    There's no reason to simulate weather. Any significantly large space will have climates you can't finely control. With that said, there are few reasons to have real trees. Most nutrient rich foods (like spinach and beans) don't take much space to grow. Lakes, fields and trees may not have much value until tourism plays a role in colonization. You don't need a Biosphere 2 -- if carbon can be treated as a closed system, the plants you eat should soak up what you exhale. As long as you have plants on hand for every person introduced instead of supplying additional MREs or the like, the system should balance out. If colonists lose weight, one may need to sequester some carbon to even things out, but that's a different discussion.

You don't have to read much about the Ares program to realize there's more than a little dissent among the ranks about some of the design decisions here. You also seem to equate replacing Griffin, who silences opposition as best as he can through demotions instead of communal discourse, with disbanding the entire space program. Seriously, who makes that kind of absolute?

    If we can find a replacement who can listen to the educated engineers who think the program is too risky or that it can be done more efficiently, or if we can efficiently accelerate the whole program, why not do it?

    That said, there's a reason you don't see much GaAS integrated circuits, even though GaAs has been around for decades, and has much higher carrier mobility (and therefore top speeds) than silicon: it's hard to devise a good IC technology for GaAs.

    We used to say the same thing about SiGe, but that's starting to make its way into CMOS technologies. Standard 100% bulk Si is hitting the wall of what's possible. Even if geometries are 10-20% bigger, but provide better switching speeds, on currents or lower off currents, we're going to have to keep working in order to improve. Further improvements, like our accomplishments to date, will not be easy. I don't know what advantages GaAs or graphene will have to them once their issues are worked out (you can bet several advantages will have to be compromised to ramp production), but I know that GaAs has higher defect rates, so that's one thing that's going to have to improve before we see it changing ICs as we know them.

    There's no way you could describe today's technology that we take for granted to an expert 20 years ago and have them believe you. Copper and SOI before 2000 (in 1997, some experts predicted each were 10+ years away, to say nothing of merging them)? A return to metal gates? Vertical FETs?

Unfortunately, they both rely on people in your region being interested in the same torrents you are, while P4P additionally benefits from an iTracker, an ISP provided tracker that's topology aware (they did some work to prioritize based on ping latency, using that as a distance estimate, but I don't know if it's a fallback mechanism). Due to the iTracker infrastructure and possibly conflicting supporters, there are some privacy concerns.

  8. Re:Well Duh on Bittorrent To Cause Internet Meltdown · · Score: 1

    BitTorrent is going to find out, very soon, that it shouldn't try to be a bully; it's making other customers vote with their wallets, and if you force the point, there are actually a ton of ways to stop this cold (which unfortunately hurt the rest of us too, like caps).

    BitTorrent is responding to the bully. ISPs have a choice here, acknowledge customer behavior and find a way to work with it, or fight it. They almost managed to work with it with the P4P initiatives, but they involved media companies who will undoubtedly find the centralized and friendly owned tracker logs easier to get. If ISPs went with common carrier arguments and found a way to publish their network topologies and got trackers to behave similarly to P4P, then everyone would benefit. P4P isn't about denying people access to off-ISP data, it's about preferentially treating free pipes. If you need to upload and the free pipe isn't available, you still get access -- and those off big company owned ISPs still get their data.

    BitTorrent is designed to maximize use of everyone's available bandwidth. Azureus can give me better transfer speeds than any single HTTP or FTP server I've found. If the ISPs want to continue to ratchet up this game, then maybe the 'net truly is in for a meltdown. If the ISPs backed off just a hair, there wouldn't be a reason to investigate these harder to block methods and we could all find solutions that work for everyone (except maybe copyright holders) because siding with the copyright holders will only harm consumers and ISPs.

    In a court of law, reading the pirated version may be interpreted as a violation of copyright. Your defense attorney would have to discuss intent, and the degree of your "good faith effort".

    Why are ebooks so much better than paper books? Did you look around for the paper book new, did you look for it locally used, did you only look at Amazon, did you write to the author, etc. This can easily become a very gray area, although my understanding of "fair use" interpretations of copyright would suggest that if you bought the dead tree version, scanned it, then read the scan, that would be fine. I personally don't believe substituting someone else's scan (or transcribing) would materially affect the ethical question.

    Of course, in my opinion, discussing morality and legality are two different questions, but they must both be asked at the same time often. For example, what if you bought it from a local seller, scanned it, then resold it in the same condition? The book's value does not change, you don't net any positive or negative money, so why bother buying and selling the book anyway?

Side by side, I can tell the difference, but most content on television is not actually improved by increased bitrates or resolutions.

    Look, I don't think overclocking in liquid nitrogen is cause for a slam dunk conclusion that AMD is now competitive with Intel, but stating that it's not impressive and not an indication of the performance of the processor indicates a complete lack of understanding of electrical design.

    This wouldn't have worked, for example, with the original PPC 7400 (G4) past 500MHz. As it turned out, there was a hard stop getting past that. Finding FMax (maximum frequency) independent of reliability and power concerns highlights design weaknesses. If they can overclock by 50% with adequate cooling, one can conclude they don't have any early or late mode problems preventing higher frequencies, and that metal isn't the limiting factor. In fact, they can easily conclude that the electrical design is sound and that their limit will be what they can qualify from a reliability perspective.

    I'm certain everybody has their own hard drive death story, but here's mine.

    I had a summer internship for an IT department at a large engineering firm. I wasn't afraid of Unix, so I was blessed working with that department (1995?). There were these HP 735 (PA-RISC) systems that had recalled hard drives. We were given serial numbers of the drives recalled, but had no way to map the recalled serial numbers to the workstations themselves. The team decided there was no way to realistically handle the recall, so we'd just swap out drives as they failed. Everything was stored on the network and there were only about 4 config files that were unique to each box, so the inconvenience was minimal. After about three failures, I learned the sound they made. Each day I'd walk through a building or a floor, track down and record the boxes that made the sound, take them down at lunch to verify the serial number, then schedule a swapout with the user. "Listening to your hard drive, I have reason to believe it's been recalled and will fail soon" was a pretty good way to get flexibility from a user.

    One day, I'd forgotten my list of recalled serial numbers so I called the admin who was overseeing this issue and asked her if she'd mind looking for some numbers. She thought I was kidding and told me to just come back and get my list (way on the other side of the plant). On the third hit on her list, she asked me why I was asking her for these numbers if I already knew they were there. She didn't believe me that I could hear the failing drives but I was able to get over 50 this method; I think I missed about 5. There were areas of the plant that had workstations I never knew to look for, but they came to us soon enough.

    The OP mentions mold. As a resident of central Texas, I think I can safely say that mold is evil. Once you get a little, it's really hard to get rid of it all, and any mold infestation will have serious health implications in the short and long term. I realize that it may be painfully expensive, but if you suspect any mold on anything, you should either quarantine it until you can thoroughly kill it or just trash it. A basement with two sump pumps suggests to me that it's not a typically dry place. If this is the case, you're in pretty rough shape structurally -- I hope you can afford a good mold removal service. If there's any delay while you save up money or have to wait for service availability, get a good dehumidifier for the affected spaces and make sure that it either drains properly or is emptied regularly. Cutting down the humidity will hinder further mold growth, although it shouldn't harm what you already have.

If you take your foot off the gas early and coast down to 20 so you don't need to stop at a red light, you burn less gas than staying at 55 longer and having to accelerate from a stop. As a corellary, increase stopping distance in traffic whenever you don't see brake lights (traffic speed minus 1 or 2 mph), decrease when you see brake lights (but maintain safe distances). This will absorb some accelerations and remove some braking in addition to improving overall traffic flow.
