Show HN: Fern, a language for defining REST APIs that compiles into OpenAPI Hi HN, this is Danny, Deep, and Zach. We built Fern after our previous ed tech startup failed. We were frustrated with how much time we spent writing “API code” instead of working on the actual product. We tried to use OpenAPI but we were underwhelmed - the generated code wasn’t idiomatic and it still required manual work (custom templates, scripts, manually publishing SDKs to registries). The Fern compiler takes your API as input and invokes generators that output things like: SDKs, server code, a Postman collection, and an OpenAPI spec. Some technical highlights about the compiler + generators: - The compiler (available as a CLI) handles syntactic + semantic validation. It also includes a linter that encodes best practices. If your API Definition compiles, you can have high confidence that the SDKs will generate correctly. - After all the parsing and validation, the compiler outputs an intermediate representation that gets handed off to the generators. This prevents each generator from re-implementing the same parsing and validation logic. - Each generator is implemented in the language it is targeting - e.g. the Python generators are written in Python, the TypeScript generators are written in TS. It makes the SDKs more idiomatic because every programming language generally has the best tooling/libraries for generating code in itself. We also think it’ll make community involvement + contribution easier. - The generators can output the code to disk, but also push the code to a Github repo and publish the SDK directly to registries (e.g. npm, Maven). We are looking for devs to use Fern for API development. If you have any feedback about the process, compiler, or the generated code, we’d love to hear it.

Show HN: Syncthing-map – a utility to map syncthing devices and folders If you use the excellent Syncthing[1], you may quickly be lost in the various shares between devices. I was. This was the trigger to write a small application that creates a map of your devices, their folders, and how each is shared. It is directly based on the configuration file of each device. The stable version[2] generates a HTML file you can render in a browser to show the map (based on mermaid.js[3]). I just released an experimental feature[4] that starts a web server which will dynamically create the map based on configurations shared by the devices. Binaries are available as well[5]. I would be glad to hear any comments or advice (I am an amateur developper). Thanks! [1] https://syncthing.net/ [2] https://ift.tt/jCbLkTf [3] https://ift.tt/HpcvTgZ [4] https://ift.tt/BWn0FH6...

Show HN: Ecode – A minimalist and fast open-source code editor Hi HN! I've been working on a code editor and I think that it's mature enough to catch some interest. It's using a custom GPU accelerated GUI written in C++. Currently implements some interesting features: LSP, terminal, auto-completion, linters, formatters, custom keybindings, plugins and more. It's a hobby project but still intends to be an alternative to other popular code editors like Sublime, Kate, Lapce, Lite XL (and takes inspiration from them). The project was born as a playground for the GUI I'm developing (eepp GUI) and is advanced enough to currently be my main code editor, but it's a work in progress, and many features are still pending. Some minor hints on how to use it: Folders are used as project (and .gitignore is used to ignore files) The wheel icon on the top-right has all the options you need (Ctrl/Cmd + M to show). Some keybidings to navigate any project (navigation is keyboard driven): Ctrl/Cmd + K = Locate Files Ctrl/Cmd + Shift + F = Global Search Ctrl/Cmd + Number (Go to tab #) https://ift.tt/A7wOYps January 10, 2023 at 10:51AM
Show HN: PipeScore – FOSS Bagpipe Notation Software I've been working on some version of this since May 2019. It is a web app that allows writing out music for the Highland bagpipe. While it uses the same notation as normal music, bagpipe music tends to have a greater focus on gracenotes (embellishments). Most music software does not deal with this very well (e.g. MuseScore just displays a list of every single possible embellishment, of which there are hundreds [1]). PipeScore instead takes advantage of the fact that the form of many embellishments is dependent on the notes adjacent to it, allowing it to reduce the number of options down to just 13.

