Re:A New Wireless Hack Can Unlock 100M Volkswagens on Saturday August 13, 2016 @01:15PM (#12282190)
These security issues are not exclusive to computer systems in cars. A valet recently used my physical car key to unlock a different car. (Same make, different model.) He only realized he was in the wrong car when the ignition wouldn't turn.

All DOS are because of humans?
Why would they? What if he comes back to post another video?
Kids these days.
fb probably shut it down. It had footage of a shooting. Very sad and grim stuff.

Re:Reasons not to use (i.e., be used by) Facebook on Sunday June 26, 2016 @02:50PM (#11982063)
Everything else aside, the first Guardian article linked to under "Miscellaneous" [1] suggests that it will take more than a well reasoned argument to get people to leave facebook.

Wouldn't a 4 digit PIN be really fast to hack? And then all of your passwords are belong to us?

From a browser, you can also use bangs to search a specific site from duckduckgo. Stackoverflow is !so.

Is there any similar service in the US?

Can it make coffee?
It's a neat idea, and yea, support for adding a photo would be nice.

Is there a way to do self hosting? There's no indication whatsoever about what happens to the data that users might enter, and many would see this as a privacy concern.

Is the source code available somewhere?

Let's hope it stays dead.
Getting a patent with no real intent of building a product should not be possible.
It should be easy for them to get the satellites up: just point them up and multiply by the right scalar.

A bit of a bummer that http://evil.martinfowler.com/ resulted in Server Not Found.

Re:Why 5 x 3 = 5 and 5 and 5 Was Marked Wrong on Saturday October 31, 2015 @01:28PM (#10483355)
If the author of this article instead references the definition of multiplication of natural numbers on wikipedia [1], then the student is correct since $a \times b = a + a + \dots + a$ with that definition.

Without access to this particular teacher's curriculum materials, it's not possible to know for sure what definition is being referenced by the "repeated addition strategy". I'm inclined to assume the teacher knows what they're doing and has graded the work appropriately.

There are many comments on this thread about multiplication being commutative by definition, but this is not quite correct. Following the same definition of multiplication I cited above, it is a theorem that $a \times b = b \times a$. When I teach Abstract Thinking (a sort of introduction to proof writing course for mathematics students), I have the students write proofs for this property of multiplication of natural numbers, and the other familiar properties (cancellation, distribution, etc.). If anyone is interested, I've broken the steps out into worksheets that I give to my students, and you can see them at the link below. [2] [pdf] (Multiplication of natural numbers is section 5.5.)

I don't know. What If I took that page and divided it into <div>'s, removed the middle one, and replaced the others with copies of the original page? Then, I could take each of those <div>'s, break them into pieces, remove the middle one, and replace the others with copies of the original page. Then...
Why does the keyword search drop the final character if it is an 's'? For example, when I search for 'dress' the message I receive is 'Showing 0 images tagged dres'
