  1. Re:Print to film is probably a good fallback plan on Afterlife Will Be Costly For Digital Films · · Score: 1

    The color really isn't that hard. As long as you have black-and-white film that can hold the number of bits of each channel (R, G, and B) in the color image, you could just have three film frames for each color frame in the original. You don't actually need color film to record color images; three black-and-white ones will do fine, and are pretty easy to reconstruct.

    You could even use more frames in this manner to achieve greater bit depths per channel than the film supports (use one frame for the first 12 bits of the channel, then another frame for the last 12 bits -- thus, 24 bits per channel). Thus with six film frames per actual 'frame' in the digital version, you could get RGB at 72bpp, if you wanted such a thing. Used this way, gamut is not a problem. You could even throw in another frame with nothing but error-correcting data.

    The nice thing about the one-frame-per-channel encoding is that, in the very worst case, you can always rig up some sort of analog projector with three different colored lenses and get a crude color projection out of it: not even digital technology is required. But of course, if you make the pixels big enough relative to the grain structure of the film, you can always scan it and get a pixel-perfect digital version back.

  2. Postal mail used to be pretty good, too. on Email In the 18th Century · · Score: 4, Interesting

    I was reading something recently that discussed the US Postal Service in the late 19th century. In some major cities, like New York and Boston, the mail used to come as much as five times a day. That meant you could write to someone (local, served from the same Post Office) in the early morning, have it picked up in the first round, delivered in the second, have their reply picked up in the third, and delivered on the fourth. (And you could even send a reply back in the final pickup for delivery the next morning.) That's pretty good -- some people I know don't even check their email that often!

    If you wanted service and delivery times that good these days, you'd need to go with a courier service.

  3. There's a pretty big difference. on Australia Plans to Censor the Internet · · Score: 2, Interesting

    This is a slippery distinction made between the two domains in the context of "free speech". You would have the .kids domain restricted by a peer review committee and that's just dandy. But that same philosophical application somehow does not work for .xxx? Well, there's a valid argument as to whether we should even bother to 'protect' children from pornography, rather than trying to educate them as to the differences between healthy and unhealthy sexuality, reality vs fantasy, etc. I think that's a valid discussion to have, and in an ideal world, I'd be all for education rather than enforced "innocence", but I realize that's a non-starter in most parts of the world today.

    So, if we take on premise that children need to be 'protected' from some content, I think it's more practical and less philosophically repugnant to create safe-zones around children than to try and 'child-proof' the entire world except for certain 'adult zones' where we allow uncensored conversations to take place. Basically, if you go into a kids' zone, you agree to self-censor. If you don't want to do that, you don't have to go in.

    Similarly, if you wanted a site in .kids.us, or some other "kindernet," you would have to go through some sort of review process, or perhaps post a bond and swear that you'd keep it clean. If you didn't want to do this, you could just get a regular domain and not worry about it -- the only customers you'd lose would be the ones whose browsers don't let them access anything outside of the kindernet.

    This is a pretty fundamentally different process from trying to censor everything that's in the general TLDs and force everything that's 'kid-unfriendly' into .xxx-type zones. Plus, while there's only one "general" Internet to censor and make child-friendly (meaning that you have to find one lowest-common-denominator standard), you can have many kindernets, corresponding to what different people feel is appropriate for different groups of children. You can have .kids.us and .kids.ir, for George Bush's and Mahmoud Ahmadinejad's ideas of kid-friendliness, respectively; you could also further subdivide .kids.us into .G.kids.us and .PG13.kids.us and the like for fine-grained control. Parents could feel free to enable whichever domains they thought were appropriate (and sites in more restrictive could automatically 'trickle down' to less restrictive ones; e.g. PG13.kids.us would be a superset of .PG.kids.us and .G.kids.us plus its own sites).

    Now, I'm not saying this would be the best solution -- I think the overall best solution would be to educate kids so that they won't be harmed by 'adult' culture as early as possible, rather than keeping them in bubbles, and I think DNS may not be the best way to signify the 'adult-ness' of content on a page -- but it's certainly better than trying to force all 'adult' content on the Internet into a 'free speech zone.'

    Are you just trolling or are you seriously this thick?

    Who'd want example.com when they could have example.xxx ? Why would anyone want the latter, particularly if it means they're going to be automatically censored in large parts of the country/world? I suspect there are lots of porn consumers who live blatantly hypocritical lives ("uh, sure, honey ... you can block .xxx, I certainly don't care about it..."). At any rate, it doesn't make much sense to restrict one's market. And with the price of domain names, the logical solution for any adult site would be to buy both: get yourname.xxx and yourname.com. This is the main driver behind the .xxx TLD in the first place -- it's a cash cow for the registrars.

    I think in time any pron sites left in .com will feel pressure to move to "where they should be". Pressure from who? And why would they care? Certainly not social pressure. There are porn sites around for lots of, shall we say ... fringe activities; things that are certainly not acceptable in mainstream society. No amount of tut-tutting is going to push them into the .xxx ghetto when there's a clear ongoing economic incentive to remain in both. And as for government/legal pressure, that only works within the borders of a single nation; there's nothing stopping me from setting up a .com porn site in some neutral territory and thus reaching all those consumers stuck behind .xxx-blocks for whatever reason. The only way you could enforce this is with a national firewall and universal content screening.

