ZFS won't give you good performance for a large array because your random read speed is basically limited to the equivalent of one drive per raid set. That is unacceptable if you need performance
Cheap, reliable, fast: Choose two.
Cheap + Reliable: RAID-Z and cheap drives Cheap + Fast: Stripe on a non-ZFS filesystem Reliable + Fast: ZFS mirrors on good drives. Go a step further, add L2ARC on SSD (readzillas).
You can't have your cake and eat it too. That said, RAID-Z and RAID-Z2 perform quite well for most people. I like the data integrity ZFS offers, but that's just me. I'm done with traditional filesystems and volume management.

hardware raid really is a must if you have a lot of storage
No, hardware RAID is a bad idea. You're locked to a proprietary controller and a proprietary on-disk format. ZFS is a much better idea.
To get proper care you either have to stump up cash per treatment or purchase insurance.
Are you claiming this is a bad thing? This is how it should work. Things cost money. You can either a) individually pay for these things or b) get together with a group of like-minded people and pay a little bit at a time so none of you will ever have to pay out a lot of money at once (we call this insurance).
I don't want to pay for people's things that choose neither (a) nor (b).
If it's impossible to provide the treatment to the garbageman, it's wrong to provide it to the billionaire.
That's one of the most unbelievable things I've ever read. Some people have money. How they spend it is not your business. The only reason things ever become affordable for the "common" person is because someone who has a lot of money goes out on a limb and tries it first.
If I browse adult stuff at work on works PC and Internet connection, work can be held libel. If I browse adult stuff on the iPhone at work using my own Internet connect, it is less likely that work can be held libel.
I think you mean liable. Libel is something different entirely.
In any event, it's easy for corporations to disable USB and Bluetooth use. Having a phone with tethering capability is a non-issue.
The one thing ZFS won't have is hard linked directories, which is needed for time machine.
ZFS out-time-machines Time Machine. Very good snapshots are available by default. OpenSolaris implements something known as Time Slider which provides similar features. Really, Time Machine would have been easier to implement in the first place if they switched to ZFS with Leopard.
But I've got a 2G iPhone and about a year left on my contract (waited a while to activate) so if these people get their way, you won't see me complaining.
You're in luck. If you have a 2G, you can pay the discounted price for the new phone. This is because the 2G was not subsidized, so AT&T isn't losing anything by letting you upgrade early (basically 2G -> 3GS upgrades are being treated the same as 2G -> 3G upgrades). I have about a month left on my 2G contract and I went to preorder and it offered me the discounted price.
Why bother? The apps are there to get work done, not to work pretty.
Completely disagree. Form is part of function. My latest frustration was using one of the Dust themes for GTK. Hey it looked not half bad... but whichever variant I was using had no texture/color variant between the toolbar and the actual window of the app. This is what I wanted because it looks nice... only to find out that it makes things a pain to drag because there is an invisible line above which clicking and dragging a window is possible, but below it's not possible.
Has nothing to do with distribution. Here's my desktop OS history: Windows until 1997. Full-time Linux from 1997 to 2004. OS X: 2004 (after Panther was released) until present. I want to run Linux on the desktop. And I even ran it on a PowerBook G4 until Panther came out. I recently tried to see if I could switch back from OS X to Linux. Not going to happen. Half of the apps I want to use are GTK, half QT. I don't want to spend the time to try to get them to look similar. I really wish I could use GTK full time, but, it's really ugly and unfriendly.
As it stands, there is no end all be all. I will continue to run Linux on servers, but it's unlikely to be my desktop. I'll run OS X as my desktop, but I see no compelling reason to put it on a server.
Like every other Geek and Nerd, when I do the social skills stuff, it limits my technical skills stuff.
I would completely disagree with this. Having good social skills helps me to communicate my technical ideas to all sorts of people. This includes explaining complicated subjects to people with less technical knowledge in a way they can understand. It also means being able to ask intelligent questions and communicate with equally technical people.
There is not an inverse relationship between technical and social skills. Anyone who thinks so has probably not read any of Knuth's books. Here we have an example of the most brilliantly technical individual being able to express ideas in the most coherent way imaginable, all the while injecting humor and not making material dry. That is certainly a combination of technical and social skills.
