Show HN: Scan QR codes to check-in guests registered via Google Forms™ Hi HN! I made a no-code platform for creating physical data collection apps, using QR codes [1]. It does not yet have a self-service config UI though, which limits adoption. That's why I recently released a Google Forms™ add-on for QR code check-in, based on the platform. This focused use-case makes it easy to provide a fully self-service config UI. How it works: 1. Create your Google Form as you normally would [2] 2. Activate the add-on if you hadn't already [3] 3. Craft a confirmation email to be sent to each form responder Upon each form submission, the add-on will send a PDF with a unique QR code (a V4 UUID) to the responder. Have guests present this code at the event, and record check-ins in bulk using the included QR scanner. See here [4] for more information, or try the Google Sheets™ version [5] (which doesn't send email). [1] https://ift.tt/i5mpKuf [2] https://ift.tt/9UVhsWg [3] https://ift.tt/LeJcv2p...

Show HN: Meal planning app I built after losing 50kg myself in 2022 1500cals is a calorie and excercise tracking tool that I built after losing 50kg myself in 2022 through simply watching what I ate and starting to exercise. The main "trick" I uncovered is simply to plan meals ahead. It sounds boring, it sounds annoying, but really its such a tiny effort for such outsized and life changing rewards that it should be a no-brainer. The existing tools I found were more focused on tracking after eating which is great in terms of capturing data and measuring over time, but I found really didn’t help me with locking in a routine. I wanted to fix this and bring some of this planning side along with tracking into an easy to use app. This is 1500cals! https://1500cals.com December 27, 2023 at 10:14PM

Show HN: Capit – Social Media Image Caption Generator Hey HN! I just recently released my latest iOS App, Capit - it is a simple app built to generate captions for social media posts, all directly from images & video, utilizing gpt-4-vision. Users just choose an image, select a tone, and get 5 great caption options. My latest update adds Profiles to allow you to save your settings for different social media profiles, along with a simple caption editor to let you customize your captions further. The app is a subscription service - but lets you try it for free if you just hit the X button on the paywall. I built the app as my wife runs a small business for which Instagram is a huge traffic generator...but she often gets stumped at what to write in terms of captions, especially when we've been open for years and it feels like you are just recycling content in many cases. Capit isn't really meant to automatically post for you - it is a tool for improving your own creativity. I'd appreciate any & all feedback! https://capit.app December 24, 2023 at 12:49AM

How Your Feedback is Shaping the Bayview Community Shuttle

How Your Feedback is Shaping the Bayview Community Shuttle
By Hana O’Neill

A new community shuttle is coming to Bayview-Hunters Point in 2024, and we need your help designing it! The SFMTA is partnering with the California Air Resources Board and nine community-based organizations to launch a dynamic service community shuttle that truly meets your needs. The shuttle is funded through California Climate Investments, a statewide initiative that puts billions of Cap-and-Trade dollars to work reducing greenhouse gas emissions, strengthening the economy and improving public health and the environment — particularly in disadvantaged communities. 

A “dynamic service” shuttle is one that doesn’t have a fixed route like a bus line, but instead operates in a “service area.” The shuttle will pick up and drop off riders throughout the service area, which can help you reach destinations that were previously hard to get to. The Bayview is a geographically isolated community and the community identified the need for a shuttle like this in the Bayview Community Based Transportation Plan. 

We’re currently working on defining that service area. We’ve held 28 events where we talked to almost 2,000 residents, but we know not everyone can come to community meetings or other events. So we also conducted a survey that residents filled out online or on paper at outreach events. We surveyed 629 residents, who gave us 1,060 places they wanted to take a shuttle to. Here’s a summary of the results: 

Many people wanted to take short trips that start and end within the Bayview. 76 people told us that they wanted connections to specific transit lines, such as to the T Third. Others gave destinations that are easily accessible via already-existing Muni lines, such as Chinatown. While a shuttle may not be able to take you all the way to that destination, a direct lift to the T Third would make that trip much easier. 

Desired destination of survey respondents.

 

Initial Service Plan/Alternative A: 

The initial service plan that we presented to residents included service from 7 a.m. to 7 p.m., seven days a week. Riders would wait up to 15 minutes for a ride to Bayview destinations, as well as a few others outside of the neighborhood, such as the 22nd Street Caltrain station, 24th Street BART station and Zuckerberg San Francisco General Hospital.  

