User community insight using an improved crawler

[synctext]

Goal: a validated, documented and reliable crawler to understand user behavior. This enables the future step of measuring behavioral change.

We have an existing Crawler for Dispersy communities and Tribler. The general Tribler crawler stopped being updated in 2013. See: http://Statistics.tribler.org This is annotated with our releases and major news events. However, totally unmaintained and difficult to maintain.

This crawler needs to move to a proxmox machine and improved. Improved insight will help us understand the network health and roadmap.

Expected results: real-time daily graphs of Tribler network size:

User upgrade behavior:

Examples taken from: http://crawler.doxu.org/uptimes.html

ToDo: NAT type as reported by Dispersy in our community and evolution in time.

According this Github downloads stats we have 302000 downloads of Tribler. http://www.somsubhra.com/github-release-stats/?username=tribler&repository=tribler However, our non-validated, many-years-old crawler only sees a few thousand users.

The thesis of Niels contains an extensive user community evaluation and "data science" portion. http://www.tribler.org/SimilarityFunction/ Thesis.pdf: http://kayapo.tribler.org/trac/raw-attachment/wiki/SimilarityFunction/thesis.pdf

Current setup: Kayapo web space: /var/www/statistics.tribler.org/htdocs/img/ Soft links to: /home/tribler/generate-periodic-statistics kayapo:/home/tribler/generate-periodic-statistics# wc -l *.py 193 first_last.py 191 parse.py 169 reduce.py 553 total

Some crawlers have died a few years ago:
