Show HN: Dolce – Get notified if something (bad) happens to your containers Hi HN, while I was on vacation this year the shop of my wife was suddenly down and we only noticed once the emails of customers rolled in. After fixing it on my phone I thought there has to be a better way to notice when your docker container die or are in a restart loop for whatever reason. Now I know there are lots of tools like healthcheck.io and monocker, however none seemed to match my simple use case of getting notified _via email_ when the running– or health-status of any docker container changes. So I did what every SE would do in that case and hacked another solution but this one is mine :). I also always wanted to do a project with deno and get up to speed on typescript. This was also a great reason to finally look into using GitHub Actions to automate some of the tedious tasks. Fun fact: After reading on here about Deno Queues, I rewrote the message buffering and backoff completely and could greatly simplify the code. TL;DR - What is this: Get notification via - EMail (BYOSMTP) - Discord - Telegram if any (or only selected) containers on your host die or change their health status. I also tried to handle unexpected restarts of the container the tool is running in gracefully without loosing any events that happened before and even while the service was down. To make sure you are not spammed by notifications if a container goes into a restart loop, there is also a configurable exponential backoff function. I tried to make using the tool as easy as possible (by getting inspired on how monocker is set up). I would love to get some feedback and hear what you think (also if I just missed the perfect tool for the job: let me know, however the journey was quite fun). https://ift.tt/Gs89Dvy September 29, 2023 at 11:11PM

Show HN: Generative Fill with AI and 3D Hey all, You've probably seen projects that add objects to an image from a style or text prompt, like InteriorAI (levelsio) and Adobe Firefly. The prevalent issue with these diffusion-based inpainting approaches is that they don't yet have great conditioning on lighting, perspective, and structure. You'll often get incorrect or generic shadows; warped-looking objects; and distorted backgrounds. What is Fill 3D? Fill 3D is an exploration on doing generative fill in 3D to render ultra-realistic results that harmonize with the background image, using industry-standard path tracing, akin to compositing in Hollywood movies. How does it work? 1. Deproject: First, deproject an image to a 3D shell using both geometric and photometric cues from the input image. 2. Place: Draw rectangles and describe what you want in them, akin to Photoshop's Generative Fill feature. 3. Render: Use good ol' path tracing to render ultra-realistic results. Why Fill 3D? + The results are insanely realistic (see video in the github repo, or on the website). + Fast enough: Currently, generations take 40-80 seconds. Diffusion takes ~10seconds, so we're slower, but for the level of realism, it's pretty good. + Potential applications: I'm thinking of virtual staging in real estate media, what do you think? Check it out at https://fill3d.ai + There's API access! :D + Right now, you need an image of an empty room. Will loosen this restriction over time. Fill 3D is built on Function ( https://fxn.ai ). With Function, I can run the Python functions that do the steps above on powerful GPUs with only code (no Dockerfile, YAML, k8s, etc), and invoke them from just about anywhere. I'm the founder of fxn. Tell me what you think!! PS: This is my first Show HN, so please be nice :) https://ift.tt/kW9lu1d September 29, 2023 at 02:11AM
Show HN: The Tomb of Ramesses I in the Valley of the Kings Hey all, I’m coding up a new tour system for my 3d Egyptian work. After the last feedback, I focused on building more interactive content and fx into the guided tours with sound and telling the mythology in the wall art. I’d love feedback with the new version – this is built with vanilla Three.js and footage captured on my iPhone 12. For various fx, I coded many of my own shaders based on work by https://twitter.com/akella and others on ShaderToy, so I’m keen to test on more devices. As the hacker, so the (ancient) painter. https://ift.tt/SBe506d September 26, 2023 at 06:34PM
Show HN: A simple API/CLI for scheduling HTTP requests Hi HN! This is something I've been tinkering on for the past couple months. It's basically just an API/CLI for scheduling delayed or recurring jobs as HTTP requests. I initially built it as a personal tool to save myself a bit of time on little side projects where I've needed scheduled/recurring alerts, but decided it could be a good opportunity to practice building out a nice landing page [0] and documentation [1]. And who knows, maybe someone else will find it useful ¯\_(ツ)_/¯ The tool relies heavily on Elixir's Oban [2] library for managing jobs, and Mintlify [3] for documentation. I also shamelessly stole most of the frontend design from Resend [4] because I'm a fan of the aesthetic and thought it would be good for my design chops to use their design as a guide. I also discovered Radix [5] UI while working on this, which ended up being immensely helpful for moving quickly on the frontend. Anyways, I almost certainly spent a bit too much time on small UX details that are most likely utterly inconsequential, but it was a fun exercise in polish :) All feedback is welcome!

