An anonymous reader quotes a report from The Independent: Continuous technological improvements have led to a rapid fall in the cost of renewable energy in recent years, meaning some forms can already comfortably compete with fossil fuels. The report suggests this trend will continue, and that by 2020 "all the renewable power generation technologies that are now in commercial use are expected to fall within the fossil fuel-fired cost range." Of those technologies, most will either be at the lower end of the cost range or actually undercutting fossil fuels. "This new dynamic signals a significant shift in the energy paradigm," said Adnan Amin, director-general of the International Renewable Energy Agency (IREA), which published the report. "Turning to renewables for new power generation is not simply an environmentally conscious decision, it is now -- overwhelmingly -- a smart economic one." The report looked specifically at the relative cost of new energy projects being commissioned. As renewable energy becomes cheaper, consumers will benefit from investment in green infrastructure. The current cost for fossil fuel power generation ranges from around 4p to 12p per kilowatt hour across G20 countries. By 2020, IREA predicted renewables will cost between 2p and 7p, with the best onshore wind and solar photovoltaic projects expected to deliver electricity by 2p or less next year.Read Replies (0)

The days may be numbered for the world's largest passenger aircraft. An anonymous reader shares a report: Airbus, the European aerospace group that makes the A380 superjumbo, said on Monday that it would have to end production of the plane if its only major customer, Emirates, did not order more (Editor's note: the link may be paywalled; alternative source). The admission by John Leahy, the company's chief operating officer, was the latest indication that Airbus miscalculated more than two decades ago when it bet that clogged runways would create demand for larger planes that could deliver more people with fewer landing slots. Instead, airlines bypassed the major hubs and ordered midsize planes that could fly directly between regional airports. [...] When Airbus started delivering the A380 a decade ago, after spending $25 billion to develop it, the company based near Toulouse, France, saw the plane as the solution to airport congestion and to increased demand for air travel. Only so many planes can land at an airport in any given day, so Airbus reasoned that planes carrying more people would allow airports to absorb more passengers. The A380 can carry more than 500 passengers while also offering amenities like showers, first-class suites and a bar.Read Replies (0)

An anonymous reader shares a report: Researchers Neil Gandal, JT Hamrick, Tyler Moore, and Tali Oberman have written a fascinating paper on Bitcoin price manipulation. Entitled "Price Manipulation in the Bitcoin Ecosystem" and appearing in the recent issue of the Journal of Monetary Economics the paper describes to what degree the Bitcoin ecosystem is controlled by bad actors. To many it's been obvious that the Bitcoin markets are, at the very least, being manipulated by one or two big players. "This paper identifies and analyzes the impact of suspicious trading activity on the Mt. Gox Bitcoin currency exchange, in which approximately 600,000 bitcoins (BTC) valued at $188 million were fraudulently acquired," the researchers wrote. "During both periods, the USD-BTC exchange rate rose by an average of four percent on days when suspicious trades took place, compared to a slight decline on days without suspicious activity. Based on rigorous analysis with extensive robustness checks, the paper demonstrates that the suspicious trading activity likely caused the unprecedented spike in the USD-BTC exchange rate in late 2013, when the rate jumped from around $150 to more than $1,000 in two months." The team found that many instances of price manipulation happened simply because the market was very thin for various cryptocurrencies including early Bitcoin.Read Replies (0)

Accurate location data is on smartphones, so why don't more wireless carriers use it to locate emergency callers? From a report, shared by a reader: Software on Apple's iPhones and Google's Android smartphones help mobile apps like Uber and Facebook to pinpoint a user's location, making it possible to order a car, check in at a local restaurant or receive targeted advertising. But 911, with a far more pressing purpose, is stuck in the past. U.S. regulators estimate as many as 10,000 lives could be saved each year if the 911 emergency dispatching system were able to get to callers one minute faster. Better technology would be especially helpful, regulators say, when a caller can't speak or identify his or her location. After years of pressure, wireless carriers and Silicon Valley companies are finally starting to work together to solve the problem. But progress has been slow. Roughly 80% of the 240 million calls to 911 each year are made using cellphones, according to a trade group that represents first responders. For landlines, the system shows a telephone's exact address. But it can register only an estimated location, sometimes hundreds of yards wide, from a cellphone call. That frustration is now a frequent source of tension during 911 calls, said Colleen Eyman, who oversees 911 services in Arvada, Colo., just outside Denver.Read Replies (0)

Lasrick shares "Don't fear the robopocalypse," an interview from the Bulletin of the Atomic Scientists with the former Army Ranger who led the team that established the U.S. Defense Department policy on autonomous weapons (and has written the upcoming book Army of None: Autonomous Weapons and the Future of War). Paul Scharre makes the case for uninhabited vehicles, robot teammates, and maybe even an outer perimeter of robotic sentries (and, for mobile troops, "a cloud of air and ground robotic systems"). But he also argues that "In general, we should strive to keep humans involved in the lethal force decision-making process as much as is feasible. What exactly that looks like in practice, I honestly don't know."
So does that mean he thinks we'll eventually see the deployment of fully autonomous weapons in combat?
I think it's very hard to imagine a world where you physically take the capacity out of the hands of rogue regimes... The technology is so ubiquitous that a reasonably competent programmer could build a crude autonomous weapon in their garage. The idea of putting some kind of nonproliferation regime in place that actually keeps the underlying technology out of the hands of people -- it just seems really naive and not very realistic. I think in that kind of world, you have to anticipate that there are, at a minimum, going to be uses by terrorists and rogue regimes. I think it's more of an open question whether we cross the threshold into a world where nation-states are using them on a large scale.

An anonymous reader quotes Open Source Observatory:
The City of Barcelona is migrating its computer systems away from the Windows platform, reports the Spanish newspaper El País. The City's strategy is first to replace all user applications with open-source alternatives, until the underlying Windows operating system is the only proprietary software remaining. In a final step, the operating system will be replaced with Linux... According to Francesca Bria, the Commissioner of Technology and Digital Innovation at the City Council, the transition will be completed before the current administration's mandate ends in spring 2019. For starters, the Outlook mail client and Exchange Server will be replaced with Open-Xchange. In a similar fashion, Internet Explorer and Office will be replaced with Firefox and LibreOffice, respectively. The Linux distribution eventually used will probably be Ubuntu, since the City of Barcelona is already running 1,000 Ubuntu-based desktops as part of a pilot...
Barcelona is the first municipality to have joined the European campaign 'Public Money, Public Code'. This campaign is an initiative of the Free Software Foundation Europe (FSFE) and revolves around an open letter advocating that publicly funded software should be free. Currently, this call to public agencies is supported by more than 100 organisations and almost 15,000 individuals. With the new open-source strategy, Barcelona's City Council aims to avoid spending large amounts of money on licence-based software and to reduce its dependence on proprietary suppliers through contracts that in some cases have been closed for decades.Read Replies (0)
