Far too long. (At any rate, much longer than 3 years!)

That has been easied, the tax of owning a car also demands the car to be 
marked to be allowed to use in traffic. IE my other summer car is marked 
"not in traffic" atm, so I don't pay taxes nor insurances of it.

Oh comparisons! Here is a site that gives a Global Peace Index. Countries with a
"United" in their names don't do that well :)

  The "electoral process" gets a flat 10 in that list. I seriously disagree,
but that's another story.

  (Yes, I know that things are pretty good here in that field compared to
many other countries, especially the so-called "banana republics", but
I wouldn't give Finnish electoral system a full 10. Maybe a 9. There are
details which really grind my gears.)

There are so many ways to make comparisons that it sometimes seems meaningless. 
A score of 10 is a bit suspect IMO unless Finland is taken as the standard :)
Life expectancy and Infant mortality are good indicators. I was a bit surprised
that Finland scores 3 on Willingness to fight against the UK and USA's 2.
Initially I only looked at the ranking but looking a bit further at the figures
I see that the UK has 0% for "Number of visitors as % of domestic population" In
2001 there were 22.8 million tourists that travelled to the UK with 11.5 million
visiting London. No wonder it feels so crowded.
I don't trust this site completely but then that's internet rule #1 (in my book)

Two replies.

First, the particular point I was trying to make was that some people 
really don't have the 'lights' for it, or possibly, have the ability but 
never acquired the skills. So the situation is very embarrassing for 
them.  For instance, I preach writing things by rote to help memorize 
them.  Suppose writing is an excruitiating and nearly impossible task?

On a different tack, there may some circumstances and people where it 
might be argued that study is really an escape from the world,... 
guiltily so.  In other words at some point in ones development you have 
to cope with the world beyond books.

But you have good public transit, yes?  When I've been on vacation in 
Europe for weeks at a time, I never rent a car.  In the USA, it's really 
difficult to live most places without a car, except maybe in the middle 
of a big city.

That's high. Here it's usually closer to 30% all told on a car.

Same here. Well, I mean, the taxes go towards upkeep of the roads and 
such, but it's not like you directly see the money come back to your 
pocket. California car taxes are exceptionally high because we're so 
"progressive" here. :-)

Heck, you have to pay $100/year if you send in the form that says "I own 
the car, but I'm not going to drive it at all."  And if you change your 
mind and you *do* drive it, you wind up with a huge penalty/interest/etc.

You have to pay $10/month to the water company if you don't want them to 
run pipes to your house because you have (say) a well on your farm or 
something. Never quite understood that one.

Not quite that here, no. But you pay to receive the signal at all in 
most places, by paying the cable company. We never got a TV tax, but 
then we never got government television stations either.

Yep, yep, yep, yep. America has all those taxes.  Probably not quite as 
high, but we have em. I think the property tax on my house in California 
is something like $5000 or $6000 a year, around 1% plus "melo roos", 
which is interest on the bonds the local government sold to build 
schools and stuff. (Long story, that.) Plus taxes on water, sewage, 
trash collection, phone service, etc etc etc. Basically, everything has 
sales tax, and all the utility services have taxes on top of that. Phone 
service is a favorite dumping ground for taxes - probably 40% of my 
phone bill each month is 3% tax this, $5 tax that...

Oh, and we have "gift tax."  Someone gives you a million dollars as a 
present? Please give half to the government, thanks.

And your government doesn't seem to treat citizens like the enemy, as 
well. :-)

Then you've got at least 3 years of experience.  So that's something.

Yes, on few of the "big" cities (Finnish cities are nowhere to claim to 
be big - none of them has even near of million citizens, but in Finnish 
scale they (100+k citizens) are big). You can manage well with public 
transportation on a vacation, but try to work and live a bit off from 
the major courses. My trip to work every morning would take something 
like 9 hours(!), because there is no bus line from my place to the 
motorway (one could assume I'd walk that 7km - with laptop, possibly 
other hardware etc...).

I don't remember the exact numbers, but in Finland the country collects 
much more taxes from the traffic than returns there.

So do we, after some limit (gifts between 0-limit are taxless), but I 
can't remember how much it is.

At least as long as you agree with them.

I was thinking about that. As far as I can tell, no. NPR isn't (much) 
funded by the government (any more), and it's really composed of a bunch 
of local radio stations all joining in.  NPR is more like a supplier of 
content than a radio station owner, more like "Visa" than a bank, for 
example.

I don't know how much funding they get these days from the government, 
but I don't think it's enough that I'd call it a "government station".

We're up to $9/gallon for diesel and $9.50/gallon for petrol here in Germany 
now.

It went up to 19% here last year, but still small compared to the 96%!  That 
is a bit ridiculous.

I wouldn't like to live somewhere without mandatory car insurance, is there

In the UK you need to pay the annual "road tax", if you want to drive or 
park your vehicle on the public roads.

