The future of logging in online will look like this.

What's different about this? The secret never leaves the device. The device proves (via cryptography) that it knows the secret.

That's very different than passwords, where you have to repeat the secret "out loud" every time you log in. That just keeps giving attackers more chances to overhear it.
Security experts have told us for years that we should have long, complex passwords that are different for every website…

If there's a PIN on a hardware signing device then it IS two factor. Something you have (the device) and something you know (the PIN).

Also, I think bitauth has nothing whatsoever to do with any block chain, other than that it uses the same crypto libs.

Come on, +Sam Harris, you're giving atheists a bad name.

You know perfectly well, that after we die, there's no review of your life to score how well you did.

You're trying to portray life as, "we're these beautiful important beings, and we'll all going to be destroyed soon. Everything we do between now and then is very important!"

That is not true and you know it. Would anyone notice a single grain of sand missing from a beach? Our planet isn't even a grain of sand to the universe. The laws of physics do not permit us to affect the universe in any appreciable way, no matter how clever or creative or kind we are. Whatever the purpose of the universe, we have no role whatsoever in its outcome.

Atheists aren't depressing because we believe these important beings are destroyed. We're depressing because we believe we were never important in the first place. Except it actually isn't depressing when you think about it.

If nothing we do matters, then we can stop feeling anxious. We can also stop feeling anxious by telling ourselves we'll live forever.  The only difference is, our insignificance is true, and living forever is just a fantasy.

Why should I bother pointing all this out, if none of it matters? Well, gotta do something.

As a hedonist and sworn enemy of the pain and suffering, I do agree on almost everything you said. But, just as you compare our importance with large things(planets, stars so forth) you should also compare us with small things. You do matter to the bacteria that dwells within you, trillions of them can thrive just because you choose to live on. Your biome makes up you just as we make up earth's biosphere.

Vsauce posted a wonderful video the other day about how we are really at the center of the universe, on a logarithmic scale.

Hashing an unordered list:

I thought that I would easily find an algorithm to do this. What I want is to take an unordered list, and apply a hash function to it such that it will give the same result regardless of the order of the list.

Obviously, the simplest solution (from a software engineering perspective) is to use a standard function like SHA256, but sort the list before applying the hash function.

I thought there would be a more elegant solution, for example, SHA256 all the items and then sum the hashes. However this may be insecure, since obviously there are more ways to arrive at a sum than just permutations of your original list - eg, [1, 2, 3, 4] sums to 10 but you can also get that from [5, 5], [1, 1, 8], etc. I'm not mathematically advanced enough to figure out whether this breaks collision resistance, but certainly seems plausible that it would.

I don't know of any commutative function I could use to reduce the individual hashes, other than addition and multiplication. There's XOR but I read there's definitely an attack on that, just not sure if the same attack applies to addition and multiplication.

So my question is, why isn't there function that does this in common crypto libs? And if I did want to do it, is there a secure and practical way, other than sorting the items first?

BTW depending on the problem you're trying to solve (e.g. "did I see this element previously") you might look at specialised algorithms that happen to use "hashes of hashes" concept, such as Bloom filter.

Mozilla is Crushed by Microsoft/NSA  Abandoning Google for Microsoft (via proxy Yahoo) will cut off 90%of Mozilla's budget in a move that makes little sense.  The Microsoft press stupidly claims that "Google no longer needs Mozilla because they have Chrome" but that's divide and conquer.  Microsoft also has a browser and has little need for Mozilla other than to ruin a competitor.  Besides advertisements, Mozilla will be sending user keystrokes to Microsoft/NSA.  Microsoft and the NSA are not interested in Windows user's keystrokes, they already have that, they are interested in OSX, Android and GNU/Linux users.  

Perhaps this is why Mozilla's CEO was publicly humiliated and run off by the Microsoft press.

I think Snowden made me a little less dismissive of such theories, especially when MS is involved.

If they are putting up the money for Firefox, its as good as corrupt, as far as I'm concerned.

+David Dickens Though, games are a little different. Unlike office software and the like that are important for running a productive environment. Games are meant to be experiences such as movies, music, and books.

"No one should be asking what we’re going to do if computers take our jobs.

"We should all be asking what we get to do once freed from them."

The beginning of the end of labor as we know it is starting. This will fundamentally disrupt our existing socioeconomic system. Whether this leads to dystopia or utopia rests largely in the hands of politicians.

Yeah. I'm sure they'll make the right decisions.

TIL - People are STILL watching "Gangnam Style" more than any other YouTube video?  "It's been over two years, but instead of finding something new on the internet, let's watch Gangnam Style again!"

Huh. It list the wikipedia page as source, which doesn't really list “views per day”.

Though checking that, it lists the Nov.26's views as 2,145,343,240, and today the youtube says it is 2,163,021,823, which makes for ~1.6M views/day.

Which is still a lot, indeed.

But anyway, the source / method of the graph is unclear.

This is the future of payments.  Apple Pay is just lipstick on a pig.

As usual, the Simpsons said it best:

Moe: "All right, I just found out that 96% of the traffic accidents in this town are caused by you four guys."

Most of the drinking in the US is done by a small minority of drunks.  This should not surprise anyone who's ever been to a party.  And the US isn't even close to the hardest-drinking country.  Imagine what you'd have to drink to be in the top 10% in Russia.
The top 10 percent of American drinkers consume more than 10 drinks per day.

Via +Dat Moose This is NOT a soldier. This is how the police looks in #Ferguson 

"There's a reason you separate military and the police. One fights the enemies of the state, the other serves and protects the people. When the military becomes both, then the enemies of the state tend to become the people." - William Adama, Battlestar Galactica
Today in Ferguson, following the arrest of two journalists police continued their all out assault on the liberties and rights of the town's citizens. Here's the latest update on what we know so far.

This is one of my local favorites, I usually eat here at least once a week. The food is good quality for the price, and the portions are large. Some dishes are better than others, and some are better deals than others. My favorite is the Pork Carnitas. The dinner specials are a good deal - portions big enough for two people for about $10. The prices have gone up since they moved to their current location, back when they were at South Square, my wife and I would split a dinner special and get a couple of (alcoholic) drinks for about $15 including tip. It's not quite that cheap anymore, around $20-22 now, but still very reasonable.

For take-out, especially sushi, this is one of the better places around. The quality is very good for the price - be sure to order similarly priced rolls if you want the best 2-for-1 deal. Eating in at the restaurant isn't quite as appealing to me, as others have mentioned the service isn't very friendly. However I will say that the service is prompt and competent.
