PoE Lighting Market Hits $2.1B as Ethernet Cables Begin Replacing Power Wires in Buildings

·1 views

Power over Ethernet (PoE) lighting is gaining commercial traction, with the global market reaching $2.1 billion in 2026 and projected to exceed $4.3 billion by 2032 at a 12.59% CAGR, according to a 360iResearch report. A Grade-A office tower project in Shenzhen illustrated the shift, using standard Cat6a Ethernet cables to deliver both power and data to every LED luminaire, eliminating traditional 220V AC mains wiring. The approach reportedly cut total wiring costs by around 30% and shortened renovation timelines by 15 days by merging electrical and IT network installations into a single cable run. The IEEE 802.3bt standard now enables up to 90W per port, sufficient for most commercial LED fixtures, while giving each luminaire a unique IP address for full network-based control. The transition is fundamentally redesigning LED drivers, shifting their input from high-voltage AC to 48V DC and adding built-in network communication, effectively turning a power component into an IT device.

Cursor Launches Origin, a Git Hosting Platform Built for AI-Driven Development

Cursor has announced Origin, its own git hosting and code collaboration platform designed for teams and AI agents. The product covers repository hosting, code review, and collaboration workflows, targeting a gap in the AI coding pipeline that Cursor previously left to services like GitHub and GitLab. Origin is reported to be connected to Cursor's earlier acquisition of Graphite, which specialised in high-volume pull request workflows. The platform is described as built for the speed at which AI agents generate and push code, which Cursor argues exceeds what traditional forges were designed to handle. A public waitlist is now open at cursor.com/origin, with a general release expected this fall; pricing and full documentation have not yet been published.

Hub Sites Don't Fix Microsoft 365 Cross-Team Search — Here's What Actually Does

A common frustration in Microsoft 365 is that files shared across Teams become hard to find, and adding a hub site is often the first attempted fix. However, hub sites only unify navigation and scope search — they do not grant users permission to access content they are not already members of. Adding everyone to every Team restores search visibility but destroys confidentiality boundaries and floods channels with noise, making it an unacceptable trade-off for sensitive projects. The real solution is an information architecture decision: separating active work in member-gated Teams from completed work moved to broadly readable sites, surfaced through a hub. This three-tier approach — active work, a read tier for closed projects, and an exceptions flow via SharePoint access requests — addresses discovery without compromising security.

Developer releases edfcore, a zero-dependency TypeScript library for parsing EDF biosignal files

A developer has released edfcore, an open-source TypeScript library designed to parse EDF-family biosignal recordings — including EEG, ECG, and sleep-study data — without any external dependencies. The library allows developers to work with biosignal data directly in JavaScript and TypeScript environments such as browsers, Node.js pipelines, and Electron applications. Building the parser revealed several non-obvious complexities in the EDF format, including per-signal sampling rates, annotation data embedded as signal channels, and 24-bit sample values in BDF files that require manual byte reconstruction. The developer noted that subtle parsing errors are especially difficult to detect because they can produce plausible-looking waveforms rather than obvious failures. A companion CLI tool called edf2csv is also available for converting EDF and BDF recordings to CSV format; both projects are MIT licensed and published on GitHub and NPM.

Vector Databases Explained: How They Give AI Apps Memory and Context

Vector databases have emerged as critical infrastructure for modern AI applications, solving a key limitation of large language models — their lack of long-term memory or access to private data. Unlike traditional databases that rely on exact keyword matches, vector databases store high-dimensional numerical embeddings that capture semantic meaning, allowing searches for conceptually similar content even when exact words differ. An embedding model converts unstructured data — text, images, or audio — into arrays of floating-point numbers, where related concepts cluster geometrically close together in multi-dimensional space. These databases power use cases such as Retrieval-Augmented Generation (RAG), which reduces AI hallucinations by fetching relevant context before querying a language model. Popular options range from dedicated services like Pinecone and Weaviate to PostgreSQL extensions like pgvector and embedded solutions like LanceDB, each suited to different scalability and infrastructure needs.
