The glGenBuffers and related functions are nowhere to be found on the default installation of the OpenGL SDK. It’s not THAT painful to get it done (if you know where to look).

First, you’ll need glext.h that you download from the OpenGL website, then you’ll need to declare and reference the functions at runtime. Something like this:

#include "glext.h"
PFNGLDELETEBUFFERSPROC glDeleteBuffers;
PFNGLGENBUFFERSPROC glGenBuffers;
PFNGLBINDBUFFERPROC glBindBuffer;
PFNGLBUFFERDATAPROC glBufferData;
PFNGLBUFFERSUBDATAPROC glBufferSubData;
PFNGLMAPBUFFERPROC glMapBuffer;
PFNGLUNMAPBUFFERPROC glUnmapBuffer;
void initGLFunctions() {
  glGenBuffers = (PFNGLGENBUFFERSPROC) wglGetProcAddress(LPCSTR("glGenBuffers"));
  glDeleteBuffers = (PFNGLDELETEBUFFERSPROC) wglGetProcAddress(LPCSTR("glDeleteBuffers"));
  glBindBuffer = (PFNGLBINDBUFFERPROC) wglGetProcAddress(LPCSTR("glBindBuffer"));
  glBufferData = (PFNGLBUFFERDATAPROC) wglGetProcAddress(LPCSTR("glBufferData"));
  glBufferSubData = (PFNGLBUFFERSUBDATAPROC) wglGetProcAddress(LPCSTR("glBufferSubData"));
  glMapBuffer = (PFNGLMAPBUFFERPROC) wglGetProcAddress(LPCSTR("glMapBuffer"));
  glUnmapBuffer = (PFNGLUNMAPBUFFERPROC) wglGetProcAddress(LPCSTR("glUnmapBuffer"));
  if (glGenBuffers == NULL) {
    const char *version;
    fprintf(stderr, "Cannot properly initialize extension functions!\n");
    version = (const char*)glGetString(GL_VERSION);
    fprintf(stderr, "OpenGL version:%s\n", version);
  }
}

The above code provides you everything you need to use the VBO related functions, but there are many many functions declared inside glext.h. You could create prototypes like above for any of them.

Beware the version of your graphics card driver. Microsoft default driver usually comes with support to OpenGL 1.1 version only, wich is not good enough for VBO.

App Store Link

The Eve Online App was submitted to the AppStore and it’s waiting for approval, but i’m providing you all some screenshots so you can take a sneak-peek.

The App provides Local Notifications of completion skills. You don’t need any internet connection to receive the notifications, only to update your API information.

v. 1.0 (released)

v. 1.1 (waiting for approval)

Changelog:

v. 1.2 (in development)

coming soon…

It assumes that you already know how to code, and is moving to a new platform (in this case Cocoa). It helped me a lot (and it still does) when I came from my C/C++ background to the MacOS Cocoa + ObjectiveC. It’s a hands-on approach that leaves no gaps in the explanations.  I’ve found myself many times coming from the Apple’s official tutorials to the eBook to get some clarification on some topics. It’s great both for learning and for reference.

If you’re new to programming and is starting in a MacOS platform, you can check out the Beginning Mac Programming: Develop with Objective-C and Cocoa. I haven’t read this one, but it seems to make the same approach from the first one, except it does not assume any programming background.

In the meantime, my wishlist is available with some other options of books (and, if you want to send me a gift, those are great ones).

Searching the web, I’ve found many language functions to convert lines, strings or chunk of bytes from one encoding to the other, but I have in my hand a plain-text file (a rather large one).

I’ve used the Unicode Mapping CodePage 936 available from the unicode page to do the trick. Not all characters are there, but it mostly works. Since I’m quite in a hurry, this one will do for now. I’ll later try to encode it with BestFit 936 to see what I get (note: The current code does not work out-of-the-box with the BestFit file format. Some tweaking is needed).

So, having in hands the codepage, I figured I could make a small python script to convert my file to another encoding (UTF-8, in this case) and I’m sharing it with everyone (GPL License).

If this code is useful for you, you could donate (any amount) to show your appreciation from the link below.

It was coded on a Mac, using Python 3.1, but it also works on Windows (I’ve tested it on a XP). Note that it’s quite crude and you need to alter some settings at the beggining of the file (Source file and Destination file at least).

You can choose to work online or offline. When online, the program fetches the conversion rate from the internet and used for your conversions.

Feedbacks and suggestions are welcome! Also, you like the software and want to show your appreciation, please, donate using the link below!

Download for MacOSX 10.6:

Here are some screenshots:

An simple online currency converter application made for MacOS 10. This simple application lets you choose an target and destination currency from a predefined list and it convert the currencies for you.
It fetches online the current convertion rate, displays it to you and the target value.

It is very simple and plain. No in-depth work. Just saves you the time to go online, search the site and do the math by yourself.

I’ll post a download link later this week.
