Show HN: The cosine distance between Shawn and Sean https://ift.tt/9w4vrpc

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 and Sean for providing feedback. Shawn provided a discount code for the AI.engineering summit coming up (but to be very clear this is not a paid post in any way, it truly arose from a missed email connection that spawned me to think about embeddings). Hope you enjoy it. https://ift.tt/eg6Z3Y0 June 1, 2024 at 12:49AM

Show HN: Every mountain, building and tree shadow mapped for any date and time https://ift.tt/Frpyvn2

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.

Show HN: Webhooks for Any Event Hi, co-founder of markets.sh here. We are doing a lot of news processing and analysis around stocks and companies. 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. If you write that you’re from Hacker News in the support chat, I’ll give personal support. Would greatly appreciate all feedback https://ift.tt/oiHBxt6 May 30, 2024 at 10:10PM

Show HN: A New Kind of Chat Room https://ift.tt/nwXiPZY

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 Coins: New users start with 1000 coins. These coins can be used to endorse other users' content, earning stakes in the endorsed banner. When others endorse that banner, the original endorser gains more coins. This endorsement economy is experimental, and could eventually involve crypto tokens. Useful Points: Banner Interactions: Clicking on a banner opens it fully. A button with a chart icon on the top right flips the banner to display the activity chart. Compatibility: The application currently works best on Google Chrome. Heatmap View: Zooming out on the map reveals a heatmap of banners. Side Panel Tabs: First Tab: Displays a feed of content from the visible map area. Second Tab: Contains the cluster chat. Current User Base: At the moment, only my friends and family are using the application, so banners are predominantly found in the Chicago area. For more details, refer to the white paper provided. I’m excited to share this application and look forward to your feedback! https://beescribe.com/ May 28, 2024 at 11:07AM

Show HN: Get paid to do your own ML research https://ift.tt/w8XI3KE

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. If interest is strong enough, I will do it and try hard to keep the spirit of what is said here. The contract will be under Swiss law. Rationale: I get to meet cool people, promote and follow cool research. You get to do the research you want with little red tape (I'll be the sole decision maker for applications. Paperwork will be done with the help of other people). Application process: You choose the grant size you apply for. You can apply to multiple ones at the same time. Then, you may be accepted for one grant option or rejected for all. The process has 3 stages: - Email application - First screening call - Second call with more in-depth questions If you complete the 3 steps, you are accepted in the grant program. Reporting requirements: You are expected to produce the following: - A weekly email report that can be as short as a single sentence (meant as a pulse that you are still here) - A monthly research update that has to be public, in the format you want (github file, blog post…) - Do a monthly call with me, discussing the monthly research update Payment schedule: One payment of 10% of the total amount will be made at the end of each month while the grant is active. The grant may be canceled if the reporting and effort is insufficient. The bar for this will be reasonably low. Effort and time spent will be considered good enough for keeping the Grant active. Research directions: You are free to decide what topic to research. Reading and studying during the research is considered normal. I will try to be helpful and suggest research directions and ideas. I will only consider applications in the domains of Machine Learning, Deep Learning and AI broadly speaking. With a preference for topics related to the following: - LLMs and Transformer architectures - Mechanistic interpretability - World models - Self play / synthetic data - Probabilistic programming Copyright and IP rights: The research remains your intellectual property. You can use it and commercialise it as if you produced it independently of the grant. Time commitment: You are expected to spend at least 50% of your working time on research related to the grant. You may have other commitments at the same time, as long as you can free up enough time. Selection criteria: - How excited I am about the research you want to do - Whether I believe you can make good progress on it - Intrinsic motivation and strong determination How to apply: Send an email to not_a_cat at fastmail com with the following: - Subject: "Application for Cat's Grant [10k, 50k, 100k]". Only keep the grant size(s) that you actually apply for, eg [50k] or [10k, 50k]. - Info about yourself, please include links to github/linkedin and/or resume - Recent projects/research you've done if any - Outline of the research you want to do as part of the grant. It's ok if you only have a vague idea, but better if you have something specific. It can be new or existing research. - Anything else you think is relevant. Evidence of strong capability is a plus, even if unrelated to ML research. Happy to answer questions or comments. May 27, 2024 at 09:54PM

