But some programs still use 32-bit integers to store or retrieve the
free or total space on a hard disk, so it makes sense to keep your
partitions under 2GB, if you don't want to see messages like "2MB needed
to install, -283MB free). :)

Frederik,

 - But some programs still use 32-bit integers to store or retrieve the
 - free or total space on a hard disk, so it makes sense to keep your
 - partitions under 2GB, if you don't want to see messages like "2MB needed
 - to install, -283MB free).

Unless you have less than 2G free anyway. :-)  Partitioning is really a
kludge.  What you want is to be able to use your hard drive to store data,
without having to decide ahead of time how big the various compartments in
it need to be.

The FAT size is bigger for FAT32, yes, so you lose some space there.  But
my C drive, which is 1.2G, has 7900 files on it.  With FAT16, I'd waste on
average 16K for each file.  That works out to be 126 *megs* of wasted
space.  With FAT32, each file wastes only 2K on average, resulting in less
than 16M of wasted space.  That's a savings of over 100M, and there's no
way the FAT in FAT32 is 100M. :-)

IMO, FAT32 was long overdue.  It's not really any less safe than FAT16,
it's more efficient at using hard drive space, so why do people get so hung
up about having a lot of partitions?  I think it's because you're *used* to
having partitions, and having one big filing cabinet scares you. :-)

I also have not had any problem running Fractint on Windows 95.  No
rebooting necessary.  The image is trashed if I try to toggle between
windows, so I don't.  It hadn't occurred to me to try until I subscribed
to this list.  I like to watch my fractals get born and it seldom takes
so long that I feel I should be occupying myself with another
application.

I think I'll have to start sleeping a lot less to get maximum benefit
and enjoyment from this list.  I just can't keep up!  <g>

Maybe you're right :)

Anyway, i just don't use fat32 cause it isn't compatible with my NT and

Hi,
Does anyone know if such a thing as a criswell structure exists
(theoretically or tangibly)? It is a sort of improvement on a Dyson sphere
that happens to house the Fractal World in David Brin's Heaven's Reach.

Might as well work from the nice, clean XWindows source for this- I don't
think anyone will want the DOS features on a massively-parallel box! I
imagine that our original messager has considerable experience doing
ports to his box; given the source code, he might want to undertake the

Subject: (fractint) Mandelbrot Fleur par

I recently had my access to the internet cut off for 36 hours, so I had
plenty of time to play with Fractint. I was trying to explain to my roommate
WHY I like this program, and why I and others spend hours generating pretty
pictures.

Personally, I do it for Exploration. I love starting with someone else par
and then zooming in/out and moving around just to see what's there. Some
people like to Train Fractals, by making formulas that force the fractals to
do what they want them to do. Others like to Color fractals. Give them a
image and they will find the perfect colors to bring out all the beauty in a
fractal.

I'm sure that most people probably start as Explorers, and then become
either Trainers or Colorers, or maybe even both. Whatever the reason for it,
Fractinters (people who play with fractals) seem to enjoy the long hours of
waiting for glorious beauty to unfold in front of their eyes.

Below is my latest discovery. Based on a par from the May postings of
RParracho.

Actually a friend of ours migrated from a FAT16 W95
installation to a FAT32 W95b installation. He reported
that under FAT32 drive access speed and transfer speed
went down 10-15%.

I'm still miffed that W95 doesn't support the NTFS format
... Far more efficient with disk space than FAT32 ...
But, hey this is Microsoft we're talking about! <G>

And in NTFS, each file would waste 256 *bytes* at most!

Same in ext2fs, and it's likely that a lot more Win95 users have Linux
on their disks already than NT.  There's a read-only ext2fs driver
for Win95 already; it's not read/write yet.

And, of course, since it's Linux, you can do something about it -- with
NTFS, you're out of luck.

The June 18th issue of Electronic Design News has a good article on
fractal compression.  It is reproduced on the web at:

http://www.ednmag.com/reg/1998/061898/13df_01.cfm

It also has an addendum with some fractint images of mine at:

Does anybody out there know where I can get a copy of the old Fractal

Subject: (fractint) Improved 4-in-1 Mset Formula

comment {
This formula is an improved version of my Four_Mandels formula.
The improvement is that this version allows passes=t, which can
result in quite a speedup when there are significant areas of
high iteration counts (like baby 'Brots).  As in the earlier
version, the images can not be interrupted with any keystrokes
except for possibly the Tab key.

The two pars included are the same (except for a small change
in the colors) as the first two pars included with the original
formula.

I know that I've made an indecently long formula even longer,
but I think it was worth it.  Comments welcome.
