Since XML wasn't around, I think it is rather the case that if HTML had paid more attention to SGML than "it's tags enclosed in <> signs" we might have had true separation of data and presentation from day 1, and DSSSL might have been something people would put on their resume.

You can't. From mke2fs -i bytes-per-inode Specify the bytes/inode ratio. mke2fs creates an inode for every bytes-per-inode bytes of space on the disk. The larger the bytes-per-inode ratio, the fewer inodes will be created. This value generally shouldn't be smaller than the block- size of the filesystem, since then too many inodes will be made. Be warned that is not possible to expand the number of inodes on a filesystem after it is created, so be careful deciding the correct value for this parameter.

It's very easy to plug an arbitrary non SNMP data source into MRTG. The output just needs to be in the format Line 1 current state of the first variable, normally 'incoming bytes count' Line 2 current state of the second variable, normally 'outgoing bytes count' Line 3 string (in any human readable format), telling the uptime of the target. Line 4 string, telling the name of the target. As an example, openupsmart (openupsmart.sf.net) when running will give status output on a port like this : [EMAIL PROTECTED]:~$ /usr/pkg/sbin/nc localhost 8740 248.0 58.0 28 days, 21 hours, 46 minutes, 35 seconds OpenUPSmart This can be snarfed into MRTG with a target like Target[ups]: `/usr/pkg/sbin/nc localhost 8740` MaxBytes[ups]: 300 Title[ups]: UPS Statistics PageTop[ups]: UPS Statistics YLegend[ups]: Power Statistics ShortLegend[ups] : LegendI[ups]: Volts LegendO[ups]: Load options[ups]: gauge, nopercent You could use openupsmart if you wanted; there is a UPS "simulator" included in the source which you could quite easily modify to return some sort of reasonable random variables to make it look real.

LP64 where longs and pointers are 64 bits (Linux, most UNIX?) and the Windows model where only pointers are 64 bits. Many might suggest this is because so much Windows code would break if long suddenly became 64 bits, but I think the official reason is efficiency within the API. In both cases an int is 32 bits. In both models a long long will be 64 bits, no matter what your architecture.

When thinking about why things are as they are, it's always good to consider the alternative outcome. Imagine if the size of int did increase to 64 bits. Firstly a lot of code would break. That's a bug, and would eventually be fixed after some initial pain. Suddenly every int variable now takes up twice as much space, every array of ints is twice as big. This means binary sizes increase and, more importantly, you waste a lot of your cache. How often does a loop counter overflow a 32 bit variable? To be sane people would have to reduce the size of variables they know won't overflow. So maybe you could make a short a 32 bit variable on your 64 bit machine. But now when people try to move their code between machines might find their counter becomes 16 bits, which is much more realistically overflowed. Now programmers have to be concerned about sizeof(int) and sizeof(short) to maintain portability. It would be a debacle. 64 bits is mostly about addressing; the times we need to cater for 64 bit variables that aren't addresses are limited. I'd still consider an AMD64; there are a number of architectural enhancements over x86. Of course if you want a real 64 bit architecture, pick up an Itanium from somewhere :) -i signature.asc Description: Digital signature -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

Totally unrelated to Linux, but ...
I've never noticed these channels before. Does that AC3 refer to
Dobly Digital, and does this mean those channels are actually
broadcasting with full 5-channel surround sound?
My set top box shows me an alternative digital audio stream for most
channels, but when I put it through my speakers it's only ever the

the true "surround sound" signals.

I'm not sure about why the minipages overlap, but I had to do

Looking back at your original example, Latex is assuming you are using
a portrait page, which isn't wide enough to get all that stuff in.
Thus Latex then just shoves the boxes ontop of each other.
I think what you need to do is make sure you have something like
\usepackage[a4paper,landscape,noheadfoot,margin={0.25in,0.25in}]{geometry}
to setup landscape mode (and thus set \textwidth properly to something
nice and wide). Make sure you don't include anything like
\usepackage{a4} after it, because that will reset \textwidth.
You can check the width with the \showthe command (\showthe\textwidth)
to make sure it does look wide.
