Show HN: Brisk a complete CI system is now Open Source Brisk is a complete CI system that runs your test suite in seconds. The main speedup over standard CI systems (think CircleCI or Github Actions) is that we maintain your test environments and don't rebuild them on each test run. This allows you to scale up your workers without just scaling up the build time on each test run. Brisk can be run from your local dev environment (the command line or VS Code) allowing your to access the speed of many servers from your local machine or it can be run as part of a traditional CI/CD pipeline (in Github actions etc). I've been working on Brisk for the last few years and I've decided to open source the project. You can now run your own super fast CI service on your own hardware or in your own cloud. https://ift.tt/QCwzkX9 https://ift.tt/I1X50Jn May 30, 2024 at 04:46AM

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 09:37AM
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 08:24PM
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/npoiUCS May 28, 2024 at 03:37AM
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 12:34AM
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 06:05PM

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: 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 relevant - Allowing users to upload sample NL <> SQL pairs (golden SQL) which can be used in few shot prompting or to fine-tune an NL-to-SQL LLM for that specific dataset - Executing the SQL against the DB to get a few sample rows and recover from errors - Using an evaluator to assign a confidence score to the generated SQL The repo includes four services https://ift.tt/6M8dCER : 1- Engine: The core service which includes the LLM agent, vector stores and DB connectors. 2- Admin Console: a NextJS front-end for configuring the engine and observability. 3- Enterprise Backend: Wraps the core engine, adding authentication, caching, and APIs for the frontend. 4- Slackbot: Integrate Dataherald directly into your Slack workflow for on-the-fly data exploration. Would love to hear from the community on building natural language interfaces to relational data. Anyone live in production without a human in the loop? Thoughts on how to improve performance without spending weeks on model training? https://ift.tt/erUiSsA May 23, 2024 at 09:20PM

