Show HN: Reddit Firehose
4 by HotGarbage | 2 comments on Hacker News.
Inspired by the upcoming reddit API changes, I built this to (ab)use the existing free-to-use API to view the latest content being posted in a minimalist infinite doom-scrolling web app. Warning: despite filtering NSFW-tagged content by default, you'll probably see some things that aren't exactly office-friendly. User beware.

Show HN: Micro Chat – Private group chat
2 by asim | 0 comments on Hacker News.
Hey all I'm Asim. I'm an engineer who's been hacking on an open source project called Micro for the past eight years ( https://micro.dev ). In that time I've done a lot of things, all Dev related but ultimately most of my career was spent working on platforms for consumer products. After many attempts I've decided the path forward is to focus on building something that solves my own problem. Micro Chat is a solution to some of the social media problems I've been having. What I've been looking for most of my life is a community. A place to belong. I scoured the internet for that with strangers. But I think that's wrong. The public forums are also the wrong place to find that connection. What we need to do is focus on smaller communities starting with real connections. We need to strip away a lot of the addictive behaviours and issues created by social media. I think things like hackernews are great because it's very simple text based, with no notification and centers around conversations about topics of interest. I think that's how group chat should also be. The difference here is, I want a place to build small private communities e.g micro communities. Most real groups lose their value beyond a certain size. For me that's around 20 people. As an introvert I really care about strong connections with a handful of people. Unfortunately those real world connections are now spread globally as people moved away and while we have private slacks or WhatsApp grojps to stay in touch it just feels like the wrong setup for that. If anything I want to consolidate it into one place. Anyway I'm sharing this now to get some feedback. I think the tech and the product will evolve but only by finding out if others feel the same. https://micro.mu

Show HN: Magma – Multiplayer AI for Artists
16 by RushPL | 2 comments on Hacker News.
Hello HN community! I’m one of the founders of Magma, a multiplayer art platform. You might recall our earlier post ( https://ift.tt/H5pWYLr ), and today we’re sharing a significant update with our artist-focused, multiplayer AI assistant, a first in the realm of collaborative creative tools. Hope you’ll like it! See how it works in this YouTube video: https://www.youtube.com/watch?v=ZESJfjwxLjk . For in-depth understanding, here’s our documentation ( https://ift.tt/MmuisPr ) and our AI manifesto ( https://ift.tt/eWTNRa9 ) which is a guiding document for us. We're inviting you to get hands-on with this new feature. Join any of these canvases (up to 50 live contributors each): https://magm.ai/qnss , https://magm.ai/ei74 , https://magm.ai/38mr , https://magm.ai/z1ti , https://magm.ai/zdub , https://magm.ai/ed93 , https://magm.ai/1l84 , https://magm.ai/xvu5 , https://magm.ai/gd9j , https://magm.ai/pu6e . All of these canvases have extra feature flags enabled but if you’d like to go beyond them, feel free to join our beta community https://ift.tt/uG29UpP Our artist-first approach is rooted in our belief that human creativity should remain the heart of artistry. With our AI handling routine tasks, artists can focus on true creativity. Importantly, our AI preserves artists' copyright as it provides a clear distinction between human-generated and AI-generated content. Beyond just art, Magma is a powerful tool for game dev and animation, offering powerful design & review tools for all stages of the creative process. Our Slack/GDrive-like workspaces (we call them Artspaces) expose API and even shell tools. One can even render any artwork in the terminal. :) Technically speaking, our collaborative drawing engine is powered by Typescript, Node.JS, WebGL, with a hint of WebAssembly for hand-optimized performance that even Chromebooks can handle. The backend also leverages a high performance Typescript Deepkit Framework https://deepkit.io Our AI assistant runs on a worker-based architecture akin to Gitlab CI workers, currently leveraging Stable Diffusion 2.1. Future developments will allow connecting your own AI worker, training custom models within Magma, and plugging in API keys from other AI backends. Feedback, questions, thoughts? Let's discuss! Happy creating with a helping hand of AI! P.S. A shout-out to the HN community, our last post here helped us connect with an amazing technical angel investor who has made significant contributions. Looking forward to more such productive connections!

Show HN: Jitar, a runtime that automates all end-to-end communication for TS
2 by basmasking | 0 comments on Hacker News.
Do you know where you will end at the start of a new application? Me neither. Change is the only constant, and it haunts me for decades. I think that applications should be able to change without making extensive modifications and regression testing. That is my goal. In the ideal world, a simple monolithic application can grow and transition into microservices without any refactoring. Defining what runs where should be a matter of configuration, and be changed any time. And this is exactly what Jitar brings to the table.

Show HN: Candydate – TikTok Meets Tinder but for Recruitment
2 by TheRealHB | 1 comments on Hacker News.
HB here, sharing my first post ; ) I run a tech lab in the UK, and after several costly, poor hires over the years, we decided to build our own hiring tool with a focus on personality over skills. Here's the thing: resumes suck at showcasing personality! We've been using video and AI successfully and for quite some time to solve this problem. Now, we thought, why not spread the love? Especially if we can make it FREE for small businesses like ours? https://candydate.app , has the following goals: 1. Highlight true personalities using short videos, instead of relying on CVs or forms. 2. Employ AI to help rank applicants for each role, based on human factors and company culture. 3. Transform the selection process into something akin to scrolling through TikTok or using Tinder. Job seekers won't need to fill out forms, attach resumes, create an account or download anything. They just scan a QR code, record a short video, and they're done. It's truly simple! The aim was never to build an ATS (too complex for our needs) or a job listing site (there are many already). Instead, something simpler, to use wherever we already advertise vacancies, be it online or in print. We believe small businesses that lack recruitment tools (like we did) might appreciate it, although Candydate can certainly help businesses of all sizes. I have no idea how to launch or promote this type of tool, so any feedback or tips on spreading the word or improving the app would be immensely appreciated. Many thanks, HN!

