Show HN: Cave Adventure 1976 PICO-8 port https://ift.tt/JGa1Eo3

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. Future work maybe. https://ift.tt/DURsZ7r December 31, 2024 at 09:14PM

Show HN: Handwritten Christmas Card for Hacker News https://ift.tt/8wMZWNc

Show HN: Handwritten Christmas Card for Hacker News Hi HN, I’ve been working on a small project that transforms handwritten notes into animated, shareable cards. While the create functionality isn’t live yet, I wanted to share a sneak peek by creating a handwritten Christmas card specifically for the HN community. I started thinking about this after seeing too many AI-generated cards, cookie-cutter email templates, and overly polished designs that lack any personal touch. A friend recently sent me a handwritten card in the mail, and I found it nice that he took his time to write a handwritten note. I wanted to capture that same feeling without the overhead of snail mail. https://ift.tt/Me8T0pP December 28, 2024 at 03:06PM

Show HN: Jido – Run 10k agents at 25KB each (Elixir) https://ift.tt/F4oH5gq

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/CG94Ab2 Getting Started: https://ift.tt/JbnkfN1 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/CG94Ab2 December 30, 2024 at 09:58PM

Show HN: A search engine that values depth over popularity Hey HN, I'm excited to introduce Graphthem, a search engine designed to explore the deeper layers of knowledge rather than just surface-level popularity. While many AI search engines simply summarize top N results, we've found this approach often misses the many good stuff that is buried deeper in the links and references. Graphthem takes a different approach. we don't just look at the first few pages we find. We also dig into what those pages link to, so you get the whole story. This allows us to deliver answers that capture not just what's immediately visible, but also the foundational ideas and deeper insights that inform those results. Here's a comparison between Perplexity and Graphthem: Query 1: "most watched youtube videos?" Perplexity: https://ift.tt/FvVwLfA... Graphthem: https://ift.tt/qJHjcGr... - Query 2: "what is pagerank?"

Show HN: Sine Wave Speech, a real-time audio effect in Rust->WASM Source code: https://ift.tt/1wWDFxc An interactive website for exploring how human speech can be reduced to just a few sine waves and still be intelligible - or at least recognized to be a human voice. On top of that, I've added various ways to make the sound more musical. The sound effect is based on research from the 80s, which has largely been forgotten by then. To have the effect run in real-time in the browser, I opted to use Rust compiled into WebAssembly. Still, I had to rewrite some linear algebra routines.

Show HN: Otto-m8 – A low code AI/ML API deployment Platform https://ift.tt/jA0OaSi

Show HN: Otto-m8 – A low code AI/ML API deployment Platform Hi all, so I've been working on this low to no code platform that allows you to spin up deep learning workloads(I'm talking LLM's, Huggingface models, etc), interconnect a bunch of them, and deploy them as API's. The idea essentially came up early in September, when experimenting with combining a Huggingface based BERT model with an LLM at work, and I realized it would be cool if I could do that instantly(especially since it was a prototype). At the time, I was considering a platform that could essentially help you train deep learning models without any code. It was my observation that much of the code required to train or even run inference on HF models have matured significantly. But before I solved that problem, I wanted to solve inference. Initially inspired by n8n and AWS Cloudformation, I built out otto-m8 (translates to automate). Given a json payload that lists out all the resources, and how each model is interconnected, launch it as one-off API the user can query. And thanks to Reactflow, the UI was just something I couldn't just not implement. And as I built it out, I did not want to miss out on the LLM and Agent bit. With otto-m8, today, you can launch complex workflows by interconnecting HF models and LLM's(currently it supports OpenAI and Ollama only). But I like to see it being more than that. At the core, every workflow is an input process output model. Inputs get processed and there's an output. Therefore, with the way things are setup, one can integrate almost anything and make it interconnectable. Project Link: https://ift.tt/A13yqQ0 Let me know what you guys think. I really would love feedback! https://ift.tt/A13yqQ0 December 22, 2024 at 03:09AM

I see a lot of stuff online about the death of software engineers and wanted to challenge myself to see if I could create something myself.

It's super basic but felt good to make something myself and I learned a lot.

