Because it's a test of the whole stack from what I understand. There may (for example) be a destructive resonance that could destroy the rocket in flight which could be detected during an engine test, which only occurs when the payload is installed. You obviously want to find this out now when you can abort a test and find out what's causing the resonance, rather than when the rocket blows up ten seconds after launch.
"All the problems with wind" is a bit of an overexaggeration. In fact, the video nicely shows how resilient it is. For instance, the first clip is of a wind turbine on fire. Notice how the rest of the wind farm is not on fire. The wind farm would have perhaps lost 2% of its capacity, but it has resilience in numbers.
To start with, yes, I think the UK needs new nuclear capacity - we need *something* that's not coal that is good at doing baseload.
But on the other hand: from the point of view of the National Grid, wind does have certain advantages:
* Each generator is small and there are an awful lot of them. A generator or two going offline doesn't cause sudden capacity problems. However, a large nuclear generating plant going offline suddenly can cause a huge power shortage that can be solved only by shedding load (in other words, blackouts).
* The wind, over a period of the next few hours, is pretty easy to predict. The wind doesn't just suddenly and unexpectedly stop blowing. You can pretty much say the wind will be doing in 10 minutes time what it's doing now, and if it's not going to do that (e.g. due to the passage of a frontal system) you can at least know what it's going to do. Not so with a large powerplant which may suddenly go offline with no warning.
That's not quite right - old monitors aren't nearly as thirsty as you state and new ones not nearly as thrifty. My modern LED backlit HP monitor consumes 35 watts (which is a far cry from 0 watts!). My old Sun 21inch Trinitron-tubed monitor used 135 watts (quite a bit less than the 200W-400W you supposed).
The UK's manufacturing output is actually higher than it has been at any other time in history. It's just not goods that you have in your home (and it employs relatively few people).
- Ireland is also not in Schengen - The UK converted to metric for trade (Imperial units only used for things that are relatively trivial). In fact there were a series of "Metric Martyrs", traders in the UK who refused to move to metric were prosecuted by the UK authorities, so metrication *was* enforced. - Gibraltar is not in another country, despite spurious claims from the Spanish government. The Gibraltar people time and time again have said they wish to remain British - but you seem to want to force them to be ruled by the Spanish government (and you go on about "rights"!). The fact it is attached to the bottom of Spain makes it no more a part of Spain any more than Ceuta and Melilla are part of Morocco even though they are physically attached, or Portugal a part of Spain despite sharing the Iberian peninsula. - The UK isn't the only country that kept its currency. Denmark did too.
Spain should never have adopted the Euro, it has in part ruined your economy, as it has damaged Ireland, Italy, mortally wounded Greece etc.
While a cyclist will almost certainly get hurt in a collision, when all the risks are taken into account, someone who cycles regularly is at less risk of premature death than someone who only drives. All things being equal, avoiding cycling to work and using a car instead while it reduces the chances of dying in a collision, it increases much more the chances of dying prematurely of diseases related to a sedentary lifestyle.
I know how to change a tyre (and other things, I've done a cylinder head job a couple of times), but the trouble I've had with it, especially at the roadside, is the gorillas at the last tyre place put the wheel nuts on with a ludicrously high torque setting. Last time I needed to do it, I had to use "The Equalizer" (one of those big 1 meter long socket drivers) and pretty much put my entire body weight on the end of it before the lug nut would even budge. All of the nuts were done up like this. One of the studs actually snapped because the overtorquing had weakened and stretched it.
I do agree that this is just quasi-religious bullshit.
On the other hand, if the universe were a simulation, there's nothing to say that simulating our universe only takes a trivial amount of whatever passes for matter, energy and time in their universe.
If the universe were a simulation, it's likely it would not be made of matter as we know it, energy as we know it or time as we know it or even have laws of physics as we know it.
The simulation need not be complex, merely large. You could have a simulation that merely applied (relatively) simple rules then simulated every particle, photon etc. It would not be possible to differentiate between a bug that was consistent (and in a simple ruleset, it probably would be) and an intended rule.
The simulation may not be "let's simulate a planet with people on it".
It may be on the level of "Imagine if there was this stuff, and these rules, what would happen?" and someone codes up the rules for particles of all types and equations for the space they are in, pack all the particles in one small space (the Big Bang), perhaps a random number generator to churn things a bit, then hit start - and see what happened over the next few billions of years. We, our galaxy, fiction books, and everything else would merely be an emergent property of this relatively simple ruleset.
If the universe were simulated, it's likely to be on a machine not made of matter as we know it with energy as we know it. We're just starting to observe the simulation ruleset by discovering relativity and quantum physics.
Under Windows, the sound on the monitor stops working after a random period of time, somewhere on the order of an hour. Also, the keyboard randomly ceases to work if plugged into the monitor's USB hub. The same monitor and PC running Debian doesn't have these problems - it's all solid. Additionally, Windows 10 will BSOD at times (usually about once a month) despite all drivers and the OS being at the latest level. Debian on the same machine has never crashed.
If you run a Debian system with supported hardware, I've found it to be very solid.
What makes a hearing aid (especially one that works by simple air conduction of the amplified sound, no different to headphones) a medical device, but a pair of spectacles not a medical device?
The Rolls-Royce Trent has been tested up to 115,000 lbs thrust (and I have to imagine this new GE engine will be tested to at least that, if not more).
All 8 engines on a B52G produce 110,000 lbs thrust. You could convert a B-52 to a single engined aircraft with one of these GE engines impaled on the tail DC-10 style, and it would probably perform better than with the original 8 engines! Well, until the sole engine quit of course...
Your concern is probably in the wrong place - aviation is only 2% of carbon dioxide emissions. Banning aviation altogether (all things remaining equal) wouldn't make a difference in our current trajectory.
It doesn't run an OS, it's a microcontroller. The code runs on the bare metal. At most you'll have a library of functions that can poke at the microcontroller's peripherals. The ARM M0 doesn't even implement a supervisor mode, let alone an MMU. Typically when you deploy code on these devices, it's literally just the code you wrote plus the C runtime (and in the case of python, there will obviously have to be a python runtime, python effectively becoming "the operating system").
Programming one from a tablet without a keyboard would be fairly painful, I imagine. Practically, you're going to need a computer even if you use the online IDE that's available on ARM's website.
In a typical school, certainly here, the PCs are locked down so hard you can't even open a command prompt, let alone program on them. School PCs can be used for little more than learning Microsoft Office skills.
The Pi was needed so there was a cheap way of getting a programmable computer that wasn't locked down hard.

The UK didn't veto it, more than one country vetoed it - the French and the Dutch both threw it out as well.

The problem with America burning is that it's full of nuclear weapons.
Well, except for Stansted airport. Regularly only have a third of the security gates operational, with a >45 minute wait to get through.
The same thing is true of Windows, though.
I have a dual boot Windows 10/Debian 8 system.

I was hoping for a scandal involving Bill Gates. Then we could have Gatesgate.
It does actually happen in the simulation video, at about 2:40. (2.39:27 to be exact).
Banning air travel will do nothing. Air travel only contributes about 2% of the CO2 output.
There has been no pause. It only looks like "a pause" if you cherry pick an outlier warm year and ignore the trend.
Even so, the modified bomber was so lumbering it wouldn't have made it very far across the Soviet border before being shot down.
