From TFA:
It is a crime under state law (RSA 570-A:2) to use any sort of electronic device to eavesdrop or record conversations without the consent of everyone involved. It's a felony to record other people's conversations, and a misdemeanor to record one's own conversations without the other person's consent.
I think they meant, would you put regular (85 or 87 octane) gas into your Ferrari, instead of ponying up the extra 20 cents a gallon for premium (91 or 93 octane).
Higher octane gas resists burning better. In a high compression engine (or a turbo/supercharged engine), the extra pressure can make gas detonate instead of burn. That detonation is bad for the engine. Lower performance engines don't put as much stress on the gasoline, so they can burn lower-octane gasoline. Putting high-octane gas in your low-performance engine doesn't do anything except lighten your wallet.
Just tested on IE 6.0.2900... on XP, and the flaw does not work. I see the Secunia site, with a Secunia address bar. Even have active scripting turned on.
Actually, ABS does not shorten the braking distance. That's a common misconception.
What it does do is allow the wheels to keep turning, and not lock up. By keeping the wheels turning, the ABS system allows you to steer while braking hard.
Some basic traction theory (somewhat simplified since I'm at work:)).
Imagine that your tire has 100 units of traction to divide between braking, accelerating, and steering. You could, for instance, use 50 units to accelerate, and 50 to steer, or 33 units to brake, and 67 to steer. If you exceed 100 units, you exceed the available traction, and the tires slide.
Without ABS, jamming on the brakes usually results in the tires locking (most cars are designed so that they can at least lock the tires). You have exceeded the 100 units of traction, and so you continue on in the direction you are going. You cannot steer, as there are no spare units of traction to spend on steering. (Incidentally, since the coefficient of friction is low once you begin to slide, you are only using about 75% of the total possible braking available - this is the long way to stop).
With ABS, your car's computers rapidly pulse the brakes. You only use about 90 units of traction to brake, but critically, you have 10 units left with which to steer around the object in your way.
However, since you're only using 90 units of traction to brake, your braking distance is longer.
A truly skilled driver can get shorter braking distance without ABS by employing a technique called 'threshold braking.' This is pressing on the brake pedal just hard enough so that you are using 99-100 units of traction to brake - but absolutely no more. You are braking just at the threshold of locking up. This is how to produce the shortest braking distances.
Granted, for most people, jamming on the brakes in an ABS-enabled car will produce the shortest stopping distances, since they are not skilled enough to do threshold braking. But technically, ABS does not shorten braking distances. It's only valuable because you can steer and avoid a collision.
Only enthusiasts are likely to drive BMWs like the one described in the article. I seem to remember the 3-series had a reputation in those days for being a fun to drive but tricky to handle car. These randomly selected drivers are likely to not know how to drive such a car properly, since they have never owned one.
Was it the 3-series? I'm not familiar with 3-series prior to the E36, but Porsche 911's were known to be exceedingly tail happy.
A more interesting study (albiet a more boring one to conduct) would be to see how our accident rate has declined over the years with the gizmos coming into effect. Has anyone done something like that? Have accident rates declined thanks to the gizmos, or do they just offer a false sense of security?
Yes. I can't find the article now, but ABS/TCS combine to save about 7,000 lives a year in the US or so, IIRC (can't guarantee that number). ABS/TCS also work to enable all sorts of marvelous things such as rollover protection, etc. The electronics systems are, again IIRC, slightly more effective than airbags in saving your life.
Of course, accident reports don't seem to include "near accidents" that were prevented by ABS/TCS - who reports it to the police when they almost hit something, but didn't?
I think the article is flawed, though.
The BMW has skinny little tires (195 width), old suspension, etc. A much more fair test would've been to stick people in a representative car and let them do the runs first with all the safety systems turned on, and again with all the safety systems turned off. I don't know much about the other cars in the test, but the Impreza (from the photo, looked like an 04 or 05 STi) can disable the ABS by pulling a fuse under the hood. It doesn't have traction control, though. This way, you remove all the variables like suspension design, tires (hell, the Impreza's comes stock with summer tires; what if the BMW had rock-hard, worn out, cheap, all seasons?), and so on.
The strange thing is, I have a similar ICQ number to you (low one million's), and I have yet to receive a single one of these ICQ spam messages, and I don't have my user list set to only accept IM's from users on my list.