Show HN: Skybear.net – A managed platform automating Synthetic HTTP API testing https://ift.tt/pqvT2dU

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: Get e-signatures & pay per signed doc https://ift.tt/VBz84Tg

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 https://ift.tt/26QCJx3

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. 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. Give our docs a read if you'd like to learn more [6] or read about internal design decisions [7]. I'll be in the comments answering questions!

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/lt4HNMT . 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: Mizu.js – Lightweight HTML templating library for any-side rendering https://ift.tt/4NtoECF

Show HN: Mizu.js – Lightweight HTML templating library for any-side rendering Hey HN, I'd like to share a fun project I've been working on: mizu.js. It's a js library that add functional attributes support into your html, designed to be a simple and flexible alternative to fully-fledged web frameworks (such as Vue, React, and Angular), while offering more capabilities than other lightweight options (like Alpine.js and htmx). As it's written using modern ES features and due to its isomorphic nature, it can be run in both browsers and runtimes (Node, Deno, Bun) without any changes. This makes it ideal for client-side and server-side rendering, as well as static site generation, whichever environment you prefer. Just include the script in any web page (or backend) to get started. You can template content, bind attributes, add interactivity, handle HTTP interactions, create custom components, and much more — all out of the box, without any configuration, transpilation steps, or builds. I hope you'll find mizu.js as exciting and useful as I do and I'd love to get your feedback! You can learn more about it at https://mizu.sh ! Online playground: https://ift.tt/AOZszSF Custom builder: https://mizu.sh/build Code coverage: https://ift.tt/hL12VBa GitHub: https://ift.tt/Bg28cux ## Motivation ## Nowadays, setting up a complete environment and installing thousands of packages is often required just to create a simple "Hello World" page. Yet, with the current ECMAScript standard, vanilla JS has never been more powerful. It offers built-in custom HTML components, proxies for changes tracking, weak references for better memory management, and many new data structures and methods. So why is web development still insanely complex? mizu.js aims to avoid adding bloat on top of native features, and instead focus on providing convenience helpers. It's basically "glue" around all these native features with added sugar, a recipe for a lightweight yet powerful utility. All evaluated expressions are interpreted as vanilla JavaScript, and you add your instructions directly into your HTML. So if you know already know about JS/HTML, then you're already 80% know of how to use mizu.js (add an extra 10% if you've used Vue, Alpine.js or htmx in the past as some syntax and concepts are inspired by it), the rest is basically just remembering the directive names. The learning curve is that small. Also, you may have heard of https://matcha.mizu.sh , a CSS stylesheet to instantly make your web page stylized. Well, it's a great companion to mizu.js. With both of them, you can create MVPs for your projects super fast! https://mizu.sh December 19, 2024 at 11:55PM

Show HN: Musoq – Query Anything with SQL Syntax (Git, C#, CSV, Can DBC) https://ift.tt/1vC7oiQ

