Show HN: Build a SQLite satabase from your Reddit data https://news.ycombinator.com/item?id=36062256
Show HN: Build a SQLite satabase from your Reddit data With Reddit's upcoming API changes[0], I got nervous that I'd no longer be able to access the many posts and comments I've left there over the years. Inspired by the Dogsheep projects[1], this CLI lets you immediately pull your most recent 1k comments & 1k posts (the max allowed by the paged API) into a nicely-structured SQLite database. It's perfect for loading into Datasette for nice viewing & full-text search of your content. Taking it a step further, the project's killer feature is the ability to import data from GDPR archives. This allows you to store your full Reddit history (including deleted comments and posts on removed subreddits). I hope you find this tool useful! I'll be around to answer questions and field comments (or feel free to open a GH issue). [0]: https://old.reddit.com/r/reddit/comments/12qwagm/an_update_r...

Show HN: Gis.chat – a Geospatial Community https://news.ycombinator.com/item?id=36040612
Show HN: Gis.chat – a Geospatial Community 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://zulip.com/help/streams-and-topics ). 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! https://gis.chat May 22, 2023 at 11:24PM
Show HN: Yakread – An RSS reader powered by machine learning https://news.ycombinator.com/item?id=36061427
Show HN: Yakread – An RSS reader powered by machine learning 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://spark.apache.org/docs/latest/mllib-collaborative-fil... -- I'm using the implicit feedback setting. [2] Show HN for Yakread's immediate predecessor, The Sample: https://news.ycombinator.com/item?id=27664020 . The Sample does bring in $1k or so per month, but long-term retention is too low for me to grow it sustainably. https://yakread.com/ May 24, 2023 at 10:29AM

Show HN: Mental Models for Startup Founders https://news.ycombinator.com/item?id=36054769
Show HN: Mental Models for Startup Founders 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://invertedpassion.com/free-book-mental-models-for-star... If you find it useful, please share it with others in your network. https://invertedpassion.com/free-book-mental-models-for-startup-founders/ May 23, 2023 at 11:27PM

Show HN: Willow Inference Server: Optimized ASR/TTS/LLM for Willow/WebRTC/REST Hey HN! Willow Inference Server (WIS) is a focused and highly optimized language inference server implementation. Our goal is to "automagically" enable performant, cost-effective self-hosting of released state of the art/best of breed models to enable speech and language tasks: Primarily targeting CUDA (works on CPU too) with support for low-end (cheap) devices such as the Tesla P4, GTX 1060, and up. Don't worry - it screams on an RTX 4090 too! (See benchmarks on Github). Memory optimized - all three default Whisper (base, medium, large-v2) models loaded simultaneously with TTS support inside of 6GB VRAM. LLM support defaults to int4 quantization (conversion scripts included). ASR/STT + TTS + Vicuna 13B require roughly 18GB VRAM. Less for 7B, of course! ASR. Heavy emphasis - Whisper optimized for very high quality as-close-to-real-time-as-possible speech recognition via a variety of means (Willow, WebRTC, POST a file, integration with devices and client applications, etc). Results in hundreds of milliseconds or less for most intended speech tasks. See YouTube WebRTC demo[0]. TTS. Primarily provided for assistant tasks (like Willow!) and visually impaired users. LLM. Optionally pass input through a provided/configured LLM for question answering, chatbot, and assistant tasks. Currently supports LLaMA deriviates with strong preference for Vicuna (I like 13B). Built in support for quantization to int4 to conserve GPU memory. Support for a variety of transports. REST, WebRTC, Web Sockets (primarily for LLM). Performance and memory optimized. Leverages CTranslate2 for Whisper support and AutoGPTQ for LLMs. Willow support. WIS powers the Tovera hosted best-effort example server Willow users enjoy. Support for WebRTC - stream audio in real-time from browsers or WebRTC applications to optimize quality and response time. Heavily optimized for long-running sessions using WebRTC audio track management. Leave your session open for days at a time and have self-hosted ASR transcription within hundreds of milliseconds while conserving network bandwidth and CPU! Support for custom TTS voices. With relatively small audio recordings WIS can create and manage custom TTS voices. See API documentation for more information. Much like the release of Willow[1] last week this is an early release but we had a great response from HN and are looking forward to hearing what everyone thinks!