Show HN: A CLI for quickly generating 3D device mockups
2 by rohanmenon | 0 comments on Hacker News.
Device mockups usually require expensive and manual tools like Photoshop to generate. I was willing to sacrifice absolute quality for a tool that could do the job much faster. Mockupgen [0] generates a 3D perspective mockup from a screenshot. Using premade templates (from the amazing work of Anthony Boyd [1]) and opencv, it masks, warps and composites the provided image onto a device rendering. I'm working on expanding the selection of devices offered (mostly MacBook and iPhone at the moment), which is a matter of finding more sources of free to use PSD mockups. Currently, it doesn't do any handling of reflections and shadows, but this is in the works.

hey hn, i’m alana, founder of basecase and creator of docbase www.getdocbase.com docbase is an open-source alternative to docsend, which lets you securely share documents and track engagement in real-time. with docbase, you can upload any document, get a secure link (with or without a password or expiration date), and view who interacts with it and when. one main use case is for founders to send their memos/decks to potential investors. as a founder and investor myself, it’s a tool i use all the time to both send and receive pitch documents. the idea came from a tweet [0], which immediately made me ping @kiwicopple with excitement. i raced to put together a very basic version 1.0 in a few days and launched it last night. luckily, it actually wasn’t too difficult using supabase for the database, authentication, and storage, next.js app router, shadcn ui [1], and vercel hosting. i’m already working on some updates for version 2.0, like improving page load performance, adding notifications, and enriching analytics. it’s entirely open-source [2], so anyone can contribute and help me make it better. i’d love your feedback, so hit me up on github or twitter with your thoughts!

Hello HN! I want to introduce fastgron, my new project. fastgron is a JSON to GRON converter, built to be incredibly fast – it's 40 times faster than Gron. GRON is a tool for making JSON greppable, but it can slow down with larger files. With fastgron, even a 200MB JSON file can be converted in just 1 second. Key features include streaming conversion for memory efficiency and an optimized path reconstruction for faster operations. It leverages C++ and the simdjson and fast_io libraries for speed. I welcome all feedback, suggestions, or questions. Thank you!

Show HN: Open Fire Serverless CI
3 by jjdelannoy | 0 comments on Hacker News.
Hello, HN community, I'm really excited to show you Open Fire a serverless CI, how does it work? relying on serverless technologies (firecracker) we can spin up a new VM in less than 200 ms running in a more powerful and newest CPU on the market, just change 1 line of code on your GitHub Actions Workflow and you're up and running! You can see our use case, where we implemented Open Fire in the NextJS repo taking down build time from 1 hour 17 minutes to 26 minutes which is a 66 % of improvement without any engineering effort! [1] The value of a CI/CD Pipeline is inversely proportional to how long the pipeline takes to run and is a limiting factor for companies to release quickly and often. For a little bit of background, I have been working in the CI/CD space for the last 9 years in small startups, my own CI/CD startup for mobile games, and big enterprises like PayPal and Binance, and you see the same pattern emerges In today's life developers are pretty good when they're building new features on their local machines, they have top-edge hardware like MacBooks with tons of core and RAM, but when they push and need to run all CI/CD steps building (multi-arch x86, x86_64, ARM), unit testing, e2e they start to feel very frustrated with the state of the art of their CI/CD pipeline because those will be running on some cloud provider crappy VM that has between 2vCPU 4 GiB to 4 vCPU 8 GiB of RAM, is in that place when they see that their local workflow from 2 minutes build time will become something in the range of 30 minutes to 1 hour! And if you want to migrate to self-hosted CI you will get: High cost of idle infrastructure waiting to pick up jobs to run. Big queues for accessing the resource to run your pipelines, because everyone is working at the same time frame the high demand overlaps and you can't scale your self-hosted solution that fast without building a team of ~ 20 people. Spent all day installing and updating all the dependencies of the VM and now have to maintain the software packages installed on that machine Companies tend to have 3 different kinds of CI/CD platforms inside them, legacy systems using Jenkins and for new systems GitHub or GitLab, and Buildkite, so you need to create and maintain new runners for all these CI/CD systems, pre-install software for all the build pipelines that may run in your runner Now you have a new platform to develop, update and support every day for the whole company.

Hello, HN community, I'm really excited to show you Open Fire a serverless CI, how does it work? relying on serverless technologies (firecracker) we can spin up a new VM in less than 200 ms running in a more powerful and newest CPU on the market, just change 1 line of code on your GitHub Actions Workflow and you're up and running! You can see our use case, where we implemented Open Fire in the NextJS repo taking down build time from 1 hour 17 minutes to 26 minutes which is a 66 % of improvement without any engineering effort! [1] The value of a CI/CD Pipeline is inversely proportional to how long the pipeline takes to run and is a limiting factor for companies to release quickly and often. For a little bit of background, I have been working in the CI/CD space for the last 9 years in small startups, my own CI/CD startup for mobile games, and big enterprises like PayPal and Binance, and you see the same pattern emerges In today's life developers are pretty good when they're building new features on their local machines, they have top-edge hardware like MacBooks with tons of core and RAM, but when they push and need to run all CI/CD steps building (multi-arch x86, x86_64, ARM), unit testing, e2e they start to feel very frustrated with the state of the art of their CI/CD pipeline because those will be running on some cloud provider crappy VM that has between 2vCPU 4 GiB to 4 vCPU 8 GiB of RAM, is in that place when they see that their local workflow from 2 minutes build time will become something in the range of 30 minutes to 1 hour! And if you want to migrate to self-hosted CI you will get: High cost of idle infrastructure waiting to pick up jobs to run. Big queues for accessing the resource to run your pipelines, because everyone is working at the same time frame the high demand overlaps and you can't scale your self-hosted solution that fast without building a team of ~ 20 people. Spent all day installing and updating all the dependencies of the VM and now have to maintain the software packages installed on that machine Companies tend to have 3 different kinds of CI/CD platforms inside them, legacy systems using Jenkins and for new systems GitHub or GitLab, and Buildkite, so you need to create and maintain new runners for all these CI/CD systems, pre-install software for all the build pipelines that may run in your runner Now you have a new platform to develop, update and support every day for the whole company. And the list goes on [1] - https://ift.tt/0W65uCK... Thanks for reading, if you want to try us, want to say high, or give us some feedback just ping me jean _at_ open-fire.dev - Jean

Hi HN ! I was getting a bit sick of how I was managing structures in Python, I needed something that would trivially be translated to json, had some kind of verification, and had the ability to output a json-schema to communicate the format. I plan to add more documentation and customization to the package in regards of schema generation and custom validation. For python 3.9 + I hope this will be useful ! :)