Show HN: Musoq – Query Anything with SQL Syntax (Git, C#, CSV, Can DBC) Hey, For those of you who don't know my little tool Musoq, I wanted to introduce it as a small tool that allows you to query with SQL-like syntax without any database. It allows you to query various things from niche ones like CAN DBC files, weird ones like C# code, interesting ones with Git querying to regular stuff like CSV, TSV and various others. I am quite a bit experimenting with various things so I'm hybridizing the engine with LLMs or doing other weird stuff that are more or less practical :-) I wanted also to share some recent developments in this little project as I hope it might be interesting to some of you. New Experimental Plugins: * Git Plugin (Beta) : I've been working on Git repository querying - managed to test it on the EF Core repo (16k commits) and it seems to work okay * Roslyn Plugin (Beta) : Added basic C# code analysis capabilities For the very first time: I've extended CROSS APPLY to use computed results as arguments! Now the operator can use values from the current row as inputs. Here's an example: SELECT f.DirectoryName, f.FileName FROM #os.directories('/some/path', false) d CROSS APPLY #os.files(d.FullName, true) f WHERE d.Name IN ('Folder1', 'Folder2') After another pack of fixes I'm finally able to query multiple git repositories AT ONCE! with ProjectsToAnalyze as ( select dir2.FullName as FullName from #os.directories('D:\repos', false) dir1 cross apply #os.directories(dir1.FullName, false) dir2 where dir2.Name = '.git' ) select c.Message, c.Author, c.CommittedWhen from ProjectsToAnalyze p cross apply #git.repository(p.FullName) r cross apply r.Commits c where c.AuthorEmail = 'my-email@email.ok' order by c.CommittedWhen desc Under the Hood: - Added a Buckets feature for memory management (currently just testing it with the Roslyn plugin) - Moved to .NET 8 - Added CROSS/OUTER APPLY operators - Made some improvements to error messages and runtime behavior New piping features: I've been experimenting with piping capabilities: * Image Analysis with LLMs : ./Musoq.exe image encode "image.jpg" | ./Musoq.exe run query "select s.Shop, s.ProductName, s.Price from ..." * Text Data Extraction : Get-Content "ticket.txt" | ./Musoq.exe run query "select t.TicketNumber, t.CustomerName ... from #stdin.text('Ollama', 'llama3.1') t" * Data Source Combination : { docker image ls; ./Musoq.exe separator; docker container ls } | ./Musoq.exe run query "..." I'm working on comprehensive documentation: I encourage you especially to look at section "Practical Examples and Applications" and "Data Sources" where you can look at all the tables the tool currently provides. < https://puchaczov.github.io/Musoq/ > Other Changes: - Made some improvements to OS and Archive data sources (OS can now query metadata like EXIF) - Added a few fields to CAN DBC plugin - Command outputs can now be used as inputs for queries I'm hoping to: - Improve stability and add more tests - Flesh out the documentation - Work on package distribution (Scoop, Ubuntu packages) - Share some examples of source code querying with Roslyn Ideas for later: - WHERE robust analysis and optimizations - DISTINCT operator implementation - PROTOBUF schema support - Performance improvements - Query parallelization - Recursive CTEs - Subqueries I'd really appreciate any thoughts or feedback!

Show HN: Bodo – high-performance compute engine for Python data processing https://ift.tt/81kUoWq

Show HN: Bodo – high-performance compute engine for Python data processing Hello HN, I’m excited to share Bodo, an open-source compute engine designed for large-scale data processing in native Python. Bodo is powered by an auto-parallelizing JIT compiler and an HPC backend, enabling it to generate highly optimized, parallel binaries (MPI) for Pandas and NumPy code—all without requiring any code rewrites. Our latest benchmark demonstrates 20x to 240x speedup over traditional distributed computing frameworks like Spark, Ray, and Dask (code and details in repo). The inspiration for Bodo came from my background in HPC, when I saw how extremely slow and hard to use Spark was (has gotten better over the years but still not great). Of course, a compiler has its own limitations (e.g. not all Python is compilable), but I think it’s leaps and bounds better. Let me know what you think. https://ift.tt/BCaHAXL December 18, 2024 at 11:10PM

Show HN: I spent 4 years bootstrapping a financial planning tool to 30k MAUs https://ift.tt/licJ6p8

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/QlxAqmW [1] https://ift.tt/GpmzE7O...

Show HN: Adventures in OCR https://ift.tt/RHYa7D9

Show HN: 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/xvsrmY1 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/ZFQ1gYP But you may also directly access the result here: https://ift.tt/QCLB2ny 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/ZFQ1gYP December 17, 2024 at 10:30PM

