Why P-values Cannot Tell You If a Hypothesis Is Correct

c++0xFF Oblig XKCD (124 comments)

http://xkcd.com/882/

Even the example of p=0.01 from the article is subject to the same problem. That's why the LHC worked for something like 6 sigma before declaring the higgs boson to be discovered. Even then, there's always the chance, however remote, that statistics fooled them.

German Court Forbids Resale of Valve Games

c++0xFF Re:Bad ruling (261 comments)

I'm just waiting for other industries to start realizing the brilliance of licensing something instead of selling it. Imagine "buying" a house, when in reality all you did was obtain a license to use a copy of a house design. You might own the land the house is on. You can sell the land, but the license for the house is non-transferable. Except maybe under specific conditions stipulated in the license (which probably involves a transfer of money to the home builder or whomever owns the "copyright" on the home design).

I would think that nobody would agree to such a thing, so it could just be buried somewhere in the mountain of paperwork you have to sign anyway. Nobody reads that legalese anyway, right? (If you can't tell, the last time I went through this process the letters E U L A kept going through my mind.)

OK, so maybe a house is too extreme of an example, but the same principle could be applied to almost any item.

The software industry somehow made this standard without most of the population of the world knowing. You say that "it is well understood that they sell licenses, not complete copyrights" but I completely disagree. Most people don't even know what a license is to begin with. And it's a concept that (so far) is limited to the digital world. Books, photographs, sculptures ... yeah, you can't legally make copies of any of them, and everybody knows that. But since when did I not actually purchase that book? Since when could the author/publisher prevent me from selling that book to my friend?

The reason for this confusion, I think, is that you don't buy a license to begin with. License is a verb, not a noun, in this case. You don't buy a game. You are licensed to use a copy of it. A license is a contract, not a physical object. You are not allowed to make further copies, except as stipulated by the licensing agreement. A license is something you're granted. It's not something you purchase, as that would imply ownership. If you "owned" a license (a contradiction in terms, really), then you should be able to resell that license to someone else. That's what ownership means.

What digital media realized is that without a physical object to own (not even a CD anymore, as if that stopped them to begin with), there was nothing to buy. Nothing to hold, nothing to resell. The copyright retains control over all copies, not just control over the ability to make copies -- and that's what this is all about.

AMD Announces First ARM Processor

c++0xFF Re:Despite it's name (168 comments)

The war is over, and x86 won. But it didn't win because it's the best, but because of economics, marketing, and the quirks of history.

It's the same story everywhere in technology, be it instruction sets, MP3 players, or video media. The winner only needs to be good enough. And x86 has been good enough, hasn't it? Not the best, of course, and by accident some things (like SSE, as you pointed out) have even been made easier.

And yet, the computing world would be better off if we could somehow break our backwards-dependency on x86 to something faster and more efficient.

CES 2014: There's a 'Pre-Show' Before the Consumer Electronics Show (Video)

c++0xFF Re:Beautiful 4K upscaling (43 comments)

But ... isn't 4k just a simple upscale of 720 and 1080? Use four pixels for each pixel of 1080 and nine for each pixel of 720? Maybe I'm just ignorant, though.

Federal Judge Rules Chicago's Ban On Licensed Gun Dealers Unconstitutional

c++0xFF Re:Took them long enough... (934 comments)

That's exactly what they were doing. The Constitution specifically says that the definition of a militia would be provided by congress at a future date:

The Congress shall have Power ... To provide for organizing, arming, and disciplining, the Militia, and for governing such Part of them as may be employed in the Service of the United States, reserving to the States respectively, the Appointment of the Officers, and the Authority of training the Militia according to the discipline prescribed by Congress;

LLVM and Clang 3.4 Are Out

c++0xFF Re:pretty quick on the C++14 support (118 comments)

They're not "fully integrated." IDEs can only call the gcc command, and have no access to internal data structures. The GPL prevents these IDEs from using the libraries directly.

Compare this to clang which provides a library API and has the license (BSD-like) to back this up.

Apple Forges Agreement With China Mobile

c++0xFF Re:Peak Apple 2012 (79 comments)

Becuase revenue and profits should somehow matter on Slashdot. We're mostly techies here, not investors. Market share is a much better metric for things we're interested in.

When I see a company charging significantly more for a marginally better product, I think "price gouging" and "profiteering" not "exceptional company." but maybe that's just me.

Besides, even investors are worried that the ever-decreasing market share is eventually going to catch up to the high-margin pricing model eventually. Maybe that's in the next couple years (a common view, it seems), but I think it'll be a while yet.

Patent Battle May Loom Over 'Copenhagen Wheel' Electric Bike

c++0xFF Re:Why Bother? (152 comments)

2. Even more people live in places where the gradients or distances are enough to break out in a sweat when cycling. Which is fine if it's a simple work-out. But not good if you are using the bike for transport to somewhere where there isn't a shower at the other end. Battery assist can help you arrive smelling sweeter.

