    Sorry, this is wrong in so many ways.

    Turing wasn't Church's student for the very good and simple reason that

    1. Church was in Princeton in the USA
    2. Turing was in Cambridge, England.

    They both came up with separate, original proofs that the entscheidungsproblem was not soluable at pretty much the same time; neither was aware of the other's work. Nor did they meet until after both papers had been published.

    Obviously the two proofs were logically equivalent but they could not have been more different and it was Turing, not Church who produced the blueprint for the first computer: the universal machine which can compute everything which can be computed. Even today we say of processors and languages that they either are or are not 'Turing equivalent' meaning that they either are or are not equivalent to the machine 'U'.

    Furthermore, Turing did not show that you could run the Lambda Calculus on U (although it was implicit, because U could run anything which could be computed, and Lambda Calculus can be computed, therefore U could run Lambda Calculus). It was John McCarthy who did that.

    My real question to Brits here is: How well is this burden accepted by the British people? Are the BBC TV and radio stations in the UK really non-commercial? I know the US government gives money to PBS and NPR but I don't know how it compares (especially per capita) to what the British government must spend on the BBC.

    The BBC is funded by a license fee which all owners of television receivers are obliged to pay whether they actually receive BBC broadcasts or not. Although the government collects this money and pays it to the BBC it's not really a goverment subsidy as it is a hypothecated tax - one of very few in the UK. So essentially we the public pay for the BBC.

    And although there's a little bit of grumbling I think on the whole we're very proud of it. I think we're very proud of the way it's prepared to stand up to the government, to oppose the government when it thinks the government is wrong. I think on the whole we're very proud of its committment to unbiased news reporting and high quality journalism. I think that if the government ever tried to control the BBC, or to cut off its funding, they'd face very serious public opposition.

They were not 'cool evil', they were just another greedy parasite, but, unlike Microsoft, a fearsomely efficient greedy parasite. IBM as a monopolist was far more damaging to our industry than Microsoft is now. You don't want them, or anyone else, back in that position. Seriously.

    I too have been playing this game long enough to remember when IBM were the big monopolist. At present, IBM are being reasonably good corporate citizens, but it has to be said that unless and until we get open commodity data formats for the overwhelming majority of interchanged data (and, to be fair, we are on the way there) the software industry is dynamically unstable and will tend to produce monopolies. I don't trust any large commercial software business to have the public interest at heart in the long term. This is not an attack on IBM in particular.

    OK, OK, I know that some of the board members of this company are people we most of us respect. And judging by what Bruce Perens, at least, has contributed to this discussion it seems they really believe in the idea.

    One cannot, in general, prove a negative. I've no doubt this company has diligently gone through every line of the kernel and reviewed it. But they have not, because they cannot have, diligently gone through every line of pre-existing proprietary computer code on the planet. The majority of computer programs are never released in source form, and it is not normally possible to reconstruct the original source by reverse engineering a stripped binary. So for the vast majority of legally copyright software out there, they did not have the source and could not compare Linux against it.

    But that, actually, is beside the point.

    By reading diligently through the code the company may potentially put something back into Linux; they may notice and report back to the relevent authors blunders, inelegancies and bugs.

    They may.

    But apart from that, they make no contribution back to the community. They are, in effect, another bunch of freeloading parasites on the community - the moral equivalent of head lice. They cannot have done what they say they've done, because it is a logical and practical impossibility.

  9. Re:Neverwinter, and graphics in interactive fictio on Interactive Fiction Competition Opens · · Score: 1
    Textual description, unlike textual input, is not something I consider optional in a genuine IF game (despite what I wrote in the Montfort review about how we shouldn't be so quick to leave games like Deus Ex or Half-Life out of the IF canon.) When I walk into the room and see your box for the first time, a true IF engine should do more than just tell me about the presence of the box. It should show me what I've found, in a way that graphics alone can't (easily) accomplish:
    On the table rests a small wooden box, carved of oak and stained with red wine or something darker. Fine scratches in the veneer lend the box a patina of antiquity, and a closer look reveals a spidery line of symbols carved into its lid.

    "The runes of Woznir," muses Anrael. "I've seen their power before, under very unhappy circumstances. If you intend to open that foul repository, I'll wait for you in the next room... or perhaps the next life."

    Again, I think you're raising objections without really thinking. Certainly there's no point (in Neverwinter) in writng that the box is on the table, because the user can see it's on the table. But you can, of course, add a rich textual description of the box which the player will see if they inspect the box. Sure, they right click and choose an eye simbol from the radial menu instead of typing inspect box , but that's purely a difference in user interface style.

    And there's no difficulty at all in Neverwinter in assigning NPCs speach acts triggered by (very) specific events. You could either surround the table with a trigger zone which causes Anrael to make that speach when he first enters the zone (or every time he enters the zone, or only if the box is shut, or...) or else you could override the OnOpen behaviour of the box to cause Anrael (if present) to make the speach.

    I'm not aware of anything you can do in any text-based interactive fiction engine that you can't do modulo user interface differences with Neverwinter. Nor, really, is there very much you can do with Neverwinter which you can't do (modulo user interface differences) with the best of the text-based interactive fiction toolkits.

    Good interactive fiction doesn't need (and doesn't have) graphics for the same reason that pictures don't make a good book any better.

    While I agree that interactive fiction doesn't need graphics, there's plenty of interactive fiction which does have graphics and which, in my opinion, greatly benefits from having graphics.

    For example, Neverwinter Nights and its Aurora toolkit provide excellent tools for creating interactive fiction with the ability to do all the sorts of things you can do in a text-based IF environment. But it renders these fictions in an attractive real time near 3D environment. The game engine does have some flaws - in my opinion it is based too ridigly on Dungeons and Dragons, and some aspects of gameplay are a bit mechanistic in consequence - but it is a worthy successor of such game engines as the Infocom ones.

    It would be possible to argue that Neverwinter is to Infocom as film is to printed books, but I think this would be a mistake. It is no harder or more complex to create IF in Neverwinter than in Infocom (indeed, I personally find it easier). It seems to me that Neverwinter and Infocom (and my own LISP based text game engines of twenty years ago) fall into the same category: frameworks for the creation of interactive fiction.

    As an aside, does anyone know of other modern interactive fiction toolkits which compare to Neverwinter Aurora? Much as I like it, I'd like to try anything else that's good and around.
