Show HN: Standardising 'Unit Tests' for Prompts PromptRepository is an open-source framework (Typescript) that illustrates an approach to creating more reliable LLM-based applications through systematic prompt validation, and testing. Key features: - Simple JSON schema for externalized prompts with versioning and parameter validation - Lightweight approach inspired by Anthropic's guidance to "keep it simple" with LLM applications - 'Unit tests for Prompts' inspired by Chris Benson/Practical AI's recommendations from episode 295. - Bundled prompts to generate unit tests and evaluations for new prompts built with the framework. The framework demonstrates a novel approach: bundle tested prompts with a framework that generate code to use the framework.

Show HN: Hexi, modern header-only network binary serialisation for C++ hackers Over the last few years, I've needed an easy way to quickly serialise and deserialise various network protocols safely and efficiently. Most of the libraries that existed at the time were either quite heavy, had less than stellar performance, or were an abstraction level above what I was looking for. I decided to put together my own class to do the job, starting with an easy, low-overhead way to move bytes in and out of arbitrary buffers. Along the way, it picked up useful bits and pieces, such as buffer structures and allocators that made the byte shuffling faster, often being able to do it with zero allocations and zero copies. Safety features came along to make sure that malicious packet data or mistakes in the code wouldn't result in segfaults or vulnerabilities. It's become useful enough to me that I've packaged it up in its own standalone library on the chance that it might be useful to...

Show HN I built an open source alternative to wakatime because I don't think a wakatime premium should cost more than a Github copilot subscription. The problem wakatime solves is rather straightforward. Their hardest bit of business is creating all those plugins, besides that the backend just ingests plugin data and organizes it into a dashboard that gives insights into developer work habits. I also felt features like goals, invoices and management of clients shouldn't require premium subscription. And for the most part, I feel I'm right. Especially after implementing these features. The website is now in beta testing and I'd love your feedback on some of the metrics you'd like to see that are not currently on the wakatime website. I've already added stats about the amount of coding time spent writing code. And for me it feels like a big deal thus far. I've also been playing with an idea of showing developer focus/attention as buckets of heartbeats over tim...

I made LiteRead.ai, a Chrome & Firefox extension that summarizes individual posts, articles, and discussions on Reddit, Hacker News, and even YouTube videos. The idea came from wanting a faster way to skim articles, YT videos, posts, and comments. LiteRead adds a simple "Summarize" button that gives you the key takeaways in various formats: brief, detailed, & notes. It's free to signup and try, and has a pay-to-go pricing model if you decide it's useful for you. This is my first launch, and I'd love feedback on how it could be improved. Some things I'm considering next: - Supporting more sites/platforms - Adding more customization for summary style & length - Supporting more browsers Check it out here: https://literead.ai Thanks for giving ...

Show HN: No one cares about observability costs Morning HN - - I have a quick story about building a startup and misreading the market, and an ask. (The ask: Try out our product>> https://ift.tt/sdKpLBq ) My name is Julian Giuca and I was an early employee at New Relic, where I led their Logging product until 2022. It’s safe to say I have opinions about logs. Sometimes I think they are great. Too often I think we can do much better. When people talk to me about logs, they reliably complain about observability costs. Engineering leaders have said it feels “like a protection racket”, where you're forced to capture and send everything with no real levers of control. So I wanted to address this and built the ideal streaming pipeline to shape and route data. Basically Cribl for Datadog. If you can shape, filter, and route logs intelligently, you can slash your observability bill. Sending less data means spending less money. Coinbase had just spent $65M on Datadog (in 2023)!

Show HN: Fingernotes – handwritten notes which become their own preview image Hi HN, I've lurked here for ages and decided to come out of the shadows for my latest side project which reached the point where it’s sort of fun to use and hopefully not totally embarrassing to share. Hacking fingernotes.com together over a couple of weeks was a creative outlet when work got stressful. I think of it as digital sticky notes. The goal was to make notes with a personal touch that are easy to write and share. I also wanted them to appear as their own link preview image on supported platforms. That way when you send the link to a note, the person sees the message without following the link. Let me know what you think! I drew inspiration from Apple's quick notes: low latency made scribbling a pleasure, and sending notes to friends felt warm and original compared to a typical exchange. It was also intriguing to see my handwriting printed in a message chat. In a time of rising artificial gen...

