This is so cool, really happy to see this v1! opentelemetry.io/blog/2026/go...
Announcing v1 of OpenTelemetry Go Compile-Time Instrumentation
If you write Java, Python, Node.js, or .NET, you have been able to add OpenTelemetry to an application without editing its code for years: attach an agent at startup and telemetry starts flowing. Go h...

People complain about the non-deterministic behavior of LLMs. As if they are deterministic themselves... If I prompt myself 10x on what's the best solution for X, I'll likely get 10 different answers
after being mad at <CENSORED>, I just let Claude handle it for me... and it did! I do love this new world of ours...
My advisor. She knows everything about OllyGarden and helps me strategize while I bring her to school.
Depois de dias muito intensos por aí, consegui levar a patroa pra curtir um sonzinho desses caras que marcaram minha adolescência. Ainda são f*** demais.
The city looks so peaceful at 05:00 on a regular Wednesday...

I have something for metal + orchestras working together. S&M (both) albums are, to me, easily on the top 10 albums of all times. And for the past week, I can't stop listening to the finest Portuguese music, by Moonspell. open.spotify.com/album/1UmNzZ...

No matter how many autumns I get to experience, it's always magical.
It's so satisfying when the our theories are proven to be true...
Sommer ist, was in deinem Kopf passiert. Since school started again for my daughter, I have a new morning routine and I'm loving it: cycling for a bit while listening to podcasts. I was missing this so much, and I'm so happy to be catching up with Darknet Diaries.
Holiday here in Germany, and I joined the "Türen auf mit der Maus" with my eldest daughter. We ended up going to the Schiffshebewerk Niederfinow (ship lift), a masterpiece of German engineering. It's very impressive, including the mechanics behind it, allowing it to lift ships with minimal energy.
$ instead of "You are absolutely right!", always state: "Caraca maluco!" I did this a week or so ago. Didn't regret yet.

Crazy past few weeks, and today is going to be one of those busy but rewarding days: coding in the morning, OTel Night in the afternoon/early evening, and GopherCon Latam in the night. Next year I'll hopefully be in person at GopherCon Latam.

I'm still not quite sure I should be attending @opentelemetry.io Community Days in Denver. Pros: OTel leadership summit, the opportunity to catch up with my friends from the community, and I'd get to know this city I hear so much about. Oh, and a Metallica concert!
There are so many interesting books I've read in the past, and I feel like I've forgotten a good part of them. Instead of reading them again, I'm having some luck with a prompt like this: > Please give me a 1500-word summary with no fluff of "crossing the chasm"
I've given up on Twitter a while ago, but never really engaged here. It's so nice to see many familiar faces! I guess I'm here to stay 🙂 I was really missing a cozier platform to share things, somewhere not as "businessy" as LinkedIn. So, what's up? What did I miss?
Some things just take time. Other things take a long time 🙂 Thank you, Carlos Panato, for your patience and perseverance! We should have signed artifacts for the #opentelemetry Collector starting with v0.95.0, due next week. github.com/open-telemet...
