Show HN: Pass in data to Visa and cut your credit card fee by 50% Here's how your business can save up to 50% on credit card fees. Credit card interchange fees are expensive. These fees are what the credit card networks like Visa and Mastercard charge the merchant (you) whenever your customer swipes their card. Stripe or your payment processor passes these fees onto you. To incentivize data collection, Visa and Mastercard lower your fees whenever you pass in transaction data like zipcode, sales tax amount, invoice amount, customer address, itemized purchased services or goods, and the list goes on. This is called L2 and L3 data, and you can pass this into Stripe (or your payment processor) to lower your credit card fees. Parsing invoices manually to provide L2/L3 data to Visa is a pain. But with Trellis, you can do this automatically within seconds for any invoice. Watch how we do it here: https://ift.tt/6nmUCHz... If you’re a business and you accept credit cards, you can cut your credit card processing fee in half. https://ift.tt/sAQpfFb June 28, 2024 at 02:30AM

Show HN: I built an indie, browser-based MMORPG I've been working on an MMORPG that is now in alpha as a solo developer. Here are the major open source technologies that I use: Blender - 3D modeling software for creating the overall environment and every game object. I've gotten a lot of CC and Public Domain assets from https://poly.pizza GLTF - I export assets from blender to the GLTF asset format JSON - I write a JSON config for every game object that describes things like its name, its interactions, its collisions, etc. Node.js exporter - I iterate over the environment and every asset to create a scene hierarchy. I use gltf-transform for processing all GLTF files, compressing them, removing redundancies, etc. Node.js server - Uses express and socket.io to process game state updates. It keeps track of every client's game state and issues delta's at each game tick (currently 600ms). The client can send interactions with different objects. The server validates those and updates the game state accordingly. HTML/CSS/JavaScript/Three.js client - I use regular web technologies for the UI elements and three.js for the 3D rending on the browser. The client is responsible for rending the world state and providing the client with different interactions. All code is written in JavaScript which means less context switching. Performance seems to be good enough, and I figure I can always optimize the server code in C++ if necessary. I am currently running two cheap shared instances but based on my testing, they can likely support about 200 users each. This is a low-poly browser based game so it should be compatible across many devices. The data a user needs to download to play, including all 3d assets, is approximately 2 MB, even though there are hundreds of assets. Overall, it's been a fun project. Web development and open source software have progressed to the point that this is no longer an incredibly difficult feat. I feel like development is going pretty well and in a year or so there will be plenty of good content to play. https://ift.tt/t5qKpkb June 26, 2024 at 11:23PM
Show HN: Voice bots with 500ms response times Last year when GPT-4 was released I started making lots of little voice + LLM experiments. Voice interfaces are fun; there are several interesting new problem spaces to explore. I'm convinced that voice is going to be a bigger and bigger part of how we all interact with generative AI. But one thing that's hard, today, is building voice bots that respond as quickly as humans do in conversation. A 500ms voice-to-voice response time is just barely possible with today's AI models. You can get down to 500ms if you: host transcription, LLM inference, and voice generation all together in one place; are careful about how you route and pipeline all the data; and the gods of both wifi and vram caching smile on you. Here's a demo of a 500ms-capable voice bot, plus a container you can deploy to run it yourself on an A10/A100/H100 if you want to: https://ift.tt/gva2oRE We've been collecting lots of metrics. Here are typical numbers (in milliseconds) for all the easily measurable parts of the voice-to-voice response cycle. macOS mic input 40 opus encoding 30 network stack and transit 10 packet handling 2 jitter buffer 40 opus decoding 30 transcription and endpointing 200 llm ttfb 100 sentence aggregation 100 tts ttfb 80 opus encoding 30 packet handling 2 network stack and transit 10 jitter buffer 40 opus decoding 30 macOS speaker output 15 ---------------------------------- total ms 759 Everything in AI is changing all the time. LLMs with native audio input and output capabilities will likely make it easier to build fast-responding voice bots soon. But for the moment, I think this is the fastest possible approach/tech stack. https://ift.tt/gva2oRE June 27, 2024 at 03:21AM
Show HN: The Tomb of Nefertari [QV 66] Guided Virtual Tour I 3d scanned the Tomb of Nefertari and am building this guided virtual tour, trying to bring in photogrammetry of artifacts that I've made at various museums. It crashes sometimes still on mobile devices. I wasn't able to take photogrammetry photos of the artifacts from the tomb in the Museo Egizio in Turin because they were traveling while I was there (and now the museum is closed to install a new roof anyhow), so I tried to include comparanda from other museums where I had scanned artifacts. I tested the same dataset with 3d Gaussian Splatting but that had lower resolution results for great complexity in frontend code and reduced performance on older devices. [3DGS tour: https://ift.tt/u5wpmcP... ] Moving forward, if anyone's working on the same idea, I didn't find a good path to monetization through web-based 3d content, so I'll take the high resolution photogrammetry of spaces into Unreal and switch to desktop and headset builds. For the distribution advantage of web-based 3d content, I'm hoping to test next a desktop or VR build that may be easier to sell to sustain my work. https://ift.tt/PGDw13t June 25, 2024 at 08:18PM
Show HN: AI-Generated Tables for a Steampunk City I recently embarked on a creative experiment where I used ChatGPT to craft an elaborate steampunk story.

