    • Yeah Bork Bork Bork is a language setting in the Google Preferences.

      Along with Elmer Fudd, Hacker and others.
    • It might be coincidence, but borking is also a term the Republicans made up, much like clymer.

      Judge Robert Bork was a candidate for (I believe) the US Supreme Court, and was generally believed to be quite accomplished. The ABA rated him as unqualified in what the GOP claimed was a politically motivated character assassination.

      So when someone is screwed over for political purposes, it's called being "borked."

      (Adam (?) Clymer, incidentally, is a reporter for the NY Times. George W accidentally left his mike on while remarking "there's that Adam Clymer guy, he's a real asshole," to which Dick Cheney replied "major league.")
      • Actually, while the term "Borking" is frequently used by Republicans to refer to character assasination, it was actually a left-wing lobbyist who first verbed the name "Bork".

        When Bush The Elder appointed Clarence Thomas to the Supreme Court, Florence Kennedy, then president of the National Organization of Women told the press, "we're going to Bork him. We're going to kill him politically." Shortly afterwards, Anita Hill came forward to accuse him of sexual harrassing her several years earlier.

    I have a 700Mhz radion iBook, so as soon as I saw this story I rebooted and made the change (it's not so much a script as a list of firmware commands, you have to copy it out or look at them on another machine and enter them by hand). I'm now typing this in on my 21 inch Sony trinitron running at 1600x1200. Works great!
    Gotta wonder, though. Apple really has limited the use of this radion chip. They disable this, and it only came with 16 megs of vram. Chip supports up to 64! If it only came with 16 more, it would be a pretty able 3d card (not that it's terrible now, just somewhat underpowered). How much would an extra 16 megs cost?

      Apple can't make the iBook too good relative to the PowerBook G4, or it's low price would cannibalize sales from their premium laptop. That's why monitor spanning is disabled and they only put 16MB of RAM in it.

            A "good" business puts out the best products for the lowest prices possible. If it would only cost a few buckazoids to add another 16MB of memory to the iBook, and it would make it a far better product, then to be considered a "good" company they are *obligated* to do that. Otherwise, they are LIMITING THE PERFORMANCE FOR MARKETING PURPOSES, IGNORING A WAY TO MAKE A BETTER PRODUCT FOR LITTLE EXTRA $ IN ORDER TO INCREASE SALES OF THEIR HIGH END PRODUCT.

            Pick prices ranges. Make the best products you can, under those price ranges. do not ignore ways to improve one product in order to increase sales of another. That is the only way you can call a company "good"

In it, they said something about DVD Player freaking out, but I don't know if that is in reference to the known problem of the TV out issue or something else. I didn't have a chance to run the commands this morning before work, and wanted to wait to here from other reports before doing it.

      Anyway, if you have any anecdotal information regarding side effects, it'd help those of us who haven't done anything yet.

      • Err... You're kidding right? I've used both, but own neither :-( but given the choice I'd have a PowerBook G4, why?

        It's a G4 (obvious I know) but that's quicker (if you do video on it then it's LOTS quicker.

        It's got a bigger screen (and it's a laptop - you won't be next to a display all the time will you? {if the answers yes - get a PowerMac!})

        It's thinner.

        It can take more RAM.

        It looks nicer. (ok maybe that's subjective)

        The G4 PowerBook will last you longer (unless you drop it) as it is a better machine to start with. (So you'll feel the "upgrade itch" later)

        Dude, the G4 PowerBook is one, nice Mac, sure the iBook is nice too, but the PowerBook usually has the edge. (Ok, when doesn't it have the edge? When money's short {duh} or when you want a REALLY small machine to stuff in a small bag)

        Yeah, this is nice for anyone who has an iBook (assuming this actually works properly long term) but it hardly devalues the PowerBook. (Anyway the PowerBook has a certain prestige)

        • Err... You're kidding right? I've used both, but own neither :-( but given the choice I'd have a PowerBook G4, why?

          I had the choice, and I opted to get the iBook. My primary reason is that the iBook runs a lot cooler. I also have found that the iBook (14.1-inch model) has slightly better battery life than the TiBook.

          Both the G4 and G3 processors are excellent for a laptop system, but I'm a big fan of G3 laptops.

        • actually, no, i'm not kidding. i've used both, and for the most part i use my powerbook for aim, the 'net, and email, ect. the most cpu intensive application i've probably used in the last week was itunes (which runs continiously). i like the durability of the ibook more, as i'm a college student, and actually, the laptop sits next to a 17" NEC multisync @ 1600x1200 99% of the time, except when i go home about every other weekend. oh yeah, and the ibook's fan wouldn't come on nearly as often when playing music. i only have half a gig of ram in my PBG4.

          besides, if i got a new ibook, it'd have more vram than my tibook (16 vs i think 32), so i'd be able to run the external display w/quartz extreme.

          The majority of the time I'm using my iBook, I have an external screen available. When I'm out and about, the ability to fit easily into my pack is more important than the size of the screen (the reduced width of the iBook is more significant than the reduced depth of the Powerbook).

          >It can take more RAM.

          I don't have my iBook maxed out anyway, so this isn't an issue for me.

          >It looks nicer. (ok maybe that's subjective)

          It is. I prefer the iBook look, as does my friend with a Powerbook.

          >The G4 PowerBook will last you longer

          Maybe. But with a laptop half the price, I can afford to replace it a lot sooner.

    I realize that it is probably a hardware hack, but if anyone has ever done this I'd be interested to hear. One of my major reasons for not getting a Mac is that I can't justify (afford) a G4 standalone, but I don't want two monitors on my desk unless I can use both of them simultaneously.

      • For some people, that would probably work fine, but not in my case. Essentially, what you are talking about is using the iMac as a terminal to connect to whatever other machine.

        At that level, I might as well just run VirtualPC (OK, well, it might not be that bad). Essentially there are two reasons a VNC wouldn't solve my problem: (1) I already have hardware I don't wish to get rid of (i.e. 19" CRT), and (2) I wouldn't want my use of the PC to be limited by problems/bottlenecks over the LAN and software issues on the Mac. In essence, I want to do what Gamgee5273 suggests, i.e. plug the Mac into a KVM and use it as an external monitor.

        Thanks for the creative suggestion though...
    • The CRT iMacs (or, at least, the early ones) had a standard VGA connection inside the case. That led to some folks snaking the connector out and setting up a KVM.

      If the new ones have some sort of standard connector, then it could be done (disconnect the monitor from the board, run it to a KVM, run the KVM to the board...). I would dig around and see if you can find some screenshots of new iMac dissections...

    The term "Monitor spanning" does not apply to macintoshes since you are NOT spanning one screen to multiple monitors.

    The correct term is "multiple monitor support" because the macintosh has been built with support for multiple monitors from day two.

      The problem is that "multiple monitor support" is an ambiguous term. The iBook has multiple monitor support - you can plug in a VGA monitor and have it display the same thing that's on your built-in display. In Apple parlance it's mirroring, but technically it is still multiple monitor support.

      On their web site, Apple has referred to monitor spanning as both "extended desktop" and "dual display".

      While the two 2MXs look quite the same, and both have analog (VGA or HD15) and digital (ADC) connectors, they are quite diffenrent from "inside". The 32meg version can only push identical video to both connectors. On the other hand the 64meg TwinView can support two simultanious monitors (screen spanning) - hence the name.

      What I don't know though could the 32meg be hacked to support screen spanning. This depends on the internenal structure of the board. Most PC's 2MX cards cannot be modified, as the hardware is built that way. (Of course they have DVI instead of ADC, but that changes nothing.)
