Conventional missiles have been supersonic for oh, 60 years or so now.
Yeah. That's why we're talking about the new hypersonic missiles.
It would be like saying "My Nissan GT-R is faster than a Ferrari 360, so I'm sure I can win a Formula 1 race."
Major military powers have been fielding hypersonic air-to-air and surface-to-air missiles for decades too. That's why we're talking about the (relatively) new hypersonic ground attack missiles.
A missile that can handle the heat of hyper velocity can probably handle a laser hit.
No. You don't put thermal shielding on your whole aircraft. That's just a waste of mass, and does nothing but reduces your payload. You put thermal shielding on those areas that are likely to heat up. That means the laser merely has to target somewhere that is not likely to see much heat. Normally you want to target something structural, something carrying fuel, or something dealing with guidance. Since anything hypersonic is basically a giant fuel tank, anything that's not a leading edge would make a wonderful target.
It is also difficult to track and lock on to an object moving that fast.
It is absolutely trivial to track anything moving that fast. It lights up like a flare on infrared. It's going to be hot enough that even simply shortwave IR on a standard CCD camera would pick up the light it is emitting. As for tracking, the path is going to be nearly ballistic, and it's not like you have to lead the target when using a LASER. All that really matters is the angular rate, and the angular rate is going to be slow at any significant distance. If the angular rate is too high to track, then it's already too close in to be worth even trying anyway.
A hyper velocity missile with a little software to jink around may be able to evade the laser.
It's not the software that would allow it to jink, but the realities of physics. At the speeds it would be traveling, turning a few degrees would take a few miles. Any faster and you would have structural failure.

Speaking of libertarians. Where are all the property-is-everything, guns-and-freedom, company-defending people now? My opinion on the beta is, yes, it sucks. But do you guys really think you own this site?
No. They are owned by the site. They are the product, sold to ad agencies, and the site is the manufacturing facility. The Beta is a new manufacturing process line being constructed, and the complaints are product being rejected by quality control. If the issues are not resolved by the time the new line goes live, manufacturing volume will suffer, customers will not have anything to purchase, and profits will suffer.
there have been a ton of advances around storing hydrogen
No there haven't. You can store it as a cryogenic fluid, but no one really wants the general public to haul around a significant mass of fuel at 20K. You can store it as a compressed gas, but no one really wants the general public to haul around a significant mass of fuel at several hundred atmospheres. You can potentially store it as a solid using metallic hydrides, but there hasn't been any meaningful work in that area for decades.
When an AC calls everyone freeloaders, they're a troll. Discussion actually involves... a discussion. An AC firing off an inflammatory comment and then leaving, never to return, is not a discussion.
What proof do you have whether an AC returns or not? If you have any proof, they are not an AC.
There can be no discussion without continuity. Without continuity, you merely have a series of one-off rebuttals. Without some form of identifying symbol, there is no way for an AC to be actively involved in any discussion. It matters not if they are written by the same entity or not, because as you say, there is no proof one way or another.
IIS has been on a fairly steady decline since 2000. There was a spike beginning in 2006 that rapidly died off in 2009, following which IIS continued its slow downward decline. Nginx actually has a higher usage than IIS, and Apache is still around 50%. IIS is only the server of choice among inactive placeholder pages on disused hostnames.
Encoding was added to the VAAPI interface, but was never supported by Intel hardware. There's not much sense implementing a protocol when there's no hardware to interface with. You may be looking for the Intel Media SDK, which wasn't made publicly available until the middle of last year.

No. They don't. At all. Homeopathy "works" on the principle that after dilution of a solution dozens of times, until such point as there is statistically no solute left, the water has somehow retained some magical behavior from that solute, and behaves as medicine. That's right, all homeopathic remedies are nothing more than water. They're a complete scam, and there's no counter to that fact, at all, ever.
They may also have various inert chemicals such as thickeners or coloring for purposes of packaging.
They may also have various active chemicals that actually behave as medicine, or at least cause some physiological effect to make you think the product is doing something worthwhile, but they are claimed to be inactive, because the "active" content is nothing more than water.
But I would care about:
1. Someone else charging you for a copy.
If it were in public domain, anyone could distribute it, for whatever price they wanted. Assuming a knowledgeable buying public, it would be a race to the bottom, and games would be worth no more than a few cents of bandwidth and server maintenance.
Well it isn't going to be "slashed around", but laser weapons are always on. A pulsed laser has an enormous energy output (far far higher than 30kW), but it really doesn't have much in the way of energy output. You're not looking to ablate away a few micrometers on the surface of the target. You're not even looking to burn a hole through it. You're looking to slowly heat it up over several seconds until structural failure of some vital component, like a fuel tank or wing spar.
Despite the fact that after decades of wrangling, loggers and environment groups agreed on a peace deal last year that included a ban on logging in that forest.
Peace deal? You make it sound as if they were causing physical harm to each other.
Just like Einstein didn't make anything Newton discovered incorrect.
Of course he did. Newton's laws of motion are wrong, but they're still close enough for use in certain scales and applications. The small angle approximation is wrong, but it still lets you do some trig in your head. Truncating a series expansion after just a few orders is wrong, but that's often all you need.
Working at the lab late one night, he got doused with radiation while in the presence of a strong magnetic field, and from then on, found himself incredibly attractive to members of the opposite polarity.
Actually, you do. CNC just means computer numeric control. It doesn't necessarily mean an end mill, lathe, or other traditional machining tool. In many applications, you can robotically layer carbon fiber over your mold. For example, the Boeing 787.

Well... it depends on how high up over Kentucky that [s]air[/s]craft happens to be.
In an unrelated note, is there any way to do strikethrough text on slashdot?
Didnt they do something like that toward the end of Buckaroo Bansai?
Was that before they crashed their spacecraft through a cinder block wall lit up by a bunch of laser pointers?
Not the ones pulling tanker trailers.
Diesel trucks don't run too well on gasoline. The octane is much too high.

3D printed metal? Uh, how does that work?
The same way 3D printed plastic works, additive welding, either through traditional welding from a feed spool, or powder sintering.
So prepreg? Or is it filament winding?