In the past, I had some professors who were truly masters of their field. Some of them were not so good at communicating, but others could teach and interact at a level which made it obvious to see how well respected they were.
they got so many appreciative comments on their documents that they would use LaTeX again
I think this is a subtlety that most people don't understand. When I see [La]TeX documents, I will comment on their appearance. When I interviewed for my current job, one of my interviewers noticed LaTeX as a skill on my resume (properly formatted by using '\latex', of course) and also commented on how nice my resume looked because of it.
I sent my resume to someone recently and one of the first things out his mouth about my resume was "Did you do this in TeX?" My affirmative answer resulted in a laugh and the comment "well, it makes for beautiful text."
Never having met either of them before that, I wouldn't have expected them to notice this, but they did, and it made an impact.
I don't know anyone that's actually allergic to toner, but you can sure as hell smell it in the air!
You're not smelling toner, you're smelling ozone due to the corona discharge inside the copier or printer. It's also common to smell this when it's raining/thundering as lightning generates it as well.
More important, and I've had this conversation again and again with decision makers, is that the Master's degree is the new Bachelor's degree.
Maybe you were speaking with decision makers in companies who don't know how to hire people, but this is stupid thinking. There are plenty of people in very technical fields that have nothing beyond a BS and it hasn't hurt them at all. Smart people are smart people regardless of the degree they have. Your degree means next to nothing after your first job of consequence. The only people who will ever claim something different are ones who use their degree as a crutch. I say this as someone with a degree from a well respected institution, not a high school dropout trying to justify not going to college.
Or...I dunno, maybe they could create a filesystem specifically for NAND flash.
It makes much more sense for existing filesystems to include awareness of SSD and use them accordingly. ZFS is doing this; eventually others will, too.
Actually, routers might be a good match for SPARC. A processor that can handle comparing/transforming/etc ipv6 addresses in a single instruction and handle a high number of threads might actually be a nice match for a certain type of high-end router that has to do a lot of filtering.
A lot of routing is done in silicon; that is, it's done with TCAM which provides for O(1) adjacency lookups which are very good for routing/switching.
Except that WSJ is the model he's basing this on. They offer some content for free, but many of us pay for full content. This is in direct contrast to what Murdoch originally planned which was to make wsj.com fully ad supported. Murdoch has pulled a full 180 and I think he's made the right decision.
I agree with the points that those companies using the Caymen islands as a tax evasion deserve to be fined and taxed on profits.
Except that it's completely legal in many cases. In order to fine them, you'd be advocating some ex post facto law which is just plain wrong. Why don't you maybe complain about the Congress that wrote the laws than the people that are following the law as it stands?
Somehow I find it hard to believe that those 18,000 corporations in one building do the majority of their business in the Cayman Islands.
Somehow I find it hard to believe that you actually believe if we make it illegal for them to do this (and therefore force them to pay more US or EU tax) that the cost won't be passed on to consumers. How naïve. Here's a simple principle for you: more tax is never good. Never. Never ever ever. Never. It's pretty easy to understand.
Abolish the 16th (and the idea that government owns and what you make, deigning what % you can keep yourself) and use something like apt-tax which is effectively an excise tax on currency as I understand it: http://www.apttax.com/
And what about when they change the tax code every year? Do I have to do 'apt-tax dist-upgrade' every April 15?
Because a good switch will be able to tell the MAC address of the computer plugging into it is not authorized, record the attempt, and turn off the port.
Where did people start getting the idea that MACs are both secret and immutable? I can sit down at a desk with port security (Cisco's terminology) turned on, look at the back of your PC and read the MAC printed on most PCs near the serial number, and then tell my laptop use that MAC. I unplug your PC and plug in my laptop and your switch doesn't know the difference. Nice try, though.
A client certificate is pre-installed via a known secure method which makes man-in-the-middle attacks moot.
The Apache vulnerability is not related to the issue at hand (e.g. 802.1x with EAP-TLS). Vulnerabilities can exist in all sorts of security mechanisms. The advantage with client certificates is that as soon as you know of a vulnerability, you can fix it and publish a Certificate Revocation List that would prohibit potentially compromised certs from being used on the network.

So let me sum it up... 1) No accountability 2) Not a team player and too good to help others and 3) Not willing to interact with non-technical people.
Okay, then! Remind me never to hire you.
Nice thing is that it's still probably cheaper than getting a drobo.
And not a black box...
And not locked into one vendor...
And not bound by the speed of USB or Firewire...
Yea, I'd say ZFS is the way to go :-)