Show HN: A recipe parser to get rid of the cruft. I need you to break it https://news.ycombinator.com/item?id=36043947
Show HN: A recipe parser to get rid of the cruft. I need you to break it I made a recipe parser to get rid of all the cruft on recipes. Check it out: https://recipeplz.fly.dev/ Has this been done? Yes. Does this project use AI? Also yes...but barely. What it does do is grab various forms of metadata that recipe sites often provide for SEO reasons (as per schema.org Recipe spec). It's commonly ld+json, but can be other formats as well. The trick is this: What the numerous recipe sites output is not always the same - there are many variations of the schema.org specs used for Recipes, so this project attempts to correct for that. It's just a bunch of conditionals. If all else fails, it uses AI as a fallback to parse a recipe and return valid ld+json Recipe data based on Schema.org's Recipe spec. I even say "please" to the AI overlords. If a request for a recipe seems to take a long time, you'll know it's pinging OpenAI's API (the Chat API via the 3.5-turbo model). I'd love to see if you can find a recipe that breaks it! May 23, 2023 at 06:29AM

Show HN: I made Hazumi, a modern HN reader for iOS https://news.ycombinator.com/item?id=36031944
Show HN: I made Hazumi, a modern HN reader for iOS Hello HN, I'm thrilled to announce the launch of my first app, Hazumi, a Hacker News reader, available for free on iOS! I’ve been lurking on HN for around 2 years while working on this project seeing people post amazing HN reader apps of their own. I’ve always figured Hazumi wasn’t good enough yet to post here but if I wait around until I’m ready, I’ll probably never share so here goes… Hazumi is a modern Hacker News app for your pocket with some intentional limitations. Stories are displayed on a simple colourful card, with images, that condenses all the information you need at a glance. Out of the box you get accessibility features for system settings like light/dark mode and text size. Others are controlled in app for opening stories in a Web View vs externally via Safari, defaulting to Reader Mode and reducing animation bounciness. You can browse top, new and best sections, limited to 30 stories each, which refresh every hour on the server. I’m not a fan of infinite scrolling or spending a lot of time reading news. I just want to get in and get out while keeping up on the latest. Other notable features: - Basic search - Widgets for your Home and Lock Screen - Apple Watch app - Warns you of non-HTTPS links There are a few “PRO” features that require a subscription ($/€1.99 monthly): - AI summaries of comments on stories that have at least 30 root level comments - In app newsletter (yesterday’s top 10 stories) - Bookmarking with iCloud support - Themes (change the colour of the cards) - Supporting indie developers and keeping the lights on for Hazumi Working on: - Better comments/tappable links - Enhancing search - More themes Being the first version, it's very early days for Hazumi and there are bugs that I’m working on fixing. I'm eager to improve it and shape its future based on your input. I welcome any feedback you may have, whether it's about existing features or ideas for new ones. Your thoughts will be instrumental in shaping Hazumi, making it an even more useful tool for tech news enthusiasts. Please give it a try and let me know your thoughts. P.S. Shout out to MB and MC for your awesome feedback during the TestFlight beta! https://apps.apple.com/ie/app/hazumi/id1670237209 May 22, 2023 at 07:31AM