Show HN: Using LLMs and Embeddings to classify application errors Hi Hacker News! We’re Vadim and Chris from Highlight.io [1]. We do web app monitoring and are working on using LLMs/embeddings to add new functionality to our error monitoring product. Given that there’s a lot of founders/engineers using LLMs in their products, we figured we’d share how we built the new functionality, their impact on our workflows, and how you can try it out. Our goal was to build two features: (1) tagging errors (e.g. deeming an error as “authentication error” or a “database error”); and (2) grouping similar errors together (e.g. two errors that have a different stacktrace and body, but are semantically not very different). Each of these rely heavily on comparing text across our application. After some experimentation with the OpenAI embeddings API [3], we went ahead and hosted a private model instance of thenlper/gte-large (an open-source MIT licensed model), which is a 1024-dimension model running on an Intel Ice Lake 2 vCPU machine on Hugging face [4]. Our general approach for classifying/comparing text is as follows. As each set of tokens (i.e a string) comes in, our backend makes a request to an inference endpoint and receives a 1024-dimension float vector as a response (see the code here [5]). We then store that vector using pgvector [6]. To compare any two sets for similarity, we simply look at the Euclidian distance between their respective embeddings using the ivfflat index implemented by pgvector (example code here [7]). To tag errors, we assign an error its most relevant tag from a predetermined set decided by us. For example, if we tag an error as an "authentication error" or a "database error", we can allow developers to have a starting point before inspecting an issue.(see the logic here [8]). Anecdotally, this approach seems to work very well. For example, here are two authentication errors that got tagged as “Authentication Error”: * Firebase: A network AuthError has occurred * Error retrieving user from firebase api for email verification: cannot find user from uid. We also use these error embeddings to group similar errors. To decide whether an error joins a group or starts a new one, we decide on a distance threshold (using the euclidean distance) ahead of time. An interesting thing about this approach, compared to using a text-based heuristic, is that two errors with different stack traces can still be grouped together. Here’s an example: * github.com/highlight-run/highlight/backend/worker.(*Worker).ReportStripeUsage * github.com/highlight-run/highlight/backend/private-graph/graph.(*Resolver).GetSlackChannelsFromSlack.func1 Both reported as `integration api error` as they involve the Stripe and Slack integrations respectively. The neat thing is that the LLM can use the full context of an error and match based on the most relevant details about the error. We have rolled out a first version of the error grouping logic to our cloud product [9], and there’s a demo of all the functionality at [2]. Long-term, if the HN community has other ideas of what we could build with LLM tooling in observability, we’re all ears. Let us know what you think!

Show HN: Unity like game editor running in pure WASM In the wake of all the Unity nonsense, just wanted to toss the Raverie engine into this mix :) We’re building off a previous engine that we worked on for DigiPen Institute of Technology called the Zero Engine with a similar component based design architecture to Unity. Our engine had a unique feature called Spaces: separate worlds/levels that you can instantiate and run at the same time, which became super useful for creating UI overlays using only game objects, running multiple simulations, etc. The lighting and rendering engine is scriptable, and the default deferred rendering implementation is based on the Unreal physically based rendering (PBR) approach. The physics engine was built from the ground up to handle both 2D and 3D physics together. The scripting language was also built in house to be a type safe language that binds to C++ objects and facilitates auto-complete (try it in editor!) This particular fork by Raverie builds both the engine and editor to WebAssembly using only clang without Emscripten. We love Emscripten and in fact borrowed a tiny bit of exception code that we’d love to see up-streamed into LLVM, however we wanted to create a pure WASM binary without Emscripten bindings. We also love WASI too though we already had our own in memory virtual file system, hence we don’t use the WASI imports. All WASM imports and exports needed to run the engine are defined here: https://ift.tt/w23W0YV... The abstraction means that in the future, porting to other platforms that can support a WASM runtime should be trivial. It’s our dream to be able to export a build of your game to any platform, all from inside the browser. Our near term road-map includes getting the sound engine integrated with WebAudio, getting the script debugger working (currently freezes), porting our networking engine to WebRTC and WebSockets, and getting saving/loading from a database instead of browser local storage. Our end goal is to use this engine to create an online Flash-like hub for games that people can share and remix, akin to Scratch or Tinkercad. https://ift.tt/vzRO9AH https://ift.tt/HzMW2rP September 26, 2023 at 11:28PM
Show HN: Zero-dependency Java framework out of beta I am happy to announce my minimalist zero-dependency web framework, Minum, is out of beta. https://ift.tt/gDBUOpJ You will be hard-pressed to find another modern project as obsessively minimalistic. Other frameworks will claim simplicity and minimalism and then, casually, mention they are built on a multitude of libraries. This follows self-imposed constraints, predicated on a belief that smaller and lighter is long-term better. Caveat emptor: This is a project by and for developers who know and like programming (rather than, let us say, configuring). It is written in Java, and presumes familiarity with the HTTP/HTML paradigm. Driving paradigms of this project: * ease of use * maintainability / sustainability * simplicity * performance * good documentation * good testing It requires Java 21, for its virtual threads (Project Loom) https://ift.tt/6u3hrgC September 25, 2023 at 11:37PM

Show HN: Basketball Play Designer In a company hackathon this weekend, I thought it would be fun to build a basketball play designer. Essentially, you enter some information about the type of play you want, and it generates a play following these requirements. I was imagining it might be useful for stuff like: 1. Designing personalized plays for first-time coaches: "Give me a play that gets my shooting guard an open three-pointer. My shooting guard shoots the best from the right wing, and my point guard has a weak left hand. My center sets great screens, so have my center set an off-ball screen for my shooting guard." 2. Brainstorming novel plays for long-time coaches: "Generate a novel play out of the UCLA set." It is loaded in with an example play, so make sure to hit the buttons to generate new plays with the entered information. The animation generation is based on the play-by-play and is a bit finicky, so you can try to generate new play-by-plays/animations if the first ones don't work well. It's still a bit rough around the edges, but I'd love to know what people think! https://ift.tt/sng6AQD September 24, 2023 at 01:06AM
Show HN: A “CRM” for your personal relationships Android: https://ift.tt/gOioKG0... iOS: https://ift.tt/RGWgqQH We know life can be busy. And we often struggle to make time for the people that matter most to us. According to a Harvard study from 2021, "36% of all Americans [...] feel “serious loneliness.”" [1] We created an app to help people focus on their most personal relationships and guide them through forming more meaningful connections with them, in the hopes to combat the "Loneliness Epidemic". We just launched the first iteration - call it an MVP if you like - something to validate our ideas and get the conversation started. We are looking for people to try out what we have built and share their thoughts. The functionality is very basic for now, but we are planning to expand based on our users' feedback. Here is what you can do today: * Tell us who the people are that matter most to you * Get daily reminders to reach out to them * Send them virtual postcards with over 50 handcrafted designs [1] https://ift.tt/EwxTh61 https://ift.tt/hst879T September 23, 2023 at 10:51PM

