Show HN: RSS Filter Sometimes it's hard to keep up with multiple RSS feeds, and would be great to get some help filtering out the least relevant part of it. RSS filter is a side project that I created for myself to act as an RSS feed articles recommendation system, but self-hosted. It has a Python backend that is able to “proxy" your existing RSS feeds and after learning a bit about your interests, starts recommending similar articles and filtering out the rest. While, of course, always including some random articles for discovery. It uses LLM embeddings and machine learning to recommend similar articles. Embedding models allow for a new era of recommendation systems, where a large user base is not required, since allowing for self-hosting. Feel free to try it on my server or self-host it yourself. All feedback and contributions are welcome. https://ift.tt/VY4HnT9 April 1, 2024 at 03:18AM

Show HN: Turn your work into a multiplayer adventure I was on the eternal quest of searching for a properly gamified productivity app that keeps me motivated throughout the day and in the long term. After a few months of a fruitless search, I made up my mind and decided to build it myself! I've since launched FocuMon a little over a month ago. Quite a few early users told me it has helped them stay focused, so I'm excited to share it on HN for ya'll to try it out and let me know how I can make it better! FocuMon is like an idle Pokémon game where you can collect, level up, and evolve cute monsters by being productive! It puts a reward layer on top of your work which helps to give you an initial boost to get into focus; it then gets out of your way once you are in the flow :) I'm actively developing more features & game modes for FocuMon. It is also a multiplayer-first app where you can adventure together with people from all over the world! Cheers and thanks for you

Show HN: FaceLandmarks – ARKit Face Mesh Vertex Tool Hey everyone. FaceLandmarks.com is a little project I put together last weekend, while working with Apple's ARKit for iOS face tracking. For those not familiar, since iOS 11 and A9 processor was released, all iPhones (i.e. iPhone 6s and newer) support augmented reality capabilities. When tracking a face using the front camera and the ARKit framework, a face mesh is generated using exactly 1,220 vertices that are mapped to specific points on the face. These vertices are accessible through ARFaceGeometry, ARFaceAnchor, and ARSCNFaceGeometry within ARKit, and provide a foundation for developers to do facial tracking for common use cases like: social media filters, accessibility, avatars, virtual try on, etc. While the ARKit's tech is impressive and has a smooth DX, the most frustrating part for me was identifying the vertex indexes for specific points on the face mesh model. Apple does not provide a comprehensive mapping of thes

Show HN: Dealwise, an investment bank that scales with AI instead of analysts Hi hacker news, We’re a former PM and software engineer from Robinhood who decide to start an investment bank for startups. In 2023, we had just shut down our previous YC-backed startup Psychic ( https://ift.tt/G1piIVB ). We were one of many startups building generative AI infrastructure long before it had become apparent what the applications were going to be, and it turns out the bet we made was wrong. This might sound familiar to anyone who’s been through the web3 hype cycle, but it was a big learning for us. Around the same time, we noticed a lot of interest in M&A activity from our founder friends, and informally advised one of our batchmates in the sale of his startup. We started learning about what it takes to get deals done, and that’s when we realized there was a massive gap in advisory services for founders who want to step off the venture path (or were never on it in the first place) that exist

Show HN: GritQL, a Rust CLI for rewriting source code Hi everyone! I’m excited to open source GritQL, a Rust CLI for searching and transforming source code. GritQL comes from my experiences with conducting large scale refactors and migrations. Usually, I would start exploring a codebase with grep. This is easy to start with, but most migrations end up accumulating additional requirements like ensuring the right packages are imported and excluding cases which don’t have a viable migration path. Eventually, to build a complex migration, I usually ended up having to write a full codemod program with a tool like jscodeshift. This comes with its own problems: - Most of the exploratory work has to be abandoned as you figure out how to represent your original regex search as an AST. - Reading/writing a codemod requires mentally translating from AST names back to what source code actually looks like. - Performance is often an afterthought, so iterating on a large codemod can be painfully slow.

