  1. Re:Then again... on Decrypting the Secret to Strong Security · · Score: 5, Informative
    If you're going to use asymmetric crypto for legal purposes, to sign stuff, for instance, then the secret cannot be easily changed (unless there's some sort of central repository of keys that actually authenticates you properly when you ask to change your key, but even that is a bit dodgy).

    I don't think it's quite that bad. Imagine you are maintaining a repository of signed documents (eg security patches for an OS). You sign these with a private key and make sur ethe public key is widely advertised, so people can check that your documents have not been compromised.

    Now, assume your private key is compromised. This is bad but not the end of civilisation as we know it. You can make sure the world knows not to trust that key, at which point is as if your repository had never existed, and you are starting from scratch. You would need to get your documents back from a trusted archive (you did take backups didn't you:-)), and sign them with a new key pair. You are back in busines as soon as the new public key had been recieved and verified by enough trustworthy people.

    So, loss of the secret is a big pain in the arse, but not disasterous. Just how painful it is depends on how well you have planned, eg having that trusted archive, having channels to quickly disavow your compromised key and the network of widely trusted people who know how to check that your new key really came from you.

    in a legally signed document scenario, you might arange for an electronic notary to annotate your document with the date you signed it and then sign the annoted document. Then people could tell whether the document was signed before your key was compromised, and a fraudster needs to get at both your secret and that of the notary.

    The problem with hierachies is, except in rare cases, the order is irrelevent. Did you file last yeat's invoices under `invoices/2002' or `2002/invoices'? As things get more complex the number of options increase. just being able to say `give me invoices to Fred's widgets from 2002' with the keywords in any order is much better.

    A Unix example is all those bin directories. Where do you put commands which are specific to this host? To this kind of machine, to this organisation, to you, but only on this kind of machine... To be able to create a folder and just label it as `commands, for fbsd, for desktops', knowing that people can find it by looking for `commands for fbsd' if they don't care about your desktop/server distinction would be good wouldn't it?

    I think it should cover the difference between OpenBSD and Linux, since many people are switching from Linux to OpenBSD, nor?

    Who's gonna read a huge list of smalldifferences in command line switches and file locations? The BSDs have worthwhile documentation in any case, so man-whatever will get most of this information.

    Similarly there is little point in having chapters about how to do IPsec or whatever. Online resources are much better and can be kept up to date as things change.

    The only thing a book is really good for is talking about fundamentals. The kind of stuff where, if you ned to know it, you would go sit in a comfy chair and study. taking McKusick et-al as a model and writing up information on the newer and OBSD specific things would produce something well worth paying for.

    It is because we have 10 fingers. Learning to count with fingers is easier

    But the point of a written notation system (or a mechanical counter such as an abacus) is that it replaces counting on your fingers. So the accident of history is that whoeer invented positional notation didn't notice that fingers are irrelevent.

    In fact, once you have worked out how positional notion works, base 10 becomes stupid to use on your fingers. 6 works much better (you can count to 35, and division by 2 and three is easy). Binary even better in terms of how high you can count. 60 gets them all, but is too large IMO

    Works fine for angles and time. And people have no problem working base 100 for length in metric systems.

    One cubic centimetre is one millilitre, no matter which way you cut the cake. Litres are a measure of volume, as are cm^3. It's just a different and more convenient name.

    This is only true since they changed the definition of the litre.

    And, of course, the pressure used to define centigrade degrees (and hence kelvin) and the water volume to mass relationship betwen the decimeter and the kilogram is arbitrarily chosen. So the whole mess is just as arbitrary as any other choice.

    All I want is a system that allows easy conversion to other units. None of this 2 cups to a quart; 4 quarts to a gallon, a dozen gallons to a bushel and a peck....

    Surely, the fact that the cups/pints/quarts/gallons etc system is base 2 should make it the system of choice for this audience.

    The traditional measures (`English' to Americans,`Imperial' to the British) are not as arbitrary as many people for some reason think. Volumes are base 2, because halving and doubling volumes are easy operations to do by eye. Many other things are base 12 or base 60 because these are good when you have to do mental arithmatic. there are, of course, oddities as you'd expect from a system which evolved in use.

    Base 10 is a really bad choice for anything except paper and pencil arithmetic, and only that because of an accident of history gave us a base 10 notation system. Just think how much easier life would be if whoever it was who invented positional notation has used base 12. No one uses their fingers when writing down numbers, so the link with 10 is spurious and just serves to make division and multiplication harder.