Show HN: Neosync – Open-Source Data Anonymization for Postgres and MySQL Hey HN, we're Evis and Nick and we're excited to be launching Neosync ( https://ift.tt/HsQNw9h ). Neosync is an open source platform that helps developers anonymize production data, generate synthetic data and sync it across their environments for better testing, debugging and developer experience. Most developers and teams have some version of a database seed script that creates some mock data for their local and stage databases. The problem is that production data is messy and it’s very difficult to replicate that with mock data. This causes two big problems for developers. The first problem is that features seem to work locally/stage but have bugs and edge cases in production because the seed data you used to develop against was not representative of production data. The second problem we saw was that debugging production errors would take a long time and would often resurface. When we see a bug in production, the first thing we want to do is reproduce it locally, but if we can’t reproduce the state of the data locally, then we’re kind of flying blind. Working directly with production data would solve both of these problems but most teams can’t because of: (1) privacy/security issues and (2) scale. So we set out to solve these two problems with Neosync. We solve the privacy and security problem using anonymization and synthetic data. We have 40+ pre-built transformers (or you can write your own in code) that can anonymize PII or sensitive data so that it’s safe to use locally. Additionally, you can generate synthetic data from scratch that fits your existing schema across your database. The second problem is scale. Some production databases are too big to fit locally or just have more data than you need. Also, in some cases, you may want to debug a certain customer’s data and you only want their data. We solve this with subsetting. You can pass in a SQL query to filter your table(s) and Neosync will handle all of the heavy lifting including referential integrity. At the core of Neosync does three things: (1) It streams data from a source to one or multiple destination databases. We never store your sensitive data. (2) While that data is being streamed, we transform it. You define which schemas and tables you want to sync and at the column level, select a transformer that defines how you want to anonymize the data or generate synthetic data. (3) We subset your data based on your filters. We do all of this while handling referential integrity. Whether you have primary keys, foreign keys, unique constraints, circular dependencies (within a table and across tables), sequences and more, Neosync preserves those references. We also ship with APIs, a Terraform provider, a CLI and Github action that you can use to hydrate a CI database. Neosync is an open source project written in Go and Typescript and can be run on Docker Compose, Bare Metal, or Kubernetes via Helm. You can also use our hosted platform or managed platform that you can deploy in your VPC. We also have a hosted platform with a generous free tier - https://neosync.dev Here's a brief loom demo: https://ift.tt/qOxJTdQ?... We'd love any feedback you have! https://ift.tt/GQF6TrE May 22, 2024 at 11:23PM
Show HN: B-field, a novel probabilistic key-value data structure (`rust-bfield`) `rust-bfield` is a Rust implementation of our novel "B-field" data structure, which functions like a Bloom filter for key-value lookups instead of set membership queries. The B-field allows you to compactly store data using only a few bytes per key-value pair. 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. We hope it proves useful, and we're happy to answer any questions! https://ift.tt/Dbh1iCX May 22, 2024 at 11:23PM
Show HN: I made a Flutter app for loneliness. 14000 min of voice messages later: I hope you are doing better today than yesterday. (TLDR in the comments; or enjoy my story :) ) Why: About 11 months ago, I launched my app for the first time on Reddit's r/lonely because I had previously experienced loneliness myself during grad school. I wanted to reach out to people going through similar experiences by providing them with what would’ve helped me in the past. I felt this was an important mission for me and a much more rewarding one than my day job that I quit my job to work on the app full-time. It was necessary because I did not come from a programming background. I knew how to program in the sense of running scientific simulations on MATLAB, but creating the front-end and back-end for a consumer app was totally new to me, so I had to learn from scratch. I enjoyed everyday going to a cafe to learn from programming crash courses on YouTube, developing the app little by little, and eventually launching the app! The initial response was actually pretty great: 220 upvotes for the app launch post! How: I made the app to be based on voice, and nothing else: no profiles, no profile photos, and even no texts. The reason for that was I felt a lot of people felt lonely and had trouble finding meaningful online connections because of the modern communication medium which actually promotes superficial and viral contents over authentic and long-form contents. It is easy to see from examples: TikTok’s 30 second videos, Instagram’s eye-popping photos by beautiful people from the globe, and Twitter(X)’s 140-char spicy takes. Sure, these platforms offer us information about DIYs, trends, and news that can enrich our lives and entertain us, but they don’t by all means help us feel more connected to individuals. Even on Reddit, the contents tend to be more wholesome and there are hilarious comments that build on top of each other, but the actual sense of connection you feel with the users is tenuous. Focusing on voice worked! It was incredible listening to the heartfelt messages from strangers from all over the world who opened up about their loneliness and didn’t mind being vulnerable to other strangers. I have personally spoke with everyone that came by. The 14k minutes of voice messages do not include my own voice messages; they are all messages that people left for their own posts, to each other, or as replies to me. Highlights: There were some incredible moments, which would be too long to share in this post (leave a comment if you want to hear more!), but some of the highlights were (note: these are all from public conversations): * Lady in New Brunswick, Canada was extremely depressed after a difficult divorce and felt being on the life’s edge. She was getting scammed left and right on dating apps and was losing hope. She told me that I was the only one that she felt she could trust and talk to, and she probably wouldn’t be here if I ever stopped talking to her. Thankfully, she eventually managed to find a boyfriend and she thanked me for having always been there for her. She still came back to the app to act as a supporter for other lonely souls for a while! * Gentleman in New York, USA felt isolated in a farm and felt he had no real connections with anyone. He shared with me and other users about his life growing various vegetables, but stopped coming on the app for a couple of months. When he came back, he was pleasantly surprised by the app’s development, felt I really believed in my mission to help lonely souls, and became an evangelist for my app :) He posted on several forums on Reddit and engaged in conversations with many users on the app. ...

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: Checkpoint 401 – forward auth server in TypeScript / Deno I wrote a forward auth server in TypeScript and Deno. I've written several forward auth servers before but they have always been specifically written for that application. I wanted something more generalised that I could re-use. What is forward auth? Web servers likes Nginx and Caddy and Traefik have a configuration option in which inbound requests are sent to another server before they are allowed. A 200 response from that server means the request is authorised, anything else results in the web server rejecting the request. This is a good thing because it means you can put all your auth code in one place, and that the auth code can focus purely on the job of authing inbound requests. Checkpoint 401 aims to be extremely simple - you define a route.json which contains 3 things, the method, the URL pattern to match against and the filename of a TypeScript function to execute against that request. Checkpoint 401 requires that your URL pattern comply with the URL pattern API here: https://ift.tt/QmLSTik... Your TypeScript function must return a boolean to pass/fail the auth request. That's all there is to it. It is brand new and completely untested so it's really only for skilled TypeScript developers at the moment - and I suggest that if you're going to use it then first read through the code and satisify yourself that it is good - it's only 500 lines: https://ift.tt/ob34pwt... https://ift.tt/Yu29nxV May 20, 2024 at 12:11AM

