    Tolkien also published an essay on Beowulf entitled "The Monsters and the Critics", which I have not read, but have heard is excellent and was the cause of an academic reappraisal of Beowulf.

    Yes, I found it in an old book sitting in a box at home a few years back, it was quite good. I had just read Beowulf for a class and figured that Tolkien might give me some insight for any papers I had to write about it. ;)

    On a nit picky note about your otherwise informative posting, the "255 per second" in the article you quote should actually have been "2 to the power of 55"

    Oops. I was just going off what the original post said. I thought it was weird that they were says 255 keys/second - I mean, a 100 Mhz Pentium could do that!

  4. Re:149 trillion years? and it's not good enough fo on AES Announced as Federal Standard · · Score: 1

    US Government classified information? What the heck are they using for classified info crypto?

    Short answer: Stuff designed and vetted by the NSA.

    Also note that 149 trillion years is an upper bound on the strength, and 255 keys/second is pretty damned slow. Brute force is essentially infinitely parrelizable; consider a room with 1,000,000 FCPGAs or ASICs each cracking 100,000 keys/second. That's still about 53914487622781590403 years for a brute force (on average), but you catch my drift, I hope.

    The algorithm itself also has to be strong. It would not take much effort to design a block cipher with similar parameters (block size, key lengths, etc), that was trivially breakable. Rijndael is not trivially breakable, but it may (in fact, almost certainly does) have undiscovered weaknesses.

    Longer answer:

    There are a few major reasons the AES was not simply handed to us, fully formed from the head of the NSA.

    One is that they probably don't want to give people any "hints" about design techniques. We've learned a hell of a lot from trying to attack DES, and people have probably re-invented a good portion of the techniques the NSA had at the time. Getting the specifications to a block cipher designed with the NSA's latest design and analysis techniques would probably advance the state of the art by at least 5 years.

    Slightly off the topic: Some people at IBM claim DES was invented entirely at IBM, NSA had nothing to do with the design, and so on and so forth. I don't believe this is the case, but whatever. If you believe it is true, S/NSA/NSA+IBM in the above.

    Also, people were worried that the NSA would try to put a backdoor in it, or at least, people were worried that other people would worry that the NSA would try to backdoor it. So they wanted people in the academic community to come up with something for them. But obviously the NSA can't trust something like that, at least without a few years of "in house" analysis.

  5. Re:Completely untrue...! on AES Announced as Federal Standard · · Score: 1

    Now the minimal recommended key size is 400 bits longer, amd most of us use keys 900 bits longer.

    Actually, 400 + 100 == 500 bits, and a 512 bit RSA modulus was factored, um, either last year or the year before, I can't remember which. It took about 6 months with an array of about 400 Pentium IIs and Alphas, and one very big Cray, to do some precomputation and the final big set of matrix operations. IIRC, it used a modified version of the Number Field Sieve, which involved a good deal more precomputation, which for larger keys saves more time than it hurts.

    Many new specifications (for example, OpenPGP) specify an absolute minimum of 768 bits.

    ...and the books were quite clear that there was water on Arrakis at one point. It's a major plot point, really.


    Yes, I know. And there were big caverns of it underwater, hoarded by the Fremen. And later, under the rule of the God Emperor, Arrakis has water on the ground yet again.

    But I don't think any of those things would help you out much out in the middle of the deserts there.

    Why has no one asked why the poster feels the need for a still-suit? I believe even the harshest desert conditions on Earth don't really require one...

    Agreed there, but it does have some potentially useful applications. For example, military activity in a large desert; if you don't need to send in water, you spend less on transport, it's easier to carry everything, etc. Also I imagine there are some potential applications in space, though since the system is closed it should be fairly easy to recycle everything without waste anyway.

    But I agree, the situation that inspired the still suit (a planet almost entirely devoid of free water) exists nowhere on earth. Any place resembling such (Sahara is the only one that comes close that I can think of), basically nobody lives in anyway, so it's kind of a moot point.

    This isn't really that huge of a deal--idolizing a person because they aren't actually real.

    Japan-related but not Japan-specific: I and quite a few people I know are really into various anime characters. Yeah, it's fairly geek-oriented, I suppose, but it's not an exclusive club. And certainly they're not photo-realistic (but with good voice actors, animation, and writers, they can seem quite real, in a human sense).

    Not just the hot girls either (though there is a long list of anime girls I find pretty niz), but the cool heros like Spike Spiegel, Goku, and about N others. I know people who try to emulate these character's habits (not to a totally weird extreme, just little things).

    A little side note that won't make sense unless you've seen Cowboy Bebop: I was walking to a diner with two friends of mine, and walking the other direction was a woman walking a Welsh Corgi. In unison, we yelled in happiness: "Ein!"

    Unless that woman was an anime fan, she's probably wondering why people will say that when she's walking her dog around.

Maybe even a little bit of a price drop too, though as a poor-as-hell student I find the $100 reduction in price in the GC compared Xbox or PS2 quite compelling, though I wouldn't buy any of them if not for those certain Nintendo games.

    2) Related thing: BIOS updates and tweaking can sometimes go a long way.

    3) Upgrade the machine to the latest distro; a nice thing about Unix is things usually get faster, not slower.

    4) Figure out what is using your CPU time. For example, given you're running SPOP, I suspect a lot of that time is used for SSL. So recompile OpenSSL with better optimizations (the normal OpenSSL RPMs are always underpowered; asm is disabled, no -march flags, etc), and you should see a magical increase in performance.

    5) Assuming this makes your system faster, celebrate by spending some of the money you would have used to upgrade on beer.

    $1000 a month for a personal net connection seems really crazy, at least to me.

The Gang of Four (as the authors are usually refered to because nobody can ever remember all their names :P) did one or two other books on a simliar line ("More Design Patterns", I think?).

    Since you didn't say what kind of language you're going to use, and you mention the only stuff there is C and Matlab, I'll throw out some languages suggestions as well:

    It kind of depends on the experiences of the people you're teaching. If they already know C, C++, or Java, maybe doing the course in C++ or Java is the way to go. However, they may have too many preconcieved notions in those languages (like old C programmers moving to C++, and basically still writing C, ignoring the OO stuff when they can) to be effective object oriented programmers in those languages without some other experience.

    So you may want to look into something like Python. I can't think of any other major OO scripting languages (Perl doesn't really count too much), and ML/O'Caml/Lisp/Scheme aren't really OO langauges in that sense.

    Oh, maybe Smalltalk would work I don't know of any free implementations, hopefully there is in fact at least one good one. Objective-C is C plus Smalltalk-style OO and as it's built into GCC, it would be available for everyone, so that might be another option.
