  1. Re:Other Number Theory Tricks? on There Are Infinitely Many Prime Twins · · Score: 1

    Remember being taught to convert recurring decimals into fractions? Taking 0.3 recurring as an example - the method I was shown goes like this.


    let x=0.3333333.....
    10x=3.3333333....
    10x-x=3.33333 .... - 0.333333....
    9x=3
    x=3/9=1/3


    But if you try the same thing with 0.99999....


    let x=0.99999.....
    10x=9.99999.....
    10x-x=9.99999... . - 0.99999....
    9x=9
    x=1


    I guessed the answer to this quite quickly but had to look up the proof (I wasn't entirely convinced initially).

    This is interesting.

    I know Conectiva is the most popular distro in Latin America and so I guessed that it might be used by more people than slackware. To find it not even in the top 100 makes me wonder if the sampling method is biased.

    Could it be for example that internet access is very poor is SA even among those wealthy enough to own computers? Perhaps non-English speakers are less likely to access distowatch? Maybe something else is skewing the results . . . interesting.

    Conectiva Linux isn't generally well known outside Latin American but it's used by a huge number of people just the same (more than slackware I'll bet).

    However I have little doubt that this distro will also change over in due course.

    I presume that you are not a resident of the UK, if you are then you're extremely ill informed about the laws. You do not have to be "a farmer" to own a shotgun. I personally know several people who own shotguns but are not farmers or sport shooters (all but one of them licensed owners). UK law merely requires that you can store the shotgun securely, do not have a criminal record, and have some kind of legitimate reason for wanting one.

    My personal experience of general opinion "on the streets" and the BBC's version are inconsistent. The BBC like every large organisation has it's own axes to grind. Do you also believe everything you read in a newspaper?

    Blair recently called for a referendum on further integration into the European Union and was met with stunned amazement by the pro-European lobby, generally everybody seems to know he doesn't have a chance of winning and the pro-europeans expected him to push the UK further into the (anti-democratic) EU against the general will of the population.

    No real help is given to new users and such an elitest attitude is suicide.

    A number of the reviews and guides I looked at before deciding on OpenBSD warned me about the communities attitude to this. But, firstly - I guess it's an understandable attitude if you aren't really concerned about promoting your OS and just want to be able to run it yourself, let's face it most of us are really freeloaders (I can't hack kernel code can you?). Secondly, the only time I've ever asked for help was on bsdforums and I got two quick and helpful replies, without any abuse at all so I'm not sure their reputation is entirely justified (but then I did RTFM first).

    how many people use OpenBSD

    I don't know, all I know is - I use it . . . and I'm not a real "hacker" or professional sysadmin so I'd imagine there must be quite a lot of people using it. I use it on my home "server" and use linux (mandrake) on my laptop.

    I really like OpenBSD it's got an absolutely rock solid and professional "feel" to it which I've never got from any Linux distribution (and I've tried quite a few). It's also reassuring to know that you're using a notoriously secure OS, of course I assume that "anything is hackable".

    I've been looking through the documentation to see if there's an easy upgrade method but haven't found anything really helpful so if anybody can give me a pointer I'd be grateful (I don't fancy a full re-install!).

    Why would you want to emulate one with the other?

    Despite the old joke about how the only vi command you need is :q! not being true. You really need to know very few commands:

    • vi whatever.conf - open a file
    • [esc] - enter beep (aka command) mode
    • HJKL - move the cursor about
    • x - delete character
    • i - insert stuff

    This is enough to correct a config file and get things going again - all the rest is window dressing.

    Ah but . . . if you want your copy on the e-paper then you would have two copies (one on the repository and one on the e-paper) - obviously you'd need some kind of DRM to ensure that the original was deleted as it was downloaded. The best system would be for the Copyright Police to control the e-paper and the repository, then you request the transfer from them - they can check you are authorised to view the text and make the actual transfer. Fortunately the Copyright Police will be monitoring all transmissions anyway (to ensure that proper DRM is being observed) and watching through CCTV to make sure you don't show the book to anyone else.
