I read that in the sense of, "Let's say that I'm in the position of being a general manager", as a hypothetical rather than something to be taken literally.

Unfortunately, I'm in the UK, where the selection is much more limited.

For example, Dell UK's web site lists exactly one laptop with a 17+" screen and SSD, and it is also a touchscreen and comes with Windows 8.1.

HP do at least promote the Windows 7 option (via Win8 downgrade rights) for the high-end ZBook laptops on their site. However, the pricing on those tends to make the closest equivalent Retina MBPs in specification look cheap.

Also, Microsoft UK don't seem to have any high-end devices at all within their Signature Edition range, so it's invasive crapware city all the way with a lot of the big name brands, even on their expensive, high-end models.

But the screenshots I've seen of Windows 10 still mostly look flat and/or garish, and it seems to be more a case of trying not to make the visuals too much worse than what is already available via Windows 7 than actually trying to be better. Another example is the icons, which have gone from being widely ridiculed to being... well, slightly less widely ridiculed... in all of the reviews I've come across, and with considerable justification if the examples I've seen myself were representative.

It's not just the visuals that put me off, though. It's also the fact that I use a traditional desktop PC with multiple large monitors, and I want an OS and software that work well in that kind of environment. I saw a review the other day of the new preview release where literally every screenshot that had substantial content in it also included the word "tap" somewhere, with obvious concessions to touchscreens that just don't make sense for a desktop workstation. This was one of the big problems with Windows 8, and it seems like with the Surface tablet hardware and Windows 10, Microsoft are doubling down on touchscreens. #donotwant #haverealworktodo

I'll wait to see what people say when Windows 10 actually ships and we're not just talking about preview releases and educated guesswork, but so far the signs don't seem promising. Windows 7, on the other hand, is tried and tested and works just fine on the numerous computers I use it with today, so as I said, if I could buy an approximate equivalent with newer and more powerful hardware right now, I'd be right in there. Sadly, I'm in the UK, and what you can pick up over here is quite limited compared to what you can get in say the US.

If I could find a good high-end laptop that came with vanilla Windows 7 instead of 8 and all the pre-installed extra junk, I would be throwing money at the supplier and begging them to sell me one. That has far more to do with avoiding more recent versions of Windows and their kindergarten, touch-obsessed UIs than it does with wanting a cheap upgrade when 10 ships.

Of course it does. It has the same advantages in terms of security and your visitors' privacy as any decision to host your own material instead of quietly using a third party service. Whether you consider those significant advantages is a different question, and whether your visitors would is a different question again, but clearly there is a difference.

I find this an interesting statement. Running the numbers, I find that you'd have to be using a rocket burning something rather better than H2/O2 (we're talking Isp >500 just to reach escape speed, much less to reach the target rock) to allow two launches of a delta-IV heavy.

Huh?

The fact that a Delta-IV Heavy has a LEO payload of over 27 tonnes is a fact. You don't need to "run the numbers". As for the kick stage, I didn't specify a propulsion system - for all we care (since we haven't established a timeframe), it could be an ion drive and not even take a rocket so large as a Delta IV-Heavy.

Meanwhile, the Falcon Heavy is to make its first launch this year, with double the payload of a Delta IV-Heavy. And as was mentioned, the Tsar Bomba was not optimized to be as lightweight as possible.

And this entirely ignores that noone actually has a Tsar Bomba sized nuke available to be detonated.

Oh, and you didn't allow for a backup

It's almost as if I didn't add "with enough advance warning" for that scenario and leave what "enough advance warning" is unspecified. But if there's another rock the size of the Chicxulub impactor out there and we don't see it until the last second, we deserve to get hit - we're no longer talking about a 50 meter spec (Tunguska-sized), rather a rock with a cross section 30% bigger than the island of Manhattan. We're talking about an impact of a scale that happens once every hundred million years or so.

OMFG people!

It is not only possible, but the easiest option, to "blow them up Armageddon style" (minus the drilling and the like). There's a lot of simulation work going on right now and the results have been consistently encouraging that even a small nuclear weapon could obliterate quite a large asteroid into little fragments that won't re-coalesce, while simultaneously kicking them out of their current orbit. A few years ago they were just doing 2d calcs, now they've gotten full 3d runs.

Think for a second about what nuclear weapons can do on Earth. Here's the crater of a 100kt nuclear weapon test. It's 100 meters deep and 320 meters wide. You could nearly fit a sizeable asteroid like Itokawa inside the hole. And that thing had Earth's intense gravity field working against it and was only 1/10th the size of weapons being considered here. In space you don't need to "blast out" debris with great force like on Earth, you merely need to give it a fractional meter-per-second kick and it's no longer gravitationally bound. And the ability of a nuclear shockwave to shatter rock is almost unthinkably powerful - just ignoring that many if not most asteroids are rubble piles and thus come already pre-shattered. Look at the "rubble chimneys" kicked up by even small nuclear blasts several kilometers underground (in rock compressed by Earth's gravity). Or the size of the underground cavity created by the wimpy 3kT Gnome blast - 28000 cubic meters. Just ignoring that it had to do that, again, working against Earth's compression deep underground, if you scale that up to a 1MT warhead the cavity would be the size of Itokawa itself.

