Submission + - Best resources for ARM and small form factor computing? 1

thesandbender writes: I'd like to get into development with small form factor computing as a hobby but it seems every week there's new announcements for commercial and crowd-sourced projects and it's difficult to get a good handle on all the offerings out there and how they stack up against each other. What are the recommendations for blogs or aggregators that track this sort of thing?

Submission + - New Study Helps Uncover The Nature Of Cosmic Rays

fergus07 writes: Using data from the IceCube Neutrino Observatory at the South Pole, scientists from the University of Delaware have reported progress in understanding the longstanding mystery of how and where cosmic rays originate. The research could help us find ways to shield astronauts and electronics from cosmic radiation, but it also shows that things are even more complicated than we thought.

Comment Re:Moving parts is undesirable for mobility (Score 2) 201

Moving parts means that the device is inherently more fragile... less resilient to shock, and introduces points of physical failure that don't exist with solid state storage.

Disk drives act like gyroscopes, however smaller drives can stop faster and have less rotational momentum at the same RPM.
Flash is shock sensitive too. I've ruined USB flash sticks by dropping them. I hate moving parts too, but I think it's possible to make a mechanical drive less shock sensitive then flash with the proper safety features. Your experience with standard drives isn't really relevant to these new mobile drives because they are very different physically.

I say give them a chance and we will see how they perform.

Submission + - Researcher Spots A Drug Buy In Bitcoin's Blockchain (forbes.com)

Sparrowvsrevolution writes: "It should come as no surprise to Bitcoin users that despite the pseudonymity the cryptocurrency offers, its transactions can be tracked. But University of California at San Diego researcher Sarah Meiklejohn proved that privacy problem more clearly than ever by showing a reporter that she could detect a specific point in Bitcoin's blockchain record of transactions where he had spent Bitcoins in exchange for marijuana on the Silk Road, the most popular online Bitcoin-based black market for drugs.

To simulate a law enforcement subpoena, the reporter for Forbes began by giving Meiklejohn a Bitcoin address associated with Forbes' account. But with just that information, Meiklejohn was able to draw on a "clustering" analysis she had performed to identify Silk Road addresses and match them with the one used in the .3 BTC drug buy. She admits that a user who took more efforts to obscure his or her Bitcoin address through a laundering service or other unidentified Bitcoin wallets would be harder to track."

Submission + - Global warming? No, actually we're cooling, claim scientists (telegraph.co.uk) 1

bricko writes: Global warming? No, actually we're cooling, claim scientists
A cold Arctic summer has led to a record increase in the ice cap, leading experts to predict a period of global cooling.

  There has been a 60 per cent increase in the amount of ocean covered with ice compared to this time last year, they equivalent of almost a million square miles.

In a rebound from 2012's record low an unbroken ice sheet more than half the size of Europe already stretches from the Canadian islands to Russia's northern shores, days before the annual re-freeze is even set to begin.

The Northwest Passage from the Atlantic to the Pacific has remained blocked by pack-ice all year, forcing some ships to change their routes.

A leaked report to the UN Intergovernmental Panel on Climate Change (IPCC) seen by the Mail on Sunday, has led some scientists to claim that the world is heading for a period of cooling that will not end until the middle of this century.

Especially since it will likely be supplementary to a standard smart phone. I still need my large screen to browse the internet. I want a smart watch with an unfolding screen. Unfortunately a watch is difficult to use with thumbs, si it also needs to be detachable.

Unfortunately the CEC specification was poorly written in HDMI 1.4. Besides some standard buttons most of the CEC commands were mostly defined by the manufacturer.

Personally, I've had trouble with CEC with a Yamaha receiver coupled with a Samsung TV. Whenever the TV turned on it switched the receiver into Audio Return Channel mode, which was incorrect because it was on the HDMI/cable input. ARC should have been disabled until going into the smart tv mode. I ended up using a TOSLink cable, turning of CEC and switching the inputs manually on the receiver. Interoperability needs to be improved between manufacturers.

The 1.4 specification doesn't define the CEC commands well enough. With advanced features like ARC, it's even more important to define proper behavior.
Supposedly this is better in HDMI 2.0, but we will see how the actual implementation compares.
