Nvidia Is About To Steal The Cryptocurrency Mining Crown …

Posted: August 8, 2015 at 7:20 pm

Buried on the 17th page of Toms Hardwares GeForce GTX 750 Ti graphics card review is a simple benchmark result that will dramatically disrupt the landscape of cryptocurrency mining. In fact, its the kind of data that should send AMD back to the drawing board at least if they want to maintain their choke-hold on the mining hardware market.

Historically AMD has been the undisputed crowd favorite of miners looking to stock up on new forms of digital currency like Dogecoin and Litecoin. AMDs Radeon graphics cards possess a secret sauce that allows significantly more powerful compute capabilities, at least the kind required for Scrypt-based mining.

That is, untilNvidiareleased their new Maxwell architecture this week.

As we learned from my introduction to the GTX 750 Ti,first-generation Maxwell cards exhibit a 35% peak performance boost per core and twice the performance per watt. They also blow Kepler hashrates out of the water. Based on what Im seeing with the 750 Ti, Nvidia is poised to embarrass AMD in the performance-per-watt race and thats a substantial factor when youre paying the inflated energy bills caused by mining.

Nvidia didnt breathe a word of Maxwells seriously improved hashing ability in their marketing copy or press briefings, but Toms Hardware discovered it, and Ive been able to replicate their findings with multiple 750 Ti cards from both Nvidia and PNY.

Hashrate using a reference 750 Ti 1GB card from Nvidia (Software: Cudaminer)

What youre looking at in the image above is a hashrate of about 242kh/s using Nvidias reference 750 Ti 1GB graphics card ($139). This is significant for several reasons. First, the 750 Ti is a 60Watt card and doesnt even require a PCI-E power connector. You could plug this card into a cheap box from HP or Dell with a 300W power supply and have power to spare. Second, the temperature never seems to breach 65 degrees Celsius, and it runs considerably quieter and cooler than the AMD 260x ($119), which achieves a peak hashrate of 206kh/s and consumes nearly 130Watts of power.

Hold on a minute! I can hear you saying. AMDs 260x is $20 cheaper than Nvidias entry-level 750 Ti! Thats true, but the nominal price difference quickly evaporates when you consider how the 750 Ti sips power, which matters in the long run. Additionally, Toms Hardware ran the same mining environment test with AMDs upcoming Radeon 265 ($149) and achieved a peak hashrate of 252kh/s and remember that the Radeon 265 is a 150Watt card.

For that same price of $149, heres what I pulled off with PNYs 750 Ti 2GB with a moderate (and stable) overclock:

Liberty House – 207 Photos – American (New) – Jersey City …

Posted: at 7:19 pm

I was here last night for dinner, with 3 girlfriends. We made a reservation weeks prior, simply due to the fact that it's the holiday season and we figured it would be busy!

Once we walked in, we were greeted by the hostess, she showed us to our table and gave us the drink menu. Within 5 minutes we were introduced to our waiter, he took our drink order, told us the specials and left us with menus.

Being that this was all of our first times here we order a little bit of everything. For starters, drinks, obviously the most important, 3 cosmos and an extra dirty martini, all super yummy, yet a tiny bit to strong. For appetizer we ordered the sushi special, which was average, I've had better sushi at a take out place. The sausage risotto, which had wayyyyyy to much blue cheese on it, the organic salad, just your plain old salad, and the calamari, which was actually perfectly cooked. For dinner, we ordered the hanger steak, short ribs and the cod special. Presentation was very nice portion size was decent, but in my opinion a little small considering the large price tag. Everything was fresh though! For dessert we ordered the apple strudel, which was alright, not the best I've had. All that for 4 people came to $238, my opinion, just a tad pricey!!!

The view is great, but, during the winter you can't really sit outside and enjoy the view, and to be honest, I'm not paying for the view, I'm paying for the food!

Service was great! Our server was clearly knowledgeable of the food he was serving which is great!

All in all, I would come back! Maybe during the summer so I can enjoy the view!

Bitcoin

Bitcoin is a decentralized digital currency that enables instant payments to anyone, anywhere in the world. Bitcoin uses peer-to-peer technology to operate with no central authority: transaction management and money issuance are carried out collectively by the network.

The original Bitcoin software by Satoshi Nakamoto was released under the MIT license. Most client software, derived or "from scratch", also use open source licensing.

Bitcoin is the first successful implementation of a distributed crypto-currency, described in part in 1998 by Wei Dai on the cypherpunks mailing list. Building upon the notion that money is any object, or any sort of record, accepted as payment for goods and services and repayment of debts in a given country or socio-economic context, Bitcoin is designed around the idea of using cryptography to control the creation and transfer of money, rather than relying on central authorities.

