    The once a year part is annoying as well, since anything good you've done that wasn't last week has been pushed off the stack.

    Worse than that, anything good you've done that wasn't during a one week span of time five months ago has been pushed off the stack. There is usually a delay in large companies between creating an assessment and sharing it with an employee that lasts a few months.

    Oh, and during that few-month dead zone nothing counts. If you do something big during this time it will just be considered part of the baseline for the next review.

    What's the tracking distance of Phalanx?

    My only concern with CIWS is how far out it can track a ground-hugging hypersonic missile. You don't have a lot of time to engage it when you can't see it over the horizon. Even at 60 ft elevation on a ship, the horizon is only 8-9 miles away.

    That gives you, what, maybe 5-6 seconds from detection at the horizon to impact. You'd have to have your Vulcan firing 2 seconds after detection to hit it.

    If you only have two seconds to fire in order to score a hit, the missile only has two seconds to maneuver towards you in order to score a hit. I can't see how a sea-skimming hypersonic missile could hit a ship unless its position at time of impact were known with high accuracy.

  3. Re:hypersonic hypershmomic on Do Hypersonic Missiles Make Defense Systems Obsolete? · · Score: 1

    The ability of a hypersonic weapon to jink is going to be very limited. Honestly, it will be so limited that I have no idea how it would even hit a ship in the first place unless it were stationary, or the missile had a very high trajectory and powerful sensors so that it could acquire the ship 75 miles away. Of course, in the latter case the ship could also acquire the missile even further away and it would be in line-of-sight the whole time for a laser.

    A hypersonic missile fired at a ship designed to appear above the waves a second before impact will probably appear above the waves just to find no ships a second ahead of it.

    Agree that a hypersonic missile would work against a fixed target.

    Nukes are great at killing things, and then getting yourself killed. Their main purpose is to exterminate the entire human race and they don't work very well if used with any other goal in mind.

  6. Re:Exactly what I was thinking on Do Hypersonic Missiles Make Defense Systems Obsolete? · · Score: 2

    Agree on the anti-ship bit. In order to fire a conventional missile at a ship you only need to know its location within a few miles, and if you know its direction of travel you can have even less certainty. The missile is programmed to fly to a particular point and turn on its radar, then to travel along a course looking for something to destroy. If the missile spots a ship within a few miles to either side of its flight path then it turns towards it and attacks it. A conventional missile has no trouble turning because it is traveling at a somewhat slow speed (granted, faster than most aircraft).

    A hypersonic missile couldn't change course very quickly due to its high speed and likely small control surfaces (if they were big they'd rip right off when used). It might be hard to shoot down the missile if you spot it only seconds away, but that problem works just as well in reverse - if the missile spots you only a second or two away it will have a hard time steering towards you. Now, you could put a huge radar on the front and fly at high altitude to spot a ship 50 miles away and have more time to turn towards it, but that also means that the ship has more time to fire back.

    Against a fixed land target a hypersonic missile would be very effective - it would have no radio emissions, though it would no doubt be quite bright in IR. You'd need to spot them a long way off using power radar, which of course is vulnerable to attack.

    Apply your silly argument to electrical wiring and you'll see exactly how silly it is.

    If it weren't for the requirement for licensed electricians and the long precedent of company-sinking lawsuits when these laws are broken, you'd probably get electrocuted every time you touched a store shelf.

    At my workplace the telecom gear is all centrally managed, but with about as generic a configuration as you could imagine. Network credentials really only have a few levels of access - if they can connect to the VPN they can connect to ANYTHING. If you have physical access to a network port, then you can also connect to anything. In both cases the ID might not let you log into any particular resource, but the network will route arbitrary packets just about anywhere.

    Apparently the door card readers are an exception because the last time I needed to have one of those installed it cost a fortune to run security conduit (filled with pressurized gas with a sensor so that it would be very difficult to tamper with the cable run without being detected). Of course the door this protected was made out of wood and located in a building that was essentially unoccupied over the weekend (though you would need off-hours access (which is readily available but logged) unless you planned to enter during business hours and hide in a bathroom).

    All the arguments above are true - we could have ACLs on everything, VLANs, RBAC on servers, and all the other goodies. The problem is that maintaining all that stuff costs somebody time and as a result we end up with ACLs that get half populated before somebody just sets some really broad grant of permission.

    Pity - you missed one of the most annoying features of the new beta then. If you have a threaded view then you can collapse posts to headlines and also get the "3 hidden comments" link for completely suppressed posts, which really helps to give a thread context. Posts also have a parent link. All of this means that when I find a particularly interesting thread I can quickly expand all the posts and get more info (sure, that includes some junk, but it also includes really great comments that just haven't gotten modded up yet).

    All of that stuff is missing in the beta. I can filter the whole list down to +5 or whatever, but then I just see a few posts and no context at all. I can't pick one of those posts and start expanding filtered posts around it - at best I can copy some text out of it, unfilter the whole thing, and then search to figure out where in the mess it went.

    I agree with that, but going WAY back in the thread it was suggested that serfs weren't very happy, and they weren't very productive (both compared to modern workers). Both are true, but to establish a causal relationship you need to control for the impact of technology. Would a modern serf be less productive than a modern employee? Actually, even that isn't quite right because the argument is about workers being happy, not workers being bound to the cube, or whatever.

    True, and one way you could outsource is to just print a ton of money and fence it. I give you $100 in counterfeit bills, and you hand me $50 in real ones. You don't have to worry about making counterfeits, and I don't worry about how to get rid of it.

    The problem is that that press is a big expensive single point of failure. I can run a drug empire that involves lots of people cooking meth in their kitchens or whatever. If the cops bust one no big deal. On the other hand, if I had to smuggle some press that costs $10M and weighs 10 tons then if the cops grab it that puts me out of business. It sounds like these presses aren't just expensive, but they're monitored.

    Perhaps some set of circumstances allowed a counterfeiter to get their hands on one untraced, but that doesn't mean that it could be reproduced. I heard a story passed down in college about a jar of morphine that was discovered in a basement somewhere that predated the regulation of narcotics. It probably had a huge street value (commercially prepared, high purity, probably well-preserved). They ended up quietly destroying it so that they could avoid dealing with the mountain of paperwork and questions about how it got missed. However, if they sold it they might have made quite a bit of money. That doesn't mean that they could turn that into a business model - there wasn't some bottomless basement full of magical morphine jars that they could mine.

    Well, sure. But I can run Windows if all I want is an operating system. The benefits of FOSS go beyond whether it does the job.

    You can mount a cloud service storage on your system and use libreoffice if your issue is that you want the data available and stored in the cloud.

    There aren't exactly a lot of great cloud storage services that are FOSS even if that is the only part that you want to solve. I don't really see an FOSS alternative to something like Google Drive or Dropbox.

    You can install libreoffice on any desktop with linux or windows on, which probably covers you for all your needs, there's no more need for it to be a browser app any more than the browser needs to be runnable under a browser.

    Libreoffice requires X11 or Windows or OSX. My phone runs none of these, and neither does my tablet. My laptop definitely runs Linux, but I'm not actually sure if it even runs X11 (certainly it doesn't support installing libreoffice or connections from random X11 clients).

    Also, libreoffice does not support simultaneous editing across multiple clients, and even if it did I'm not aware of any cloud services which do (including non-FOSS options).
