Comment: How is the delivery made? (Score 2) 188

I don't get this. What happens when the drone arrives at my address? Does it ring the doorbell and wait? Does it go round the back and leave it on the back porch if I'm out? (I'm in a low-crime neighbourhood where this is possible.) Or will it leave it with my neighbour, as instructed?

Experts: Aim of 2 Degrees Climate Goal Insufficient 427

from the keeping-it-cool dept.
An anonymous reader points out that a long held goal of keeping the Earth's average temperature from rising above 2 degrees Celsius might not be good enough. "A long-held benchmark for limiting global warming is 'utterly inadequate,' a leading U.N. climate scientist declared. Keeping the Earth's average temperature from rising past 2 degrees Celsius – a cap established by studies in the early 1970s – is far too loose a goal, Petra Tschakert, a professor at Penn State University and a lead author of an assessment report for the U.N.'s Intergovernmental Panel on Climate Change, or IPCC, said in a commentary published in the journal Climate Change Responses. Already, with an average increase of just 0.8 degrees Celsius, she wrote, 'negative impacts' are 'widespread across the globe.' Tschakert called for lowering the warming target to 1.5 degrees Celsius."

Scientists Create Permanently Slick Surface So Ketchup Won't Stay In Bottle 172

Posted by samzenpus
from the greased-lightning dept.
HughPickens.com writes Much of what we buy never makes it out of the container and is instead thrown away — up to a quarter of skin lotion, 16 percent of laundry detergent and 15 percent of condiments like mustard and ketchup. Now Kenneth Chang reports at the NYT that scientists have just solved one of life's little problems — how to get that last little bit of ketchup (or glue) out of a bottle. Using a coating that makes the inside of the bottle permanently wet and slippery, glue quickly slides to the nozzle or back down to the bottom. The technology could have major environmental payoffs by reducing waste. Superhydrophobic surfaces work similar to air hockey tables. Tiny peaks and valleys on the surface create a thin layer of air between the liquid and the coating. The air decreases friction, so the liquid almost levitates above the surface, just like the hockey puck floats above the table. LiquiGlide's approach is similar, but it uses a liquid lubricant, not a gas. "What could be a solution that provides sort of universal slipperiness?" says Dr. Varanasi. "The idea we had was, Why not think about trapping a liquid in these features?" Dr. Varanasi and Mr. Smith worked out a theory to predict interactions among the surface, the lubricant and air. Essentially, the lubricant binds more strongly to the textured surface than to the liquid, and that allows the liquid to slide on a layer of lubricant instead of being pinned against the surface, and the textured surface keeps the lubricant from slipping out. "We're not defying physics, but effectively, we are," says Smith.

Indian Supreme Court Strikes Down Law Against Posting 'Offensive' Content Online 54

palemantle writes: The Indian Supreme Court has overturned the controversial Section 66A of the IT Act which included a provision for a three-year jail term for sending "offensive" messages through a "computer resource or a communication device." In its judgement, the Supreme Court held "liberty of thought and expression as cardinal" and overturned the provision (66A) deeming it "unconstitutional." It's been in the news recently for an incident involving the arrest of a high school student for posting allegedly "offensive" content on Facebook about a local politician.

Child Psychotherapist: Easy and Constant Access To the Internet Is Harming Kids 353

Posted by samzenpus
from the there's-something-wrong-with-my-brain dept.
First time accepted submitter sharkbiter sends note that one of the UK's foremost psychotherapists has concerns that smartphones may be harmful to the mental health of children. "Julie Lynn Evans has been a child psychotherapist for 25 years, working in hospitals, schools and with families, and she says she has never been so busy. 'In the 1990s, I would have had one or two attempted suicides a year – mainly teenaged girls taking overdoses, the things that don't get reported. Now, I could have as many as four a month.'.... Issues such as cyber-bullying are, of course, nothing new, and schools now all strive to develop robust policies to tackle them, but Lynn Evans’ target is both more precise and more general. She is pointing a finger of accusation at the smartphones - “pocket rockets” as she calls them – which are now routinely in the hands of over 80 per cent of secondary school age children. Their arrival has been, she notes, a key change since 2010. 'It’s a simplistic view, but I think it is the ubiquity of broadband and smartphones that has changed the pace and the power and the drama of mental illness in young people.'”

FTC's Internal Memo On Google Teaches Companies a Terrible Lesson 121

Posted by samzenpus
from the I've-learned-nothing dept.
schwit1 writes FTC staffers spent enormous time pouring through Google's business practices and documents as well as interviewing executives and rivals. They came to the conclusion that Google was acting in anti-competitive ways, such as restricting advertisers from working with rival search engines. But commissioners balked at the prospect of a lengthy and protracted legal fight. For a big company, that process may have been enlightening. Agency staffers might find evidence of anti-competitive behavior. But that doesn't mean the firm will face the music in the end. Previous attempts to go after big companies — such as the Justice Department's long-running antitrust case against Microsoft in the 1990s — loomed large in regulators' minds at the time of the Google probe, according to a former official who worked at the agency then. "Even if we were in the right and could win," said the former official, "it could take a lot of resources away from other enforcement."

We have a lot of XML publishing workflows. MySQL provides a -X commandline option which returns the results of a query in XML. I don't know if PostgreSQL, MSSQL, or Oracle have the equivalent (perhaps someone who knows can post). Right now, it's a pain-free way to get what we need in the form we want, with zero additional effort. If it exists in other rDBMSs, that makes our choices wider.
