    Perfect Spatial Hashing (Lefebvre & Hoppe)

    how it works:

    There are two parts: a slow encoding step, and a fast decoding step.

    Encoding

// Despite appearances to the contrary, this does proper error handling. Any error cascades into a failure of the wglGetProcAddress.
int init_opengl() {
    HWND window = CreateWindowA("edit", "", WS_OVERLAPPEDWINDOW, 0, 0, 0, 0, NULL, NULL, NULL, NULL);

    PIXELFORMATDESCRIPTOR format_desc = {
        .nSize = sizeof(PIXELFORMATDESCRIPTOR),
        .nVersion = 1,
        .dwFlags = PFD_DRAW_TO_WINDOW | PFD_SUPPORT_OPENGL
    };

What is Vulkan

Vulkan is a low-overhead, cross-platform 3D graphics and compute API.

Vulkan targets

Vulkan targets high-performance realtime 3D graphics applications such as games and interactive media across multiple platforms providing higher performance and lower CPU usage.

#Compilng You need g++ 4.9 to compile this code. Follow these steps to install g++-4.9

After installing run the following command to compile

/usr/bin/g++-4.9 -std=c++11 lambda.cpp

#Running

./a.out

PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

• -E: will describe the underlaying queries of the \ commands (cool for learning!)
• -l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)
