  1. Generic PSU + Good UPS = silence and acrid smoke. on Brand Names Take On Generics In PSU Showdown · · Score: 1

    That's a good analogy...until your bulletproof vest explodes while you're wearing it inside the armored car.

    No-name PSUs are built cheap-- lowest-bidder capacitors, heatsinks, fans, and circuitry. Even getting 100% solid voltage from a UPS, they have trouble staying within spec'd voltage ranges, especially under sudden loads.

    Under any real loads, budget PSUs will fail out with a good chance of killing your system, it's only a matter of time. Even before they go up in smoke you're, likely to face a nightmare of unexplainable system freezes and data corruption.

    Compare that with a high-quality PSU guaranteed to run off of AC input 100V-240V while supporting full rated load. Active power-factor correction implemented properly brings everything you get from a UPS except the battery. Mine runs happily through minor voltage problems-- lights dim for a second, my computer continues to run, roommates with weaker PSUs and an old half-dead UPS go down.

  2. I saved a lot. CPUs have to survive OEM builds. on Intel Quad-Core Price and Performance Showdown · · Score: 2, Informative

    There's absolutely no reason NOT to overclock Core2s. The small investment required to avoid cut-rate bare-bones parts gives you faster clock at stock/lower voltage with lower temperatures and much higher reliability.

    For goodness sake, you're using a CPU that has to perform reliably in machines cobbled together by *OEM* suppliers who have to slash their costs to the bone and use the cheapest possible components in order to not go immediately out of business. There's enough headroom in the designed ratings to massacre rated performance levels. Have you ever looked inside a Dell?

    Thus, my design philosophy is twofold: Excellent performance at a reasonable price with high reliability. For these reasons, I'm already going to spend more than a bare-bones system, so overclocking potential is a freebie!

    In my view, the most critical components for reliability in a system are, in order:
    Motherboard: Proven, tested, highly-rated enthusiast-quality mobo from a top-notch manufacturer. Abit IP35 Pro, +$80 over barebones.
    Power Supply: Well-reviewed supply from a top-notch manufacturer, with at least 100w headroom over expected use. Antec TruePower Trio650, $40 over barebones.
    RAM: Quality manufacturer, rated for where you expect to overclock to. - 4GB OCZ Platinum DDR2, say +$20, RAM is cheap.
    Case: Antec 900. No reason to get anything else from a performance standpoint, they're on sale regularly for sub-$100.
    Oh, and $15ish for a no-frills CPU fan that doesn't suck.

    So, $200-ish over a barebones system for massively higher reliability. What did that get me, a YEAR ago?

    Core2 E6750 OC'd 27% to 3.4GHz, 100% stable at stock voltage, running much cooler than the stock cooler did at 2.66GHz.

    I'll take that any day.

  4. The VA system isn't broken, it's ignored. on Saving 28,000 Lives a Year · · Score: 2, Insightful

    I don't know if the system's broken down or is just being mis-managed but at one time, I preferred military care over civilian.

    The military/VA care process is still better organized and more streamlined than the horrendous kludge of the private system, but it's also under a remarkable strain from a flood of war casualties and the rapidly-aging population of Vietnam vets. Ironically, the VA system provides better, cheaper care because it does not suffer from many of the inefficiencies of a market-based health care system-- preventive care and unified standards within a single provider make treatment much more effective and cheaper in the long run.

    The official count of American soldiers seriously wounded in Afghanistan & Iraq is over 30,000, even with political pressure to keep public casualty counts as low as possible by redefinition of 'wounded' and 'injured'. As of 2006, more than 100,000 disability claims had been granted by the Veterans' Administration for service in the GWoT.

    Advances in medicine, personal armor, and trauma response have enabled our soldiers to survive far more grievous wounds than imaginable at any time in the past, and our responsibility for providing appropriate and continuing care is growing with this trend. Unfortunately, it's hard to live up to our promises when the political establishment is united in their desire to sweep the consequences of war under a patriotic rug...

    It also says "I think I am more important than you, and that what I want is more important than what you want, and I am willing to break the law to act on my self-centered desire"

    Well, that's also 100% true. In fact, I have difficulty thinking of anyone who doesn't fall into that category when confronted with excessive asshattery... Fortunately, we work within the framework of our civilization anyway most of the time, because most individuals/groups also work within the social contract. DRM typically does not, so circumventing it in those cases makes sense.

  9. The left-right paradigm is a complete failure. on Discuss the US Presidential Election & the Economy · · Score: 1

    The lack of oversight responsible for our current financial system downturn isn't about who was loaned what by whom. It's about the mis-representation of the expected value of mortgage-based securities. Banks were tripping over themselves to loan to anyone with a pulse because there was a vast and incredibly hungry market for 'risk-free' investment vehicles of any kind, not because of government pressure to loan money. Mortgage-backed securities were being valued based on historical default rates from when only rational lenders were making loans, and it was assumed that housing prices could not go down, despite increases of 1000% in a decade in the hottest bubble markets.

