Every city has its own problems to solve; ours had its own.

3
Everything (development) has a cost.

4
City Problem- 1:4 times more rain (inches) than LA. On average, 1 inch more than Seattle annually.
: 40 inches in 60 days is the problem.

Motivation : As a beneficiary of the Development in the city (home). I
was part of the problem too. I felt compelled to give back.
• Constants -- Lake capacity, expected Water from Telugu Ganga Canal.
Variables -- Daily water level, daily water consumption, evaporation
co-efficient, surface temperature, rainfall data, water received from Telugu
Ganga Canal.
Started with Excel sheet, moved to SQL. I was on the lookout for a DB that
would make my job easier. Thanks to Google algorithms & SEO of InfluxDB, I
was frequently seeing InfluxDB.
• Requirement: I had to map every variable with respect to time, Influx made
it absolutely simple.
• Status: The open data on variables was blocked in 2019 as we approached
zero day. Collecting data since 1960s, working on anomaly detection, early
detection of drought with available data.

Pitchdarkdata : An attempt to create visibility to our blind spots.
Who is it for?
Anyone who uses Gerrit: Free, web-based team code collaboration tool developed by Google.
Android OSS development is a notable project on Gerrit platform.
What’s it for?
Provide Engineering analytics and deeper SDLC insights (blind spots) that get buried within
Jira (business cases). Jira/Project Management insights are important but they have a top
view foot above.
How is it done today? What are the limits of current practice?
Emails, gut feeling, Jira data is what’s driving most Org today. There are tools for Engineering
Analytics, but they are expensive & not tailor-made.
Most organizations do not know what is happening under the hood (blind spot).
What are we trying to do?
Democratize data in favor of those who really get the work done. Developers are the heavy
lifters.
What difference will it make ?
Give recognition where it is due, know your bottleneck with data not with emails (biased), PPT
(biased). Provide accurate actionable feedback to developers, Scrum Masters towards
Organizational goals. A great Engineer need not be left behind because of lack of
communication/marketing skills. The system will complement the lack of insight (blind spot).
