Episode 114: Christof Ebert on Requirements Engineering

In this episode we talk to Christof Ebert about requirements engineering. As the name "engineering" suggests, we need to be systematic when working and managing requirements. Christof will structure RE into several activities, namely elicitation (identifying the relevant requirements), specification (clearly describing requirements), analysis (synthesizing a solution), verification and validation (achieving good requirements quality), comittment (allocating requirements to a project, product release or iteration), and management (keeping track of the implementation status of requirements). In this episode we discuss these activities and highlight lots of practical guidance.

Cheating Your Way Through High School and College: The Numbers

Academic cheating seems to be growing at an ever alarming rate. Cheating occurs at every level of education and certification and it includes students, educators, and administrators. Technology has also given cheaters new methods for cheating and, unfortunately, you can find most of these methods demonstrated on YouTube (you can find additional resources on cheating HERE).

Best College Reviews created an interesting infographic about cheating in high school and college that I wanted to share with you. They provide resons for cheating and how cheating occurs among other interesting factoids.

Please take a look at their website to find additional resources on cheating (listed below the infographic).