Show HN: Reactive Jupyter- reactive execution of Python in VSCode Hi HN I’ve developed an experimental VSCode extension to keep a Python Kernel in sync with a Python file. (Reactive execution) The extension uses Static Code Analysis to infer dependencies between lines of code. When you modify a line in a file, it will be marked as Stale together with all the lines that depend on it. You can Sync the state with Ctrl+Shift+Enter. In this way, you are always in control. See the Readme for a detailed demo. —------------- The primary limitation of this extension is that it currently relies on Static Code Analysis, which can only do so much. Again, see the Readme for a discussion. This extension is also in PREVIEW. I’m sure there are bugs around. Both in the Static Code Analysis of more obscure Python idioms (even though it’s pretty robust for the simple ones), and in the interaction with the VsCode APIs (lots of edge cases there). —------------- The intended use cases are machine learning,

We want to share a tool we’re working on to detect fake and real images: https://ift.tt/W2FOR35 . The UI is bare-bones but you’ll get the idea. Drag or upload an image and our tool will display the probabilities with which it thinks that the image might be AI-generated or not. If you want, you can click “No, it’s AI” to confirm that the image was AI-generated, or “No, it’s real” to confirm that the image was not AI-generated. Why we’re working on this: as AI-generated images continue to blur the line between real and artificial and their adoption and quality rises, so too does the risk for fraud and misinformation. Not being able to trust what you see online threatens whatever level of "realness" or authenticity online material has.

Show HN: Website for creating self-signed certificates If you're developing locally and need to use HTTPS for whatever, then this tool is hopefully useful to you. I made it because there's a lot of bad info online about generating self-signed certificates. For instance, a lot of guides don't use the SAN list extension or show you how to create a proper certificate chain. Firefox doesn't allow a CA certificate to be used as an end certificate. Getting a working certificate can get pretty confusing, especially for newcomers to certificates or webdev. Having a website for this also means the process of getting a certificate is the same, no matter if you're on a Unix-like OS or Windows. A WebAssembly module built with C++ and Mbed TLS is used to create the keys and certificates. TypeScript and Preact is used for the UI. https://ift.tt/0jiwJEQ March 18, 2024 at 02:24AM

Show HN: PromptFox, high quality Midjourney prompts As a traditional artist, at first, I had conflicting sentiments about generative AI. The fact that centralized companies were scrapping and using content from people who poured years of work into felt wrong. But I can't deny the massive opportunity it created for everyone to explore their creative ideas, and redefine the base level of the global output of art. The first months were so exciting, with everyone experimenting and sharing their newly found insights. Nowadays, I find more and more people being secretive about their process and their prompts… That's not the vision I want for this space. If we're crowdsourcing the work of millions of artists, gatekeeping your own feels wrong to me. I want an open space where ideas are shared, remixed, and applied in an infinite number of ways.

Today is just the first step on that journey. We hope you'll take a peek at our

Show HN: Phospho – Text Analytics for LLM Apps (Posthog for Prompts) Hello HN! Pierre and Paul here. We are building an open source text analytics tool for user inputs and LLM app outputs The repo is https://ift.tt/Lji76TO and landing is https://phospho.ai Most people building with LLMs today don’t have quantified evaluation and usage metrics on the interactions between users and their product. The only solution is to read every message (or a sample) to get a sense of what is going on. You can't improve your product without understanding who your users are and how they are using it. Nobody would launch a website without standard analytics today; the same principle should apply to LLM products. We made phospho to analyze the large amounts of text from user inputs and LLM app outputs, and give you quantified and actionable insights. You first log messages and set up semantic events. Eg: “user is talking about sports”, “assistant didn’t quote the source”. We then run asynchronous jobs

Show HN: StableBuild – make any Docker container deterministic Hi HN! I've posted this a few weeks back without much HN traction - today we've added a free community tier, so anyone can try it out. TL;DR: We’ve launched StableBuild, a new tool to easily freeze and pin Docker images, operating system packages, Python packages, and arbitrary build dependencies; in 5 lines of code: https://stablebuild.com . As the CTO at an ML startup w/ 75 people ( https://ift.tt/DqGBCzE ) I’ve grown incredibly frustrated with non-deterministic builds. Last year basically every week one of our containers (we have 40+ unique ones in prod) would stop working properly because some dependency was updated or removed. This ranges from Nvidia deleting cuda base images from Docker Hub, to Chromium being removed from the Ubuntu package registry in favor of the snap version, to pandas 2 being published with breaking APIs - while everyone just depends on e.g. pandas>=1.4. This has been super disruptive b

