re-reading his post, it sounds he was making an academic point. I originally read it as him making a statement about how we could proceed with fixing our energy woes.
Of course it's possible to do what he says, IF you have the energy input to do it. But that's the rub, isn't it?
anyway, my bad for mis-reading. I Do have a clue about where our fuels come from, apparently what i lack is reading comprehension skills;)
The same "fuel" can be burned an infinite amount of times as long as you have energy to convert the exhaust CO2/H2O back into hydrocarbons plus O2.
wait wait.. you can take a finite amount of fuel, burn it, recapture the waste, convert it back to a useable form, and reuse it? that's brilliant! if you could automate the process, the resulting machine could stay in motion.. perpetually!! like a... perpetual...motion.. machine!! you've solved our energy problems!!
how about the other way? instead of cutting the delay times by 9% (maybe not a big deal), they cut the number of delays by 9%.
given roughly 28000 commercial flights per day in the US, if 10% (number from my ass, but i imagine it's low) are delayed, you're talking about 2,800 delayed flights. 9% of that is 252 flights per day that won't get delayed because of the new system. 252 is a lot of airplanes, and who knows how long those delays might have been... 30 min? 2 hours? most likely much longer than your example. 9 min on the runway can often be made up for in the air.
Now, is it worth it when balancing that against the costs of the system? i don't know.
At this price, I'd rather spend the extra for 6 discs and RAID5 the backup. Better than the risk of having five very expensive coasters.
For mortals, sure, but the new stuff is always ungodly expensive when it first comes out. Especially when they're marketing it to places that have the money to pay for the convenience
Nobody is saying that one of these should be an entire backup solution. But if i have a 3TB database that needs to archived, i'd much rather use 5 of these than 4616 CDs, 639 DVDs, or even 15 ultrium tapes.
Data is getting so (too?) big that we NEED things this size just to be able to physically manage it all in any sort of convenient way.
As someone above posted, the current DOCSIS standard (2.0) in the US is capable of 43Mbps, but most of our cable Internet connections max out at 6 Mbps. So just because a new standard promises a way to get more bandwidth, I'm pretty sure Comcast isn't going to be giving us connections that can use anywhere near the amount that DOCSIS 2.0 can provide for a long time
Remember, though, that that 43mbit is divided among everyone on your node. Once your neighborhood gets saturated, they have to put another node in your neighborhood and pray that they overbuilt their fiber plant enough to have spare strands at the right location. Then they have to physically subdivide the nodes and.... it's a lot of hassle/time/money and good luck waiting for your cable company to get around to it.
Theoretically they could run another CMTS on another channel and distribute a second wave of cablemodems set to bond to the new channel, but you're still adding lots of very expensive equipment at the head end and vastly complicating the consumer end of things.
On the other hand, being able to bond 4 channels together and suddenly quadruple your capacity is a HUGE boon for everyone involved. you'll need to update your head end and consumer equipment, but DOCSIS tends to be backward compatible, so hopefully your old modems can operate as normal and the new modems will receive the bonding benefit as they get delivered to the customers. In any event, it's all cheaper than upgrading the physical plant.
great! how long do you think it would take people to code "ban this certificate" buttons that tie into the smtp server? Then it doesn't matter what the content is or where they send it from, if the email authenticated with that cert, it's rejected.
That's a single point of spammy identification. They'd have to buy lots of certs, which means that either spamming then becomes very (too?) expensive for either a) them or b) their customers.
sure but you woulnd't want the same mouse plugged into both computers similtaneously and taking input concurrently... unless you were trying to identically configure multiple systems. synergy and win2vnc both take advantage of 1 mouse and keyboard controlling 2 computers, but not at the same time. there still needs to be logic telling the machines which
now.. perhaps a button on the mouse/keyboard allowing you to toggle devices ala kvm hotkey but that's what a kvm is for, yesno?
the problem with that is tha their stocks were/are basically useless. that's why it was so devastating to everyone who had their pensions locked up in company stock. when the scandal came out, the stock prices plummeted and the damage was done.
If he had a milltion shares of enron and the price dropped from 100 to 1, that $1,000,000 is something to add to the pile, but was miniscule compared to what it cost everyone else. that's if enyone would even buy a million shares of the compant in that position for anything more than a few cents a share
selling all of their other holdings, however, would likely be more profitable.
that's all well and good, but it only shrinks the size of the cables, not the number of them. We need a consumer movement to demand standardized chargers.
Or, probably more effective, get a bee in some environmenally friendly congressperson's bonnett about how much energy we can save by having a unified charging interface (or 3.. allowing for size differentials) and eliminating the vampiric wall warts and get it legislated.
