Developer Builds React-Based Fuel Cost Calculator Using useState and JSON Pricing

·3 views

A developer has shared the technical breakdown of a mini fuel calculation web app built with React, designed to simulate a gas station experience. Fuel prices for seven types — including gasoline grades, diesel, LPG, and electricity — are stored in a JSON file for centralized management. The app features two main components, Header and Content, where users select a fuel type from a dropdown, enter a quantity, and click a button to generate a receipt-style cost summary. The CalcFuel function multiplies the stored unit price by the user-entered amount, with React's useState hook enabling dynamic rendering of results in the UI. The project's source code has been made publicly available on GitHub.

Experts Argue Teen Social Media Bans Fail to Address Root Causes

A piece published by MIT Press argues that outright bans on social media for teenagers are misguided policy. The article contends that such bans fail to tackle the underlying issues driving harm among young users. Rather than restricting access, the authors suggest more nuanced approaches are needed to protect teen wellbeing online. The discussion has drawn attention on Hacker News, where readers are debating the effectiveness of age-based platform restrictions.

Developer Uses Parallel AI Agents to Document a Debt-Ridden, Undocumented Codebase

A software developer shared how they tackled the challenge of documenting a heavily indebted, undocumented codebase that had grown from a poorly built MVP. The core problems included duplicated business logic, obsolete database columns, and implicit dependencies that confused AI coding assistants. Drawing on a Meta research article, the developer implemented a parallel-agents workflow where multiple AI agents analyze the codebase simultaneously across defined business domains such as orders, payments, and billing. Each agent follows a structured 'compass' approach, extracting key files, non-obvious patterns, quick commands, and cross-references rather than generating generic filler documentation. The goal is to make implicit architecture explicit, giving future AI development agents accurate context and constraints before they begin making changes.

Developer builds Laravel-inspired fullstack framework for Bun runtime

A developer has created Guren, a fullstack application framework for the Bun runtime, designed to eliminate repetitive architectural decisions on new projects. While Bun already supports fast APIs through frameworks like Hono and Elysia, it lacks opinionated structure for fullstack apps covering authentication, database migrations, background jobs, and frontend data flow. Bun's built-in fullstack dev server, introduced in version 1.2.3, handles bundling and HMR but explicitly leaves out SSR, auto-discovered routes, and broader application architecture. Guren aims to fill that gap by providing a Laravel-shaped convention layer on top of Bun's primitives, so developers can skip re-deciding project structure, database libraries, and frontend integration each time. The framework targets common fullstack needs such as typed API clients, persistent sessions, OAuth, email verification, and deployment strategy.

Developer builds C library to render histograms directly in the terminal

A developer built a lightweight C plotting library called plt.c to visualize histograms inside the terminal using Unicode block characters. The project was motivated by a desire to inspect random number distributions without relying on external tools like Python's matplotlib. The library works by bucketing float data into columns, scaling the Y-axis relative to the maximum bucket count, and mapping values to Unicode block characters for sub-row precision. It also handles X-axis scaling by normalizing the data range to fit the configured number of columns. The final library exposes a single function, plt_hist, and was tested with up to 10,000 samples across uniform and normal distributions.
