Show HN: AuthorTrail – Browse files you've touched in a Git repo This was more so an exercise in prompting with Lovable and Cursor than it was in creating a highly polished product/tool. Yet the end result works :) AuthorTrail is a locally running web UI that you can point to any Git repo. It will then look for all the files you have ever touched. This can be useful for large repos with lots of activity, where you want to remind yourself how you did something in the past. For example, I am using it to remind myself how I wrote an obscure unit test, without needing to browse my older PRs. Feedback welcome! https://bit.ly/3BMhyLX December 22, 2024 at 11:18AM

Show HN: Organize Your Blood Tests into a Beautiful Health Dashboard https://bit.ly/4fzinFG

Show HN: Organize Your Blood Tests into a Beautiful Health Dashboard I've been really into tracking my biomarkers lately. However, I've found it a pain to deal with blood test reports from different healthcare providers, each with their own unique format. So I built a solution - a web app that automatically extracts biomarkers from any blood test report and organizes them into a beautiful health dashboard, complete with trend graphs. No more manual data entry into spreadsheets! Check it out: https://bit.ly/4gkTsHf It's a free web app that: * Automatically extracts biomarkers from any blood test report (PDF or image) * Creates visual trends of your health metrics over time * Provides basic medical information about the extracted biomarkers You can try it yourself or check out the demo dashboard on the website to see how it works. I’d love to hear your thoughts and ideas on how I can market it. https://bit.ly/4gkTsHf December 24, 2024 at 12:57AM

Show HN: A registry of agent benchmarks (including many OSS agent trajectories) If you're interested in exploring what LLM-based agent systems these days actually do to solve certain benchmarks such as SWEBench or WebArena, we created a small leaderboard with our team, that allows to view a lot of public and OSS agent results including all the runtime traces (the step-by-step reasoning behind the scenes). Looking at traces is actually quite interesting, as they reveal a lot about the inner working and shortcomings of current agent system, e.g. see https://bit.ly/4gplkdl... for an example trace. https://bit.ly/4grYPVa December 23, 2024 at 09:57AM

Show HN: I built this website about Sikh History and don't know how code works I've been learning about Sikhism and Sikh history recently and, despite having Game of Thrones level drama, I found the resources really lacking and nowhere piecing it all together. I work in a developer adjacent role (ok, I'm a Product Manager) but despite working with software engineers every day I don't really get coding. I see a lot of stuff online about the death of software engineers and wanted to challenge myself to see if I could create something myself. I've been using the free tier of Anthropic's Claude AI, deployed on the free Vercel tier, spent $10 on the domain but not a penny more on anything else. It's super basic but felt good to make something myself and I learned a lot. I'd brick it at the idea of adding anything complex (or even being asked how it all works together) so I'm sure developers are safe for a while yet! https://bit.ly/3ZSY6VZ December 23, 2024 at 06:01AM

Show HN: Yakari – Interactive TUIs for CLI Tools Hi HN! I wanted to share Yakari, a tool I built to make command-line interfaces more approachable through interactive TUIs. If you've ever forgotten CLI flags or needed to look up command syntax, this might help. Yakari turns complex commands into interactive menus. Users can navigate through options with simple key presses instead of memorizing complex command structures. If you've used Emacs and Magit (or any other Transient) before, the interface will feel familiar. Features: - Transform CLIs into guided menus - Create custom menus for any CLI - Support for flags, named parameters, choices, and interactive inputs - Command history and contextual help You can try it out without installing thanks to uv [1]: uvx --from yakari ykr demo # Play with a demo showcasing different argument types uvx --from yakari ykr git # Try the git menu in any git repo The project is built with Python using Textual and is heavily inspired by Emacs' Transient. I'd love feedback from both CLI users and developers. What tools would you find most useful to have menus for? How could this make your terminal workflows easier?

