Show HN: Quiet Sky, a weather app built for privacyhttps://github.com/NW-Hiker-Skier/quietsky-privacy-proxyHi, all.I wanted to share an app and privacy proxy I made. I'd appreciate your feedback and thoughts.I've been frustrated for years by the fact that weather apps use our information to track us in real time. I searched high and low for a weather app that promised privacy. I was surprised I couldn't find one. Even apps with good privacy policies make no guarantees about how the provider will use your information. I decided this would be a good time to make an beautiful weather app that delivered on the privacy commitment cleanly.Many of you probably know weather apps are one of the silent ways your location gets sold. The NY Times did a piece on this a few years ago. Most of the apps take your location for a forecast, then pass your that plus your IP and device ID to either directly to ad networks and data brokers, or to providers who then do the same. There are some good apps and providers, but it is difficult to tell. I wanted a weather app that couldn't leak who you are, and I though

Show HN: PAI, a Linux-y personal-assistant for Machttps://www.whitematterlabs.ai/Hi HN!I've been spending the past month on PAI, a Linux-esque harness for a personal assistant AI for your Mac. Instead of giving a chatbot a bunch of tools, I wanted to just drop the LLM into a terminal and see how it'd fare.I've been using it to manage my calendar, 5+ email accounts, and engaging with / responding to people in a timely manner (casus belli for this entire project).After seeing how other always-on assistants were designed, I thought the Unix / Linux philosophy of system design could be applied to AI harnesses, and I wanted to experiment with how it'd hold up compared to them. So, I built PAI with the following things in mind:1. Engaging "code mode" in the LLM (LLMs are natural SDEs / SysAdmins) - If you remember the [code mode](https://blog.cloudflare.com/code-mode/) post from a while ago, I wanted to try and utilize those capabilities within the model for it to naturally interface with the harness rather than trying to load it up with a bunch of exposition. An LLM nat

Show HN: Mochi Analyticshttps://www.mochianalytics.comHey everyone,I wanted to see if I could build something like DataFa.st myself, so I made MochiAnalytics. I'm pretty happy with how it's turning out.It’s got all the bells and whistles a small team or solo founder would need to track campaigns and to see which channel is driving revenue.It’s a cheaper analytics tool for side projects, indie hackers, and small apps. I honestly wish I could make it free, but it still needs servers, a database, and a backend to keep event ingestion running 24/7, so there are real costs behind it.I’m still working on it and will keep adding more features over time. If you have something specific let me know and I can build it.Would love to hear any feedback, good or bad. If anyone is not happy with the pricing, let me know and I can send over a coupon code.Thanks :)

Show HN: Pgconverge – An experimental multi-master PostgreSQL framework in Gohttps://news.ycombinator.com/item?id=48796668Hi HN,Over the past few months I've been building pgconverge, an experimental open-source framework for operating multi-master PostgreSQL clusters.The project started as a learning exercise to better understand distributed databases rather than as an attempt to replace PostgreSQL's existing replication model. My goal was to explore what it would take for multiple PostgreSQL nodes to accept writes independently while eventually converging without relying on a designated primary database. Over time, the experiment evolved into a working open-source framework.Some of the areas I explored include:full-mesh replication topology conflict resolution using Last-Write-Wins Hybrid Logical Clocks for ordering concurrent writes bootstrapping new nodes into an existing cluster declarative cluster configurationGithub Link: https://github.com/sobowalebukola/pgconvergeAlong the way I documented the design decisions in a seven-part engineering series:Why Multi-Master?

Show HN: Sun light and path calculation for photographyhttps://www.lightwindow.appI created this app to accurately calculate light windows like Golden hour, blue hour, etc. for a particular city/location. It helps you plan your photography time by knowing the exact time and direction of sun. It uses swiss ephemeris on the backend to calculate all the path and timings for most accurate data.It also has a 3D view of the sun's path on any day and at any point of the day for the location. Looking at the sun's direction and angle can help you plan your shoot correctly.It is a simple app with no sign-in needed or any ads. Hopefully it helps folks out there. Open to feedback/request for features.Considering an integration with weather APIs if this gains traction and people find it helpful

Ask HN: How Do You "Not Write Any Code by Hand" with a Token Budget?https://news.ycombinator.com/item?id=48796455With some corporate environments going from "tokenmaxxing at all costs" to now setting strict token budgets for agentic development:How is one supposed to adhere to a managerial / leadership instruction of "use AI for everything" but even more than that: "you shouldn't be writing code by hand"?It feels like this is a Russian roulette scenario. As long as you have the right harness, framework, skills, prompt, etc. to make the output as deterministic as possible AND know exactly what you're supposed to be building: you get a great output that meets acceptance criteria & solves the problem.None of this is standardized and concrete tasks don't currently have predictable pricing (i.e., "Two new CRUD endpoints with tests are $1.43"). So what's stopping performance reviews from valuing what you can deliver ONLY with AI rather than what you can deliver with AI assistance?

