I disagree. Plenty of software in general, and some languages in particular suffer from the "too much design" disease. On the other hand, software which is being written well (for some definition of "well"), tends to outgrow the flaws in its initial versions even if at the end one can hardly recognize that this is the same software.
The classical example of an "overdesigned" language is Java (I am lousy at separating the language from its APIs). What you get is some more "reuse" at the price of unnecessarily complicated framework. With languages like PHP you learn the right way by mistake (which is not necessarily suboptimal) and you should have the guts to break compatibility from time to time.
As for being disgusted by PHP -- usually you don't get disgusted by the language but by what people have written in it (or around it - talking about some PHP extensions). One can always find examples of an extremely ugly LISP function with LISP being one of the most beautiful languages ever.
But I'm heading towards a treacherous field - discussing programming language merits - wasn't it "the best tool for the appropriate job"? So, let's keep PHP for all these "gee whiz" tasks which apparently the society needs, otherwise go explain the x millions of PHP-sites...
At the end we will all grow software like plants:)

Since when is language design a grad. discipline? The Zend guys happen to be damn good programmers - have a look at the code of the interpreter.
We are doing something similar -- it is Prop. -> CNF -> DNF, and then scan the resulting DNF table for all matching terms which are also diagnoses if they are not consistent with the observation. The problem is that these dictionaries grow very fast if you are not extremely careful to create an over-constrained model. At certain point you have to sacrifice completeness and start considering fault probabilities. What you've ported (NNF) was (is) quite high in my wish list to implement and to compare (in practice) with the DNF approach, but other priorities:(
A while ago I received the Livingston packages but the models are in very weird format or at least I didn't find what I was looking for... Just curiosity how far ahead (in model size/precision) is the rest of the world...
DNNF for diagnois - that's Adnan Darwiche. What was the biggest number of components you could diagnose in reasonable(?) time? If you could compile your model I reckon that you used strong fault models? What was this project, BTW?
I have about 25 'old' laptops, stacked in a few piles, in the corner of my office... They ARE my Beowulf cluster
That's interesting. What kind of computations are you running there? The whole setup sounds like bloody heterogeneous (probably you have all different network, CPU speeds, memory sizes). My feeling is that besides for some pretty coarse-grained parallel jobs it is not good for anything else.
Interesting, I don't believe that mandatory voting is compatible with a modern democracy.
AFAIK, there is always a blank ballot if you don't want to support a particular candidate.
I'm not sure mandatory voting is incompatible with modern democracy... One of the ideas is that the democracy should preserve itself, and non-voting can be treated as a welcome sign for non-democratic governances.
If the challenger were someone like Ahnold, though, it would be a different story...so I predict that Greece's politics is full of career politicians and movie stars.:)
Heh, we should learn to respect the terminator... In Italy they choseChicholina (a porn-star) for an MP. In Argentina a singer, was elected as vice-president and even today she is celebrated as a national hero, although she greatly helped to ruin a thriving economy.
In Bulgaria the hoi polloi vote, with an overwhelming majority, for a maverick ex-king, sworn in the republican constitution, just because he promised the people unthinkable wealth in half term...
With high-speed interconnects (i.e. infiniband/myrinet), it is very feasible.
Hm, I haven't played with infiniband, but I have access to a small Myrinet cluster and it takes hell lot of efforts to write your application in such a way as to overcome the big disparity CPU power/network thoroughput and to have some normal speed-up.
Paul Terry is right - if they remove the PCI bottleneck it will be much easier to write scalable high-performance applications and then the costs will decrease.
Well, if the symbols are close enough because they use the same color, then anyone who produces an orange logo is going to be prosecuted, right? If only the happy trademark owner can use the color, isn't that equivalent to a color monopoly?
Your formulation is correct but, IMO, a lousy interpretation of the article allows someone to say that the companies are fighting for the right to own the color. The author of the article did the same "mistake" when choosing a title for his article...
...no one can own a particular frequency of spectrum in the same way no one can own a particular color of light...
Wrong. At least some big corporations would disagree with this statement. As a matter of fact we (figuratively) pay taxes to educate business people who dispute who actually owns a color...
It won't be long before hardware is essentially free, and the software/services you buy are where the money is generated.
Wrong, comrade. Not only hardware will be free, but software will be GNU. Toothbrushes and women will be public property and we will be living in the communism!
Steganography. Hide your message in an image posted to alt.binaries.pictures.erotica. The feds might be able to figure out that a message was sent, but they won't have a clue who the recipient was.
Steganoanalysis. If I am a fed and I suspect you I would tap all your communication. Then I would give it to a whole class of kids to analyze it at leisure. They will discover all kind of patterns which you may have intended to create or not. You know - humans are pretty good in seeing patterns. Programs, not so, but they are improving.
And if it turns out that you are doing something illegal and you are using steganography and/or cryptography the latter should aggravate the offence (i.e. you shoud in addition of being punished also pay the efforts to detect communication/decipher the data)?

However, the Earth Simulator deals with chaotic systems (or so I would assume), which do not independently parallelize; this is where having hundreds of processors and terabytes of RAM and using something like NUMA is greatly more efficient.
AFAU Earth Simulator solves mostly nothing more than a big Finite Element Method problems. Speed-up of such problems depends much on the connection time as normally the FEM solver exchange borders every several iterations or so, while the amount of data is not so much (hence no bandwidth utilization). Now with global distributed computing projects this is a problem as if my neighbours are distributed non-unformly around the globe, I have to wait for the last one to return border data so I can continue with the computation...

In Greece the voting is mandatory. The one who doesn't fulfill her social obligation to be responsible is fined. Greece is the oldest democracy.
