My Tiva LaunchPad Powered Sine Player (Video Included)

A while back I mentioned I had been reading up on ARM Cortex-M microcontrollers and obtained a Texas Instruments Tiva LaunchPad (aka "Tiva Stellaris"). The Tiva LaunchPad has an ARM Cortex-M4 chip onboard. I've completed my first small project: An audible sine wave player whose tone is controlled…

Thoughts on "Software Estimation: Demystifying the Black Art" by Steve McConnell

I've never had any formal training in software estimation and my hunch is that many of the software developers and engineers I've worked with over the years haven't either. That's not a knock against them, many of them are highly qualified. If anything, it's more a commentary on the typical career…
