Supersonic/Hypersonic wind tunnels are tremendously expensive and power hungry. There's pretty much no way to hide them. Yeah, there might be small scale versions out there (say the hypersonic helium gas guns etc...) but we're talking really small scale. This kind of testing is why NASA was given/assigned an SR-71; they could use the drone attachment points to carry tests and essentially use the atmosphere as a high super-sonic wind tunnel. Look at the pictures of the NASA SR-71 carrying the linear aerospike engine during testing.
Well, the other bit to consider is that when you're testing scale models in a wind tunnel, depending on what you're testing you also need to scale the wind/air conditions to achieve accurate results. Often this means scaling up the airspeed and/or air pressure as you scale down the object being tested.
Let's say I'm testing out a new design for an airliner wing. At full scale, the air flowing over it will exert a certain amount of force per area (PSI or Newtons/m^2, take your pick). Now, since it's not practical to put a full sized airliner wing into a wind tunnel, I build a 1/4 scale model, and put that in the wind tunnel. Here's the rub: if I ran the air over my 1/4 scale model at the same conditions as I were to test the full sized wing, I would be applying 1/16th the scale force. To make up for the difference, I need to either scale up the airspeed, the air pressure, or both. There are also a whole host of other weird effects that need to be taken into account.
Anyhow, it's not just that this thing is designed to test a vehicle/weapon capable of operating at 27,000mph, but rather that it can provide realistic conditions to a scale model of the craft under test.
This idea has some merit but you're always going to have people who for one reason or another can't go at the last minute and the ticket shouldn't have to be burnt just because of that.
At the same time you also allow full refunds until, say, 8 hours before the show. if someone else wants to pick up a last minute/rush ticket, they can buy it from the band/venue instead.
The incident in question did not occur during an engine firing. Rather they were performing a "LOX drop" test which basically involves pumping LOX through the engine and checking for leaks. Something went wrong in this process, causing the damage. Until the investigation is completed, there's no way to know whether it was an issue with the engine, the test rig, or the setup. It might be that a tech just dind't tighten something adequately, or a filler hose leaked or whatever. SpaceX won't know until they complete their investigation, and we may never know.
To quote Adam Savage of Mythbusters fame "LOX makes anything flammable. LOX makes something flammable into a high explosive." So even if they just had a sufficiently large leak, and the LOX leaked onto/into asphalt or similar, all it takes is a spark to cause that asphalt to detonate like a bunch of dynamite.
Tech stocks? Sure, but there are actually a lot of traditional stocks that actually pay dividends. Banks, and the traditional industrial set come to mind. They're not sexy, but they are one of the reasons why Warren Buffet is as wealthy as he is.
Not only that, but often the grad students often don't actually know much about the subject being taught, at least when it comes to practical/lab courses.
Back in the days of yore, I was hired by my University to serve as an undergrad TA for a couple of the hands-on/practical courses in our Engineering department. I had done really well in those courses the year before, and the instructor respected my knowledge. It was a pretty good gig for me as well, given that I was one of the lab geeks who hung out at all hours of the night, and I have this soft spot for teaching/helping out those who are genuinely interested. The money they paid me was an added bonus, as it covered my beer for the semester.
Anyhow, after 2 years of doing this, a complaint was filed with the department that too many grad students weren't getting these TA gigs, and thus were being denied their rightful income. The next time the course rolled around, a new grad student was hired to TA these courses, who didn't know the material and I honestly don't know how he passed the TOEFL. In the end, because I'm a nice guy, I wound up doing half the TA work anyway because I'm a nice guy, but I didn't get paid for it.
The only place I use it is on my oldschool DVD player, which gets dusted off and used maybe every two years. It sits in my rack, with a component video link to my receiver, and an optical audio link... That way if a friend brings over a DVD (none of this newfangled BluRay stuff!), I can pop it in and watch it in its 480p widescreen glory.:)
The problem with ARC is that it's always been a bit dodgy as to whether it will work or not, and how it interacts with the receiver. Usually it needs some magic voodoo to get it working, and/or putting either your TV or receiver into a sub-optimal configuration for anything else... And also, potentially, the sacrifice of a chicken, goat, or young virgin.
