24GHz is license-free
and the gear is a bit under 10k euro per station. A bargain, really
It's not the cable
it's the connection speed. 100BTx is limited to 100m, at 10BT you can get up to 185m (with a good-enough cable, of course). Signal reflection, propagation delay and crosstalk are what's limiting. Given that you'd be connecting to an ADSL line that does 2Mb/s on a fair day, downhill and with tailwind, nailing your switch ports to 10Mbit doesn't sound like it would stomp on your bandwidth.
For that matter, I've reliably run 85Mbit PowerLan gear over 200m of standard extension cord cable in a point-to-point setup. Effective speed was 3 to 3.5Mbyte/sec, so not too shabby.
The first thing you do
is feeding a nylon cord through the hosepipe (just duct-tape a vacuum cleaner to the other end and feed in the cord), then with the actual cable you pull a second cord. This allows you, given sufficient diameter of the hosepipe, to pull a second cable if the need arises, although it's usually better to pull back the existing cable and feed it back in together with the new one.

It's got vast lakes full of methane, for crying out loud. The same stuff people on earth use to heat their homes with. But maybe they lack gas burners on Titan.
"the obvious and tangible mistake that Ford haven't actually made cars in Dagenham for the best part of a decade, "
That would tie in perfectly with the police response, which we all know to be timely and accurate, surely.
The problem is
that you appear to fail to see "telll someone to buld a PC to measure" as equal to "build your own" as opposed to "buy cardboard box at $retailer with manufacturer-made computer in it".
"Nobody is forcing you to buy Windows."
Try buying a PC or laptop without some form of Windows preinstalled. There even was a time when Bill equated selling OS-less computers as an incitement to software piracy, because obviously noone in their right mind (or left) would be installing a non-Windows OS on them, and refusing to pay for crap that they'd not be using.
Yes, you can get a refund now. Which is a comparatively recent development. And of course you could build your own, which simply isn't for everyone, and somewhat hard to do if it's a laptop you need/want.

Designers and architects
should be subjected to the consequences of their design decisions. Of which "being woken up at 02:30 by a wonky program" would be just a minor nuisance.

"rough handling" or "very rough handling"?

"You don't burn books. So we took it out the back and shot it"
This was about a book by the founder of the cult of fictionology, but the same sentiment applies.
(I myself have treated that pile of dross with an angle grinder and an alligator saw. Unsurprisingly, he book lost)
Oh yes they do, kindof. The scientifically advanced way
They simply feed the tinsel into the particle source whatsits,crank up the accelerator thingamajigs a bit, then continuously adjust the collision aim doodad so that the point of collision gradually moves along the entire length of the tunnel. You can see the result of those collisions in the pic in the article; if that's not festive I don't know what is.
SCSI was no Apple first
It was an established industry standard already, although not really common in prebuilt desktop systems. Computer shops' price lists were not that much shorter for the SCSI section than for the others (MFM/RLL or IDE) though, so they sure were used by the DIY crowd. SCSI disks were only a bit pricier than the others then, too, otherwise Apple would not have chosen them. They then bastardised the SCSI standard to allow for cheaper cables ("ooh, with one ground pin for all those twisted pairs it will work just as well". Yeah, right), which did little to take away the SCSI reputation for being finicky.
WD coexisting with any other brand
required deep, intense voodoo, and it made no difference if the bus was SCSI, IDE, ESDI or ST-506.
And only now that those incompatibilities are really a thing of the past it is that a single drive per channel gets to be the common configuration. Of course, as all hardware (as well as software) sucks, you'll be getting incompatibilities between controller and drive to make up for it.
"Is there anything it can't do?"
So far no luck in getting it to do the dishes and feed the cat, but apart from that?
I've heard it's the single most manufactured IC ever.
Much better than x86
with its totally fscked memory model.
For a while I wrote testing software for modules for voice response systems, which were 68k-based. Mostly C, but with splashes of assembler left and right. Pretty nice-ish all around, but the 6502 is still favourite.
probably for the RS232 port, creating -5V or -12V out of whatever voltage the battery supplies. Switched-cap supplies aren't the black art that switched-inductor supplies are, though. You can even build a quite competent one out of a 555 oscillator, with a few additional caps and diodes.
And glasss-cased SMD diodes (MELF) are rare now, but not at all extinct.
Among other things, they've found it's a rather involved way to make piping hot custard with rhubarb crumble, and then only teeny tiny quantities thereof.
You forgot the most important bit: does she wear glasses?
So, they're pretty close to the Big Bang
After that, they can start looking for the Best one.
No holes in space-time fabric yet?