Show HN: Blue Noise – Interactive Explanation of Void and Cluster Algorithm https://ift.tt/rgHK7ck

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 two phases of the algorithm (phase 2 and phase 3) have no data dependency between each other and can therefor be parallelized. Additionally the numpy implementation demonstrates how the application of high level concepts like rank-polymorphism and convolution allow to express a sophisticated algorithm in only a few lines of code. Hope you like it. https://ift.tt/SbNyH2J May 28, 2024 at 05:07AM

Show HN: Meal planning – without the mental load https://ift.tt/N1UGeQy

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, and families with young children. You can try it out without needing to register or provide any personal information, and I'd love your feedback! https://supperstock.ca/ May 28, 2024 at 02:04AM

Show HN: I generated API documentation for all Java packages https://ift.tt/6H7BEUF

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 Java, but more programming languages can be supported thanks to its modular architecture. Please try it out and let me know what you think! Also, the process of building Docland was extremely fun and challenging. I'm happy to share about that too. Thank you! Martin https://docland.io May 26, 2024 at 07:35PM

Show HN: LogsQL – opinionated query language for logs https://ift.tt/p1BtFLY

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 LogsQL queries must be easy to read and understand even for persons unfamiliar with it. Take a look at LogsQL docs [1] and try using VictoriaLogs [2] in production. If you like Unix way and KISS design principle, then you'll enjoy LogsQL :) [1] https://ift.tt/rZgqfbQ [2] https://ift.tt/hDk9sPN https://ift.tt/rZgqfbQ May 23, 2024 at 08:28AM

Show HN: Spot – Simple, cross-platform, reactive desktop GUI toolkit for Go https://ift.tt/DgJ19Hc

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 feel. Why I built it: I was searching for a cross-platform GUI toolkit for Go that had a more traditional appearance, and none of the existing options quite met my needs. I then started playing with Gocoa and go-fltk and suddenly I worked on an experiment to see how challenging it would be to build something like React in Go, and it kinda evolved into Spot. ¯\_(ツ)_/¯ In 2024, is there a still place for classic desktop GUIs—even with a modern spin? I’d love to hear your thoughts, feedback, and any suggestions for improvement. Also, contributions are very welcome. Thank you for checking it out!

Show HN: You can now cut and paste from scanned documents in Firefox I just realized you can now open a PDF document in Firefox and select text directly from scanned images embedded in the document (so basically transparently reliable doing OCR). 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 https://ift.tt/dU0rPVl

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 matches your Excel process. 5. We give you back a Jupyter notebook that contains the code we generated. If there are pieces of the Excel we can’t translate successfully (complex formulas, or pivot tables currently), then we leave them as a TODO in the code. This makes it easy for you to hop in and continue finishing the script. Who is this for: Developers who know Python, primarily! Pyoneer might be useful if: 1. You’ve got an Excel file you’re looking to move to Python (usually for speed, size, or maintenance reasons). 2. There’s enough logic contained in the notebook that it’s going to be a hassle for you to just rewrite it from scratch. 3. Or you don’t know the logic that is in the Excel workbook well since you didn’t write it in the first place :) Post translation, even if Pyoneer doesn't nail it perfectly or translate all the formulas, you'll be able to pop into the notebook and continue cleaning up the TODOs / finish writing the formulas. What the Alpha launch supports: Launched early! Currently we’re focused on supporting: 1. Any number of sheets, with any reference structure between them. 2. Cells that translate as variables directly. We’ll translate the formulas to Python code that has the same result, or else we’ll generate a TODO letting you know we failed translating this cell. 3. Tables that translate as Pandas dataframes. We support at most one table per sheet, at the tables must be contigious. If the formulas in a column are consistent, then we will try and translate this as a single pandas statement. We do not support: pivot tables or complex formulas. When we fail to translate these, we generate TODO statements. We also don’t support graphs or macros - and you won’t see these reflected in the output at all currently. Why we built this: We did YCS20 and built an open source tool called Mito( https://trymito.io ). It’s been a good journey since then - we’ve scaled revenue and to over 2k Github stars ( https://ift.tt/d1CRbQW ). But fundamentally, Mito is a tool that’s useful for Excel users who wanted to start writing Python code more effectively. We wanted to take another stab at the Excel -> Python pain point that was more developer focused - that helped developers that have to translate Excel files into Python do this much more quickly. Hence, Pyoneer! I’ll be in the comments today if you’ve got feedback, criticism, questions, or comments. https://ift.tt/18KA49k May 24, 2024 at 12:40AM

