I'm reminded of a Lewis Black (a comedian for those who don't know) rant on how he found a Starbuck's directly across the street from another Starbuck's. His conclusion: They build them for people who have Alzheimer's, who upon walking out of a Starbuck's may say "You know, I could go for a cup of coffee," and then see one to go to immediately across the street.
3) Electrical/Communications: Across the bottom of the Unistrut standards, run surface mount electrical raceway aka Wiremold. Try getting the stuff that has 2 separate raceways - 1 for wire, one for communications.
No, no, no. Data Cabling 101: Never run communications copper parallel (when its not separated by a considerable difference) to line voltage. Any throughput you might have had will be shot to hell from the EMI generated by the line voltage. If your data cabling must be near your power cabling, use ONLY 90 degree crosses.
Oh, and make it out of non-conductive materiels. No, no, no. Conductive is your friend. You want static dissipation. Having a nice and grounded table is good.
Please read this. Quoting from there, "Not only is System X the world's fastest, most powerful "home-built" supercomputer, it quite possibly has the cheapest price/performance of any supercomputer on the TOP500 list." I don't feel like looking up the numbers... but as far as supercomputers are concerned, Apple is NOT expensive.
If you are skinny chick who only eats 1500 calories a day, why would you pay another $0.39 to supersize for a bigger meal with more calories that you don't need?
It depends on the customer. Someone who's saving their pennies, of course, would not splurge on the extra $50. Someone who's very concerned about the size of the device would not upsize. However, for Joe Average Consumer, $50 for 11 more gigs sounds like a good deal.
That's the thing though... when you're from Jersey, you don't necessarily know how Rutgers is viewed from outside. I've mentioned to people in other parts of the country that I go to Rutgers and I'll get responses like "Oh, the prestigious Rutgers," as if to say it's some sort of fancy/high-end school. And no it wasn't sarcasm on their part;).
Absolutely true. Rutgers is a BARGAIN for the school it is, and is often called a public ivy. Rutgers is also the oldest non-ivy institution second to William & Mary.
This summer, I found myself deciding between an IBM T series notebook and a Powerbook. The T series is nice. Relatively thin, metal, well made, etc. The Powerbook is thinner, metal, bigger screen, etc. When I spec'd the IBM similar to the Powerbook, the Powerbook was not that much more expensive. Also, the Powerbook has a bigger screen AND is thinner still AND had DVD-R available, whereas the IBM has/had (not sure of the DVD+/-R availability at the moment) none of those. I bought the Powerbook, I love it. I will never buy a cheap laptop again, it's not worth it. I have an HP from a few years ago. In its time, one speaker ceased to function, the motherboard fried (replaced under warranty), a hard drive might/might not have been bad (replaced under warranty before finally replacing the motherboard), the charging system completely failed to function (yes, I replaced the battery), one of the hinges tore the aluminum frame apart, so the screen would not stay up on its own, and last, but not least, the system will not boot at all, presumably due to a failure of the system to regulate its temperature anymore. On the other hand, I have an old ThinkPad from 1997 that, while thick as a dictionary, still runs absolutely fine, original battery and all. Dell laptops are horrible as well. My friend has one that reboots randomly very often. Every one we have at work has some problems (like random keys not working).
No, no it doesn't. Slashdot is NOT mission critical, far from it in fact. If Slashdot loses an article and associated comments, who the hell cares? See comments above for why MySQL is not Enterprise and/or useful for mission critical applications (lack of transactions, lack of relational integrity, etc).
I wouldn't say most debian users are running unstable. I run unstable on my TiBook and unstable on my workstation, but all my servers run stable. Important things in unstable are known to break. I haven't had stable ever break on its own.
Up until recently, MySQL had no transaction or atomic operation support. As such, you need to write application code to trap problems. Whereas with Oracle, when you run an atomic operation, you know without certainty whether the query failed in its entirety. I also believe stored procedure support is somewhat lacking in MySQL (however, there is that new Java function support). The MySQL 3 tree does not enforce constraints which is something most essential for data integrity. MySQL does not have subrow locking, whereas enterprise databases do. Once again, MySQL is great. I use it. However, it is not enterprise.
"Defect" is also a difficult term to define. Some errors are much worse than others. It's not all about numbers, folks. Don't get me wrong, I'm not saying that MySQL isn't a great product. I just get skeptical when I hear things talked about in terms of "better" and "best."
MySQL is not touted as Enterprise because its not Enterprise. Sure, it's fine for running Slashdot, but I wouldn't want it storing mission critical data. Oracle may be slower, but I'd much rather trust it to make sure my data is properly stored than MySQL.
Huh? It's interesting... because my iPod has nothing BUT mp3s on it.

I kinda meant what I said. When you underestimate, you don't recognize the full impact of something until the deficiency is fully realized. WordNet dictionary says "v 1: assign too low a value to" and that's what I meant.
Can't underestimate the importance of some news channel on at all times. During August of this year, we were in our NOC and we saw our power blip for a second and heard the UPS alarms from the adjacent machine room. Shortly thereafter, we found out we were on diesel power. Our monitoring tools began to show remote devices going down, some coming back, some not. I noticed my SSH session to home died around the same time. I began to worry. I called my house to see if my answering machine would pick up. No dice. It was at this point we realized a big power failure had hit us. A few minutes later, the reports started coming in on CNN that all of New York had gone down, etc. Eventually it all made sense, but it was definitely important to have CNN... even if we knew about the power failure before they did.
You don't want to use an RJ-11 plug in an RJ-45 jack if you plan on using the jack for anything requiring all 8 pins in the future. The incorrect size plug will bend some of the pins.
I'm curious as how they can limit a private party from suing a spammer. Tell me if I'm reading this wrong:
Amendment VII
In suits at common law, where the value in controversy shall exceed twenty dollars, the right of trial by jury shall be preserved, and no fact tried by a jury, shall be otherwise reexamined in any court of the United States, than according to the rules of the common law.

Alright, fair enough. It's just that the vast majority of installations use plastic wiremold, which, IMHO, is awful stuff.

Don't hold your breath. WINE does not work on Linux PPC. WINE is dependant on an x86 processor.

Well, the reason I mention version 3 is because it's widely deployed. Debian stable, for instance, is still on 3.23.49-8.5.

Six times better? I didn't know it was possible to quantify code quality in that matter. Interesting.
Then don't lie. If you advertise unlimited, it should damn well be unlimited.

Actually, it's probably a reference to war driving, which is a reference to war dialing.
