    They'll point out scornfully that you now have TWO missing links where previously you jst had the one.

    Just the one? I counted at least a dozen.

    Don't worry, Biblical literalists - the creationists are all positive that every one of those skulls is either an ape or a man, and none is an ape-man. They seem to have a little trouble agreeing on which is which, but that's surely not relevant to the problem.

  2. Re:"partially reusable rocket" on SpaceX's Falcon 1 Destroyed During Maiden Voyage · · Score: 1

    If anything, the shuttle program has proven that reusiable spacecraft are a bad idea. They're not cost effective.

    Just how reusable is the shuttle? The expendable external tank costs about $60 million to build from scratch; refueling a solid rocket booster (particularly one that's been dumped in salt water) is about as hard as building one from scratch, and the orbiter isn't ready to fly again until at least the thermal protection and engines have been pretty heavily rebuilt.

    When most people talk about reusable rockets, they're imagining something like the DC-X or SpaceShip One: land it, do an inspection, refuel it and launch it again the next day. Even the Falcon rockets will never quite be in that class, since their landing procedure includes being fished out of the ocean. Their reusability is very much an experiment, too, from what I've read - SpaceX has said that they're pricing launches high enough to make a profit without reusing anything, and if it turns out that they can successfully use the same lower stage for several launches, that's just more profit for now and more room to lower their prices later.

    Maybe like you say, resusing the lower stage would work out ok.

    Reusable launch vehicle naysayers used to believe that making any rocket conveniently reusable isn't practical. DC-X disproved that for low performance rockets, but maybe they're right and it's too hard to make a high performance rocket conveniently reusable with current materials technology. Well, it used to be too hard to make even expendable rockets with past materials technology, and they got around it by stacking lower performance rockets on top of each other. I hope the same trick will work again.

    You have to admit, subjecting these claims to the marketplace should prove whether or not there's anything to them. The number of people willing to believe their houses are warm when they are cold is probably a lot smaller than the number of people willing to believe they've been cured by quack medicine.

    Don't these cold fusion devices supposedly require electrical input to initiate fusion? If you run current through a resistor, it will generate heat, and how many people hook their space heaters up to calorimeters and multimeters to see if power out exceeds power in?

    Elon Musk has said he can take up to three ruined launches before having to reconsider his financial support... but if he had a budget the size of, say, the suborbital X-33 project that never got out of the hangar, he'd be able to afford a couple hundred more launch attempts first.

  5. Re:"partially reusable rocket" on SpaceX's Falcon 1 Destroyed During Maiden Voyage · · Score: 5, Interesting

    Actually it is the "partially" in the sense that the first stage should parachute and be reused, but the second stage is space junk.

    This is the right way to do it, too. Lower stages are larger, so you can save more money making them reusable. They're less important for overall rocket performance, so when making them reusable reduces their performance it's not so bad. They don't reach orbital speeds, so you can recover them without reentry shields or even without flyback capability. If we're going to move toward reusable rockets (which could be a very good idea) at a gradual pace (which the Shuttle program has proved is a good idea), the way to start is from the bottom up.

    Just as bizarre was that they had a payload on their first launch attempt.

  7. Mod parent up on Highly Critical Hole Found in IE · · Score: 1

    Systrace (assuming you're talking about this systrace; the link you gave me was broken) looks very impressive. I'd worry that there may be applications for which slowing double checking every system call would be a real performance hit, but the worst-case example the systrace developers benchmarked was a find command where running through ~60,000 files took 42 seconds instead of 30, and a web browser doesn't need to access ten thousand files per second.

    I hope systrace gets taken up by more Unixes and Linux distributions soon, though; any sort of capability-reduction policy is best written by the programmers of the software it applies to, but that won't happen until systrace is as common as chmod. Remember my example of letting an application create a new subuser to run as? It wouldn't be hard for any system administrator to make that possible, but because it's not a standard Unix feature there aren't any programs written to utilize it.

    This just goes to show that if you give MS enough time, they'll eventually be able to reinvent UNIX-like security.

    Oh, really? What user is your copy of Firefox running as right now?

    I thought so.

    Although UNIX kernels certainly make it possible for users to run processes as other user ids, I've never seen a *nix installation make it easy, much less make it the default. Even the foundations aren't there - imagine what it could do for security if process ID 5860 running as user john automatically had the ability to create subuser john-5860 and run child processes as that unprivileged subuser, with read/write access to only a directory created for that subuser.

    It know it's fun to gloat that Unix security was better than Windows security years ago, but I'd be happier if Unix security stayed better than Windows security months from now.

    Hell, can they even look at it and still be able to contribute to SAMBA?

    Of course they can. I can see why people are paranoid about being "contaminated" by other's intellectual property (wasn't clean room reverse engineering how Compaq successfully defended itself from IBM's lawsuits?), but legally copyright is copyright. Reporters are still allowed to read other newspapers, authors are still allowed to read other books, musicians are still allowed to listen to other songs, screenwriters are still allowed to watch other movies, and yes, programmers are still allowed to read other source code.

  10. Baldur's Gate (and BG2, and BG2:ToB) on Two-Player Games for Mixed Skill Level Players? · · Score: 1

    You start with one character each (by having one of you either generate a second character or control the girl Imoen who joins you soon after the game starts), at a low enough level that the gameplay is simple to learn, and it only gets more complex gradually. The game can be paused at any time and new orders can be given while it's paused, so if your girlfriend needs to take her time she can.

    It's all cooperative play; you're not competing with her. This means that you spend a lot of time talking while you play and that many of your game actions will be saving each other's characters from mortal peril. It's a fun bonding experience.

    When you pick up more characters along the way, she can take half of your party of 6 to be fair, or control just 1 or 2 players if she doesn't want to do as much micromanagement as you.

    There's a long, interesting story line that gets continued in the sequel games.

    One pitfall: in BG2 there's a potential love story involving the main character, and (assuming you're the male main character, like I was) the love interest possibilities aren't good. Do you make your girlfriend think you like ditzes or bitches?

    The only other problem: these games take dozens of hours to complete. If your girlfriend is up for playing dozens of hours of D&D with you (can mine have a round of applause?) that's fantastic, but you may be looking for something more casual.

    Exactly. And the request was denied. That should be that.

    The 4th Ammendment protects against unreasonable search not all unwarranted searches.

    And what makes a search reasonable or unreasonable? Here's a hint: if a private citizen would be legally allowed to perform the same search, it is reasonable. If a private party would be charged with a felony, as you or I would be if we obtained Google search data by force or subterfuge, then the search is unreasonable.

    The issue in this case is that the information request in question isn't really a search as it's not being used in a criminal case.

    There is no dictionary, legal or otherwise, that says "search" doesn't mean to search unless it's to provide evidence for a criminal case. It is true that courts have refused to admit evidence obtained by illegal searches as a way of discouraging them, but that doesn't mean the search was legal until a prosecutor tried to use the evidence. That court rule also may not mean as much today as it used to, since an accused criminal's right to see a court and see the evidence against him is under attack as well from this same administration.
