Ask Slashdot: Can Any Wireless Tech Challenge Fiber To the Home? 120

New submitter danielmorrison writes: In Holland, MI (birthplace of Slashdot) we're working toward fiber to the home. A handful of people have asked why not go wireless instead? I know my reasons (speed, privacy, and we have an existing fiber loop) but are any wireless technologies good enough that cities should consider them? If so, what technologies and what cities have had success stories?

Citi Report: Slowing Global Warming Could Save Tens of Trillions of Dollars 160

Layzej writes with news carried by The Guardian about a report published by the Global Perspectives & Solutions division of Citibank (America's third-largest bank) examining the costs and benefits of a low-carbon future. The report examined two hypothetical futures: one "business as usual," and the other (the "Action" scenario) which includes an aggressive move to reduce energy use and carbon emission. From the article: "One of the most interesting findings in the report is that the investment costs for the two scenarios are almost identical. In fact, because of savings due to reduced fuel costs and increased energy efficiency, the Action scenario is actually a bit cheaper than the Inaction scenario. Coupled with the fact the total spend is similar under both action and inaction, yet the potential liabilities of inaction are enormous, it is hard to argue against a path of action." But there will be winners and losers, says the report: "The biggest loser stands to be the coal industry, where we estimate cumulative spend under our Action scenario could be $11.6 trillion less than in our Inaction scenario over the next quarter century, with renewables, wind and nuclear (as well as energy efficiency) the main beneficiaries."

Windows 10 Grabs 5.21% Market Share, Passing Windows Vista and Windows 8 157

An anonymous reader writes: The effects of a free upgrade to Windows 10 are starting to trickle in. Available for just over a month, Windows 10 has now captured more than 5 percent market share, according to the latest figures from Net Applications. In just four weeks, Windows 10 has already been installed on over 75 million PCs. Microsoft is aiming to have 1 billion devices running Windows 10 "in two to three years," though that includes not just PCs, but smartphones, consoles, and other devices as well.

Submission + - Watch Your WiFi Router: It Might be Serving Ads

dkatana writes: It was all over the news last week that AT&T hotspost were using "in-browser content insertion technology" from RaGaPa to insert additional ads on the web pages of their customers. Some people started to complain that their mobile devices started showing unusual ads, some of them taking up half a screen,

Now, thanks to similar technology, your home router could be serving ads too.

Your ISP could be using your home router (the one they provided) to offer WiFi offloading to their mobile customers. Also the router manufacturer could, in theory, send an OTA update to make your router an ad serving machine.

The best thing to do is to purchase your own router and flash it with an open source firmware such as OpenWrt.

Smartphone Malware Planted In Popular Apps Pre-sale 39

An anonymous reader writes with news from The Stack that makes it a little harder to scoff at malware on phones as being largely the fruit of dodgy sideloaded software, game cracks, et cetera. They report that even phones marketed as brand new, from well-known brands like Lenovo and Xiaomi, have been tampered with and "infected prior to sale with intelligent malware disguised in popular apps such as Facebook." (To U.S. buyers, those makers may be slightly obscure as cellphone vendors; the scheme this article addresses involves handsets sold by vendors in Europe and Asia, involving more than 20 different handset types.)

FBI: Burning Man Testing Ground For Free Speech, Drugs ... and New Spy Gear 155

v3rgEz writes: The 29th annual Burning Man festival kicks off this week in Nevada's Black Rock Desert. Among those paying close attention to the festivities will be the FBI's Special Events Management unit, who have kept files on "burners" since at least 2010. One of the more interesting things in those, files, however, is a lengthy, heavily redacted paragraph detailing that the FBI's Special Events Management Unit gave Las Vegas Police Department some specialized equipment for monitoring the week-long event, as long as LVPD provided follow up reports.

Submission + - Should I publish my collection of email spamming IP addresses?

An anonymous reader writes: I have, for a while now, been collecting IP addresses from which email spam has been sent to, or attempted to be relayed through, my email server. I was wondering if I should publish them, so that others can adopt whatever steps are necessary to protect their email servers from that vermin. However, I am facing ethical issues here. What if the addresses are simply spoofed, and therefore branding them as spamming addresses might cause harm to innocent parties? What if, after having been co-opted by spammers, they are now used legitimately? What do Slashdot contributors think?

