(she/her) I'm a Developer Advocate by day and YouTuber by night. I like to talk about observability, software testing, learning in public, and taking notes, particularly in Obsidian.

I'm a Filipino-Australian-Dutch cis pansexual agnostic polyglot. If any of that makes you uncomfortable, you probably shouldn't follow me...

Talk to me in: TL EN NL ES EO DE FR IT PT SV. I might not respond fluently after the first five, but I'll respond!

Apparently this astronomical clock in Prague is the oldest working one in the world. Aside from the time as we knownit, it also shows the position of the sun and moon in the sky, the zodiac, Old Czech time, Babylonian time, and sidereal time. This city is amazing. #til

🔴 I'm live with some @grafana@grafana.social colleagues on The Context Window. This time we're talking about MCP, CLI, and other ways that agents can talk to our tools. We're ironing out what those acronyms are and which one's better. https://youtube.com/live/ZR6U4TN8-Cw

In this video, I talk about the AI tools I use for taking notes--including an overkill setup for recording and lifelogging my entire day. Of course, everything ends up in Obsidian in the end! https://youtu.be/2Jl6H9Ri8iI

Whatever you have to say about AI, probably my favourite thing about it is how accessible it makes all software engineering: coding, but also things like monitoring and dashboarding. I rarely write queries anymore, and this video is why. Here's a realistic look at how to get from an empty Grafana Cloud account to a fully visualized dashboard using video game data from a public API... all by just chatting to Grafana Assistant. https://youtu.be/X3TZk_qywlo

Trying something new at work! Here's an excerpt from a real meeting of the Grafana AI team that I'm a part of. In the meeting we often demo things we're working on that might never make it to production. This time it's the latest on Assistant workspace and investigations. https://youtu.be/qts_fkMtdps

We're thinking of this as a way to build in public. It's a little risky, but it's a great way for me to learn how to edit quickly AND to get over the fear of speaking about something half-baked.

Yay an Obsidian video! This one's on how I'm using observability and AI to supplement my PKM system in Obsidian. I gave this talk at PKM Summit in Utrecht earlier this year!

Spoiler: I'm using Grafana and OpenClaw on my notes! https://youtu.be/BeuaPO0Ezuk

Can AI dream? I just published a blog post on OpenClaw's new "dreaming" feature and why it matters, along with my personal experience of it while using my OpenClaw instance. https://contexthorizon.substack.com/p/the-architecture-of-forgetting

Incidentally, this is the missing piece/part 2 to my talk "Do Androids Dream of Second Brains?" at #pkmsummit26 last month! I wish I had been able to talk about this feature then!

Earlier this week, @grafana@grafana.social launched o11y-bench, a benchmark for how well AI agents do for observability use cases. Do we really need yet another AI benchmark? Here's why I think the answer is still yes: https://contexthorizon.substack.com/p/high-int-low-wis-what-llm-benchmarks

Just released this video tutorial for how to enable @grafana@grafana.social's agentic tool, Assistant, for use with Grafana OSS. tl;dr: Assistant is not open source, and you still need a (at least free) Grafana Cloud account, but you CAN now use it for your self-hosted Grafana instance.

Incidentally, I demonstrated how I use Assistant to visualize my Obsidian data in my local Grafana instance at the #pkmsummit26 last month. :)

@DanielBCNA@mastodon.social Ha, thanks, but I'm just very lucky I get to mess around with AI and learn things for a living! And no, it was like that... I saw two other women there (there was an upstairs, another big room, and a patio) but that was it!

Apparently I’m in the top 1% of #cursor users in Lisbon, so I was invited to their Cafe Cursor, where they took over a restaurant for the day and turned it into a coworking space. Got some swag, saw a demo of automations by the Cursor team, and got to talk to some people who were all using Cursor heavily. Great way to learn tips. I’m definitely going to play around with automations! #til

Iris (my OpenClaw instance for processing my Obsidian notes) processed my transcript and notes on giving my talk. She clearly knew I was talking about her, saying "you talked about how *I* helped you do X..." so I asked her what she thought of me talking about her. Here's her response.

Just gave a talk called "Do Androids Dream of Second Brains?: Observability and AI for PKM" where I showed off a super overkill but cool observability stack (with Alloy, Loki, Prometheus, and @grafana@grafana.social) to monitor information from my Obsidian notes--observability isn't just for computer systems! I also talked about how I'm starting to use OpenClaw with my notes, and some initial surprises from that.