Show HN: Porter Cloud – PaaS with an eject button https://ift.tt/8z96U1K

Show HN: Porter Cloud – PaaS with an eject button Hi HN! Porter Cloud ( https://ift.tt/pLUytBa ) 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 your own AWS, Azure, or GCP account as you please. We make it seamless to break out, so you’re no longer subject to the rigid constraints of a conventional PaaS. You can migrate in a few simple steps outlined here: https://ift.tt/iGPR6wo . A bit of background: we first launched on HN almost 3 years ago with our original product ( https://ift.tt/8mBf9ai , https://porter.run ), which deploys your applications to your own AWS, Azure, or GCP account with the simple experience of a PaaS. Since then, we’ve helped countless companies migrate from a PaaS to one of the big three cloud providers. Most of them had gotten started on a PaaS in the early days to optimize for speed and ease of use, but ultimately had to go through a painful migration to AWS, Azure, or GCP as they scaled and ran into various constraints on their original PaaS. Interestingly, we learned that many companies that start on a PaaS are fully aware that they’ll have to migrate to one of the big three public clouds [1] at some point. Yet they choose to deploy on a PaaS anyway because outgrowing a cloud platform is a “champagne problem” when you’re focused on getting something off the ground. This, however, becomes a very tangible problem when you need to migrate your entire production infrastructure while serving many users at scale. It’s a “nice problem to have”, until it isn’t. We’ve built Porter Cloud so that the next generation of startups can get off the ground as quickly as possible, with a peace of mind that you can effortlessly move to one of the tried and true hyperscalers when you are ready to scale. We are excited to see what people build on Porter Cloud. If you’ve ever dealt with a migration from a PaaS to one of the big three cloud providers, we’d also love to hear about your experience in the comments. Looking forward to feedback and discussion! [1] By “big three clouds” we mean the lower-level primitives of each cloud provider. We don’t mean their higher level offerings like AWS App Runner, Google Cloud Run, or Azure App Service, since those run into the same PaaS problems described above. May 23, 2024 at 11:47PM

We've successfully utilized it in genomics to associate billions of "k-mers" with taxonomic identifiers while maintaining an efficient memory footprint. But the data structure is also useful beyond computational biology, particularly where you have large unique key domains and constrained value ranges. Available under an Apache 2 license.

Show HN: SQLFrame – I ran PySpark without Spark on a SQL database https://ift.tt/yNjTSCb

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 cases. It does offer some ability to read from files directly but they must be small although this can be improved over time if there is demand for it. SQLFrame currently supports BigQuery, DuckDB, and Postgres with Clickhouse, Redshift, Snowflake, Spark, and Trino in development or planned. You can use the "Standalone" session to test running against any engine supported by SQLGlot but there could be issues with more advanced functions that will be resolved once officially supported by SQLFrame.