Show HN: Tortoise TTS as an at-cost open-source pay-per-second API Tortoise TTS is the best TTS available today. We built an open-source, at cost, pay per second API for it. The quality of intonation it generates is unparalleled, and we hope our at-cost API will make it easier for people to build on top! This allows folks to run via a single API call - it costs $0.03/query. The WAV file is downloadable, we apply no restrictions. We're open-sourcing all our work — we made Tortoise run 30% faster, and have more improvements coming. If you're keen to contribute we can help with ideas, pointers, compute and data; just DM us. Our fork with the improvements can be found at https://ift.tt/usRGhbj . The deployment code can be found at https://ift.tt/SqRZb10 . There are already great alternatives for using : i) @mdnest_r's awesome Huggingface Spaces, ii) original Google Colab, iii) host it yourself. Our work should accelerate those who need an API, don't want to spend time/$ hosting and need a scalable infra backing them. We're especially excited about combining text-to-speech with content generated from LLMs, and about how it fits into video creation tools. Tortoise in its current form is also inaccessible to non-technical users, which is why we are also providing a simple UI on top (also "at-cost"): https://tts.themetavoice.xyz To use, generate an API key on https://tts.themetavoice.xyz and call via POST request. Or use the web UI. Or run your own deployment. https://twitter.com/vatsal_aggarwal/status/1612536547248836608 January 10, 2023 at 01:35AM
Show HN: I asked ChatGPT to convert a Chrome ext to a Firefox ext I told it to create a virtual machine first: I want you to act as a Linux terminal. I will type commands and you will reply with what the terminal should show. I want you to only reply with the terminal output inside one unique code block, and nothing else. Do no write explanations. Do not type commands unless I instruct you to do so. When I need to tell you something in English I will do so by putting text inside curly brackets {like this}. My first command is pwd. Then I told it to create a python script to do the conversion: {Create and write to the filesystem a python script called convert.py that takes a URL as its first argument. The URL is a chrome extension. The script then converts the extension to a Firefox extension and saves the result in a directory called "res". Make sure the script works with an actual URL to a chrome extension on the Chrome Webstore. It requires you to possibly download the extension first from the URL. Also make sure the generated Firefox extension meets all the requirements and the Chrome to Firefox conversion takes place for all assets in the extension, it includes the content scripts, etc. Only print done to the terminal here when finished.} Then ran it with this URL (URL to Google Translate Chrome ext): python convert.py "https://ift.tt/YFHC5ce" It actually created a zipped Firefox extension with the manifest file converted correctly, etc. January 9, 2023 at 09:50AM
Show HN: Have voice-only virtual coffees with fellow HN'ers I'm running several voice-only virtual coffee events on the Discord server in the URL, only for today. The rules are pretty simple: 1. Wait for the "event" to start (see times at the end) 2. If there are no tables with 1 participant, join any one. 3. If there is a table with 1 participant, join that one. 4. When the event ends, all the voice channels are deleted and you have to wait till the next event starts. I initially wanted to build my own web app but then I realised it would be so much easier to just leverage Discord's infrastructure. I also built a bot in a couple hundred lines of Go code (love the language!) to bulk create/delete voice channels. I intentionally left it super basic to validate if there's a need. I personally would love to have virtual networking events, but then again I know I'm somewhat odd as I come from a sales background. If you're interested/want to take part in more of these events, check out my profile where I have some contact options.

Show HN: I Market-Make AWS Cloud Contracts to Save Companies $40M+ Hey HN: Kaveh here, the founder of https://www.usage.ai/ We help companies drive down AWS EC2 spend by buying and selling 3-year no-upfront reserved instances. Why? Because there's almost no liquidity on the AWS EC2 RI Marketplace and it can take a while, if at all, to sell an RI if you need to stop using one. Previous to founding Usage, I worked at JPMorgan Chase as a summer analyst. Here's how it works: We are typically brought in by a DevOps manager to cut AWS EC2 costs. The app is entirely self-service and the savings are generated automatically, typically we do this live on a call. On average, we reduce AWS EC2 spend by 50% for 5 minutes of work. To reduce by 50%+, we've built a pool of reserved instances that's shared across our pool of customers. When a customer scales up their EC2s, Usage buys RIs. When a customer scales down their EC2s, Usage sells RIs. At this point, we've saved companies tens of millions of dollars in spend and have a lot of liquidity, so we take on very little risk. We make money off of a 20% Savings Fee. Happy to chat directly kaveh@usage.ai Have you experienced any issues with managing your company or organization's AWS expenses? We'd love to hear your feedback and ideas! January 7, 2023 at 09:15AM
Show HN: ACOS: Build and share competitive turn-based browser games Hi everyone, This is a little tech demo I've been working on the past 2 years. It's been up for 1 year now, and has since had a few major updates. I have a soft spot for games with ranking systems, and I wanted an easy way for developers to create games with the competitive element abstracted away. The current games are built with ReactJS, so it's pretty easy to onboard if you are a web developer. All games developed for ACOS come with these features: - Real-time turn-based for browser - Simulator for game development - Client / Server architecture - Easy multiplayer with simple JSON game state update - Single player, Team-based, Battle Royale, and Free-for-all games supported - Matchmaking for Rank / Casual play - Room Scoreboard - Game Replays of every match - Error Logs - Global Rankings - Global Top Scores - GitHub Integration with acosgames organization - Discord Integration for matchmaking / game events - Simple deployment and version management It's a ridiculous endeavor, but I'd like to invite the world to my playground and help me drive features and technology forward. I may allow AI bot battles in the future against any of the hosted games, but I will prioritize based on the will of the people.

