Show HN: Flat – simple task tracking that stays out of your way Hi HN! Flat’s a lot like Trello, but with a cleaner, simpler, friendlier UI and real discussion threads. Flat also sports a first-class GitHub integration. To take it for a spin without signing up, just go to https://try.flat.app . And there’s also a quick demo video here: https://youtu.be/NW2c9cZVaD0 We made Flat for ourselves, after a decade of wanting a simple, lightweight tool to stay on top of our work and not finding one. Trello is close, but we find it really frustrating to use in lots of ways. And most everything else is way too complex. We think there’s a need for a task tracker that prioritizes simplicity, clarity, and usability over bells and whistles that most users don't need. And like many folks who are burned out on team chat, we also think there’s a need for a mode of workplace communication that’s lightweight, async, and attached to the work rather than chats in Slack or Teams where it’s too easy for things to get lost (and to be interrupted all day). Flat doesn’t try to replace Slack--chat will always have its uses--but it does offer a better venue for a subset of Slack’s workload, like asking and answering questions, making quick requests, and raising issues about things the team is working on. Flat is aimed at small teams with basic needs. Small dev teams without a lot of process seem to love it, as do people who used to like Trello back in the days when it was less stressful to use, and people for whom Asana’s complexity is a non-starter. Flat is still in beta, so it’s probably missing some things you expect, but what’s there is pretty baked. It’s available in-browser as well as Electron apps for Mac, Windows, and Linux (.deb) Feedback is welcome and greatly appreciated! Either in the comments here, or if you sign up there's also a feedback button in the app navbar for whenever something irks you or you have an idea. Thanks, Seth, Andrew, & Marcin https://flat.app/ February 29, 2024 at 11:33AM

Show HN: Marimo – open-source reactive Python notebook – running in WASM https://ift.tt/3dzQPaF

Show HN: Marimo – open-source reactive Python notebook – running in WASM Hi HN! Last month, we shared marimo [1][2], an open-source reactive notebook for Python. For those who missed it, marimo notebooks are reproducible, stored as Python files, executable as Python scripts, and deployable as web apps. It’s now possible to run marimo notebooks entirely in the browser via WebAssembly (WASM). - A marimo tutorial as a WASM notebook: https://ift.tt/Im3jWrV - Training a neural network with Karpathy’s micrograd: https://ift.tt/O9unm7g - Visualizing attractors, as a read-only app: https://ift.tt/plHUO8F - A blank notebook: https://marimo.new - Docs: https://ift.tt/x25NC1p WASM notebooks let you experiment with code without having to install Python on your machine. These notebooks can be easily shared — marimo includes a button that generates a marimo.app URL (code encoded as a query parameter), and marimo.app has a built-in permalink generator. We also support embedding via iframes: you can use this to (say) author interactive documentation or standalone interactive blog posts. We now in fact use embedded WASM notebooks throughout our API docs. Our WASM notebook is powered by Pyodide [3], a WASM-based Python distribution. Pyodide can run any Python package that has a pure Python wheel, as well as many popular libraries for scientific computing and machine learning, including Pandas, NumPy, SciPy, and scikit-learn. Over time, we expect more and more libraries to be packaged for Pyodide. We’re very excited by the potential of WASM notebooks to make computing more accessible, and we’re in awe of all that the WASM and Pyodide contributors have accomplished. We have lots more planned (one example: we plan to make it easy to work with local files), and hope to share new developments with you in the future. In the meantime, please try https://marimo.app out. We’d appreciate feedback! P.S. Our support for WASM is very new; you may encounter sharp edges. Still, since WASM-compatibility was one of the most requested features from our previous HN, we felt it was worth sharing.

Show HN: CriticalPath – Advanced Profiler for Android https://ift.tt/dac57KP

Show HN: CriticalPath – Advanced Profiler for Android I am excited to announce the project I am working on: an advanced mobile app profiler for Android. Its primary purpose is to optimize app performance and make it faster. Additionally, it serves as an excellent debugging tool. The main distinction between existing tools, such as Perfetto and the Android Studio Profiler, is the ability to synchronize the trace with a video recording of your app. This allows you to see the app's UX alongside what's occurring within the app to identify what's causing slowdowns. Another key feature is the ability to click on any slice and view the cross-thread execution path of function calls, tracing from a user action to the selected slice. This makes it easier to identify performance regressions: slow functions, suboptimal network calls, or functions clogging the main thread. Additionally, we have implemented smart code instrumentation that has a minimal impact on performance. I am one of the developers of this tool. The project is in active development and are eager for feedback from Android developers. You can try it out at https://crpath.app https://crpath.app February 29, 2024 at 02:22AM

Show HN: Velvet – Data platform with an AI SQL editor https://ift.tt/2MO7eyf

Show HN: Velvet – Data platform with an AI SQL editor Hi HN — Chris here, Velvet co-founder. I’m excited to share what we’ve been working on, a platform to unify disparate data sources into a single queryable interface. We built Velvet to solve our own problem. We’re a small team and wanted to combine the data from various services (Stripe, Supabase, etc.) into a layer that would help us make product decisions and ship new features faster. On the surface, it may look like a simple text-to-SQL data notebook. But under the hood, it’s an accessible and interoperable backend-as-a-service that your entire product team can utilize. Connect to your databases, sync third-party APIs, capture webhook events — then write data directly, spinning up queues and analytics databases on the fly. The magic of our tool is in unifying data sources into a native SQL layer. We leverage ClickHouse to enable you to write joins across datasets you’ve never been able to pair together before (without significant effort). We layer on an iterative SQL query interface to help you write and refine queries with the assistance of AI. Our product works great for individual contributors and solo devs, but we’ve also built in collaboration features so data access doesn’t get siloed. Your saved queries can be turned into API endpoints and used directly in feature development. This makes the workflow of shipping new features really fast! Ping me if you want to early access to this feature. Watch our video demo ( https://youtu.be/CW5TXMCyfC0 ) and try the live demo in our app. Feel free to email me directly (chris@usevelvet.com) with questions and feedback. Thanks for checking out Velvet! https://ift.tt/ZuAl4jk February 27, 2024 at 11:41PM

Show HN: Scribbler - An open source notebook tool for JavaScript https://ift.tt/pQH2l91

