Show HN: Audiocube – A 3D DAW for Spatial Audio I’ve recently released my solo project Audiocube I wanted to make a 3D DAW, where spatial audio, physics, and virtual acoustics are all directly integrated into the engine. This makes it easy to create music in 3D, and experiment with new techniques which aren’t possible in traditional DAWs and plugins. I’d love to get any feedback on this software (Mac/Windows) to make it better. You can download it for free through the website. Thanks, Noah https://ift.tt/JTRzLKb January 30, 2025 at 06:42PM
Show HN: ENT Stack – Full-Stack TypeScript Starter Hey HN, I wanted a simple and batteries-included way to start my full-stack TypeScript projects so I built ENT Stack - a monorepo with Express, Next.js and tRPC. It covers the basics - code sharing (between backend and frontend), auth, DB, validation, state management, i18n, logging, mailing, testing, CI/CD and infra. Its focus is to be minimal, flexible, and scalable. It uses proven libraries (Drizzle, Playwright, TanStack Query, Tailwind, Zod, Zustand ...) with custom authentication, authorization and i18n solutions that are easy to modify or replace. The project also contains an NPM package, so new projects can be created with one command: - pnpm create ent-stack@latest https://ift.tt/sdrNO1v January 30, 2025 at 10:39PM
Show HN: Vogent – Better Building Blocks for Voice AI Hi HN! Excited to share some stuff we’ve been building. We spent the last year building voice agents to automate individual call tasks for companies with large call centers. The STT-LLM-TTS-VAD cycle is mostly solved at this point, but the last-mile problem for making these agents performant was frustrating. We ended up building a lot of band-aids, and we decided to put them together into their own end-to-end product. Vogent is a platform for building and serving Voice AI agents, with a focus on providing higher-level building blocks that make it easy to get a voice agent working quickly. You can check out the docs at https://docs.vogent.ai It supports the typical design process of a voice agent (choosing/prompting a model, selecting a voice, and hosting on a phone number or accessing via API), but it has additional pieces that make voice agents performant quickly, like (among other things): - A drag-and-drop agent builder Under the hood, this involves feeding the model only context relevant to the goals of the current node (e.g., asking a particular question and probing conversationally for the answer), while giving it the ability to call a function with the outcome once the goal is achieved to transition to the appropriate next node. This makes it easy to build voice agents that need the structure of a multi-step talk track with the flexibility of accomplishing each task conversationally. - Voices that are trained to spell Off-the-shelf voices (e.g. Eleven, Cartesia) sound much more artificial when they spell. It might sound like an edge case, but this killed almost every engagement we had. We ended up recruiting Upworkers with different accents, having them spell a few thousand phrases, and training our own voices by modifying open-source architectures. Choose “Carlos” for a spelling-optimized voice right now; we’re adding a lot more soon. - An IVR detection model This detector uses the audio stream to predict whether a line came from an IVR or a human, and switches between different LLMs based on the result (so you can have independent IVR navigation and conversational models). - Model versioning and counterfactuals Vogent enables model versioning and testing against past dials within the product. Any feedback would be appreciated. Please also feel free to join our Discord: https://ift.tt/6ufNhKc https://www.vogent.ai/ January 29, 2025 at 10:09PM
Show HN: Mcp-Agent – Build effective agents with Model Context Protocol Hey HN, I spent my xmas break building an agent framework called mcp-agent [1]( https://ift.tt/cs9ThJO ) for Model Context Protocol [2]. It makes it easy to build AI apps with MCP servers, and implements every pattern from the popular Building Effective Agents blog [3] as well as OpenAI’s Swarm [4]. I’m sharing it early to get community feedback on where to take it from here, and to ask for contributions. For those who aren’t familiar with MCP, I think of it as a standardized interface to let AI communicate with software via tool calls, resources and prompts. mcp-agent provides a higher level interface to build apps with MCP. It handles the connection management of MCP servers so you don’t have to. It also implements the Building Effective Agents patterns: - Augmented LLM (an LLM with access to one or more MCP servers) - Router, Orchestrator-Worker, Evaluator-Optimizer, and more - Swarm The key design principles are composability and reusability – every pattern is an AugmentedLLM itself, so you can chain them into more complex workflows. Some background: I worked on LSP [5] and language servers at Microsoft, and saw firsthand how standards and protocols can revolutionize developer workflows. Before LSP every IDE had its own esoteric ways of providing language services. LSP changed all that, and arguably made every language server better, since they can focus on improving a single implementation for all clients. I think AI development is in a similar pre-LSP space right now. There are tons of frameworks [6], every model provider has its own way of handling messages, tool calls, streaming, etc. I really think we need a protocol to standardize these patterns. Pretty soon every service is going to expose an MCP interface, and mcp-agent is about letting developers orchestrate these services into applications (i.e. build “MCP apps”). This can cover any use of an AI model that needs to interact with the world around it: - RAG pipelines and Q&A chatbots - Process automation via AI workflows/async tasks - Multi-agent orchestration, with human in the loop The repo contains examples [7] to build RAG agents, streamlit apps and more. There’s a lot left to build, like streaming support, server auth and tighter integration with MCP clients. But I wanted to share early in the hopes that you can guide me: - If you find this useful, please let me know. If it’s useful to you, I will dedicate all my time to improving it. - I really welcome contributions. If you want to collaborate, please reach out on github to help take this forward. I want to help standardize AI development, so developers a few years from now can look back with horror at the pre-MCP days.

Show HN: I built a SaaS thanks to my wife I’m Michał, and I’d like to share with you the journey I went through with my wife and how, thanks to her, we built our first SaaS, PDFBolt ( https://pdfbolt.com ). I’ve been a developer for over 10 years. In 2020, I decided to build a side project to learn all aspects of app development—deployment, authentication, payments, frontend, landing pages, etc. While looking for project ideas, I came across the Indie Hackers community, where I found a simple HTML-to-PDF API project. The creator mentioned a lot of interest in it and that it was generating revenue. I thought I’d build something similar myself and learn a lot in the process. But it wasn’t easy at all. After working from 9 to 5, it’s hard to spend another few hours in front of the computer in the evening. What about other responsibilities? Groceries, cooking, cleaning, hobbies, spending time with my wife? Still, I tried, very slowly. I had breaks lasting several months, and at one point, due to mental health issues, I practically stopped working on the project altogether. My wife worked as a physiotherapist but, due to difficulties in her job, decided to switch to IT with my help, starting as a manual tester. She did it very quickly (maybe six months) and immediately found a job. In mid-2024, she started asking about my old project and insisted that we finish it. Thanks to her enthusiasm, we managed to do it very quickly. I focused on the backend, and she, in addition to testing, handled the entire frontend and landing page. Around the same time, we also adopted a dog from a shelter, which added a lot of positive energy to our lives and helped us stay motivated. In early January 2025, we officially launched the project. It’s been a long journey, and we don’t have any customers yet—we don’t even know if we will, as we have no idea about marketing :) But we’ve learned a lot and are already happy with the journey itself. As for the technical aspects, the app uses: Backend: Kotlin, Spring Boot, Postgres, Redis Frontend: React, Next.js, Docusaurus Auth: Firebase Hosting: Render (the app is Dockerized) Cloudflare R2 for file storage PDFs are generated using Chromium via Playwright. If you have any questions about the tech stack or anything else, feel free to ask! I’ll be happy to answer. Any feedback or criticism will be greatly appreciated. Thank you! :) https://pdfbolt.com/ January 30, 2025 at 12:54AM

Show HN: A new native app for 20 year old OS X A few of us here are probably familiar with the original Xbox modding scene and the iconic xbins FTP server. Recently, I came across an amazing tool called Pandora by Team Resurgent [0], which got me thinking about how incredible something like this would have been 20 years ago. Just to clarify, I had no involvement in creating Pandora—I’m just inspired by their work. For those who aren’t familiar, getting access to xbins involves a rather dated process. You need to connect to a channel on an EFnet IRC server, message a bot for temporary credentials, then plug those credentials into your FTP client to access xbins. Pandora (and my app) simplifies this entire workflow into a single click. Inspired by Pandora, I decided to build my own take on what this dream tool might have looked like back in the day. I wrote a native Mac app on original hardware—an Intel iMac (20-inch, 2007)—running a 20-year-old operating system, Mac OS X 10.4 Tiger. This was my first foray into native Mac app development, though I’ve done some iOS development in the past. The result is Uppercut [1], and the source is available on GitHub [2]. For the development process, I used Claude to help with a lot of the coding, especially since I was constrained to Xcode 2.5 and the pre-“Objective-C 2.0” features available at the time. I had to be very specific in prompting Claude to avoid newer features that didn’t exist back then. Since the majority of Objective-C code out there comes from the era of iOS development (which relied heavily on Objective-C 2.0 until the arrival of Swift), this was a unique and challenging exercise in retro development.

We’ve spent over a decade working in innovation labs at major tech companies, but our true passion lies in crafting tools that we genuinely want to use every day. With Actionate, we’re not just integrating CI/CD into JetBrains; we’re leveraging the powerful building blocks provided by JetBrains and GitHub Actions to create new, transformative functionality. Our MVP (Minimum Viable Product) focuses on the most essential features we find critical for a smoother workflow, but the goal is to push beyond typical CI/CD boundaries and empower developers in ways that haven’t been possible before. If this vision resonates with you, we’d love for you to check out Actionate and let us know what you think—good or bad. We thrive on community input, and your feedback will shape our roadmap as we continue expanding on what’s possible inside the IDE. Thanks for reading, and I hope Actionate helps you take your GitHub Actions workflow to the next level! https://ift.tt/ICk7vrM January 26, 2025 at 01:53AM

Show HN: Snap Scope – Visualize Lens Focal Length Distribution from EXIF Data Hey HN, I built this tool because I wanted to understand which focal lengths I actually use when taking photos. It's a web app that analyzes EXIF data to visualize focal length distribution patterns. While it's admittedly niche (focused specifically on photography), I think it could be useful for photographers trying to understand their lens usage patterns or making decisions about lens purchases. Features: Client-side EXIF data processing (no server uploads/tracking) / Handles thousands of photos at once / Clean visualization with shareable summaries This tool supports most RAW formats, but you might occasionally encounter files where EXIF extraction fails. In such cases, converting to more common formats like JPEG usually resolves the issue.

Show HN: Helicone (YC W23) – OSS LLM Observability and Development Platform Hey HN, we're Justin and Cole, the founders of Helicone ( https://helicone.ai ). Helicone is an open-source platform that helps teams build better LLM applications through a complete development lifecycle of logging, evaluation, experimentation, and release. You can try our free demo by signing up ( https://ift.tt/hJHnzId ) or self-deploy with our new fully open-source helm chart ( https://ift.tt/rWDKy13 ). When we first launched 22 months ago, we focused on providing visibility into LLM applications. With just a single line of code, teams could trace requests and responses, track token usage, and debug production issues. That simple integration has since processed over 2.1B requests and 2.6T tokens, working with teams ranging from startups to Fortune 500 companies. However, as we scaled and our customers matured, it became clear that logging alone wasn’t enough to manage production-grade applications. Teams like Cursor and V0 have shown what peak AI application performance looks like and it's our goal to help teams achieve that quality. From speaking with users, we realized our platform was missing the necessary tools to create an iterative improvement loop - prompt management, evaluations, and experimentation. Helicone V1: Log → Review → Release (Hope it works) From talking with our users, we noticed a pattern: while many successfully launch their MVP quickly, the teams that achieve peak performance take a systematic approach to improvement. They identify inconsistent behaviors through evaluation, experiment methodically with prompts, and measure the impact of each change. This observation shaped our new workflow: Helicone V2: Log → Evaluate → Experiment → Review → Release It begins with comprehensive logging, capturing the entire context of an LLM application. Not just prompts and responses, but variables, chain steps, embeddings, tool calls, and vector DB interactions ( https://ift.tt/CGz9hVs ). Yet even with detailed traces, probabilistic systems are notoriously hard to debug at scale. So, we released evaluators (either via LLM-as-judge or custom Python evaluators leveraging the CodeSandbox SDK - https://ift.tt/pgYh2yS ). From there, our users were able to more easily monitor performance and investigate what went wrong. Did the embedding search return poor results? Did a tool call fail? Did the prompt mishandle an edge case? But teams would still edit prompts in a playground, run a few test cases, and deploy based on intuition. This lacked the systematic testing we’re used to in traditional software development. That’s why we built experiments (similar to Anthropic's workbench but model-agnostic) ( https://ift.tt/O03AhX8 ). For instance, when a prompt generates occasional rude support responses, you can test prompt variations against historical conversations. Each variant runs through your production evaluators, measuring real improvement before deployment. Once deployed, the cycle begins again. We recognize that Helicone can’t solve all of the problems you might face when building an LLM application, but we hope that we can help you bring a better product to your customers through our new workflow. If you're curious how our infrastructure handled our growth: Our initial architecture struggled - synchronous log processing overwhelmed our database and query times went from milliseconds to minutes. We've completely rebuilt our infrastructure with two key changes: 1) using Kafka to decouple log ingestion from processing, and 2) splitting storage by access pattern across S3, Kafka, and ClickHouse. This was a long journey but resulted in zero data loss and fast query times even at billions of records. You can read about that here: https://ift.tt/lq0wzCo... We'd love your feedback and questions - join us in this HN thread or on Discord ( https://ift.tt/7McyUL3 ).

Last summer I was struggling to get my Figma designs shipped - stuck waiting for dev bandwidth and trying to hand off every iteration. Got really frustrated and decided to do something about it. Today we're launching a native integration between Builder.io and Lovable that lets designers directly convert Figma designs into production-ready apps. No code, no BS, just a working app you can iterate on. How it works: - Design in Figma (supports Auto-Layout) - Export through Builder.io's plugin (2 modes: quick or pixel-perfect) - Opens in Lovable where you can add functionality via prompts - Connect Supabase for backend/auth/db if needed - One click deploy to cloudflare We've been testing this with early users and seeing designers ship entire apps solo in hours instead of weeks.

Show HN: Crawlspace – A centralized web crawling platform built on Cloudflare Crawlspace is a centralized web crawling platform that benefits crawler developers AND website owners. Developers can affordably crawl tens of millions of pages per month, scrape with LLMs, and save data in attached storage. Website owners are shielded by a platform-wide TTL cache that absorbs redundant bot traffic. AI bots are running rampant on the open web. Many recent HN stories[1][2][3][4] describe how web crawlers have run amok and hammer websites with DDoS-like traffic. They often do this with blatant disregard of website owners' wishes (e.g. ignoring robots.txt, 429s, Retry-After headers, etc) because they face no repercussions for deploying poorly-behaved crawlers (and are not incentivized to improve them). The knee-jerk reaction to fix this problem is to give more tools to website owners. Maintaining denylists of IP addresses and user agents, implementing honeypots and tarpits, etc are tactics that website owners use to combat the problem. However, this ends up resulting in and endless arms race between web crawlers and website owners, as they each try to employ new mechanisms of one-upping each other. Crawlspace takes a different approach _by providing a convenient and affordable platform to web crawler developers_. By funneling web crawling traffic through a centralized platform, we can control neat things like making crawlers well-behaved by default, implementing proper caching, and more — all the tedium that that developers don't want to (and therefore, don't) do themselves. Music streaming services like Spotify used convenience and affordability to curb music piracy; we're following the same playbook to curb rampant bot traffic on the internet. In about 50 lines of code, you can deploy a performant and polite web crawler on Cloudflare's network. Every crawler gets its own queue, SQLite database, vector database, and S3-compatible bucket, which allows you to query your crawl as it's crawling with either SQL statements or a RAG chat interface. We've stitched together 10+ Cloudflare products including Queues, Durable Objects, Browser Rendering, Workers AI, D1, R2, and Vectorize. Please let us know what you think!

Show HN: Searchlight – Open-source Postgres client for macOS Hi HN, Over the past year, I’ve been building a native MacOS Postgres client for my personal use. While there are plenty of existing clients, I built this because: - No open-source Postgres client matched the smooth UX of tools like Sequel Pro/SequelAce (for MySQL). - I missed the satisfaction of long-term product ownership and iteration—recent work has me jumping between projects. - I’ve been using Postgres more lately and wanted to get hands-on to deepen my knowledge. I also wanted a playground to experiment with client features that would help me on day-to-day. Some I have implemented already: - Hover over a foreign key column to see the linked record in a popover. - Autocomplete lookup for foreign key records when inserting/editing rows. - High-level stats pop-up when hovering over a column. - Contextual “sugar” features (e.g., UUID fields include a button to generate a UUID while editing). - On update/insert failures, it tries to highlight the issue on the problematic column, vs some generic error alert. It’s still very bare-bones and I still use it alongside other tools for features I haven’t implemented (management features for tables/schemas/user), but I’m already using as my main client for 90% of what I work on. I’m sharing here to get early feedback. Mostly trying to determine if more people find value in this project if I keep developing it. ps.: I’m using my personal Apple developer account so I can’t notarize the app with Apple. If you try to install from the GitHub releases page MacOS will warn that it can’t verify the developer identity, so you will need to approve the install on Settings > Privacy, or build from source. https://ift.tt/E6rJHYO January 20, 2025 at 09:50PM

Show HN: Compile C to Not Gates Hi! I've been working on the flipjump project, a programming language with 1 opcode: flip (invert) a bit, then jump (unconditionally). So a bit-flip followed by more bit-flips. It's effectively a bunch of NOT gates. This language, as poor as it sounds, is RICH. Today I completed my compiler from C to FlipJump. It takes C files, and compiles them into flipjump. I finished testing it all today, and it works! My key interest in this project is to stretch what we know of computing and to prove that anything can be done even with minimal power. I appreciate you reading my announcement, and be happy to answer questions.