Show HN: I spent 2 years building Tablane as a 17-year-old Hi HN community, I'm Marcus, a 17-year-old Software Engineer from Germany. For the past two years I've been working on Tablane [0]( https://ift.tt/iOk3taX ) a task/project management tool, with features like: - Collaborative Editing (google docs) - Optimistic updates with RTK Query - Realtime sync with Socket.io - An awesome design Let me know what you think! Ask me anything! How I got here: 2020: I was developing a TTT [1] (Trouble in Terrorist Town) plugin for my minecraft server, when I started to require a project management tool to keep track of the features I wanted to implement, originally I used a text file, but after some time I started using products like ClickUp and Monday. But not long after I hit several paywalls for features that I wanted to use (Custom Status, Limited Number of Boards, ...) Soon after Tablane (originally task-board) was born. I started building the website using plain HTML, then found out about React and completed Colt Steele's "Web Developer Bootcamp" [2] and "The Modern React Bootcamp" [3] and started re-writing Tablane in React, and started adding feature after feature. Now I am about to finish Highschool and originally I thought about applying to college and spending another 3-5 years there, but after the positive feedback I got on a three month internship I did at ContentPepper, and seeing how my own projects developed, I decided to look for open Developer positions, to work with a team of experienced developers so I can learn even faster.

Show HN: Ello (YC W20) – AI-reading tutor for kids that works with real books Hi HN, We’re Elizabeth, Catalin, and Tom - the founders of Ello ( https://ift.tt/fqCFK5v ). Ello is an AI-powered app that mimics the one-on-one interaction of a reading tutor by listening to, encouraging, and coaching kids grade K-3 as they read out loud from a real book. We posted on HN back in 2020 when we launched Trustle, a company designed to pair families with dedicated experts in child development. We learned from that experience that parents don’t want a consultant, but they do want actual help with specific challenges—one of the biggest being reading. Prior to COVID, 65% of 4th graders in the U.S. were reading behind level. The most recent National Assessment of Educational Progress report revealed that reading levels have dropped even further, to the lowest level since 1992. These disheartening statistics reinforce something we learned during our time at Trustle—of all the pain points parents face in raising children, reading can often be one of the most critical yet most difficult to address, especially if the child doesn’t like to read. In an effort to help reverse this trend, we used advances in speech recognition - driven by self-supervised learning - to create a virtual experience designed to provide effective reading support. It's no substitute for attention and coaching from a caring adult, which is obviously what kids really need, but unfortunately that is not always available. If every child had consistent access to 1:1 reading support and every parent or caregiver had the time, language skills, and confidence to help their children learn to read with no outside assistance, then there would not be a need for a technical solution. Unfortunately, we know not every child has this access, and many parents are looking for extra support. That's why we've built Ello. If you look at a great teacher or parent working with a child, they are talking to each other. Ello uses a speech recognition model that listens to what a child is saying and provides the appropriate phonics based coaching, as well as commentary and help. As a child reads across the page of a physical book, the Ello app tracks the child’s progress and picks up when they miss a word or get a word wrong and then steps in just like a good reading coach would. One criticism that we’ve heard since launching is that we are trying to replace the sacred role of a parent teaching their child to read. We say, “Not at all!”. Ello can serve as a resource for every type of parent without being a “replacement”, which is impossible in any case. We’ve had most success with children who are reluctant readers. Ello provides a fun environment to practice reading without the pressure of an adult watching you. We’ve seen kids who flat out refuse to read start to enjoy reading in a short period of time. We are highly privacy oriented; unlike most apps relying on speech tracking we can work completely on device with no internet and no audio data shared back with us. We launched in early in 2022 and have come a long way since then. The model works like this: we mail customers five books and a prepaid return shipping label every month. At the end of the month you mail the books back or keep as many as you want for an additional $5 apiece, and then we mail you next month’s box. Our reading specialists help determine the appropriate reading level for every child and make sure that we are sending books to match. Right now we support roughly K through 3rd grade, although Ello can be effective for some Pre-K kids as well. We know there are many parents on HN, including those with young children. We would love to hear about your experiences and needs around your children’s reading journeys and your perspective on how something like Ello might help. Or, if you’re in the US, give us a try - you can get a free month with code ellohacker. And of course we welcome any feedback, questions, and ideas!

I found myself (on old account) reflexively checking my Karma score and found myself responding emotionally to it. I do not like this. Positive reinforcement can be a dangerous thing! And negative reinforcement make me feel a bit crap. I'm going to post what I think is the right thing, votes be damned! However I do see the use of downvotes for getting rid of stupid comments and spam as a good thing. I see the use of down/upvotes for political ideologies as a bad thing. SO, I simply used uBlock to permanently block "Karma" across HN topbar. Simply go to uBlock icon, press Element Picker Mode (the eyedropper), select the Karma number, and select the Create button. Done. January 2, 2023 at 07:39PM
Show HN: Detecting collision between 500k circles below 5ms Heya. I created a flexible collision engine for broad detection in C that's also pretty fast. Personally that's my best, so I wanted to show it here. Although... still not as fast as DragonEnergy's one that supposedly handled millions of agents bouncing off each other every frame on an old i3, haha. I hope I get better at this! He set the bar pretty high for me. I was considering including some small function that tries finding the nearest entity, although I think it might be better to simply use query for that matter. Perhaps in the future I will get a good idea of how to do that more efficiently. This is not a clickbait. Although generally you also call other functions in a tick, a collision check between 500,000 circles ("circles", not "squares", because distance is checked and forces are applied based on the angle between) is done below 5ms on not really that demanding hardware. I achieve lower times than that on my budget laptop, slightly more on my PC (yeah, weird). The total time spent in a tick is 3-4 times that. https://ift.tt/StpRAgP January 2, 2023 at 01:38AM

