"...Not to muddy the waters, but even if the root account is disabled, you can 'sudo su' which the prompt then tells you that you are indeed root..."
Isn't it the uid that truly determines root (and isn't that what the exploit does - hijack the root uid)? If it's the uid that determines root, then is this what "sudo su" invokes? I mean, after "sudo su" are any commands I then issue from uid = 0?
Ok, I just answered this myself. Relatively new install of Jaguar on a Wallstreet PB, root account never been enabled, opened a terminal, first "sudo su", then "id". I'm root alright.
In 10.1.x, I believe that you can highlight the service, and click on 'Configure' to disable 'Use DHCP-supplied LDAP server'. Not sure, though, since I just (2 days ago) finally got my old PB to run the Jaguar installer.
"...Then, as you have read it, you can tell the world how you do this "low-overhead software error correction to compensate for the non-ECC memory"..."
Taken directly from interview with Srinidhi Varadarajan:
Q: How do you deal with Error Correction in Memory?
A: There's a lot of traffic on Ars Technica and other places. We do failure recovery, memory doesn't report. One of the things we've noticed is that failures aren't an issue yet. The reason they can be competent is the LINPACK test, which is showing 16 digits of accuracy. We are planning on moving to ECC systems in the future. They may have to run things twice for a bit.
"...but you can usually hold the player's eject button while it's powering on..."
If you hold down the mouse button (left-click) while a Mac it booting, it ejects bad disks. At least, it's always worked for me, even with unseen, unmountable ones.
"... I'm in graduate school now, and since I'm taking an accounting course, where they don't want us digging out our laptops during a test, I need to buy another calculator..."
So what calculator is this that has a "Start" button? Perhaps you're talking about a PDA. Does it do Reverse Polish Notation as well?
Very good points indeed. However, even then, lets say that Apple has a 20% (optimistic) and PCs have an 80% installed base of overall desktops..8 *.2 =.16 or 16% overall and are PCs.2 *.8 =.16 (funny how that works) or 16% overall and are Macs. In other words, say 32% of desktops make it into landfills (more actually do; this article claims only about 14% are recycled/donated), half of them PCs, half Macs.
And as Macs become more popular, which I think is inevitable, and begin using more standard parts, which they already do, I think you'll see less and less of them ending up in landfills.
"... I got a whole pallet of Power Mac 75xx boxes for a dollar a few months ago..." Where? And do you want to unload any? Man, imagine a beowulf cluster...:-)

Good points, all. But even card manufacturers use different chipsets. And Macs are known not only for their initial price, but their resale value, which tends to hold up MUCH better than commodity PCs.
Plus, I'm one of those scary liberal types the GOP warned you about. Our disposable society generally sickens me. Our landfills don't need any more electronic components thrown in 'em. Build it right, and it'll last. TOC and all that.

This speaks right to the point, IMHO. VT may not have the time to put someone on the source to learn it. When a problem crops up, you usually need it fixed NOW; you don't have time for some coder to sift throught the source and try to figure out whats up. Are you familiar with ALL the source necessary to run a cluster of this size under Linux? Do you know anyone who is? Could you assemble all the coders/designers whos knowledge of the source might be necessary NOW to fix the problem thats shut down a multi-million dollar supercomputer cluster?
Reliability. No one in their right mind would try to argue that one couldn't build a home-grown system for less. But with optical ports? FW 400 and 800? Gigabit ethernet? USB 2.0? And with said home-grown machines, when the NIC goes bad in one, or a memory slot goes bad in another, who do you call? The NIC or mainboard manufacturer? So you what, keep a list of all your machines, give 'em i.d. numbers or whatever, itemize the guts and who made what (mainboard, NIC, RAM, CPU, HDD, etc.) of each, and hope to make sense of it all when stuff starts to fail? Me, if I was in charge of it, it would make sense to me to farm it all out to one company, and then when something breaks there is one number that I have to call. Also, lets not forget that this is probably going to be used for research, and if it involves vectors, then AltiVec is the SIMD for you.
64-bit only means that the CPU can use memory addresses up to 64 bits in length. Got nothing to do with general computing power. IPCs (instructions per cycle), Mhz, bus speed, cache size and speed, SIMD implementation - these generally determine 'speed'.
...Well that's what I mean. The record companies aren't fools - they obviously know it's easy to get around. Why don't the other online stores just do the same thing?...
They don't have a Steve Jobs doing the negotiating. Remember, this man is also head of Pixar, he knows his way around the entertainment industry, he's known to be a control freak, and if something goes wrong with the iTMS (broken DRM, for example), it only affects a miniscule amount of people. Look how quickly the kabosh was put on iTunes 4.0s' ability to share playlists via Rendevous. Of course, there's a workaround for it, but again, it seems as though the RIAA might be using Apple's small market share as a test bed for DRM'd online music sales.
Just my $0.02 on the matter.

You can with iTunes 4. And if I want to burn it to CD, I can select no gap between songs as well. My only complaint, I wish one could have different length gaps on one burn (i.e. set the gap between songs individually as well).
"...I watched the original version just after reading the book...I thought it was a steaming pile of shit..."

I did do an Observation/Conclusion thing, but this time I'll just make the observations and you can make your own conclusions.
I have only skimmed the thread, so apologies if these points have been brought up. Just seemed like everyone was "WOOHOO"ing without really looking closely. And similarity to other posts is just coincidence.
OBSERVATION: In the Activity Monitor window there are strange inconsistencies.

OBSERVATION: Why are the iChat windows censored totally? Why not just block them out like the Safari window?

OBSERVATION: No build number. Seems strange, since they'll most likely be giving out preview copies on Monday, and developers will want to know what build they're working with. If it's the final release, how did slip-ups like above creep in?
OBSERVATION: In the iChat window, it says "There is no camera attached to this computer." Yet the progress bar seems to be showing activity of some sort?
OBSERVATION: The Finder window named Xdrive is metal, but not entirely consistently. The metal has a bar down the right, next to the scroll bar, unlike Safari. This on its own is nothing that important, but the grow icon thing in the bottom right seems misplaced.
OBSERVATION: In the Mail screenshot, the "Working Offline" seems all wrong. Especially the "o" in working.
It just seems all wrong to me. I'm bound to end up with egg on my face, but I thought these items needed discussion.
