Submission + - Cloud's real ecological timebomb: Wireless, not data centres (computerworld.com.au)

Submitted by angry tapir
angry tapir writes: New research from an Australian university argues that increased carbon emissions from powering data centres aren't the biggest environmental threat from the growth of cloud computing. Instead, the problem is the Wi-Fi and cellular networks increasingly used to access cloud services. By 2015, the energy used to run data centres will be a "drop in the ocean" compared to the energy used to power wireless access to services. By 2015 the energy consumption associated with 'wireless cloud' will reach 43 terawatt-hours, compared to 9.2 terawatt-hours in 2012 (an increase in carbon footprint from 6 megatonnes of CO2 in 2012, up to 30 megatonnes of CO2 in 2015). Data centres will comprise only 9 per cent on this increased energy consumption, compared to up to 90 per cent for wireless access.

Submission + - Lawmakers Propose Revisions to CISPA to Ease Privacy Concerns (securityweek.com)

Submitted by wiredmikey
wiredmikey writes: Backers of the controversial Cyber Intelligence and Sharing Protection Act (CISPA), said they would propose amendments to the bill, under which Internet companies can give the government information about what they see as potential security threats and they are protected from liability for providing the information.

The measure has provoked a storm of protests, with civil libertarians claiming such laws could allow too much government snooping and conservatives say they would create new bureaucracy.

The lawmakers claim to be listening to those concerns, but explained that the issue has become more pressing recently with revelations about new cyber threats.
Greg Nojeim of the Center for Democracy and Technology said the changes failed to address one key concern — that information could be accessed by the NSA. The lawmakers said they would insert a more narrow definition of national security in the bill.

Lawmakers are expected to meet Wednesday to vote on the issue, which passed the House last year but died in the Senate.

What Does It Actually Cost To Publish a Scientific Paper? 166

Posted by Unknown Lamer from the one-trillion-dollars dept.
ananyo writes "Nature has published an investigation into the real costs of publishing research after delving into the secretive, murky world of science publishing. Few publishers (open access or otherwise-including Nature Publishing Group) would reveal their profit margins, but they've pieced together a picture of how much it really costs to publish a paper by talking to analysts and insiders. Quoting from the piece: '"The costs of research publishing can be much lower than people think," agrees Peter Binfield, co-founder of one of the newest open-access journals, PeerJ, and formerly a publisher at PLoS. But publishers of subscription journals insist that such views are misguided — born of a failure to appreciate the value they add to the papers they publish, and to the research community as a whole. They say that their commercial operations are in fact quite efficient, so that if a switch to open-access publishing led scientists to drive down fees by choosing cheaper journals, it would undermine important values such as editorial quality.' There's also a comment piece by three open access advocates setting out what they think needs to happen next to push forward the movement as well as a piece arguing that 'Objections to the Creative Commons attribution license are straw men raised by parties who want open access to be as closed as possible.'"

Comment Samsung image tarnished with Android (Score 4, Interesting) 107

Say what you will about Apple & the iPhone, but I appreciate the tight integration of OS & hardware and their desire to provide a consistent & reliable user experience. I own and use a (Sprint) Samsung Galaxy S2 Epic 4G Touch, and it was a series of broken promises on ever getting ICS. When finally rolled out, it wasn't the true android experience, but some half-baked Samsung-proprietary interface aka "Touchwiz." Great, that wasn't what I was sold when I purchased the device. I want android, not Samsung's half-baked, bug-filled, garbage-software-filled version of it.

Eventually, I rooted and installed JB, because Samsung sure as heck wasn't going to do that. And then, as you venture deeper into the rooting environment, you find out a bunch of hardware/software issues directly caused by Samsung, including but not limited the EMMC super-brick bug. These security issues in TFA are just more of the same. For me, their handling of their android phones and my experience with them has tarnished their image across their entire product fleet. Will I buy a Samsung brand washer/dryer? There's a lot of digital tech in even washing/drying machines nowadays. Before this, their name wasn't an issue. Now, maybe I consider some other brand.

well instead of developing the green tech to compete we must artificially increase the cost of the dirty fuel! we cant use plain old light bulbs anymore, that use more power (and give off heat, thus meaning one could in theory keep their heater lower) and now we are stuck with CFLs that are worse for the environment than the old bulbs!

You should have stopped before this sentence.

Insofar as "cheap" "dirty" vs "expensive" "clean" environmentalism is concerned, the problem is that it is difficult to capture (i.e., within a product's price) the cost of all the externalities ( https://en.wikipedia.org/wiki/Externality ). Therefore, we have "cheap" "dirty" fuels, which are actually more expensive than the clean fuels, but the costs of all of their negative externalities have not been included, and therefore only perceived as cheap by the average individual. For example, super-fine particulate matter (i.e., 2.5 microns in diameter), most commonly generated as a fuel combustion byproduct, is a serious contributor to adverse health effects and mortality rates; these health & life effects do translate into costs, though they aren't currently well-reflected in the prices of the products and/or energy choices you can select.

Therefore, we raise the cost of these "dirty" energy sources through artificial means in an attempt to better account for the non-artificial (but hard to encapsulate) externalities.

= LibreOffice doesn't read or write the constantly mutating, rubbish file formats of MS Office the way only MS Office can.

While I recognize it's perhaps not a fair judge of LibreOffice, life isn't fair. I use LibreOffice and like it, and can handle the quirks when using non-native documents. But when even faced with "it's free vs. it costs you money", even ridiculously frugal people like my father WILL NOT SWITCH. His primary concern is his clients are able to read & use the documents he provides--and that conversely, he's able to read & use the documents his clients provide--without any hassle whatsoever. Let's face it, perfect interoperability with zero hassle is a big seller these days; look at Apple.

Only some people will comprise on price vs functionality. But nearly EVERYONE will switch to Libreoffice when they can save big on price without any compromise on functionality.

The market is saturated now.

No, this is wrong. There was a very good story on NPR just 1-2 days ago about Apple the bind it's in re: emerging middle class in China. The numbers were staggering, on the order of 200 MILLION people expected to get a smartphone in the next 1-2 years (and because Apple sells a premium, very-expensive product out of the price range of 99% of those 200 million, is likely to miss out huge unless they radically diverge from their current sales & marketing plan... but I digress).

If Blackberry can rebound and sell an inexpensive, desirable smartphone in China, they could totally recover.

So there's a copyrighted look, a trademarked name, and a patented design. Players demand real brand-name stuff in their games, so developers deliver by licensing real brand-name stuff in their games. To do this legally means getting a license.

What's so shady about that?

So, read the actual article.

The article's arguments, for the "TLDR" crowd, amount to this:
1. Like the candy cigarettes before them, the depiction of realistic guns--especially with the real names attached--amounts to advertisement towards a target population of young individuals, to influence them to purchase the real thing. They provide some anecdotal evidence that it works. As a personal anecdote, I know that it's worked on me (I own a BB gun that's a model of the USP .50; it was my favorite gun & skin from Counter-strike 1).

2. The "shady" part is that the game companies would, seemingly universally, prefer not to talk publicly about any of this (i.e., that there's any ongoing collaboration, licensing, or even two-way discussion between them and gun manufacturers). This is likely a socially-perceived "negative" topic, and therefore discussing it would likely negatively impact sales by casting their companies in a negative light.

Like candy cigarettes, any advertising of an inherently dangerous/deadly product towards an adolescent target audience probably should be carefully scrutinized, regulated, or eliminated.
