Single-instance store is good for small to middling groups that use email to exchange large documents among large percentages of the group. I'd say that's a pathological use of email (but unfortunately common:-). But in larger groups (I'd say that 1M users probably qualifies) the single-instance store doesn't buy you much. This is from analysing real data from real-world email installs. I used to work at Openwave (nee Software.com) where our bottom-end product scaled to 250,000 users on a single server and our top end software was used by like likes of Verizon, AT&T and others in the "carrier class" realm. In that sort of arena, the only mails which are likely to go to more than 50 users is spam, and you want to recognize them and kill them.
I suggested this to a friend who works at Apple. The lightbulb went on in his head that with all the contacts/data on his iPod it was be a good idea. I wonder if that's why the nano has it?
I wonder if they'll upgrade the other iPods with a software update.
Well, the companies who were selling the weapons to the mujahadeen thru the CIA are doing gangbusters now. So, it might have backfired on the USA as a whole, I think it worked out for some people just fine...
Well, maybe. It may also be that it would be like importing the Cane Toads into Australia to control another pest. The outcome is difficult to predict, and could cause devastation locally in where the ocean was seeded or cause a chain reaction which would spread the devastation widely. Certainly more study should be done before we just start dumping massive quantities of iron powder in the oceans.
I hate it when people keep trying to say that humans occupy such a small area and try and say we have little impact because that just is not true.
But I started off by saying that humans have a huge impact. I guess I wasn't clear in the point of the entire post because most of the replies attacked the part of the post where I said we occupy a small area. (which I stand by: http://www.conservation.org/xp/news/press_releases /2002/120402.xml ). On the other hand, I guess I should have RTFA, or at least RTFS (summary), instead of just jumping to the comments and trying to answer someone's question, since I assumed that 'Earth' in the title was 'planet earth', not 'soil'. In response to the article I find it interesting that the soil is (perhaps) losing it's ability to hold CO2 due to the rise in temperature despite the raised atmospheric levels. The article I pointed to in my initial reply talks about using iron to cause phytoplankton blooms which would draw CO2 from the oceans, which would then draw CO2 from the atmosphere to maintain equilibrium. I would think (on first glance) that with rising atmospheric levels, the soils would absorb more CO2 (via osmosis) not less (though that may be true with a constant temp). Anyway, I agree we are (at least most of) the problem, that my post was unclear, but I did think that volcanos released more CO2 than they apparently do. Seems like the highest output from a single volcano is about 1/1000th of humans, but it's about 300 times higher than the 10th highest, so overall volcano output is probably on the order of 1/1000th of humans.
Oops, I dropped a 'y' on the initial 'They' of that sentence there. But I don't think that confused you. But at least _some_ scientists believe the entire earth was covered with ice some 600 million years ago. From the initial result of googling for 'snowball earth': Many lines of evidence support a theory that the entire Earth was ice-covered for long periods 600-700 million years ago. Each glacial period lasted for millions of years and ended violently under extreme greenhouse conditions. These climate shocks triggered the evolution of multicellular animal life, and challenge long-held assumptions regarding the limits of global change
That's from some small northeastern school (Harvard), but I got my initial comment from a program called Miracle Planet: Snowball Earth on The Science Channel. See some of the other replies or google around.
The other reply and the wikipedia entry cover it pretty well, but I got my data from a program on the science channel (nee the Discovery Channel) called 'Miracle Planet: Snowball Earth' produced by the National Film Board of Canada and NHK Japan. I've got it on my Tivo, and could probably put it on VCD if you were interested...
Oh certainly. I was just addressing the article title "earth releasing...'. I'm not one of those people who thinks we're not to blame, or that we need to study it to death before we start taking steps to alleviate the problem. (though I do question whether we really can 'destroy the earth', given life's resiliency. We may not make it though:-)
Well, the earth is huge. Sure, humans have a huge impact on the earth, but the area we occupy is a small percentage. Volcanos put out large amounts of CO2. The believe that when earth was a complete snowball (entirely covered with ice) it was the volcanos putting CO2 into the atmosphere which warmed the earth again (despite the high reflectivity of the snow/ice).
One of the approaches I've read about which would be high-impact for low effort would be to seed the shallow seas with powdered iron. From what I've read that is sometimes/often the limiting factor on growth of algae is the lack of iron. So the idea is to add iron to the system, the creatures (not sure if it's just algae, or diatoms or what) grows and sequesters CO2 and sinks to the bottom of the oceans. Of course this can cause lots of problems while the environment changes (red tides kill fish...), but may be our best bet to stop the CO2 increase.
This will be the end of both companies. Luckily I don't really care about the software from either. PDFs are nice, but since it's an open standard I don't need Adobe for it. Macromedia just makes annoying advertizing enabling software as far as I can tell. I guess if I can't get a 'modern' copy of Photoshop (OSX-intel say) because the company has cratered that might be an issue, but I don't use is professionally, and I imagine other companies will setup up to fill the void.
You are wrong that we don't know how to make memory as fast as the CPU. It's that it's not cost effective to do so. It's also a case of decreasing returns. That's why you can get away with the different levels of cache which run at different speeds.
Mostly correct, but Single User Mode won't help you get rid of a smart rootkit. A smart rootkit will include a filesystem shim so you can't find any of the files that make up the rootkit. also, executing things like/bin/bash might run a different program than just reading/bin/bash (for checking checksums). Basically, once you're root in unix you're god. The kernel can be replaced and from there the game is over. Only way to deal with it is to boot from known-good media.
It's not a myth. It _may_ not be a problem with more recent hardware, but with _my_ Sony DCR-TRV9 it _is_ a problem. And I find it unlikely that even with recent mini-DV cameras that if you fast forward past the end of the recorded part of the tape that the camera will lay down consistent timecode.
I think the "'we' shit" (interesting choice of nouns there, given my interpretation of the 'we' part) is _humanity_. There are certain things that 'we' (at least the majority) have decided. Things like molesting children == bad. That may not extend to all human societies but I'd bet it goes for better than 95% of humanity. Of course the definitition of children varies quite a bit, from 21yo to first menstration.
Anyway, I think TBL was saying that just like when a group of people get together and try to create a government which will support their ideals, the population of the internet needs to come together to ensure that the internet supports their ideals.
Well, you can use nuclear energy to heat a reaction mass and use the extreme temp/pressure created to eject the reaction mass (non-radioactive) from the engine.
The thing about prerecording the entire tape is that when you go to record anything later, the camcorder will read the timecode you laid down previously and continue it. This keeps you from having to record over the last bit of what you recorded previously to keep a consistent timecode on that tape.
Trouble is, you can't afford to ignore microsoft. They'll kill you. Especially after they figured out that the government was the one thing that could rein them in, so they bought it.
Well, I'd have to say the the vast majority of people are unsuitable as friends for me. They live more than 2 hours away, don't have internet access, and/or don't speak a language I can speak/understand. So, pedantically he's right.
On the other hand, my wife and I have had pretty good luck meeting people on Craigslist (including an agnostic, recently converted to judaism [I'm an atheist, and my wife is 'generic christian'). Of course, already having a friend/wife helps, since it's a sort of prequalification...

Did they develop the Browser?
No NCSA did.
Wrong. Tim Berners Lee developed the World Wide Web on NeXTStep while at CERN. The original browser was named 'WorldWideWeb.app'.
How was 'plug and play' (or other Microsoft projects) a 'pioneering effort'? Macs worked that way since they supported add-in cards!
Given that it is djbdns, I'm not worried, but having a test suite for vulnerabilities is a good thing.
