4 down vote favorite  I have noticed after deleting an original page in WordPress with lets say a permalink of your_domain.com/contact/ and then trying to recreate the same page with the same name/slug, my WP is generating a "-2" at the end of the link, like: your_domain.com/contact-2/.  I don't understand why, since the original page was deleted. Why is WordPress treating new pages as if the original still exists? There is nothing in 'trash'.  I repeat there is nothing in 'trash'.

How to I clean WP caches, if such a thing even exists?Thank you ahead of time for clearing this up for me.
How to make a WMS GetFeatureInfo request in Leaflet? I am trying to make a WMS GetFeatureInfo request using Leaflet. I can not find something in the documentation to describe this process. Can you please provide with an example demostraing how to do something like this? rent a car, rent out a car, hire a car Do you have advantage when multiple sources give advantage and only one gives disadvantage? As I understand it:   if you have Advantage from two different sources, you simply have Advantage (no stacking) if you have advantage from one source, and disadvantage from one source, they cancel out.     So what if you have advantage from two or more sources, and disadvantage from one source?  My assumption is that you simply have advantage, or put another way, you have Advantage on a roll when the # of Advantages > # of Disadvantages (and vice versa).  Is that correct? How strong is Superman on Krypton? When Superman goes back to visit his home planet (using his ability to travel through time, I guess), is he:    an exceptionally strong and athletic Kryptonian? just an average Kryptonian male? a weakling on account of spending a lifetime in the comparative microgravity of Earth?   A possibly related question: why is Superman so muscular? What kind of weights does he lift to stay in shape?  The answers to  are all about Superman's superpowers on Earth compared with other visitors from Krypton; I'm asking about Kal El without his superpowers.  Clarification: I'm asking about the "classic"  Superman, say late Golden to early Silver Age, roughly 1945-1960. (Yes, I know the concept evolved during those years.) I'm not sure what that would be in terms of "numbered Earths", those came along after my time. I'm pretty sure the Kryptonians of that era had no superpowers in their native milieu, nor would Kal El if he were deported in space-time to his native world. How can I disable the 2nd hard drive in my 27" iMac? What can cause "Discovered - currently not indexed" in the new GWT Confusion between register size, address size, data size I started learning about pointers in C++ and I figured I should educate myself a bit on how memory works and is accessed. I read that when we say a processor is 64-bit, it has a 64-bit register and can access 2^64 address locations. I also read that it can fetch 64/8, so 8 bytes of data at a time, but the data bus is not the same thing as the register right? Do they need to be the same size or does that just happen to be the case usually? And is it the size of the register or the data bus size that determines what we refer to it as, such as 32/64-bit? Also is there a difference between register size and address size? Related questions in "Ask Question" page is better than the search tool Why is $\mathbb{E}[X] = 1 + \sum^\infty_{k=1}\mathbb{P}(X > k)$ true? I'm working through a problem regarding expected values in Markov chains, and at some point it says:     Recall from probability that if $X$ is a positive integer valued random variable, then $\mathbb{E}[X] = 1 + \sum^\infty_{k=1}\mathbb{P}(X &gt; k)$.   I know that by definition $\mathbb{E}[X] = \sum_a a\mathbb{P}(X = a)$, but I can't see how the above equality follows from this, nor am I sure if this is how to approach the problem. Do you ever center AND standardize variables in multiple regression? Do you ever center AND standardize variables in multiple regression? It seems as if standardization would automatically center variables...is this true? I'm trying to use the \citep command in Latex and my document class is elsarticle. The problem is that it displays numbers not authoryear citations in the text which is what I'm looking for. Here are related parts of my code:      \documentclass[preprint,11pt]{elsarticle}      \usepackage{natbib}   ...      \bibliographystyle{plainnat}      \bibliography{ML}   And I'm obviously using the \citep command like this:      I once read \citep{edelman1993magnetic}   And my .bib file looks like this:  @article{wolf2009regional, title={Regional brain activation changes and abnormal functional connectivity of the         ventrolateral prefrontal cortex during working memory processing in adults with attention-deficit/hyperactivity disorder}, author={Wolf, Robert C and Plichta, Michael M and Sambataro, Fabio and Fallgatter,     Andreas J and Jacob, Christian and Lesch, Klaus-Peter and Herrmann, Martin J and     Sch{\"o}nfeldt-Lecuona, Carlos and Connemann, Bernhard J and Gr{\"o}n, Georg and others}, journal={Human brain mapping}, volume={30}, number={7}, pages={2252--2266}, year={2009}, publisher={Wiley Online Library} }   The result looks like:  I once read[1]   I'm looking for a result like this:  I once read(wolf., 2009)   Elsevier is actually looking for:  Text: All citations in the text should refer to:    Single author: the author's name (without initials, unless there is ambiguity) and the year of publication;  Two authors: both authors' names and the year of publication;  Three or more authors: first author's name followed by 'et al.' and the year of publication.    Thanks in advance This problem is from Discrete Mathematics and its Applications  My question is on 9b. I know that the sign represents an element is a member of. (from book)  I know that the O with a slash across it is the empty set which &quot;is a special set that has no elements&quot;. From , I got that the empty set is a subset of all sets, meaning that every member of the empty set(nothing) is also a member of any other set. Based on all of this, for 9b, would {0} contain the empty set because it fundamentally has the elements that consist of the empty set(nothing) or does it physically have to have the empty set? There is no fruit jet pack. I can't get it. How do I get it? I looked at the jetpacks many times. There are none. Which browsers are officially supported by Stack Exchange?  Also, what else is needed in order to use every feature of the site? I would like to set the wallpaper in the login screen (Unity Greeter), how do I do that? Show that the series $\sum(\exp(\frac{(-1)^n}{n})-1)$converges, but not absolutely. Show that the series converges, but not absolutely. $\sum_{n=1}^{\infty}( $exp$(\frac{(-1)^n}{n})-1)$.   My Try:  Let $a_n=$exp$(\frac{(-1)^n}{n})-1$. I was going to use alternating series test because the sequence $\{a_n\}$ is alternating. But $\{|a_n|\}$ is not decreasing to $0$. So, I am stuck now. Can anybody please give me a hint? Setting constraints causes the location of the constrained objects/bodies not be accessible I set up 2 bodies manually &amp; assigned Copy Location constraint to one with respect to another body. Then I set up the keyframe for the guiding body &amp; then I started to view the change in the location of the constrained body. What I noticed in the 3D viewport was the constrained object moves, but when I look into its real position the values are stagnant. Why is that? I was unable to find my answer in previously asked questions by other people !! Why doesn't \makeatletter work inside \newcommand? After hours of banging my brain against my skull, I narrowed down an issue I'm having to the fact that \makeatletter doesn't work inside \newcommand. Commands that I call after \makeatletter are registered as undefined, as if \makeatletter didn't do anything.  Why is this the case?  In the example below, I define two commands. Calling one of them from the document body causes the undefined error, while the other doesn't.  \documentclass[11pt]{book} \usepackage{kvsetkeys}  \newcommand{\commandThatFails}{     \makeatletter \comma@parse{}{} \makeatother }  \makeatletter     \newcommand{\commandThatWorks}{         \comma@parse{}{}     } \makeatother  \begin{document}  Hi there.  \commandThatFails \commandThatWorks  \end{document} Suppose $\displaystyle a_n=\frac{1}{(\text{log}2)^p+(\text{log3})^p+...+(\text{log}n)^p}$ for $n\geq 2$ and $p&gt;0$. For which values of $p$ does $\sum_{n=2}^\infty a_n$ converge?  So, when $p\leq 1$, $\displaystyle a_n\geq \frac{1}{(n-1)(\text{log}n)^p}$ for $n\geq 2$. Let $\displaystyle b_n=\frac{1}{(n-1)(\text{log}n)^p}$. Then $\sum b_n$ diverges since $p\leq 1$. Therefore by comparison test $\sum a_n$ diverges when $p\leq 1$.  When $p&gt;1$, $\displaystyle a_n\leq \frac{1}{(\text{log}n)^p}$. Let $\displaystyle c_n= \frac{1}{(\text{log}n)^p}$. If $\sum c_n$ converges then I will win. But now I am stuck. Is $\sum c_n$ converges? Then how can I prove it? If not how can I conclude the state of convergence of $\sum a_n$ for $p&gt;1$?   Can anybody please help? Customizing the output of Compass sprites
