New Jet Engine Tested

SpaceAdmiral writes "A revolutionary new jet engine has recently been tested in Australia. It is hoped that the engine, designed by UK defense firm QinetiQ and capable of Mach 7.6, will pave the way for ultra fast, intercontinental air travel. Scramjet (supersonic combustion ramjet) engines have no moving parts and take all of the oxygen they need (to burn hydrogen fuel) from the air, allowing for larger loads than rockets which must carry oxygen for fuel."

      The higher the technology, the sharper that two-edged sword.

    IIRC, Australia's Qantas Airways was until very recently the only major airline without a crash. So, either they are good at what they do, or Australia's not a popular tourist attraction.

    It is remarkable how similar the intended future use for scramjet technology is to that described in a Philip K Dick novel by the name of Man in the High Castle, namely passenger airliners and space travel. The extremely fast ascent, followed by a relatively brief period in the lower stratosphere, and finally another period of intense speed, this time descending towards the relevant destination. Of course, in the novel the "Rocket ships" described are probably intended as an evolution of the V1/V2 bombs used in World War 2, a technology very different from scramjets - and completely neglectful of the potentially massive chemical costs per launch far outweighing even the most ostentatious of passenger fares :) . But even so, the similarity in timeframe description and such is remarkable considering the V2 was little more than a predecessor to the SCUD missile, and that scramjet tech was unheard of at the time of writing (1962).

    He wasn't the first of course, H.G. Wells predicted something resembling an atomic bomb, together with tanks during Edwardian times. It would be interesting to examine trends in developing technology, to see whether the cause and effect correlation with sci fiction predictions is beyond the aesthetic. We can already observe that many aesthetic features of say, some of Star Trek's technology, has made its way into the modern technology of today. Eg. The flip communicators -> mobile phones etc. It is a testament to the human imagination that much of the technology posited in past fiction is coming to fruition today.

    Yea, my favorite missle weapon was a magic +3 sling of speed that my halfling warrior used to specialize in. Roll d20 to hit! To Arms! To Arms!

    Checking lots of individual words for matches in recent articles is probably a little DB intensive, but the editor-only code areas that this would be in are quite low traffic.

    I can't think of any obvious ways, on the spot, to implement it, but given such low traffic, might it not be possible to check every single word in the article-in-progress, and use the power of statistics to determine whether it's likely to be a dupe?

    I mean literally getting a few dozen of the most recent articles* and strpos'ing every word, or you could do some of that funky SQL stuff, you know - of $WORD in $ARTICLE get $THEM and make $MYTEA soon while check for $DUPE.

    If stats alone can't hack it, then return a finished "% Match" figure to the editor, which he can use to guage the likelihood of it being a dupe. Pass him the articles with the most matches so he can check it instantly.

    IMPORTANT DISCLAIMER: I don't give a shit about dupes themselves. I really don't. I just see them as an interesting technical challenge that we should be able to overcome, wait, scratch that, that we should be itching to overcome.

    * [if even that's too intensive, then have a seperate area where a fixed number of recent articles are pushed through so that you can just check a nice quiet static block of crap instead of doing actual DB queries]
