  • calculate intersection between two segments in a symmetric way

    - by Elazar Leibovich
    When using the usual formulas to calculate intersection between two 2D segments, ie here, if you round the result to an integer, you get non-symmetric results. That is, sometimes, due to rounding errors, I get that intersection(A,B)!=intersection(B,A). The best solution is to keep working with floats, and compare the results up to a certain precision. However, I must round the results to integers after calculating the intersection, I cannot keep working with floats. My best solution so far was to use some full order on the segments in the plane, and have intersection to always compare the smaller segment to the larger segment. Is there a better method? Am I missing something?

  • JSON in an AJAX request

    - by Josh K
    I have a PHP API I'm working with that outputs everything as JSON. I need to call one of the API methods and parse it out using an AJAX request. I am using jQuery (though it shouldn't matter). When I make the request it errors out with a "parsererror" as the textStatus and a "Syntax Error: invalid label" when I make the request. Simplified code: $.ajax ({ type: "POST", url: "http://mydomain.com/api/get/userlist/"+mid, dataType: "json", dataFilter: function(data, type) { /* Here we assume and pray */ users = eval(data); alert(users[1].id); }, success: function(data, textStatus, XMLHttpRequest) { alert(data.length); // Should be an array, yet is undefined. }, error: function(XMLHttpRequest, textStatus, errorThrown) { alert(textStatus); alert(errorThrown); }, complete: function(XMLHttpRequest, textStatus) { alert("Done"); } });

  • Best way to implement a 404 in ASP.NET

    - by Ben Mills
    I'm trying to determine the best way to implement a 404 page in a standard ASP.NET web application. I currently catch 404 errors in the Application_Error event in the Global.asax file and redirect to a friendly 404.aspx page. The problem is that the request sees a 302 redirect followed by a 404 page missing. Is there a way to bypass the redirect and respond with an immediate 404 containing the friendly error message? Does a web crawler such as Googlebot care if the request for a non existing page returns a 302 followed by a 404?

  • Sphinx non-fulltext, integer only search

    - by James
    Hello guys, I've got a few tables that literally only hold integers, no "words" and for some reason Sphinx is unable to hold this data in it's library. Just returns "0 bytes" errors for these indexes. Is it possible to do this? If so, how? Below is an example from my Sphinx.conf for one that fails. source track { type = mysql sql_host = host sql_user = user sql_pass = pass sql_db = db sql_port = port sql_query = SELECT id, user, time FROM track; sql_attr_uint = user sql_attr_uint = time sql_query_info = SELECT * FROM track WHERE id=$id } index track { source = track path = /var/lib/sphinx/track docinfo = extern charset_type = utf-8 min_prefix_len = 1 enable_star = 1 }

  • Push origin master error on new repository.

    - by thaiyoshi
    I just started using git with github. I followed their instructions and ran into errors on the last step. I'm checking in an existing directory that isn't currently source-controlled (project about a week old). Other than that, my use case should be pretty run of the mill. Here's what's happening: $ git push origin master error: src refspec master does not match any. fatal: The remote end hung up unexpectedly error: failed to push some refs to '[email protected]:{username}/{projectname}.git' Github's instructions: Global setup: Download and install Git git config --global user.name "Your Name" git config --global user.email {username}@gmail.com Next steps: mkdir projectname cd projectname git init touch README git add README git commit -m 'first commit' git remote add origin [email protected]:{username}/{projectname}.git git push origin master

  • msvsmon is locking up my pdbs

    - by Sam Saffron
    During developement of my media center plugin (which has a few custom build steps to gac stuff and such) msvsmon has a rather annoying behaviour. First compilation usually goes well, but subsequent compilations complain about myplugin.pdb being locked Error 1 Unexpected error creating debug information file 'C:\Users\sam\source\myfile.PDB' -- 'C:\Users\sam\source\obj\Debug\myfile.pdb: The process cannot access the file because it is being used by another process. If I exit VS and nuke the object directory, I am able to compile again. Also, if I kill off msvsmon.exe I am able to compile again (but can not debug) Has anyone seen this error? Are there any workarounds? I already disabled live semantic errors, just in case.

  • VS 2010 Class Diagram Error "The type cannot be edited..."

    - by Eric J.
    A few of the classes on a VS 2010 class diagram are displayed with a red title. The Class Details window shows all of the methods, properties, fields and correctly shows no events. However, there's an entry under each of methods, properties, fields and events that states where the name should be: "The type cannot be edited because the source code file contains an error." However, the source file builds with no errors or warnings. Anyone seen this? Any idea how to fix it?

