Show HN: The cosine distance between Shawn and Sean Hi everyone. I had an interesting interaction with someone named Shawn (or was it Sean?) and it led to a blog post on embeddings, one of the foundational concepts for AI/ML. The post explores embeddings and cosine distance functions with some fun interactive animations. And, all the AI runs inside your browser, even on mobile! Additionally, this uses my Svekyll blogging tool ( https://svekyll.com ) which is like the Jekyll blogging tool but adds the power of Svelte. Svelte/Svekyll makes building these kind of interactive blogs much simpler. And, all these posts have a download button at the bottom which allows you to download the entire post as a svekyll blog. You can just "npm i && npm run build" to build it yourself, learn about the code used to generate the post, and tweak to your hearts content if you want to repurpose the blog contents. Would love to hear comments or suggestions. Thanks to my real friends Shawn

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.

One feature people like to use is “alerts” at certain price points. We have now extended this with LLM filters on the whole news feed so that you can create (near) real-time webhooks on arbitrary events like: - Notify me when Nvidia is worth 10 trillion - Notify me about AI breakthroughs - Notify me when Intel is the market leader again - Notify me about successful Starship launches - Notify me when a war breaks out - Notify me about bankrupt unicorn startups - Notify me about significant economic events The feature is still very early.

Show HN: A New Kind of Chat Room I’ve developed an application that reimagines chat rooms by integrating them with a world map. Each user can claim a rectangular piece of land on the map, referred to as a "banner." Users within close proximity are grouped into a chat room by the app. The banner’s size can expand or shrink based on the density of users in the area and the number of coins in the user’s account. Key Features: Real-World Interaction Model: Users are pseudo-anonymous, akin to real-world interactions. Coin balance determines user size and visibility ("stature"), while endorsements and other activities form a unique endorsement chart, serving as a digital representation. This allows for interaction without revealing one’s entire social or professional network. Community Clusters: Users can form open communities based on real-world locations. New users can discover and join these clusters via heatmaps, without needing specific URLs or hashtags. Initial Coin

Show HN: Get paid to do your own ML research I'm launching an experimental research grant that I call Cat's grant (I'll find a better name later). tldr: - you get paid to do your own research and report to me - you keep IP/ownership rights - 10 months duration - choose a grant size of $10k, $50k or $100k total (paid in monthly chunks) - Apply by sending an email to not_a_cat@fastmail.com How it works: You specify the grant size when applying: 10k, 50k and 100k. This total amount will be distributed over a period of 10 months. I will review each application within 1 week. The deadline to apply is June 9. The start date is flexible and can be the start of June, July, August or September. The total budget I will allocate to this is around 100-200k I haven't yet made a proper contract reviewed by lawyers.

Show HN: Blue Noise – Interactive Explanation of Void and Cluster Algorithm After reading about the generation of blue noise here on HN a few times my goal was to implement my own variant of the the Cluster and Void algorithm in the most straight-foward way possible, while also visualizing each step. (JavaScript is required in order to step through the algorithm) Most other Blue Noise generator implementations are optimized for speed. Many explanations of the Cluster and Void algorithm I found online were overly complicated or focusing on details that do no help the initial understanding. My implementation is optimized for readability and understanding. I find it very inspiring see an algorithm broken down to its most essential steps. For one in order to better understand the algorithm itself but also for transfering its key concepts to other tasks, for example when designing my own algorithms. Eg in my rather high level python/numpy implementation one can easily understand that the tw

Show HN: Meal planning – without the mental load TLDR; I applied the concept of "don't make me think" to the task of selecting meals, and assembling the shopping list for your grocery run. The basic idea for what I wanted is very simple: Rather than making a shopping list, I wanted to create a re-usable 'meal', with a list of ingredients I'd need to add to my shopping list to make that meal. Then, after selecting meals for the week I'd have a quick 'check' step, where I'm prompted to check the cupboard for each ingredient, before it's added to the shopping list (ie: I'll need ground beef to make tacos, but I already HAVE ground beef in the freezer). I originally built this out just for myself, but the result has been such a helpful and stress-free experience that I thought others might appreciate it as well. I think this tool could be well-suited for younger folks that are new to the labour of meal-planning. College students, newlyweds,

