Show HN: Stargazers Reloaded – LLM-Powered Analyses of Your GitHub Community https://ift.tt/EdYtGHb

Show HN: Stargazers Reloaded – LLM-Powered Analyses of Your GitHub Community Hey friends! We have built an app for getting insights about your favorite GitHub community using large language models. The app uses LLMs to analyze the GitHub profiles of users who have starred the repository, capturing key details like the topics they are interested in. It takes screenshots of the stargazer's GitHub webpage, extracts text using an OCR model, and extracts insights embedded in the extracted text using LLMs. This app is inspired by the “original” Stargazers app written by Spencer Kimball (CEO of CockroachDB). While the original app exclusively used the GitHub API, this LLM-powered app built using EvaDB additionally extracts insights from unstructured data obtained from the stargazers’ webpages. Our analysis of the fast-growing GPT4All community showed that the majority of the stargazers are proficient in Python and JavaScript, and 43% of them are interested in Web Development. Web developers love open-source LLMs! We found that directly using GPT-4 to generate the “golden” table is super expensive — costing $60 to process the information of 1000 stargazers. To maintain accuracy while also reducing cost, we set up an LLM model cascade in a SQL query, running GPT-3.5 before GPT-4, that lowers the cost to $5.5 for analyzing 1000 GitHub stargazers. We’ve been working on this app for a month now and are excited to open source it today :) Some useful links: * Blog Post - https://ift.tt/qZv93Sa... * GitHub Repository - https://ift.tt/JyVl8Hi * EvaDB - https://ift.tt/mOdkgYB Please let us know what you think!

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/L91f8qA September 30, 2023 at 12:41AM

Show HN: Ultra-Realistic Generative Fill with AI and 3D https://ift.tt/3nDsuGe

Show HN: Ultra-Realistic 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/9kmH8Ot September 29, 2023 at 03:41AM

Show HN: Launching a new home-grown embedding LLM for RAG https://ift.tt/karH9lT

Show HN: Launching a new home-grown embedding LLM for RAG Hi HN! Vectara is a "batteries included" retrieval augmented generation platform. You can upload your rich text documents like PDFs, HTML pages, word docs, etc, or semi-structured JSON and Vectara handles the text and metadata extraction, segmentation, vector embedding, and vector storage, and keyword storage. You can ask a question or perform a search in the UI or via our APIs and Vectara will automatically handle the vectorization, structured metadata filtering, vector+keyword retrieval, hybrid blending, and generative summarization of the results. We're focusing on building and operationalizing the complex infrastructure for vector storage, hybrid retrieval, and generative summarization so you can use fairly high-level APIs and focus on building your own applications. We know that retrieval accuracy is incredibly important for RAG: garbage in, garbage out. We've seen a lot of projects not spend enough time on really getting the retrieval model right and wasting a lot of time/money with poor outcomes. We've spent about the past 6 months working on a new embedding model named Boomerang and just released it on the Vectara platform. We've run it through standard evaluations like BEIR (though we know many models over-fit against BEIR) as well as multi-domain evaluations. We've published the details of our tests for those that really want to dive in, but the TL;DR is that Boomerang beats most/all publicly available models in many/most situations and is particularly strong at cross-lingual and multi-domain tests. We'd love any and all feedback! https://ift.tt/zi7C5lv September 28, 2023 at 10:06PM

Show HN: Use ChatGPT with Apple Shortcuts https://ift.tt/xAL9HFk

Show HN: Use ChatGPT with Apple Shortcuts This project was born from my passion for every Apple product and the entire ecosystem, along with the power of ChatGPT. I was tired of copy-pasting and switching between apps on my Mac or iPhone, so I had this crazy idea to bring ChatGPT into every app that I use. This was possible only with the Apple Shortcuts app. Very few people know about its power and potential, so I took this chance and built COPILOT. https://meetcopilot.app But I also loved the idea of AI agents using various tools so much that I leveraged OpenAI's function-calling feature to accomplish that. Now, no matter what app I am using on my iPhone or Mac, the selected text or the current webpage from Safari will be passed automatically to COPILOT. Then I just ask it whatever I need and watch until it reaches the goal autonomously. There was also another problem with ChatGPT - the knowledge cutoff. So I also integrated Google search and web scraping into it. Now, whenever my request needs real-time information, like what is the latest version of macOS, it will use these tools to gather the data and then give me the correct response. Being an app built with Apple Shortcuts, all its "code", called actions, is actually open-source. I'm selling a Premium version of it to earn some revenue for my time. I would love to hear all your thoughts on it! Thank you so much! https://ift.tt/SOjBs2A September 27, 2023 at 03:37PM