Show HN: Blotter – An interactive, never ending music video One day I was listening to a playlist and wished there could be some cool visuals to go along with it. Blotter is a proof of concept I hacked together that does a bit of audio recognition combined with a few generative AI models (both text and img) to create visuals that are relevant to the song. The video stream is generated in real time at 24fps - you can try it yourself by requesting visuals in the Twitch chat using the "!v" command! Right now it's mostly a fun hack project, but I am tinkering with new model architectures for higher fidelity video as well as an interactive tool so people can make videos with their own audio files. I'd love to hear any feedback or suggestions, thanks! https://www.twitch.tv/blotterstream May 22, 2023 at 03:21PM
Show HN: Psychic - An open-source integration platform for unstructured data https://news.ycombinator.com/item?id=36032081
Show HN: Psychic - An open-source integration platform for unstructured data 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 level of fragmentation and number of competing "standards". 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. 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 for deep integrations while maintaining broad 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://github.com/psychic-api/psychic-langchain-tutorial/ We are also open source and open to contributions, learn more at docs.psychic.dev or by emailing us at founders@psychic.dev! https://github.com/psychic-api/psychic May 22, 2023 at 07:41AM

By Enrique Aguilar
A full season of Sunday Streets starts this weekend! Check out the upcoming schedule below.
Sunday Streets 2023 is here, featuring three community parties, two signature mile-plus routes and the Third Annual Phoenix Day block party program.
The 15th season will kick off on Galvez Avenue and Mendell Street in Bayview on May 21 from 12 p.m. to 5 p.m. Residents and visitors alike will celebrate the neighborhood's vibrant diversity with cultural programming, health resources, local vendors and recreational activities for all ages. It is completely free and open to everyone!
Each neighborhood's character makes the experience a distinct adventure. As the streets come alive with music, dance, and community spirit, SFMTA project experts will be on hand with updates and information on various transportation options.
In partnership with Livable City and Into The Streets, the SFMTA proudly supports this series of events that empower communities to transform their streets into car-free community spaces. The Sunday Streets program creates temporary open spaces and recreational opportunities in neighborhoods that typically lack such resources. It encourages physical activity, fosters community-building and inspires people to reimagine their streets as vibrant public spaces that everybody can enjoy.
Sunday Streets encourages alternative modes of transportation such as public transit, biking, walking or rolling. Leave your car behind and join the movement toward greener and healthier ways of getting around.
Sunday Streets 2023 Season Schedule
Western Addition – September 24
Check out SFMTA.com for trip planning information to or near Sunday Streets events and Muni service impacts. For real time updates, visit our Twitter (https://twitter.com/SFMTA_Muni). For more about the program, visit SundayStreetsSF.com.

Join people across the city bicycling today for the annual Bike to Wherever Day. The SFMTA is proud to be the official citywide sponsor of Bike to Wherever Day 2023, San Francisco's favorite biking celebration!
Hosted by the San Francisco Bicycle Coalition, Bike to Wherever Day celebrates bicycles as a fun and healthy way to get around. This annual event invites people to pedal to their destinations, and it promotes bicycling both as an alternative commute and as a healthy and safe alternative to driving to…wherever.
We encourage everyone, including those who don't usually bike, to get out and cycle today. After grabbing some wheels (your own or a bikeshare bike), consider joining one of the Neighborhood Rides. Need more reason to stop by? You also can pick up your free Bike to Wherever Day canvas tote bag, filled with goodies, courtesy of the SF Bicycle Coalition.
Resources to Help You Plan Your Bicycle Trip
The SFMTA has go-to resources to help you plan your bicycle trips. The interactive bike network map highlights recommended routes and shows bikeshare station locations. Go to our Get Out, Get Going website to find an interactive multi-mode map with information about other sustainable ways to get around that you could pair with your bicycle trip, including walking and using shared mobility devices, like a scooter or moped.
The SFMTA supports low-carbon transportation options like bicycles, and we continue to expand our dedicated bike lanes around the city to make streets safer and more comfortable for bicycling.
You can check out our Slow Streets Program with over 18 corridors that have traffic limitations so they can be used as shared spaces with walkers and bicyclists. Biking, scooting and rolling are integral to our new Active Communities Plan, a 2-year process to develop a plan for active mobility in San Francisco. For more information, visit the project website (SFMTA.com/ActiveCommunities).

