Sri Lanka secured a hard-fought draw against India in a Test match played in Colombo. Batsman Dinusha anchored the innings with a defiant unbeaten 133, receiving crucial support from the lower order. India managed to take only three wickets on the fifth and final day despite persistent efforts. The result denied India a victory they had appeared well-placed to achieve heading into the last day.
A newly published academic thesis explores how artificial intelligence tools are reshaping education, from adaptive tutoring systems that tailor content to individual learners to automated essay grading powered by natural language processing. The study argues that AI will not replace teachers but can free them from repetitive tasks, allowing them to focus on mentorship, motivation, and human connection. Evidence reviewed in the thesis shows measurable gains in student performance, particularly in mathematics, though researchers caution that adaptive systems track pace rather than deeper understanding or student motivation. The thesis also raises serious concerns about data privacy, algorithmic bias, and the risk that well-intentioned tools may widen existing inequalities rather than close them. Ultimately, the authors contend that whether AI serves all students or only a privileged few depends entirely on the policy and design choices made by educators, developers, and policymakers today.
Flash floods on Nepal's Bhotekoshi River have killed at least 270 people, according to Nepal Police on Thursday. The death toll climbed after 93 additional bodies were recovered in the latest update. Thousands of people remain missing in the aftermath of the disaster. Rescue operations are currently underway to locate survivors and the missing.
A 13-year study conducted in Hawaii has revealed alarming levels of plastic ingestion in pilot whales. Researchers discovered tens of thousands of synthetic debris fragments, including discarded fishing nets and plastic bags, lodged inside the stomachs of examined whales. One individual whale was found to have ingested 35,543 pieces of plastic. Scientists warn that such pollution poses serious long-term health risks to these marine mammals. The findings highlight the urgent need for stronger measures to address ocean plastic waste.
Developers using LlamaIndex typically need two separate backends — a vector store and a graph database — to support both VectorStoreIndex and PropertyGraphIndex. SynapCores is a single engine that now supports both index types through two independently published LlamaIndex integration packages on PyPI. The vector store implements the full BasePydanticVectorStore interface, including all 12 metadata filter operators and async support, while the graph store implements the full PropertyGraphStore interface with both structured and vector query capabilities. Both index types connect to the same SynapCores instance via a single URI, eliminating the need for cross-service synchronization. The integration is backed by 48 automated tests run against a live engine via Docker Compose, with source code and notebooks available on GitHub.
A developer has released a production-ready gift redemption system as a free resource for the developer community, published on GitHub under the Vlox project. The system is built using Node.js and MongoDB, featuring authentication middleware, input validation, and atomic database transactions to ensure data integrity. A key feature grants users a character boost of up to 100, capped at a 4,000-character maximum, with MongoDB's atomic operations preventing duplicate claims during concurrent requests. The code handles both gift and user record updates within a single transaction, rolling back all changes if either operation fails. The project is open-source and available for developers to integrate directly into their own applications.
A developer published halloween.js, a lightweight library that adds Halloween-themed visual effects to websites using CSS classes on the document body. Rather than an imperative API, the library uses a MutationObserver to watch for class changes, making it compatible with CMS platforms and page builders where JavaScript execution order cannot be controlled. When an effect class is removed, the library immediately tears down the animation instead of waiting for the current cycle to finish, preventing effects from lingering after being explicitly disabled. The library also supports a configurable season window, with start and end dates sourced from data attributes, script query parameters, or hardcoded defaults — re-evaluated on every sync so runtime CMS changes take effect without a page reload. The developer shared these decisions to highlight how real-world usage in uncontrolled environments surfaces edge cases that seem simple at first glance.
Robotic Process Automation (RPA) is an AI and machine learning-powered software technology designed to handle high-volume, repetitive digital tasks such as data entry, record maintenance, and transaction processing — not physical robots. RPA follows deterministic logic, meaning it executes tasks with consistency but lacks complex human reasoning. The RPA development lifecycle spans four key phases: planning, development, deployment and testing, and ongoing support and maintenance. Companies are increasingly adopting RPA for its ability to reduce operational costs by up to 65%, eliminate human error, and enable round-the-clock processing without downtime. Growing industry interest in RPA reflects its practical value in streamlining backend workflows and improving customer response times.
Devastating flash floods have claimed at least 359 lives across Nepal, according to government officials. The floodwaters swept through a major district market area before surging downstream with destructive force. Homes, livestock, public buildings, and infrastructure were all consumed in the deluge. Search and rescue operations are ongoing as authorities work to locate survivors still missing in the aftermath.
Bitcoin Lightning network node operators have received an emergency security warning following the discovery of critical bugs. The vulnerabilities were identified through AI-assisted work on Bitcoin code. Developers have chosen to withhold technical details for two weeks to allow operators sufficient time to apply fixes. This marks the second Lightning network security emergency this month linked to AI involvement in Bitcoin development.
A 12-year-old developer named Harun has amassed nearly 1,000 followers on Dev.to while building an AI mentorship tool called KODA on a budget Android phone. To mark the milestone, he has announced a seven-day global coding challenge open to developers worldwide. Participants are tasked with building a single-page website for a niche audience, with the requirement that at least half the code is generated using KODA. Winners will receive permanent in-app rewards including a crown theme, doubled memory, and a Pro Sensei Mode. Harun credited community members for helping him resolve a backend database error in his Supabase project during the event's lead-up.

A developer on DEV Community shared how a user spent an entire day re-confirming an already-verified email address because the API kept returning a misleading error message. The root cause was a single error response covering two unrelated conditions: an unverified email and a restricted preview API key. The user had copied a limited preview key into his workflow at signup, and verifying his email never upgraded that key's permissions. The fix involved both splitting the error messages to identify the correct problem and automatically upgrading preview keys the moment email verification is completed. The issue went undetected for months since the API returned a clean 403 response with no exceptions or alerts, and was only discovered after the user tracked down the developer on LinkedIn when the support email address turned out to be non-existent.
