Date: Mon, 16 Aug 1999 20:31:03 GMT
Hello,
My BJC-1000 printer doesn't produce any output. In printtool, I tried
BJ-200 filter and text only filter. Without success.
So, is a ghostscript filter available for the Canon BJC-1000 printer ?
If not, is it possible to use this printer with another filter.
Thanks for your help.

Just a bit of free advice..jumping from Basic to C is painful :)
You might want to try learning Java first and then go to C/C++ from there.
Free development kit downloads are at: http://www.blackdown.org
and plenty of good books on the subject are at: http://www.oreilly.com
Learn all the languages you can, really, but Java's good for teaching
"object oriented programming" (the latest industry buzzword ;) and gives
nice instant gratification with its built-in graphics libraries :)
But back on topic...I'm a programming nut. I started with Basic on the
Apple][ and made a habit of looking through other peoples' Basic programs
to find useful tidbits I could add to my own programs :) But, the things
I wrote never did get fast enough (despite plenty of optimizations on my
part) and I'd run out of memory - often.
Eventually I moved on to college and SunOS boxes (in the pre-Solaris days
:) running X and programming Pascal with vi and friends. That was quite a
jump! I had no idea about DOS/Windows (having never used them) and
encountering Macs was seldom. But I got to know general day-to-day UNIX
very well and thought Pascal was a lot of fun - a lot better than Basic,
at any rate! All of a sudden I could *compile* programs and have actual
executables! I was amazed :)
Then, of course, I moved on to C. That was a bit on the painful side. C
isn't very forgiving of mistakes, and it wasn't taught to me very well. A
simple explanation that "all C functions are pass-by-value" would've
helped me quite a bit through the whole pointer/address fiasco. C++ went
quite a bit better, but I haven't had a use for either in quite some time.
That's just the nature of my current employment, really.
Just for fun, I moved on to Java and got very good at it. So good, in
fact, I wound up doing a few too many system-level programs in Java simply
because I didn't know anything else well enough to do things fast enough
(I found C/C++ quite a bit too low-level, for example). I still dabble in
Java where it's best suited, but I leave the day-to-day stuff to languages
better suited to the task ;)
I moved on to Perl from there and found it a whole lot easier to get a
whole lot more done than I did with C, or even Java for that matter since
basic things like resizable arrays and hashtables were built right into
the language - instead of instantiating yet another Vector :)
I started hearing about Python and tried learning it from online
tutorials, but the docs I found made better references than learning
materials. When O'Reilly's Learning Python was finally published, I
snatched it up right away and was hooked. Finally, all the powerful
language features I liked in Perl with the "practically everything is an
object" philosophy I enjoyed in Java.
At the risk of starting Yet Another Boring Language War, I'll give my
personal experiences on the subject a rest and move on to more Linux-type
matters :)
Eventually I did find my way to DOS and Windows3.11, and it wasn't a
pleasant transition. I missed having a powerful shell. I missed xterms.
I even missed xv and pine. Every single Windows(3.11) program I used felt
cheap compared to their big robust UNIX counterparts. Doom was the only
thing that convinced me DOS was pretty valuable to have.
Maybe my experience has given me a "tainted" outlook of the typical Wintel
world, but I honestly missed having compilers included in an OS along with
a myriad of "sharp pointy tools" to get day-to-day jobs done. Strange as
it may seem, for me it's much more satisfying to see a list of my
PalmPilot apps using "pilot-xfer" than with any window-driven utility. Or
to get a listing of mp3s using "rio" and having them show up in an xterm,
for example. I don't claim to be a typical user, but there's something
about interfacing with fancy new hardware using raw text that just feels
more "real" to me.
That's why when I finally decided to pick up some hardware for myself,
Linux seemed the obvious choice. Not because it's "trendy" or has pretty
desktop environments, but because I can use bare-bones window managers to
fill my screen with xterms and emacs'en. That's the environment I feel at
home in, and it's where I get the most work done.
Enough of my ramblings for now. But after 25 years, I've found a
programming and working environment that I like. And I won't budge until
something better comes along :)

Subject: ksymoops ??
Date: Mon, 16 Aug 1999 23:33:57 GMT
In the IR-HOWTO there is a reference to a program called ksymoops:
"If anybody gets a kernel Oops, then please feed it to the
../linux/scripts/ksymoops/ksymoops program, so that we can find out where it
went wrong. Just cut out the Oops lines from the syslog, save them to a
file, and then run ksymoops <file>"
I've looked around on my RH6 system and don't have this program. There's
also no standalone program by this name in the RPMS dir on my CD-ROM. Can
anyone enlighten me on this? Is it part of kernel development tools?
(Something I didn't install).
Also cannot find other references to kernel Oops. Again, is this a kernel
developer's symbolic dump or something like that?
I'd love to read up on this if anyone can point me to some relevant docs.
I've searched through all the HOWTO's and have come up empty.
TIA,
Gene

Subject: crontab questions
Date: Mon, 16 Aug 1999 23:34:24 GMT
As far as I learned I am able to create my own crontab file
by typing crontab -e (... and to insert some lines..)
Well, if the sysadmin (I am only a user) had to shutdown the system and
to reboot. Does the system know that there is a "private"
crontab file anywhere in the directory structure ?
Does the system start all the private crontab files or do I have to do
that by myself because only the "general" crontab file is referred ?
Is there a startup file where I can/must insert a line to start my
private crontab instruction (which ?) for reboot purposes ?
As far as I know the sixth parameter of each crontab file
represents only and only in "general" crontab files.
In the "private" crontab file there is no user parameter in crontab
files. Is this correct ?

