But you made the point about OS, were you running the same OS on both machines? Also PPC processors are very different beasts from x86 chips. PPC is a much more modern design and is designed for multitasking OS's, unlike x86 chips.
Well your Opteron cpu's on their own are a lot faster than his athlon 2600. Aside from that, i'm glad to see intel and amd concentrating on multi core, this will result in better multithreaded apps being written.. Multiprocessing can incase your speed TODAY.. faster individual processors will take a lot of time to develop.. You could go to CRAY or SGI today and get a system with 4096 processors, and multithreaded apps running on those systems could quite easily oblitterate any single processor system. Basically, it offers an upgrade path now (add more cpus) rather than having to wait for new processors to become available, currentl single processor systems are well down in the single digit percentages of the performance levels that exist today.
Which is why the mozilla rendering engine (gecko) can be used outside of the mozilla interface itself.. There are a number of browsers that do this, such as galeon, epiphany and skipstone and all have a massively faster interface than mozilla itself.
Most importantly, non gilette razors are on the store shelves alongside the gilette ones, there's nothing to stop you buying another brand. You have the facts in front of you (costs, availability of blades etc) and you make a choice which one to buy.
The difference is, you dont have to buy a honda, and you dont have to go massively out of you way to find a dealer willing to sell you a non honda. If honda had a monopoly on cars and the average user saw no other cars available or thought that other cars wouldn't drive on existing roads, then it would be a fairer comparison to microsoft. As it stands, there is competition in the auto industry, competition is good, if honda made such a nonstandard vehicle it would do no end of harm to their market share so consequently they don't.. But i'm sure if honda had a dominant position like ms does, they would use similar tactics to make sure they kept that position.
Well that's because ms stop releasing security patches for old versions, and old versions aren't extensible nor do they support modern hardware, finally prior to win2k, windows was unuseably unstable with the exception of NT3 so there was little incentive to use an old version. In contrast, linux kernel 2.0.x is still maintained, and will run on some most hardware, and if it doesn't your free to port drivers to it yourself or hire someone else to do it, it's also very stable.
I believe the statistics only count downloads of version 1.0, on any platform and with any language, they reset the counter when they released 1.0 and i'm pretty sure they don't count nightly builds.. Also, this doesnt count downloads from unofficial mirror sites (such as gentoo, debian, etc or other distro mirrors or sites like sunfreeware.com)
Infact, the inbuilt MP systems for Itanium is shared bus, and doesn't even scale well upto 8 cpus, just like x86 doesn't.. All of the vendors producing large IA64 systems are using custom systems too.
HP did have experience, the DEC Alpha Wildfire systems scale closer to linearly than anything else i've seen, and can go upto 128 cpus.. Unfortunately, HP decided to drop the Alpha and most of the good engineers migrated away.
Actually, Digital tried to phase out the VAX in the early 90's when the Alpha chips came out to replace them, but Compaq sold the last VAX system in 2000, when the replacement Alpha system had already been around for 8 years. So it took 8 years for some companies to move from VAX to Alpha
All of these processors were massively ahead of x86 at one time, and could still be if they had the same development effort pumped into them.. A lot of the die space on an x86 chip is wasted to support legacy applications so a modern chip would have an immediately advantage here.. Tho saying that, x86 is still being beaten on floating point performance by Alpha and POWER5 - even tho Alpha hasn't really seen any development for years.
Yes, just when computers got fast enough to compile 2.0.x quickly, we got 2.2.x.. But that's always the case... Software gets bigger and slower while the hardware gets faster, so that the overall user experience remains the same.
Lots of banks still use VAX machines running VMS.. As for active directory, why? novell's directory service works better and has been around much longer. Besides, before active directory came out and novell's directory service was the only option, microsoft were telling us all we didn't need a directory service, what's changed?
Well, why would it need to? It could modify your path/shortcuts/menus so that you didn't load the normal ssh client and loaded it's replacement version instead. If the spyware is running under your user id, it can screw with anything your doing anyway.
Sparc was never really designed for raw performance, but if you consider the performance drop as you increase the load on a system, sparc holds up much better than most other architectures and this is what sparc is designed for. Sparc also scales very nicely to large numbers of processors and is well proven in this field. Also, Opteron is much newer than sparc, a lot of businesses won't trust something that hasn't been around a few years and is well proven.
Unfortunately, if microsoft released a rootkit detection tool they would leverage their os to gain market share for their rootkit detection tool until such time as their competitors stopped producing competing tools, then the microsoft rootkit detection tool would stagnate. Also, with a single dominant detection tool out there, it would make the lives of rootkit authors much easier since they'd only need to test their kit against one tool and make sure that tool couldn't detect it.
You shouldn't need any special priveleges to attach to a process that's also running as your user, atleast unix systems don't have this stupid limitation, i've done lots of development on non root unix systems.
Actually it's pretty crap for "free" when you consider that OpenBSD's packet filtering is also available for free. Aside from the fact that the XP firewall is NOT free, it requires you to purchase a copy of XP in order to use it, therefore it's a component of a non-free product.

More ram and a fast scsi controller or two would probably help you more than another cpu..

It makes quite a difference on a multiuser system linked to multiple dumb terminals...
Where did you get this information? does securityfocus have a stats page?

Only they dont actually produce the keyboards, they just rebrand them.. Their mice suck too, very easy to break compared to a logitech.

A Sparcstation-20, which can often be acquired for free nowadays, will outperform any opteron for the same price!
A real rootkit would try to make itself look like legitimate tools aswell, to reduce the chances of it being identified and removed.
The real superuser is actually called SYSTEM.