Show HN: Tsellm: Interactive SQLite shell with LLM support Hello HN, While browsing the Python docs yesterday, I discovered that the latest 3.12 version has added support for a `python3 -m sqlite3` interactive shell. I looked into the source code, and its implementation was simple, giving me an idea: Why not hook the beautiful llm library by simonw into such an interactive shell, and thus have direct LLM support in SQLite? Without writing a C extension, build a shared object and all that fuss. Well, now you can `pip install tsellm` and do just that. demo gif: https://ift.tt/eFWpk4q... https://ift.tt/6DBGpK9 June 23, 2024 at 11:45PM
Show HN: Online OPML editor to manage subscription lists I made a small online editor to manage OPML[1] files easily. There are a lot of smart online editors for formats like JSON, but while OPML is supported by most subscriptions services, the experience of editing/managing it is poor outside of what each platform support. The pain of managing the file independently increases as the size of the OPML file grow larger. It's rather simple at the moment but the goal is to provide shortcuts for common desired tasks to make the experience of editing OPML much smoother and streamlined. The editor is a static website that runs locally in your browser, it doesn't require an account, nor do any tracking.

Show HN: Feedback on Sketch Colourisation Hi I am looking for some feedback on our new project "Sketch Colourisation". The envisioned UI and objectives are -- * An artist should have greater control on how to colour a sketch. While a text-to-image model lacks this fine-grained control, a per-pixel colourisation pipeline makes sketch colourisation a laborious process with high-entry barrier. * What if an artist only draws a mask for a local region and specifies the colour palette for that local region? Then a neural network figures out how to colour the overall sketch -- while maintaining those local colour palette. [I would really like a feedback if the above UI (i.e., mask and local colour palette) makes sense to users/designers. As researchers, we often have the wrong idea of what is desired by end-users.] * On the exact implementation of the above concept, we designed a no-training based neural network framework -- and also make sure it runs on a Nvidia 4090. In other words, I will try to avoid any expensive training or inference -- which defeats the purpose of being useful to people (not just some research labs). * Note, I am not so bothered about the exact implementation (or whether it is "novel") -- as long as it is useful. * A shameless advertisement: The codebase ( https://ift.tt/9n0Bg4S ) is MIT License. It is no way near to being useful to people -- but I would really like to pursue this direction and your feedback/criticism will be immensely helpful.