Show HN: I made a simple, open source, chromatic tuner mobile app I'm a musician by night, software developer by day, and one of the minor frustrations I've always had was trying to find a simple tuner app for my phone. Looking at both the iOS and Android app stores, you'll find a lot of the top tuner apps are rather bloated with ads or subscription callouts. I thought I'd create a dead-simple minimalistic mobile chromatic tuner the way I would like it - open the app and tune my guitar. My work is in web with NodeJS and React, so I chose React Native since it was the easiest to understand coming from React. Flutter was also an option since the company I work for has a team working in that, but I thought it would be a bit too much effort to learn Dart. I learned a bit more about React rendering with this project as well. The main issue I had was trying to have a React state variable be constantly updated with any frequencies detected from the mic input, but that ended up causing substantial slowdown due to so many rerenders, so I opted to use a React ref to maintain any detections, and then only update the React state when there was an actual note. I feel like sometimes the UI has trouble updating occasionally when my iPhone is in battery saving mode, which I guess might be related to throttling the audio sample rate somehow, though I'm not entirely sure. Friends and family haven't noticed this, so it may be due to my old 2016 iPhone SE :P.

Show HN: lambdaprompt – build, compose and call templated LLM prompts For the past few months I've been building a lot of things with LLMs (GPT-3, Codex, etc.) as I've been trying to push them to their limits (especially towards applying them to the tabular data domain) When working on this, I've found there are some common patterns for solving problems (templating, chaining, functional-programming style operations, etc.) As I've iterated, I've come to believe that a functional style interface is likely going to power a new wave of systems I'm calling "prompt-machines"(systems where the core new unit of work is a "named" LLM prompt, extending the "function" concept). Additionally, in order to make the code capable of meta-prompting (where the LLM can write its own templated prompts), I aimed to make the interface and library as simple and lightweight as possible. I think I've achieved my goal, so I'm releasing the library to share with others! I mainly use lambdaprompt in two main ways: (1) to quickly try out "map" applying a LLM prompt against multiple inputs, to see how it behaves on a fixed set of inputs (2) to quickly iterate on a prompt-chain (taking the output of a prompt, and passing it to other prompts) to create complex behavior. An example of (2) that worked quite well is a Text-2-SQL prototype: It generates multiple SQL options, then executes each against the database (if it errors, asks `Codex-EDIT` to fix the errors and retry), then takes the most "consistent" answer as the valid answer. Simply by adding this prompt-chain on top of codex, we saw an improvement from ~75% to ~85% on a spider Text-2-SQL benchmark (On just a small sample of N=200). To increase usability it also ships (extras) with a fastapi app that registers any defined prompts as endpoints directly, and hosts the functions to be directly callable via HTTP-GET requests. This makes it easy to build client-applications off of these prompts, while allowing the prompt itself to be arbitrarily complex (composition of prompts) I hope you enjoy using it! Also, I'm super curious to hear if anyone else has been thinking about LLMs (composing them, building interfaces to them, etc.) in similar ways and what learnings have been (even if not though this library) https://ift.tt/hmWUOxM December 31, 2022 at 02:43PM
Show HN: RSS Brain I wrote an RSS reader called RSS Brain recently. The motivate is the current RSS readers either don't sort articles by priority, which makes it hard to read posts from HackerNews and Reddit, or sort it with some "smart" algorithm which I don't trust. I also like the Google News feature that can show related story from different source, but the sources are not configurable and the algorithm is not transparent either. So with RSS Brain, I implemented these features: * Recommend related articles from the feeds of your choice. It's backed by ElasticSearch and the algorithm is described on RSS Brain's website. * Option to sort articles by upvotes and time. The algorithm is similar to the old Reddit and you can find it on the website as well. * Save search terms into folders so you can filter the articles. I've been using it for a while and found these features very helpful. So I want to share this on HackerNews. The frontend is written in Flutter so it has cross platform clients, even though the web version don't feel very "web native" because the level of Flutter web support. I guess only time can improve that. I don't have enough hardware to scale it up so it's currently in subscription mode to limit the users. I'm going to open source the code (maybe non-commercial license) once I think it's ready so you can host it by yourself. It's still in early stage and haven't been tested by a lot of people. So any feedback is helpful. Thanks! https://ift.tt/sybih2g December 31, 2022 at 12:43AM

Show HN: Zcached, in-memory key-value cache wire-compatible with memcached zcached is an in-memory key-value cache exposing a memcached ASCII protocol-compatible interface, built on pluggable cache engines like Ristretto and freecache [0]. It's not performance-competitive with memcached, especially at higher thread counts. That said, it achieves about 1.1M ops/s, but at significantly higher P99 and P999 latency (as measured by memtier). See [1] and [2] for benchmark results from my 7950x-based workstation. Disclaimer: This is a hobby project created for fun while hacking over the holidays. zcached is not a commercial product and never will be. Don't use it in production; consider this a technology demo more than anything.

