i know that.
however too many people get it wrong. nearly everyone i know got it
wrong the first time they encountered it. this leads me to believe the
words were poorly chosen in the first place.
it'd have been much easier to say
server = display
client = application
and then use the words display and application everywhere instead of
server client. on the other hand, made up non-sense words without any
preconceived meaning would probably be just as good. you would learn
them quickly enough anyway.

You need to set the PnP stuff with isapnptools. Do: man isapnp and man
pnpdump. You do not need to make sure the settings for Linux are the same for
Windoze, as the PnP settings will set the card accordingly. Just make sure
the sound settings in the kernel match the isapnp settings - and compile the
sound as modules.

Subject: Help with bttv and tuner options for Hauppauge card
Date: Fri, 20 Aug 1999 16:05:24 GMT
Hi all
I am having trouble getting bttvgrab to work on my RH6.0 system with a
Hauppauge WinTV board. When I try to grab an image, all I get is a
blue screen or static. I suspect I haven't selected the options for
the bttv and tuner kernel modules. I'm installing the following
modules
insmod videodev
insmod i2c verbose=1 scan=1 i2c_debug=0
insmod tuner debug=0 type=6
insmod bttv radio=0 card=15
which produces the following output in the syslog.

Red Hat 6.0 is a libc6 system. This is some sort of libc5 (== gnulibc1)
compiler.
The gcc 2.8.x versions have never been well-liked by Linux. You should
use the standard version provided by Red Hat. The may package it under
the name "egcs" or "egcc" (just to confuse you).

This is probably a sign that your binutils (or dynamic loader -- some
part of the development chain, in any case) is not compatible with your
compiler binaries.

Subject: LILO for the Linux newbie. . .
Date: 20 Aug 1999 23:49:52 PDT
Reply-To: [EMAIL PROTECTED]
Hello
I'm completely new to Linux. Infact, I'm 15 years old and my father
helped me through a Linux install to my own machine. We have a small
problem though. Linux will not boot unless we put in the boot disk.
Here's the bio. . .
I have:
1 = IDE Hard Drive ~1.2 gig
2 = SCSI Hard Drives ~2.0 gig
The 2 SCSI drives are connected to a Soundblaster 16 SCSI-2 card. The
IDE HD and one SCSI HD is used for Win95 (ick!). The other SCSI is for
Linux. The SB16 SCSI-2 board DOES NOT have a boot prom, so we found a
line we could enter into LILO to find the SCSI-2 controller and boot off
the second drive. This line was:
aha152x=0x340,11,7,1,1
These were the right settings for the built-in controller and it found
both drives. So we made the second SCSI drive a "Linux native" and we
also made .2 of the IDE HD as "Linux swap". Everything was going well,
we installed everything, set up which protocals to run, etc. Then, I
forgot to set up Win95 as the thing to boot up first instead of Linux.
(sorry...I'm only native to Win95 for now.) So we rebooted the machine
and when LILO printed on the screen, all of a sudden, all these "BB"s
were popping up on the screen and kept going and it wouldn't stop until
we used Ctrl-Alt-Del. The only way to get into Linux is to use a boot
disk. Any suggestions to a Linux newbie?????? Please respond! Not
knowing the problem is very painful :-) Thanks!

This is an interesting idea. However, how do you propose going about
properly compensating each of the developers on a given project? You

about developers that contribute much more? Were I to contribute the
majority of each day to the project, I would feel a little miffed if
someone who had fixed one typo in the documentation received the same
amount of money.
I can also see this getting abused. People registering multiple
times, people submitting small changes simply to get paid the full
amount, etc.
I don't mean to discourage the idea, but it does have to work in The
Real World, and The Real World is full of Bad People.

Er, this is definitely wrong ;) one thing that was adhered to very
closely throughout the design of C++ was the dictum `you don't pay for
what you don't use'.
It *is* possible to implement MI such that you don't pay for its
overheads when it is not being used --- in fact, given the comparative
rarity of use of MI versus SI[1], it would be downright stupid to
design a compiler any other way.
And g++ is designed such that MI's overhead (minimal) is not paid when
it is not being used, and that virtual base classes' overhead
(significant) is not paid when it is not being used.
I've used MI w/o virtual bases for mixins in time-critical simulation
modelling code before. I tried a mixinless implementation first, to see
how much of a speed impact the MI involved in the mixins had. At least
in this case, the overheads due to MI were lost in the noise (and there
is always noise, especially in distributed simulations).
[1] Stroustrup describes MI as a `parachute' in that it is rarely
useful, but when it is useful it is a godsend...

No. If this is the case, then you have a *very* buggy compiler.
>From the C++ Standard (OK, from public comment draft CD2):
: 12.7 Construction and destruction [class.cdtor]
:
: 3 Member functions, including virtual functions (_class.virtual_), can
: be called during construction or destruction (_class.base.init_).
: When a virtual function is called directly or indirectly from a con-
: structor (including from the mem-initializer for a data member) or
: from a destructor, and the object to which the call applies is the
: object under construction or destruction, the function called is the
: one defined in the constructor or destructor's own class or in one of
: its bases, but not a function overriding it in a class derived from
: the constructor or destructor's class, or overriding it in one of the
: other base classes of the most derived object (_intro.object_). If
: the virtual function call uses an explicit class member access
: (_expr.ref_) and the object-expression refers to the object under con-
: struction or destruction but its type is neither the constructor or
: destructor's own class or one of its bases, the result of the call is
: undefined. [Example:
: class V {
: public:
: virtual void f();
: virtual void g();
: };
:
: class A : public virtual V {
: public:
: virtual void f();
: };
: class B : public virtual V {
: public:
: virtual void g();
: B(V*, A*);
: };
: class D : public A, B {
: public:
: virtual void f();
: virtual void g();
: D() : B((A*)this, this) { }
: };
: B::B(V* v, A* a) {
: f(); // calls V::f, not A::f
: g(); // calls B::g, not D::g
: v->g(); // v is base of B, the call is well-defined, calls B::g
: a->f(); // undefined behavior, a's type not a base of B
: }
: --end example]
Conceptually, during base construction the derived class does not
`exist' yet, and none of its data members have been initialized, so it
would make no sense whatsoever to call its virtual functions. (As the
excerpt above states, the same is true during destruction.)

Slackware's not really the best choice for a new Linux user. I'd
recommend either Caldera, Red Hat or Suse. There's not much between
them. I think Caldera's probably the easiest to setup going from the
reviews (I haven't used it), Red Hat's the most popular but is also
the most expensive when bought boxed. Suse includes more software than
you'll probably ever need, but should save you significant download
time.
