Show HN: Random Caplocks Prank https://bit.ly/4gnwtL4

Show HN: Random Caplocks Prank I was building a program that needed to allow a user to set a hotkey but the program lives in the taskbar so there's no UI. I decided what I would do is enable the caplock key when they click "Set Hotkey" and then they can disable the caplock key (or set it to its initial state, rather) to indicate they have finished. That project is still going but I got sidetracked by the idea that I could just build a program to randomly enable the caplock key every once in a while. This isn't a program designed to calculate child malnutrition or do anything to stop genocide etc but I was able to do it in a few hours and learn some new tricks. I hope this isn't too stupid for HN. https://bit.ly/3BiZEQG November 29, 2024 at 04:12PM

Show HN: Prompt Engine – Auto pick LLMs based on your prompts https://bit.ly/4ghpC5S

Show HN: Prompt Engine – Auto pick LLMs based on your prompts Nowadays, a common AI tech stack has hundreds of different prompts running across different LLMs. Three key problems: - Choices, picking from 100s of LLMs the best LLM for that 1 prompt is gonna be challenging, you're probably not picking the most optimized LLM for a prompt you wrote. - Scaling/Upgrading, similar to choices but you want to keep consistency of your output even when models depreciate or configurations change. - Prompt management is scary, if something works, you'll never want to touch it but you should be able to without fear of everything breaking. So we launched Prompt Engine which automatically runs your prompts for you on the best LLM every single time with all the tools like internet access. You can also store prompts for reusability and caching which increases performance on every run. How it works? tldr, we built a really small model that is trained on datasets comparing 100s of LLMs that can automatically pick a model based on your prompt. Here's an article explaining the details: https://bit.ly/3VnzkM8... https://bit.ly/4iqUeUr December 6, 2024 at 01:45PM

Show HN: dotnet CMS to build drag-and-drop sites with setup infrastructure We launched PureBlazor CMS today to help .NET devs deploy simple drag-and-drop sites with a fully provisioned infrastructure (AI SEO editor, hosting, security, auth, etc.). Once you’ve built a site, you can hand it over to your non-technical users to run independently. They can drag and drop blocks visually, edit text, and update the site’s SEO with our native AI editor. Please, check out our free trial at https://bit.ly/41hNSkl - we can’t wait to hear what you think. December 5, 2024 at 06:58PM

Show HN: Data Connector – Chat with Your Database and APIs https://bit.ly/3ZFZkFh

Show HN: Data Connector – Chat with Your Database and APIs Hey HN! Wanted to share a project I have been working. Data Connector is an open source tool for interacting with Databases (Postgres, MySQL, SQLite) using natural language. Prompts are handled using a ReAct[1] agent which has access to the schema and a tool for executing queries. It also has experimental[2] support for calling APIs (OpenAPI, GraphQL) which allows for queries that can span multiple systems (Find this user's details in Clerk, etc). We have mostly been using it for managing our local development environment, but it has configurable controls for running in other environments. - Privacy Mode which never sends query results back to the LLM context, instead the result is returned to the user as JSON - Approval Mode which requires manual approval of each query before it is executed Data Connector runs within a private subnet, connects to the database and polls for new queries. There is no requirement to open traffic to the database or share credentials / connection strings. Data Connector is built using another project we are working on Inferable (also open source) which is a runtime for building and observing LLM-based agents. Would love your thoughts! [1] https://bit.ly/3OHp91f [2] We have been testing these with various schemas and are currently working on better handling for large OpenAPI specs, etc. https://bit.ly/3BhdVNM December 6, 2024 at 12:00AM

Show HN: Roast my Spotify Wrapped 2024 I built a small tool that allows users to share their spotify wrapped share link and get roasted by different LLMs. Some fun roasts: "This list makes it sound like you're having a midlife crisis in a thrift store" "You're really pushing the envelope listening to Drake and The Weeknd" "Next year, aim for music that doesn't sound like background noise in an elevator" https://bit.ly/41lT1Yu December 5, 2024 at 05:21AM

Show HN: Minimalboard – A intuitive and fast way to organize work https://bit.ly/4f4fRHx

Show HN: Minimalboard – A intuitive and fast way to organize work Hi HN! Organizing my work has always been frustrating because no tool seemed to fit my workflow. Every app I tried came with endless menus, complicated settings, and more clicking than actually working. If you've ever wrestled with Jira, you know the drill — its great for tracking an army of developers, but a tad overkill for my personal tasks. That's why I built Minimalboard. It combines the simplicity of a good old notepad with the visual organization of a Kanban board. Its sole focus is speed and intuitiveness. Just click to start editing, drag to rearrange, and everything saves automatically. It's a quick, clean workspace to jot down ideas, organize tasks, or capture information on the fly. I've been using Minimalboard privately for two years, and now I'm releasing it to see if I'm the only one with this peculiar obsession for simplicity or if others are equally struggling. Give it a spin and let me know what features you'd find useful. I'm curious to see how much functionality I can stuff in before it starts looking like, well, the tools I was trying to avoid!

