Harddisks are so cheap nowadays - I do a frequent disk-to-disk backup
(The magic word is "cp -a ..."), and now and then a recursive diff. This
lowers the probability for a full loss of some or all data to once in a
few
hunderd years or so. Best of all: practically no extra effort for the
backup, such as inserting a backup-medium.
Now: the residual probability for data-loss is dominated by infrequent
events such as an axe driven into the computer, fire, malevolent
hard-ware
or an air-raid. Have another computer in another room, connect it with
NFS and do the "cp -a" trick now and then. Then, the probability for a
full data-loss by pure technical reasons goes down to once in a few
million years.
Other influnences (intentional sabotage, system-administrator's error,
etc)
will cause a much more frequent data-loss.

Do you mean normal shutdowns or power failures? If you mean normal
shutdowns, do you use the "shutdown" command? If you mean loss of
power, then with a UPS you could code some emergency shutdown
routines.

The problem was that in setting up vmware I did not give it any access to my
linux partition (thus presumably lilo was unable to read /etc/lilo.conf). I
changed this to give vmware read-only access, and now lilo works fine under
it.

Reply-To: [EMAIL PROTECTED]

I use Lyx, not Klyx, but I simply set the margins for left and top to
small amounts, such as 1/4 in for the return address which in my case is a
graphic. Then you can set the next paragraph as centered with a defined
amount of space above it (such as an inch). By issuing ctrl-[enter] for the
line feeds it single spaces the address and centers it. If it is offset too
much left or right for your envelope size, change the paper size. Then save
the whole thing and use it as a template.
I have a second file of centered addresses and simply paste from it to the
envelope template for my envelope, otherwize just type in the address.
Works like a charm! :)

Check the commercial X servers; I think X inside advertises support for
this card --- but for the price you have to pay, it makes more sense
getting a good graphics card. I had the same experience and decided on a
ATI Xpert@Play with 8Mb; it works fine and cost me less than the for-pay

You know, you're right. A piece of software that allows you to surf the
web, view image files in a large number of formats, play audio files,
use plug-ins, render HTML including all industry standard tags and the
majority of non-standard ones including those of its competitors and
interpret embedded Java scrips and run Java applets really isn't worth
anything. My god - what was I thinking? Prejudice alone is worthy. I'm
converted. Never again will I miss an opportunity to snipe and bad-mouth
Microsoft - in fact from now on I'll take to calling them M$, 'cos
that'll make Bill Gates sorry for all those tens of billions of dollars
he's amassed forcing crap, unreliable, unusable, worthless software that

Umm, Redhat already shipped a 5.9 cd with the 2.2 kernel on it... They will

Have got myself in quite a sticky situation. This quite a long story but
feel if anyone can help i will have to put in as much info as i can so
please bare with me.
I have got Win95b and WinNT 4 WS station installed om my PC. A few weeks ago
my PC started booting straight into 95 with out giving me the WinNT NTLoader
menu. It didn't bother me much at the time as i didn't have any use for NT.
However i have now created a network between 2 PC's and would like to be
able to WinNT again. I have always wanted Linux on my PC and from what i had
read up about it, i could get 95, NT and Linux to boot up from the Linux
menu. So i installed Redhat 5.2 and tried to get Lilo ( Linux command
promt ) to see my NT boot sector. Uhh,uhh - no way. When trying to boot into
NT from Lilo i got tis error message ( A kernal file is missing from the
disk. Insert a system diskette and restart the system ) So that didn't work
although i could get to 95 from Lilo. Hokay, not so bad, more or less the
same situation i was in before installing Linux. So i decided to use the NT
repair disk option and go through the repair, During the repair i get this
huge message explaining that setup has determined that one or more of your
hard disks has more than 1024 cylinders. ( Not to sure about my cylinders
side of things - however at the end of this message it states "This message
does not necessarily indicate and error condition. It is intended to alert
you to the fact that one or more of your hard disks may actually be larger
than the size for which it is currently configured.
Right, so i read up on this and find that a DOS utility called Bootpart can
repair my WinNT boot sector - nice one! Try to repair it - all seems okay,
cross my fingers and then reboot the PC hoping that NT menu will appear or i
will beable to get to it from Lilo.l What happens, I get an error message
NTDETECT Failed and the PC hangs. So now no 95 no NT but linux is ok.
However when using the 95 startup disk, i can see al my files no prob and
using NTFSDOS i can see all my NT files. I tried to boot 95 from DOS and
got this error message." Registry file was not found. Registry services may
be inoperative for this session. XMS cache problem. Registry service may be
inoperative. A device or resource required by VFAT is not present or is
unavailable. VFAT cannot continue loading. System halted".
Pretty screwed huh!!! I am going to try and replace NTDTECT.COM this weekend
and NTLDR. But it's looking pretty grim for any recovery. I appreciate
anyone reading this huge posting and if you have the slightest hint/tip or
any info - i will be most greatful.

