  1. Re:No on LED's Efficiency Exceeds 100% · · Score: 2

    Thank you for that, TFS made it look like they somehow managed to overcome the laws of thermodynamics. I was going to ask you to explain farther but RTFA instead.

    As the researchers explain in their study, the key to achieving a power conversion efficiency above 100%, i.e., âoeunity efficiency,â is to greatly decrease the applied voltage. According to their calculations, as the voltage is halved, the input power is decreased by a factor of 4, while the emitted light power scales linearly with voltage so that itâ(TM)s also only halved. In other words, an LEDâ(TM)s efficiency increases as its output power decreases. (The inverse of this relationship - that LED efficiency decreases as its output power increases - is one of the biggest hurdles in designing bright, efficient LED lights.)

    It seems to me that it's just fiddling with the numbers; it isn'r really ">100%", it's "better than 100% when compared to higher power levels."

    I did expect a better article from Psysorg. I'm still not completely clear on it, but it seems to have no practical value, only an academic excersize.

    But it's really not a big deal for the OS's interface to change - and it's expected. It's been going on for DECADES and for some reason people freak out every time it happens again.

    I don't know about Apples, but anyone going from Mandrake a decade ago to kubuntu today would find few changes, all of them improvements. Windows, otoh, is maddening in their insistance that the interface has to change drastically every release (and seemingly with no improvements in the UI), and imo it's simply brain dead stupid. It's one of the biggest things that drove me to Linux.

    I wouldn't expect Apple to pull anything so stupid, but I could be wrong. MS? I expect user-hostility from them. And canging the interface for the sake of change IS user-hostile.

    While *I* love new UIs and shiny things in general, there are lots of people out there who cannot abstract computers and are lost when small things change.

    Trademarks are indeed generally industry-specific indeed, think Apple Computer vs Apple Music as well-known example.

    I think a "menu" style application selection is bad. I can't count how many times I've bounced between different options 2 or 3 levels down and had to start over b/c my mouse moved a few pixels the wrong way.

    What infuriates me is that they stopped using "sticky" menus ten or more years ago. You want to open a file, click "file" and edit is open -- damn it, the file menu should STAY open until I make a selection or click outside the menu.

    It's a really shitty design that iinm MS started, and unfortunately KDE has emulated it.

    While not for the masses, I like dmenu_run tied to a hotkey. There's no mouse involved and just a couple of keystrokes always finds what I need. But that's a linux solution.

    It isn't a linux solution on my Linux box. It uses the TV as a monitor, with a wireless keyboard and mouse. The keyboard almost always sits on a shelf unless I need to enter a password or something. And you can use a keyboard in Windows, it's just that few do. Hell, you even have a command line in Windows if you want one.

    What REALLY annoys me is applications (in any OS, linux apps are often just as bad) that insist on mousing when the app's main functions need a keyboard. That's incredibly bad design from an ergonomic standpoint -- ever get "mouse elbow"? That comes from having to repeatedly go from keyboard and mouse to back, and is an unforgiveably bad design.

    I hope a few developers (esp linux devs) think about this when writing their naxt application.

    Mind you, there are caveats. Sample length has to be infinite.

    Exactly! Note that the closer you get to "infinite" the closer you get to "perfect". The higher the sampling rate, the closer to infinite and the closer to perfect.

    In any case, what I was trying to get at, is that sampling a sinusoidal waveform, even a 15kHz wave at a 44kHz sampling rate, reproduction is going to be very accurate. The mathematics show it. Certainly orders of magnitude more accurate than capturing a square or sawtooth.

    Yet there are more than sine waves in sound. A rock guitar fuzzbox changes the guitar's sine wave to a square or sawtooth (most fuzzboxes and wah wah pedals have a switch to select between square and sawtooth). With three samples (do the math!) it is impossible to discern those three entirely different waveforms. They will be distorted into a sine wave.

    Have you ever studied sound with an oscilloscope? One of my undergrad physics classes was about this very thing, although it was in the late '70s and there were no digital samples back then.

    Have you seen rock or blues bands with the guitar feeding into a small tube amp, with a mic in fron of it feeding a transistor amp? That's because if you overdrive a transistor amp to clipping levels, you get a perfectly square square wave, but with a tube amp the wave's corners are rounded (as seen in an oscilloscope) at clipping levels.

    It is mathematically impossible to do that with three samples.

    Besides, the practicality of listening to a cannon and soft flute, at their natural volume level, in the same piece, is rather bewildering.

    Those pieces are ancient, and are usually performed outdoors. You would have to have an incredibly good setup to get anywhere close to accuracy with those pieces.

    To deliver such an one unto Satan for the destruction of the flesh, that the spirit may be saved in the day of the Lord Jesus.

    Therefore let us keep the feast, not with old leaven, neither with the leaven of malice and wickedness; but with the unleavened bread of sincerity and truth.
    I wrote unto you in an epistle not to company with fornicators:
    Yet not altogether with the fornicators of this world, or with the covetous, or extortioners, or with idolaters; for then must ye needs go out of the world.
    But now I have written unto you not to keep company, if any man that is called a brother be a fornicator, or covetous, or an idolater, or a railer, or a drunkard, or an extortioner; with such an one no not to eat.
    For what have I to do to judge them also that are without? do not ye judge them that are within?