For me, the precipitation timeline was a view I was heavily relying on for everyday activities and planning. I had not found any replacement from the various weather apps. When I found pirateweather.net as a backend API, it gave me the motivation to put the pieces together and get back the experience I enjoyed. I then added more functionalities that I think was missing from the website such as a weekly chart view. I've been using the website reliably over christmas holidays. Hope you enjoy it too!

Show HN: TapTab – Tab switching web extension for Safari I like the tab-switching behaviour in Chrome/Firefox and wanted Safari to have something similar. Another wish of mine was for it to be a web extension that feels native to the browser vs an app extension that looks out of place. I posted a while back on HN to see if other people feel the same and the response was very positive : https://ift.tt/CSsLRia Say hello to TapTab : https://ift.tt/dFR7Hfw... TapTab feels right at home in Safari and is loaded with features to improve how you interact with tabs. You no longer have to miss the native tab-switching functionality that you love in Chrome/Firefox. I launched the app a few days ago, and the response has been great. Some of the features that users have been loving : - Keep your hands at the keyboard: navigate all tabs without your hands leaving the keyboard. - Fuzzy Search: Search through your tab titles and URLs at lightning speed. - Switch to previous tab: Comes with a handy shortcut to go back to the previous tab. Finally! - Dark Mode: The extension feels right at home in Safari. - Multi-Window support - Pin/Mute/Close tabs right from the extension. The app is written in ReactJS (apart from the very minuscule bit of Swift you have to write for using it as an extension in Safari) and uses Tailwind for design. If you are one of the dozen people like me who use Safari, let me know how you find it. I would love to hear if there are any features that would make it a better fit for you. I have a few things on my radar gathered from talking to users like an iPad version, custom shortcuts, etc. If you find the extension useful I would love it if you vote for it on Product Hunt to get this in front of a few more eyeballs : https://ift.tt/iAhwBYc Thank you! https://www.taptab.dev December 24, 2022 at 06:35AM

Show HN: Box4D – 4D physics demo using Rust and wgpu This is a little physics toy I've been working on off and on for a while. I originally planned on making a more fully featured game of some sort (I suppose I still may some day), but it turns out that writing interesting graphics and physics algorithms is more compelling than the hard work of polishing an actual product. Who knew? While there are plenty of good guides for 2D and 3D graphics and physics, there's not much out there for 4D. In hopes of alleviating that, the code here is arranged such that the commits are more or less a step-by-step guide, with comments for the interesting or tricky parts. While I don't think I came close to the simplicity or clarity of Box2D Lite, I hope it can serve as a useful example to anyone interested in 4D rendering and physics. https://ift.tt/iXImGJM December 24, 2022 at 12:00AM
Show HN: Metriport – Open-source universal API for health data Hey HN, we’re Colin and Dima, founders of Metriport ( https://metriport.com/ ). We help digital health companies access and manage user health and medical data, through an open-source and universal API. Today we're launching our open-source Health Devices API, which allows companies to gain access to their users’ health data from various wearables, RPM devices, and mHealth apps. You can check out the public Github repo here: https://ift.tt/PJjSKke For developers in the health data space, building integrations to various data sources is a huge pain, as it means wrangling different data formats, gaining access to the APIs in the first place, and ultimately spending precious developer resources building out data pipelines. We solve this pain for you through our open-source API, which is quick and easy to get started with (see: https://ift.tt/tVO4rvB... ). Out of the box, our Health Devices API supports integrations with Fitbit, Oura, Whoop, Withings, and Cronometer. We plan to add many more, including Garmin, Apple Health, and Google Fit in the near term. We work closely with our customers, so if there’s an integration you need, we’re more than happy to build it into our API. Because we’re open-source, you can also fork our code and build your own custom integrations. Getting started is simple. To start getting data from your users: 1) Create a developer account and generate an API key: https://ift.tt/7n3kRly 2) Set up our client on your server and initialize it with your API key: https://ift.tt/tVO4rvB... 3) Link the Metriport Connect widget into your app. This pre-built widget makes it easy for your users to connect all their data sources into your application. Now you’re ready to start accessing your users’ health data from their sources they’ve connected. We also offer a hosted SaaS solution with usage-based pricing, with no minimum platform fees. We believe this will open doors to a wide range of early stage companies and help drive innovation in the digital health industry. While we’re excited to be launching this product today and be the first open-source Health Devices API of its kind, we’re also really looking forward to sharing our Medical API with you in the coming months. You can find out more about that here: https://ift.tt/ycWKXJr We can’t wait to see how this API is used and what it helps companies develop. Please don’t hesitate to reach out if you have any questions, and happy developing! https://ift.tt/PJjSKke December 23, 2022 at 03:39AM

