On this weeks episode of the podcast, freeCodeCamp founder Quincy Larson interviews Jerod Santo, host of The Changelog, a podcast about open source software development that has been going strong for 15 years.
Jerod is plugged in to the world of Open Source, going to all the big conferences and interviewing all the big open source creators.
We have a fun, wide-reaching conversation about some of the current issues facing open source, such as AI models and Relicensing – essentially, a big company closed-sourcing a previously open source project after they buy out its creator. (Fun fact: this cant happen to freeCodeCamp because charities cannot be bought or sold.)
I ask Jerod about:
- his life as a remote dev in Omaha, Nebraska, raising his 6 his kids
- the Changelog News podcast with its weekly 10 minutes of updates on the world of open source
- his process, and how he researches and surfaces interesting news for his show
- and how The Changelog commissioned 3 full albums worth of music over the years, which you can stream for free.
Can you guess what bass line Im playing during the intro? Its from a 1984 pop classic.

On this weeks episode of the podcast, freeCodeCamp founder Quincy Larson interviews Hiroko Nishimura. Shes a special ed teacher turned system administrator turned technical instructor.
Hiroko grew up in Japan and moved to the US as a kid. In her early 20s, she was diagnosed with a vascular tumor in her brain. After life-saving surgery, she had to work to regain the ability to walk and talk. She still lives with disabilities to this day.
Despite this, shes gone on to author technical books, become an AWS hero, and create the popular AWS Newbies community. More than 500,000 people have taken her LinkedIn Learning course.
We talk about:
How Hiroko moved to the US as a kid and learned English and American culture
Hirokos vascular tumor diagnosis, and how she recovered from brain surgery and brain damage
Her big move to NYC and her years working as a system administrator and ultimately cloud engineer there
How she made the jump to teaching system administration full-time as a course creator

On this weeks episode of the podcast, freeCodeCamp founder Quincy Larson interviews Ken Jee. Kens a Data Scientist. Hes also a Sports Analytics practitioner who works with US Team Golf and USA Basketball.
Ken hosts the excellent Kens Nearest Neighbors podcast and the Exponential Athlete podcast.
We talk about:
- How an injury pushed Ken out of pro sports and into data science
- How Ken explains his statistical insights to coaches and players to help them improve their performance
- Why Ken doesnt think building projects is all that useful anymore. Data Scientists should instead build products.
- How Ken starts and ends each day with meditation, and writes down all the ideas that pop into his head after each session.
- Kens observation that: Who is the best suited to excel in a world where AI tools are prominent? Probably the people who are building them. People in the data science domain, people who are coding – theyre the most prepared to use these tools for other things.
Can you guess what song Im playing on my bass during the intro? Its from a 2006 dance song, and it was originally played on a synth.