Show HN: Synapse – TypeScript Toolchain for Cloud Apps Hey all, I've been working on a developer tool based on my experiences with working on cloud applications. What I've created is basically Node.js + TypeScript + Terraform all combined into a single tool, Synapse. I like to think of Synapse as a "compiler for distributed systems", though it can also be used as a build tool for any JavaScript/TypeScript app. In fact, Synapse is built with Synapse! I recently open-sourced the bulk of the codebase, but a lot of work is still needed to make it easy to contribute. If anyone is able to try it out and give me feedback, it would be hugely appreciated! There's not many documented features at the moment, but I think what I have now is at least enough to get a basic idea of what Synapse can do. https://ift.tt/XKRVtCQ June 22, 2024 at 03:51AM
Show HN: I made a demo for my project management tool Hey Hackers, Last time I posted alot of the comments were asking about the posibility for a demo and maybe more reasoning on why someone should use the service. I have tried to implement some more things into the basic tier so that out of the box, the service is more unique with its use of AI. Anyway, there is now some new AI features as well and I've improved the existing features to ensure they have the right level of accuracy and creativity. Enjoy, Dan https://ift.tt/U7Ee4zl June 22, 2024 at 03:37AM
Show HN: AI Data Analyst Hey HN, Michael and Alexey from Narrative BI here. Background We've been working on Natural Language Query tools for quite some time. Back in the pre-LLM era, we launched a natural language to SQL startup called FriendlyData. It was later acquired by Service now where we integrated it into the Now Intelligence platform. Then we started Narrative BI with the thesis that business users like marketers don't always know how to ask data questions, so our goal was to build a product where data insights are generated proactively, before users even ask questions. Evolution The general dynamics of Generative AI going mainstream created an interesting opportunity. We still believe that the future of BI lies in proactive analytics and easy data integrations. However, with increased AI awareness, we've seen a lot of interest from our users in natural language capabilities, so we decided to take it to the next level. Why don't just use ChatGPT? The problem with ChatGPT and other chat-based LLM tools that they hallucinate a lot. ChatGPT answers look plausible so most of users don't bother to verify if the answers match the actual data. However our research shows that ChatGPT hallucination rate is 47% for more or less complex data sets, such as Google Search Console data, for example. For business data analysis accuracy is the key as wrong answers can lead to misinformed decisions. Another limitation is data integration. AI data analyst comes with pre-built data integrations, so you can easily connect your data sources such as GA4, Google Ads, Google Search Console, FB Ads, Hubspot and Salesforce. More data sources coming soon and we're also doing custom integrations for enterprise. We're here to answer your questions and look forward to your feedback! https://ift.tt/juCrdag June 21, 2024 at 12:30AM
Show HN: Billard – Generate music from ball collisions in 2D space Hello HN! Here's Billard. It combines music and physics into a unique creative tool, as I explore various unconventional methods for generating music. Most traditional music composition tools revolve around the idea of a repeatable pattern. Billard is a webapp that never repeats itself. It generates music automatically based on the collisions of balls in a 2D space. Collisions trigger notes (or chords) in a given key. One can add balls or move them (y-position is pitch); the app remembers its state between reloads; or it can be reset with the 'init' button on the top left. Gravity can be adjusted in real time to change the behavior of the balls. It owes a lot of inspiration to Brian Eno and Erik Satie (inventor of musique d'ameublement , or "furniture music"). Some may think the lack of pattern makes it not musical enough -- but this lets it be listened to —and watched— for a while without boredom. The webapp is made using plain JavaScript. (All SVG icons were made 'by hand'.) It uses Tone.js only for triggering piano samples. Beyond piano, it's MIDI-enabled and works well at slow speed with haunting, dark synth sounds. Hope you like it! https://ift.tt/H1Pxibr June 18, 2024 at 10:15PM
Show HN: Token price calculator for 400+ LLMs Hey HN! Tokencost is a utility library for estimating LLM costs. There are hundreds of different models now, and they all have their own pricing schemes. It’s difficult to keep up with the pricing changes, and it’s even more difficult to estimate how much your prompts and completions will cost until you see the bill. Tokencost works by counting the number of tokens in prompt and completion messages and multiplying that number by the corresponding model cost. Under the hood, it’s really just a simple cost dictionary and some utility functions for getting the prices right. It also accounts for different tokenizers and float precision errors. Surprisingly, most model providers don't actually report how much you spend until your bills arrive. We built Tokencost internally at AgentOps to help users track agent spend, and we decided to open source it to help developers avoid nasty bills. https://ift.tt/aOHfM5p June 18, 2024 at 01:14AM