Show HN: I generated API documentation for all Java packages Hi HN! I'm excited to share a project I've been working on for the past year: Docland. It is an API documentation browser that generates documentation on demand (through compilation, not LLMs) for Java packages. Instead of relying on Javadoc, the built-in doc generator, I created the engine from scratch to give the documentations a modern look, build fast search indexes, and enable link resolution to other packages. I built Docland because I constantly found it frustrating to locate and view API definitions when programming. You'd have to Google the function/class name, skip all the SEO articles, find the page you want, yet the documentation might be poorly formatted or does not support searching. So I thought it would be really cool to create a documentation site dedicated for programming languages and libraries, so that you can find the docs all in one place with a uniform look. Docland currently only supports J

Show HN: LogsQL – opinionated query language for logs I don't like the existing query languages for Elasticsearch and Grafana Loki, because they are too awkward to use for typical logs' investigation cases. So I designed new query language - LogsQL - and wrote reference implementation for it as a part of VictoriaLogs - an open source database for logs. LogsQL is based on the following principles: - Simplicity. It is easy to write typical queries over logs in it. For example, a single word `error` is a valid LogsQL query, which returns all the logs with the `error` word. Another example is `_time:5m error`, which returns all the logs with the 'error' word over the last 5 minutes. - Composable building blocks similar to Unix pipes, which allow powerful filtering, transforming and calculating stats over the selected logs. For example, `_time:5m error | stats count() as rows` returns the number of logs with the `error` word over the last 5 minutes. - Readability. Typical Lo

Show HN: Spot – Simple, cross-platform, reactive desktop GUI toolkit for Go Hi HN, I’m excited to share Spot, a simple, cross-platform, React-like GUI library for Go. It is just a few days old and has lots of missing features but I'm happy with the results so far, and looking for some design feedback. Spot is designed to be easy to use and provide a consistent API across different platforms (mainly Mac & Linux). It’s inspired by React, but written in Go, aiming to combine the best of both worlds: the easy tooling & performance of Go with a modern, reactive approach to UI development. Key features: - Cross-platform: Leveraging FLTK[1] & Cocoa[2], Spot works on Mac, Linux, and the BSDs with plans for native Windows support in the future. - Reactive UI: Adopts a React-like model for building UIs, making it intuitive for those familiar with reactive frameworks. - Traditional, native widget set: Utilizes native widgets where available to provide a more traditional look and f

It is also surprisingly reliable, only sometimes mistaking a "oh" for a "zero" in a long string of numbers. I neither know when this was introduced nor who added this feature, but from the bottom of my heart: thank you, thank you, thank you, you have made my daily life a lot easier. I also haven't really explored the limits of the feature and under what conditions it starts failing, but: in my daily workflow so far, it's worked every time. This type of small improvements that remove a ton of daily friction are a blessing. Small thing, but I just thought I'd share this with HN in case it benefits others. May 24, 2024 at 10:52PM

Show HN: Excel to Python Compiler We (me and @aarondia) built a tool to help you turn psuedo-software Excel files into real-software Python. Ideally, Pyoneer helps you automate your manual Excel processes. You can try it today here: https://pyoneer.ai . How it works: 1. You upload an Excel file 2. We statically parse the Excel file and build a dependency graph of all the cells, tables, formulas, and pivots. 3. We do a graph traversal, and translate nodes as we hit them. We use OpenAI APIs to translate formulas. There’s a bunch of extra work here — because even with the best prompt engineering a fella like me can do, OpenAI sucks at translating formulas (primarily because it doesn’t know what datatypes its dealing with). We augment this translation with a mapping from ranges to variable names and types, which in our experience can improve the percentage of correctly translatable formulas by about 5x. 4. We generate test cases for our translations as well, to make sure the Python process