Show HN: Jesth – Next-level human-readable data serialization format https://news.ycombinator.com/item?id=35991018
Show HN: Jesth – Next-level human-readable data serialization format 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: Till.sh, enhanced access controls for AWS S3 https://news.ycombinator.com/item?id=35975876
Show HN: Till.sh, enhanced access controls for AWS S3 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. https://till.sh May 17, 2023 at 07:41AM

Show HN: No-code AI-powered API endpoints https://news.ycombinator.com/item?id=35974924
Show HN: No-code AI-powered API endpoints 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. https://backengine.dev/ May 17, 2023 at 06:25AM

Show HN: CounterDB, to persist your likes/dislikes counts A Solution to durably store your counts. For example number of likes/dislikes on a post. Its time complexity is O(1). Single header only C++ file for storing and retrieving numbers. It does this without increasing the file size, as its not append only DB. Which also means it can be slower on simultaneous writes to an index. Well if your 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. https://github.com/anuragvohraec/CounterDB May 16, 2023 at 10:50PM

Show HN: Willow – Open-Source Privacy-Focused Voice Assistant Hardware 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 https://news.ycombinator.com/item?id=35939720
Show HN: Tack, a fast lightweight scripting language for games and embedding https://github.com/PlumeCat/tack 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 https://github.com/PlumeCat/tack May 14, 2023 at 10:39AM

Show HN: WhyBot, making GPT-4 question itself 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. https://whybot-khaki.vercel.app/ May 13, 2023 at 09:17PM

Show HN: Learn beautifully, with content-specific AI lessons Hi HN, For 4 years I've worked on the psychology of learning following a CompSci degree with an AI minor from back in 2019. I love the future of effective learning that is coming. This is a way for you to study for specific exams, lectures and videos. You upload your content, and get specific, citing flashcard exercises delivered in a fun way. Not only can you view the timestamp in the video that a question was generated from, for example, but your answers are used to inform a "Compilation stage". The Compilation stage uses your choices of answers (and wrong answers), as well as data on when you clicked to "Explain why", to summarise your knowledge gaps and create a specific action plan for studying the next day - a plan which conceptually understands Involved in this tool are transformer models, including the classics (BERT, T5, etc), the new kid (ChatGPT), and embeddings (for balls-amazing lessons segmentation).

Show HN: Emacs major mode for editing QuakeC files As a part of my personal Quake Renaissance I decided to fulfil my childhood dream of making a mod for the game I played 25 years ago. Surprisingly, I discovered there was no Emacs mode available for QuakeC! So I came up with one. It currently mostly supports Vanilla QuakeC and assumes FTEQCC as a compiler but given some interest I am more than happy to add as many features as necessary for a modern Emacs experience. https://github.com/vkazanov/quakec-mode May 13, 2023 at 02:12AM

Show HN: Infinity Whiteboard, Designed for Teachers https://news.ycombinator.com/item?id=35915929
Show HN: Infinity Whiteboard, Designed for Teachers 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 https://www.mathsuniverse.com/infinity May 12, 2023 at 06:26AM

Show HN: Play SineRider, a math puzzle game built by teenagers at Hack Club Messing with your TI-84 graphing calculator is a rite of passage for every teenager who has ever been bored in a math class. In 2013 I was that teenager, and it gave me an idea for a tiny game about sledding on graphs. This project grew into my white whale, and I spent my twenties trying and failing to finish it alone. I shelved the game when I started working for Hack Club in 2018—until last May, when a few community members took it off the shelf. The project took on a life of its own, and turned into a year of nights and weekends from a global team of 20+ teens in 8+ countries. Today SineRider enters public beta! SineRider is literally an infinite universe of function composition puzzles, each with infinite solutions, that range from welcoming for 9th graders to difficult for even the most serious matlab user. And every day we tweet out a fresh one to be solved with your morning coffee. We hope you enjoy playing SineRider as much as we’ve enjoyed making it. And we’re not done! Mobile support, polar coordinates, and a level editor are all on the roadmap. SineRider is a living project, to be continuously built and maintained as free OSS by the Hack Club community: https://github.com/hackclub/sinerider The team that built the game will try to be in the comments today between high school classes and AP tests. —chris walker, creative director Watch the trailer: https://www.youtube.com/watch?v=35nDYoIwiA8 Play now: https://sinerider.com https://github.com/hackclub/sinerider May 8, 2023 at 06:14AM

