Show HN: dorm: Django wrapper that lets you use its ORM in standalone manner https://ift.tt/2WeKkfY

Show HN: dorm: Django wrapper that lets you use its ORM in standalone manner dorm is a lightweight wrapper around Django that provides a minimal interface to its ORM. This package allows you to quickly integrate Django's powerful ORM into your project with minimal configuration—simply add a settings.py file to the project root and you're ready to start using it. PyPI: https://ift.tt/KZGkUCl Source: https://ift.tt/lTqk86S Give me feedback, if you do give it a try. ## Motivation I’ve always been a big fan of the Django ORM, especially its features like automatic schema migrations and the ability to perform joins without writing raw SQL. Over time, I’ve used it outside of full Django projects whenever I needed to interact with a database. Given the richness of Django’s ORM, I found other standalone ORMs (like SQLAlchemy) to be lacking in comparison. During these experiences, I kept wondering: what if I could use just the ORM, without the need for manage.py, views.py, urls.py, or any unnecessary entries in settings.py? That’s how the idea for this project was born. https://ift.tt/KZGkUCl January 1, 2025 at 02:21AM

Show HN: Cave Adventure 1976 PICO-8 port https://ift.tt/JFMiZ3q

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/p7Oq2BJ December 31, 2024 at 07:44PM

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.

Show HN: Otto-m8 – A low code AI/ML API deployment Platform https://ift.tt/vf1cHKk

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/P6seRGi Let me know what you guys think. I really would love feedback! https://ift.tt/P6seRGi December 22, 2024 at 01:39AM

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

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/DnO3Xms

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 03:33PM

Show HN: Rivet Actors – Durable Objects build with Rust, FoundationDB, Isolates https://ift.tt/mjFSais

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/4UiYEQI ). 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!

Show HN: CxReports – Low-Code Tool for User-Facing PDF Reports https://ift.tt/rG91MFA

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/JnftdzV . 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 07:15PM

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/rPVmsNU

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/DeEVGCc December 18, 2024 at 09:40PM

Show HN: Adventures in OCR https://ift.tt/rvHcSG4

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/1djSVsA 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/AOZacRH But you may also directly access the result here: https://ift.tt/hAJmy1V 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/AOZacRH December 17, 2024 at 09:00PM

Show HN: Convert PDF invoices to e-invoice XML using AI in seconds https://ift.tt/KOSE6vW

Show HN: Convert PDF invoices to e-invoice XML using AI in seconds I got approached by the finance department of a large company. There is a new regulation in Europe that mandates a defined XML-format for e-invoices for some transactions and - I kid you not - their SAP implementation wasn't able to address this. They also said that all solutions on the market were either cumbersome (think: manually typing in all fields) or required deep system integration. I thought it cannot be that hard to use AI for this and built a little invoice converter that takes your PDF invoice in whatever form it is, and outputs exactly the XML structure that is required in the regulation. Given that AI is not perfect (but surprisingly close to it!), you can manually edit all fields. Target users are companies where their current solution does not yet support the standard and that do not want to change their existing invoicing flow (incl. foreign businesses). Trying it out is free. Given this is my first real B2B tool, would love some feedback! https://ift.tt/r1GifHU December 17, 2024 at 01:52AM

Show HN: Graph-Based Editor for LLM Workflows https://ift.tt/DUBGoxM

Show HN: Graph-Based Editor for LLM Workflows Hey HN, We’re excited to share PySpur, an open-source tool that provides a graph-based interface for building, debugging, and evaluating LLM workflows. Why we built this: Before this, we built several LLM-powered applications that collectively served thousands of users. The biggest challenge we faced was ensuring reliability: making sure the workflows were robust enough to handle edge cases and deliver consistent results. In practice, achieving this reliability meant repeatedly: 1. Breaking down complex goals into simpler steps: Composing prompts, tool calls, parsing steps, and branching logic. 2. Debugging failures: Identifying which part of the workflow broke and why. 3. Measuring performance: Assessing changes against real metrics to confirm actual improvement. We tried some existing observability tools or agent frameworks and they fell short on at least one of these three dimensions. We wanted something that allowed us to iterate quickly and stay focused on improvement rather than wrestling with multiple disconnected tools or code scripts. We eventually arrived at three principles upon which we built PySpur : 1. Graph-based interface: We can lay out an LLM workflow as a node graph. A node can be an LLM call, a function call, a parsing step, or any logic component. The visual structure provides an instant overview, making complex workflows more intuitive. 2. Integrated debugging: When something fails, we can pinpoint the problematic node, tweak it, and re-run it on some test cases right in the UI. 3. Evaluate at the node level: We can assess how node changes affect performance downstream. We hope it's useful for other LLM developers out there, enjoy! https://ift.tt/KcsE4zL December 16, 2024 at 10:20PM

