    Google Introduces Option to Change Your Gmail Address

    Google now allows Gmail users to change their @gmail.com email addresses while keeping the old address as an alias. Users can change their address up to three times with a mandatory 12-month waiting period between changes. The old address continues to work for receiving emails and signing into Google services. The feature is rolling out gradually and currently documented only on Google's Hindi support page.

    I switched to eSIM in 2025, and I am full of regret

    eSIM technology is replacing physical SIM cards in modern smartphones, with Google's Pixel 10 series becoming the latest to drop the physical SIM slot. While eSIMs save space and allow multiple profiles, the transition has proven frustrating for users accustomed to easily swapping physical SIM cards. Apple pioneered the eSIM-only approach with the iPhone 14, though the space savings have been modest—around 8 percent more battery capacity. The shift represents a significant change in how mobile subscribers manage their phone service, moving from removable cards to programmable, soldered components.

    Google's vibe-coding tool Opal comes to Gemini

    Google is integrating Opal, its vibe-coding tool for building AI-powered mini apps, directly into the Gemini web interface. Users can now create custom apps (called Gems) using natural language descriptions, with a visual editor that arranges steps without writing code. The tool includes a new view that converts written prompts into step-by-step workflows, and advanced users can access more customization options at opal.google.com. This move positions Google alongside other AI-powered app-building tools like Lovable, Cursor, and offerings from Anthropic and OpenAI.

    Introducing Agent Development Kit for TypeScript: Build AI Agents with the Power of a Code-First Approach

    Google released Agent Development Kit (ADK) for TypeScript, an open-source framework for building AI agents and multi-agent systems. The code-first approach lets developers define agent logic, tools, and orchestration directly in TypeScript, applying traditional software development practices like version control and CI/CD. While optimized for Gemini and Vertex AI, ADK is model-agnostic and supports third-party tools. It includes native integration with MCP Toolbox for database connections and supports the latest Gemini 3 models.

    openai is getting desperate

    OpenAI faces increasing competition as Google's Gemini gains ground, with notable users like Salesforce CEO switching platforms. The company secured a $1 billion Disney investment for Sora video generation rights while simultaneously getting Disney to issue a cease-and-desist to Google. The launch of Images 1.5 received mixed reactions, with critics noting quality issues. OpenAI no longer leads in most AI categories as competitors catch up, causing users to migrate to alternative platforms offering better models and features.

    What Gemini 3 Pro Changes About Product Design

    Google's Gemini 3 Pro introduces Generative UI capabilities that transform product design workflows by converting sketches directly into working prototypes in seconds. The model demonstrates multimodal synthesis, agentic design system thinking, and aesthetic control that enables designers to move from concept to interactive interface without traditional handoff processes. Early adopters report 35-50% improvements in frontend task completion, with the AI functioning as a design collaborator rather than just a code generator. While implementation times and premium access remain limitations, the technology is already collapsing week-long design cycles into days and shifting designer focus from implementation details to strategic design thinking.