Plus, I assume you also get a lot more holiday per year than is usual in 
USA.  Most countries in Europe seem to have 4-6 weeks holiday per year as 
standard.

  Still not as ridiculous as in Denmark, where it is, AFAIK, 210%...

  OTOH I assume that means that if you own 2 cars you don't have to pay
twice?

  Yeah, that's quite cool. And moreover, by law you get an increased salary
during your holiday here.

Hmmm, looking back to when I used to visit Denmark a lot, maybe that 
explains why there were so many old cars on the roads?  So really, a car 
that costs €20k here in Germany, would be more like €40k in Finland, and 
€60k in Denmark.  Wow.

Nope, it's per vehicle, not per person, and ranges from £0 up to £400 
depending on how polluting the vehicle is.

  And it's not like you could just go to Germany, buy a car and bring it
to Finland. You'll have to pay the 96% of tax when you bring the car, so
no such luck...

Yeh I guessed as much.

I assume you're allowed foreign registered cars there for a certain amount 
of time, it's 6 months here I think.  You could just replace your car in 
Germany every 6 months, although I'm sure they thought of that already and 
made it illegal.

The car manufacturers sell cars cheaper to countries with higher taxes 
to compensate the difference. It doesn't remove the difference, though, 
just makes it a bit smaller.

But a good example: Audi A4 2.0TDI FWD with Business pack and no other 
extra equipment makes ~40k€ here.

If the car is used (IIRC 6+months old), you'll get discount from the tax 
and it's not *that* much anymore (it still is much, just not *that* much).

Nnnope, a Finnish person ain't allowed to drive foreign-registered car 
in Finland. It wasn't so long ago when the news had a great story about 
some Estonian guy with a Finnish wife/gf - she moved his Porsche for 10m 
oslt and Finland started to demand them to pay cartax (that 96%) of that 
Porsche.

Reminds me of a riddle my late father used to tell

"Why is it wherefore the mouse doth rotate?"
"Because the higher the fewer; hence the word rhubarb"

I occasionally wish I'd been able to get a hand on _his_ stash :-)

I've got them on DVD, ought to watch them again. :)

At a technical tradeshow with a bunch of friends who take turns manning 
one of the booths, just came out from having breakfast and was carrying a 
banana with me.  One of my friends - Shaun (bloke from your part of the 
world) - had been making jokes about goldfish and 5 second memories all 
morning.  I walked up to him and asked something, and he responded with 
"5 second goldfish" (which I took to mean he didn't remember the 
answer).  So I asked him "Banana?" and offered him the banana.  He took 
it, peeled it, and ate it.

In retrospect, it probably was funnier if you were there.

He speaks at this particular tradeshow regularly as well - well known for 
having told one audience he had an experimental pacemaker that was 
sensitive to the RF transmitted by mobile phones.  Got a good laugh at 
the time he said that.

*First* time during the session that someone's phone rang, he yelled out, 
clutched his chest, and dropped to the stage.  People thought he was 
joking, so they laughed - but he *didn't get up* right away.  He waited 
until he started hearing the odd murmur of "gee, maybe he wasn't 
kidding?" - then he got up and everyone had a good laugh over it.  He 
fell so quickly, he nearly fell off the stage....

The guy he was presenting with - a mutual friend from Aaland - said that 
when he dropped, a ton of people in the session *immediately* switched 
their phones off.

He's tried to plan things ahead of time, but it just never seems to 
work.  Only when it's improved does he seem to hit something that works.  
And while it *sounds* like it might've scared people in the audience, 
he's well known in his field for being a bit of a clown.

He also makes an *excellent* chili. :-)

Ke-wrist, Someone did that to me once but it involved acid and bad trips Ho, ho,
ho!

Strange, as you get older these jokes seem less funny.

I actually heard one about someone pretending to have a heart attack and one
kind soul punched him on the heart in preparation to giving him CPR.

I s'pose that could happen.  He's not a spring chicken, though.

Yeah, I think that might've been a concern if he hadn't been on a stage.  
I think that separation from the audience helped avoid something like 
that - though kinda surprising nobody called 911....

<g>  We have a party at my house each year (the show is in town) after 
the show's done, and he usually cooks for us.  He's taken a class in 
Oxaca recently (and going to take another this October), so it evolves a

to the UK, and that's how it got started - he made it for dinner one

I hear stories here all the time of Americans coming over, picking up their 
shiny new BMW from the factory, driving it to some shipping agent and then 
flying home again.  Apparently it means they can avoid some tax in the US 
because it's not counted as a brand new car when it enters the country.

Hehe, that really is strict then.  But I guess if you have to enforce that 
96% tax, you can't afford to leave open any loopholes.

List price is 28k€ here, couldn't see any reference to a business pack, but 
I guess it can't be much more than 2k.

I enjoyed reading "Soon I will be Invincible" which on the very first page

I think we should all be keeping a much closer eye on Stephen Hawking.

