They're engineered nearly as well as the Sun boxes. And they work pretty well.
But their lifetime is half that of the Sun's. You don't see too many 6 year old compaq's in Datacentres. You do see plenty of high-end sparcs from that era.
Hell, I just decommed one. AT based K6-2 on cheap-shit clone hardware. Been running 24x7 for 4 years.
Wouldn't bet on it.
The only box I own that I would bet on is my SGI Challenge S.
Of course, it's been up 24x7 since 1996, first for the original owner, and since June for me. It did lose a hard drive in the process, but th rest of it is original.
On the same hardware, FreeBSD will handle more load, but Linux will handle the lighter load faster.
And Itanium boxes aren't even in the running for the fastest servers, unless you are talking Altix 3000 Clusters. Itanium is a bloody dog performance-wise. Now for a trulay fast server, you are going to spec high-class Power5 or Sparc hardware.
The OS has something to do with it. But I'm comparing Apples to Apples here. Solaris x86 to Solaris Sparc, and the x86 boxes still have more trouble handling the load than an equivalent sparc.
I do suspect it's more of a platform issue than a CPU issue.
The real question is how close to the standard x86 PC these things are going to be. The x86 platform isn't terribly well designed for Servers, although it's much better than it used to be. Especially the craptacular firmware restrictions that we're stuck with for compatibilities sake.
Image an Open-Firmware based Opteron. Oh, just imagine the possibilities.
That $10,000 will still be running, with full hardware support 5 years from now.
You'll be lucky to be able to buy ram with a warantee for that Opteron. Which will probably ahve bit the dust from component failures anyways.
Now a $5,000 Opteron or G5 on the other hand...
Just remember your cheap-ass desktop components may stand up to 3-4 years of mild desktop use, but the same components will die much quicker in a server.
The advantages of the Sun Sparc systems is not price/performance but reliability and performance under load.
Sure Solaris is a dog on a lightly loaded system. But when your load average is sitting at 30, it's still performing near the same level. x86 boxes would fail under the load that Sparcs can hold up under.
And they're bloody reliable, and when they break, Sun's support contracts are excellent. Only HP and IBM compare on the support side, and only HP and IBM's RISC boxes compare on the reliability side (lord knows IBM's Netfinities don't.)
It's all about TCO in the end. You buy the sparcs less often, and they're cheaper to maintain.
What she means is 50% of stupid UI hacks that rely on undocumented API's get b0rked when the OS gets updated because Apple has changed the undocumented API's.
The API's are undocumented for the simple reason that they will change (And they often change between point releases, 10.2.6 broke a bunch of these hacks, as did 10.2.8).
If all you do is use the stupid hacks to amke stuff loook pretty, don't bitch when they break because they weren't following the published API's (Which are quite stable).
Considering that software from the System 7 era still runs fine on OS X (Provided it used Published API's only), she has no real beef.
No, IR tops out at 4Mbps, Bluetooth tops out at about 500Kbps. IRDA is significantly faster than Bluetooth, but it's a PITA to use, unlike Bluetooth.
IMHO Bluetooth is in the position USB was prior to the introduction of the iMac. It's out there, it could be cool, but there aren't many products using it, and the marketing sucks.
The patch isn't broken in the least. You just need to specify which.TLD's you will aloow non-delegation records for.
People forgot to specify these rather obscure ones (The only one on the list I ever visit is.tw)
I take it that you are unfamiliar with how a VPN Functions.
A VPN creates a virtual tunnel over TCP/IP (Usually UDP) that emulates a private link between two nodes on the public internet. This link is normally (but not necessarily) encrypted. It looks like a direct link, but in fact traverses the net like any other traffic, encapsulated in another packet.
AOL's software creates a VPN Tunnel between the User and AOL's servers in Virginia. Thus you are effectively on a private network.
When you connect to an AOL users IP, you go via the AOL Network and the VPN tunnel.
That is correct. The reason they still do this is because the AOL Network is still to a great extent a private network connected to the 'Net via proxies. The private net has all of their extra content on it, and you are well firewalled off from the public net (Unlike most ISP's).
The silly thing is that everything tunnels to Virginia, even if you dial in from Australia. So overseas users get screwed performance-wise.
And in case you're wondering, I happen to be an AOL Technical Specialist for MCI, I support some of AOL's dial gear up here in Canada. So I'm intimately familiar with how it works.
Nope, the FX's to be introduced in January will be the 939-pin non-SMP non-Registered CPU's. The Current FX is a rebranded Opteron with DDR-400 support turned on (Opterons only do DDR-333 for reliability reasons).
You are connecting via the AOL Network. YOu still get a viable IP on a network connected to the Net, but you do not have a direct connection, since you are connected via a tunnel to AOL's Network (AOL hasn't owned it's own Dial gear since it sold ANS to UUNET in the mid-90's)
Right now it's the Powerbook 190 that I'm using as a console for my SGI Challenge S. That will be the winnner until I get my mitts on a set of NeXTSTEP 3.3 install media for my Monostation.
Oldest Hardware I ow that works? That would be a tossup between the Rev A Macintosh II (Circa 1987), complete with dual Toby cards and a Nubus Ethernet card(Surf the web, in dual-monitor glory, on a 16MHz '020), and the Epson Equity II+ (286) that I haven't thrown out since it was my first PC. The Mac II, with it's 128MB RAM ceiling and multiple monitor capability wins the award for the coolest 80's hardware I own. 90's hardware is a tossup between the SGI box and te NeXT, although if the SGI was an Indy instead of a Challenge S, it would win that for sure.

Compaq Proliant's ain't commodity.

It's both.

Agreed 100%.

Who cares?

Maybe on the desktop. But in the Server Room, Solaris and Linux are playing at the same level as Windows, with heavy marketshare for all 3.
And OS X is rapidly moving in to the low-mid server space, with Apple's excellent XServe 1U boxes.
The advantages of the Sun Sparc systems is not price/performance but reliability and performance under load.

True.
The router wouldn't likely do DNS. IF it did, it would be done with whatever DNS Servers you set up.
If all it's doing is Browser Redirects, that highjack would work, as you say.
Wouldn't work. As the Belkin Router is hijacking it at the router, not the PC. It would hijack the highjack and still go to the Belkin site.
Now if someone found a hole in the belkin router. you could do something far nastier, especially if you could flash a modified firmware.
yeah, remember that Laptop IDE is 44pins, not 40 (Which is SCSI)
NO, it's SCSI. All Apple Powerbooks were SCSI until the Duo's.
My 170's got a 40MB SCSI Drive, as does my 140, the 165 has an 80MB SCSI.
My 190cs has a 500MB IDE Drive.
Yeah, I've got a stack of old PB's still.
Neither does C, but Linus manages somehow.
And PHP can check types, so if you're worried, program defensively.
Yeah, you can. We call it Generation Z Cola, and it's available from Loeb's supermarkets in Ontario. Taste's exactly like New Coke.

NO, IBM uses the Power4 CPU, which is a 2-4 core CPU riding on a different bus design than the single core PPC970.
IBM also uses the Power5, which will come to the lowend next year as the PPC980 (Same bus as the 970).
Nope, the FX's to be introduced in January will be the 939-pin non-SMP non-Registered CPU's. The Current FX is a rebranded Opteron with DDR-400 support turned on (Opterons only do DDR-333 for reliability reasons).

Apple.
By a couple of years. BSD's only been dying since 4.2
Because AOL software is actually a VPN Application that connects to AOL's internal network.
YOu aren't directly connected to the 'Net when on AOL.
