. . . machines are more and more being implemented in software instead of hardware these days. Where gears and spring-triggers may have been used before, now sensors, cameras, and servos are used more and more often instead.
OK, one more time "Companies don't set prices, their customers do!" (assuming a rational free market) The price is limited to the amount people are willing to spend. Companies often do eat the taxes as they don't want to lose customers to their less polluting, more efficient competitors.
Don't mod me down, I realize I'm leaving a lot out, and sometimes the only choices are to pass costs along or go out of business. But it makes at least as much sense as the mindless meme the parent parroted
If I had mod points, I'd mod you up.
I remember reading something about a Bush official talking about how terrible and obsolete the old Lotus system was and how they had modernized the system by going Outlook and Exchange. (ouch)
On the other hand, it's not hard to imagine that these particular "mislabeled" emails were lost for other reasons, inadvertant or otherwise.
Everything has value only because of what markets will bear. Thats a basic premise of capitalism.
Sorry, but I can't let this go, I'm too irritated by how it keeps getting repeated mindlessly.
Things have value outside of the marketplace, even if $ prices of those things are set by the market. And some things even have value outside of monetary value.
Modern humans didn't exist 640,000 years ago.
There is no evidence of humans living in North America until around 14,000 BC (or maybe 40,000 BC, it's hotly debated)
So your declaration of human survival is not comforting to this resident of North America.
If Yellowstone blows full on, you're talking smothering ashfalls as far away as Iowa. In addition to many millions dead immediately, agriculture would be devastated throughout the world, and for years in North America. The world hasn't seen anything like it in over 600,000 years. Civilization may recover in a few millenia, but I wouldn't use the term "bounce back".
You hiked (sorry) hunted in these forests, and you could tell by looking at fuzzy creatures that these forest farms support the same amount and diversity of wild creatures and plants? I assume you don't know the difference and don't care.
People have always been happy about getting more targetted ads.
Not me.
If I'm not purposefully seeking out a particular thing, I want a broad spectrum. I hate being pigeonholed, and enjoy becoming aware of new things.
The dollar amount to fix the issues, including man hours to remove the software, is unknown but estimated at $1.2 million to $1.6 million . . .
. . . put together a districtwide technology audit that cost $15,000. The audit was discussed Nov. 5 at a school board meeting.
The four-month audit has uncovered many problems within the technology department, and suggested district officials reorganize the information technology department. . . .
The problems include a network system not designed to handle the district's growth, a system in need of substantial repair and a building needed to securely house the network. There are also cabling problems and a lack of tracking inventory for technology equipment that is three years out of date.
It will take at least a year to fix all of the issues, Birdwell said.
So, it seems like the $millions is not the cost of running SETI@home, but the cost of doing things like construction to house the network, out-of-date equipment, repairs, etc. I mean, really, it's his fault they need a building?
It seems very doubtful that this is all Niesluchowski's fault; more likely, it's mostly the fault of an insufficient IT buidget.
And how hard can it be to uninstall SETI@home? They make it sound like an ordeal.
The major disadvantage of using 480 (V) to power a server, is you can't use a UPS. UPS on 480 (V) systems are rare and expensive, hence the reason why Facebook wants the batteries inside the server.
Rare and expensive for small systems maybe, but 480V UPSs are fairly common on the construction projects I've worked on, at least for larger systems.
i'm pretty certain you really don't want to run servers from the 277 (V) line to neutral voltage of a 480 (V), 4 wire system (3 lives, one neutral). On a 4 wire system, you have 4 wires and you can lose any one of them. If you lose the neutral, your servers could be running of 480 (V) instead of 277 (V). They will be destroyed.
Maybe I'm not that certain (being a mechanical engineer and not an electrical engineer), but if you lose the neutral on a circuit, you'll open the circuit and won't destroy anything. Anyway, 277V is pretty common for single phase loads like lighting in buildings where 480V 3Ph is available, why not for data centers?
Nuclear power produces base-power, it can not produce peak-power. . . . Currently only oil and coal have that ability
I don't believe that coal is considered as a good candidate for turning on and off rapidly in order to meet peak power demand and oil is pretty expensive compared to most other energy sources. Around here (northern Illinois) most of our base load is met by coal and nuclear and most of the peaker plants are natural gas. Looking forward, solar has a potential for providing a significant peaking capacity in the cooling season, when A/C loads match solar availability pretty well. Also, I'd bet that most electricity is not used during peak hours, unless you stretch the definition of peak hours to a larger part of the day than is usually brought to mind by the term "peak".
You started a great roiling discussion about the constitution here, but do you really think arming law-abiding citizens with handguns will lead to a reduction in murders? It's mostly gang members shooting other gang members (and the frequent accidental shooting of bystanders that goes with that) with automatic weapons. Law-abiding citizens practicing self-defense don't usually enter into the equation.
What part of "the right of the people to keep and bear arms shall not be infringed" is so difficult for people to understand?!?!?!
The part where their kid gets shot by someone bearing arms.
(mods, please note, I'm not arguing a point about the constitution, I'm answering a question. Even though it was probably meant to be rhetorical, the question has real answers)
The crays full immersion coolant model hit a big problem - the coanda effect.
You did not describe the Coanda effect, you described boundary layer issues. I don't know enough about the story to know whether boundary layers were the real issue: It's pretty routine to take into account the fact that friction causes the fluid velocity to approach zero at the surface of a stationary object, and to account for a lack of turbulence in the laminar part of the boundary layer that reduces heat transfer. It could just be that they needed to get a phase change at the surface in order to pull away enough heat.
By the way, the Coanda effect is the property that causes cold air being thrown horizontally out of a ceiling diffuser to stick to the ceiling rather than fall in cold drafts. The air stream is squeezed by the supply opening, and therefore has to speed up to conserve mass flow. It gets that extra velocity by losing pressure, so the air supplied is at a lower air pressure than the room air, and, as a consequence, is pushed up against the ceiling until it mixes with the warmer room air and slows down.
The issues of water cooling a data center go WAY beyond the case, which is why nobody has really done it yet . . .
They've only been doing direct water cooling of data center computers since the 1950s. Though the last time I worked on one was in the 1980s, and it was mainframes, not PCs/blades.
At the risk of seeming to support an fairly inept analogy:
Bridge designers understand a lot of things required to make sure bridges stay up. But I'll bet that many, for example, will specify grades of steel, types of paint, and other materials by reference to standards, without knowing the physics behind exactly why those particular materials perform as they do. Indeed, some of that physics/chemistry may not be fully understood by anyone, but rather based on empirical evidence.

Sensor, cameras, and servos are not software.
But you can both copyright and patent a machine's visual design
Don't confuse a design patent with a utility patent, they are really not the same thing.

Apple doesn't sell an Operating System. They sell "an experience." I'm not interested in "an experience" . . . I . . . chose to buy Windows XP.
All the XP "experience" advertising that MS did must have missed it's mark.
Except that down in the comments one noted that some of the sites without redundancy now used to have redundancy before the upgrade.
It has been a front page story already. After all, we wouldn't want any dupes
but it is a negative feedback, do some research.
but there are many negative and positive feedbacks, . . .
You are all wrong.

but, anyway . . . I lived in Chicago most of my life, and it's a great city to live in, as cities go.
The corrupt democratic machine has ruled Chicagoland for years. Obama was part of it.
You obviously don't know what you're talking about. Obama was not part of what is known as "Chicago machine politics".
More importantly, the experience with England clearly shows that cameras don't do much to prevent crime
Even more importantly, most of the police cameras are at street corners generating traffic ticket revenue.
