Still the file to change these things manually exists (and is used
often), and is called /etc/X11/XF86Config

First of all I deleted some NG's from your list, make a choice, and post
there, it doesn't really matter, lots of people monitor more than one
group anyway.
This result stil shows the reason of your problem, The easiest solution
now, is to use DOS FDISK to create a new partition, that does start/end
at a cylinder boundary (DOS FDISK will do this for you) Then copy all
data from the old partition to the new partition, and remove the current
partition. after you've done that, you can use PM to move that partition
you've just created and add new partitions.
Unfortunately PM is very strict on what it allows in partition tables,
therefor it cannot handle partition tables that aren't compliant to
these strict rules (one of them is that partitions must start/end at
cylinder boundaries.

I don't know for sure (not having been around Linux from the beginning),
but it was probably the ACK (Amsterdam Compiler Kit) C compiler that
came with Minix that was _first_ used to compile the Linux kernel.

Actually, the root of _this_ OS tree was hand coded in PDP-7 assembler,
and cross assembled on (IIRC) a GE system (running GECOS). You might
want to check out Lucent Technologies "History of Unix" website for the
gory details. Once the first Unix was written and running, Bell Labs
wrote a compiler based on BCPL, then rewrote most of the Unix OS in the
language compiled by this compiler. The results became the seed for the
Unix (and Linux) we know, and the language which evolved into ISO
standard C with Posix extensions.

Hi there,
I just scored a free Intel Pocket PC Camera (USB interface). I have
installed "gphoto-0.4.3-0_helix_1.i386.rpm" on Redhat 6.1. However, this
camera is not listed in the compatibility list. Could someone please let
me know if they have got it to work on Redhat 6.1.
Thanks in advance.

abcde doesn't actually do the encoding. From the freshmeat entry:
abcde is a frontend to cdparanoia, wget, cd-discid, id3, and your
favorite Ogg/MP3 encoder (Oggenc is the default). It grabs an entire CD
and converts each track to Ogg/MP3, then comments or ID3-tags each file,
all with one command. It supports parallelization, SMP, HTTP proxies,
customizable filename organization and munging, playlist generation, and
remote distributed encoding via distmp3.
A very good piece of software.

Subject: Stack access speed
Date: Tue, 14 Nov 2000 09:52:21 GMT
Hi all:
My name is Alan and I have a question that I need some help from all
great minds in this forum.
The question are as follow:
Question:
Platform 1 = Pentium 600 ,Win NT 4.0 + SP4 , Visual C++ 6.0
Platform 2 = Pentium 600, Suse Linux 6.4 , GCC compiler 2.95.2 with
optimize flag '-O2' set.
I have programmed the following code for a small test and run it on two
different platform as stated above.
Code:
====
void STATIC_RAM_TEST()
{
unsigned long bigArray1[500];
unsigned long bigArray2[500];
unsigned long bigArray3[500];
unsigned long bigArray4[500];
unsigned long bigArray5[500];
unsigned long bigArray6[500];
unsigned long bigArray7[500];
unsigned long bigArray8[500];
unsigned long i;
for (i=0;i<500;i++) {
bigArray2[i] = bigArray1[i] + i;
bigArray3[i] = bigArray2[i] + bigArray1[i];
bigArray4[i] = bigArray3[i] + bigArray2[i];
bigArray5[i] = bigArray4[i] + bigArray3[i];
bigArray6[i] = bigArray5[i] + bigArray4[i];
bigArray7[i] = bigArray6[i] + bigArray5[i];
bigArray8[i] = bigArray7[i] + bigArray6[i];
}
}
The results is as follow:
MS Visual C++ = ~900ms
Linux with GCC = ~2000ms
We then change the declaration of these arrays to "static" and rerun
the test, the result are as follow:
MS Visual C++ = ~900ms
Linux with GCC = ~950ms
We have isolated the problem to be "access speed to locally defined
automatic arrays" i.e. stack access speed. Our arrays are typically 1
KB in size and we use lots of them in our functions. As shown above, we
ran some timing tests for simple manipulation of arrays cells and found
that arrays defined as "automatic" ran significantly slower than arrays
defined as "static". This has caused our program to crawl in certain
instances when arrays are constantly being pushed and popped from the
stack. Is there a way to configure Linux to be more efficient in this
regard, or possibly we have missed something in GCC?
Any help would be much appreciated here. Thank you for your time.