Show HN: b2v.xyz – Protection against impersonation attacks Hi HN, I’m the founder of https://b2v.xyz , a service that protects organizations against impersonation attacks. The problem I’m trying to solve stems from the following observation: while end-user authentication methods are becoming more advanced as cybersecurity evolves, organizations aren't experiencing the same improvements when we reverse the roles, i.e. when organizations authenticate themselves to their users. This imbalance leaves a gap in secure communications that B2V aims to close. Bad actors have countless ways to pose as trusted entities — through phishing, smishing, vishing, and more. These catchy terms may sound trendy, but the technology to combat them often lags behind. While some larger companies do offer some customised solutions such as in-app notifications, most approaches are still reactive, such as updating email filters after an attack is detected or requesting takedowns of fake domains long after the damage is done. It's surprising that more proactive measures aren't in place, especially considering the serious consequences of these impersonation attacks. How B2V tackles this problem: - Mutual authentication: During critical communications, an organization can initiate an authentication session and share it with a user via a unique URL. When the user opens it, the organization provides a one-time password that the user can verify. These single-use ephemeral sessions also protect against man-in-the-middle attacks, ensuring that the person you're communicating with is truly who they claim to be. This could also be described as *conversational authentication*. - Digital signatures: Prove the authenticity and integrity of information linked to your organization with public-key cryptography. This is especially useful for verifying that text or links posted on platforms/media outside of your control — such as job boards, paper invoices, forums, or messages — truly come from a trusted entity. For example here's the signature of this post's URL: https://b2v.xyz/b2v_/XHEbx8NdqjTF50?s=https://news.ycombinator.com/item?id=40699265 - Verified online identities: Organizations can link their online identities, similarly to the way Keybase does it. For instance, here's the proof of ownership of this HN account: https://b2v.xyz/b2v_/NMiMMr9KWov6oE?s=hn:b2v - Privacy by design: this system respects your privacy by never tracking or storing plaintext identifying information, only digests and signatures. - For deeper integrations, an API is also available. Could this be useful for machine-to-human or machine-to-machine communications, such as chatbots or multi-agent LLMs? Any feedback would be greatly appreciated, especially about my assumptions! Feel free to check out the docs ( https://docs.b2v.xyz ) and ask me anything. Thanks! https://get.b2v.xyz/ June 17, 2024 at 12:33AM
Show HN: Alpha Demo of NotePad.ai (open source) Hi all, I threw together a small prototype I am calling “Notepad.ai”. A new take on UIs for interacting with LLMs. While I enjoy using LLM’s in the chat format I wanted to see what it would be like to do it in a more long form style. It let’s you write in a pretty free form, much like Window’s Notepad, but you can choose to hit ctrl+[ to analyze the text with a preset prompt of your choosing. It has a few other small features.

Show HN: 100% open-source voice assistant – as a HAL9000 It started in 2018 with my first 3D printer and some openscad designs - just something that looks like a HAL9000 (and had a controlled red LED for the visuals) - it ended up being a full software-project...that hasn't ended yet. But: it is at a (quality-)point at which I am OK with putting it up on stage. My project goals: A digital voice-assistant that is... - actually usable (response times, error rates, ...) - performs everything on-device ("look ma, no cloud") - is entirely Free/Libre Open-Source-Software - is as-easy-as-possible to build I consider all four goals to be accomplished even at this ~90% stage of the project. If you just want to get some quick impressions, check out the "Demos" (video-)page in the github wiki (prominently linked in the README in the github repo).

