Why don't the CPU and hardware manuals answer the
question? If you go to a much lower level, then you
are into electrical engineering.
Are you trying to figure out low-level semi-conductor
devices, bi-polar junctions, MOSFETs and associated
interactions? How to bias a transistor junction?
This doesn't look like a simple question.

Actually, -Os generally generates faster code in than -O2 in
egcs-1.1.2 on x86. That probably won't be true in 1.2/gcc 2.95.
It's not less aggressive, it just picks optimizations to minimize
memory usage rather than time usage. A lot of that is
eliminating unrolling &tc, but there's more to it than that
(at least in gcc 2.95). The speed gains of -Os in 1.1.2 are
probably from better cache usage.

Vladimir, are you really *that* clueless? Do you seriously imply
that work here is done without design? Sigh... Look, there are several
criterions that should be met to get, erm, a positive attention:
1) Design document should state the possible ways to achieve the
goals. Otherwise it's a wishlist and nothing more.
2) Use the terms that have a well-defined technical meaning. It's a
basic decency requirement.
3) Provide at least some analysis of the costs and benefits.
Proof-of-concept implementations count.
4) Avoid buzzwords. If you really have to use one, make sure that
you had clearly defined its meaning.
5) Avoid demagogy. Handwaving is ages-old and will not deceive anyone
who is technically able to help with implementation.
6) If you are saying that property FOO-P is required give a definitive
way to verify FOO-P(implementation). E.g. "for any moment of time the set of
filesystem methods under execution must satisfy the following conditions:
a) any pair should be commutative and b) every filesystem object should be
affected by at most one of those methods" is OK; "filesystem should be OO"
isn't.
7) Describe how your design is different from the existing ones.
This analysis should meet the criterions above.
8) Describe the problems you are trying to solve. Ditto.
Lacking that your text is not a design document; it's a sales pitch.
Not too wise thing if you have nothing for *immediate* sale. If you are
declaring your intentions - fine, you could declare them clearer, but that's
your business, after all. If you are looking for somebody who would invest
his time and efforts in your project - have enough respect to potential
inve^H^H^H^Hco-workers and take time to produce a technically sound document.
You have failed on *all* those points. In any software house you
would be politely pointed to the door and you essay would go into the
round filing cabinet, believe me (or just try yourself).
Having a clean design is *very* good thing. It is needed and even
if it is not published on USENET it is done in any serious project. Otherwise
the code fall apart under onslaught of tweaks and features. The problem being:
your text doesn't come anywhere near the description of clean design. And
you don't have any proof-of-concept implementation we could analise and
fill the gaps in your text; moreover, you claim that you are above doing
such things. Well, best wishes and don't let the door hit your ass on the
way out. Come back when you will have something better than vague handwaving.
Clear design with decent analysis, working code, something. Right now you
demonstrated a nice Rorschachesque and nothing more. Sorry.

Why object to rewards you know you earned them....?
Anyway, software tax is intelligence, but being an idiot is nuts. I think
that linux IS proof of a collective socialism, but I think it's hard for
someone to setup companies like RedHat !!
And I can't give support all over the world...
I would hope to have a uncrackable binary trial version (like VMWare,
though I some somthing about a crack, still I will buy it !!) to let
companies pay for it !!.
The trial version for instance could be compiled in a way that the object
handling interface (the API for custom and other modules) is ommited, so
the binary can ONLY administer availlable objects !
Anyway, I am not a socialist. I use linux, not to fight the power, but
because it is in my own benefit !
I now use kdevelop. That's a great program. I also have Windows NT
workstations and stuff, and sunday I get a Sparc with Solaris (can I dual
boot it to linux ??) but I also have Netware servers, NT5 beta 3 server
and working on a minix and bsd 3.1 installation.
There is so much to learn...
But I don't agree in the public hatred against M$. (though I read some
great stuff about M$ blackmailing Compaq NOT to pre-install OS/2). I mean,
what about our great 'friend' IBM.
Do you know why award BIOS and all exist ?? Because IBM would not share
information about BIOS on PC's, so companies had to reverse engineer them.
Eventually some provided for a range of clone-fabricants.
And do you know WHY Corell wants linux ??
To sell it's Office products (though I wonder why they support Wine, who
cares after seeing KDE anyway. And I mean that !!).
Anyway, learn a lesson. Those guys paying ALREADY have companies !! And I
want to build idealistic software and for that I need resources.
So I want to make money to make it easier for me to create...
I don't know, who cares if companies pay me anyway ??
I aim at Windows NT users, who want to use a linux machine for email,
routing, proxy, http, etc. but gave up after 4 hours messing in the
sendmail configuration (let's by a fast server and use Exchange, we got
more work to do).
Instead, they CAN use that P75 with 16 MB memory, because my LMA client
has a terrific Win32 GUI that configures it perfect !!
They than EARNED money (you know, less cost of ownership), and then I am
entiteld to a piece of the pie !!
If not, you're a 'rebel', partly responsible for the current state of the
human race (at least unrealistic and unmeditated)...
Tsjakka!
Selious, the DragonSlayer !

Unfortunately (IMO), in this culture "free" often means "not free to use
with other software unless it is licenced under a FSF licence". Or it
means "whatever RMS says it means". People who haven't read the fine
print often think it means something much different than the author did.
I agree "free" is often used correctly for things that are nearly free.
I strongly disagree that GPLed or LGPLed software is nearly free. Its
key feature is that it and its derivatives will remain open. It may be
a good thing to keep the software propretary (look it up if you think
I've misused that word) and use a restrictive licence like GPL so the
many people who write closed software can't use it, but it is NOT a good
thing to use deceptive terms to describe your software.
I used to wonder why copyright statements said "this is free
software..." instead of just saying "this is licenced under the GPL..",
because "free software" is so subject to confusion, but now I believe
the choice was quite carefully made. A marketing ploy worthy of the
guy who sold me that Yugo.

I never proposed it as a software engineering document. As an
anthropological investigation of how the online community works
it's the best I've seen. It's not perfect, but it is about the
only serious attempt to study how online development works that
I've seen.
As for your categorization of the respondents in this thread as
uneducated and inexperienced, it's not accurate. Everyone from
that sort to people with technical postgraduate degrees and 20
years of work experience has been trying to get Vladimir to at
least consider getting educated on the topic. Some have
even worked with HCI departments and contractors developing advanced
data visualization environments and interesting, specialized
UIs.
Vladimir does have good intuitions and I think he would really
be interested in HCI and could do quite well at it. But his
designing a UI is like a smart high-school kid with a couple
of C texts trying to design a new programming language -- possible,
but if you take a few PL and logic theory courses you'll have a
lot better chance at avoiding the traps others have blundered
into and building on their successes.

Third, I have read IO-APIC.txt, and I understood that the 'black and white
lists' are on the kernel code. I was looking for the file (where it could be?),
and I found it (it was easy). The file is 'linux/arch/i386/kernel/io_apic.c',
and you can find the next two declarations on it:
struct ioapic_list_entry __initdata ioapic_whitelist [] = {
{ "INTEL " , "PR440FX " },
{ "INTEL " , "82440FX " },
{ "AIR " , "KDI " },
{ 0 , 0 }
};
struct ioapic_list_entry __initdata ioapic_blacklist [] = {
{ "OEM00000" , "PROD00000000" },
{ 0 , 0 }
};
This extracted text is from the file you can find on the 2.3.5 kernel. As you
can see, there are only a few motherboards on both lists, so I think a) many
motherboards are giving any of these entries or b) people is using Linux SMP
kernel but they are not reporting success stories to SMP developers.
Thanks again,
Jos� Mar�a

So far most of these only deal with configuring one program's configuration
at a time, ignoring the overlapping relationships of machines, users,
groups, mailing lists, etc. Ganymede (http://www.arlut.utexas.edu/gash2/)
looks like something a bit smarter about that, but probably overkill
for small sites. Has anyone with a few hundred users or less tried
it?

Well I found an intersting thing about the gigabyte GA-6BXC motherboard.
If you have a revision 1.7 motherboard (not bios), then it will NOT boot
off of a floppy. !.8 will. I am going to try to update the bios to see
if this fixes it (or breaks everything else ;) ).