Show HN: Make domain verification as easy as verifying an email or phone number https://news.ycombinator.com/item?id=35827952
Show HN: Make domain verification as easy as verifying an email or phone number Hi HN, This is a project [1] I've been working on for a little while and I'm interested in your feedback and point of view. Many of us would have verified a domain name by pasting a string into a DNS TXT record. Some providers ask us to store this DNS TXT record at a domain using a DNS label like "_provider" e.g. _provider.yourdomain.com, and some providers ask that you do it at the zone apex (God help us [2]). The Domain Verification protocol stores a DNS TXT record at a DNS name derived from a hashed "verifiable identifier" (think email, telephone, DID), enabling anyone that can prove control over the verifiable identifier to prove authority for the domain name. For example, the domain verification record giving the email address user@example.com authority over the domain dvexample.com can be seen with this terminal command: dig 4i7ozur385y5nsqoo0mg0mxv6t9333s2rarxrtvlpag1gsk8pg._dv.dvexample.com TXT The record can specify what type of services the authorised party is allowed to use (e.g. SEO, Storage, Advertising) or specify an exact provider (ads.google.com), you can also specify an expiry date. The benefits of this approach are: - Domain owners can grant time-limited, granular permissions for third parties to verify a domain - Every service provider could use the same verification record - Once a domain owner creates a verification record by following instructions from one service provider, that same record could be used by other service providers - Domain registrars could set these records up on behalf of users, perhaps even upon domain registration (with registrant opt-in). This would provide domain registrants with a fast lane for signing up to services like Google Ads, Facebook Ads, Dropbox, whatever I'm still working on licensing but creating these records will always be free. I hope to find service providers that see significant upside in reducing friction for user onboarding that are willing to pay to license it. Worked example: Let's say you want to authenticate the user with the email user@example.com with the domain dvexample.com, these are the steps: 1. HASH(user@example.com) -> 4i7ozur385y5nsqoo0mg0mxv6t9333s2rarxrtvlpag1gsk8pg 2. Store Domain Verification record at: 4i7ozur385y5nsqoo0mg0mxv6t9333s2rarxrtvlpag1gsk8pg._dv.dvexample.com 3. TXT record determines permissions and time limit: @dv=1;d=Example user emali;e=2025-01-01;s=[seo;email];h=4i7ozur385y5nsqoo0mg0mxv6t9333s2rarxrtvlpag1gsk8pg BTW, if you're interested the syntax of that DNS record is a compact data serialisation format I created especially for DNS [3]. Thanks for taking a look, Elliott 1. https://www.domainverification.org 2. dig target.com TXT 3. https://www.compactdata.org (edit: formatting) https://www.domainverification.org May 5, 2023 at 04:40AM

Show HN: The pure Python SaaS starter kit https://news.ycombinator.com/item?id=35764635
Show HN: The pure Python SaaS starter kit Hi HN, Recently, I’ve noticed there’s a decently high barrier to entry in developing competitive, full-stack SaaS applications. Beside the standard, boring features that take months to implement, you typically have to know several languages and frameworks, and be familiar with fancy frontend styling classes. I’m working hard right now to solve this problem by building PySaaS- The 100% pure Python SaaS starter kit. PySaaS is a boilerplate Python codebase that takes care of the fundamental components standard to all SaaS applications. The codebase uses the Pynecone web framework to compile your frontend into a NextJS app, so you never have to touch any HTML, CSS, or Javascript. Pynecone is easy to learn, yet fully flexible and powerful enough for advanced use cases. We implement out-of-the-box functionality for secure Firebase user authentication, Lemon Squeezy subscription management (MoR removes a major tax headache), Notion as a headless blog CMS, and more. Our mission is to help developers and founders save months of development time and focus on building unique features, which will in turn provide more opportunities to generate revenue and give value to customers. And easily do it in pure Python! Frontend. Backend. All in Python. To check out the live demo for free, click the link and then the “See Demo” button. Let me know what you think. https://pysaas.io April 30, 2023 at 10:22AM