Show HN: News Minimalist – News ranked by significance Hey HN! I'm the author of News Minimalist — a news aggregator where all news is ranked by significance on a scale from 0 to 10. The project was born out of personal pain — I wanted a way to read only significant news, like major humanity milestones, or historical political events, filtering out all the celebrity gossip and smartphone releases. But I couldn't find a way to do that — everywhere I looked, the news was ranked by popularity, coverage, or relevance, not significance. I first tried to solve the problem in the beginning of 2023 with GPT-3 (the top model at that time) by asking it to estimate the significance of some news stories. The results were painfully bad — for some reason, the model preferred tragic, personal stories, completely missing the essence of what makes the news significant. No amount of prompt engineering could fix that. But it all changed in March 2023 when GPT-4 came out. The scores it gave made much more sense. After a month of work, the first version was ready. News Minimalist had its first successful Hacker News post ( https://ift.tt/MVeb7gc ), and I realized that a lot of people had the same problem I had. I've been working on improving the project ever since. As probably most tech founders, I spent too much time on technical improvements, completely ignoring marketing. But I think that work paid off, and I'm finally satisfied with the scores it gives. The results are posted on the site: https://ift.tt/SrqUaw5 Let me know what you think!

Show HN: QwQ-32B APIs – o1 like reasoning at 1% the cost Ubicloud is an open source alternative to AWS. Today, we launched our inference APIs, built with open source AI models. QwQ-32B-Preview is one of those models; and it can provide o1-like reasoning at 1% the cost. QwQ is licensed under Apache 2.0 [1] and Ubicloud under AGPL v3. We deploy open models on a cloud stack that can run anywhere. This allows us to offer great price / performance. From an accuracy standpoint, QwQ does well in math and coding domains. For example, in the MMLU-Pro Computer Science LLM Benchmark, the accuracy rankings are as follows. Claude-3.5 Sonnet (82.5), QwQ-32B-Preview (79.1), and GPT 4o 2024-11-20 (73.1). [2] You can start evaluating QwQ (and Llama 3B / 70B) by logging into the Ubicloud console: https://ift.tt/SM5wKvp We also provide an AI chat box for convenience. We price the API endpoints at $0.60 per M tokens, or 100x lower than o1’s output token price. Also, when using open models, your first million tokens each month are free. This way, you can start evaluating these models today. ## OpenAI o1 or QwQ-32B In math and coding benchmarks, QwQ-32B ties with o1 and outperforms Claude 3.5 Sonnet. In our qualitative tests, we found o1 to perform better. For example, we asked both models to “add a pair of parentheses to the incorrect equation: 1 + 2 * 3 + 4 * 5 + 6 * 7 + 8 * 9 = 479, to make the equation true.” [3] QwQ’s answer shows iterative reasoning steps, where the model enumerates over answers using light heuristics. o1’s answer to the same question feels like an iterative deepen-and-test (though not purely depth-first). When we asked the models harder questions, it felt that o1 could understand the question better and employ more complex strategies. [3][4] Finally, we found that o1’s advantage in reasoning compounded with other ones. For example, we asked both models to write example Python programs. Looking at the answers, it became clear that o1 was trained on a larger data set and that it was aware of Python libraries that QwQ-32B didn’t know about. Further, QwQ-32B at times flip flopped between English and Chinese, making it harder for us to understand the model. [3] Now, if we think that o1 has these advantages, why the heck are we doing a Show HN on QwQ-32B (and other open weight models)? Two reasons. First, QwQ is still comparable to o1 and Ubicloud offers it for 100x less. You can employ a dozen QwQ-32Bs, prompt them with different search strategies, use VMs to verify their results, and still come in under what o1 costs. In the short term, combining these classic AI search strategies with AI models feels much more efficient than trying to “teach” an uber AI model. Second, we think open source fosters collaboration and trust -- and that is its superpower that compounds over time. We foresee a future where open source AI not only delivers top-quality results, but also surpasses proprietary models in some areas. If you believe in that future and are looking for someone to partner with on the infrastructure side, please hit us up at info@ubicloud.com! [1] https://ift.tt/0NunErG [2] https://ift.tt/OjfcV5R...

Show HN: wonderful.dev – social platform for programmers Hey HN, I'm Alan Founder of wonderful.dev ( https://wonderful.dev/ ) We're building a community for programmers, with a goal to make it easier to network with other devs and connect with companies you’re interested in. The inspiration for wonderful.dev came from my own experiences job searching in the tech industry. I wanted to create a platform where the focus was on mutual interest and meaningful connections instead of resumes, job applications, and coding challenges. Here's how wonderful.dev works: 1. Profile creation: You link accounts like GitHub and WakaTime, and we pull in key metrics to create your profile. 2. Matching: Instead of applying to job postings, you explore companies and star the ones you like. If they star you back, you can chat with them. 3. Community timeline: Like Bluesky for devs, you share updates, interact with other devs, and build your network. When posting to the timeline, we support a subset of Markdown, detect and tag posts with corresponding programming languages for easier discovery, and support integrations with dev tools when posting. Hover over a username to see the programming languages they use, detected from the integrations they connected. Finally, you control your timeline by filtering instead of an algorithm pushing content onto you. More features: https://ift.tt/DPstLF5 Video intro: https://youtu.be/4RLp4Nbmd_o I'd love to hear your thoughts, feedback, or ideas for what could make wonderful.dev even better. https://wonderful.dev January 6, 2025 at 04:12PM

