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.

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 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.

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.

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.

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

Show HN: It took me 5() months to build a Plausible alternative https://bit.ly/41a0HNy

Show HN: It took me 5() months to build a Plausible alternative After months of using Google Analytics I realized only about 50% of people accepted my cookie-popup. I had months of incorrect data for my website. I started looking for alternatives and eventually found Plausible, which is great (and open-source). Problem is, I didn't feel like paying 9$ a month to see the amount of visitors on a website i didn't even earn anything on, it was just a hobby project. Eventually I started making my own web analytics. Which actually isn't that hard. It took me about a month of working on my spare time every now and then. Being GDPR compliant basically means to not save any personal identifiers. At first I thought it would be easy since something like a public IP adress can't count as a personal identifier right? I was very wrong. How it works: When a user visited my website I saved the IP and Header for 24 hours. Then if they visited again I checked the combination of IP and Header against the ones saved in my DB. If they were the same I simply added 1 view to my data. If they weren't the same I added 1 unique daily user and 1 view. That's in short how it works. A few weeks later I realized if I had this problem then other would also have it. So I started working on Simplytics.dev. I had to do a lot of new stuff and re-build my code from the ground-up twice. Small things like OAuth was completely new to me and took up a lot of time. But eventually I got here and just launched something that with the knowledge I have today wouldn't even take a third of the time recreating today. It's my first real "Launch" and it feels really good finally creating something AND publishing it. Instead of a montly fee I opted to make it a pay-once service. Right now it's priced at 49$ but I'll see how it works out. If you got any questions on how it works Id love to answer them. November 25, 2024 at 04:35PM

Show HN: myphotos.site – Google photos to a website in 60 seconds Hey HN! My friend and I love taking pictures on our phones, and we were looking for a super simple way to share them with the world. Google Photos albums are nice, but the result isn't slick enough and lacks customization options (embed, custom domain). That's why we built myphotos.site - a micro SaaS that allows anyone to create a slick, minimal gallery website from Google Photos. Galleries can be iframe-embedded for those looking for full customization. One thing we haven't solved yet - many Google Photos users (myself included) do not have images pre-organized in albums, so the fact that technically it takes 60 seconds to build a website doesn't take into account that you have to spend time picking the right images. Would love to some feedback/ideas from hobbyist photographers here! https://bit.ly/417vj1V November 28, 2024 at 12:02PM

Show HN: A library of tree search algorithms for AI agents https://bit.ly/3VcTEjo

Show HN: A library of tree search algorithms for AI agents Hi HN, I built this to address what I see as the fundamental problem with ReAct-style agents: compounding errors. Even a small mistake made early enough in the loop can snowball and ruin the final output. But with search, agents can look multiple steps ahead and backtrack before committing to a particular trajectory. This has already been shown in a few papers to help agents avoid mistakes and boost overall task performance, but there's no easy way to actually build these kinds of agents. So that's why I made this framework. I believe search will eventually become table stakes for building agents as inference gets faster and cheaper, and this library is the first (and only) way to get that performance boost easily. – Jonathan https://bit.ly/4119Jwh November 26, 2024 at 03:20PM

However, Liquid is a terrible language for data-mangling, and simple filtering/sorting/merging can become very annoying. So I wrote a Jekyll SQLite plugin that lets you use the same data interface in Jekyll/Liquid, but backed by a SQLite file(s). It gives you the simplicity of the Baked Data pattern[2], and the flexibility of using SQL for data-wrangling, within a static site generator. As a demo, I took the northwind dataset, and generated a site[3] with a few sample queries[4]. It demos both site-level, and page-level queries alongside data-pages generator to generate a page for every product/category/customer. I've been using this across a few sites in production for almost a year, looking for feedback on usage semantics and feature suggestions.

Show HN: I Built a Lightweight Nutrition Tracker for the iPhone https://bit.ly/4fDNcde