Show HN: Using LLMs and Embeddings to classify application errors https://ift.tt/c2rMplF

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: XRain – Explore rainfall statistics around the world Last year I launched a website that allow people to see rainfall statistics that are based on satellite data. Historical rainfall information usually comes from rain gauges, and while these are fantastic there are many parts of the world that don't have many long term gauges, or where that data is hard to access. Satellite data can be an invaluable source of information for those data-scarce areas. The business model is to sell "extreme precipitation" data that can be used for flood modelling. Unfortunately, after a year I still haven't made a single sale. I've tried various ways of advertising, mainly via messaging people on LinkedIn who would actually have a use for it. I'm still proud of what I've built, even if it's a flop! Fun feature: jump to a completely random part of the world by clicking the "Random" button.

Show HN: Unity like game editor running in pure WASM https://ift.tt/BwrSK4q

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/svwYDyL... 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/JeHjPBN https://ift.tt/bFog6lz September 27, 2023 at 12:58AM

Show HN: MyGPT a toy LLM which can be trained on Project Gutenberg and dad jokes https://ift.tt/ZedohUO

Show HN: MyGPT a toy LLM which can be trained on Project Gutenberg and dad jokes My puny version of ChatGPT. This was based on the excellent LLM lecture series by Andrej Karpathy: https://www.youtube.com/watch?v=kCc8FmEb1nY The main points of differentiation are that my version is token-based (tiktoken) with code to load up multiple text files as a trining set. Plus, it has a minimal server which is a drop-in replacement for the OpenAI REST API. So you can train the default tiny 15M parameter model, and use that in your projects instead of ChatGPT. I trained it on 20Mb of Project Gutenberg encyclopaedias, then fine-tuned it on 120 dad jokes, to get a Q: A: prompt format. This model + training set is so small that the results are basically a joke; it's for entertainment purposes only. The code is also very rough, and the server only has the minimum functionality filled in. I embodied this model in my talking LLM-driven hexapod robot, and it could give very silly answers to spoken questions. https://ift.tt/iAm9olH September 26, 2023 at 09:51PM

Show HN: Basketball Play Designer https://ift.tt/HoOAyQr

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/9j4fw7Q September 24, 2023 at 02:36AM

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/YipcTvr https://ift.tt/D71qVhu September 24, 2023 at 12:21AM

Show HN: Vanya – FHIR data viewer for developers working with healthcare APIs https://ift.tt/Lj2iWzs

Show HN: Vanya – FHIR data viewer for developers working with healthcare APIs FHIR => Fast Healthcare Interoperability Resources I began working with healthcare data using FHIR APIs a few years ago, and was immediately struck by the lack of useful tools for developers. Everyone was using Postman. Development and testing was slooooow. QA was a nightmare. Sprint and business demos involved running Postman queries and browsing JSON results. Painful! So I built Vanya — an app for developers in the style of a database client, but with extras for FHIR. It’s a quick viewer that shows the most recently updated resources, and allows the developer to drill down into connected resources (Patient, Procedure, Medication). The raw JSON is still there to see, but the more common fields are presented in a results grid. The backend is C# / .NET. The UI is Electron, with builds for Windows and Mac. (The Mac was a real pain to build and notarize — a post here on HN a few weeks ago helped with that.) It’s being used right now by the teams I’m working with on a big real world project, and despite its lack of features (alpha version) is delivering real value and saving devs a lot of time. I’d love any feedback from developers who work with FHIR or in the healthcare space. And anyone who’s able to test out the Mac versions.

Show HN: I rewrote the 1990's LambdaMOO server from scratch https://ift.tt/mdLHYNb