Interactives . DNA . Genetic Engineering

Posted: at 1:42 pm

Genetic engineering is the process of removing a gene from one organism and putting it into another. Often, the removed genes are put into bacteria or yeast cells so that scientists can study the gene or the protein it produces more easily. Sometimes, genes are put into a plant or an animal.

One of the first genetic engineering advances involved the hormone insulin. Diabetes, a medical condition that affects millions of people, prevents the body from producing enough insulin necessary for cells to properly absorb sugar. Diabetics used to be treated with supplementary insulin isolated from pigs or cows. Although this insulin is very similar to human insulin, it is not identical. Bovine insulin is antigenic in humans. Antibodies produced against it would gradually destroy its efficacy.

Scientists got around the problem by putting the gene for human insulin into bacteria. The bacteria's cellular machinery, which is identical to the cellular machinery of all living things, "reads" the gene, and turns it into a protein-human insulin-through a process called translation.

DRD4 genotype predicts longevity in mouse and human.

Posted: at 1:41 pm

Longevity is influenced by genetic and environmental factors. The brain's dopamine system may be particularly relevant, since it modulates traits (e.g., sensitivity to reward, incentive motivation, sustained effort) that impact behavioral responses to the environment. In particular, the dopamine D4 receptor (DRD4) has been shown to moderate the impact of environments on behavior and health. We tested the hypothesis that the DRD4 gene influences longevity and that its impact is mediated through environmental effects. Surviving participants of a 30-year-old population-based health survey (N = 310; age range, 90-109 years; the 90+ Study) were genotyped/resequenced at the DRD4 gene and compared with a European ancestry-matched younger population (N = 2902; age range, 7-45 years). We found that the oldest-old population had a 66% increase in individuals carrying the DRD4 7R allele relative to the younger sample (p = 3.5 10(-9)), and that this genotype was strongly correlated with increased levels of physical activity. Consistent with these results, DRD4 knock-out mice, when compared with wild-type and heterozygous mice, displayed a 7-9.7% decrease in lifespan, reduced spontaneous locomotor activity, and no lifespan increase when reared in an enriched environment. These results support the hypothesis that DRD4 gene variants contribute to longevity in humans and in mice, and suggest that this effect is mediated by shaping behavioral responses to the environment.

Rash 101: The Most Common Types of Skin Rashes

Posted: at 1:41 pm

Rash facts Rash is not a specific diagnosis. Instead it means skin inflammation and discoloration that changes the way the skin looks. Common rashes include eczema, poison ivy, hives, and heat rash. Infections that cause rashes may be fungal, bacterial, parasitic, or viral. Over-the-counter products may be helpful treatments for many skin rashes. Rashes lasting more than a few days that are unexplained should be evaluated by a doctor. What are the causes, symptoms, and signs of common noninfectious rashes?

Some common, noninfectious rashes are listed below. If you have a new rash and you have a fever or some other generalized illness associated with it, it would be best to see your doctor.

Seborrheic dermatitis: Seborrheic dermatitis is the single most common rash affecting adults. It produces a red scaling eruption that characteristically affects the scalp, forehead, brows, cheeks, and external ears.

Atopic dermatitis: Atopic dermatitis, often called eczema, is a common disorder of childhood which produces red itchy, weeping rashes on the inner aspects of the elbows and in back of the knees as well as the cheeks, neck, wrists, and ankles. It is commonly found in patients who also have asthma and hay fever.

Contact dermatitis: Contact dermatitis is a rash that is brought on either by contact with a specific chemical to which the patient is uniquely allergic or with a substance that directly irritates the skin. Some chemicals are both irritants and allergens. This rash is also occasionally weepy and oozy and affects the parts of the skin which have come in direct contact with the offending substance. Common examples of contact dermatitis caused by allergy are poison ivy or poison oak (same chemical, different plant) and reactions to costume jewelry containing nickel.

Diaper rash: This is a common type of contact dermatitis that occurs in most infants who wear diapers when feces and urine are in contact with skin for too long.

Stasis dermatitis: This is a weepy, oozy dermatitis that occurs on the lower legs of individuals who have chronic swelling because of poor circulation in veins.

Psoriasis: This bumpy scaling eruption never weeps or oozes and tends to occur on the scalp, elbows, and knees. It leads to silvery flakes of skin that scale and fall off.

Nummular eczema: This is a weepy, oozy dermatitis that tends to occur as coin-shaped plaques in the wintertime and is associated with very dry skin.