Show HN: Learn piano without sheet music I always found sheet music way too hard to read - and I literally spent a year at a company building a sheet music rendering engine. I wanted an app that would display music like the tutorials on YouTube, but not be focused on upselling lessons etc. like most current apps, and also would let me import my own files This works on MIDI files. If it’s a valid midi it probably plays. Since releasing, I did add a subscription for classical music - on a theory that most normal users don’t know what a midi file is. It changed about a month ago from an up front price to in app purchases and/or a subscription - which has absolutely tanked revenue so far - but maybe it will pick up Would love to hear your thoughts and if you have any suggestions! https://ift.tt/0HvYyLE September 22, 2023 at 06:32PM

Show HN: Corgi – on-demand, 1-on-1 tutoring Hey all — I’m Sameer, a software engineer and longtime math/CS tutor who’s just launched an on-demand tutoring platform called Corgi. The product is a mobile app (currently iOS only) that allows users to request and receive tutoring help whenever they want it, for as little or as long as they need. Here’s how it works: 1. User selects a subject, adds a brief summary of what they need help with, and submits their request 2. All tutors who are online and qualified in that subject receive a notification that someone needs help 3. The first tutor to accept the request gets matched with the user, and both parties are placed in a in-app video chat session 4. The user works with the tutor for as long as they need 5. When the session is complete, the user is charged for the time they used (currently billed at $1/minute, rounded to the nearest minute) and the tutor receives 80% of the student fee As a starting point, the only subject we’re offering is SAT math help, but we plan to expand to other subjects in the near future. I built Corgi because 1) tutoring is a lifelong passion of mine, and 2) I haven’t found a quality, on-demand tutoring service that currently exists, but I believe it’s something that could really help students. The idea here isn’t to try and replace the traditional tutoring model (i.e. working with the same tutor on a consistent basis over a long period of time) but to supplement existing resources with an office hours-like service that can provide immediate help (e.g. at the exact moment when someone is struggling with homework, or is studying for an imminent exam). Eventually, I’d like to offer this platform directly to schools or districts, so that students can use it irrespective of ability to pay. There is at least one major player in this space doing something similar ( https://paper.co ) but from my own research they seem to have a lot of issues (e.g. students getting matched with tutors who aren’t qualified in their subjects, tutors working with many students simultaneously despite the company claiming the tutoring is all 1-on-1) and districts who previously signed contracts with them don’t seem keen on continuing their relationships ( https://ift.tt/zLBVA6o... ). I’ve also been a tutor on some of the existing traditional tutoring platforms (e.g. Wyzant) and have found the experience frustrating (mainly due to unfairly low compensation combined with a struggle to match with students). My goal with Corgi is to build something that provides real value and a positive experience for both the tutors and students who use it. I’ve spent the last week or so recruiting an initial batch of tutors, and am now kicking off the process of finding students to help test it out. I’m also building out some additional features to help make the actual tutoring sessions feel a little smoother (e.g. browser-based sessions to allow usage from any device, virtual whiteboards for easier collaboration). I’d appreciate any and all feedback the HN community has to share, positive or negative! https://ift.tt/n5ObIdG September 22, 2023 at 07:53AM

The actual priorities get missed amongst all other things in life. With the launch of Gen AI in almost all aspects of our lives, i decided to build something that can assist me in finding the right priorities and staying on them. This has helped me out for the past couple of days. I am using Openai apis for task breakdown and Daily planning bot and the rest of the site is built using Django, JS, and Tailwind. I have tried a lot of productivity tools throughout the years and Pomodoro and timer-based focused work has worked out best for me.

Show HN: Pendable - high performance email sending with Amazon SES Hi HN, Today we announce Pendable (Pendable.io), which is a production-grade email sending platform using Amazon SES. Pendble does parallelized email sending, dynamic priority queues, scheduled future delivery, email events, active throttling based on bounces and complaints, spam domain filtering, email logs and resend options, all using your existing Amazon SES setup. To get started, use our API instead of SES and start routing your emails through Pendable. In our day job, we develop bespoke custom loyalty solutions for enterprise customers and have been doing that over a decade. We use SES extensively as it is cost-effective and robust but we found a lot of gaps and decided to build the features instead of moving to solutions like SendGrid or MailChimp. With Pendable, you can continue using your SES account to send emails, while Pendable makes it robust and high-performant. Furthermore, we provide an easy to use monitoring dashboard that you can directly provide to your internal stakeholder teams. This is our first attempt at a startup and so we highly value your feedback and suggestions for new features. We are planning to build features like Unsubscribe Preferences and support for SES email templates.

Show HN: macOS GUI for running LLMs locally Hello HN, I've been working on this project for a while, and it has been in an "open" beta for some time. I finally believe it's ready for its first release. I hope you like it. Here are some potential questions that may arise: 1. How does it compare to LM Studio? It's likely that if you're already using LM Studio, you'll continue to do so. This project is designed to be more user-friendly. 2. Is it open-source? No, it is not. 3. Does it use any open-source libraries? Yes, it uses llama.cpp and a few others, as indicated in the license information included with the application. 4. Why is not using electronjs? Two reasons, I wanted total control over the whole tech-stack and second, I wanted to be able to send this to my friends over iMessage. 5. Does it support Intel macs? It should, but I couldn't test it. 6. Does it support older macOS? 12.6 is the lowest version at the moment. 7. Is XXX a bug? Probably :) https://www.avapls.com/ September 19, 2023 at 01:21AM
Show HN: A murder mystery game built on an open-source gen-AI agent framework Hey HN, Michael and Scott here. We’re open-sourcing an interactive murder mystery featuring LLM-driven character agents. Solve the mystery by finding clues, taking notes, and interrogating agents. They all have distinct motives, personality, and can impact the game in different ways (attacking you, running away, etc). Try it out, it’s pretty fun! We’re also open-sourcing the framework that we used to make and refine the agents. The goal is to create an intuitive interface for storytellers to create, debug, and test game agents. We then take those game agents and expose an API beyond just chat - such as actions, player guardrails, emotional queries, etc. We’re not done yet - there are a lot more features coming on the way: scenario-based agent evals, agent-storyline consistency management, automatic agent generation, etc. We would love to hear your feedback.

