# File:         nim_opengl_shader_example.nim
# Author:       Benjamin N. Summerton <define-private-public>
# Description:  An example of how to use OpenGL shaders in Nim.  Draws a simple
#               rotating hexagon with 6 colors.  Also uses indexed drawing.
#
# Uses this GLFW binding: https://github.com/rafaelvasco/nimrod-glfw, though if
# want to use SDL2, changing out the windowing should be simple.
#
# This was built on Linux using OpenGL ES 3.  If you want to use a different
# OpenGL version then you will have to alter the shader source.

Don't use VPN services.

No, seriously, don't. You're probably reading this because you've asked what VPN service to use, and this is the answer.

Note: The content in this post does not apply to using VPN for their intended purpose; that is, as a virtual private (internal) network. It only applies to using it as a glorified proxy, which is what every third-party "VPN provider" does.

• There's also this article about VPN services, which is honestly better written (and has more cat pictures!) than my article.

In reply to "@Vlad_Roberto: No, not a programmer. I just know there's better ways to doing anything without massive energy consumption & Banks."

The problem of blockchain synchronization is the following:

Imagine you are sitting in a bunker. You have no idea what people are out there and what are their intentions. You only receive some incoming messages from strangers that may contain anything. They can be just random garbage or deliberately crafted messages to confuse you or lie to you. You never know. You cannot trust anyone.e

The problem of "money" or any other "social contract" is that everyone should be able to know what the majority agrees to without trusting some intermediaries (otherwise they can easily obuse their special position). If everyone votes for "X", then you sitting in a bunker must somehow independently figure out that all those other people indeed voted for "X" and not for "Y" or "Z". But remember: you cannot trust anyone's message and messages are the only thing you get from the outsi
