Show HN: We built a multimodal AI interviewer for mock system design interviews Hey HN! We’re Jared, Shreyas, and Varun the creators of TechInterviewer. We’re building a product for software engineers to go through an entirely simulated systems design interview. Our AI interviewer, Steve, gives you a prompt and you talk out loud and draw on a whiteboard while Steve guides you through the interview and gives real-time feedback. Check out our demo: https://ift.tt/R5xk9U0 Every software engineer today has to prepare for systems design interviews and have two awful options: pay hundreds of dollars for a single session with a FAANG engineer or follow silently alongside a YouTube playlist. Because there is no instant feedback while practicing, engineers often learn about their most important knowledge gaps during the course of the interview loop. Jared and Shreyas are both senior engineers who have spent 1000s of hours preparing for and administering systems design interviews. Shreyas was an early engineer at Deepgram and spent many years tracking developments in the TTS (text to speech) space. He realized that voice interviews had potential to change the candidate experience when he starting using chatGPT to prepare for interviewing founding engineer candidates at his startup. We’re hoping that having easy access to interview feedback will level the playing field of software engineers at different skill levels. We’re really excited to share this with you all and we’d love any thoughts, feedback, and comments https://ift.tt/ngQvXrM January 19, 2024 at 07:59PM

Show HN: Transitive, an open-source framework for full-stack robotic software After three years in development, I'm thrilled to share Transitive: an open-source framework for full-stack robotic software ( https://ift.tt/NaeARYu ). The Transitive framework makes it easy to build robot cloud portals. Even given all the great open-source tools for web development and device management, building such cloud portals for robots is still not an easy task. There are several reasons for this, but a big one is that robots are different from regular servers, despite many people attempting to tread them as such. They go offline a lot, have limited network bandwidth, and each robot in a fleet may run a different version of software and require a different configuration. Robots also generate a lot of data, some of which needs to be synced in real-time with cloud and web front-ends for processing and visualization, some of which recorded, and some discarded. In addition robots roam insecure areas and are connected over networks outside of the control of the startup, hence requiring tight authentication and authorization. Transitive solves many of these issues. It provides a reliable, real-time data synchronization protocol that operates on top of MQTT, called MQTTSync. MQTTSync seamlessly synchronizes stateful data between robot, cloud, and web, instead of just passing messages. It provides the notion of full-stack packages that implement encapsulation and versioning of software components for all three systems (robot, cloud, and web) and uses MQTTSync's name-spaced data model to reliably communicate and operate, even when different robots run different versions of the package. The robot and cloud components are run in sandboxes to isolate them from the rest of the system, and the web components can be embedded in any web page including existing robot cloud portals. And of course, all this is secured, using SSL for transport-level security, client certificates and JSON Web Tokens for authentication, and authorization based on MQTT topics. Taken together this lays a solid foundation for building new full-stack capabilities with ease. Note that Transitive is not a replacement for ROS, and in fact many of our capabilities run ROS nodes on the robot. Neither is Transitive a fleet management system. It just makes it easy for you to build your own! To learn more about our first release of the self-hosted version, please see the linked blog post. If you just want to try it out quickly please go to https://ift.tt/GiZoank to create a free account, which will also give you some starting credit for try out any of our premium capabilities, such as webrtc-based video streaming, our web-terminal, or file-sync ("Dropbox for robots"). I'll be watching this thread for responses, or you can use the contact info at the bottom of the blog post to get in touch. Would love to hear your feedback! https://ift.tt/fB6ZDAa January 17, 2024 at 11:50PM
Show HN: Browser's internal local routes containing juicy stuff There are internal local routes inside browsers which are used for debugging purposing by developers but one can find a use case for him selves. Play around with it to find something interesting. Here are those internal routes/urls corresponding to the browser. Put it in url bar (omnibox/search bar) and hit enter. chrome - chrome://chrome-urls/ firefox - about:about edge - edge://edge-urls/ I'm pretty sure that most of the browsers have this you can just google like this "[your browser name] internal urls" https://ift.tt/EPRKT9f January 17, 2024 at 01:15AM
Show HN: A minimal working Rust / SDL2 / WASM browser game "Game" is a stretch, but I put together this repo containing a pure Rust app which uses SDL2 and compiles to WASM (and can be run in a browser).

Show HN: Map2Image – Download Beautiful City Maps Hey there, we're excited to share our passion project with you: map2image.com. A haven for those who appreciate the elegance of city maps, i.e. beautiful art merged seamlessly with informative content. Many of my friends are from abroad and lived in various cities around the world. I built Map2Image with the help of a friend to generate images as small presents, hoping the maps would remind them of the bustling cities they once called home! I hope you enjoy them as well! Our goal: offering you well-designed city maps that elevate your home with sophistication. All maps can be downloaded for free and can directly be printed to serve as stunning art on your walls. We've put a lot of heart into this in the past: from trying our luck on Etsy, selling on private channels, evaluating different company structures, and navigating the maze of automated printing and shipping to customers... it didn't work that well and instead of letting this project die, we made a subset of images available for free. For sure the maps are not perfect (yet), but we make fixes occasionally. Also, the website was handcrafted without much Bootstrap knowledge. We will try to improve loading times and usability at some point. So, stay tuned. Happy about feedback & thanks in advance! https://ift.tt/GRY2Klm January 15, 2024 at 01:03AM
Show HN: C port of the (non-super) Star Trek game, incl. WASM for browser/phone Hi HN, I've decided to port the original (non-super) Star Trek game to C since I wanted to try playing the original but wasn't able to find a lot of sources that run on modern machines. Therefore I based this port on Michael Birken's 2008 C# port. This is in contrast to the Super Star Trek game which was far more popular and has a number of sources available on the web. I took some hamfisted measures to allow the Web Assembly version of the game to be played on mobile as well, it's not very pretty but it kind of works. You can tap into the terminal to open your phone keyboard, then the terminal should be visible in the top half while the keyboard can stay open in the lower half. The tips section on the page has some further hints. The port itself is quite crude but I made sure that it is ANSI C89 compliant, because I wanted the game to be able to run on just about anything. For the best effect, I recommend playing the game using the aptly named cool-retro-term. https://ift.tt/tzabxdi This is the best way to play short of hooking up your needle printer as a faux teletype terminal. https://ift.tt/snlMuW7 January 14, 2024 at 01:25AM