Show HN: A simple air quality app https://bit.ly/3ZWvdJH

Show HN: A simple air quality app I made this app for myself, but it's probably worth sharing. When I tried to find a nice app that I could use to check air quality multiple times a day, I was shocked. All of them looked boring with traffic-light coding and overcrowded with unnecessary data. On top of that, they either contained ads or required payment. I didn't want to use any of those apps every day, so I thought, "Well, how hard could it be?" and accepted the challenge. I expected to finish development in a month, but since I'm a designer and don't normally program apps, I had to learn Swift on the go. This required a month more than I expected. In my designs, I'm usually way too focused on efficiency. Since this was my personal project, I wanted to experiment, so I didn't use standard controls or color coding. Inspired by avant-garde style, I used forms and movement to convey air quality, as well as an asymmetrical layout and overflowing visualizations. I enjoy using the app, and I hope you will, too. https://apple.co/4iIt4ZC December 18, 2024 at 12:19AM

Show HN: Convert PDF invoices to e-invoice XML using AI in seconds https://bit.ly/3OZaNcE

Show HN: Convert PDF invoices to e-invoice XML using AI in seconds I got approached by the finance department of a large company. There is a new regulation in Europe that mandates a defined XML-format for e-invoices for some transactions and - I kid you not - their SAP implementation wasn't able to address this. They also said that all solutions on the market were either cumbersome (think: manually typing in all fields) or required deep system integration. I thought it cannot be that hard to use AI for this and built a little invoice converter that takes your PDF invoice in whatever form it is, and outputs exactly the XML structure that is required in the regulation. Given that AI is not perfect (but surprisingly close to it!), you can manually edit all fields. Target users are companies where their current solution does not yet support the standard and that do not want to change their existing invoicing flow (incl. foreign businesses). Trying it out is free. Given this is my first real B2B tool, would love some feedback! https://bit.ly/3OY0l5e December 16, 2024 at 10:52PM

Show HN: I designed an espresso machine and coffee grinder from scratch https://bit.ly/3VDAROp

Show HN: I designed an espresso machine and coffee grinder from scratch It was a lot of work as a solo project but I hope you guys think it’s cool. When I say “we” in the website it’s only in the most royal sense possible. I also did all the photo/videography. I started out designing a single machine for personal use, but like many things it sort of spiraled out of control from there. I felt like espresso machines were getting very large, plasticky, and app-integrated without actually improving the underlying technologies that make them work. The noisy vibratory pumps in particular are from 1977 and haven’t really changed since then. So I wanted to focus on making the most advanced internals I could and leaving everything else as minimalist as possible. The pump is, as far as I know, completely unique in terms of power density and price. Without spending several thousand dollars, it was difficult to find a machine with a gear pump, and adjustable pressure was also similarly expensive but this machine has those things and costs a normal amount to buy. You can also turn the pressure way down and make filter coffee. I also saw so many people (including myself) using a scale while making espresso, and even putting a cup below the group head to catch drips, entirely negating the drip tray, so I basically designed for that! The profile of the machine is much lighter on the eyes and doesn’t loom in the corner like my old espresso machine did. And for the grinder, basically everything on the market uses conical and flat burrs that have descended from spice grinders, and the same couple of standard sizes. Sometimes larger companies design their own burrs, but only within those existing shapes. There is sort of a rush to put larger and larger burrs into coffee grinders, which makes sense, but with cylindrical burrs, you can increase the cutting surface way more relative to the size of the grinder. When grinders get too big, maintaining alignment becomes mechanically cumbersome, but the cylindrical burr can be very well supported from the inside, and there is the added benefit of hiding the entire motor within the burr itself. The resulting grounds are just outright better than all the other grinders I have used, but obviously this is a matter of taste and my own personal bias. The biggest downside for the grinder is that it doesn’t work with starbucks style oily roasts, because the coffee expands so much while traveling down through the burrs and can sometimes clog up the teeth. It doesn’t hurt the grinder but it does require cleaning (which is tool-free!). Another downside for both machines is the fact that they run on DC power so it’s best if you have a spot in your kitchen to tuck away the power brick. I also made a kit that makes the gear pump a drop-in upgrade for other espresso machines, to reduce noise and add adjustable pressure. https://bit.ly/4fm0z0K The roughest part of this process were the moments midway through development where they weren’t working at all. When the grinder is just jamming itself instantly or the fourth factory in a row tells you the part you’re making is impossible or the pump is alternating between spraying water out the side and into your face and not pumping at all. And the default thought is “Of course it’s not working, if this was going to work someone else would have already made it like this”. The route you’ve taken is fundamentally different enough that there are no existing solutions to draw on. You’re basically feeling around in the dark for months on end, burning money, and then one day, every little cumulative change suddenly adds up to a tasty espresso. And it’s not perfect yet, but you at least can see the road ahead. Anyways, this is way more than I expected to write, thank you for reading!