Show HN: We open sourced our entire text-to-SQL product Long story short: We (Dataherald) just open-sourced our entire codebase, including the core engine, the clients that interact with it and the backend application layer for authentication and RBAC. You can now use the full solution to build text-to-SQL into your product. The Problem: modern LLMs write syntactically correct SQL, but they struggle with real-world relational data. This is because real world data and schema is messy, natural language can often be ambiguous and LLMs are not trained on your specific dataset. Solution: The core NL-to-SQL engine in Dataherald is an LLM based agent which uses Chain of Thought (CoT) reasoning and a number of different tools to generate high accuracy SQL from a given user prompt. The engine achieves this by: - Collecting context at configuration from the database and sources such as data dictionaries and unstructured documents which are stored in a data store or a vector DB and injected if re

Show HN: Porter Cloud – PaaS with an eject button Hi HN! Porter Cloud ( https://ift.tt/9GMmbVZ ) is a Platform as a Service (PaaS) like Heroku, but we make it easy for you to migrate to AWS, Azure, or GCP when you're ready. Like Heroku, Porter takes care of a lot of generic DevOps work for you (like setting up CI/CD, containerizing your applications, autoscaling, SSL certificates, setting up a reverse proxy) and lets you deploy your apps with a few clicks — saving you a lot of time while developing. However, as you probably know, there’s a downside: platforms like this become constraining if and when your app takes off and you need to scale. The time you saved while developing can get pretty expensive once you’re paying for a lot of users — and the platforms tend to try to keep you locked in! Our idea is to give you the best of both worlds: use Porter Cloud for as long as it saves you time and development cost, but at any time you can press the “eject button” to migrate your app to

Show HN: SQLFrame – I ran PySpark without Spark on a SQL database Recently I open-sourced SQLFrame, a DataFrame library that implements the PySpark DataFrame API but removes Spark as a dependency. It does this by generating the corresponding SQL for the DataFrame operations using SQLGlot. Since the output is SQL this also means that the PySpark DataFrame API can now be used directly against other databases without the Spark middleman. I built this because of two common problems I have faced in my career: 1. I prefer to write complex pipelines in PySpark but they can be hard to read for SQL-proficient co-workers. Therefore I find myself in a tradeoff between maintainability and accessibility. 2. I really enjoy using the PySpark DataFrame API but not every project requires Spark and therefore I'm not able to use the DataFrame library I am most proficient in. The library currently focuses on transformation pipelines (reading from and writing to tables) and data analysis as key use cas

Then someone told me "give people what they want" and it seams people just look for transcriptions and to repurpose it. So I ditched the screen vision analytics part for now and focused on just the spoken text. Not sure if this was the right decision and if I now removed the main sauce from it. We will see. The pro

I currently do not have a job so I have treated this as my full-time job. 3.0 is not yet ready for release, but I wanted to show you some of the cool things I've done with it (see video in link or check out my youtube page for past progress updates https://www.youtube.com/@capsizegames4331 ). AI Runner is a privacy-forward, multi-modal offline AI application built with Pyside6, huggingface libraries, llamaindex and open source models. It allows for real-time text to speech conversations with chatbot agents that you can fully customize. The bots have personalities and "moods". The moods shift with the conversation. I am using custom agents and my own system for selecting actions which is very fast. The application also allows you to generate images using Stable Diffusion and controlnet

Paying Our “Fare” Share: Fare Compliance and Enforcement on Muni By Melissa Culross Tapping a Clipper card is one of the many ways to pay to ride Muni. Maybe this has happened to you: You board Muni and tap your Clipper card or pay your cash fare, but lots of other people get on without doing the same. We understand how frustrating it is to see people appear to cheat the system and ride for free. However, most people who don’t tap the Clipper card reader or pay at the fare box aren’t doing anything wrong.  At the same time, fare evasion has increased over the last few years. We take this issue seriously and are doing something about it.  We plan to hire more fare inspectors once our upcoming budget goes into effect.  Looks can be deceiving when it comes to paying fares  There are many ways to pay Muni fares, including with cash, Clipper and the Muni Mobile app. Discount fares and passes are available for certain riders.   Some passengers are allowed to ride Muni for free.

