Re:Nonsene.
Have you seen this site,
http://bruscy.republika.pl/pages/przemek/java_not_really_faster_than_cpp.html
This guy made a few tweaks to the C++ code (and documents them) and finds that C++ is about 2 - 3 times as fast as Java.

Re:There's a bigger problem that needs addressing
Actually it is not just a semantic issue. The Moon is massive enough to significantly shift the Earth's orbit around the Sun: the center of the Earth-Moon system (the baricenter) follows a Kepler elipse, but the center of the Earth itself is up to 2,500 miles outside this elipse every New Moon, and up to 2,500 miles inside this elipse every Full Moon.
So from Full Moon to New Moon, the mass of the Earth is shifted a total of 5,000 miles, and in month's time, the shift is 10,000 miles. Shifting the earth's tonnage at an average speed of 14 mph is sort of a big deal. Suppose an observer in a nearby star system was able to see the Earth in his telescope, but not the Moon for some reason (maybe he's tuned in on water vapor): he would still be able to recognize that the Earth had to have a massive companion, and he would be able to figure out the Moon's size and orbit just from the Earth's wobble.
So even by celestial mechanics, the Earth - Moon pair should be regarded as a double planet.

One of the many things you may need to do is...
You may need to start by converting your iso-8859-1 or other European ASCII to UTF-8 or another sensible Unicode charset. Some of our MySQL data was in the dreaded windows-1252 encoding, and I had to convert it to UTF. I downloaded the Convert Charset class (found via http://phpclasses.org/ from Mikoaj Jdrzejak, and with that I discovered I could basically convert anything I wanted from whatever charset to whichever charset I like. Wrote a couple scripts, and that was that.

Not new...I've been doing this forever. I run Linux on my main machine, but use my old Win98 laptop with the Winamp plugin to send my stuff to my iPod. Don't have time to mess around with the iPod in Linux right now (hhaha but ironically, i have time to check slashdot today).
Here's the Win98 iPod USB driver that I use to get it to talk to the Winamp plugin.

Re:significant error with video hardware
True, to a point. By 1984, PCs were already shipping with more than 1MB of memory, although the base model of the newly-introduced IBM AT was only 256K
The Commodore 64 was woefully obsolete by then -- a 1978-era PC technology sold dirt cheap.
Either way, if you went back and looked at the Mac reviews from 1984, every one of them would have mentioned the anemic memory. IIRC, the "Fat Mac" followed on fairly quickly. -
Re:A moon?
The Hill sphere for the moon is around 60000km so it is possible, but I think in our solarsystem there is no moon known with a moon (don't know about the asteroid belt)

Re:Useful genetic modifications...
Try this kind of grass first, then after a while you won't care about any of the other stuff you wanted from it.

Technical info
Their site is pretty slow, because they use Amazon Web Services. This means, every time you submit, they probably connect to amazon to check you query. I remember Amazon had restrictions on connections - no more than one per second. Anyway, sometime ago I developed a desktop application to browse the Amazon store - both in C# and Java. I think I could easily adapt it to finding, if a given record is released under RIAA. It works much faster, than the website of course, since there is no proxy. Just tell me, if anybody is interested (I can release the source code under GPL or BSD) You can find pictures of it at the bottom of this page

Re:How do they do it now?
>Thus, they probably have another technique which cleans up the film grain by comparing it to subsequent and/or prior frames.
Yes, and you can try it yourself. Its VERY much worth the effort, even if it takes a lot longer to postprocess your video.
The more random the noise, the better. Its excellent for TV shows on VHS or from broadcast TV (or so I've found).
Oh, and if you like to make things disappear without noticing it (great for those HUGE ads in the corner of a TV show) try this, or this.
[Somebody with some experience please port these to Linux! You would be so well thanked! This would be really nice too! No, I can't do it myself, I'm really not that good.] -
Isao TomitaIsao Tomita (try Diskographia) produced an album "Dawn Chorus" which used these kind of effects. He took the waveforms from various star radio emissions and transposed them into his synth for the various tracks.
Most spooky and impressive is the intro track which gives the album its name. This is a transposed recording of the radio wave noise as the sun rises over the horizon at dawn. The pops, whistles and chirps sound pretty much exactly like a real dawn bird chorus.

FalseNot true. The SP/DIF can actually degrade the digital sound signal [by causing jitter] . If you want to know more about this please read the following two articles on the subject.
http://www.republika.pl/mparvi/digital.htm
http://www.geocities.com/jonrisch/jitter.htm
Btw.: Many [most?] sound cards use 48khz as an internal sample rate and upsample any sound signal that has a lower frequency. A 44.1khz CD track would therefor be upsampled to 48khz if input via the SP/DIF connector on the sound card. This, of course, degrades the sound signal somewhat.