Show HN: I Built a Lightweight Nutrition Tracker for the iPhone Hey HN, I was overweight in college and started my weight loss journey using an app called MyFitnessPal. Tracking calories not only helped me lose weight but also taught me a lot about nutrition and helped establish healthy eating habits that continue to benefit me. However, I’ve always been frustrated by the existing nutrition tracking apps. Many are slow and bloated, lack accurate nutrition data, or don’t respect user privacy. I wanted to build something that I’d love using myself. A few things that make FitBee stand out: * Fast, lightweight and to the point - The app is just about tracking your nutrition and makes that front and center. I've tried to make things that you do often as simple as possible (e.g., log yesterday's breakfast). * Robust Apple Health support - You can read/write data to Apple Health. I wear an Apple Watch so it's great for getting the energy burned through exercises. * Accurate nutrition data - The nutrition data is sourced from the USDA dataset and nutrition labels off the packages. I also spent effort adding east asian foods (e.g. things you get at 99 Ranch or Weee) to the database, since those were hard to find/track in other apps I've tried. * Photo Logging - You can take a photo of a food and get an estimate of the calories and macros. It's not 100% accurate but it's been super helpful for me when eating at a restaurant that doesn't have published nutrition info. * Recipe importing - You can pretty much point any recipe at the app and it'll import the ingredients and generate nutrition information for you. As I got more into fitness, I started to cook more so this has been super helpful. * No Ads - The app is monetized via a subscription. * Subscription - Most of the features are free, but there are a few which require a monthly or annual subscription ($4.99/month or $39.99/year). You can try FitBee here: https://ift.tt/V1uocZJ . I'd love your feedback! https://apple.co/3V6Psla November 25, 2024 at 05:51AM

Show HN: AI bot that automatically processes unstructured documents https://bit.ly/4eI1458

Show HN: AI bot that automatically processes unstructured documents Hi HN! We’re excited to share what we’ve been working on—a bot that automates the tedious task of processing unstructured documents from emails and entering them into ERPs. After many iterations, we’ve achieved 99.8% accuracy in extracting and mapping data from invoices, POs, and other documents. One surprising takeaway from this journey: building the AI was only 10% of the challenge! The real work came from handling edge cases, integrating seamlessly with various ERPs, and creating a reliable pipeline for real-world documents with messy formats. We’d love your feedback, thoughts, or questions about how we built this, the challenges we faced, or anything else. Let us know what you think!

I just launched llms.txt Generator, a tool that transforms any website into a clean, structured text file optimized for feeding to LLMs. You can learn more about the standard at https://bit.ly/3Ziwc6J . Here’s how it works under the hood: 1. We use Firecrawl, our open-source scraper, to fetch the full site, handling JavaScript-heavy pages and complex structures. 2. The markdown content is parsed and then the title and description are extracted using GPT-4o-mini. 3. The everything is combined and the result is a lightweight llms.txt file that you can paste into any LLM. Let me know what you think! https://bit.ly/3V3thw8 November 21, 2024 at 08:33PM

Show HN: I built a real professional network because was sick of following/DMing Hey everyone, I have been doing Indie Hacking for almost 2 years. I was sick of following people on social media or DMing and calling it networking. So, I built a network/platform where professionals meet with fellows via scheduled video calls. We as a community believe that this is a better way as an initial contact than follows and direct messages. Our platform is open for free, early access, currently. Feel free to check us out at https://bit.ly/3V5dDAe and if our mindsets match, you may join us at https://bit.ly/3YY8xHj Whom is it best for? It's perfect for entrepreneurs, indie hackers, developers, designers, social media marketers and more. Whether you're just starting out or looking to expand your network, you are welcome. What would be the gain? Strong network is our need as a member of the community. We need an audience for our products, clients for our services and professionals to hire them or make them hire us. First time meeting people in need would work much less than asking people already in our network that we build via more than just following each other or direct messages. And this is the network where you meet people face to face without immediate requests/needs. https://bit.ly/3Zfws6q November 22, 2024 at 04:40AM

Show HN: PDF2MD – Rust+Redis+ClickHouse+VLLM conversion pipeline for PDFs If you just want to use it, try here - https://bit.ly/4fBCowo . I think the LLM's are astoundingly good at converting complex powerpoint style infographics. I wouldn't normally think folks on HN would find this interesting as the general concept has been posted about already in the past few months. We were heavily inspired by Zerox[1]. However, the stack we went with was fun and over-engineered which is more likely to create interesting discussion. We use all the same tools at Trieve (our main product), but wanted to see if they would be a good fit for something that needed to get built in a tighter timeline and we think they were! Took us 2 weeks to get this setup end-to-end and it's by no means complete (see roadmap in linked README). However, it's cool that a relatively cookie cutter web service like this can be created with pure open-source dependencies and non-standard Rust tooling so quickly.

