First Ultraviolet Quantum Dots Shine In an LED 17

ckwu with word that South Korean researchers have created the first UV-emitting quantum dots, and employed them in the creation of a flexible LED. Their achievement is notable because no one has previously succeeded in making quantum dots capable of emitting light at wavelengths shorter than 400 nm, which defines the upper range of the UV spectrum. Writes ckwu: To get quantum dots that emit UV, the researchers figured out how make them with light-emitting cores smaller than 3 nm in diameter. They did it by coating a light-emitting cadmium zinc selenide nanoparticle with a zinc sulfide shell, which caused the core to shrink to 2.5 nm. The quantum dots give off true UV light, at 377 nm. An LED made with the quantum dots could illuminate the anticounterfeiting marks on a paper bill. The article names a few applications of the technology, besides, including water sterilization and industrial applications.

He blames employee lawsuits after a layoff in 2013, the French labor laws and the courts. "Those court decisions forced the company to announce bankruptcy," he said.

In a blog update on their site, they responded saying in part "There has recently been some report that the GIMP-Win project on SourceForge has been hijacked; this project was actually abandoned over 18 months ago, and SourceForge has stepped-in to keep this project current.

So how can I get a smartphone if I'm outside of AT&T's market?

Smartphones on other networks are A. phones for which the carrier imposes a similar requirement of a data plan or B. phones comparable in functionality to an AT&T smartphone.

But in your example, why would I buy a phone from AT&T if I'm going to get a GoPhone sim?

To ensure that it works on AT&T's network. (GoPhone is AT&T's prepaid brand.)

Won't I be paying for two phone plans then? AT&T (unused, but still per month costs) and GoWhatever?

Phones for use with GoPhone are sold up front.

If you are talking something like teachers the ones I know that have done this fulfill their obligations with completing the school year as opposed to the physical year.

Structural unemployment means the labor surplus associated with widespread layoffs in an industry. You're referring to seasonal unemployment, which is generally excluded from structural unemployment. Structural unemployment happens on cycles far longer than a year or is permanent. How is someone supposed to work off student loan debt if he comes to find that nobody is hiring in his location and field?

It also means that if we got a Congress that actually wanted to retroactively shorten copyright terms they can.

I wouldn't be so sure of that. Major copyright owners would consider a term reduction to be "private property be[ing] taken for public use, without just compensation" per the Fifth Amendment to the US Constitution (and foreign counterparts) and sue the government for said "just compensation".

What the heck is a feature phone anyways?

A smartphone is a phone for which AT&T will automatically add on a data plan unless you use obscure means to prevent it, such as buying a GoPhone SIM and activating it over the Internet. A feature phone is a cell phone that is not a smartphone.

Hmm, let's see. The Soviet programs were cancelled in '72 according to you (actually that's not quite right but it's close enough). When was the last mission to the Moon? Oh that's right, December 1972. Quite a coincidence that...

Pretty much, yeah it's a coincidence. Either way, your original claim as to the order and connection of events is incorrect.


Feds Bust a Dark-Web Counterfeit Coupon Kingpin 86

Sparrowvsrevolution writes: The dark web has become the go-to corner of the Internet to buy drugs, stolen financial data, guns...and counterfeit coupons for Clif bars and condoms? The FBI indicted Beauregard Wattigney yesterday for wire fraud and trademark counterfeiting on digital black market sites Silk Road and Silk Road 2. Wattigney allegedly spoofed coupons for dozens of products and sold collections of them online in exchange for Bitcoin. The FBI accused him of doing $1 million worth of collective damage to the companies he made coupons for, but a fraud consultancy believes the total financial cost of his actions was much higher. Wattigney also offered expensive lessons that taught people how to make their own coupons. "In his tutorials, [he] explained the simple breakdown of barcode creation using the increasingly universal GS1 standard: GS1 codes begin with a 'company prefix' that can be copied from any of the company's products. The next six digits are the 'offer code,' which can be any random number for a counterfeit coupon, followed by the savings amount listed in cents and the required number of item purchases necessary to receive the discount."

There are a couple of problems with your theory, though it could play out that way. Right now the smaller vendors are often more efficient than the larger ones. Smaller players can be more nimble.

Second the larger players all have vastly different models. Just to pick a few examples of the bigger players
AWS -- Generic low quality server experience offered cheaply. Walmart
Sungard -- Highly custom environments quality management lots of value added labor
Verizon (was Terremark) -- Moderately custom environments, mix of high performance cloud IaaS and colo. Some value added services with strong partner service model.
Oracle -- Unified cloud stack offering IaaS plus advanced management especially knowledge of Oracle applications
Azure -- IaaS with Microsoft based PaaS. Good pricing on SQL Server.

How do those consolidate? I think we are looking at a situation more like clothing where stores are genuinely different fulfilling niches for various customers.

The crossover between tricky to move is much lower than the crossover for better to run your own datacenter. Not necessarily the case though for better to run your own cloud out of someone else's colo or better to jointly administer a cloud with a colo provider. So this can happen. The cost of multiple good quality data centers is very very high compared to the cost of getting data out of one.

As far as GP's post. He's wrong. First off clouds are designed to scale so adding another copy of parts of the data for replication is not hard. Second you can do crossover networking from one data center to another if you need to move and the cost of using the cloud provider's bandwidth is too high. Also there are devices that can be physically connected to the racks and then trucked (think backup drive moving physically but 20-100x scale). Mainly a data move is the sort of thing an agent can coordinate easily.

That's not what's happening, they are buying more servers. The types of computational workloads are also shifting during the cloud migrations. The savings are coming from: staffing efficiencies, reduced real estate costs, reduced power costs, reductions in physical security, savings in the procurement process...
