I wish to add the following clarification to what I meant by
"preserve a copy" above.
It should be a simple matter to modify the logic of the "secure
delete" option prexisting in the ext2 filesys, as follows:
pseudo logic:
if (file has one link only and is of attribute "secure delete") {
overwrite file with zeros
/*
modify as follows:
if directory ~/.shredder exists then make a new link
*/
unlink original file
}
Of course a disk-to-disk "copy" would be worse than useless.

I have just set up the VESA VGA graphics Console. It works fine
except at a resolution of 1280x1024. At this resolution, my monitor
shuts down every few minutes for about two seconds. It then recovers
and everything is fine for a while. This also happen under X.
Has anyone else seen this problem?
I am currently running Kernel 2.1.1 although the problem also occured
when using kernel 2.1.122.
My motherboard is an Asus TX97-E with a Cyrix 6x86Mx 233MHz processor
My graphics card is a Raven 3D (Voodoo Banshee).

Subject: Using message queues from kernel land, and other stuff...
Date: Wed, 03 Feb 1999 00:00:17 -0500
I am currently working on a module which utilizes kernel space fs
operations and user space management operations. I would like to do
something like using IPC message queues between the kernel and user
operations. Unfortunately, it appears I can only call msgget
(sys_msgget), etc. from a user space context. Can I get around this?
In depth info & example code heavily appreciated. Also, for the same
project I was considering using procfs instead for the passing, is there
a good example of doing this within an application. Basically, what is
the most standard way to implement kernal-call-different user type of
operations?
I know there are a lot of different ones, and the largest part of my
troubles have been utilizing methods no longer current with the changing
linux kernel (developing for linux 2.2.0).
Thanks in advance for the help,
Todd Stockert

The books you have mentioned are very good, especially the Steven's
(his network programming volumes are excellent aswell). The Bach
book is good too, although a little outdated (it describes System V
how it was in the 80'ies).
Other excellent books (listed off the top of my head) are
McKusick et. al., "The Design and Implementation of the 4.4BSD
operating system" (also worth reading if you're not interested
in the BSD system in particular since the architecture description
holds true for most Unix systems), Uresh Vahalia, "Unix Internals -
The New Frontiers", which discusses system level similarities and
differences between the various flavours of Unix used today and most
books of the O'Reilly series (most bookshops with computer literature
have them) which are good introductory books to various aspects of
using, administrating and programming Unix.

Unfortunatly, some cards look a lot alike to a probing driver.
I would parse /proc/pci first, followed by parsing the output from
pnpdump. For legacy ISA cards, I have no idea.

What is the difference between the two? We run the FEA app EMRC/NISA Display 3
v8.0 with Exceed 6.01 which is a Unix app. Just curious about the differences
between the term "environment" and "emulator". We also have programmers doing
some development using Exceed.

Hm.. Perhaps, after examining Microsoft's financial status, and the U.S.
gov't's, I might just favor MS becoming the state. I can't picture MS giving
billions of dollars to various peoples whose primary goal is the destruction
of MS... at least not willingly.
But it's not an either/or proposition. You will have a certain amount of
socialism, you will have a certain amount of capitalism; that's the nature
of the beast. If socialism were purely contra-survival, pack and tribal
animals would have ceased to exist long ago. If capitalism were
contra-survival, all life would have become extinct even longer ago.
My personal favorite variation goes something like "from each what he is
willing to give in his best interest, and to each the fruits of his own
labor"

There's no reason why it should. I'm currently (off and on) working
on a GUI component that will run on both Win32 and Linux with
identical application source code. If it's possible for GUI
components to bridge that gap, I'm sure it would be easy enough to
make the jump to the belowmentioned forks.

I guess these guys had reasons for their forks. I don't see why a
single GUI layer couldn't ride on top of all of them who wanted to use

Although X-Windows is specific to Unix, Exceed is just a port of the
Unix X-WIndows server to the NT Os and runs natively (in other
words was compiled with Msoft tools and API's) vs. interix which would
run a shell within NT so that Unix apps could run within it. Of course
the Unix apps would have to be recompiled if they are static vs. dynamic
with respect to the libraries. The reason is, is that their stuff can
be considered a dynamic library that maps Unix OS API calls to NT OS
API calls, thus making the OS transparent to the Unix app.
So I guess in summary their stuff acts like a Uni emulator within Windows
by either or both providing a dynamic library/API mapping s/w package
and a shell that traps or allows Unix to run within its own environment.
