I made the arguable "mistake" of formatting a 64MB CompactFlash card
with an ext2 filesystem.
Which is pretty slick, in some ways, but which has the unfortunate
effect of rendering it inaccessable by anything that expects it to
have the traditional FAT filesystem.
If I hook up the flash card to a laptop running Windows, it has the
entirely entertaining effect of causing it to detect it, and then
detect that it cannot do anything with it, thus leading the computer
to reboot. [Then it detects the card again, tries to read it,
--> reboot. Repeat as needed...]
fdformat does not seem to cope well with it; is there some other
utility I should be looking to?

Stability, power and flexibility. There is MUCH free
scientific/mathematical software for Linux
(http://SAL.KachinaTech.COM/sal1.shtml), including a Matlab workalike
called "Octave" (http://www.che.wisc.edu/octave/).

Yes. Almost all "Unix" software runs on Linux with no problem. This
is especially so in the last year or so as software vendors have put
out Linux versions (often just repackaged with a new label). As for
Xess: http://freshmeat.net/projects/xess/?highlight=xess
>-Is most Linux software free?
Yes, but that's not the question you really mean to ask, after all if
Linux had no software it would all be free. What you mean to ask is
"is there a free equivalent of (or actual version of) everything
a normal Joe needs". The answer to this is "yes" as well.

Absolutely, I've used it myself. There's even a graphical editor call

Ask yourself two questions:

if I will end up better for it?

Yup. Call the second interface eth0:0. I did that for awhile until I got
around to buying another $12 ethernet card and turning my machine into a
real firewall. There is an IP-Alias mini-HOWTO, but it predates the GUI
network configuration.

I had the same trouble on a linux-only
fresh install and I had made the error of
selecting "first sector of boot partition"
for the bootloader during the install.
I could only boot from
a floppy under those conditions.
I did the install over again and chose
the MBR instead at that question, and
thereafter could boot properly from the
hard drive.
I am sure reinstalling is the long way around,
but it worked for me and now I won't make
that mistake again.

I have installed Caldera's Open Linux with the KDE interface - I know
that Linux purists are cringing, but newbies have to start somewhere.
Anyway my question is when I am moving through directories how can I
distinguish between file types? I mean how do you know a file is an
executable in Linux? If I want to put an alias on my KDE desktop (once
I find an executable file) how would I go about doing that?
Thanks in advance for your help.

The system-wide maximum message size is set in sendmail.cf (which
is created from a template .mc file).
Try /etc/sendmail.cf or maybe /etc/mail/sendmail.cf
Look for "O MaxMessageSize="
The number after this is the message size in bytes. This may be
commented out with a '#' to make the size unlimited.
You need to stop & restart sendmail after you modify this setting.
Use '/etc/rc.d/init.d/sendmail restart' to do this.

Thanks; putting a usable partition table on it meant that I could
format it using "DOS FORMAT."
I would much _prefer_ to be able to do so using a Linux-based
utility, but unfortunately fdformat and its successor "superformat"
are only "specified" to work up to disks about 4MB in size, which
does not suffice.
But I'm happy to have it functioning more happily at any rate.

See mod_include in apache docs. SSI code is executed before the page is
servered, so you cannot tell by "view source" what part of the page was
generated by SSI or the code used for it. Assuming you enable SSI
properly, the page name usually needs to end with .shtml instead of .html.
The following example works for me as long as it is not under suexec:
<!--#exec cmd="/usr/bin/uptime" -->
Under suexec you would have to use #exec cgi= or #include virtual=
pointing to a simple CGI something like this:
#!/bin/sh
echo Content-type: text/html
echo
/usr/bin/uptime

I don't think so. Type c is FAT32 (LBA) usually for LBA partitions larger
than 1024 cyl (8+ GB). My 30 MB card is type 4, but 64 MB might use type
6. Probably best to remove the partition in Linux fdisk and create and
format a FAT partition in Windows. I bet you haven't seen disk geometry
like this for awhile:
Disk /dev/hde: 6 heads, 32 sectors, 306 cylinders
Units = cylinders of 192 * 512 bytes
Device Boot Start End Blocks Id System
/dev/hde1 * 1 305 29264 4 FAT16 <32M
Something interesting I saw at www.ibm.com was a 1" 1 GB hard drive with
CF interface that fits in a pccard adapter.

CompactFlash is a solid state ATA IDE hard disk, not a floppy (fd).
Maybe 'mkfs -t msdos /dev/hde1'. I don't think vfat comes into play until
long filenames are written to a drive.

I did sort of what you are thinking of, but with Win98:
/boot 16 MB LILO
/boot 16 MB LILO
FAT32 (any size) Win98se
f Extended(LBA) multi Linux versions, shared swap, extra FAT
MBR is untouched, no worries about Win stepping on it. Either /boot can
be made active boot partition with Linux or Win fdisk. To boot the other
Linux you simply point each LILO to the other /boot partition as other. So
even totally erasing or replacing a Linux version does not affect the
other or the ability to boot (as long as number of extended partitions is
unchanged).

At last, a question where my newbie opinion may have some value. I've been
'playing' with Linux for about 9 months. At home I am totally Linux (my last
Mandrake 7.1 update did not go well and I clobbered my Win'95 partition).
>From what I've noticed so far:
- there are programs available for almost everything you'd want to do. The
one thing I miss from Windows is my fax capability. I've got efax downloaded
and installed but haven't managed to configure it to actually do anything.
- the variety of command line utilities in a standard Linux install is
staggering. I'd forgotten how useful simple text files could be if you've got
all the utilities to manipulate them
- compilers, interpreters and scripting languages are "standard equipment" (I
like Python myself)
- the learning curve on a lot of the stuff is very steep and newsgroups are
vital. This one is wonderful for newbies.
- there is a great variety in the quality of the applications available but
the price is right on most of them. StarOffice is a pig on my system (40 MB
Pentium) but it handles all of my word-processing, spreadsheet and
presentation requirements, once it finally loads.
I now find myself at work missing simple things like grep and emacs
(really!!) on my Windows machine at work.