Show HN: I made a multiplayer crossword game https://ift.tt/pJCu9W7

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/JftQgLM If you prefer smaller/faster, every ten minutes, a new mini crossword (7×7 or 11×11) is generated at https://ift.tt/DX9CLHu 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/CShu3w2 December 16, 2024 at 11:05PM

I've spent a few weeks on this project now and it's getting to the point where I can show it off, but the API responses need a lot of work before they're usable for any downstream application.

Show HN: I designed an espresso machine and coffee grinder from scratch https://ift.tt/htcabxl

Show HN: I designed an espresso machine and coffee grinder from scratch It was a lot of work as a solo project but I hope you guys think it’s cool. When I say “we” in the website it’s only in the most royal sense possible. I also did all the photo/videography. I started out designing a single machine for personal use, but like many things it sort of spiraled out of control from there. I felt like espresso machines were getting very large, plasticky, and app-integrated without actually improving the underlying technologies that make them work. The noisy vibratory pumps in particular are from 1977 and haven’t really changed since then. So I wanted to focus on making the most advanced internals I could and leaving everything else as minimalist as possible. The pump is, as far as I know, completely unique in terms of power density and price. Without spending several thousand dollars, it was difficult to find a machine with a gear pump, and adjustable pressure was also similarly expensive but this machine has those things and costs a normal amount to buy. You can also turn the pressure way down and make filter coffee. I also saw so many people (including myself) using a scale while making espresso, and even putting a cup below the group head to catch drips, entirely negating the drip tray, so I basically designed for that! The profile of the machine is much lighter on the eyes and doesn’t loom in the corner like my old espresso machine did. And for the grinder, basically everything on the market uses conical and flat burrs that have descended from spice grinders, and the same couple of standard sizes. Sometimes larger companies design their own burrs, but only within those existing shapes. There is sort of a rush to put larger and larger burrs into coffee grinders, which makes sense, but with cylindrical burrs, you can increase the cutting surface way more relative to the size of the grinder. When grinders get too big, maintaining alignment becomes mechanically cumbersome, but the cylindrical burr can be very well supported from the inside, and there is the added benefit of hiding the entire motor within the burr itself. The resulting grounds are just outright better than all the other grinders I have used, but obviously this is a matter of taste and my own personal bias. The biggest downside for the grinder is that it doesn’t work with starbucks style oily roasts, because the coffee expands so much while traveling down through the burrs and can sometimes clog up the teeth. It doesn’t hurt the grinder but it does require cleaning (which is tool-free!). Another downside for both machines is the fact that they run on DC power so it’s best if you have a spot in your kitchen to tuck away the power brick. I also made a kit that makes the gear pump a drop-in upgrade for other espresso machines, to reduce noise and add adjustable pressure. https://ift.tt/K4w2iWV The roughest part of this process were the moments midway through development where they weren’t working at all. When the grinder is just jamming itself instantly or the fourth factory in a row tells you the part you’re making is impossible or the pump is alternating between spraying water out the side and into your face and not pumping at all. And the default thought is “Of course it’s not working, if this was going to work someone else would have already made it like this”. The route you’ve taken is fundamentally different enough that there are no existing solutions to draw on. You’re basically feeling around in the dark for months on end, burning money, and then one day, every little cumulative change suddenly adds up to a tasty espresso. And it’s not perfect yet, but you at least can see the road ahead. Anyways, this is way more than I expected to write, thank you for reading!

