Developer Releases Free Open-Source Equation Editor Built for CBT Platforms

·1 views

A developer has launched CBT Editor, a free and open-source equation editor designed specifically for computer-based testing platforms. The tool was created after its author struggled to find a lightweight, unified solution for writing math and chemistry questions in online exam systems. CBT Editor combines multiple existing open-source libraries into a single interface that supports mathematical expressions, chemistry notation, fractions, superscripts, subscripts, and scientific symbols. It is intended for developers, schools, and educational platforms that need to integrate technical question formatting without assembling multiple tools manually. The project is publicly available with a live demo, and the developer is inviting contributions, feedback, and issue reports from the community.

How AI Tools Like Hugging Face and Streamlit Can Turn Plain English Into SQL

Developers can now build Text-to-SQL applications that convert plain English questions into executable SQL queries using large language models from Hugging Face and a Streamlit front end. The approach allows non-technical users — such as sales managers, doctors, or e-commerce analysts — to retrieve database information without writing any SQL code. A T5-based model processes the user's natural language input and generates a corresponding SQL query, which is then run against a database and displayed as a result. However, experts caution that AI-generated SQL must always be validated before execution, and database permissions should be restricted to read-only to prevent harmful operations. Open-source projects such as Vanna AI, SQLCoder, and LangChain's SQL agents already demonstrate production-ready implementations of this technology.

Solo Developer Pivots Social App into Bangla-First AI Platform RexiO

A developer originally building a small social platform called spritex-social ended up creating an AI startup after adding a support chatbot powered by Google's Gemini API. The chatbot, built using a Retrieval-Augmented Generation system, gradually consumed more of his attention than the social app itself. Recognizing the shift, he abandoned the original project and began building RexiO, a Bangla-first AI platform featuring its own orchestration layer, intent classifier, over 30 tools, and fine-tuned models trained on Colab GPUs. RexiO was developed entirely solo and launched publicly on July 10, 2026, positioning itself as an AI solution designed specifically for Bangladeshi users beyond simple Bangla text output.

GhostLine Browser Platform Shifts Focus From Features to Stability

GhostLine is a privacy-first, browser-based communication platform designed to enable secure messaging, video calls, and file sharing without requiring user accounts. The platform currently supports end-to-end encrypted messaging, real-time room-based communication via WebRTC, secure file sharing, and shared notes, all built on a lightweight Go and vanilla JavaScript stack. The developer reports that the core communication experience is now fully functional end-to-end. Recent development efforts have shifted away from adding new features toward improving startup flow, simplifying the UI, and reducing technical debt. The project is approaching its next major milestone, with the developer focused on making the platform polished and dependable for everyday use.