Show HN: Scribbler - An open source notebook tool for JavaScript Scribbler is a tool to do experimentation in JavaScript using a notebook kind of environment. It runs in the browser without the need for a backend. It is deal for learning and experimentation in JavaScript. USP of Scribbler are: no login, no node/npm, can load ES 6 modules. Check the website at: https://scribbler.live . The web-app is available at: https://ift.tt/IUM6N3R . Scribbler has been built to satisfy a need for doing experimentation. Jupyter Notebook is very popular amongst python developers and data scientists for experimentation. It gives a simple interface for experimenting in python for testing code or for experimental analysis. Jupyter Notebook provides this application by running what is known as a “kernel” in the backend and giving back the results to the ui for display. It is an open source and free to use tool. Thus it has become extremely popular. As it is in Python, it requires installation of python environment and the libraries to use the tool. There are fully hosted alternatives like Google Colabs, where one can experiment in Python without installing anything. There is no similar open source tools for Javascript. There are online tools like jsfiddle/codepen etc but none that can be downloaded and used as a free tool or embedded on other solutions. Pure Javascript and JS libraries can ideally run without the need for a backend code like node.js or Python. Javascript is built to run by default in the browser. Optimization of the browser tech by Chromium (i.e. V8) and Firefox has ensured Javascript in the browser is fast and efficient. Thus we can build a good notebook tool using just front end technologies. I’ve been looking for such a solution for quite sometime mainly to test out some of the open source JS libraries and also for building some new open source projects. As I couldn’t find any solution I have built a simple tool to run javascript in notebooks. I call it Scribbler (so much for creativity). It is available as an open source solutions — free to use and modify. The source code is available at: https://ift.tt/YN25E6a It does not require any backend technology. Users can download and use it in the file system or host it in webserver to use it on the internet. I have used Github Pages to host it. As it does not require backend, I need not buy/host a server to do that (ain’t it beautiful?). JavaScript can be used for a variety of experimentation. I’ve learnt a lot about Dynamic systems while using Scribbler to do simulations. It has also helped me in understanding some concepts of decentralized finance. I’ve also used Scribbler to solve some equations using numeric methods. Given the dynamic nature of JavaScript and its close integration with the UI, one can use it for building charting/dahsboarding tools. Scribbler can infact be even used for data science and machine learning. JavaScript has a vibrant community with a wide range of libraries available. Thus the usecases of Scribbler are limitless. I hope as more people start using Scribbler, there will be more and more applications including interactuve data science, Generative AI, scientific simulations, financial/economic applications, decentralized computing etc. Happy experimenting!! https://ift.tt/IUM6N3R February 27, 2024 at 10:17PM

"Continuous-eval" came from our efforts to measure, validate and improve the reliability of a finance AI copilot we were developing for banks. End-to-end evaluation was not enough for us. We wanted to have granular evaluations that help pinpoint the bottlenecks and identify what / how to improve. We’ve since developed more metrics and made the framework more flexible so it can evaluate components like agent tool use, code change, retrieval steps, etc. Let us know what you think of our approach to GenAI App evaluation. https://ift.tt/68l5tSX February 26, 2024 at 12:11AM

Show HN: Refractify: optical software against Myopia https://ift.tt/0p8dkay

Show HN: Refractify: optical software against Myopia Last summer there was an Ask HN[1] about a Nature article that said bluring the blue and green color channels on screen may be good against early myopia development. The OP wanted such software and there was none available. So I quit my job and implemented this software, did a short video with a 3D artist about it. Turns out marketing is expensive, so I made an open source browser extension version too. How it works? There is a small neural network on the retina that tries to detect if the eye is far-sighted(most people are born far-sighted), and it is producing dopamine to slow or increase eye growth rate. It is not very smart, and if you do a lot of near-work it can think you are still hyperopic, causing further myopia progression. So, based on the refractive properties of the eye the software calculates the signal that would convince the retinal neural network that the eye is long enough, so it would produce dopamine, a known signal to stop axial eye growth. (based on myopic defocus LCA from the papers[2][3]) Some myopia control techniques work similarly, like MiSight and Hoya lenses. Since then I got a Neurobiologist co-founder and the goal is to best understand the Retinal NN to create the best anti-myopic effect that does not interfere with productivity. The effect can be tried live on the site. Also check out the github repo. Any questions suggestions welcome!

Show HN: Learn Game Theory Optimal Poker Preflop with Spaced-Repetition https://ift.tt/FApqiL1

Show HN: Learn Game Theory Optimal Poker Preflop with Spaced-Repetition Hi HN, Sharing my poker preflop trainer product, a subset of my Live Poker Theory project. https://ift.tt/fQXz3BY Live Poker Theory helps translate complex poker solver strategy to actionable strategies while playing and aims to make studying poker more efficient and more fun. While I usually try to focus on sharing it in poker communities, I saw a few poker articles frontpage this site so I figure it doesn't hurt to share it here. In case you don't know, before 2015 most poker software could only calculate "all-in equity" - if there was no game tree and players could only go all-in or fold. These days, solvers can calculate the full game tree, with a lot of assumptions, and we can use them to generate preflop charts. Sometimes people call this GTO (game-theory optimal) though I prefer the term "theory-based" to recognize how frequently you want to diverge from equilibrium even if you've studied it. Preflop refers to the first two cards you're dealt and the first round of betting which is a very fundamental street. Preflop is a good example of where I find it useful to study equilbrium even if you might diverge in practice - for example, once you understand how often a player should be 3-betting you (re-raising you after you've raised), if you know someone doesn't do it with hands like Ace-Five suited, you can fold hands you'd otherwise continue with. But it's helpful to understand a strong player should frequently be 3-betting Ace-Five suited. Some other info that might be helpful: 1) Rake refers to whether the "house" removes money from the pot which happens at most low-stakes games. Higher stakes games tend to be "time" games where the players simply pay an hourly fee so there's no effect of rake on the game itself. That also may be true at an unraked home game. 2) A straddle is an optional third blind that's often strongly encouraged as something everyone at the table does, and of course the charts are different with that third blind Spaced-repetition is something that only my trainer does, while it's a well understood concept on places like Hacker News, it's not well understood by the poker community. Even if you plan to make adjustments against certain players, there's good reasons to memorize a preflop chart. It helps you stay disciplined if you're "tilted" if you know what a reasonable baseline strategy is. It also helps you clearly define your postflop strategy, both while doing solver work and while playing. For examlpe, frequently the best river bluffs are the "bottom of our range", since our worst hands beneift the most from our opponent folding. But the "bottom of our range" is only clearly defined if our range is clearly defined, so if you've memorized your preflop range, you'll have a better understanding of your overall strategy postflop. One last important note, the charts are based on a 2.5x raise, so in a 2/5 game, a raise to $12, which is fairly rare to see in practice. If you have the solver raise 3x or 4x, the overall strategy is much much tighter. While this is more correct against perfect opponents, in practice frequently we're against weaker opponents and we'd rather play a looser range since we'll have an advantage postflop. By studying 2.5x, we keep a more reasonable loose range but still let the solver give us a reasonable baseline of hands to play. Currently, you can try out Tournament, 50 Big Blind stack depth, Raise First In without an account. With an account and for free, you can study cash or tournament "Raise First In" (whether to raise or fold if it folds to you), "Vs Open" (whether you raise, fold, or call if someone raises before you act), for free, for cash or tournaments. I have paywalled only cash game BB defend (if someone raises when you're in the big blind) for $10/mo or $59/year. I'm also actively adding more preflop charts, developing postflop content with spaced-repetition and a native mobile app. https://ift.tt/fQXz3BY February 23, 2024 at 01:06AM