Alternative A: Initial conception of service plan.

 

Alternative B: 

How does this plan sound to you? Would you rather have a larger service area for the shuttle so that you could be picked up or dropped off in neighboring areas (shown in gray in the Alternative B map)? This alternative would require running service for a shorter time period – for instance, operating only on weekdays – and with longer wait times. Is this tradeoff worth it? We’d love to hear from you. 

Alternative B: Larger service area and tradeoffs

 

Alternative C: 

We could also run the shuttle for a longer time period, such as from 6 a.m. to 10 p.m., seven days a week, with short wait times – but this would require focusing on local neighborhood connections. The shuttle would serve only the Bayview, with no destinations outside of the neighborhood. 

Alternative C: More service hours and tradeoffs

 

Would you rather be able to go more places, even if that means you wait longer, and the shuttle doesn’t run for as many hours of the day? Or would you rather get a ride more quickly, at more times of day, even if it can’t take you directly to as many locations? Please let us know what you think! 

You can sign up for project updates here to learn about upcoming meetings, including our Community Congress on January 24th. You also can email us at BayviewShuttle@sfmta.com.  

As we continue to do outreach to hear about your priorities, we’re also working to select a company to run this shuttle service. When all is said and done, we’re hoping to start service by the middle of 2024.

Show HN: Slack knowledge curator to extract FAQ from discussion threads https://ift.tt/P1wbXlI

Show HN: Slack knowledge curator to extract FAQ from discussion threads Hi HN! Excited to share Snowshoe, a Slack bot that transforms your Slack threads into a searchable StackOverflow-style Q&A. Snowshoe automatically curates key discussions from Slack, creating a dynamic, easy-to-navigate knowledge hub. A lot of technical discussions among engineers happen in Slack threads. Yet the unstructured thread makes its inherent knowledge difficult for search and thus the discussion insights aren’t often well documented & maintained. LLM is surprisingly good at summarization & extraction. Thus I think it’s good timing to give it a try. Currently Snowshoe focuses on knowledge extraction in Q&A format. What’s next? I feel like there would be a lot of value in the auto-curated Q&A, e.g. auto question answering, knowledge hub, Slack archive for SEO. Happy to hear your thoughts! https://snowshoe.dev/ December 21, 2023 at 12:21AM

Show HN: Canary Checker – An OSS Kubernetes Native Health Check Platform https://ift.tt/CR6SNHz

Show HN: Canary Checker – An OSS Kubernetes Native Health Check Platform I am Moshe the Founder @ Flanksource, and today we are releasing canary-checker, an open source, kubernetes native health check platform that provides a unified view of health across the entire stack. Canary checker was born out of the need for platform teams (particularly those running on- premise or on less than perfect infrastructure) to understand the health of applications running on top of the platform. Unlike other solutions such as prometheus blackbox exporter, kuberhealthy, and synthetic testing offered by major cloud providers, our approach goes beyond health collection. Canary Checker enables health aggregation by ingesting alerts from Prometheus, Cloudwatch, Dynatrace, and for running full test suites using tools like K6, Playright, Robot, etc.. This approach provides a unified view of system health without the need to browse through many dashboards. Canary Checker can also replace the need for multiple Prometheus exporters. It empowers you to export metrics from responses across 35+ supported protocols, including HTTP, SQL and Elasticsearch. Something fairly unique to canary-checker is the ability to build stateful checks that use the results of a previous check in subsequent checks to generate metrics around historical data such as logs, logins, and activity stored in db tables. https://ift.tt/xEciP54 December 19, 2023 at 11:44PM

Show HN: Paradict – Streamable multi-format serialization with schema https://ift.tt/7kKJQSw