Show HN: TabPFN v2 – A SOTA foundation model for small tabular data I am excited to announce the release of TabPFN v2, a tabular foundation model that delivers state-of-the-art predictions on small datasets in just 2.8 seconds for classification and 4.8 seconds for regression compared to strong baselines tuned for 4 hours. Published in Nature, this model outperforms traditional methods on datasets with up to 10,000 samples and 500 features. The model is available under an open license: a derivative of the Apache 2 license with a single modification, adding an enhanced attribution requirement inspired by the Llama 3 license: https://ift.tt/WKkpgcA . You can also try it via API: https://ift.tt/b7aE3D4 TabPFN v2 is trained on 130 million synthetic tabular prediction datasets to perform in-context learning and output a predictive distribution for the test data points. Each dataset acts as one meta-datapoint to train the TabPFN weights with SGD. As a foundation model, TabPFN allows for fine-tuning, density estimation and data generation. Compared to TabPFN v1, v2 now natively supports categorical features and missing values. TabPFN v2 performs just as well on datasets with or without these. It also handles outliers and uninformative features naturally, problems that often throw off standard neural nets. TabPFN v2 performs as well with half the data as the next best baseline (CatBoost) with all the data. We also compared TabPFN to the SOTA AutoML system AutoGluon 1.0. Standard TabPFN already outperforms AutoGluon on classification and ties on regression, but ensembling multiple TabPFNs in TabPFN v2 (PHE) is even better. There are some limitations: TabPFN v2 is very fast to train and does not require hyperparameter tuning, but inference is slow. The model is also only designed for datasets up to 10k data points and 500 features. While it may perform well on larger datasets, it hasn't been our focus. We're actively working on removing these limitations and intend to release new versions of TabPFN that can handle larger datasets, have faster inference and perform in additional predictive settings such as time-series and recommender systems. We would love for you to try out TabPFN v2 and give us your feedback! https://ift.tt/dymgRUo January 9, 2025 at 10:08PM

Show HN: Cardstock- Free TCG Proxy Manager for Magic, Yugioh, & Pokemon Trading cards are awesome, but paying $30 for some cardboard isn’t. I’ve upscaled 60,000 cards from the entire catalog of Yugioh, Magic, Pokemon, & a newer game, https://elestrals.com . I've made it easy to build a decklist, download it, and then print at home. Modern inkjet printers got really good when nobody was looking. While it’s clear they’re not real cards, the upscaling makes them look great for casual play (these are not tournament legal). It’s totally free, give it a try! Supplies: https://ift.tt/ZtN52GU Printer Settings: https://ift.tt/khXcue3 Instructions: https://ift.tt/zJtW3d6 Overview: I built Cardstock because I had some scripts to do this lying around, and wanted to explore the new Rails 8 magic. Kamal 2 (kamal-deploy.org/) is a game changer, SQLite in production is fine, and the database backed solid family of gems work like a charm. Compute: I am renting a box on https://hetzner.com located in VA for $15/mo. This box has 8 gigs of ram and 2 vCPU's. This is such a deal compared to compute prices on https://render.com . Kamal 2: This thing is amazing. Kamal gives me everything I could want (easy console access, easy shell access, a way to manage secrets, a way to see my logs, and letsencrypt support for DNS), all without a PaaS tax. The best part is the accessories feature: https://ift.tt/LwOoHIp . I am running my main app with two accessories: Meilisearch( https://meilisearch.com ) and OpenObserve ( https://openobserve.ai ). Instead of paying Algolia to host search infrastructure and sentry to host monitoring infrastructure, I’m hosting my own OSS without any fanfare. Upscaling: To upscale the trading cards (a mandatory part of this build, scans are never high enough DPI). I am using this ( https://ift.tt/hMQ0BRx ) model. For upscaling every card, I've used under a hundred bucks of compute. This model was picked on a whim, but worked well enough that I didn’t compare other models. SQLite: I used SQLite combined with Litestream (litestream.io) for my database. While I considered Postgres, I hesitated due to uncertainties around handling backups on self-hosted infrastructure. This was my first time using SQLite in production, and it was functional but with some minor annoyances. Here’s what I encountered: 1. No Default UUID Primary Key Type I had to set primary keys as strings and assign IDs manually from the application record. It’s an annoying workaround but manageable. 2. No Native Array Columns Because SQLite doesn’t support array columns, I had to use its native JSON column type, which just felt icky. If I were working with something like embeddings, this would be especially annoying, because you couldn’t enforce all the records to have the same number of dimensions. 3. Cryptic Errors At one point, a migration failed silently, leaving a cryptic error in schema.rb. The issue was resolved by rolling back the migration and redoing it, but it was once again, annoying. 4. Litestream Defaults Litestream deletes snapshots after 24 hours by default, which is far too short. When I tried to recover some data, I found it had already been deleted. Adjusting these defaults fixed the problem. Solid Queue/Cache/Cable: The solid family of gems are all backed by the database and were a pleasure to work with. Goal was to prevent needing to reach for redis, so you have one less thing to worry about. You end up with a little more latency, which is a totally reasonable tradeoff. Conclusions: We are moving into a post platform as a service world. Instead of buying a bespoke render.com or heroku, you just buy commodity compute and use Kamal to manage. It's like, pretty much all there, excited to see how this space matures. https://ift.tt/8krjed3 January 8, 2025 at 08:41PM

Show HN: A 100-Line LLM Framework I've seen a lot of comments about how complex frameworks like LangChain can be. Over the holidays, I wanted to see how minimal an LLM framework could get if we stripped away everything non-essential. The result is an LLM framework in just 100 lines of code. These 100 lines capture what I see as the core abstraction of most LLM frameworks: a nested directed graph that breaks down tasks into multiple LLM steps, with branching and recursion to enable agent-like decision-making. From there, you can layer on more advanced features like agents, RAG, task decomposition, and more. I’ve intentionally avoided bundling vendor-specific wrappers (e.g., for OpenAI) into the framework. That kind of lock-in can be brittle and is easy to recreate on the fly—just feed the vendor’s API docs into your favorite LLM to generate a new wrapper. With miniLLMFlow, you only get the fundamentals. It also works nicely with coding assistants like ChatGPT, Claude, and Cursor.ai. Because the code is so minimal, you can quickly share the entire "source code and documentation with an AI assistant, and it can help you build new workflows on the spot. I’m adding more examples (including multi-agent setups) and would love feedback! If there's a feature or use case you’d like to see, please let me know.