Show HN: I Built a Tool to Stop Cold Email Spam https://ift.tt/8J0CKdz

Show HN: I Built a Tool to Stop Cold Email Spam Hi HN! I'm Louw, founder of the enterprise insurtech scale-up Root[0]. Over the last 8 years, my inbox has been flooded with unsolicited emails, especially since early 2023. Recruitment services, outsourced software development agencies, and a crazy amount of lead generation services (thanks, Apollo!) drowned my inbox. To solve this, I created Unspam. Initially, it was a simple tool for myself and fellow founders to reduce noise. And it worked — about 10% of my emails were swiftly and accurately categorized as unsolicited messages. Given its success, I've decided to package and share Unspam with the broader community, evolving it into Unspam.io. How it works: 1. Hook up your Gmail 2. Unspam monitors received mail in the background 3. Unsolicited emails are labeled and archived Please try it out and let me know your feedback. What would you improve? https://unspam.io --- [0] https://ift.tt/8JWP3Mt [1] PS: I value privacy intensely. Unspam doesn’t record, store, or train on your emails. No need to. https://unspam.io May 19, 2024 at 02:00AM

Show HN: I got tired of losing great dev resources, so I'm making DevCheatSheets https://ift.tt/0XUudPo

Show HN: I got tired of losing great dev resources, so I'm making DevCheatSheets Over the years, I've found thousands of awesome blogs, StackOverflow answers, YouTube videos and, most recently, ChatGPT prompts that have helped me a ton in my software development work. The problem is, I lose them. I've talked to a ton of developers, and they all have various ways of partially solving this problem: - Notion documents with messy link dumps - 1,000,000 tabs open constantly - A bookmark folder that takes up half of your disk space DevCheatSheets is going to solve this by serving as a repository of useful developer resources that you can share with others. You will be able to create code snippets to remember for future projects, GPT prompts that gave you great output and more. You will also be able to discover new resources from other developers that are specific to your focus and chosen languages. DevCheatSheets is currently in development, but you can visit the site to sign up for a free newsletter to get updates on its development! https://ift.tt/A43Oxtk https://ift.tt/jJ0kfQv May 17, 2024 at 09:28PM

Show HN: Ask Hacker Search – Find out what HN thinks about any topic https://ift.tt/E5mQbuD

Show HN: Ask Hacker Search – Find out what HN thinks about any topic Hi HN! I'm Jonathan and I built Ask Hacker Search ( https://ift.tt/JpQR091 ), an LLM-powered version of Hacker News' Ask HN. Unlike Ask HN, Ask Hacker Search doesn't solicit new contributions from HN readers. Instead, it leverages Hacker News' historical data to answer questions, and offers LLM-generated summaries of those. I've used it for questions like "Should I use Drizzle or Prisma?" or "What is a good screen capture that allows easy zooming effects on Mac?". It is particularly useful when you're interested in understanding HN readers' sentiment about a topic, or when looking for expert insights on topics of interest to HN readers. I've been using it continually while building it, and have found it particularly useful to find software libraries recommended by HN or get quick vibe checks on hot topics. This builds on my release of Hacker Search two weeks ago ( https://ift.tt/C9wOxtS ), which offered a semantic search engine over top HN submissions. It's not just a small upgrade: covering comments was the #1 requested feature after that launch, so I rebuilt the near entirety of the product to support that. Please try it out and let me know what you think of it! I have to limit the number of LLM summaries each person can get for free, as this is entirely self-funded. If you hit the limit, you can subscribe for more summaries generated by a better model ($8/month), or bring your own compute by running inference on Ollama on your machine! https://ift.tt/JpQR091 May 17, 2024 at 12:11AM

Show HN: I'm 17 and wrote a guide on how to build your own programming language https://ift.tt/41lqFKy

Show HN: I'm 17 and wrote a guide on how to build your own programming language Hey! I’m JC. I’m 17 and part of Hack Club, a nonprofit where we help teenagers ship programming projects with their friends while growing technically. A while ago, I asked myself the question, “How exactly do programming languages work behind the scenes?” It seemed really daunting until I went to a half hour workshop at a high school hackathon about writing a tree-walk interpreter and realized that getting started was actually super fun. This guide is designed in the vein of that - to get people, especially teenagers, started on learning how to build a programming language in a literal weekend by actually shipping one. It’s a stepping stone for learning the big things - compilers, optimizations for performance, etc. It’s very inspired by Crafting Interpreters and why’s poignant guide, but meant to be approachable in a weekend. Some backstory on me: A year ago I finished high school early and joined Hack Club full-time to build projects like this. I’ve been programming since COVID, and learned how to code primarily by shipping things that seemed daunting to me and taking inspiration from people taking the time to break down various topics online. Give it a try and take it out for a spin! Constructive feedback is also really appreciated. It’s open source on GitHub at https://ift.tt/3hSmHtq https://ift.tt/90jhT5n May 16, 2024 at 09:34PM