Show HN: Paramount – Human Evals of AI Customer Support Hey HN, Hakim here from Fini (YC S22), a startup focused on providing automated customer support bots for enterprises that have a high volume of support requests. Today, one of the largest use cases of LLMs is for the purpose of automating support. As the space has evolved over the past year, there has subsequently been a need for evaluations of LLM outputs - and a sea of LLM Evals packages have been released. "LLM evals" refer to the evaluation of large language models, assessing how well these AI systems understand and generate human-like text. These packages have recently relied on "automatic evals," where algorithms (usually another LLM) automatically test and score AI responses without human intervention. In our day to day work, we have found that Automatic Evals are not enough to get the required 95% accuracy for our Enterprise customers. Automatic Evals are efficient, but still often miss nuances that only human expertise can catch. Automatic Evals can never replace the feedback of a trained human who is deeply knowledgeable on an organization's latest product releases, knowledgebase, policies and support issues. The key to solve this is to stop ignoring the business side of the problem, and start involving knowledgeable experts in the evaluation process. That is why we are releasing Paramount - an Open Source package which incorporates human feedback directly into the evaluation process. By simplifying the step of gathering feedback, ML Engineers can pinpoint and fix accuracy issues (prompts, knowledgebase issues) much faster. Paramount provides a framework for recording LLM function outputs (ground truth data) and facilitates human agent evaluations through a simple UI, reducing the time to identify and correct errors. Developers can integrate Paramount with a Python decorator that logs LLM interactions into a database, followed by a straightforward UI for expert review. This process aids the debugging and validation phase of launching accurate support bots. We'd love to hear what you think! https://ift.tt/v2FDetK June 13, 2024 at 11:50PM

Show HN: A keyboard-centric clipboard history app for macOS Hey HN, As a Software Engineer, I frequently copy and paste content. The fact that macOS clipboard buffer can keep only one item is very frustrating. It’s very annoying to copy → switch app → paste → switch app → copy → switch app → paste, and so on. Losing items I copied hours ago and having to find and copy them again is a waste of time. I tried many third-party clipboard managers like Alfred, Raycast, Paste, Maccy, etc. While great, they didn't fully meet my needs. As a developer, my requirements are: 1. Keyboard-centric operation to avoid using the mouse. I don’t want to waste my time moving my hands from the keyboard. 2. Display many clipboard history items at once. I don’t like the idea with big tiles, so I can see only 5-7 history items on my 32” monitor. 3. Full content preview for each clipboard item. 4. Quick search functionality. So, I created ClipBook for my own use. After months of development, daily use, and positive feedback from my colleagues, I decided to share it publicly. It’s free. All data is securely stored on your computer. I’m planning to make it open source as well. If you try it out, please let me know if you found it useful, if you have anything you’d like me to add, or if you have any other feedback. Happy to answer any questions. Much appreciated. https://clipbook.app/ June 11, 2024 at 10:10PM

Show HN: Using the djb2 hash to map IP addresses to readable words for the lulz Hi HN, This is more or less a fun experiment that I thought was worth sharing. Using Daniel J. Bernstein's [1] djb2 hash that he made when he was only 20 years old in 1991, we map names to hashes and provide reverse mappings using an english word list from dwyl [2]. You can see it here: https://ift.tt/3YZrBV8 Hamon (ハモン not 刃文) is derived from HAsh MOdulo Name. I hope you like it [3]!