Show HN: Lightweight Llama3 Inference Engine – CUDA C Hey, recently I took inspiration from llama.cpp, ollama, and many other similar tools that enable inference of LLMs locally, and I just finished building a Llama inference engine for the 8B model in CUDA C. I recently wanted to explore my newly founded interest in CUDA programming and my passion for machine learning. This project only makes use of the native CUDA runtime api and cuda_fp16. The inference takes place in fp16, so it requires around 17-18GB of VRAM (~16GB for model params and some more for intermediary caches). It doesn’t use cuBLAS or any similar libraries since I wanted to be exposed to the least amount of abstraction. Hence, it isn’t as optimized as a cuBLAS implementation or other inference engines like the ones that inspired the project. ## *A brief overview of the implementation* I used CUDA C. It reads a .safetensor file of the model that you can pull from HuggingFace. The actual kernels are fairly straightforward for normalizations, skip connections, RoPE, and activation functions (SiLU). For GEMM, I got as far as implementing tiled matrix multiplication with vectorized retrieval for each thread. The GEMM kernel is also written in such a way that the second matrix is not required to be pre-transposed while still achieving coalesced memory access to HBM. Feel free to have a look at the project repo and try it out if you’re interested. If you like what you see, feel free to star the repo too! I highly appreciate any feedback, good or constructive. https://ift.tt/VJ91tXI January 5, 2025 at 03:37AM

It's amazing how much difference 20 years makes: the hardware is so much more powerful, the web as a deployment platform is so much easier than side-loading onto a PDA through a serial cable or sharing .exe files through e-mail, and my experience as a professional developer makes almost everything so much easier... but at the same, it didn't feel that the language, editor or debugger (TypeScript on Visual Studio Code) were significantly better than good old Visual C++ 6. Repository with the code of the remake: https://ift.tt/Km38pDs (sadly, I cannot provide the video and audio assets themselves under any open license). https://ift.tt/CxmJYuP December 31, 2024 at 04:25PM

Show HN: NeatShift – A Modern Windows File Organizer with Symbolic Link Support Hi HN, I've been developing NeatShift, a Windows application designed to help users organize their files and folders seamlessly using symbolic links. The aim is to declutter storage without disrupting file accessibility. Key Features: Smart Moving: Relocate files while NeatShift creates symbolic links to maintain system functionality. Safety Measures: Options for quick backups with NeatSaves and system restore points to ensure data integrity. Integrated File Explorer: Modern interface with drag-and-drop support, customizable views, and both light and dark themes. Link Management: Easily view and manage all symbolic links in one place. I initiated this project to address the challenges of managing large files on limited SSD storage, ensuring that moving files doesn't break application dependencies. NeatShift is open-source (GPL-3.0 license), and I'm actively seeking feedback and contributors to enhance its functionality. Explore the project here: GitHub Repo https://ift.tt/IKORPoc Looking forward to your thoughts and suggestions! https://ift.tt/IKORPoc January 3, 2025 at 12:56AM

Show HN: I built a green noise player to help you relax, focus, and stay calm Sometimes, I struggle to block distractions and create a calming environment while working. Most tools I’ve tried were either cluttered, didn’t provide the right kind of sound, or required payment. So, I decided to build my own simple green noise player. For context, green noise features balanced, mid-range frequencies that mimic soothing natural sounds—ideal for relaxation, focus, or creating a peaceful backdrop while working. It’s also great for taking a mindful break during a busy day. Right now, it’s a free, lightweight, browser-based solution. Playback pauses on mobile when the screen locks, but I’m exploring ways to improve it. Maybe a dedicated mobile version in the future?

Show HN: Cave Adventure 1976 PICO-8 port Made this during COVID. I was into PICO-8 at the time and saw someone ported DOOM to it. I'm more of a text adventure guy, so I decided to port ADVENT. Basically I wrote a FORTRAN-to-Lua transpiler. The hardest part was figuring out what version of FORTRAN the source code was written in, finding a manual, cramming it into the limited cartridge space, but most of all, wrapping my mind around the data file format. Always admired Will Crowther for making this. Very fun project. I recorded myself during the whole process but I never posted a video.

Show HN: Jido – Run 10k agents at 25KB each (Elixir) Hi HN! I'm Mike Hostetler and I built Jido, an Agent SDK in Elixir that lets you run thousands of agents without heavy infrastructure. Repo: https://ift.tt/CO4Wr7x Getting Started: https://ift.tt/NHdtQnI Why another framework? After using several popular Agent frameworks and platforms, I had two key challenges: - Running multiple agents required process-heavy infrastructure like Docker or K8s. Running 50,000 agents in parallel was costly and diminished the benefits of agentic programming. - Today's agents require too much human intervention when building workflows. Why couldn't agents manage their own WDLC (Workflow Design Life Cycle)? This felt like a major missing piece. Agentic frameworks were written for humans. LLMs working with this code were constantly working around human work-style assumptions. So, I wrote a framework specifically for LLMs to code and operate their own agentic flows. Elixir was a natural choice because of it's functional nature, rock-solid concurrency primitives and "let-it-crash" philosophy with dynamic error compensation. Hot code reloading was a bonus. Agents in Jido use 25Kb of memory at rest and can easily serialize then hibernate for long-lived access. Agents possess the APIs to dynamically start and manage their own sub-agents or any other Elixir process utilizing Elixir's OTP architecture. Jido Actions are functional primitives that Agents can dynamically orchestrate into workflows. Generated code can either run in a separate process in the current VM or in another BEAM VM that's linked and hardened before introduction into the Agent VM. I'm excited to help enable a world where thousands of agents work seamlessly on behalf of their human operators. Thanks! https://ift.tt/CO4Wr7x December 30, 2024 at 09:58PM