Show HN: The Canada census data in a SQLite file; advice appreciated https://bit.ly/49j45Yx

Show HN: The Canada census data in a SQLite file; advice appreciated This is niche, I'll admit. I needed to look through the latest census data, but it was exported as multiple multi-gigabyte bespoke latin1-encoded CSV files. Pandas, Polars, and SQLite's CSV import tool weren't much help, so I shelved the project until recently, when I started taking a SQLite course online. I picked it up again, normalized the data, and now there's a database that can be queried through a SQL view that matches the headings in the original CSVs. I'm proud of the script I created to export the data, as well as automatically compress the artifact, make the diagrams and checksums, etc. This is my first time building up a big database, does my schema seem sane? I've been considering switching the counts from REALs to TEXT, since then SQLite's decimal extension can do exact calculations, but considering there's only one or two places after the decimal points in the data, I'm not sure if it's worth it space-wise. https://bit.ly/49DSPpT December 5, 2024 at 12:20AM

Show HN: A Directory of Free, Open Source Alternatives to Popular Software Hi guys, I want to share the recent project i developed. I built AlternateOSS, a directory of free, open source alternatives and competitors to popular software. Currently, i have listed 200+ tools so far and organized them carefully based on their main functionalities. I ranked them based on its category relevancy and feature completeness. Some technical details & features: - fully static site built with Astro - View Transition API for smooth navigation - Instant/static search with Astro static endpoints If you have an open source project that can be an alternative to popular software, let me know. I will list it on AlternateOSS for free :) Thanks, have a nice day! https://bit.ly/3ZCj8Ju December 4, 2024 at 12:52PM

Show HN: Yeet a cube, an example of AI-powered UX https://bit.ly/4fUye2O

Show HN: Yeet a cube, an example of AI-powered UX A web app that lets you yeet a cube with a natural language request rather than by pressing a button. The code is available at https://bit.ly/3D7xVD1 The AI part is done as a plugin that defines the yeet function and is uploaded to asterai.io which hosts the AI agent. Messages are received in the front-end and decoded with protobuf. Once the yeet request is identified a function is called to yeet the cube with three.js. So this example is serverless (hosted on vercel and asterai for the AI agent), meaning there's no need to manage any server code to implement AI-powered UX use cases such as this (very important) one. https://bit.ly/4gc4xtE December 3, 2024 at 04:18AM

Show HN: Book and change flights with one email https://bit.ly/4fUVeyq

Show HN: Book and change flights with one email Hi there, TLDR; I built an inbox simulator so you can try BonBook in 15s, without sharing your email. Earlier this year I was flying 2-3 times per month and found booking and changing flights a hassle. So I decided to fix it. BonBook lets you find, book and change flights with one email. It can also auto-find flights for events you’re attending. Over the last few days, I built a simulator that lets you interact with BonBook without sharing your email. It responds with real flights and each response includes a link to compare w/ Google. https://bit.ly/3OzEvEW December 3, 2024 at 03:31AM

Show HN: Open-sourced (road) traffic counting application I was developing/selling this application under Roadometry, but sales are getting slow and I'd prefer to make it available for free. This is a desktop Windows application which can be used for counting road traffic. https://bit.ly/3AWXXbK https://www.youtube.com/@roadometry2011 The application uses Multiple Hypothesis Tracking (MHT) combined with Darknet Yolo. I trained the network myself. I have a tool-chain for building a video-based training set including associations, but it's quite complex to use. I never ended up training a network to perform association, but I think a combined detector/associator network is the next step. https://bit.ly/4fWVuNy December 2, 2024 at 11:53PM

Show HN: DailyPings – Like HN, but for maker's daily progress https://bit.ly/3ZxwtTa

Show HN: DailyPings – Like HN, but for maker's daily progress DailyPings ( https://bit.ly/41hCRQ5 ) is a HN-inspired platform where makers share their daily progress. Key features: - Three posts per day limit to encourage quality updates - HN-style upvote system - No comments, just pure progress sharing - Email verification Tech stack: - Next.js 15 App Router - TypeScript - Prisma ORM - PostgreSQL - NextAuth.js - Tailwind CSS - Geist Mono font - Deployed on Coolify The idea came from wanting a distraction-free space for makers to share their daily progress, similar to how HN works for tech news. The three posts per day limit is intentional - it encourages users to share their most meaningful updates rather than constant micro-updates. I'd love to get feedback from the HN community, especially on: 1. The minimalist approach 2. The daily post limit concept 3. Future features you'd like to see This is my first Show HN. The platform is live and ready for users. https://bit.ly/41hCRQ5 December 1, 2024 at 01:18AM
