  But when iterating on a non-trivial package locally, I will usually build the package directly on my Debian testing system, and I want to take advantage of ccache to cache native (C/C++) code compilation to speed things up. In Debian, the easiest way to enable ccache is to add /usr/lib/ccache to your $PATH. I do this by doing something similar to the following in my ~/.bashrc: [...]

• Hackaday ☛ Reverse Engineering The Web API Of An Akaso EK7000 Action Camera

He provided a fake camera WiFi hotspot for the app in order to learn its secrets.
