Google deleting all recently inactive accounts without phone number

Google is now deleting all accounts that do not, and have never had, phone numbers associated with them if they haven't logged in within a year or so. "Urgent: Sign in to your Google Account if you want to keep it" But then it doesn't matter if you log in with the correct username and password and receive the PIN via your email. This is isn't enough. Unless a phone number is somehow added to the account one gets, "You can’t recover your account at this time because Google doesn’t have enough inf

The Ultimate Claude Masterclass: 13 Power Features Changing the AI Game

The Ultimate Claude Masterclass: 13 Power Features Changing the AI Game Artificial Intelligence is no longer just about asking questions and getting text answers. Anthropic’s Claude has evolved from a simple chatbot into a fully autonomous, visual, and connected AI ecosystem. If you are still using it just to draft emails, you are barely scratching the surface. Whether you are a developer, content creator, or business professional, here is your definitive guide to the 13 powerhouse features of Claude, packed with practical examples, formatted specifically for Dev.to. 🧩 Part 1: Smart Onboarding & Personalization 1. Introduction to Claude Claude stands out in the crowded AI landscape because of its advanced reasoning, high emotional intelligence, and natural, human-like writing style. From parsing complex codebases to writing creative narratives, Claude feels less like a machine and more like a brilliant colleague. 2. Import Memory From ChatGPT To Claude Switching platforms shouldn't mean losing your progress. With this feature, you can instantly migrate your entire persona, past context, and custom instructions from ChatGPT straight into Claude with a single click. Example: If ChatGPT already knows your coding style or specific brand rules, importing it means Claude hits the ground running without you having to re-explain everything. 3. Add User Preferences Tired of typing "Act as a Senior Developer" or "Keep it casual" in every single prompt? User Preferences lets you set permanent system-level instructions that Claude remembers across all new conversations. Example: You can set a preference like: I manage a technology brand. Always keep explanations direct, modular, and optimized for scalability. 🎨 Part 2: Visuals, Coding & Apps 4. Create Apps & Artifacts Using Claude For Free Claude’s Artifacts feature opens a dedicated, interactive window right next to your chat. When you ask Claude to write code, a webpage, or a game, it doesn't just show you lines of text—it re

How to Thrive (Not Just Survive) as a Developer in the Age of AI

The narrative around Artificial Intelligence and software engineering has shifted dramatically. We are no longer asking if AI will change development, but rather how we change with it. If your value as a developer is tied solely to how fast you can churn out boilerplate code, write standard API endpoints, or memorize syntax, the landscape is becoming challenging. AI can do those things in seconds. However, this isn't a death sentence for the engineering career—it is an evolution. The industry is moving away from pure "code generation" and shifting toward system architecture, integration, and governance. To remain indispensable, you need to know exactly where to direct your energy and what pitfalls to avoid. Where to Focus Your Energy To stay relevant, you must position yourself in the areas where AI struggles: high-level abstraction, complex contextual reasoning, and human leadership. 1. System Design and Enterprise Architecture AI is excellent at writing isolated functions, but it struggles with massive, interconnected systems. Focus on how components interact at scale. Understanding how to slice a monolithic application into resilient microservices, orchestrate microfrontends, or design cloud-native solutions is where the high-value work lies. 2. Code Governance and Quality Assurance With AI generating code at unprecedented speeds, codebases are expanding faster than ever. The world doesn't just need people who can create code; it needs gatekeepers who can validate it. Your role will increasingly focus on setting quality standards, establishing robust CI/CD pipelines, and ensuring that AI-generated code adheres to strict security, compliance, and performance metrics. 3. Mentorship and Team Leadership The influx of AI tools means junior engineers can produce code much earlier in their careers, but they often lack the foundational experience to spot subtle architectural flaws or security vulnerabilities. Senior developers must step up as leaders, guiding less experi

How to Prove a Prediction Was Made Before the Event (with OpenTimestamps)

Everyone who has ever been right about something loud enough to remember it will tell you they called it. The screenshot arrives after the match, after the candle, after the election. And there is no way to know whether it was written on Monday or edited on Friday. This is the quiet rot at the center of most "track records": a prediction you cannot date is not a prediction at all. It is a memory with good lighting. The technical name for the problem is look-ahead . If a forecast can be created, tweaked, or cherry-picked after the outcome is known, then it carries zero information about skill. The only fix is to make the timing of a prediction independently checkable вАФ to prove a document existed in a specific form before a specific moment, without asking anyone to trust you, your server clock, or your database. That is precisely what OpenTimestamps does, using the Bitcoin blockchain as a shared, tamper-evident clock. Why timing is the whole game A forecast is a bet against the future. Its value comes entirely from the fact that the future was unknown when the forecast was fixed. The instant you allow post-hoc editing, every desirable property collapses: calibration becomes meaningless, Brier scores become fiction, and "I predicted this" becomes unfalsifiable. So an honest forecasting system needs one hard guarantee before anything else: this exact text existed at this exact time, and has not changed since. Note what that guarantee does not require. It does not require publishing the forecast publicly in advance (you might want it sealed). It does not require a notary, a lawyer, or a trusted timestamping company that could be subpoenaed, hacked, or simply go out of business. It requires a clock that nobody controls and nobody can wind backward. What "proof of existence" actually means The building block is a cryptographic hash вАФ typically SHA-256. Feed any file into it and you get a 64-character fingerprint. Change a single comma and the fingerprint changes compl

A Beginner's Guide to Installing and Using Node.js on Windows

Have you ever wondered how massive modern platforms like Netflix, PayPal, and LinkedIn handle millions of users simultaneously without crashing? The secret weapon behind much of the modern web is Node.js. Traditionally, JavaScript—the language that makes websites interactive—could only run inside a web browser like Chrome or Edge. Node.js changed the game by freeing JavaScript from the browser, allowing it to run directly on your computer. This means you can use it to build backend servers, automate boring computer tasks, or run powerful development tools. If you are intimidated by coding, don't worry. This guide will take you from zero to running your very first Node.js program on Windows, step-by-step. Prerequisites Before we begin, you only need two things: A computer running Windows 10 or 11. An active internet connection to download the installer. No prior coding experience or command-line knowledge is required! Step-by-Step Instructions Download the Node.js Installer First, we need to grab the official installation file. Open your web browser and go to the official website: nodejs.org. You will see two primary options to download. Always choose the LTS (Long Term Support) version. The LTS version is heavily tested, stable, and less likely to give you unexpected errors. Click the Windows Installer button to download the .msi file to your computer. Run the Setup Wizard Once the download finishes, navigate to your Downloads folder and double-click the file to open the setup wizard. Click Next on the welcome screen. Accept the license agreement and click Next. Leave the default installation folder as it is (C:\Program Files\nodejs) and click Next. On the "Custom Setup" screen, leave everything at its default and click Next. Important Step: You will see a checkbox that asks to "Automatically install the necessary tools." Leave this unchecked for now to keep your setup simple and fast. Click Next. Finally, click Install. If Windows asks for permission to make change