Show HN: I rewrote the 1990's LambdaMOO server from scratch I got my start on the Internet in the very early 90s playing with, authoring in, and programming on LambdaMOO ( https://ift.tt/YtFyXKI ) and similar systems. Shared virtual social spaces, with a persistent object oriented authoring / scripting language. They can be classified as MUDs (depending on who you talk to) but the focus is social, creative / authoring, and shared programming not RPG gaming. I've always wanted to see this kind of thing modernized and further developed. Over the last 25 years or so I've worked on similar but novel & improved things, but never finished. So I decided to just re-implement LambdaMOO and use that as a base, instead and keep compatibility as a goal, but build it out on a more modern foundation that takes advantage of multiple core machines, newer network protocols, newer connectivity methods, uses MVCC transactions for the shared database etc. LambdaMOO is a somewhat extensive system in that it is composed of compiler, a virtual machine, an object database, user permissions system, network runtime. In some ways it's kind of like a shared, text-based Smalltalk image/runtime... So quite a bit to implement and get right before it all works together. The big challenge throughout has been slavishly maintaining backwards compatibility so existing "cores" (databases) work. It's not done, but it's darn close. Would like for people who are into this kind of thing to check it out, and maybe even help. Many of the technical aspects here are still provisional, but this is the start. Constructive assistance welcome. (Yes, it's a rewrite in Rust, but that's not really the point, even though that's a cliche that's fun.) https://ift.tt/GItpJ4A September 23, 2023 at 10:56PM

Show HN: Movie Guess – A AI movie title guessing game While i was playing dark stories i got the idea of a game that an AI would think of a movie and the user would have to ask questions. The trick is that the AI only answers yes or no and the user has to guess the movie name, asking things like "is the movie a comedy" or "it's about a family trip" So that is it, hope you enjoy the game.

Show HN: Tinyfeed – CLI to generate static webpage from a collection of feeds https://ift.tt/iKfjOtY

Show HN: Tinyfeed – CLI to generate static webpage from a collection of feeds This project started because I wanted to consume my RSS/Atoms feeds the same way I consume news on HN: a lightweight webpage with a minimalist user interface where I can comfortably browse interesting links. I didn't like existing solutions for feeds reader. Many of them seemed overly complex, most of them require a database and don't event support sqlite. For a simple feed reader, it felt overkill. What I wanted was an easy setup that didn't rely on external databases or configurations. My solution was to build a small CLI tool that print an HTML page from a list of feed URLs. I can just set it up in Cron, point NGINX to the generate HTML file and that's it, I have a lovely webpage with my feeds. This was my first real project in Go and I'm still learning so I'm eager to receive feedback on the code.

Show HN: Corgi – on-demand, 1-on-1 tutoring https://ift.tt/WmYx9JE

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/bwEp1W3... ). 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/zOqynTp September 22, 2023 at 09:23AM

Show HN: My Single-File Python Script I Used to Replace Splunk in My Startup https://ift.tt/wYMkGZ9

Show HN: My Single-File Python Script I Used to Replace Splunk in My Startup My immediate reaction to today's news that Splunk was being acquired was to comment in the HN discussion for that story: "I hated Splunk so much that I spent a couple days a few months ago writing a single 1200 line python script that does absolutely everything I need in terms of automatic log collection, ingestion, and analysis from a fleet of cloud instances. It pulls in all the log lines, enriches them with useful metadata like the IP address of the instance, the machine name, the log source, the datetime, etc. and stores it all in SQlite, which it then exposes to a very convenient web interface using Datasette. I put it in a cronjob and it's infinitely better (at least for my purposes) than Splunk, which is just a total nightmare to use, and can be customized super easily and quickly. My coworkers all prefer it to Splunk as well. And oh yeah, it's totally free instead of costing my company thousands of dollars a year! If I owned CSCO stock I would sell it-- this deal shows incredibly bad judgment." I had been meaning to clean it up a bit and open-source it but never got around to it. However, someone asked today in response to my comment if I had released it, so I figured now would be a good time to go through it and clean it up, move the constants to an .env file, and create a README. This code is obviously tailored to my own requirements for my project, but if you know Python, it's extremely straightforward to customize it for your own logs (plus, some of the logs are generic, like systemd logs). And I included the actual sample log files from my project that correspond to the parsing functions in the code, so you can easily reason by analogy to adapt it to your own log files. As many people pointed out in responses to my comment, this is obviously not a real replacement for Splunk for enterprise users who are ingesting terabytes a day from thousands of machines and hundreds of sources. If it were, hopefully someone would be paying me $28 billion for it instead of me giving it away for free! But if you don't have a huge number of machines and really hate using Splunk while wasting thousands of dollars, this might be for you. https://ift.tt/6B4Pq5S September 21, 2023 at 11:26PM

Show HN: A website that gives voice to unfulfilled customer needs https://ift.tt/DxAiy6L

