Maybe not.

In MD, they went from helmet to none and back. Here in PA, ABATE
managed to get helmet laws repealed. I'm talking cycles here. You
hit a car or big truck head on on the interstate and a helmet won't
help much. I won't mess with those links, but I don't know of anyone
getting head trauma on a bicycle.

I *do* think the friggin' adult bicyclists should stay the hell of

one of them. >-)

Now last winter I saw a thing about static setting off gas pumps

madness. same thing here, except its usually German tourists. I mean do the
math - if I travel at 100km/hr = 28m/s, and I come around a corner to find a
couple of semi-expired tourists in my lane with oncoming traffic, there is a
problem. Technically I will be in the wrong when I hit them (failure to stop
in half the clear distance) but that wont make them feel any better. and
lots of our roads are narrow and windy.

the worst ones are the cycling athletes, who think nothing of riding 4
abreast. I have done some fairly exciting braking manoeuvres to avoid
killing these twits. Perhaps the worst though was a cycle race near where I
lived in Clevedon (in a pair of geodesic domes, set in 6 acres of beautiful
native bush, high on a ridge. wow, amazing views). The start/finish line was
on Parish Line Road, which I drove down. A group of "officials" were
standing in the middle of the 100km/hr road, and didnt move as I drove up.
Fair enough about the cyclists, they had signs up etc. but these 6 guys were
just standing in the way. I screeched to a halt (barely missing them) and
politely asked them to get the fuck out of my way. are these people stupid

interesting that the Aussie study is diametrically opposed to the NZ
studies. Good that I remembered correctly.

I have long been interested in statistical results that contradict
predictions, and I remembered the AU/NZ bike helmet difference
from some studying I had done on anti-lock brakes.

One of the great things about good engineers is that they (we) tend to have
an evidence-based approach. Things that dont in practice work tend to be
avoided. If only the talentless fools we ALL have in lieu of politicians
would work the same way.

I just wrote a proposal to develop a +48Vdc 10kW IP67 power supply to
replace the telco ones we sell to our videoscreen customers. The telco ones
are fragile, and dont like long trips in trucks. The approach to date has
been a detailed operational spec, requiring kid gloves etc. Alas, no-one
ever gives it to the truck driver, so the customer experiences a high level
of field failures, which are technically their fault, and for which they
have to pay. such a solution is therefore not a solution at all, merely a
means of apportioning blame. and no use at all to the guy who drives his
screen to Christchurch, only to find it doesnt go.


In case you are interested, I posted a list of my books to abse

Speaking of signs and being in the road, on one of the same problem
roads I'm thinking of, the road crews sometimes have to go out and
pick up debris that washes of the cliff during the rains - pretty
spectacular waterfalls shooting out into the road. They don't put up
signs or use cones or flagmen. Come out of a turn and there they are
in the road.

If a utility worker pulled that shit in a real town, he'd be shut
down.

Last time I checked, non-smokers and smokers are equally likely
to die. The death rate for both groups is 100%.

You could try multiple methods all at once; crash into a gas pump
at high speed while smoking, drinking, having unsafe sex and having

A few months ago, I was driving around in my little town and a big old ugly
4WD pickup passed by me but stopped ahead of me at a red light. When the
light turned green, the truck didn't go. Then I noticed smoke pouring out
of the truck's engine compartment, and then the driver leaping out and
popping the hood. He ripped off his jacket and started beating on what
looked like a fuel fire. Unfortunatley, he was wearing a down-filled nylon
jacket. Pieces of the nylon layer vaporized (or flash-burned) every time he
hit the engine block with it, and feathers were floating downwind.

I pulled over to the curb, well out of the fire range, and walked over with
the dry-powder fire extinguiisher I keep under the driver seat of my old
Jeep. He was able to get the fire out with one good squirt.

Here are some interesting numbers.

There are over 6 billion humans alive on earth right now. That is more than
1/3 of all humans who have ever lived. Therefore, the odds are better than
1 in 3 that you will never die.

Numbers don't lie, but sometimes the interpretations do.

The best estimates for the total number of human beings

RPN is for dweebs. My mind works Algebraically.

English reads left-to-right, as does RPN. Just because you can't
think left-to-right and need crutches doesn't mean RPN isn't
goodness. Try it for a day some time. You'll never go back!

Some kid tried to tell me how RPN can even be usable. He
compared it to pencil and paper. He said, "You don't
write down 13, then add, then write down 56, then equals,
and 69. You write down 13, then you write down 56, then
you add." I said, "When I'm using the calculator, I'm
not writing stuff down. I wanna know, 39 Plus 56 equals
What? So I type 39+56= and there's the answer! Why is
it easier to do it inside-out?"

They just think differently, I guess.

I joke around about RPN being The One True path, but really, both
ways have good and bad points. There is a reason why the people
who invented equations chose [ 2 + 2 = ] instead of [ 2 2 + ].
It's a better way to write down equations.

Just because you joke around doesn't mean you're not speaking the
truth! ;-)

In addition, there is the baby duck syndrome. A baby duck imprints
on whatever it sees right after hatching and that's mommy. We all
tend to judge calculators, wordprocessors, operating systems, etc.
by comparing them to our first.

I had to train myself on RPN calculators (yes even in '73
arithmetic calculators were available). I found it amazing when
a drinking buddy (a female, btw), got interested when I made a
comment about WRPN and V42. Whe *wanted* them on her desktop
too. She's not an engineer, but appreciates RPN too.

Just as an aside... Has anyone who loves algebraic calculators
tried to program one? ...as in write the assembler code to
produce the crap? Humans and machines really do think in RPN,
whether they want to admit it or not. ;-)

I think it's pretty trivial- you just use the same setup as you would
for an RPN calculator but with another (narrow) stack for the pending
operators. Whenever the user hits open-paren or you run into a higher
precedence operator you push the intermediate value and pending
operator into the stacks. When the opposite happens you perform the
operation and drop the stack .

Humans and machines really do think in RPN, whether they want to admit it or not. ;-)

All my controller designs that I programmed in assembler over the
years have used a small proprietary fixed-point stack-based
calculation engine for the "guts". For exampel to convert a
temperature from C to F, it might do (in calculator terms) ENTER(0.9),
MULT*2, MULT ENTER(32.0) ADD For a compiler to convert from an
algebraic equation to a RPN sequence of operations is pretty trivial
using recursive functions.