Show HN: I built an open-source data pipeline tool in Go https://ift.tt/u6bJBgH

Show HN: I built an open-source data pipeline tool in Go Every data pipeline job I had to tackle required quite a few components to set up: - One tool to ingest data - Another one to transform it - If you wanted to run Python, set up an orchestrator - If you need to check the data, a data quality tool Let alone this being hard to set up and taking time, it is also pretty high-maintenance. I had to do a lot of infra work, and while this being billable hours for me I didn’t enjoy the work at all. For some parts of it, there were nice solutions like dbt, but in the end for an end-to-end workflow, it didn’t work. That’s why I decided to build an end-to-end solution that could take care of data ingestion, transformation, and Python stuff. Initially, it was just for our own usage, but in the end, we thought this could be a useful tool for everyone. In its core, Bruin is a data framework that consists of a CLI application written in Golang, and a VS Code extension that supports it with a local UI. Bruin supports quite a few stuff: - Data ingestion using ingestr ( https://ift.tt/Igu8UlM ) - Data transformation in SQL & Python, similar to dbt - Python env management using uv - Built-in data quality checks - Secrets management - Query validation & SQL parsing - Built-in templates for common scenarios, e.g. Shopify, Notion, Gorgias, BigQuery, etc This means that you can write end-to-end pipelines within the same framework and get it running with a single command. You can run it on your own computer, on GitHub Actions, or in an EC2 instance somewhere. Using the templates, you can also have ready-to-go pipelines with modeled data for your data warehouse in seconds. It includes an open-source VS Code extension as well, which allows working with the data pipelines locally, in a more visual way. The resulting changes are all in code, which means everything is version-controlled regardless, it just adds a nice layer. Bruin can run SQL, Python, and data ingestion workflows, as well as quality checks. For Python stuff, we use the awesome (and it really is awesome!) uv under the hood, install dependencies in an isolated environment, and install and manage the Python versions locally, all in a cross-platform way. Then in order to manage data uploads to the data warehouse, it uses dlt under the hood to upload the data to the destination. It also uses Arrow’s memory-mapped files to easily access the data between the processes before uploading them to the destination. We went with Golang because of its speed and strong concurrency primitives, but more importantly, I knew Go better than the other languages available to me and I enjoy writing Go, so there’s also that. We had a small pool of beta testers for quite some time and I am really excited to launch Bruin CLI to the rest of the world and get feedback from you all. I know it is not often to build data tooling in Go but I believe we found ourselves in a nice spot in terms of features, speed, and stability. https://ift.tt/AxHMSiF I’d love to hear your feedback and learn more about how we can make data pipelines easier and better to work with, looking forward to your thoughts! Best, Burak https://ift.tt/AxHMSiF December 17, 2024 at 10:10PM

Show HN: I made a multiplayer crossword game https://ift.tt/Tw5rl43

Show HN: I made a multiplayer crossword game Hey HN, I’ve been working on this multiplayer crossword for a while now. There’s still so much more on my todo list for it, but I think it’s time to launch and get some feedback with what I have. Every hour, a new crossword (13×13 or 15×15) is generated at https://ift.tt/07vnXO9 If you prefer smaller/faster, every ten minutes, a new mini crossword (7×7 or 11×11) is generated at https://ift.tt/MPtn7xL You’re playing each crossword at the same time as everyone else, racing to complete it first. You can’t see what you’ve got right, until you correctly complete the entire grid. But you get some fun feedback on what other players are doing: a cell turns green if one other player has correctly solved it, orange if two other players have, and red if three or more other players have entered the correct letter in that cell. Chat is emoji-only for the first half of the game (i.e. 30 minutes for the front-page, 5 minutes for the mini). After that, it unlocks and you can chat freely. If you’re not done when the next crossword is generated, you can just stay on the current page for as long as you like and keep working to solve it. I didn’t manage to get user accounts done before my arbitrarily-imposed launch date, so everyone is anonymous for now. I definitely want to build accounts, streaks, trophies, etc. The other big thing I’m excited to build is a “team mode”. You should be able to play on a team, where you can chat freely with your team-mates, and the cell colors indicate what the other team has (collaboratively) got correct. I think that would be a lot of fun. Thanks for reading, checking it out, and for any feedback. Feel free to ask me anything, of course. https://ift.tt/HXbyrfS December 17, 2024 at 12:35AM

Show HN: NCompass Technologies – yet another AI Inference API, but hear us out https://ift.tt/cM7ukRj