Show HN: Conway's Game of Life, but with a gallery of other peoples patterns This is my spin on Conway's Game of Life. I have added the ability to create an account, save grids that you have discovered, and browse the gallery of grids saved by other people and replay them. This project has served as a sandbox for me to practice various aspects of developing a comprehensive web application from scratch. This was my first time developing a full scale web app with [almost] all the features you would expect. I know it is nowhere near perfect in its current state, but I feel it has reached a point of diminishing returns, and therefore my time is better spent focussing on other projects with more potential. I may continue to develop this project further in the future just for fun. https://ift.tt/ikt8qad January 12, 2024 at 01:42PM
Show HN: I built yet another ChatGPT Chrome extension Hey HN, I’m here to introduce you my first of hopefully-many-projects-to-come this year: ReadPal.ai, a chrome extension that let’s you chat with ANY web pages while browsing. Let’s first address the elephant in the room: there are tons of chrome extensions of sorts out there…Why did I choose to work on this? Over the years, I’ve had many projects started that never crossed the finishing line; and also many ideas that’s dauntingly ambitious that I never even started. So I chose this project, in the hope that its moderate size & scope can help me finally exercise the build→ship muscle. And I must say, it has served its purpose. I thought it would just be a weekend project, however, end up dragging it for months…With the pressure of the year-end and the free time in the holiday season, I finally got to the ship phase! During the process of building, testing, and beta testing, I came across two revelations about the product: - Having AI side by side with access to the same information as you is very helpful! It's not just about summarizing long research papers, but even simple day-to-day activities can benefit from it. e.g. asking “is this miso good for making ramen?” on a miso product page on amazon, etc. - Despite a lot of similar extensions, there is still room for differentiation! The average user who isn’t intentionally following the developments in the AI field, can benefit from a tool that simplifies the complexity of various models & prompting techniques, and focuses on providing a user experience that seamlessly integrates with their workflows. There is still a long way to go in terms of the second point. Your feedback would be very helpful with that! Thank you!! https://readpal.ai January 11, 2024 at 09:03PM
Show HN: I built an affordable alternative to Spotify and YouTube Music Premium Hey guys, I had to cancel my spotify premium subscription which was a terrible thing once I like to listen music in loop while coding or at the gym. So I decided to code myself something cool to solve my own problem that makes possible listen music in loop and without ads. I took a night off and started coding something.. so that's how I built Youtube Music Loop. I know many ppl like to listen music but not everyone can afford to pay, so it's a lite affordable version of spotify and youtube premium, where you can: - Keep listen music without ads. - Synch your playlist through all your devices. - Listen music in loops and without ads. - Search for your fav music or just copy and past the link of youtube song (when search api doesn't reach its limit). - Get it as pwa / app in your phone home screen. - Works on pc and laptops, tablets and mobile devices. - Easy and simple to use, no fluffy stuff. It's an affordable option and you pay once and use it forever, which is more than half of youtube and spotify premium subscription price. You check it here: https://ift.tt/AdQu3JD Let me know what you think and improvements you like to see, I have made many improvements as you can see here and here. -Fausto https://ift.tt/AdQu3JD January 11, 2024 at 11:52PM

Show HN: Asymptotic Growth Order Calculator I'm an undergraduate student and for my math honors thesis I'm studying asymptotic growth orders, the kind you usually see written in "big-Theta" notation to describe an algorithm's time/memory usage. The most interesting part was studying how to compute the growth order of the sequence of partial sums of a given sequence - that is, the growth order of (a_1 + ... + a_n), in terms of the growth order of (a_n). So I thought I would make a little web calculator for playing around with this. Enjoy! :-) Some things to try: 1. The sums of the harmonic sequence (1/n) diverge, but can you find a faster-decaying sequence that also has diverging sums? 2. Can you make the growth order log(log(log(n))) using only one register? 3. What happens when you apply Σ⅟ΣΣΣ (applied from right to left) to any growth order, and why? https://ift.tt/ZYoEhLH January 9, 2024 at 11:22PM
Show HN: Dashwave – Fast Android cloud build tool with collaborative emulators Introducing Dashwave Public Beta! Hello, I am Supratik Das, Co-founder, and CTO at Dashwave. I am thrilled to announce the launch of Dashwave, a powerful cloud build and emulation tool for fast and collaborative Android development. It supports all major Android languages/frameworks: Java, Kotlin, React Native and Flutter. Why Dashwave? - The Problem Android developers often struggle with insanely long build times and resource-intensive emulation sessions. They work in close collaboration with product stakeholders and rely on WIP feedback. Since builds, and feedback are slow, this leads to a 'code more, build less' approach, causing debugging challenges due to insufficient testing and productivity losses. Solutions exist but their scope is limited either as a general-purpose build tool or a CI/CD build tool. At Dashwave we are tailoring the entire platform right from the local development stage for the use cases of Android Developers. What is Dashwave? - The Solution With Dashwave, you can quickly onboard your project, fire your local build on Dashwave’s cloud, preview the native emulated app interactively streamed to the browser and share emulation for feedback/demo/anything you want. Don’t believe me? Watch this video where I do all the above three in 5 minutes: https://www.youtube.com/watch?v=uQpmVfyF44o KEY FEATURES Integration with IDEs/Editors: Integrate local code with our build engine using DW CLI. Attach an Android debugger while you build and emulate on our cloud. Cloud Builds: Get fresh build environments with no dependency conflict. Build on powerful cloud nodes tapping parallelization. Supports Java, Kotlin, React Native and Flutter Remote Caching: Dashwave uses Gradle Enterprise grade Distributed Caching to speed up your builds. If a project was built historically by anyone on Dashwave, future users will enjoy cached builds. Build Analytics: Analyse build performance and dev productivity with Builds ROI stats, cache utilisation metrics Cloud Emulation and Previews: Preview your built app on cloud emulators, interactively streamed to your browsers. You can also connect your physical device to Dashwave Cloud to enjoy real device previews. Collaborate: Share your emulated app build as a link to anyone, exchange contextual comments with screenshots and logs to get feedback. Reduce CI Headaches: Use a singular ground for development and CI builds. If it builds on dev, it will build on CI. Security and Privacy: Rest easy knowing that your data and intellectual property are protected by the latest security measures. Visit https://dashwave.io to know more. Join our discord server for help and the latest updates. Start creating your first build on ( https://ift.tt/DqSuV74 ) We can't wait to see what you create with Dashwave! Happy building! https://ift.tt/Pzg58io January 8, 2024 at 09:34PM

