A Close Look at a Visual Studio 2015 Generated V-Table (C++)

As I mentioned in an earlier blog post on analyzing disassembly, it's sometimes really helpful to know what exactly is happening at the machine level of C++ code I write. This includes knowing how the vtable works.

Sometimes it's really useful to be able to see exactly what's happening behind the scenes of the C++ code I write. I've been spending some time on my sabbatical doing this.

Thoughts on "Scrum: A Breathtakingly Brief and Agile Introduction"

I really like a lot of the ideas behind scrum and agile principles in general. I've made it a point to devote some of my time during this sabbatical to educating myself farther in these topics.

I was recently browsing through books on agile when I came across "Scrum: A Breathtakingly Brief and Agil

My Tiva Launchpad Simple Drum Machine

I've completed my next Tiva LaunchPad project. I created a simple drum machine. Press a button and an audible 8-bit drum sample is played back. A video explaining and demoing it is below. A link to the C program I wrote which runs on the LaunchPad is given below as well.
