comment Asking back technical questions during the interview (as the interviewee)
Not sure I agree with "use lots of terms that lesser developers wouldn't understand" - I often find that it's the lesser-developers who throw around the fancy marketing words (like constantly using the phrase 'n-tier', or naming off every design pattern under the sun), whereas the better developers understand what they are, but only use them in conversation when it's absolutely appropriate, which is pretty rare. This could really make you look bad.

comment Is it wise to be going back and forth between two programming languages?
@Tacroy: But the question is specifically about programming languages. OP most likely already knows HTML/CSS/Javascript/SQL if he does web-development in PHP; but he's not asking about that. He's asking if learning another programming language would be a good idea.

@luis.espinal: Did you read the top answer? (which is definitely "a source" for any claim of "most programmers think"...)

@luis.espinal: It's pretty common knowledge. Here's a source.

comment Is it wise to be going back and forth between two programming languages?
Most people only consider something a "Programming language" if it can be used for programming things (ie. is Turing Complete). HTML, XML, Regex, CSS, XPath/XSLT/XQuery are not considered programming languages; neither is the tiny subset of SQL used by most developers.

comment How big does my project need to be for me to unit test it?
Uh, I think you missed one: "Making sure the code works the way it's supposed to!"

comment Why the question “give five things you hate about C#” is so difficult to answer during an interview?
What use-case could you have for variable number of generic types that type-constraints wouldn't solve? Also, read-only properties are supported (public MyProperty { get; private set;), but they are usually considered a code-smell

comment Why aren't design patterns added to the languages constructs?
There is also a school of thought (to which I belong) that says design patterns are just workarounds for deficiencies in a language. In their eyes, all existing design patterns would not exist in the perfect language; but considering the most popular languages are far from perfect, we're stuck with these workarounds. (Example)

comment What would be the Impact of P=NP?
@David: Wikipedia is (somewhat) incorrect; semantic security is a property that is desired in all encryption-schemes. The confusion probably comes from the fact that, currently, the only known provably secure encryption schemes are asymmetric (due to their inherently mathematical nature). Note that RSA is not one of them.

comment What would be the Impact of P=NP?
@Jerry: David is confused. Both encrypting and decrypting with a block cipher, given the key, are already in P; however, if you are not given the key, the problem is no longer in NP, since you cannot verify in polynomial time that the output of a semantically-secure cipher is actually an encrypted string (this is one of the definitions of a semantically-secure cipher). Also, for the record (in response to Macneil/Mason) - one time pads alone are not secure against man-in-the-middle attacks, even if both sides already have the key.

comment What would be the Impact of P=NP?
+1 for the third bullet point - everyone knows that P=NP would affect crypto, but for some reason you rarely hear about how it would affect literally every other computing discipline on the planet.

I would prefer file.save(useEncryption: false)

comment Is it wrong to use a boolean parameter to determine behavior?
@Ray: I don't see a difference between those two questions. In a language where you can enforce the use of named parameters, or when you can be sure named-parameters will always be used (eg. private methods), boolean parameters are fine. If named parameters can't be enforced by the language (C#) and the class is part of a public API, or if the language doesn't support named parameters (C++), so that code like myFunction(true) might be written, it's a code-smell.
