Disagree about peak efficiency. In my experience testing PSUs, it is normally found around 90% load. Newer PSUs have gotten a lot better and enhancing efficiency at lower load levels, but PSUs still work most efficiently when running near the load they are designed for.
Newegg's calculator is a joke. It drastically overestimates requirements so they can pimp massive PSUs with higher profit margins. I suggest adding up the various component manufacturer specifications (i.e. max power draw of the MB, GPU(s), HDD(s), DIMM(s), and CPU(s)) and throw in 10-15 W for overhead, then buy a decent PSU with a load rated as close to that number as you can get. Even with a dual GPU setup, you are VERY unlikely to exceed 400W of DC power draw. My current mid-range single GPU system draws around 200W under load (gaming).
I used to test server and PC power supplies for a living (until 2009). I do NOT recommend running at 50% load unless your PSU is a cheap turd and you are worried (rightfully so) about component failure. 80-90% load will give you better efficiency, a higher power factor, and less harmonics. Fyi, as a residential electricity customer you don't really have to worry about power factor or harmonics much but large companies can be charged by the utilities for abusing the infrastructure with a ton of shitty/under-utilized PSUs. Since the company I used to work for sold into enterprise, we were very interested in PSU performance and matching up components for efficiency.
At home, I run a decent 350W PSU now, and my system draws about 200W of DC power under load (i.e. gaming) with my components (single Intel 2500K CPU, 8GB RAM, ATI 7870 GPU. 1 HDD and 1 SSD) and around 130W when surfing the web or working. I literally couldn't find a decent, well priced PSU with lower DC power output when I built the machine 18 months ago. It cracks me up when I see guys putting 700W power supplies into their gaming rigs that never draw more than 300W (and none seem to understand the difference between AC power draw from the wall and DC power draw of the components in their system, which is what the PSUs are rated for). It's basically flushing money down the toilet in multiple ways.
Or so I thought. In 2007 they sent me two DMCA notices and shut off my internet twice in one week. The second time they said "if it happens again, we will revoke your account." I said go for it. I can always get high speed internet from one of the other 4 providers available at my house. I kept downloading and never heard from them again.
To me, the lesson of the story is that the ISPs are willing to hassle their infringing customers to the point of making their service slightly inconvenient, but as soon as you threaten to take away their $40/month, they back down.
It is only at historically low levels if you look at the "official" numbers which report ~2% inflation. If you look at CPI inflation, which takes gas, food, and the things that normal people actually buy (vs multi-millionaires' investments and employee salaries) into consideration, inflation is currently around 6% and has spiked over 10% during the last 4-5 years.
It's not a pretty picture and a topic that the federal reserve and politicians (other than a few independents) have been avoiding like the plague. As someone that drives V-8 (well mostly ride a motorcycle now because gas is so expensive) and worked in grocery stores for years, I am particularly sensitive to price increases in those areas and they have been pretty intense.
Don't be fooled by government statistics, just take a picture of 100 random items in a grocery store this week and check again in a year. Even with all the government subsidies on our food, they will average much more than a 2% increase in twelve months.
Sorry, but judging things is a fundamental human right. This is something that I have found largely misunderstood by my Chinese friends. They will say things like "There is no difference between the US government and the Chinese government, both are corrupt." While I agree with the corruption (although it is a much more straightforward sort in China), I think they miss a key element in the United States, i.e. we enjoy certain inalienable rights that they don't understand the benefit of, largely because they have never had them.
Americans, and really everyone in western style democracies are free to criticize and judge any government, religion, or belief they want to in a public forum. This is freedom of speech and it is the most important right we have.
I don't think your statement is accurate about uninsured cancer patients. My roommate is a cardiologist (obviously he doesn't treat cancer patients very often but I believe this still applies) and he is adamant that patients in the current system (at least at UCSD medical center in San Diego, a very nice hospital system) receive the same care independent of their insurance status. It may destroy the patients finances and force them into bankruptcy, but not having health insurance doesn't mean hospitals won't treat you. Now if a cancer patient doesn't have insurance, and doesn't want to lose their house for their treatment, they may choose to go the painkiller route (having seen friends and family go through cancer treatment, this is the route I would likely choose), but they can certainly choose to bury themselves in debt before they die if they want too.