Show HN: Fitlock – Block apps until you reach your daily fitness/health goals Introducing Fitlock, the privacy-focused app designed to empower users in curbing screen time and enhancing fitness through the utilisation of Apple Health and Screen Time features. Fitlock's innovative approach involves blocking apps and websites until users achieve their daily health and fitness objectives. Here's how Fitlock operates: users can establish a personalised schedule to block specific apps at chosen times of the day, adjusting the strictness level of the block to suit their preferences. Once the user's schedule is active, the blocked apps remain inaccessible until they successfully meet their health and fitness goals. For instance, a user might set up a schedule to restrict social media apps daily, unlocking them only for 30 minutes each time they reach 2000 steps within the specified timeframe. Beyond its core functionality, Fitlock boasts additional features like progress tracking over time and a range of strictness levels to cater to diverse user preferences. It's worth noting that Fitlock is currently exclusive to iOS, but stay tuned as there are plans to develop an Android version in the near future. I'd love to hear your questions/feedback. https://fitlock.io/ January 6, 2024 at 04:12AM
Show HN: Seedling – A Decentralised Medium Initial version of my decentralised publishing platform for articles and blog posts - like a Web3 Medium. It's open source and [almost] fully decentralised. Runs on the Polygon network. Current version lets authors publish markdown content from their GitHub account and lets users tip articles. No wallet or GitHub account is needed to browse content. Authors link their GitHub account or organisation to their wallet address via oauth and an on-chain user registry, after which they can submit article URLs directly to the on-chain content registry. The content registry ensures only registered users can publish, and only from their registered GitHub account. By adding different hosting options and expanding the feature set, the ultimate goal is to create a platform for independent journalists to publish without fear of censorship or repression, and to fund their journalism through direct tipping, subscriptions and profit sharing models. https://seedling-d.app January 6, 2024 at 04:24AM

Show HN: Hook – a simple graphical C/C++ runtime editor While helping one of my students create and iterate on a game in C using raylib, I realized there was quite a lot of time spent on experimenting with level design and colors, how the player moves, gravity, etc. and a lot of time was wasted making a change, exiting the game, recompiling, running the game, deciding his change wasn't right, and going through the whole cycle over and over. I could tell it was demotivating, and this process was creating a barrier that prevented him from experimenting to his heart's content. I started this project to solve this problem by giving a simple gui to a few core features of lldb through the lldb api. Experimenting with changing colors, where blocks in the level go, how tall the player is, gravity is all now just a simple toggle or text field edit. The variables are modifiable while the program is running. The project is still in its early stages, and so far only targets macOS. https://ift.tt/ag0Q7A8 January 2, 2024 at 06:45AM
Show HN: Cassette, a Personal Programming Language I made this simple language over the past year, and it's time for me to say it's "done" (for now) and focus on other projects. I've struggled to answer the question "what is this language for?" other than "it's just for me" — and that's probably good enough. But I also wanted to make something "complete" that others could use if they wanted to. Writing my own language was an incredibly rewarding experience, and I'd recommend everyone trying it. Let me know if you have any questions or feedback, and please share your own experience if you've also made a language. https://ift.tt/kpuXPFc January 1, 2024 at 03:31AM

Show HN: Scan QR codes to check-in guests registered via Google Forms™ Hi HN! I made a no-code platform for creating physical data collection apps, using QR codes [1]. It does not yet have a self-service config UI though, which limits adoption. That's why I recently released a Google Forms™ add-on for QR code check-in, based on the platform. This focused use-case makes it easy to provide a fully self-service config UI. How it works: 1. Create your Google Form as you normally would [2] 2. Activate the add-on if you hadn't already [3] 3. Craft a confirmation email to be sent to each form responder Upon each form submission, the add-on will send a PDF with a unique QR code (a V4 UUID) to the responder. Have guests present this code at the event, and record check-ins in bulk using the included QR scanner.

Show HN: Meal planning app I built after losing 50kg myself in 2022 1500cals is a calorie and excercise tracking tool that I built after losing 50kg myself in 2022 through simply watching what I ate and starting to exercise. The main "trick" I uncovered is simply to plan meals ahead. It sounds boring, it sounds annoying, but really its such a tiny effort for such outsized and life changing rewards that it should be a no-brainer. The existing tools I found were more focused on tracking after eating which is great in terms of capturing data and measuring over time, but I found really didn’t help me with locking in a routine.

Show HN: Capit – Social Media Image Caption Generator Hey HN! I just recently released my latest iOS App, Capit - it is a simple app built to generate captions for social media posts, all directly from images & video, utilizing gpt-4-vision. Users just choose an image, select a tone, and get 5 great caption options. My latest update adds Profiles to allow you to save your settings for different social media profiles, along with a simple caption editor to let you customize your captions further. The app is a subscription service - but lets you try it for free if you just hit the X button on the paywall. I built the app as my wife runs a small business for which Instagram is a huge traffic generator...but she often gets stumped at what to write in terms of captions, especially when we've been open for years and it feels like you are just recycling content in many cases. Capit isn't really meant to automatically post for you - it is a tool for improving your own creativity. I'd appreciate any & all feedback! https://capit.app December 24, 2023 at 12:49AM

Show HN: Live-ish illustration for TTRPG campaigns My D&D group typically casts music to our TV during sessions, and very occasionally, the default background image lines up nicely with what the party is doing (e.g. a picture of a mountain while we’re exploring a mountain pass). Using Whisper speech-to-text, GPT 3.5, and DALL-E 3, I rigged up something to make that happen automatically. The results are certainly interesting. The images generated are typically much closer to what’s actually going on than the previous example, but get many of the small details wrong. https://ift.tt/WKmtTfO December 21, 2023 at 10:14PM

Show HN: Slack knowledge curator to extract FAQ from discussion threads Hi HN! Excited to share Snowshoe, a Slack bot that transforms your Slack threads into a searchable StackOverflow-style Q&A. Snowshoe automatically curates key discussions from Slack, creating a dynamic, easy-to-navigate knowledge hub. A lot of technical discussions among engineers happen in Slack threads. Yet the unstructured thread makes its inherent knowledge difficult for search and thus the discussion insights aren’t often well documented & maintained. LLM is surprisingly good at summarization & extraction. Thus I think it’s good timing to give it a try. Currently Snowshoe focuses on knowledge extraction in Q&A format. What’s next? I feel like there would be a lot of value in the auto-curated Q&A, e.g. auto question answering, knowledge hub, Slack archive for SEO. Happy to hear your thoughts! https://snowshoe.dev/ December 21, 2023 at 12:21AM