Show HN: Drivr – VR with real vehicles [video] This project combines VR with a real vehicle that you are controlling (or is controlling itself, in some scenarios). One advantage this has over traditional VR motion experiences is that your senses all agree with each other, thus greatly reducing the likelihood of motion sickness. The go-kart seen in this video is drive-by-wire and steer-by-wire, so the system will not let the player exit the defined safe area. If a player goes off course, the vehicle will take control, and return them to the start. The autonomous capabilities also allow for games where the player can focus on other objectives other than driving, such as target shooting. No infrastructure is required other than the vehicle and an open place to drive (which honestly has been the most challenging part lately). If you're interested in this project, I'd love to connect! https://www.youtube.com/watch?v=Q76X0cnSGHk May 17, 2024 at 12:49AM
Show HN: A job board that helps you find impactful roles Hi everyone! We wanted to make it easier for people to find high-impact roles across various fields, so we built a job board that highlights relevant opportunities. We’re a nonprofit, so this is completely free. When we say “high-impact”, we mean that we think these roles are relatively likely to lead to substantial positive change in the world. We recognize that there’s a lot of uncertainty regarding this, since although we look into the jobs that we list, there’s no way to be sure which ones will end up being impactful (not to mention that people have different definitions of “high” and “positive” impact). We also know that not everyone prioritizes this kind of impact, especially given how hard the job-search process can be. But, we still think there’s value in trying to aggregate these kinds of jobs, in order to help interested people find them. https://ift.tt/GJEeroR May 16, 2024 at 07:48PM

When I'm sharing code on my blog or elsewhere, I find it really annoying to format and highlight all the words in the code snippet. That's why I made CodeGlow, to make sharing sharing code easy and painless. https://ift.tt/ewq6MFH May 16, 2024 at 08:48PM
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/tpW3nEJ ), 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/2O9cQhk ), 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/tpW3nEJ May 16, 2024 at 10:41PM

Show HN: PuppySignal, an open-source QR Tag for your pets A few years ago, I started working on a side-project just for my own use: a QR Tag for my pets. I decided to open-source it for anyone who might find it useful. The functionality is pretty simple: when you log in, you create a profile for your pet, and a QR code will be generated and linked to its profile. When someone scans this code and decides to share your pet's location, you will receive a notification on your phone with your pet's location, and the person who scanned it will see your contact information. https://ift.tt/wy1jNWd May 13, 2024 at 10:50PM
Show HN: Git Searcher, search commits for an added or removed string Hello all, I created a command line utility called Git Searcher that can find in which commit any line of code was added; it can also find where a line of code was removed. I have found this very helpful for determining where code originated from and for debugging. I hope you find this useful! Many thanks, Sam https://ift.tt/8MShziC May 12, 2024 at 11:20PM
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 06:22PM
Show HN: MinimalChat – A Simple and Customizable LLM Chat Application Hello everyone! I have a hobby project that has become fairly full featured that I figured I would share. The idea of MinimalChat has been to create a project that is a lightweight and dead simple application that can be deployed locally in a few seconds (with docker). While of course also having most of the nice to have features and looking pretty nice. A nice bonus is it a Progressive Web Application so it can be installed like a normal application to your mobile device. It has a full mobile UI. For those using Chrome and Edge you can also locally download, load and host entirely via your browser models like LLama-3-8b with hardware acceleration via WebGPU. It's pretty experimental but it does work! I won't bloat this post reiterating it's features, the GitHub Readme gives a good idea of the application abilities. I know chat applications are a dime a dozen but...here's another one hah! https://ift.tt/HkdGLob May 11, 2024 at 09:19AM
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/cmbqr5P ). 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. If you would like to support my efforts, please consider donating via patreon https://ift.tt/rlhxip4 https://twitter.com/xw4ffl35x/status/1778094355812700635 May 11, 2024 at 02:12AM
Show HN: A web debugger an ex-Cloudflare team has been working on for 4 years Hey HN, I wanted to show you a product a small team and I have been working on for 4 years. https://jam.dev It’s called Jam and it prevents product managers (like I used to be) from being able to create vague and un-reproducible bug tickets (like I used to create). It’s actually really hard as a non-engineer to file useful bug tickets for engineers. Like, sometimes I thought I included a screenshot, but the important information the engineer needed was what was actually right outside the boundary of the screenshot I took. Or I'd write that something "didn't work" but the engineer wasn't sure if I meant that it returned an error or if it was unresponsive. So the engineer would be frustrated, I would be frustrated, and fixing stuff would slow to a halt while we went back and forth to clarify how to repro the issue over async Jira comments. It’s actually pretty crazy that while so much has changed in how we develop software (heck, we have types in javascript now*), the way we capture and report bugs is just as manual and lossy as it was in the 1990’s. We can run assembly in the browser but there’s still no tooling to help a non-engineer show a bug to an engineer productively. So that’s what Jam is. Dev tools + video in a link. It’s like a shareable HAR file synced to a video recording of the session. And besides video, you can use it to share an instant replay of a bug that just happened — basically a 30 second playback of the DOM as a video. We’ve spent a lot of time adding in a ton of niceties, like Jam writes automatic repro steps for you, and Jam’s dev tools use the same keyboard shortcuts you’re used to in Chrome dev tools, and our team’s personal favorite: Jam parses GraphQL responses and pulls out mutation names and errors (which is important because GraphQL uses one endpoint for all requests and always returns a 200, meaning you usually have to sift through every GraphQL request when debugging to find the one you’re looking for) We’re now 2 years in to the product being live and people have used Jam to fix more than 2 million bugs - which makes me so happy - but there’s still a ton to do. I wanted to open up for discussion here and get your feedback and opinions how can we make it even more valuable for you debugging? The worst part of the engineering job is debugging and not even being able to repro the issue, it’s not even really engineering, it’s just a communication gap, one that we should be able to solve with tools. So yeah excited to get your feedback and hear your thoughts how we can make debugging just a little less frustrating. (Jam is free to use forever — there is a paid tier for features real companies would need, but we’re keeping a large free plan forever. We learned to build products at Cloudflare and free tier is in our ethos, both my co-founder and I and about half the team is ex-Cloudflare) and what we loved there is how much great feedback we’d get because the product was mostly free to use. We definitely want to keep that going at Jam.) By the way, we’re hiring engineers and if this is a problem that excites you, we’d love to chat: jam.dev/careers May 10, 2024 at 06:38PM

