  1. Re:Might cause a re-thinking of the F-35 on Long-Wave Radar Can Take the Stealth From Stealth Technology · · Score: 1

    If the antenna is smaller than 10 wavelength, you lose angular resolution. It's not a show stopper, but it makes the bird much more likely to over/under-correct while tracking, which eats up energy for steering and your time of flight on the bird. This shortens your effective range and shrinks your no-escape bubble, to compensate you have to launch multiple missile at each target. The only way to survive on a modern battlefield is to "shoot and scoot", if you have to shoot twice, your shooting when you should be scooting.

    A fighter jockey is always going to want bullets to shoot even if he only shoots them on the range once a year to qualify, because that's just the way their brains are wired; just like all the Apollo and Soyuz space craft had to have windows.

    The real purpose of stealth isn't to be invisible, but is to avoid being visible enough to hit. The bird I worked on, the HAWK missile was a semi-active radar homing missile operating in the military portion of the x-band, 10GHzish and was 37 cm, or 14.5 inches in diameter which is about 10 wavelength in diameter which is the rule of thumb for getting enough angular resolution for to hit what your shooting at. By having to go long-wave any semi-active homer isn't going to be able to resolve the target clearly enough to really hit it, having missiles flying close misses to your aircraft is still freaky enough to make a pilots asshole tighten considerable just like you don't want a blind man throwing knives at your sound, which brings us to the other components of stealth which are not being where your expected to be and not doing what your expected to be doing.

    How was this even possible? Passwords should NEVER be something you can steal since they shouldn't actually be stored as clear text (or even encrypted, for that matter).

    Hasn't it been common practice, for at least a decade, to store the passwords as a salted hash (using a unique salt for each user)?

    You shouldn't be able to steal a password since the site shouldn't have it.

    The site doesn't have to have the creds to be able for them to be stolen, it only needs to acknowedge the creds are correct and your logged in.

    I don't think the point is that under-grad's will be self-educated by selecting modules ala cart, it's more likely that series of modules will be required. Now people often find themselves having to take a 16 week course that's required for their program because a critical topic that the course talks about for one week; now the student can take the modules that covers the specific learning objectives instead of a large course that's mostly wasted time.

    My profession requires Continuing Ed courses, the vast majority of times the courses are simply over-priced fluff seminars that are little more than a way to go to Florida durring the winter and play some golf while being able to write-off a tax deduction. Yet the only College in the state that teaches my profession has a 15 seat limit, I would love for there to be college level learning modules to augment OJT and continuing Ed.

    My understanding is all we know about a blackhole is their mass, charge and angular momentum, everything else is either implied or assumed. We know density is a measure of an amount of mass in a volume of space; we know the mass of a blackhole but the volume is unknown, time-space become undefined at the event horizon and something divided by undefined is undefined not infinite. It's just as likely that as the event horizon forms, the amount of time-space "inside" the event horizon increases due to time-space curvature and ergo the volume increased so the density could actually decrease.
