Slashdot's projected-growth department:
An anonymous reader quotes a report from Computerworld written by Lucas Mearian: By 2040, coal, natural gas and renewable energy sources will provide roughly equal shares (28%-29%) of world electricity generation -- a tremendous change from 2012, when coal provided 40% of all power generation, according to a new report. The report, International Energy Outlook 2016, was released today by the U.S. Energy Information Administration (EIA). Renewables are now the world's fastest-growing energy source and are expected to increase by 2.6% per year through 2040. Hydropower and wind are the two largest contributors to the increase in world electricity generation from renewable energy sources, the report stated. Together, hydro and wind account for two-thirds of the total increase in renewable energy from 2012 to 2040. In contrast, coal is the world's slowest-growing energy source, rising by 0.6% per year through 2040. By 2030, natural gas surpasses coal to become the world's second-largest energy source after liquid fuels, the report stated. The world's energy consumption is expected to increase by 48% over the next three decades even as renewable energy sources increase. Fossil fuels will still supply more than three-quarters of the world's energy by 2030. Currently, China, the U.S. and India are the top three coal-consuming countries, making up 70% of the world's coal use. China's coal use is expected to decline as their economy slows and policies to combat air pollution and climate change become implemented. The Environmental Protection Agency's new Clean Power Plan regulations intend to dramatically lower the use of coal in the U.S. over the next three decades. "Of the world's three largest coal consumers, only India is projected to increase coal use throughout the projection period," the report stated.

Slashdot's boost-in-storage department:
Samsung recently unveiled its EVO Plus 256GB microSD card, capable of storing more than 12 hours of 4K video footage, 33 hours of full HD recording, 55,200 photos or 23,500 MP3s. While you most likely do not need such a large microSD card in your life, you'll probably want one. The card features Samsung's newest V-NAND technology, with read/write speeds of 95MB/s and 90MB/s, respectively. It will be available in June to over 50 countries at a price of $250, which includes a 10 year warranty. Personally, I have no need for such a high-capacity card at this time, but I marvel how far technology has progressed in the last few years, let alone months. SanDisk, for example, revealed a 200GB microSD card back in March, 2015, which was the highest capacity microSD card up until now.

Slashdot's Shiva-Ayyadurai-wants-fame department:
Mike Masnick, reporting for TechDirt: Oh boy. Remember Shiva Ayyadurai? The guy who has gone to great lengths to claim that he "invented email," when the reality is that he appears to have (likely independently) written an early implementation of email long after others had actually "invented email." In the past we've called out examples where gullible press have fallen for his easily debunked claims, but he keeps popping back up. The mainstream press repeated his bogus claims about inventing email after he married a TV star. And, most recently, he decided to scream at the press for memorializing Ray Tomlinson -- someone who actually did have a hand in creating email -- upon his death. [...] We, of course, have not been alone in debunking his claims. Back in 2012, a few weeks after we first debunked them, Gawker's Sam Biddle did a long and thorough takedown of Ayyadurai's claims. Apparently that story really angers Ayyadurai, and I'm guessing that seeing Hulk Hogan win his crazy lawsuit against Gawker helped Ayyadurai to decide to sue Gawker as well.

Slashdot's we-have-to-go-deeper department:
An anonymous reader shares a report on The Verge: Scientists have found 74 genetic variants that are associated with educational attainment. In short, that means some people have variants of genes in their DNA that are correlated with completing more schooling. But this finding, published today in Nature, should be taken with a grain of salt. Together, these variants explain less than half a percent of the differences in educational attainment seen in the population studied -- far less than the impact that a person's wealth and environment can have on the time they spend in school. The strongest association found for a single genetic variant explained only 0.035 of one percent of the variation in educational attainment. "Put another way, the difference between people with zero and two copies of this genetic variant predicts, on average, about nine extra weeks of schooling," says Dan Benjamin, a behavioral economist at the University of Southern California who worked on the study. These variants don't mean much when it comes to people's schooling, and factors like poverty, geography, and nutrition probably have a much bigger combined impact. The Guardian's take is worth a read as well.

Slashdot's how-to-train-a-programmer department:
An anonymous reader has shared an interesting article that talks about one of the most common challenges faced by novice developers: "I know how to program, but I don't know what to program." The author of the article also shares his views on some of the most common solutions for that problem: "do programming challenges", "contribute to an open source project", or "make a game." From the post: Doing programming challenges is good mental practice, but they do little to help someone learn how to create a new program. Contributing to an open source project is a step up. You might learn about how a real project is structured and improve your skill with the programming language, but you won't learn much about the full lifecycle of a project. Some projects are very complex too which can be intimidating for a novice. Making a game is another step up. Games are fun! I started by programming games in QBASIC. The same dilemma arises though. "I want to make a game, but I don't know what to make." The author advises these beginners to try rewriting a library which already exists (despite this being considered as a prohibited practice by many). Developers should also not wait to get the "best idea" before they begin writing it, the author adds. From the post: I've seen the same mentality with musicians. Trying to create a masterpiece on their first attempt, putting all their energy into one song and not seeing a bigger picture. The bigger picture being, you will write LOTS of songs over time, not just one!