Show HN: A website that gives voice to unfulfilled customer needs How does it work? You just write a short title of what you want like “24/7 cafe in my town”, a short description why you need it - “I like to work late, don’t like to work at home and all coffee places close at 9” and how much you would pay per visit. If many people subscribe to your idea, hopefully someone will see it and open that coffee shop. You can also see what others want and maybe get inspired. Or you can just use the website to track your ideas. What problems am I trying to solve? 1. Many startups fail because they build something that customers do not want 2. Customers do not get services they need because their voices are not heard This project attempts to solve the two problems by giving the voice to the customers and a platform for startup founders to research customer demand backed product ideas. The project is at its earliest stage, so any feedback, bug reports and feature requests are welcome! https://ift.tt/vZEUM8k September 21, 2023 at 06:47AM

Show HN: Booklet – Async forums as an alternative to chat I built Booklet to solve the problem of too many chat messages at work. Booklet updates classic internet forums and email groups to have a modern UI and high polish. It organizes communications into threads, and summarizes activities into a neat email newsletter - so members can stay updated without having to stay logged in. The async format promotes deeper discussions, while also increasing engagement by making conversations easy to follow. My goal is to make communications more asynchronous - so that I can get back to work, instead of slacking all day. Most early communities have been hobby groups, but my goal is to mature Booklet into a tool that sits alongside Slack in companies. Try it out, and let me know what you think! https://ift.tt/qDiyPs6 September 20, 2023 at 11:02PM

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. If there are other techniques that have worked out for you, do let me know, I will try to incorporate those :) Would love honest feedback on this so that I can make this more useful to others and to myself. Looking forward to your feedback, thanks in advance :) https://focusdoro.com September 19, 2023 at 09:43PM

Show HN: Hydra - Open-Source Columnar Postgres https://ift.tt/EXKLFbf

Show HN: Hydra - Open-Source Columnar Postgres hi hn, hydra ceo here hydra is an open-source extension that adds columnar tables to Postgres for efficient analytical reporting. With Hydra, you can analyze billions of rows instantly without changing code. demo video (5 min): https://youtu.be/1yzxgb0Oyrw github repo: https://ift.tt/wtjHT4o For 1.0 GA release, aggregate queries are over *60% faster* than Hydra beta due to aggregate vectorization. Spatial indexes (gin, gist, spgist, and rum indexes) and pg_hint_plan are now enabled for performance optimization. postgres is great, but aggregates can take minutes to hours to return results on large data sets. long-running analytical queries hog database resources and degrade performance. use hydra to run much faster analytics on postgres without changing code. for testing, try the hydra free tier to create a column postgres instance on the cloud. https://ift.tt/vYsT6q3 https://ift.tt/awK78z5 September 19, 2023 at 11:05PM

Show HN: Dittofeed – 1-Click deploy, self-host Mailchimp alternative https://ift.tt/BA8m2tD

Show HN: Dittofeed – 1-Click deploy, self-host Mailchimp alternative Hi HN, we've released Dittofeed v0.4.0, a significant update primarily focused on facilitating self-hosting. Dittofeed is an open source (MIT licensed) alternative to platforms like customer.io, mailchimp, klaviyo, iterable etc. Self-hosting is particularly useful if you: - Want to evaluate Dittofeed without a long-term commitment - Prefer fixed, non-volume based pricing models - Aim to keep all personally identifiable information within your own infrastructure In this version, we introduced 'Dittofeed Lite,' which merges the dashboard, API, and worker services, simplifying deployment, along with providing an easy auth setup. We've also configured a 1-Click Render deployment. The Render setup comes at a fixed cost of $39/month. However, by using alternative hosting solutions for the Postgres and ClickHouse instances (neon, clickhouse cloud), the monthly costs can be reduced to under $20. We personally feel that there’s a big problem with how existing platforms handle pricing, charging insanely high prices with low contact limits, while restricting access to really basic table stakes features. Excited to share this work, and hear your thoughts and feedback!