Show HN: Julep: A platform to manage memories, knowledge and tools for LLM apps https://ift.tt/DOqG8QS

Show HN: Julep: A platform to manage memories, knowledge and tools for LLM apps Hi all! We've built our fair share of LLM apps, everything from Shopify agents to real-time clones of "Samantha" from "Her". We started facing a lot of annoyances & issues repetitively with building functional apps. So we sifted through 97K posts from the OpenAI Community to confirm and find people with similar problems (& we did). It turns out that there are a handful of low-level problems that everybody who is building an AI app that works well needs to solve: statefulness to manage conversations interaction interface between multiple agents and multiple users. robust document search dynamic tool calling from different apps swapping out different LLMs/models while preserving state, And that's exactly what we ended up making Julep to be. We built this as a prototype to solve our problems, and now we want to lower the barrier for someone to create functional and production-ready LLM apps. For more advanced stuff; We're also working on a task specification that defines a task execution framework for LLMs using a YAML format. It includes task triggers, available tools, debugging options, input and output schemas, and workflows. The main workflow is the entry point, with conditional transitions, error handling, and mapping operations for parallel processing. We want to make a Supabase-like backend for AI apps with a great DX. So if you're interested in this stuff or want a platform that you can make design decisions for, specifically for yourself, please submit PRs, become a maintainer, or join the Discord to check out cool examples we're building! https://ift.tt/4oMaPgU May 14, 2024 at 11:57PM

Show HN: I built a simple task capture inbox app I've always been frustrated with the complexity of todo mobile apps. I use Todoist and Notion to manage my work, for instance, but every time I'm out and about and think of a task I need to capture, the mobile apps feel too complex. Or I might think of a feature to add to a product, but don't want to deal with Linear's mobile web view. So, I built Defer: a simple iOS "capture" app that syncs to your menu bar on your Mac. No signup needed, it all "just works" with your Apple ID. Intentionally simple and lightweight. https://deferapp.com/ May 14, 2024 at 01:38AM

Show HN: I built a website to create images from LaTex https://ift.tt/8R04cbS

Show HN: I built a website to create images from LaTex Hey everyone, I was doing some tests with Gaussian Blur and the 2D Gaussian formula. While writing code for the formulas (I'm just trying to learn new things, that's all), I wanted to see LaTeX formulas in my IDE as images or in any convenient way. However, I couldn't find any proper method, such as writing LaTeX as a comment and seeing them as images, etc. So, I started to create my 2-step project: a LaTeX-to-image website & plugin for my IDE. I've completed the first step of this project. I've created a website called https://pictotex.com/ I didn't return to this project due to things happening in my life, but today I just checked my CloudFlare account to see what is going on and I was surprised because I'm receiving 50-60 unique visitors daily. This is very "unique" for me. I plan to add a few more features, like maybe creating a service to use "blang/latex" for better results. I hope this website helps you, even in a small way. I'd like to get your ideas & feedbacks. Behind the scene is very simple: NextJs, Supabase, Vercel https://pictotex.com May 11, 2024 at 07:52PM

Show HN: AI Runner – my personal opensource, local, multi-modal, AI assistant https://ift.tt/Q0lyxpk

