Effective Modern CMake

Getting Started

For a brief user-level introduction to CMake, watch C++ Weekly, Episode 78, Intro to CMake by Jason Turner. LLVM’s CMake Primer provides a good high-level introduction to the CMake syntax. Go read it now.

After that, watch Mathieu Ropert’s CppCon 2017 talk Using Modern CMake Patterns to Enforce a Good Modular Design (slides). It provides a thorough explanation of what modern CMake is and why it is so much better than “old school” CMake. The modular design ideas in this talk are based on the book [Large-Scale C++ Software Design](https://www.amazon.de/Large-Scale-Soft

# Put in your ~/.ssh/config

### Problem
#
# You are on a public WiFi network that blocks SSH ports but you don't want to switch 
# to pushing your Github changes to GH remotes via HTTPS nor do you want to change the
# remote hostname in all your repos.

Host github.com
  Hostname ssh.github.com

How to grow a partition in Linux

This guide will walk you through the steps required to grow a partition in Linux. You will have to reboot through this guide.

1. If possible, make a snapshot.

Often, you will want to grow the partition table because you made your virtual hard disk too small, and you tried to extend it in your hypervisor, only to find out that your partition is still the same size as it was before.

## Redis Lua 5.1 sandbox escape 32-bit Linux exploit
## Original exploit by corsix and sghctoma
## Author: @c3c

## It's possible to abuse the Lua 5.1 sandbox to obtain RCE by loading modified bytecode
## This concept is fully explained on corsix' gist at https://gist.github.com/corsix/6575486
## This version uses pieces of the 32-bit Windows exploit made by corsix and the 64-bit Linux exploit made by sghctoma; as expected, a few offsets were different
## sghctoma's exploit uses the arbitrary memory read to leak pointers to libc and find the address of "system" http://paper.seebug.org/papers/Security%20Conf/Defcon/2015/DEFCON-23-Tamas-Szakaly-Shall-We-Play-A-Game.pdf
## This code is much the same, except the process is done using pwntools' DynELF
## Furthermore, attempting to leak addresses in libc appears to cause segfaults on my 32-bit Linux, in which case, you will need to obtain the remote libc version
