During job interviews, Microsoft used to present brain
twisters to candidates (maybe still do), looking for
ingenuity, resourcefulness, etc.

One item: "How would you move Mt. Fuji?"

You are an interviewee. How do you answer?

If it's relative to any thing smaller than it, I'd try to move the

Where to?

If we just want an horizontal translation, I would pierce parallel
tunnels underneath, and place wheeled supports, and then pierce other
parallel tunnels between the first tunnels, and place wheeled
supports, and so on until there remains no rock between the parallel
tunnels. Then the mount would be over my wheeled supports, and I
could drive it someplace where (of course, in the mean time a very
large road would have been build to the destination.

Now, Mt Fuji is 3776 m high, so the weight under the summit would be
about 5*3776 = 18880 tons. Perhaps we can't make wheeled supports
strong enough. In this case we could use a bath of mercury. We would
have to pierce only little holes, fill them with mercury, and pierce
other little holes in between, etc until the mount is detached and
flots on the mercury (eg. like the Eiffel Tower). Then we would just
have to make a mercury canal where to we want to move it, and call
Tokyo metro pushers to push the mount. (In case of countrary wind, we
could pump out the mercury and let the mount stand in the canal bed.)


If we want a vertical translation, I would go for the cut and slice
method, using big lasers, I would cut it in little cubes, and wrap
them up, and call UPS or Arianespace, depending on the destination.

I think that such a question serves more to study how you will
"respond" to such an open-ended question while under pressure than it
is to see what type of technical solution you may come up with. In
fact, attempting to answer in a technical way may just open the door
nice and wide so that you can walk out and away from the unsuccessful
interview ( unless of course, you think anyone can easily just pop
off a viable technical way to move a mountain while sitting in an
interview ).

A peak is typically located by the coordinates of the
highest spot. If it's a smooth peak, the sensitivity of
that high spot is large to the movement of relatively
small amounts of material. So, small motions are easy.

Travel cost is large, though, I'd hire a local agency to
perform the work, and maybe a second to inspect it.

I'd prefer to work for a company where, if you have a would-be customer who
asks something along the lines of, "How do I move Mt. Fuji?" (i.e., some
near-impossible task), they're being serious and fully expect you to come up
with a serious answer rather than being cute or clever and telling them you'll
give them a photo of the mountain or that you don't need to do anything at all
because the Earth is constantly in motion anyway.

Of course, when someone asks you to do something that's close to impossible,
the only serious response is that you first need to find out a lot more
details as to what the problem really is and what the constraints are; in the
case of Mt. Fuji it's pretty self-evident that the first barrier you'll have
to moving the mountain is far more political than technical -- until you get
permission to move it, there's little point in spending many engineering
dollars worrying about how it's going to be done! (It's not uncommon for a
customer to e.g., ask you to move Mt. Fuji when in actuality all they want to
do is build a railroad from one side of it to the other and it's actually
perfectly acceptable to bore a tunnel through it, which ends up being far
faster/earier/cheaper.)

Microsoft were not the only company supplying a market, they
were the FIRST company supplying software to the domestic and
small business markets. IBM had OS2 but it arrived on the scene
too late; Apple were busy playing space invaders.

Same with VHS and Betamax VCRs. Phillips had a superior 4-head
recorder but the market was swamped with VHS movies, people
were not interested in freezing frames. Now VCRs are dead,
replaced by DVDs and freezing frames is no problem. DVDs
won't last long, they'll be replaced with non-mechanical technology.

Ford sold cars that were rubbish compared to Rolls Royce, but
they worked and were cheap and acceptable to the domestic and
small business markets.

The current interest in HDTV isn't really working, it only has novelty
value. The current definition (resolution) is acceptable for watching
any old movies. News broadcasts where people are recording events
on mobile phones are scarcely "high definition TV" but better than
no images at all. We can expect to see improvements in that.

There is a threshold of acceptability which Microsoft meets
for the domestic and accountancy markets, although the purists
will always demand better quality. That costs money and I don't
need a Rolls Royce or a Formula One racing car to go grocery
shopping. I do need groceries, a Ford is acceptable and so is
Microsoft Windows.

Waiting for some which is already here is probably a race condition,

Bing supports this (alas you can't make a link to the help page which
shows it):

"Advanced search options

Find what you're looking for in less time. Use the following symbols
to quickly modify your search term or search function:

Also google has something pretty close.

They're not really "horrible," though -- I've certainly had cars that broke
down more often than Windows does these days. :-)

The other thing to keep in mind is that you're kinda comparing apples and
oranges anyway: With an operating system, you add software that interacts with
the core OS in very close relationship, yet when there's a problem people tend
to blame the OS when, in the vast majority of cases, it's really an
application bug. Certainly one can argue that the OS could and should be more
"bulletproof" wrt errant applications, but wrt cars, while there certainly are
a few people adding turbo chargers or re-programmed engine timing profiles or
similar to their vehicles, the vast majority of "vehicle accessories"
("software") in no way interacts with the main control and propulsion systems
in the vehicle.