Show HN: I built an AI agent that upgrades NPM packages Hi HN, I built a tool [1] that resolves breaking changes when you upgrade npm packages. I know keeping my dependencies updated is good hygiene but I really have no motivations to do them. The time to fix breaking changes then validate them makes the ROI lopsided. Automating these helps me reduce the barrier to a good habit. It works on typescript and tsx projects. BYOK (bring your own GPT-4 key) for the codegen. MIT license. How does it work? - Bumps the package version, builds your project, and then runs tsc over your project to understand what breaks - Uses ts-morph [2] to create an AST of your code to understand the relationships between code blocks - Uses the AST to get type definitions for external methods to understand how to use the new package - Creates a DAG to execute coding tasks in the correct order to handle propagating changes [3] Try it out and would love to hear your feedback!

Show HN: Loglayer: A fluid logging interface for JavaScript loggers This has been in use on our production systems for around two years now at Switchboard ( https://switchboard.app ). The problem we had was that we were using two different logging libs for our frontend and backend at the time (specifically roarr, and bunyan), and the API for the logging libs were not compatible with each other. Loglayer was designed to wrap around popular JS logging libraries where you can swap out any underlying library without re-writing your log entries to adapt to the new library. One common example is using plain "console" as a starting integration, but later swapping to a logging library like Winston once you've nailed down which JS logging lib fits your use-case. You can also swap to another from there (which we have done from bunyan to pino on our backend) if you need to later on. It also provides a fluid API that standardizes how one should feed error, set context, and metadata.

Show HN: Ellipsis – Automated PR reviews and bug fixes Hi HN, hunterbrooks and nbrad here from Ellipsis ( https://ift.tt/UfIpcbQ ). Ellipsis automatically reviews your PRs when opened and on each new commit. If you tag @ellipsis-dev in a comment, it can make changes to the PR (via direct commit or side PR) and answer questions, just like a human. Demo video: https://www.youtube.com/watch?v=X61NGZpaNQA So far, we have dozens of open source projects and companies using Ellipsis. We seem to have landed in a kind of sweet spot where there’s a good match between the current capabilities of AI tools and the actual needs of software engineers - this doesn’t replace human review, but it saves you time by catching/fixing lots of small silly stuff. Here’s an example in the wild: https://ift.tt/9Rl31zM . Ellipsis (1) adds a PR summary; (2) finds a bug and adds a review comment; (3) after a (human) user comments, generates a side PR with the fix; and (4) after a (human) user merges the side PR and

Show HN: I built a non-linear UI for ChatGPT Hi HN, I built this out of frustration of the evergrowing list of AI models and features to try and to fit my workflow. The visual approach clicks for me so i went with it, it provides more freedom and control of the outcome, because predictable results and increased productivity is what I’m after when using conversational AI. The app is packed with features, my most used are prompt library, voice input and text search, narration is useful too. The app is local-first and works right in the browser, no sign up needed and it's absolutely free to try. BYOAK – bring your own API Keys. Let me know what you think, any feedback is appreciated! https://ift.tt/Rjrq6pW May 8, 2024 at 11:41PM

Show HN: I made DevOps as productized service I'm normal contractor programmer, for the past few years doing mainly DevOps on AWS. I noticed lot of smaller companies don't have enough work for full-time devops person nor they have cloud/aws knowledge on the team. Lot of them has similar needs. So my thinking is I can help them for flat montly fee to do all the infrastructure on AWS for them.