Show HN: Quack Companion – VSCode extension for OSS contribution assistance Hello there, I'm FG (short for François-Guillaume)! I’m building Quack Companion ( https://ift.tt/w3tBx06 ), a tool designed to bridge the gap between project maintainers and contributors in open-source software (OSS). If you've ever contributed to OSS, you're familiar with the challenge: diving into a new codebase, aligning with maintainers' expectations, and making meaningful contributions can be daunting. For maintainers, managing a flood of contributions and providing guidance while maintaining quality is overwhelming. As a contributor to PyTorch & an OSS author, I’ve been on both sides over the years. This challenged me to become a better engineer & team player, seeking ways to facilitate smooth collaborative software development. This is where Quack steps in, as your AI companion for software team alignment. For developers, it's like having a seasoned mentor guiding you through the intricacies of a new codebase, offering live in-line hints based on the project’s guidelines to craft high-quality pull requests. For maintainers, it’s a practical toolset to identify and address workflow inefficiencies and align contributions effectively with project objectives. As code generation gets commoditized, aligning these diverse efforts becomes critical if you wish to convert individual productivity boosts into team velocity. Quack AI is here to solve this alignment, and make collaborative software development scale without losing any efficiency. We're committed to keeping the service accessible and free for OSS communities while we plan to generate revenue from the enterprise suite. The platform (React, Next JS), the IDE extension (VSCode) and the backend API (Python, FastAPI) are licensed under Apache 2.0. You can find a short demo here [1] and the GitHub project here [2]. Our roadmap includes: * offering autocompletion and code chat in the IDE, making the contribution process even more intuitive and seamless; * finalizing the transition of the community version to hostable OSS models; * identifying ambiguities or unspecified aspects of a given project’s guidelines; * developing a Fitbit-like feature for your software development productivity to identify bottlenecks in your workflow. This is still the early days, but we've seen how sharing a "public design doc" with the community can significantly improve the outcome! How was your experience of managing inbound as maintainers? What were your personal hacks to mitigate those challenges? We'd love to hear about how it has impacted your developer life or if you have any feedback about the above. Cheers!

Show HN: Canary Checker – An OSS Kubernetes Native Health Check Platform I am Moshe the Founder @ Flanksource, and today we are releasing canary-checker, an open source, kubernetes native health check platform that provides a unified view of health across the entire stack. Canary checker was born out of the need for platform teams (particularly those running on- premise or on less than perfect infrastructure) to understand the health of applications running on top of the platform. Unlike other solutions such as prometheus blackbox exporter, kuberhealthy, and synthetic testing offered by major cloud providers, our approach goes beyond health collection. Canary Checker enables health aggregation by ingesting alerts from Prometheus, Cloudwatch, Dynatrace, and for running full test suites using tools like K6, Playright, Robot, etc.. This approach provides a unified view of system health without the need to browse through many dashboards. Canary Checker can also replace the need for multiple Prometheus exporters. It empowers you to export metrics from responses across 35+ supported protocols, including HTTP, SQL and Elasticsearch. Something fairly unique to canary-checker is the ability to build stateful checks that use the results of a previous check in subsequent checks to generate metrics around historical data such as logs, logins, and activity stored in db tables. https://ift.tt/P3zRU7W December 19, 2023 at 11:44PM
Show HN: Paradict – Streamable multi-format serialization with schema Hi HN ! I'm Alex, a tech enthusiast. I'm excited to show you Paradict ( https://ift.tt/gruRN3H ), my solution for streamable multi-format serialization. Although JSON, YAML, and TOML are all human-readable, they serve different purposes. For example, TOML is specifically designed for configuration files while JSON is used as a data interchange format. Sometimes an initiative to create a binary version of JSON arises and as far as I know, it ends with an unidirectional mapping of datatypes. There is no silver bullet, yet one coherent solution built from scratch that addresses multi-format (binary and textual) serialization and configuration files would be a step forward. Earlier this year, I accidentally designed a textual data format to represent complex data structures inside a document divided into sections. The project, namely Jesth (Just Extract Sections Then Hack'em), generated an interesting discussion on HN ( https://ift.tt/tSiP5CD ). Out of curiosity, I ran some benchmarks using Jesth, JSON and MessagePack, with and without Gzip compression against a large JSON file downloaded from the web. The benchmarking gave me insights that led to the decision to evolve Jesth's ideas into a new multi-format serialization solution. I designed and built Paradict from scratch to serialize and deserialize a dictionary data structure. Although Paradict's root data structure is a dictionary, lists, sets, and dictionaries can be nested within it at arbitrary depth. A Paradict dictionary can be populated with strings, binary data, integers, floats, complex numbers, booleans, dates, times, datetimes, comments, extension objects, and grids (matrices). There is also a schema-based validation mechanism that can contain programmatic checkers. The binary serialization format is designed with compactness in mind such as Pi with its first two decimal places, the Golden ratio with its first two decimal places, and the date of the funeral of Pope Benedict XVI would each be encoded on two bytes (not counting their respective 1-byte tag which starts each Paradict binary datum). This binary format has two levels of granularity for continuous data stream processing: a datum at the low level, which is in some cases a 2-tuple composed of a tag and its payload, and the message at the high level which is a dictionary data structure. The textual serialization format has two modes: data and config modes. Config mode implicitly treats dictionary keys as strings, removing the need to surround them with quotes, and unlike the colon (:) between a key-value pair in data mode, it uses the equal sign (=) as separator. This textual format has two levels of granularity for continuous data stream processing: a single line of text at the low level and the message at the high level which is a dictionary data structure. Here is a valid Paradict configuration document that contains a "user" section: [user] # no comment id = 42 name = 'alex' birthday = 2042-12-25T16:20:59Z photo = (bin) 54 68 69 73 20 69 73 20 6E 6F 74 20 61 20 70 68 6F 74 6F 67 72 61 70 68 weight_matrix = (grid) 1 0 1 0 0 1 0 1 1 0 1 0 books = (dict) romance = (list) 'Happy Place' 'Romantic Comedy' sci_fi = (list) 'Dune' 'Neuromancer' epitaph = (text) According to the law of conservation of energy, no a bit of you is gone; you are just less orderly. --- Under the hood, Paradict uses Braq ( https://ift.tt/T4geuoB ), the most obvious way to section a document (as shown just above), and Ustrid ( https://ift.tt/2LwcNb9 ), to uniquely generate string identifiers. Paradict is available on PyPI and you can learn more by reading its README, browsing the source code or playing with its tests.

