Developer Builds Zero-Cost AI Habit App Using Groq, Supabase, and React

·5 views

A software developer shared on DEV Community how they built a personal AI accountability app after repeatedly failing to stick with existing habit trackers. The app centers on a single daily 'Prime Directive' task, an urge-management timer with breathing exercises, and an AI coach powered by Groq's Llama 3.1 model that tracks user patterns over time. The tech stack includes React, Supabase, Vercel, and Framer Motion, with the developer reporting a total monthly running cost of zero dollars thanks to free tiers. The app is deployed as a progressive web app at zenith-fortify.vercel.app and monetized through Gumroad premium subscriptions. The developer, describing it as their first real project, is actively seeking user feedback and plans to add native iOS and Android support along with an accountability partner feature.

Azure Cosmos DB vNext Emulator Gains AI Agent Support via CLI and Skills

Microsoft's Azure Cosmos DB vNext emulator now supports AI coding agents such as GitHub Copilot CLI, Codex, and Claude Code through its built-in Cosmos DB Shell, an open-source CLI that runs inside the emulator container. The CLI's command-based structure makes it well-suited for agent workflows, allowing agents to discover operations, execute commands non-interactively, and act on returned results. A dedicated Agent Skill called cosmosdb-emulator-vnext packages task-specific guidance to help agents inspect resources, create databases and containers, load test data, and run queries. In a demonstration, a developer prompted GitHub Copilot CLI to set up a local emulator with synthetic multi-tenant order data, and the agent autonomously created a partitioned database with 12 realistic orders spanning multiple statuses. The integration aims to reduce manual setup work, letting developers describe desired outcomes rather than writing out individual shell commands.

Software Engineer Rebuilds Career After Burnout, Illness, and Layoff

Cesar Aguirre, a software engineer with over 10 years of experience, is publicly sharing his journey of career rebuilding after facing serious personal and professional setbacks. He experienced illness, burnout, and a layoff, all of which significantly disrupted his career path. Aguirre has turned to writing as a form of therapy and is also working on a book trilogy as part of his recovery and reinvention process. He opened an Ask Me Anything (AMA) session on DEV Community on July 20, inviting others to engage with his story. The post sparked discussion around mental health, resilience, and career challenges in the tech industry.

Claude for Chrome and Tap MCP Servers Offer Complementary Browser Automation Roles

Claude for Chrome is a browser assistant that uses live AI reasoning to handle one-off tasks, exploration, and judgment-dependent workflows inside a user's logged-in Chrome session. However, because it re-reasons through every task on each run, repeated workflows consume model tokens and require the machine to remain active. Tap, a separate MCP server running alongside Claude for Chrome in the same Claude Code session, addresses this by compiling a completed browser flow into a deterministic .tap.json plan. Once compiled, the plan replays the workflow at zero LLM token cost on a local schedule, without needing further AI inference. The two tools are designed to complement each other: Claude for Chrome handles novel or adaptive tasks, while Tap handles the repetitive execution of already-solved workflows.

How systemd-run Makes Linux cgroup Resource Limits Simple and Instant

Linux developers dealing with runaway processes can use systemd-run to apply memory and CPU limits without editing service files or rebooting. The command wraps the cgroups interface managed by systemd, letting users set constraints like a 256MB memory cap directly at runtime. For persistent limits, service unit files support directives such as MemoryMax and CPUQuota to enforce hard resource ceilings on long-running services. The MemoryHigh directive offers a softer threshold that triggers kernel memory reclamation before a hard limit is reached. Developers can inspect live cgroup data via the /sys/fs/cgroup filesystem, making it easier to monitor and debug resource usage without modifying system configuration.
