Developer Builds Privacy-First Personality Quiz That Runs Entirely in the Browser

·1 views

A developer has created Soul Color Test, a personality quiz built with Next.js and TypeScript that processes all data locally without a backend. The quiz offers two modes: a 7-question quick version and a 16-question deep dive, both scoring results entirely within the browser. User progress is stored locally, requiring no account creation or server-side API calls. The project is deployed as a static export on Cloudflare Pages, with static result pages enabling sharing and search discovery. Designed for entertainment and self-reflection rather than diagnosis, the developer is seeking community feedback on quiz flow, result clarity, and mobile experience.

Developer Builds App to Help People Find Menstrual Products in Public Spaces

A developer created PadForward, a community-powered platform that helps people locate or donate menstrual products at public locations such as train stations, universities, and community centres. The idea came after the developer was caught off guard by an unexpected period while near a train station that offered no access to sanitary products. The app allows users to find nearby pad drop-off points without needing an account or having to ask strangers directly. Donors can also use the platform to identify which locations are most in need of supplies, reducing the guesswork around where to contribute. PadForward was built as a Weekend Challenge submission and is currently available as a live demo on Vercel with its code published on GitHub.

DIY Car Diagnostics With a $18 ESP32 vs. a $180 Dealership Fee

A hobbyist diagnosed an intermittent warning light on their car using an ESP32-C3 microcontroller and a CAN bus transceiver costing under $20 in total, completing the task in eleven seconds. A dealership had quoted $180 simply to plug in a diagnostic tool and schedule the appointment for the following week. Modern vehicles run on a Controller Area Network (CAN bus), a two-wire communication system developed by Bosch in the 1980s, over which dozens of onboard computers continuously broadcast data. While newer vehicles use gateway modules that restrict what third-party tools can read via the OBD-II port, the underlying diagnostic protocols remain accessible to informed users. The author argues that dealership diagnostic pricing reflects control over tooling and software licenses rather than genuine technical complexity.

Developer builds CLI tool to sort Dependabot PRs, draws firm limits on automation

A software developer built an open-source CLI tool called dep-triage to automatically categorize open Dependabot pull requests on GitHub into five action buckets — including auto-merge, escalate, close, rebase, and skip — based on a policy file stored in the repository. The tool uses fully deterministic logic with no AI involvement, and dry-run mode is enabled by default to prevent unintended changes. A strict scope check ensures only PRs that exclusively modify dependency manifests or lockfiles are eligible for auto-merge, while any PR touching source code is automatically excluded. To guard against race conditions, the tool re-fetches the latest commit SHA and CI status immediately before applying any merge action, aborting if anything has changed since the initial triage. Testing against a real repository with 11 open PRs revealed edge cases that unit tests missed, including GitHub's combined-status API returning identical responses for both pending CI and absent CI checks.
