Things I Learned From DEFCON

Pentoo - Linux distro for pen testing.
VMware fusion - Most of the presenters were using a Macbook with VMware fusion managing their VMs.
Chinavasion - One of the presentations mentioned this in the context of dealextreme, I'm assuming this site is similar.
Kali linux - Another distro for pen testing.
Open bts
Sqlmap (SQLi injection) - Python tool used to tell if php pages were vulnerable to SQLi injection.
C99 shell - PHP interface for shell level system functions.
b374k shell - Another shell which allows an user to run file system, database, and shell commands from a web interface.
Accunetix (xss)
Business logic flaws in mobile operators
Doskey /history - Will show you all the previous commands typed into command prompt.
Maria DB - When oracle took over MySQL, it forked and maria db is still run by the previous developers.
Firefox imacro - A presenter said he uses this for all of his bots.
Burp repeater - Looks similar to fiddler, allows repeating http packets. Maybe only for Mac.
Fritzing
Groupie and Geocouch (couch dB) - This was used in combination with the unity engine to display clusters of map points in a video game.
Steganography - The word for hiding data inside of other files. A presenter showed how histograms could be used.
Femtocells - A personal cell tower. One of the presentations talked about how to use a femtocell to intercept text messages to a Verizon (CDMA) phone.
Shark - Has something to do with a hadoop, good for storing large amounts of data.

This is happening because you're on an unsupported/old version of Ubuntu.

One way to fix it:
  1. nano /etc/apt/sources.list
  2. Change all entries referring to http://archive.ubuntu.com/ubuntu to http://old-releases.ubuntu.com/ubuntu

Change Percent To Numbers and Keep Color - Flot Pie Chart

You can access the color of the section of the pie chart by using “series.color”:

Overwriting module with same version in Heroku - Python

I needed to install a newer version of a module from a github commit, but it had the same version number. Heroku just used the cached version of the module and didn't overwrite it with the newer version.

The easiest fix for this:

  1. Create a file in your application's root directory called "runtime.txt" with only "python-3.4.1" written inside.
  2. Add, commit, and push the new runtime.txt
  3. Change runtime.txt back to "python-2.7.6"
  4. Add, commit, and push to clear your virtualenv and reinstall all modules
