• How can I get PHP to compile a LaTeX document if it (www-data) can't get access to the required packages?

  - by Mark Jones

  I have a PHP script that compiles LaTeX documents with the use of: exec('cd /path/to/doc && /usr/bin/latexmk -pdf filename.tex'); This is working for some of my LaTeX documents but my latest document doesn't compile and a look at the log reveals: !pdfTeX error: pdflatex (file ecrm1000): Font ecrm1000 at 600 not found ==> Fatal error occurred, no output PDF file produced! Which I have found is the result of LaTeX not being able to see the required font packages. When I run the same compile command under my username the document compiles as it should. So my question is, how can I get PHP (executing as www-data) to get access to the necessary LaTeX packages? I have tried installing the required package under the www-data account using: sudo -u www-data sudo apt-get install texlive-fonts-recommended but it askes for www-data's password, which I don't believe was set by me and isn't anything I've thrown at it. I'm running Ubuntu 12.04 if it's any help.

• Track/Display Array Index As Part Of Cout (C++)

  - by John Smith

  Hi, I have a command line C++ program that lets you enter basic information about a person (ID number, name, age, etc.) and I want to output to a console in the following manner: ------------------------------------------------------------------- Index ID # First Name Last Name Age ------------------------------------------------------------------- 0 1234 John Smith 25 The person objects are stored in an array of Persons and I've overload the ostream (<<) operator to print out all of the fields like you see. The dashed lines and header come from a displayHdg() function. Anyhow, I have not been able to figure out how to get the proper index value for the array. Ideally, I'd like to generate the indices for each line, but all my attempts have failed. The array is looped through and each object printed in the main() function, and the ostream is overloaded in a person class, so I tried to use global variables as well as static variables, and all of those produce incorrect numbering (i.e. show 0, 1 the first time (for 2 objects), then change to 1, 2 on the next display). Any ideas?

• Why would the first call to a KVC setter have an NSTextField instance as the argument?

  - by Stephen

  If I have a NSTextField bound through an NSObjectController to a model object, I would expect the setter of the model object to be called with an NSString as the argument, but instead, I receive the instance of the control that I am bound too the first time I am called. - (NSString *)property { NSLog(@"returning property"); return property; } - (void)setProperty:(NSString *)string { NSLog(@"recieved %@", string) } - (id) init { if (self = [super init]) { property = [[NSString alloc] initWithString:@"value"]; } NSLog(@"property is %@",property"); return self; } (The program doesn't run if you try anything in setProperty, because it tries to send NSString messages to string - which might be an NSTextField.) Console Output: 2010-05-12 14:19:14.096 Trouble[13108:10b] property is enter value 2010-05-12 14:19:14.100 Trouble[13108:10b] recieved <NSTextField: 0x1025210> 2010-05-12 14:19:14.106 Trouble[13108:10b] returning property

• NSUndoManager won't undo editing of a NSMutableDictionary

  - by xon1c

  Hi, I'm experiencing problems with the undo operation. The following code won't undo an removeObjectForKey: operation but the redo operation setObject:ForKey: works. - (void) insertIntoDictionary:(NSBezierPath *)thePath { [[[window undoManager] prepareWithInvocationTarget:self] removeFromDictionary:thePath]; if(![[window undoManager] isUndoing]) [[window undoManager] setActionName:@"Save Path"]; NSLog(@"Object id is: %d and Key id is: %d", [currentPath objectAtIndex:0], thePath); [colorsForPaths setObject:[currentPath objectAtIndex:0] forKey:thePath]; } - (void) removeFromDictionary:(NSBezierPath *)thePath { [[[window undoManager] prepareWithInvocationTarget:self] insertIntoDictionary:thePath]; if(![[window undoManager] isUndoing]) [[window undoManager] setActionName:@"Delete Path"]; NSLog(@"Object id is: %d and Key id is: %d", [[colorsForPaths allKeys] objectAtIndex:0], thePath); [colorsForPaths removeObjectForKey:thePath]; } The output on the console looks like: // Before setObject:ForKey: Object id is: 1184384 and Key id is: 1530016 // Before removeObjectForKey: UNDO Object id is: 2413664 and Key id is: 1530016 I don't get why the Object id is different although the Key id remains the same. Is there some special undo/redo handling of NSMutableDictionary objects? thx xonic

