  2. Re:The PS3 is starting to stock some shelves on Grey Markets Compared - PS3 vs. Wii · · Score: 1

    I happened across a Wii at a Target last week, but I've since visited a lot of Target, Wal-Mart, Best Buy, and Toys R Us stores looking for Wii accessories and another unit for a friend (his wife finally found one yesterday after visiting about 15 or 20 stores).

    I've seen a number of PS3s. I wouldn't say they're plentiful, but (for example) one evening at the Fayetteville, GA Target, Wal-Mart, TRU, and Best Buy, I saw 6 of the 60 GB units sitting on the shelves. So it appears that the demand for PS3s is close to being met (at least in the Atlanta area), but the demand for Wiis still exceeds the supply.

    (I would be curious to know how many of each console have been sold to this point.)

    >>My point is that, in a condtion of bumper to bumper traffic, once two lanes of equal speed merge into one, the traffic speed in the remaining lane has no alternative but to double.

    I guess I kind of see what you're saying - if you truly had two lanes of truly bumper to bumper traffic merging into one, the speed of the one lane would have to double to create enough space for twice the cars in half the space. That's not the case here, though.

    I described a construction zone, with advance signage ("Road construction 2 miles/1 mile/1000 feet" etc.). It wasn't two lanes of bumper to bumper traffic - once we hit the backup, it was pretty much one lane of bumper to bumper traffic, and a number of "aggressive drivers" who figured they could get ahead by zipping farther down the line before merging. In this case, the drivers in the through lane (the lane that isn't closed) keep having to stop or slow down to let people merge (or because people are cutting them off). Once that "turbulence" goes away, the traffic speeds up, and the truckers forced that to happen farther upstream than it would have without their intervention. We had a brief period of increased delay while all the cars merged, and then a nice period of uninterrupted free flow.

    Yes, I'm sure I'm a traffic engineer. I'm also sure that I have no idea what you're talking about, and I'm not sure that you do, either.

    It's simple: once all the merging was done, all the cars stopped having to slow down or stop to let people merge, and were able to get on with simply driving in a straight line through the construction site. The truckers forced the merging to happen farther upstream, so we were able to reach the nice steady state flow speed for a mile or two before the construction site, rather than at the actual bottleneck (past which there was no merging because there was physically only one lane).

    It's neither physics nor psychology, it's traffic flow theory.

    Hah! Amazing - I just posted a similar observation (before reading your post) somewhere up above.

    I have a couple of friends that drive BMWs, and they're fine people (and I'm sure BMWs are fine cars). But I've had YEARS of driving experience, observing the behavior of other people, and for some reason, you DO see a lot more asshole driver behavior from BMW drivers. I don't know why that is, but it happens too much to be coincidence. It's not sports car drivers, or Mercedes (similarly priced German car) drivers, it's BMW drivers specifically (and all models - Z3s, sedans, SUVs...).

    I'm a traffic engineer that drives in Atlanta every day. I know ALL about idiot drivers and the bastard behaviors that they drive you to. My biggest pet peeve is what you describe, people who fly up to the front of the queue and attempt to cut in - I'll do everything in my power to prevent those bastards from getting into the line. On the other hand, if somebody turns on their signal to merge ahead of the LAST POSSIBLE INCH OF ROAD, I'll happily slow down and let them in.

    Once, driving on I-85 from South Carolina through rural north Georgia, I saw a very striking illustration of how merging SHOULD work. It's a 2-lane interstate, and bridge construction had one lane shut down, and traffic backed up for several miles. Traffic was CRAWLING, in large part due to bastards (an unusually high percentage of BMW drivers, for whatever reason...) running up to the front of the queue. Then something interesting happened - the truckers got organized.

    A bunch of truckers pulled into the center of the two lanes, blocking traffic from passing them in either lane. That forced the traffic in the "cells" between trucks to go ahead and merge into a single lane - there was no point staying in two lanes anymore, because you couldn't pass the truck to fly up to the front. What was awesome was that as soon as all the merging was done, traffic sped up a good 10 to 15 MPH. Once everybody got into a single lane, the "turbulence in the flow" that was causing things to really crawl was gone, and everybody got through the bottleneck a lot faster, rather than just the selfish bastards that had to cut into the front of the line.

    When/if I get a PS3, it'll be my first HD source, and I'd probably start considering getting an HDTV a little more seriously. I don't have digital cable or satellite and don't really want it, and I can't be bothered to hook up an antenna for over-the-air HDTV, so the benefit of an HDTV is fairly limited for me right now.

    I've spent some time watching my friend's SXRD. He has Dish Network, and HD stuff looks good. DVD looks good. But standard TV ranges from OK to nearly unwatchably bad, when you combine the compression of the satellite feed with the upconversion to 1080p for display. That also dampened my enthusiasm for HDTV.

    I wouldn't go so far as to say that HD-DVD and Blu-Ray are DOA, but they definitely have some things to overcome. The benefits of DVD over VHS were fairly obvious and easy to take advantage of. The benefits of the new formats (which still look, media-wise, just like a DVD) are a little more esoteric (and mostly of interest to "videophiles"), and require a lot more hardware (expensive player, fancy new TV - and the world of HDTV resolutions and display technologies is still incomprehensible to 75% of the world) to take advantage of.

I did upgrade to 2 GB of RAM (aftermarket), though, so maybe that helps (since the integrated video shares memory).

    Also haven't had a problem with the glossy screen. I like the look of it, and I've used it outside in the sun, in the office with overhead lighting, at home with lamps, in bed, on the sofa, etc. without any serious glare issues.

    It's a little strong to say that the MacBook is a poor substitute for a MacBook Pro. I weighed the pros and cons of both recently, when I was looking for a decent machine for personal travel purposes, and the only thing that I was really concerned about was the integrated video on the MacBook (which hasn't been a noticable problem at all).

    If you want a desktop replacement, the Pro is obviously the way to go, but I'm not sure it makes a lot of sense to try to squeeze a desktop replacement into a 12" chassis. For the size and the money, the MacBook's a fine machine.

You get to the exit, press the button, and the floor drops down leaving you face to face with an Imp. Scared the crap out of me, because I was conditioned to assume that I was done with the level when I pushed the button, to the extent that I actually flung myself away from the desk in my rolling chair and had to scramble for traction to pull myself back to the keyboard and kill the Imp.

    I don't know that I was SCARED per se, but I was greatly creeped out by those little spider things that always jumped out of urns and stuff in Unreal. I hated those things. I remember one level where several of them jumped out at me, and I kind of ran backwards in a panic (in the game) firing wildly at them.

    Doom 3 never really scared me with the monsters jumping out at me, but there was one level late in the game where you were in a hall and there was some sort of female (or child) whispering indistinctly, and a set of bloody footprints began to appear down the hall. I was playing late at night at home by myself, and that creeped me out so bad that I had to quit playing for the evening.

We assured him that we were engineering students (my scale and scientific calculator seemed to be sufficient proof) and he just told us to finish up and move along.
