Hey! I’m Daniel Kossmann ꩜,
welcome to my Public Learning (b)Log.

- Professional Journey: I work as an AI Product Manager at Extendify and have a background as an Engineering Manager and Full-Stack Web Developer.
- WordPress Expertise: Over 15 years in the WordPress ecosystem, I have been featured in People of WordPress and have organized monthly community meetups for 7 years.
- Interests: Product Management, Artificial Intelligence, Productivity, and WordPress.
- Content Creator: In addition to this blog, I’ve been writing PainelWP, a weekly newsletter about WordPress in Portuguese, since June 2019.
- Hobbies: I love watching movies and wrote reviews as a hobby for a few years. I also enjoy drawing, especially with watercolors.

Raycast has this cool extension to control Spotify, so I searched for something similar for uLauncher. I ended up getting the Spotify player extension working, which lets you pause, play, and skip to the next or previous track. It’s not as advanced as the Raycast extension, but since it doesn’t use the Spotify WebAPI, the…

Next, open a file in VS Code—you’ll see a VS Code icon and the filename above the ChatGPT Desktop chat input.

I’ve used Linux as my main Operating System for over 20 years, and just started using macOS for work this year (2025). I’m treating it as a research experiment—to see how another OS works and look for ways to improve my Linux setup (which I already have—like using pbcopy/pbpaste, and recently, the trash command). I’ll…

Here’s how I installed Arize Phoenix, an open-source AI observability and evaluation tool, using the uv package manager: To open it in the future, just run the following commands:

WP-CLI uses the same locale as the WordPress installation, so if you deal with multiple locales, it might be tricky to follow the output. Luckily, the official documentation shows how to set a specific locale. Here’s a quick summary, plus an important caveat I found: 1. Create a file called force-locale.php and set your desired…

I made a simple plugin with AI’s help that I use locally, so I don’t have to log in as administrator every time I reset a WordPress site to run tests. The initial plugin code had the credentials hard-coded, but before sharing it, I changed it to fetch the first admin user from the database.…