Show HN: Quantus – LeetCode for Financial Modeling https://ift.tt/Ts1Lqkh

Show HN: Quantus – LeetCode for Financial Modeling Hi everyone, I wanted to share Quantus, a finance learning and practice platform I’m building out of my own frustration with traditional resources. As a dual major in engineering and finance who started my career at a hedge fund, I found it challenging to develop hands-on financial modeling skills using existing tools. Platforms like Coursera, Udemy, Corporate Finance Institute (CFI), and Wall Street Prep (WSP) primarily rely on video-based tutorials. While informative, these formats often lack the dynamic, interactive, and repetitive practice necessary to build real expertise. For example, the learning process often involves: - Replaying videos multiple times to grasp key concepts. - Constantly switching between tutorials and Excel files. - Dealing with occasional discrepancies between tutorial numbers and the provided Excel materials. To solve these problems, I created Quantus—an interactive platform where users can learn finance by trying out formulas or building financial models directly in an Excel-like environment. Inspired by LeetCode, the content is organized into three levels—easy, medium, and hard—making it accessible for beginners while still challenging for advanced users. Our growing library of examples includes: - 3-statement financial models - Discounted Cash Flow (DCF) analysis - Leveraged Buyouts (LBO) - Mergers and Acquisitions (M&A) Here’s a demo video to showcase the platform in action. https://www.youtube.com/watch?v=bDRNHgBERLQ I’d love to hear your thoughts and feedback!

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 12:07AM

Show HN: Gentrace – connect to your LLM app code and run/eval it from a UI https://ift.tt/n3u84hm

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 12:35AM

Show HN: FormML – A DSL for building complex web forms https://ift.tt/1iV2gOJ

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/rmVPBXv December 9, 2024 at 10:46PM

Show HN: Replace CAPTCHAs with WebAuthn passkeys for bot prevention https://ift.tt/lWpib3w

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/FXRTQKd December 8, 2024 at 10:35PM

Show HN: Random Caplocks Prank https://ift.tt/S2QcLWV

Show HN: Random Caplocks Prank I was building a program that needed to allow a user to set a hotkey but the program lives in the taskbar so there's no UI. I decided what I would do is enable the caplock key when they click "Set Hotkey" and then they can disable the caplock key (or set it to its initial state, rather) to indicate they have finished. That project is still going but I got sidetracked by the idea that I could just build a program to randomly enable the caplock key every once in a while. This isn't a program designed to calculate child malnutrition or do anything to stop genocide etc but I was able to do it in a few hours and learn some new tricks. I hope this isn't too stupid for HN. https://ift.tt/CezPSXa November 29, 2024 at 07:12PM

Show HN: Data Connector – Chat with Your Database and APIs https://ift.tt/mZejlLq

Show HN: Data Connector – Chat with Your Database and APIs Hey HN! Wanted to share a project I have been working. Data Connector is an open source tool for interacting with Databases (Postgres, MySQL, SQLite) using natural language. Prompts are handled using a ReAct[1] agent which has access to the schema and a tool for executing queries. It also has experimental[2] support for calling APIs (OpenAPI, GraphQL) which allows for queries that can span multiple systems (Find this user's details in Clerk, etc). We have mostly been using it for managing our local development environment, but it has configurable controls for running in other environments. - Privacy Mode which never sends query results back to the LLM context, instead the result is returned to the user as JSON - Approval Mode which requires manual approval of each query before it is executed Data Connector runs within a private subnet, connects to the database and polls for new queries. There is no requirement to open traffic to the database or share credentials / connection strings. Data Connector is built using another project we are working on Inferable (also open source) which is a runtime for building and observing LLM-based agents. Would love your thoughts! [1] https://ift.tt/zC9T7Qu [2] We have been testing these with various schemas and are currently working on better handling for large OpenAPI specs, etc. https://ift.tt/NCwmjSt December 6, 2024 at 03:00AM

Show HN: Checkmate, a server and infrastructure monitoring application https://ift.tt/95J0IRV

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/w8s3izL - Agent: https://ift.tt/oTG3RZ2 - Demo: https://ift.tt/BQ6ojDS (The username is uptimedemo@demo.com and the password is Demouser1! ) https://ift.tt/w8s3izL December 6, 2024 at 01:08AM