Show HN: I scraped 200M Shopify products to build a search engine https://ift.tt/E3q5Ika

Show HN: I scraped 200M Shopify products to build a search engine Hi HN! In December I launched an MVP for Agora here: https://ift.tt/6tgb1wM After posting, we got thousands of users and hundreds of comments with valuable feedback from the community. I spent a couple sleepless nights frantically pacing around my room trying to keep the product live and, relatively, performant. After getting some sleep, I got back to work to make the product better. A few updates: 1. We've grown from 25 million to 200 million products on Shopify and WooCommerce. The team at WooCommerce reached out after the HN launch to help us figure out how to index their stores. Similar to Shopify, we found that there’s a public file available for all stores that use Wordpress and WooCommerce at [Base URL]/wp-json/wc/v1/products. For example, the file for Good Works Tractors is available here: https://ift.tt/yugcBRX... So I bought a list of 3.5 million active WooCommerce stores on a website called BuiltWith, adapted the product data model, and started the crawler to go down the list. We've indexed around 515k stores so far. 2. We improved the search experience. We're using Mongo to host the 200 million product records. First, we switched from Mongo Atlas Search to Typesense. After testing Typesense with our product records, we found most searches to be under 200ms. We're not storing the product images which slows down the loading speed at times. This week, we set up a server using Paperspace to run SBERT embeddings on a GPU (new to the AI workflow so apologies if I get the lingo wrong). We quickly realized that the dimension size of the embeddings matters a lot here, given the size of the data set. The GPU is still running to process all 200 million records and we're about a week away from releasing AI-powered search. 3. We localized the user experience. There's now frontend and backend IP detection to only show users products that are 'based in' or 'ship to' their specific country. This 'ships to' filter (i.e. stored in all Shopify stores in the /meta.json route like https://ift.tt/zifY1Tv ) significantly slows down the search results but we're trying to get creative on the loading process and animation. For example, we're using Revalidating on Next.JS to give several pages a 'hard coded' feel and the data refreshes every 60 seconds. https://ift.tt/f032xeQ... 4. We got our first few paying customers. Store owners can sign up for free to track their store's performance on Agora. We validate that they are the store owner by making sure the email address and store URL match on sign up, and then send them an email verification link. They can upgrade to a subscription tier to 'verify' their products to get better placement in relevant search results. Additionally, they can pay to 'boost' products and guarantee that they'll show up in the first row of results. Given the high purchase-intent searches on Agora, I'm finding this to be the right business model. The next challenge to solve: We need to improve the quality of products on Agora. There's a lot of resellers, dropshipping stores, and low quality images. Now, just because a product is sold on a reseller or dropshipping website, doesn't mean it's a bad product. There's a lot of exceptions and edge cases to solve. One potential solution: we're considering coming up with an "Agora Score" that takes in several factors including the image quality, store name, brand name, website SEO, etc. to tell users how trustworthy we think the product is. I'd love any feedback or advice. I did solve my original problem of finding 'red shoes' for my wife, but inadvertently created more problems for myself. I'm loving every minute of it though. My wife jokes that everything is now "Agora this...Agora that". Open to any advice on that as well. https://ift.tt/wCPxaqI February 22, 2024 at 04:04AM

Show HN: Wiwo – Find events happening around you. Google Maps, but for events. https://ift.tt/chxgSbC

Show HN: Wiwo – Find events happening around you. Google Maps, but for events. Hey everyone in the USA! I'm developing a map-based event discovery platform that helps people find unique and exciting events in their city or area. I imagine that it could help young locals who are searching what is to be attended in their area & tourists who are visiting and want to find what to do in the area. But before I unleash it on the world, I need your help! One major pain point that I am trying to solve is information overload and difficulty in discovering relevant events nearby. Traditionally, people might rely on social media, local newspapers, or word-of-mouth to find events happening around them. These methods can be: Scattered: Information is spread across different sources, making it time-consuming to search. Unfiltered: Showing a large amount of events, not necessarily relevant to individual interests. Limited information: Often lacking key details like event descriptions, schedules, or ticket options. So my MVP address these issues by: Aggregating: Bringing together event information from multiple sources in one place. Personalization: Using filters and user preferences to recommend relevant events. Visualization: Displaying events on a map, allowing users to discover events based on location and proximity. Detailed information: Providing comprehensive descriptions and links to purchase tickets. What other features I plan to build: Build-in resell marketplace, own event upload, live-streaming, PPV and more. However I find it difficult to get any feedback on the platform. I've tried paid ads, posting to other Early Adopters websites, personally reaching out to people, who I think are target users, but do not get any meaningful feedback. So I'm eager to hear your honest opinions: What works well in the platform? What needs improvement? Are there any features you'd like to see added? Your feedback will be invaluable in shaping the future of Wiwo! P.S. For now only US users are needed, as other won't find events in their areas :) https://ift.tt/MERGNI0 February 22, 2024 at 02:28AM