Either way, if they would actually get it working, than it would be great not only for things like OTA broadcasts, but also potentially for stuff like Rokus or whatever else. In the end, I just use my TV as a monitor, and make heavy use of the HDMI switching capabilities of my receiver.
While this is a long dead thread at this point, the "Notwithstanding Clause" has some strong limitations on it. It can only be applied to sections 2, and 7-15. Secondly, any law that invokes the "Notwithstanding Clause" automatically sunsets after 5 years, and must be renewed by parliament. If it was an egregious violation of rights, it's likely the party that introduced the bill will be out of power by then, and the newly elected government can choose to either repeal, or simply allow the law to expire.
I think you're confusing Canada with a country that has a Bill of Rights.
No, but we have the "Charter of Rights and Freedoms" which is in many respects a much stronger document than your bill of rights. It has been a huge piece of jurisprudence in its 35 years of existence.
You're technically correct, which I suppose is the best kind of correct.
However, most standard calculators do simple "Business Math" and act more like an adding machine, rather than following proper BEDMAS order. This is the behaviour that most people expect. Say you're adding up a dinner bill then dividing by 3 to split it 3 ways. If you were to just blindly type in 5+2+3/3 on a scientific calculator, you're going to wind up with an answer of 8, which is obviously incorrect. If you do it on a business calculator, you're going to wind up with 3.33, which is the correct answer.
If you wanted a Canadian equivalent, it would be more like Alberta separating (from a financial stand point) however in that case the level of support is generally thought to be under 15% so it seems unlikely.
I wish they would... then we wouldn't have the pipelines being rammed down our throats.
So western/northern Europe, Canada, and and similar countries are all hell holes?
I'll try to remember that next time I go see a doctor of my own choice without paying a rediculous co-pay, or take a drink of water from my tap where it comes out clean and pure, rather than brown sludge.
Wow, has it really shifted that much? (or has US Netflix started to suck so badly?) Until recently it was definitely the opposite... their licensing for Canada was maybe 40% of the US catalogue.
This is only true in some traditions. Most mainline denominations (Lutheran, Episcopalian/Anglican, UCC, or whatever) are perfectly okay with cremation, burial at sea, or whatever else, as long as it's done with dignity and respect. The funeral rites that are in the hymnals/worship books tend to contain options/appropriate words for all of the above.
Heck, last year even the Vatican has said that it's acceptable for Catholics to be cremated, as long as the ashes are kept together in a sacred/blessed place.
So yeah, don't paint all Christians with the same brush.
Actually they don't, Russia has 4300 deliverable weapons, while the US has 4000. At the height of the cold war, the Soviet Union had roughly 40,000 warheads while the US had 23,000. The difference was made up because the US delivery systems were much more accurate.
It's more that a missile launch will cause all hell to break loose in Russia and China, as the plume will be picked up by their observation satellites. Something delivered by bomber is much less likely to trigger the enemies that could engage in MAD.
Radiation from Japan made it all the way to the west coast.
While I generally agree with your point, the bit I quoted above is definitely scare mongering. Yes, Radiation from Fukushima hit the west coast. The reason why we know that is we're incredibly good at detecting man-made isotopes in concentrations that are at Homeopathic levels of dilution. So yes, we can detect the release from Fukushima, and no, it's not harmful. The level of radiation is far below what is received from cosmic rays, the thorium in granite, and whatever else in the environment.
If you're going to argue a point (again with what I mostly agree about) at least have your facts straight, please.

pretty easy to verify with wireshark.

Eh, CBC is about the best thing on the air, better than the tripe on Global or CTV.

The better analogy would be "If everyone is hitting the brakes to avoid driving off a cliff, shouldn't you do the same?"

Laser printers also require toner, which is extremely finely divided plastic powder. The very last thing you'd ever want to have in microgravity.

Only if you do the arithmetic in reverse polish notation.

Naw, the US went there to beat the Russians. After that job was done, there wasn't really a compelling reason to go back.
