I was on  and even though it showed some questions, the counter was in 0:
There aren't any new or popular questions. There are tons of questions in both of those tabs but the question count is 0 for both of those when I try to view them in the expanded view.
Is "chutzpah" used by non-Jewish English speakers? Can I convert a C# string value to an escaped string literal? In C#, can I convert a string value to a string literal, the way I would see it in code? I would like to replace tabs, newlines, etc. with their escape sequences. If this code: Console.WriteLine(someString);  produces: Hello World!  I want this code: Console.WriteLine(ToLiteral(someString));  to produce: \tHello\r\n\tWorld!\r\n I found some articles related to this, but they were not sufficient for me. I want to know how the localhost works and why is it the same on many different machines?   How does the localhost block the access to the website when we use it in the host file to block the website? How to best determine if a bike will fit without riding it I am using field image to insert image into article. The image can't show in article body.   How do I insert the image into article? How to execute sudo commands with Expect & send commands in bash script? Sequence of a product of functions in $L^p. L^q$ with $p,q$ conjugate The question is: if $f_i$ is a sequence of functions in $L^p$ converging to $f$ and $g_i$ a sequence in $L^q$ converging to $g$ show that $f_ig_i$ converges to $fg$ in $L^1$ for $p,q$ finite and $\frac{1}{p}+\frac{1}{q}=1$. Does this result hold if $p=1, q=\infty$?  So I think I showed the first part. $||f_ig_i-fg||_1=||f_ig_i-f_ig+f_ig-fg||_1\leq||f_ig_i-f_ig||_1+||f_ig-fg||_1 = ||f_i(g_i-g)||_1+||g(f_i-f)||_1\leq||f_i||_p||g_i-g||_q+||g||_q||f_i-f||_p$   (by Holder's inequality) which goes to $0$ as $i\rightarrow\infty$.  However the second part of the question throws me off because I don't see why this proof doesn't work just as well for $p=1,q=\infty$.  Am I missing something? Does the second part also hold? With arrays, why is it the case that a[5] == 5[a]? Software was blocked from opening because it is not from an identified developer I went to run LibreOffice on my OS X 10.9 and it would not let me install it. It said it was from an unidentified developer. I'm aware of the security features of the Mac and went to System Preferences to allow the software to run.   When I opened this setting I saw a button that said, '"LibreOffice" was blocked from opening because it is not from an identified developer.' and there was a button next to it that said "Open Anyway". I clicked this button and nothing happened. I clicked it multiple times, like a hundred, out of frustration. Is there something else I need to do? Could someone verify this is not a bug?   UPDATE: I've included the photo below of what my System Preferences screen looked like and the button I pushed that didn't work.  UPDATE II: So I tried opening the application again and went into the system preferences and pressed the "Open Anyway" button again and nothing happened at first but a few minutes later while I was typing an email something flashed across my screen, possibly another dialog (or more likely a chewpacabra), but it quickly disappeared and the next thing I know LibreOffice launched! load a file and read the information I want to open an Excel file through an Apex dialog box, then browse the information in my file line and display it with visualforce. I show you my code  public class ImportExcel {       public String fileName{get; set;}     public Blob contentFile{get;set;}     public String[] csvFileLines{get;set;}     public List&lt;String&gt; acclist{get;set;}     public String[] data{get;set;}     public ImportExcel(){         csvFileLines = new String[]{};         acclist = New List&lt;String&gt;();      } public void readFile(){         try         {             fileName=contentFile.toString();         }catch(Exception e){         ApexPages.Message myMsg = new ApexPages.Message(ApexPages.Severity.FATAL,'Please upload a valid CSV document');         ApexPages.addMessage(myMsg);              return ;          }         csvFileLines=fileName.split('\n');          system.debug(csvFileLines);         for(Integer i=0;i&lt;csvFileLines.size();i++){             data=csvFileLines[i].split(',');             acclist.add(data[i]);         }     } }   Once I execute my code, it puts me this error:     13:52:13:012 VARIABLE_ASSIGNMENT   [15]|e|"common.apex.runtime.impl.ExecutionException: BLOB is not a   valid UTF-8 string"|0x4e4728 When should I create a new tag? How do I request a new tag if I don't have enough rep? Can someone please create the tag  on our site? We need to have it because        Foo is a recent/upcoming release / edition / model / episode of a popular, established OS / board game / bike brand / TV show   Foo is a hot new language / ingredient / game   we're currently using some other tag for questions about Foo, but it's causing ambiguity with a separate thing that's also named Foo      This is not a joke post. We get a lot of feature requests that ask for this or that tag to be created, and every time, a discussion ensues wherein people explain that there is no "tag creation department" and that community members create tags just by using them. I'm posting this "question" so that future requests of that type can be closed as a duplicate of this, saving time and eliminating redundant conversations for everyone involved.     See also: Is there a Windows 10 Hotkey or Shortcut for switching to a specific display? I have my Windows 10 desktop computer connected to two displays through HDMI - one monitor and one TV, which I can toggle through with Windows Key+P as described in the accepted answer to .  However, I was wondering if there was some hotkey, shortcut, or button combination I could use sort of like a "Virtual KVM Switch" that lets me select one display or another specifically, without needing to cycle/toggle through other displays. C++11 does not deduce type when std::function or lambda functions are involved Is there a single word to describe a solution that hasn't been optimized? I am working with some code, and I would like to describe the difference in its performance when it is optimized versus when it is not optimized. Unfortunately, I can't find a word to describe the code before it is optimized; "sub-optimal" might work, but I want to emphasize that this is the first iteration of the code. If "unoptimized" were a word, I would use that, but I haven't found any references to it in any dictionary.  Perhaps "raw" or "original"? I just wanted to ask whether there is any command which would work on common shells (bash, dash, kornshell)? It is supposed to check if the line variable contains any part of the path.  if [[ $line =~ "$PWD"$ ]] ;then PHP PCRE (regex) doesn't support UTF-8? DOM event precedence What order of precedence are events handled in JavaScript?  Here are the events in alphabetical order...   onabort - Loading of an image is interrupted onblur - An element loses focus onchange - The user changes the content of a field onclick - Mouse clicks an object ondblclick - Mouse double-clicks an object onerror - An error occurs when loading a document or an image onfocus - An element gets focus onkeydown - A keyboard key is pressed onkeypress - A keyboard key is pressed or held down onkeyup - A keyboard key is  released onload - A page or an image is  finished loading onmousedown - A mouse button is  pressed onmousemove - The mouse is moved onmouseout - The mouse is moved off  an element onmouseover - The mouse is moved  over an element onmouseup - A mouse button is  released onreset - The reset button is  clicked onresize - A window or frame is  resized onselect - Text is selected onsubmit - The submit button is  clicked onunload - The user exits the page   What order are they handled out of the event queue?  The precedence is not first-in-first-out (FIFO) or so I believe. i have a huuuuge problem.  Created a snapshot and image from my instance...instance has 1000GB of disk.  Now i need to reduce it but everytime i try to create an image or a snapshot from that, i get the same error "Disk need to be at least 1000GB".  There is a way to reduce disk size directly on instance? Some workaround? uint color;  bool parsedhex = uint.TryParse(TextBox1.Text, out color);  //where Text is of the form 0xFF0000 if(parsedhex)    //...   doesn't work. What am i doing wrong?
