    so I'm not sure why they should or could be ashamed of their lectures.

    Interesting point. I don't think professors in general are ashamed of their lectures; however, I can certainly imagine that bad notes will reflect bad on the professor - as the person reading the notes cannot know whether the lecture was bad, or the note taker.

    More likely, a better question would be, which you allude to is, what law or laws prevents them from distributing their notes?

    That depends on what kind of notes they are. If the notes for instance include parts of what a professor writes on a blackboard (or whiteboard), copyright laws.

    The interesting case are notes that do not contain any verbatim copies; whether copied from the blackboard, or what the professor is saying, but are purely describing the lecture of the professor. Who owns the copyright on that?

    I will now post this notice informing all journalists that I must be contacted first to be qouted outside of this Slashdot discussion.

    Irrelevant to this discussion. The (fair) use of quoting with respect to copyright laws has been established quite some time ago.

    you run into problems with the fact that the process of measurement affects the measurement

    Yes, and if I stand on a scale, that will influence my mass as well. That doesn't mean that the measurement is pointless. The conclusion of the Heisenburg principle isn't "all measurements are pointless". The conclusion is "there is a limit on what you can measure simultaneously".

    you run into problems of chaos theory and spontaneous order. The problem is that a small error in measurement can lead to an enourmous change in the outcome.

    Yes, and that's true for a lot of problems. But you can also calculate how much errors in your measurement influence the final result. Weather forecasting is a perfect example. There's a limit, but todays limit is further than yesterdays, due to the ability to use more data, and better precision. Nowadays, you see 5 day forecasts. I certainly remember the times you got only 3 days, and the forecast for the third day was much less detailed than you get nowadays for 5 days.

    For example, say Boeing wanted to design the Next Generation spaceship using genetic algorithms. They certainly could distribute the work for that type of application.

    They could, but I highly doubt it will be worthwhile for them. The big problem is trust. With RC5, and other cracking contests, trust isn't a major issue. A client saying "I found the key" is easily falsified. A client saying "Nope, the key isn't in this block", while the key is, is a problem, but you'll find out eventually; and you have to "just" retest the blocks. And with the assumption that the number of people not playing fair is low, chances that the winning key is given to an unfair person is low.

    But it is more of a problem where all the results are actually used. What if a malicious person starts feeding false results? Sometimes, it doesn't matter. The first large scale internet cooperated crack of a code was RSA-129 by Lenstra et al. That wasn't brute force, but used computing power to initially populate a huge, sparse matrix (it's been years ago, I might misremember some details). The final algorithm was robust enough to cope with some percentage of bogus data.

    But do you think Boeing will take that risk? Would *you* want to fly an airplane if it was designed using numbers returned by some random script kiddie?

    No. Sidestepping the fact that distributed processing doesn't form a limitless computer system (let's take the current RC5-64 contest; there are about 40,000 participants. Let's be pessimistic and say every participant only uses one computer. Let's also assume there are 1 billion computers in the world, 1 computer for every 6 people. That would mean you could do about 25000 contests simultanuously. With the current speed, it takes about 6 years to crack a single message, so, throw a lot more computers together than there are, and you're looking at cracking 4000 messages a year. That's far away from limitless...) sharing processing power isn't that easy.

    RC5-64, and other brute force cracking attempts are easy to do distributed. It takes the most trivial distributed setup (one master, and a bunch of slaves that all work indenpendently - all the master needs to do is bookkeeping, there's no other communication or synchronization needed). Many other problems aren't easily turned into a distributed equivalent. Other problems only work well in specialized distributed environments, parallel computers, where processors are synchronized and you know in advance when which processor is going to write where in memory. Simulations of fluid flows for instance.

    Some problems are impossible to solve. Take for instance the classical election problem. You have two identical processors, with identical software. Elect a leader.

    Even harder is the problem of how to split up arbitrary tasks in a distributed environment - and deciding which problems can be solved distributed, and which don't.

    Then of course, there are things like nodes and links going down, unknown latency, nodes that cannot be trusted, not knowing your topology, etc, etc. Distributed computing in general is a science - and not an easy one.

    Most certainly, Unix machines aren't magically protected against virusses. The best known example is Morris' worm in the late '80s. While classified as worm, there was nothing in particular that wouldn't make it a virus. Morris just had no intention to destroy things.

It won't do any harm, and it will only infect files ending in ".pl" in the current directory, but it will replicate - even if you just "compile" the code.

    There are a few reasons why virusses on Windows are more common than on Unix. First is the permission system. A windows user or process typically has access to all files, so it's much easier to do damage once you are running. On Unix, you either have to hack root, or you can only do "limited" damage (although quite severe for a user). Secondly, there are many more Windows machines out there then Unix machines - besides, Unix is a twisty little maze of incompatible systems anyway. Third, there are more applications that will execute code without the using being aware. Fourth, "sneakernet" with cracked binaries of dubious source is more common. It might take a bit more effort, it's certainly not impossible to write virusses for Unix.

    whatever would have to have the ability to obtain root privileges

    Unix has almost 30 years of history of security holes that give you root access. Ever heard of scriptkiddies with "root kits"?