I'm not a racing game developer by any means, so I can't speak with authority on the subject. I've mainly gleaned info from occasional books (like the Development of GT4 coffeetable book) and some articles on how simulations are getting ever closer to real life.
Yes, I suppose you could buy the models from the companies; however, I don't think that this is done. For GT4, at least, the artists gathered up reference photos of all of the vehicles they included and modelled them by hand. Some of the cars in game were designed before computer design were available (for instance, the older Skylines developed back in the 70's, and the good ol' Subaru 360, developed way back in the 50's or 60's). Did they even have computer aided car modelling in the 90's? There's also the cost involved with getting the models from the car manufacturers, and then converting those models into a form suitable for the game. Not to mention - there's 650 different cars in GT4.
However, some games have different goals for representing the cars on screen. GT4 goes for a very antiseptic, photorealistic model of the car (though they still can't do wheels right...), while Forza has a more solid, slightly less realistic but more visually interesting representation. It might be easier, as an artist, to start from scratch rather than try to modify a hyperrealistic, million polygon model down into a stylized 3000 polygon model. (I've no clue, I'm not a modeller)
As far as the track data, I suppose that now that they've surveyed the tracks themselves, they have a pretty good baseline to use. Of course, the track configurations could change, and at the least they'll have to go out and photograph the tracks again to get updated signs and scenery...
But beyond the basic models, you have to create an intricate physics engine to make those models move around. It's far more than just horsepower and weight. I forget the exact number, but there's a few hundred variables tracked for each car that's plugged into the physics engine. You have to go out and measure these on the car, and convert these figures into numbers suitable for the physics engine. You have to diddle with the physics engine so that it can handle crunching those numbers (for a grid of multiple cars, too) at a suitable refresh rate (60 times per second for Gt4, 240 for Forza).
Then design an AI that can realistically 'drive' instead of following the same line over and over and over again.. Make sure that isn't too robotic, but make sure it is competitive too, and oh yeah, make sure the processor can handle that load..
For Forza Motorspots, you have to build in a damage engine, too - how do the cars get damaged if you slam into a wall (maybe the manufacturer's data would be helpful here!), and how does that impact the physics of the car?
I think both designing an RPG or a racing game is a difficult task. Yeah, there are shortcuts (for both; the RPG designer can say, "Ah, just slap in the gnoll model from RPGame1, he's a level 1 bad guy, it doesn't matter"), but I think that if the designer is tempted to take those shortcuts, it'll show up in the end. It depends on if you're trying to develop a class-leader like GT4 or Forza or Final Fantasy *, or if you're aiming for an arcade racer or Diablo-clone.
I'm curious to see what the average development times for a good RPG and a good driving game are.
I like the Gran Turismo series, and I like to write. Writing takes time. However, GT4 has 700+ car models. It's gotta take someone some time to make those. Then you have to collect the performance data for each vehicle (and I've seen photos of the GT4 team test-driving the actual cars with data-gathering gear attached all over). It's gotta take some time to simply find the real-life cars you want to include in your game.
Then you have to generate those static tracks. The real-life tracks featured in GT4 (Laguna Seca, Nurburgring, etc) were all meticulously surveyed - the virtual versions are supposed to be within 15mm of their real-life counterparts. That's gotta take some time, not only to collect the data, but to convert it into a format that can be used to render the track on game.
I'd say that both RPG's and driving simulators take a ton of time to do, but perhaps in different areas. It does take a long time to write out a good back story, and it takes a lot of time to gather up all of the data that you need to make a good driving game (arcade racers, I'm sure, take a lot less time).
KK has been used for ages. I remember using it when I was playing my friends Doom on 14.4 modems, and I'm sure we weren't the first. It's just easier to type kk rather than ok.
I think this snippet from the article is more relevant:
After we colored the case, we reassembled it and set out to test the unit the best we could without actual CPU/GPU die temps. The best way we knew to get temperatures from the system was to take readings from the back of the motherboard, directly under the CPU and GPU while the system was running. We used a temperature probe taped to the back of the motherboard and these are the results:
With stock Xbox 360 cooling, after an hour of Quake 4, the back of the motherboard temperature was 150.8F ( 66C ).