Show HN: A High-Performance CRC Hardware Generator in Bluespec SystemVerilog
2 by SandmanDZ | 0 comments on Hacker News.
What is it and why make it? The Cyclic Redundancy Code(CRC) is an error-detecting code commonly used in digital networks and storage devices to detect accidental changes to digital data. And blue-crc repo provides a parallel, pipelined and highly-parameterized hardware implementation of CRC targeting high-throughput applications, such as network transmission. CRC is a mature and widely-adopted error-detecting technology, and there have been numerous hardware implementations of it. However, most existing hardware designs are either implemented using pure combinational logic or are only designed to process input data byte-by-byte serially, which results in extremely low throughput. Other designs targeting high-performance applications lack proper parameterization and only support some specific CRC configurations. Blue-crc aims to solve these problems by providing both high-throughput and well-parameterized CRC hardware implementation. Main Features of Blue-CRC Complete CRC Configuration: the implementation supports complete CRC configuration parameters, including polynomial, initVal(the initial CRC value), finalXor(the result is xor’d with this value if desired), reflectData(if True, the input bit order is reversed), and reflectRemainder(if True, the result bit order is reversed). Standard Interfaces: The input interface follows AxiStream protocol, with a parameterized data width. The output CRC result is guarded by the basic handshake protocol. Parallel: The IP is designed to process multiple bytes per cycle. Fully Pipelined: The implementation takes in raw data and produces results every cycle. High Throughput: The implementation, configured with 256-bit input and 32-bit CRC output, runs at 500MHz on Xilinx xcvu9p FPGA. Have a try? For BSV users, you can import our codes and instantiate CrcAxiStream interface in your design directly. Besides, we provide a script to generate custom Verilog CRC implementation automatically. If you are interested in high-performance CRC hardware acceleration, it’s worth giving it a try. We are also open to any recommendations for further improving our designs.

Show HN: Pika – Custom ChatGPT-like chatbots for any website
2 by theionman | 0 comments on Hacker News.
Hello everyone, My name is Alex and I am the founder a VC-backed startup. Recently, I’ve used the Open AI API to create an internal chatbot that the team could use. Basically, I wanted to allow the team to ask questions about any company-related information and get answers immediately. That chatbot was trained mainly on our Notion docs, as well as memos and notes taken by the team. Later on, that chatbot was also used by my company’s website, to help our acquisition efforts. The results were great and given that we didn’t have the capability to get back to every customer inquiry from our previous chat widget, the chatbot I created was a huge success. I ended up creating an entirely new product called Pika so that it can be used on any website. This is how it works. People login the platform, they add sources of information to the chatbot’s knowledge base (either documents, URLs or free-form text), and click on a button to create a chatbot. Then the chatbot is trained on the sources of information provided; this usually takes less than 30 seconds. The chatbot now knows everything about the sources of information provided. It can answer any question and every answer can be analyzed and later edited so the chatbot can learn from its mistakes. You can see a demo of Pika at https://trypika.com Please try it out and let me know if you have any feedback. I am also happy to take any other technical questions you may have. Thanks.

2 by udit99 | 0 comments on Hacker News.
Hey guys I've been playing the guitar for many years but I felt like I had hit a wall and wasnt making progress. One of the things I realized was holding me back was unfamiliarity with the fretboard. I'd often find myself in situations like “Uhh…Where’s the C# here?” “Where’s the flat-3rd of this root on the 4th string?” “Sure would be nice to know the closest min7 triad shape to play over here..” I tried memorizing the fretboard the obvious way but it extreeemly boring for me. Being a developer, I decided to turn it into a game. I'd love for you guys to try it out and let me know what you think: It's at [www.fretboardfly.com]( https://ift.tt/KshbQfW ) I've only built the first module right now which is for note memorization but there's been enough interest that I'm planning on building more modules. Please let me know if you like it, what you'd change about it and what other modules you'd like to see in future. The stack is Vue 3/Nuxt 3/Firebase/Firestore/Tailwind deployed on Vercel.

Show HN: Collaborative recipe manager for iOS, built with SwiftUI and Firebase
2 by thebricklayr | 0 comments on Hacker News.
I initially created Umami for my family. We'd been using a giant google sheet of recipes that my wife made (one recipe per tab plus a table of contents at the front), but the UX of that left much to be desired, especially on mobile. We also tried a bunch of other recipe apps like Paprika, Whisk, Mela, etc., but most of them don't let you create a shared collection of recipes without using the same login credentials, which we didn't want to share with extended family members. Anyways, I've steadily been working on Umami as a solo side project for about 3 years. At first, just my family and a few friends were using it, but now it's starting to get downloaded by other people. I'd love to get feedback here on what kinds of features would be helpful to y'all. Also happy to answer any questions about the tech stack. Thanks friends!

Show HN: HN Follow – Follow Your Friends on HN
38 by stevekrouse | 22 comments on Hacker News.
HN Follow lets you follow authors on Hacker News, and get email notifications when they post. It was inspired by alerthn.com and hnreplies.com. The app was built in an experimental style on Val Town. We’re trying to create a new web primitive that you can: 1. write like a function 2. run like a script 3. fork like a repo 4. install like an app This is our 5th iteration of this same “HN Follow” app. We launched the 3rd version here on Hacker News six months ago[1], but it was very kindly removed from the front page by dang in favor of us launching Val Town itself first, which we did in January[2]. We’re trying to strike the right balance between something you can use and install with one click, and something you can infinitely customize. For example, you could fork `@rodrigoTello.hnFollowApp`[3] and change the input parameter from authors to a generic query, like I do here[4] to get notifications whenever “val town” is mentioned on HN. In addition to emailing myself (via `console.email`), I also send a message to our team’s Discord. The possibilities are endless, but it can also be overwhelming. We’re trying to find the balance where we help you navigate the space of possible integrations, without limiting you the way a no-code tool would. We would really appreciate your guys’ feedback and suggestions!