Show HN: Paradict – Streamable multi-format serialization with schema Hi HN ! I'm Alex, a tech enthusiast. I'm excited to show you Paradict ( https://ift.tt/4u8SDzM ), my solution for streamable multi-format serialization. Although JSON, YAML, and TOML are all human-readable, they serve different purposes. For example, TOML is specifically designed for configuration files while JSON is used as a data interchange format. Sometimes an initiative to create a binary version of JSON arises and as far as I know, it ends with an unidirectional mapping of datatypes. There is no silver bullet, yet one coherent solution built from scratch that addresses multi-format (binary and textual) serialization and configuration files would be a step forward. Earlier this year, I accidentally designed a textual data format to represent complex data structures inside a document divided into sections. The project, namely Jesth (Just Extract Sections Then Hack'em), generated an interesting discussion on HN ( https://ift.tt/HElnSPR ). Out of curiosity, I ran some benchmarks using Jesth, JSON and MessagePack, with and without Gzip compression against a large JSON file downloaded from the web. The benchmarking gave me insights that led to the decision to evolve Jesth's ideas into a new multi-format serialization solution. I designed and built Paradict from scratch to serialize and deserialize a dictionary data structure. Although Paradict's root data structure is a dictionary, lists, sets, and dictionaries can be nested within it at arbitrary depth. A Paradict dictionary can be populated with strings, binary data, integers, floats, complex numbers, booleans, dates, times, datetimes, comments, extension objects, and grids (matrices). There is also a schema-based validation mechanism that can contain programmatic checkers. The binary serialization format is designed with compactness in mind such as Pi with its first two decimal places, the Golden ratio with its first two decimal places, and the date of the funeral of Pope Benedict XVI would each be encoded on two bytes (not counting their respective 1-byte tag which starts each Paradict binary datum). This binary format has two levels of granularity for continuous data stream processing: a datum at the low level, which is in some cases a 2-tuple composed of a tag and its payload, and the message at the high level which is a dictionary data structure. The textual serialization format has two modes: data and config modes. Config mode implicitly treats dictionary keys as strings, removing the need to surround them with quotes, and unlike the colon (:) between a key-value pair in data mode, it uses the equal sign (=) as separator. This textual format has two levels of granularity for continuous data stream processing: a single line of text at the low level and the message at the high level which is a dictionary data structure. Here is a valid Paradict configuration document that contains a "user" section: [user] # no comment id = 42 name = 'alex' birthday = 2042-12-25T16:20:59Z photo = (bin) 54 68 69 73 20 69 73 20 6E 6F 74 20 61 20 70 68 6F 74 6F 67 72 61 70 68 weight_matrix = (grid) 1 0 1 0 0 1 0 1 1 0 1 0 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. --- Under the hood, Paradict uses Braq ( https://ift.tt/6RjAv9G ), the most obvious way to section a document (as shown just above), and Ustrid ( https://ift.tt/JO3SaGn ), to uniquely generate string identifiers. Paradict is available on PyPI and you can learn more by reading its README, browsing the source code or playing with its tests. Let me know what you think about all this ! https://ift.tt/4u8SDzM December 18, 2023 at 10:00PM

Show HN: Get any piece of Google Earth as a single normalized glTF 3D model https://ift.tt/sOhjtWJ

Show HN: Get any piece of Google Earth as a single normalized glTF 3D model Google released an API in May to get fetch 3D Tiles of anywhere on Earth. Using this in standard 3D engines like Blender is tricky because (1) the tiles are in a geographic coordinate system (2) you get a lot of little tiles at varying quality levels I wanted to simplify this so all you need to do is get an API key, select a map region and a zoom level, and get one combined glTF file that you can throw into any engine. Especially if you're just prototyping and want to see how this data looks in your engine before investing in figuring out all the nuances of the API & coordinate system. (Note that the API prohibits offline use, as in you can't distribute a processed glTF file like this. But you can do this preprocessing in memory whenever you're fetching tiles). https://ift.tt/jLrxPRb December 17, 2023 at 10:07PM

Show HN: Sqlauthz: Declarative permissions management for PostgreSQL https://ift.tt/hFWYOmX

Show HN: Sqlauthz: Declarative permissions management for PostgreSQL I've been working on a little project recently to solve a problem that I've encountered at every job I've ever had, and I'm eager for some feedback. Having super granular roles & permissions in PostgreSQL is desirable, but quite difficult to maintain (particularly at smaller companies without dedicated security/devops/DBA/whatever who make it their business to maintain it). I've thought for a while that having a declarative way to manage them would be really useful and allow more teams to actually make use of sophisticated security features that PostgreSQL offers in their production systems. You can probably see where this is going... I wrote a tool to do just that! It's called sqlauthz, and it allows you to declarative manage your PostgreSQL permissions by writing rules in the Polar authorization language. https://ift.tt/sDYBMjo December 17, 2023 at 12:42AM

Show HN: Octopus – a directed acyclic graph for app development https://ift.tt/NDYoUGV

