Hmm, for about a half a year I've been using spellword and fixwords to
spell check a word at the command line. spellword with output correct
or incorrect, and fixwords will give you spelling matches that you could
choose.
<P>
I use Debian Linux, I don't know if it comes with any other
distribution.

I ran the "Spell checking a single word" 2c tip from the March issue as a
bash alias and it deleted all the files in my home directory. The below
shell script will work a little better for bash users. Also, even for tcsh
or any other shell, I don't recommend the "rm -f ${j}*" construct. If j is
not defined it results in "rm -f *" which is what happend to me.
<PRE>
#!/bin/bash
j=`mktemp /tmp/mspell.XXXXXX`
echo $1 > ${j}
ispell ${j}
cat ${j}
rm -f /tmp/mspell.*
exit 0

Well, you could try using the StarOffice to open that file, maybe it
will work.
I have try a few times, and it works star office can read the
"corrupted" MS Excel or MS Word files thought some format like borders
might be gone. But most data are still there.
<P>
Maybe you guys or gals out there would like to try out.
If it works for me, it might work for you too....

I use this script to backup or clone directories. I happen to call it
mirror.
<pre>
#!/bin/sh
echo "Which directory do you wish to copy, oh great master?"
read SOURCE
echo "Which directory do you wish to copy the contents of $SOURCE to?"
read TARGET
cd $SOURCE
tar cfp - . | (cd $TARGET; tar xvfp -)
exit
</pre>
Now my shell scripting abilities are rudimentary at best. I invite all
flames, comments and suggestions to the above email address. I'd like to
know how to get some sanity checking, (do the directories in question
exist, and if the target directory doesn't, maybe offer to create it).

You may want to give 'xvidtune' a try. It's an X-based program (usually
included with standard distributions) which allows you to 'tune' your
display to fit your monitor, then display the clock settings which work.
<P>
You've got to be root to run the program.
<P>
When in the program, use the left/right/wider/narrower and
up/down/taller/shorter buttons in conjunction with the 'Auto' button.
Clicking 'Auto' first will allow you to view the changes real-time.
When you have a good image, click on the 'Show' button. This will
display the current clock settings in the x-term from which you launched
xvidtune. You'll also see the hsync/vsync ranges in stdout as well.
<P>
Put this line in /etc/X11/XF86Config in the "Monitor Section". You
should see other examples beginning with 'Modeline'. Myself, I actually
have this as the only line in the Monitor Section, as it's the only one
I need. This is probably wrong, but like I said, it works for me.
<P>
This all assumes you're running XFree86, as that's all I have ever
worked with.
Hope this helps,
<P>

One of the areas where open source software still has a long way to

I have not yet seen any "Linux Software" which can really be compared to

If you get WINE you can run them under X,

I think what you see here is the result of Win98 stumbling over a filename
with multiple periods in it. I get a similar result on Win95, as well as on
Win-NT4.0, only the name in my case is mangled into xxx_tar.tar.
So when you have the dialog for the download on screen, you can simply
change the name into something like xx.tgz, which is unpacked by e.g.
WinZip with the same ease as if it were a real ZIP file.
Note for LG: maybe this would be an alternative for the names you use on
the website?

