My main() starts with glewInit and glutInit Nope. You don't get a current GL context until glutCreateWindow() returns. You can call glewInit() and glewIsSupported() after that. Something like this: #include <GL/glew.h> #include <GL/glut.h> ... int main( int argc, char** argv ) { glutInit( &argc, argv ); glutInitDisplayMode( GLUT_RGBA | GLUT_DOUBLE ); glutInitWindowSize( 300, 300 ); glutCreateWindow( "OpenGL" ); glewInit(); ... return 0; }

You really need to run it with love.exe It is possible to build love as a shared library so you could, in principle, write an openlib wrapper over it. However, to get it to work in a reasonable fashion as a lua module would need a fair amount of work. I wouldn't want to put you off doing this if that's of interest to you but it's not really intended to work that way.

They mean you can develop under Windows and you do not have to compile the libraries for yourself. Binaries for GTK+ and its dependencies can be found here. Cross OS means that the same API is available across all supported platforms. Direct calls to the win32 API can be made normally in a GTK+ application.

According to the documentation of winexe: --interactive=0|1 Desktop interaction: 0 - disallow, 1 - allow. If you allow use also --system switch (Win > requirement). Vista do not support this option. So --interactive=1 --system should do the trick.

Sorry to bother all. I've found the resolution, just so simple. Simply change the BaseHTTPServer.HTTPServer's attribute allow_reuse_address to 0. The codes should be: from bottle import route, run, template import BaseHTTPServer @route('/hello/:name') def index(name='World'): return template('<b>Hello {{name}} </b>', name=name) setattr(BaseHTTPServer.HTTPServer,'allow_reuse_address',0) run(host='localhost', port=9999)

Try to call those by cmd.exe instead: cd UsersMeProjects start python Chord.py -i ini for /l %%a in (8001,1,8101) do ( ping /n 5 127.0>nul start cmd.exe /c python Chord.py -p %%a %%a ) echo. & pause

Thanks for answering, I finally installed Ubuntu 12.04 with windows7 on the same hard disk. As for my issue, virtualbox don't support full virtuallization, so I could not see any VMX feature in my Guest OS, but vmware do, which suits me well.

If you're on Linux you can use the /proc filesystem to check how commands communicate over pipes. However, this is not really portable.

Regarding second problem: str[a]*str[a-1]*str[a-2]*str[a-3]*str[a-4] = p; this assignment seems reversed. In addition str is a string made of characters '0' '1' '2' which are not directly numbers, or at least '0' != 0 since '0' is the character digit 0 which is encoded as 0x48

I found the answer using qmake --help. This actually says: Note: The created .pro file probably will need to be edited. For example add the QT variable to specify what modules are required. Adding these lines to the .pro file solved the problem: QT += core gui QT += widgets

You generally build such GTK programs using pkg-config. And I am getting (on Debian/Sid/AMD64) the compile flags % pkg-config --cflags gtk+-x11-3.0 -pthread -I/usr/include/gtk-3.0 -I/usr/include/atk-1.0 -I/usr/include/at-spi2-atk/2.0 -I/usr/include/pango-1.0 -I/usr/include/gio-unix-2.0/ -I/usr/include/cairo -I/usr/include/gdk-pixbuf-2.0 -I/usr/include/glib-2.0 -I/usr/lib/x86_64-linux-gnu/glib-2.0/include -I/usr/include/harfbuzz -I/usr/include/freetype2 -I/usr/include/pixman-1 -I/usr/include/libpng12 -I/usr/include/libdrm and the link flags % pkg-config --libs gtk+-x11-3.0 -lgtk-3 -lgdk-3 -latk-1.0 -lgio-2.0 -lpangocairo-1.0 -lgdk_pixbuf-2.0 -lcairo-gobject -lpango-1.0 -lcairo -lgobject-2.0 -lglib-2.0 Notice that these shared libraries link some

right click your project in eclipse "project explore" -> Run as -> Run configuration =>select your project name then check "Main" tab, in C/C++ application file. is it point to your binary file? E.g: Debug/TestProj.exe

If process can run separately one after another You can try put "in-steps", /** step 1*/ $process1 = proc_open($command_exe1, $descriptorspec1, $pipes1, $cwd) ... while(!feof($pipes1[1])) { $StdOut1 = stream_get_contents($pipes1[1]); } echo $StdOut1; /** step 2*/ $process2 = proc_open($command_exe2 $descriptorspec2, $pipes2, $cwd) while(!feof($pipes2[1])) { ...