Show HN: LLM Powered Keyboard [video] Hey HN, I'm excited to share Taikoboard, a mechanical keyboard with LLM powered autocomplete. I made this keyboard for myself so I could use LLM-powered autocomplete in apps that didn't have this feature. Although more apps have started integrating LLMs, there's a large number of software tools that don't support this. Taikoboard bridges that gap, making the AI autocomplete experience universal. Would love to hear feedback, answer questions, or discuss potential use cases you see for Taikoboard. https://www.youtube.com/watch?v=BbMSWZKrrcI September 18, 2023 at 05:44PM
Show HN: Hyperboot – Run Linux distros on your Chromebook Greetings, HN community! I'm excited to introduce Hyperboot, the spiritual successor to the Eupnea project's Depthboot, designed to simplify the process of running Linux on Chromebooks. A brief background on Hyperboot: Recently, the Eupnea project's developer announced the discontinuation of the project. This news left me and several others deeply disappointed. Determined to keep the vision alive, I initiated the Hyperpnea revival project for Depthboot. I'm here to address any inquiries or feedback you may have. Feel free to ask questions or share your thoughts! Looking forward to engaging with you all. https://ift.tt/gRC0nq8 September 18, 2023 at 05:23AM
Show HN: Live Train Webcams Our son is really into trains. He was home sick a few weeks ago and we found that there are several YouTube channels that have live video feeds from various train stations or railway clubs around the US. He really liked it, but he kept wanting to know when the next train was going to show up so he could see it. I built this small website at https://ift.tt/YMsJwU0 which shows the time to the next train (Pacific time) and will automatically rotate channels to find the next train. It uses the Amtrak live train data today. In the future I might add other agencies, since a few of these stations do have more than one agency that services them and there are also some international stations I found feeds for. Hope this may be of some use for those of you with your own railfans in your life :) https://ift.tt/YMsJwU0 September 18, 2023 at 02:33AM
Show HN: Me and my buddy made $20 with a Stripe link and a Tweet Hi there, So a buddy a couple of days ago came up with the idea for a new SaaS product regarding gpt and image generation. We did a quick MVP that barely works, it breaks almost 50% of the time but we still wanted to validate the idea before going all in. We have almost 1k followers on Twitter together. Did a quick post describing the idea with a stripe link in the comments with a 5$ value, no landing page, and no shipped product. In exchange, the buyers become beta users. Around 30 mins later we got our first sale next 30 mins another 5$ and so on. Do we consider the idea validated? The short answer is no, We gained some initial momentum but we can't call it a business yet, not until we are starting to get recurring revenue. What next? We created a notion file with multiple marketing channels we plan to test out and see which one is the best. We also created a list full of websites to submit our product and we are tracking the traffic we are going to get from each of them. PS: If you are curious, this is the product https://coverposts.com/ September 17, 2023 at 08:46PM

Show HN: I made a browser extension for building your own custom HN themes Hi HN! I’ve spent the last few weeks writing a browser extension that lets users write their own HN themes using Handlebars and CSS. It works by converting the current Hacker News page’s content into an object that is made available to the user-defined Handlebars templates. There is a built-in code editor that makes writing themes super easy and you can see changes in real-time. If you don’t want to write a theme from scratch, there are premade themes available or you may import one made by somebody else. It is shipped with Bootstrap so you can get pretty far without needing to write a lot of custom CSS. Material icons are also included so your themes get iconography out of the box. Any theme can be toggled into dark mode with a single click. It is open-sourced under the MIT license so feel free to use any of the code in the linked repo[0]. Additionally, I’ve put together a short demo video on YouTube[1]. If you decide to check it out, let me know of any feedback and please share any themes you create! I’d be happy to answer any questions. [0] https://ift.tt/yfTclrp [1] https://youtu.be/6DxLJQrKXa0 https://ift.tt/VW1bhv6 September 17, 2023 at 07:16PM

Show HN: Prompt-to-Publishable-Book I'm thrilled to share something I've been working on for the past year. We built your dream tool for turning the idea you wished could be a book into a book - we call it Omniscience. It goes from a single prompt to a high-quality, cover-to-cover novel or non-fiction book. You can sample our non-fiction by reading Revolutionizing Life Design ( https://t.co/zfdBALBkNw ) and Unhinged Genius ( https://t.co/JVNXAJAqsE ) or our fiction by reading Omni Genesis. https://t.co/5WSQ3jsaA5 Plenty of other great works are available in the library, and you can follow our book prompting guide to generate your own masterpiece in our book writing interface. Prompt detail & complexity is king. You can take it from the words of one of our early evangelical customers: "Your tool has been a veritable boon for us, resembling a gift from Heaven." You'll get full hardcover and paperback cover art, the summary, full text & outline, and even recommendations for the Amazon keywords you should use. Everything you've written over the course of your life can be behind the book - uploading your data by syncing with Drive, choosing a website, or sending a folder or file from your computer and selecting it in the book writing interface will infuse the book with the knowledge you've chosen. From now until 24 hours after the launch, your first book will be free. Every book after that is paid. Happy reading & writing!!