Well, I was trying to install/upgrade from quazimodo RH4.2/5.0/5.1
system w/ 2.0.36 kernel, and brilliant me decided to try and add some
partitions. Throw in some DOS as well as Linux FDISK mayhem,
downloading Norton Utilities 4.0 (for $50...), about the only right
thing I did when having NU try and "repair" one of my partition tables
(the one with the one ext2fs partition I really wanted to keep), I did
make a backup before NU mangled it, leaving only the DOS partitions.
<P>
I also have Partition Magic 3.0, and the errors for my drives I was
getting were #120 and something else that changed into #120, where the
description was something like:
<P>
DOS requires partition table to be in logical order. Other FDisk
tools (like Linux's), create partitions in the order they're created.
<P>
So I couldn't use PM to back myself out of this hole.
<P>
I downloaded a free program (I think!) called Partition Master, put it
on a DOS boot floppy. I found it searching around on
http://www.hotbot.com/
<P>
Rebooted from floppy, ran the program. Hmm... it shows you the raw guts
of the partition table. So I deleted the partitions it had flagged as
bad for one reason or another, after restoring my failed partition fix
on the 2nd drive, and fixed that drive's partition table with this
program as well.
<P>
Reboot, windows. Partition Magic could see my partitions! Yay! OK,
delete ALL the partitions I didn't really want so I could redo the LInux
partitions correctly (i.e., start with /, then /usr, then /usr/*'s,
etc.).
<P>
OF course, that little program was really what I needed in the first
place (why didn't Partition Magic 3.0 have such a tool? Oh well)...

Well, my IBM Aptiva came with a Lucent Technologies (LT) WinModem.
<P>
From one of the IBM support pages, apparantly somewhere in Windows
exists a DOS tsr to make the WinModem work from DOS.
<P>
...but I haven't used it.
<P>
In theory, it would represent (at least) two WinModem options for those
other people with LT WinModems, and possibly other WinModems as well:
<P>
1. Run this TSR under DOSEMU.
<P>
2. Someone with the expertise to suck out the relavent x86 code from it
and incorporate it into a device driver. That person, however, isn't me
unless I win the Lottery, thus freeing up lots of time.
<P>
The Lucent Technologies site has basically 0 info on their WinModems,
since they only OEM'd them, and thus refer you to your PC's manufacturer
for any info.
<P>
Wish I knew of sites to get info on WinModem technology. If HP is slowly
releasing info on their printer control protocol (I don't mean PCL...)
for their WinPrinters, maybe... but probably not.
<P>
For a real scare, check out Nick Petreley's hoax article at
http://www.infoworld.com/forums about Microsoft-Intel WinPC, where
*EVERYTHING* on the board runs this way. It was a hoax article, but it
is totally concievable.
<P>
Send me e-mail if you want me to accidentally attach the TSR to a mail
message.

No, as far as I know, LINUX currently does not like WINS.
<P>
It should not be too hard to change though, it would involve modifying the
DNS daemon code to query the SAMBA nmbd process in addition to any other
DNS servers.
<P>
Microsoft does this by adding a new record type of WINS to the DNS that
contains a pointer to the WINS database. Someone modifying the DNS daemon
code could probably adopt the same record format.
<P>
There is a faster way for you to get things working if you have a NT SERVER
Version 4.0.
[IIRC NT Server 3.51 does not have DNS] The built in DNS that you can set
up on Windows NT Server 4.0 will can be configured to query the WINS server
in that fashion.
<P>
You can configure that DNS as a caching only server, and it will make all
the Windows systems visable on the DNS with manual tweaking.
<P>
The NMBDQUERY tool from the SAMBA product could do what you need to do. It
queries a WINS database. Assuming the person is only logged in at one
windows system, their name should be mapped in the WINS database with the
IP address of that system.
<P>
That is also assuming that your windows boxes are registering with a WINS
server or the SAMBA nmbd equivalent.
<P>
While it accesses the common conf file, it should not require the SAMBA
daemons to be running.
<P>
see www.samba.org if the information is not on your LINUX distribution.

You shouldnt have any issues with any of the hardware listed. The DSL modem and
the POTS splitter wont be installed into your PC. Those are external devices to
allow you to use DSL. The only other devices then left is the NIC. That
Kingston Card should work fine under Linux . Ive used other Kingston cards in
the past but not that particular model. Of course if you already have a NIC in
your Linux box then all you will have to do is plug a network cable from the
DSL Modem into your existing card. A bit of advise about when the installer
comes out...boot into 95 and let him verify that everything works. The guys who
do the installs arent usually the brightest people (from my experience) and the
have only been trained to deal with Wintel and Macs.