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 02:51AM

Show HN: A murder mystery game built on an open-source gen-AI agent framework https://ift.tt/9WeF5wZ

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: HyperDX – open-source dev-friendly Datadog alternative https://ift.tt/y4nSxcW

Show HN: HyperDX – open-source dev-friendly Datadog alternative Hi HN, Mike and Warren here! We've been building HyperDX (hyperdx.io). HyperDX allows you to easily search and correlate logs, traces, metrics (alpha), and session replays all in one place. For example, if a user reports a bug “this button doesn't work," an engineer can play back what the user was doing in their browser and trace API calls back to the backend logs for that specific request, all from a single view. Github Repo: https://ift.tt/EMpAwxk Coming from an observability nerd background, with Warren being SRE #1 at his last startup and me previously leading dev experience at LogDNA/Mezmo, we knew there were gaps in the existing tools we were used to using. Our previous stack of tools like Bugsnag, LogRocket, and Cloudwatch required us to switch between different tools, correlate timestamps (UTC? local?), and manually cross-check IDs to piece together what was actually happening. This often made meant small issues required hours of frustration to root cause. Other tools like Datadog or New Relic come with high price tags - when estimating costs for Datadog in the past, we found that our Datadog bill would exceed our AWS bill! Other teams have had to adjust their infrastructure just to appease the Datadog pricing model. To build HyperDX, we've centralized all the telemetry in one place by leveraging OpenTelemetry (a CNCF project for standardizing/collecting telemetry) to pull and correlate logs, metrics, traces, and replays. In-app, we can correlate your logs/traces together in one panel by joining everything automatically via trace ids and session ids, so you can go from log <> trace <> replay in the same panel. To keep costs low, we store everything in Clickhouse (w/ S3 backing) to make it extremely affordable to store large amounts of data (compared to Elasticsearch) while still being able to query it efficiently (compared to services like Cloudwatch or Loki), in large part thanks to Clickhouse's bloom filters + columnar layout. On top of that, we've focused on providing a smooth developer experience (the DX in HyperDX!). This includes features like native parsing of JSON logs, full-text search on any log or trace, 2-click alert creation, and SDKs that help you get started with OpenTelemetry faster than the default OpenTelemetry SDKs. I'm excited to share what we've been working with you all and would love to hear your feedback and opinions!

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 10:16PM

Show HN: Product Review Summarizer https://ift.tt/bQj84Fk

Show HN: Product Review Summarizer I find it inefficient to read through the product reviews online. So i wrote up this site. It works by pumping the reviews into an llm and giving a few bullet points for negative and positive. For now it works only with amazon. I mostly did this to learn about web technologies. This is my first time not using managed hosting but configuring a ubuntu vps from scratch. I would appreciate technical feedback. Disclaimer: The "Buy on Amazon" button adds an affiliate to the original link. Oh I also read now that amazon is rolling out some "AI" Summary, but its not available where i live yet. So my site might not be needed for long. https://ift.tt/ugRQAYG September 17, 2023 at 08:47PM

Show HN: Applin – define mobile UI in server code https://ift.tt/BT9QgJP

Show HN: Applin – define mobile UI in server code Hi HN, I'm a backend engineer who made an app and didn’t like the tools. Then I made the thing I needed: a mobile app toolkit for backend engineers. I'm calling it Applin™. :) https://www.applin.dev/ How it works: You make an HTTP server that returns JSON objects that define page content. Then you make a mobile app that calls the server and renders the pages using native widgets. Applin is the server and client libraries that make this easy. Server libraries: Currently there's Rails https://ift.tt/wOEhS61 and https://ift.tt/ck34Mpq . Which languages shall I add next? Client libraries: Currently there's iOS https://ift.tt/vE6upDY . Which platform shall I add next? They say, if you're not embarrassed by the quality, then you're launching too late. Applin is usable and not yet pretty and not yet comprehensive. I need customer feedback on priority and requirements. To try it out right away, use https://ift.tt/3X5hH4T and tap the rails-demo link. The hardest part of this project was making the client update the page without losing keyboard focus and scrolling to the top. To do that, the code must pick the correct existing widgets for each new version of the widget tree. The current (working) version performs five passes over the widget tree: first picking focused widgets and their ancestors, then focus-able widgets, then other stateful widgets, then widgets with matching attributes (label, URL, etc.), and finally former siblings of the correct type. Then it creates any new widgets. Now that it has widgets for the new tree, the code updates the widget tree without removing any sub-widget that will be added again. This prevents losing keyboard focus and prevents resetting scroll positions. Here's the code: https://ift.tt/rcNZoW5 Please try out Applin, use it at your company (buy a license), and let me know what features to build first! Post a comment here, add a GitHub issue, or email me at michael@leonhardllc.com . To get updates, join https://ift.tt/jtE61LO . Thanks for reading! :) --Michael September 16, 2023 at 01:00AM

Show HN: Nue – A React/Vue/Vite/Astro Alternative https://ift.tt/9LlgTbo

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/3UaxEqe — 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/xJ8aXk2 — 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 06:11PM