Show HN: Get any piece of Google Earth as a single normalized glTF 3D model Google released an API in May to get fetch 3D Tiles of anywhere on Earth. Using this in standard 3D engines like Blender is tricky because (1) the tiles are in a geographic coordinate system (2) you get a lot of little tiles at varying quality levels I wanted to simplify this so all you need to do is get an API key, select a map region and a zoom level, and get one combined glTF file that you can throw into any engine. Especially if you're just prototyping and want to see how this data looks in your engine before investing in figuring out all the nuances of the API & coordinate system. (Note that the API prohibits offline use, as in you can't distribute a processed glTF file like this. But you can do this preprocessing in memory whenever you're fetching tiles). https://ift.tt/610xo4N December 17, 2023 at 10:07PM

Show HN: Sqlauthz: Declarative permissions management for PostgreSQL I've been working on a little project recently to solve a problem that I've encountered at every job I've ever had, and I'm eager for some feedback. Having super granular roles & permissions in PostgreSQL is desirable, but quite difficult to maintain (particularly at smaller companies without dedicated security/devops/DBA/whatever who make it their business to maintain it). I've thought for a while that having a declarative way to manage them would be really useful and allow more teams to actually make use of sophisticated security features that PostgreSQL offers in their production systems. You can probably see where this is going... I wrote a tool to do just that! It's called sqlauthz, and it allows you to declarative manage your PostgreSQL permissions by writing rules in the Polar authorization language. https://ift.tt/O2VNuxX December 17, 2023 at 12:42AM

Show HN: Bemi – context-aware data change tracking for Prisma Hey HN, we’re Evgeny, Arjun, and Donna - we’re building automatic data change tracking for PostgreSQL and we’re releasing our Prisma integration! The repo is https://ift.tt/qhOBLfI and our home page is https://bemi.io . We've built robust data tracking systems before, for example at companies that hadn’t implemented an event-sourced architecture from the get-go and needed to scale with traditional transactional databases. We’ve since learned that the tech is useful to lots of others. We’ve gone full-time on Bemi now and have been following that demand to build a general-purpose tracking solution that can be used for a wide range of use cases such as reliable audit trails, surfacing data to customer support, reverting changes made in an API request, or testing different application states. We’ve built Bemi to be lightweight and secure. It takes a practical approach to achieve the benefits of event sourcing without requiring rearchitecting existing code, switching to highly specialized databases, or using unnecessary git-like data versioning abstractions. We want your system to work the way it already does with PostgreSQL to allow keeping things as simple as possible. We plug in at both the database and application levels, to get reliability, performance, and also a comprehensive understanding of every change. On the database level, we ingest changes using change data capture (CDC). On the application level, our library allows passing application context and metadata to the write-ahead logs (WAL) automatically. We then stitch the change data together and store it in a structured format in a destination cloud PostgreSQL. We plan to charge for compute if you’re a company storing >1M changes a month. If this is something that seems interesting to you feel free to play around with it or message us! We’re still early and it’d be amazing to get HN’s feedback. What do you think HN? https://ift.tt/qhOBLfI December 15, 2023 at 11:01PM

Show HN: Octopus – a directed acyclic graph for app development Directed acyclic graphs are muched discussed in comp-sci, but octopus appears to be the first reusable, turnkey, ready-to-wear, off-the-shelf implementation of a DAG for application development, in any language, that I'm aware of. This is remarkable because DAGs hit a sweet spot in the middle of the three common programming paradigms (OO, event-driven, functional). Let's have a DAG as the top-level structure of our applications. Data-fetching and onChange handlers live in DAG nodes, next to the data they act on. The UI flows out from the DAG with fine-grained reactivity. Our app state is effortlessly consistent, because any outside change (user action, api result) unleashes a graph traversal. Our UI components become much simpler, because they just need to dumbly reflect values in the graph. I'm putting this up for a second time. Absolutely no-one bit the first time, which can't be right :-) https://ift.tt/fzVS0FJ December 15, 2023 at 12:06AM
Show HN: Gait Analyzer When ever I visit my spine doctor, the first thing they ask me to do is to walk for checking my gait. I've been wanting to analyze my gait myself for a long time and only now its been possible due to accessible & efficient ML/AI and the ability to run complex models on local computer. Gait abnormalities can be attributed to various musculoskeletal and neurological conditions and so gait analysis is being used as an important diagnostic tool by doctors. Automated gait analysis requires expensive motion capture or multiple-camera systems. But with Gait Analyzer one can analyze their gait in comfort and privacy of their home on their computer. Gait Analyzer implements the algorithm published in the paper titled Automated Gait Analysis Based on a Marker-Free Pose Estimation Model - https://ift.tt/oHxQ5g2 . This algorithm for gait analysis is shown to be as reliable as a motion capture system for most scenarios. Gait Analyzer further uses Llama 2 large language model to interpret the gait data to the end user in simple terms. You can test Gait Analyzer by uploading a short side-view video of you walking. In case you want to run it locally in your computer, It's available on docker and its open-source. I'd appreciate your feedback to improve Gait Analyzer. https://ift.tt/G1PzSw2 https://ift.tt/N3sJrAO December 13, 2023 at 11:35PM
Show HN: Visualize rotating objects from the 4th, 5th, nth dimensions Ever since I remember I had a lot of curiosity regarding hyper dimensional spaces. Picturing higher dimensions, such an impossible yet exciting idea... So years ago I came across a small GIF of a tesseract. Since then it left me wondering how cubes from even higher dimensions would look like... Years passed and I became a software developer, decided to tackle the problem myself and ncube was the result. ncube allows you to visualize rotating hypercubes of arbitrary dimensions. It works by rotating the hyperdimensional vertices and applying a chain of perspective projections to them until the 3rd dimension is reached. Everything is generated in real time just from the dimension number. The application is fully free and open source: https://ift.tt/rRvlS36 .