Show HN: An Experiment with One-Feature Tool Made $7164/Mo https://ift.tt/slzkHbY

Show HN: An Experiment with One-Feature Tool Made $7164/Mo My Raw Story on coming up with an idea, building and growing it. It's very detailed, with the purpose of giving another founder an insider look at one way of doing it. In January I launched an indexing tool called Index Rusher, that forces google to index your pages quicker, to get ranked for SEO faster. This whole project was something I needed myself since I got over 20 products and paying for an external one would simply cost too much. My initial idea was that I would just build an internal tool for my use, that has only 1 feature. No UI really, just 1 button. In the middle of the process, I realized that I could actually run an experiment and launch this tool publically with just one feature. Super simple. I hired a dev who spent a month building it. It looked super easy at first, but it turned out there were so many hidden snakes on the way. Troubles with sitemaps, google APIs, and more. 1 month later I launched it (In Jan). The launch didn't go so great, but I didn't really have high hopes. Because nobody knew about this tool, I had no traffic on the site. I still sold several licenses, which made me pretty happy, it felt like validation, people needed it, even if it solved such a narrow problem. At that point, I declared my next stage of the experiment: Growing the traffic and revenue. I've done a number of growth hacks in the next 30 days, resulting in over $7k in revenue, but what's more important, the traffic on the site has grown a lot and stays high and growing. This means I've done a pretty good job on organic growth too, which will just accelerate over time. Here is what I've done: Cross-linking. I added links in the footer on my other products. This is one hidden effect of having multiple products. Each may serve as a lead magnet for the other one. In my case, I have the same audience for all my tools, people who love one of my tools often check out the rest. Being visible on social media. I monitor discussions around the Google Indexing topics and add my replies there. I don't just spam in replies with my tools, in most cases, I genuinely answer and bring value. If my reply gets a reply, I may include my URL in the next reply. Social Media and Blog posts. I've posted several posts about Growth, where I mentioned Indexrusher since I actually use it for me Growth. Traffic from Directories. This one was the top channel of growth. Over 50% of the paying users arrive from web directories. I used a tool that listed Index Rusher on 100 directories & websites. Sponsored listings. I "sponsored" directories to place a banner for my tool on the top of their page/list. Seeing the effect of "boosted" listings. The ROI was good. About $2.5k of revenue came in from these boosts. Affiliate partners Made a deal with a few affiliate partners who reached out to me on X and he drove a decent amount of traffic and paid users to me since he was launching on PH the same week, The total economy of the project now Dev costs: $1500*3=$4500 - Godaddy domain: $9 - hetzner Hosting: $10/mo - landing page on Unicorn Platform: $9/mo - cost of sponsorships: $800 - Affiliate payouts: $150 - listingbott for backlinks: $499 - seobot ai for blog: $99 - Stripe fees: $654 Total cost: $6711 Revenue: $7164 Profit: $453. So, it's profitable! My next steps will be 1) Promote it to 100,000+ users of my Website Builder and reach out to more website builders and pitch them the integration 2) Increase Word-of-mouth effect 3) Perhaps try some paid ads 4) Add automated emails to remind about Index Rusher users who signed up but didn't buy 5) Launch a directory as a lead magnet 6) Launch little free tools as lead magnets 7) Product Hunt launch 8) AppSumo launch I will make a new post in a month describing how it went.

Show HN: Hyperdiv – Reactive, immediate-mode web UI framework for Python Hello HN, I'm releasing Hyperdiv ( https://hyperdiv.io ), a framework for rapidly developing reactive browser UIs in Python, with immediate-mode syntax and using Shoelace ( https://shoelace.style ) as its built-in component system. This short coding video will give you a good idea of what it is: https://www.youtube.com/watch?v=4XJKfxaqvGE I wrote a brief article about the motivation and approach: https://ift.tt/7vMqYEd Hyperdiv doesn't aim to compete with serious full-stack frameworks. The core aim was to make it easy and fast to prototype apps and build UI-based tools. I was originally motivated by internal tools at work -- feeling the need to quickly put together UI-based tools to share with both technical and non-technical coworkers, without having to stand up and maintain a full internal stack. This is my first major open source release. I really appreciate your feedback and support. - Marius https://ift.tt/OYv4KT2 February 20, 2024 at 07:53PM

Show HN: Caps-log (Captain's log) – A small TUI journaling tool https://ift.tt/2UoER0W

Show HN: Caps-log (Captain's log) – A small TUI journaling tool Caps-log is a compact TUI (Text-based User Interface) journaling application crafted in C++ and leveraging the FTXUI library for its terminal interface. It allows users to save daily log entries as simple markdown files, making it an appealing tool for those who prefer working within a terminal environment. The interface is designed with a calendar feature that stands out by marking the days associated with a log entry. Furthermore, it can accentuate days based on specific 'tags' or 'sections' identified in the logs, which are either markdown list items starting with '*' or level one headers. In addition to these features, caps-log includes password protection for your entries and offers a somewhat 'hacky' (for now) method for remote storage. This is achieved by integrating with a pre-configured Git repository, enabling remote storage via a git remote. https://ift.tt/Wpjs5xF February 19, 2024 at 01:07AM

Show HN: I Built an Open Source API with Insanely Fast Whisper and Fly GPUs https://ift.tt/bNDI7eV