Show HN: Octopus – a directed acyclic graph for app development Directed acyclic graphs are muched discussed in comp-sci, but octopus appears to be the first reusable, turnkey, ready-to-wear, off-the-shelf implementation of a DAG for application development, in any language, that I'm aware of. This is remarkable because DAGs hit a sweet spot in the middle of the three common programming paradigms (OO, event-driven, functional). Let's have a DAG as the top-level structure of our applications. Data-fetching and onChange handlers live in DAG nodes, next to the data they act on. The UI flows out from the DAG with fine-grained reactivity. Our app state is effortlessly consistent, because any outside change (user action, api result) unleashes a graph traversal. Our UI components become much simpler, because they just need to dumbly reflect values in the graph. I'm putting this up for a second time. Absolutely no-one bit the first time, which can't be right :-) https://ift.tt/bImJ8FY December 15, 2023 at 12:06AM

‘Muni Is My Ride’: A Celebration of Muni Riders and Operators

‘Muni Is My Ride’: A Celebration of Muni Riders and Operators
By Sophia Scherr

Muni is more than just a system of buses, trains, streetcars and cable cars. It's a living entity that pulses through the streets of San Francisco, connecting riders to the neighborhoods and people that they love. In the vibrant pages of "Muni Is My Ride," artist Keith Ferris and writer Lia Smith invite readers to celebrate the soul of Muni.  

The project began as a collection of sketches depicting interesting passengers that caught Ferris’ eye. After a few years, he realized those sketches were something special: a mosaic of people who make up the heart of Muni. Ferris and Smith, who are both passionate about the transit system, found inspiration in each other as the project unfolded. What started as a passenger showcase grew to include portraits of Muni operators.  

Ferris and Smith then embarked on a journey (during COVID no less!) to capture the essence of riding and operating Muni. The pair conducted in-depth interviews and lightning-fast portrait drawing sessions with Muni operators whenever and wherever they could. The interviewing process wasn’t easy at first, as some operators were not eager to open up. However, through word of mouth, a handful of operators agreed to share their stories. The diversity of the operators’ backgrounds and perspectives adds more layers to the narrative of what Muni means to people.  

Ferris and Smith found unexpected joy and serendipity as they were creating the book, making new friendships and improving their marriage, highlighting the magic of Muni in facilitating connections.  

As readers make their way through the pages of "Muni Is My Ride," Ferris and Smith hope they’ll develop a deep appreciation for our system and its dedicated operators and staff.  

“Muni is more than just a mode of transportation,” says Smith. "In a world that can feel increasingly individualistic, Muni offers a chance for people to interact with one another, fostering a sense of community and shared humanity”.  

The authors also encourage readers to recognize the humanity of the operators who provide our city with such an essential service. Ultimately, the book is intended to serve as a reminder of the shared responsibility that binds San Franciscans to their public transit system and to inspire readers and riders to take pride in Muni.  

 “Muni Is My Ride” is the perfect gift for the Muni or public transportation lover in your life this holiday season, as it offers readers a glimpse into the people that make our system so unique. You can find it at the following locations: 

•  Local independent bookstores Bird & Beckett, Christopher's, Dog Eared Books, Fabulosa, Green Apple on the Park, the Market Street Railway Museum, Medicine for Nightmares and the Russian Hill Bookstore 

• Online book sales through The Green Arcade

• The San Francisco Public Library

“120 years: SFMTA Photo Archive 1903-2023” Exhibit Opens Dec. 16

“120 years: SFMTA Photo Archive 1903-2023” Exhibit Opens Dec. 16
By Jeremy Menzies

On Saturday, Dec. 16, a new exhibit featuring photographs from the SFMTA Photo Archive is opening at the Harvey Milk Photo Center with a reception from 2 – 5 p.m. The show,“120 years: SFMTA Photo Archive 1903-2023" taps into twelve decades of image making by photographers working for our city’s transit agencies.  

View east towards Ferry Building on Market Street from 4th Street, October 1, 1948.

Since 1903, the development of San Francisco has been documented through the lens of our transportation system by more than two dozen people. Today, these photographs make up the vast collections in the SFMTA Photo Archive. With well over 100,000 images, the archive is one of the largest repositories of photos focused on our transit network. 

West Portal Station with new Light Rail Vehicles at platform, February 18, 1982. 

