  1. Re:That's some impressive bandwidth there on Sony PC/DVR Incorporates 7 Tuners & 1TB HD · · Score: 1

    My guess is that they'll use something comparable to a 3ware hardware (P/S)ATA raid chipset, with four to six drives in a raid 0 arrangement: they need as much as speed as possible on those disks, so a JBOD arrangement is only practical if they're trying to save money. Since PVRs generally give little or no consideration to long-term stability and viability of data, raid 0 (the fastest but most failure-prone) makes more sense than raid 5 (much more complex and a bit slower), and obviously raid 1 is straight out.

    With a good hardware controller, raid 0 can come extremely close to the arithmetically combined performance numbers of the disks, up to the hardware-imposed speed limit of the bus. A 3ware controller sitting on any modern fast bus (think PCI-X or PCI express) should be able to handle the combined data coming from seven 480p signals without too much trouble. Assuming television frame rate of 30fps, at 480p resolution (480x720) with a 24-bit color depth, you get a total count of 248Mbps per stream uncompressed. Taking this times the 7 controllers, you get a maximum uncompressed bit rate of 1742Mbps.

    My WD 1600JD sustains 35MB/s, so assume that six of these could sustain 200MB/s (just under 6x35) or 1600Mbps, which could be easily handled by 66/64 PCI (limit of 4224 Mbps), never mind anything faster. With higher performance disks, this job could still be done on 133MHz PCI-X (limit of 8448 Mbps) since the maximum possible combined bandwidth of 6 ATA-133 disks is 798MB/s or 6384Mbps.

    So basically, reasonably high-quality (EDTV) resolution should be completely doable using standard components with 7 tuners. It *would* require everything to be well designed, and it would require a good balance on the PCI bus (probably a dedicated bus just for the disk controllers), but it should be doable.

    As an historian, I would like to point out that Ferdinand and Isabella of Spain knew nothing of navigation, and in fact weren't even particularly interested in sailing per se, and yet they are inseparably linked with the final European discovery of the New World in 1492.

    Why, you ask? Because they bankrolled it and told everybody so. Of course they were shooting for a valuable spice trade and missed, but the point is that Columbus, an Italian with few resources, was not bankrolled out of altruism or interest in discovery, navigation or research, but out of a desire by Spanish royals to be rich and to stand out among European royalty as the greatest.

    Don't jump to conclusions about what I'd be interested in. I see your point and I respect that. To be honest, the most cutting-edge games I ever play are Quake 3 and MotoRacer 2, and my favorite modern game is Civ 3. I still play on my old Nintendo (I've spent more money maintaining it than on all post-1998 games I've ever bought), and if I still had my Vic-20 I'd play Avenger, Speed Ski and the like.

    I was just doing the "When I was a kid" kind of thing - since the original poster was making the Qbasic environment of 1998 sound archaic, I was pointing out that it's downright feature-rich compared to what we used to have. It's kind of obnoxious and silly, a bit like old people who talk about how they used to get a nickel a week and were satisfied, ignoring the fact that there's a thing called inflation (or in this case, Moore's Law).

    More power to you, I'm sure everything you're saying is true. There's nothing wrong with Qbasic if that's your gig. I respect that. If I were to start writing games in BASIC again, I'd personally do it on the old platforms that were designed for it; but if you like QBasic, great.

    I hate the massive commercialization of our lives, and the thing I really liked about the state of personal computing in the late 70s and early 80s was that it was so grassroots, where kids and parents sat at home together, with or without any inherent knowledge of computers, typing in lines of basic into their computers to get a game. They were directly involved with the creative experience, even if they didn't really understand what they were putting in. People could modify games easily, tailoring them for better or worse to their tastes.

    This movement and this grassroots connection to computers largely dried up as the brands slowly failed and the wide diversity of simple machines disappeared. Qbasic is certainly the closest thing we have to that now and it's nice to see continued work in that direction. There I go reminiscing again...

    I'd like to think that I had a small hand in starting that fad, with a little Qbasic RPG demo I released in 1997.

    Perhaps I'm wrong, but I don't think any fad involving basic could have been started as late as 1997. Qbasic, though not quite a footnote on basic, certainly is a late entry into the world of basic language variants, and by 1997 even Qbasic was pretty unbelievably old. Anybody worried about fitting basic into an ungodly huge 450KB (!!!) is pretty wasteful with space...

    I'm somewhat of a latecomer to basic myself: I taught myself basic at home on a Commodore VIC-20 and at school on a PET, until the school replaced them with Apple ][e machines, and then when I was in 8th grade, just-released Apple ][gs machines.

    You don't know memory limits until you discover that a Commodore VIC-20 had 3KB of user-available RAM!!! Even simple games like speedski barely fit. And of course the 22-column screen made typing programs a chore. The C64 with the 80-column card was a prize for sure - it had over 50K available to the user, and an 80-column display with 8 colors.

    One thing I always liked about basic though, was that all the different variants (Timex/sinclair, Commodore, Apple, HP, etc), despite a lack of any desire to follow any inherent standards, were close enough that with a little acquaintance and/or any of the monthly magazines full of programs and hints, it was possible to write a program for any of them. And the laborious man-hours of manually copying code from a magazine into a computer meant that I knew how to properly type by my seventh birthday.