Show HN: Video editor app that generates FFmpeg commands https://bit.ly/3V4o3Af

Show HN: Video editor app that generates FFmpeg commands Hello Friends, I have built a new video editor app that generates ffmpeg commands to get the edited video. This gives you flexibility to use it in scripts etc. for your video editing workflows and makes editing tasks smooth by letting you visually adjust video elements that are difficult to adjust in commandline. Demo is here - https://www.youtube.com/watch?v=KSvazNBEfTc Link is here - https://bit.ly/3AUbIru Features are - video, image, text editing - adjustable timeline and layers - adjust position, size , alignment, font size color, borders etc. - quick info of image, video files - preview player to get the idea of edited video with play, pause, seek. Limitations are - Audio files(mp3) are currently not supported though audio inside mp4 will work - player is not frame accurate it just gives u close enough approximation. - file paths are not supported due to browser's security limitations. - I have only tested happy path so there would be many bugs but it should work for simple tasks Others - Completely free - No registration/login etc. - Works online does not requires any installation - Works offline after first load - Works locally does not requires server Background is i generally have one off video tasks and i don't mind using ffmpeg for it but recently i had to create a bunch of product videos and it was difficult to get text etc. right on commandline, i tried kdenlive and openshot as well but couldn't figure out how to something simple like adding a logo and text to it(i guess i am dumb) so i created this new app to suit my workflow https://bit.ly/3AUbIru November 21, 2024 at 07:13PM

Show HN: Bike route planner that follows almost only official bike trails https://bit.ly/4eW8bah

Show HN: Bike route planner that follows almost only official bike trails Hey guys, I built a route planner that is mostly focused on bike touring and using existing bike infrastructure. For each request you're shown what bike tracks/trails your route uses and can further explore them by showing them on map or going to the official trail route. The main idea for the app is to have a friendly and easy to use planner that would make heavy use of official bike trails data (mainly from OpenStreetMap) and make it easy to plan a longer trip using the best possible bike routes out there. Currently the app only works for the Euro region but I'm planning to add North America very soon and then rest of the world. Technical overview: Route finding - Graphhopper sitting in a docker container on a Hetzner server somewhere in Germany. It has 38 GB of graph data(Europe) loaded into RAM for a fast graph traversal. Web App - Next.js 14 with Typescript, backend on the newest version of .NET Map tiles - right now I'm using MapTiler their free tier but planning to switch to my own home server soon and host the maps on it. https://bit.ly/3CEVuDd November 20, 2024 at 09:23PM

Show HN: Browser-based website builder powered by LLMs I wanted to share what I've been working on - it's a AI site builder that runs in the browser powered by WebGPU and OnnxRuntime-Web. I have got the following all working to varying degrees: - text to code generation - image to code generation - microphone to text to code generation If you are on Mac for instance, it will interface directly with your GPU to power the LLM interface. It only requires downloading the models, and then everything after that is offline. It's not even close to as powerful as Claude or ChatGPT, but I like the idea of having the LLM run directly on your machine. I just did this for fun, but I am looking for a new role if anyone's hiring - https://bit.ly/3CxhuzU ! More technical insight: - I also got the Typescript / React app to compile itself in the browser via a service worker https://bit.ly/3Z0M1gS but took it offline due to some oddities with service workers. - A lot of the new speech models are a lot better than anything built into your phone / computer. I wonder when more computers will have them built in. - I added a CSP to the iframe only because I was worried about spamming sites since I update the iframe anytime a new token comes in. So if you have an image on the page it will get reloaded every time the iframe is updated. Otherwise there would be no reason for it. https://bit.ly/48VHWiJ November 19, 2024 at 09:24PM

Show HN: Nova JavaScript Engine https://bit.ly/4fNTlDm

Show HN: Nova JavaScript Engine We're building a different kind of JavaScript engine, based on data-oriented design and willingness to try something quite out of left field. This is most concretely visible in our major architectural choices: 1. All data allocated on the JavaScript heap is placed into a type-specific vector. Numbers go into the numbers vector, strings into the strings vector, and so on. 2. All heap references are type-discriminated indexes: A heap number is identified by its discriminant value and the index to which it points to in the numbers vector. 3. Objects are also split up into object kind -specific vectors. Ordinary objects go into one vector, Arrays go into another, DataViews into yet another, and so on. 4. Unordinary objects' heap data does not contain ordinary object data but instead they contain an optional index to the ordinary objects vector. 5. Objects are aggressively split into parts to avoid common use-cases having to reading parts that are known to be unused. If this sounds interesting, I've written a few blog posts on the internals of Nova over in our blog, you can jump into that here: https://bit.ly/40YfudQ https://bit.ly/40RuAlr November 18, 2024 at 12:07AM

