  1. Re:Why a Laptop? on Laptops Required for Freshmen · · Score: 1

    1-I wouldn't want to take my laptop in my bike bag every day, I don't think it would last long. I ride some pretty rough roads in places.

    2-I'm not sure why I would want to have my personal laptop at work; the only use I can think of is to waste time. I like to spend my time at work doing work so that I can go back home again.

    3-We're not allowed to attach personal devices to the network at work. I thought this was pretty much standard these days?

    4-On occasions where I do want to get access to or use home computers from work, that's what VPN is for. Why would I carry the computer and risk damage/loss when I can just access it remotely?

    Those things are the bane of fire departments. They can fire up, start to move, pretty much anything while they're trying to extract you from the car. Std procedure now is to not attempt an extract until they find the fob and get it the hell away from the car, then hit the battery disconnect (assuming they can get to it).

    Talk to a fireman sometime. If they want to get in to a place, they usually totally avoid the door and go through the wall next to the door. It's usually just a piece of 1/2" plywood and 1/2" drywall with some pine studs and siding. You can get through it pretty fast.

  4. Re:Laptops don't help in lectures, but... on Laptops Required for Freshmen · · Score: 1

    I agree. Plus, I have many things which my pen and paper can do which the computer can't. Pen and paper are the most flexible, intuitive and stable recording device we have. I've never had my spiral-bound notebook crash and lose all my notes. I've not seen the word processor that lets me copy down drawings and graphs from the board without a ton of hassle, nor one that allows me to quickly jot reminders, or questions I thought of and want to ask the instructor at the next break, or cross-references to other parts of my notes via arrows in the border, etc.

    It may be possible that all that is doable, but can you do them without distracting you somewhat from the lecture?

    You can buy really a pretty nice notebook from Dell for $449. If you can't afford that as a one-time expense for your whole college career, it's unlikely you can afford to attend college in the US at all.

  6. Re:I'm not convinced on Laptops Required for Freshmen · · Score: 1

    I found that writing with pen and paper was an excellent study aid. I can pretty much type what people say without even absorbing any of it; I sometimes take minutes at meetings with a laptop, and at the end of the meeting I sometimes have no idea what they were talking about. But with pen and paper I actually absorb what is being said. Also I can copy diagrams and cross-reference (draw arrows around, etc) free form in ways that I just can't on a computer.

    Honestly if I were to go back and take classes now, I'd use the laptop as something to hold my paper up with.

  7. Re:Why a Laptop? on Laptops Required for Freshmen · · Score: 1

    OTOH, I bought a laptop because they seemed so cool and useful, and I pretty much never used it. Apparently the ability to actually walk the hell away from the computer and do something unrelated is not needed anymore.
    I do use it now, but it never moves. It's pretty much bolted in place by all the wires going to the peripherals that you can't get built in to laptops (multiple hundreds of GB of drive space, video digitizers, film scanners, real keyboard and mouse, etc.etc.). I could have saved about $1500 and got a new desktop machine.

    I do take it on vacation, but I pretty much only use it as a storage point for my digital camera. I could have bought a $120 external hard drive that would do that without needing to carry the laptop and all its crap.

    Every way except being able to play it or anything. I'm not going to go buy another player so I can play a different format when I have no problems with MP3. I'm also not really hot on seriously limiting my choices of players because I'm stuck on using a non-mainstream format.

    I understand that Ogg is technically better. Lots of technically better solutions die. Ogg has had what, 5 years or more to make its mark, and it's still a backwater, supported only really as an afterthought on a couple of manufacturer's players.

  13. Pretty high on Another Ars Ultimate Budget Box · · Score: 1

    A friend at work bought a Dell laptop that seemed pretty capable just before christmas. It seemed nice, had a good looking screen, built-in wireless, a CDR+DVD-ROM combo drive, and XP home. He paid $499. It was about $575 with shipping and everything.

    If they can sell a laptop for that, I'm sure a modest desktop could be a lot cheaper.

    I built a pretty decent machine for a friend last year. I think the total was around $400 with a legal Windows. It had 256M RAM, a CD burner, and a 17" CRT monitor.

