But what is happening is BS. Unless ALL nations are involved, then nothing will change.
As it is, the largest polluter, China with more than 1/3 of the CO2 emissions, is being allowed to continue GROWING their emissions while only the west are to cut back.
This will NEVER succeed if this continues.

the only possible solution is if all nations cut back, and if they are cut back predicated on CO2 / $ GDP. The reason is that emissions are NOT tied to ppl,but dirty manufacturing.

The Hugo Award Nominees reading package last year includes the entire Wheel of Time series (which I thought was a classy move by the publisher, and a nice contrast to Orbit Books including only excerpts for their three nominees.) (If you're a member of the appropriate Worldcon, you're eligible to vote for the Hugos, and in recent years they've provided an electronic package of most of the written and graphical works that are nominated.) The bad part about this is that the tablet I use for reading has the bloody entire bloody Wheel of bloody Time series on it, and I'm about 90% of the way through :-)

I hadn't read it before Jordan died, and probably that wasn't my birthday anyway, so for me it wasn't the worst birthday present ever; for that one I'll have to thank my little brother for giving me chicken pox when I was 10. There wasn't a vaccine for it back then, but there is now, and if your parents didn't give you the vaccine and other kids didn't give you the disease, trust me, it's one of the vaccines you want to get. (I also got measles the hard way, but I was young enough I don't remember it very well. Got the polio vaccine, though, unlike a neighbor's kid who was a couple of years older and had to use crutches.)

Yeah, I probably should have blamed a different one of the non-length-limited strXXXX() functions, but strcmp() will still do Bad Things if you hand it one or two non-null-terminated pointers.

And yes, stderr would have been the better choice, but the important thing is to replace the implementations of dangerous functions with something that fails safely, and if you can't do it at compile or link time, it's still safer to do it at run time than to run the unsafe version.

In general, somebody who has loads of money will make use of these bands. Now, if I wanted to take a rich person as hostage for a payoff, I might get somebody close to them to simply change out some code. That way when rich person is walking around and device gets a signal, it says, here I am. Basically, an easy tracking device.

For us here in Norway PSTN/ISDN was our bad time, when the one monopolist could charge pretty much everything they wanted. When we got DSL, the market was deregulated and lots of offers showed up. In the US, far more people get Internet via cable, which obviously has far more reason to protect their traditional business. As for recent fiber roll-outs it's really the power companies that got the ball rolling there, eyeing an opportunity to break into a new market by running fiber optics as well as power lines. Obviously the incumbents couldn't sit around and watch that and it became a race to lay down fiber first, since it's rarely profitable to come second. So it's a very nice three-way race to roll it out, though the prices are fairly steep.

Even if the mean time between failures for consumer drives was 6 months, the odds of 'popping' two more spares in the month after the first failure would be less than 3%. If the MTBF is 1 year the probability drops to 0.7%.

Except if you got a bad batch where some kind of material or production defect will cause many disks to fail near simultaneously. The overall MTBF might be true for all the disks they produce, but unless you make a real effort to source them from different batches over time you can't assume that's going to be your MTBF.

What complete and utter bullshit.

95% of 250 coders. That means that out of a million programmers they will misidentify 200000.

You know it's not a contest to come up with the worst bullshit. If you're left with one person 95% of the time when you have 249 possible wrong answers, it's like being left with 4000 people when you have 999999 wrong answers. If all those are too close to tell apart you'll misidentify >99.9%.

Imagine for example that you wanted to find people by height and weight, as measured to nearest cm and kilo. It might work decently on a small group, but if you scale it up to a million people there'll be a lot of duplicates and then you're just guessing, double the population and you halve the chance of being right.

It doesn't bode well for Linux that it is also not the year of the Windows Desktop or Apple Desktop. It is the year of the smart phone. The year of the desktop may never return. Desktops are better suited for developers and smart phones are better suited to consumers.

Developers and a ton of other professionals. If Linux/FLOSS could replace Windows, Office, Outlook/Exchange, Sharepoint and SQL Server that's probably 15 of Microsoft's $26 billion dollar revenue. Open source has not managed to commodify basic business and collaboration tasks, despite so many years of trying. It's not all about smartphones and tablets.

That is 24%. That means your device could be 20% cheaper and they would STILL make more money then anybody else in percentage per product in the electronics world. So instead of 500USD for the Ipad2, you could be paying 400USD and they would still make money. And some people don't think Apple is overpriced.

Don't worry, you can buy a $500 phone from my non-profit, $400 will be my for salary and $100 for a junk Android phone. Profit is an indication that you're delivering more value relative to cost than the competition, after all sales price is just a number you decide. They're not competing against some imaginary non-profit, the day Google, Microsoft etc. deliver a competing product forcing them to lower prices they will. Until then, keep blaming the one delivering what people want and not the ones who don't.

There's no future in time travel.
