  3. thou shalt not take the name of python or scikit-learn in vain
  4. keep holy the juypter notebook
  5. honour thy pip and thy modules
  6. thou shalt not ^C any running ...

We’re starting off the new year with two new ways to listen to the Data-Driven Security Podcast!

First, we have our own Overcast station fully loaded with the previous two seasons of shows. You can listen to them online right on or use their minimalist but highly ...

There is a lot of misperception around sample sizes and the confusion happens on both sides of the research. A common question when researchers are starting out is, “How big should my sample size be?.” To help with that, there are handy calculators all over the Internet. But the more ...

We have some strange data in cybersecurity. One of the (IMO) stranger data files is a Domain Name System (DNS) zone file. This file contains mappings between domain names and IP addresses (and other things) represented by “resource records”.

Here’s an example for the dummy/example domain ...

This was (initially) going to be a blog post announcing the new mhn R package (more on what that is in a bit) but somewhere along the way we ended up taking a left turn at Albuquerque (as we often do here at ddsec hq) and had an adventure in ...

UPDATE: RBerkeley is now on CRAN

If you made it to Chapter 8 of Data-Driven Security after ~October 2014 and tried to run the BerkeleyDB R example, you were greeted with:

Warning in install.packages :
  package ‘RBerkely’ is not available (for R version [YOUR_R_VERSION])

That’s due to the fact ...

The R world has come a long way since Jay & I wrote Data-Driven Security. We had to make a conscious decision to stick with R 2.14.0 (R is at version 3.2.1 now) and packages such as knitr and dplyr either didn’t exist or were in ...
