comment What part of the kernel is open sourced?
I think you are confusing "open source" with "open" as in "open to inspection".

comment Interactive ListPlot by mouse clicking
This is an elegant answer. I think it would even more elegant with toolRule = Tooltip[x__] :> PopupWindow[Tooltip[x], popupGraph @ #2&[x]];

comment How to center a graphic in its output cell
@Edmund. You should post your comment as an answer. Short as it is, it is a complete and useful answer.

comment How would one set up a conditional to evaluate at the last output value (wondrous numbers)
You will find a lot about your project by searching this site on "collatz" -- the sequences you are generating are often referred to as Collatz sequences.

comment Interactive ListPlot by mouse clicking
You should look atClickPane. If you give your list plot as the first argument, the action function in the second argument with get the point that was clicked on in plot coordinates. You can write the action function to find the nearest pair in your list of data pairs and use the found pair to select the what you want to display.

comment Looping through 3 million elements of a list to 'Set' values is slow
I don't think this produces what the OP is asking for. I think he is asking for a zero-order interpolation.

comment Are these codes the same?
You post this code as if it were yours, but you make it clear that you don't understand it. I conclude you have appropriated someone else's code, modified it in some way based on guess-work, and expect it to work. That is a recipe for disaster.

comment How can I avoid getting the message Solve::ratnz?
Please do not bring up more and more issues in comments. This site is not a discussion forum. I have given your problem a lot of time;I do not more time to give to it.

comment Solve won't solve $x = y^2 - z^2$ for $z$
It is very likely that somewhere in your notebook you assigned values to some combination of x, y, z. Try starting a new Mathematica session with a clean notebook. Enter you solve expression. It should now work.

comment How to delete subsets quickly?
@ciao. I just posted the modified code that I used for the time trials. My solution seems to perform at about O(n^1.5).

I told my doctor, "When I do this it hurts". He told me, "Then don't do that". :P

comment Different solutions for seemingly same Integral
I'm voting to close this question as off-topic because the problem the user is experiencing can not be reproduced by others.

@ciao. I have a new version of my code that can run your benchmark. The average timing (4 trials) is 70 sec on my 4-yr old iMac.

comment How to find a Sylow p-group?
The issue this question raises is not a Mathematica issue but a mathematical one. That it is formulated in terms of Mathematica is not sufficient to make it an appropriate question for Mathematica.SE.

comment How to delete subsets quickly?
@ciao. My code works with 5000 sets in the data list, but crashes the kernel with 10000. This is beginning to look like a problem I previously experienced with Total. See (this question)[mathematica.stackexchange.com/q/37132/3066]

comment How to delete subsets quickly?
@ciao. Can't run your benchmark. When I try I get a kernel crash after several minutes of runtime. Determined it is not a memory problem. Don't have time to look at it further at this time (past 3 AM in my time zone). Will look it again tomorrow. Provisional assessment is that one or both of ContainsAll or AnyTrue has very bad performance, not to mention having trouble working on large lists.

comment Combining lists to create points to plot with ListLinePlot
@GumpyCede. Follow-up questions should be put to the whole community, either by editing the original question or (better) by asking a new question. But I'll give you a hint -- follow this link and click on the links there that mention models or regression.