Show HN: Gis.chat – a Geospatial Community
44 by do-me | 8 comments on Hacker News.
Hi folks! I'm excited to show you gis.chat, a geospatial chat platform in both senses: a platform about geospatial topics and a geospatial platform itself, referencing the location of our communities. The setup is fairly simple and reproducible: a plain Zulip instance and a homepage with geospatial search capabilities. It seems almost trivial but it has some very nice features. I guess you should be familiar with Zulips stream/topic model to follow along ( https://ift.tt/415e8XV ). The core idea is that there are city-specific streams (currently represented by a pin), but there could just as well be streams about points of interest, line geometries (e.g. a river) or polygons (e.g. national park). - Every local stream can have the same topics, e.g. "general", "news", "meetups", "jobs" etc. - With Zulip's search you can either search for a particular topic, e.g. "news" in a local stream or instead in all streams and have some kind of news feed of the community with "topic:news" - Once more communities are added, specific filters could be added, e.g. country-wise or by drawing your own area of interest - Eventually, for the ones who like, users could associate themselves with a local community in their profile or add there main location so one could not only search for the local communities but instead also for individuals There are many nice features in Zulip's pipeline that would foster gis.chat: - Further nesting of streams/topics - Semantic search If for example Zulip would allow for saving coordinates (or better an entire geometry) in the Postgres DB, with the help of PostGIS, Zulip's search could allow for bounding boxes (or custom geometries). Let me know if you have any kind of other ideas or feedback!

Show HN: Yakread – An RSS reader powered by machine learning
3 by jacobobryant | 0 comments on Hacker News.
This is a web-based reading app I've been working on since August. The main differentiator is that Yakread uses machine learning to rank the articles in your feed: as you click on articles from a particular RSS/newsletter subscription, other articles from that subscription will tend to be ranked higher in the future (via a bandit algorithm). Yakread also uses ML to recommend articles that other users have read, so your feed will have articles in it even before you sign up and add your own subscriptions. For the recommendations, I'm using the collaborative filtering implementation from Spark MLlib[1]. I model RSS feeds instead of individual articles: when you click an article, that counts as a "point" for that article's RSS feed; at recommendation time, the algorithm first selects an RSS feed to recommend, and then it picks one of the popular/recent articles from that feed. To counter popularity bias, I have a pre-ranking step that probabilistically filters out RSS feeds that have already been recommended a lot. I manually approve all RSS feeds before they're eligible to be recommended. In addition to scrolling through the algorithmic feed, you can read articles chronologically on the subscriptions page, which I sometimes prefer when I have a larger chunk of reading time. There's also a daily digest email that lists new articles from your subscriptions; skimming that is part of my morning routine. I find the whole system gives me a nice balance between algorithmic filtering and manual control. This is the culmination of the past four years I've spent as a full-time bootstrapped founder; Yakread both scratches a personal itch and attempts to fix various deficiencies that my previous businesses have had. In a nutshell, I've come to believe that "discovery is a feature, not a product," which is why Yakread is a full reading app instead of a standalone recommender system like my previous products.[2] From a business perspective, the recommendation algorithm is primarily intended to help onboard new users quickly/easily. More ideologically, I think RSS is ready for a comeback :). [1] https://ift.tt/HEZwrSz... -- I'm using the implicit feedback setting.

This is a web-based reading app I've been working on since August. The main differentiator is that Yakread uses machine learning to rank the articles in your feed: as you click on articles from a particular RSS/newsletter subscription, other articles from that subscription will tend to be ranked higher in the future (via a bandit algorithm). Yakread also uses ML to recommend articles that other users have read, so your feed will have articles in it even before you sign up and add your own subscriptions. For the recommendations, I'm using the collaborative filtering implementation from Spark MLlib[1].

Show HN: Mental Models for Startup Founders
2 by paraschopra | 0 comments on Hacker News.
Hello HN, I launched Wingify/VWO (Visual Website Optimizer) here on HN in 2010. The initial momentum and feedback I got from this place was a key reason I was able to profitably bootstrap the company to roughly ~$30MN ARR. Over the last 2 years, I have been writing a book for startup founders that's informed by my experience with Wingify and many failed attempts before it. It's finally done, so thought of launching it on the same forum where it all started for me :) There are a total of 68 mental models covering various aspects of building a startup: - Choosing markets - Building products - Ecosystems and partners - Thinking about Moats - Approaching marketing - B2B v/s B2C - Hiring & culture Unlike other books, I'm not sharing my story and neither take a very prescriptive approach. Rather, I use mental models to shine light and provide a tractable way of looking at problems an entrepreneur encounters during her startup. I understand that entrepreneurship cannot be systemized, but I'm hoping some of the mental models I share help in clearer thinking and faster decisions. Would love your feedback on the book: https://ift.tt/haJTZES... If you find it useful, please share it with others in your network.

Show HN: Making passive investing safer and better for everyone
3 by SirLJ | 2 comments on Hacker News.
Dear Friends, my name is LJ and I am the Master of the Universe at Alternative Systems and Really Wild Technologies. We are changing the world by making Passive Investing Safer and Better for all everyone! It all began with my poor investment choices like diversified portfolio of mutual funds, pretty much investing equally in the 5 mutual funds available through my employer and the life and science fund did great for a bit before the dot com crash :-) Not long after, I changed jobs and had to sell the funds, because in kind transfer was not possible with the new employer and lost most of the money. It was scarring experience, so I stayed in money market funds and missed the market upside. Few years latter, another job, another pension plan and this time I was determined not to make the same mistakes. Everyone is saying Passive Investing is the best for the average investor, but they never tell you what index fund to buy and more importantly when exactly. Just holding an index fund for the long term can be actually a mistake and if you’re in the wrong index at the wrong time, it can take you 5, 10, or even 15 years just to break even… In last 20 years or so, we had 2 major black swan events resulting in two 50% drawdowns and this is very important to avoid, because the market might remain under water for very long period of time. It gets even worse at the bottom of a recession, people lose jobs and needs the funds to survive and if down already 50% and take half of the rest to live off until the next job, there is no coming back: if you are down 75%, you will need 300% gain to break even, 80% loss will need 400% gain, etc… You can check the Research tab on the website [1], but basically the model delivers the same returns compared with Buy and Hold, but cutting the drawdown by half: worst draw down 23.83% vs 56.48% for the buy and hold model, which means you need less than 33% gain to break even vs more than 122% gain needed to break even with the Buy and Hold Model Not long ago while speaking with friends and co-workers about the way I invest, it actually donned on me that this can be an actual company, as I have the backend already up and running for years, I just put together this simple website and I am applying to YC and hopping to create a company that can truly change the way people are investing for the long run. How it works is the systems sends an email advising every Friday after the market close advising to be either in Cash or invested in any low cost S&P tracking 500 ETF / mutual fund / employer provided fund. I know long term and passive investing is boring and in this model the average portfolio change happens once a year, so from the Startup School, I got the idea on how to get people more engaged – with the “Make Money with Us” feature, basically you get 50% referral commission every month on every user you bring along. This way you can spread the word to all your friends and show them how it invest better and also offset the subscription costs: you get 2 users to sign and the subscription is free and if 10 users, you can generate $1200 per year real passive income to help you start investing if you do not have the spare cash to do so… Please take a look and let me know what do you think, what do you like, don’t like, and please share any feedback, ideas, recommendations, etc , it will be greatly appreciated, so we can make the product batter and more useful for everyone. I have applied to YC and plan to reapply if not selected, but what other accelerators should I apply to? PearX, Afore Capital, etc, what else? I am also looking for a growth/marketing/sales co-founder, so any idea where I can find one? Please note, this is the short version, because of the characters limit, the original is here [2] Special Thanks to dang for his time, great advice and all help with this!