But the point I really wanted to make is... how did Microsoft become so big
when there were technically superior products available? The answer there is
basically Steve Ballmer. The guy has always worked far harder than the
average bear to drum up sales for Microsoft, and it's a classic example of
where good marketing can easily overcome technical flaws in a system.

likes to point out occasionally, in some ways it's worse than NTSC was.

But HDTVs (the physical televisions) have been phenomenally successful -- back
in the '80s and much of the '90s television sales were pretty stagnant, and in
the '00s LCD and plasma TVs really re-ignited the market, and high-definition
has just added to it.

Yeah, but that doesn't mean there aren't plenty of people ready and willing to
get out their wallets to new technologies that they find *preferable*.
Especially on a big-screen, very few people would *prefer* to watch, e.g., a
VHS taped copy of a movie over the Blu-Ray version! :-)

The thing is, it's not really clear-cut that the Mac OS, Linux, etc. *are*
truly better quality. Linux has a lot of attraction, though, because at least
by being "open" anyone can go and take a look and decide for themselves just
what the quality level is if they care to. But the fact of life today is that
*all* major operating systems now provide regularly (weekly or monthly) *lots*
of patches and security fixes, indicating that there is no one has a monopoly
on OS quality.

Yep, agreed. Outside of, "PC or Mac?," the vast majority of people don't even
what the other options *are*, and they do just fine.

Yes, but that has more to do with the volume of room space the old tube sets

Sure, and I'd have a better car/computer if had more money and
wanted one, but I can't honestly say I NEED a better car. As it is
I have twin screens, a GeForce 9800 video card, a TV card, an
X-Box 360 gamepad, a joystick, steering wheel and pedals, plus
the usual printer/scanner, mouse and keyboard, and it all works just
fine. I get the occasional glitch by playing Leisure Suit Larry Box
Office Bust and the TV card doesn't work afterwards without a
reboot, but so what? I just turn the computer off and go to bed
instead of leaving it in standby as I usually do. Then there is always
the standby computer, and the old standby computer out in the
shed. The darn things are so cheap nowadays anyone can have
several, but I won't buy a laptop on the principle that I spill coffee
or vodka and coke on Ł6.95 keyboards regularly. The vodka is
more expensive and Coca Cola isn't cheap.

Correct, which is why the interview weeds out the weak links.

"How would you move Mt. Fuji?"
Hire lawyers, get a contract signed by the Japanese government
and payment arranged for the feasibility study.
Hire geologists to estimate the difficulties... yada yada yada...
just as it is done in normal business. Moving Mt. Fuji is just
another engineering project, much less difficult than reaching
the Moon. One presumes the Japanese want it moved for a
reason and have some idea where they want it moved to, but it
will not be cheap; it could be a lucrative contract, so there will
be competition for it. Your facetious answer will not win the

Applications should *never* be able to bring down an OS. If that happens it
is the OS's fault anyway. OSs aren't applications and have to be held to a
higher standard, as should their programmers.

Well, if you drove it at 50 mph for 100,000 miles it would be worn out

Agreed, I'm just saying that many people jump to "Windows sucks" when their
applications crash (...but the OS itself is holding up just fine...) -- many
people just don't have a very clear distinction between the OS an apps.

There's some You Tube video where someone went around asking people on the
street what a "web browser" was, and not surprisingly very few people gave
reasonably correct responses. (I think the motivation was that, to get people
to switch from Internet Explorer to FireFox or similar, and the point was that
FireFox is never going to largely display IE because most people wouldn't even
know the option to switch existed or why they'd want to...)

Well, I'd say they do do software engineering. But that's all they do,
and it's pretty ordinary. In areas where some special ability is called
for (for example, defining interfaces) that ability seems noticeably absent.

All the important innovations (windowing sytems, Internet, WWW, etc.)
have come from elsewhere with Microsoft playing catchup.

actually google allows you to do that, the "Advanced search" is
basically a GUI for composing these operators, but if you know the
syntax, you can do really complex queries.

+word : search for exact word (disables synonym searches)
-word : excludes pages containing the word
~word : also searches for synonyms
A OR B : matches one of A or B
A AND B : matches both A and B (default behavior when no OR)
"..." : searches for phrase in quote (instead of their words)
foo * bar: wildcard search

and there are operators like:
site: www.mysite.com : site-specific search
inurl: : search for the word in URLs
intitle: search for words in <title></title>
filetype: (e.g. pdf, doc)
related: search for pages related to another page
define: search for definitions (dictionaries, encyclopedias, etc)

the advanced search exposes many more, such as searching for page
updated between a certain time range; or distributed under specific
license; or pages from certain area; or for numbers between a certain range.

More techniques:
http://www.google.com/support/websearch/bin/answer.py?answer=136861
http://lifehacker.com/339474/top-10-obscure-google-search-tricks

However, frequent Googlers would notice that these advanced operators
are really rarely needed, because Google is very good at mind reading
(and sometimes it's so good, it could freak you out). For example, when
I search for "python", it directs me to python programming language
website, not to snake-taming website, while a zoo keeper usually would
get the reverse result.