You of course don't have to destroy an asteroid if you don't want to - nuclear weapons can also gently kick them off their path. Again, you're depositing energy in the form of X-rays into the surface of the asteroid on one side. If it's a tremendous amount of energy, you create a powerful shattering shockwave moving throughout the body of the asteroid. If it's lesser, however, you're simply creating a broad planar gas/plasma/dust jet across the asteroid, turning that whole side into one gigantic thruster that will keep pushing and kicking off matter until it cools down.

The last detail is that nuclear weapons are just so simple of a solution. There's no elaborate spacecraft design and testing program needed - you have an already extant, already-built device which is designed to endure launch G-forces / vibrations and tolerate the vacuum of space, and you simply need to get it "near" your target - the sort of navigation that pretty much every space mission we've launched in the past several decades has managed. In terms of mission design simplicity, pretty much nothing except kinetic impactors (which are far less powerful) comes close, and even then it's a tossup. Assuming roughly linear scaling with the simulations done thusfar, with enough advance warning, even a Chicxulub-scale impactor could be deflected / destroyed with a Tsar Bomba-sized device with a uranium tamper. Even though it was not designed to be light for space operations, its 27-tonne weight could be launched to LEO by a single Delta-IV Heavy and hauled off to intercept by a second launch vehicle.

This is a popular claim, but what little real data I've seen says quite the opposite. There are so many different minor versions of a library like jQuery that the chance of any given visitor to your site actually having visited another site using the exact same version from the exact same CDN within the cache window turns out to be pretty low.

There are still reasonable performance-related arguments in favour of hosting static content on a CDN, and for splitting resources across domains unless you're in SPDY or HTTP/2 territory, but those aren't quite the same issue and you can avoid them without resorting to loading libraries from third party hosts you don't control.

Uber drivers are subsidized by everybody else. Taxi drivers have to pay high insurance rates because the act of driving a long distance every day for a ton of strangers is a job that inherently leads to a much higher statistical rate of payouts. If they're driving as a taxi on regular car insurance, it's you that's paying the bill for their swindle of the insurance system.

Yeah, wouldn't that be great if I had linked it in my first post, and then if you had actually read my post well enough to see it?

Ah, I see. I think I have erased from my memory the time when my daily commute was measured in hours -- I could only stand it for a few years early in my career and then gave up and moved to a job closer to home. I do sympathise, though.

How do you come to that assumption?

By linking to a peer-reviewed paper on the subject?

A nuclear warhead has lots of trouble to even "hit" an asteroid.

Essentially every space mission we have launched for the past several decades has had to navigate with a far more precision than that needed to get close to an asteroid and activate a single trigger event when close by.

Only the first few times. Then it's just annoying.

We send spacecraft on comparable missions all the time. And it doesn't really take a spectacularly large payload to destroy (yes, destroy) an asteroid a few hundred meters in diameter. 1/2-kilometer-wide Itokawa could be blown into tiny bits which would not recoalesce, via a 0,5-1,0 megatonne nuclear warhead, a typical size in modern nuclear arsenals (in addition, the little pieces would be pushed out of their current orbit).

I know it's a common misconception that "nuking" an asteroid would simply create a few large fragments that would hit Earth with even more devastation, but that's not backed by simulation data. And anyway, even if it didn't blow the asteroid to tiny bits (which simulations say it would) and even if it didn't push the remaining pieces off trajectory (which they say it does), anything that spreads an Earth impact out over a larger period of time is a good thing - it means the higher percentage of the energy that's absorbed high in the atmosphere rather than reaching the surface (less ejecta, lower ocean waves, a broader (weaker) distribution of the heat pulse, etc), the weaker the shockwaves, the weaker the total heat at any given point in time, and the more time for Earth to radiate away any imparted energy or precipitate out any ejecta cloud. If the choice is between 15 Chelyabink-sized impactor (most of which will strike places where they won't even be witnessed) or one Meteor Crater-sized impactor (same total mass), pick the Chelyabinsk ones. 50 10-megatonne meteor crater impactors or one 500-megatonne Upheaval Dome impactor? Pick the former. The asteroid impacts calculator shows the former generating a negligible fireball and 270mph wind burst at 2km distance, while the latter creates the same winds 25km away (156 times the area) and a fireball that even 25km away is 50 times brighter than the sun, hot enough to instantly set most materials on fire.

But that's all irrelevant because, quite simply, simulations show that nuclear weapons do work against asteroids.

What we need is enough detection lead time to be able to launch a nuclear strike a few months before the impact date (to give time for the debris to disperse). There is no need to "land" or "drill" for the warhead. There is no pressure wave; instead, an immense burst of X-rays is absorbed through the outer skin of the asteroid on the side of the explosion, causing it to vaporize (unevenly) from within, especially near the ground zero point, and creating powerful shockwaves throughout its body. In addition to ripping it apart, the vaporized material and higher energy ejecta flies off, predominantly on the side where the explosion was detonated, acting a broad planar thruster.