  • C++ Templates: implicit conversion, no matching function for call to ctor

    - by noname
    template<class T> class test { public: test() { } test(T& e) { } }; int main() { test<double> d(4.3); return 0; } Compiled using g++ 4.4.1 with the following errors: g++ test.cpp -Wall -o test.exe test.cpp: In function 'int main()': test.cpp:18: error: no matching function for call to 'test<double>::test(double) ' test.cpp:9: note: candidates are: test<T>::test(T&) [with T = double] test.cpp:5: note: test<T>::test() [with T = double] test.cpp:3: note: test<double>::test(const test<double>&) make: *** [test.exe] Error 1 However, this works: double a=1.1; test<double> d(a); Why is this happing? Is it possible that g++ cannot implicitly convert literal expression 1.1 to double? Thanks.

  • How to implement dynamic queries for MNesia?

    - by Kerem
    I'm trying to implement a function that generates dynamic queries for MNesia. For example, when function is called with these arguments; dyn_query(list, person, [name, age], ["jack", 21]) I want to query MNesia to list items whose name is "jack" and age is 21 in person table. I've tried to implement this by using qlc:q(ListComprehension) and qlc:string_to_handle("ListComprehension"). First failed because of compile errors, compiler didn't let me to use functions instead of ListComprehentions and variables instead of record names like "Item#Table.Member". Second failed, because erl_eval couldn't handle records and throwed exceptions like {undefined_record, person}. Which method should I use? How could i solve these problems? Or should I use a different method? Thanks.

  • Shoes and Gems and how to get them working.

    - by Pselus
    I have seen this question asked all over the internet and answered in many different ways. None of them seem to be working for me. I am trying to get Gems to work in Shoes (specifically the gem Mechanize). Whenever I use the code: Shoes.setup do gem 'mechanize' end require 'mechanize' It gives me the popup that says it is installing native extensions and sits at that screen for 30 minutes and longer (I've only ever waited as long as 30 minutes). I have seen people say that you should be putting the .gem files in ~/.shoes/+gem/gem (on OS X) but that hasn't worked for me. Neither has putting the source code for the gem there. On another odd note, both the gems RedCloth and Nokogiri come with Shoes...but using the above code for them gets me No such file to load errors for both of them. Anyone have any expertise in this area and can help me out?

  • Custom QGraphicsItems not compiling and give object is is private error

    - by bahree
    Hi, I am trying to create a Custom QGraphicsItem button as shown by Fred here. The code which he posted can be found here. The problem is when I try and compile the code I get the following two errors: /usr/include/qt4/QtGui/qgraphicsitem.h ‘QGraphicsItem::QGraphicsItem(const QGraphicsItem&)’ is private /usr/include/qt4/QtCore/qobject.h ‘QObject::QObject(const QObject&)’ is private Here is the code snippet which essentially is the same as that in the sample above. The error is on the class deceleration. class MyButton : public QObject, public QGraphicsItem { Q_OBJECT Q_INTERFACES(QGraphicsItem) public: MyButton(QGraphicsItem *parent = 0); MyButton(const QString normal, const QString pressed = "", QGraphicsItem *parent = 0); .... } Interestingly the other sample as shown here works fine. The sample code for that can be found here. Any idea what is wrong? Thanks in advance.

  • Calling methods within same Javwscript class [Prototype]

    - by eldeejay
    I've created a class in Javscript using the prototype Class.Create complete with the initialize function and a few other functions. However, in one of my functions I want to reference another function in the same class, but cannot seem to get the syntax correct. e.g. var sampleClass = Class.create({ initialize: function(){ //do the init work here }, functionA: function(){ //do some more stuff here } functionB: function(){ //Do some stuff functionA() } } I've tried calling functionA() , this.functionA() but nothing works I just get errors. I know how to call the functions externally when the class has been instantiated, but not reference a function from within the class itself. Thanks

  • How to increase Java heap space for a tomcat app

    - by Ankur
    There are lots of questions that ask this or a similar question. They all give the command that has to be executed, what I don't understand is where do I write this command. I want to permanently increase the heap space for my tomcat apps. I read this page http://javahowto.blogspot.com/2006/06/6-common-errors-in-setting-java-heap.html and it says under the Tomcat section Stop Tomcat server, set environment variable CATALINA_OPTS, and then restart Tomcat. Look at the file tomcat-install/bin/catalina.sh or catalina.bat for how this variable is used. For example, set CATALINA_OPTS=-Xms512m -Xmx512m (Windows, no "" around the value) export CATALINA_OPTS="-Xms512m -Xmx512m" (ksh/bash, "" around the value) setenv CATALINA_OPTS "-Xms512m -Xmx512m" (tcsh/csh, "" around the value) So I replaced the line set CATALINA_OPTS= with set CATALINA_OPTS=-Xms512m -Xmx512m But I still get the error.