Show HN: Nue – A React/Vue/Vite/Astro Alternative Author here. I've been working on this for the past ~12 months, lately full-time. I'm releasing two things today: 1. Nue JS: https://ift.tt/LHTk5V6 — A tiny (2.3kb minzipped) JavaScript library for building user interfaces. It's like React/Vue core, but there are no hooks, effects, props, or other unusual abstractions on your way. Know the basics of HTML, CSS, and JavaScript and you are good to go. Nue JS supports server-side rendering (SSR), reactive components, and "isomorphic" combinations. It takes inspiration from Vue 2.0 and Riot.js. (I'm actually the original author of Riot). 2. Nue ecosystem: https://ift.tt/7uhzgaq — This is the ultimate goal and once all the sub-projects are finished, Nue will be a serious alternative to things like Vite, Next.js, and Astro. The thing is that I'm not happy with the current state of web development, so I want to write a completely new ecosystem from scratch. I'm taking advantage of the "old" innovations like progressive enhancement, separation of concerns, and semantic web design. Benefits highlighted here: https://nuejs.org/why/ All projects will be released under the MIT license. Happy to answer any questions. https://nuejs.org September 14, 2023 at 04:41PM
Show HN: A vector database with semantic SQL-like filtering Hi HN! It’s always bothered me that there’s no real equivalent of SQL WHERE for vector content. Filtering is one of the cornerstones of a modern database — but vector DBs only support either top-k sort, which is only useful for fuzzy search, or metadata filtering, which isn’t semantic. I’ve found myself wanting all the results matching my semantic query, not just k! Aside from data analysis, it's relevant if you’re trying to do any LLM reasoning: you don’t make good decisions or reach good conclusions by considering a small subset of information. So, we’ve designed a filtering primitive on top of vectors and assembled a demo on customer reviews from Trustpilot, Yelp, App Store, etc. You can select any brand/restaurant/app, and slice the review data however you want. The filter should find all matching documents, not just the top-k. Check it out at https://ift.tt/HJgL4sO ! Not super optimized yet, and really just an exploration, but hopefully gets the point across. FAQ: - Can I try it on my own data? Sure, shoot me a message at hello [at] emberml [dot] com. - How does it work? We’ve built a custom vector-based index, and we learn a high-quality decision boundary between relevant and irrelevant vectors at query time. You can think of it as forming a few-shot classifier each time. - What’s the catch? It’s far slower and less scalable than KNN/ANN right now. But I’d rather solve quality before trying to scale up quantity; tbh I’m not satisfied with vector DB performance even at @ N=1,000. A hot take, maybe? - Why don’t you just classify the data beforehand? Unstructured data has too many degrees of freedom, so it’s hard to anticipate every search/filter a priori. Our approach is somewhat analogous to schema-on-read. https://ift.tt/10rk5b2 September 14, 2023 at 11:34PM

Show HN: A surprisingly effective way to predict token importance in LLM prompts We explored a novel method to gauge the significance of tokens in prompts given to large language models, without needing direct model access. Essentially, we just did an ablation study on the prompt using cosine similarity of the embeddings as the measure. We got surprisingly promising results when comparing this really simple approach to integrated gradients. Curious to hear thoughts from the community! https://ift.tt/2sxqEZv September 11, 2023 at 10:59PM
Show HN: Slotmachine, to book and free server ports at scale This is a very specialized Go library and, frankly, somewhat of a straw man: I've found myself needing to quickly assign ports on servers with a high density of highly ephemeral inbound/outbound connections where the protocol relies on a specific port number. Obviously, running sequentially through a list of ports until I find one I have not already allocated does not perform very well. I was surprised when I did not find anything already addressing this need. So, this is the straw man part: surely I missed it! Anyway, should you ever need something like that... here it is. https://ift.tt/UR0SQdq September 11, 2023 at 10:09AM

Show HN: Productonboarding.com – Mobbin for SaaS product onboarding Hey Hackernews, Eric here! Wanted to share a new website we just built called productonboarding.com (Next.js and RSC). The site has screenshots and videos of product onboarding from companies like Figma, Notion, Framer, and more. It’s sort of like Mobbin for web-based product onboarding. We build a lot of product onboarding at our startup Frigade, and over the last year we’ve put together an internal library of hundreds of product onboarding examples that we refer to all the time with customers. It helps them find and copy patterns that work at other companies so they don’t need to create net new experiences or A/B test their way into the best performing pattern from scratch. Given it's been so useful to us, we decided to open it up to the world. We bought productonboarding.com and have started adding examples from our collection and made them browsable and sortable. We’re planning to add new examples weekly. Hope this is helpful to any of you who are currently thinking through building new onboarding experiences. Would love any ideas and feedback. Thanks! https://ift.tt/9QpVSDa September 9, 2023 at 10:26PM
Show HN: Which is faster? Puppeteer, Playwright or Selenium Hey Everyone, I just ran a [rather silly] race between Puppeteer (JS), Playwright (Python) and Selenium (Python) to see which one would be fastest on a simple scrape (using Google Colab so you can also run it) Far from a comprehensive benchmark, this race is 100% free from advanced configurations, multi-threading or anything complicated. It just opens Wallapop (a second hand marketplace in Spain) and times how long it takes to extract the first 2000 results of a search. If you like this simple format, have any ideas on how to improve a race like this or have a strong urge to prove Ward Cunningham wright, let me know in the comments! https://ift.tt/Rph7dg9 September 9, 2023 at 04:54PM
Show HN: Rivet – open-source AI Agent dev env with real-world applications We just launched Rivet, the open-source visual AI programming environment! We built Rivet, because we were building complex AI Agent applications at Ironclad. It unlocked our abilities here, and we're excited to make available to the entire community. Backstory: A few months ago, inspired by things like LangChain and LlamaIndex, we started building an AI agent that could work with legal contracts. Unfortunately, we couldn't just use retrieval augmented generation (RAG), because a lot of contracts are basically identical (many chunks with near-identical embeddings), except for a few key details. So, we turned to things like ReAct and AutoGPT for inspiration. At first, things went great. We were adding agent capabilities, doing chain-of-thought prompting. But then we hit a wall. The agent became too complex. We had debugger breakpoints on almost every line of code, but we still had no idea where the agent was breaking. Every change we made destabilized something else. After two weeks of fumbling, I decided to end the project. But one of my teammates, Andy, didn't give up. The following week, he showed me v0 of Rivet. He'd used it to refactor and improve our existing agent. I was skeptical... it just seemed like a visual programming environment, and I was not a fan. But I gave it a shot, and suddenly found myself able to add new skills to the agent, debug brittle areas with ease, and update prompts with confidence. Rivet is a game-changer. And more than that, it makes building with LLMs super fun. What exactly makes it different? First, the debugger is incredible. You have to experience it to believe it. You can update a graph, and then immediately run it, and see where it succeeded or failed. Even better: you can attach Rivet as a remote debugger, and watch your agent graphs execute in your app. Second, visual programming is actually a game-changer for prompting LLMs. I don't know why exactly, but it's way easier to understand and organize your work when you have an extra dimension to work with. Finally, Rivet is built to be embedded into a larger application (TypeScript for now, but we've also found a way to run it in Python). Beyond importing Rivet as a dependency, you can also define "external functions" dynamically at run-time. It feels pretty sketchy to give a LLM a key and unfettered access to an API. With Rivet, you can give it access to a specific set of defined functions, potentially pre-scoped to the access level you want. ...Sorry that was long. If you read this whole thing, thank you! We're really excited to hear what you think! We just launched our first Rivet-based application at Ironclad, and we've been working with companies like Sourcegraph, Attentive, AssemblyAI, Bento, and Willow to make Rivet useful for others. https://ift.tt/wMjthz0 September 8, 2023 at 06:59PM

