    The thermal images you linked have to be the scariest of the the set. The center of the gash is clearly not insulated as it's a dramatically different temperature than the exposed tile material around it. IMO, it illustrates how bad the situation is better than the optical images we've all become familiar with thus far.

    I'm convinced. Attempting to land this orbiter without repair would be like attempting the same with the windows open.

    You're pretty much on the money for this being good for space tech. I forgot about that particular cold frontier in my post. I guess you can paint me fixated on how the current crop of electric/hybrid cars will never catch on in places like Alaska, despite people painting them as some sort of panacea.

    Anyway, the heater for the electronics in the Mars rovers(and by extension, probably some spacecraft) is nothing more than a boring slug of plutonium (or something else radioactive). The problem with dust collecting on the solar cells is a more of a mission viability issue when you get down to it: no sunlight, no power, no worky. As the rover has no RTG installed, once the solar cells get choked with dust long enough for the batteries to drain out, that's the end of it. It has nothing to do with keeping the electronics warm. :)

    But your point is still valid. A "space-grade" battery would add a little extra insurance against freezing, for practically no extra weight. That's typically the point where aerospace starts to get interested in a particular piece of tech (lighter, better, cheaper), so maybe we'll see this developed by NASA yet (?).

  5. Gears? on Building a Fast Wikipedia Offline Reader · · Score: 1

    I didn't see any posts on this so I thought I'd bring it up. I think the author took the long way around.

    The author did some nifty hacking that resulted in the following stack of dependencies:

    He cited not wanting to use a RDBMS since he's not writing to the database, just reading. I can give him that, but it seems like it caused more trouble that it's worth.

    This leaves me wondering: why not just use Google Gears and be done with it. Sure, the hacking part would shift largely to the javascript side of things (would be mostly wiki conversion), but you'd have the other bits (web server, and storage) already worked out. All you'd have to do is slap together some little app to insert the XML data into the database.

  9. Re:Typical misleading summary... on 8 Million Year Old Bacteria Thaws, Lives · · Score: 1

    You have to keep in mind that the theory of evolution only really applies in terms of fitness against the current environment, not all environments along a species' lineage. Genetics has a habit of turning off or outright dumping genes that don't matter when there's no selective pressure to keep them.

    Another aspect of evolution is that it acknowledges the notion that you can't be awesome at everything. That's why everything keeps changing, and that's why organisms are constantly dropping traits as much as often as they're gaining them. Biologically, its cheaper to stick to what's necessary, which in turn, makes an organism more successful and likely to reproduce.

    Another thing to keep in mind is that every single last evolutionary advantage ever gained by anything, happened by complete accident. Eyes, brains, gills, lungs, hair, skin, flowers, fruit, leaves, the whole mess one long litany of screw-ups that turned out to be useful. Being able to survive in a deep-freeze for 8 Million years could easily be yet another such mistake.

    So 8 Million year old bacteria might have some capabilities to it that might make modern flesh-eating staph look like a bad rash by comparison. Then again, it might be laughably fragile when pitted against an strong beer yeast. The problem is that you don't know if it just happens to be really good at munching on mammal flesh, just by looking at it.

    That's why it's stupid to just take it out of the cooler and go "hey y'all, watch this."

  11. Re:Trackball on Mouse or Trackball? · · Score: 1

    I can attest to how nice the Trackman is. It tracks very well, and the response on the buttons and scroll wheel is very good, even after years of abuse. Most importantly, it is *very* ergonomic - probably more so than a full-blown trackball.

    I was developing RSI problems in my forearm and wrist until I switched from a typical roller mouse to the thumb-ball. The initial learning curve was about 2-3 weeks, and after that I was able to match my standard mouse skill. The RSI issues (pain, tingling and random numbness in my arm) were gone by about the same time.

    The only problem I've had with it is that my skin is on the really oily side, so the contact points inside the ball-well tend to gunk up on me; YMMV. Fortunately, there's a pen-sized hole in the bottom of the unit that makes popping the trackball out a cinch. The optical window and contact points swab off very easily - it's easier than cleaning the rollers on a standard mouse.

    After two years of using a trackball, I'm able to flick the ball with a high degree of precision, making some tasks (and games) easier to do.

  12. Re:Big Changes, huh? on Small Electric Car May Usher In Big Changes · · Score: 1

    I'm going to take the devil's advocate here and say that our (American consumers) standards are too high these days for something like a Geo.

    By high standards, I'm referring to modern emission controls, side-front and passenger airbags, plus power steering and the rest of the stuff on your Metro. That stuff doesn't come cheap, and I'd wager if there were any way to get a car today without all that (extra safety, carbeurated-intake engine and all), it would work out to be nice and cheap. But there's no real way past all that due to federal regulations, so we're stuck with crap like the Kia Rio that clears these bars but pales in comparison to the Geo's reliability and construction.

