Yah, I know what you mean here. They've sort of ignored that from the
start, but in the past few years they seem to be trying to make it up
with DDE and ActiveX automation, etc. Both of these are still BAD
implementations of this methodology, though.

I just hope that the X users don't split groups due to the Pro- KDE and
the Pro-GNOME. I wonder if those two will ever come up with a compromise
that can make everyone happy.

Actually, in one tutorial, I saw a section on interfacing with FORTRAN.
They made a program in FORTRAN to solve a quadratic equation, and
designed the front end with TCL/TK. That's okay, though. After my
"Advanced Scientific Computing" class, I can stand not to see FORTRAN for
the next couple of years. I d/led TCL/TK, and that's pretty cool. It's
nice to have that sort of power in a scripting language.
I also looked around at the GTK+ toolkit. It looks reasonable, somewhat
lengthy, but reasonable. It looks like there's a few GTK+ GUI
programming environments (RADs) on the horizon. I looked at some of
those, but I'm not sure if any of the ones I looked have a official
release yet.

I use diald and ppp. diald has the capability to shutdown an idle
connection after a specified number of seconds. This works well
for me. I also don't have to dial, as diald takes of this for me
automagically when I try to access a URL or an ftp site. It also
dials on my computer when my son or wife access the net from their
computers. It's a good program...

Gene Siskel of Siskel and Ebert movie review fame died today. I read an article about
him and
here's an excerpt.
Siskel graduated from Yale University in 1967. He joined the Tribune in 1969. He and
Ebert began their partnership in 1975 with the public television program "Sneak
Previews." They left the program in 1982, when their show went into syndication.

The shutdown processes should "remount" the root partition in "read-only"
mode as part of the process, and then the halt shouldn't cause any problems.
Look for:
mount -o ro,remount /
or its equivalent for the proper partition, in the /etc/rc.d/init.d/halt
script (or equivalent)

Language is only useful if we agree on the definitions of words. "Free"
is too ambiguous unless you are saying "I don't have to pay anyone for
the use (but not modification) of program X". "Open Source(tm)" means
something specific -- it definitely does NOT mean free in the full sense
of the word. Of course, you can convey the same thing by saying program
X is GPL'd and sidestep ESR altogether.
Aaaanyway, this is degenerating to the point of counting angels on the
head of a pin. Reasonably intelligent people that have some common sense
and the ability to read have nothing to worry about. Life is complicated
enough as it is.

:Hello,
:
:I'm using a Cannon BJC-620 printer. Under linux there are no drivers
:that support my printer so i am unable to use the 720x720 dpi
:capability. Do i have any options so i can enable all the features of

You should be able to use the bjc600 driver in ghostscript for this. Under
Red Hat printtool (supposing you are using RH) just select the BJC 600
option. I use this with my 4400, and it works OK. Only thing is to get it
to print grayscale and colour, you have to use 1 or 8 BPP and the extra
options -sProcessColorModel=DeviceGray
We also have a tool for use with Canon bjc printers on our site at
http://www.affinity-systems.ab.ca/software/ to do the software processing
that is done from the windows printer tool. I'm not sure if it works with
the bjc600 series (does with the 4400) but feel free to test it and let us
know if it works.

The Microsoft telnet program is seriously wounded. Get a shareware
replacement if you must use telenet from Windows. Better yet, replace
Windows with Linux on the telnetting computer. The Linux telnet
program works just fine...

Feel free to flame me for this, I'm sure that a lot of people will be offended
at the comparison but this is how I think of it.
If windows 95/98 had a window manager it would be the software that did basic
things like minimise, maximise, scroll bars, resizing windows, etc.
Gnome or KDE would be the apps like the file manager, control panel, display
properties, volume control, notepad, things like that, even minesweeper and
solitaire. The stuff that you can be reasonably sure is on every winxx system.
Even though some people for example may nuke the windows 95 file manager in
favour of a better one. Most people have this common suite of stuff that makes
up the basics of a "windows system".
And now, MS is trying to make IE one of these basic desktop apps. This is the
only real difference between windows 95 & 98. Plus some miscellaneous patches
like USB support etc.
Gnome is giving us the basic, consistent, suite of apps that lets us do pretty
much anything you need to do within the GUI. It's a good idea.
Or, flame me if I'm wrong.

The BJC-7000 is purported to work well with the bjc600 Ghostscript
driver. I am uncertain of how well black-only printing works; if that
turns out to work well (perhaps with another bj driver?) could you let
me know so I can update my listing, or just update it yourself?

Sudo *is* available, and works quite nicely too.

I know the bjc600 driver works with the 4xxx series BJC. To get it to do
grayscale with the black cartridge though (gs 4.03) use
-sProcessColorModel=DeviceGray
I find the 1BPP mode works better then the 8BPP.
