How to find roots of $X^5 - 1$? How to find roots of $X^5 - 1$? (Or any polynomial of that form where $X$ has an odd power.) What young adult SF book is about a boy saved by aliens and domed colonies? From what I understood, cardinal numbers are defined as:  $\aleph_0$ = the cardinality of $\mathbb{N}$ $\aleph_{n+1}$ = is the least cardinal number greater than $\aleph_n$  The continuum hypothesis states that the cardinality of $\mathbb{R}$ is  $\aleph_1$. I more or less understand this cannot be proven (does not follow from ZFC).  However, can it be proven dat there in fact is a 'least cardinal number' greater than $\aleph_0$?  Is it possible that there are sets with cardinality $\aleph_{1/2}$, $\aleph_{1/3}$, et cetera, so to speak?  Or expressed differently: is it possible that for every set A with cardinality CA > $\aleph_0$, there exists another set B with cardinality CB where CA > CB > $\aleph_0$? Exercise $1.8$ of chapter one in Hartshorne. In exercise 1.8 of chap I in Hartshorne algebraic geometry,       Let $Y$ be an affine variety of dimension $r$ in $\mathbf A^n$. Let $H$ be a hypersurface in $\mathbf A^n$, and assume that $Y \nsubseteq H$. Then every irreducible component of $Y \cap H$ has dimension $r-1$.     I refered to a . In this solution, why $f$ is not a unit in $B$? Adding script conditionally Where can I find header files in C on unix I reviewed  in the First Posts queue.  Which said      i changed it to 'localsystem' and done. thanks much   So it obviously was a potential low quality post. But sometimes such answers can be spot on, so I checked it out, better safe than sorry. I turned out the post had been deleted. Great! So I clicked "No action needed". Then I got this:    You can imagine I felt "wrongfully accused".  I think that deleted posts should not be used for review audits, because the meaning of "No action needed" is not clear in this context. Showing $F[x,y]/(ax^2+by^2-1)$ is a Dedekind domain A term for when people insist on giving you help you didn't ask for? People love to tell other people what to do. It may not be control, so much as trying to help, especially when you've asked for help directly. However, there's a difference between answering someone's question and answering while piling on recommendations the person didn't ask about, and this is what I'm seeking a term for. Advertising and marketing feel similar to me in this vein. In the worst cases this can be overzealous religious followers professing your damnation if you don't follow with them (I think in Christianity they call it "witnessing"). Any which way, it comes across to me as a form of unsolicited advice: I didn't ask for it, so I don't want it; I want to stay focused.  Is there a better term for this than "unsolicited advice"? Also, is there a term for a person who exhibits this kind of behavior frequently? Invisible software updates list in Software Updater How do I check whether a module is installed in Python, and install it if needed? In terminal, after I start Python, how will I know what are the modules present in python? Suppose I need to learn the modules NumPy and SciPy.   How will I install it if it is not installed?  How will I know if it is already installed? How can I retrieve data within my widget I have a Widget which I am creating but my quesiton is how do I access my custom table which I created via my plugin.

I know we use the yield mechanism in order to allow the next frame to be processed, while the download is being completed. But what is going on under the hood when we do the yield return www ?   What method is being called (if any, on the WWW class)? Is Unity using threads? Is the "upper" Unity layer getting hold of www instance and doing something?  EDIT:   This question is specifically about Unity3D internals. I'm not interested in explanations of how yield statement works in C#. Instead, I'm looking for an inside view of how Unity deals with these constructions, to allow, for example, to WWW to download a piece of data in a distributed manner across several frames.

Don't show pending suggested edits to me after I run out of votes Now that I've reached 2k on Stack Overflow, I get access to the "Suggested Edits" review queue.

Proving an inequality involving the logarithm function: $\frac{1}{n+1} \leq \ln \left(1+\frac 1n\right) \leq \frac 1n$ The question is to prove the inequality $$\frac{1}{n+1} \leq \ln \left(1+\frac 1n\right) \leq \frac 1n\\\forall n \geq 1, n\in \mathbb N$$  I tried using Taylor expansion but couldn't figure out anything. Any ideas? Thanks. Outlook, POP and PST handling Essentially I have a client who is on hosted exchange and have decided to use POP3 to download the mail (I don't know why they don't use .OST's but anyway), they rebuilt the machine and backed up their .PST file. Now their Outlook was configured to keep mail downloaded on the server for 14days.  Essentially their current PST is fairly complex, many folders and sub folders and so on. So what is the best way to handle it really - create a new Outlook profile on the rebuilt machine and download the mail via POP into a new .PST then just recreate the folders in the new pst and drag and drop the mail via attaching the backed up .pst, recreating the folders etc?  But is their an easier way to do this, maybe pointing the new account to use the original PST, but then that would download all the mail again from the server to that .PST file.  Any ideas on the best way to handle POP3 account rebuilds from scratch when you have a backed up PST? Propane gas fireplace pilot won't light Down vote changed to up vote caused reputation meter to pass daily maximum I just experienced a minor visual bug.  I had an answer that earned 2 down votes and 22+ upvotes, earning me the daily maximum of +200. Upon making some edits to the answer at the behest of the comments, one of the users who down voted changed their vote. Now my reputation meter shows that I gained +202 for the day.    This correctly did NOT affect my reputation, as I still only gained 200, so it is merely a minor display bug.  This appears in the achievements drop down and my reputation tab on my profile.