I'm not familiar with frege, and I haven't tried to use scala or other JVM languages on Android. That being said, if I were to try something like that, these are the steps I would likely take to try and figure out how to get it to work. Build a simple command line based HelloWorld type application in frege, that can be run with, e.g. java -jar HelloWorld.jar HelloWorld Run dx on HelloWorld.jar, and then try to get the example working on an android device from adb shell, using dalvikvm. i.e. dalvikvm -cp blah.dex HelloWorld Figure out how to reference/use classes from the android.jar provided by the Android sdk in frege Build a simple proof of concept Activity class in frege, and manually build a classes.dex file from it Build a similar proof of concept application in java and use the

The culprit is User Account Control (UAC). UAC doesn't allow white listing a particular application. You have to disable it to get rid of these messages. To know more about UAC or to diable it see http://www.petri.co.il/disable-uac-in-windows-7.htm

You should look int Boost Threads. There are examples on the web on how to create a program and use Boost Threads to call either a class method or a non-class static method. About using C++ library in C code, this stackoverflow post may be helpful. I guess using extern scope operator is the magic here. C++ cross-compiler is designed using C, so backward conversion is not impossible. If you hit success in using C++ into C Wikipedia listed these for Multithreading libraries for C++. I guess it is worth visiting those and see what is good. Boost is still the best IMPO. P.S. You should checkout intel's Threading Building Block TBB too. They are quite good and simple. Open source projects such as OpenCV uses tbb for their multithreaded class ops. the link is here

I found an indirect way to do it - via cmd. That's not the best way, but it may work. You can write the following text in the resources as name.cmd: 'sets the name of your app to display reg add "HKLMSoftwareMicrosoftWindowsCurrentVersionUninstallYourapp" /v "DisplayName" /d "Yourapp" /f 'sets your app version to display REG ADD "HKLMSoftwareMicrosoftWindowsCurrentVersionUninstallYourapp" /V "DisplayVersion" /D "1.0.0.0" 'sets your app icon to display location REG ADD "HKLMSoftwareMicrosoftWindowsCurrentVersionUninstallYourapp" /V "DisplayIcon" /D "%PROGRAMFILES%Yourappyourapp.ico" 'sets your name to display as publisher REG ADD "HKLMSoftwareMicrosoftWindowsCurrentVersionUninstallYourapp" /V "Publisher" /D "Yourname" 'sets the uninstall path REG ADD "HKLMSoftwareMicrosoftWindowsCurrentV

My question is this: Is it possible to preserve pseudorandomity without having inter-thread communication and if so, how? Yes it is. Make each thread use a separate random number generator (with a different but deterministic seed).

What your code does is wrong; you're trying to share a variable between two processes but what you've done is sharing between two source files so declaring a variable as an extern certainly doesn't help you; because that's what you do if in one process you want to expose a variable in one source file to other source files. A natural way to share a variable between two(or more) processes(programs) is something in UNIX systems called shared-memory. Please check this link for an introduction. http://www.cs.cf.ac.uk/Dave/C/node27.html Edit: Of course, inter-process communication(how two processes talk with each other) isn't limited to shared memory, you can also share a variable by sockets or through pipes

Do not use such components. This is dangerous no matter what creator says. I'm Joomla extension developer and believe me it can ruin your application and make more problems and benefits. Depends on what you want to archive and how big will be your project you have few possibilities: 1. Create component that will execute commands Something similar to what U did but based on custom created component. Its fastest and cheapest way. Problem starts when your Java application will use more resources then website (interface). So its more like good solution for start. 2. Create component that will contact application written in Java via API This is good solution if your Java application use a lot of resources. You can run it on several servers, manage servers load so clients gets results faster