Show HN: Eva AI-Relational Database System for Faster AI-Powered Applications Hi friends, We are building EVA, an AI-Relational database system with first-class support for deep learning models. Our goal with EVA is to create a platform that supports AI-powered multi-modal database applications operating on structured (tables, feature vectors, etc.) and unstructured data (videos, podcasts, pdf, etc.) with deep learning models. EVA comes with a wide range of models for analyzing unstructured data, including models for object detection, OCR, text summarization, audio speech recognition, and more. The key feature of EVA is its AI-centric query optimizer. This optimizer is designed to speed up AI-powered applications using a collection of optimizations inspired by relational database systems. Two of the most important optimizations are: + Caching: EVA automatically reuses previous query results (e.g., inference results), eliminating redundant computation and saving you money on inference. + Predicate Reordering: EVA optimizes the order in which query predicates are evaluated (e.g., running faster, more selective deep learning models first), leading to faster queries. Besides saving money spent on inference, EVA also makes it easier to write SQL queries to set up multi-modal AI pipelines. With EVA, you can quickly integrate your AI models into the database system and seamlessly query structured and unstructured data. We are constantly working on improving EVA and would love to hear your feedback! https://github.com/georgia-tech-db/eva April 30, 2023 at 09:52AM

Muni Metro Fix-It Week Maintains the Subway Infrastructure
Muni Metro Fix-It Week Maintains the Subway Infrastructure
By Jessie Liang
Published April 28, 2023 at 11:17AM
https://www.sfmta.com/blog/muni-metro-fix-it-week-maintains-subway-infrastructure
By Jessie Liang
Track crew removing old rail at the Van Ness crossover
The first Muni Metro Fix-It Week of 2023 was a resounding success in March, and it’s also the first Fix-It Week since the SFMTA launched the Central Subway in early January of this year. Here is a behind-the-scenes video recap. Fix-It Week is the SFMTA’s quarterly effort to optimize work time by closing Muni Metro early for critical maintenance. The SFMTA’s Maintenance of Way (MOW) teams did an excellent job maintaining the subway and preventing future breakdowns.
Fix-It Week helps the Muni Metro get a 20% improvement in speed and about a 20% improvement in reliability in the subway. It takes fewer minutes to take the N Judah from the Outer Sunset to Embarcadero now than it did in 2019.
From March 16 to March 22, 2023, the Muni Metro Subway between Embarcadero and West Portal closed at 9:30 p.m. to provide SFMTA maintenance crews an extended window to perform underground infrastructure improvement work that cannot be completed during the usual overnight windows. During the subway closure, buses provided substitute service for Muni Metro lines on the surface and connected all stops on Market Street.
Track crew powerwashing station walls
The goal of Fix-It Week is to make Muni metro subway operations more reliable, ensure safety, and improve the customer experience. Nine MOW teams, Track, Cable Car, Motive Power, Maintenance Engineering, Mechanical Systems, Overhead Lines, Underground, Paint Shop and Signal, were involved in the maintenance work.
Major maintenance work includes:
- Track replacement and reinstallation from the Ferry Portal to the Van Ness Crossover
- Mechanical systems cleaning, maintenance and installation
- Signal repairs and upgrades, including the demolition of old train control system racks, equipment and wiring
- Track fastener and subway lighting surveys, and drain cleaning around switches
- Overhead Line inspections and Overhead Section Break hardware adjustments
- Debris removal and traction power substation inspections
- Cable Car maintenance and repairs
Custodial staff cleaning Church Station
The SFMTA teams completed over 2,000 hours of maintenance and inspections over the seven night shutdown. They were able to perform 161 feeder operations, replace more than 125 bulbs for trackway lighting in multiple locations, renew 750 feet of Overhead Contact System contact wire, replace eight blue light phones and inspect approximately 8,000 track fastener plates from the Ferry Portal to Powell Station.