Show HN: HackYourNews – AI summaries of the top HN stories Hey there HN! I wanted to share a pet project of mine. I built HackYourNews [1] to scratch a personal itch: Knowing which stories to focus on while browsing aimlessly (though there is a certain joy in that, as well!) HackYourNews uses OpenAI's gpt-3.5-turbo to summarize the destination article as well as the comments section. Summarization of the article is always cached, while summaries of the comments are regenerated if the comments count is >10% (or >10 comments) different. While I styled the homepage to welcome HNers, my preferred view is the Mobile view, accessed from the navbar. This no-frills view honors OS-level dark mode and is easy to skim on any device. Tried to keep the site minimal. The only JS is Cloudflare's privacy-preserving analytics [2], just to gauge interest. This is the first time I'm releasing something to the wild. Hope you find this useful! The frontend is pure HTML+CSS. The backend is NodeJS (Puppeteer) + Python with the excellent Microsoft Guidance [3] library to interface to OpenAI's API.

Show HN: Frcntl – community for fractional developers and designers Hey HN! In 2017, I launched Moonlight to help engineers find part-time, remote jobs. Combining part-time with remote work was a big leap then, so we quickly narrowed our focus to just remote work. Lately, I've seen many talented friends and colleagues moving into part-time fractional roles. They're carving out more personal time while maintaining the same income. Personally, fractional work has empowered me to pursue my entrepreneurial goals without worrying about runway or funding. It's no surprise that hiring managers are gravitating towards this, especially as companies are emphasizing efficiency instead of all-out growth. From our experience with Moonlight, we found that most engineering managers prefer hiring for ongoing, direct work relationships rather than transient, fixed-scope projects. These enduring relationships proved to be mutually beneficial, providing stability for companies and workers in a working style legible to both. Today I'm launching FRCTNL - a community of fractional developers, designers, and marketers. Distinct from traditional marketplaces focused on top-down projects, FRCTNL focuses on often-overlooked bottoms-up, relationship-centric "staff augmentation" roles. Hiring managers seek quality candidates referred by their existing team, and direct relationships with talent — this is the niche FRCTNL aims to serve. FRCTNL operates on a referral model, where members help swap and share opportunities with each other. The underlying hypothesis is that there is latent demand for fractional talent, and that connecting with existing fractional workers is the best way to find those open roles. I'm convinced that our fractional worker network will streamline hiring for companies and further mainstream part-time roles. Take a look, and let me know if you have any questions or feedback! https://www.frctnl.xyz/ September 7, 2023 at 08:26PM
Show HN: Curated custom search engine portal Hey friends, a little background - A friend of mine who’s also a newsletter writer once told me that when he’s interested in certain topic he would like to know the opinion of some of his favorite writers on the same topic. He would use Google to search something like discomfort site:sive.rs, and then expand his search across various authors he admires. It turns out that Google’s programmable search engine does exactly that. By simply adding a few websites (much like subscribing to newsletters or RSS feeds), we can craft a search engine tailored for our specific needs. I think that's a great idea - more signal and less noise. So I built a portal to facilitate sharing personal curations https://ift.tt/1IdWAl3 .

I'm in the middle of my parental leave, and this was a project that came out of me looking for the fastest/smallest CSV parser. It all started so innocently, and then turned into a benchmark-validation-athon; the library itself took ~2 weeks to write, but the performance comparisons took another ~4 weeks (on and off).

