comment Lists - pairing up
@ssch good question, I can't find it either, I just assumed it will work since this is a common level specification used by many other similar commands. So, I would have to say yes, but I am no expert in Mathematica specs, may be someone would know. At least it does give same results for this example. i.e {2} or {{2}}.

comment Is there an open source implementation of Mathematica-the-language?
hi, just to make sure I understand, are you saying that the Wolfram Language is/will be an "open-source" implementation of language Mathematica?

comment How to negate a boolean vector?
doing ??Not shows Not is not Listable. If a function foo is Listable, then one can write foo[{....}], and then foo will automatically by applied to each element in the list. For example, if you do ??Sin you'll see it says it is Listable. For non-listable functions, you can use Map, as in Map[Not,{True,False,True}] or Not[#] & /@ v etc... So, the first thing to always check is to do ?? in order to see if a function is Listable or not.

comment CDF embedding in HTML
It is really VERY simple to put CDF in HTML. No need for javascript, just use the line you showed, <embed src="AGN-standaloneClear.cdf" width="1380" height="6792"> All what you have to do is manually adjust the width value and the height value to your liking. That is what I do. I set it at width="700" height="700" and see if this showed the whole Manipulate or not. If not, I adjust the numbers. It only takes one or 2 tries to get the right numbers you want. This is how I have been adding CDF's to my pages for a very long time, never had a problem. Save CDF as standalone and all document.

comment Incorrect result from Integrate
@MichaelE2 good points about branch cuts. But I have thought the math/computer expert folks have decided on these things long time ago (PrincipalValue?) else one CAS will give one result, depending on its choice, and another will give different result for same problem because it decided to go another path (as it seems in this case). Any way, will have to learn more about these things myself one day. Good observations, thank you.