Show HN: AI Runner – my personal opensource, local, multi-modal, AI assistant AI Runner is an application I have been working on for well over a year. I am the only developer on the project. 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 (previous versions allowed Kandinsky), LLM for chatbots and RAG retrieval using Mistral 7b and T5, multi-lingual text-to-speech using speech-t5, bark and espeak. The whole thing can run on a single 2080s video card, or you can split it between multiple GPUs by assigning models to available cards. For example, I have a 2080s which I use for Stable Diffusion, and a 3060 that I use for the other models. I've built in lots of features such as drawing tools, RAG for documents and websites, image generation with the LLM or custom prompts and more. I post about it often on my Twitter acount ( https://twitter.com/xw4ffl35x ). In addition to being a stand-alone application, the goal is to make it usable as an engine to power other applications. For example I plan to use it to power an RPG I am developing in Pygame. The application is pure python and can be compiled with pyinstaller using the installation scripts included in the main repo ( https://ift.tt/tIAark1 ). I am currently working on v3.0.0 which is under heavy development and is not stable. The last stable version came out over 8 months ago and was version 2.2 (you can find it tagged on github). This new version is a complete refactor and uses proper threading, has enhanced privacy and security features (the app is not able to access the internet and complete works around any security holes in the huggingface libraries by preventing them from accessing the internet or creating a .cache folder - there's more information about this in the README). --- I believe it is crucially important to have open source options when it comes to AI. I do not want to live in a world that is dominated by OpenAI. I want free, open source models and the ability to run them locally, offline for free.

Show HN: I built an AI agent that upgrades NPM packages https://ift.tt/ax2YZcO

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: Meemaw – Trustless and grandma-friendly wallet as a service https://ift.tt/6Sc42Z5

Show HN: Meemaw – Trustless and grandma-friendly wallet as a service Hey HN, Marceau here, founder of Meemaw. I was working on a different project (communities with better aligned incentives) for which I needed users to have access to a crypto wallet. I couldn't afford users to have to deal with private keys and what not, and I did not feel comfortable being locked to a non-transparent third-party provider for something as important. So I built an internal "wallet-as-a-service" around audited librairies. I dropped the original project since then and that service evolved into Meemaw. Many "web3 projects" would be better off without any web3 component. But if you do need your users to have a wallet, there are a few good reasons to use something like Meemaw: - great UX (no faffing around with private keys or seed phrases, easily customisable) - great DX (get up and running quickly, integrate with your existing system easily) - more secure (MPC, trustless) - low dependency risk (you've always got the option to self-host or export existing wallets) If you'd like a refresher on MPC wallets or Wallet-as-a-Service, I did my best to explain it without BS industry jargon: https://ift.tt/JtRdU0j If you have Docker and Node installed on your machine, you can have a full example running in less than 5 minutes: https://ift.tt/2anZMD8 You can already self-host Meemaw, and there will soon be cloud hosting as well, with the option to easily switch from one to the other at any time. The closed-source competitors are all (very) well-funded, but I think we can provide a better developer experience with higher security and reduced dependency risks. Right now, Meemaw is probably not ready for production, but we'll get there sooner rather than later. Your feedback would be greatly appreciated to continue moving in the right direction :) https://ift.tt/ZBFLCJT May 10, 2024 at 08:01PM

Show HN: Loglayer: A fluid logging interface for JavaScript loggers https://ift.tt/2QICT3n

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. This means regardless of the underlying logging library used, developers use the same API to write logs throughout. log .withMetadata({ some: 'data'}) .withError(new Error('test')) .info('my message') With this new 4.x release, I added a plugin system allowing you to manipulate data before it is shipped to the underlying JS logger). https://ift.tt/2nFgeYs May 10, 2024 at 01:45AM

Show HN: Ellipsis – Automated PR reviews and bug fixes Hi HN, hunterbrooks and nbrad here from Ellipsis ( https://ift.tt/D3XEM7b ). 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/VABGbEp . 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 adds another commit, re-reviews the PR and approves it Here’s another example: https://ift.tt/zmFs8Wf... , where Ellipsis adds several comments with inline suggestions that were directly merged by the developer. You can configure Ellipsis in natural language to enforce custom rules, style guides, or conventions. For example, here’s how the `jxnl/instructor` repo uses natural language rules to make sure that docs are kept in sync: https://ift.tt/2P7wrkM... , and here’s an example PR that Ellipsis came up with based on those rules: https://ift.tt/VN3BiFW . Don’t worry, your code is never stored or used to train models ( https://ift.tt/LomUCNV ). Installing into your repo takes 2 clicks at https://ift.tt/D3XEM7b . We’d really appreciate your feedback, thoughts, and ideas! https://ift.tt/AyaifpT May 9, 2024 at 11:14PM