I think the "non-treatment" fallacy is a big mis-truth that supporters of public healthcare covet and really don't understand... Just because you don't have insurance doesn't mean you won't be treated for your problem. In my limited experience, the quality of care is more dependent on the facility than whether or not the patent is insured. And in many cases, uninsured patients may actually pay less due to their financial situation than an insured patients pays for a deductible.
Since this post is getting long I might as well say that I think lawyers are the problem, not privatized healthcare. Something like 50% of the private practice expenses go to malpractice insurance, hospitals pay an amazing amount of money towards it as well. Limiting the amount of money people could sue hospitals and doctors for (say $500,000 or something more more reasonable than the current infinity dollars) would go a long way to reducing the cost of health care and insurance. Unfortunately the lawyers that litigate those cases hold a lot of sway in the US political system. They are chomping at the bit to start suing the government backed/regulated/mandated insurance schemes that are coming into effect with obamacare.
Hahaha. Well US History wasn't my area of focus.. I guess I should have clarified that I approve of the message put forth in the last sentence of the parent post. People in this country can't even look back 15 years to recognize a cyclical pattern, much less 400...
While I largely agree with Dawkins views toward religion, I don't know if the The Good News Club is as bad as he makes it out to be. Their website says "In 2001 the U.S. Supreme Court ruled in Good News Clubs v. Milford Central School that Good News Clubs can meet in public schools in the United States after school hours on the same terms as other community groups. Children attend Good News Club only with their parents' permission."
So, it happens after school (Dawkins says "after the bell rings" implying during class hours but he must be referring to the last bell of the day) and parents must give permission. I don't see how this would impact anyone's kids unless they wanted them to go. I had also never heard of that organization until today.
Clearly though, Dawkins is wording things to skew the/. crowd. I also feel like he is using his personal war against Christianity/religion to elevate his status and inflate a big ego (notice the name of his organization and the URL that he wants to other organizations to redirect too). Listening to him talk, I can't help but be reminded of.... RELIGIOUS PEOPLE. It's like he wants to be Science's Jesus Christ.
Wtf are you talking about??? I have several micro-USB devices and bad eyesight. I've never been able to insert one upside down or break one.
Apple is being a dick because they are using a proprietary connector. Period. If they really wanted to use something different than micro-usb and get my approval, they should just standardize the fucking plug so accessory manufacturers don't have to pay a license fee and more than just idevices can use it!
Shit like this holds us back. Just like the silly patent wars. Apple is using a stellar legal department and small steps of innovation to put profit before anything else. Am I the only one that finds it totally fucking stifling to force users into proprietary everything? Jesus dude, I'm all worked up now...
Not all calories are the same, and surveys are self reported. There are so many potentially major problems with those two facts that the survey's result and any conclusions/theories about BPA are moot.
How many people do you know that have tried heroin and not gotten addicted? How many people do you know that have been "prescribed" heroin? I can think of one person, a roommate I had in college that got violently ill after trying heroin and never did it again. I also know several people that have gone the other route, tried the stuff, loved it, and had sustained heroin addictions for at least a couple months before weaning off. That or they never quit and are now either dead or lost to me. In my experience, heroin addiction is remarkably similar to oxy addiction but is VASTLY different from cocaine (It's not an opiate!!!). The only drug I have seen that is more destructive than heroin/oxy (i.e. opiates) is meth. Meth is really really fucked up.
Seeing your buddy quit a "mild" oxy addiction cold turkey is enough to make someone never want to touch the stuff. It is brutal.
Seriously. I ride either a motorcycle or a SUV 30 miles to work every day. On very noticeable difference between vehicles, that never ceases to amaze me, is how someone will jump out of the way if they are going 70 MPH in the fast lane and I come up on them at 80MPH on my 400lb motorcycle. But if I'm in my 5000lb SUV and come up on them at 80MPH, they seem to enjoy slowing me down, sticking it out in that lane indefinitely even if the rest of the highway is near empty Even though I ride faster on the bike, but I don't have to go around people in the fast lane as much as the vehicle that weighs an order of magnitude more and is capable of causing a lot more damage to them.

A $15 propane tank is a lot smaller liability than a $10,000 battery pack.
I think the problem is more related to the use of catalytic converters and 4 stroke engines rather than public transportation.

Yup. And at 80% efficiency, 300W at the wall means the components are only pulling 240W of DC power...