Show HN: A better IP Lookup tool I made
4 by michaelbuckbee | 2 comments on Hacker News.
Most other IP lookup tools I've found are mostly just trying to push you to signup for their API, which is fine but less useful if you're just trying to figure out which IP addresses in your log files are from sketchy locations and likely to do bad things to your application. I merged together a bunch of APIs and some of our own honeypot collected data to make something I hope devs and security folks find useful. If you want to try out a "bad" IP, try this one: https://ift.tt/t1S08ux

Show HN: YouTube Summary CLI
2 by mmaorc | 0 comments on Hacker News.
This simple tool was born out of a personal need for a more efficient way to consume YouTube content. It provides you with a short and segment-wise summary of a YouTube video. Each segment is printed with a link to that part of the video. I know there are several Chrome extensions that do this, butI work with different browsers so I wanted a simple CLI app for that. Hope this helps anyone else. Any feedback would be much appreciated

Show HN: Open-source data integration platform tailored for AI startups
10 by jasonwcfan | 0 comments on Hacker News.
My cofounder and I used to work at Robinhood where we shipped the company’s first OAuth integrations, so we know a lot about how data moves between companies. For example, we know that the pain of building new API integrations scales with the fragmentation in the industry. In the current meta, we see this pain with a lot of AI startups who invariably need to connect to their customers data, but have to support 50+ integrations before they even scale to 50+ customers. This is the process for an AI startup to add a new integration for a customer: - Pore over the API docs for each source application and write a connector for each - Play email tag to find the right stakeholders and get them to share sensitive API keys, or give them an OAuth app. It can take 6+ weeks for some platforms to review new OAuth apps - Normalize data that arrives in a different formats from each source (HTML, XML, text dumps, 3 different flavors of markdown, JSON, etc) - Figure out what data should be vectorized, what should be stored as SQL, and what should be discarded - Detect when data has been updated and synchronize it - Monitor when pipelines break so data doesn’t go stale This is a LOT of work for something that doesn’t move the needle on product quality, so it’s no wonder that most startups are still relying on file uploads to onboard their early customers. The problem is file uploads are slow and insecure and don't scale. That’s why we built Psychic.dev to be the fastest and most secure way for startups to connect to their customer’s data. You integrate once with our universal APIs and get N integrations with CRMs, knowledge bases, ticketing systems and more with no incremental engineering effort. We abstract away the quirks of each data source into Document and Conversation data models, and try to find a good balance to allow deep integrations while preserving general purpose utility. Since it’s open source, we encourage founders to fork and extend our data models to fit their needs as they evolve, even if it means migrating off our paid version. To see an example in action, check out our demo repo here: https://ift.tt/2kqYQIg We are also open source and open to contributions, learn more at docs.psychic.dev or by emailing us at founders@psychic.dev!

Hi HN, WikTok is a UI for Wikipedia that lets you quickly swipe (or use your arrow keys) to navigate between random and recommended articles (based on the previous articles you interacted most with). It's just a fun project I hacked together this weekend, so may be a little rough around the edges, but I'd love to get your thoughts. Let me know if you have any suggestions (or find any interesting articles!) Cheers,

Greetings Hacker News family! I'm excited to share with you the first version of our AI-powered travel planner. I'm a digital nomad/tech geek who loves traveling but admittedly am lazy about trip planning, so I created a tool built on ChatGPT that could help me jump start that. I simply enter a destination, the # of days, a budget preference, and it spits out a full travel itinerary with highlighted points of interest. The problem: Trip planning can be overwhelming and time consuming. While some may find excitement in planning, many folks are overwhelmed by the prospect of figuring out where to go and what to do once you arrive at your destination. The typically requires copious amounts of research in order to uncover the major attractions, determine their relative proximities, and weave everything together into an actionable travel itinerary. To complicate things, everyone has different preferences for the types of activities they would like to partake in. The solution: Planit Earth aims to help travelers shortcut this process by leveraging the power of AI to generate personalized itineraries with just a click. The vision over time is for Planit Earth to become the go-to resource for your trip planning needs. Look forward to hearing your thoughts!

Show HN: Loadable – Simplifying Async Data Handling in React
2 by tobi-piece | 0 comments on Hacker News.
I'm excited to share a project that I've been working on - Loadable, a new NPM package to help reduce boilerplate and simplify handling asynchronous data in React applications. Features include: - *Loading State Management*: Manages the loading state for you, removing the need for manual management. - *Error Handling*: Handles errors during data fetching, providing a unified way to deal with potential issues. - *Data Fetching Based on Dependencies*: Fetch data based on dependencies, similar to `useEffect`. - *Support for Synchronous and Asynchronous Functions*: Can work with both sync and async functions. - *Type-Safe*: The library is fully typed, offering strong TypeScript support. Check it out here: [https://www.npmjs.com/package/@tobq/loadable](https://www.npmjs.com/package/@tobq/loadable) Feel free to follow on twitter: [@tobi_akin](https://twitter.com/tobi_akin) Feedback and suggestions are very welcome, as I'm hoping to make this as useful and practical for you all as possible.

Show HN: Trogon – An automatic TUI for command line apps
12 by willm | 0 comments on Hacker News.
Hi HN, Trogon is a project to generate a TUI for command line apps. It presents the arguments, options, and switches as a form. Editing the form generates a command line, which you can then run with a keypress. I'm a lover of the command line. But I can recall only a fraction of the switches for most commands I use. I would love it if there was a TUI available for most commands. Trogon currently works with Python and the Click library, but I would like it to cover more of the Python ecosystem and also generate TUIs for apps not written in Python. More information in the repository. Let me know what you think...