That's something our lot are doing at the moment, pushing everyone to fill

Due to some of the strikes here unleaded blipped up to £1.99/litre which

17.5% standard VAT here on new cars.

Supposedly here it goes towards the upkeep of the road and the licencing

Hmm more specific here - tax is only on devices that can play programmes

security camera you don't need a TV licence for it.

So I think we may come to the conclusion: Finland != US.

Business pack costs 1k€ here, and inholds equipment for something like 
4-5k€ (cruise, climate control, xenons, leather steering wheel,

Not that he doesn't like a pint or a glass (or three) of wine when the

I think the phrase "young at heart" applies - but yes, hoping for a good 
long life for him.

Here in the US, it wouldn't have been much.  I think the company would 
probably have covered it.  But also, there is perhaps an irony that 
people may not have dialed for fear of causing more harm. ;-)

Yeah; I'm pretty sure I spelt the name wrong (or as Shaun would say, 
"wrongly".)  Good Mexican food is actually quite bland - the hot stuff 
tends to be Tex-Mex instead.  I spent a couple weeks in Mexico back in 
the early 80's and *really* liked the food I had there.  There's a couple 
places in Salt Lake City that do good Mexican food as well, might have to 
track some down for lunch today.  Mmmm...

And it's very easy to lose practice. I used to be good at maths at school.
Now (like 2 years later), I sometimes take a few seconds to solve those
silly "6+7" anti-spam tests. Probably I wouldn't take too much time to get
my brain in practice again, but...

Indeed there is.  It is a useful operation in abstract algebra, 
particularly in extending sets of numbers so that they contain elements 
with useful algebraic properties.  For instance, if you consider 
polynomials over the real numbers modulo X^2-1, you get the same 
structure as the complex numbers (you can do a similar thing for 
quaternions).

In terms of real-world uses, iirc the polynomial modulus is valuable in 
in information coding.  For example modular multiplication of 
polynomials is a step in the AES cypher and a CRC checksum is 
essentially a polynomial modulus.

Ooo...

Aren't quaternions non-associative?

...and *this* is why I can't implement AES or CRC.

Non-commutative you mean, but yes.  The quaternion representation using 
modular polynomials considers polynomials of two variables (x and y) and 
real coefficients where multiplication between x and y is 
non-commutative.  So the polynomials inherit their non-commutativity 
from their variables.

Note that it's not actually important to say what sorts of numbers x and 
y would actually represent -- we're just dealing with polynomials in 
their purest form, where *all* we know about x and y are they have 
operators like addition, subtraction, and multiplication which satisfy a 
few basic mathematical properties:

> ...and *this* is why I can't implement AES or CRC.

It's not so difficult as you might think, it's just takes some getting 
used to the math.  If you're interested in the implementation rather 
than the math end of things, Wikipedia has a typically verbose article 
on the subject: http://en.wikipedia.org/wiki/Computation_of_CRC

There's also some C code dealing with the polynomials used in AES at the 
bottom of this page: http://en.wikipedia.org/wiki/Finite_field_arithmetic


Also forgot to mention that (if I recall correctly) ideas related to 
this play an important role in some of the operations in computer 
algebra systems.

Oh. Maybe I'm thinking of hypercomplex numbers then? I recall that it's 
not possible to generalise the complex field to 3 or 4 dimensions 
(although I have no idea why), so all the generalisations people have 
come up with fail to be fields.

By complete coincidence, I spent my afternoon today reading about magmas 
and groups and rings and quasigroups and semigroups and groupoids and 
rings and skew rings and splitting fields and fields of factors and 
polynomial rings and that whole zoo of other things... Apparently 
"vector field" doesn't mean what you'd expect at all! :-D

I've spent a while looking at group theory. It's not "hard", it's just 
that there are lots and lots of terms to learn, mostly with unintuitive 
names, and the whole system of groups constructed from groups 
constructed from groups gets confusing quite fast. Similarly, the stuff 
with rings and fields and so forth isn't "hard", there's just lots of 
stuff to remember...

Mathematica directly uses the commutivity and associativity of various 
operators, not to mention distributivity. Indeed there are built-in 
methods for telling Mathematica that your new function is associative 
and/or commutative. (Distributive requires explicit transformation rules...)

Yeah, once you get used to it it's not to bad.  I think that proving 
things in it is a bit trickier though, as it seems to involve deep leaps 
of logical intuition more than other areas such as analysis.  It's sort 
of fun like that though, as you can actually do interesting math without 
having to acquire a ton of background knowledge.

I was specifically thinking of the use of polynomials ideals in Gröbner 
bases (a useful took for computer algebra systems), but indeed being 
careful about how you deal with the basic algebraic properties like 
commutativity and associativity is more fundamental to such programs.

And I've yet to figure out how to solve t out of

(X0 + Xd * t - Xc)^2 + (Y0 + Yd * t - Yc)^2 + (Z0 + Zd * t - Zc)^2 = Sr^2
