    I just heard about Turbo Codes recently, but from a different perspective. I think at the time, they developed these codes with rates so close to the Shannon limit, and no one believed it. Even then, I don't think they were aware of the theoretical basis for why they worked.

    Theory finally caught up with them more recently, from the framework of probabilistic networks. It turned out that if you have a Bayesian network with cycles, inference is difficult. But there is a method of belief propagation through message passing that can be used, and it turned out that this is exactly what these guys were doing. (The network itself would include a probabilistic model of noise and its effect on the messages from the sender to receiver.)

    Just an FYI for ya. I have an i8k relative (m40) and Mandrake (9.2 maybe?), and I had the same problem. However, you can actually fix the freezing problem by -- you guessed it -- recompiling the kernel.

    I don't have my laptop with me at the moment, but if you recompile the kernel with ACPI support disabled, you can plug and unplug the power cable to your heart's content without any lockups. I think removing support for it also required removing support for some IBM hotplug-related device. Let me know if you're interested and I can try to get a more specific list.

And if you're going to do it, I think it was awfully considerate of the poster to actually attempt to find ways of avoiding waking his roomies.

    Speaking for myself, I had a lot of homework in college.

I was the one who had stayed up late working on other homework the night before and had to stay up late the next night. My roommates all had different majors, though, all in the Engineering college, and we were all in the same boat. We were lucky to be in an apartment instead of a dorm room, that's for sure....

    Now developers have to start deciding whether or not to support higher resolutions, and if they do, what to sacrifice for the increase in calculations required at those higher resolutions.

    Yep. Which is why so few games actually support it, even new ones. Disappointing for those of us with HDTVs, but I can understand why so few developers go through the extra effort.

  11. Re:Not good idea. on Putting a 1.48GHz Tualatin CPU in an Xbox · · Score: 1

    I think you're correct; we're talking about different facets of the same problem.

    You're right -- it's easier to make a game (especially a good one) if you can target better hardware. And I'm exaggerating the complexities of development, especially concerning Windows of recent years. (I won't bother to include Linux varieties here, and Windows used to be worse than it is today.)

    But at the same time, my point is that it is easier to target fewer varieties of platforms -- sure, GC/PS2 are quite different, but the set is a small discrete space instead of a multidimensional almost-continuous one. And I think this is also a valid point.

    These two factors are not mutually exclusive, of course. So while it would be better for developers if the XBox had better hardware, in my opinion (because we're talking about predictions now) I don't think MS is going to officially allow upgrades like this, because I think the degree to which it makes life harder on developers will overwhelm the improvement in games for some people. Instead, they'll just make an XBox2. (I think this was my original point, at least! :)

    > Except, of course, that console developers get special Development Kit versions of the consoles, that are more powerful and capable of outputting higher resolutions.

    You're right, I glossed over that point. The development consoles need to be different, at least to handle debug code at close to a reasonable speed. The point still stands, though, that they have a single target, even if intermediate development is on a different platform. Even with three consoles, three targets is an easier thing to deal with than, say, 5 video cards speeds X 5 cpu speeds = 25 "speed" configurations.

    And even then, I've simplified the picture for PCs. Do we keep using DX8, or switch to DX9 now that it's out? Am I going to have an issue with ATI cards if I use pixel shaders? What glitz can I drop for a slow video card -- can the CPU take over some of that work? How about giving more work to the graphics card for a machine slow CPU? When the game is finished a year from now, what will be the base CPU speed we can allow? Not only do I have to worry about different speed configurations, I need to worry about different brands now, too!

    > Consoles have limited graphics capability (due to the extremely poor resolution of the standard television)

    True, but the limited resolution makes it easier to develop for, not harder. You may be able to do less with that resolution, but damnit, you know what that resolution is going to be and you don't have to worry about someone who wants to run at 2048x1440 and someone who wants to run at 640x480! Anyway, that is passing with HDTVs becoming more common. Many PS2/XBox games have support for progressive scan (e.g. 480p/720p).

    > very limited control set (even the Xbox's 4-axis 10 button controller pales in comparison to a mouse with a wheel, and a 102+ keyboard)

    That's true. However, there are many games -- entire genres -- where a mouse+keyboard doesn't make sense. Even so, that is simply another hardware restriction, which makes it easier to handle because there is less variety. You don't have to worry about supporting mouse+kbd and a joystick.

    > That's like saying Children's Books are better for Authors because children have a lower common denominator.

    Not sure I see the analogy. A book for a 2-year old and a book for a 6-year old bear absolutely no resemblance to one another, and trying to make one book (game) to appeal to (work on) all children (configurations) is virtually impossible.

  14. Re:Not good idea. on Putting a 1.48GHz Tualatin CPU in an Xbox · · Score: 4, Insightful

    I don't see this ever becoming common.

