In a quick search, I wasn't able to find anything generic, but in my experience (with VxFS), journalled filesystems work by a small, circular intent log. Updates to the superblock (inode changes) get logged in the intent log, and then the change to the inode is pushed to disk. The intent log is usually one meg or smaller.
Journalled filesystems only log the metadata changes. They don't log data changes. They're intended for use in speeding recovery, and they're not a silver bullet against data corruption. If the data in the block or extent is toast, no amount of journalling will save you.
DAoC is $13 a month. So to say that it's 50% more expensive than "every other MMORPG" is simply exaggeration. And certainly, the choice to play an MMORPG is the player's alone, however, people who choose to play CoH no longer have the excuse of, "But The Mob of Uberdom only spawns once every 15 hours and we have to get in line to kill him!" like there was in EQ.
The CoH developers did everything they could to eliminate timesinks and make the game playable by more than the hardened time warriors. The point is that it's possible to play the game *and* spend time with the girlfriend, as opposed to the "all or nothing" short-sightedness that the story submitter calls a solution.
If you're playing 12 hours a day, or getting home from work, jumping on the PC, and completely ignoring her day in, day out, I can see her having an issue. But that's not the impression you give.
What?
That's exactly the impression he gives, when he writes about "gaming all the time". They play the game, they ignore their girlfriends, and then wonder why the girlfriends get mad.
One of the bonuses of City of Heroes is the lack of EQ or DAoC-style timesinks.
You don't have to level your character before leveling your clothes. You don't have to camp a spawn for seven hours. You don't have to do ML10.
The game is perfectly able to be played an hour or two at a time. In fact, it caters to casual gaming. If you're spending so much time playing City of Heroes that your girlfriend is getting pissed, there's probably a good reason.
Because if you rear-ended someone and the airbag went off, that'd be 15" of LCD straight into her face. And as I'm sure you're aware, glass and eyes don't get along very well.
If you're a sysadmin nerd, it's sort of a given that if you have two sources accessing the same filesystem at the same time, you're going to clobber your data. (That is, unless special protection is used.)
Maybe Apple just wanted to prevent people from screwing up their iPods.
You will need to reformat your iPod from the HFS filesystem it uses with the Mac, if you want to use it with Windows. Newer iPods support old-style USB, but it's slower than dirt.
The interface is "wacky" because of Microsoft's Multiple Document Interface. Apple's interface is quote as follows: The application itself does not have a window, and its presence is visible to the user only in the display's menus and menu items. More reading on the subject can be had here. In short, Apple's using the same interface they've ever used.
QuickTime is installed because of Rendezvous, I think. I'm not an expert on it, but Rendezvous uses QTSS (QuickTime Streaming Services) to stream your playlists to your network. Even if you had QuickTime installed, you didn't have QTSS installed.
I suppose it depends on a given definition of hack.
I have a Series2 DirecTiVo unit, which is happily humming along with a 120-gig hard drive. The original 40-gig is sitting in a closet.
One thing that they have done is make it impossible to install a downloaded version of the OS from another Series2 DirecTiVo. The solution to that is simple - create your own backup and/or save your original hard drive. Personally, I've done both.
No, you can't dig around in the filesystem or change the kernel. Theoretically, the things that got changed in the kernel (TiVoWeb, etc), will be obsolete if the software updates that were promised come through. I don't understand what all your belly-aching is about.
I spent weeks swapping emails with customer service, who asked me to re-install DirectX and other assorted useless things. I eventually decided that I would be just fine with playing Dark Age of Camelot's expansion, and that really, it wasn't life or death if I didn't play TSO.
So much hassle for a game I probably would've hated anyway.
Besides, if you've got DirecTV and their Total Choice Premier package, the TiVo subscription fee is waived. (Or, included in the package, if you prefer to look at it that way.)
Either way, a TiVo subscription for a DirecTV DVR is all of $4.99 with their less-inclusive packages. If you can afford a TiVo, you can afford $4.99 a month.
Only with certain versions of the software, and with certain hardware.
With newer versions, and units such as the Series2, the unit will go into "boat-anchor mode" (their terminology) if the unit has not been able to make a call for about a month. At that point, you can watch what you've already got recorded, but not much else.
They do support broadband, in their Series2 DVRs. There are USB ports, which you can hook up a USB->Ethernet adapter. Once you've done that, you just give a different dialing code, and it grabs an address via DHCP and does all its downloads over your broadband.
There's a bunch of information on how to do this if you do some searching at http://www.tivocommunity.com.
When you can also write some neat front-end software for it that provides for all of the TiVo features (too many to name here), and can still bring it under $200, I'll think about it. But only if I don't have to be a sysadmin to use it. I'm a sysadmin enough at work; I want my PVR to not require an intimate knowledge of the command-line.
Oh, and don't forget to package it in a nice little black (or silver) box that fits within my entertainment center.
We won't even get into DirecTiVo here. Mmm, Dolby Digital.
I take it you haven't really looked at the specs for this integrated chipset.
While it's convenient to think that there are two and only two groups of users - the ubergamers, and the drooling morons - this isn't the case. If it were, there would be two, and only two, cards on the market. The "eke out 3 more fps in Q3A" card, and the "maybe it'll play The Sims" card.
These integrated chipsets have a lot of nice features, including digital 5.1 sound. It's essentially like having a GeForce4 MX (a card I have in my machine at home) with a good quality sound-card - only, two fewer cards to buy.
Not everyone likes having a mess of cards in their PC. Not everyone needs bleeding edge. Lots of people are perfectly happy not having the latest-greatest.
It's a huge update, but since you just bought your PowerBook, you qualify for the "Up to Date" program. There should be some documentation on how to use it, that came with your PowerBook.
I am completely anomalous. I started out your typical paid-for-crap ISP sysadmin, and worked my way up from there. I found zero use for certifications or the like. I attempted going to a small school near me, but I quickly realized it was a waste of my time and money. (When the professor said, "OSI? It means, uh, ISO backwards" I realized it was time to get out.)
College is good in a respect, I suppose, in that it encourages you to better yourself. I'm continually growing as a sysadmin, and I went from working a crap ISP job to working at places like Netscape and Wells Fargo, administering large Sun Enterprise systems. It came from always asking questions, always reading and researching, and always picking peoples' brains. If you have the drive, you'll succeed either in college or in the job market. The hard part is finding someone who'll take a chance on you. (I did find those people, at the right times, which is why I consider myself to be successful now.)
Technically, I'm not a systems administrator anymore. I did get burnt out on sysadmin work. ("Great. I've been a senior sysadmin at Netscape. Other than management, where else can I go now?") However, I never lost sight of the "forward momentum" needed in the IT world, and took a job that will make me a much better sysadmin, should I ever go back to it.
Point being - you'll learn in college, or you'll learn on the job. The two aren't that different, but how you handle it will be.
I used to work for Netscape, in Netcenter. AOL forced AOL accounts on us, and forced us to use said AOL accounts for all kinds of things, up to and including change control for new system installs, and the stuff that was previously mentioned that you declared was "bullshit".
Just because we hated to use it, doesn't mean we weren't forced to for some aspects of the business that you might never see. Did I publish my AOL address? Hell no. Did I have one? Yes - and I had to log in to it with a SecurID token and everything.
Honestly, you got me. I don't deal with Oracle at all, just the systems themselves. (I suppose I should learn about Oracle, but that'd require that pesky training that there never seems to be a budget for.:)

