How I got started as a developer (& in Postgres) with Tom Lane
10/11/24 • 99 min
It was not Tom Lane’s plan to become a computer person. Tom’s plan was to be a pinball machine designer. And yet for the last 26 years Tom has been one of the most prolific engineering contributors to Postgres. In this episode of Talking Postgres with Claire Giordano, PostgreSQL luminary Tom Lane walks us through how he got his start as a developer and in Postgres—including his time working on desktop calculators at HP. And how he has code running on Mars (and most of us don’t.) During Tom’s PhD studies at Carnegie Mellon, nobody told him databases were so interesting! It wasn’t until Tom needed a database to store stock trading information that he first got to work with Postgres. And that’s when Tom’s 26-year-long (and counting) Postgres story began.

Becoming a Postgres committer with Melanie Plageman
If you could work on anything, would you quit your job to pursue it? Postgres committer and major contributor Melanie Plageman joined Claire Giordano on this episode of the Talking Postgres podcast (formerly Path To Citus Con) to share her story about becoming a Postgres committer. Melanie pivoted from IT consulting to open-source development, driven by her fascination with systems engineering and Postgres open source. What’s the secret to getting your patch committed? Feedback is a gift, but how willing are you to embrace it? How important is mentorship—and how important is it to ask for help? Even though crafting clear, concise emails to a technical community might not be easy, Melanie shows how empathy for other Postgres developers can help your work to stand out.

Helping Rails developers learn Postgres with Andrew Atkinson
Have you ever achieved something remarkable because someone planted an idea in your mind? In this episode of Talking Postgres, host Claire Giordano talks with Andrew Atkinson—a Rails developer and Postgres user whose journey to becoming a published author began with a simple seed of inspiration. Andrew’s story started with an internal presentation on how to tackle tricky scalability challenges in Rails, grew into a Postgres conference talk at PGConf NYC—and ultimately evolved into his book, High Performance PostgreSQL for Rails. Also in this episode: what does cheese have to do with Postgres? Is writing a good way to think? What’s the connection between Postgres and swimming to Antarctica? And which chapter of his book does Andrew love the most?