Show HN: I Built an Open Source API with Insanely Fast Whisper and Fly GPUs Hi HN! Since the launch of JigsawStack.com, we've been trying to dive deeper into fully managed AI APIs built and fine tuned for specific use cases. Audio/video transcription was one of the more basic things and we wanted the best open source model at this point it is OpenAI's whisper large v3 model based on the number of languages it supports and its accuracy. The thing is, the model is huge and requires tons of GPU power for it to run efficiently at scale. Even OpenAI doesn't provide an API for their best transcription model while only providing whisper v2 at a pretty high price. I tried running the whisper large v3 model on multiple cloud providers from Modal.com, Replicate, and Hugging faces dedicated interface and it takes a long time to transcribe any content about ~30mins long for 150mins of audio and this doesn't include the machine startup time for on-demand GPUs. Keeping in mind at JigsawStack we aim to return any heavy computation under 25s or 2mins for async cases and any basic computation under 2s. While exploring Replicate, I came across this project https://ift.tt/vXBwdfo by Vaibhav Srivastav which optimises the hell out of this whisper large v3 model with a variety of techniques like batching and using FlashAttention 2. This reduces computation time by almost 30x, check out the amazing repo for more stats! Open source wins again!! First, we tried using Replicate's dedicated on-demand GPU service to run this model but that did not help, the cold startup/booting time alone of a GPU made the benefits of the optimised model pretty useless for our use case. Then we tried Hugging face and modal.com and we got the same results, with an A100 80GB GPU, we saw around an average of ~2mins start up time to load the machine and model image. It didn't make sense for us to have an always on GPU running due to the crazy high cost. At this point, I was inches away from giving up. The next day I got an email from Fly.io: "Congrats, Yoeven D Khemlani has GPU access!". I forgot the Fly started providing GPUs and I'm a big fan of their infra reliability and ease of deployment. We also run some of our GraphQL servers for JigsawStack on Fly's infra! I quickly picked up some Python and Docker by referring to a bunch of other Github repos and Fly's GPU tutorials, then wrote the API layer with the optimised version of Whisper 3 and deployed it on Fly's GPU machines. And wow the results were pretty amazing, the start up time of the machine on average was ~20 seconds compared to the other providers at ~2mins with all the performance benefits from the optimised whisper. I've added some more stats in the Github repo. The more interesting thing to me is the cost↓ Based on 10mins of audio: - OpenAI Whisper v2 API -> $0.06/10mins - Insanely Fast Whisper large v3 API on Fly GPU (Cold startup) -> ~$0.029/10mins - Insanely Fast Whisper large v3 API on Fly GPU (Warm startup) -> ~$0.011/10mins (Note: These are rough estimates I did by taking averages after running 5 rounds each) If you guys want to run this on any other GPU providers you can as long as they support Docker. We'll be optimising this more over the next few days specific to Fly's infrastructure allowing for global distributed instances of whisper and will soon be providing a fully managed API on JigsawStack.com. Stay tuned! https://ift.tt/aujtzOR February 18, 2024 at 01:48PM

Show HN - tool that converts image receipts to Excel https://ift.tt/tLPh3qN

Show HN - tool that converts image receipts to Excel Hey I'm excited to share my first project, Receipts2CSV, a web application designed to simplify bookkeeping by converting receipt images into CSV files. https://ift.tt/bGLovty Problem Statement: Keeping track of expenses and managing receipts can be a tedious task, especially for small businesses and freelancers. Traditional methods involve manually entering data from receipts into spreadsheets, which is time-consuming and prone to errors. With Receipts2CSV, users can streamline this process by simply uploading images of their receipts and obtaining structured CSV files ready for import into accounting software. If you are lazy like I am, you could accumulate receipts in just one folder and re-run all images every time, remove duplicates and merge with older CSV to minimize looking through receipts on a monthly/annual basis. Questions for Validation: Do you find a receipt image to CSV converter useful? Would you consider using such a tool for your bookkeeping needs? Considering higher costs for AI models like GPT-4 Vision Preview, how are other indie hackers able to create and sustain offering free products like these? Do small products like these have a monetization market? If so, where do I begin? Curious to hear your candid thoughts about this web app. Should I explore it further or move to the next idea? Feel free to share your thoughts, suggestions, or any additional features you'd like to see in the product! Thank you for your valuable input and support! https://ift.tt/wrB6PWL February 17, 2024 at 11:35PM

Show HN: Host a planet-scale geocoder for $10/mo https://ift.tt/rPolCVO

Show HN: Host a planet-scale geocoder for $10/mo For the uninitiated, a geocoder is maps-tech jargon for a search engine for addresses and points of interest. Geocoders are expensive to run. Like, really expensive. Like, $100+/month per instance expensive unless you go for a budget provider. I've been poking at this problem for about a month now and I think I've come up with something kind of cool. I'm calling it Airmail. Airmail's unique feature is that it can query against a remote index, e.g. on object storage or on a static site somewhere. This, along with low memory requirements mean it's about 10x cheaper to run an Airmail instance than anything else in this space that I'm aware of. It does great on 512MB of RAM and doesn't require any storage other than the root disk and remote index. So storage costs stay fixed as you scale horizontally. Pretty neat.

I'd originally built it for Telegram and Slack, but I've been long interested in doing things with print: printing has long felt like one of the biggest underutilized output processes out there. Almost every piece of software has print integration, the output format is usually legible and for things like receipts I always find myself printing them out, and then copying them to Google Drive. So I built a custom IPP printer: no drivers needed on Windows, OSX or Android (haven't tried iOS yet but I assume its the same), easy configuration and prints PDFs that appear right in your cloud storage location of choice (handy replacement for the missing Google Cloud Print feature). Future work includes parsing the printed PDFs for things like conversion into a Kindle book, or extracting financial data. Feedback welcome! https://ift.tt/qo4Vn7v February 16, 2024 at 01:02AM

Show HN: Natural Language to SQL "Text-to-SQL" API https://ift.tt/9fPvFjY

Show HN: Natural Language to SQL "Text-to-SQL" API Hi HN- Today, we are releasing the hosted API for our natural language to SQL engine, which allows you to: (1) Explain Your Data: Feed in dictionaries, dbt, schemas, Confluence docs - we'll understand the business context to your data. (2) Train Your AI: Fine-tune an LLM (including GPT-4) specifically for your data, increasing accuracy and lowering latency (3) Trust the Answer: See confidence scores with each AI-generated query, stay in control. (4) Conduct complex SQL queries Problem background - Developers struggle to build NL-to-SQL into products because LLMs do not work out-of-the-box; they lack metadata and business definitions. Existing NL-to-SQL tools struggle with context, complexity, and adapting to your data. For example, given the question “what was the average rent in Los Angeles in May 2023?” a reasonable human would either assume the question is about Los Angeles, CA or would confirm the state with the question asker in a follow up. However, an LLM translates this to: select price from rent_prices where city=”Los Angeles” AND month=”05” AND year=”2023” Dataherald integrates with major data warehouses, including PostgreSQL, Databricks, Snowflake, BigQuery, and DuckDB. You can try it now free – no fees, no credit card, no sales pitches, just get the API key and get going. Let us know if it works for you, even your complex queries. ( https://ift.tt/pXJOuKn ) While the open source version works just fine ( https://ift.tt/xLfziVP ), the hosted API might be a better fit for those looking for: (1) someone else to take care of infrastructure setup, (2) access to an Admin UI console where you can configure and monitor performance, and (3) ability to invite team members to a project. We're looking for feedback, particularly from anyone who can compare this performance to other NL-to-SQL products. Share your thoughts and join the conversation For more background on the release: https://ift.tt/s6qE4mr https://ift.tt/pXJOuKn February 15, 2024 at 12:33AM