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/tBfi41q May 8, 2024 at 11:41PM

Show HN: I made a calculator builder to increase engagement and conversions https://ift.tt/uUMfL16

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. Eugen https://ift.tt/sIAlfr5 May 8, 2024 at 03:54AM

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 spin up high-perf GPU nodes if we need them at affordable prices." -- Carl Johann SIMON (CEO, mirelo.ai) We will be hosting a Zoom on Thursday, May 9th at 12pm PT to go over the platform in more detail and answer any questions you may have. Please email ozan [at] voltagepark [dot] com if you would like to attend. We love the curiosity and spirit of the HN community, so please let us know what feedback you have. Our goal is to make machine learning accessible to all and this is just the start!

Show HN: Rispose.com – A free tool to embed OpenAI Assistants on any website https://ift.tt/UKROVZ2

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: SOTA Stream – daily research papers tailored to your interests There's too much noise when trying to keep up with AI research these days on Twitter. I wanted something that could help me stay off the site but still keep me up to speed on AI. I built a very simple prototype for a research paper digest that lets you specify your research interests and delivers a list of papers most relevant to you, daily. It's currently free as I'm funding the API costs myself. https://ift.tt/Iz6rEgx May 6, 2024 at 11:48PM

Show HN: An AI model that busts AI faces https://ift.tt/lZWA4as

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.

Show HN: Mininet-YAML – Create complex virtual networks through small YAML files Mininet-YAML is a powerful tool that simplifies the creation of virtual networks through YAML-configured topologies. By defining hosts, routers, and their interfaces in a YAML file, users can deploy complex network topologies directly on their machines within seconds. This tool integrates with Mininet and Open vSwitch to emulate network environments, allowing users to manage virtual nodes with the same granularity as physical hardware. Moreover, Mininet-YAML empowers users with advanced traffic engineering capabilities. They can effortlessly specify maximum transmission rates (goodput) between nodes, triggering automatic adjustments to network link capacities and routing table entries to achieve desired goodput levels. Leveraging a Mixed Integer Linear Programming (MILP) model solved by the CBC Solver, this tool ensures optimal network performance tailored to user specifications. https://ift.tt/mBDHkYq May 4, 2024 at 10:44PM

It's often a pain jumping between files, classes, functions, etc and copying/pasting everything, wrapping and annotating the blocks, and finally sending the prompt off for generation.

Show HN: SpRAG – Open-source RAG implementation for challenging real-world tasks https://ift.tt/zoqTw7i

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. We especially need contributions around integrations (i.e. adding support for more vector DBs, embedding models, etc.) and around evaluation. https://ift.tt/miwKVQT May 2, 2024 at 10:44PM

Show HN: I made a site for sharing 'work in progress' updates https://ift.tt/Sx3j8tP

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 a platform.

Show HN: Maps and Splats – Mashup of 3D tile maps with Gaussian Splats https://ift.tt/1SfDHZO

Show HN: Maps and Splats – Mashup of 3D tile maps with Gaussian Splats Hello HN! I’m excited to share this open-source community mashup showing the power and possibility of combining 3D Gaussian splat scans with traditional mesh-based 3D tiles maps in the browser. As you've probably seen on HN a bunch lately, Gaussian splats are a new method to allow custom 3D scans of scenes and objects [1] and Google Maps 3D Tiles API are the same 3D buildings and street views your familiar with in Google Earth or Google Maps, and recently they’ve been made available for inclusion in web apps. Combining splats + 3d map mixes highly detailed real-world custom micro-scans with the macro-level 3D imagery from satellite data. This is useful for civil engineering, transportation planning, real estate, construction, creative production, and so much more – we’re just scratching the surface.