Submission + - GRSecurity Linux Kernel patch to end public accessability of stable patches.

Gaming Computers Offer Huge, Untapped Energy Savings Potential 180

Required Snark writes: According to Phys.org, a study by Evan Mills at Berkeley Lab shows that "gamers can achieve energy savings of more than 75 percent by changing some settings and swapping out some components, while also improving reliability and performance" because "your average gaming computer is like three refrigerators." Gaming computers represent only 2.5 percent of the global installed personal computer (PC) base but account for 20 percent of the energy use. Mills estimated that gaming computers consumed 75 TWh of electricity globally in 2012, or $10 billion, and projects that will double by 2020 given current sales rates and without efficiency improvements. Potential estimated savings of $18 billion per year globally by 2020, or 120 terawatt hours (TWh) are possible. Mills started the site GreeningtheBeast.org. You can read the full paper as a PDF.

Submission + - How open film project Cosmos Laundromat made Blender better->

An anonymous reader writes: At the beginning of August—the 10th, to be exact—the Blender Institute released Cosmos Laundromat: First Cycle, its seventh open project (and sixth open movie). Cosmos Laundromat (or Project Gooseberry for those who have been following its production from the start) isn't just a 10-minute short film. It's also the Blender Institute's most ambitious project to date, serving as a pilot for the first fully free and open animated feature film.

In his article on Opensource.com animator and open source advocate Jason van Gumster highlights the film project and takes a look at some of its most significant contributions to the Blender open source project.

Submission + - Citi report: slowing global warming would save tens of trillions of dollars->

Layzej writes: Citi Global Perspectives & Solutions (GPS), a division within Citibank (America’s third-largest bank), recently published a report looking at the economic costs and benefits of a low-carbon future. The report considered two scenarios: “Inaction,” which involves continuing on a business-as-usual path, and Action scenario which involves transitioning to a low-carbon energy mix.

One of the most interesting findings in the report is that the investment costs for the two scenarios are almost identical. In fact, because of savings due to reduced fuel costs and increased energy efficiency, the Action scenario is actually a bit cheaper than the Inaction scenario. Coupled with the fact the total spend is similar under both action and inaction, yet the potential liabilities of inaction are enormous, it is hard to argue against a path of action.

Carbon Dating Shows Koran May Predate Muhammad 472

HughPickens.com writes: Brian Booker writes at Digital Journal that carbon dating suggests the Koran, or at least portions of it, may actually be older than the prophet Muhammad himself, a finding that if confirmed could rewrite early Islamic history and shed doubt on the "heavenly" origins of the holy text. Scholars believe that a copy of the Koran held by the Birmingham Library was actually written sometime between 568 AD and 645, while the Prophet Mohammad was believed to have been born in 570 AD and to have died in 632 AD. It should be noted, however, that the dating was only conducted on the parchment, rather than the ink, so it is possible that the Koran was simply written on old paper. Some scholars believe, however, that Muhammad did not receive the Koran from heaven, as he claimed during his lifetime, but instead collected texts and scripts that fit his political agenda. "This gives more ground to what have been peripheral views of the Koran's genesis, like that Muhammad and his early followers used a text that was already in existence and shaped it to fit their own political and theological agenda, rather than Muhammad receiving a revelation from heaven," says Keith Small, from the University of Oxford's Bodleian Library. "'It destabilises, to put it mildly, the idea that we can know anything with certainty about how the Koran emerged," says Historian Tom Holland. "and that in turn has implications for the history of Muhammad and the Companions." Update: 09/01 17:32 GMT by S : There was a typo in the dates used by the original linked article — in the press release from the University of Birmingham, the date range given for the parchment is between 568 AD and 645 AD, which overlaps more closely with Muhammad's lifetime. The dates and link have been fixed now in the summary. Historians say this new information highlights the uncertainty surrounding the emergence of such religious texts, rather than being a major upheaval.