Show HN: Kiln - Interactive LLM fine-tuning, dataset collab & synthetic data gen https://bit.ly/3ZxDNgE

Show HN: Kiln - Interactive LLM fine-tuning, dataset collab & synthetic data gen Hi HN! Excited to share a project I’ve been working on called Kiln AI! It solves what I’ve always found to be the hardest part of building AI products: products simply don’t have datasets, and datasets can’t keep up with product evolution. Product goals evolve, are hard to define, and new bugs emerge all the time. Kiln helps you build ML models for your product, from a collaborative dataset. For a bit of context: I’ve been building consumer AI products for a decade at Apple, my own startup, and MSFT. At its core Kiln is 3 things (so far): - Really great collaboration: Kiln datasets are designed to be shared/versioned in Git. We make it easy for the full team (PM/QA/subject-experts) to contribute directly, via super intuitive apps. With Kiln, when anyone on the team adds bugs/evals/goals, they go right into the dataset to be picked up in the next build. - Rapid fine-tuning: dispatch fine-tuning jobs for a range of top models (Llama 3.2, Mixtral, GPT 4o/4o-mini). It’s fine tuning in just a few clicks. - Synthetic data generation: our interactive data gen helps create large enough datasets for fine-tuning and evals. Build an initial training dataset, or use it to build out enough examples of a bug for the model fix it. It uses large models and heavy prompts (COT, multi-shot), which allows you to fine-tune smaller and faster models. The link here is to the new fine-tuning feature which just launched today. The demo shows starting a project from scratch, defining a task, generating synthetic training data, fine-tuning 9 models, and deploying them. It’s all very easy: 18 mins of active work, all in an intuitive UI. You can download the apps and follow the same process for your own product goals. I’d love to chat with folks building AI products, and offer any help I can (tools and/or guidance). Fire me a message at steve@getkiln.ai if interested. You can download our apps for Mac, Windows or Linux, or `pip install kiln_ai` for the library.

Show HN: Program a robot to solve a maze on a CPU emulator A little game I made to show off an old project. The functionality of the CPU is derived entirely from simulated logic gates. All the operations and control flow are based on the underlying properties of the logic gates, and changing their operation leads to corresponding changes in function. The original game code is all python and it runs in the browser using wasm/pyodide. Not very mobile friendly https://bit.ly/3Bq7ND4 December 8, 2024 at 06:53PM

Show HN: A Security-First Web Server in C with XSS, SQL Injection Protection https://bit.ly/3D7VY52

Show HN: A Security-First Web Server in C with XSS, SQL Injection Protection I built a high-performance web server in C that prioritizes security from the ground up. Key features: - XSS protection and SQL injection prevention built into the core - Rate limiting with IP tracking and automatic blocking - Comprehensive security headers (CSP, HSTS, CORS) - Multi-threaded architecture with connection pooling - Zero-copy file serving for performance - 100% test coverage with integration tests - Pure C99, no external dependencies beyond POSIX The goal was to create a web server that's secure by default and easy to audit (under 2000 lines of C). All security features are enabled out of the box with sensible defaults. GitHub: https://bit.ly/49sImx8 I am looking for feedback, especially on the security implementation and test coverage. The code is MIT-licensed. https://bit.ly/49sImx8 December 8, 2024 at 11:47PM

Show HN: Cut the crap – remove the AI bullshit from websites https://bit.ly/4isYmmO

Show HN: Cut the crap – remove the AI bullshit from websites I’ve spent a lot of time reading articles that promise a lot but never give me what I’m looking for. They’re full of clickbait titles, scary claims, and pointless filler. It’s frustrating, and it’s a waste of my time. So I made a tool. You give it a URL, and it tries to cut through all that noise. It gives you a shorter version of the content without all the nonsense. I built this because I’m tired of falling for the same tricks. I just want the facts, not a bunch of filler. What do you think? I’m also thinking of making a Chrome extension that does something similar—like a reader mode, but one that actually removes the crap that gets in the way of real information. Feedback welcome. https://bit.ly/4go7Lum December 8, 2024 at 11:59AM

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: 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: 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: 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

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