Show HN: SpaceBadgers – Free and Libre SVG Badges
2 by splittydev | 0 comments on Hacker News.
Greetings, Hacker News community! I am thrilled to present SpaceBadgers, a new free and open-source SVG badge generator I've been working on. It's located at badgers.space. SpaceBadgers is born out of the desire to offer more flexibility and customization for project badges, often used in open-source projects. It's fully open source, provided under the permissive MIT license, and will always be provided for free. The core badge worker is written in Rust, and so is the library behind it, which you can also find on crates.io under the name spacebadgers. I am excited to receive your feedback and suggestions. Check it out and let me know what you think in the comments. Contributions are also welcomed and appreciated. You can find the source code here: https://ift.tt/6R1q7Qw .

Show HN: Mapname – anonymous social network for organising points of interest
17 by bnd | 5 comments on Hacker News.
Hello HN, with mapname you can create a unique name for any particular point of interest as in prefix(id).group(optional).suffix. Once a mapname created then this can be used as an address, discovered and socialised. Mapname is free and has no advertisements. At onboarding pick a unique prefix. That is all about onboarding. Users can also organise collection of places with just two words, for example coffee shops i like at NY is abc.1 or I have visited Melbourne last year where you can see at abc.melbourne Mapname designed as an anonymous Social Network where users particular perspective engage with like minded users, instead of their persona. Personal Images are not promoted. Here is one minute user guide https://www.youtube.com/watch?v=G42THV9YcY4 More mapnames are on twitter https://twitter.com/NameYourWay You can consider this as "Pinterest of coordinates" Another way to think this; mapname(s) to coordinate(s) is similar to domain name(s) to ip address(es). Instead of hard to remember IP Addresses we use domain names. Similarly instead of coordinates or map list urls a mapname can be in use. Between mapname and a coordinate 1->1 or N->1 or 1->N relationships are possible. Whenever a mapname visited, the most relevant what3words attached to it so that you may communicate whichever is more relevant. Mapname is trying to reduce friction while describing addresses and organising points of interests, for transportation, navigation, directions uses integrations. A mapname can be viewed in your favourite maps (Google Maps, Apple Maps, Yandex Maps, Bing Maps, Baidu Maps) or with what3words, citymapper, waze. it is available on android & ios, feel free play with it, any feedback or question is appreciated. What other location/navigation/map integration would you benefit?

Show HN: Swap.js – a JavaScript micro-framework (HTML fragments over the wire)
12 by josephernest | 3 comments on Hacker News.
Hi HN! I created this lib in the need of a simple and tiny framework to easily do AJAX-style navigation / replacement of fragments in the page, in a web application. For people who don't want to use client-side-rendering and complex frameworks à la React, there are nowadays a few "HTML-over-the-wire" libraries, like HTMX, Unpoly or this super-tiny one Swap.js :) One other key thing is that no external tool is needed: no bundler, no webpack, no TypeScript compiler, no minification needed. Just write HTML, JS (+ your preferred server-side language: PHP, Python, etc.) and it works. The framework makes use of fetch (of course) but also MutationObserver API to be able to launch actions when parts of the DOM change. Let me know what you think!

Show HN: Jesth – Next-level human-readable data serialization format
6 by alexrustic | 4 comments on Hacker News.
Hi HN ! I'm Alex, a tech enthusiast. I'm excited to show you Jesth, a next-level human-readable data serialization format. This project started out as a markup language for writing the docstrings of functions that would ultimately be consumed by a documentation generator. Basically the idea was to split a docstring into sections like Description and Parameters. Each section would consist of a header in square brackets and a body (lines of text between two headers). Here's what a docstring for a sum function would look like: This function takes in two integers a and b and returns their sum. [parameters] - a: First integer - b: Second integer [return] Sum of a and b The Description section in the example above is actually an anonymous section, i.e., a section with an empty header. Meanwhile, I was thinking of a way to automate part of my dev workflow by storing in a file commands grouped into tasks such as project creation, build, testing, release, et cetera. Similarly with the markup language for my documentation generator, I would use square brackets to define the tasks. Thus, a task would consist of a header and a body which would be a list of commands to be executed sequentially. I built this project and named it Backstage. Here is a hypothetical backstage.tasks file: [release] & test & generate_doc & git_stuff & build # upload to PyPI $ twine upload --skip-existing dist/* [git_stuff] $ git add . $ git commit -m {message} $ git push origin master The example above is illustrative only and would not work. It contains 2 sections "release" and "git_stuff". Running the "release" task from the command line is equivalent to sequentially executing the commands in the "release" section. The documentation generator and the scripting language, despite the obvious similarity in their formats, did not share any parsing code. So, to stop repeating myself, I created a file format and its library named Jesth which stands for "Just Extract Sections Then Hack". The library acts as an incomplete INI file parser that only hands the programmer the sections (as headers and their associated bodies which are lists of strings). No further interpretation of the data is done by the parser, allowing the programmer to unleash their creativity through useful hacks. In its latest iteration, Jesth has matured and also includes a proper and extensively tested hack to convert a compatible section into a dictionary data structure, making Jesth my de facto preferred format for config files. I find Jesth more readable than TOML, YAML, and JSON. Here, encoding a dictionary data structure in its own section with another section containing a prompt for ChatGPT: [prompt] I want you to act as a detective story writer. I will provide you with two dictionary data structures representing the profiles of two people. Your goal is to write a thrilling neo-noir story. My first request is: "guess who the killer and victim is from the profiles, then build a story that includes every detail of the profiles". [profile] # This section can be converted into a dictionary data structure name = 'Jane Doe' birthday = 2000-12-23Z10:17:37Z photo_jpg = (bin) VGhpcyBpcyBub3QgYSBwaG90by4uLiBCdXQgdGhhbmsgeW91 IGZvciB5b3VyIGludGVsbGVjdHVhbCBjdXJpb3NpdHkgOyk= --- books = (dict) romance = (list) 'Happy Place' 'Romantic Comedy' sci-fi = (list) 'Dune' 'Neuromancer' epitaph = (text) According to the law of conservation of energy, no a bit of you is gone; you are just less orderly. --- [profile] name = 'John Doe' birthday = null books = (list) 'American Predator' 'Mindhunter: Inside the FBI's Elite Serial Crime Unit' You can learn more by reading the project's README and playing with the demo.

