    I can see why you think that way, but it's certainly not ever required to be in an HOA. Back to back terraces aren't exactly rare in the UK, and if you own one of them, you share the walls of your house with three neighbours. Over here HOAs aren't exactly common.

  5. Re:You keep using this word 'Parallel'... on To Grid Or Not To Grid? · · Score: 1

    ;) What I mean is, take advantage of any parallism possible due to the nature of the task without recoding the application. An individual job won't be finished any quicker that way, but all jobs will be finished sooner. Parallel programming is different, since this involves multiple threads of processes communicatating either through shared memory or with some form of message passing.

  7. Grid != Parallel on To Grid Or Not To Grid? · · Score: 2, Informative

    I can't help but feel that people are missing the point of grid computing. Grid is not HPC. It's not super computers. You can build grids using HPC, but they don't have to go hand in hand. As such, all this talk about parallel whatnot is actually missing the point. I assume there exists code. I assume the code is serial, since most is. I also assume that there are many of these jobs, rather than one job that currently takes a day and a half. Typically there's no need to start getting exotic with MPI/OpenMP or whatever. Simply submit more serial jobs to do what needs to be done. Look at it from a batch scheduling point of view, and see what can be done. If you want to parallelise it as well feel free.

    Grid within a company typically just means decent remote access to a shared cluster. A web service that submits jobs to sun grid engine (which has nothing to do with 'grid' btw) would probably fill in all the buzzword bingo requirements of a grid project without being anything of the sort. For sadists look into OMII and GT4, but don't feel compelled...

    You wouldn't get that much of a refresh rate drop. The GPS will use no graphics power, the DVD is pretty light going, leaving most of the power for the game. I suspect you'd still pretty much hit the 60Hz refresh a lot of LCD screens are limited to anyway.

    There's no bleed. I've seen the 2 view versions, and they're fine. Thinking about the technology there's no reason to think there would be bleed (assuming you're sat in the correct place), since you've effectively got an LCD grill which is presumably capable of being just as dark as the LCD's used to make black normally. In fact, since they're not expected to be anything other than black or white, they might actually be better at it.

  12. Re:hmmm? on Early Testers Say Vista RC1 Not Ready · · Score: 1

    I agree it's very chipset specific, but then it sort of is under windows too. The Intel networking drivers seem to be the best under windows and linux (ipw2200 is what I use). WPA "just works" with wpa_supplicant and NetworkManager, so I can use it in a very similar manner to under windows. I just click-select the network I want to use and type in a key and it works, and remembers all the passphrases too. But then a ralink based card under windows causes a 90 second pause after login. Bad drivers suck, but they're not limited to windows.

  14. Re:good for cameras? on Ultra Wideband Hub Coming in October · · Score: 1

    Do people really bother that much about battery life? I've got a 350D with a battery grip, and that gives me maybe 1000 shots. If it matters that much buy another battery clip, and you can change both batteries with another clip in two seconds. Wi-fi really doesn't use that much battery power either, certainly not enough to bother my PDA.

    I'm not saying you're not wrong that this is good but it still means attaching a battery powered wireless doobrie to my camera, which if it's generic is going to stick out annoyingly surely? Note the canon add on costs about £700 to bring wireless to the better end of the range.

    I think this is more useful for providing USB ports for keyboard/mouse/memory sticks to our board room table, as currently the only option is a USB->CAT5 range extender.

  17. Re:didn't know processors have memory on NASA Scientists Simulate Black Hole Collision · · Score: 3, Informative

    I think you need to relax your terminology a little. On an Altix box you have what used to be called C-Bricks. Basically a unit that contains processors and RAM. Those all link together over NUMAFlex (with appropriate routers) to form your large shared memory machine. But the RAM is still localised (as it's a NUMA architecture). So 'main memory' should be considered as 'owned' by a processor (or processors). If you'd made an OpenMOSIX cluster to match you'd refer to it as a machine's memory, but since all these C-Bricks form a single machine whole, you can't do that.

    Having just been to Beijing and Moscow, I'd say it certainly feels like China has deregulated a lot more than Russia. Talking to a Chinese friend from home I learnt that economic reform has been going on for a lot longer in China than Russia, despite Russia 'turning away' from Communism. But in the same breath I note that a local commented that in China it's a communist country for the ruling elite, but not the general population. But that's the joy of implementation vs specification.

    I didn't think you meant that ;) But you're right, cars here are generally less powerful, but much lighter and with much better suspension. Things like the Prius really haven't made much of an impact over here, because they're not really any more efficient. It's a strange woman that refuses to get in a Passat. The Skoda I can understand, although much is in the name. The plastics are pretty rubbishy still, but then if they weren't I suspect VW would suffer.

    Absolutely. I wanted to try and pick on the most popular cars though, as I couldn't think of an entirely fair way to pick what people drive otherwise. Certainly choosing an oil-burner is fair game though, as diesel is very popular over here. We don't all drive Jaguars in the UK ;) In fact I'm even more efficient than either of those; I don't drive. I thought about it once.

    In general, switching to cars with better MPG means cars with less size, power, acceleration, style and safety.

    I don't buy that in the slightest. Yes european cars are generally smaller than US cars, and have less power, but I don't buy the rest. Top selling US car is still a Ford F150? Take the figures off pricegrabber (since ford are shy of 0-60 times) and you get a 5.4L V8 with 300bhp, a 0-60 of 9.12 and 15MPG combined or 20MPG extra-urban.

    Top selling UK car? Ford Focus. Let's be really mean and pick the biggest Estate version, and not go silly with the spec or we'd beat you too much on performance. 1.8L 4 cylinder with 145bhp, a 0-62 of 9.4 and 28MPG combined or 52 extra-urban

    I'll ignore safety, but that's really letting you off. And point those at a corner and you know which you'd rather be in, that's not even a challenge.