Show HN: A vector database with semantic SQL-like filtering https://ift.tt/L48gJEI

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/jKWyd3L ! 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/bGzk7D3 September 15, 2023 at 01:04AM

Show HN: Ever Been Rated by an AI Date? Try Dating Playground and Get Feedback Hey HackerNews folks! I first launched DatingAI.pro to help people improve their dating profiles, get reply suggestions, etc but to that I got feedback where people pointed out that someone could just impersonate their entire profile which made sense and I thought what if I could actually help people really get better at texting or conversations by giving them feedback and letting them improve via suggestions. I understand a human date can't be replaced but certainly we could help to an extent. NOTE - THIS IS NOT AN AI GIRLFRIEND. This is how it works: 1. Swipe from profiles of the opposite gender and then you're matched with someone. 2. Start an engaging chat & earn or lose points based on your charm (or lack thereof). 3. Simultaneously get reply suggestions to navigate the conversation. 4. Receive a final verdict: Would they like to go out on a date with you? And the best part? Those points aren't just for bragging rights they can be redeemed them for other features in the tool. Think of it as a dating simulator with tangible rewards. Would love to know your thoughts https://datingai.pro September 14, 2023 at 10:02PM

Show HN: Lantern – a PostgreSQL vector database for building AI applications TL;DR Lantern is a PostgreSQL vector database extension for building AI applications. Install and use our extension here: https://ift.tt/YnIrgv6 We have the most complete feature set of all the PostgreSQL vector database extensions. ** Here’s what we support today ** - Creating an AI application end to end without leaving your database (example: https://ift.tt/mLuUN2S... ) - Embedding generation for popular use cases (CLIP model, Hugging Face models, custom model) - Interoperability with pgvector's data type, so anyone using pgvector can switch to Lantern - Parallel index creation capabilities -- Support for creating the index outside of the database and inside another instance allows you to create an index without interrupting database workflows. ** Here’s what’s coming soon ** - Cloud-hosted version of Lantern - Templates and guides for building applications for different industries - Tools for generating embeddings (support for third party model API's, more local models) - Support for version control and A/B test embeddings - Autotuned index type that will choose appropriate index creation parameters - 1 byte and 2 byte vector elements, and up to 8000 dimensional vectors support - Request a feature at support@lantern.dev ** Why we started Lantern today ** There's dozens of vector databases on the market, but no enterprise option built on top of PostgreSQL. We think it's super important to build on top of PostgreSQL - Developers know how to use PostgreSQL. - Companies already store their data on PostgreSQL. - Standalone vector databases have to rebuild all of what PostgreSQL has built for the past 30-years, including all of the optimizations on how to best store and access data. - Lantern is building the most performant vector database and the best suite of tools to help developers build AI applications. We want to help companies build useful applications using their unstructured and structured data. Looking forward to hearing your feedback! https://ift.tt/7k35nPX September 14, 2023 at 12:41AM

Show HN: Victor, a browser-optimized vector database written in Rust https://ift.tt/S2dKpNV

Show HN: Victor, a browser-optimized vector database written in Rust Hey HN, My friend Sam and I were bored one weekend, and wanted to make something self-contained but still useful. We ended up with Victor [0], a vector database designed to run in the browser. It’s written in Rust, which gives us access to things like super-fast and compact serialization and deserialization, but it’s compiled to WASM and uses web-sys to interact with the browser’s JS APIs to write the database contents to disk. We worked hard on designing it in a way that makes sense for the browser. It uses the private origin file system [1] and stores the vectors in a compact format (one byte per vector dimension). Since storage space is at a premium in the browser, we also provide built-in PCA to allow you to compress your vectors. It’s completely transparent to the user and automatically kicks in once a vector storage file exceeds 10mb. We’re trying to think of a better way to design this API, so let us know any ideas you have!

Show HN: Labor Day Fun Project, Find Reddit Comments to Promote Your Business For Labor Day I decided to play with OpenAI APIs and try to ship something (a prototype, a blog post, anything really). Whenever I launched a side project (e.g: https://ift.tt/fUbmo9p , https://ff.bitlet.org/ ) I realized how bad I am at marketing or even at mentioning my the project to friends/social. I noticed that most of the traffic we got was coming from reddit/HN comments we made where it was reasonable to mention the sideproject/business. Given that, I tried to use OpenAI APIs to do exactly that, given a business/project description, and a list of subreddits, monitor all comments and pick the ones where it makes sense to mention the business/project. While I had the project done in the labor day weekend, I decided to productionize it a bit (really just add a login system and a payment link to cover OpenAI costs) last weekend.