Sweat isn't smelly. It sounds a little odd, but an alternative is to take a shower before cycling. That gets you nice and clean so the bacteria don't get you smelly. Then, at your destination, just freshen up (towel down, deodorant, change clothes, and fix your helmet hair).

That said ... being sweaty isn't exactly pleasurable, so your overall point still applies.

How 3 Young Coders Built a Better Portal To HealthCare.gov

c++0xFF Re:How would it handle a large load? (499 comments)

Yeah, someone needs to verify that information. The HealthSherpa passes that responsibility on to the insurance company, which isn't a terrible way to do it anyway.

How 3 Young Coders Built a Better Portal To HealthCare.gov

c++0xFF Re:How would it handle a large load? (499 comments)

Playing around with the HealthSherpa, it provides a quick and easy way to specify household size and income, and then updates the prices with the subsidy. Very, very easy. It's also very easy to list the ages and smoking status of people covered by the insurance, and again updates prices accordingly.

The biggest feature it's missing is a plan comparison. All it shows is the premium and coinsurance (in the form of plan type). Sometimes you can guess the copay or deductible from the plan name. Is that information public?

Re: Daylight Saving Time, I would most like

c++0xFF Re:This (462 comments)

Yes, some people actually exercise outside. Cycling is a great form of exercise, and is much better when done during daylight hours.

Keeping DST, for me at least, means I can commute by bike more without messing with headlights, etc.

Movie Review: Ender's Game

c++0xFF Re:Orson Scott Card (732 comments)

You're thinking of the Homecoming Saga, which is basically a reworking of the plot and stories in The Book of Mormon in science fiction format.

Ender's Game only has a few oblique references to anything Mormon (Ender's mother was raised Mormon, for example).

Blockbuster To Close Remaining US Locations

c++0xFF Re:does everyone REALLY have IP-connected TV? (419 comments)

Chromecast. If memory serves me right, a decent VCR cost twice that much back in the day, note even counting for inflation.

Caveat: still need a TV with HDMI ... but even those can be had for cheap anymore.

Hello, Streisand Effect! The only way to not give publicity to someone is to ignore him. Not seeing a movie is one thing... but the vitriol against Card from "homophobephobes" is quite another.

Movie Review: Ender's Game

Ender's Game was originally a short story. Maybe they should have based the movie on that instead of the book?

Microsoft, Apple and Others Launch Huge Patent Strike at Android

c++0xFF Re:Justia link (476 comments)

That's not how patents work.

The only thing that matters with patents, in the end, are the claims. That's it, end of story. So, let's look at the claims. Actually, there's only one claim, which makes this easy.

We claim:
1. A method of searching for desired information within a data network, comprising the steps of:
receiving, from a user, a search request including a search argument corresponding to the desired information;
searching, based upon the received search argument and user profile data, a database of information to generate a search result; and
providing the search results to the user
wherein searching the database includes correlating, as a function of a fuzzy logic algorithm, the received search argument and user profile data to particular information in the database, and providing the particular information as the search results.

Simplifying a bit...

We claim a method for searching for information.
Step 1) Get request from user
Step 2) Search a database using a fuzzy algorithm and user profile
Step 3) Give information to the user

Notice there's not a word about advertisements anywhere in that. The patent talks about ads in the various descriptions, but there's not even a dependent claim relating to ads. Displaying ads is just a use case, not the invention itself.

Step 1 and 3 are quite obvious. So the real "invention" here is applying fuzzy algorithms to search.

For prior art, I hereby present the BackRub search engine, March 1996 (about a year before the patent filing date). That's right ... Google is the prior art for this patent. And I'm sure there's others.

Most Sensitive Detector Yet Fails To Find Any Signs of Dark Matter

Plausible. But before we go down that path, I say we try the more conventional means of explaining dark matter ... Occam's Razor, and all that.

MELT, a GCC Compiler Plugin Framework, Reaches 1.0

c++0xFF Re:Too little too late (58 comments)

Let me translate. "Great" in this case means "non-GPL" (YMMV, of course). If you want to link into the compiler code itself (rather than just calling the compiler binaries), you've just forced your IDE to use the GPL.

LLVM, on the other hand, has a more permissive license, so it's a non-issue. And it was built with this sort of IDE-compiler interaction in mind, so there's that, too.

Google add bicycle directions to maps

c++0xFF c++0xFF writes  |  more than 4 years ago

c++0xFF (1758032) writes "In response to online petitions, Google has launched bicycle directions on its popular mapping web site. The enhancements include an overlay with trails and bike paths, and the directions take into account hills and traffic.

Will this encourage more people to commute on bicycle or to enjoy the outdoors?"
