you probably burn it more efficiently in a less poluting way than the Chinese are currently doing with their factories and cars
Sorry to burst your bubble, but the Chinese do really strive to improve the MPG ratings of their own designed cars and trucks. Unlike the simpletons on this side of the Pacific who think that 15MPG is OK for a car that basically moves around some 90 lb of anorexic homo sapiens.
Got me! Yes, I mostly run Linux (FC flavors) and, after the second HDD began making the tell-tale noises, I started noticing that in Linux it is hotter than when running Windows and stumbled upon the hdparm settings.
For a reason I do not understand though, the hdparm setting is not saved between reboots (even if it's written in the/etc/sys-something/... files, don't remember the actual path now). The good thing is that I reboot very seldom (every 2-3 weeks) so it's not a problem to run it by hand.
Thank you for the laptop-mode pointer. Will look into it.
I'm at the third HDD on mine. The first two lasted less than 6 months each.
Now, when I place my D600 on the desk, I slightly raise its front side (with a thin eraser) so that air can pass under. This 3rd HDD is running strong after more than one year (keeping fingers crossed...)
I was driving to work one morning some 3 weeks ago while listening KQED (a public station in San Francisco) when suddendly, after some weird, piercing buzz noises, a voice that felt like those story-tellers in the 50's B-movies said that "this is a test blah blah blah, do not act based on this message etc and this is from DHS". After another set of buzzing signals, the station's program went back.
It looked like the guys in the show did not even know that their program was run over by the DHS message. How is the message inserted? In the studio, at the antenna level, or it's some sort of jamming-over?
Try to learn French and then you'll see illogical spelling (silent h's, e's, s's, even ent's (ils form), etc)
Heh, that's because you're probably a native english speaker.
Coming from a country that spells fonetically, both english and french are second (third?) languages. Oh boy, english is so much harder! The first rule you learn is that all rules of pronounciation have lots of exceptions and your only recourse is to learn how to deal with lots of words that need special treatment.
IMO, one sign that shows how difficult is to really learn english is that, unlike you learn it when very young and in native communities, you'll never clean-up your accent. Unlike français.
... as Norway was covered in rivers during this time.
Come on, are you telling us with a straight face that one can determine river beds existance from 200 ma ago in a geologically active area such as the Scandinavian peninsula, so prone to erosion?
You know very well that big pharma's money does not go into R&D, but more in making the product marketable. Most of the hard-core R&D happens at universities, very often supported by public money.
Some while ago I read that the pharma industry has the largest percentage of revenues going into advertisment. Surely some money wasted on "airy music and happy faces" TV ads could go into R&D, isn't it?
Furthermore, this industry as a whole stopped long time ago bringing in truly innovative medicines; maximizing profits always trumps useful drug development (think Claritin vs. malaria-fighting drugs).
So please, don't cry for these SOBs. The human kind would benefit greatly if there would be no drug-related patents.
Perfectly true. However, these days a dose of I-forgot-what's-its-name can be injected in the mom (in the first 48 hours after birth) that makes her capable of having a second child.
CNet brought Apple into the story to give it some interest.
Clicked the link, typed CTRL-F apple Enter. No hits, except for some unrelated headlines.
I guess that CNet did not mention Apple after all so all people mouth-foaming about the link to Apple base their trolling on an ill-written, idiotic post.
My guess is to simulate a conversation, although I think that it'll generate a Larsen effect.
Otherwise, with no sounds to be transmitted, I presume that the codec in the cellphone will mute-out the background noise and transmit fewer bursts of power (which cook the egg).
Anyway, if this is not an early April 1st, I really wonder what does it do to the brain...
Isn't it interesting how in each such article there's a shithead sitting on the fence and giving advice to the guys who do the work?
"It kind of makes you wonder about how serious they are about search," said Danny Sullivan, editor of London-based SearchEngineWatch.com, which tracks the search industry. "It really ought to be their goal" to be No. 1, he said. "Whether it's realistic or not." That "whether it's realistic or not" cracked me up.
It shows how true is the old adage "who can, does, who can't, teaches".
However, your statement that... OEM partners, who in turn carefully couple the CPUs to circuit boards with traces perfectly matched to one another, as well as to the impedance characteristics of the solder they're using, and attach them to advanced power supplies... is a little off, especially in the case of a VR for notebook CPU.