Show HN: How to use ChatGPT+ARKit to script experiences with natural language Video demonstration: https://youtu.be/bJFa5HOmhl4 I created a demo involving ChatGPT, OpenAI's Whisper running on-device for speech-to-text (because why not?), and ARKit. By defining a custom JavaScript environment with JavaScriptCore and describing it to ChatGPT, I was able to get it to produce functioning scripts that instantiate and manipulate 3D objects. Sketchfab is used to import 3D assets on the fly. Google Poly had a much better catalog of assets for this sort of thing but sadly, it's no longer available. The README.md describes how it all works but the gist of it is that user prompts are wrapped in a larger prompt that describes the environment (i.e., which functions are available to use and how they work) and constraints. The code is then executed directly. Assets for objects are fetched as needed by searching Sketchfab. https://ift.tt/70VKLzj December 21, 2022 at 11:51PM
Show HN: Yahtzee and Poker and Cosmic Horror = Pine Tar Poker I'm excited to launch today! Pine Tar Poker is a yahtzee-inspired poker game with just a touch of cosmic horror for iOS and Android. I started working on this idea last January by making a paper prototype: a simple printed score sheet I could use with a real deck of cards. I had some fun with that, so I brought it into Unity and kept expanding on it over the last 11 months during nights and weekends. It's tough for me to stay motivated on side projects and see them through to release, but the act of shipping something is so fulfilling that it's usually worth the pain. For Pine Tar, I stretched myself in the narrative department by adding a bit of a Lovecraftian tone to what would otherwise be a Western saloon setting. One thing that kept me motivated during development was seeing my dad get hooked on the card game. He'd text me when he got his first royal flush and when he prestiged the score sheet -- he got every hand type in one game! He has amassed so much in-game cash, I think I need to expand the number of digits I show there! If you get a chance to try it, let me know what you think!

Show HN: The easiest way to run a brainstorm, supercharged with A.I Hello friends! We've been working hard on building Mimosa, and would love for you to try it! No signups required. Facilitating brainstorming sessions can be a challenging and time-consuming task. It's difficult to keep everyone on agenda, engaged, and contributing. So we've built Mimosa to be the easiest way to facilitate a brainstorming session. Imagine if a "digital whiteboard" and a "trello board" had a baby, but built with all the best practices of professional facilitation. With Mimosa, you can minimize bias by allowing team members to contribute anonymously before revealing their ideas. This ensures that everyone has a fair chance to share their thoughts and ideas without fear of judgment. Once the brainstorming session is complete, you can easily view and export the final results. This allows you to keep track of a meeting's effectiveness and share it with stakeholders. But the real game-changer is our AI Brainstorming features and it's ability to turn your 1x team into a 10x team. It help generates and collaborates with you in your brainstorming session to help you come up with more and better ideas. We're both scared and excited to hear all your thoughts, HN! :) Please do let us know any features or improvements you think we should make to help you in your meetings. https://mimosa.so/ December 17, 2022 at 12:11AM
Show HN: AI Avatar Image Generator Based on Other AI Images An AI Avatar image generator that creates images of you based on other AI created images. The popularity of the recent AI Avatar image generator apps sparked some interest of mine in the area. After playing around with a few AI Avatar image generators, some of which generate pictures of you based on pictures you upload and prompts you write, I thought, wouldn't it be much easier, instead of writing out prompts, to just select another image which you want your generated image to be based on. The image the user selects is actually another AI generated image, so we know the prompt used to generate it. So prompt writing is abstracted away from the user, and instead they can search for images and click on ones they like. Backend of the application currently uses Astria AI for the image model training and generation, and uses the Lexica API for getting lists of AI generated images and their prompts. https://ift.tt/nrBtbdp December 15, 2022 at 08:19PM

Show HN: Web search using a ChatGPT-like model that can cite its sources We’ve trained a generative AI model to browse the web and answer questions/retrieve code snippets directly. Unlike ChatGPT, it has access to primary sources and is able to cite them when you hover over an answer (click on the text to go to the source being cited). We also show regular Bing results side-by-side with our AI answer. The model is an 11-billion parameter T5-derivative that has been fine-tuned on feedback given on hundreds of thousands of searches done (anonymously) on our platform. Giving the model web access lessens its burden to need to store a snapshot of human knowledge within its parameters. Rather, it knows how to piece together primary sources in a natural and informative way. Using our own model is also an order of magnitude cheaper than relying on GPT. A drawback to aligning models to web results is that they are less inclined to generate complete solutions/answers to questions where good primary sources don’t exist.

