I wanna insert only a left bar like \left | without the closing right bar.  Why? I want to use it as separator of calculation hints.  $a * b = c | :b\\ a = \frac{c}{b}$  and so on.   It must be a left bar and not only | or \vert so that it is scaled in height.
I have a very long equation that must be separated into two lines, and it has several pairs of nesting \left \right delimiters. Unfortunately, it seems that they need to be on the same line in order for them to work.  Also I'm using the align environment because I need the aligning functionality. Is there a way to have the size of delimiters automatically adjusted over multiple lines?
I assume that the multimeter should read 2A, why is it only 0.358A? If this is how it is supposed to be, why? If I add a load, how do I measure that this load is being drawn, does the multimeter need to be in series? I'm going to encrypt the characters Zhu, and decrypt them using RSA. I'm using the public key $\{e, n\}$ and private key $\{d, n\}$. The values of $e$, $d$ and $p$ I get from my textbook: $e = 17$, $d = 53$, $n = 77$.  It works fine when the number is smaller than 76, but in my example below, it doesn't work:  z = 90  h = 104  u = 107  e = 17 d = 53 n = 77  print z,h,u  c_z = z ** e % n c_h = h ** e % n c_u = u ** e % n  print c_z, c_h, c_u  p_z = c_z ** d % n p_h = c_h ** d % n p_u = c_u ** d % n  print p_z, p_h, p_u   The outputs are:  90 104 107 62 69 46 13 27 30     Do you have any idea what's going wrong? I have a managed C# dll that uses an unmanaged C++ dll using DLLImport. All is working great. However, I want to embed that unmanaged DLL inside my managed DLL as explain by Microsoft there:    So I added the unmanaged dll file to my managed dll project, set the property to 'Embedded Resource' and modify the DLLImport to something like:  [DllImport("Unmanaged Driver.dll, Wrapper Engine, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null", CallingConvention = CallingConvention.Winapi)]   where  'Wrapper Engine' is the assembly name of my managed DLL 'Unmanaged Driver.dll' is the unmanaged DLL  When I run, I get:     Access is denied. (Exception from HRESULT: 0x80070005   (E_ACCESSDENIED))   I saw from MSDN and from  that's supposed to be possible... I met a guy on a sugar daddy dating site and we talked, I told him my situation and he said he would help.   He asked for my bank account information and I told him you can use cash app or PayPal to go through. He said his account manager deals with his finances. So I set up an account with a bank that I don’t use so that my primary account isn’t used.  Eventually he was in the process of sending me money and we had agreed on a amount that wasn't crazy. But then he asked for my address and I asked why and he said just wondering. Then said he wanted to send me a surprise for being his baby. Which I didn’t give.  Then later on he sent the money and said he sent me a bonus and that I was supposed to use that to pay his mothers caregiver, which he didn’t mention until after.  I kept questioning him and he was saying that he works in construction and he’s trusting me to carry out the errand. Then he said don’t let him down and I asked him if he was threatening me and he kept saying I need this done but didn’t really answer my question.  Am I being scammed? I’m about to change my password but is this a scam? Why shouldn't I use "Hungarian Notation"? What "exactly" happens when someone turns to the Dark Side? Why are one-way plane tickets more expensive than return tickets? How do I update jQuery to the latest version I can download? I am using my notes app on OSX 10.11.5 and iOS 8. For the most part, things are working, but I am noticing that many of my older notes are not searchable. When I type something in the search box, these older notes do not appear in search results even if there is a match. However, if I edit a note or create a new one, it is fully searchable.  My guess is that somehow the search indexes for my notes got corrupted. Is there any way to fix this or rebuild the indexes? Explain why $\mathbb{Z \times Z}$ and $\mathbb{R \times R}$ is not a field As the title says. I use, among other things, the following in my lstset:  framerule=1pt, frame=tblr   Some places a page break happens in the middle of my \lstlisting. Fine. But sometimes the whole code of the listing appears on one page, but the bottom frame appears on the top of the next page!    I know that I can float a particular listing, but I have a long document with many listings, and I don't want to float all of them; Most of them also need to be exactly where they are declared. That they are broken over a page doesn't bother me that much.  Is there something that can stop this from happening, without me needing to adjust each individual listing?   had the same problem, but fixed it by removing spaces in front of keywords in a custom language definition. I too have a custom language definition, but his solution doesn't help me. I managed to recreate the situation without a custom language.  Edit and MWE  I managed to reproduce it in a minimal working example. 