  14. Re:coal on New Nuclear Power Plants in the next 5 years · · Score: 1

    Coal byproducts aren't radioactive.
    Of course they are. The difference is that with a nuclear reactor, the radioactive materials are retained as waste and properly contained. With a coal plant, the radioactive materials are released into the air for you and I to breathe.

    Coal plants don't have a nuclear waste disposal problem, but that's not because they aren't producing any, it's because they just flush it into the environment. Along with a bunch of mercury and other crap.

    I'd take 10 nuke plants in my county before I took one coal plant. I grew up within 20 miles of two plants, and nobody that I knew had any problems with them being there.

  19. Re:Prius owners are as selfish as Hummer drivers on Has World Oil Production Passed Its Peak? · · Score: 1

    While I think you're full of it (reducing your impact is good, even if you can't eliminate it) I will say that I'm not terribly fond of hybrids. They tend to be overblown toys, with lots of computers and blinking lights and crap, and the mileage they get is NOT tons better than you can get out of other non-hybrid cars. The VW Golf TDI can get > 50 MPG and cost so much less than a Prius, and has so much lower of an impact during manufacture that the Prius really doesn't look very good in comparison.

    I did the numbers last year when gas was > $3/gal, and just in terms of economic payback, the extra mileage of the Prius compared to a Golf TDI, and even considering that currently diesel costs more than gas means that you'd have to drive it > 850,000 miles in order to break even on the extra cost of the Prius.

    However, the main reason I don't like SUVs has nothing to do with their fuel consumption. SUV owners tend to be self-centered jerks who don't give a crap what happens as long as they got theirs. Take a look around at who are the bad drivers on the road sometime. SUVs are proven to be more dangerous both to people inside and outside the vehicle, but by God, people gotta look up to you if you're drivin' one of THESE babies! HA! Nobody will laugh about my...never mind.

    Very soon we'll hopefully see more and better diesel cars in the U.S. - assuming the low sulfur mandate goes through. Most manufacturers that make diesel cars have not been pushing them in the US because our diesel fuel is crap; it's basically filtered and dyed heating fuel. Sept 2006 is the switchover date, there's a 20% phase-in lasts until 2010, only after that point (and only assuming Bush doesn't strike the bill for one of his buddies) can they be sure users won't be pumping 500ppm crap into the tank, so some manufacturers may hold off anyway.

    I started also in junior high on a TRS-80 Model I, level 1, 4K RAM. By the time I was done, it was expanded to Level II, 48K RAM, expansion chassis, 2x floppy drives, and RS-232 interface.

    Then I went beyond factory upgrades and using just logic chips added lowercase, inverse video (my own design) a 256K bank-switched RAM array (also my own design), a 360K 3.5" floppy, aftermarket NEWDOS-80, and added some circuitry to my dumb 300 baud modem to detect rings, dial, and allow it to pick up on its own. Then I wrote a pretty fully-featured BBS in BASIC with assembly-code helper functions (hand assembled, couldn't afford the assembler).

    I learned more stuff on that computer than it might even be POSSIBLE to learn on a new machine.

    Uh, the evidence will get obscured eventually by falling ejecta from impacts and stuff like that. It will likely take several hundred thousand to a few million years for that to happen, unless a sizable meteorite happens to hit right on a site.

    If you went up there right now you would almost certainly see very, very little degradation from when the footprints first went down. The only degradation would be from hot/cold cycles; it's possible that a few dozen/hundred grains of dust may have tumbled a few mm in the last 30 years due to this effect, but you'd have to look pretty closely to notice them.

    In fact, nothing really ever "graduates" from theory to law anymore. Stuff like the "law" of thermodynamics only got that because they "graduated" back in the 19th century (or maybe early 20th). These days we don't move anything to "law" status in science anymore, because everything is subject to further review, refinement, and possible debunking. Thermodynamics is really only a theory. It's an extremely well tested theory which has not had any evidence against it as of yet.

    Similarly, gravity is a theory. Every time you drop something heavy, it falls towards the most gravitationally influential nearby body. But there's always the chance that it won't. We do not fully understand anything at its most base level, really, therefore we can never say that any theory is always true, without exception.