• AJAX call + JQuery Dialog Title changing dynamically

  - by Panther24

  I have an AJAX call which loads an Dialog page, now depending upon the content of the data returned on the AJAX call, I want to change the title of the Window, how do I do that. Here is the snippet of code: var divid = "brHistoryForm"; var url = "getRestoreFiles.action?profileName="+profileName; // Create xmlHttp var xmlHttp = AJAX(); // The code... xmlHttp.onreadystatechange=function(){ if(xmlHttp.readyState==4){ document.getElementById(divid).innerHTML=xmlHttp.responseText; } } xmlHttp.open("GET",url,true); xmlHttp.send(null); $('#brHistoryForm').dialog('open'); jQuery('#brHistoryForm').focus(); document.getElementById('pageTitle').innerHTML = "<h2>"+profileName+" - B&R History</h2>" Here 'pageTitle' is a div. When I run the above piece of code, it opens a dialog window, the action is redirected to a jsp page which is loaded inside the div. It works fine, but the title does not get set :(. I've tried to do the setting of the title in the redirected jsp page, it doesn't work either. Here is the code of that JSP page: <%@page contentType="text/html" pageEncoding="UTF-8"%> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <%@ taglib prefix="s" uri="/struts-tags" %> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>B&R History</title> </head> <body> <table style="width: 100%"> <tr> <td style="width: 40%"> <div id="pageTitle"> <h2>B&R History</h2> </div> </td> </tr> </table> <table id="diskTable" cellpadding="0" cellspacing="0" border="1" class="display"> <thead> <tr> <th>Select</th><th>Operation</th> <th>Source</th><th>Destination</th> <th>Status</th><th>Start Time</th><th>End Time</th> </tr> </thead> <tfoot></tfoot> <tbody> <s:iterator value="restoreFileList"> <tr> <td> <s:if test="%{status.equals('Finished')}"> <input onClick="loadRestoreForm('<s:property value="name"/>', '<s:property value="to_path"/>', '<s:property value="status"/>')" type="radio" name='chk' id="chk" value="<s:property value='id'/>,<s:property value="status"/>" > </s:if> <s:else> <input type="radio" name='chk' id="chk" value="<s:property value='id'/>,<s:property value="status"/>" disabled> </s:else> </td> <td> <s:if test="%{br_type == 0}"> Backup </s:if> <s:else> Restore </s:else> </td> <td><s:property value="from_path"/></td> <td><s:property value="to_path"/></td> <td><s:property value="status"/></td> <td><s:property value="start_time"/></td> <td><s:property value="end_time"/></td> </tr> </s:iterator> </tbody> </table> </body> </html> Any help would be appreciated.

• MVC2 IModelBinder and parsing a string to an object - How do I do it?

  - by burnt_hand

  I have an object called Time public class Time{ public int Hour {get;set;} public int Minute {get;set;} public static Time Parse(string timeString){ //reads the ToString()'s previous output and returns a Time object } override protected string ToString(){ //puts out something like 14:50 (as in 2:50PM) } } So what I want is for the automatic model binding on the Edit or Create action to set this Time instance up from a string (i.e. feed the Parse method with the string and return the result). The reason I am doing this is that I will have a DropDownList with selectable times. The value of each option will be the parser readable string. Can anyone provide an example BindModel method from the IModelBinder interface?

• Given two lines on a plane, how to find integer points closest to their intersection?

  - by Lukasz Lew

  I can't solve it: You are given 8 integers: A, B, C representing a line on a plane with equation A*x + B*y = C a, b, c representing another line x, y representing a point on a plane The two lines are not parallel therefore divide plane into 4 pieces. Point (x, y) lies inside of one these pieces. Problem: Write a fast algorithm that will find a point with integer coordinates in the same piece as (x,y) that is closest to the cross point of the two given lines. Note: This is not a homework, this is old Euler-type task that I have absolutely no idea how to approach. Update: You can assume that the 8 numbers on input are 32-bit signed integers. But you cannot assume that the solution will be 32 bit.

• PHP Dynamic Breadcrumb

  - by Adrian M.

  Hello, I got this code from someone and it works very well, I just want to remove the link from the last element of the array: //get rid of empty parts $crumbs = array_filter($crumbs); $result = array(); $path = ''; foreach($crumbs as $crumb){ $path .= '/' . $crumb; $name = ucfirst(str_replace(array(".php","_"),array(""," "), $crumb)); $result[] = "<a href=\"$path\">$name</a>"; } print implode(' > ', $result); This will output for example: Content Common File I just want a to remove the link from the last item - "File" to be just plain text.. I tried myself to count the array items and then if the array item is the last one then to print as plain text the last item.. but I'm still noob, I haven't managed to get a proper result.. Thank you!

• Combining regroup with get_foo_display in Django templates

  - by shacker

  I'm using the regroup template tag to group queryset output on a Choices field. In the model: RESOURCE_TYPES = ( ('tut','External tutorial'), ('read','Additional reading'), ('org','Company or organization'), ) restype = models.CharField('Resource type',max_length=6,choices=RESOURCE_TYPES) in the view: resources = Resource.objects.filter(tutorial=tutorial) in the template: {% regroup resources by restype as resource_list %} {% for type in resource_list %} <h3>{{type.grouper}}</h3> So type.grouper renders as 'tut' or 'org' on the page, rather than the long form. Normally you would use the get_foo_display syntax to get at the value of the choice, rather than the key. But the value doesn't seem to be available after going through regroup. There's no way I can find to use get_foo_display on {{type.grouper}}. It makes sense when you think about it, but what's the workaround? Thanks.

• Why does it NOT give a segmentation violation?