The first program prints the value of the uninitialized pointer p interpreted as an unsigned integer. Since the pointer is not initialized the value printed is whatever value happens to be in that location. The second program prints the address of the pointer p interpreted as an unsigned integer. While not technically legal, it will work on most systems where the sizeof(char *) == sizeof(unsigned int). Since the variable "p" is an automatic variable you will get a value in the address range that your runtime assigns to the C stack. Edit: to clarify from the comments. Printf formats the data passed to it in parameters according to the control string. %u means to print an unsigned integer. So when you pass in p, C passes in the value of the pointer variable to printf. The # of

You're generating the random number outside of your loop. Therefore it will exist as the same number every time. The solution is to move the definition inside of the loop. public static void main(String[] args) { for(int counter = 0; counter < 30; counter++){ int random = (int) (Math.random() *50) +25; System.out.println(random); } } In this way, every time through the loop (30 iterations), your code will (1) generate some random number and (2) print that number.

The easiest solution is to put the server and client in the same Eclipse project: Both Server and Client can have a main() and be in the same project. Create two separate run configurations in eclipse (one for Server, one for Client) -- note that run configurations are created automatically if they don't exist when you press the "play" button in eclipse (just make sure the file that has the main() method is open in the editor when you press play), so you probably won't need to do this manually. Then, in eclipse, when you export the program, export it as a Runnable JAR (if "Runnable JAR" isn't available in the export quick menu just select "Other..." and search for it). You can select the run configuration. So export one for client (maybe name it client.jar) and one for the server (maybe

I've tried this query with the data that you provided (I had to add the prefixes): prefix wo: <http://purl.org/ontology/wo/> prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> select ?individual ?type ?label where { ?individual rdf:type ?type . ?individual rdfs:label ?label filter (?type in (wo:Kingdom)) } I ran the query using Jena's command line arq with the following results: $ arq --query query.sparql --data ontology.owl ------------------------------------------------------------------- | individual | type | label | =================================================================== | <file:/nature/life/Animal#kingdom> | wo:Kingdom | "Animals" | |

You have to import class Hello: import Hello class HelloController { def index() { Hello.main(null) } } See Java docs about packages and import statement: http://docs.oracle.com/javase/tutorial/java/package/usepkgs.html

You should be concerned. I assume you are sure that no other program (than the two executables mentioned in your question) are accessing that file. You should indeed lock to serialize that access. Use flock(2), or lockf(3) which uses fcntl(2) BTW, is the file read and written sequentially? Did you consider using some higher-level thing, e.g. GDBM or some database like mariadb or postgresql or mongodb, etc...

The typical process for this type of thing is to use a full-screen shader in post processing using the depth buffer from your fully rendered scene, or using a z-pass, which renders only to the depth buffer. You can chain them together and create any number of effects. It typically involves some render-to-texture work, and is not a real trivial task (too much to post code here), but it's not THAT difficult either. If you want to take a look at a decent post-processing system, take a look at the PostFx system in Torque3D: https://github.com/GarageGames/Torque3D And here is an example of creating fog with GLSL in post: http://isnippets.blogspot.com/2010/10/real-time-fog-using-post-processing-in.html

Well... There's always multithreading: Stack Overflow, for example. But it's always a complicated process, especially for C++. I'm afraid you'll have to google some tutorials for your particular case. Here are some: tutorialspoint, codebase, plenty more around. There are a lot of methods, achieved by many distinct libraries, and none of them could be considered simple.

I'll tell you the correct answer and you're probably not going to like it. Without knowing all the specifics of your code, it sounds like you need to do some heavy refactoring. In an ideal world, when you write your application, it should be written in such a way that the implementation is done as a formal API and the main() translates/parses the command-line arguments into appropriate calls into the API. If done correctly, the file that has the main() routine is only needed to build the executable for its task. Better still, the implementation would be built as a library and a set of headers for using that library. Then your task would not be blenderizing two executables, but instead building a new application that calls two different libraries. The reason that you're not going to li

Just as every C application and C++ application must have a main function as its starting point, every Win32-based application must have a WinMain function. Take a look: http://msdn.microsoft.com/en-us/library/vstudio/bb384843.aspx

To be clear, I believe you have an app written in Java that uses Libgdx currently, and you would like to extend that app by including a C library and making calls out to the C library from the Java application. Libgdx does not provide any special support for third-party libraries, native or Java. You will have to use the backend platform's APIs to call out to native code (JNI, NDK, etc). You should be able to add your library to the Android and Desktop backend projects, and access it via a Platform Interface. It is probably not possible to use the GWT-backend (unless you have a C to Javascript compiler). For iOS you would need to build your library for iOS, and then figure out how to link it into the Xamarin (or robovm) build process for your app. While I'm going to assume this is po

Please see this example in Codeproject. it's a sample documentation of Windows Audio Mixer API Wrapper Library Hope will help it.