From glass plate negatives to digital image sensors, the tools of the trade may have changed, but the work of capturing our city’s ever-evolving transportation system still is much the same. Everyday scenes of San Franciscans traversing the streets, historic moments in our local history and inexplicably beautiful views of normally mundane subjects come alive through the black and white and color prints on display in the exhibit.

120 years: SFMTA Photo Archive 1903-2023 runs from Dec. 16, 2023, through Feb. 3, 2024. The gallery is located at 50 Scott Street on the west end of Duboce Park and is open Tuesday-Thursday 3:00pm-8:30pm and Sat 11:00am-4:30pm. Take Muni Metro, (N Judah, J Church, K Ingleside or M Oceanview), 22 Fillmore, 6 Parnassus, 7 Haight/Noriega or 37 Corbett to get to the gallery.

Show HN: Visualize rotating objects from the 4th, 5th, nth dimensions https://ift.tt/LEU6jI3

Show HN: Visualize rotating objects from the 4th, 5th, nth dimensions Ever since I remember I had a lot of curiosity regarding hyper dimensional spaces. Picturing higher dimensions, such an impossible yet exciting idea... So years ago I came across a small GIF of a tesseract. Since then it left me wondering how cubes from even higher dimensions would look like... Years passed and I became a software developer, decided to tackle the problem myself and ncube was the result. ncube allows you to visualize rotating hypercubes of arbitrary dimensions. It works by rotating the hyperdimensional vertices and applying a chain of perspective projections to them until the 3rd dimension is reached. Everything is generated in real time just from the dimension number. The application is fully free and open source: https://ift.tt/bUtg3Cy . There, you'll find some demos, more detailed explanation and how you can test it out yourself. Binaries for Windows, Mac and Linux are available: https://ift.tt/suwrOSx There's also a web version that runs fully on the browser: https://ncube.ndavd.com If you like the project I'd appreciate if you could give it a star on GitHub ♥ If you have any issue or feature request please submit at https://ift.tt/A9B4czh https://ncube.ndavd.com December 11, 2023 at 11:53PM

Show HN: QA GPT – Write UI tests in plain English powered by GPT-4-Vision https://ift.tt/WYS1VBH

Show HN: QA GPT – Write UI tests in plain English powered by GPT-4-Vision Hey HN, QA GPT enables engineers and QA teams to write UI and functionality tests in plain english. As engineers, we sometimes get a little lazy when it comes to testing the functionality of our changes. It's hard to switch from coder hat to user hat. However, a single bug can significantly impact users experience and satisfaction. Errors found in production aren't just a nuisance; they're costly. The later a bug is discovered, the more expensive it becomes to fix. I built QA GPT as a proof of concept to make writing UI/functionality tests really easy. It's super simple - just write your test case in plain english and run it. For example: - "Test the new sharing functionality by signing in, selecting a user, and clicking share." - "Log in and try adding a product to the cart" - "Create a new card, view the number of the card, and verify the digits match the face of the card" Let me know what you guys think https://ift.tt/9L10S3e December 13, 2023 at 02:54AM

Show HN: RΞASON – Open-source TypeScript framework for LLM apps https://ift.tt/R8KFBYs

Show HN: RΞASON – Open-source TypeScript framework for LLM apps Hi HN! RΞASON is an OSS Typescript framework for developing LLM apps that uses Typescript's interfaces to get structured output from an LLM. While there are other TS LLM frameworks, I think RΞASON fills a unique space in the market: it's laser-focused on only three areas and, most importantly, actively stays away from pre-made prompting & retrieval. I've been in the LLM space since GPT-3 originally came out, and I've always had problems with other frameworks, such as LangChain. I dislike that they focus a ton on out-of-the-box prompting & pre-made agents — I , as the dev, should be the one in charge of it. My belief is that LLMs are a new primitive that programmers can use — not a new way to program; it's still up to the programmer to do the right thing & create the right abstractions. Therefore, it's the developer's job to learn the new concepts that come from this new primitive, such as prompting & retrieval. I see a similar analogy here with ORMs & SQL. What RΞASON helps with is in areas that don't differentiate your app: getting structured outputs, handling streaming, and observability. The goal of RΞASON is to make creating great LLM experiences easier. We try to accomplish this by simplifying the hard stuff & maximizing performance — decreasing as much as possible the TTUB. RΞASON is OpenTelemetry compatible — which allows observability in almost any tool (Zipkin, Jaeger, paid solutions, etc.). I'd really love to hear feedback about RΞASON! It has been a hobby project for the last months and I'm super curious to what y'all will think. By the way, contributions welcome! https://ift.tt/umWzr5s December 13, 2023 at 01:05AM

