Welcome! I’ve been profiling software developers via photos, videos, and podcasts for a long time. So, I figured I’d start collecting some of that content here on this site along with my own work building Open Source software communities. I have hundreds of images under photos and thousands more on Flickr. And beyond the images you’ll find hundreds of interviews as well. I also talk about money, geopolitics, science, and biomedical issues. Follow the navigation links on the left and poke around and let me know what you think.
Most of the content I post these days on this blog comes from my work at Oracle, but that will fade now as my career changes and as I get into more of my own personal interests. Previously, I used to blog at Sun Microsystems on blogs.sun.com, but all of that fun ended abruptly after the Oracle acquisition in 2010. I wrote thousands of posts for Sun during those years, and thankfully that content still lives in the Internet Archive. I really loved that blog! It’s a shame how it ended. Anyway, everything below sums up some key projects I’ve run and also what I do these days in the developer community.

Briefly
I’ve managed projects in software, biotech, publishing, and construction. I’ve navigated multiple economic and political systems, sparred with some overtly hostile unions, survived a few near-death experiences, and overcame serious medical limitations. I’m lucky to be alive and thankful to be walking.
I ran my own excavating and real estate development business, and I was also a mechanic, truck driver, and landscaper. After everything crashed and burned I picked up the pieces, went back to school, and eventually became an editor, a writer, and a publicist. I’ve worked with the global news media, and also U.S. local, state, and federal government officials; I’ve interviewed hundreds of engineers, scientists, and biomedical clinicians; and I’ve produced thousands of articles, photos, videos, and podcasts that have reached millions of people.
In recent years I’ve built FOSS communities at Sun and Oracle, managed developer events globally, profiled engineers, and delivered my own community sessions at conferences around the world.

Full Bio
Jim Grisanzio worked at Oracle on the Java Developer Relations Team in the Java Platform Group, which is the engineering organization building Java. He hosts the Duke’s Corner Podcast, published the Inside Java Newsletter, produced video and photography, facilitated the Java User Group and Java Champions programs, delivered community sessions at events, and contributed to the team’s community development programs.
In recent years while in Oracle developer marketing, Jim managed the Oracle Developers YouTube channel and multiple social media platforms. He also hosted the Oracle Groundbreakers Podcast, produced videos and live streams, delivered presentations, managed events, and published the Database and Java newsletters. From 2017 to present Jim has interviewed more than 450 developers via live streams, podcasts, and videos on a variety of technologies including Java, Linux, Oracle Database, MySQL, AI/ML, Developer Tools, Cloud, and Open Source.
Before Oracle developer marketing, Jim worked in Solaris engineering managing FOSS projects delivering into the operating system. He was also the OpenSolaris Community Manager at Sun Microsystems from the project’s inception until the acquisition by Oracle. He directed Solaris engineering projects with corporate partners, managed Linux and OpenSolaris user groups, presented at universities and conferences, briefed press and analysts, and ran developer events. Earlier at Sun, Jim managed competitive marketing campaigns for all of Sun’s Open Source and Open Standards projects. He also wrote keynote speeches and managed communications for Sun’s CMO and other senior executives.
Jim’s academic background covers science and technical writing, publications production, health care policy, and history. He’s edited software and medical newsletters; written hundreds of magazine articles and press releases; and collaborated with engineers, scientists, physicians, and veterinarians in academia and biotechnology. He’s also worked with the global news media and American government officials at local, state, and federal levels — including The White House — while running hardware, software, and biomedical publicity programs for multiple companies and universities.
Jim’s foundational experience in managing complex projects came from working in the real estate development business in New York. He sold residential homes and raw land; hired and managed construction crews; acquired the legal and financial approvals necessary for building; managed the construction process on site, configured mortgages for customers, and worked closely with political, municipal, regulatory, and banking officials to finalize closings. He also ran his own excavating and trucking company — he secured financing and purchased equipment worth hundreds of thousands of dollars; worked on hundreds of commercial and residential sites; negotiated contracts with all stakeholders; and managed operations with customers, vendors, governments, and unions.
Jim knows well what it’s like for everything to crash completely and require rebuilding from scratch. That’s why he has a varied background. He never gives up. He just keeps building.

I’ve done whatever was necessary to push the project forward, contribute to my team’s efforts, and build the developer community.

Podcasts, Videos, Newsletters
Duke’s Corner Java Podcast
- Libsyn Audio | Podcast Video | Highlights on X | Abstracts, Quotes, Transcripts
Duke’s Corner was the name from 2022 to 2026. The podcast was previously called Oracle Groundbreakers and also Oracle Techcast and the 400 episodes go back to 2011. I took over the platform in 2020. Also note that for inexplicable reasons the Duke’s Corner videos are “unlisted” on the Java YouTube channel so they are effectively hidden. I will republish them myself.
Oracle Developers Interviews (Archive)
- 315 video interviews for the Oracle Developers YouTube channel
This channel is no longer active since I moved to the Java Platform Group in 2022. Also note that as of July 2023 someone for inexplicable reasons deleted over 100 videos. Deft. I will republish them myself.

Oracle Code Innovate
From 2018 to 2020, I served as Scrum Master at four week-long hackfests in the United States and India called Oracle Code Innovate. The program brought Oracle engineers and customer developers together to build working cloud prototypes in three intensive days. No slide decks, no proof-of-concept theater. Just real engineers solving real problems side by side, on Oracle Cloud Infrastructure (OCI). This was probably the best program I worked on at Oracle because it combined the work of engineering, community building, and revenue generation. Check out this blog post for more details, videos, podcasts, and photos.
Solaris Project Management
This was the period from 2011-2016 after Oracle canceled the OpenSolaris project right after the acquisition of Sun Microsystems. During the reorgs I was moved from doing external OpenSolaris community development to instead focusing internally as a program manager in Solaris engineering on the following projects:
- Solaris Userland FOSS Consolidation
- Solaris Core Quality Engineering
- Solaris Unix Commands Project
- Solaris OpenStack Project
- Solaris V8 Project
- Solaris POSIX Standards Project
- Solaris Core Innovations Workshop
I learned a great deal about engineering project management and product development during this period. But all of that ended abruptly right at the end of 2016. Then in the spring of 2017 I moved into corporate marketing to work on global developer programs, which is outlined earlier on this page.
