    And the GNU GPL forbids the addition of extra restrictions. ... Do you see the problem yet?
    No, I don't. You could distribute the program strictly under the GPL, and not put in any such restriction. The fact that the EU passed laws making it illegal to modify the code to take out the currency blocker is not a restriction imposed by those distributing the code. I do not see how a GIMP developer, even in the EU, is in violation of the GPL by distributing a program that is further restricted by EU law.

    Caveat: depending on how the EU law is written, such an EU GIMP developer may well be in violation of the EU law, e.g. if the law prohibits distributing enabling technology, the way the DMCA does in America for copy-prevention-breaking software. EUphies should check that before releasing GIMP or similar patches.

    Caveat2: IANAL, nor am I EU, so do your own legal advising.

    No, that was OS/9, which was an alternate OS for the Radio Shack Color Computer II, a completely different product line than the TRS-80. The TRS-80 had:
    • full keyboard
    • came with a BW monitor
    • used a Z80 CPU
    while the Color Computer II had:
    • chicklet keyboard
    • a modulator to interface to a color TV
    • used a 6809 CPU
    To make it a really useful OS/9 machine, one would skip the color TV and the chicklet keyboard, and instead snarf an old serial terminal and plug it in the serial port in the back and log in.

    The CoCo II was my (counts on fingers and toes) 4th computer. A shell prompt and multi-user OS in 64KB on an 8-bit CPU was damned impressive back in 1986.

    My credentials:

    Canadian born and educated

    moved to the US 10 years ago after finishing my PhD

    worked in the US and Canada as a developer/intern, and in the US as a professor and executive

    Bias: as a child, I was always an American-wanna-be My opinion: Canada and the US are very similar: It is wisely said that Canadians are polite, unarmed Americans, with health care. However, there are interesting differences:

    • Canadians are more "conservative", in the small-c sense of danger-aversion. Canadians by and large will accept an average lower standard of living in exchange for a lower risk of catastrophe. This shows up in substantially lower wages for technical staff, but with a substantially higher standard of living for those supported by the social safety net.
    • There is much less entreprenure-ship in Canada. Go to Canada if you like large companies, because there are a lot fewer start-ups.
    • Republican bullshit not withstanding, the Canadian single-payer health care system works better than anything I have ever seen in the US.
    • Canadians are generally more reasonable and less excitable than Americans. Conversely, Canadians are a lot less exciting than Americans. A Canadian radio station once ran a contest to pick a saying analogous to "As American as apple pie." The winner was "As Canadian as possible, under the circumstances."
    A lot of Canadians have a very poor opinion of the quality of life in the US. I submit that this is because a substantial plurality of Canadians actually live in Southern Ontario, between Buffalo and Detroit. If all you ever heard of the US was that North Tonowanda was burning again, what would you think? :)

  7. Re:Uh Huh on Anti-Missile Laser Weapon Successfully Tested · · Score: 1
    The only way yoru going to take out a THEL with a reflective coating is if you had the mirror perfectly perpendicular to the bear.
    No, that is just not true. There are at least two easy ways to construct mirrors that send light back from where it came, regardless of the angle of incidence. One is spheres with a refractive index of 2.0, and the other is right-angle mirrors. The former is used in bicycle reflective strips, and the latter was used on moon missions to deposit 2 foot devices on the moon that would conveniently bounce laser beams back to earth for handy measurements, without having to precisely aim a mirror at the earth. Absolutely no perpendicularity required.

    Caveat: except for efficiency. These bounce-back mechanisms both involve reflecting the laser beam twice before returning it. That doubles the amount of energy the missle absorbs, but it is still absorbing a lot less than it is sending back to the cannon.

    Hmmm. Ok, so high quality reflective material in the infrared range is hard. Sounds like a technology problem. It leads to an arms race:

    • On one hand, we have some guys trying to make durable, high-quality reflective material that can sustain high load in grubby battle conditions. The reflection does not have to be very precise, just "go somewhere else" will do.
    • On the other hand, we have some guys trying to make laser cannon. This involves near-perfect mirrors that have to survive battle conditions. The cannon has to handle power loads of 10X to 100X at least vs. the reflection guys. The cannon has to precisely target a distant, small, high-velocity projectile. The cannon also has to power through various weather conditions, clouds of smoke, etc.
    Who's job is tougher?

