really large scale market making, so Martin's got a lot of money flowing in, which makes people even more suspicious.

    Personally, as a rather small-time investor, I don't really fret about this. Even if it is the case that I am getting some of what would otherwise be my money skimmed off by someone claiming to have provided liquidity that was already present, I don't make enough trades for that potential loss to matter much. I worry more about whether this is a good (for society) use of the math/engineering talent we produce.

  6. Re:Dangerous move on Regulators Investigating Unpaid Internships · · Score: 1

    Seems to me that for an internship to be educational to the intern, she needs to be doing something useful.

    IIRC, a SCOTUS case dealt with a trainee program run by a railroad company where prospective rail workers would essentially do simulated work, supervised by actual rail workers. SCOTUS ruled that their arrangement did not require pay, and listed the fact that it was simulated, not real, work as a necessary condition.

  7. Re:If your working, then yea, that should be paid. on Regulators Investigating Unpaid Internships · · Score: 1

    The question is whether they really want to be unpaid or if unpaid work is just something they have to bend over and take in order to have a career. If the system effectively requires those new to the field to work without pay for a time, it is certainly not for the new workers' benefit, yet those defending the unpaid work keep on claiming that it is.

    The fact is the current Soyuz launch record without fatalities is quite definitely and literally significantly better.

    Except the "current streak" metric is close to meaningless. It depends too much on when the sample is taken. Even with two agencies of equal success rates, it is very unlikely for them to have equally long success streaks at an arbitrary point in time. This is the same reason why "current uptime" is not a good metric for system stability. Run the numbers for MTTF, and then we have something to talk about.

    Good programmers should be able to pass a competency test for any employer. If they pass that test, they should be able to seek the job, degree or not.

    It does not define "authorized access". However, if without engaging in any spoofing or fraudulent behavior, you request access and are granted access, there is no way that any rational human being could hold that you have "knowledge that the access is unauthorized".
    You might also go with the rule that simply being granted access is not a reasonable basis to assume you're authorized. Unless the law specifies this, all we can do is speculate.

    The router is not sentient. It has no ability to judge, and despite the fact that it may invite some people in does not mean it is entitled to do so or that they are entitled to enter.
    Sentient or not it's making decisions and letting people in (and it's also capable of denying access). We don't need a law saying whether unauthorized access is allowed -- we already have that. What's needed is an explicit rule about what constitutes authorization, so there won't be this kind of questioning.