Show HN: I made a calculator builder to increase engagement and conversions Hi HN, I am a solopreneur in the evenings and a software engineer during the day. In the past, I have created lots of calculators for my web projects and freelancing friends. These were pretty basic, but users always welcomed them. I also used currently available builders, but the problem was that they were either slow, broke on mobile devices, had nonsense page view limits, or were expensive. Some even ticked all those boxes. So I have decided to create my own, with a simple interface, and called it Creative Widgets (if it ever takes off, I plan to add more exciting stuff like charts, etc, hence why generic “Widgets”). At this point, I am after feedback. I found myself running in a circle, building features because I think they're great to have, but I would much rather have features that are wanted by users. So, if your project/web benefits from the custom calculator, you can check it out. Thanks everyone.

Show HN: Skyrim – Open-source Large Weather Model (LWM) Zoo Hi HN, I'm Efe from Secondlaw AI. We are building physics-informed large AI models. Currently, we are focusing on weather modelling. To benchmark SOTA, we had to build a forecasting infra for all available large weather models and we could not find a solid tooling to do so, so we built Skyrim. Within <5 mins and <5 LOC you can run forecasts on par with global weather models that are run on 100K+ CPU HPCs! We are implementing more models & fine-tuning capabilities. Let us know if anything more we can add, also happy to answer any questions! https://github.com/secondlaw-ai/skyrim May 7, 2024 at 11:03PM

Show HN: Voltage Park – H100 GPU Orderbook Hi HN - Voltage Park is a GPU cloud powered by Nvidia H100s. We own and manage the infrastructure and currently have over 7,000 H100s live. We will be launching an additional 17,000 H100s in the next 2 months. Today, we are launching our H100 Auction Platform with 1,000+ GPUs live. This platform gives users on-demand access to compute for AI training, fine-tuning, and inference. We are growing the platform to over 5,000 H100s in the next month. We created the Auction Platform to make the process of procuring GPUs more transparent and simple. It allows you to see the supply and price of GPUs in real-time. Place an order for the number of GPUs you need and get near-instant access to the compute. We have been running this on-demand auction platform for the past 2 months in Beta. Early customers include Luma AI, 273 Ventures and Mirelo.ai. One great customer comment so far: “I love using Voltage Park auction. It's so empowering to know we can

Show HN: Rispose.com – A free tool to embed OpenAI Assistants on any website Hey, OpenAI recently released "assistants" - These have RAG built into the API, which means that you can provide up to 10.000 files to the assistant without the overhead of dealing with vector databases, splitting files into chunks and more. They work surprisingly well, so I've built a free simple tool to embed them on websites. It has no dependencies and simply uses fetch to communicate to my backend which proxies openai. In the future I plan to add more widget embedding options (currently only chat is available). Let me know if you have any specific questions about either the tool or openai assistants in general. https://rispose.com May 3, 2024 at 08:08PM

Show HN: A URL shortener that lets you change the destination source @deveshb15 and I built a URL shortener because the existing ones don't let you change the destination source once you create it. The main benefit is really just the fact that once you claim a link, you don't need to claim another and you can change the destination that link leads to as many times as you want - we need this a lot and don't want to pay a monthly fee for this. We used nextjs for frontend and backend, firebase for authentication and database, and used middleware in nextjs to the redirect url to desired location. Give it a go and let me know if you have any feedback. Thank you https://www.linklee.xyz/ May 6, 2024 at 11:19PM

Show HN: Touvlo – Technical Interviewing for Hardware Engineers (By Humans) Hi HN! Touvlo is a platform where you can delegate your technical interviewing for hardware engineers to us, so that you can focus on building your product instead. Our interviews test real-world engineering skills, largely via a collaborative CAD session through our in-browser platform. You can think of it as a pair-coding session between the interviewer and the interviewee, but for hardware. Interviews are conducted by real hardware engineers with industry experience (currently my co-founder, Danae). After each interview, you get a detailed score card, as well as full, timestamped recording of the interview. There's no pricing page yet, but we charge 220$ per interview, with discounts for monthly packages for 10 interviews or more. If you're a hardware/robotics startup, give us a try: we can help you hire better and save you time. Drop us an email (founders@touvlo.co), or sign up for a demo interview

