    Something about that makes the hairs on the back of my neck stand on end. Goodness knows how he feels today!

    I've got a copy of the ESA Bulletin journal from either January or February 1985 which was given to me years ago by a friend of the family - and one of the main articles is about the Huygens probe, in a form very similar to the final version launched in 1997. I think I ought to scan the article and post it online, just to give people an indication of how thoroughly planned these projects are. Unfortunately it's at home, and I'm in Brussels.

    Or are their safeguards in place for this kind of attack?

    Yup - each 'GUID' for a Bittorrent block is an SHA1 cryptographic hash. If you find a way of generating collisions for those, many computer scientists and mathematicians would love to know. ;-)

    From the FAQ:
    BitTorrent does cryptographic hashing (SHA1) of all data. When you see "Download succeeded!" you can be sure that BitTorrent has already verified the integrity of the data. The integrity and authenticity of a BitTorrent download is as good as the original request to the tracker. Checking the MD5/CRC32/other hash of a file downloaded via BitTorrent is redundant.

    I gather that if a client was pumping out corrupt blocks, or if they were corrupted at some point during transmission, they'd simply get dropped and re-requested. No idea if there's anything to permanently ignore a client that's pumping out nothing but junk, though - but on a busy tracker, it would get drowned out by all the others. Anyone know?

    Incidentally, is anyone else worried by the way the article concentrated on the distribution of television shows, almost to the exclusion of everything else? I've used Bittorrent quite a bit, but only ever for completely legal purposes - plus, I've always thought of it being a rubbish way of distributing dubious stuff, what with IP addresses of everyone downloading available straight from the tracker to whoever might be investigating...

    Graphics engines don't really need to become any better than the UT2 / Doom 3 / Crytek /HL2 ones. With those powerful engines and top-quality artists, you can display pretty much whatever you want.

    From a graphics point of view, the Half-Life 2 engine is actually fairly basic beyond its (admittedly pretty) shaders. It doesn't appear able to do volume-specific fog (as could Quake 3), there's no LOD on non-model geometry, and lighting for model geometry itself is derived from a single point, whatever the size of the model.

    But the second part of your equation is the most important aspect - it's the glorious artwork that makes Half-Life 2 look so lovely (to me, anyhow). The engine is 'good enough', and should allow Valve (and modders) to concentrate more on the gameplay and design aspects...

    I use Wikipedia only for casual information. I would never cite it.

    You shouldn't cite any encyclopaedia in your own work - use them as a jumping board towards new lines of research.

    This is why it's so important for encyclopaedia (and Wikipedia) articles to give references. Treat them as brief introductions and overviews of particular areas, and then do your own reading and work from the references. An encyclopaedia should never be the primary source of a particular piece of information.

    Wikipedia leans more towards the 'interesting general knowledge' use for me as well, and while I'd probably not use it for anything particularly serious, I do trust its content a bit more than that from some random web page turned up by Google.

    Personally, I really liked the ending - in keeping with the ultra-subtle, sparse storytelling, it has an ending which leaves almost everything to the imagination. The beginnings of a massive explosion, suggesting that you've succeeded in destroying the main Combine citadel, and some deliberately provocative words from the G-man, all wrapped up with a demonstration of how he can mess with the flow of time, pretty much confirming the 'stasis' Gordon must have been in between HL1 and HL2...

    I can see why some people hate it, and the manner in which the overall story was told, but try playing the game again. You'll notice a hell of a lot more, and notice some - ambiguities - in what some of the characters say, particularly Dr Mossman. A lot of her apparent 'betrayal' is down to an incorrect assumption by Alyx. Judith's actions are in fact entirely justifiable, but she's the one being maniuplated, in this case by Breen...

    It's not up to 2.2 yet, but Gimp.app manages to integrate into MacOS X in a surprisingly elegant manner. It's got a dock icon, which I drag photos from iPhoto on to; it can take screenshots with Grab.app; it can read images from the Mac clipboard. It comes as a single program package (Gimp.app, imaginatively) which you just drag-and-drop into your Applications folder, like any other decent Mac program.

    My only real complaint about it is the default theme - I've replaced it on my iBook with one called Milk 2.0 which manages to look a lot cleaner and smarter than the standard.

    There's this general opinion that The GIMP is somehow utterly impossible to use, but I really do disagree. I taught myself to use it very quickly some years ago, merely by sitting down and playing around with it. Compared with something like vi or Blender, it's absolutely brilliant - while it's a bit quirky in places, it's generally very consistent in how it does things, and menu entries are logically named and placed. There aren't multiple modes for the program to operate in (beyond indexed, greyscale and full-colour), and with a comprehensive help system, tooltips and so on with no hidden basic functionality, it's more akin to pico than vi... ;-)

    I started off using The GIMP because it was all that I could afford. I continue using it (towards my paid work as well as hobbies such as photography and computer game design) because while I could probably afford Photoshop these days, it doesn't really offer me anything useful in addition to what I already have for free.

    If you want to use The GIMP, try it with an open mind. Don't expect Photoshop, Paint Shop Pro or whatever, it's its own program in its own right, with its own advantages and disadvantages. Do appreciate that it's a cross-platform thing with its home on X11 and UNIX - the Windows and Mac ports are very close in user interface to the original, for ease of maintenance and porting. And above all, have fun. :-)

    As for the colour fading issue with different inks - I've been running my Epson Stylus Photo 1290 on proper Epson ink since I got it, and the photos I printed a while ago look absolutely identical to new copies I print. My father's got one in a frame and it's been up on a wall in a bright room for over a year, but no change...

    If you just want your holiday snaps printing, then taking the memory card to the local supermarket or photo outlet can be fine - but as the article says, you do get a lot more control if you print them yourself.

    Unfortunately, something like KDE is in a way part of that operating system itself - while porting, say, the rendering engine of Konqueror to Windows and giving it a Windows front-end could be useful, a full-scale port of Konqueror with all the KDE support libraries underneath would frequently involve reinventing and replacing wheels already present in Windows.

    Things like file selectors, the print subsystem, network abstraction and so on - while incredibly useful features for KDE to provide to its applications, they're generally available in different forms on other non-UNIX operating systems (and MacOS X). It makes more sense to integrate with the platform's existing facilities, giving the users a more consistent interface, rather than present them with a whole new interface for certain tasks.

Unlike Halo and Halo 2, where co-operative play online was apparently an insurmountable technical challenge, in Quake-based stuff even single-player games are inherently client-server anyway.

    From the article, it sounds like Halo 2 multiplayer has moved in that direction away from the all-clients-equal approach of Marathon and Doom, with a single server accepting or denying player-damaging events. Although each client apparently still has a full version of the game world at hand, unlike Quake-style games where a client is only sent relevant stuff - might this allow for some audacious, map-spanning ultra-vision hacks and so on?
