Show HN: Daily-updated database of malicious browser extensions Hey HN, I built an automated system that tracks malicious Chrome/Edge extensions daily. The database updates automatically by monitoring chrome-stats for removed extensions and scanning security blogs. Currently tracking 1000+ known malicious extensions with extension IDs, names, and dates. I'm working on detection tools (GUI + CLI) to scan locally installed extensions against this database, but wanted to share the raw data first since maintained threat intelligence lists like this are hard to find. The automation runs 24/7 and pushes updates to GitHub. Free to use for research, integration into security tools, or whatever you need. Happy to answer questions about the scraping approach or data collection methods. https://ift.tt/F0bgy8c February 6, 2026 at 11:34PM

Show HN: A password system with no database, no sync, and nothing to breach Hi HN, Bastion Enclave is an experiment in removing centralized trust from password management by eliminating server-side state entirely. Instead of storing an encrypted vault or syncing secrets through a backend, Bastion computes credentials deterministically on-the-fly using explicit cryptographic inputs. Given the same master entropy, service name, username, and version counter, the same password is reproduced across platforms. There is no account system, no database, and no persistent server storage — the server serves static code only. Password generation uses domain-separated salts and PBKDF2-HMAC-SHA512 (210k iterations) to produce a byte stream, followed by unbiased rejection sampling to avoid modulo bias when mapping to character sets. Nothing is stored; passwords are derived when needed and discarded immediately after use. When users choose to persist data locally (vault state, notes, file keys), encr...

Show HN: BPU – Reliable ESP32 Serial Streaming with Cobs and CRC Hi HN, I’d like to share BPU, a high-speed serial streaming engine I built using ESP32 devices. BPU is a small experimental project that demonstrates a reliable data pipeline: ESP32-WROOM → ESP32-S3 → PC Data is transmitted over UART at 921600 baud, framed with COBS, validated with CRC16, and visualized in real time on the PC using Python and matplotlib. The main goal of this project was to stress-test embedded streaming reliability under high throughput and noisy conditions. Features: - COBS framing (0x00 delimited packets) - CRC16-CCITT integrity validation - Sequence number checking - High-rate draw point generator - Real-time visualization - Throughput and error statistics The system continuously sends drawing data from the WROOM, forwards it through the S3 as a USB bridge, and renders it live on the PC. This helped me experiment with: - Packet loss detection - Latency behavior - Error recovery - Buffer stability - Su...

Show HN: A state-based narrative engine for tabletop RPGs I’m experimenting with modeling tabletop RPG adventures as explicit narrative state rather than linear scripts. Everdice is a small web app that tracks conditional scenes and choice-driven state transitions to preserve continuity across long or asynchronous campaigns. The core contribution is explicit narrative state and causality, not automation. The real heavy lifting is happening in the DM Toolkit/Run Sessions area, and integrates CAML (Canonical Adventure Modeling Language) that I developed to transport narratives among any number of platforms. I also built the npm CAML-lint to check validity of narratives. I'm interested in your thoughts. https://ift.tt/6TQj5I7 https://ift.tt/NnU8Qjx February 6, 2026 at 05:55AM

Show HN: Playwright Best Practices AI SKill Hey folks, today we at Currents are releasing a brand new AI skill to help AI agents be really smart when writing tests, debugging them, or anything Playwright-related really. This is a very comprehensive skill, covering everyday topics like fixing flakiness, authentication, or writing fixtures... to more niche topics like testing Electron apps, PWAs, iFrames and so forth. It should make your agent much better at writing, debugging and maintaining Playwright code. for whoever didn't learn about skills yet, it's a new powerful feature that allows you to make the AI agents in your editor/cli (Cursor, Claude, Antigravity, etc) experts in some domain and better at performing specific tasks. (See https://ift.tt/8M6kKQb ) You can install it by running: npx skills add https://ift.tt/TVPtGyS... The skill is open-source and available under MIT license at https://ift.tt/TVPtGyS... -> check out the repo for full documentation and understandin...