Show HN: Beepberry – a portable e-paper computer for hackers
23 by erohead | 7 comments on Hacker News.
Hi. I heard HN likes e-paper gadgets so I wanted to share a little side project I’ve been working on with @sqfmi. We’re building Beepberry - a portable e-paper computer for hackers, designed for chatting on Beeper. My day job is running Beeper [0], but I will always have a soft spot for building hardware. I wanted to create a ‘weekend’ device that would let me stay in touch with friends and family, without the distractions of a full smartphone. I imagined a tiny, hackable e-paper screen with a physical keyboard, powered by a Raspberry Pi, that I could use to chat around my home…and pretty much nothing else. Before Beeper, the idea probably would not have gone anywhere. Most chat apps do not have an API, making it practically impossible to hack something like this together. Enter Beeper, with connections to 15+ chat networks. Built on top of Matrix, Beeper is fully hackable. You can write alternative fun clients [1], bots [2] and more! Today, sqfmi is starting to take pre-orders at https://ift.tt/rQYqB4u for the first batch. It’s $79 (or $99 including a Pi Zero). Specs: Sharp Memory LCD (same display tech as in Pebble!), Pi Zero (BT/WIFI), physical keyboard, 2000mAh lipo. On top of being an amazing Beeper chat device, it’s basically an e-paper Cyberdeck that fits in your pocket. It’s a ton of fun to hack on. Keep in mind - THIS IS NOT A REAL FINISHED PRODUCT. It’s basically a devkit. More info in the blog post: https://ift.tt/Ywb5lMU , or join the Discord/Matrix channel https://ift.tt/POWTh0i... . I’ll hang out a bit here to answer questions as well.

Show HN: Till.sh, enhanced access controls for AWS S3
4 by alukach | 0 comments on Hacker News.
Hi everyone, I'm an independent developer who has been building an S3-related project over the past few months: https://till.sh . I wanted to share it in its MVP state to get others' opinions on the idea and to see if anyone is interested in being an early tester. ## What is it The core concept is that Till provides an S3 API proxy that authenticates with its own custom keys. This enables us to build features that are not easily achievable with standard AWS credentials. Namely, we can add data limits to the keys, time-based expiration of keys, quickly surface access logs, and apply custom billing policies to auto-invoice users based on their data access. ## Why I built it Till was born out of having built numerous custom data portals for clients in my professional work. These were typically organizations that have large interesting data sets (e.g. ML training sets, satellite imagery, etc) and want to share access to their data but needed some guard rails to prevent run-away costs, needed fine-detailed access tracking to analyze data access, or are looking to recoup costs associated with the creation and storage of the data. It felt like these needs were common enough to be turned into a project to allow people to start sharing their data within a few minutes. Being that Till provides an S3-compliant API, it immediately fits into many of the existing workflows and clients that end-users are already using. ## What I'm looking for So that's the pitch. I'd love to get thoughts and critiques. Does this seem like a product you or someone you know would use? It's a bit niche so I'm admittedly struggling to get an estimate on the size of the market it could serve. Any obvious needs or use cases that I'm missing? At this stage, I'm trying to get as many people using the project as possible, so let me know your GitHub handle if you signup and I'll happily up your key-limit on the free tier. Many thanks. Looking forward to hearing your thoughts.

Show HN: No-code AI-powered API endpoints
8 by sudb | 5 comments on Hacker News.
Backengine is a tool that evolved from an experiment at my startup for which we wanted to pass structured data to an LLM completion API and receive structured data back. We thought we'd release it as a standalone tool for others who might also find it useful. Backengine lets you create hosted API endpoints for which the endpoint logic is described in natural language as an LLM prompt. The endpoints accept structured requests and return structured responses. Why is this useful? Hosted - no additional infrastructure to maintain. Prompt engineering workspace - you can edit, test and tweak endpoint prompts without touching any code. Instant deployment - created endpoints should be immediately available, and changes to your endpoints are deployed in one click. This is a first and very early release - we'd love for HN to try out Backengine and hear what you think! There's a playground where you can try it out - we're very interested to hear what use-cases people come up with.

We built this app (Is here!) specifically for Teams as a handy way to notify employees of new deliveries. Using AI label recognition it can search your company directory and send a notification in chat. The platform is free to trial for 30 days. It just needs your tenant admin to permit proactive messaging. We would love your feedback!

Show HN: A Solution to durably store your likes/dislikes counts
2 by jsdeveloper | 0 comments on Hacker News.
Hi All, vDB is Solution to durably store your likes/dislikes count (or any count of your choice). Its takes O(1) time to read and put unsigned long values to DB, as it similar to Arrays (there are no keys but you use index to store counts). Single header only C++ file for storing and retreiving numbers. And one more thing it does this without increasing the file size, as its not append only DB. Which also means it can be slower on simultenous writes. Well if you task is just to store likes/dislikes counts, than it must not be much of a problem. As reads are done more than writes for such cases.

Show HN: Willow – Open-Source Privacy-Focused Voice Assistant Hardware
16 by kkielhofner | 0 comments on Hacker News.
As the Home Assistant project says, it's the year of voice! I love Home Assistant and I've always thought the ESP BOX[0] hardware is cool. I finally got around to starting a project to use the ESP BOX hardware with Home Assistant and other platforms. Why? - It's actually "Alexa/Echo competitive". Wake word detection, voice activity detection, echo cancellation, automatic gain control, and high quality audio for $50 means with Willow and the support of Home Assistant there are no compromises on looks, quality, accuracy, speed, and cost. - It's cheap. With a touch LCD display, dual microphones, speaker, enclosure, buttons, etc it can be bought today for $50 all-in. - It's ready to go. Take it out of the box, flash with Willow, put it somewhere. - It's not creepy. Voice is either sent to a self-hosted inference server or commands are recognized locally on the ESP BOX. - It doesn't hassle or try to sell you. If I hear "Did you know?" one more time from Alexa I think I'm going to lose it. - It's open source. - It's capable. This is the first "release" of Willow and I don't think we've even begun scratching the surface of what the hardware and software components are capable of. - It can integrate with anything. Simple on the wire format - speech output text is sent via HTTP POST to whatever URI you configure. Send it anywhere, and do anything! - It still does cool maker stuff. With 16 GPIOs exposed on the back of the enclosure there are all kinds of interesting possibilities. This is the first (and VERY early) release but we're really interested to hear what HN thinks!