The documentation says this, have you set these Attributes (DisableModify & DisableRemove) in your bundle? If the "DisableModify" attribute is also "yes" or "button" then the bundle will not be displayed in Progams and Features and another mechanism (such as registering as a related bundle addon) must be used to ensure the bundle can be removed. DisableRemove YesNoType Determines whether the bundle can be removed via the Programs and Features (also known as Add/Remove Programs). If the value is "yes" then the "Uninstall" button will not be displayed. The default is "no" which ensures there is an "Uninstall" button to remove the bundle. If the "DisableModify" attribute is also "yes" or "button" then the bundle will not be displayed in Progams and Features and another me

You have to tell whether the visitor is human or bot in the first place. This no easy task, see e. g. : Tell bots apart from human visitors for stats? Then, if you detected what bot it is, you can decide wether you want to give it your website content or not. Legitimate bots (like Googlebot) will conveniently provide their own userAgent id; malicious bots / web crawlers may disguise themselves as common browser programs. There is no 100% solution, anyway. If you content is really sensitive, you may want to add captcha, or user authentication.

Pankaj, you can always visit the official page.

Any of the last 3 versions of eclipse work perfectly fine. Don't know about earlier versions. You can either run your job through Eclipse directly or you can write your job in Eclipse and export it as a jar. You can then copy this jar to your JT machine and execute it there through the shell using hadoop/jar command. If you are running your job directly through the eclipse you need to tell it the location of your

Using netstat -an you will see which ports that are in a connection at the moment. If you want to see which process that is connected to a certain, port 80 in this case, you can use lsof -i tcp:80 Well, you need to be root, of course.

That design makes no sense whatsoever, and the claim that it's better not to use threads or child processes makes even less sense. You have three sources of requests: Request Source A: Make web request to a server every 5 seconds. Request Source B: Make database request to a server every 60 seconds. Request Source C: Accept requests from a socket. Create a thread for each Request Source. Their job is solely to monitor each Request Source in order to ensure that the Sources are checked when they should be checked. As such, none of these threads should do any real work. If a task must be performed, they delegate the work to a worker thread. They don't POST anything. They don't write to the database. The actual tasks (including sending POSTs and writing to the database) are performed by

echo $PATH | tr ":" " " | while read line; do echo $line; ls $line; done Be prepared for tons of output. You might be better off doing echo $PATH first and looking for interesting-looking directories, or just seeing if tab-completion works (just type 'c', tab, see if it shows 'cat', 'cd', etc). Really tho, ask the prof for whatever docs you're supposed to have, the tools you're looking for aren't likely to be obvious just from the name of the command.

The syntax highlighting you are seeing is a compile error. The termination checker's effect is to highlight non-terminating functions in a kind of pink-orange color ("salmon"). You may notice that a module containing such an error cannot be imported from other modules. It can also not be compiled down to Haskell. So yes, Agda programs always terminate and this is not a bug.

You can do this with a named pipe: mkfifo xy_pipe ./program_x < xy_pipe | ./program_y > xy_pipe A regular pipe is used to connect x's stdout to y's stdin. To connect y's stdout to x's stdin we create a second, named pipe using mkfifo. A named pipe is an explicit way to connect two processes the way | normally does. Whenever a process writes to a named pipe it blocks until another process reads from the pipe. Although xy_pipe appears to be a file, no data is actually written to disk. Example: $ cat program_x #!/bin/bash echo foo read line && echo "program_x: read '$line'" >&2 $ cat program_y #!/bin/bash read line && echo "program_y: read '$line'" >&2 echo bar $ mkfifo xy_pipe $ ./program_x < xy_pipe | ./program_y > xy_pipe program_y: read 'f