Drug eruptions: Certain drugs can produce skin rash as an unwanted side effect. The common appearance is similar to rashes produced by certain common viral infections. On the other hand, drugs may produce a wide variety of other types of rashes.

The Connection Has Been Reset – The Atlantic

Illustration by John Ritter

Many foreigners who come to China for the Olympics will use the Internet to tell people back home what they have seen and to check what else has happened in the world.

The first thing theyll probably notice is that Chinas Internet seems slow. Partly this is because of congestion in Chinas internal networks, which affects domestic and international transmissions alike. Partly it is because even electrons take a detectable period of time to travel beneath the Pacific Ocean to servers in America and back again; the trip to and from Europe is even longer, because that goes through America, too. And partly it is because of the delaying cycles imposed by Chinas system that monitors what people are looking for on the Internet, especially when theyre looking overseas. Thats what foreigners have heard about.

Theyll likely be surprised, then, to notice that Chinas Internet seems surprisingly free and uncontrolled. Can they search for information about Tibet independence or Tiananmen shooting or other terms they have heard are taboo? Probablyand theyll be able to click right through to the controversial sites. Even if they enter the Chinese-language term for democracy in China, theyll probably get results. What about Wikipedia, famously off-limits to users in China? They will probably be able to reach it. Naturally the visitors will wonder: Whats all this Ive heard about the Great Firewall and Chinas tight limits on the Internet?

In reality, what the Olympic-era visitors will be discovering is not the absence of Chinas electronic control but its new refinementand a special Potemkin-style unfettered access that will be set up just for them, and just for the length of their stay. According to engineers I have spoken with at two tech organizations in China, the government bodies in charge of censoring the Internet have told them to get ready to unblock access from a list of specific Internet Protocol (IP) addressescertain Internet cafs, access jacks in hotel rooms and conference centers where foreigners are expected to work or stay during the Olympic Games. (I am not giving names or identifying details of any Chinese citizens with whom I have discussed this topic, because they risk financial or criminal punishment for criticizing the system or even disclosing how it works. Also, I have not gone to Chinese government agencies for their side of the story, because the very existence of Internet controls is almost never discussed in public here, apart from vague statements about the importance of keeping online information wholesome.)

Depending on how you look at it, the Chinese governments attempt to rein in the Internet is crude and slapdash or ingenious and well crafted. When American technologists write about the control system, they tend to emphasize its limits. When Chinese citizens discuss itat least with methey tend to emphasize its strength. All of them are right, which makes the governments approach to the Internet a nice proxy for its larger attempt to control peoples daily lives.

Disappointingly, Great Firewall is not really the right term for the Chinese governments overall control strategy. China has indeed erected a firewalla barrier to keep its Internet users from dealing easily with the outside worldbut that is only one part of a larger, complex structure of monitoring and censorship. The official name for the entire approach, which is ostensibly a way to keep hackers and other rogue elements from harming Chinese Internet users, is the Golden Shield Project. Since that term is too creepy to bear repeating, Ill use the control system for the overall strategy, which includes the Great Firewall of China, or GFW, as the means of screening contact with other countries.

In America, the Internet was originally designed to be free of choke points, so that each packet of information could be routed quickly around any temporary obstruction. In China, the Internet came with choke points built in. Even now, virtually all Internet contact between China and the rest of the world is routed through a very small number of fiber-optic cables that enter the country at one of three points: the Beijing-Qingdao-Tianjin area in the north, where cables come in from Japan; Shanghai on the central coast, where they also come from Japan; and Guangzhou in the south, where they come from Hong Kong. (A few places in China have Internet service via satellite, but that is both expensive and slow. Other lines run across Central Asia to Russia but carry little traffic.) In late 2006, Internet users in China were reminded just how important these choke points are when a seabed earthquake near Taiwan cut some major cables serving the country. It took months before international transmissions to and from most of China regained even their pre-quake speed, such as it was.

Thus Chinese authorities can easily do something that would be harder in most developed countries: physically monitor all traffic into or out of the country. They do so by installing at each of these few international gateways a device called a tapper or network sniffer, which can mirror every packet of data going in or out. This involves mirroring in both a figurative and a literal sense. Mirroring is the term for normal copying or backup operations, and in this case real though extremely small mirrors are employed. Information travels along fiber-optic cables as little pulses of light, and as these travel through the Chinese gateway routers, numerous tiny mirrors bounce reflections of them to a separate set of Golden Shield computers.Here the terms creepiness is appropriate. As the other routers and servers (short for file servers, which are essentially very large-capacity computers) that make up the Internet do their best to get the packet where its supposed to go, Chinas own surveillance computers are looking over the same information to see whether it should be stopped.