My Pee 2 350 with 64 Meg of ram runs the virtual Windows 95 at a
tolerably fast speed, not much more slowly than if I was running Windows
itself. The only noticeable speed difference was with screen refreshes,
but I was not using the vmware x server.
It works quite well, give it a try. The only reason I stopped using it

Actually, it was a valid rule in the '80's, too, where systems like
SunOS had to have at least as much swap as RAM -- if you had 32M of RAM
and 10M of swap, it would only use 10M of RAM.
So on SunOS4 systems, you'd need at 1xRAM as swap, and because the whole
point of virtual memory is that you can swap, 1.5xRAM was a reasonable
number. (If you needed 2X, that was a sign that your machine was
swapping too much and you should up the RAM.)
On newer systems (like Linux and Solaris), virtual memory = RAM + swap,
so the computation is somewhat different, since you don't need to count
the size of the memory into the picture.
> Now, there aren't any rules any more, get the amount of RAM you can
> afford and add as much swap as you need.
And there's still the problem of 'too much' swap: just like the '10%'
free space that the file system tries to keep around for slop, the
swap size usually doesn't scale well: if you have a gig of RAM on a
machine, using a gig of swap would still mean your machine was
thrashing like hell.
For most people, 64M of swap is plenty. If you're manipulating large
data sets (and hopefully your software is written well enough to
localize much of the data, so that unused data will page out and stay
paged out until its needed), that number can be raised much higher to
good effect. The catch is that a lot of programs don't do the necessary
work to localize things, and end up thrashing as they page in and out.
All the swap space in the world won't fix that, but RAM will.

Just recently A level, which means low level UG in the US AFAIK,
standard matrix algebra proved to be invaluable in a quantum
cryptography problem (research I did at Los Alamos National
Lab). Understanding linear indepence and basic column operations was
absolutely required. I can reasonably assume any CS person will
understand the results. (I have also actually used Lapace transforms
for real research).
>You just have to look closely at course outlines.`
And if you go to Oxford, and many other places, you will learn about
calculii that never talk about differentiantion or intergration. This
is stuff like CSP, CCS, and deriving programs from
specifications. Related stuff will also appear like Hoare logic. Use
of all these techniques without understandiung maths will be hard.
Maybe people who want to do CS and avoid maths should try reading a
few CS papers, Knuth and textbooks (such as Garey and Johnson's
NP-completeness bible). Throw in a tad of advanced statistics for
analysis of experimental results when you can not do the maths.
As for OO, JAVA and sutff like that many people with genuine CS
degrees do not swallow that stuff wholesale. Learning a new
intperative, or for that matter functional, programming language is
not a major challenge. If this is not the case for you then you
probably did the wrong degree. JAVA and C++ are just imperative
languages, enough said.
Of course if you want to be a real programmer then CS may be the wrong
subject. The desirability of real programmers is soemthing I decline
to make commments about.