Show HN: Skybear.net – A managed platform automating Synthetic HTTP API testing Hey folks, I am finally posting a Show HN post for a project I have been working on for several months now, and it's in a state where I already get a lot of value myself, so I am happy to share broadly. The pitch line is: "Skybear.NET is a managed platform automating Synthetic HTTP API testing." At the moment, the main source file format supported for your API tests are Hurl.dev files [1]. Hurl is a CLI tool wrapping `curl` and it's really awesome. At least check that out :) I am not affiliated directly with the Hurl CLI tool, and the platform I am building provides full Hurl compatibility. I have been using Hurl for a few years now [2], and use it for my API testing, for orchestrating a bunch of HTTP APIs, and in general whenever I need to do anything with HTTP requests, I reach for Hurl. You can try without signup the basic execution feature with the free Open Editor [3], but for full functionality (retaining responses and cron triggers) you need a signed in account, even free. The Skybear.NET platform: 1. Has Hurl Compatibility, so take your local scripts and run them on the cloud as well. No changes needed. 2. Provides managed infrastructure for authoring, storing, and most importantly executing your Hurl scripts, that automatically scales to handle as many script runs as you need. 3. Generates detailed reports from your tests execution, automatically persisting requests and response bodies for introspection in the future, and with automatic insights coming up soon. 4. Supports multiple ways of triggering execution of your scripts, including periodic executions, and on-demand HTTP triggers enabling integration with your CICD pipelines. Most importantly, it eliminates excessive per-request/per-step/per-check charges, leading to substantial cost-savings for complex multi-step API tests covering complete user-journeys. I consider a "script project run" to be the main unit in my pricing, which includes execution of all the source files of the script project, which can be tens or hundreds of requests. I am starting to document some of the architecture of the platform as well [4], but in a nutshell, all your data is encrypted inside the application before stored on AWS (S3, DynamoDB, also encrypting at rest) [5], the control plane runs on Hetzner and AWS EC2, and the execution servers running your scripts run on Fly and soon on AWS EC2 (for some plans). Future plans depend a lot on feedback from users. I already have a long list of things I personally want to have, but as more users start using I would like to see user needs influencing the roadmap more. Some upcoming features: 1. Insights and metric graphs for historical tracking of your tests (per project, per file, per request URL). 2. Automatic generation of tests based on OpenAPI schemas, HAR files, etc. 3. Export API of all the data and reports for your own consumption. 4. OTEL traces generated per script run, exportable and sent to APM products. Thank you, and I hope you find it interesting too!

Show HN: Convert ePUB to Audio Files A way to generate .mp3 files from ePUB. I wanted to continue "reading" even after my eyes got tired or if I went away from the screen. For these cases, what I did was select a given text, and select "Speech". If you've used this before, you know it's fine for small sections, but not for big chunks of text. So, I challenged myself to create a project that would "text-to-speech" a given book. After some attempts, I came up with a good-enough initial version using Golang. It will parse an ePUB into sections and run MacOS's `say` command to generate audio files. For now it's quite basic, but worked fine for the few files I tested. https://ift.tt/MjHxpFb December 22, 2024 at 10:45PM
Show HN: Get e-signatures & pay per signed doc Woke up today with a 100-degree fever & found out Google is now our competitor. Last week, we started building signwith.co/ - a simple, pay-per-use e-signature tool for people who are struggling with complex e-sign tools. The plan was to build quietly, run a private beta, get 50 users in 15 days, and then do a launch. Easy peasy. But since Google dropped into the e-signature space - we needed to talk. So after 30 minutes of existential dread, a lot of “what are we even doing?” thoughts, and one strong dose of paracetamol we said, screw it. - let’s change gears. So now we're opening our beta, and here's the deal: • All the people who join will get free credits worth 10 signed docs • 12 months credit validity • No complexity • No hidden cost • No subscription commitment You can join the beta here - http://signwith.co That said, we see Google's entry in the signature space as validation. This event expanded the market with such massive awareness. Let me be clear: We’re not trying to be DocuSign, Google, or any other enterprise beast. We’re indie makers and building for: • The freelancers • The consultants • The indie and small business owners • and anyone who just needs a contract signed—fast, simple, no headaches. Here’s how SignWith works: • Upload your doc • Drop signature spots • Send it out and track • Pay per signed document That’s it. No subscriptions. No feature bloat. No crazy hidden charges and no complex pricing tiers. If you've read it so far, would love to see you on the other side. And hey, if you’ve got any feedback, suggestions, or just want to tell us what you need, reply here or drop me a DM. We’re all ears! Cheers! https://signwith.co/ December 20, 2024 at 05:03PM
Show HN: Rivet Actors – Durable Objects build with Rust, FoundationDB, Isolates Hello! We posted a Show HN for Rivet last year for our container orchestration project ( https://ift.tt/8xJM1La ). In that time, a lot has changed that I think HN will find interesting. Rivet is open-source actor infrastructure similar to Cloudflare's Durable Objects. Rivet itself already serves millions of MAU in production using our current container runtime – primarily for multiplayer games – and Rivet Actors are a new extension to support actor-like workloads. Rivet Actor's core primitives are RPC, state, and events. Actors are powered by Rust, V8 isolates (supports Deno), and FoundationDB. An architecture diagram is available here for [1]. If you're not familiar with FoundationDB, you're overdue to watch Dave Rosenthal's talk [3]. (I firmly believe it's by far the best permissively licensed database; if only it had a well maintained SQL layer.) Here's where Rivet's architecture gets fun – we don't rely on a traditional orchestrator like Kubernetes or Nomad for our runtime. Instead, our orchestrator is powered by an in-house actor-like workflow engine – similar to how FoundationDB is powered by their own actor library (Flow [4]) internally. It lets us reliably & efficiently build complex logic – like our orchestrator – that would normally be incredibly difficult to build correctly. For example, here's the logic that powers Rivet Actors themselves with complex mechanisms like retry upgrades, retry backoffs, and draining [2]. One of the reasons we built Rivet Actors is because we tried to replace most of our Redis-based realtime infrastructure with Durable Objects. The architecture allowed us to build realtime features much faster & efficiently, but the platform & APIs were needlessly rigid and difficult to use. Our goal is to build an actor-like platform that includes the bells and whistles required for developers to benefit from the actor model without the learning curve of tools like Erlang/OTP, Akka, or Orleans. Rivet Actors provides a few key benefits in flexibility over Durable Objects: - Open-source (Apache 2.0) – built to be self-hosted and deployed on-prem - Provides observability out of the box, no Logpush required - Rivet Actors support the Deno runtime, so NPM & JSR just works - @rivet-gg/actor [5] framework provides RPC, state, and events out of the box for faster bootstrapping; you can modify and deploy it yourself - Supports both V8 isolates & Docker-compatible containers so you can run any software you'd like, like Godot/Unity servers or video transcoding - Also supports TCP & UDP (we run games!) - Provides vanilla HTTP API for easy use with existing apps - Full control over regions There's plenty more that I don't have space to talk about.

