Show HN: AI-assisted approach to detecting patterns in network traffic https://ift.tt/ZpXS6E8

Show HN: AI-assisted approach to detecting patterns in network traffic I’ve been experimenting with an AI-assisted approach to detecting patterns in network traffic. For context, I maintain a project called Phone Home Detector, which analyses traffic between IP address pairs. It aggregates traffic into one-minute buckets and applies a set of fixed rules based on byte counts and transmission intervals. I recently prototyped an extension that exposes transmission size and timing data through an MCP tool, making it queryable by an LLM. The goal is to explore whether an LLM can identify patterns that are difficult to capture using static rules alone. This work is still experimental, and I’m not yet convinced it is an improvement over fixed-rule approaches. That said, I do find it interesting, and it may be a foundation for further exploration. The following is an example of a summary that it generates: The data sizes sent to IP address 91.189.91.49 are mostly consistent at 200, after an initial size of 168, and the intervals at which they are sent vary without any apparent pattern. https://ift.tt/AtGDKI7 December 29, 2025 at 02:21AM

Show HN: Matchstick Puzzle Game in the Browser An older family member showed me these puzzle games that he was playing via YouTube videos. I wanted to make them more playable in a frictionless way, so I generated all possible combinations for these types of puzzles and put together an interface for them. https://matchmath.pages.dev/ December 29, 2025 at 01:37AM

Show HN: Databasus – open-source backup tool for PostgreSQL, MySQL and MongoDB I had a post in the start of December about Postgresus 2.0: self hosted tool for PostgreSQL. Since then the project changed the name and added support of other databases: MySQL, MariaDB and MongoDB. Website - https://databasus.com GitHub - https://ift.tt/yeUrSWx Main features: - Scheduled backups for multiple PostgreSQL, MySQL, MariaDB and MongoDB databases - Storage to S3, Cloudflare R2, Google Drive, Azure Blob, NAS, SFTP, rclone, etc. - Notifications about backup status via email, Telegram, Slack, Discord, MS Teams and customizable webhooks - Works with both self-hosted and managed PostgreSQL (RDS, Cloud SQL, etc.) - Runs as a single Docker container or via Helm on Kubernetes, can be installed via script - There are workspaces and role-based access with audit logs https://databasus.com December 28, 2025 at 09:38AM

Show HN: attainable – The fastest and easiest way to design and deploy APIs https://ift.tt/YDKWHBq

Show HN: attainable – The fastest and easiest way to design and deploy APIs This began as a passion project and an opportunity to learn new tech. I've always experienced frustration developing APIs, especially the RESTful CRUD style of data APIs. It always felt like I was repeating the same patterns over and over again, and that was tedium I didn't want. A little over a year ago, I wanted to learn more about Go, Firecracker microVM, and Svelte and thought "Could I build an API framework that was just a simple description of resources? What would that look like?" That lead me to https://firecracker-microvm.github.io/ , which landed me on https://fly.io , then https://rqlite.io , and the further I got into it, the more I really liked what I had. It's been over a year of learning and trying out all forms of tooling, CLIs, LSPs, and finally I landed on this. So I decided to try my hand at making this a product. I'd really enjoy feedback about it and whether it's something folks would use. Here's hoping others feel the way I do about APIs and the developer experience building them! https://attainable.dev December 27, 2025 at 09:14PM

Show HN: I Made a Tiny Stranger Things Game While Waiting for the Finale https://ift.tt/k1lKPxV

Show HN: I Made a Tiny Stranger Things Game While Waiting for the Finale I made this for my wife, who’s a big Stranger Things fan, to keep her entertained while we wait for the final episode coming out in a few days. Built in ~2 hours. It’s a short clicker game (~15–20 minutes) and it actually ends. I personally love the tree ui, if I spent more time i'd definitely improve the performance and replace those emojis with actual images. https://ift.tt/vYPGwkZ December 27, 2025 at 07:57PM
