JetBrain’s The State of Developer Experience and Developer Productivity survey is out. It’s an oddly, narrowly focused survey. Mostly on metrics used to measure developer experience. Above, the metrics most used for tracking/rating/metric’ing development..As the conclusion says, measuring DevEx is getting better: The good news is that companies are getting more serious about tracking developer experience, not just productivity. The drop in irregular DevEx assessments – from 53% in 2024 to 29% in 2025 – shows a positive shift toward more structured and thoughtful measurement.

We don’t tell Cloud Foundry stories enough. Here are four: This talk was also a request to make more “case studies” and “customer references,” that is stories. So, I try to go over how to do that as well. At the last Cloud Foundry Day, I spoke more generally about the need for more Cloud Foundry marketing. Maybe I’ll become “that one guy who talks about Cloud Foundry marketing at CF Day”…if they let me.

AI-generated videos and images could be significantly “better” without current technological and content restrictions.

There’s a new study out that means it’s time to update all those slides that say AI projects are failing: [A] new study from the University of Pennsylvania’s Wharton School complicates the narrative. The study found that 74% of businesses that measure the ROI from their generative AI efforts are already seeing a positive return, and more expect to see a positive ROI within the next two or three years.

180 million-plus developers now work and build on GitHub. Their definition is “[a]nyone with a GitHub account.” Let’s not overthink it, just yet, and instead go with what they’re saying. If 2025 had a theme, it would be growth. Every second, more than one new developer on average joined GitHub–over 36 million in the past year. It’s our fastest absolute growth rate yet and 180 million-plus developers now work and build on GitHub.

Plus, a lot of talk about Java and Spring in large organizations.

I’m always trying to find how many apps are written (and, of course, running) in Java. Here are recent numbers I have on hand: “[N]early 70% of respondents say that more than half of their applications are built with Java or run on a JVM.” Azul survey, 2025. “98% of companies we surveyed use Java, with 57% saying it is the backbone of most of their application and infrastructure estate.

Here are some thoughts after a week of using Claude Skills. JasonJ in the SDT Slack says: I’d tl;dr Claude CLI skills as “low/no/english code MCPs'”. Seems helpful in the way that local utility scripts are today. That is a good way of putting it. I haven’t done heavy experimenting, but I think there’s a distinction between: (1) The Skill has no code, except maybe code fragments. Most of it is just a SKILL.