A support team was also contributed to the success of Fix-It Week. These staffers helped coordinate maintenance work, upheld all safety standards and ensured that subway service resumed on time every day.

Show HN: Jarvis AI – Text, iMessage, and Email ChatGPT https://news.ycombinator.com/item?id=35740538
Show HN: Jarvis AI – Text, iMessage, and Email ChatGPT We're back with another ShowHN! When we launched, you could text Jarvis AI using regular SMS messages from your phone. Since launching 3 weeks ago[1], we've introduced two new channels for using ChatGPT. Now you can use ChatGPT over SMS text message, iMessage for Apple-enabled devices, and via Email. It is super interesting to forward an email to Jarvis AI and see its thoughts on your email thread. It can help you brainstorm or it can suggest a reply to previous emails. 10 messages free forever, more volume is free over iMessage and Email for a limited time (until the HN hug of death!). You don't have to sign up or anything to try it. Just send a text to: +1 (855) 676-1two89. Thanks for checking this out. Many exciting features are coming soon to make this more than just a different interface to ChatGPT. We want to make AI accessible to more people, over more channels, with more useful things for your day-to-day. For medical professionals, we added the /diagnose command. Ask Jarvis "/diagnose 32 year old harsh cough" for example. Soon, we are adding features like /invoice for generating invoices and /remember for notes and reminders.

Show HN: ScrapScript – A tiny functional language for sharable software Hi friends, I started casually working on scrapscript in 2015. I built a few compilers over the years to test out various ideas/implementations, and I think I'm finally happy with the overall design. The code is not public yet. Email me at hello@taylor.town if you're interested in joining the core team later this year. Let me know if you have any questions or feedback :) https://scrapscript.org April 26, 2023 at 04:45AM

Show HN: Karrio – Open-Source Multi-Carrier Shipping API https://news.ycombinator.com/item?id=35727026
Show HN: Karrio – Open-Source Multi-Carrier Shipping API Hey HN! Daniel and Delali here; we are working on Karrio, an open-source shipping infrastructure. Our focus is on making it easy to integrate shipping into platforms. With Karrio’s open-source and universal shipping API, you can set up connections to a worldwide network of shipping carriers for national, international and last-mile services but also build your own network of local carriers. You can seamlessly add built-in shipping functionalities to your platform, enabling users to fetch live rates, buy labels, track packages, and more. You can check out our Github repo here: https://github.com/karrioapi/karrio . For developers in the logistics space, carrier integration is often a painful experience. We believe that an open-source solution is a viable alternative to building a shipping system from scratch in-house or getting locked in with a Saas multi-carrier API. Karrio aims to put you in control of your shipping network with lower engineering costs. (see how to get started here: https://docs.karrio.io/quick-start ). So far, we’ve built a unified shipping API compatible with most major carriers, such as FedEx, UPS, DHL, USPS, Canada Post, and more. With the flexibility of open-source, Karrio has interoperability with other multi-carriers and 3PL (EasyPost, Freightcom, etc.). And we plan on building more integrations. Karrio is evolving with the help of our community of early adopters, and we want to keep that going. Checkout our README to get involved with the project, file issues and request or contribute carrier integrations We currently offer a managed cloud service in private beta, with a pay-as-you-go plan for platforms and custom prices for enterprise customers. Don’t hesitate to reach out if you have any questions. We would love to hear your feedback and how Karrio can help with your project. https://github.com/karrioapi/karrio April 27, 2023 at 05:29AM

Show HN: Scrawl-canvas filter functionality demo The Scrawl-canvas library's filters functionality is inspired by SVG filters. Filter operations can be ordered in ways to combine different sets of operations to achieve complex effects. The library comes with an extensive set of pre-built filters, including: color and alpha channel manipulations; matrix, pixellate, blur; compositing and blending operations; palette reduction and dithering; image and noise asset upload (for use with composites and blends); gradient, and displacement, mapping. Filters can be applied to individual graphical objects, to Groups of such objects, and also to Cell displays.

