I'm sorry but the evidence just does not bear out your views at all. There is no compelling evidence that warm temperatures are bad for battery chemistry, in fact under laboratory tests the batteries last longer with fast charging and warm temperatures.

Go look at evtv.me. Those guys actually do the experiments.

The myth that nissan leafs have problems with warm temperatures is still not backed up by anything except for whining.

Texas Town Turns To Treated Sewage For Drinking Water 242

Scientific American reports that Wichita Falls, Texas has taken an unusual step, precipitated by the years-long drought that Texas has faced: it's using treated sewage for drinking water. From the article: To launch what it calls its "Direct Potable Reuse Project," the city pipes water 12 miles from its wastewater treatment plant to this treatment facility where it goes through microfiltration. A pump pulls water through a module filled with fibers that removes most of the impurities. Then it is forced through a semi-permeable membrane that can remove dissolved salts and other contaminants. The process, called reverse osmosis, is used by the U.S. military, in ships and in the manufacture of silicon chips. The water then gets blended with lake water before going through the regular water treatment system. ... At 60 cents per 1,000 gallons, it's far cheaper than any other source of water, [Wichita Falls' public works director Russell] Schreiber said. ... He said there have been few complaints so far. A glass of the finished product, sampled at a downtown restaurant, tasted about average for West Texas.

Almost right.

It's not about taxes, it's about spending.

Because when they spend, they'll come up with the money one way or another, indebt future generations, print money, sell government power.

But then again, take away the power to spend and you have a solution.

Or even better, just take away their power.

Train Derailment Dumps Two 737 Fuselages Into Clark Fork River 187

McGruber (1417641) writes "Boeing builds its 737 airplane fuselages in a Wichita, Kansas factory. The fuselages are then shipped on top of railroad flatcars (as shown in this photograph) to Boeing's Renton, Washington plant, where assembly is completed. Unfortunately, a train carrying two fuselages to Renton derailed approximately 18 miles east of Superior, Montana. The 737s slid down a steep embankment and ended up in the Clark Fork River. That'll buff right out."

Researchers Create Walking, Muscle-Powered Biobots 33

Zothecula writes If you're going to deploy robots in biological settings – for example, inside the body – it makes a lot of sense to build those robots out of actual biological body parts. Muscle, for example, is a very effective, biodegradable replacement for an electric actuator that can run in a nutrient-rich fluid without the need for any other power source. Bio-robotics experts in Illinois have demonstrated a bio-bot built from 3-D printed hydrogel and spinal muscle tissue that can "walk" in response to an electrical signal. Their next step will be trying to incorporate neurons that can get the bot walking in different directions when faced with different stimuli.

'Vampire' Squirrel Has World's Fluffiest Tail 54

sciencehabit (1205606) writes Few scientists have ever seen the rare tufted ground squirrel (Rheithrosciurus macrotis), which hides in the hilly forests of Borneo, but it is an odd beast. It's twice the size of most tree squirrels, and it reputedly has a taste for blood. Now, motion-controlled cameras have revealed another curious fact. The 35-centimeter-long rodent has the bushiest tail of any mammal compared with its body size.

The last time this came up in a big way, no one here could point to anything suggesting that flight is a necessary part of modern life, to the point that it is a constitutional right.

In fact, most people pointed to cases where travel was NOT a constitutional right.

So what will change is everyone here will now have a case to point to suggesting that the no-fly list is actually unconstitutional. Actually unconstitutional as opposed to obviously unconstitutional.

So the difference on slashdot is that people will have a case to point to, but still won't.

What the fuck?

Have you ever read the constitution?

First of all you have it all backwards my retarded son.

The constitution allows the federal government to be granted certain rights by the people to do some very specific things. The federal government is PROHIBITED from doing anything not specifically listed.

I quoteth:

Tenth Amendment
The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people.

Please for the love of the spaghetti monster, where in the constitution is the federal government given the power to restrict people's travel liberties without due process? Oh that's right, it ain't there so they don't have it.

Fifth Amendment
No person shall be held to answer for a capital, or otherwise infamous crime, unless on a presentment or indictment of a Grand Jury, except in cases arising in the land or naval forces, or in the Militia, when in actual service in time of War or public danger; nor shall any person be subject for the same offence to be twice put in jeopardy of life or limb; nor shall be compelled in any criminal case to be a witness against himself, nor be deprived of life, liberty, or property, without due process of law; nor shall private property be taken for public use, without just compensation.

