Marcelo Calbucci @calbucci.com · 30/09/2026It's only based on my prompts. It doesn't change plans without me telling to do it 000
Marcelo Calbucci @calbucci.com · 26/09/2026Officially switching from RunKeeper to Strava to record my runs. I've been with RunKeeper for 15+ years, but the lack of an API and an MCP sealed the deal. 000
Marcelo Calbucci @calbucci.com · 26/09/2026Yes, it decides for me. I only scan the plan, but mostly trust it to decide my training schedule. 100
Marcelo Calbucci @calbucci.com · 24/09/2026I built my personal fitness display, a website to manage my training plan, and an MCP to let Claude control everything and adjust my plan according to my races, weather, etc. I believe that in the next decade we'll see a renaissance for the arts, science, technology, industry, and humanity. 300
Marcelo Calbucci @calbucci.com · 23/09/2026At this point, I don't want better frontier models. I want faster (!!!), cheaper, and less-error prone models. 000
Marcelo Calbucci @calbucci.com · 17/09/2026I'm looking forward to an AI agent that can organize and consolidate the decades of notes and files we have on OneNote, Notion, Google Docs, Dropbox, OneDrive, Notes App, and everywhere else. To answer your question, no, I won't use Muse, OpenAI, Claude, or Gemini. It has to be a local LLM. 420
Marcelo Calbucci @calbucci.com · 14/09/2026People are handing full access to their emails, documents, and calendars to "unknown" AI agent startups and to corporations with a checkered past of privacy violations. 040
Marcelo Calbucci @calbucci.com · 03/09/2026I'm old enough to remember when GPT-3.5 launched, and people said when GPT-5 launches the entire world is cooked. The jobs would be gone, society would collapse, Skynet would be here…Now LLMs struggle to have two-9s of availability. 010
Marcelo Calbucci @calbucci.com · 03/09/2026I'm going to make many tech solopreneurs upset when I say this, but you don't need Linear, branches, PRs, CI/CD, or staging until your product has meaningful traction. 021
Marcelo Calbucci @calbucci.com · 02/09/2026Folks, I'm not sure Amazon offers the best prices. I bought a product directly from the manufacturer, paid $8 for shipping, and the total came out to $35. On Amazon, with free Prime shipping, it was $47.49. 040
Marcelo Calbucci @calbucci.com · 31/08/2026What happens when this president decides to rename countries? 000
Marcelo Calbucci @calbucci.com · 19/07/2026Haaland, Vozinha, and Bellingham are the super heroes of this World Cup. It's not even a contest. 030
Marcelo Calbucci @calbucci.com · 14/07/2026BREAKING: Company led by a leader with low morals does a bad thing. 020
Marcelo Calbucci @calbucci.com · 10/07/2026With Claude Code, you are on the edge of your seat. You don't know if it'll crash, the API will error out, if you hit the usage limit for the period, or if it'll build an amazing feature. 270
Marcelo Calbucci @calbucci.com · 30/06/2026This is the first World Cup that you learn about a team scoring in the group chat before you see it on TV. 010
Marcelo Calbucci @calbucci.com · 25/06/2026LinkedIn Games is what happens when your strategy gets disconnected from your customer. Games -> Attention -> Ads -> Revenue. How does this align with their vision of "creating economic opportunity for every member of the global workforce"? This is what Eric Ries calls "corruption" in his new book. 110
Marcelo Calbucci @calbucci.com · 17/06/2026This is the first World Cup with mass TikTok use, prediction markets, and AI. 100
Marcelo Calbucci @calbucci.com · 16/06/2026Someday I'll tell my kids the fable of the three days of Fable. 000
Marcelo Calbucci @calbucci.com · 14/06/2026Not enough people know the expression "Bread and circuses." 031
Reposted by Marcelo CalbucciJeremiah Chronister @jeremiahchronister.bsky.social · 28/04/2026Love this. Unfreezing founder energy is the real multiplier. Those connections compound over years. 0111
Marcelo Calbucci @calbucci.com · 28/04/2026The conference is sector-agnostic. The goal is to connect people, help them learn from others, see what's possible. I'm doing my part to unfreeze founder energy. 240
Marcelo Calbucci @calbucci.com · 28/04/2026Fair point on Seattle leaning bigco/safe. But the speakers aren't that. Rand Fishkin, Patrick Thompson, David Shim, Ambika Singh, Aaron Bird, Marius Ciocirlan. All operators who took great risks. 110

Marcelo Calbucci @calbucci.com · 22/04/2026UNBREAKING: PRDs are not dead. It has a new shape, but still is a PRD. 020
Marcelo Calbucci @calbucci.com · 21/04/2026If you take the blip from the pandemic, Seattle has had the lowest # of investment deals in a decade (since 2016 Q4). The situation is worse than it appears because the total number of deals in the US has grown 40% since 2016. I have several theories, but I want to hear what you think is going on. 110

Marcelo Calbucci @calbucci.com · 12/04/2026I don’t think there’s ever been a time that so clearly separates people with a growth mindset vs. fixed mindset. 240
Marcelo Calbucci @calbucci.com · 09/04/2026The current conversations about AI remind me of when we first controlled fire, 400,000 years ago. “Do we really understand fire?” “Will fire take our jobs?” “Can fire be trusted? What if it burns us?” “What if fire is just hype?” 121

Marcelo Calbucci @calbucci.com · 06/04/20266,000+ tech layoffs in Seattle. Amazon, Microsoft, Oracle, Meta. You don't need permission to start a company. You don't need all the answers either. You need to learn from founders who've done it recently. That's why I'm putting together @seattleflow.org Startup Day! 4143
Marcelo Calbucci @calbucci.com · 06/04/2026The only reason Claude Code doesn't cost $2,000/month on the Max plan is Codex. 130
Marcelo Calbucci @calbucci.com · 04/04/2026Even if doctors don't adopt AI, medicine has changed forever already.
