  1. Re:Futures Markets on BitCoin Gets a Futures Market · · Score: 1

    futures markets in general are quite useful because they help provide economic stability

    From the investors point of view, that usefulness is kinda dubious---it can create instability in the markets due to misinformation. For example, oil goes up in price, you expect airlines to suffer, so you short airlines. But suddenly, airlines are up due to profits from their oil hedging operation. Similarly, oil goes down, you expect airlines to do well due to cheaper flights, and they suddenly all file for bankruptcy protection.

    Futures/currency trading is just another buffer of complexity between "whatever the company does", and "you, the investor". It makes it harder to gage what's really happening with the company.

  2. Re:Why bother? on Photo Reveals UK Plan: "Assange To Be Arrested Under All Circumstances" · · Score: 1

    my guess ``someone'' assumes Assange saw or was exposed to very sensitive stuff that can really badly hurt few in power... something on the order of ``9/11 was planned by CIA, and here's the full undeniable proof, with names of those involved'', or something of that magnitude. Perhaps there's a huge secret that can be pieced together from all the crap Assenge/wikileaks got over the years, and someone just wants that out of the way. Assange himself may not have any idea what it is...

    keyword: occasional. I generally work 7 hours (10am-6pm, +lunch), no more. That's the "usual day". However, there were perhaps 3 days this year that I left work well after midnight to get stuff out by morning. And I've done that without being ``asked''.

    Now if I was asked to do that everyday, I'd find another place to work.

  5. Re:The NYSE shouldn't reverse trades. on Knight Trading Losses Attributed To Old, Dormant Software · · Score: 2

    What folks don't usually realize is that most stocks already have about 20 years worth of growth and prosperity priced into them. With GDP not expected to make great strides, it will be a miracle if anyone will be able to extract more than 2% real return out of their broad index funds. Similarly, no sane small-shop or pizzeria owner would be satisfied with 2-8% return... the folks selling hot dogs on the street get a higher return on their money... and yet the biggest and most profitable corporations are so overpriced that even when they make a killing (e.g. hershey corp had 63% return on equity last year, which is very typical of them), the investors get crap compared to their purchase price.

    It's also probably to cut ties with overpriced service providers (e.g. HP).

  7. Re:BigData != "standard databases" on How Big Data Became So Big · · Score: 1

    Depends on the scale. If you're talking on the scale of google, yes, relational is probably out of the question... but anything slightly smaller scale (e.g. hundreds of terabytes range), can be managed relatively well in Netezza or Greenplum, with standard SQL access.

  8. when you fill up a balloon, what are you doing? (imagine you keep temperature constant via some mechanism), what you're doing is confining air molecules inside the balloon---increasing information (you know where those molecules are [inside the balloon], you're lowering their entropy).

    again, keeping temperature constant, release some air out of the balloon, having it do some work. You've just converted that information (losing knowledge of where air molecules are---increasing entropy) into work.

    the trick about keeping temperature constant is that the net gain/loss of temperature evens out above. In other words, a filled balloon at say 20 degrees has more information than those same molecules outside the balloon also at 20 degrees. (same temperature means molecules have the same kinetic energy---yet the ones in the balloon can do more work than the ones outside the balloon).

    A friend of mine used to set screen resolution to minimum (like 320x240) in Quake2 and 3 when playing deathmatch---rationale: it's easier to see and aim at a large pixel than to see and aim at a player model from across the map (sped up railgun instagib thing).

    frankly, I'm not sure why NASDAQ didn't bust clearly erroneous trades made on day 1. That would've made investment banks unhappy, but then nasdaq wouldn't be in such a big mess itself... Most out of whack trades from ``Frash Crash'' got busted, why not trades-during-trading-system-crapping-out periods?

  11. Re:No offense, but that doesn't sound like a lot on How Intuit Manages 10 Million Lines of Code · · Score: 2

    Managing your own code vs managing 10m of code someone else wrote are very different. Even the most stupidly trivial functionality can take forever to figure out in someone else's code.

    There's also code densitity... I once single handedly `wrote' 250k lines of code in an evening... by writing a generator against Rational Rose files... Draw a box with a name and some attributes, and bam... you got a dozen files of about 10k total lines (ddl, store procs, database helpers, value objects, corba stubs/skeletons, list view gui, detail view gui, edit view guil, all that crap). I seriously doubt any significant portion of that intuit 10m code base is anything other than boilerplate code... but who knows... perhaps 2/3rds of the code base are setter/getter methods generated from some metadata :-D

  14. Re:Liability on Why Ultra-Efficient 4,000 mph Vacuum-Tube Trains Aren't Being Built · · Score: 1

    Not sure why something the size of an oil pipe-line wouldn't work... 3' diameter or something, where you lie down in a pod that zaps through the tube. With perhaps 2-seconds gap between pods. Perhaps with a switch that allows for more than one destination. That would be cheaper (e.g. maybe 100x more expensive than a similar-length oil-pipeline, but still "within imaginable range").

    Hmm... though 2 seconds between pods would mean you can only service ~40k people a day (how many does JFK service a day?). Though you could double that by halfving the distance between pods... perhaps have a nearly continuous stream of pods going 4kmh?

    This is spot on. You can't even be ``fired''---the worst folks can do is not extend your contract (just as bad for you, but technically, not ``fired''). I've also never seen consultants escorted out the door by security... yet I've seen that to TONS of employees on their pink-slip day. With corporations, its like that portal song, ``We do what we must because we can.''

  18. saving as many human lives possible on A Critical Examination of Bill Gates' Philanthropic Record · · Score: 3, Interesting

    Eh, nice try. Consider ``saving as many human lives possible'' being pretty much the only goal, and all starts to fall into place. It's not about making folks happy, or not leveraging, it's about getting the most saved lives for your moneh, using whatever means [if it means using your moneh to get more moneh, good, if it means using your politics to get others to go along with you, good, etc.].

    Heck, it's one of the few non-profits that does things by the numbers. Look around, see what you can do with your $$$ that saves the most lives: identify stuff like malaria, and HIV,... which one kills most folks? malaria. So HIV gets no attention, at least not while other things are much bigger killers.

    That they got high hopes for their apps business---get more folks onto Win8, more potential customers of their Win8 apps store. Heck, they probably expect to make most of their revenue from that app store going forward (e.g. all MS software will be sold that way, and once secure-boot and trusted computing makes headway, probably all Windows software will go that same route, with MS taking a small slice of every sale).

    Lets say employee, using corporate desktop, logs into their health provider's website and via SSL gets confidential health records about themselves.

    Your company is now evesdropping on this sensitive information provided by the health provider (who does not fall under "your company policies" and has no idea your company is illegaly impersonating the employee login).

    e.g. it's not a "my equipment, my rules" situation. You cannot impersonate folks on 3rd party networks. Within your realm do whatever you want, but you cannot login into a bank account pretending to be the employee (which is what you're doing when you're faking certificates).

    In other words, disallow SSL access if you're that concerned about security, but don't go around snooping on folks private communications.
