...and said systems can't spread threads across multiple CPUs, so you just lost one of the main benefits. You need context-switched threads to do SMP and Linux' context switches are faster than most of the systems that use userland threads anyways.
Yah, if you have multiple processes contending for time at once, SMP will help as well, but my point was that most people only have a single task running at once, and in any case two pentiums running at half the speed of a PII aren't going to outrun the PII.
Even if you're doing parallelizable tasks (compiles etc), given that a PII 450 is going to be at least twice as fast as two pentiums, irregardless of speed, you won't gain anything besides the whole "damn SMP is cool" thing. In terms of SMP in general, "it depends." If all you do is play games, or browse the web etc you won't get any benefit out of SMP. If you do things such that there can be multiple tasks all vying for CPU at once (parallel compiles, scientific multithreaded/processes computations etc) then SMP can be a win. For most people, it probably isn't.
I pick these up whenever I find em. However, I know that many of the earlier PS/2's did have the good-quality keyboards. (I've stolen some from them myself:> )
It's well known that OS X runs on top of NeXT, a Mach OS, and Mach is most like a "BSD 4.4" variant, not a "FreeBSD" variant. FreeBSD in fact most likely postdates Mach by several years.
Jobs is in charge now, and he wants to use his Baby. And whatever the Apple fans say, Apple *doesn't* like free source. The BSD license has the advantage for Apple that they don't have to give anything away.
Read the license, the Sleepycat license is *not* a BSD license although it looks like one at first glance. The principal issue is that they require source code redistribtuion, soemthing which is anethema to the typical BSD license.
There used to be a neat cd-rom server package called 'cdfile' available from http://www.psocd.com (or www.pso.fr) which would cache files etc so that you could use the cheap cd changers (I have a Nakamichi 7 disc) unfortunately it was priced at like $50/disc so it was out of my price range for personal use, and the domain doesn't seem to exist any more.
If you want lots and lots of cds you might need to use devfs if you run out of devices. Hardware to look at if you're rolling your own would be the Mylex BT-930 which is a cheap dual channel ultra narrow controller, or maybe the Diamond Dual Fireport 40 if you can find them. You can also find preassembled cd towers which translate the scsi ids to LUNs so you get more mileage out of your scsi cards. www.corpsys.com usually sells this sort of stuff, although you pay for it.
Just remember, Redhat has GPLed *everything* of theirs, including the install program. This may have changed, but at one point the same couldn't be said about Slackware & SuSE.
If you like it, cool, use it. If not, use something else.
Some people (including me) really hate Track Pads and would prefer a trackpoint. (aka eraserhead) Unfortunately, IBM and Toshiba (and some Winbooks) are the only laptops you can get them on these days...

It happens both ways, you see Europeans bash Americans on/. and vice versa as well. And it does happen in real life too (I've had a couple of Europeans discuss in front of me how uncultured and stupid Americans are). Just accept that there are idiots out there and do your best to ignore them. OTOH, I think sengan's post was inappropriate. If he wants, he can post an immediate followup with his pontificating, but I (and others) would appreciate it being kept off the front page.
While I don't necessarily agree with the sentiment of the above article, I do agree that Sengan shouldn't be using this stuff to give a billboard for his own views.
Come on now, what did your mother tell you? Just because one person does something doesn't mean it's ok for others to as well. IMO at least, it's worse when someone who has some reputation as an authority engages in a FUD campaign than when some random guy posts a flame on/.

I really like the WM setup those screenshots there have. Anyone know what WM it is/where one can pick up the config files?

The Frame buffer console was ported over to x86 because the PC98 spec no longer requires a text mode on video cards - so, in the future, it might be impossible to use Linux on x86 w/o a frame buffer console. As others have said, in the mean time, if you don't like it, don't use it.

You're right, I was thinking "irrespective" but a neuron must have misfired.

I believe Redhat has said that 6.0 will definitely have glibc 2.1, gnome 1.0 and a 2.2 kernel in it

Agreed, much better than several of the phone-based ISPs I've had.
PIII is just a PII with some cache changes etc. If you mean the new "Katmai" instructions, that's a user space issue, not a kernel issue.

Kick ass, thanks. I compile my own fvwm2 anyhow. :>

It's worth pointing out the GALE project as well.