Show HN: Firefox addon to quarantine a tab to use offline with private data Introducing QuaranTab: Companion extension to quarantine tabs so you can safely use them offline with private data I find myself wanting to use online format parsers to quickly decode that production JWT or decode a base64 Authorization header but cannot trust these websites to not leak my information. I thought to myself if only I could cut-off network access to this site, use it offline, and then throw away all browsing data. So I created an extension just for that. It uses Firefox contextual identities API (Containers) to isolate browsing data and inter-tab communication. Once the site is fully loaded, I then inject bogus proxy settings for any requests leaving that container to effectively cut-off network access. And once I'm done, I simply delete the Container. Use Cases: * Parse a live JWT token * Convert a Base64 Authorization header * Hash a password * Parse a Protobuf message * Submit my name and birthdate to estimate my date of death Check out the MIT source code on GitHub [1] and install QuaranTab from the Firefox store [2]. If anyone is interested in a discussion, I'd love to chat about: 1. Any ideas on how we could implement this in Chromium? Using private window as a "Container"? 2. Can you come up with an exploit? I posted a 100usd bug bounty [3] if you find one! 3. Is there any way to prove an extension in the store was built from source in GitHub?

Obviously, running sequentially through a list of ports until I find one I have not already allocated does not perform very well.

Show HN: Monthly budgeting spreadsheet and ML expense categorisation Hello, I'd like to share the first version of an app I've built for myself to categorise my expenses. Key features: - *Google Sheets Integration:* The tool is based on the spreadsheet I've been using to track my expenses over the years. I've turned it into a template that is available on the website. - *Automated Expense Categorization:* Tired of manually categorising and annoyed by the limits of rules, I've hooked the sheet up with an ML model that works based on past categorisations of your expenses. I've had great results with it. The tool is simple and basic and lets you keep using your spreadsheet instead of moving stuff into proprietary apps. It's a first version, but it's working for me so I thought I'd share it to see if anyone else might find it useful. You can start by exploring the [demo]( https://ift.tt/8mMN9oi ) and get the Google Sheet Template to dive right in. https://ift.tt/FEtvD1w Looking forward to your feedback! https://ift.tt/FEtvD1w September 10, 2023 at 11:47AM

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/48KNqeQ September 9, 2023 at 11:56PM

Show HN: Which is faster? Puppeteer, Playwright or Selenium https://ift.tt/BYOATNo

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/j3tFkQJ September 9, 2023 at 06:24PM

Show HN: New AI Dataset Based on LibGen and Sci-Hub https://ift.tt/0OrncTm

Show HN: New AI Dataset Based on LibGen and Sci-Hub We recently began extracting the text layers of scholarly publications and books to include in our database. This encompasses sources such as scimag, libgen, and the latest zlib leaks. Our project, named the Standard Template Construct, also features a distributed search engine and incorporates various AI routines to handle the text corpus. Today we have releases our first dataset, STC230908. This dataset contains approximately 75,000 book texts, 1.3 million scholarly paper texts, and 24 million abstracts, including the years from 2021 to 2023. We're currently in the process of preparing the next version of the dataset, which will include an additional 300,000 books. How to Access Short Instructions: Install IPFS and launch it. pip3 install stc-geck && geck - documents More details: the dataset is released in IPFS and replicated to multiple nodes. It is in format of database for the search engine that we use in STC. GECK is the library that embeds this search engine and allows to stream all contained data in easy way.

Show HN: Find jobs at top AI startups https://ift.tt/7THNPlY

Show HN: Find jobs at top AI startups Hello HN, I am one of the creators of WorkInAI, and I'm excited to share our project with the community and gather valuable feedback. WorkInAI is a job aggregation platform for positions at leading AI startups. We have compiled over 350 job listings from more than 20 top AI startups, including companies like OpenAI, Anthropic, Cohere, and more. We created this platform in response to a friend's frustration with trying to find suitable AI startup roles in London. He used to check various company career pages frequently to see if any new opportunities had arisen -- so we built this to aggregate jobs in a single place. We're launching this MVP early to gather feedback, whether it's feature requests or suggestions for adding new startups to our list. We value your thoughts and input on our product and idea. Thanks! https://workinai.xyz/ September 8, 2023 at 11:21PM

Show HN: HackYourNews – AI summaries of the top HN stories https://ift.tt/ujm8i4V

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 Python with the excellent Microsoft Guidance [3] library to interface to OpenAI's API.