Show HN: QA GPT – Write UI tests in plain English powered by GPT-4-Vision Hey HN, QA GPT enables engineers and QA teams to write UI and functionality tests in plain english. As engineers, we sometimes get a little lazy when it comes to testing the functionality of our changes. It's hard to switch from coder hat to user hat. However, a single bug can significantly impact users experience and satisfaction. Errors found in production aren't just a nuisance; they're costly. The later a bug is discovered, the more expensive it becomes to fix. I built QA GPT as a proof of concept to make writing UI/functionality tests really easy. It's super simple - just write your test case in plain english and run it. For example: - "Test the new sharing functionality by signing in, selecting a user, and clicking share." - "Log in and try adding a product to the cart" - "Create a new card, view the number of the card, and verify the digits match the face of the card" Let me know what you guys think https://ift.tt/KsyCfH4 December 13, 2023 at 02:54AM
Show HN: RΞASON – Open-source TypeScript framework for LLM apps Hi HN! RΞASON is an OSS Typescript framework for developing LLM apps that uses Typescript's interfaces to get structured output from an LLM. While there are other TS LLM frameworks, I think RΞASON fills a unique space in the market: it's laser-focused on only three areas and, most importantly, actively stays away from pre-made prompting & retrieval. I've been in the LLM space since GPT-3 originally came out, and I've always had problems with other frameworks, such as LangChain. I dislike that they focus a ton on out-of-the-box prompting & pre-made agents — I , as the dev, should be the one in charge of it. My belief is that LLMs are a new primitive that programmers can use — not a new way to program; it's still up to the programmer to do the right thing & create the right abstractions. Therefore, it's the developer's job to learn the new concepts that come from this new primitive, such as prompting & retrieval. I see a similar analogy here with ORMs & SQL. What RΞASON helps with is in areas that don't differentiate your app: getting structured outputs, handling streaming, and observability. The goal of RΞASON is to make creating great LLM experiences easier. We try to accomplish this by simplifying the hard stuff & maximizing performance — decreasing as much as possible the TTUB. RΞASON is OpenTelemetry compatible — which allows observability in almost any tool (Zipkin, Jaeger, paid solutions, etc.). I'd really love to hear feedback about RΞASON! It has been a hobby project for the last months and I'm super curious to what y'all will think. By the way, contributions welcome! https://ift.tt/ro52HTV December 13, 2023 at 01:05AM
Show HN: I built an OSS alternative to Azure OpenAI services Hey HN, I am proud to show you guys that I have built an open source alternative to Azure OpenAI services. Azure OpenAI services was born out of companies needing enhanced security and access control for using different GPT models. I want to build an OSS version of Azure OpenAI services that people could self host in their own infrastructure. "How can I track LLM spend per API key?" "Can I create a development OpenAI API key with limited access for Bob?" "Can I see my LLM spend breakdown by models and endpoints?" "Can I create 100 OpenAI API keys that my students could use in a classroom setting?" These are questions that BricksLLM helps you answer. BricksLLM is an API gateway that let you create API keys with rate limit, cost control and ttl that could be used to access all OpenAI and Anthropic endpoints with out of box analytics. When I first started building with OpenAI APIs, I was constantly worried about API keys being comprised since vanilla OpenAI API keys would grant you unlimited access to all of their models. There are stories of people losing thousands of dollars and the existence of a black market for stolen OpenAI API keys. This is why I started building a proxy for ourselves that allows for the creation of API keys with rate limits and cost controls. I built BricksLLM in Go since that was the language I used to build performative ads exchanges that scaled to thousands of requests per second at my previous job. A lot of developer tools in LLM ops are built with Python which I believe might be suboptimal in terms of performance and compute resource efficiency. One of the challenges building this platform is to get accurate token counts for different OpenAI and Anthropic models. LLM providers are not exactly transparent with the way how they count prompt and completion tokens. In addition to user input, OpenAI and Anthropic pad prompt inputs with additional instructions or phrases that contribute to the final token counts. For example, Anthropic's actual completion token consumption is consistently 4 more than the token count of the completion output. The latency of the gateway hovers around 50ms. Half of the latency comes from the tokenizer. If I start utilizing Go routines, might be able to lower the latency of the gateway to 30ms. BricksLLM is not an observability platform, but we do provide integration with Datadog so you can get more insights regarding what is going on inside the proxy. Compared to other tools in the LLMOps space, I believe that BricksLLM has the most comprehensive features when it comes to access control. Let me know what you guys think. https://ift.tt/Yo9RkhU December 12, 2023 at 12:26AM
Show HN: MyYogaFlow – Online Yoga Instructor Hi fellow hackers :) I am an indie hacker based in Switzerland who has been tinkering around with many side projects. Most of the things I developed were for myself or just to get familiar with a specific technology or piece of software. I never really deployed anything so far. Not too long ago, my SO and me bought a deck of cards with different yoga poses on them. Since we both work from our office chairs more than 8 hours a day, we wanted to do something for our body and this is where the yoga idea originated from. After the first 10 minutes of reading through the leaflet and another 30 minutes of choosing the poses and putting them in a somewhat meaningful order, we finally started with our own yoga session. It was clear to me: this is not something my SO wants to do every day. Doing the same order of poses every day wasn't an appealing alternative either. Away with the cards and on the lookout for an alternative again. Hence I started developing an application for us, that automatically generates a yoga session. It shows the poses one by one and guides you through the session. Each session is unique, which makes it more interesting over the days. The app even lets you create your custom flow that you select or it chooses among poses that fit your experience level just right. I have recently launched this application and made it publicly available. It is working (in most of the cases) and we are pretty happy about how it turned out. We used it many times in our lunch breaks or after a stressful day to calm down. I would be more than happy to get some feedback on it and some pointers on what to improve or focus on next. https://ift.tt/TLWnK5X December 10, 2023 at 08:32PM
Show HN: Fine-grained stylistic control of LLMs using model arithmetic We developed a new framework that enables flexible control of generated text in language models. By combining several models and/or system prompts in one mathematical formula, it lets you tweak your style and combine model outputs with ease. A handy tool for those working with LLMs, looking for more fine-grained control of stylistic output. More details in our paper: https://ift.tt/v6uEk7y . Feedback and potential applications are welcome. https://ift.tt/RV0hxdf December 10, 2023 at 02:27AM
Show HN: wallstreetlocal – View investments from the world's biggest SEC filers Hello Hacker News! My name is Anonyo, and I am a seventeen-year-old from Southeast Michigan. This is wallstreetlocal, my passion project for the last year. The United States Securities and Exchange Commission (SEC), forces institutional money managers whose portfolios surpass $100 million to quarterly update the SEC website with their latest investments. These money managers, known as 13F (the form type of the report) filers, are the biggest investors in America, and the law forces them to publicly reveal their investments. The problem I found was that SEC filings are cumbersome to find and view. To remedy this, wallstreetlocal saves and formats SEC data by bulk in an easily accessible format. Other websites do the same thing wallstreetlocal does, but wallstreetlocal places an emphasis on stock data. You can compare prices over time, view gains, and even download the data yourself to make any conclusions you wish. For as many stocks as possible, wallstreetlocal provides accurate, recent data to accompany the filings. As of current, there are 850,000 companies in the search database, 30,000 stocks in the stock database, and about 50 filers queried (equates to a couple million lines of JSON, requested by myself alone). By exploring the website, you can see the resources I used, check out some notable money managers I listed, and download any data that suits you. All for free. I plan to open-source this project someday, but I just wanted to get it released for now. The stack uses FastAPI for the back-end, and Next.js for the front-end. The back-end is hosted on a VM using Docker for the different microservices, and the front-end on Vercel. I made this project to better democratize SEC filings, and also to get some experience on my hands. I love computers, and one day hope to change the world through startups. In the comments, I'd appreciate any and all advice, as well as feedback on how to improve the site. Thanks. https://ift.tt/rBUoSvW December 9, 2023 at 11:26PM
Show HN: Open sourcing Restly – GPT-4 powered tutorials from your OpenAPI spec Hi HN - Marius (mbuleandra) and I built Restly as a side project. Restly generates a user-friendly tutorial against any OpenAPI spec. While building public-facing APIs, we found that writing these guides by hand took a lot of work. Many OpenAPI specs were too large to send to GPT-4 / Claude directly, and even when we could send them, we experienced lost-in-the-middle and hallucination issues. The project is very alpha but works against the Vocode API when we specify well-defined goals. Let us know your thoughts; we would love your contribution to the project!

