I wasn't aware either of us was trying to convince the other of any

Windows Update and ClickOnce don't count? :-)

That you'd have to put it under a name that IIS won't look at, whereas grep
has no way of knowing what files Apache won't look at. It's much easier to
say "IIS roots are stored under \HKLM\blah\yadda\*\docroot" and get all of
them than it is to parse XML with include files using grep.

And yet, every PC I've had a chance to observe is still running XP.
Now obviously I haven't been able to observe every PC in the country.
I'm sure a small minority of them are running something newer. I do know
that whenever I see a PC running a shop till or whatever, it's running
XP. (Or MS-DOS, weirdly enough...) I know that all the computers where I
work still run XP. I know that the few home PCs I've looked at are
running XP.

Most new PCs come with Win 7 now. It is after all the year of the worn
tuppence.

Active Directory uses Kerberos authentication, but by default it still
generates weak-arse LANMAN password hashes for backwards compatibility.
So it doesn't matter how strong Kerberos may or may not be, because you
can just attack LANMAN instead.
That's just one example of how backwards compatibility tends to
completely ruin any attempt at security.

True, but not for this particular reason. ;-)

My new laptop [which isn't so new now] came with Vista. I don't use it
all that often [I don't leave the house much], but it's there.
Question is, how often does the average person buy a new PC? Not very often.

Of all the reasons to move to another town "because the tills run
Windows XP" has to be one of the lamest reasons ever! :-P

There's always one. ;-)
No, seriously. I'm not saying nobody on Earth is using it. I'm sure
people are. I just said that not /many/ people are using it yet. I
imagine that will gradually change over time.

That's kind of evil. I'm not sure how somebody sitting in an interview
chair is supposed to solve a problem right there on the spot. I mean,
it's not like they can go away and look stuff up...

If I wanted to know how to live forever, I wouldn't bother posting a
question in an online forum. You know why? Because... it's...
impossible. It's not that I don't know how, it's that IT CANNOT BE DONE.
Now with software we're dealing with somewhat less absolute quantities.
I gather that if you read Linux From Scratch, it actually directs you to
where you can download the source code for an entire Linux/GNU system
and compile just the parts you want from source. YOU do the dependency
management by hand, and in theory you can alter the source code to
remove dependencies you don't want. So hypothetically it's *possible* to
work around any given distro's poor dependency management. Does that
mean I actually want to go to such extremes? Not really, no.

I still don't get how you can take megabytes of unformatted raw binary
and glean anything remotely useful from it, but hey. Apparently there's
some kind of black magic that makes this possible...

The greatest knowledge is in knowing that you know nothing.
On the other hand, if you punch a brick wall with your fist, it hurts. A
lot! Now do you assume you're just doing it wrong, and go ask an online
forum how to do it "right"? Or do you just stop punching walls? I know
which one I'd go for... I guess that makes me ignorant then.

If you try something, and it doesn't work, you can keep trying it over
and over again, or you can try something else. Which option is the most
rational?
(I guess it's a question of degree, of course. If you give up at the
first try, you'd never get anywhere. Then again, if you keep doing
something that clearly doesn't work, you're also not going to get
anywhere...)

Package managers track package dependencies. Packaging teams write those
dependencies. Sometimes their structure is a little coarse. What more is
there to learn?

IME, although the open source development model means that theoretically
anyone can contribute to improving the product, in practise this doesn't
work. It's extremely rare for submitting a bug report to actually result
in a fix. [That's assuming the problem is even strictly speaking a "bug"
and not merely a "hey, maybe if the system looked more like THIS it
might be better".] Actually contributing code is usually a practical
impossibility, for various reasons.
I'm sure somebody somewhere is committing code. But for most of us, it's
just not an option.

