10 Years of the MacBook Air (theverge.com) 152

Ten years ago today, Steve Jobs introduced the MacBook Air. "Apple's Macworld 2008 was a special one, taking place just days after the annual Consumer Electronics Show had ended and Bill Gates bid farewell to Microsoft," The Verge recalls. "Jobs introduced the MacBook Air by removing it from a tiny paper office envelope, and the crowd was audibly shocked at just how small and thin it was..." From the report: At the time, rivals had thin and light laptops on the market, but they were all around an inch thick, weighed 3 pounds, and had 8- or 11-inch displays. Most didn't even have full-size keyboards, but Apple managed to create a MacBook Air with a wedge shape so that the thickest part was still thinner than the thinnest part of the Sony TZ Series -- one of the thinnest laptops back in 2008. It was a remarkable feat of engineering, and it signaled a new era for laptops. Apple ditched the CD drive and a range of ports on the thin MacBook Air, and the company introduced a multi-touch trackpad and SSD storage. There was a single USB 2.0 port, alongside a micro-DVI port and a headphone jack. It was minimal, but the price was not. Apple's base MacBook Air cost $1,799 at the time, an expensive laptop even by today's standards.

Renewable Energy Set To Be Cheaper Than Fossil Fuels By 2020, Says Report (independent.co.uk) 261

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.

City-Owned Internet Services Offer Cheaper and More Transparent Pricing, Says Harvard Study (arstechnica.com) 113

An anonymous reader quotes a report from Ars Technica: Municipal broadband networks generally offer cheaper entry-level prices than private Internet providers, and the city-run networks also make it easier for customers to find out the real price of service, a new study from Harvard University researchers found. Researchers collected advertised prices for entry-level broadband plans -- those meeting the federal standard of at least 25Mbps download and 3Mbps upload speeds -- offered by 40 community-owned ISPs and compared them to advertised prices from private competitors. The report by researchers at the Berkman Klein Center for Internet & Society at Harvard doesn't provide a complete picture of municipal vs. private pricing. But that's largely because data about private ISPs' prices is often more difficult to get than information about municipal network pricing, the report says. In cases where the researchers were able to compare municipal prices to private ISP prices, the city-run networks almost always offered lower prices. This may help explain why the broadband industry has repeatedly fought against the expansion of municipal broadband networks.

'Don't Fear the Robopocalypse': the Case for Autonomous Weapons (thebulletin.org) 150

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.

And if so, I think it's worth asking, what do we mean by"them"? What degree of autonomy? There are automated defensive systems that I would characterize as human-supervised autonomous weapons -- where a human is on the loop and supervising its operation -- in use by at least 30 countries today. They've been in use for decades and really seem to have not brought about the robopocalypse or anything. I'm not sure that those [systems] are particularly problematic. In fact, one could see them as being even more beneficial and valuable in an age when things like robot swarming and cooperative autonomy become more possible.
