  1. Re:Very original idea on Optical Concentrator To Make Solar Power Cheaper · · Score: 1

    Amplifying light with a glass 'optic' would be quite original.

    Optical fibre amplifiers use a length of erbium-doped glass as the amplification medium. They were invented in the 80s and are used around the world. An external source excites the erbium and as the signal to be amplified comes in it stimulates emission. The result is a signal coming out brighter than the one that went in.

    http://en.wikipedia.org/wiki/Optical_amplifier

    Of course, it'd be daft to use one in this application as while they do amplify, it's not like they're >100% efficient.

    Quite simply, it's immoral to leave future generations the obligation to take care of a problem, both physically and financially, that we generate today.

    If you ignore the mindless Greenpeace types, and your power is from nukes (like in France) there are no greenhouse gas emissions at all and the air stays nice and clean.

    Greenpeace are a bunch of nutjobs and the more base generation goes nuclear the better, but it's not totally greenhouse-gas-emission free. Mining the ore and enriching it generates GHG. The many, many tonnes of concrete that go into building the plants (~200 cubic metres per MW) generate GHG. Sure, it's the total GHG/kWh is less than just about any other technology, but it's not nothing.

  5. Re:flicker crashes on New York City Street Lights To Go LED · · Score: 1

    Assuming the line voltage is run through a full wave bridge rectifier, there would be a 120 Hz flicker, imperceptible to most people. Toss a large capacitor across that DC output and you've got dramatically less ripple.

    I certainly hope they're a wee bit more complicated than that. Can you imagine the power factor problem we'd have if we replaced all streetlights with LED ones that just use a bridge and large capacitor?

    Electrolytic capacitors are one obvious place cost can be cut.

    There are a couple of topologies that are applicable. Most computer powersuuplies are (I think) single-switch forward converters. The topologies with more switches provide better performance, but more switches means more expensive transistors.

    Higher frequency switching generally provides more stable output, but requires "faster" transistors and transistor drivers, which again, are more expensive than "slower" ones.

    We had forgotten how much of irresponsible populists the Labor party are.

    If Little Johnny is to be remembered for anything it was his ability to sniff and exploit popular opinion. He was a canny bastard and that's why he lasted as long as he did.

    Australia went Labor because we hate politicians and we get eventually sick of whatever party is in charge and vote in the other guys. The two parties are so similar that the issues at each election are just window-dressing.

    Now we have that idiot Rudd spending education dollars on free laptops, telecommunications infrastructure dollars on censorship and tax dollars on allowances to buy Christmas presents. I can't believe that I voted for these arsehats.

    The coalition also spent millions on internet censorship, the "technical colleges programme" and a range of allowances like the baby bonus.

  11. Re:Streisand effect on Aussie Censorship "Live Trials" Won't Be Live · · Score: 2, Interesting

    If you want to censor something, having a list of censored things only makes people more curious. It's much better (for the censors) to keep the censored list secret.

    This reminds me of the anecdote of the old lady who went to compliment Samuel Johnson for not putting any "bad words" on his dictionary.

    -- "Why, did you look up all of them"? was the answer.

    That doesn't quite follow because the list isn't the actual content being censored, but the addresses to the content. I can view the list and be satisfied (or not) that it's not being used for political censorship without actually viewing any illegal content - or, I could if it weren't a crime as it currently is.

    The problem is that in most democratic countries on many issues do not have a choice since the two (or three at most) major parties agree and so whoever you vote for nothing will change

    The recent US elections are a case in point -

    That's because the US federal election system is a first-past-the-post system, which is deeply flawed in this way. The Australian system uses preferential voting, meaning a vote for a minor or single-issue party (Like the newly-formed Australian Sex Party which opposes this censorship as a core platform issue) is not a wasted vote.

    One of the important goals of protesting is to get many people to take notice of the issue who otherwise wouldn't. If nobody pays attention to the issue it's not going to affect how they vote.

    Boing Boing deleted any and all mention of Violet Blue for reasons that remain unexplained but are assumed to be a lovers' spat. When people found out that Boing Boing had retroactively censored one of their contributors they felt that this was hypocritical given the editorial content of the site. Boing Boing tried to diffuse the situation by posting a non-explanation calling their actions "unplublishing". The term as used is an ironically Orwellian neologism for censorship, deepening the public outcry that the actions of Boing Boing editors were being childish and deeply hypocritical.

    He's a wise choice, a rational voice is a sea of stupidity.

    Lessig is a very moderate voice. While he generally opposes copyright term extension, he supports DRM. He feels that people who say copyright law is utterly broken are extremist. He seems to think that the current scope of fair use provisions is adequate and just needs to be better respected. He feels that "something like the DMCA that protects adequate space for fair use and doesn't attempt to regulate technology directly is needed." (http://lwn.net/2001/features/LawrenceLessig.php3)

    I have a lot of respect for the man but you can't meet the extremism of Big Media with moderates willing to compromise. The DMCA should be dumped and language written into the law the specifically protects reverse engineering. Fair use provisions should be expanded to reflect that way we use media in our lives and to provide better protection for educational use.

    We don't need a moderate - we need somebody who will make dramatic changes to re-align the law with common sense.

    I call bullshit.

    As I recently heard Lessig point out, the US government is less popular with its constituents these days than it was preceding the American revolution. Your economy is circling the drain. You have massive and growing separation of the rich and poor. You've had almost a decade of politicians shitting on your rights and your founding principles.

    The time for you to mobilise your well-regulated militia was long ago. And you know what happened? Nothing.

    It's about time you stopped being so naïve. It's clear the governments of developed and developing nations have no greater fear of a population of gun nuts than of flower-wielding hippies. Neither community will sacrifice their bread and circuses so long as they can vote for a new guy in the next election. Fair and transparent democracy is the best and most natural defence of a free nation, not the possibility of slaughtering a stack of your fellow countrymen in the name of revolution. All that gets you is the sort of political stability we see in Niger and Darfur.

When I called to ask about how to get it working again, Wolfram told me that my only option was to buy a new copy of Mathematica.

    I couldn't agree with this more - I bought a copy of Mathematica in 2003 and every time I upgraded the OS or even installed the same OS on a new machine I had to ring the US to try to plead a new licence. The process was such a damn pain I downloaded a cracked version and used that instead, and it worked flawlessly until I moved to Octave and Maple a few years later.

    The whole user interface is a collection of abstractions. How the program stores its data should be largely irrelevant to the user's interaction with her stuff. A photograph on my system is a presentation of a particular set of bits on my harddrive just as a Word document is a presentation of another particular set of bits on my harddrive. They are both abstractions.

    If I accept your distinction that applications that deal with databases quit upon closing their main window and applications that deal with files don't then Safari doesn't fit.