The irony is, I used to be the biggest Microsoft hater ever. I was used
to using AmigaOS, an operating system which ACTUALLY WORKS PROPERLY.
Compared to that, everything to come out of Redmond seemed like the
biggest pile of junk ever. And then along comes Linux. It's based on
tried and tested technology. It has powerful tools. It has uptimes
measured in decades. It's faster and more efficient. It sounded so exciting!
Of course, initially Linux was a total PITA to set up and actually use.
You needed to know all sorts of exotic technical details about your PC
in order to get it to install. Making X11 work was basically a hopeless
task.
Obviously things have improved considerably since then. I still remember
when KNOPPIX first appeared. An entire OS that you can just boot off a
CD, without configuring anything, and it just WORKS. Most of the time.
OK, sometimes. Back in the day, that was a stunning achievement. These
days *every* distro has a live CD. But once upon a time, it was really
impressive to be able to modify a distro to the point where it can be
run from a read-only filesystem small enough to fit on one CD.
(KNOPPIX itself has since gone all minimal. But there are lots of other
live CDs available now...)
I make a point of always having a few Linux live CDs around. You never
know when you're going to need to mount a Linux-formatted filesystem, or
quickly format a disk without installing an entire OS first, take a raw
drive image of something, or whatever.
Over time, however, I came to realise that Linux doesn't actually seem
to be much more efficient than Windows. That used to be one of the big
things people talked about: you can run Linux on a 283 with 16MB RAM,
and it WORKS, and it WORK WELL. Try doing that with Windows! But you
know what? It's a long time since I've seen a distro that can still do that.
There was a time when Windows used to crash constantly, PCs were barely
powerful enough to run it, configuring it was tedious and complicated,
applications would never uninstall cleanly and often wouldn't install
cleanly in the first place... and basically the entire thing just
sucked. No wonder so many people hated it!
Over time, Windows has gradually become less sucky. And I haven't used
an Amiga for a very long time, so I no longer have any truly great
software to compare it to. Linux has improved dramatically as well, of
course... The latest Ubuntu basically asks you for a username and
password, and then just *installs* itself. Next time the PC reboots, you
have a fully-functional Ubuntu install. It doesn't /get/ much simpler
than that. (Although I dread to think what happens when it goes wrong...)
Essentially, things have evolved to the point where you can compare
Windows and Linux, and see that each of them actually have merits
compared to the other. And the point we're currently arguing about is
one of them. On Windows, you just *install* stuff, and it works. Under
Linux, you try to install stuff, and mostly it just works... except when
it doesn't. And then all hell breaks lose.
I'm not saying the entire Linux system sucks. I'm saying one specific
aspect of it is annoyingly difficult. And yet, everybody is yelling at
me like I'm some noob who installed Linux, tried it for ten minutes, and
couldn't figure out what the A: drive is called now so I gave it. It's
not LIKE that AT ALL. And it irritates me when people tell me I don't
know what I'm talking about...

Right. Well knowing what the command switches are isn't going to help me

If somebody told you that the Earth is in fact flat, would you take the
time to sit down and have a rational conversation with them? Or would
you just be like "psssh, yeah RIGHT! Bye..."
Likewise, if you use a piece of software and it's clunky and awkward to
use, and somebody else is all like "it's divine and perfect and flawless
in every way, you're just using it wrong", are you likely to investigate
what they're saying?

Well, I suppose short of me spending the next 10 years using Linux all
day, there's not much we can do to resolve this particular point.

Like I said, the normal way to configure Linux applications is via
exiting textual configuration files. I never said it was "impossible" to
do it any other way. I just said that that is the main cultural focus.
Which is different from the cultural focus on Windows. That's all I was
trying to say. Sheesh...

OK. So I've actually heard of one of the items on that list. I'll give
you that.

My spider-sense says something about Windows Media Player... I guess I'd
have to spend a few hours Googling it to find the real answer.

I would if I respected the person and their opinions. In fact I have
done so. I even installed Linux at one time but never got round to
asking anyone to help me. *Mea culpa* :-[
