Buffer Overflow Tutorial

This tutorial is based on the Computerphile video, made by Dr. Mike Pound

https://www.youtube.com/watch?v=1S0aBV-Waeo

The tutorial will show you how to trigger and exploit a buffer overflow attack against a custom C program, using Kali Linux 32-bit PAE 2016.1.

Example: Moving up to a few commits to another branch

Branch A has commits (X,Y) that also need to be in Branch B. The cherry-pick operations should be done in the same chronological order that the commits appear in Branch A.

cherry-pick does support a range of commits, but if you have merge commits in that range, it gets really complicated

git checkout branch-B
git cherry-pick X
git cherry-pick Y

Crawling Anonymously with Tor in Python

adapted from the article "Crawling anonymously with Tor in Python" by S. Acharya, Nov 2, 2013.

The most common use-case is to be able to hide one's identity using TOR or being able to change identities programmatically, for example when you are crawling a website like Google and you don’t want to be rate-limited or blocked via IP address.

Tor

Install Tor.

The fastest remote directory rsync over ssh archival I can muster (40MB/s over 1gb NICs)

This creates an archive that does the following:

rsync (Everyone seems to like -z, but it is much slower for me)

a: archive mode - rescursive, preserves owner, preserves permissions, preserves modification times, preserves group, copies symlinks as symlinks, preserves device files.
H: preserves hard-links
A: preserves ACLs
