I taught my first class back in 2009. I have taught many classes since. I think something I quickly learned was everybody had a better experience when I was enjoying myself. So I did things that made the class more fun for me. Things like explaining cryptography through Shakespeare, use case diagrams via method of…
As part of our efforts surrounding the Danish Cybersecurity Championship, we are offering a course on Bash scripting. While we used Haaukins platform for some activities, one can carry out the exercises on any Linux machine (maybe a bit less easily). As part of the course, I created content that includes videos, tutorial documents, exercises…
As part of an Industriens Fond initiative, we have been developing cybersecurity adjacent courses for the general Danish public. One of the courses we developed is personal privacy for the youth. The course is designed for high school students, and freshmen. The topics we cover are: Stalking and Cyberbullying Corporate Tracking and Add Supported Business…
Learning to record lecture videos using open source tools.
The teaching evaluations for my last semester here in OU just came in. Wait… I have something in my eye. What?!? NO! I’m not crying! You’re crying! I can’t describe how satisfying getting a review like this was, especially for a course as though as MIS2800. I had some good evaluations in the past, but…
I was slated to teach Predictive Analytics 2 as part of the analytics masters degree here in OU. I have been developing the course content slowly the past few months. Now, with the move to Denmark coming up this summer, I will not get to use this content in the class room. I figured I…
A few months ago I made a presentation on Tensor Flow for MBA students. The challenge was to simplify the technical underpinnings of the technology sufficiently while preserving a semblance of what it was good for. One particular challenge was visualizing the technology. Showing python code and output was out of the question and at…
Google open sourced TensorFlow (TF), a distributed machine learning library, in November. The basic idea is that, you build your ML process into a graph and let TF handle the running and distribution of the work between cores. Be it cores in your CPU or GPU, TF has you covered. The dataflow graph works much…
I am currently developing a tutorial for EMBA students for IBM’s Watson Explorer. Having just recently finished content development for R workshop for MSBA, I must say it is a pretty interesting experience. On the one hand you have R, a complex but powerful tool that is designed to lift (almost) any kind of analytics…
I have been working on the upcoming R workshop for a few weeks now. Finally I am ready to publish part of the material in the spirit of open source, so that others can benefit from, and improve upon my material. I uploaded all the materials to my github repository. There are a few documents…
I am preparing presentations for the upcoming R workshop. That means I have to find a way to integrate R code and results into my presentations. Now I know there are a number of ways to achieve this, but I like beamer for presentations and R for analysis. Now thanks to Knitr, I can bring…
I am working on a workshop for Business Analytics masters students. Part of the demos I intend to use are geographical visualizations. I am using rworldmap package to achieve these. Let us say you have geographical data in a data.frame such as country, with country identifiers stored in “ip_iso2” column in ISO2 format and the…
I was pleasantly surprised to find out that Arizona State University was a member of AWS educate, more so since my year of free trial ran out last month and I just payed my first bill for the Amazon instance I use for data collection. Amazon Web Services provides an easy to deploy, easy to…
I use Wireshark in my demonstrations for the CIS-430 Networking and Distributed Systems class. I always enjoy the reaction of students when I sniff their FTP passwords off the air. To be able to gather packets in promiscuous mode how ever requires some authorization changes. Here is how I did it the last time I…