Show HN: I hated how much my 12-year-old played Roblox, so we built our own FPShttps://cooked.houseI'm a father of two, 7 and 12. They are obsessed with Roblox, especially Rivals.Like a lot of parents, we did not love it. We tried the usual things: block it, limit it, set timers." It became a daily battle, a lose-lose situation.So I flipped the problem.Instead of fighting what they loved, I decided to lean into it, but with a twist.Why just play an FPS when you could build one together?My kids became the PMs. Claude and I became their engineer.I was shocked by how fast we moved. We picked a name, Cooked and started building.Get in. Lock in. Get cooked!In the first 3 hours, we had an actual FPS we could play together in the browser.Next day I invited my friend's two kids over. Suddenly, I had four PMs.We had 3 laptops, 1 iPad and 1 iPhone.So in 30mins we added mobile support and could play all 5 together.The kids would ask for features:"Can we have a rocket launcher that knocks people off the map?""The knife should stab faster when you hold it."I know almost nothing about FPS design,

Show HN: KiCad in the Browserhttps://demo.pcbjam.com/KiCad, a PCB EDA suite is now working in a browser, you can try it at the link, there's a demo project or you can bring your own. Firefox is best, Chrome is good, Safari is "working".We’re Emergence Engineering, a dev shop from Hungary, mostly working with rich text editors, CRDTs. PCBJam started as my (Viktor, CTO, ex-electrical engineer) hobby project but as time went on I put more and more energy into it, and a product started shaping up in my head, in the last few months we’ve started to focus on this project a bit more, and this is the first MVP~ish result.This project is a ton of fun, ton of learning, ton of improvements over improvements:- I thought there must be ways to emulate the PCB canvas OpenGL code on the web. And yes, there are a lot of ways, all of them very buggy. Turns out it’s faster to just write WebGL code that works with KiCad’s Graphics Abstraction Layer if you add the right intermediate debugging steps. I (with Claude) implemented the features and compared them

Show HN: Tracking how much of the HN front page is AI-generatedhttps://www.salahadawi.com/hacker-news-ai-detectorFor the past few months, I've been sending every story that reaches the HN front page through Pangram's AI detector and noting the scores. The reason I made it is that I kept noticing posts that sounded like AI-generated to me. Sometimes the comments pointed it out, sometimes a post was near the top all day and no one said a word. I wondered if the share was really increasing or if I was just primed to see slop everywhere.How it operates: The site identifies the top 30, gets each article, and evaluates the text using Pangram. Besides the live front page view, there are daily and monthly trends, with leaderboards for domains and authors that keep scoring high. I personally find it quite helpful as a sanity check on my own intuition before declaring something AI in the comments.6,500+ stories in, it turns out the front page is still very human after all, which is the part that shocked me the most. A fraction of 13% of stories were AI flagged over the last 30 days. That's slowly ramping u

Show HN: Local MCP – Claude/ChatGPT read your iMessage, Teams, files on-devicehttps://www.local-mcp.com/enI kept hitting the same wall: AI assistants are great until they need my context — the email thread, the calendar, the iMessage, the file on my disk. Cloud connectors can only reach things with a public API, so they physically can't touch the stuff that lives only on my machine.So I built Local MCP — a native macOS app that connects Claude Desktop, Claude Code, Cursor, and ChatGPT to your real local apps over MCP: Mail, Calendar, Contacts, iMessage, Microsoft Teams, Slack, WhatsApp, Notes, Reminders, OmniFocus, OneDrive/Google Drive, Office docs, and local files. ~180 tools.The part I care about most is where the data goes:- Desktop/CLI clients (Claude Desktop, Cursor, Claude Code): everything runs on localhost — nothing leaves your Mac, no API keys, no OAuth to us.- Web AIs (ChatGPT, Claude.ai) that can't reach localhost: there's an optional, opt-in encrypted relay you turn on yourself. It's off by default and it's the only path anything leaves the machine. I flag this explicitly beca
