Well, dspGuru will be ten years old in a few days. It hardly seems possible. It's interesting to look back on how it turned out relative to what I was hoping for when I launched it. dspGuru has mostly been a success. At the most basic level, it scratched an itch that I had - and still have - to spread the gospel of DSP. Of all the missions one might adopt to make the world a better place, helping folks learn DSP pales in comparison to ending polio and squashing sugar ants. But we all need a mission.
