Developer Builds Client-Side Binary-Decimal Converter with Step-by-Step Math Breakdown

·1 views

A developer shared a tutorial on DEV Community detailing how to build a fully client-side binary-to-decimal converter using vanilla JavaScript. The tool was created to address privacy concerns when auditing proprietary code or network configurations, as many existing converters rely on server-side processing. It displays an interactive, step-by-step mathematical derivation for each conversion, supporting both binary-to-decimal and decimal-to-binary directions. The implementation handles inputs up to 31 binary bits to avoid browser performance issues and stay within safe integer limits. The project was built with AI-assisted development and is designed to be easily integrated into a developer's personal toolbox.

AI-Powered Prototyping Can Cut Software Planning Time from Hours to Minutes

A software developer argues that most teams default to production-grade planning even when a lighter prototype-first approach would be more efficient. Speaking at the Agentic Builders Collective in Singapore, the author found that AI-assisted production planning still took up to three hours and often caught errors too late. The core insight is that prototype-grade software deserves prototype-grade planning, and generative AI has made rapid prototyping far cheaper and faster than before. The proposed workflow involves writing brief requirements, running an AI agent to generate a product requirements document, building a quick prototype to learn from, and only then planning the production version. The author cautions that prototypes do not surface scaling limits, security concerns, or compliance obligations, which is why the two planning grades must remain distinct.

Google Workspace CLI Lets Developers Automate Drive, Gmail and More via Command Line

Google has released an open-source command-line tool called Google Workspace CLI (gws), announced by Addy Osmani in early 2026. The Rust-powered tool provides unified command-line access to Google Workspace services including Drive, Gmail, Calendar, Sheets, Docs, and Chat through a single interface. It builds commands dynamically using Google's Discovery Service, eliminating the need for separate SDKs, custom OAuth flows, or manual API scripts. The CLI supports JSON output, pagination helpers, dry-run mode, and agent integrations for tools like Claude Code, Cursor, and Gemini CLI. It requires Node.js 18 or later and can be installed via npm, Homebrew, Nix, or directly from GitHub Releases.

Laid-off developers build open source AI CEO after being replaced by AI

A group of software developers who were fired by their CEO to cut costs in favor of AI tools have responded by building an open source AI CEO called OpenExecutive. The project is hosted on GitHub under SenteLabsAI and appears to be a direct rebuttal to the decision that cost them their jobs. The move highlights growing tensions between tech workers and executives who are replacing human talent with artificial intelligence. The project has gained early attention on Hacker News, though it remains in its initial stages with limited community engagement so far.