Would it take that much logic in a unified power supply and peripheral to have some signature wherein the charger knows it should doll out 5 vols to my camera but only 3 to my bluetooth headset? it can't be THAT difficult.
Why does it need to be custom-wired with DC line-loss from the basement? How about a plug-in (and possibly mains passthrough) wall wart with the all the requisite features, for current builds.
for new builds it could be a self-contained unit mounted in the box.... either in addition to or combined with a normal mains outlet. 1 mains connection to the unit would power the normal outlets and the new ones, with the necessary stepping happening inside the unit. Just throw it in a 2-gang box and it'd all fit nicely. I'm sure it would be far too expensive to do all of the outlets in your house, 1 or 2 in each room would be doable.
wrt inefficiency loss of all those transformers, it's probably less than wiring DC though the walls and certainly less than all the current vampire wall warts.
I imagine you'd have a shot at porting darwin to it, but even before we talk about whatever kernel changes they had to make to run PPC linux on the Cell, you can bet that the drivers for basically everything else about the mahcine are non-existent in OSX.
However, my money is that even if the hardware drivers were there, they used a quite hacked-kernel to make it work on Cell... good luck getting apple to cross-compile for you.
that's rarely an issue. the dns of your server doesn't need to match the domainname on your outgoing email. Most places jsut require that there be ANY rdns on an ip. Some get so specific as to check that the Rdns matched the server HELO, and others make sure that the reverse name resolved to the IP in the reverse.
requiring the domain on the email to match any of those is just plain silly and i've never, ever seen evidence of this.
Apprently you know absolutely nothing about encryption.
Fortunately the people who have created real-world encryption schemes are far far smarter than you and have worked out the 'miracle' of lossless encryption.
How about trying your example with pgp or idea instead of some half-baked BS straw-man example like the one you demonstrated?
I'm not sure what kind of tritium you're taking about, but normal tritium is a gaseous isotope of hydrogen that emite beta radiation -- can't penetrate human skin. by "very radioactive" perhaps you meant sheer amount and not strength, yes?
You wouldn't want to ingest it, but it's used all over the place as a poersource for glow watches and keychains so i can't see where containment is an issue.
Hard to believe that they have gotten so popular in the open source community with such restrictions in place.
I'm actually kind of surprised that debian still includes mysql with such a restrictive license. Or is it allowed because; you can use mysql for free (beer) so long as you keep your app free (speech)?
huh? who said anything about justifying socialst government snooping?
i was responding to your question about the affinity for tracking everything with respect to (your words):
For some reason there's no problem with print advertising in newspapers, or magazines, or trade journals, or billboard signs on the highway. Advertisers happily pay the fee based upon little more than a demographic and they take, at face value, the numbers related to distribution.
The marketers are the ones who are paying for it all to happen. The government getting their mitts on it is just an inevitable and unfortunate result of this, but the marketers are making their money so to hell with the consumers.
Whether or not there's a conpiracy theory behind it, all of this stuff if a marketing exec's wet dream. Think about it. Nearly instant feedback on what ad work, don't work, who the effective demographic is, what times of day who sees what. The savvy marketer could change their ads on a per-viewer bases, taking into account their location, time of day, likely age range, etc.. all to get the 'right' add to the right person and make the sale. It's all about a bigger bang for the marketing buck, and sending out 50,000,000 untargeted brochures through the mail isn't very efficient. Showing 100,000 ads to your precise target audience it likely very efficient. It's Nielson on crack.
true, though that was write speed, reads are even faster... still a fraction, but a more respectable one.
One thing that should be taken into account, though, is that this is all well and good for contiguous files. Throw in some fragmentation or just multiple sparsely located files and the aggregate seek times will very quickly close that gap.
This goes back to the rambus/dram argument of throughput vs latency... and in this case we're talking about latency differences measured in several orders of magnitude, that means everything for random data access.
uhh... i think you mean 12MBytes/s, but they're getting even faster than that.
I don't know what kind of flash drive you have, but mine runs a hell of a lot faster than usb1.1 speeds. I haven't tun hdtach on it but it but i just copied 87 megs of mp3s onto it in ~6 seconds, that's 14.5 MBytes/sec, or 116Mbits/s
looking back up i see you said flash card... dunno fi you think it matters, but my 512MB SD card is narly as fast.
Bravo. People are forgetting that '5.24" drive bay' and '3.5" drive bay' refer to the size of the floppy disks that were used in the drives that inhabited those bays, not the drives themselves.

no..3 bytes per pixel (1 byte per color) * 8 bits/byte = 24 bits per pixesl, which he already factored into his calculations
