    Great to see it gets some hard proof! ..or DO each of us drive 400hp cars? No? Why not? If we can't live without 2.8GHz, why should we "punish" ourselves with cars below 100hp?

    Well I bought a 350hp car because I didn't see that it was worth waiting a year on the waiting list to be able to buy the supercharged version.

    However I do notice that many of my neighbors have cars with equivalent capacity (4 litre or above) but give only half the power and less than half the mpg.

    I just upgraded my son's computer with the cheapest components I could get from Frys that I could be confident would last a couple of years (having previously bought grotty PCs and regretted same). For $350 I got an Intel motherboard, 1.9 GHz processor, 1/4 gig Ram and a pretty nifty video card.

    I agree that there is not much reason to upgrade from need these days. Even gaming is no longer a power users issue since the copy of tombraider angel of mercy you buy in the store next week will have been developed on hardware that is already close to obsolete.

    The only mass market, power application I see about at the moment is digital video editing. That will pretty much soak up cycles on anything you throw at it. But the market is fairly specialist still.

    As the hardware gets cheaper I am much happier to accept machines with everything integrated on the motherboard.

    Isn't it funny how the call for "open standards" always translates into "our version doesn't have half the features, so let's compete on what we have in common"?

    If the standard is a communications standard the lowest common denominator usually determines the features that are useful.

    Document formats only became a communications issue when we started to use email attachments.

    The original idea of HTML was that it could have become a common interchange format. However the lack of interest in developing page layout markup at Netscape kinda ended that.

    The problem with 'open standards' is that the standards organizations favored by open source folk tend to be the ones which move at the most glacial speed. Take IETF for example, it is quite usual for groups to take five to ten years. Simple changes can take three years to get implemented even when they are absolutely essential if deployment is to be possible at all.

    Unfortunately this thread does not appear to be talking about the AES issue at all, but garbled understanding of what quantum crypto can do.

    According to the cryptographer's panel at RSA quantum computing is much less of a threat than many assume. In the first place quantum computing tends not to be effective against symetric algorithms. Secondly RSA turns out to be based on a problem that is very very hard with conventional computing and very very easy with quantum computing. It is not clear that all possible public key algorithms are susceptable to attack using quantum techniques.

    In other words don't get the idea that quantum computing immediately means the end of cryptography.

    On the actual topic of AES I would not call this a 'break', in fact nothing less than breaking the cipher for real should count as a break. There are plenty of 'breaks' of DES but none of them are easier than brute force when applied in practice. What we have is a theoretical compromise that is way outside the capabilities of any current technology.

    Or consider it this way, given the known problems with 3DES (limited block size, severe limitation on safe amount of ciphertext generation) I don't feel like sticking with 3DES as a result of the article.

The point is that the C++ looks_crappy::structure.somtehing->pointer.somethi ng->pointeragain notation uses three different notations where one will serve much better and moreover combines prefix and postfix notation in an incomprehensible fashion.

    As for exceptions, the understanding of exception handling in 1980 was way, way to thin to build them into a language and certainly nobody had a rigorous semantic model for them. Combining exceptions with concurrency was a recipie for disaster in 1980 as neither was understood.

    As for the 'success' of ADA, what little success it has had has almost without exception been coerced. It does not say anything for the suitability of ADA for safety critical systems that it is used when the original proponents of ADA require its use as a contract condition. I don't believe that Boeing, Lockeheed etc. would ever have written a line of ADA had the USGovt not stated it would be a future contract requirement.

    Should any company require a university to teach a particular topic?

    I don't like mandatory non-core classes. If someone is going to a university to learn eletronic engineering there is no reason to require them to do an arts module, learn a language or any other crap.

    On the other hand I think that it is perfectly reasonable to require engineering and science students to understand programming and to require all students to take mathematics and philosophy.

    If I was taking an intro to programming course I would choose C# for a number of reasons. First like Java and pascal it is reasonably well structured and encourages students to start writing good programs. There will be plenty of time for the students to learn how to program badly using FORTRAN, COBOL, C etc.

    Second unlike pascal, C# is not crippled by braindamaged design. The pascal type system and one pass design is not something I would want to have to defend.

    Third, I would want to use a language that supports metadata and has some nice examples of its use - the XML serialization class is a nice example of what programmer defined metadata can do - and yes before folk who know Java but not C# chime in, no the Java support for metadata is not a substitute.

    Now metadata etc. is not the type of thing that is normally taught in an intro class, however my experience is that no compulsory intro class is all novices and I don't see why a course has to be a no-op for the most able students.

    C++ has a weak type system? C++? You may say whatever you want about C++ (complex, full of C pitfalls, a hell to debug, whatever) but "weak type system"?

    Actually C++ and pretty much every language out there conflates representation with type. From the point of view of Russell's typed set theory there is no particular problem adding an integer to a real number, however there is a big problem adding yards to volts.

    I can't say much about the C++ type system since I abandoned the language as garbage back in '92. Hoare's comment on Algo 60 vs 68 came to mind. However since C++ retains the void type and the whole C baggage it is difficult to see how it can have a strong type system.

    It is a pity that the catastrophe of ADA brought down the idea of dimensional analysis with it. Of course Hoare's Turing award lecture (please don't use this for anything safety critical the compilers are certain to be full of bugs) gave a salutary warning on unbounded complexity. But I thing dimensional analysis could have been retrieved from the wreckage since it has no run-time impact.

    There is a considerably more likely story that predates the 'cooked' story by several years, I heard it in the 1980s. I strongly suspect that the cooked story is simply the result of successive embelishment.

Afterwards some of the men started to complain about eye problems and it appeared that the radiation had damaged their eyesight by slightly cooking their eyeball.

    This is actually quite believable since it does not take that much to dislodge gunk from the retina, iris etc causing it to float in the aqueous humour and disrupt vision. It can be caused by drinking too much strong coffee - as I discovered during my 2nd year exams.