    Then, of course, you could always buy one of the soon to be Chinese contenders in the market - but I'd recommend taking out an extra personal insurance policy *before* you get into one.

    Also the 10k pricetag on the Loremo there works out to 15k USD; not to mention that the maintenance cost looks to be on the high-side for a car of it's class ($600+/year - that's a lot more than a few oil changes). Plus, if you add on tax and tarrifs, there would be no clear price advantage at all - but at least the mileage looks good.

    2. Negatively affects ratings. Since most "cable companies" are subsidiaries of the entertainment conglomerates...

    The real WTF here is that this particular problem should've gone away a long time ago, unless I've misunderstood the present situation.

    With millions of cable boxes between Comcast, COX and whoever else is out there, why haven't they supplemented, or outright replaced the Nielsen ratings system yet? They obviously have the infrastructure, and could easily send out questionnaires to allow people to 'opt-in' for ratings participation (Brochure: "Hey, wanna keep your favorite shows on the air?"). As it is, the cable-co's existing DVR deployments are causing the same "dings" in statistics, even though they have 100% control of the game.

    3. Most consumers believe renting the box is a benefit.

    It's a benefit if you don't have a digital tuner, or even a cable-ready TV (old NTSC sets last forever) and don't plan on upgrading to either over the short term. Also you get free replacement in case the thing fails, which is kind of nice - even if the cable guy barges in with dirty shoes.

    Otherwise, I agree. The mere fact that I can't back up saved shows stored on my cable-co DVR is frustrating enough. Also the program browser software Comcast pushes is complete crap.

    Thanks, that was a good read. I think this is one of the reasons why these movies are going to stick around for a bit: they leave room open for interpretation and provide a fun framework for other ideas.

    For instance, my first thought upon seeing Neo's psychic abilities is that the "real world" was actually a nested (outer) matrix, designed to corral "non-believers" by providing them with a grittier, more believable simulacrum; it's so awful that it *must* be true. Smith's soliloquy in the first film provides some insight that indirectly supports the concept. :)

    No offense, but how did you get modded insightful? That just isn't true - don't forget that you typically tip at anyplace that serves food that's digestable. :)

    If you are routinely topping $7 to $8 a plate by cooking at home your either paying too much at the grocery store, buying "premium" goods, or buying your food partially prepared. If you cook with raw ingredients (meat, grain, rice, vegetables, spices and herbs), you can easily feed yourself for something closer to $3 to $4 a plate.

    The reality check comes in when you do the math: it should cost roughly $270-$300 a month (about $3 a meal for 30 days) to live by cooking entirely at home versus $1380 a month ($40/day + 15% tip) by eating out 100% of the time. So learning how to shop and cook for yourself is worth a much as $1000 a month. Even at $6 a meal, you're still ahead by about $400.

    Cooking in bulk, and freezing the leftovers, is another thing you should be doing as it's difficult to get economical results by preparing one portion at a time.

    Right on all counts for things here in the USA. Having minimized my budget for groceries for several years now, I've noticed that even buying stuff on sale nets me a buttload lot of sugar and salt and few vitamins and minerals. For the most part, if you want healthy food (outside of rice and beans), you have to pay extra.

    However, what a lot of folks don't realize is that this applies (for the exception of artifical market pressures generated by subsidies) mostly to chain stores that have min/maxed their business model to cater to customer tastes. As people get more accustomed to eating garbage, stores just put more of that crap on the shelves. For instance, I had to stop shopping at the local Safeway simply because the produce was routinely rotting in the bins since nobody was buying it. Stand outside for five minutes and you can easily see that few folks here know how to take care of themselves - it's just cart after cart of microwave dinners and sugar filled "juice-boxes" and ramen for the kids.

    One thing I have done is to go to "ethnic" grocery stores where everything is substantially cheaper, rather than shopping a large chain grocery store. Mark my words: immigrants know how to eat! The produce is plentiful and fresher, the meat is half the cost and tastier, I can get "exotic" ingredients unavailable elsewhere... who cares if nobody speaks English? In the case of the local Korean market, there's even a fishmonger where they'll clean your fresh fish however you want. The hispanic/latin markets around town also routinely have stuff like plantain and avacado for half of what you'd pay at the "normal" store.

    Cash-only staples stores (like Aldi) are another way to go, but I haven't gone that route in 7 years. They're awesome for budget shopping. I'd imagine that non-gourmet co-op stores might also be good move for most people.