Show HN: Nix Snapshotter – Native understanding of Nix packages for containerd Hello! This is Edgar and Robbie and we built nix-snapshotter. nix-snapshotter brings native understanding of Nix packages to containerd. We built this because Nix is a great fit for making efficient containers. They don't need an OS because Nix captures all dependencies exactly. However, the current process of creating Nix images is subpar because one needs to transform Nix packages into a format that container runtimes understand. Using nix-snapshotter, instead of downloading image layers, packages come directly from the Nix store. Packages can be fetched from a binary cache or built on the fly if necessary. All existing non-Nix images continue to be supported, and Nix layers can be interleaved with normal layers. nix-snapshotter also provides a CRI image service, which allows Kubernetes to resolve image manifests from Nix directly too. This enables for the first time, fully declarative Kubernetes resources, all the way down to the image specification and its contents. With this, you can even run pure Nix images without a Docker Registry at all, if you wish. We'd love for you to try it out, there is a one-liner for Nix users to boot a VM with everything pre-configured: https://ift.tt/jouR0Xv https://ift.tt/jouR0Xv September 6, 2023 at 10:24PM
Show HN: Trellis – open-source Python framework to build DAG-based LLM workflows Hey HN! Trellis is an open-source framework for programmatically orchestrating LLM workflows as Directed Acyclic Graphs (DAGs) in Python. My friend and I started working on this a few weeks ago after we tried building applications using mainstream LLM frameworks, and faced all the common complaints (too abstracted, hard to customize, bad docs/support). After talking to a few other people building with LLMs, we also noticed that these frameworks were not inherently built to support DAG-based LLM workflows. We designed Trellis to be as minimal and flat as possible, so developers can have lower level control over their DAGs. Trellis is composed of only three abstractions: Node, DAG, and LLM. Node: the atomic unit of Trellis. Nodes are chained together to form a DAG. Node is an abstract class with only one method required to implement. DAG: a directed acyclic graph of Nodes. It is the primary abstraction for orchestrating LLM workflows. When you add edges between Nodes, you can specify a transformation function to reuse Nodes and connect any two Nodes. Trellis verifies the data flowing between Nodes in a DAG to ensure the flow of data is validated. LLM: a wrapper around a large language model with simple catches for common OpenAI errors. Currently, the only provider that Trellis supports is OpenAI. Check out our docs if this sounds interesting: https://ift.tt/0f47XEN... We'd love it if you tried hacking with it and give us any feedback you have! :) https://ift.tt/DFuBoKi September 6, 2023 at 07:34AM

Show HN: Keep – GitHub Actions for your monitoring tools Hi Hacker News! Shahar and Tal from Keep here. A few months ago, we introduced here at HN ( https://ift.tt/7o60cVa ) Keep as an “open source alerting CLI” and got some interesting feedback - mainly around UI, automation, and supporting more tools. We were VERY early back then, and we understood that although the current DX around creating alerts is not great, it's not that critical and developers don’t need another tool just for that. But we did find something else. While talking to developers and devops, we found that a lot of companies use many tools that generate alerts - from Cloudwatch, Prometheus, Grafana, and Datadog to tools such as Zabbix or Nagios. We definitely agree consolidation in the observability space is a real thing, but while talking to those companies we feel that there are still real use cases for having more than one tool (and for example, according to Grafana’s 2023 observability survey, 52% of the companies uses more than 6 observability tools https://ift.tt/FO16m5h ). So we that in mind, we rebuilt Keep with a simple mindset: (1) Integrate with every tool that triggers alerts - it can be either pushing alerts to Keep via webhooks or routing policies or Keep to pull alerts via the tools API. (2) Create a simple abstraction layer to run workflows on top of these alerts. (3) Maintain a great developer experience - open source, API-first, workflows as code and generally having a developer mindset while building Keep. During the time we rebuilt Keep, Datadog released their workflow automation tool ( https://ift.tt/zaZOyHm ) which led us to the understanding that's exactly what we solve - but for everyone who uses tools other than Datadog. A short demo of Keep with a simple use case: https://www.youtube.com/watch?v=FPMRCZM8ZYg You can try it yourself by signing into https://ift.tt/I8k9FXN Like always - we invite you to try Keep and we are eager to hear any feedback. https://ift.tt/q9T6L1P September 4, 2023 at 08:45PM
Show HN: Recognize license plates using fine-tuned yolov8, OCR and IP camera Hey, just a work related project I made, which could be open sourced :D If you're looking for an example on how to use/fine-tune yolov8, I feel like taking a look at this repo and reading the README could help you get up to speed (also linked some nice refs)! This is actually a full rewrite of a proprietary project I made (and documented on my site) like a year ago, will do some finishing touches (write blog post about it, mark the old version deprecated, record a tutorial on how to set it up on an Ubuntu server, etc, etc) in the following month, but felt like sharing it now, cuz I consider it done The only proprietary part is the client, which receives the images and does stuff with db (has to interact with internal APIs, so there's no reason to make it oss anyways). Also, the client contains only the business logic, all of the fun ai/web server stuff is fully open under AGPL-3.0 (and an example client without the business logic is available ... in rust btw xdd). https://ift.tt/D5ZsiKV September 5, 2023 at 01:26AM
Show HN: Rapidgzip – Truly Parallel Gzip Decompression with 10 GB/s I have posted a much earlier version of this over a year ago [0]. Since then a lot has changed. Obviously, the name has changed. This happened for the paper publication [1]. I have also optimized the speed, integrated ISA-L for special cases, limited the compression-ratio-dependent maximum memory consumption, and finally added parallelized CRC32 computation, which adds ~5% overhead no matter the number of cores used. At this point, I am leaning towards calling it production-ready although there are still many ideas for improvements. Redoing the benchmarks of the older Show HN, would look like this: time pigz -d -c 4GiB-base64.gz | wc -c # real ~13.4 s -> ~320 MB/s time rapidgzip -d -c 4GiB-base64.gz | wc -c # real ~1.26 s -> ~3.4 GB/s However, at this point, the piping itself becomes a problem. Rapidgzip is actually slightly faster than cat when comparing the piped bandwidth! E.g., compare these additional benchmarks: time cat 4GiB-base64.gz | wc -c # real ~1.06 s -> ~3.1 GB/s time fcat 4GiB-base64.gz | wc -c # real ~0.41 s -> ~8.0 GB/s time rapidgzip -o /dev/null -d 4GiB-base64.gz # real ~0.68 s -> ~6.5 GB/s fcat is an alternative cat implementation that uses vmsplice to speed up piping. According to the ReadMe it currently is broken, but it works fine on my system and piping it to md5sum yields consistent results [2]. So, at this point, I/O and actually also allocations have become a limiting factor and if you want full speed, you would have to interface with the rapidgzip library interface directly (in C++ or via the Python bindings) and process the decompressed data in memory. The project ReadMe contains further benchmarks with Silesia and FASTQ data and scaling up to 128 cores, for which rapidgzip achieves 12 GB/s for Silesia and 24 GB/s when an index has been created with --export-index and is used with --import-index. It can also be tested with ratarmount 0.14.0, which now uses rapidgzip as a backend by default for .gz and .tar.gz files [3].