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/KVPTaFj May 10, 2024 at 12:15AM

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 06:38PM
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: gpudeploy.com – "Airbnb" for GPUs Hi HN, YC w24 company here. We just pivoted from drone delivery to build gpudeploy.com, a website that routes on-demand traffic for GPU instances to idle compute resources. The experience is similar to lambda labs, which we’ve really enjoyed for training our robotics models, but their GPUs are never available for on-demand. We are also trying to make it more no-nonsense (no hidden fees, no H100 behind “contact sales”, etc.). The tech to make this work is actually kind of nifty, we may do an in-depth HN post on that soon. Right now, we have a H100s, a few RTX 4090s and a GTX 1080 Ti online. Feel free to try it out! Also, if you’ve got compute sitting around (a GPU cluster, a crypto mining operation or just a GPU) or if you’re an AI company with idle compute (hopefully not in a Stability AI way) and want to see some ROI, it’s very simple and flexible to hook it up to our site and you’ll maybe get a few researchers using your compute. Nice rest of the week! https://ift.tt/hR7STzr May 5, 2024 at 02:33AM

Show HN: I built a free in-browser Llama 3 chatbot powered by WebGPU I spent the last few days building out a nicer ChatGPT-like interface to use Mistral 7B and Llama 3 fully within a browser (no deps and installs). I’ve used the WebLLM project by MLC AI for a while to interact with LLMs in the browser when handling sensitive data but I found their UI quite lacking for serious use so I built a much better interface around WebLLM. I’ve been using it as a therapist and coach. And it’s wonderful knowing that my personal information never leaves my local computer. Should work on Desktop with Chrome or Edge. Other browsers are adding WebGPU support as well - see the Github for details on how you can get it to work on other browsers. Note: after you send the first message, the model will be downloaded to your browser cache. That can take a while depending on the model and your internet connection. But on subsequent page loads, the model should be loaded from the IndexedDB cache so it should be much faster. The project is open source (Apache 2.0) on Github. If you like it, I’d love contributions, particularly around making the first load faster. Github: https://ift.tt/L58zlPo Demo: https://secretllama.com https://ift.tt/L58zlPo May 4, 2024 at 02:56AM
