Again, not true; I have it set up on an RSS feed, so every time you post,
I see it. I may not comment, but that doesn't mean I'm not reading it.
I've told you this before, maybe it'll stick this time. ;)

And, crossing over from another thread, it's clear that even when someone
provides an owner's manual for something as complex as a car, and there are
features in the car that are completely new to the user, it's obvious that
the user *still* doesn't read the owner's manual. ;-)
The car won't shut off just because the key leaves. The dashboard screams, tho.

nobody reads because you keep blogging about dancing instead of
interesting stuff like this? ;)

isn't it the same for everything else? Like... music?
They are awful, but still technically excelent.
my point is even games these days look better than Star Wars back
then... :-)

We rented a Prius for our recent vacation, and I wondered about this
myself - but not enough to throw the fobs out the window while going down
the freeway. ;)
I also thought it was funny (and always have) that the rental agencies
put both keys (or fobs, in the case of the Prius) on the same keyring and
you can't take either off the ring.
"If only I had a spare key - oh, I do, and it's locked inside the car
with the other one". ;)

Wouldn't that mean that everybody within a 30-meter radius of my car can
illegally pick up the same signals?
Also, would the fact that my car's aerial is missing be a problem?

Probably not.

Hmm.. Good point, but would make auto theft rather easy. Not much the

while the owner is distracted.

Right... Remember when MP3 came out, computing power wasn't really up to
task, either. I remember it took hours to encode a single song.

Mine plays MP3's and has an AUX jack.... I mostly use my Zune, nowadays,
mostly because it's a PITA to burn new CD's when my musical whim
changes. I wish it had an SD or CF port. Also, it tends to be a bit
finicky when it comes to playing MP3's that have been ID3 tagged in a
weird way.

Maybe ... Though it will continue on more as CD-R than as pressed CD's.
DVD and Blu-Ray will continue, though.

Right. I don't like the idea of a machine determining whether I get a
ticket or not. The machine can't weigh the circumstances, or let a
first-time offender slide. The machine treats everyone exactly the same,
regardless of their situation or offense record.
Now, you could say that's fairness in the most absolute sense, but,
sometimes its best to allow a human being to intervene.

Well, we now have laser diodes that can work at several wavelengths now,
so ... we're not far off. Before it just wasn't feasible. But yes, the
beams can cross, and signals can be multiplexed by wavelength.

You're aware that steel *is* an alloy, right? ;-)

I don't know about other cars, but mine seems to only work if you're
within a few feet of the driver's seat. Even if you're getting something
out of the boot, if the keys are in your pocket, the engine won't start.
It's apparently that accurate.
> Oh, it can tell if the key is inside or outside the car?
Apparently. Doesn't make any sense to me, but hey...

The safety issues are one thing. The sheer inefficiency of
heavier-than-air flight is another...

Decoding is faster than encoding. For MP3 and many other codecs.
Generally encoding requires you to transform the input stream and apply
some kind of psychological model to decide which data has highest
priority, and then perform constraint-solving to cram as much of the
high priority data in as you've got room for. To decode, you more or
less just execute the instructions you're given. A bit like the way
executing a compiled program is way easier than compiling it in the
first place. ;-)

It's not uncommon for stand-alone players to be real picky about
technical details of encoded media. I've seen MP3 players that choke if
you use variable bitrates, or bitrates above or below a certain
threshold, or whatever.

Last time I checked, HMV was still selling pressed CDs by the truckload. ;-)

I remember back in the days of Windows 3.1 we had a hardware card to do jpeg
compression. It was faster to ship a bunch of raw images over the net to a
PC running a bat file in a loop to compress them and pull them back (over
NFS) than it was to compress them on the sparcstation where they were generated.
> I mostly use my Zune, nowadays,
How do you like that, UI-wise?
>> It's a simple idea, but in practise it doesn't work like it's supposed to.
I think it's more "in practice it doesn't work like people claimed they
wanted it to work." It could work just fine if people wanted it to, but
the folks in charge don't want it to only catch the flagrant violators.
> Now, you could say that's fairness in the most absolute sense, but,

In the USA, the police are supposed to look at the picture and all and make
the decision based on all those factors. Nothing is *supposed* to go out
automatically without review.
Then they figured out they could make it a "fee" rather than an actual
ticket you might be able to fight in court.

And it still has to interact when it gets to the other end.

Maybe not 30 metres, but yes, it is possible that others might be able to
receive it. So? It's a legal device used for a legal purpose.
> Also, would the fact that my car's aerial is missing be a problem?
No, because the aerial isn't the only receiver - the cable to the aerial
also is capable of receiving the signal just as well.