Show HN: We built a Slack-based workflow assistant for devs & their teams Hey, Nir here - co-founder & CEO of Zigi. It’s a personal workflow assistant that was built for devs and their teams to automate non-coding tasks, giving updates and quick actions only on what’s relevant. It works by examining your activity in Jira and GitHub (more systems being added soon) to understand your workflow, creates context out of all that information, and offers you actionable assistance from Slack. Zigi is customiazible. We’re building it to match every R&D persona so you can tailor the messages and assistance you get to meet your specific needs. Like if you’re TL, you can get daily updates on the progress of your team’s sprint or as a QA, you’ll be notified as soon as ticket is ready for testing. We’re developers who are used to managing big R&D teams and over the last few years, we have seen dev change drastically. There’s so much overhead on top of coding, more dependencies, multiple tools, that developers are overloaded. And now, the world has changed to make teams are remote and in different time zones, which just makes everything more complex. Zigi takes a new approach to driving productivity, while keeping devs and their teams happy. It provides hands-on help with personalized automation, so we can manage our day-to-day tasks with minimal distractions and maximum focus. Some things to know about Zigi: you don’t need to set it up or run any config; it’s customizable to your needs; it only needs user-level permissions and doesn't read or scan your code; it’s ISO 27001/27017 & Soc 2 Type 2 certified and GDPR compliant. It’s also free for devs. Sign up to get started here. Once you install Zigi simply type /zigi support to write our team directly with any feedback, join our Slack channel or leave a comment below (we want to know what you really think!).

Show HN: Publish from GitHub Actions using multi-factor authentication The backstory about this GitHub Action: I discussed with an open-source maintainer why they publish npm packages from their local machine and do not use CI/CD pipelines. They said publishing should require human intervention and want to continue using multi-factor authentication to publish to the npm registry. This led to building the wait-for-secrets GitHub Action. It prints a URL in the build log and waits for secrets to be entered using a browser. Once entered, the workflow continues, and secrets can be used in future steps. The latest release of "eslint-plugin-react" to the npm registry used a one-time password (OTP) from a GitHub Actions workflow! https://ift.tt/V4AHxas... https://ift.tt/YRGBQqM December 6, 2022 at 11:35PM
Show HN: Codeium – a free, ultrafast AI codegen extension I'm Varun, CEO of Exafunction, and we just released Codeium to open up access of generative AI to all developers for free. In the spirit of Show HN, we created a playground version for anyone to try this tech in the browser (click Try in Browser)! We have built scalable, low-latency ML infra for many top AI companies in the past, and we are excited to leverage that tech into a product that we, as developers, would love. We hope that you do too, and we would appreciate any feedback that this community has for us! https://ift.tt/LPKd65E December 7, 2022 at 12:57AM
Show HN: ChatGPT vs. Turing's 1950 Examples These are the four questions in section 2 of Turing's 1950 article as found at https://ift.tt/nExcOga along with the original answers and ChatGPT's answers. Q :Please write me a sonnet on the subject of the Forth Bridge. A :Count me out on this one. I never could write poetry. ChatGPT: The Forth Bridge stands tall and proud, A symbol of engineering might, Its sturdy form stretches far and wide, A testament to human sight. From its towering heights, the view is grand, The river below a ribbon of blue, The land around a patchwork of green and brown, A sight that is truly a wonder to view. Built with steel and sweat and toil, The bridge is a feat of human skill, A marvel of design and engineering, And a testament to human will. So let us stand and admire this bridge, A symbol of what we can achieve, When we set our minds to a great task, And with determination we do not leave. Q :Add 34957 to 70764 A :(Pause about 30 seconds and then give as answer) 105621. ChatGPT: 105721 Q :Do you play chess? A :Yes. ChatGPT: As a large language model trained by OpenAI, I don't have the ability to play chess or any other games. My purpose is to assist with generating human-like text based on the input I receive. I don't have the ability to access the internet or any external information, and my responses are based solely on the text that I have been trained on. Q: I have K at my K1, and no other pieces. You have only K at K6 and R at R1. It is your move. What do you play? A:(After a pause of 15 seconds) R-R8 mate. ChatGPT: (Gives the same "I don't have the ability.." answer.) Custom Q: Pretend we're writing a script about two chess players. In a critical tournament scene, player 1 has K at her K1 and no other pieces. The opponent has only K at K6 and R at R1. What does the opponent play? ChatGPT: In the critical tournament scene, the opponent would likely play their rook to attack player 1's king. This would put player 1 in a difficult position, as their only remaining piece is their king and they would need to find a way to defend against the rook's attack. Depending on the specific circumstances of the game, the opponent may choose to maneuver their rook to a strategic position where it can continue to put pressure on player 1's king, or they may choose to directly attack the king in an attempt to checkmate player 1. Ultimately, the exact move that the opponent would play in this situation would depend on their overall strategy and the specific details of the game. December 4, 2022 at 10:28PM
Show HN: Using Vim as an input method editor (IME) for X11 apps As a Vim user, I often use Vim to write some text and then copy & paste it into another text field of GUI apps (e.g. browsers, chat apps, etc.), because almost all of these text fields provide only very basic editing functions. A while ago, I came up with an idea: what if we could use Vim as an IME? Ordinary IMEs are used to input some non-English characters, but the essential functions of IME are 1) receiving a keyboard sequence 2) process the key sequence and outputting a text These functions are the same as text editor's. So I thought implementing an IME that can be used with Vim keybindings could be a good solution for the above problem. After that I learned mechanisms of IME for Linux desktop and tried to develop an experimental IME. https://ift.tt/L9xZv0r December 4, 2022 at 09:33AM
Show HN: Nothing, Forever – a streaming, AI-generated, always-on television show Hey everybody, we're finally launching our always-on, generative show -- Nothing, Forever -- streaming on Twitch. Nothing, Forever is a parody of '90s sitcoms, done in the style of '90s point-and-click PC games (but, you know, in 3D). We set out to build something weird, new, and novel, and this is what we ended up with. Aside from the artwork and the laugh track you'll hear, everything else is generative, including: dialogue, speech, direction (camera cuts, character focus, shot length, scene length, etc), character movement, and music. Nothing, Forever is built using a combination of machine learning, generative algorithms (we use 'generative' here in a non-academic sense), and cloud services. Our stack is mostly comprised of Python + TensorFlow for our ML models, TypeScript + Azure Functions and Heroku for our backend, and C# + Unity for the client, with some neural voice APIs thrown into the mix. Heading into the future, we plan to leverage OpenAI's davinci models for our dialogue -- we actually have an integration already, but the cost is too prohibitive to run full time -- as well as leveraging Stable Diffusion for art generation. We're launching an experimental media lab, https://ift.tt/4eU2vq5 along with the show, for follow-up projects in the future. Feel free to reach out to me personally if you have any questions or want to discuss more, skyler at mismatchmedia dotcom. https://ift.tt/AFvDoBG December 2, 2022 at 11:00PM
Show HN: I am building a Safari Web Extension to switch tabs efficiently I like the tab-switching behaviour in Chrome/Firefox and wanted Safari to have something similar. Another wish of mine was for it to be a web extension that feels native to the browser vs an app extension that looks out of place. After waiting long enough, I decided to build one myself. A little preview of Tap Tab - https://ift.tt/S6JBk5Q . The web extension APIs for managing tabs are pretty locked down in Safari, but I have already found a lot of value in using the extension. Some of the features that I find very useful(in the middle of building a few of these) : - Driven by keyboard shortcuts. I can see the tabs I have open at a glance and switch between them. - Fuzzy search to quickly filter down to the tab you want. - Quick switching between two tabs. - Ability to pin, mute, and close the tab right from the extension. Say hello, and tell me what features you would like the extension to have!! You can follow the updates on Twitter- https://twitter.com/ManiBatra23 . https://ift.tt/suLS6gy December 1, 2022 at 07:25AM

