if you look closely enough, everything is quantized.
That's really not of concern to anyone building electronics though.
To someone building a modern CPU it absolutely is. They are
approaching the point where single electrons count, it can't
get much more quantized than thant.
If you look at the bottom of the fuselage, you can just make out the edge of a second engine's bluish cowling. It's mounted on the other side, also angled out from the aircraft, but largely obscured by the point of view of the image.
Thank you, I didn't notice that. Yes, this makes much more sense like that.
Now I can wrap my head around that rendering too.
I don't think they chose a very good camera angle for showing off the concept.
Indeed not. From this angle, it looks more like an Escher drawing than a feasible aircraft.
Most likely a colony ship would send smaller livestock, like sheep or goats.
Most likely, a colony ship to Mars wouldn't send any livestock at all.
The energy efficiency alone makes this a no-brainer: why grow food for it
to be converted to meat at a net loss of energy content if you can grow food
for immediate consumption instead?
I would fully expect some later mission to send animals to an established
and growing colony, but there is no real case to be made for livestock on
the first flight.
So when I say an oral history, I don't mean, "Form the beginning there was dolphin and it was good...". I mean much of what they are is physically and vocally instructed - just as humans learn.
That's "language", not "history".
So you are being deliberately misleading by using a term that means
something specific to express something else. Thanks for telling us.
I'd contend that "peak freedom" must have occurred before most countries began requiring passports or visas to pass through their borders. This happened surprisingly recently in most cases; e.g. the 1930s for most of Europe, IIRC.
Bad example. Most of Europe has dropped this requirement years ago.
In many places, the checkpoints at the borders aren't just unmanned,
they don't even physically exist anoymore.
Citation from there: "The real problem is the hundreds of thousands of other parts, some as apparently insignificant as a bolt or a washer, that are simply not manufactured any more."
There also was lots of "hands on" know-how by the people doing the actual metal
bending that never was properly documented. That's why rebuilding a working
Saturn V is likely to cost about as much as a new development - and then you'd
have a rocket using state-of-the-art 1960s technology and materials.
No way it could ever be certificated for carrying humans.
Oh, damn. You should tell that to the people working on the Solar Impulse.
They'll be glad for all the work they wont have to do.
Also, they can seek treatment for the mass hallucination of
the 24h+ flight last July.
We're still talking low power and relatively slow, and you are right that this
will probably never be a way to power normal travel - but "it" (meaning a purely
solar powered heavier-than-air aircraft) already has carried humans.
What Tribbler has done is created a P2P torrent search engine. I'm not sure if they're the first either (I swear I remember reading about some other client with P2P search a couple years ago)
Yup, the eMule/aMule network has had serverless search via the Kad Network for years. Works pretty well.
It has been decided at least two years ago to put the tracking filter rules in their own list, because they obviously don't belong in a pure adblocking list.
Yes, there had been complaints by people who wanted ads blocked but the tracking stuff left intact.
I often catch up on missed episodes on local TV channel sites and the length of adverts is very small compared to the normal ~25%. This really annoys me, the adverts are too short. What if I want to do something/check if anyone sent me a message/whatever during the adverts?
Then just wait until the show is over. How old are you, thirteen?
The question is a valid one, despite all the ridicule that is being heaped
on the parent. Why exactly don't we do low-speed, low-friction
reentries by using the upper atmosphere's low-density layers for slow
braking?
Slow reentry is a thing that has been seriously considered for a long time:
Just slowly drop down in increasingly dense air, use the increasing lift you
can get there to stay aloft, and wait. After a while, the spacecraft will be
low and slow enough to land, with much less stress on crew and equipment,
and without needing any fancy thermal protection shield.
And that's one of the problems: if your spacecraft has no thermal shield, this is
the only reentry mode possible. Emergency aborts from orbit? No can do.
So for manned missions, you better bring a heat shield just in case. And if you
already bring it, why not just use it? It's faster, easier, and more predictable:
The low-drag reentry trajectory and duration is dependent on the quite
variable conditions in the very high parts of the atmosphere. It would be
impossible to determine an exact flight path - and the point at which the
spacecraft is slow enough to "just drop" - in advance, up to not even
knowing on which continent the landing will have to happen.
Slow reentry is still a very alluing thing (this flaming reentry thing is just
so archaic, right?), that's why there are always a handful of people working
on it. At the moment, those are mostly Japanese as far as I know. There's even
a proposal for a JAXA project for an experiment with paper planes
as proof-of-concept.
Slow reentry might eventually become the thing to do, but we'll need a
lot more confidence in our spacecraft (no need for quick aborts) and
much more detailed real-time knowledge about atmospheric conditions
at the edge of space to make it practically viable.
We've had spy satellites with that capability for over thirty years - and much better ones than this spaceplane can ever be, since they have payloads considerably larger. (Think orders of magnitude.)
Do you mean the Space Shuttle? In case you don't, what are you talking about?
(serious question, I'd like to know what I missed.)
Yes they did.
In many parts of the Mediterranean, Roman shipbuilding over 1500 years ago
has permanently altered the ecosystem. Once a hill is bare, the soil doesn't
stay around for too long.
Also, big (= old) trees were needed for the keels in particular, and "big old
trees" aren't easily renewable.
This happened in Britain too (the Romans started it there, but most of it
happened later): The island used to be pretty much one single forest.
The FAA isn't claiming jurisdiction over space. They are claiming jurisdiction over US airspace. The airspace that any space vehicle has to pass through on the way up and the way down.
This would be suprising news to most space launch operators on the planet.
And to a good number of orbital mechanics people too:-)

JFTR, the movie in question is Moon.
The difference between C-sharp and D-flat? What difference? They're enharmonically equivalent to each other.
Only in a tempered tuning.

As far as I can see, there wouldn't be any without the footnote. ;-). Now that's a nice confirmation of the rule...
It's "owing to"

No they didn't.

If SpaceX can secure the funding they will design and build a super heavy lift which would give them capability of 120mT - 140mT to orbit.
It took me several tries not to read this as "120-140 Millitesla",
which this unit abbreviation resolves to in the SI system.
Way to even use non-standard unit symbols for standard units.

So what is the EasyPrivacy list then?

A large portion of the canon cameras support CHDK (canon hack devkit).
Just as a minor nitpick about nomenclature: No they don't.
CHDK supports the cameras, not the other way around.
And yeah, playing with it is really fun.
Serious answer: You've missed pretty much the entire history of US spy sat development.
No I haven't. But let me quote what you stated has existed for at least thirty years:
... an orbiter that is fully automated, can change orbit, and return to Earth & be refueled. (bolding mine)
Care to name a single example that isn't a Space Shuttle?

I was thinking yeah, that Mona Lisa is nothing but old paying and old canvas, why would someone pay millions for it?
I wouldn't, since it's sure to be fake.
The Mona Lisa is painted on wood.
Bullshit. Ships didn't require THAT much wood,
Yes they did.

Hopefully they have a different way of figuring it for cell phones than just the number?
Yes: The tower your phone is connected to.
It has never been anything else.
But they didn't table the bill.
<pedant>Tabling a bill means delaying it in committee, usually with an intent to keep it there until it dies. </pedant>
That depends on whether you are American or not:
The British Staff prepared a paper which they wished to raise as a matter of urgency, and informed their American colleagues that they wished to "table it." To the American Staff "tabling" a paper meant putting it away in a drawer and forgetting it. (pedant^2)
This announcement is somewhat different, though, in that it seems they have integrated an FPGA fabric on a traditional CPU die.
No they haven't - it's two chips in one package.