Show HN: Tack, a fast lightweight scripting language for games and embedding
3 by PlumeCat | 0 comments on Hacker News.
https://ift.tt/63yzFtJ Hi HN! Tack is a scripting language I've been working on sporadically for the past year or so, and intensely for the past few weeks. It originated out of a desire for something that was like Lua, but with a more familiar syntax, and without some of the other surprises in Lua such as the 1-indexed tables. It's also been a great learning project, and a very satisfying challenge! While the current version is early beta at best, I hope to continue working on it and maybe see some adoption. Despite the relative lack of optimization, I'm very pleased with the performance so far - although I haven't done a huge amount of benchmarking, it seems to be significantly faster than the stock Lua 5.4 interpreter for the quicksort test, and the btrees test (copied from the Computer Language Benchmarks Game). The language is designed for embedding in C++ programs, and is written in C++ more or less from scratch including the handwritten recursive descent parser, and a register-based compiler/interpreter. The only dependency other than the standard library is my C++ adaptation of the khash library used for the object type - a from-scratch hashmap seemed not worth the trouble. Quick code example - more examples in the repo! fn quicksort(arr) { const n = #arr if n <= 1 { return arr } " find the midpoint " let l = min(arr) let r = max(arr) if r == l { return arr } const mid = (l + r) / 2 " split array into upper and lower " const upper = filter(arr, fn(x) { return x < mid }) const lower = filter(arr, fn(x) { return x >= mid }) " recursively sort the upper and lower sub-arrays and join the result" return quicksort(lower) + quicksort(upper) } let A = [] for i in 0, 1000000 { A << random() } let before = clock() let B = quicksort(A) let after = clock() print("Time taken: ", after - before, "seconds") Building requires just cmake and a C++20 compiler - tested with MSVC 2022, g++11 on WSL and Clang 15 on M1 https://craftinginterpreters.com was a great help with implementing closures, as I had gone down a blind alley with my first approach for locating the closed-over variables. However I have taken a slightly different approach towards boxing. As I do intend to use this for some small games myself going forward, there is a standard library already, and plans to expand it. I also intend to release a GLFW-based mini game framework along with precompiled binaries, so hobbyists (and younger relatives!) may use it without needing a full compiler toolchain. I would love if anyone is interested enough to try it out! James

Show HN: WhyBot, making GPT-4 question itself
5 by johnqian | 2 comments on Hacker News.
Hi HN — we’re John and Vish! We built WhyBot, a tool to help you deeply explore a question or topic. You ask a question, and WhyBot responds by building an ever-expanding knowledge graph. It does this by recursively generating answers and follow-up questions. You can change its persona to change the flavor of the generations (try toddler mode!). We originally built this for the AngelList Agent Hackathon ( https://twitter.com/AqeelMeetsWorld/status/16502799744050421... ) and got a lot of interest from folks asking to play around with it. So we thought it’d be fun to brush it up and release it as a web app! It’s a work in progress and we plan on adding more features, such as saving, sharing, focusing on one branch and potentially executing code. We hope you enjoy playing around with it and would love to hear any of your feedback or thoughts.

I've been working in the couple of months on an experiment, trying to make GPT-4 much more useful for web development / React, writing production code that is relevant to any repository without copy pasta from ChatGPT or having small snippets of auto-complete from Copilot that are not in your context. The agent is taking a user story text and generating and composing multiple react components to generate the relevant screens, based on atomic design principles, with Typescript, TailwindCSS and RadixUI. Is is still experimental but very interesting results, I would like to get your feedback on it! It is completely open-sourced, looking for contributors!

Show HN: Infinity Whiteboard, Designed for Teachers
3 by jakegmaths | 0 comments on Hacker News.
I've created a whiteboard which I use every lesson when teaching maths, though it can be used for anything. It currently has a few hundred teachers using it daily. It's designed for use with touch-screen interactive whiteboards in classrooms, and stays in sync with your phone/tablet/whatever without signup/login. You can also find me on Twitter where I post updates etc: https://twitter.com/jakegmaths Some features and cool things: * Sync devices without signup - offline by default, just hit 'sync devices' and use the same code on multiple devices to sync * Touch-first - 1 finger draws; 2 finger pan/zoom; 3 finger gestures like changing pen colour * Add images - when teaching, this is usually photos of student work taken on my phone and auto-sync'd to the whiteboard at the front of the room * Add PDFs - when teaching, these are usually past paper exams which I then annotate over with the class * Zen mode - 3 finger tap or hit the ∞ icon to hide the UI; something I use every lesson so students can focus on the actual maths (there's also a fullscreen button when not on iOS) * Visualiser - often when teaching we'll work on paper with a webcam aka 'visualiser' pointing down at it; this projects that to the main whiteboard, with optional cropping, freeze-frame and snapshots * Screencast - many teachers use eg PowerPoint to teach; instead, I'll use PowerPoint in edit/design mode rather than slideshow mode, with a locally-cast cropped portion of that on the main whiteboard at the front of the room. This enables me to eg edit my PowerPoint as I go and use all the PowerPoint tools not available in slideshow mode * Instant replay - hit the play button to play back all the scribblings currently showing on the screen * Magnet mode - when sync'd with another device, use the magnet icon so the other device follows you. Most of my teaching is now via a tablet-with-stylus anywhere in the room, and as I pan/zoom around with the tablet the main whiteboard comes with me... but only when I want it to by activating the magnet * Student mini-whiteboards (MWBs) - if my students have devices and I want them to use them, I 'sync devices' then enable student MWBs and each student has a live copy of the whiteboard, and I can see what they write and can showcase any student instantly on the main board * PWA support - install as a PWA and you can download whiteboards as .iwb files which can then be double-clicked to open/edit on desktop * Free - I have no plans to charge for this Other things you may find interesting from a tech perspective: * The client is a single <5,000 lines HTML file, with JS, CSS, SVG-favicon all inlined (plus PDF.js lazily loaded if you add a PDF) * This is vanilla Javascript with no frameworks or libraries (except PDF.js) and no minification or build scripts - just view-source and check out how ugly all my code is! * 77.6kB for everything (except PDF support)... the size of 'modern' websites frankly disgusts me * The server is just a single ~500 line Javascript file and runs on Deno (also ported to Bun but unstable for now) and really just serves some static files, deals with websockets and temporarily stores images people add * Costs ~£5/month on Heroku * There's no database or any long-term persistence - Heroku servers restart every 24h and nothing is saved beyond that; it's all ephemeral
