Hello Tor, hello world!

Below you'll find the highlights of Tor metrics team work done in
September 2016.

On behalf of the Tor metrics team,
Karsten


Created a database schema and importer [1] for sanitized Tor webserver
logs [2] and wrote two prototypes using RStudio's Shiny [3] to explore
Tor website hits and Tor Browser/Messenger downloads and updates [4, 5].

Tweaked ExoneraTor's [6] English text and corrected the character
encoding to display the German translation correctly.

Completed reprocessing the entire bridge descriptor archive since 2008
to replace TCP ports with hashes, and split up bridge descriptor
tarballs available on CollecTor [7] into one tarball per month and
descriptor type [8].

for making changes like merging multiple descriptors into a single
file or renaming tarballs.
