Ask Slashdot: What Can I Really Do With a Smart Watch?

Slashdot -

kwelch007 writes I commonly work in a clean-room (CR.) As such, I commonly need access to my smart-phone for various reasons while inside the CR...but, I commonly keep it in my front pocket INSIDE my clean-suit. Therefore, to get my phone out of my pocket, I have to leave the room, get my phone out of my pocket, and because I have a one track mind, commonly leave it sitting on a table or something in the CR, so I then have to either have someone bring it to me, or suit back up and go get it myself...a real pain. I have been looking in to getting a 'Smart Watch' (I'm preferential to Android, but I know Apple has similar smart-watches.) I would use a smart-watch as a convenient, easy to transport and access method to access basic communications (email alerts, text, weather maps, etc.) The problem I'm finding while researching these devices is, I'm not finding many apps. Sure, they can look like a nice digital watch, but I can spend $10 for that...not the several hundred or whatever to buy a smart-watch. What are some apps I can get? (don't care about platform, don't care if they're free) I just want to know what's the best out there, and what it can do? I couldn't care less about it being a watch...we have these things called clocks all over the place. I need various sorts of data access. I don't care if it has to pair with my smart-phone using Bluetooth or whatever, and it won't have to be a 100% solution...it would be more of a convenience that is worth the several hundred dollars to me. My phone will never be more than 5 feet away, it's just inconvenient to physically access it. Further, I am also a developer...what is the best platform to develop for these wearable devices on, and why? Maybe I could make my own apps? Is it worth waiting for the next generation of smart-watches?

Australia Moves Toward New Restrictions On Technology Export and Publication

Slashdot -

An anonymous reader writes Australia is starting a public consultation process for new legislation that further restricts the publication and export of technology on national security grounds. The public consultation starts now (a few days before Christmas) and it is due by Jan 30th while a lot of Australians are on holidays. I don't have the legal expertise to dissect the proposed legislation, but I'd like some more public scrutiny on it. I find particularly disturbing the phrase "The Bill includes defences that reverse the onus of proof which limit the right to be presumed innocent until proven guilty" contained in this document, also available on the consultation web site.

India Successfully Test Fires Its Heaviest Rocket

Slashdot -

vasanth (908280) writes India on Thursday moved forward in rocket technology with the successful flight testing of its heaviest next generation rocket and the crew module . The 630-tonne three-stage rocket, Geo-Synchronous Satellite Launch Vehicle Mark III, carried active solid boosters, liquid core stage and a passive cryo stage and a crew module to test its re-entry characteristics. This rocket is capable of doubling the capacity of payloads India can carry into space and it can deposit up to four tonne class of communication satellites into space. India also plans to use this rocket for ferrying Indian astronauts into space. For India, ISRO (the Indian space agency) perfecting the cryogenic engine technology is crucial as India can save precious foreign exchange by launching heavy duty communication satellites by itself.

Cause and Effect: How a Revolutionary New Statistical Test Can Tease Them Apart

Slashdot -

KentuckyFC writes Statisticians have long thought it impossible to tell cause and effect apart using observational data. The problem is to take two sets of measurements that are correlated, say X and Y, and to find out if X caused Y or Y caused X. That's straightforward with a controlled experiment in which one variable can be held constant to see how this influences the other. Take for example, a correlation between wind speed and the rotation speed of a wind turbine. Observational data gives no clue about cause and effect but an experiment that holds the wind speed constant while measuring the speed of the turbine, and vice versa, would soon give an answer. But in the last couple of years, statisticians have developed a technique that can tease apart cause and effect from the observational data alone. It is based on the idea that any set of measurements always contain noise. However, the noise in the cause variable can influence the effect but not the other way round. So the noise in the effect dataset is always more complex than the noise in the cause dataset. The new statistical test, known as the additive noise model, is designed to find this asymmetry. Now statisticians have tested the model on 88 sets of cause-and-effect data, ranging from altitude and temperature measurements at German weather stations to the correlation between rent and apartment size in student accommodation.The results suggest that the additive noise model can tease apart cause and effect correctly in up to 80 per cent of the cases (provided there are no confounding factors or selection effects). That's a useful new trick in a statistician's armoury, particularly in areas of science where controlled experiments are expensive, unethical or practically impossible.

Will Ripple Eclipse Bitcoin?