    I don't say the cannon cannot be built, or even that it won't work against missles that don't have a defense, but I do think the advantage is with the missle guys.

  9. Re:Uh Huh on Anti-Missile Laser Weapon Successfully Tested · · Score: 4, Interesting
    Are you claiming that it is somehow difficult to make material that is highly reflective in the infrared range?

    I suggested bicycle strips because they have a fascinating property. They are made of zillions of little sphericle beads, with a refractive index of approximately 2.0. Such beads have the interesting property that light shining into them is reflected back directly at the source. For amusement, go get a laser pointer and point it at some bicycle strips, and you will notice that your hand holding the laser pointer is painted with laser light, regardless of the angle you hit the strip from.

    So if I want to beat laser missle defenses, I go into the lab and make milspec beads with a refractive index of 2.0 in the right infrared range, and the lasers suddenly don't work so well.

    Bonus: make the reflective layer 1 inch thick, and make it boil when heated, and you get ablative armor: it fogs the missle with a clound that blocks the laser. IIRC, idea due to Charles Sheffield (RIP).

    I think academic CS is majorly wrong in this regard. "System administration" is the residual work that is left over after you have abstracted all the easy stuff. Lather, rinse, repeat for 40 years, and system administration of very large & complex systems is highly distilled complexity and difficulty.

    Another poster pointed out the irony in my devaluing degrees but valuing these certifications. All I can say is I can think of at least 5 honours degree holders that wouldnt have even come close to passing these certs without serious study.
    This mostly tells me that you do not understand the value of a (good) degree. Degrees teach concepts (software engineering, concurrency, relational databases) while certificates teach particular technologies(Visual Studio, particular thread libraries, Oracle). I will take someone trained in the concepts over someone trained in the technologies any day.

    Technologies come and go, and picking up a new one is just a matter of reading the manual. Concepts require hard-core education, and someone trained only in technologies often falls flat as soon as the technology falls out of vogue. Consider: how would you value someone with a resume that said they were familiar with Borland, DBase IV, and HTML?

    Caveat: I am not saying that people who don't have degrees don't understand concepts. Rather, that the certificates focus on technology trivia, and thereofre you cannot tell whether the candidate knows the concepts or not.

    I have met some astoundingly brilliant letterless people. I disagree that a majority of outstanding developers are degreeless, but they certainly are a big chunk.

    I do however, take slight issue with your point about certificates. I have found some of these to be very worthwhile. I have certificates from Sun in their Java programmer, Java developer and Java web component developer qualifications and found them (particually the programmer) to be an excellent base-line skill test.
    While have occasionally found people with certificates to be quite good (some of my best friends are CISSP's :-) I have never found any significant correlation from certificates to skills. If anything, there is an anti-correlation: those holding (more importantly, advertising) "certificates" have a slightly elevated probability of being useless posers who are good at test taking, and little else. I put the certificates at the bottom of the resume pile, and the actual/relevant skills at the top.

    I have recommended to my current employer that all developers working on our software should either have the programmer certificate or be working towards it.
    I find that highly disturbing, and would not tolerate such a policy. Why should someone who is highly competent, productive, and well-read in the subject be forced to be "working on" a certificate that does nothing but expensively validate skills you already know are present? I value real degrees because they tend to deliver education. I devalue "certificates", because they tend to be light on the education and heavy on the testing.

    And what would be the basis for this bogus guess of yours? My point in placing the disclaimer was precisely that we hire on performance instead of credentials. More particularly, a real degree from a serious school is an achievement, just as substantive work experience is an achievement, and I don't distinguish.

    "Certificates", on the other hand, are largely crap that serve only to identify people who do broad/shallow test-taking well and can afford to pay the fees. "Certified" people may or may not also be competent, but the certificate tells me little about their skills.
