Hari Prasad was using InfluxDB for his personal weekend project as part of his hobby to map the water levels of lakes in his city, rainfall, evaporation index, etc. His Eureka moment: Software development or any human activity flows with time. He started mapping software development at Fujitsu with time series and created an IOT of Software Development. The POC was well-received and obtained funding to be taken to production as a strategic information system. Earlier, developing a similar system for business required huge budget and efforts, whereas with InfluxDB and its ecosystem, the Quality Cost & Delivery was unbelievable. The Flux addition with 2.0 helped Fujitsu with the power of computing, in addition to queries. They build mean, median, Mode, Quantiles with Flux queries and use other built-in functions. The talk will share the Templates, Flux queries, Scraper code to open source community, all of which will be in GitHub where anyone can reference them. The talk will show how quickly, reliably and cost-effectively you can do data-driven software development by writing custom code. It is so generic such that all software development teams from small to large can benefit with little or no maintenance.

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).