Show HN: NCompass Technologies – yet another AI Inference API, but hear us out Hello HackerNews! I’m excited to share what we’ve been working on at nCompass Technologies: an AI inference platform that gives you a scalable and reliable API to access any open-source AI model — with no rate limits. We don't have rate limits as optimizations we made to our AI model serving software enable us to support a high number of concurrent requests without degrading quality of service for you as a user. If you’re thinking, well aren’t there a bunch of these already? So were we when we started nCompass. When using other APIs, we found that they weren’t reliable enough to be able to use open source models in production environments. To resolve this, we're building an AI inference engine that enable you, as an end user, to reliably use open source models in production. Underlying this API, we’re building optimizations at the hosting, scheduling and kernel levels with the single goal of minimizing the number of GPUs required to maximize the number of concurrent requests you can serve, without degrading quality of service. We’re still building a lot of our optimizations, but we’ve released what we have so far via our API. Compared to vLLM, we currently keep time-to-first-token (TTFT) 2-4x lower than vLLM at the equivalent concurrent request rate. You can check out a demo of our API here: https://ift.tt/5D3lnTJ As a result of the optimizations we’ve rolled out so far, we’re releasing a few unique features on our API: 1. Rate-Limits: we don’t have any Most other API’s out there have strict rate limits and can be rather unreliable. We don’t want API’s for open source models to remain as a solution for prototypes only. We want people to use these APIs like they do OpenAI’s or Anthropic’s and actually make production grade products on top of open source models. 2. Underserved models: we have them There are a ton of models out there, but not all of them are readily available for people to use if they don’t have access to GPUs. We envision our API becoming a system where anyone can launch any custom model of their choice with minimal cold starts and run the model as a simple API call. Our cold starts for any 8B or 70B model are only 40s and we’ll keep improving this. Towards this goal, we already have models like `ai4bharat/hercule-hi` hosted on our API to support non-english language use cases and models like `Qwen/QwQ-32B-Preview` to support reasoning based use cases. You can find the other models that we host here: https://ift.tt/TvqEwYQ. We’d love for you to try out our API by following the steps here: https://ift.tt/LJigRCN . We provide $100 of free credit on sign up to run models, and like we said, go crazy with your requests, we’d love to see if you can break our system :) We’re still actively building out features and optimizations and your input can help shape the future of nCompass. If you have thoughts on our platform or want us to host a specific model, let us know at hello@ncompass.tech. Happy Hacking! https://ift.tt/ETWhaoq December 16, 2024 at 05:37PM

Show HN: Credit reports about German companies https://ift.tt/o6hFt8R

Show HN: Credit reports about German companies Hello, In addition to my studies in computer science, I have been working on a side project. I obtain data from the Unternehmensregister, a register where every German limited company is required to publish their financial statements. These statements are published as HTML files and are completely unstructured. While financial statements often look similar, companies are not required to follow a specific structure, which often leads to inconsistently formatted statements. The use of the Unternehmensregister is completely free, so you can check out some examples. I wrote code that converts the unstructured financial statements into structured data using the ChatGPT API. This works well. Of course, there are some problems that have not yet been solved, but data extraction works well for the majority of companies. I than coded a Random Forest algorithm to estimate the probability of default for a company based on its financial statement from the Unternehmensregister. I built a website to present the structured data along with the scores. Essentially, I create a credit reports for companies. Currently, there are four companies in Germany that also create credit reports (Schufa, Creditreform, Crif, and Creditsafe). Other companies resell the data from these four providers. I provide the same services as these companies, but without including personal information such as directors or investors. The market for this service is quite large; for example, Creditreform sold over 26 million credit reports about companies in 2020. My probability of default prediction performs quite well, achieving an AUC score of 0.87 on my test data. An AUC of 0.87 means that there is an 87% chance that the model ranks a randomly selected company that defaults higher than a randomly selected company that does not default. Additionally, there are many more companies to crawl for my database. Currently, I am focusing on companies that are required to publish their profit and loss statements. For testing purposes, there are currently 2,000 companies available on my website. At the moment, the website is only available in German, but you can use Google Translate, which works ok for my website. Thank you very much for your feedback! https://bonscore.org/ December 12, 2024 at 09:59PM

Show HN: Lfi – a lazy functional sync, async, and concurrent iteration library https://ift.tt/0iPFySK

Show HN: Lfi – a lazy functional sync, async, and concurrent iteration library Hey HN! Roughly 4 years ago I started building a lazy functional iteration library for JS/TS. I had a few goals for the library: - Supporting sync, sequential async, and concurrent async iteration - Limiting it to a small number of orthogonal concepts that compose beautifully to solve problems - Making it fully tree-shakeable I built it for myself and have (mostly) been its only user as I refined it. I've used it in lots of personal projects and really enjoyed it. I recently decided it would be nice to spread that enjoyment so I created a documentation website complete with a playground where you can try out the library. I hope you enjoy using it as much as I do! Looking forward to hearing your thoughts :) https://lfi.dev/ December 12, 2024 at 01:37AM