Slashdot -

First time accepted submitter groggy.android writes This year's biggest news about Bitcoin may well turn out not to be the repeat of its surge in value last year against the dollar and other state currencies but its impending eclipse by another independent but corporate-backed digital currency. Popularly known as Ripple, XRP shot up in value last year along with other cryptocurrencies that took advantage of the hype around Bitcoin. However, among the top cryptocurrencies listed in Coinmarketcap.com, a site that monitors trading across different cryptocurrency exchanges, Ripple is the only one that not only regained its value after the collapse in the price of Bitcoin but has more than doubled from its peak last year. In September it displaced Litecoin to become the second most valuable cryptocurrency. Even more surpising, a Ripple fork, Stellar, is one of the two other cryptocurrencies in the Coinmarketcap top ten that have risen sharply in value during the last few weeks. What makes Ripple different from Bitcoin? Strictly speaking, Ripple isn't the name of the digital currency but of the decentralized payment network and protocol created and maintained by the eponymous Ripple Labs. Users of the Ripple system are able to transact in both cryptocurrency and regular fiat currency like the dollar without passing through a central exchange. XRP is the name of the native unit of exchange used in the Ripple network to facilitate conversion between different currency types.

After 40 Years As a Double Amputee, Man Gains Two Bionic Arms

Slashdot -

MojoKid writes Les Baugh, a Colorado man who lost both arms in an electrical accident 40 years ago, is looking forward to being able to insert change into a soda machine and retrieving the beverage himself. But thanks to the wonders of science and technology — and Johns Hopkins University Applied Physics Laboratory (APL) — he'll regain some of those functions while making history as the first bilateral shoulder-level amputee to wear and simultaneously control two Modular Prosthetic Limbs (MPLs). "It's a relatively new surgical procedure that reassigns nerves that once controlled the arm and the hand," explained Johns Hopkins Trauma Surgeon Albert Chi, M.D. "By reassigning existing nerves, we can make it possible for people who have had upper-arm amputations to control their prosthetic devices by merely thinking about the action they want to perform."

Did Alcatraz Escapees Survive? Computer Program Says They Might Have

Slashdot -

In June of 1962, three prisoners escaped the penitentary on Alcatraz, in an elaborate plot that was dramatized in a Clint Eastwood movie. A question that has long puzzled the public is whether these men ever made it to shore; the many factors that made Alcatraz a secure prison include sharks, cold water, and contrary currents. Still, some artifacts from the attempt, and perhaps the appeal of stories about survival against high odds, have led many people to believe that the men actually landed safely and faded into society. coondoggie writes This week Dutch scientists from Delft University of Technology presented findings from a computer modeling program they were working on, unrelated to the mystery, that demonstrated the escapees could have survived the journey. "In hindsight, the best time to launch a boat from Alcatraz was [11:30 am], one and a half hours later than has generally been assumed. A rubber boat leaving Alcatraz at [11:30 am] would most likely have landed just north of the Golden Gate Bridge. The model also shows that debris in that scenario would be likely to wash up at Angel Island, exactly where one of the paddles and some personal belongings were found.

Hackers Compromise ICANN, Access Zone File Data System

Slashdot -

Trailrunner7 writes with this news from ThreatPost: Unknown hackers were able to compromise vital systems belonging to ICANN, the organization that manages the global top-level domain system, and had access to the system that manages the files with data on resolving specific domain names. The attack apparently took place in November and ICANN officials discovered it earlier this month. The intrusion started with a spear phishing campaign that targeted ICANN staffers and the email credentials of several staff members were compromised. The attackers then were able to gain access to the Centralized Zone Data System, the system that allows people to manage zone files. The zone files contain quite bit of valuable information, including domain names, the name server names associated with those domains and the IP addresses for the name servers. CANN officials said they are notifying any users whose zone data might have been compromised." (Here's ICANN's public note on the compromise.)

Reaction To the Sony Hack Is 'Beyond the Realm of Stupid'

rossgneumann writes North Korea may really be behind the Sony hack, but we're still acting like idiots. Peter W. Singer, one of the nations foremost experts on cybersecurity, says Sony's reaction has been abysmal. "Here, we need to distinguish between threat and capability—the ability to steal gossipy emails from a not-so-great protected computer network is not the same thing as being able to carry out physical, 9/11-style attacks in 18,000 locations simultaneously. I can't believe I'm saying this. I can't believe I have to say this."