Show HN: BlinkAlarm - Prevent eyestrain, dryness with real-time computer vision! I often struggle with dry, strained eyes from long duration computer usage. It turns out when focusing intently, human blink rates decline from a healthy 15-20 per minute to 3-4 (or even fewer in some cases). I wrote a quick script that calculates facial landmarks on your webcam feed in realtime and plays a sound if you fail to blink for a configurable number of seconds. I use the common way of detecting a blink, which is to calculate the ratio between the height and width of the visible portion of the eye. This can be done with just 6 landmarks -- two on the upper eyelid, two on the lower eyelid, and one on either side of the eye. I found that this doesn't work well in all angles / postural positions, so I also augment this with another metric that corrects for head tilt. It's not perfect (if you tilt your head such that your ear is brought closer to your shoulder, it may over-detect blinks) but i...

Show HN: XYMake – Turn Your Posts into LLM-Ready Data I just built XYMake ( https://xymake.com ), a tool that lets you convert any X (Twitter) thread into clean markdown, making your conversations accessible for LLMs, MCPs, or any API. ## What it does: - Transforms any X thread URL into markdown by simply changing "x.com" to "xymake.com" in the URL - OAuth2 login to "free your data" and make your threads available - Auto-generates OG images with token counts and participant info for easy sharing - Serves different content types based on whether the request is from a crawler, browser, or agent ## Why I built it: I believe people should have the right to own and use their own data.

I'm excited to share GoCard, a terminal-based spaced repetition system I built that uses plain Markdown files as its data source. I've always been frustrated with existing spaced repetition tools that lock my knowledge into proprietary formats or require constant internet access.

Show HN: AgentKit – JavaScript Alternative to OpenAI Agents SDK with Native MCP Hi HN! I’m Tony, co-founder of Inngest. I wanted to share AgentKit, our Typescript multi-agent library we’ve been cooking and testing with some early users in prod for months. Although OpenAI’s Agents SDK has been launched since, we think an Agent framework should offer more deterministic and flexible routing, work with multiple model providers, embrace MCP (for rich tooling), and support the unstoppable and growing community of TypeScript AI developers by enabling a smooth transition to production use cases. This is why we are building AgentKit, and we’re really excited about it for a few reasons: Firstly, it’s simple. We embrace KISS principles brought by Anthropic and HuggingFace by allowing you to gradually add autonomy to your AgentKit program using primitives: - Agents: LLM calls that can be combined with prompts, tools, and MCP native support. - Networks: a simple way to get Agents to collaborate wit...

There's no prompting involved.

Our goal was to put the advanced ML and DS techniques we’ve been using in the hands of all software engineers, so that everyone can build AI and Search apps at the same level of performance and sophistication as the big labs. This was a hard technical challenge but we were very inspired by the MVC architecture for Web development. The intuition there was that when a data model changes, its view would get auto-updated. We built a similar architecture for AI. On one side is a scoring system, which encapsulates in a set of metrics what’s good about the AI application. On the other side is a set of optimizers that “compile” against this scorer - prompt optimization, data filtering, synthetic data generation, supervised learning, RL, etc. The scoring system can be calibrated using developer, user...

To give an example, some models like mixtral-ocr only try to convert a document to markdown format. You have to use another LLM on top of it to get the final result. Some VLM’s directly give structured information like key fields from documents like invoices, but you have to either add business rules on top of it or use some LLM as a judge kind of system to get sense of which output needs to be manually reviewed or can be taken as correct output. No benchmark attempts to measure the actual rate of automation you can achieve.

Show HN: Time Portal – Get dropped into history, guess where you landed Hi HN! I love imagining the past, so I made Time Portal, a game where you are dropped into a historical event and see AI video footage from that moment. You have to guess where you are in time and on the map. It’s like GeoGuessr (and heavily inspired by it!) but for historical events. The videos are all created with AI. It’s a pipeline of Flux (images), Kling (video), and mmaudio (audio). The videos aren’t always historically accurate to the last detail. They might incorporate elements of folklore or have details from popular beliefs about the way things looked rather than the latest academic research on how they looked. I’m thinking a lot about how to make the game more interactive. One thing that makes Geoguessr so fun for me is that you can move infinitely and always find more details to help you pinpoint the location. I want Time Portal to have a similar quality.

Show HN: Nuanced – Help AI understand code structure, not just text Hi HN! We built Nuanced ( https://ift.tt/LewCVDg ), an open-source Python library that makes AI coding tools smarter about code structure. The problem: current AI coding assistants see code as just text. They don't understand which functions call which, or how code components depend on each other. This is why they often suggest changes that break dependencies they should have known about. Nuanced solves this by generating call graphs that map these relationships. When you ask "What would break if I change this function?", instead of guessing, the AI can see the actual dependencies. How it works: 1. Run `nuanced init .` to analyze a Python module in your codebase 2. Use `nuanced enrich app/file.py function_name` to get relationship data 3. Include this data in your AI prompts or integrate it into tools We're already working with teams building AI coding assistants and security review tools to integrate...