  - by user198729

  The code below is said to give a segmentation violation: #include <stdio.h> #include <string.h> void function(char *str) { char buffer[16]; strcpy(buffer,str); } int main() { char large_string[256]; int i; for( i = 0; i < 255; i++) large_string[i] = 'A'; function(large_string); return 1; } It's compiled and run like this: gcc -Wall -Wextra hw.cpp && a.exe But there is nothing output. NOTE The above code indeed overwrites the ret address and so on if you really understand what's going underneath.

• How do partialviews work in asp.net MVC when passing parameters back?

  - by Rob Ellis

  I have a page with a partialview on it which is a list of items. I have a button on it which shows the next 5 items. This is done via ajax:- using (Ajax.BeginForm("ShowUpdates", new AjaxOptions() { UpdateTargetId = "statusUpdateContainer", InsertionMode = InsertionMode.InsertAfter })) { <input type="submit" class="formbutton" value="Show More" style="width:100%;"/> } My partial view controller: [HttpPost] public ActionResult ShowUpdates(string page, string pagesize) { //get data code hidden here return PartialView("_statusUpdates"); } My question is that I need the 'page' variable to increment each time someone presses the form button which is contained within the partialview. How do I keep track of that variable?

• Unable to remove package from Delphi 2005

  - by Robo

  I needed to reinstall a package, DrRX.bpl. I removed it from the package list, and trying to install a newer version of the same package. I've replaced the old component's dir with the new one. When I open the new DrRX.bpl and click install, I get the error "Package C:\Program Files\Borland\BDS\3.0\components\rx work\output\DrRx.bpl cannot be installed because another package with the same basename is already loaded (DrRx.bpl)" I cannot find any reference to DrRX in my package list, DrRX does not appear in the Tool Palette. How do I locate where Delphi thinks this is installed, and remove it, so I can reinstall the package?

• Convert CString to string (VC6)

  - by Yan Cheng CHEOK

  I want to convert CString to string. (Yup. I know what am I doing. I know the returned string will be incorrect, if CString value range is outside ANSI, but That's Is OK!) The following code will work under VC2008. std::string Utils::CString2String(const CString& cString) { // Convert a TCHAR string to a LPCSTR CT2CA pszConvertedAnsiString (cString); // construct a std::string using the LPCSTR input std::string strStd (pszConvertedAnsiString); return strStd; } But VC6 doesn't have CT2CA macro. How I can make the code to work as well in both VC6 and VC2008?

• assistance with classifying tests

  - by amateur

  I have a .net c# library that I have created that I am currently creating some unit tests for. I am at present writing unit tests for a cache provider class that I have created. Being new to writing unit tests I have 2 questions These being: My cache provider class is the abstraction layer to my distributed cache - AppFabric. So to test aspects of my cache provider class such as adding to appfabric cache, removing from cache etc involves communicating with appfabric. Therefore the tests to test for such, are they still categorised as unit tests or integration tests? The above methods I am testing due to interacting with appfabric, I would like to time such methods. If they take longer than a specified benchmark, the tests have failed. Again I ask the question, can this performance benchmark test be classifed as a unit test? The way I have my tests set up I want to include all unit tests together, integration tests together etc, therefore I ask these questions that I would appreciate input on.

• HTML element to use as a Javascript message display

  - by javanix

  I have a message display field on my website that I'd like to change the value of via JS. I've been using just a textfield, disabling it, and modifying the value via a JS function (after using a little CSS to make it not look like a text field): <input type="text" id="message" style="background: white; color: black" size="50" disabled> There has to be a better way (for instance, formatting is tricky whenever the message runs over the specified size), but I can't think of it off the top of my head. Can anyone point me in a better direction? Thanks! FYI: I am doing a timer function which I'd like to look something like "HH:MM:SS | 'my message here'"

• How should platform specific lib files be named?

  - by Scott Langham

  Hello, I'm working on a C++ project that produces a lib that other teams use. It's being produced in a few different flavours: Win32 Debug Win32 Debug Static Win32 Release Win32 Release Static x64 Debug x64 Debug Static x64 Release x64 Release Static I'm wondering what the best wisdom is on how to name the dlls and what arguments are for different naming conventions. Do I output the libs into different directories, or do I append some letters on the end of the lib to differentiate them, or something else? One concern is that if I use directories, but don't give all the libs different names, users of the library will have problems where they accidentally use the wrong lib. Are these concerns valid? Thanks very much.

• RedirectStandardInput crashes program

  - by Roman

  Hi, the following code is to open a console application (which uses pdcurses for output, nothing special): myProcess.StartInfo.FileName = "some.exe"; myProcess.StartInfo.UseShellExecute = false; myProcess.StartInfo.CreateNoWindow = false; myProcess.StartInfo.RedirectStandardInput = true; myProcess.Start(); The Problem is that it opens the designated window but directly closes it (it's barely visible). Starting the program without RedirectStandardInput works. The problem is that it does not throw an exception nor any error-message. What is wrong with my code? How can I write input to the program? Thanks.