Show HN: FoldMation – Interactive origami learning and creation https://ift.tt/IDrn8dg

Show HN: FoldMation – Interactive origami learning and creation Hi, I've created an application where you can follow step by step origami fold instructions, and a Creator where you can make these interactive folds. On comparing to video instructions, you have the ability to quickly skip/rewind steps and replay a complicated step many times. On the creation side, there have been one or two attempts at this before, but those solutions rely on mouse drags as the user interface. This greatly limited the kinds of folds possible. The foldMation Creator uses commands, keywords and values to compose a domain specific language/step and provides a (relatively speaking) easy to use user interface to compose the steps. For those interested in using the Creator, please go through the tutorial at the top of the create page. Btw, the DSL for foldMation uses https://ift.tt/UdwGx15 . I created it since I couldn't find anything out there that is similar, allowing me to specify a well structured data with English-like readable syntax.

Show HN: Linen.team – A lightweight, thread-first Slack alternative https://ift.tt/YhDRIgl

Show HN: Linen.team – A lightweight, thread-first Slack alternative Hi HN! I'm Kam, the founder and one of the authors of Linen. Today, we are launching Linen.team ( https://linen.team/ ), a lightweight threaded messaging app for your team. Modern workplace messaging apps (like Slack) are based on IRC, which is great for small groups, but as it scales, breaks down quickly: you either get overwhelmed by notifications or you have to turn them all off. Most chat apps have threads tacked on but aren't built from the ground up with this design in mind. We wanted to create a thread-first experience where you can organize and prioritize conversations so that you are not reliant on notifications to make sure you don’t miss anything. In apps like Slack, you have to check activities, channels, threads, and replies just to make sure you aren't missing anything important. We designed every message in Linen to belong to a thread, so it makes it easy to centralize everything in a single location. We let you select which channels you subscribe to from your inbox. This way, your inbox only has the important channels. This makes it easy to keep track of conversations without having to rely on notifications to make sure you don’t miss anything. We also wanted a better way to separate urgent vs. non-urgent communication. In Linen, we have introduced the concept of a !mention that is designed for urgent/time-sensitive messages. A !mention will send a push notification, whereas an @mention will show up in the person’s inbox. This allows us to encourage more async conversations and reduce the need for the number of push notifications. We also designed the mention system closely with the inbox so that even if you aren’t subscribed to channels, mentions will still appear in your inbox. This is great for joining partner teams where you don’t need to view every conversation but do need to respond when you are mentioned. We believe that most messaging apps are secretly to-do lists in disguise; you have to read, respond, or do some task when you receive a thread. We wanted to give you the ability to manage threads individually. We let you mark each thread as done, which hides them from your inbox and is useful to keep track of tasks. You also can set reminders and mute threads with one click/key. With these features, we make it easy to get to a zero inbox state. This combined with the inbox makes it easy for you to keep track of conversations and make sure you don’t miss anything. Linen is designed for power users. We love keyboard shortcuts and want an experience that is keyboard-first. For many, the messaging app is the app that is used the most. We believe that you should be able to use Linen for an entire day without touching the mouse. We’ve added modern features like CMD+K for navigation. We’ve designed Linen to be fast and lightweight. Our gzipped bundle size is 400KB, so it's fast on first load, and we’ve introduced multiple layers of caching to make sure things are fast on subsequent loads. We’ve been working hard on this app for the past 6 months, so there are still gaps in the platform. But we’re also very excited about the direction we can take. Our focus is on what a modern message platform built in 2024 should look like and what lessons we can take from the previous decades of IRC and messaging apps. If our message resonates with you, we would love for you to give us a try at https://ift.tt/kXCz5As , where you can join our public community and come say hi! February 13, 2024 at 08:01PM

Show HN: The Namingless Programming Language https://ift.tt/WEX3lmp

Show HN: The Namingless Programming Language A programming language that avoids naming at all costs. Data structures don't have names since there is only one data structure and there is no point naming it other than 'the data structure'. There is only one operation, so also unnamed. Even the language itself doesn't have a name. "The namingless programming language" is a definition. But the most cool feature is that when you write a script, you don't have to give the file a name either. The file name itself becomes the code. The file body is the executable interpreter. Is it beautiful? No. Is it practical? Hell no. Is it fun? More than you'd think it would be. https://ift.tt/42UEyYo February 14, 2024 at 01:38AM

Show HN: Swift Mail, a native macOS app for JMAP mail https://ift.tt/0M5VbH9

Show HN: Swift Mail, a native macOS app for JMAP mail Hello HN! I'm excited to share Swift Mail, a native macOS email client purpose-built for the JMAP mail standard. Primarily constructed with SwiftUI with occasional AppKit elements, Swift Mail combines the speed and efficiency of a modern mail standard with desktop-centric features such as system notifications, keyboard shortcuts, quick look, multiple windows, state restoration, dark mode, and more. Swift Mail distinguishes itself from other email clients with its steadfast commitment to the JMAP standard over the traditional IMAP implementation, facilitating seamless alignment with modern mail features. It supports various innovative Fastmail features, such as multiple sending identities, the ability to send or reply on-the-fly from wildcard (*) aliases, and the ability to swiftly transition between (true) label and folder organization schemes. Swift Mail prioritizes user privacy and does not collect any user data or function through intermediary servers. Instead, it directly connects to the JMAP server with the user's provided account credentials, processing and storing all data locally on the user's device. Currently, Swift Mail is available directly via the Mac App Store with support extending back to Monterey. I’m also running a developer build on visionOS (if you have hardware and are interested in testing a beta release, please reach out to beta at swiftmail dot io). A sincere thank you to everyone who has contributed their valuable insights or participated in beta testing via TestFlight thus far. Looking forward to your feedback! - Karl https://swiftmail.io February 13, 2024 at 07:34AM