Show HN: FeedsBot – A Meower bot that posts RSS feed updates to groupchats Hi, HN! I made this awhile back as a Meower[1] bot that posts RSS feed updates to groupchats, and reads RSS feeds, powered by Extractus' Feed Extractor[2][3]. My friend's groupchat uses this bot to post updates to his blog, and he says that it has been working out great. Looking forward to your feedback and suggestions!

It returns the relevant static content via HTTPS, enabling users to access decentralized networks with zero configuration on modern browsers. At the same time, we provide global CDN acceleration, striving to enhance the availability of decentralized content. https://bit.site/ September 2, 2023 at 09:00PM
Show HN: Modular Diffusion – A modular Python library for diffusion models Hello everyone! I've been working on this project for a few months as part of my thesis in Machine Learning. It's meant to be a library that provides an easy-to-use but flexible API to design and train Diffusion Models. I decided to make it because I wanted to quickly prototype a Diffusion Model but there were no good tools to do it with. I think it really can help people prototype their own Diffusion Models a lot faster and only in a few lines of code. The base idea is to have a Model class that takes different modules corresponding to the different aspects of the Diffusion Model process (noise schedule, noise type, denoising network, loss function, guidance, etc.) and allow the user to mix and match different modules to achieve different results. The library ships with a bunch of prebuilt modules and the plan is to add many more. I also made it super easy to implement your own modules, you just need to extend from one of the base classes available. Contrary to HuggingFace Diffusers, this library is focused on designing and training your own Diffusion Models rather than finetuning pretrained ones (although this is possible). I would really appreciate your feedback. https://ift.tt/xcAGI3p September 2, 2023 at 07:46PM
Show HN: Mini VI mode update of Aih for talking to AI models in terminal Hi! We have a milestone update that introduces a mini VI mode for editing the inspirational quests to AI models by just type .v, then you have hjkl, wbyd... and :ai to send question, :q cancel it. As a thought2source tool, we believe that the next generation of user interface would be LUI which stands for Language User Interface. With this insight we think that VI mode is a wonderful tool for editing the representation of the profound thought--our languages's writing form besides the living voice. Enjoy and welcome feedback:) https://ift.tt/Ia0Yk5W September 2, 2023 at 09:02PM
Show HN: XRss: An RSS Reader and web stack demo powered by Htmx XRss is a simple RSS reader web app built to showcase xtemplate, a new web development tool based on Go's html/template and Caddy server. The entire site UI for XRss comes from a single HTML template file . This index.html includes everything from SQL queries and route definitions and handlers to htmx state transition attributes and tailwindcss classes, and developing it requires zero build steps (amortized). Check out the source which manages to be at once banal and gnarly: https://ift.tt/HDibwYh... xtemplate preloads the whole template structure into memory and builds the router at startup, so responses to matching requests are rendered after a single lookup. Combined with direct queries to sqlite makes for a very snappy experience typically responding in less than 5ms. (Fingers crossed.) There are various places where XRss could be improved (PRs welcome!), but it already delivers on its purpose of demonstrating the plausibility of xtemplate. See the xtemplate readme for an overview of what you can do with it. I think of it as 'PHP but the syntax looks like Go templates'. https://ift.tt/YMwWDi0 Let me know what you think! Does remaking PHP from scratch out of Go templates make me a lunatic? (yes) Is it a good idea anyway? (yes) What kind of web application do you think would be a good fit for a platform like this? https://ift.tt/dPwKCv6 September 2, 2023 at 08:32PM

Show HN: Merge – Connect Google Wear OS to Apple iOS TLDR: Wear OS app for Samsung Galaxy Watches and Google Pixel Watches to connect them with iPhones, after Samsung and Google ditched iOS support back in 2021. Hi all! I recently switched to an iPhone and became frustrated when my Galaxy Watch was rendered useless, due to Google's and Samsung's decision to cut off iPhones from Wear OS back in 2021. I then started a project to create an alternative integration. I launched it 3 weeks ago as a Google Play app for Wear OS watches, most prominently for the Samsung Galaxy Watch and Google Pixel Watch. With this app, these watches can now connect to iPhones to control notifications and take phone calls. The response has been fantastic so far, with nearly 1k downloads and a steady growth rate. Should the demand continue to rise, I intend to expand the integration with additional features. I'd love to hear your thoughts and feedback, and answer any questions you might have. Thanks for your support! -- Merge is also on ProductHunt today: https://ift.tt/ldmMPpV... https://www.merge.watch September 1, 2023 at 05:39PM
Show HN: Squabblr – A Twitter/Reddit hybrid platform Hey guys, I made a post about this about a week ago and was told to create a Show HN post. So here we are! Squabblr is a hybrid that takes Twitter style posting and combines it with Reddit style commenting. It came up from a personal want where I liked using Twitter to see what people I'm interested in are up to, but found that the reply system left a lot to be desired. It's very hard to have or follow conversations with their UI. While Reddit provided a great commenting system but didn't support following people very well (or had much usage of it at all). So I decided to create Squabblr. You can "tweet" random blurbs or have in-depth conversations in a single unified platform. You can follow people, and you can also have Reddit style communities for whatever niche subject you find interest in. If you find any interest in it, check it out here! https://squabblr.com Tech stack: - Laravel - Vue.js - MySQL - DigitalOcean Appreciate your time! https://squabblr.co August 31, 2023 at 11:56PM
