  1. Welcome to Slashdot. on The Ham and Spam of Weblogs · · Score: 4, Interesting

    Slashdot is a blog, created in the context of a news site, which we all come to and bitch about things we want out of technology, think is/are cool, and/or hate and want everyone to know why.

    That being said, Google (along with other large search engines) have already taken stances on blogging, and are actively pursuing their individual stances. For most, this is creating their own blog service, and doing some shifting in their code to make sure blogs don't come out on top. But this isn't an absolute truth.

    If you want these things, and Google doesn't offer them, make your own search engine, and do it better. No, seriously, don't look at me like I'm crazy; there have been over a dozen "major" search engines created after Google, some are only in serious use by geeky populations (AlltheWeb, as far as I can tell, fits this), some by the trendy, some by the "I hate Google"ites, etc. etc. It's as simple as that.

    One reason I think Google's strayed from taking such a hardline on blogs is simply out of ease of use. Google doesn't want to complicate life with a million more search options, especially ones you can deal with yourself by subtracting out the majorly offensive sites (-livejournal -blogger -blogspot, etc).

    Umm, don't normal nuclear reactors require the waste be stored somewhere?

    If we used fusion reactors, this wouldn't be such a problem, but all attempts as of yet have failed to make fusion an energy-profittable system.

    For fission to work right, we really need to use the fuel up. Current laws say that you're tapped out once you've fissed just a tiny fraction of the energy available. This means more mining for more uranium, which means even more environmental damage.

    Windmills are closer to being non-environmentally harmful... more birds will die due to loss of living realestate than due to running into a fan blade.

    Better yet, solar panels (or even heatpipe-driven systems) are infinitely profitable. Build them once (huge cost, I know.. but isn't any energy facility?) and they'll suck down power for as long as you want them to. Most are constructed ruggedly enough to take just about any kind of abuse; they've gotta sit under the sun 10 hours a day!!

    With a heatpipe system, it'd be like running a geothermal system in reverse. Not sure at the feasability of this for power creation, but we should definitely investigate it out west, in the desert where most of the sun's energy is going to waste anyways.

    RAID is a means to an end. I never said it was a backup medium; the hard drive is the medium in which RAID operates.

    RAID controllers are a great way of mirroring data on a drive, without having to run a program to do it. If you're worried about accidental file deletion, you've got a LOT more to be worried about, especially with digital media. If you've ever worked with it, you know that there's almost never a reason to delete anything. I know people who still have video clips from work they did in the early 90's on their macs. In fact, I know a lot of people who simply use hard drives as "write only" memory, with absolutely no intent on going back to the information in the next year.

    As for the linux-HA guys who say not to buy the same disk drives, that's their personal preference. Linux people tend to like older, more strange hardware, and that's good for them. But to us in the business who need things to work, we like to buy in bulk, a lot of the same drive. That way when one or two do go defective, you can get them replaced in an array with an identical match. And you can bet once you up the hard drive count above 5 that at least one of them will be defective.

    Lastly, timestamps are unreliable. You never know when a machine will have a bad system clock, or won't sync correctly with a time server. MD5's are (AFAIK) still reliable (Yes, I have heard of some people who've broken it, but I don't believe they've done it for trivial cases yet). But it's still one more piece of information you have to keep up with..

    The problem with data retention is simply that it's messy and expensive, and there's a hundred million ways you could never think of that something could go wrong (ever heard of the moths that ate old tapes? That'd really suck. How about a freak event like a solar storm to wipe a few bits here and there from a drive? These things are crazy, but they do happen.. (well.. maybe not that last one, but it gives you something to think about.. :).

    Sorry if I seemed trollish.. but you just went into a lot of application specific detail that I didn't want to go into myself.. It's a lot of work designing those backup systems and failsafes.

    Yeah, but in three weeks if your system dies, you can completely recover with RAID; with tape it can be done, but it takes much longer to restore, and check for data integrity. With RAID, the integrity is built in.

    People trying to argue RAID isn't a backup medium obviously don't understand backup. RAID is just a means of getting two copies of the same data on different hard disks. *You* are the one responsible for making sure that data is safe past that (which goes to my suggestion of storing the set of parity drives in a firesafe location).

    Quality hard drives are built to last. Especially if they sit around, not moving, in a static free environment. Sure, they have more failure points, but that's not what I'm arguing, and that's not what backing up to harddrive is for. And for the last time, RAID is a means to an end.

    The thing about a Game competition is, that it allows for so many different strategies, that anyone can come up with one, code it, bring it to life, and have a chance to win. Therefore, games make really good contests.