I am a zookeeper who would LIKE to learn Python programming language,
but all I ever get on the Google results are stupid snake sites.

At first I thought it would be an impossible thing to do to, but from
a google search, I found this that describes the details of moving Mt.
Fuji to Mojave, California.

http://w-uh.com/articles/030917b-really_moving_Mou.html

"Okay, we want to move Mount Fuji... So we have to make some
assumptions. First, we have to define what "moving" means. So let's
say we are going to move the entire mountain to Mojave, California.
Hey, it's desert, there's a lot of room out there.

First let's consider the overall technique. We need a bunch of
dynamite to blow up the rock. Then we need bulldozers to pick up the
rock and put it into trucks. We use the trucks to carry all the rock
to the nearest airport, where we have a fleet of 747 cargo jets
waiting (and loading equipment). From there we fly the rock to
Mojave, unload it from the planes, transfer it back into trucks, move
it into the desert, and dump it. And we'll need bulldozers to push
the rock back into shape.

There is a philosophical question as to whether, having moved all the
rock and reshaped it, we still have Mount Fuji. We certainly have the
parts to Mount Fuji, but is the mountain still the mountain after it
has been moved in this way? I'll leave the philosophy alone (for
once!) and just say we stipulate up front that moving the parts is
equivalent to moving the mountain.

Next we have to figure out how big the mountain is... Well, I Googled
and figured out it is 3,776 meters high (about 13,000 ft.). I might
have guessed about 12,000 ft. without Google because that's about the
height of Mt. Whitney (the tallest peak in the California Sierra
Nevada range). The shape of this mountain is nearly a perfect cone,
with the width of the base about three times the height. As you know,
the volume of a cone is given by:

(base area * height) / 3 = (πr2 * height) / 3

So this means the volume of Mount Fuji is approximately:

(π * 18,000 * 18,000 * 12,000) / 3 ≈ 12 x 1012 ft3

That's a lot of rock. Next let's figure out how much this might
weigh. Imagine a rock the size of a cubic foot. Could you pick it
up? I'd say barely. It probably would weigh about 100 lbs. So that
means we have a lot of heavy rock to move:

12 x 1012 x 100 lbs = 12 x 1014 lbs = 6 x 109 tons

Cool. Okay, so how many 747s would we need? A 747 can carry about
500 people with all their luggage. The people weigh about 150 lbs on
average, and their luggage probably weighs about the same, so we're
talking 500 x 300 = 150,000 lbs, or about 75 tons. Let's say for
cargo purposes we could carry 100 tons. Would that be the limiting
factor, or would volume? Well, if each ton is about 20 cubic feet,
then we're talking about 2,000 cubic feet. That's 10 ft x 10 ft x 20
ft, so clearly the size of the rock would not matter. (Actually since
the rock would be broken up it would take more space, but not that
much more.) We would therefore need 6 x 107 = 60M plane flights. If
we had a fleet of 1,000 planes flying in parallel, and each plane made
two flights per day, it would take 30,000 days or around 100 years.

That's a long time, but this is a big project. Many of the great
European cathedrals took over 100 years to build, as did the Great
Wall in China and the Great Pyramid in Egypt...

What about trucks? Well, I'd guess a really big dump truck could haul
25 tons. (That would be about 5,000 cubic feet, or 10 ft x 10 ft x 50
ft, roughly speaking.) So we'd need four times as many trucks as
planes. I don't know how close the nearest airport is to Mount Fuji,
but let's assume we could make two trips from the mountain to the
airport each day (same as plane flights), so we'd need 4,000 trucks.
No problem. Oh yeah and we'd need about the same number of trucks on
the other end, too.

Now, about those bulldozers. Well, let's say it takes one bulldozer
to load one truck. We assumed the trucks make two trips per day, so
now let's assume a trip is really four hours of loading, four hours of
driving, and four hours of unloading. That would give a bulldozer
four hours to do the loading, and that seems reasonable. So pencil in
4,000 bulldozers. I'm sure there would be some traffic problems with
that many bulldozers roaming around the mountain, but we could deal
with that. No worse than the Ventura Freeway at rush hour :) And as
with the trucks we'd need the same number of bulldozers to rebuild the
mountain in Mojave.

So, that's how I'd move Mount Fuji into the Mojave desert. Give me
8,000 bulldozers, 8,000 dump trucks, 1,000 cargo jets, and (of course)
the people to man them, and it would take me about 100 years. No
problem. "

747s can lift upwards of 250Klbs with a gross weight of 1.2M. You're close.

IT's certainly not known with 100% certainty but it is believed that the Great
Pyramid was built in about 10 years. The entire plain at Giza was on the
order of 100 years.

Nice numbers, but you left out the most difficult and time-consuming part of
the entire project; government red tape.