Show HN: Gentrace – connect to your LLM app code and run/eval it from a UI https://ift.tt/gMrz6DR

Show HN: Gentrace – connect to your LLM app code and run/eval it from a UI Hey HN - Doug from Gentrace here. We originally launched Gentrace via Show HN in August of 2023. Since then, a million products have emerged in the LLM ops category. And what we've noticed is that almost none of them solve the core workflow: testing prompts, parameters, and other changes in your actual app, from a frontend where people can collaborate on the dataset, evals, or experiments to be run. So, we built that and are relaunching the company around that idea. Gentrace is the collaborative LLM app testing and experimentation platform that brings together engineers, PMs, subject matter experts, and more to run and test your actual end-to-end app. To do this, use our SDK to: - connect your app to Gentrace as a live runner over websocket (local) / via webhook (staging, prod) - wrap your parameters (eg prompt, model, top-k) so they become tunable knobs in the front end - edit the parameters and then run / evaluate the actual app code with datasets and evals in Gentrace We think it's great for tuning retrieval systems, upgrading models, and iterating on prompts. It's free to trial. Would love to hear your feedback / what you think. https://gentrace.ai/ December 11, 2024 at 02:05AM

Show HN: Chrome extension – See if HN discussed a website while you browse it https://ift.tt/w1juIYW

Show HN: Chrome extension – See if HN discussed a website while you browse it I built a Chrome extension that shows existing Hacker News posts for the current website. Background: Often when I read articles or websites, I find the associated HN posts and discussions at least as interesting as the content itself. I have been wishing for a solution to have all HN discussions for a page I am visiting directly to my fingertips, without searching. In fact, there are already extensions for it, but all of them (at the time of my search) were only developed with Manifest v2 and will therefore soon be deactivated. For this reason (and to get to know the development process of an extension better) I decided to develop a solution myself using the HN Algolia Search API and Manifest v3. The result is a simple little tool that solves my problem perfectly. Feel free to try it out - it's open source and available in Chrome Web Store. https://ift.tt/stS4pVY December 10, 2024 at 09:43PM

Show HN: FormML – A DSL for building complex web forms https://ift.tt/CS6qOMn

Show HN: FormML – A DSL for building complex web forms Hi everyone! I wrote a DSL (named Form Modeling Language) for modeling & building complex forms and am glad to share it with you now. Over the years, I’ve encountered many challenges while building complex forms from scratch—challenges that I believe are common, difficult, and yet often overlooked. These include managing interdependent fields, handling intricate validation rules, and maintain good collaboration between technical and non-technical people. FormML is my attempt to address these pain points. The project's README goes into more detail, but in short, FormML offers a model-first approach to form development (inspired by Prisma), focusing on ease of use for both developers and non-developers. Lastly, there is a design question I’d love your input: FormML has a primitive type called decimal , used for high-precision decimal numbers. Since one of FormML's design principles is to be as readable as possible to non-programmers, I’m considering renaming it to currency . However, currency might feel too narrow and not cover all applications. What do you think? - Stick with decimal ? - Switch to currency ? - Support both via aliases? Looking forward to your thoughts and feedback! https://ift.tt/FhpzP89 December 10, 2024 at 12:16AM

Show HN: Replace CAPTCHAs with WebAuthn passkeys for bot prevention https://ift.tt/RMSoWNr

Show HN: Replace CAPTCHAs with WebAuthn passkeys for bot prevention I built Nocaptcha after getting frustrated with traditional CAPTCHAs both as a user and developer. WebAuthn passkeys offered a promising alternative that's both more secure and user-friendly. What makes Nocaptcha different: - Uses WebAuthn standard instead of puzzle-solving - No need for users to remember passwords or solve puzzles - Open source Current limitation: Working with W3C WebAuthn Community Group on true passkey disposal for this use case. Looking for feedback particularly on: 1. Integration experience 2. User experience compared to traditional CAPTCHAs https://ift.tt/oC5xzEK December 9, 2024 at 12:05AM