Show HN: An interactive map showing live wind farm generation in Great Britain https://news.ycombinator.com/item?id=35712238
Show HN: An interactive map showing live wind farm generation in Great Britain GB Renewables Map an energy experiment created entirely in my free time (day job is visualisation at Octopus Energy). It's an interactive map showing live generation for major wind farms in Great Britain, showing what each wind farm is generating both now and in the past, and where that generation is physically located. Animated weather data is from WeatherLayers and shows current and historic wind conditions on the map, providing context to wind generation around the country. History mode allows you to go back in time and see wind generation and weather conditions for a particular date and time. It's great for exploring days of record generation, such as the 21.6GW record on January 10th, 2023! Prediction mode lets you see what wind farms are estimated to be generating using current wind conditions and model based on historic generation and wind speeds. Is a wind farm generating as you expect, or is there something to look into? An experimental feature allows you to see what future wind farms could be generating today (or in the past!) if they were already built and operational. If you click the "sparkle" button on the map you'll get to see what the upcoming 3.6GW Dogger Bank wind farm is estimated to generate if it was operational today. There's an "About" section on the site that goes into detail on the various public data sources and how some of the features work. I also document a lot of this on my Twitter @robhawkes if you're curious. This is just the start and there are many more features to come! Please let me know your comments and suggestions. https://renewables-map.robinhawkes.com April 26, 2023 at 04:53AM

SFMTA Retires the Orion, First Hybrid Bus in Cleanest Transit Fleet
SFMTA Retires the Orion, First Hybrid Bus in Cleanest Transit Fleet

San Francisco’s first low-emissions electric hybrid Orion bus
Muni’s Orion hybrid buses are headed for retirement as we phase in a brand-new batch of El Dorado hybrid electric buses. It’s the end of an era for San Francisco’s first low-emissions electric hybrid fleet that travels the city’s toughest routes.
Orion hybrid fleet tackles Muni’s toughest routes starting in 2007
The Orion buses have been a testament to the SFMTA’s commitment to the latest green transportation technologies. Muni, which previously had relied on a diesel bus fleet in coordination with our electric trolley bus fleet, transitioned to its first 30-foot Orion diesel hybrid-electric buses in 2007. This was the start of the SFMTA’s addition of these lower emission vehicles to one of the greenest fleets in the country, ensuring better air quality city wide.
The Orions brought the agency closer to achieving its goal of an all-electric fleet and a carbon-neutral San Francisco by 2040. This is consistent with San Francisco’s Climate Action Plan to dramatically reduce harmful emissions in communities.
The Orions’ pint size made them ideal for winding routes like the 36 Teresita, which weaves through Twin Peaks, Diamond Heights, Glen Park and Bernal Heights. Many riders have taken Orions on their adventures along San Francisco’s curving streets, steep hills and tight turns. One can only imagine their sentimental value, especially among those who frequent the 36, as well as the 35 Eureka, 37 Corbett, 39 Coit and 56 Rutland routes.
The Orions were among the first low-floor hybrid buses to serve San Francisco, and the first with closed-circuit security cameras to help keep Muni riders safe. Their interior was fitted with internal destination signs to help customers know when their stop was approaching. The 30-foot coaches were designed to accommodate easier boarding and provide quieter, more efficient operation.
Their arrival offered us an opportunity to train Muni mechanics on hybrid vehicle maintenance. The agency continued to maintain the fleet even after the Orions’ assembly manufacturer went under in 2012.
The new El Dorados are primed to fill the gap left by their predecessors. Like the Orions, they are low-floor buses with a short wheelbase, making them ideal for navigating San Francisco.
As their taillights fade into the horizon, the Orion hybrid bus fleet takes a much-deserved place in the history of San Francisco transit. They conquered the winding hills of Glen Park and navigated the twisting turns of Telegraph Hill. They will be remembered as the first of Muni’s fleet to pioneer hybrid batteries, moving Muni closer to a zero emissions future.
