It is AMD fanboy sour grapes. For some reason some people get really personally invested in their choice of graphics card. So when the other company comes out with a card that is substantially better than what their company has, they get all ass hurt and start trying to make excuses as to what it is bad. The nVidia fans did that back when the AMD 5870 came out and nVidia had no response. Same deal here. The GeForce 900 series are a reasonable bit faster than the AMD 200 series, and way more power efficient. At this time, AMD doesn't have a response, so the AMD fanboys are going on the defensive.

The real answer is, of course, buy the card that works best for your usage, which will vary person to person.

The Red Line crash was not computer-related. The signalling system for the Washington Metro is a classic electromechanical relay-based system. Just like the New York subways. The Red Line crash was caused by a failure of a track circuit for detecting trains, trackside equipment using an audio-frequency signal sent through the rails and shorted to the other rail by the train's wheels. All those components are pre-computer technology.

As with most railway systems, manual driving isn't enough to prevent collisions, because stopping distances are often longer than visual distances. That was the case here.

The Washington Metro had been sloppy about maintenance of trackside equipment. They do have a central computer system, and it logs what the relay-based signal systems are doing, although it can't override them. They had logs of previous failures, and should have fixed the problem.

... Before that it can't, because Ta^4 - Tb^4 is a positive number so no net radiant energy is absorbed by (a) from (b). That means all the way up to the exact point thermal equilibrium is achieved, all radiant power is a result of electrical power, therefore the power input and power output are constant. It is not a "gradual" process. ... [Jane Q. Public, 2014-09-20]

So Jane claims:

electrical power per square meter = (s)*(e)*Ta^4

The actual answer is:

electrical power per square meter = (s)*(e)*(Ta^4 - Tb^4)

Since Jane refuses to include a term accounting for radiation from the chamber walls, Jane's equation is saying that no radiation at all is absorbed by the warmer source. Why?

... Since the chamber walls are COOLER than the heat source, radiative power from the chamber walls is not absorbed by the heat source. ... [Jane Q. Public, 2014-09-15]

Of course it is! Again, this is just Sky Dragon Slayer nonsense. Absorption doesn't work like Slayers imagine. It's controlled by the surface's absorptivity, which doesn't change if the source is slightly warmer or cooler than its surroundings. All that's required for the source to absorb radiation (from warmer or colder objects) is having absorptivity > 0. Since the source has absorptivity = 0.11, some radiative power from the chamber walls is absorbed by the heat source.

Jane's been regurgitating Slayer nonsense for years:

... Warmer objects cannot, and do not absorb lower-energy radiation from cooler objects. ... [Jane Q. Public, 2012-11-20]

Then how do uncooled IR detectors see cooler objects? How did we detect the 2.7K cosmic microwave background radiation with warmer detectors?

... explain how radiation that is of a LOWER "black-body temperature" will be absorbed by a body of a HIGHER black-body temperature. ... [Jane Q. Public, 2013-05-30]

... An object that is radiating at a certain black-body temperature WILL NOT absorb a less-energetic photon from an outside source. This is am extremely well-known corollary of the Second Law. ... [Jane Q. Public, 2013-05-30]

No, that's a Slayer fantasy. On the atomic scale, absorption of radiation doesn't depend on temperature because individual atoms don't have temperatures. Only very large groups of atoms have temperatures. Individual photons also don't have temperatures. Very large groups of photons from a 10C warm object have slightly different average wavelength curves than a -10C cold object, but they're very similar. This means that even if temperature somehow applied at the atomic scale of absorbing individual photons, an atom couldn't tell if a photon came from the 10C warm object or the -10C cold object.

... You took a badly-worded sentence or two and jumped on them as though Latour made a mistake. But his only mistake was wording a couple of sentences badly. He does in fact NOT suggest that warmer objects absorb no radiation, and he has written as much many times. ... You have refuted NOTHING but a couple of unfortunately-worded sentences, which Latour himself publicly corrected shortly after that post appeared. ... [Jane Q. Public, 2014-07-27]

Ironically, Jane's still insisting that warmer objects absorb no radiation from colder objects. Otherwise Jane wouldn't repeatedly object to including a term for radiation from the chamber walls in his calculation of required electrical power. Since Jane doesn't even include that term, Jane's assuming that warmer objects absorb no radiation from colder objects.

