googerteller
Audible feedback on just how much your browsing feeds into Google.
By bert@hubertnet.nl / https://berthub.eu/
Makes a little bit of noise any time your computer sends a packet to a Google service, which excludes Google Cloud users.

How to compile
You need a C++ compiler like gcc-c++
and CMake for compiling the binary.
You also need to install libpcaudio
(libpcaudio-dev
on Debian/Ubuntu, pcaudiolib-devel
on Fedora/Red Hat).
Then run:
cmake .
make
How to run
sudo tcpdump -n -l dst net 192.0.2.1/32 $(for a in $(cat goog-prefixes.txt); do echo or dst net $a; done) | ./teller
And then cry.
Problems
If tcpdump
complains about Warning: Kernel filter failed: Cannot allocate memory
, try
this first:
sudo sysctl net.core.optmem_max=204800
