Show HN: Hc: an agentless, multi-tenant shell history sink This project is a tool for engineers who live in the terminal and are tired of losing their command history to ephemeral servers or fragmented `.bash_history` files. If you’re jumping between dozens of boxes, many of which might be destroyed an hour later, your "local memory" (the history file) is essentially useless. This tool builds a centralized, permanent brain for your shell activity, ensuring that a complex one-liner you crafted months ago remains accessible even if the server it ran on is long gone. The core mechanism wants to be a "zero-touch" capture that happens at the connection gateway level. Instead of installing logging agents or scripts on every target machine, the tool reconstructs your terminal sessions from raw recording files generated by the proxy you use to connect. This "in-flight" capture means you get a high-fidelity log of every keystroke and output without ever having to touch the configuration of the remote host. It’s a passive way to build a personal knowledge base while you work. To handle the reality of context-switching, the tool is designed with a "multi-tenant" architecture. For an individual engineer, this isn't about managing different users, but about isolating project contexts. It automatically categorizes history based on the specific organization or project tags defined at the gateway. This keeps your work for different clients or personal side-projects in separate buckets, so you don't have to wade through unrelated noise when you're looking for a specific solution. In true nerd fashion, the search interface stays exactly where you want it: in the command line. There is no bloated web UI to slow you down. The tool turns your entire professional history into a searchable, greppable database accessible directly from your terminal.

Show HN: BGP Scout – BGP Network Browser https://ift.tt/13APl6o

Show HN: BGP Scout – BGP Network Browser Hi HN, When working with BGP data, I kept running into the same friction: it’s easy to get raw data, but surprisingly hard to browse networks over time — especially by when they appeared, where they operate, and what they actually look like at a glance. I built a small tool, bgpscout.io, to scratch that itch. It lets you: Browse ASNs by registration date and geography See where a given network appears to have presence View commonly scattered public data about an ASN in one place Save searches to track when new networks matching certain criteria appear All of this data is public already; the goal was to make exploration faster and less painful. I haven’t invested heavily in expanding it yet. Before doing so, I’m curious: Is this solving a real problem for you? What would make something like this actually useful in day-to-day work? Feedback is welcome. https://bgpscout.io/ January 15, 2026 at 09:52PM

Show HN: The viral speed read at 900wpm app This rapid serial visual processing went viral the last few days. I built this app a few weeks ago to take advantage of the auto-playing videos on social media. Now you can beam text right into your followers eye sockets! https://wordblip.com January 16, 2026 at 02:20AM

Show HN: Reversing YouTube’s “Most Replayed” Graph https://ift.tt/ZuW72BM

Show HN: Reversing YouTube’s “Most Replayed” Graph Hi HN, I recently noticed a recurring visual artifact in the "Most Replayed" heatmap on the YouTube player. The highest peaks were always surrounded by two dips. I got curious about why they were there, so I decided to reverse engineer the feature to find out. This post documents the deep dive. It starts with a system design recreation, reverse engineering the rendering code, and ends with the mathematics. This is also my first attempt at writing an interactive article. I would love to hear your thoughts on the investigation and the format. https://ift.tt/rHMEkVD January 15, 2026 at 11:06PM

Show HN: Liberty – Hardware-bound secret manager (no more .env files) https://ift.tt/PS2i8xb

Show HN: Liberty – Hardware-bound secret manager (no more .env files) I got tired of: - .env files committed to Git (seen it happen 100+ times) - API keys shared in Slack - Wondering who has access to what secrets So I built Liberty - a CLI tool that replaces .env files with hardware-bound encryption. How it works: $ pip install liberty-secrets $ liberty add DATABASE_URL postgresql://... $ liberty add STRIPE_KEY sk-... $ liberty exec npm start Secrets are encrypted with a key derived from your machine's hardware (CPU ID + machine ID + disk serial). If someone steals your .liberty vault file, it's useless on their machine. Features: - Hardware-bound AES-256-GCM encryption - Complete audit trail (compliance-ready) - Works offline (no servers, no accounts) - Global vault (~/.liberty/ works from any directory) - MIT licensed, free for individual use GitLab: https://ift.tt/rt1aD8m PyPI: https://ift.tt/buJqeDr Team features (secret sharing) coming soon as paid tier. Feedback welcome! January 14, 2026 at 02:49AM

Show HN: IMSAI/Altair inspired microcomputer with web emulator https://ift.tt/JBiY2Nx

Show HN: IMSAI/Altair inspired microcomputer with web emulator I designed and built a physical replica of a 1970s-style front panel microcomputer with 25+ toggle switches, 16 LEDs, and an LCD display. The brain is a Raspberry Pi Pico running an Intel 8080 CPU emulator. The main twist: I decided to see how far I could get using Claude Code for the firmware. That and the web emulator were written almost entirely using Claude Code (Opus 4.5). I've kept the full prompt history here: https://ift.tt/UxMAJSP.... It was able to create the emulator in just a few prompts! It really surprised me that it was able to make a WebAssembly version from the same code (compiled with emscripten) and get the physical layout of the panel from a given photo. It also created some simple working examples using 8086 instructions! Repository: https://ift.tt/D5q3Ffm https://gzalo.github.io/microcomputer/ January 14, 2026 at 10:57PM

Show HN: OSS AI agent that indexes and searches the Epstein files https://ift.tt/i7Vx95f

Show HN: OSS AI agent that indexes and searches the Epstein files Hi HN, I built an open-source AI agent that has already indexed and can search the entire Epstein files, roughly 100M words of publicly released documents. The goal was simple: make a large, messy corpus of PDFs and text files immediately searchable in a precise way, without relying on keyword search or bloated prompts. What it does: - The full dataset is already indexed - You can ask natural language questions - Answers are grounded and include direct references to source documents - Supports both exact text lookup and semantic search Discussion around these files is often fragmented. This makes it possible to explore the primary sources directly and verify claims without manually digging through thousands of pages. Happy to answer questions or go into technical details.