  • Core dump utility for .NET

    - by Dave
    In my past life as a COBOL mainframe developer I made extensive use of a tool called Abendaid which, in the event of an exception, would give me a complete memory dump including a formatted list of every variable in memory as well as a complete stack trace of the program with the offending statement highlighted. This made pinpointing the cause of an error much simpler and saved a lot of step-through debugging and/or trace statements. Now I've made the transition to C# and .NET web development I find that the information provided by ASP.NET only tells half the story, giving me a stack trace, but not any of the variable or class information. This makes debugging more difficult as you then have to run the process again with the debugger to try and reproduce the error, not easy with intermittent errors or with assemblies that run under the likes of SQL Server or CRM. I've looked around quite a lot for something that does this but I can't find anything obvious. Does anyone have any idea if there is one, or if not, what I'd need to start with in order to write one?

  • Running Endpoint locally could not provide access to API explorer when HTTP proxy is enabled

    - by harik
    I'm using Android Studio(0.5.8) on Window7 x64 for developing my Android App with Google AppEngine backend. If my machine is having direct internet access and I launch backend locally (as DevApp Server) and access my API Endpoints through webbrowser (chrome) it is all working as expected. Accessing api explorer is also working fine from webbrowser. http://localhost:8080/_ah/api/explorer But if I have configured internet through http proxy (in Android Studio and also in webbrowser) then webbrowser displays initial page of backend but can't access endpoint api explorer. And deploying appbackend in Google AppEngine also fails with errors. gradlew backend:appengineUpdate Same is working fine if direct internet access is available (not via http proxy). How can we make it work with http proxy also? Any help is appreciated, Thanks.

  • using C function in C#

    - by andrew
    i have a dll, built with mingw one of the header files contains this: extern "C" { int get_mac_address(char * mac); //the function returns a mac address in the char * mac } I use this dll in another c++ app, built using Visual C++ (2008SP1), not managed, but plain c++ (simply include the header, and call the function) But now I have to use it in a C# application The problem is that i can't figure out how exactly (i'm new in .net programming) this is what i've tried public class Hwdinfo { [DllImport("mydll.dll")] public static extern void get_mac_address(string s); } When i call the function, nothing happens (the mydll.dll file is located in the bin folder of the c# app, and it gives me no errors or warnings whatsoever)

I also have the following function: void foo(boost::shared_ptr<const A> a) { boost::shared_ptr<const B> b = boost::dynamic_pointer_cast<const B>(a); // Error ! } Compilation with gcc gives me the following errors: C:\Boost\include/boost/smart_ptr/shared_ptr.hpp: In constructor 'boost::shared_ptr< <template-parameter-1-1> >::shared_ptr(const boost::shared_ptr<Y>&, boost::detail::dynamic_cast_tag) [with Y = const A, T = const B]': C:\Boost\include/boost/smart_ptr/shared_ptr.hpp:522: instantiated from 'boost::shared_ptr<X> boost::dynamic_pointer_cast(const boost::shared_ptr<U>&) [with T = const B, U = const A]' src\a.cpp:10: instantiated from here C:\Boost\include/boost/smart_ptr/shared_ptr.hpp:259: error: cannot dynamic_cast 'r->boost::shared_ptr<const A>::px' (of type 'const class A* const') to type 'const class B*' (source type is not polymorphic) What could possibly be wrong ?

  • ImageMagick and Grails not working

    - by TripWired
    I'm trying to have ImageMagick run from grails to convert some images when I run the command to make an image nothing happens. I get no errors, no information returned nothing at all. I've tried running other commands like touch and ps ux just to see if they work and they all work fine. It just seems like the imagemagick commands are getting lost and I''m not sure what to do. Here is the code I've been working with. String command = CH.config.ImageMagickPath + "/convert -size 40x20 xc:red xc:blue -append -rotate 90 append_rotate.gif" println command command.execute() CH.config.ImageMagickPath is set up to where imagemagick/bin is. I've taken what is shown in println command and run it in a terminal and it works fine. Is there any reason why I can't get IM to work from grails?

  • How to completely wipe rubygems along with rails etc

    - by Earlz
    Ok, so I decided I'd be cool and try to use Rails3 that's in beta. Then, things were getting hard to manage so I got rvm. I installed ruby 1.9.2-head in rvm and things were working, and then a computer restart later rails wouldn't start up. So I figured I'd just try running the system ruby and start rails in it. same error. Then, I uninstalled rails3 and got rails: no such file or directory type errors.. So now I'm royally screwed because rails2 is still installed but will not uninstall because of invisible dependencies, along with a lot of other random gems. How do I completely clear out all ruby gems and such so I can start anew?