... shortly after Latour published that blog post, it became clear that the language he used implied that no radiation at all was absorbed by the warmer body. So a reader could not reasonably be blamed for inferring that. But Latour quickly apologized for the unfortunate wording and corrected himself to make it very clear he was referring to net, not absolute, heat transfer. ... [Jane Q. Public, 2014-07-27]

Ironically, Jane's still insisting that no radiation at all is absorbed by the warmer body. Otherwise Jane's calculation of the required electrical power would include a term for radiation from the chamber walls. Since Jane adamantly insists that this term can't be included, Jane's calculation assumes that no radiation at all is absorbed by the source. None. Zero.

It's truly surreal to watch Jane repeatedly double-down on nonsense which Jane claims is too ridiculous even for Sky Dragon Slayers (as if that were possible!).

Actually, the current response to airspace incursions in the DC area is an F-16 and a Coast Guard helicopter. The F-16 is in case it turns out to be hostile, and the Coast Guard helicopter is for the usual case, which is a clueless VFR pilot who needs directions. This happens several times a week. The FAA now insists that all pilots operating within 60 miles of DC (actually 60NM of the DCA VOR) take this online course. Amazingly, there are still clueless pilots wandering into this airspace, although fewer than a few years ago.

Take a look at the video. The drone is at least 1000 feet up. If it's painted dull colors, you probably can't even see it from the ground.

He meant 10 thousand CNC machines...not that they were $10K. That's an almost unbelievable number; and array of 100 x 100 CNC machines.

Some of that info seems bogus. 10,000 CNC mills? Unlikely. 10,000 CNC machines of all types across all of Apple manufacturing, maybe.

There's a nice video about how Apple machines a round can for their round desktop computer. They're going through a lot of steps to make a can, yet they're doing it in a low-volume way. Here's how soft drink cans are made. Same shape, but much higher production volume.

Apple is doing this to justify charging $2700 for an x86-64 machine with midrange specs.

There are amusing efforts to sell disk drives to Google. Near Google HQ there is a movie theater complex. I once saw an ad run before a movie. Two minutes of sales pitch for bulk purchases of enterprise hard drives, with lots of technical detail. Clearly this was addressed to a very specific audience.

don't need 16Megs. People on slashdot criticize apple for forcing you to buy features you don't need. Now you critize apple for making the base model something not geek worthy. they are offering what their customers need. Chances are the number of songs or photos you want to keep stored on your iphone at any time isn't geoing with time. and that's the majority of the space usage on most people's phones. With icloud and beats streaming that need is going to dramatically shrink as well. The only thing likely to really be a space hog is more tricked out games and things that use the greater pixels of the large phones. But as I said, at the moment it's photos and music that dominate the storage needs and those will be going down not up.

Yes alibaba is a theives market. Alibaba does little to root this out too. Moreover the entire china small items trade competiveness relys on the rediculous postage rates (low) that allows delivery in the US for a mere $1 worth of postage. Finally all the small vendors lie about the item in the postage to evade customs charges.

Amazon could make great noises and will.

On the other hand who owns Alibaba's 120 billion? Americans now. If the congress sicks their dogs on ALibaba it's the same as pilfering 120 billion from investors.

Meanwhile amazon has a PE nearing 1000 (who are they kidding?). AMazon's 1000 PE is justifed only on the basis of their growth rate not their earnings. If their growth is threatened (enter alibaba) their stock price crashes. if it crashes to a P/E ratio of 30 or 100 then 90% of the stockholder calue is whiped out. Gone. Not transfered. Gone.

So what's your poor bribed congressman to do. Act on alibaba's theivery to save Amazon, or not?

tough choice.

Alibaba's stock price over the next year will be a race between their growth in value, and the trees Amazon and E-bay fell in their path. I predict it goes up for 1/4 then down in response to regulatory pressure after the elections. THen eventually back up if their revenues grow,.

DoublcClick has such negative value that their servers should be blocked at firewalls, or at least "host.txt". Even if you have AdBlock, blocking them earlier saves bandwidth.

Note I said that both of them are living off their credit cards. I'm well aware of the poor state of the UK's finances.

Really? But by implication you'd be totally fine with closed source (as in Microsoft)? Just asking.

So you think fsck is something besides a descriptive abbreviation for File System Check? What about ls (List), rm (Remove), cp (Copy), or touch (literally, Touch File). Oh, I see. It's a pre-teen double entendre.

Did you just claim that mass shootings at schools in the USA happen less frequently than nuclear meltdowns?