Show HN: We've built an Open Source plugin to make using AI easier for VFX Hi, I’m Bryan Lyon, the CTO of DeepMake. We’re making plugins for VFX software suites (Right now we have a pre-release of our After Effects plugin ready) that enable you to use Open Source AI tools without leaving the workflow. It makes all the AI tools work just like another plugin in the VFX software. In the past, I worked on VFX adjacent AI and was more than once asked to make AI tools easier to use so the VFX experts could use them. In many cases my job was little more than making it easy to install and make sense to use. After writing dozens of “one-off” scripts that made an AI tool usable I decided there should be a better way. To that end we’ve simplified the process. Right now our public release is still not the easiest to install, but once you’ve installed one plugin and the backend, installing new plugins is as simple as extracting a zip file or cloning a repo (and we’re going to make it even easier). Our target audience isn’t non-technical people, but rather people who don’t have the time or experience to go through installing an AI tool which may not even include an easy way to send your own data through the pipeline. We hope to make VFX easier for people who can’t really do VFX now due to either a lack of time or experience. We also want to make VFX more powerful for VFX experts. We’ve built the backend to make plugins extremely easy to make and hope that the community will be able to take advantage of an easy way to integrate with VFX tools. IN the spirit of open source we’ve released our code as open source (We’re cleaning up the AE plugin side, but it’ll be released too). We plan on monetizing based on managing massive plugins across compute farms for big VFX shops and other features that benefit those larger teams, the core of the system will remain open source and freely available. So far, we’ve released a Stable Diffusion plugin, and have more including Masking, Super Resolution, and more coming up in the pipeline. I hope you like our software and look forward to hearing from you. https://ift.tt/CdJRq5P December 9, 2023 at 03:15AM
Show HN: Open-Source AI Adventure Game Hi HN! I'd love your feedback for this AI storytelling game. Remember when you used to read choose-your-own adventure books as a kid? We're trying to re-create that. The site lets you create adventures by seeding them with parameters that end up feeding LLMs: title, genre, writing style, etc. Once you've done that, you can play your book like a game: with custom chapters, illustrations, voice narration, choices, and dice rolls. We’re really into the idea of merging the open-ended generative AI with goal-directed story arcs that the game author can control. Everything is open source (links below) and we’d love your contributions & ideas. I know there's a lot of great work in this space, and the whole team that built this is eager to learn.