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: Minimalboard – A intuitive and fast way to organize work https://ift.tt/RWjTpdB

Show HN: Minimalboard – A intuitive and fast way to organize work Hi HN! Organizing my work has always been frustrating because no tool seemed to fit my workflow. Every app I tried came with endless menus, complicated settings, and more clicking than actually working. If you've ever wrestled with Jira, you know the drill — its great for tracking an army of developers, but a tad overkill for my personal tasks. That's why I built Minimalboard. It combines the simplicity of a good old notepad with the visual organization of a Kanban board. Its sole focus is speed and intuitiveness. Just click to start editing, drag to rearrange, and everything saves automatically. It's a quick, clean workspace to jot down ideas, organize tasks, or capture information on the fly. I've been using Minimalboard privately for two years, and now I'm releasing it to see if I'm the only one with this peculiar obsession for simplicity or if others are equally struggling. Give it a spin and let me know what features you'd find useful. I'm curious to see how much functionality I can stuff in before it starts looking like, well, the tools I was trying to avoid!

Show HN: The Canada census data in a SQLite file; advice appreciated https://ift.tt/Fh570kc

Show HN: The Canada census data in a SQLite file; advice appreciated This is niche, I'll admit. I needed to look through the latest census data, but it was exported as multiple multi-gigabyte bespoke latin1-encoded CSV files. Pandas, Polars, and SQLite's CSV import tool weren't much help, so I shelved the project until recently, when I started taking a SQLite course online. I picked it up again, normalized the data, and now there's a database that can be queried through a SQL view that matches the headings in the original CSVs. I'm proud of the script I created to export the data, as well as automatically compress the artifact, make the diagrams and checksums, etc. This is my first time building up a big database, does my schema seem sane? I've been considering switching the counts from REALs to TEXT, since then SQLite's decimal extension can do exact calculations, but considering there's only one or two places after the decimal points in the data, I'm not sure if it's worth it space-wise. https://ift.tt/lSyWiwq December 5, 2024 at 03:20AM

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

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/0KYFnli Thank you for checking this out. You can reach me at tobi@limejourney.com https://ift.tt/ja2KTO1 December 5, 2024 at 01:38AM

Show HN: Flow – A Dynamic Task Engine for building AI Agents https://ift.tt/pLBTF2r

Show HN: Flow – A Dynamic Task Engine for building AI Agents I think graph is a wrong abstraction for building AI agents. Just look at how incredibly hard it is to make routing using LangGraph - conditional edges are a mess. I built Laminar Flow to solve a common frustration with traditional workflow engines - the rigid need to predefine all node connections. Instead of static DAGs, Flow uses a dynamic task queue system that lets workflows evolve at runtime. Flow is built on 3 core principles: * Concurrent Execution - Tasks run in parallel automatically * Dynamic Scheduling - Tasks can schedule new tasks at runtime * Smart Dependencies - Tasks can await results from previous operations All tasks share a thread-safe context for state management. This architecture makes it surprisingly simple to implement complex patterns like map-reduce, streaming results, cycles, and self-modifying workflows. Perfect for AI agents that need to make runtime decisions about their next actions. Flow is lightweight, elegantly written and has zero dependencies for the engine. Behind the scenes it's a ThreadPoolExecutor, which is more than enough to handle concurrent execution considering majority of AI workflows are IO bound. To make it possible to wait for the completion of previous tasks, I just added semaphore for the state value. Once the state is set, one permit is released for the semaphore. The project also comes with built-in OpenTelemetry instrumentation for debugging and state reconstruction. Give it a try here -> https://ift.tt/FCiafpD . Just do pip install lmnr-flow. (or uv add lmnr-flow). More examples are in the readme. Looking forward to feedback from the HN community! Especially interested in hearing about your use cases for dynamic workflows. Couple of things on the roadmap, so contributions are welcome! * Async function support * TS port * Some consensus on how to handle task ids when the same tasks is spawned multiple times https://ift.tt/FCiafpD December 2, 2024 at 10:51PM
