  1. Re:Forgetting some things? on Thrust from Microwaves - The Relativity Drive · · Score: 1
    Here's the reason it can't be used for forward thrust:
    Shawyer has calculated that as soon as the thruster starts to move, it will use up energy stored in the cavity, draining energy faster than it can be replaced. So while the thrust of a motionless emdrive is high, the faster the engine moves, the more the thrust falls.


    It is best used for force applied without actual movement (ie. hovering). Though I wonder how useful that is since the real world has undulations which would starve the cavity of force as they were followed. I guess it depends on how fast or slow you climb or descend. Damn it! Maybe my flying car will show up finally!
  2. Re:Will anyone care? on HP Spying More Elaborate Than Reported · · Score: 4, Interesting

    If what you said were true, I'd be inclined to agree. The people involved have NOT been punished. The Chairwoman will keep her position until January at which point she will step down but KEEP HER DIRECTOR SEAT. The CEO Mr. Hurd, a director as well, was an informed and complicit participant in the decision as much as the Chairwoman. HE WILL BECOME CHAIRMAN. Another director resigned in protest of the investigation. His symbolic resignation intended to be an embarassing slight to the board and force them to reconsider their illegal actions was covered up and not reported to the SEC as required by law.

    So, the roundup on punishments:
    Chairwoman moves down one slot, keeps money, perks and most of her power.
    CEO moves up to chairman
    Director (read: good guy) who resigned out of sense of duty: still gone from boardroom
    Number of directors on the board, reduced

    What should happen? I'm not sure as I don't have all the facts and I don't claim to be a lawyer. As a layman, I would expect Chairwoman Dunn to lose her seat on the board and forfeit any unvested compensation. I would hope Mr Hurd would lose his position on the board as well. The board should bring back the resigned member. The fellow who was leaking info should be removed from the board and lose compensation same as Ms Dunn. HP and other companies need strong boards. HP once had a reputation for good governance. Let's hope that returns.

    BTW - I don't work for HP or really care too much about them. No emotions or money invested.

    With Apple there is always a cutoff for OS support. It usually lands on significant architecture inflections such as Macs having a G3, USB Macs, or in this case a 64bit x86 Mac. It is conceivable that in 3 years Apple could discontinue ongoing OS support for 32 bit systems. It would actually seem pretty reasonable if they were to go completely 64bit. The first round of Core Solo/Duo models are 32 bit chips. It might then be better to wait a month for 64 bit Core 2 Solo/Duo systems for performance and supportability concerns going forward.

    However, if you don't foresee keeping your Macbook for over 3 years, don't worry. It might affect resale value, but that's your call. There is always a brief timespan where it is best to wait for the coming rev release. The same thing happened to me back when MMX pentiums were released. I had an order for 12 systems into a local VAR. I spec'd MMX CPUs at 200Mhz I think. Anyway, the VAR knew nothing of MMX. I told him to stall the order for two weeks as the chips should be released and available by then. We both waited. I got MMX CPUs two weeks later for the same price. I then played the one or two MMX enabled games available for an hour and got bored. Still, I got something for nothing except patience.

    YMMV. Apple could do nothing for 6 months! I am waiting though. I really want a new Macbook. I just need to replace the stupid touchpad button with a two sider.

    Just curious how you are going to hook up those 48 SATA drives to your 6 8-port SATA hbas? Where are you going to find a $1000 chassis that fits 48 drives? In one MAINTAINABLE configuration? As far as I know (and could be wrong) SATA is not an external bus. The SATA cards you mentioned would have to run outside of the box to another unless you find that 48 drive chassis I mentioned. Even if you ran a long enough wire to get to the other box mounted above your standard opteron 1U box, there's a lot of slack that has to be on that connection unless you want to disconnect everything just to pull the server out of the rack for maintenance. There are limitations to the SATA cabling you're not taking into account. Also add a couple more power supplies on here for each of the boxes that hold you drives. Cooling is also an issue that tier 1 vendors model very seriously before they put together a kit. Most home baked kits have either dangerous hotspots that effect reliability or are overcooled which wastes money. You should also keep your drives mounted with dampening to avoid vibrations from each other which can cause early drive failure.

    There's more to this than simply buying parts. This appears to be another viable option in the storage arena for apps that need very large local storage. The problem with using it for NAS storage is that Solaris has historically been pretty slow compared to NetApp. ZFS could improve the score here with simplified administration if anyone actually understood how it worked.

    From an interview on Forbes.com with John Connors, CFO of Microsoft after the announcement that they were issuing a one-time dividend of 30 billion (yes with a B) dollars:

    John Connors: The first thing was to keep enough cash on hand to give us flexibility to manage things like a severe short-term economic dislocation or investment opportunities. We haven't publicly said how much cash that will be, but it's probably fair to assume that, after the upcoming distribution, we will still have around $25 billion to $40 billion on hand.

    and here's another quote from the same article:

    We have a relatively unique model, in that our business is not capital-intensive. What drove our approach is that Bill [Gates] and Steve [Ballmer] and the board are pretty conservative. We don't want to be in the position where we have to make decisions because of the balance sheet. And while we don't anticipate that we would ever have a year with expenses but no revenue, we'll probably keep at least one year of operating expenses and cost of goods sold in cash on hand--that's around $20 billion in cash and short-term investments.

    Now if you like you can also look at their SEC filings if you want to argue with people. AFTER the $30,000,000,000 dividend, they'll have AT LEAST $25-40 billion dollars. That means they have on hand $55-70 billion dollars cash or liquid assets. Your last statement that shareholders would have "no control" over this money is just dumb. Shareholders have final control over everything. That's why they have yearly votes.

If they don't sell enough services to the members, they can be disciplined.

    Now, why would banks/credit unions do that to their customers/members? Usually two reasons:
    • The CEO is looking to grow the company to show that he achieved some huge percentage of growth and deserves a big bonus or better job at a bigger bank. This is irregardless of whether the company is properly focused on long-term stability for the benefit of customers, employees and shareholders.
