converts that radiation back to usable electricity. Quite a different problem. I suspect that's what they're pioneering here
They've apparently pioneered something called a "diode". It's thought that some day we might use the same technology to modulate the amplitude of these "radio waves" to transmite voice.
Addendums to your message: With a true 400 watt power supply, you can easily power 16 drives reliably. For reference, 8 drives pull a total of about 5-6 amps on 12v spin up, for about 1 second, then together use less than an amp on 12v, and very little 5v. This is based on testing with Maxtor 5400rpm drives, 7200 probably use a little more, and other brands may vary.
Power specs given in hard disk spec sheets are mostly boilerplate and do not reflect actual power consumption, the actual consumption is usually much lower than the spec.
ATA doesn't support delayed start, your power supply has to be able to take the full startup. 3ware makes controllers that support up to 12 drives, and hot swap when you use thier hot swap bays. A setup like that isn't cheap compared to the Promise card, but it may be worth it if you are testing hundreds of disks.
You don't think a 750kv lines use power levels high enough to induce current flow at a distance? Try taking a flurescent bulb under a HV power line at night sometime.
An interesting "real world" parallel, if you were a mechnical type worker, you would generally own your own tools, and take them with you when you leave the company. If you made up some jig that let you do some common thing faster, it would go in your toolbox, and you wouldn't have to make another one at the next job.
So really, doing what you do just brings us up to the level that most professionals have been for years.
That's a good point. I've never worked around nitrogen, but I have nearly fallen on my ass after sucking on a helium balloon to talk funny. Those inert gasses can really sneak up on you.
He does, however, need to make it clear that the people he is selling the program to have the same rights as he has, with regard to selling or copying the software. That is really the thing in question here. Several of his statements tend to imply he is the only authorized distributer of the software, which, if nothing else, violates the spirit of the GPL.
Without seeing the software itself, it's hard to say whether he has retained the GPL notices within the program or not, and whether they are "prominent" as required by the GPL.
What he is doing very well may be permitted under the licenses. I'm no legal expert. It seems a little sleazy to me, but that's just my personal feelings.
Can't hurt to call attention to it in any case. If what he is doing is OK, then it's free publicity for him, if it isn't OK, then the attention will hopefully get him to comply with the licenses.
A company named Luxuriousity run by Gregg Collins is apparently rebranding well known open source projects and selling them on Ebay. He gives no indications as to the original title of the software, and he even goes as far as to claim, 'Be careful who you buy from, only Luxuriosity offers a complete package including full support and refund services.' and 'We are a licensed Community distributor.'
I've submitted this as a story twice, the first time it was accepted, but not posted (Slashdot went down, I think it got lost), second time rejected. Anyway, it seems like this is a good story to post it under, since it's basically the same story as this one.
Phase change is indeed a valid way to power an engine, we've been using it for hundreds of years. It's just not very easy to control usually. You don't see steam engines on cars for a reason, a steam engine is really good at going only one speed, full out. To slow the engine down in general, you have to let everything cool down, or just let it blow steam for a while. That's wasteful.
Heh, that reminds me of box of computer stuff we got in recently at work. The thing weighed at least 150 pounds, but somehow the UPS shipping reciept had "40 pounds" on it. I think the scientists should definitely look into this.
History is littered with examples of solutions that were argubly not as good winning out over (usually more expensive) but better solutions. VHS/Beta, Windows/OS2, ATA/SCSI/FC (give it a couple years), most MS apps, the list is long.
Anyway, the key to winning is, "Do something that the competitor does, and do it cheaper, and at least acceptably well" That has been MS's long time strategy, except theirs has been "Do something a competitor does, and use monopoly power to bundle it for free". It's hard to compete with free, which is probably why MS is scared of OSS.
Well, you could get creative with CTCSS tones and voice recognition to implement something similar over normal analog broadcast. It isn't as potentially secure as this though.
It's cool, but I don't think it would scale as well as you think it would. Have you ever tried putting 10,000 802.11b nodes within range of each other?
BTW- You know, I never understood on Star Trek why sometimes they tapped the badge before talking, and sometimes they didn't. Seemed pretty inconsistant. I guess they could explain that by saying there was a sort of VOX mode that wasn't always enabled.:)
I respect people that can do it, but I don't take their word as gospel.
Applying their standards to all situations and all companies results in a lot of wasted time and money. You can get two or three nines a whole lot cheaper than five. Lets call it the 99.99/0.00999 rule.:)
Linux doesn't really care about the BIOS when it comes to detecting drives. Are you using Linux?
I think Windows still listens to what the BIOS tells it about disks, but in Linux I sometimes just tell the BIOS to ignore the hard disk detection to speed up boot times. What the BIOS doesn't know won't hurt it.
In any case, it still sounds like a software problem. The only hardware that would have to be implemented is a sequenced connector that properly disconnects the power before the data to avoid problems. The normal CF connector probably already does this.
I didn't say they didn't do a good job doing what they do, I was merely addressing the earlier poster's assertion that a normal host CPU couldn't do realtime streaming compression.
Hell, I was running doublespace on my 486's hard disk with not much appreciable slowdown.
I also wonder what he thinks is in those tape drives doing the compression, it's likely something like an i960 or a MIPS processor, something pretty slow by today's standards.

They've probably demonstrated this from within the near field of the transmitter, something that isn't difficult.
I have a feeling we won't hear any more about this "technology" (which is 50 years old). It's probably a borderline scam artist fishing for VC money.

I'm not sure I want to know how the semen gets from the straw into the cow. Especially if it involves a line from a Marylin Monroe movie. :)

OK, maybe a bad comparision, lets say it's more like calling the AMD PR rating "Mhz", because it's the same speed as the equivalent Intel Mhz.
See what I'm saying? I just think it's dangerous to call it Mhz when it really isn't.
Really shouldn't call it 800Mhz, the bus is 200Mhz quad pumped. It's kinda the difference between baud and bps, even though that got blurred too.
That's a good point. I've never worked around nitrogen, but I have nearly fallen on my ass after sucking on a helium balloon to talk funny. Those inert gasses can really sneak up on you.
Well, sorta. It used to be called the General Image Manipulation Program. Years ago.
The only deception is that he is using the ancient name for it that is no longer used.
He does, however, need to make it clear that the people he is selling the program to have the same rights as he has, with regard to selling or copying the software.

Technically this may be correct, and I even used to correct people about it, but the dictionary goes against this.
m-w:
an abrupt change, sudden increase, or dramatic advance
Looks like the term has been co-opted to this other meaning.

You don't have to be better all around to "win".

I've got my company's vital data on ATA backups. Lots of redundant ATA backups, with external checksums, multiple layers of RAID, etc.
If we lose this data, I lose my job. I am indeed putting my ass on the line with ATA RAID. I'm that confident in it.
Ever unplugged an IDE drive, then connected a different drive, without rebooting?
Yeah, but only with a 3ware card.
I hope SATA makes this more of a reality at least. It's supposed to be hot swappable by nature.