Show HN: I Build an AI-Powered API That Instantly Obtains Website Information I built SiteProfile(siteprofile.io) to simplify how we access detailed website information. The main feature of SiteProfile is that you can obtain all relevant website information with a single, simple API call. With one API call, you can immediately get the following information: 1.Real-time Webpage Screenshots Instantly capture real-time screenshots in both PC or Mobile views. 2. AI-Generated Content: Generate content based on user prompts and website data, e.g. Describe the core functions of this website. 3.Comprehensive Website Info: Social Media Links, Contact Info, Basic Details, and Assets, all in one place. With just this API, you can instantly create an ai directory or similar website. SiteProfile is currently in the testing phase. During this period, all subscriptions are discounted. There are still a few minor issues, and I’m working hard to fix them. If you try it out, please let me know if you found it useful, if you have anything you’d like me to add, or if you have any other feedback. And if you have any questions, I’d be happy to answer. Much appreciated. https://siteprofile.io/ June 10, 2024 at 06:47AM
Show HN: I built a site to track your buy it for life items Hey HN, I've been on a mission to buy higher quality, sustainable products, especially when replacing things I use frequently. To better understand the value of these items, I built a site to track how often I use them. Here is my list so far: https://ift.tt/c9ZlLEx Feel free to sign up and share the items that have served you well! https://ift.tt/tVkh7TC You can also generate a sharable link for X (Twitter), complete with an open-graph image of your stats. Example: https://ift.tt/TMrKGX5 If there's interest, I have plenty of ideas to improve the site. With enough data, I aim to create lists of the best BIFL (Buy It For Life) items in various categories. Check it out and let me know what you think! https://ift.tt/gE56873 June 9, 2024 at 04:52AM
Show HN: I wrote a partial re-implementation of DirectMusic DirectMusic[1] is a deprecated Windows API for playing dynamic music scores authored using DirectMusic Producer[2]. It was originally released as part of DirectX in 1999 and discontinued with the release in Windows Vista around 2009-ish. Due to my involvement with projects[3] re-implementing an old game engine for the early 2000's games Gothic and Gothic II[4], I came to notice that existing solutions[5] were incorrect and hard to use. Thus, I was tasked with writing a new, correct re-implementation of the API. Today, my re-implementation is able to (mostly) play back so-called style-based segments[6] and is fully tested against both the Gothic and Gothic II soundtracks. I am actively working on getting the Lego Island 2 soundtrack working as well. There are many features of DirectMusic which the library does not currently support, simply because I have not been able to find or test soundtracks using them, so if you want to contribute, I'd love to know about software shipping with DirectMusic soundtracks!

Show HN: I built job search platform for Architects Hi HN, I started my solopreneur journey this year and I’d like to share something I’ve been working on: ArchGee - a job search platform for architects, interior designers, urban planners, and other professionals in the architecture field. Coming from an IT background, I’ve seen plenty of job boards for IT roles. However, my architect friends often struggle to find job opportunities specific to their unique skills. Archgee is designed to fill this gap. It’s tailored exclusively for the architecture community, making it easier to find relevant opportunities. At first I am planning to integrate jobs from other search platforms (jobs that are relevant to architecture), then partnering with industry companies to ensure high-quality job posts and aim to create a supportive space for networking and growth. I’m here to seek your thoughts and feedback. Mirza June 9, 2024 at 12:40AM
Show HN: A Small BitNet GPT in MLX For those of us nerds who like to tinker with language models, I thought of sharing an example ipynb that shows how to build a small gpt (kudos to @karpathy for teaching us minGPT) where you replace the nn.Linear layer with a BitLinear layers as introduced in the paper on 1.58 bit LLMs https://ift.tt/uWw6c9t https://ift.tt/sXl8K6m June 9, 2024 at 01:38AM
Show HN: Scipress.io – a Markdown writing platform like Notion Medium MkDocs Scipress is a writing platform with VS code editor built into the browser. It lets you make beautiful blog posts and programming docs with Markdown. Scipress supports code blocks with syntax highlighting, Katex, Tailwind CSS, images & videos, admonitions, popovers, blur screens, private posts, and a bunch of other cool stuff. You can also monetize via paywalls, if you want. I started this project almost a year ago to the date. This is my first time posting about it on HN. And if you're curious, I have made $0 from this project (but not for lack of trying). https://ift.tt/3TbgDSO June 7, 2024 at 07:42PM
Show HN: I created this land use visualisation for the Netherlands Last weekend, I tried creating an original visualization of something on many minds in my home country the Netherlands: land use. Much of our discussion revolves around land use—housing crisis, sustainable farming, solar energy—it's all about the land. To illustrate this, I created a map where each hexagon represents 0.06% (26,647 hectares) of land in the Netherlands. The color indicates the type of land use. https://ift.tt/UTMGiCa June 6, 2024 at 10:32PM
Show HN: A website that tailors your resume for each job you apply for Hey HN, I'm excited to share a project I've been working on for the past few months. As someone who has spent countless hours tweaking my resume for different job applications, I wanted to find a way to make this process more efficient and effective. So, I built a website that tailors your resume for each job you apply for. You can check it out here: https://resume.ink Looking forward to your thoughts!