Show HN: I built a Figma plugin for quick data calculations I lead design on a B2B SaaS product. It's quite data-heavy in places. Using placeholder content in data tables, checkout summaries and dashboards is a big no-no for us. It might seem like using random numbers saves time at first, but sooner or later there's documentation to write and plenty of clarifications to be made. It throws off customers during interviews – "hey, that's not really my sales target!". It confuses stakeholders at review time– "what's this data point supposed to be?" I built a Figma calculator plugin for my team so that they spend less time doing mental maths. It calculates sums, differences averages and percentages, and makes it easy to use real-looking data in designs. https://ift.tt/MmKcOCk March 10, 2025 at 08:41PM

Riding the Rails: San Francisco Cable Car Stamps By Kelley Trahan Evening shot of a cable car on Powell Street with passengers, February 29, 1968 San Francisco's iconic cable cars aren't just a beloved tourist attraction. They are a symbol of the city's unique history and ingenuity. And they’ve appeared on two United States postage stamps. Let's take a journey through the history of these tributes and see how they came to be. The first ride: the 1971 cable car stamp The first cable car stamp was released in 1971. It was an 8-cent historic preservation stamp honoring the San Francisco cable cars. It showed the cable car's charm and was a small tribute to the...

Show HN: SQLite vs. GoatDB: Surprising Benchmark Results for a New Realtime NoDB We introduced GoatDB just three weeks ago and have been blown away by the community’s response. Your feedback and excitement genuinely exceeded our expectations—so first and foremost, thank you from all of us! For anyone just hearing about it: GoatDB is a real-time, version-controlled NoDB for Deno and React that’s edge-native, meaning it requires only minimal backend infrastructure without heavy server components. It’s designed for prototyping, self-hosting, single-tenant apps, and even ultra-light multi-tenant setups if you want to keep your backend minimal. One of the biggest requests we heard was, “Where are the benchmarks?” We’re thrilled to share them now. The numbers tell an interesting story: in some tests, our distributed-commit-graph architecture can be significantly slower than SQLite; in others, it’s surprisingly faster. This is what happens when you put synchronization and collaboration first ...

Show HN: Llama-8B Teaches Itself Baby Steps to Deep Research Using RL I've been tinkering with getting Llama-8B to bootstrap its own research skills through self-play. The model generates questions about documents, searches for answers, and then learns from its own successes/failures through RL (hacked up Unsloth's GRPO code). Started with just 23% accuracy on Apollo 13 mission report questions and hit 53% after less than an hour of training. Everything runs locally using open-source models. It's cool to see the model go from completely botching search queries to iteratively researching to get the right answer. https://ift.tt/12czdvT March 10, 2025 at 11:05PM

Show HN: Evolving Agents Framework Hey HN, I've been working on an open-source framework for creating AI agents that evolve, communicate, and collaborate to solve complex tasks. The Evolving Agents Framework allows agents to: Reuse, evolve, or create new agents dynamically based on semantic similarity Communicate and delegate tasks to other specialized agents Continuously improve by learning from past executions Define workflows in YAML, making it easy to orchestrate agent interactions Search for relevant tools and agents using OpenAI embeddings Support multiple AI frameworks (BeeAI, etc.) Current Status & Roadmap This is still a draft and a proof of concept (POC). Right now, I’m focused on validating it in real-world scenarios to refine and improve it. Next week, I'm adding a new feature to make it useful for distributed multi-agent systems. This will allow agents to work across different environments, improving scalability and coordination. Why? Most agent-based AI framew...

Show HN: Rio – Open Source Web Apps in Pure Python, No JS/HTML/CSS Needed Hey HN, Over the past 10 months, my friends and I created an open source project called Rio to help Python developers build modern web apps without needing HTML, CSS, or JavaScript. Whether you're working on a simple internal tool or a complex multi-page app, Rio lets you stay in the Python ecosystem without needing to learn frontend frameworks. With Rio, the UI is defined using Python components, inspired by React and Flutter. Instead of writing HTML/CSS, you compose reusable UI elements in Python and let Rio handle rendering and state updates. The backend and frontend stay seamlessly connected using WebSockets, so data syncs automatically without manual API calls. Since Rio is fully Python-native, you can integrate it with any Python library, from data science tools to AI models. Many Python projects rely on popular libraries like React internally, but the core benefits and elegance of these libraries are o...