I've frequently wondered why other OSs don't become more popular. I'm use linux
almost exclusivly at home (I also have BeOS installed, which I do use, and Windows,
which is only used to play games, but I usually don't since the effort of rebooting
just to game is too much), and I've frequently wished for more modern OSs. I know
they are out there, but when ever I read about one, I usually also find that it is too
early in development. For profit I do database programming, and for fun, I write
heavy duty media programs (or at least attempt to). What I do for fun is really
pushing
the edges of linux, let alone stuff like Plan9 or GNU/Hurd, and since I don't have the
skill or desire to do systems programming, I'm stuck using more established stuff.
I was quite excited when finally a version of BeOS came that would run on my hardware,
but I was quickly quite disappointed by the network services. It probably is a picky
point to complain about their primitive web browser, but I found myself needing to
reboot to linux anytime I needed to get something from the web, which isn't good if you
hate rebooting like I do. Also, I had trouble with networked file access (i'm told
that is fixed in the latest version which I haven't yet installed), which made getting
files to work from the server a real pain. Finally, I was disappointed by the fact
that it wasn't really a multiuser system.
On linux, for some tasks, I wish I had a pervasively object oriented system like BeOS
or NeXTStep, or many other less developed systems, but for various reasons, I was never
able to use them, or was unsatisfied. Don't get me wrong, I love linux, but I am
frequently left wondering if it couldn't be much more powerfull is wasn't lugging
all of the unix legacy behind. Stuff like BeOSs file system look really cool, not to
mention the NeXTStep display system (if only it could operate remotely like X11 does),
or the way ActiveX and OLE provides services (I think the implementations is awefull,
but I've never seen stuff like corba do the things that I do with ActiveX). Hopefully
someday soon peope will take something like Hurd, or Linux, or other free OS and turn
it into a more modern OS that is just as flexible as Linux, Irix, or Solaris is (I
don't consider *BSD, Windows NT, NeXTStep/OpenStep/MacOSX, or BeOS to be as flexible.
Each of those either lacks in the workstation arena or the server arena).

Well don't know about the first problem, never booted linux just from a floppy,
but you're 2nd problem imight be able to help with.
first, do this
$ echo $PATH
You're looking for /usr/bin in the path. If its not there problem solved!
Type this command
$ export PATH=/usr/bin:$PATH (if bash is your shell)
$ setenv PATH /usr/bin:$PATH (if csh is your shell)
Try make again. If it works, you may want to edit /etc/profile and add
/usr/bin to your search path. If not, you'll have to install gcc. I'm not
sure what package that is in.

I just got VMWare myself. It is really nice. A bit slow on my AMD K6-3 400,
but usable. I've run into a couple of "gotchas", but I think that I
understand. The first is that when I invoke VMWare, any error messages
are always directed to my tty1 (not the xterm that started VMWare). Since
this VT is normally my "root" login, this looks weird. I just use a different
VT now. Second, since I want to read floppies, VMWare "takes over" the A:
drive. I can't mount it to Linux while VMWare is running. The same is
true of the /dev/modem. So, VMWare does not share these resources
dynamically. Since I rarely use the floppy in Linux, this doesn't really
matter to me. The modem is a bit of a problem, however. I use Linux
for my Internet access. I would like to use Windows98 for my dial in to
work since the terminal program that I use (BlueZone) is a lot easier
to use than minicom.
I've only been using this product for about a week. Oh, you do have your
Windows98 CD handy, don't you? If you use the "virtual disk" capability,
you must do a full Windows installation from the CD. From what I've
read, you can use the "raw disk" functions to directly read your current
Windows drives, but it is STRONGLY discouraged. And apparently very slow.
I'm now trying to figure out Samba so that I can use Samba to access
the Windows drives which are "mounted" to Linux. Also there is a news
server for VMWare (news.vmware.com) which anybody can access. There is
a lot of good information available in the forums on that news server.

I've been able to do that with a non-root userid. The command looks like
the one you entered. However, the sysadmin can stop this by using either
the /etc/cron.deny and/or /etc/cron.allow files. Those control who may
and may not use cron. You *might* be able to "cat" those files. Or maybe
not.
The difference between "cron" and "at" is that "at" sets up a one-shot.
You say something like:
at 1700 tomorrow
And type in the commands. They will run at 5pm tomorrow. And that's it.
cron is used for repeative functions. I use it as a type of alarm clock.
It tells me to get up, go to church, take my medicines, when my fav TV
programs are on. A real nag! <grin>

As I understand things, UNIX isn't really an operating system any
more. Rather, it's a brand, owned by The Open Group, that gets
confered on operating systems that successfully jump through certain
hoops. It's my understanding that Linux has not yet jumped those
hoops, but could easily be made to via a few additions such as a
streams package. I also understand that Microsoft has contracted out
the project of getting Windows NT through those hoops. ;-)
