Costa Rica Goes 75 Days Powering Itself Using Only Renewable Energy

An anonymous reader writes with news about an impressive renewable energy accomplishment in Costa Rica. Costa Rica has achieved a clean energy milestone by using 100 per cent renewable energy for a record 75 days in a row. The feat was achieved thanks to heavy rainfall, which powered four hydroelectric plants in the first three months of the year, the state-run Costa Rican Electricity Institute said. No fossil fuels have been burnt to generate electricity since December 2014, in the state which is renowned for its clean energy policies.” Read more of this story at Slashdot.

For Boot Camp Users, New Macs Require Windows 8 Or Newer

For anyone using Windows 7 by way of Apple’s Boot Camp utility, beware: support for Windows via Boot Camp remains, but for the newest Apple laptops, it’s only for Windows 8 for now. From Slashgear: This applies to the 2015 MacBook Air, and the 13-inch model of the 2015 MacBook Pro. Windows 8 will remain compatible, as will the forthcoming Windows 10. The 2013 Mac Pro also dropped Boot Camp support for Windows 7, while 2014 iMacs are still compatible, along with 2014 MacBook Airs and 2014 MacBook Pros. For those who still prefer to run Windows 7 on their Macs, there are other options. This change to Boot Camp will not affect using the Microsoft operating system through virtualization software, such as Parallels and VMware Fusion. Also at PC Mag.

Feds Fine Verizon $3.4 Million Over 911 Service Outage Issues

itwbennett writes The U.S. Federal Communications Commission has fined Verizon $3.4 million over its failure to notify police and fire departments during a 911 service outage last year. Under the commission’s rules, Verizon and other carriers were required to notify emergency call centers of a six-hour outage that occurred in April. The outage involved multiple carriers and affected over 11 million people in seven states. Read more of this story at Slashdot.

Full-Duplex Radio Integrated Circuit Could Double Radio Frequency Data Capacity

Zothecula writes Full-duplex radio communication usually involves transmitters and receivers operating at different frequencies. Simultaneous transmission and reception on the same frequency is the Holy Grail for researchers, but has proved difficult to achieve. Those that have been built have proven complex and bulky, but to be commercially useful in the ever-shrinking world of communications technology, miniaturization is key. To this end, engineers at Columbia University (CU) claim to have created a world-first, full-duplex radio transceiver, all on one miniature integrated circuit. Read more of this story at Slashdot.

Project an Interactive Game on Your Floor or Wall (Video)

Lumo is an interactive projector. You can use it to bore people with PowerPoint slides or you can use it as a game machine. It has a built-in (low res) camera that can detect a kick (as shown at the beginning of the video) and make a (virtual) ball move as a result of that action. ‘But, ‘ you ask, ‘do they have an Indiegogo campaign?’ Not yet. It launches on March 23. The Lumo projector was originally designed for commercial use at children’s museums and as a trade show attention-getter — at $10, 000 a pop. The consumer version is expected to cost less than $500, according to Lumo CEO (and Slashdot interviewee) Meghan Athavale. And while she doesn’t talk much about it in the interview, if you already have a computer, a projector, and a Kinect or webcam, you can buy the a stripped-down version of the company’s ‘interactive-floor-wall projection’ software for $39, plus games or customizable game templates.

Researchers Find Same RSA Encryption Key Used 28,000 Times

itwbennett writes In the course of trying to find out how many servers and devices are still vulnerable to the Web security flaw known as FREAK, researchers at Royal Holloway of the University of London found something else of interest: Many hosts (either servers or other Internet-connected devices) share the same 512-bit public key. In one egregious example, 28, 394 routers running a SSL VPN module all use the same 512-bit public RSA key. Read more of this story at Slashdot.

$56,000 Speeding Ticket Issued Under Finland’s System of Fines Based On Income

HughPickens.com writes Joe Pinsker writes at The Atlantic that Finish businessman Reima Kuisla was recently caught going 65 miles per hour in a 50 zone in his home country and ended up paying a fine of $56, 000. The fine was so extreme because in Finland, some traffic fines, as well as fines for shoplifting and violating securities-exchange laws, are assessed based on earnings—and Kuisla’s declared income was €6.5 million per year. Several years ago another executive was fined the equivalent of $103, 000 for going 45 in a 30 zone on his motorcycle. Finland’s system for calculating fines is relatively simple: It starts with an estimate of the amount of spending money a Finn has for one day, and then divides that by two—the resulting number is considered a reasonable amount of spending money to deprive the offender of. Then, based on the severity of the crime, the system has rules for how many days the offender must go without that money. Going about 15 mph over the speed limit gets you a multiplier of 12 days, and going 25 mph over carries a 22-day multiplier. Sweden, Denmark, Germany, Austria, France, and Switzerland also have some sliding-scale fines, or “day-fines, ” in place, but in America, flat-rate fines are the norm. Since the late 80s, when day-fines were first seriously tested in the U.S., they have remained unusual and even exotic. Should such a system be used in the United States? After all, wealthier people have been shown to drive more recklessly than those who make less money. For example Steve Jobs was known to park in handicapped spots and drive around without license plates. But more importantly, day-fines could introduce some fairness to a legal system that many have convincingly shown to be biased against the poor. Last week, the Department of Justice released a comprehensive report on how fines have been doled out in Ferguson, Missouri. “Ferguson’s law enforcement practices are shaped by the City’s focus on revenue rather than by public safety needs, ” it concluded. The first day-fine ever in the U.S. was given in 1988, and about 70 percent of Staten Island’s fines in the following year were day-fines. A similar program was started in Milwaukee, and a few other cities implemented the day-fine idea and according to Judith Greene, who founded Justice Strategies, a nonprofit research organization, all of these initiatives were effective in making the justice system fairer for poor people. “When considering a proportion of their income, people are at least constantly risk-averse. This means that the worst that would happen is that the deterrent effect of fines would be the same across wealth or income levels, ” says Casey Mulligan. “We should start small—say, only speeding tickets—and see what happens.” Read more of this story at Slashdot.

Scientists Insert a Synthetic Memory Into the Brain of a Sleeping Mouse

the_newsbeagle writes: Scientists are learning how to insert fake memories into the brain via precise electrical stimulation (abstract). In the latest experiment, they gave sleeping mice a synthetic memory that linked a particular location in a test chamber to a pleasurable sensation. (At least they gave the mice a nice memory.) The researchers first recorded the electrical signals from the mice’s brains while the mice were awake and exploring the test chamber, until the researchers identified patterns of activity associated with a certain location. Then, when the mice slept, the researchers watched for those neural patterns to be replayed, indicating that the mice were consolidating the memory of that location. At that moment, they zapped a reward center of the mice’s brains. When the mice awoke and went back into the chamber, they hung around that reward-associated location, presumably expecting a dose of feel-good. Read more of this story at Slashdot.