To Fight Currency Mismatches, Steam Adding Region Locking to PC Games

Slashdot -

will_die writes Because of recent currency devaluation Steam has now added region locking for games sold in Russia and CIS. Brazil and local area and Indonesia and local area are also being locked. If you purchase a game from one of those regions you cannot gift it to somone outside of the area. So someone from Russia can gift a game to someone to Georgia [Note: This Georgia, rather than this one, that is.] but not to someone in the USA. You want to see the prices in the Russia store and compare them to the Steam Christmas Sale which should be starting in a few hours.

Who's To Blame For Rules That Block Tesla Sales In Most US States?

Slashdot -

cartechboy writes The common assumption among Tesla fans seems to be that state auto-dealer lobbyists are working with Republican legislators to enact laws banning direct sales of Tesla's electric cars to retail buyers. Is it true? The New York Times published an article with some data points that assesses the supposition. While the article mainly focuses on the conflict between Uber and the Republican party, some quotes could be easily applied to Tesla. For instance, Republican National Committee chairman Reince Preibus said, "It should be consumers, not government bureaucrats or legislators, that deicde what companies get our business." The author of the article, Josh Barro, wrote that 22 states permit direct sales of automobiles by Tesla to retail buyers, and of those the majority--14 of them-- voted for President Obama. He suggested that Democratic California, Illinois, and New York "have freer markets in auto retailing than Texas," which is presently Republican. When looking at a five-year-old article by Nate Silver that looked at political donations by car dealers, fully 88 percent of those donations went to Republican candidates, and just 12 percent to Democrats. That possibly suggests a propensity among Republican state legislators to support the interests for car dealers over those of electric-car buyers. Is the small bit of evidence enough to make a case? Good background on the current system of dealership sinecure can be found in this short 2009 Competition Advocacy Paper from the U.S. Department of Justice, which delves into the history and effects of the dealers-only system which still prevails.

Councilmen Introduce Bills Strongly Regulating UAV Use in NYC

Slashdot -

SternisheFan passes on this excerpt from an Ars Technica article: On Wednesday Councilman Dan Garodnick introduced a bill to the New York City council seeking to ban all use of drones except those operated by police officers who obtain warrants. A second, parallel bill introduced by councilman Paul Vallone would place more stringent restrictions on drone use but stop short of banning drones for hobbyists and companies altogether. Both bills have been passed to the city's committee on public safety. An all-out ban on drones within the metropolis would be a quite wide-reaching step, especially as the Federal Aviation Authority (FAA) seems poised to adopt more permissive rules, with respect to commercial interests in particular. Earlier this year, the FAA formally granted six Hollywood companies exemptions to drone ban rules. A couple of months later, the FAA granted similar exemptions for construction site monitoring and oil rig flare stack inspections. The article explains that Vallone's bill is less restrictive, and rather than propose an outright ban "lists 10 instances where operating a UAV would be illegal, including at night, out of the operator's eyesight, or above 400 ft high. Outside of those conditions, hobbyists and commercial interests would be free to fly drones."

US Links North Korea To Sony Hacking

Slashdot -

schwit1 writes Speaking off the record, senior intelligence officials have told the New York Times, CNN, and other news agencies that North Korea was "centrally involved" in the hack of Sony Pictures Entertainment. It is not known how the US government has determined that North Korea is the culprit, though it is known that the NSA has in the past penetrated North Korean computer systems. Previous analysis of the malware that brought down Sony Pictures' network showed that there were marked similarities to the tools used in last year's cyber-attack on South Korean media companies and the 2012 "Shamoon" attack on Saudi Aramco. While there was speculation that the "DarkSeoul" attack in South Korea was somehow connected to the North Korean regime, a firm link was never published.

Christmas light sequencer

Raspberry Pi -

Over at Instructables, Osprey22 (what’s your real name, 22? Let us know and I’ll add it to this post) is driving audio and eight strands of lights (plus a jolly twinkly star) from the same Raspberry Pi, so the two can be sequenced using some custom Python he’s written. Play to the end for a bit of Let it Go, if you’ve not heard it too many times this year already.

Osprey22 has made full build instructions available, along with all the code you’ll need, and sequencer files for a few Christmas choons. We love it.

Startup Helps You Build Your Very Own Picosatellite On a Budget