    Banks had no incentive to vet their mortgage applications, because the mortgages involved were being bundled, securitized, and sold off to investors on a timeframe that got the banks out within weeks or months. Put enough securitized, tranched, bundled, split, re-bundled, and shredded mortgages together, and it was just miraculously assumed that the resulting vehicle would be 100% as safe as the real-estate market as a whole.

    Irrational Price Setting ==> Market Failure. Do not pass go, do not collect a pension -- the market system does many things very well indeed, and when it fails, the failures are even more spectacular.

    So, Obama will quite likely pursue some policies I do not agree with. The Democratic Party certainly has elements that I oppose completely-- I can't stand the rabid protectionist/isolationist/anti-trade idiots, the fear-mongering shills who want to trade liberty for the illusion of security, or the corrupt unions and self-serving bureaucrats.

    But the bottom line is, Obama at least appears to perceive the same universe I do, while the Republican party's positions seem to be based on a controlled-inbreeding program of talking points that completely detached itself from reality years ago. They've left most of the positive elements of conservatism to nailed to a cross of rhetoric, and bankrupted themselves in the process.

    No Big Government! No Death Tax! Liberals hate America! Illegal Immigrants are destroying America! The government can only keep you safe from TERRORISTS who hate America if you do everything we say! The Government should control your Right to Life! Tax breaks for the wealthy are the only way to preserve businesses that make our way of life! Socialized Health Care is the Government taking your choices away!

    So, I'm hoping Obama can keep the nutjobs from his own party in check, because at this point there are no other viable options. McCain in 2000 would have been a visionary President, McCain of today has sold out to clamber to the top of a corrupted party machine drunk on power, willful ignorance and intolerance.

    The left-right paradigm is a failure. We're left with two camps drawing battle lines along issues which aren't relevant across a crazy patchwork that is no longer even remotely consistent. I want someone to stand up for rational thought, open discourse, and a complete re-evaluation of the 'givens' that both parties take for granted in their rush to take a stand on things that in the end truly do not matter.

    Big Government is neither good nor bad, it simply is. Some problems can be most effectively solved by Government intervention. Some problems are best solved by markets. Our political system tries to enforce a false dichotomy simply to give identity to opposing factions, which every day forces us to make tradeoffs that we shouldn't have to.

    I want to make fewer of those tradeoffs, so I voted for Obama last week.

It's possible to throw as many screens and lights as you can afford on a stage, but for a concert experience all that matters is how the tech is used. In this case, the artist's vision is directly responsible for the design, programming, and implementation of the effects... and that makes all the difference.

    I can't imagine Toby Keith or Rascal Flatts disappearing into their basements for a week to design anything, let alone program and implement it themselves. Either way, I don't know of anyone else with Reznor's combination of technical and artistic chops, and that makes all the difference.

    Unfortunately, there's a difference between the 'fucking people over' represented by pirates who don't purchase the game and wouldn't even without available pirated copies, and the 'fucking people over' demonstrated when software developers intentionally cripple their product in ways that harm legitimate, paying users.

    I don't give a fuck about the pirates, they're not going to buy the game either way. If you sell me shitware with broken-ass 'copy protection', I'm going to be pissed, and I will do everything in my power to avoid purchasing your products in the future, because you have violated your implicit agreement to provide working software to paying customers.

    That is the issue. Copy protection, by definition, only inconveniences legitimate users, because the copy protection on any product worth purchasing will be cracked by a skilled hacker in a country with a bad enough exchange rate that it's more worth their time just to crack it. Do you really want to try to pass on your piracy 'losses' to legitimate users after they've purchased your product?

    I'm not sure how the parent got modded insightful, given the stunning misunderstanding of physics on display.

    Hydrogen fusion is non-renewable? Don't be daft, there's enough hydrogen in the ~1.3 billion cubic kilometers of Earth's oceans to generate the power output of the frickin' sun for ~750 years, roughly 8.0 x 10^34 joules.

    Conveniently enough, that's approximately 1.4 x 10^7 kJ of energy per kg of earthyness, so if you're running out of hydrogen, you're likely to have run into other more substantial air-conditioning problems along the way.

    Or, to put it in terms that anyone I'm arguing with is even less likely to understand, a couple orders of magnitude greater than the gravitational potential energy of... the Earth!

    If that isn't enough energy for something you have in mind, it's convenient that hydrogen is by far the most common element in the universe. Short of an incredible and implausible paradigm shift along the lines of exploiting zero-point energy or direct mass-energy conversion, fusion is where it's at.

    The entire point of a bluff/feint is that the cards are random, and calculating the exact probability of every possible hand has nothing to do with the actual hands that your opponents have. "My hand is better than 92% of the possible hands my opponent could have" is just enough to lose all of your chips 8% of the time.
