Oh nix my nix.

A heap of 0x11 different example 'Hello World' programs written in different languages along with very simple instructions on how to run them. Featuring: Python3, Ruby, Node.js, Lua5, C, C++, C#, D, Java, Shell, Brainfuck, Go, Rust, BBC Basic, Lisp, Fortran and x86-64 Assembly for Linux.

GNU is a recursive acronym for "GNU's Not Unix!", chosen because GNU's design is Unix-like, but differs from Unix by being free software and containing no Unix code. The GNU project includes an operating system kernel, GNU HURD, which was the original focus of the Free Software Foundation (FSF).

Kali Linux is a Debian-derived Linux distribution designed for digital forensics and penetration testing. It is maintained and funded by Offensive Security.

The null device discards all data written to it. This device is called /dev/null on Linux and Unix based systems and is also referred to as bit bucket or black hole in hacker jargon.

The Bourne Again Shell is a free software alternative of the original Bourne shell for Unix. It was written by GNU chad Brian Fox, and it's one of the first programs ported to Linux (thanks Linus!).

"I know this."

The Debian Project is an association of individuals who have made common cause to create a free operating system. This operating system is called Debian. Debian systems currently use the Linux kernel. Linux is a completely free piece of software started by Linus Torvalds and supported by thousands of programmers worldwide

Originally developed by IBM in the 1950s for scientific and engineering applications, FORTRAN came to dominate this area of programming early on and has been in continuous use for over half a century in computationally intensive areas such as numerical weather prediction, finite element analysis, computational fluid dynamics, computational physics, crystallography, and computational chemistry. It is a popular language for high-performance computing and is used for programs that benchmark and rank the world's fastest supercomputers.

A cool set of basic Linux commands including curl, alias, grep and of course, sudo.

Funny command (and so dangerous) for Linux users. Hope it bring to you a lot of laughs to make an awesome with Linux.

sudo boi! Sudo is a program for Unix-like computer operating systems that enables users to run programs with the security privileges of another user, by default the superuser. Often used by system administrators to force commands to run within a user profile that wouldn't ordinarily have the necessary elevated privileges and permissions to do so.

What people don't know, they can't ruin

Setting 777 permissions to a file or directory means that it will be readable, writable and executable by all users and may pose a huge security risk. For example, if you recursively change the permissions of all files and subdirectories under the /var/www directory to 777, any user on the system will be able to create, delete or modify files in that directory. If you experience permission issues with your web server, instead of recursively setting the permission to 777, change the file’s ownership to the user running the application and set the file’s permissions to 644 and directory’s permissions to 755. File ownership can be changed using the chown command and permissions with the chmod command.

Linux retro 70's style. Because that's when it really all began.

The best IDE. :)

Once root you can plant deeper roots and embed yourself, stay for a while, become established and hard to root out. This design sprung forth out of love of gaining root and planting things.
