Fuzz Testing Daala

A place where I can keep notes on fuzz testing daala. All tests here were done against commit sha d8daca8e9aadb1f6ba53e089b89824f170d59703 from Fri May 1, 2015.

16:50:05         radens | Do you guys run fuzz testers on daala? I was playing around with afl-fuzz
                        | today and was thinking of the recent android bug.
16:53:38      +TD-Linux | radens, no, and we should
16:54:03      +TD-Linux | tons of fuzzing was done on opus, though.

Contributing to Other People's Projects

Contributing to open source software is a difficult and rewarding process. Contrary to popular belief, it does not require a lot of programming skill, but rather patience, creativity, and diligence. In this post I will explain some crucial steps and skills which even experienced contributors sometimes forget. This is not a magic formula, and contributions will require focus and work, but in the end I believe the feeling that you are part of a community and that you have contributed to something greater than yourself is personally fulfilling.

	vagrant@debian-8-jessie-puppet:~$ puppet agent -t --server=192.168.33.10
	Info: Creating a new SSL key for debian-8-jessie-puppet.vagrantup.com
	Info: Caching certificate for debian-8-jessie-puppet.vagrantup.com
	Error: Could not request certificate: The certificate retrieved from the master does not match the agent's private key.
	Certificate fingerprint: 44:4D:D3:60:37:E1:1C:3A:91:0F:CB:DD:9B:3B:F8:3A:38:00:A4:3B:56:88:13:D4:E0:F5:77:E7:5F:FF:0D:CD
	To fix this, remove the certificate from both the master and the agent and then start a puppet run, which will automatically regenerate a certficate.
	On the master:
	puppet cert clean debian-8-jessie-puppet.vagrantup.com
	On the agent:
	1a. On most platforms: find /home/vagrant/.puppet/ssl -name debian-8-jessie-puppet.vagrantup.com.pem -delete

	How to use pip and virtualenv
	---------------------------------

	virtualenv is a program for managing python dependencies. If you have virtualenv installed you can manage use different versions of libraries and python with ease.
	Install virtualenv at the system level with one of these:
	```shell
	$ brew install pyenv-virtualenv #osx w/homebrew
	$ sudo pacman -S python2-virtualenv #arch linux
	$ sudo apt-get install python-virtualenv #ubuntu
	```

	#!/usr/bin/env python
	# -- coding: utf-8 --
