How to Self-Host Neko Virtual Browser on Linux Using Docker and Traefik

·3 views

Neko is an open-source platform that runs a virtual browser inside Docker and streams the session to multiple users simultaneously via WebRTC with synchronized audio and video. The setup uses Docker Compose with Traefik as a reverse proxy to handle automatic HTTPS certificate provisioning through Let's Encrypt. Firefox profile data is stored persistently on the host, and shared memory is set to 2GB to prevent rendering crashes. Admins can control input handoff between connected users, while participants join using a separate user password via a web interface. UDP ports in the 52000–52100 range must be open for WebRTC media traffic to flow correctly.

Developer Builds Arcade Game to Visualize How Vector Databases Work

A developer has created a retro-style arcade game called Vector Strike to help users understand how vector databases such as Pinecone, Milvus, and Qdrant perform semantic search. The game lets players act as a vector database administrator, adjusting settings like similarity thresholds, embedding dimensions, and indexing methods to defend index nodes. Each in-game mechanic directly mirrors a real production concept, such as how reducing embedding dimensions causes semantic overlap and false matches. Players can also toggle between brute-force flat scanning and HNSW graph-based indexing to see how proximity graphs speed up nearest-neighbor search. The project aims to make abstract concepts like cosine similarity and high-dimensional embeddings more intuitive through interactive, visual gameplay.

Developer Rebuilds AES Encryption Tool With Full Browser-Side Processing

A developer has relaunched aesencryption.net, a free online tool that performs AES encryption and decryption — supporting 128, 192, and 256-bit keys — entirely within the user's browser, ensuring no data leaves the page. The rebuild focused on maintaining byte-level compatibility with common server-side AES libraries across multiple languages. To support this, the site includes copy-paste code equivalents in PHP, Java, Python, Go, Rust, Kotlin, and JavaScript. The tool handles key technical details such as encryption mode, initialization vectors, padding, and Base64 output. The developer has made the tool publicly available at no cost and is actively seeking community feedback on the cryptographic design choices.

How to Self-Host Plausible Analytics with Docker, Nginx, and Let's Encrypt

Plausible Analytics is an open-source, privacy-focused web analytics platform that collects traffic data without using cookies or personal identifiers, serving as an alternative to Google Analytics. A step-by-step deployment guide covers setting up Plausible Community Edition using Docker Compose, with PostgreSQL and ClickHouse handling the underlying databases. Nginx is configured as a reverse proxy to route public traffic to the locally bound application, and a free Let's Encrypt TLS certificate is issued via Certbot to secure the connection over HTTPS. Once deployed, users register an admin account, add their website, and embed a lightweight JavaScript snippet to begin capturing live traffic statistics. The setup also supports multi-site tracking, scheduled email or Slack reports, and a Stats API for custom data exports.