Slashdot's curious-case-of-self-driving-cars department:
Here's the thing, regardless of one's stand on self-driving cars, they are no longer a futuristic idea. Major car companies such as Tesla, BMW, and Mercedes have already released an autonomous vehicle or plan to release one soon. Sergio Marchionne, an Italian-Canadian executive who is currently the CEO of Fiat Chrysler Automobiles, recently said: It isn't pie in the sky. People are talking about 20 years. I think we will have it in five years. ZDNet has published its interview of Jim McBride, technical leader in Ford's autonomous vehicles team, who thinks self-driving cars are five years away from changing the world. At the same time, we must acknowledge the talks about these smart vehicles killing many jobs, and the security vulnerabilities we read every once in a while. What's your take on this?

Slashdot's the-grand-tour-fans department:
Jasper Jackson and Dugald Baird, writing for The Guardian: Amazon's new motoring show starring Jeremy Clarkson, Richard Hammond, and James May will be called The Grand Tour. In a statement, the former Top Gear trio thanked fans for taking the time to send in their suggestions for the name, which they said were "much appreciated". "Thing is," said Clarkson, "we'll be travelling the world hosting each episode in a different country, from a giant tent. It's a sort of 'grand tour', if you like. So we've decided to call it The Grand Tour." May said he was underwhelmed by the name. "I wanted to call it 'Nigel', or 'Roger'," he said. "We needed a name, and they're names." Hammond was more positive. "I already love camping," he said. "But this is something else. We are like our pioneering and prospecting forebears, sallying forth into a new frontier of broadcasting, and making our home where."

Slashdot's DIY department:
HughPickens.com writes: More than one million Americans live with Type 1 diabetes, an autoimmune condition in which the pancreas stops producing insulin, a hormone needed to turn sugar into energy. Now Kate Linebaugh writes at the WSJ that Jason Calabrese, a software engineer, followed instructions that had been shared online to hack an old insulin pump so it could automatically dose the hormone in response to his son's blood-sugar levels. The Calabreses aren't alone. More than 50 people have soldered, tinkered and written software to make such devices for themselves or their children. Initially, Calabrese worried about the safety of the do-it-yourself project. He built it over two months, and spent weeks testing. At first, he only tried it out on his son on weekends and at night. Once it performed well enough, he said it felt irresponsible not to use it on his 9-year-old son. "Diabetes is dangerous anyway. Insulin is dangerous. I think what we are doing is actually improving that and lowering the risk," says Calabrese. The home-built project that the Calabreses followed is known as OpenAPS. The only restriction of the project is users have to put the system together on their own. As long as the people tinkering with their insulin pumps aren't selling or distributing them, the FDA doesn't have a legal means to stop it. The system involves an outdated insulin pump that communicates with a small radio stick connected to a continuous glucose monitor, a computer motherboard and a battery pack. It is an outgrowth of another open-source project where caregivers developed software to remotely monitor blood-sugar levels. The size of the homemade system varies, and the one that Calabrese carries has come down from the size of a small shoebox to that of a headphone case. He wears his insulin pump and glucose monitor on his belt. "It is clearly for people who have some expertise in computer programming," says Bruce Buckingham. "What it shows is that people are anxious to get something going."

An anonymous reader writes: Hacker, BVM, said he's "lost count" of the number of subreddits he's stolen and defaced, but estimates that the number is more than 70. Subreddits like r/pics, r/starwars, and r/gameofthrones, and many others, have been defaced just in the last few days. He claims Reddit's crummy security, and lack of two-factor authentication are what has made his exploits possible. "Reddit's security is shit," he says. "If Reddit would simply add 2FA it would be a lot harder to get in." Why is BVM hacking these subreddits? "No reason really. Just boredom. It's not like it's really a challenge or anything so I just do it to pass time," the hacker told Motherboard in an online chat. BVM didn't comment on how exactly he is taking over subreddits. However, he did admit he's been hacking into moderators' accounts and then changing the CSS style of the pages, replacing it with a note taking responsibility. Reddit appears to be responding to these incidents quickly, restoring the subreddits.
