Comment Re:My B.S. Detector is Going Off (Score 1) 76

...lack of familiarity with the terms used in RF engineering.

Got beaten to the punch here. I was about to submit this confusing quote from TFA:

the two-wire ribbons used during televisionâ(TM)s first few decades to send RF signals from rooftop VHF antennas to television sets without any loss. The electric RF current in the two conductors flow in opposite directions and have opposite phase. Because of the translational symmetry (the two conductors are parallel) the radiation fields cancel each other out, so there is no net radiation into space.

Took a few reads before I finally figured out they were referring to 300-ohm twin lead...

Comment Re:Lets say yes so they put an FM radio on my phon (Score 1) 350

he summary reads like an NAB astroturf campaign.

This. This is the terrestrial broadcasters trying to stay relevant in a world where they increasingly are not due to streaming. Just like the electric companies fighting solar tooth and claw, broadcasters are having to deal with Netflix, Hulu, and so on.

"Screaming, 'We're too important during emergencies to not have around!' worked for ham radio," the broadcasters must be thinking, and the FCC, at least, seems to agree. For FM, at least, they don't have to worry about encumberance from cell phones, unlike UHF TV.

Personally, though, I think almost all terrestrial broadcast is a waste of bandwidth, but I know that's not the popular opinion even here on /.

Gigafactory (and friends)

That is, disconnect from the grid entirely. Once rechargables come down decently in price per cycle ((dis)charge) and price/watt-hour, there won't be a need to put up with this. This can only apply to residential and some small business, of course, as factories take in may times what power they could generate themselves, but the utilities should be scared, especially as they work to piss off people even more than telecom/cable utilities.

Comment Re:So much for long distance Listening (Score 1) 293

I've been thinking about this for years: the same problem affects DMR (MotoTRBO and friends) and D-STAR (and its sibling NXDN) and seems related to diversity, sub-standard trellis and other ECC, and so on that were solved in cell (mobile) phone standards a decade or two ago: most(all?) of the solutions are patented, which is a problem for D-STAR but not for the others. It's just clear the companies involved don't want to put any effort into fixing these problems.

Comment Question: How many people actually care? (Score 1) 293

I hardly listen to the wasteland that is broadcast radio other than to check traffic or propagation conditions. I know we're talking about Norway, but is the broadcast radio there worth listening to? It sure isn't here in the USofA. :(

tl;dr if this happened in USA tomorrow I probably wouldn't notice for a week or more; how about you?

Oh, please, pot meet kettle:

Google has only been acting really evil in the last few years; for M$, Oracle, and many other companies, doing evil is corporate policy and they have *NEVER* STOPPED being evil. To put it another way, Oracle is the Monsanto of software, M$ is the DuPont of software, and Google is more like factory farms, doing both good and evil at the same time. (I freely admit the Google comparison is weak--please feel free to come up with a better one.)

I have no problem with Google being investigated, but they should go after M$ as well, especially with what they did to Nokia, Linux, and Android; fat chance that'll happen, though.

Comment Missing tag for this story: CYANOGEN (Score 4, Interesting) 245

I couldn't figure out why Google wasn't getting pissy AT ALL over Cyanogen forking and talking smack about them.. Now the other shoe has dropped: Cyanogen's fork (and the company's very existance) is Google's main anti-trust defense, at least at the OS level.

Now Google's ad business, that's a whole 'nother matter...

Comment Re:uhh...wrong Wikipedia article (Score 1) 173

https://en.wikipedia.org/wiki/Horse_latitudesare what you are referring to. These deserts are referred to as "sub-tropical", as opposed to, say, the northern Great Basin or eastern Washington, which is mainly created from rain shadowing.

Also, Sahara is north of the equator (the desert, the street, and the casino).

Comment Re:Legitimate Uses (Score 1) 74

IMO we shouldn't outlaw a technology purely because of what someone could do with it. It's the act of invading someone's privacy that should be outlawed. This accomplishes the same thing while preserving the multitude of legitimate uses for these devices.

Tell that to the NSA, FBI, CIA, etc. (If not in USA, substitute for your own equivalent like GCHQ, GRU, etc.)

Submission + - How the government just protected some of your favorite podcasts (washingtonpost.com)

schwit1 writes: When you're listening to your favorite podcast — This American Life, maybe, or Radiolab — patents are probably the last thing on your mind. But behind the scenes, the podcasting world has been living in fear of one particular patent that threatens to force many independent producers out of business.

Now, a government board has revoked key parts of that patent, handing a huge victory to podcasters.

Submission + - As encryption spreads, U.S. grapple with clash between privacy, security (washingtonpost.com)

schwit1 writes: For months, federal law enforcement agencies and industry have been deadlocked on a highly contentious issue: Should tech companies be obliged to guarantee U.S. government access to encrypted data on smartphones and other digital devices, and is that even possible without compromising the security of law-abiding customers?

NSA director Adm. Michael S. Rogers wants to require technology companies to create a digital key that could open any smartphone or other locked device to obtain text messages or photos, but divide the key into pieces so that no one person or agency alone could decide to use it?

What's to stop the FISA court from secretly ordering all key masters to secretly give their key to the NSA? How would we know that the government doesn't already have all of the keys?

Hallie Siegel writes: Should robots be allowed to make life and death decisions? This will be the topic of heated debate at the United Nations (UN) Palais des Nations in Geneva next week (April 13-17th, 2015). As part of the Convention on Certain Conventional Weapons (CCW), experts from all over the world will gather to discuss “questions related to emerging technologies in the area of lethal autonomous weapons systems.” The Open Roboethics Research Initiative will be presenting public views at the debate.

Submission + - Google Lollipop Bricking Nexus 5 and Nexus 7 devices 2

Zape writes: The Lollipop update has turned sour for me and several other Nexus 7, Gen 2 (and Nexus 5) owners. It seems that I'm not alone in having my tablet boot to the Google Logo since a couple of days after updating to Android 5.0.2. Now Nexus 5 owners are reporting a reboot loop in Android 5.1. My device, like many others, is a couple of months out of warranty, but worked great until the latest OTA update from Google. They branded it, and they updated it, but Google claims it is between the buyers and ASUS, the manufacturer.
