I didn't care much until I got a plasma TV. Only after I run it for a while in the summer I realized that 500 W is a lot of extra heat for my living room.
The whole "keep Mars sterile" will go out of the window as soon as we put humans on the surface. It's impossible to 100% decontaminate the space suits before every single EVA. So we better figure out first if there's any indigenous life form close enough to our own make-up (if we find living silicon on Mars we probably didn't transfer it, but anything DNA based would be highly suspicious).
I've worked on Mars sample return projects, and the requirements are pretty damn strict. But guaranteeing that not a single mold spore survives anywhere is pretty much impossible.
I think it was more a case of "we don't need no stinking warrants anymore". An institutional mindset assuming that "we're at war" automatically removes all constitutional protections; not unexpected if you look back in history at the suspension of habeas corpus during the civil war, or the mass detention of natural born (but of foreign origin) citizens during WW II.
I wouldn't so much worry about the cyclic loading of your bristles (after all, you can replace those every trip if needed). I'd more skeptical on the stability of your tether line, the idea of vibrating a 100,000 km tether of an extremely stiff material sounds like the next fatigue induced disaster (see Comet, DeHavilland). And don't forget the forces involved here; you're trying to play Jojo with an aircraft carrier weight.
When this story broke two months ago, the Sprint claim was that Cogent was having an unbalanced share of the traffic, and that was given as reason for depeering; mostly due to Cogent signing up large numbers at 10% of the price of Sprint and the other tier 1 ISPs. Makes you wonder if Forbes has an axe to grind there now.
No you're not misreading, the facts she was convicted off would have been the same if she'd been on facebook trying to talk the kid out of committing suicide. What made this application of "law" so troublesome.
Because daddy got convicted in a DUI 10 years ago, the computer can now match the son's DNA they recovered from a rape victim as being related to daddy. What greatly limits the number of people they have to examine, and also will give the police probably cause for obtaining DNA search warrants on all relatives.
One of the core protections in the US legal system is that you cannot be made to testify against a close relative. That niche just got filled nicely by DNA cross matching.
There are two different technologies for SSDs, single and multicell. The former is used in the $600 for 32 GB enterprise drives, the later in the $100 for 128 GB cheapos. The MC drives are the ones with the low write cycles. But if you use your SSD in a fast read-little write application like a database server it lasts forever and you can take advantage of the blazing read spead (most write performance I've seen isn't much ahead of a good HD array).
Guess you never bought any of IBM's Deskstar disaster series. I have a drawer full of these, none made it past 3 years. The drives were so bad, IBM sold the division, to Hitachi I think.
I'm afraid the answer to that question is one of those that gets black helicopters flying over your house;)
My guess is that the hydrodynamic flow around the stern of advanced submarines is so optimized that you don't get a loss of laminar flow along the surface - in that case the dimples would actually make things worse.
As I said, higher density means lower required velocity to transition from laminar to turbulent flow. The change in density is about a factor of 20 higher than the corresponding change in viscosity.
And Reynolds numbers aren't really applicable in transition regimes, but I'm not digging out my BSL.
It's also important to mention that it's a speed dependent phenomenon. I remember a discussion about this when they started with dimpled motorcycle helmets that, in air, the effect only works around 100 mph and up, and was useless for the average motorcycle driver. In water, with it's higher density, this regime seems to be effective at much lower speeds, so I haven't seen any dimpled submarines, yet.
While the potential of profiting monetarily from a global meltdown after a nuke on the oilfields might be greater, why would you? After all, what to do with a trillion dollars if Monaco has closed down due to a lack of customers, and all you can look forward to is an afternoon at the Atlantic City boardwalk?
It's not the uranium they are interested in (it's 238 anyway in the tamper, not 235)it's the softball size chunk of plutonium that's hard to get. And the basic principle of the Nagasaki bomb has been described well enough for a terrorist group to rebuild; while your standard suicide bomber might be the uneducated peasant, they have plenty of educated people that can do the calculations for them. Don't forget, that was done with 1940s technology the first time, and they have 60 years of knowledge leakage to work on.
Unless the nuclear warheads went off (what someone would have most likely noticed) the radioactive material is uranium from the tamper and plutonium from the primary. Both are "harmless" from a radioactivity point of view, so plutonium is extremely toxic. Standard chemical protection measures would have been sufficient.
What I hated most was their continuous "bait and switch" advertising. Even 10 min after opening the items in their weekend flier were "sorry, sold out, but we got this piece of junk here that costs only $40 more".
That's a bit extreme, simply write a bot program that can do "meaningful" judicial exchanges with the person in question. Let him have his fun writing long memos, and the program sends him back memoranda, motions and decision. He's happy, and no one else notices.
You need the control to make sure your "lander" doesn't roll. You only have one side of the vehicle protected via tiles, if you expose the other side you get fried astronaut with your fire work.
In regards to the chute, weight is everything at the orbiter stage, and landing gear adds a lot of weight. And if the main chute fails, I doubt you could manually exit the vehicle in a supersonic slip stream without ejection seats (which again are way to heavy).
Since it's not reusable, the fragile heat resistant tiles are not a problem. The shroud is for aerodynamic control during launch, you can see in the video that the vehicle is a lifting body; have it sit exposed on top of the rocket would give you huge off-axis forces due to drag/lift.
Single stage to orbit doesn't make sense from a fuel economy point, you need a lot of big engine at the beginning, why accelerate all that mass into orbit? Ditto on reentry, you have to bleed off all that additional energy you put in, requiring lots more of those fragile heat shield tiles.
My guess would be military - science people are usually pretty flexible in their choice of OS, especially if there's a pretty good reason to go with a different one than the one chosen.
What leaves the question - since you can't patch via your low latency connection, how long until a script kiddy finds his way into your remote system?
Been a while since I've lived there, but they didn't have that type of set-up. Weekend care was usually done by "duty call" doctors, basically you could check the paper which doctors where available on weekends, and they had limited hours. Since everyone takes all health insurances, cost was not an issue.
Having lived in both a country with mandatory health insurance (Germany) and the US - there is a difference. If you're in the US, and have good insurance, you generally seem to end up in nicer facilities. Not necessary better care, but hospitals, at least in my area, seem to be in better shape.
Having said that, I would trade back to the German insurance in a heart beat. Every time something is not covered by my US insurance, the out-of-pocket expenses balloon, and there is no way for me to get my insurance to expand their coverage. Add the lifetime benefit cap that prevents me from getting the help when I really need it, and it becomes a lot of eye wash. The German model is assessed as a tax, with a cap based on what you'd pay when you reach the "opt-out level" (You don't have to use public insurance in Germany if you can afford to buy your own, the cap used to be around 100k yearly income). The rumors of "don't get a bed for 5 years" are just bullocks, it's not any more difficult to get your doctor to see you in Germany than it's in the US. And at least insurance acceptance is universal, so if your employer switches insurance carriers you don't have to switch doctors.
I'd love to see a universal HMO be established here, one that can't drop you like a hot potato if your get sick, or flat out refuse to let you in for "pre-existing conditions" if you change jobs.

Actually, ours were all made in Thailand.

There are four rain forest belts, one around 20 - 30 degrees latitude, and one in the 60s, in each hemisphrere, driven by the trade winds.
