Show HN: Collaborative recipe manager for iOS, built with SwiftUI and Firebase https://bit.ly/3MB9zml

Show HN: Collaborative recipe manager for iOS, built with SwiftUI and Firebase 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! https://bit.ly/45t4h55 May 25, 2023 at 06:37PM

Show HN: HN Follow – Follow Your Friends on HN https://bit.ly/42fqNvy

Show HN: HN Follow – Follow Your Friends on HN 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 https://bit.ly/3omE6wh

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://bit.ly/43pkGWo ). 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://bit.ly/3MAr1r2 May 23, 2023 at 07:24AM

Show HN: Yakread – An RSS reader powered by machine learning https://bit.ly/435tL6L

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://bit.ly/3MTxcYJ... -- I'm using the implicit feedback setting. [2] Show HN for Yakread's immediate predecessor, The Sample: https://bit.ly/3h1CcKK . The Sample does bring in $1k or so per month, but long-term retention is too low for me to grow it sustainably. https://bit.ly/3MRSdmu May 24, 2023 at 06:29PM

Show HN: Mental Models for Startup Founders https://bit.ly/41ZxRMp

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://bit.ly/45wriUz... If you find it useful, please share it with others in your network. https://bit.ly/3BVbWLK May 24, 2023 at 07:27AM

Show HN: I made Hazumi, a modern HN reader for iOS https://bit.ly/3BPqP2f

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://apple.co/3BQLfIg May 22, 2023 at 03:31PM

Show HN: Blotter – An interactive, never ending music video https://bit.ly/3MsnfQG

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://bit.ly/3MtgI8n May 22, 2023 at 11:21PM