Show HN: A big tech dev experience for an open source CMS # Show HN: A big tech dev experience for an open source CMS. Hey HN! We're building an open-source CMS designed to help creators with every part of the content production pipeline. We're showing our tiny first step: A tool designed to take in a Twitter username and produce an "identity card" based on it. We expect to use an approach similar to [Constitutional AI] with an explicit focus on repeatability, testability, and verification of an "identity card." We think this approach could be used to create finetuning examples for training changes, or serve as inference time insight for LLMs, or most likely a combination of the two. The tooling we're showing today is extremely simplistic (and the AI is frankly bad) but this is intentional. We're more focused on showing the dev experience and community aspects. We'd like to make it easier to contribute to this project than edit Wikipedia. Communi...

Show HN: Fast-agent – Compose MCP enabled Agents and Workflows in minutes Hello, HN. I've created fast-agent to make building my own products easier - and remove the friction between defining Prompts, MCP Servers and their composition. It uses a simple, declarative style that's easy to work with and source control - with inbuilt support for the patterns in the Building Effective Agents paper. Because you can "warm-up" and interact with Agents before, during or after the workflows, it's easy to diagnose and tune Agent prompts and behaviour for later runs. Being able to set these workflows up makes LLM Context Management and Tool Selection a lot easier and can vastly improve output quality for little effort. For MCP Server developers you can see how different models interpret tool descriptions. There's also MCP Roots support, and it comes bundled with a ChatGPT style data-analysis tool (`fast-agent bootstrap data-analysis`) as one of the demonstrations. One of t...

Show HN: PG-Capture – a better way to sync Postgres with Algolia (or Elastic) Hello HN! Keeping Elasticsearch or Algolia in sync with Postgres is a pain when your data spans multiple tables. Traditional CDC tools like Debezium capture table-level events but don’t help when you need to index a full entity composed of related records. That's why I built PG-Capture. PG-Capture lets you define a schema as complex as you need, aggregate table-level events, and reconstruct structured objects spanning multiple tables. It then publishes them as meaningful domain-level events to any queue (RabbitMQ, SQS, etc.). PG-Capture does NOT replace Debezium, it works on top of it (or any other event source). This keeps it flexible and tool-agnostic. I'd love to hear your thoughts! Does this solve a problem you've run into? Would you use something like this in your stack? Feedback is welcome! https://ift.tt/1L5Y3Pe March 1, 2025 at 04:18PM

You can listen to some cool Staff Picks songs from the latest version here https://sonauto.ai/ , listen to an acapella song I made for my housemate here https://ift.tt/CnRUVlP , or try the free and unlimited generations yourself. However, given there are only two of us right now competing in the "best model and average user UI" race we haven't had the time to build some of the really neat ideas our users and pro musicians have been dreaming up (e..g, DAW plugins, live performance transition generators, etc). The hacker musician community has a rich history of taking new tech and doing really cool and unexpected stuff with it, too. As such, we're opening up an API that gives full access to the features of our underlying diffusion model (e.g., generation, inpainting, extensions, transition gen...

Show HN: Mmar – open-source, zero-dependancy, cross-platform HTTP tunneling Hey HN! For the past couple of months, I've been working on and off on a cool project I'm excited to share. mmar (pronounced "ma-mar") is an open-source, zero dependency, cross platform and self-hostable HTTP tunnel built in Go. It allows you to easily expose your localhost to the world on a public URL. You can easily create an HTTP tunnel right away for free on a randomly generated subdomain on "*.mmar.dev" if you don't feel like self-hosting. This isn't something new, in fact there's quite a few of alternative HTTP tunneling tools out there. mmar is my attempt to optimize for a super easy developer experience and simplified implementation. None the less, I had a blast building it and I think developers could find it pretty useful. Additionally, I documented the whole process of building mmar through devlogs. You can read about the thought process and implementation deta...

Show HN: Fast Transition from Firefox to Librewolf After looking at various browser alternatives to Firefox (my daily driver for years), I decided to try LibreWolf and the transition was trivial on a Debian based system (by HN standards). My extensions even ran without logging in (YMMV). First install LibreWolf: sudo apt update && sudo apt install extrepo -y sudo extrepo enable librewolf sudo apt update && sudo apt install librewolf -y Second: After closing Firefox, copy Firefox profile (in ~/.mozilla/firefox/) to Librevox profile (in ~/.librewolf/). Note: I copied the profile into the default profile (as seen in about:profiles) not default-default. I then launched the profile and all my tabs were restored, bookmarks, logins, etc. I will update if something seems broken. March 3, 2025 at 01:14AM
