  1. Re:The hardest math on Major Advances In Knot Theory · · Score: 4, Insightful

    I think the important thing is that when you're investigating new areas of mathematics and it's _hard_, that's because the tools you're using are not suited for investigating this issue. So you invent a new tool, and that new tool can be applied in many, many places.

    Hard problems are only hard because we're using the wrong tools.

  2. Re:Ummm.... on Casting Doubt On the Hawkeye Ball-Calling System · · Score: 1

    It's not fully accepted in football ultimately because of the issues of ensuring the system could withstand the impact of being kicked. Bear in mind that these tiny tennis balls reach speeds >100mph; a system has to be able to withstand that impact.

    With hockey, I imagine that the puck is solid makes it simpler to ensure the integrity of the weighting of the puck after impact than it would be with a hollow tennis ball. Striking the relatively light and soft tennis ball to high speeds deforms the ball significantly and making sure that the radio system or whatever you pick remains both functioning and not affecting the balance of the ball would by a challenge.

    Something else that comes to mind is that with a puck, you can scoop out puck material equal in weight to the broadcasting device. With a football, there is significant mass relative to the broadcasting device. A tennis ball is both light and small, meaning that it is difficult to make sure that the ball with the broadcasting device inside it is the same weight as the ball without the broadcasting device inside it. All of this comes down, really, to the fact that a tennis ball is small, hollow, light and struck with enormous power.

  5. Re:You don't have to be Kreskin on FreeBSD 7.0 Bests Linux In SMP Performance · · Score: 1

    The reason I started using FreeBSD was because I went to the store and bought a wireless card, a linksys something or other. I got home and SuSE couldn't detect it. Neither could Ubuntu (this was around the days of Ubuntu 5.something) nor Debian. I had a friend who was a FreeBSD nut who walked me through the install and my wireless card worked straight away.

    Whether desktop drivers are a good metric really depends on what hardware you own. Sometimes what you need just ain't there.

  6. Re:You don't have to be Kreskin on FreeBSD 7.0 Bests Linux In SMP Performance · · Score: 3, Interesting

    Well, I don't think I've ever installed any package from anything other than the ports system. Lots? I know I've installed everything from Gnome, XFCE and KDE, through OpenOffice and a bunch of stuff in between.

    You're right that mere numbers of packages is a weird metric, but what else can we offer? FreeBSD has great performance, and has everything necessary to be either a good server *or* a good desktop. It's much like Gentoo that way -- it doesn't focus on being either one or the other, it focuses on being a solid basis. What you put on top of that basis is your choice. It honestly seems to me that the distinction between server OS and desktop OS is its own entire discussion; if we can come to a good notion of what either means, we can reach a nice conclusion. If we take the current crop of Linux desktop OSes, though, I don't see any more integration between, say, Fedora and Gnome and FreeBSD and Gnome, or Ubuntu and Gnome and FreeBSD and Gnome.

    If I think about it, it does seem that Ubuntu starting with a GUI interface and letting you find the command line by yourself is more friendly to the average user; I haven't installed FreeBSD using anything other than minimal-install for so long that I don't know whether you can have a GUI start up by default. And FreeBSD's installer, whilst excellent for its audience, is less friendly to a first timer. If we take those metrics, the idea of "can I sit down and first time use it without documentation?" then a lot of the linux crop are friendlier, yeah. But the documentation *is* very hand-holdy, and very very thorough for FreeBSD. And nicely available online.

  7. Re:BSD Desktops on FreeBSD 7.0 Bests Linux In SMP Performance · · Score: 1

    Gnome in FreeBSD is at something like 2.20 -- pretty damn recent. Just install FreeBSD, and either use pkg_add to grab the most recent binaries or build your own gnome by grabbing the latest ports tree ("portsnap fetch extract"'ll do that ) then "cd /usr/ports/x11/gnome2 && make install clean". Done.

  8. Re:You don't have to be Kreskin on FreeBSD 7.0 Bests Linux In SMP Performance · · Score: 3, Interesting

    You think so? I dunno, it seems to me that FreeBSD suits the desktop role really well; I use it for preference. Especially when you consider that the only OS with more packages is Debian, it makes sense that it can fit a desktop role extremely nicely.

    The RAM that comes with the laptop as standard is different. You have to upgrade to the 667mhz 2dimm to get the same as the pandolin. That's an extra 425 dollars.

    I know this'll sound trolly but I wanted to throw this out so you know it's an option. There's always BSD. I've been expanding my *nix experience into the BSDs because it gives me the options I need in case things go sour in the linux world. The installers are completely opaque for FreeBSD and OpenBSD, but once you get used to them somewhat it starts to feel good to know your options.

    I just configured those two systems per your specs. The system76 came out at $1474.00 US and the Dell came out at $1773.00 US. I'm assuming that the biggest difference was the graphics card, so I fooled around with http://system76.com/product_info.php/cPath/1/produ cts_id/165 instead of the pangolin. Dell wins at $1773.00, but the serval wasn't trailing too far in price at $1774.00

    Bear in mind that the Dell wasn't actually coming with the Complete Care you said you received. If I add that, the Dell comes up to $1872.00.

    Now, the Dell at that price *is* coming with a bigger hard drive and a better battery, so it's definitely not comparing apples to apples here, but I'm honestly not seeing the prices you're saying you received. Was the laptop on sale when you bought it, maybe?

    I want to start out by saying that I don't actually think Microsoft's Office suite is inferior in any way to OpenOffice.org - it's a by far superior product right now. I should clarify: the questions I was answering were yours, not the OPs, though I understand that their stuff provides some context. Also, your keyboard example is a weak straw man at best. Let's not confuse the issue by trying to argue by analogy.
     
      Now, whether or not you believe it to be so, I actually think that if I were running a business of, say, 100 employees and I have the choice of paying $75 per seat, a total cost of $7500, or of telling my employees that we were running OpenOffice.org and they just had to learn that the comma wasn't appropriate in Calc, it's a semi-colon, at a total cost of let's say $25 lost in "mistake time" to my payroll, I know what I'd choose.
     
    As you've already accepted that there's a retraining cost with Office 2007, though, then really speaking what comes in to play is the performance issue that you've pointed out here and in other places. You've said that OOo simply takes a lot longer to do basic stuff vs Office 2003. However, I haven't seen the blow by blow for how long Office 2007 takes to perform these same things on the old hardware. If it's like the new version of windows and there's an outright hardware upgrade needed to get a responsive application, then I'm afraid OOo is the winner there. A rising tide carries all ships, after all.