Show HN: Oration (iOS) turns pdfs into audiobooks https://ift.tt/5Yl6tFo

Show HN: Oration (iOS) turns pdfs into audiobooks Hello HN community! I'm excited to introduce a project I've recently launched: Oration, an iOS app designed to convert PDFs into audiobooks. This idea was inspired by my experiences as an engineering student with ADHD, struggling to engage with dense academic papers. Relying on Text-to-Speech tools, despite their robotic quality, was a workaround for me and others with similar learning preferences or challenges, such as Dyslexia. Recognizing the limitations of existing tools—difficulty with complex formats, inability to skip over citations or footnotes, and inadequate handling of tables, graphs, and figures—I developed Oration. Our goal is to refine these areas continuously, offering both summarized and full versions of PDFs for a more accessible learning experience. Oration aims to serve as a high-quality, user-friendly platform for auditory learners and those who find traditional reading methods challenging, with features akin to popular audiobook apps like Audible or Spotify. How Oration Works: 1. Download the app and sign up using either a username and password or through Google, with a 2-week free trial that doesn't require a payment method. 2. Upload a PDF document. 3. Within about 5-10 minutes, you'll receive a notification that your Audiobook is ready. 4. Listen to your Audiobook directly in the app or through a browser-based web player, which also facilitates easy sharing with friends and family. Also, to emphasize - all audio generated by the user is yours to own! We're working on some updates to easily export .MP3 files of Oration Audiobooks you create For an example of how the web player looks and functions, check out this link: https://ift.tt/AJqzW6a... I believe Oration can significantly benefit those who prefer or require alternative learning formats. We're committed to enhancing the app's functionality and user experience, so feedback and constructive criticism are always welcome. Thank you for considering Oration, and I hope it proves to be a valuable tool for you or someone you know. https://oration.app February 9, 2024 at 09:21PM

Show HN: A platform for remote piano lessons based on the Web MIDI API https://ift.tt/ZROMUDQ

Show HN: A platform for remote piano lessons based on the Web MIDI API I'm building a video conferencing app designed to facilitate better remote piano lessons. My hope is to solve a lot of the challenges piano tutors and new students deal with when taking lessons through Skype/Zoom. It leverages WebRTC's data transmission to send media, MIDI state, and (eventually) send sheet music files and other musical data. I'm surprised with how well the MVP has worked and would love to hear any feedback or suggestions! https://ift.tt/d6ySvZV February 11, 2024 at 05:20AM

Show HN: Mukette, a Markdown Pager for Unix-Based Systems https://ift.tt/kzCdpR7

Show HN: Mukette, a Markdown Pager for Unix-Based Systems I really apologize if I am submitting this twice. I am new to these fora. I just discovered Show HN. The other thread did not have Show HN so it did not get any traction. This is a useful little tool so I guess people will like it. You're eithre like me, and do all your work in the terminal emulator. If they literally replace my displays with a VT100 I won't complain (but have to watch Youtube on my phone -_-). The other kind of use is someone who uses X (I know emulators are X too!) extensively, and only often needs to use the terminal This can be useful for both groups. Imagine you wanna read the README.md file of a repository. This happened to me what I wanted to read PackCC's REAMDE. And I had to do a pipline from Pandoc to Philadelphia! This nifty little tool will page the markdown file. I want to improve it in the future. I have made some leeway to adding more features to it. I want people to execute the code listings (in a safe environment) by navigating to them. It's all right these in the code, I just got tired of picking at this like an old wound and releassed it. It's been rand through ASAN and Valgrind. Some errors were fixed. If anything remains that I missed please tell me. I always initialize pointer ssto NULL so it should not complain much? Anyways thanks. https://ift.tt/qoazc3v February 10, 2024 at 05:45AM

Show HN: AutoBashCraft – a tool for automated Markdown screencast generation https://ift.tt/XLHDF48

Show HN: AutoBashCraft – a tool for automated Markdown screencast generation Hello HN, Around New Year's I started a personal project called AutoBashCraft (ABC), aiming to simplify the creation of screencasts from bash code blocks in markdown files. I needed to create a lot of markdown files explaining workflows and code. I wanted to make the text-heavy files more interesting and thought of screencasts. There are many great tools to record terminal sessions. Then I found the asciinema-rec-script ( https://ift.tt/6vKPAG0 ) by Chris Ottrey that creates screencasts of bash scripts that look like a record of a terminal session including typing out the commands. I wanted the markdown files to be the same documents you would use as training or documentation material so I picked HTML comments to mark the codeblocks that are supposed to be executed. It would then execute the commands and save the screencast next to the markdown file in an asset folder so they can be easily embedded just under the codeblock. I went on from there and more commands were added such as 'create' to create a file with the contents of the codeblock, 'browse' to create a screenshot of a website, 'spawn' to spawn a background process, 'snapshot' to create a docker container of the current environment state, 'init' to initialize a new environment e.g. from a snapshot created in another file and 'config' to change configuration for the following commands. ABC is very much a work-in-progress and a proof of concept at this stage. I am also thinking of adding an editor to create a similar experience to jupyter notebooks, with automatic snapshots between each command in dev mode. There is so much work left to be done but for now I am back at my day job. The repository includes some examples that also work as (currently manually executed tests) including more complex workflows like automating MBTiles generation and usage or integrating private GPT, showcasing what I hope it can become. Running it is as simple as using NPX, with Docker and Node.js being the only requirements. Please only run your code or code you trust (esp. with docker activated). I later realized it also serves as a validator for the accuracy of instructional content. It happens so often that training material is missing important steps and it is very frustrating for beginners to follow a guide step by step and it just won't work. I'd be incredibly grateful if you could take a moment to check it out on GitHub, give it a star if you find it interesting, and maybe even contribute or fork it. I'm looking forward to your feedback and suggestions. Let's make something great together!

