RainbruRPG is an open-source MMORPG project I'm working on since someday in early 2010's. I already posted multiple posts on this project (for example here and here ). While its development is actually in pause for a while now, it is a great project to learn using new 3D/UI oriented libraries. CEGUI (short for Crazy Eddie's GUI System ) is one of these libraries. It is a free MIT-licensed windowing and widgets library that run on top of Ogre3D but it can also run on other backends. The RainbruRPG's not yet implemented modal dialog The modal need While CEGUI is a great library to create windows and complex screen, I need a standard dialog for NYI (Not Yet Implemented) features. For this, I'll try to create a modal dialog, i.e. a dialog with a blocking exec() function and a return value. It can have multiple buttons, each possibly with a different value but the blocking execution is needed : ModalDialog md; if (md.exec()) { // handle positive eve...

This issue comes from some research for RainbruRPG while working with openssl function (see NewProfile class). This C function is waiting for a void* parameter as passphrase, and I'm getting the user-entered password as a std::string .   The problem is, if you try to pass it directly, use get the following error : error: cannot convert 'std::string' {aka 'std::__cxx11::basic_string '} to 'void*' To pass it to the legacy void* function, you just need to pass a pointer to the first element of the string : #include <string> #include <iostream> void waiting_for(void* str) { using std::cout; using std::endl; // You have to cast it or you'll print the pointer // address instead of the string content cout << (char*)str << endl; } std::string passphrase = "whatever"; waiting_for(&passphrase[0]); This trick also works with char* but you have to cast the result (at least on g++ ) to av...

The mrt-manager homepage When trying to run mrt-manager , a  meteorjs project, on a newly installed Debian Stretch , I had the following issue : Unexpected mongo exit code 1. Restarting. Unexpected mongo exit code 1. Restarting. Unexpected mongo exit code 1. Restarting. Unexpected mongo exit code 1. Restarting. Unexpected mongo exit code 1. Restarting. Can't start Mongo server. MongoDB failed global initialization I got this issue when trying to work on mrt-manager after a fresh Debian install. This issue is due to a missing locale , a set of language/country code pair used to define user interface language in i18n context. You probably installed your favorite GNU/Linux distribution in your native language and you didn't installed the english locale. Edit the /etc/locale.gen as root and uncomment the following line : en_US.UTF-8 UTF-8 Then execute the following command as root : #locale-gen Now, reboot the computer and mongodb should start.

I'm not dead yet and neither is my code. This blog, however is, and I will try to fix that.   Actual state The truth is that, these days, I was more into streaming and competitive programming than traditionnal, more serious development. I splitted my dev repos in two different accounts, bitbucket for all professional-related and old work and a « new » gitlab account, used for game-related ans streamed repositories. While my old dev name remains *rainbru*, my new streamer name is now discontinued. The new repositories will created at github with a big focus on company/industry-related project, mainly written in C++,ruby,perl and JS. This will give daily commit if I can, side by side with an active work on freecodecamp and mit's ocw daily work tyo heavently have some certifications. Reactivation So, I'll try to reactivate this blog, trying to post some dev-related articles more than once in a five years span. Btw, today is also my birthday -- yippee!