Show HN: Run `SSH bitbop.io`, get a personal GPU dev machine Hi HN! I've been hacking on this side project for the last month or two with the goal of making it dead simple to use cloud GPUs. I ran into this problem personally during the phd, and built my own tooling around it. I always thought it'd be fun to try to turn that tooling into a more general product... and bitbop.io is the result! All you have to do is run `ssh bitbop.io`, and you get your own personal dev GPU workstation in the cloud. Looking forward to hearing your thoughts! https://twitter.com/SamuelAinsworth/status/1767596818366427441 March 13, 2024 at 12:16AM

Show HN: Cahier – A knowledge base with native support for research I'm happy to be on Hacker News to present my most recent project. Cahier is a personal knowledge management system created to support out of the box the research workflow. It allows you to both store and consume study documents (PDFs, web pages, etc.), manage the annotations from those documents, and produce written content based on them. It goes further than existing reference managers because we chose to make the annotation management a part of the application, so you can organize and centralize highlights in notes and special document elements. It's a local-first, native application for Windows and macOS, created to be a research companion for serious readers. Here's a more detailed method that uses the app: https://ift.tt/9C0N2MY... https://getcahier.com March 12, 2024 at 07:17PM

Show HN: Prompts as (WASM) Programs AICI is a proposed common interface between LLM inference engines (llama.cpp, vLLM, HF Transformers, etc.) and "controllers" - programs that can constrain the LLM output according to regexp, grammar, or custom logic, as well as control the generation process (forking, backtracking, etc.). AICI is based on Wasm, and is designed to be fast (runs on CPU while GPU is busy), secure (can run in multi-tenant cloud deployments), and flexible (allow libraries like Guidance, LMQL, Outlines, etc. to work on top of it). We (Microsoft Research) have released it recently, and would love feedback on the design of the interface, as well as our Rust AICI runtime.

Show HN: Wife couldn't find a dev job so I built a tool to automate the search Hey everyone, My wife graduated in 2022 and she was fortunate enough to land an internship at a small startup which then offered her a permanent position. But ever since then she has been trying to find another job as a frontend dev since the current one doesn't offer any growth opportunities. She started looking in 2023 right when the job market started tanking. She's been at it for months with no success as there are little to no junior roles available and she spent most of her day refreshing linkedin to check for new opportunities. At the beginning of this year I had this idea that I could automate the job search part for her by web scraping the search results page in linkedin. This way she could focus on work/portfolio projects and check when the tool finds new job opennings. Long story short, what started as a small script evolved into a full fledged project since I realised this could help

Show HN: wallstreetlocal – View investments from America's biggest companies Hello Hacker News! My name is Anonyo, and I am a seventeen-year-old from Southeast Michigan. This is wallstreetlocal, my passion project for the last year (and a half). I've posted this before, but I've finally open-sourced this entire project, so I thought I'd post it again. Heres the short pitch. The Securities and Exchange Commission (SEC) keeps record of every company in the United States. Companies whose holdings surpass $100 million though, are required to file a special type of form: the 13F form. This form, filed quarterly, discloses the filer's holdings, providing transparency into their investment activities and allowing the public and other market participants to monitor them. The problem though, is that these holdings are often cumbersome to access, and valuable analysis is often hidden behind a paywall. Through wallstreetlocal, the SEC's 13F filers become more accessible an

Show HN: Hatchet – Open-source distributed task queue Hello HN, we're Gabe and Alexander from Hatchet ( https://hatchet.run ), we're working on an open-source, distributed task queue. It's an alternative to tools like Celery for Python and BullMQ for Node.js, primarily focused on reliability and observability. It uses Postgres for the underlying queue. Why build another managed queue? We wanted to build something with the benefits of full transactional enqueueing - particularly for dependent, DAG-style execution - and felt strongly that Postgres solves for 99.9% of queueing use-cases better than most alternatives (Celery uses Redis or RabbitMQ as a broker, BullMQ uses Redis). Since the introduction of SKIP LOCKED and the milestones of recent PG releases (like active-active replication), it's becoming more feasible to horizontally scale Postgres across multiple regions and vertically scale to 10k TPS or more. Many queues (like BullMQ) are built on Redis and data loss can