Show HN: Checkmate, a server and infrastructure monitoring application https://ift.tt/bwdIDHY

Show HN: Checkmate, a server and infrastructure monitoring application We just released Checkmate 2.0 (formerly BlueWave Uptime). Originally designed as a simple uptime manager, Checkmate has evolved into an infrastructure monitoring tool. With the addition of our lightweight Go-based server agent (Capture) it's possible to monitor key metrics like CPU, RAM, and disk usage across remote servers. We’re now exploring new features, including enhanced notifications, advanced configuration options, DNS monitoring, and status pages (which are almost ready to launch btw). There are no plans for synthetic monitoring, APM, log management, traces etc. It'll hopefully stay as small as possible. It's still the early days for Checkmate. The project gained some traction with 31 contributors and this version itself had 13 contributors. - Server: https://ift.tt/IUDnWO4 - Agent: https://ift.tt/qs8pMOw - Demo: https://ift.tt/stlkd64 (The username is uptimedemo@demo.com and the password is Demouser1! ) https://ift.tt/IUDnWO4 December 6, 2024 at 02:38AM

Show HN: Fifty – A game where you match numbers until you clear the board https://ift.tt/5DxnB3O

Show HN: Fifty – A game where you match numbers until you clear the board Hey everyone, I'm Fabio, a very long time lurker here. Today I want to celebrate and share with you, again, a game that I conceived more than 8 years ago. I shared it last week with all its history (if you're curious) [1], but it just stayed in the "shownew" and never reached the main "show" page, hopefully this time it'll do better (:crossed_fingers:)! What changed since last week? Today I've also published the mobile apps for both iOS and Android (last week it was just web), which are also my first mobile apps ever. So I believe it's still a worthwhile post and something to show :) I'd love to know what you think about it. I'll try to answer to everyone during the day.

Show HN: Banan-OS, an Unix-like operating system written from scratch https://ift.tt/9D1a4gz

Show HN: Banan-OS, an Unix-like operating system written from scratch This is my operating system that I've been working for the past 2 years. All of the code is written exclusively by me except from ported software. banan-os has a monolithic kernel targeting x86 (i686) and x86_64 architectures. The project consists of bootloader, kernel and userspace libraries (libc, libGUI, libFont, ...). It also uses my custom C++ standard library partly based on stdc++. Currently I have basic TTY and GUI environment with some of the basic UNIX utilities like cp, ls and stat. I have basic support for USB (keyboard/mouse/storage), disks (NVMe, AHCI), custom networking stack with TCP and UDP support, and a UNIX-like filesystem with /dev /tmp /proc filesystems. The whole project is written in C++ except for my BIOS bootloader that is written in 16-bit real mode assembly. I have been testing the OS mainly on virtual machines but also frequently on real hardware. https://ift.tt/mIMuFyf December 6, 2024 at 12:24AM

Show HN: LimeJourney – open-source Customer Engagement Platform https://ift.tt/Ibexjw9

Show HN: LimeJourney – open-source Customer Engagement Platform Hello HN - I’m Tobi and I am building LimeJourney. LimeJourney is an open source customer engagement platform, a Customer.io /braze etc alternative. - For the past few weeks I have been hacking on LimeJourney during my free time and I’m inviting you to check it out and give your feedback. You can try out the demo with email and password demo@limejourney.com/demo@limejourney.com - My Grand thesis for building LimeJourney is that the channels through which we currently receive notifications will not be changing anytime soon but with the increase in data - now more than ever - businesses that will catch the attention of customers are the ones who in some shape or form are intelligently sending notifications(possibly with AI). - LimeJourney in its current form is very far off from what I hope for it to be but still solves a couple of issues I experienced when working on another project. LimeJourney is relatively cheap($50) - single base plan compared to the other big guys in the market(>$100). It is also open source and I’lld love to see folks who are able to, adopt and self host limeJourney. LimeJourney aims to play real nice with whatever you current email sending stack is and we already have integrations with Resend, AWS and are building more. The codebase is on Github => https://ift.tt/VXG85It Thank you for checking this out. You can reach me at tobi@limejourney.com https://ift.tt/Vie1yQH December 5, 2024 at 03:08AM
