Developer builds interactive puzzle cube using only CSS

·1 views

A developer created a 3D point-and-click puzzle game powered entirely by CSS, without using JavaScript. The project, showcased on CodePen, began as an experiment in rendering 3D objects with CSS. The game uses CSS variables and animations to manage state, handle inputs, and sequence the puzzle logic. The developer's article explains the key techniques, such as constructing a 3D cube and reading input values directly in CSS.

Spreadsheet automation error shows identical totals despite missing data

An AI agent simulating office automation found a flaw in a common method for merging monthly sales reports from twelve branches. When merging spreadsheet files by column position, a single branch with a different column order caused data misalignment. This resulted in a final report where the overall sales total was correct, but one branch's sales were attributed to a non-existent branch. The report highlights that matching totals and row counts are insufficient to guarantee data integrity and recommends validating merges by column name instead of position.

Open-source AI tool translates menus offline for small restaurants

A developer created an open-source menu translator called DineLingo for small restaurants with tourist customers. The tool translates dish descriptions from Hinglish into tourist-ready formats with allergen and vegetarian flags. It uses Google's Gemma AI model via Hugging Face and operates entirely offline to keep recipe data private. Restaurants pay a one-time fee of approximately $6 for translating up to 30 dishes instead of subscription-based services. The project was submitted for the Hacktoberfest Open-Source AI Challenge.

Open reference architecture improves integrity of radar tank gauge monitoring

An open reference architecture has been published to address faulty gauge readings at a fuel terminal in Pakistan. The system tackles flatlined and swapped readings from radar tank gauges on Modbus loops, which are currently undetectable until inventory discrepancies arise. The design proposes installing signal boosters within explosion-proof junction boxes to monitor loop health and improve data quality. An ontology service and integrity monitor run on the operator's existing server, creating a clearer inventory picture without replacing the original gauging host. The entire architecture, including its object model, is freely available under a CC BY 4.0 license.

Durable Sessions Added to Claude Agent SDK for Crash-Resistant AI Tasks

The Dapr Agents project has released a durable sessions feature for its Claude Agent SDK. This update allows AI agents built with Claude to survive process crashes and resume tasks from where they left off, using a session journal. It also enables human-in-the-loop approvals that persist through system restarts and deployments. The functionality is now available and can be integrated via a Python package. Similar durable session support is also available for LangChain Deep Agents through a related adapter.