Show HN: Online RPG Game with AI being dungeon master Hi I've created a text-based RPG game in which you can experience different adventures and play interesting characters while the AI acts as a real time DM/story teller. There are multiple ways to interact with AI: 1) Input free will move 2) Input default move (affects resources) 3) Post a question to DM Also one more cool feature is that you can create your own adventure via simple form. Add scenes, add characters and make it public so other players are able to test it. I also plan to have 'competetive' side where players will pay some small fee to creators in crypto depending on community, and leaderboards can determine price pool reward distribution. But thats for future. Check it out and tell me what you think guys :) https://v3rpg.com https://ift.tt/FEZWnNQ December 7, 2023 at 01:51AM
Show HN: Lume – automate data mappings using AI Hi HN! I'm Nicolas, co-founder of Lume, a seed-stage startup ( https://www.lume.ai/ ). At Lume, we use AI to automatically transform your source data into any desired target schema in seconds, making onboarding client data or integrating with new systems take seconds rather than days or weeks. In other words, we use AI to automatically map data between any two data schemas, and output the transformed data to you. We are live with customers and are just beginning to open up our product to more prospects. Although we do not have a sandbox yet, here is a video walkthrough of how the product works: https://ift.tt/q5eRcEu?... . And, here is our documentation: https://docs.lume.ai . We would love to get you set up to test it, so please reach out. Using Lume: we do not have self-serve yet. In the meantime, you can request full access to our API through the Request Access button in https://www.lume.ai . The form asks for quick information e.g. email so that I can reach out to you to onboard you. Please mention you came from HN and I’ll prioritize your request. How our full API product offering works: Through Lume’s API, users can specify their source data and target schema. Lume’s engine, which includes AI and rule-based models, creates the desired transformation under the hood by producing the necessary logic, and returns the transformed data in the response. We also support mapper deployment, which allows you to edit and save the AI generated mappers for important production use cases. This allows you to confidently reuse a static and deterministic mapper for your data pipelines. Our clients have three primary use cases - Ingest Client Data: Each client you work with handles data differently. They name, format, and handle their data in their own way, and it means you have to iteratively ingest each new client's data. - Normalize data from unique data systems. To provide your business value, your team needs to connect to various data providers or handle legacy data. Creating pipelines from each one is time consuming, and things as small as column name differences between systems makes it burdensome to get started. - Build and maintain data pipelines. Creating different pipelines to that map to your target schema, whether for BI tooling, downstream data processing, or other purposes, means you have to manually create and maintain these mappings between schemas. We're still trying to figure out pricing so we don't have that on our website yet - sorry, but we wanted to share this even though it's still at an early stage. We’d love your feedback, ideas & questions. Also, feel free to reach out to me directly at nicolas@lume.ai. Thank you. https://www.lume.ai/ December 6, 2023 at 11:07PM
Show HN: Frogtab – Private, peaceful task management Hi HN! I'm excited to share the task manager that I've been building and relying on for the past 9 months I started developing Frogtab after a particularly busy period at work, where a large number of ad-hoc tasks would need my attention each day. What I Initially tried was a single (long!) checklist of outstanding tasks, but I found that too overwhelming to look at all day long. Then I tried scheduling tasks based on when I expected to complete them, but that also required too much cognitive load - I only had the capacity to bucket tasks into "today" and "not today" And so Frogtab was born. Originally as a Google doc, then later as a rudimentary web app with some simple automation. The automation was there to nudge me towards good habits, e.g., grouping all my outstanding tasks at the beginning of each day and requiring me to consciously choose which tasks to tackle that day. I subsequently refined the system a little, but the core mechanic has been serving me well ever since! More than the benefits I've gotten from using Frogtab at work, it's been really fun to develop Frogtab into a form that is usable - dare I say enjoyable - by other people too. Thanks to feedback from the awesome community at Bear (bearblog.dev) and also from sharing an early version here on HN, I've been able to make a whole host of improvements to Frogtab Highlights include: - Support for a weekly routine, aka recurring tasks - Data export and import, including auto-backup in supported browsers - Ability to receive tasks sent from any device - Dark theme - Keyboard shortcuts - Full docs at frogtab.com/help As I've been developing Frogtab, one of my primary concerns has been data privacy. Frogtab stores data in your bowser and doesn't require an account. Also, Frogtab does not use cookies, collect PII, serve ads, or track you in any way. It's entirely free to use and fully open source - the code is at github.com/dwilding/frogtab If you try Frogtab, I hope that you have a great experience! I would love to hear any feedback/suggestions, thank you :) https://frogtab.com/ December 6, 2023 at 04:27AM
Show HN: Solving NYT Connections with ChatGPT Just for fun I decided to see if I could use chatGPT to solve NYT Connections word puzzles. It uses a pretty straightforward BFS search in which the LLM is first prompted to generate several possible groupings of four related words, and then a different prompt is used to evaluate the soundness of each of those groupings. This approach seems to be able to produce the correct solution somewhat less than half the time. Some observations: * For whatever reason, chatGPT-4 seems to be a bit worse than 3.5 at generating Connections groupings. I haven’t tested systematically so maybe this is just some small sample size bias. But at the very least it isn’t obviously better * It really struggles with the “words that can fill in the blank” style groups. Often it will correctly come up with the right category (e.g. “words that can precede `cheese`”) but will only be able to identify 2 of 4 words in that grouping * It frequently generates very vague categories (“words that can be nouns”) despite nothing like that appearing in the proposal prompt. Also it will still sometimes score them highly, despite there being several explicitly examples in the value prompt disallowing these types of categories If you have any idea for how to improve this, please let me know (or send a PR)! https://ift.tt/MoKIdiT December 6, 2023 at 01:41AM
Show HN: Dropbase – Build internal web apps with just Python Hey HN, I’m Jimmy, co-founder of Dropbase ( https://www.dropbase.io ). We are an internal tools builder for Python developers. All you have to do is import any Python scripts/libraries, declare UI components, and layer app permissions so you can share them with others. We’re a middle ground between Airplane and Retool—simpler UI creation than Airplane, more code-centered than Retool. UI building is declarative and you can bind Python scripts/functions to UI components. You can write Python scripts/functions using our App Studio with support from a Python Language Server Protocol (LSP) for linting. Since the self-hosted worker directly references .py or .sql files in the filesystem, you can even write them on VSCode directly or import any other Python script or library. Our app layout is highly opinionated to speed up app building. Instead of an open canvas for UI building, we just give you a main table view and a widget sidebar. This approach significantly reduces app-building time while still covering what most tools need: see some data and take actions based on it. It’s not flexible enough to do absolutely anything, but that’s the point—there’s a tradeoff between flexibility and speed. Dropbase gives you most of what you need, plus speed! A neat feature we are experimenting with to build admin panels fast is “Smart Tables”. We convert any SQL SELECT statement (even across multiple joins and filters) into an inline editable table, like spreadsheets, without any additional code. We have a hybrid hosting model that combines a self-hosted client and a worker server, with a backend API for app/component definitions hosted by us to simplify pushing feature updates. The worker server sits in your machines so your sensitive data doesn’t leave your infra. We’re Python-centric for now, but plan to add support for Rust, Go, and others later. We made a few demo videos building common tools: - Customer approval tool: https://youtu.be/A1MIIRNkv3Q - Data editing tool (with Smart Table): https://youtu.be/R1cHO9lMRXo To try Dropbase, create an account at https://app.dropbase.io and generate a token, then follow these instructions for local setup: https://ift.tt/i39gf5F . We are very early so we're really excited to get your feedback, especially on our approach to tools building with Python! My co-founder Ayazhan and some of our teammates will be around to answer questions. https://ift.tt/KoZdNJ1 December 5, 2023 at 11:55PM

Show HN: Satounki – Self-hosted temporary elevated access management service I was reading through the comments on this HN post last night[1] which inspired me to share this project here today. I've been working on Satounki since I got laid off last month. It's the culmination of a lot of experience building similar ad-hoc internal tooling at various places throughout my professional career. Satounki already includes: * AWS support * GCP support * Cloudflare support * Auto-generated Terraform providers from the Rust API * Auto-generated Typescript client wrapper from the Rust API * Slack bot for request notifications, approvals and rejections * CLI for requests, approvals and rejections * Dashboard for exploring policies, requests and stats The scope of this project is pretty big and I'm looking for contributors; if you know Rust, Go, Typescript, Nix, or even have an interest in them, take a look and see if this is something that you might like to work on!

Show HN: Audio plugin for circuit-bent MP3 compression sounds I made MAIM, an open-source audio plugin that uses real MP3 encoders to distort the sound. I've also added knobs that let you "circuit bend" the encoders, changing parameters that would normally be inaccessible to the user to get strange glitchy sounds. The plugin lets you switch between two MP3 encoders, since under the MP3 standard, the specifics of what to lose in MP3 lossy compression is left up to the encoder. The encoders are LAME, the gold standard for open-source MP3 encoders, and BladeEnc, an old open-source MP3 encoder that has a really bubbly sound and was fun to work with. I'd love any feedback, and I'll be around to answer questions! https://ift.tt/PkUE4Hg December 3, 2023 at 11:31PM