"Is that the Mediterranean or the Atlantic?"
Yes, that looks like the wing damage. And judging from its shape (detailed pic in the landing/recovery story), with two more or less straight edges at right angles, I'd say the wing hit one of the corners of the payload box. Supporting evidence is that it's the port wing, which can be seen tilting up on the release video.
You'd then want the box vertical as well. With a short U-shaped loop protruding from the rear of the plane (grabbed by a pin just like on PARIS 1), both ends of the U anchored inside the plane, so that there are no knots, twists or ends to snag on the edge of the hole. I'm still thinking about a mechanism to keep the plane from swinging (excessively) relative to the box, which would not be susceptible to icing.
Same idea, different location (they do have more than one in that city)
I don't think it'd have effect immediately, especially not at 89k ft.
You may want to ask
how well they work at 25 miles up. Burning requires not only fuel but also oxygen; the latter is pretty scarce already at the summit of Mt. Everest, let alone three times higher.
You'll also have the problem that controlling the resulting temperature (lithium batteries dislike overheating even more than freezing) will not be a simple task. Beef up the camera battery a bit, add a controller and a heating element, and you're set.
He should of course land right here: http://maps.google.com/maps?q=51-57,+rue+de+Courcelles,+Paris,+France+75008&oe=utf-8&client=firefox-a&ie=UTF8&hq=&hnear=57+Rue+de+Courcelles,+75008+Paris,+Ile-de-France,+France&ei=3wvQTMdzxofhBubvxYcH&ved=0CBQQ8gEwAA&t=h&z=16
Immediately after the release you can see the camera view change from "swaying" to "tumbling", which would imply the main box is also falling freely.
Some mechanism with a tensioned spring that can only pull back the release pin once the balloon bursts, most easily implemented, I think, with a cord running from the spring to the balloon.
And the plane hanging nose-down under the launch box will probably make it drop away faster, decreasing the possibility of a collision (as I think has happened, judging from the shape of the hole in the port wing).
I'm no rocket surgeon
nor a brain scientist, but I don't see wind as much of a problem. You're launching from a balloon, which will be drifting with the wind; the plane itself has no propulsion and its (horizontal) speed respective to the surrounding air will not be vastly different from lower altitudes. Only air density and thus air resistance will be a factor.
Of course, if Chuck did indeed perform a steep dive from the release height to somewhere between 5000 and 10000 ft (165..330 double decker buses) his craft will have reached an appreciable aerial velocity which it would have retained initially when pulling out, but given the plane's aerodynamic profile and its weight it will have slowed down rather quickly and settled at a thrown-paper-plane airspeed and flight attitude.
Considering that the hole has two straight edges at right angles to each other, and it's on the port wing which tipped up as the plane banked after release, I'd venture the guess that it was caused by the wing hitting one of the corners of PARIS' box.
Just trim by moving weight
You have one end of the concertina pipe moving anyway, add weight to suit if you actually want to go that route. No fiddly mechanism to transfer the movement to trim flaps.
is maybe a bit bigger and heavier than the keyfob/spypen cams, (133g total, with the camera at 29g), but it has the advantage of having the actual recorder separate from the camera, which would help with weight placement and the keeping warm of the recorder battery.
In what order
will they be doing the other stations? The last one should be, for obvious reasons, Mornington Crescent (alternatively known as Concerning Torments), but will they be following Trumpington's Variations? Tudor Court Rules? Standard?
Yes, stupid you are
HSDPA/HSUPA, or even just UMTS/3G is just the trick to connect some local network to the Great Wide Internet when there's no suitable cabling around. These,and their predecessors have bene around for a good ten years, and are pretty ubiquitous nowadays.
But if you can't grok those newfangled technologies, just wait for the bus that trails a spool of telephone wire. Alternatively, trolleybuses may have Powernet installed.
A liter of water (at 277K and 1*10^6Pa) is indeed 1kg, but try varying the temperature or ambient pressure a bit and you'll be sufficiently off to throw any semblance of precision out the window. And precision counts in definitions. So anything that doesn't rely on other measurements is to be preferred: [large_number of stable_atoms] is quite a bit better than [amount of fluid that goes in a container of some size at this temperature and that pressure]
"the SI units of meter, second, second, ampere etc"
The first second, or the second?
If the top and bottom had straight edges, you would be more likely to chip off a few atoms when you set it down. At least, that's the reason I can think of for doing it
You may want
to get hold of the Superdupont comic, the first album. Okay, it's about the meter, but one of the stories is quite like your plot.

Then of course being FaceTious means you might have to FaceTheConsequences.
The way I read the story, someone else, not the eyepokee, slapped the stripper.
the URL as given works fine, and is the actual URL of the article on the Wiener website. When you remove the ellipsis you'll get redirected to a page ... whose URL has them. Just a simple refresh would have been sufficient anyway.
And learn to spell Wiener, you twat.
Just do a page refresh
or copy/paste the URL, and it's fine. Probably something to do with the http-referrer which they decided not to like.
For output I'd expect it to be able to control whistles, the sound of which can be picked up and fed to a FSK (75 or 110bd, maybe 300bd) modem. The input converter could be any device that spits out paper tape or punched cards
