Automated solver for 2048

This is a script which runs a "bot" that tries to solve the incredibly addictive 2048 game. It makes use of Groovy and browser automation with Geb.

How to

• First step, if you don’t have it, you need to install Groovy.

• Second step is to install the Google Chrome WebDriver (just unzip the appropriate file to a local directory)

• Next, edit the script to set the path to the Chrome Driver

• then execute the script: groovy solver2048.groovy

(* How do to topology in Coq if you are secretly an HOL fan.
   We will not use type classes or canonical structures because they
   count as "advanced" technology. But we will use notations.
 *)

(* We think of subsets as propositional functions.
   Thus, if [A] is a type [x : A] and [U] is a subset of [A],
   [U x] means "[x] is an element of [U]".
*)
Definition P (A : Type) := A -> Prop.

Linux - Nvidia switchable setup guide

The aim of this guide is to provide a working strategy to make your dedicated graphic card turn on/off correctly in a Linux environment (with xorg).

The following scripts have been created by tyrells and this guide is a remake of Graff's one.

Required Packages

The following two packages are stricly required:

nicebyte

#pragma once

#define DYN_ARR_OF(type) struct  { \
  type *data; \
  type *endptr; \
  uint32_t capacity; \
}

#if !defined(__cplusplus)
#define decltype(x) void*
