This is getting too physical - I was solving such problems during my PhD in spintronic materials.

LOL!  I am always interested in the applied and the physical...

I've always been amused (and appalled) at the inability of technical systems to handle white space.

Are you familiar with the new features in C++2000?

Mr Bloom moved forward, raising his troubled eyes. Think no more about that. After one. Timeball on the ballastoffice is down. Dunsink time. Fascinating little book that is of sir Robert Ball's. Parallax. I never exactly understood. There's a priest. Could ask him. Par it's Greek: parallel, parallax. Met him pike hoses she called it till I told her about the transmigration. O rocks!

Continuous or discrete?

Well, as you probably know:
"There are two main types of errors that may affect discrete Fourier transforms: aliasing and leakage."

So if we are concerned at all about false translations of power falling in some frequency range outside the range, or smearing of power across the frequency spectrum, then better go with continuous FFT.

Girl power is bad enough without these kinds of problems!

Another consideration is that "In general, the discrete Fourier transform of a real sequence of numbers will be a sequence of complex numbers of the same length."

We have seen around here that complex numbers can cause plenty of trouble on their own!  :D

I think what is called for is a discreet inverse Fourier transform operating on male fantasies about the complex nature of girls and turning them real.

Code share: You buy a ticket for a decent airline and then they put you on American Airlines. And the AA employee, with a straight face, calls it an upgrade! Which leads on to...

Free speech: Mostly in favour, obvs. But in the US it extends to lying to customers.

too much bable, come on, just

yes that is for 45 minutes!!

alternatively shut up and write up and do calculations for 22.5 minutes

many years ago, I had an argument with british airways about code share. I was booked on a flight from north america to the UK, which BA cancelled and told me I'd have to take another BA flight to a different UK city in about 6 hours then a bus back to the airport I was supposed to go to. This happened when I got to the airport and the departure sign was flashing a message to go see the agent, First they told me it was my own fault because I didn't confirm the flight, which was a lie on multiple levels as I'd actually called a couple of days earlier to make sure my vegetarian meal was in the system (and every time I've ever called an airline to confirm a flight, the reaction was always, why the hell are you wasting our time doing this). Then they generously gave me a $5 food voucher to tide me over the 6 hours in the airport, which would buy a coffee and not much more. I noticed a flight in the board in a couple of hours with a BA number and another number and asked whether I could go on that instead of spending all that time in the airport. They said, it's not a BA flight, its a (whatever it was) flight, and I said "you have a codeshare agreement." Which was met by stony silence and I ended up spending many hours in the airport followed by several hours in a bus at the other end Collector Posts: 3631 Joined: August 21st, 2001, 12:37 pm ### Re: Your rants here ppauper wrote: Paul wrote: Code share: You buy a ticket for a decent airline and then they put you on American Airlines.