    Anyway, you can keep your Qbasic games of 1997, by which time there were all sorts of really *good* games being developed for real hardware using real languages. If I'm going to play basic games, I'll take speed ski, snake race, avenger, and the like.

    It's actually more rational than that. The station's interior is filled mostly with oxygen, which I'm sure you know facilitates fires even in relatively low quantities such as we have here on Earth. When circuit breakers flip, they often emit sparks (and that blue-electric smoke and smell). If the circuit breakers were inside the nearly 100% oxygen environment, there would be a relatively high chance that the whole thing would go up in a beautiful blaze of glory when the breakers flip and/or die.

    Also, even electronically-controlled circuit breakers are fairly error-prone, likely not to flip until a serious over-current condition exists. They're nothing like the crap we have in our homes (a residential-grade 15-amp 120V breaker can often take over 30 continuous amps before it flips, and in short bursts even a load of 300 amps might not flip it), but they're still error-prone. Hence, it's a good idea not to build the station as a ticking time bomb by essentially putting a time-delay fuse inside the gaseous environment.

    If your model and my model differ, then we disagree about reality, but we are probably not correct (either of us).

    I agree with you completely, except that the very point of postmodernist approaches is that there is no such thing as correct or incorrect; there is observation and perception, which are sometimes shared and sometimes different. Science does NOT define reality; it simply provides a set of observations that are repeatable by anyone who follows the correct procedures and uses the right tools. These reproducible "facts" are of course of extreme use to our society, and I don't think postmodernists would claim that science is anything less than a boon to our society and our understanding of our universe. However, they would argue that there is no such thing as "correct" and "incorrect" because our understandings of such are merely anchored within the model we hold of the world around us.

    So DJerman, I agree completely with you, and I think you agree completely with postmodernist critique as it is understood in the academy. The "Individual creates reality" kinds of statements are made by people who don't understand the inherent critique made by postmodernism.

    Remember, postmodernism isn't really a philosophy per-se because even its strongest proponents (Michel Foucault should immediately come to mind) realized that it was not very useful for creating new interpretations of human nature. Rather, it is a tool for criticism and critique, a way of addressing the shortcomings of modernist notions of progress and the human condition. It was often said during Foucault's life that his own works of history were not really postmodernist, because in order to make a strong historical argument he had to betray many of the tenets of the postmodernist "we can't really know anything" dilemma.

    Of course, I've been immersed in postmodernism for so many years that I'm not even sure I exist anymore. I don't call myself a postmodernist - I think the term has no meaning since postmodernism is not really an ideology (although it is taken to be one by people who have a little knowledge of it and think it sounds good); however, I think the postmodernist critique is an important one and very relevant for addressing many of the shortcomings of our perception of our condition.

    All carnivores eat other animals; very few eat their own kind. It *IS* of course a *very* bad idea for humans to eat monkeys and other primates because we are so closely related to them and diseases and other problems can spread rapidly among such species of the same family. So, unless you think eating monkey brains is a good idea, your point is not correct.

    Furthermore, in nature as a general rule flora do not eat anything; herbivore fauna eat flora and no other fauna; and carnivore fauna eat herbivore fauna and nothing else. With few exceptions, no animal eats carnivore fauna for nutrition. This is the primary reason why as a general rule nothing eats cats, dogs, or humans (we are the only carnivores/omnivores in the primate family, I believe).

    Cannibalism, and similarly the consumption of other primates, is a bad idea for disease reasons; from a nutrition standpoint (the *primary* reason an animal eats, unless it's wealthy and living in a developed country) there's really nothing wrong with eating any animal, even homo sapiens, though of course carnivore meat is both less nutritious and more disease-prone than herbivore meat.

    So, human flesh is essentially just the meat with the highest level of evolutionary risk for humans to eat: like primate meat (which we generally do not eat) it carries genetic diseases that can afflict us; and like cat or dog meat (which we also *generally* don't eat - I know there are exceptions) it is not very nutritious *and* is much more disease-ridden than herbivore meat. So, if you claim that human meat is the *only* meat that's off limits, and you think the *only* reason we don't eat humans is the social taboo against such behavior, then of course you're right - my argument doesn't hold up. However, if you recognize the vast array of meats that are unsafe for human consumption and the great combination of reasons why eating human flesh is dangerous, leaving behind the social taboo, then you'll see that in fact that genetic engineering and meat consumption, though closely linked in many ways, do not share the simplistic and uninformed relationship you hope to draw in your post.

    If *all* animals were safe for humans to eat *except* humans, then you might have a point; but of course there are very good genetic and evolutionary reasons for what we do and do not eat. The next time you're eating a black leopard, give me a call.

The screen was considered "great" at that time as most of the laptops I was looking at had 9.1" straight passive screens with 8-bit color. Many still had passive greyscale screens in 1994 for obvious reasons - if you only have 512 KB of video RAM (standard on low-end, ie sub-$4000 laptops) and are limited to 8-bit pixel depth, you can get a lot more shade resolution with greyscale.

Most video games, in full-screen mode, scale to whatever resolution you're at so the only factor is the number of inches, not the resolution. And remember that a 640x480 display will look about the same on a nine-inch screen (in terms of graininess) as a 1280x1024 display on an 18 inch screen. So the graininess will be fine, which leaves as the only question whether you're sitting close enough not to mind the small size. Remember that portable DVD players generally have 7" screens and the good ones display a beautifully rich cinematic picture.