Show HN: An AI model that busts AI faces Hey HN, I'm an AI enthusiast and I am launching apps that use ML to solve problems that we all have. I realized that there are a lot of deepfake faces on youtube and social media, so I thought it would be useful (and fun!) to have a tool that can bust those AI faces. So I built DeeFace for 2 reasons: 1. Check if the face you're looking at is real or not 2. For fun! It's something that I from half a year ago would look at and aspire to build someday. I think it's soemthing anyone who's just starting out with ML would appreciate. I hope this tool is fun for you to use as it was for me to build. Would love to hear your feedback on this.

SFMTA Board Approves FY 2025 and FY 2026 Budget By Andrea Buffa With our new budget, people can still get where they need to go on more than 70 Muni routes.  On Tuesday, April 16, the SFMTA Board of Directors unanimously approved the agency’s FY 2025 and FY 2026 SFMTA operating and capital budgets. The consolidated budget has just been sent to the Mayor’s Office for review. Next, it will head to the Board of Supervisors for final review.  With this budget, we can continue to provide:    Transit service on 72 Muni routes   Improvement projects that help make Muni safer, cleaner, faster and more reliable   Paratransit service for half a million seniors and people with disabilities every year  Street safety programs and projects like new street designs that make our roads safer for everyone  We’ll share how we got to this stage, and the importance of your feedback. We’ll also cover some of the key features of our budget and what you can expect next in the proc

Show HN: Hacker Search – A semantic search engine for Hacker News Hi HN! I'm Jonathan and I built Hacker Search ( https://ift.tt/4y5cfEh ), a semantic search engine for Hacker News. Type a keyword or a description of what you're interested in, and you'll get top links from HN surfaced to you along with brief summaries. Unlike HN's otherwise very valuable search feature, Hacker Search doesn't require you to get your keywords exactly right. That's achieved by leveraging OpenAI's latest embedding models alongside more traditional indexes extracted from the scraped and cleaned up contents of the links. I think there are many more interesting things one could build atop the HN dataset in the age of LLMs (e.g. more explicitly searching for technical opinions, recommending stories to you based on your interests, and making the core search feature more useful). If any of those sound interesting to you, head over to https://ift.tt/ElbIWcr to get notified when I launc

Show HN: SpRAG – Open-source RAG implementation for challenging real-world tasks Hey HN, I’m Zach from Superpowered AI (YC S22). We’ve been working in the RAG space for a little over a year now, and we’ve recently decided to open-source all of our core retrieval tech. spRAG is a retrieval system that’s designed to handle complex real-world queries over dense text, like legal documents and financial reports. As far as we know, it produces the most accurate and reliable results of any RAG system for these kinds of tasks. For example, on FinanceBench, which is an especially challenging open-book financial question answering benchmark, spRAG gets 83% of questions correct, compared to 19% for the vanilla RAG baseline (which uses Chroma + OpenAI Ada embeddings + LangChain). You can find more info about how it works and how to use it in the project’s README. We’re also very open to contributions.

Show HN: I made a site for sharing 'work in progress' updates I've always been fascinated by seeing other people work. Not just their end result, but the process that got them there. Over the years builders have become more willing to share their process. But those updates were scattered throughout the web on different blogs and social media accounts. So I made a social network, very similar to Twitter, focused solely on answering the question "What are you working on right now?" Throughout the day people share small updates of what they have completed. I find it both interesting and motivating to see people make progress on their projects. It's mostly bootstrapped startups, but there are also some authors writing books and people working on various hobby projects. https://wip.co It's invite-only at the moment to protect the community from an influx of new users (sorry!), but curious to get HN's view on this and whether they'd consider joining such