Show HN: Frcntl – community for fractional developers and designers https://ift.tt/d0zQ7Wf

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 09:56PM

Show HN: Curated custom search engine portal https://ift.tt/wop91rA

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/MHqdYr3 . Thanks for reading, lemme know what you think :D https://ift.tt/MHqdYr3 September 7, 2023 at 12:49PM

Show HN: uDSV.js – A faster CSV parser Hey folks! I know CSV parsers (especially in JS) aren't terribly exciting and someone writes a "better" one every week. 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). The benchmarks were a huge effort, but I think they are the most thorough to date, both in breadth and in depth, so hopefully you find them useful: https://ift.tt/ktpoXOy Let me know if you have specific concerns / questions / improvements :) cheers!

Show HN: Nix Snapshotter – Native understanding of Nix packages for containerd https://ift.tt/on0umsa

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/eopid92 https://ift.tt/eopid92 September 6, 2023 at 11:54PM

Show HN: Trellis – open-source Python framework to build DAG-based LLM workflows https://ift.tt/VTJOmXa

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/wYJOqB5... We'd love it if you tried hacking with it and give us any feedback you have! :) https://ift.tt/umj5f8d September 6, 2023 at 09:04AM

Show HN: Miko – an alternative to googling healthcare queries https://ift.tt/CR1dx7r

Show HN: Miko – an alternative to googling healthcare queries This is a personal experiment that uses AI to respond to healthcare queries. I was fed up of googling symptoms which provided no concrete advice. The only alternative was to fork out for a doctor's appointment that would last a few minutes. So I built a little tool that will hopefully augment people's interactions with their health. I have no interest in replacing the hospital or the need for a doctor. Miko is not flawless but it is a free, instant alternative to expensive healthcare. My hope is that users would try the advice Miko gives them but also visit their doctor if their symptoms persisted. Previously I built a one-stop shop for healthcare which sold services at discounted prices but it is just an interesting side project. I have investigated ways of incorporating GPT and other models into healthcare since last year. I used bubble.io for the web app because of its convenience. https://ift.tt/2PRQoUr September 6, 2023 at 03:23AM

Show HN: Open source Postman alternative with type safety https://ift.tt/6tKX4xW

Show HN: Open source Postman alternative with type safety Hello! This is Jeane and Samuel and we’re building RecipeUI. RecipeUI is an open source Postman alternative that uses TypeScript to statically type and autocomplete requests. We built this because current API tools don’t deal with the fact that some APIs are just painful to work with. For us, it’s usually error after error as we try to figure out how to properly form the first request. We recorded a demo to show you how TypeScript helps us autocomplete a request correctly. https://youtu.be/O_Mly_p-g5s How does our platform improve the developer experience? The analogy is similar to using a statically typed language vs dynamically typed. Most API tools are dynamically typed. You’re guessing the params and relying on the request to magically work at runtime, only for you to go back to stack overflow or the docs when it doesn’t. We take the approach of defining parameters and the schema first. When you add a new parameter, you need to mention upfront if it’s required and what type it is (integer, string, boolean). While this can be painful in the beginning, it will save you and anyone you share this with the hassle of understanding how this API works. Our app is cross-platform on web and desktop. Our desktop app is <20mb and built on top of Rust with Tauri, NextJS, and Supabase. We open source our code because we want to be transparent about how API requests and secrets are handled (all local IndexDB). I built the first version of this at Robinhood when my colleagues were sharing bash scripts and internal APIs on slack to test things. I wanted to make it easier for anyone to use an API quickly and made use of our OpenAPI specs to generate a nice autocomplete API tool. Soon after, the Options team, then the Crypto team, and then the whole eng org at Robinhood adopted this tool! Try it out at recipeui.com! Please star us on GitHub if you like the product https://github.com/RecipeUI/RecipeUI . https://recipeui.com/ September 5, 2023 at 10:33PM

Show HN: Keep – GitHub Actions for your monitoring tools https://ift.tt/2lc1VCd

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/xukVOa1 ) 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/LWAuorv ). 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/DA9pq2w ) 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/W2Fwhyb Like always - we invite you to try Keep and we are eager to hear any feedback. https://ift.tt/EGujZoN September 4, 2023 at 10:15PM

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/jgiqSJE September 5, 2023 at 02:56AM