Show HN: openai-realtime-embedded-SDK Build AI assistants on microcontrollers Hi HN! This is an SDK for ESP32s (microcontrollers) that runs against OpenAI's new WebRTC service [0] My hope is that people can easily add AI to lots of 'real' devices. Wearable devices, speakers around the house, toys etc... You don't have to write any code, just buy a device and set some env variables. If you have any feedback/questions I would love to hear! I hope this kicks off a generation of new interesting devices. If you aren't familiar with WebRTC it can do some magical things. Check out WebRTC for the Curious[1] and would love to talk about all the cool things that does also.

Show HN: CxReports – Low-Code Tool for User-Facing PDF Reports Marko here from Codaxy. For over two years, we have been working on CxReports, a low-code tool for creating user-facing PDF documents and reports. We first saw the problem in wealth management, where reports are crucial for the user experience. Software vendors have customers who ask for customized reports with unique content, branding, and visuals. The solution was to build a tool that allows customization for each customer, which even customers themselves can use. Over time, this evolved to be a generic solution that works for various other use cases. CxReports lets you build reports visually. You can connect to a database and get data using SQL queries. It supports scheduled report generation and delivery. The API enables accessing CxReports from other applications or workflows. https://cx-reports.com/ You can easily try it out with our Docker image - https://ift.tt/mCSAGK3 . We offer a free tier for registered users. How do you currently handle customized reporting? Are there specific challenges you face with generating user-facing reports? I’d love to hear your thoughts and feedback. Looking forward to the discussion! December 19, 2024 at 08:45PM
Show HN: CCState is a semantic, strict, and flexible state management library CCState is a semantic, strict, and flexible state management library suitable for medium to large single-page applications with complex state management needs. The name of CCState comes from three basic data types: computed, command, and state. https://ift.tt/69E3VWp December 19, 2024 at 03:44PM
Show HN: I spent 4 years bootstrapping a financial planning tool to 30k MAUs Hey everyone! I'm back with an update on this post [0]. Last year, I quit my corporate job and went full-time on ProjectionLab, the long-term financial planning app I've been building for the past 4 years, which some of you may recognize. The decision to go all-in felt like a huge leap. But it was the right call, and it's been a good year. And without the HN community, it would not have happened. As I mentioned last time [0], the feedback on my original Show HN is THE reason I'm still here working on this. I'm really grateful for that. And I hope the way I’ve grown PL -- staying bootstrapped and focused on users -- resonates with the early supporters who helped to shape it. For now I'm still the only engineer, burning the candle at both ends, but luckily I'm not feeling burnt out myself! It's been a fun and memorable year: - 6,139 commits, 221,484 insertions, 116,255 deletions - Shared my story on the ChooseFI podcast [1] (one of the original sources of inspiration for this project) - Started building a team (2 team members for customer success, 1 leading growth & marketing) - Doubled our customer base - Took no external funding, keeping our interests as aligned with users as possible Okay, but what did I actually do since last time? [2] Here's a quick cross-section: - Compare mode upgrades to explore what-if scenarios overlaid on the same chart with visual deltas/diffs - Launched ProjectionLab for Employers [3]: offer PL as a benefit, or get your employer to pick up the tab - Major tech stack migrations: Vue 2 -> Vue 3, Vue CLI -> Vite, Vuetify 2 -> Vuetify 3, Vuex -> Pinia, Jest -> Vitest, Firebase Namespaced API -> Modular API, Vike + SSG for marketing site - Advanced visualization features (1-click-plot any metric, interactive event icons in charts, etc) - Improved tax estimation & tax analytics - Simultaneous editing on multiple devices - MFA support - Rebuilt the help center, added more educational content and YouTube tutorial videos - Made it possible to book a 1-on-1 session for educational/training purposes - Converted ~65% of the codebase from JavaScript to TypeScript - And more! [2] I never saw myself as an entrepreneur/founder type. But apparently I've now spent 4 years turning a side project into a real business. I couldn't have done it without the initial support from this community, and I'd love to hear what you think of the updates and where you'd like to see things go from here. --Kyle [0] https://ift.tt/EzIfvCd [1] https://ift.tt/AH0Y5Um...

Show HN: Stringify.org – encode any text as a JavaScript string Do you ever want to embed a super long string in JavaScript, and find yourself escaping quotes or interpolations by hand? I find this comes up a lot, particularly when you're doing code generation stuff, because you need to have examples of code for the LLM, and that code often has strings embedded inside it. For example, take a look at the code properties in this JSON array[1]. Introducing stringify.org, the world's only correct-by-definition JavaScript string encoder website. It uses JSON.stringify, which is the only guaranteed method to output a string that is also valid JavaScript. It's in the spec.

Adventures in OCR Hello HN! In a recent "Ask HN: What are you working on?" thread, I mentioned I was working on OCRing a large book: https://ift.tt/5Y6N4HU The post generated some interest so I thought I would keep HN posted. The book is Saint-Simon’s Memoirs -- an invaluable historical account of the French court under Louis XIV, full of wit, sharp observations, and of incredible literary value. I'm OCRing the edition of reference made between 1879-1930, that contains a lot of comments and footnotes: 45 volumes, ~27,000 pages. Here's a link to a blog post that describes the techniques used so far (the project is still ongoing): https://ift.tt/xOoH4Jg But you may also directly access the result here: https://ift.tt/vqfNZYC This web app (not optimized for mobile, sorry) solves a tricky problem of preloading images efficiently. In short: preloading the next image isn't enough, since browsers will repaint if an image is moved, or scaled. Or browsers won't paint at all if visibility is hidden or opacity is zero, and will paint only when those values change. On an average, slow machine, this takes visible time. But if an image is simply behind another element, it will be painted, and the removal of the covering element or changing the z-index will not trigger a repaint. (Preloading is important because it lets one review results fast; if one has to wait 150-200 ms between images it's simply discouraging). Would love to hear feedback; happy to answer any question! https://ift.tt/xOoH4Jg December 17, 2024 at 10:30PM
