An example of a regular function over an open set NewForm.aspx disappeared Pokemon Go login issues after update I downloaded the July 30th update for Pokemon Go and when I open the app I'm prompted to login, But once I login, it redirects me to this page on Cookies::     If I click "Done" in the top left, it prompts me to login again! I've tried reinstalling the game, restarting my phone, etc. I can't much enable Cookies on the inline Safari browser. It doesn't make sense, and cookies are on in Safari (because I don't use Safari and they're enabled by default).  How can I fix this? individual tick label style with pgfplots given the following code, I want to modify the tick labels in such a way, that for negative values of x, the labels are located above the x-axis. How can I realize this?  \documentclass{report} \usepackage{pgf} \usepackage{pgfplots} \pgfplotsset{compat=newest} \pgfplotsset{plot coordinates/math parser=false} \begin{document} \begin{tikzpicture} \begin{axis}[% axis x line=middle, axis y line=middle, width=10cm, height=10cm, scale only axis, xmin=-5, xmax=5, xtick={-4, -2, 0,  2,  4}, xticklabels={$-4\pi$, $-2\pi$, $0$, $2\pi$, $4\pi$}, extra x ticks={-4, -2}, ymin=-1.4, ymax=1.4, ytick={-1,  0,  1}] \end{axis} \end{tikzpicture}% \end{document} Can anyone provide some pseudo code for a roulette selection function? How would I implement this:    I don't really understand how to read this math notation. I never took any probability or statistics. Cite_key instead of a number, what is going on?

I noticed one thing: the textareas where you write your comments/answers are very buggy. I'm using a Samsung Galaxy S2, with the standard Android browser (Android version 4.1.2). There are a number of things that aren't working when typing your comment/answer.   Automatic spacing with Swype is disabled (however this might be because of Swype, not the site). Text navigation buttons (step left, step right, select text, copy text etc.) doesn't work with the on-screen keyboard, and selecting text by holding your finger over text is extremely difficult. When you paste something it always seems to be pasted at the top of your text, no matter where you try to paste it. Replying to another comment ("@Example User") does not show suggested people to reply to, like the full site does.   Is there anything I can do to solve these issues/bugs, or is it in the hands of Stack Overflow itself, and if so, should it be looked into?  Edit: I was using the mobile version of the site when noticing these bugs. Here is my problem: I've got a dialog with some parameters that the user can change (via a spinner for example). Each time one of these parameters is changed, I launch a thread to update a 3D view according to the new parameter value.  If the user changes another value (or the same value again by clicking many times on the spinner arrow) while the first thread is working, I would like to abort the first thread (and the update of the 3D view) and launch a new one with the latest parameter value.  How can I do something like that?  PS: There is no loop in the run() method of my thread, so checking for a flag is not an option: the thread updating the 3D view basically only calls a single method that is very long to execute. I can't add any flag in this method asking to abort either as I do not have access to its code. I often see "replace with" and "replace by" used interchangeably, but this doesn't sound right to me:     I replaced that component by this one.   I would use "with" in such a sentence. "By" only seems reasonable in passive, although "with" sounds like it would there work too:     That component was replaced by this one.   That component was replaced with this one.   In my native language, the equivalent of "replace by" can only be used in passive, and even then it's a bit weird unless a person is the object replacing something – perhaps this affects my judgment?  Web searches haven't come up with anything conclusive; the results are contradictory and speculative at best.  Are "replace with" and "replace by" interchangeable in active context? What about passive? Are there stylistic reasons to prefer one over the other? Error 404 : While using flag Multiples of an irrational number forming a dense subset I'm not a resident of USA. But I work on a cruise ship which required me to have C-1/D visa. I am leaving USA and traveling to Mexico but I will have a connecting flight somewhere in another US airport with 1-2 hours waiting for connecting flight to Mexico.   Do I need B1/B2 visa for that? Or my transit visa C-1/D will be enough as long as I am leaving USA? Modelling the number of apples an orchard yields with diminishing returns per tree This is   in the University of Washington's precal book.  Sylvia has an apple orchard. One season, her 100 trees yielded 140 apples per tree. She wants to increase her production by adding more trees to the orchard. However, she knows that for every 10 additional trees she plants, she will lose 4 apples per tree (i.e., the yield per tree will decrease by 4 apples). How many trees should she have in the orchard to maximize her production of apples?  Instructing a precal class, I walked through my approach to answering this in class (without preparing) and ended up doing something strange that may have confused the students. How would you clearly explain a way to get the function for the number of apples that we are trying to maximize? More generally, how would approach answering this question? It'd be nice to collect a some different approaches to demonstrate to my students that there is not a single rigid correct way to solve a problem. Save text area to file I want to create a table like this using Latex        ---------------------------------       |               sets            |       ---------------------------------       | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | --------------------------------------- | I1  | * |   | * | * |   | * |   | * | ---------------------------------------   Here is what I wrote  \begin{table} \caption{Multiprogram sets} \label{multiprogram}  \begin{tabular}{| c | c | c | c | c | c | c | c | c |}   \cline{3-9}   \multicolumn{8}{}{}    &amp;   Sets  \\   \hline   \multicolumn{1}{}{}   &amp; 1 &amp; 2 &amp;  3 &amp; 4 &amp; 5 &amp;  6 &amp; 7  &amp; 8 \\   \hline    astar         &amp;  &amp; * &amp;  &amp; * &amp;  &amp;  &amp; * &amp;   \\   \hline  \end{tabular} \end{table}   But it doesn't work!