Show HN: Control Panel for YouTube Hi HN, I recently released a new browser extension for YouTube, which in addition to the table stakes of hiding the existence of Shorts, hiding promoted content, automatically skipping ads, hiding useless/unused UI elements, hiding unwanted channels YouTube keeps recommending to you, letting you hide algorithmic suggestions etc. etc., makes other changes I've always wanted as a user, in the same vein as one of my other extensions, Control Panel for Twitter. The most significant of those is attempting to make your Subscriptions page more like an Inbox, by hiding videos you've already watched (with a configurable watch %), videos you're never going to watch (like live streams and multi-hour stream VODs - if you follow any gaming channels which started co-streaming to YouTube after a recent Twitch policy change), videos you literally can't watch (Upcoming), and improving the handling of videos hidden using YouTube's built-in Hide func

Show HN: My first software project- a website to set goals and track progress Two years ago, I started building this site that allows people to document their learning and progress in real time. The idea is: as you learn new things, you document your progress piece by piece, creating a collection of failures, breakthroughs, and knowledge. Along the way, your friends can cheer you on, and the community can give you tips and feedback. Over time, we'll create a public collection on how different problems were solved. With each progress, the site prompts you to reflect on questions like, "If you could go back in time, what do you wish you had known?" This was my first web dev project, and everything was self-taught. It's been both a great passion and a significant learning experience! All feedback is welcome, big or small. I hope you enjoy it and find it useful. Stack: Angular, Python/Postgres, AWS, PWA service workers for notifications. March 8, 2024 at 12:15AM

I’d really appreciate your feedback and encouragement! This project lets me solve some of my OCD problems online. There are a couple of parts of the forums that I visit – Space Battles, Sufficient Velocity, and Questionable Questing – that I want to remove. Specifically, I hate seeing indicators of how much is left in a forum thread, because I keep thinking about how much content is left. It stops me from immersing myself in the story. It stressed me out. Before I learned to code, I'd use my hand to block the total chapter count so I could read the blurb and see the word count. I would do my best to ignore the page navigation bar except for the next page button, but I usually ended up failing. One of the reasons I always read in full-screen Safari is that I didn't have to see the ta

Show HN: Daytona – Open-Source Dev Env Manager from a 15-Year Journey Hey HN, I'm Ivan Burazin, and for the past 15 years, I have been on a mission to streamline software development environments. Today, I'm excited to share the culmination of that journey: Daytona, an open-source Development Environment Manager designed to finally solve the issue of setting up dev environments, whether local or remote. My journey in cloud development began in 2009 when my cofounder and I we launched the first (or at least one of) commercial Cloud IDEs, Codeanywhere. We developed everything in-house: the IDE, the orchestrator, and more. We garnered interest from over 2.5 million developers, and although it makes sense now, then we were ahead of our time. Fast forward to today and remote development is commonplace, but the complexity of setting up environments has grown by a magnitude. This is where Daytona comes in. - What is Daytona? Daytona is an open source, single-binary Development Environ

Show HN: Share multiple screens simultaneously in Microsoft Teams Hey, HN! We built the ability for multiple people to share their screen at once in Microsoft Teams. Was a journey figuring out how to use and abuse Teams APIs to essentially get a Teams call embedded in a Teams call... In the end though, it is so powerful for everyone to be able to share their screens at the same time, and not have to "wait their turn". We use it every day for all sorts of collaborating, planning, etc. You can use MultiShare for free by installing from AppSource or by clicking the [+ Apps] icon from a Teams meeting and searching for "MultiShare".

Holoib is a platform that allows you to create interactive product demos in minutes and share them via a link or embed them anywhere. It also enables you to collect leads; you can add a form at the CTA of the demo. Additionally, using AI, you can translate the demos into different languages and add a synthetic voiceover. In the last month of 2023, I launched this product. Since then, I have been continuously working on improving it. Initially, the product was very basic, but thanks to feedback from my users, it has been improving day by day. If you try Holoib, I hope that you have a great experience!