Yes, there's a buy online button. But that's used to get info so one of their sales droids can contact you. It's not like you can slap it on your Visa card.:)
(Disclaimer, I work a lot with E10Ks, so this post is written mostly from my experience with those.)
The 15K is basically just an improvement on the E10K architecture, from what I've seen and heard from Sun's SSEs. The E10K started out life as the Cray SuperServer, and was sold to Sun for a song. It's not architecturally perfect. The E10K is set up to allow individual system boards to be part of domains (aka partitions), which can make for some great scalability in the domains. I've seen tiny little one-system-board domains, and domains with 13 fully populated system boards in them.
One of the major advantages to this platform is the fact that you can hot-swap everything except the centerplane. (Of course, I've never seen a centerplane fail.) The E10K also has Dynamic Reconfiguration, where you can remove system boards from a running domain, but unless your platform is set up in a certain, specific way, this doesn't work as well as advertised. I've personally never used it. The best thing about the E10K is the use of the System Service Processor, which handles all the administrative tasks for the entire cabinet. I've heard that the SSP is now integrated into the 15K, thus eliminating the need for a separate system to perform these tasks and monitoring.
The only thing I've ever seen this class of system used for is data warehousing. No modeling, no graphics rendering, just Oracle databases. Just because it has a large number of processors, doesn't mean they're going to be suitable for every task imaginable. (I used to have a 180MHz Indy R5000, that got 68kkeys/sec in d.net. My 166MMX got something like 350kkeys/sec.) These are workhorse processors, not sports-car style processors.
Though I wonder if Sun's gotten around to fixing that nasty ecache parity error problem with their processors... Having a domain randomly crash because the parity bit on a processor got flipped is no fun when you're dealing with a large production database. I have a feeling that problem will continue to plague them in the 15K.
In 1999, I contracted at SGI for a few months. Since I had an Indy R5K with a webcam, I took the opportunity to post a little "Ciannait's office" page on reality.
Ever since I contracted there, I've been known to reference The Annotated Aerial View of the Cray Research Park as evidence that yes, I worked there. I was in Building F, in the supercomputing department.
Despite my waste of bandwidth site on reality, the creative and intelligent people at SGI used it for all sorts of things. SGI folks are demoralized enough as it is, and I feel for them, considering that this resource is being taken away. What's next, the end of Ducky Day?

Well, the service is actually incredible. Have you used it? There's so many features, I can't get into a lot of detail here.
Essentially, a TiVo without the service is about as useful as a VCR. Which is to say, not terribly. The service is worth the money.

Apple's OpenFirmware and Sun's obp (OpenBoot) are essentially the same thing. I don't remember who got which from whom, though.
According to this, the new nForce2 chipset features either a GeForce4 MX or a GeForce2 MX.