    Of course any game competiton will run many different iterations due to the fact that so many things either have to be randomly generated, and the bots my behave differently in different environments.

    The thing is, if this was a program to do database sorting, nobody would care (or anything else randomly that can pop off your head; let's face facts that most programming tasks suck. That's why we're writing the damned program in the first place, so that someone doesn't have to do it by hand!!!). So really, it is best practices to make a competition a gaming competition.

    These particular rule sets, I'm not very happy with, but that's personal reasoning. And any game theorist will tell you that anyone's got a fair shot at this; the search space is so great that nobody will have any marvolous breakthroughs, and it's more of a game of chance.

    While RAID was originally meant for data security, availability, and consistancy, it has a lot of other applications that weren't in it's original design.

    First of all, disks are *so cheap* these days, hard drives are a more than acceptable backup medium. As disks tend to be identical in size and construction if you buy in batches, disk-to-disk backup is quite the good system, just as long as you don't always keep the disks in the same location (aka, not even on the same controller! *gasp*)

    Secondly, you went into a lot of specifics that I didn't care to; a lot of backup systems are custom tailored to the situation.. so while this kind of system might work great for you, I doubt if it would work so well in this case, especially. Digital media tends to be very non-compressible, very volatile media. That being said, operations like MD5 are very crucial to insure the data from one location matches another, which means even more precautious MD5 storing measures. You're also dealing with larger files which means rdiff is almost entirely out of the question.. I could go on and on about different, application specific schemes, but I feel I did good enough with suggesting three different mediums and to have at least two copies of two of them, preferably in 4 different locations.

    I concurr. For digital media, I would definitely do two of at least two different back up strategies.

    First that comes to mind is Tape backup. They store huge about of data, and are very cheap these days, and have been proven to last for a while. Keep a good backup schedule, and keep one copy of the tapes offsite.

    Secondly, I'd do optical. Optical's cheaper, but it's also not as long lasting, and takes longer to make the actual back up.

    Thirdly, I'd do RAID. Mirror all the files onto a second set of hard drives. If you really want to get paranoid, mirror onto two sets of drives, and once a week swap out a copy of mirrored drives from a fireproof location.

    If your data is truely irreplacable, then this is a good regiment. But it's also very expensive.. so you'll have to make up your mind.

    And yes, the game is actually too hard. That's the whole point; it's a fair game. Nobody's going to have any chance better than anyone else unless they design their algorithms correctly. That takes all of the guesswork out of the game, and ensures the playing field is fair. It also adds a lot of variability to the game, allowing for a huge amount of possible attacks at the game.

    Certainly, raster bitmaps (as they are in images) can also be represented as vector bitmaps (as they are in text; think linear storage matrix), or as Fourier matricies, or as (...). While the human eye can look at such a pattern and quickly grep a certain meaning, another organism's eye may look at the same pattern and grep an entire different meaning.

    The quickest example I can think of is a colored bitmap. What colorspace are you using? RGB, we'll assume. So what order are the colors in the image? Red Blue Green? Perhaps Blue Green Red. And what if they made a different assertion about the color space? Perhaps another being uses CMYK natively, and a 3 byte colorspace then becomes an aliased 4 byte colorspace, distorting the image to noise.

    The problem is assertion. We can't make broad assertions when making translations, especially when we are dealing with assertions to something as significant or insignificant as a bit. (something we'd have to assert as two values ;)

    If you want to think about it further, all data we generate inside of a computer is a "bitmap". A certain number of "bits" will "map" to a certain object. Thus, your entire argument really doesn't make much sense, and still reveals the former problem, "how do you read something without knowing how to read it?". Your bitmaps could be interpreted in 16, 28, 64, 13, any number of different combinations of bits, and technically be just as correct any other logical implementation, even if it doesn't produce the same conclusion.

    The problem is, we need to pass the "map" portion of the "bitmap" on. Aliens won't be able to read our bitmaps simply because they won't understand what maps to what bits. If we can convey that message to them, then we have conveyed the message. We first need to pass the concepts of "bits", then the concept that a pattern of "bits", "map" to something. Then we need to pass the information of what exactly they map to. Then, and only then, can they perform the last step of the translation from bitmap to image.

    The problem is not a simple one, and there is no right answer yet, simply because we haven't ran into any "aliens", or people in which we have absolutely no cultural, physical, or logical common ground to. Even with nations as dissimilar as Japan and England, for example, we have common objects in which we can use to pass meaning. With an alien race, we might not be so lucky. Eventually we will find a way to overcome the problem, but only when the problem is actually occuring; there's no way to "prepare" for an alien species other than to be ready to have an open mind and some lucky would be handy.