With the water cooled Xbox 360, after an hour of Quake 4, the back of the motherboard was a full 50F cooler than stock cooling at 101F ( 38.4C ).
It seems to me that a 50 degree reduction in temperature is, one way or another, useful.
Newspapers take advertising to support themselves. There is a clear editorial wall between Journalists and AdvertisingSales in a newspaper. Why would it have to be any different at Wikipedia?
That is true, but advertisers have been known to pull money away from newspapers that don't print their version of the truth. For instance, General Motors pulled all of their advertising from LA Times after they printed an article criticizing the G6 and GM's business practices.
How good is the EFS in XP? I recall that in W2K, it wasn't exactly a fool-proof way to keep people from accessing your files (especially on a laptop, where people could have physical access to the machine), due to the way the RA was set up...
PGP had a feature that allowed you to create encrypted volumes. I know in PGP 8.0, it wasn't part of the 'free' version, but it could be unlocked when you registered.
Are there any cars that do that (automatically start up based on proximity of a key, rather than requiring someone to push a button or insert the key into a slot) currently? I'm curious.
It seems like it would be a safety hazard to have a car automatically start up when you walked near it. It would suck to be a mechanic with your hands reaching into the engine when the owner walks up, keycard in his pocket.
For the electronics reviews, perhaps they assume a less experienced user? For reading things like data transfer times in computer mags, there's a fair bit of expertise involved in getting optimal transfer rates depending on the CPU's used, the hard drives used, network type, etc. Perhaps CR is just giving values for running the machines right out of the box.
You illustrated my point!
CR isn't a magazine that uses specialists to review products. The car guy covered in motor oil is interested in wringing out every last tenth in the 1/4 mile. The computer guy covered in Cheetos dust is interested in wringing out every last frame per second in the latest game. CR doesn't cater to them in their interests. CR caters to the car guy when he needs a PDA to do some fine tuning on his ECU, and to the computer guy when he needs a new car to carry his carcass to the 7/11 to get more Cheetos - in other words, they know something about everything, and not everything about something.
Their user reports are sort of silly too.
As the OS X example illustrates and my Impreza body integrity rating illustrates, what users experience don't always make sense. Why would the 05 Impreza rust more than the 04 Impreza, when there was no change to the bodies of the cars? Why would so many OS X users report having a virus when there aren't any (are there? I'm not a Mac guy; I need to right click;)).
Amusingly, while they seem to have decent data for reliability, many car enthusiasts scoff at Consumer Report's car tests.
For instance, many of their acceleration reports are much, much slower than what other magazines report. For my Subaru Impreza WRX STi, they achieved a 0-60 time nearly half a second slower than what Road and Track, Car and Driver, etc, report (half a second is quite a long time for 0-60 times). For the 2002 WRX, their 0-60 time is eight tenths of a second slower than what C&D reports (that's huge!) They tested the Mitsubishi Lancer Evo and came up with a 0-60 time of 5.3 seconds; Car and Driver hit 5.4 for the WRX (and the EVO has 50+ more HP than the WRX!). CR similarily lags behind in measurements of other performance stats (braking, handling, etc).
Another thing I find funny about the Impreza ratings is how much the data varies. For instance, in 2004, "Body Integrity" was rated as "Better than Average." In 2005, the same category was rated "Unsatisfactory." There was no change in the body between the 2004/2005 Imprezas. I can't see what would change their rating so drastically.
I realize that CR is hardly a car enthusiast magazine, though, so it's forgivable that they aren't the world's best drivers. But unless you view your car as an appliance, it's generally better to look elsewhere for car reviews, in my humble opinion.
I guess my point is that to pick a review site, you have to take into consideration the reviewer's point of view. For someone who doesn't have a clue about electronics, CR is probably great. For those of us who love computers, it's hopeless.
On one forum that I hang out on, someone a while ago did a Google search for "black people." Sure enough, the Ebay ad came up - "Buy, sell, and trade black people on ebay!"
I can't recall if the ad would occur for white/red/yellow/etc people.
Someone e-mailed Google and got a generic, "Thanks for reporting this, we take you seriously" type e-mail in reponse. They wrote back and said, "No, seriously, try it." A real person then actually wrote back and fixed the problem.
I can't believe that Kali is doing something political that I agree with! First CARB, then their ridiculous firearm laws.... This is one case that I hope they win.