Oh and the constitution does not have to list every right that belongs to the people. They belong to the people, listed on a piece of paper or not and are not granted by the government. The government is granted it's rights by the people, not the other way around.

Ninth Amendment
The enumeration in the Constitution, of certain rights, shall not be construed to deny or disparage others retained by the people.

So to the parent post and those who modded it up: SuuuUUUuuuck IiiiiiiiT.

Comment Some newer coins intend to stay ASIC resistant (Score 2) 281

While the threat of a 51% attack may be blown out of proportion (a pool sells their cut of the coins that are mined and it is in their best interest that the coin remain as valuable as possible - attacking a coin would be counterproductive), some altcoin developers have stated that they will change their coin's proof-of-work algorithm if ASICs are developed for it. Vertcoin and Execoin's developers have both stated they'll do whatever it takes to keep ASICs out.

Most of the speculation that fuels the pump-and-dump world of altcoins is based on the belief that Bitcoin may not end up being the cryptocoin that average people use to buy pizza, pay their bills, etc.

Amazon's 3D Smartphone As a (Useful) Gimmick 68

Steve Patterson (2850575) writes It's rumored that Amazon will launch its own 3D smartphone on June 18. While it may be compelling, a sexy 3D feature won't catapult Amazon into the lead of the cut-throat smartphone category. If this were true, the EVO 3D, introduced two years ago by HTC and the W960, introduced by Samsung four years ago, would have been top sellers rather than niche products. However, a smartphone that renders 3D images does present an internet retailing opportunity for Amazon. It would be useful to Amazon in selling tangible consumer merchandise, just like Amazon's Kindle Fire tablet was designed to improve Amazon's merchandising of ebooks and video streaming products. What else would you like to use a 3D phone for?

Comment Re:Key Point Missing (Score 2) 34

The summary misses a key point. Yes they scan and store the entire book, but they are _NOT_ making the entire book available to everyone. For the most part they are just making it searchable.

Agreed that it's not in the summary, but as you correctly note, it's just a "summary". Anyone who reads the underlying blog post will read this among the facts on which the court based its opinion: "The public was allowed to search by keyword. The search results showed only the page numbers for the search term and the number of times it appeared; none of the text was visible."

So those readers who RTFA will be in the know.

Submission + - Appeals Court finds scanning to be fair use in Authors Guild v Hathitrust

NewYorkCountryLawyer writes: In Authors Guild v Hathitrust, the US Court of Appeals for the Second Circuit has found that scanning whole books and making them searchable for research use is a fair use. In reaching its conclusion, the 3-judge panel reasoned, in its 34-page opinion (PDF), that the creation of a searchable, full text database is a "quintessentially transformative use", that it was "reasonably necessary" to make use of the entire works, that maintaining maintain 4 copies of the database was reasonably necessary as well, and that the research library did not impair the market for the originals. Needless to say, this ruling augurs well for Google in Authors Guild v. Google, which likewise involves full text scanning of whole books for research.

Isn't the chargeback potential a risk under paypal not found for bitcoin? When someone gets paid the charge can be reversed at any time per Paypal's discretion. Thieves will buy bitcoins all the time on ebay with stolen paypal accounts and than the seller will be out all the money when paypal reverses the transaction. Additionally, isn't paypals security polices also a risk for the user unlike with bitcoin where you can trust the mathematics and network which is immune from many traditional attack vectors?

Yes, chargebacks are a potential fraud risk for business owners. As a customer, though, being able to perform a chargeback is an important safeguard against a seller that doesn't make good on their part of a transaction.

While having your bank/credit card information on file at PayPal is also a potential security risk, it's still significantly less of a risk than trusting every business you allow to directly process your credit card.

Comment Almost, but not quite (Score 1) 117

Bitcoin does solve the issue of being able to electronically pay people you may not trust, but so does PayPal. Bitcoin transactions are slow to confirm, you have no protection as a buyer to perform a chargeback (for example, you buy tickets for a concert that turn out to be counterfeit) and the price of Bitcoin is extremely unstable. Bitcoin also is not really free of transaction fees, either. You will pay a fee to an exchange when buying Bitcoin with fiat.

Bitcoin's deflationary design also makes it lousy as a currency, since why would you use it to buy two pizzas today when that same amount a few years from now might buy you a Tesla Model S?

Cryptocurrency probably does have a place in the future of commerce, but it will probably be something that addresses Bitcoin's serious shortcomings.
