Show HN: Linex – A daily challenge: placing pieces on a board that fights back 7 by Humanista75 | 6 comments on Hacker News. Hi HN, I wanted to share a web game I’ve been building in HTML, JavaScript, MySQL, and PHP called LINEX. It is primarily designed and optimized to be played in the mobile browser. The idea is simple: you have an 8x8 board where you must place pieces (Tetris-style and some custom shapes) to clear horizontal and vertical lines. Yes, someone might think this has already been done, but let me explain. You choose where to place the piece and how to rotate it. The core interaction consists of "drawing" the piece tap-by-tap on the grid, which provides a very satisfying tactile sense of control and requires a much more thoughtful strategy. To avoid the flat difficulty curve typical of games in this genre, I’ve implemented a couple of twists: 1. Progressive difficulty (The board fights back): As you progress and clear lines, permanently blocked cells randomly...

Show HN: Django Control Room – All Your Tools Inside the Django Admin 21 by yassi_dev | 6 comments on Hacker News. Over the past year I’ve been building a set of operational panels for Django: - Redis inspection - cache visibility - Celery task introspection - URL discovery and testing All of these tools have been built inside the Django admin. Instead of jumping between tools like Flower, redis-cli, Swagger, or external services, I wanted something that sits where I’m already working. I’ve grouped these under a single umbrella: Django Control Room. The idea is pretty simple: the Django admin already gives you authentication, permissions, and a familiar interface. It can also act as an operational layer for your app. Each panel is just a small Django app with a simple interface, so it’s easy to build your own and plug it in. I’m working on more panels (signals, errors, etc.) and also thinking about how far this pattern can go. Curious how others think about this. Does it make sense ...

Show HN: Nerve: Stitches all your data sources into one mega-API 3 by mprast | 0 comments on Hacker News. Hi HN! Nerve is a solo project I've been working on for the last few years. It's a developer tool that stitches together data from multiple sources in real-time. A lot of high-leverage projects (AI or otherwise) involve tying data together from multiple systems of record. This is easy enough when the data is simple and the sources are few, but if you have highly nested data and lots of sources (or you need things like federated pagination and filtering), you have to write a lot of gnarly boilerplate that's brittle and easy to get wrong. One solution is to import all your data into a central warehouse and just pull it from there. This works, but 1) you need a warehouse, 2) you have an extra copy of the data that can get stale or inconsistent, 3) you need to write and manage pipelines/connectors (or outsource them to a vendor), and 4) you're adding an extra point o...

Show HN: I built a macOS tool for network engineers – it's called NetViews 5 by n1sni | 0 comments on Hacker News. Hi HN — I’m the developer of NetViews, a macOS utility I built because I wanted better visibility into what was actually happening on my wired and wireless networks. I live in the CLI, but for discovery and ongoing monitoring, I kept bouncing between tools, terminals, and mental context switches. I wanted something faster and more visual, without losing technical depth — so I built a GUI that brings my favorite diagnostics together in one place. About three months ago, I shared an early version here and got a ton of great feedback. I listened: a new name (it was PingStalker), a longer trial, and a lot of new features. Today I’m excited to share NetViews 2.3. NetViews started because I wanted to know if something on the network was scanning my machine. Once I had that, I wanted quick access to core details—external IP, Wi-Fi data, and local topology. Then I wanted mo...

Show HN: Pipelock – All-in-one security harness for AI coding agents 12 by pipejosh | 2 comments on Hacker News. I'm a plumber who taught himself to code. I run a plumbing company during the day and mess with my homelab at night. About a year ago I started running AI agents with full shell access and API keys to help manage my business. Scheduling, invoicing, monitoring my K3s cluster. It worked great until I realized nothing was stopping those agents from sending my credentials anywhere. I had API keys for Slack, email, cloud services, all sitting in environment variables that any tool call could exfiltrate. Static scanners check code before you install it, but they can't catch a trusted tool that decides to phone home at runtime. So I built Pipelock. Single Go binary, sits between your AI agent and the outside world. What it does: - Scans all outbound traffic for secrets (API keys, tokens, passwords) and blocks them before they leave - Blocks network access to unauthorized...

Show HN: Total Recall – write-gated memory for Claude Code 15 by davegoldblatt | 10 comments on Hacker News. built this because I got tired of re-teaching Claude Code the same context every session. Preferences, decisions, “we already tried X,” “don’t touch this file,” etc. After a few days it starts to feel like onboarding the same coworker every morning. Most “agent memory” tools auto-save everything. That feels good briefly, then memory turns into a junk drawer and retrieval gets noisy. Total Recall takes the opposite approach: a write gate. Before anything gets promoted, it asks one question: “Will this change future behavior?” If not, it doesn’t get saved. How it works: Daily log first (raw notes) Promote durable stuff into registers (decisions, preferences, people, projects) Small working memory loads every session (kept intentionally lean) Hooks fail open. SessionStart can surface open loops + recent context. PreCompact writes to disk (not model-visible stdout) The holy shit ...

Show HN: Algorithmically Finding the Longest Line of Sight on Earth 35 by tombh | 10 comments on Hacker News. We're Tom and Ryan and we teamed up to build an algorithm with Rust and SIMD to exhaustively search for the longest line of sight on the planet. We can confirm that a previously speculated view between Pik Dankova in Kyrgyzstan and the Hindu Kush in China is indeed the longest, at 530km. We go into all the details at https://alltheviews.world And there's an interactive map with over 1 billion longest lines, covering the whole world at https://map.alltheviews.world Just click on any point and it'll load its longest line of sight. Some of you may remember Tom's post[1] from a few months ago about how to efficiently pack visibility tiles for computing the entire planet. Well now it's done. The compute run itself took 100s of AMD Turin cores, 100s of GBs of RAM, a few TBs of disk and 2 days of constant runtime on multiple machines. If you are interested in th...

Show HN: Craftplan – Elixir-based micro-ERP for small-scale manufacturers 4 by deofoo | 0 comments on Hacker News. My wife was planning to open a micro-bakery and we started looking at software to manage recipes, inventory, orders, and production. Everything was either expensive, too generic, or both. The workflows for a small-batch manufacturer aren’t that complex, but the pricing acts like they are. So I built Craftplan. All the features were tailored to what she actually needed, and I figured other small-scale manufacturers (soap makers, breweries, candle makers, etc.) probably need the same things. So I’m putting it out there for free. - Live demo: https://ift.tt/pSK1ue6 (test@test.com / Aa123123123123) - GitHub: https://ift.tt/OQNXyYt - Docs: https://puemos.github.io/craftplan - Self-hosting guide: https://puemos.github.io/craftplan/docs/self-hosting/ What it does: - Product catalog with versioned recipes (BOMs) and automatic cost rollups across materials, labor, and overhead -...

Ask HN: Where do all the web devs talk? 5 by LinguaBrowse | 1 comments on Hacker News. I've been using Twitter / X for a good decade now, and while I've found it's a great place to connect with native app dev communities (I'm well connected with the React Native scene), I really struggle to connect with any web devs. There are a few big names like Adam Wathan who are pretty active on Twitter of course, but considering how widespread web dev is, I see precious few up-and-coming web devs coding in public. So, where are they? I have explored BlueSky a bit, but again it feels a bit like tumbleweeds (though maybe that's just my luck as a small account). Are web devs more old-school, posting on bulletin boards and forums? Or is X still the answer, and I'm just getting aggressively packed into a different bubble? … Or is it all realtime communication, like Slack and Discord, these days?