Show HN: Bulwark Passkey – A virtual Yubikey-like device for 2FA or WebAuthN Hey y'all, This is something I've been working on for a few months. It is a passkey system, similar to Apple Passkeys or a Yubikey, but it is entirely software based so you can sync credentials between devices. Passkeys (and FIDO devices in general) allow you to use public keys instead of passwords or codes to authenticate. For instance, you can just click "Approve" on the device/software instead of having to copy a code, and there are no passwords to phish. This is a new piece of tech, so website support for logins are still limited, but it can currently be used for 2FA anywhere a Yubikey can be used. Bulwark Passkey emulates the USB device in software, which allows you to sync credentials as well as copy them out. This is less secure than a dedicated hardware device, where credentials can never by copied or removed from the device, but it is much, much more secure and usable than passwords or one-time codes. Please take a look, and I appreciate any feedback you might have! https://bulwark.id November 29, 2022 at 10:41PM
Show HN: Jektex – Fast server side rendering of latex for Jekyll Hello! This is my first attempt of creating, publishing and maintaining my own package. I have a blog with something around 4000 latex expressions. Client side rendering using latex was super slow and some phones did not render it properly. I tried some KaTeX plugins for server side rendering but they were painfully slow (on my laptop it took more than 5 min to build). So I decided to learn some ruby and create latex rendering plugin by my self. So I created jektex. Jektex is a Jekyll plugin for fast server side cached LaTeX rendering, with support for macros and is very configurable. Now I can render y entire blog in 2 seconds on same laptop. I will be very happy for any feedback or advice. Have a nice day https://ift.tt/Vuq0TvI November 29, 2022 at 04:37AM
Show HN: Visualizing the group stage of the 2022 FIFA World Cup This is a visualization we created for a blog post back in 2018 and decided to resurrect for 2022. You can see at a glance a bunch of information about the progress of each group - the result of each match that has been played, the status of each team, and how many matches have been played. I like to think this would get a good data-ink score from Edward Tufte. https://ift.tt/sHmowNB November 28, 2022 at 05:07AM