Show HN: Trelent - Your team's fully-encrypted AI assistant Wish you could use ChatGPT at work? You know that AI would boost your team, but your boss is (rightly) worried about data leaks. Meet Trelent, your team's fully-encrypted AI assistant that ensures nobody outside your team can see company data. ChatGPT and others have content-logging enabled ("abuse monitoring") and don't let you control your data. Your intellectual property is at risk. Many of you can't use ChatGPT or similar tools at work because of corporate policy on this basis. We solved that by negotiating with AI providers to disable content logging, then we let you encrypt the persisted chat data in our database with a key you control (BYOK). That means you get state of the art AI assistance (GPT-4 and Mixtral to start), without the security risk. Single-tenant and on-prem deployments are available for those who can't have company data leave their network. If that sounds like you, please reach out to us[1]. Otherwise, our public-cloud product that you can use today still has the content logging disabled and field-level encryption using a key in our control.

Show HN: Forum where posts slowly disappear unless interacted with https://ift.tt/QfAGsxe

Show HN: Forum where posts slowly disappear unless interacted with I'm always nervous to post online (this is my very first HN post), so I built an anonymous forum where posts are automatically deleted after 24 hours. Every upvote or comment resets the clock. Some things I like about this concept: - The sheer volume of information on the internet is overwhelming - disappearing.chat keeps that volume low - Unpopular content slowly fades away, so you can visually watch bad takes disappear - Content is always fresh because even popular things will eventually stop getting interaction - Takes the pressure off that your content is going to stick around forever fwiw this just started as a toy project to play around with the Next.js app directory, Tailwind and deploying to Vercel, but I figured I'd get it fully functional and share it. https://ift.tt/tiIDTrz February 6, 2024 at 11:14PM

Show HN: A Python PDF Form Library https://ift.tt/OmjNqdt

Show HN: A Python PDF Form Library Hi HN! I have a project that I have been working on for three years that I’d love to show you today called PyPDForm ( https://ift.tt/6oI1WgK ). It is a Python library that specializes in processing PDF forms, with the most outstanding feature being programmatically filling a PDF form by simply feeding a Python dictionary. I used to work at a startup company with Python as our backend stack. We were constantly given paper documents by our clients that we needed to generate into PDFs. We were doing it using reportlab scripts and I quickly found the process tedious and time consuming for more complex PDFs. This is where the idea of this project came from. Instead of writing lengthy and unmaintainable reportlab scripts to generate PDFs, you can just turn any paper document into a PDF form template and PyPDFForm can fill it easily. On top of the GitHub repo, here are some additional resources for this project: PyPi: https://ift.tt/iStXgTp Docs: https://ift.tt/0icnj8z A public speak I did about this project: https://www.youtube.com/watch?v=8t1RdAKwr9w I hope you guys find the library helpful for your own PDF generation workflow. Feel free to try it, test it, leave comments or suggestions, and open issues. And of course if you are willing, kindly give me a star on GitHub. https://ift.tt/6oI1WgK February 4, 2024 at 06:55AM

Show HN: An open source performance monitoring tool https://ift.tt/dzBWHMj

Show HN: An open source performance monitoring tool Hey HN. We’re Jay and Vadim from Highlight.io ( https://highlight.io ). We’re building an open source [1] monitoring platform for web applications. Today we’re excited to be sharing a performance tool we’ve been working on, which helps you inspect the latency of code execution from the client to the server. As engineers at past startups, we often had to debug slow queries, poor load times, inconsistent errors, etc... While tools like Jaegar [2] helped us inspect server-side performance, we had no way to tie user events to the traces we were inspecting. In other words, although we had an idea of what API route was slow, there wasn’t much visibility into the actual bottleneck. This is where our performance product comes in: we’re rethinking a tracing/performance tool that focuses on bridging the gap between the client and server. What’s unique about our approach is that we lean heavily into creating traces from the frontend. For example, if you’re using our Next.js SDK, we automatically connect browser HTTP requests with server-side code execution, all from the perspective of a user. We find this much more powerful because you can understand what part of your frontend codebase causes a given trace to occur. There’s an example here [3]. From an instrumentation perspective, we’ve built our SDKs on-top of OTel, so you can create custom spans to expand highlight-created traces in server routes that will transparently roll up into the flame graph you see in our UI. You can also send us raw OTel traces and manually set up the client-server connection if you want. [4] Here’s an example of what a trace looks like with a database integration using our Golang GORM SDK, triggered by a frontend GraphQL query [5] [6]. In terms of how it's built, we continue to rely heavily on ClickHouse as our time-series storage engine. Given that traces require that we also query based on an ID for specific groups of spans (more akin to an OLTP db), we’ve leveraged the power of CH materialized views to make these operations efficient (described here [7]). To try it out, you can spin up the project with our self hosted docs [8] or use our cloud offering at app.highlight.io. The entire stack runs in docker via a compose file, including an OpenTelemetry collector for data ingestion. You’ll need to point your SDK to export data to it by setting the relevant OTLP endpoint configuration (ie. environment variable OTEL_EXPORTER_OTLP_LOGS_ENDPOINT [9]). Overall, we’d really appreciate feedback on what we’re building here. We’re also all ears if anyone has opinions on what they’d like to see in a product like this!

Show HN: Vibescape – Immersive Meditations for Apple Vision Pro Hey folks, back with a new release! I'm very happy to share with you my day one immersive meditation app for Apple Vision Pro. It's called Vibescape, and it's available today! This first version features a series of meditative vignettes, shot on Spatial Video, on location in the Pacific Northwest. Dramatic Douglas Fir stands sway in a winter storm. Ripples undulate in pools of water in a 19th century quarry. Icy-ASMR in a fern covered forest. You can also set up a custom meditation timer, either silent or from a selection of deep ambient noise, and transport yourself to truly unique immersive environments. It was a lot of fun building this – from braving an ice storm to capture these vignettes for you, to developing something once again for a brand new platform. It was almost 15 years ago I took that leap when creating Polychord for iPad. Similar vibes. Hope you check it out, and let me know what you think! Lots planned for version 2, but hearing what would excite you the most would make a huge difference. https://ift.tt/IpE1HZP February 2, 2024 at 10:02PM