You would not believe what motions the ODMs go through to shave off that extra MOSFet switch or output capacitor, all in the name of saving pennies! I can tell you from first-hand experience that most VR designs happening since a few years ago violate in some way or another the Specs Intel or AMD provide for their CPUs (larger ripple, a little too much overshoot in load transients, bad loadline etc). This is regardless of the brand name, as anyway most OEMs (some Japanese makers being the exception) delegate the design to the ODMs while in the same time placing awfully tough cost constraints on them.
The only slightly better built systems are the ones labeled "commercial" because the selling price can be higher and there's more room for decent design.
Desktops and much much better built and this is just because there's more space there, the competition is more heated and simply because there's more granular choice than with notebook products.
Ooops, got carried away and did not really refute the dumb claims the OP made. Yes, the CPU is a monotonic load (i.e. when the voltage decreases, the current decreases).
The OP may have had in mind some constant-power type of load, where the current consumption is (indirectly) driven so that the output power stays the same. From the I-V perspective, the CPU is a glorified non-linear resistor.
Instead of lowering the power consumption, you'll get higher amperage spikes as the equipment draws more power to compensate.
Sorry, this is wrong in the context of a CPU power supply.
When you lower the core voltage, several things happen at once:
1) the power dissipation due to the clock switching is lowered with the square of the voltage reduction. i.e. a reduction from 1.3V down to 1.1V will reduce this power component by 40%
2) the power dissipation due to the junction leakage and off-state punchthrough decreases by the ratio of the voltage.
3) but the switching speed of the MOSFET transistors decreases.
Effects 1 and 2 are good as they mean an overall lower power dissipation. For 90nm processes and up, effect #1 dominates. For 65nm and below, the effect #2 becomes increasingly larger.
The downside is #3. Lowering the voltage means that some critical paths inside the CPU logic could become longer than the clock period, generating timing violations and system crashes. The only remedy against this is under-clocking.
In the end, the one thing you can gain by under-volting is the margin between your particular CPU and the lousiest one in the same class that will still perform OK at the same clock speed. As each CPU is tested and binned especially for power dissipation AND maximum clock speed, this margin is low and the gains minimal. And you spend a lot of time to find out what is the lowest safe voltage.
If you want less power dissipation and longer battery life, under-voltage and under-clock. This is done automatically already in the mobile CPUs, both from Intel and from AMD.
Scrapping IE and adopting one of the competitor browsers amounts to a face-losing situation. For the company governed by the Dancing Monkey, this is not acceptable.
So no, it's very probable that Microsoft will stick to their own browser.
The problem is that the wattage you mention is for the entire system, not just the CPU.
This makes also Anand's comments w.r.t. the AMD/Intel consumptions disingenuous at best. It's hard to measure the CPU power, but if he wanted to compare the CPUs, he should have done his homework.
Based on the delta wattage (16W, including all other loads, e.g. memory access) and the fact that in a 65nm process the idle current is still less than 40% of the full-load, I'd say that yes, this is a very low-power CPU (to be branded as 25W maybe?), perfectly suitable for a notebook.
Sorry to burst your bubble but if you're 18 and just "feel" the TV line sync (about 16kHz in Europe and only 15kHz in US), then your hearing is pretty lousy.
For a typical young, undamaged ear drum, the "feeling" reaches easily 20kHz (e.g. you can not only feel but hear as well the 19kHz stereo signal carrier of a cheap FM radio).
High, never flexible price and, of course, the resurrection of its arch-enemy from the death.

Eh, for a goodie that costs a few hundred bucks I do expect 0% out-of-the-box defect rate; that's what QA is for.
The fact is that MS shipped a relatively small volume (what, maybe half a million at launch?) as of yesterday and if you care to hit google you'll find that the failures are not "anecdotal evidence on Slashdot".
On another topic, you should improve your sarcasm technique, it pretty much sucks.

Whoa, you must have pretty low expectations in general! When did it become acceptable to buy defective goods, on the presumtion that statistics may be in your favor?
A game console is by no means more complex than e.g. a notebook computer. If any NB manufacturer would ship systems with an out-of-the-box failure rate of 0.2% (which is a fairly optimistic, i.e. low, estimate), then that company would go tits-up in no time.
The weird thing about game consoles is that there are too few makers, limiting severely the choices users have when buying them.
