Support CleanTechnica’s work through a Substack subscription or on Stripe. Each time we see a photograph of bleached coral reefs, we feel saddened — there is no greater iconography of the climate crisis that surrounds us. The United Nations warned this month of a “deepening crisis” for oceans, outlining a trajectory of intensifying heat absorption, pollution, and overfishing. Then again, there may be hope for some of the world’s corals, as scientists are working feverishly to replant coral reefs. “Can’t install good over bad,” your grandpa would insist? Grandpa is still correct. This time, however, heat-tolerant corals could be the…

Meta is betting on India for WhatsApp’s next chapter, naming entrepreneur Kunal Shah to lead the messaging app and succeed Will Cathcart, who is stepping down after nearly seven years at the helm to take on a new product-building role at the company. The move comes alongside a Meta-led $900 million financing for Indian fintech giant CRED, structured through a combination of primary and secondary share purchases. The deal will make Meta a minority investor in the CRED, which said Shah will step down as chief executive while retaining his personal shareholding. India is WhatsApp’s largest market, with more than…

Danny Yang and Sam Goldman, both Software Engineers at Meta, speak with host Gregory M. Kapfhammer about the Rust-based Pyrefly type checker for Python.

Antigravity CLI is the newest agentic coding CLI from Google, replacing the now-deprecated Gemini CLI. It inherits the asynchronous subagent model that makes Antigravity stand out from the field, syncs bidirectionally with Antigravity Desktop, and is optimized for speed on Gemini 3.5 Flash. DataRobot ships a full plugin for Antigravity CLI directly from the same open source repository that powers our Cursor, Claude Code, and Gemini CLI integrations. One install gives you the complete DataRobot skill set inside Antigravity’s agent and slash-command interface. Install the DataRobot plugin with a single command: agy plugin install If you’re still on Gemini CLI,…

ML system design interviews test how well you can think beyond models. In these interviews, choosing an algorithm is only one part of the answer. You also need to explain how data is collected, how features are created, how predictions are served, and how the system improves over time.  Most real ML systems are built around product decisions. A feed system decides what to show. A fraud system decides what to block. A search system decides what to rank. This article walks through 10 such problems in a practical interview style.  How to Think in an ML System Design Interview…

Every CIO faces the same question right now: how do you secure an AI-powered, distributed workforce without adding more complexity to an already overloaded team? Cisco IT faced that question—and built the answer. In 12 months, Cisco IT reduced help desk cases by 18%, cut security incident rates to near zero, and eliminated 20+ legacy VPN options—all while securing AI adoption at scale. Here’s how they did it, according to the engineers. In previous blogs, we explored the strategic imperative behind Cisco’s shift to a Zero Trust architecture and examined the organizational blueprint that guided our phased migration to a…
