Shark!
Sunday, January 21st, 2007A shark, a lot of little fish, and a few trees in one picture:

Taken at “Atlantis”, Paradise Island, The Bahamas.
Hungry (or Greedy)?
Thursday, November 16th, 2006My company is hiring. Note, that
the jobs have nothing to do with open software and that we are rather
picky.
Home Repair
Wednesday, September 13th, 2006It looks like every geographic area has its own version of duct tape
in the used-far-outside-its-intended-domain sense when it comes to
home repair.
In the neighbourhood of Home.1 it is paint. There is nothing that
cannot be fixed with an extra coat of paint. Door is scratched?
Paint it! Floor is not level? Paint it! Roof leaks? Paint it!
Window broken? That has not actually happened to me, but I am sure it
will get painted.
Near Home.2, things are different. The material of choice is sealant
of the type properly used for sealing around the tub. It is
everywhere. Cracked marble? Seal it! Lose tile? Seal it! Crack
between floor board and floor? Seal it! Need to make wall paper
stick at floor board? Seal it!
It could be worse, I guess. Maybe some places use floor wax or drain
opener to get through the day.
A public service announcement: anyone who suggests going furniture
shopping to me in the near future (i.e., months if not years) risks
getting whacked over the head with a corner sofa in his or her choice
of beige or red fine, Italian leather.
Quantum Traffic
Tuesday, September 12th, 2006In classical multi-lane traffic, cars travel in one lane or
another. When a driver wants to change to a different lane, he or she
does so quickly and order is maintained. However, in quantum
multi-lane traffic, it is quite common to observe a car that is, say,
70% in one lane and 30% in the next. The precise meaning of such a
state is unclear, probably ranging from “I think I want to be in this
lane, but I might need this other one later” to “My ego is too big for
just one lane.” Either way, it is rather unnerving for classically
trained drivers. You can find quantum multi-lane traffic all
over Beijing.
Speaking of Beijing traffic, one cannot help marvel at the city-wise
art show put on display for drivers in the city. I refer here to what
looks similar to the traffic lights you can find in most western
cities. It is only looks that are alike, though, because the Beijing
ones seem to have no traffic regulating function. Instead you can
imagine drivers admire yet another masterpiece from the artist’s “red”
period while proceeding at full throttle.
(To be fair, I’m sure there are rules. Some of them even written down, but clearly they are different from what I am used to. Then
again, I find the Pittsburgh left turns scary.)
IP-over-DNS
Thursday, September 7th, 2006I’ve been in Beijing for a while. This is the first of a series of
blog entries relating to that trip.
Why does it cost $10 to get internet connection for one day at an
airport like JFK? The cost behind it cannot be much more than a DSL
line at $30 per month and renting a closet at the airport.
One would assume that, if allowed, any of the stores present could
easily put up a competing service. They probably need the internet
connection or something similar for credit card authorization anyway.
But clearly competition is not working here as prices have not come
down from the skies. I would assume that there is a local monopoly in
place. I can see good reasons for imposing such a thing in an
airport. After all you do not want too much unrelated radio traffic
going on when you have a fleet of airplanes to handle, but couldn’t
they at least have made it a duopoly? Or put price limits on the
monopoly?
In the meantime, would it be unethical to set up a ip-over-dns gateway?
They seem to allow dns lookups for free.
Shoes
Tuesday, January 17th, 2006I was flying back from The Bahamas yesterday and airport security[*]
decided to check out my shoes three times. I know they
might be a bit smelly and big enough to hide a Hummer, but why
not just check them thoroughly once?
But I was good. I even resisted the temptation of handing over
my three-year old for them to hold while I took off my shoes.
Someone would have gotten kicked, slapped, clawed, and/or worse.
He is cute, but he takes no prisoners.
[*] The use of the term “security” to describe people in airports is not to
be taken as an indication that their presence or function improves
safety.
Utility Functions
Friday, August 12th, 2005Dom,
it is probably not that they are being inefficient or behaving illogically. It is more like that they are optimizing a utility
function somewhat different from the one you would naïvely expect.
(A mathematician takes a walk and comes by a house on fire; he calls
the fire department and they come and put out the fire. The next
day he comes by a house that is not on fire; he sets it on fire and
walks on after thus having reduced the problem to a previously solved
one.)
Beating the Bush
Tuesday, July 19th, 2005It looks like someone took Mr. Bush’s word to the bank and just like
a bad check, it bounced.
Again.
Nat is Crazy
Friday, July 15th, 2005Nat, that is crazy.
You are not exactly 25 years old anymore.
Ok, I have done worse, i.e., I have done 200 miles a couple of times.
That takes about 12 hours, all breaks included. Some things you ought
to know in advance:
- Your route looks somewhat dangerous, traffic-wise. Wear something
with screaming colours. - Your behind will be as sore as your jaw was recently.
- Your ability to control various muscles you did not even know you
had will be temporarily affected. Do not drive a car yourself for a day. - If you get wet, say around Quincy, the trip is not going to be
any fun. You will end up with a mixture of water and road dirt thrown from your own wheels all over yourself. It will make an unpleasant sound on your teeth. (Been there, done that.)