Show HN: Lyceum – An MMO game built with Zig and Erlang https://bit.ly/48JtwSx

Show HN: Lyceum – An MMO game built with Zig and Erlang Hey HN, this is a small project myself and closer friends have been building on our free time ( https://bit.ly/3YM6Ts2 ), it finally reached 0.1.0, we are open to feedback! The original idea was to experiment with Zig + Raylib, eventually we wrote a small server in Erlang as well. We started by first interacting with Erlang via its C bindings, but this eventually led to some of us to prototyping our own tooling to better integrate Zig types with Erlang, we called such tool "zerl" as its avaliable here https://bit.ly/3YM6TZ4 . Most of the developers are NixOS users, so the tooling heavily relies on Nix as well, including a Postgres running our devshell as well. https://bit.ly/3YM6Ts2 November 5, 2024 at 05:45PM

Show HN: LLM driven OS to execute network security exploration agents https://bit.ly/3O1S9jV

Show HN: LLM driven OS to execute network security exploration agents I made this thing where LLM works like a tiny OS kernel - it plans tasks and runs different agents. Right now it's doing security stuff (poking at networks, checking SSL, testing APIs) with WebGoat as a playground. The ultimate goal is to ask it "find vulnerabilities in XYZ" and see it orchestrate its own tools, backtrack, try different approaches, etc. The cool part is the LLM doesn't just blast out a bunch of tokens - it plans, reasons and executes tasks step by step during inference. Currently playing with security agents but you could plug in anything really. Would love getting you to play with it and maybe add an agent or two. https://bit.ly/3NZXkAK November 10, 2024 at 03:02AM

Show HN: SICP-VSCode I am sharing an opinionated configuration for VS Code that should suffice to work through Structure and Interpretation of Computer Programs (SICP). I have owned SICP for a decade or more and am giving it another go. I (re)started it last weekend using the DrRacket editor, which is fine, but I spend most of my time in vs code. It was a jarring to use another editor. So, in an evening of delightful bikeshedding, I now have a setup that should let me work through SICP in vs code. I thought I'd share this in case someone else is interested or has any feedback. This is a barebones configuration with a lightly tested installation script that works on my machine! I wanted to avoid installing a bunch of vs code extensions and was able to get this working with only a single extension to add scheme support to vs code.

Show HN: RL Agent that can auto-optimize your LLM prompts Hey everyone! Along with my team, I've developed a reinforcement learning system that automatically optimizes LLM prompts, complete with a visualization feature to track both prompt structure and learning progress over time. Take a look here: https://bit.ly/3YX9Ozo... Check out our website too: https://bit.ly/48Mo9lB In terms of how this visualization works: The RL Prompt Optimizer employs a reinforcement learning framework to iteratively improve prompts used for language model evaluations. At each episode, the agent selects an action to modify the current prompt based on the state representation, which encodes features of the prompt. The agent receives rewards based on a multi-metric evaluation of the model's responses, encouraging the development of prompts that elicit high-quality answers.

Show HN: Firecrawl-Simple – Stable fork of Firecrawl optimized for self-hosting https://bit.ly/40z3lfu

Show HN: Firecrawl-Simple – Stable fork of Firecrawl optimized for self-hosting Firecrawl Simple is a stripped down and stable version of firecrawl optimized for self-hosting and ease of contribution. The upstream firecrawl repo contains the following blurb: >This repository is in development, and we're still integrating custom modules into the mono repo. It's not fully ready for self-hosted deployment yet, but you can run it locally. Firecrawl's API surface and general functionality were ideal for our Trieve sitesearch product, but we needed a version ready for self-hosting that was easy to contribute to and scale on Kubernetes. Therefore, we decided to fork and begin maintaining a stripped down, stable version. Fire-engine, Firecrawl's solution for anti-bot pages, being closed source is the biggest deal breaker requiring us to maintain this fork. Further, our purposes not requiring the SaaS and AI dependencies also pushes our use-case far enough away from Firecrawl's current mission that it doesn't seem like merging into the upstream is viable at this time. https://bit.ly/3NVAdr9 November 6, 2024 at 12:18AM

Show HN: Open-Source HTTP Interceptor – Capture, Modify, Run Requests in Browser https://bit.ly/3O16XPD

Show HN: Open-Source HTTP Interceptor – Capture, Modify, Run Requests in Browser Hey HN, I recently built an open-source HTTP interceptor called Relay, which works as a Chrome extension for capturing, modifying, and replaying HTTP requests directly in your browser — no account needed. How it works: Relay lets you capture requests as they happen, modify parameters, headers, or body content, and replay them on the fly. You can customize or debug network requests quickly without needing an external tool or complex setup. Key features: - Simple setup: Install the extension and start a session to capture requests. You can filter by URLs and methods. -Request modification: Make quick edits to any part of the requests for debugging or testing. - Copy as cURL: Easily copy requests as cURL commands to use elsewhere if needed. - Replay functionality: Re-run requests with modified data or headers and see the results in your browser. - Local, no account needed: All interactions are handled locally in your browser, so you maintain privacy and control over your data. I built Relay to make tasks like testing API integrations, troubleshooting network calls, and experimenting with client-side requests easier. Originally, I made it for myself because I wanted a faster way to look at and edit network requests without constantly switching between my browser and other tools. After seeing how useful it was, I decided to make it open-source for anyone who would find it useful. Here's the GitHub repo: https://bit.ly/3NW7PFw Would love to hear your feedback and suggestions! https://chromewebstore.google.com/detail/relay-–-intercept-modify/kilmhgoembjiamcmcbecekdonljjiolg November 5, 2024 at 11:48AM

