So, if you know a little HTML, you can write a simple diagnostic page for your drone, or a product page for it.

If you know a little SQL, you can throw a SQLlite database on the drone to easily track points and query the data of multiple drones being collected.

If you know ARM assembly, you can write optimized math routines for your MMO running on mobile clients, or on low-power boards in a server farm. Or figure out why your web server is crashing in weird ways on your server. Or why certain overflows in your tax software aren't being trapped.

"Full stack" means knowing about the rest of the tools so you can improve things beyond what CodeProject would let you do.
