This guide is for homelab admins who understand IPv4s well but find setting up IPv6 hard or annoying because things work differently. In some ways, managing an IPv6 network can be simpler than IPv4, one just needs to learn some new concepts and discard some old ones.
Let’s begin.
First of all, there are some concepts that one must unlearn from ipv4:
Concept 1
#!/usr/bin/sudo ruby | |
# | |
# revealer.rb -- Deobfuscate GHE .rb files. | |
# | |
# This is simple: | |
# Every obfuscated file in the GHE VM contains the following code: | |
# | |
# > require "ruby_concealer.so" | |
# > __ruby_concealer__ "..." |
This simple script will take a picture of a whiteboard and use parts of the ImageMagick library with sane defaults to clean it up tremendously.
The script is here:
#!/bin/bash
convert "$1" -morphology Convolve DoG:15,100,0 -negate -normalize -blur 0x1 -channel RBG -level 60%,91%,0.1 "$2"
Use folowing steps to repackage dep package: | |
1: Extract deb package | |
# dpkg-deb -x <package.deb> <dir> | |
2: Extract control-information from a package | |
# dpkg-deb -e <package.deb> <dir/DEBIAN> | |
3. After completed to make changes to the package, repack the deb | |
# dpkg-deb -b <dir> <new-package.deb> |
IMPORTANT! |

As of May 17, 2020, python-vipaccess stopped working for provisioning new Symantec VIP Access tokens (which was its raison d'être). |
As of May 27, 2020, it's working again. |
It might stop working again. and we might not be able to get it to work again (see #39) |
Note: Your password cannot be more than 26 characters for you to use 2FA in general. eTrade makes you enter your 2FA code appened to your password to login and limits the length of password input to 32 characters, thus further restricting the maximum length of your actual password.

Why do compilers even bother with exploiting undefinedness signed overflow? And what are those | |
mysterious cases where it helps? | |
A lot of people (myself included) are against transforms that aggressively exploit undefined behavior, but | |
I think it's useful to know what compiler writers are accomplishing by this. | |
TL;DR: C doesn't work very well if int!=register width, but (for backwards compat) int is 32-bit on all | |
major 64-bit targets, and this causes quite hairy problems for code generation and optimization in some | |
fairly common cases. The signed overflow UB exploitation is an attempt to work around this. |