's a pastebin, if that's helpfull.  \documentclass[UKenglish,a4paper,11pt]{report} \usepackage{babel}  %% Adjustments \addtolength{\topmargin}{-1\baselineskip} \addtolength{\textheight}{4\baselineskip} \pretolerance = 2000 \tolerance = 5000   \hbadness = \tolerance  %% Smaller font \usepackage{mathptmx}  %% LISTINGS \usepackage[final]{listings} \lstset{     xleftmargin=1.5em,     framexleftmargin=1em,     framextopmargin=0.5ex, %%  THE FRAME:     framerule=1pt,     frame=tblr }  %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%  \usepackage{lipsum}     % for demo \begin{document} \subsubsection{Lorem}   % some fiddling to get the "wrong spacing just right": \lipsum[1-3] \subsubsection{Ipsum}  \lipsum[1] and then some text  \begin{lstlisting} Here is a listing with three lines of code; The bottom border is placed on the next page! \end{lstlisting}  Can you believe it..?! \end{document}   This MWE is rather long. My document inputs most of the listings stuff from files written by others, so I'm not sure what all of it does. If anyone sees some lines that they are sure is irrelevant, feel free to take it out of the MWE.  "Fun fact"  An equally silly situation occurs if you remove \usepackage{mathptmx}: The whole code listing will then appear on the new page, except for the top frame which is left on the bottom of the first page! What TV movie had lost space cadets who piloted yellow tripod robots, and a squid bad guy? I'm trying to find a movie I watched on TV, probably in the 90s. I think it was a made-for-TV movie.  It was about a ship with an AI. The ship was crewed by young adults. I think they were cadets?   There was an accident (like a warp drive malfunction) and they end up in another part of space where they meet a female alien whose ship had been shot down.  I remember they had manned robots they would pilot and they took them to a planet to get upgraded and they are attacked by more manned robots. They had three legs and they were yellow, I think.  I also remember the baddie had a holo-projector or something like that which allowed him to change his appearance. He commanded a massive fleet and he worked for someone he spoke to in a video chat that looked like a squid. What effect does serial downvoting have on my rep cap? So I was the victim of serial downvoting the other day, and just had it automagically reversed. Rather than simply removing the previous votes, I was given a bonus lump of rep with the reason "serial downvote reversal". The downvotes and the bonus show up on different days. Since a whole day's quota worth of downvotes equates to quite a fraction of my daily rep cap, what happens in the following circumstances?   I get 200+ rep on a particular day, but I am serial downvoted (later reversed) back to under 200. Does this day count as reaching cap? I get 200+ rep the next day, and I am also credited back the rep. Is the rep bonus immune to the rep cap in the same way bounties are? On the day I get my rep bonus, it is enough to take me to 200 rep. Does this count as capping? How do I iterate over the words of a string? Orbiting a specific point - Orbiting Camera When I receive a message on an SE post, I get a notification like this:    If I double tap this notification, the SE application opens, but my feed is empty approximately half the time. It looks like this:    If I refresh the feed (slide from the top), the feed does refresh and shows the new notification.   The notification, above, leads to  comment.  I haven't figured out the pattern yet, but this occurs roughly half the time I open a notification. It's occurred for chat messages, comments and answers - but not consistently. I have received notifications for the same post (for example, the two comments after the one linked above) that do not show an empty feed. But, a chat message barely 10 minutes later will show the empty feed again.  I am utilizing the beta app - version 1.0.72 on Android 5.0.1. what is the difference between - I make it to go and I make it go? What is the difference between sentences like these:     I make it to go.   I make it go.   or     You make me to cry.   You make me cry. I don't understand at all why:  \begin{equation} \sum\limits_{n=0}^\infty p_n x^n = \prod\limits_{k=1}^\infty (1-x^k)^{-1} \end{equation}  Where $p_n$ is the number of partitions of $n$. Specifically how can the sum of positive numbers ever be factored into a fraction or factors to the $-1$ power? Is this something purely notational or am I missing something big?  Thanks for all the help! What exactly is a photon? Can I apply for two Schengen visas if I have two subsequent trips within a short period? I am traveling to Germany on May 1st for an exhibition for which I have already obtained a visa and its validity is up to May 13th. I am returning on May 12th and then traveling on May 17th to UK, and from UK to Switzerland for vacation with family. As time is very short for applying for a Schengen visa again after returning on the 12th with May 13-14 being a Saturday and Sunday, can I apply for Schengen visa again and can I get 2 valid Schengen visa?
