🚀 Introducing AI agents that make “self-driving” machine learning usable by anyone — no PhD required. A lifelong dream for me, launched in months… Demo below! Forecasting, key driver analysis, predictions, tipping-point analysis, and anomaly detection now take minutes instead of weeks. 🤖 ✨ To my knowledge, we’re the first team in the world to ship autonomous machine learning (AutoML) guided by an agent — or “agentic AutoML” — usable by anyone. Genuinely in awe of the creativity, ingenuity, and grit every @SpindleAI teammate poured into making that possible. 🙏 With transparent, personalized explanations for “how”, “why,” and “what next,” the new agent also delivers actionable recommendations for setting & hitting business targets 🎯 based on patterns in your data. From churn prediction & customer behavior forecasting, to pricing simulations & cross-sell targeting, beta customers are already sharing compelling use cases with us… But most of all, I’m excited to see all the creative use cases YOU come up with: spindle.ai/agents/autonomous…

Daily precipitation amounts in Weather Strip now include rain and snow icons for clarity (below the weekly timeline). 💧❄️ You can enable daily precipitation from the app settings screen. Lack of a number signifies little or no significant accumulation that day.

Call me optimistic – I used to think AI would help prevent spam, not boost it to the top of my inbox

Maybe Apple will cast the new Mac Pro as a power tool for creating content for the VR headset.

I like the framing that strongly typed languages essentially write a class of unit tests for you. Which makes up for the time it takes you to define all the types. Via @ryanatallah