Show HN: CMD+C – Instant Grammar Correction Across All Apps for macOS https://bit.ly/3Cava3H

Show HN: CMD+C – Instant Grammar Correction Across All Apps for macOS Hey HN! Here is my simple native macOS app for correcting grammar — CMD+C. I'm a non-native English speaker working in English-speaking teams, and I care about how my Slack messages and other communications come across. Frustrated with switching between grammar tools, apps that don't support some input boxes, and endless copy-pasting, I built CMD+C — a simple macOS app that corrects grammar on the fly in any app, with just a triple-click. Features: 1) Triple-click "⌘+C" to correct any selected text instantly, no matter where you're typing. 2) Use your own API key (OpenAI, Anthropic) or access premium corrections with our plan. 3) View correction history with explanations from GPT why it was corrected and export JSON/CSV if needed. How it works: 1) Intercept triple "⌘+C" shortcut in macOS 2) Process text with LLM (OpenAI, Anthropic) with custom prompt 3) Replace selected text with the corrected version and save it to better understand why and how it was corrected CMD+C was built in 7 days, is free to use, and I plan to share the source code later this month. I've never built anything before, so I'd love your feedback - let me know what you think! Hope someone finds it useful! https://bit.ly/3YBykF5 November 4, 2024 at 12:03AM

Show HN: Holos – Configure Helm and Kustomize Holistically with Cue https://bit.ly/4hy30Q4

Show HN: Holos – Configure Helm and Kustomize Holistically with Cue Hi HN! I’m excited to share Holos, a Go command line tool I wrote to make it easier to manage a platform built on Kubernetes. Holos implements the rendered manifests pattern as a data pipeline to fully render manifests generated from Helm, Kustomize, or CUE in a holistic way. At the start of the pandemic I was migrating our platform to Kubernetes from virtual machines managed by Puppet. My primary goal was to build an observability system similar to what we had when we managed Puppet at Twitter prior to the acquisition. I started building the observability system with the official prometheus community charts [1], but quickly ran into issues where the individual charts didn’t work with each other. I was frustrated with how complicated and difficult to configure these charts were. They weren’t well integrated, so I switched to the kube-prometheus-stack [2] umbrella chart which attempts to solve this integration problem. The umbrella chart got us further, as long as we didn’t stray too far from the default values, but we quickly ran into operational challenges. Upgrading the chart introduced breaking changes we couldn’t see until they were applied, causing incidents. We needed to manage secrets securely so we mixed in ExternalSecrets with many of the charts. We decided to handle these customizations by implementing the rendered manifests pattern [3] using scripts in our CI pipeline. These CI scripts got us further, but we found them costly to maintain. Teammates needed to be careful to execute them with the same context they were executed in CI. We realized we were reinventing Hiera to manage a hierarchy of helm values.yaml files to inject into multiple charts. At this point I started looking for a more holistic solution to this problem of integrating multiple charts together. We saw the value in the rendered manifests pattern, but we couldn’t find an agreed upon implementation. We built a Go command line tool to implement the pattern as a data pipeline. I’d been thinking about the comments from the Why are we templating YAML? [4][5] posts and wondering what an answer to this question would look like. The Go command line tool was an incremental improvement over the CI scripts, but we still didn’t have a good way to handle the data values. We were still templating YAML which didn’t catch errors early enough. It was too easy to render invalid resources Kubernetes rejected, causing deployment problems. I searched for a solution to manage helm values, something like Hiera which we knew well from Puppet, but not hierarchical because we knew it was important to trace where config values came from in an outage. A few HN comments mentioned CUE [6], and an engineer we worked with at Twitter used CUE to configure Envoy at scale, so I gave it a try. I quickly appreciated how CUE provides both strong type checking and validation of constraints, unifies all configuration data, and provides clarity into where values originate from. Take a look at Holos if you’re looking to implement the rendered manifests pattern or can’t shake that feeling it should be easier to integrate third party software into Kubernetes like we felt.
