  1. Re:Not plastic, titanium on 3-D Printed Pelvis Holding Up After 3 Years · · Score: 1

    This is all well and good, but don't forget the application here: an artificial pelvis. It doesn't have to be super-strong, it only has to be as strong as something made out of living cells and a bunch of calcium. An artificial titanium pelvis taking up the exact same volume as a natural one should easily be stronger, no matter what kind of process is used to make it. It's not like our human bones have strength-to-weight ratios challenging forged titanium.

    You sound totally paranoid. If you want to be quite reasonably secure and have WiFi, all you have to do is make sure you're using WPA2 encryption. Better yet, make sure you're using an alternative firmware like OpenWRT or DD-WRT, and keep WPS and uPnP off no matter what you use.

    I don't think I've even heard of someone getting their WiFi hacked when WPA or WPA2 was being used; people only get their home WiFi "hacked" when they either use no security whatsoever, or WEP (WEP is trivial to hack). And even then, people only "hack" them so they can get free internet access, or maybe send funny stuff to your WiFi printer, not so they can search through all your files. Think about it: the only way to hack WiFi is to be physically on-site. How many people are going to drive around from neighborhood to neighborhood looking for WiFi networks to hack from their van, so that they can then try to hack into your computer from there (several orders of magnitude more difficult a task)? No one is going to go to all that effort so they can look at your pr0n collection. The really serious hackers are doing it from eastern Europe and Russia, and they come in through your regular internet connection; WiFi is irrelevant here. And the information they're after is likely your banking information, and since it's impossible to access your bank's online services from an old laptop that isn't connected to the internet, that isn't helping you either.

    The blame for this should be laid squarely at the feet of the router manufacturers.

    Ok, what good is that going to do? So a bunch of people get their home routers hacked, and you point the finger at the router mfgrs. Why should they care? What are you going to do about it? Declare that you're not going to buy from them any more? Haha, like they care; their customer base isn't Slashdot users, it's regular Joe Schmoes who don't read Slashdot or tech news, and just buy whatever the Best Buy salesman or Comcast representative tells them to buy. Moreover, Joe Sixpacks have a long history of never blaming mfgrs for security problems, and instead laying the blame squarely at the feet of "the hackers", as if that's going to do any good.

    IMHO, here's what Linksys/Cisco/Netgear/etc/etc/etc/ should do, at the very least:

    Why should they? What are you going to do if they don't? Give them a bad reputation? They already have a lousy reputation among Slashdot-folk, and it isn't hurting them any.

    1. Be open and forthcoming about bugs found in their router software

    Why? This will just make their products look bad to the Joe Sixpacks. Better to keep it quiet.

    2. By default, routers should ship with automatic firmware updates enabled.

    I'm not sure why they don't do this already, but it's probably because there's a chance something can go wrong with a firmware update, resulting in a bricked device; better to just ignore the problem and let the device run with an old, known-good firmware, because then Joe Sixpack will see that it's working and not blame the mfgr.

    If I'm at BestBuy/WalMart/etc. and see one router boldly telling me "We care about your security! To protect you and your data, this router will check weekly with $manufacturer and update itself to give you the most secure Internet experience possible." And it's sitting next to another router that says no such thing, I'd buy the one that will keep me safe.

    This is a pretty good point, and again I'm not sure why they don't do it already. I think someone else in this discussion said that Apple's routers actually do this.

    7 miles might not have helped there; Katrina devastated far more than 7 miles of coastline. If your business/datacenter and your backup site are both on the coast, 7 miles apart, they'll both be toast when a hurricane hits. You have to go inland, and hopefully more than 7 miles. Of course, the problem in places like the Gulf Coast is that all the development is right on the coast (or within a few miles), and immediately inland (past the few miles of development) it's all rural. So if you want to store your backup tapes someplace inland 15 miles, you'll be putting them in someone's barn.

    Um, unless I'm missing something, a tape is only going to be able to store its native capacity, and that's it. It's not like they're accidentally going to put twice as much footage in there on some of them. If the native capacity is 800GB, that's it.

    If you're storing up to 5TB on a tape, that surely must be because the you're availing yourself of the compression feature (rather than storing pre-compressed data), and some of your data is highly compressible. This isn't usual; different data is differently compressible. If you're trying to store h.264 movies or JPEGs on a tape, you're not going to get very good compression, and probably none at all in fact. If you're storing text files, you should be able to get excellent compression.

    Exactly. "pwnies" even says in his posting on Reddit how MS looked at adding multiple desktops to Windows, but in testing they found out that casual users were confused by them. Because of this, they took them out.

    I use multiple desktops on my two computers that run KDE, and of course I use the feature a lot. My wife uses KDE on her laptop too, and she's definitely NOT a power user. Does she get confused by multiple desktops? Nope. It's really simple: I never enabled that feature for her like I did on my computers.

GoT isn't even filmed in Britain, it's filmed in Ireland (and Iceland, and Malta). Moreover, the whole society of Westeros is portrayed is horribly flawed, as all the humans are busy destroying themselves while the undead from the North invade. (Esteros isn't much better; one city is built on slavery (now destroyed), another is built on unrestrained capitalism (now looted), and the Dothraki are just a bunch of savages.) Honestly, I don't see any real parallels between GoT and real life, unless maybe the White Walkers are a metaphor for global climate change. Personally, I'm rooting for the White Walkers. The humans are just too stupid.

    Maybe, but there's a lot more to a car than the electronics. A mobile phone or laptop or tablet has nothing but electronics (unless you count the battery or the hard drives (laptop only)). Cars have a big electric motor which needs its own control system and cooling system, wheels, hydraulic brakes, suspension, steering, air conditioning, a chassis designed to be survivable in crashes, airbags, seats, and lots of other mechanical bits and pieces. Yes, there's a lot of electronics in a modern car, but there's lots of mechanical stuff too, and that stuff is all life-critical. This isn't the case in a tablet computer. The electronics in a car have to work in all weather conditions, at all times, with no rebooting. If your tablet craps out and has to be rebooted, it's not a big deal. Trusting a trendy, form-over-function consumer software company to make mission-critical systems and software and worse yet survivable chassis structures is a disaster waiting to happen.

    Hey, I never said it'd be cheap, just that the technology mostly exists. We have excavating machines, we have the technology to operate things remotely....

    Besides, we don't necessarily need to operate all this stuff remotely. We should be able to set up a very small habitat for a small crew to man, and have them operate the equipment on-site until they can build bigger and better more-permanent habitats.

    And it isn't just the machine to do the tunnel boring, you need structural materials to support the excavation and all the other building materials for the base.

    A better plan is for us to figure out how to jump-start mining, refining, and manufacturing operations on-site, so we don't need to transport all this stuff from the Earth.

    So we're going to rely on hypothetical tunnels to shield us from radiation? Great plan...

    Along with mining and manufacturing on the Moon, this too requires something called "exploration": we need to actually send probes, or maybe more manned missions, to the Moon to learn more about it to figure out what can and can't be done there, and how. We're not going to find out whether these hypothetical tunnels exist or not by sitting on our asses here. At least the Chinese are putting an effort in to explore the Moon further; we certainly aren't. I'm not advocating sending a bunch of TBMs to the Moon next week, I'm just saying most of the tech is already there, it just needs to be adapted some, and we need to figure out how to build it using materials on the Moon.