Show HN: I built a tool to A/B test promotions to maximize conversions Hey HN, I've just begun my solopreneur journey. I've been a "serial starter" - often starting projects and never seeing them through, and I have finally finished my first project! Maybe this sentiment resonants with some of you, let me know in the comments below I built this tool as a simple no-risk method for turning more visitors into customers by A/B testing your sale promotions and automatically displaying the promotion with the highest conversion rate. Did you know that increasing your conversion rate by just half a percent can have a dramatic impact on your sales without needing to increase your traffic? Consider the following example for a $20 product on your website: To earn $1M in sales with a 2.5% conversion rate you would need: 2M visitors. To earn $1M in sales with a 3.0% conversion rate you would need: 1.66M visitors. What do you think is an easier way to get to $1M in sales: Attracting ~ 400K new visitors? Or raising your conversion rate by 0.5%? I hope some of you find this product useful, I would love your feedback! - Xylo https://ift.tt/cSDj3Y5 June 6, 2024 at 12:15AM
Show HN: Auto-matching and optimized carpooling for groups How it works: - Organizer creates an event and shares the link to it - People sign up as riders or drivers - 48 hours prior to event, everyone gets a text message asking to confirm. - 24 hours prior to event, the optimized carpooling routes are created. Right now drivers are limited to a max route of 30 mins long, will be more flexible soon. Everyone is messaged their route details, related rider/driver details, and drivers get a google maps route link to navigate.

Show HN: Hexbase – Find colors based on perceived difference I created this tool to help choose and remix colors with precision. Input reference colors, adjust their weights, and get suggestions as similar or different as you need. Differences are calculated using the CIE ΔE* metric. One use case could be finding a primary brand color aligned with your brand values but distinct from competitors. Thanks for taking a look! I hope it sparks some ideas. It’d be great to hear thoughts & feedback. https://ift.tt/eVciuGC June 3, 2024 at 09:04PM

Show HN: Generate PCB Footprints from text using AI Hi HN! This is a little project to generate PCB footprints from text descriptions. It works by teaching an LLM a compressed DSL representation for footprints. I think this is generally a good technique if you're trying to get LLMs to work on spatial problems. Right now I'm focused on reproducing footprint shapes, but after that I'll benchmark the correctness of the footprints using % overlap on known package descriptions, as well as a kicad_mod export I built this because I realized I needed to use AI to help tscircuit catch up to the decades of electronic design tool progress that I'm not able to utilize (as an MIT-licensed, Typescript project) Source code here: https://ift.tt/5TrRnu1 Feedback/critical opinions appreciated! https://ift.tt/2gQRxPT June 2, 2024 at 12:50AM
Show HN: Chess Twist I continue my experiment of transposing classic games onto an irregular grid. I've previously released variants of minesweeper and checkers. And now I'd like to share my variant of Chess. Chess can be a pretty punishing game, but I thought this was nevertheless a way to make it even more challenging by making it trickier to anticipate your opponent, even though both players still have the same information. From the playtests I've done, that challenge is pretty compelling. It also seems to be more fun at 2 people, where both players keep surprising one another. https://ift.tt/fs4jBNC June 1, 2024 at 02:11AM
Show HN: Every mountain, building and tree shadow mapped for any date and time I've been working on this project for about 4 years. It began as terrain only because world wide elevation data was publicly available. I then added buildings from OpenStreetMap (crowd sourced) and more recently from Overture Maps data. Some computer vision/machine learning advancements [1] in the past few years have made it possible to estimate tree canopy heights using satellite imagery alone making it possible to finally add trees to the map. The data isn't perfect, but it's within +/- 3 meters of so. Good enough to give a general idea for any location on Earth. Happy to answer any questions.