    And this whole scheme doesn't do anything about adult content that appears on sites other than ones 100% dedicated to porn. You're always going to have imageboards and interactive/user-created content sites that are going to tend towards 'adult,' because that's what people are interested in. You're not going to change that through any amount of legislation.

    The result is that no matter how much you try, there is always going to be adult content available in the 'general' Internet. And that means it'll never be "porn free," ever, undermining the whole point of the endeavor. You can't make the Internet, in general, "safe for kids," because the Internet is mostly populated by adults, and much of what adults want to talk about is, well, adult. So not only is it a recipe for censorship and unnecessarily burdensome, it's futile in terms of actually achieving its stated purpose.

    There's already a kids domain. It was a huge flop. Yep, very true. The take-away point here? Nobody really gives that much of a shit about protecting kids, or creating a 'safe zone' for them. The .xxx proposals are about two things: they're an attempt by the registrars to make a few bucks, and they're a way for some social authoritarians to try and regulate the lives of others' and censor the public sphere by pushing content they find disagreeable into a walled ghetto.

    But that would be too sensible, just like the notion of .xxx to enable easy filtering.
    Hold it right there. A .kids namespace and associated content makes sense; but a .xxx space does not, and would not work. They are fundamentally different concepts.

    A .kids TLD (or better yet, .kids.us or .kids.au or whatever) is a WHITELIST. You only allow content into it that's been reviewed, and is guaranteed-clean. It's trivial to restrict browsers to it. You can set up whatever kind of review committee you want to keep tabs on it. It's strictly opt-in by design.

    However, .xxx or .porn or .adult are exactly the opposite. They are BLACKLISTS and can only function when you effectively censor the rest of the Internet, in order to force adult content into the "adult" TLDs. This is hugely impractical and spectacularly dangerous from a freedom-of-speech perspective. Essentially what this tries to do is turn the entire Internet EXCEPT one corner of it into a "kids"-zone, and that's just not going to happen. It's impossible to police effectively without a national firewall (because unlike a TLD, which you could put under your country's namespace and easily apply national laws to, you'd be trying to censor all of the 'net), and such a scheme would lead to fragmentation of the network in short order.

    Do not confuse .kids, which is a good idea, with .xxx, which is dangerous and stupid.

Then you just go and burn it to the disc. Later if the file proves corrupted, you can use the parity files to repair or reassemble it.

    It's all open source, which is good for 'future proofing,' and gives you a lot more control than just recording multiple copies of the same file (which limits you to multiples of 100% redundancy).

    You could just stop caring about internal documents and eliminate or change the laws that depend on them. Treat the corporation as a 'black box,' in other words.

    I'm not sure why we should really give a shit about what goes on inside a company. What matters is what it does. If a corporation does something bad, punish it. I don't really care, and I don't think it should matter, whether people in the corporation "knew" what they were doing was bad, and that's mainly what the retention laws are all about. They exist in order to make it easier to pin down when so-and-so knew something. If you just tell companies you don't care, and enforce rigorous strict-liability doctrine (on the corporation -- I don't really agree with strict liability as applied to individuals, but that's a separate discussion), you can leave the internal policing to the corporations themselves.

    The idea is that basically, you make the corporations responsible for the actions their employees take in their name and the results of those actions, whether intentional or not, and whether the harm was foreseeable or not. Leave it up to them to decide how they want to manage risk and how much freedom they want to give employees to act without authorization.

    I don't really see why we need to peer into companies in order to regulate them. If a company wants to keep its financial records in cuneiform impressed on wads of sodden toilet paper, that's fine by me. The market will punish them for it when nobody wants to buy their stock because there's no way to gain any insight into their performance. Maybe the stock exchanges would even enforce minimum accounting standards for listed companies, as a way of keeping the crap out. But caveat emptor -- do your own research, and don't come whining to anyone else if you put all your money into a company that implodes. If you want secure investments, that's what savings accounts are for.

    Similarly, if a company pollutes or otherwise externalizes costs on the public, punish it. If they don't cough up payment for the externality, forcibly seize whatever physical assets they have under their direct control and sell them at auction.

    I can train my dog without knowing exactly what's going on in his head every moment; that's exactly the philosophy I'd apply to corporate governance.

It's very much man-vs-nature in the standard Imperialist mode; hardly "harmony.") Real pre-technological life, particularly in tropical or desert climes, is pretty rough. And based on the only even arguably objective evidence we have available -- people's preferences over time -- once people are exposed to technology, they choose to use it. You see those choices happen over and over: children grow up, they have a choice between two cultures, and they pick one. It's a rare group that can hold out and make a low-technology lifestyle attractive enough to ensure their own preservation as a community (e.g. the Amish).

    It's easy to speculate about the nobleness of pre-technological life and getting 'back to nature' in various forms, when you're sitting at the pinnacle of 6,000+ years of development.

So long as a scientific theory consistently offers a logically coherent explanation of observed reality, we give it credence until new evidence comes along that contradicts the theory. If ever such evidence comes along, or if a theory comes along that does a better job of explaining observed reality - better meaning it possesses greater elegance, comprehensiveness and simplicity which we lump together under the term 'parsimony' - we either modify the original theory or toss the theory out. That may be your definition of science, but since I don't see any way of quantifying "parsimony" I think it's edging very close to being a crock.