    First, developers would hate it. The beauty of consoles has always been that you know, as a developer, whether the game will work on everyone's system based on a single data point: whether it works in the exact same console you have sitting in your office. They don't want to have to worry about varying systems, and gamers don't want to have to worry about system specs.

    It is absolutely in the developers best interest to target the lowest common denominator (i.e. the base system) to have the widest market, even if there ever did get to be a significant percentage of people with upgrades in the wild.

    Not only that, it most certainly would void your warranty with MS, so I don't see the average customer ever being interested in it. How many console owners (including XBox owners) are less tech savvy than TiVo owners, and what percentage of TiVos have been upgraded? My guess is that the percent of modded TiVos is actually quite small, and the percentage of modded XBoxes (where the benefit of upgrading is even less apparent) will be even smaller.

    Here's the problem, though. They keep "offering" to stop sending me my paper bill. First question: why would I want to stop receiving it? It's an automatic reminder that it's due, it leaves me a way to pay by check if I change online banking companies, and it's a nice double-check that they're not screwing me.

    Continuing on: when I choose to stop receiving my paper bills (by a simple mouse click online), they won't allow me to go back to receiving them. I might be able to do so if I sent them a letter or something, but still.... Zero incentive to stop receiving the paper versions.

    Oh, sure it's painful! Extremely, tremendously painful. But mathematically it all works out.

    Take caustics, for instance, like a magnifying glass focusing a light source onto a small point on a surface. This is, and has been, done using raytracing.

    I've not actually implemented it, but I'm slightly familiar with the techniques. I imagine some intelligent sampling of incident rays, and maybe adaptive supersampling of these rays, would help a lot with the phenomenal costs.

    Photon maps are another solution, and (if I remember correctly), they implement forward ray tracing instead of the usual backward ones. Since you can then cast rays from the light source outward, this can be much, much cheaper.

    So, it can't work.

    Sure it can! Raytracing can absolutely model diffuse interreflections. However, while radiosity is an analytic (though approximated through a mesh) solution, raytracing typically uses a Monte Carlo sampling technique to achieve this. You can imagine how painfully slow this is, but it works just fine. (And it doesn't require meshing your objects beforehand, either.)

  20. Re:Physics engine compromised? on Gran Turismo 4 - Under The Hood, Driving The Prologue · · Score: 2, Informative

    Yeah, I'm a little torn as well. Take GT3's SSR11, for example. On those two 90-deg left-right corners, hitting a wall can be disastrous without any additional penalty. But on some of the longer, smoother corners (esp. the 180's), hitting the wall is almost guaranteed to make you go faster. So in one case there's no need to make life worse for you, and in the other, it's almost a necessity.

    To be fair, though, even in GT3 there was some concept of damage -- the tires. Wall-bouncing could force you to pit a lot more often than normal. I find it hard to criticise any decision Polyphony has made, simply because the results have been spectacular as a whole, but I think just a progressive damage model -- just a little bit of texture modification, a little loss in HP/handling, and keeping the extra tire wear, might have been a good addition, and a little less suspension-of-disbelief reducing.

    Out of curiosity, did you read the articles? They all talk about how you used to be able to bounce off opponents and walls in GT3 to better your time, and steps have been taken to alleviate it: while it's true that there is no collision damage, there are penalties for bumping too hard into either. I'll quote the GameInformer article.

    Also, for all of you out there who go used to driving like a madman and slamming into walls and other cars, you're about to get a heavy schooling. Major impacts with walls and other cars will penalize you and after the collision you'll be forced to drive at a top speed of 50 km/hour for 10 seconds. So, you may want to think twice before using some poor opponent as a spring on a tight corner.

    I submitted a similar question several months ago. You might want to check it out. It was more geared towards the PS2 and consoles, but there were a lot of good suggestions all over the board.

    On that note, by the way, consider a console. I never saw the point in them, as I've been playing computer games for twenty years. But then I got married, and (as you're discovering) the computer games are not nearly as social as the consoles. Consoles are geared towards multiple players, whereas there are very, very few games out there that utilize multiple players on a computer.

    On a highlight, there's always something like ePSXe and other console emulators. Get one set up and go rent some PS1 games! They're cheap to buy, now too, and almost any modern computer emulates the PS1 with cycles to spare. Get a couple of joysticks, (or buy PS1 pads and the converters -- they're out there but I have not tried them).

    There are also plenty of good old arcade games, so as another poster mentioned, MAME is a great idea. You can, of course, find ROMS online if you are so inclined. Golden Axe, Gauntlet, Double Dragon, Xenophobe. These may not be the best examples, but they're out there.

    So in short, I'm clueless for computer games per se. But for PS2/Xbox, my favorite is Baldur's Gate: Dark Alliance. It's simultaneous two player, cooperative, not split screen, contains plenty of shopping for new items (my wife loves that part -- seriously), and although it's not phenomenally long, it has pretty good replayability. The sequel comes out in the next couple months, too.