Show HN: I built an OSS alternative to Azure OpenAI services https://ift.tt/ymAOdjp

Show HN: I built an OSS alternative to Azure OpenAI services Hey HN, I am proud to show you guys that I have built an open source alternative to Azure OpenAI services. Azure OpenAI services was born out of companies needing enhanced security and access control for using different GPT models. I want to build an OSS version of Azure OpenAI services that people could self host in their own infrastructure. "How can I track LLM spend per API key?" "Can I create a development OpenAI API key with limited access for Bob?" "Can I see my LLM spend breakdown by models and endpoints?" "Can I create 100 OpenAI API keys that my students could use in a classroom setting?" These are questions that BricksLLM helps you answer. BricksLLM is an API gateway that let you create API keys with rate limit, cost control and ttl that could be used to access all OpenAI and Anthropic endpoints with out of box analytics. When I first started building with OpenAI APIs, I was constantly worried about API keys being comprised since vanilla OpenAI API keys would grant you unlimited access to all of their models. There are stories of people losing thousands of dollars and the existence of a black market for stolen OpenAI API keys. This is why I started building a proxy for ourselves that allows for the creation of API keys with rate limits and cost controls. I built BricksLLM in Go since that was the language I used to build performative ads exchanges that scaled to thousands of requests per second at my previous job. A lot of developer tools in LLM ops are built with Python which I believe might be suboptimal in terms of performance and compute resource efficiency. One of the challenges building this platform is to get accurate token counts for different OpenAI and Anthropic models. LLM providers are not exactly transparent with the way how they count prompt and completion tokens. In addition to user input, OpenAI and Anthropic pad prompt inputs with additional instructions or phrases that contribute to the final token counts. For example, Anthropic's actual completion token consumption is consistently 4 more than the token count of the completion output. The latency of the gateway hovers around 50ms. Half of the latency comes from the tokenizer. If I start utilizing Go routines, might be able to lower the latency of the gateway to 30ms. BricksLLM is not an observability platform, but we do provide integration with Datadog so you can get more insights regarding what is going on inside the proxy. Compared to other tools in the LLMOps space, I believe that BricksLLM has the most comprehensive features when it comes to access control. Let me know what you guys think. https://ift.tt/aMu71sK December 12, 2023 at 12:26AM

Show HN: MyYogaFlow – Online Yoga Instructor https://ift.tt/CoKrcAh

Show HN: MyYogaFlow – Online Yoga Instructor Hi fellow hackers :) I am an indie hacker based in Switzerland who has been tinkering around with many side projects. Most of the things I developed were for myself or just to get familiar with a specific technology or piece of software. I never really deployed anything so far. Not too long ago, my SO and me bought a deck of cards with different yoga poses on them. Since we both work from our office chairs more than 8 hours a day, we wanted to do something for our body and this is where the yoga idea originated from. After the first 10 minutes of reading through the leaflet and another 30 minutes of choosing the poses and putting them in a somewhat meaningful order, we finally started with our own yoga session. It was clear to me: this is not something my SO wants to do every day. Doing the same order of poses every day wasn't an appealing alternative either. Away with the cards and on the lookout for an alternative again. Hence I started developing an application for us, that automatically generates a yoga session. It shows the poses one by one and guides you through the session. Each session is unique, which makes it more interesting over the days. The app even lets you create your custom flow that you select or it chooses among poses that fit your experience level just right. I have recently launched this application and made it publicly available. It is working (in most of the cases) and we are pretty happy about how it turned out. We used it many times in our lunch breaks or after a stressful day to calm down. I would be more than happy to get some feedback on it and some pointers on what to improve or focus on next. https://ift.tt/Wx7ATgS December 10, 2023 at 08:32PM

Show HN: wallstreetlocal – View investments from the world's biggest SEC filers https://ift.tt/KvxujOW

Show HN: wallstreetlocal – View investments from the world's biggest SEC filers Hello Hacker News! My name is Anonyo, and I am a seventeen-year-old from Southeast Michigan. This is wallstreetlocal, my passion project for the last year. The United States Securities and Exchange Commission (SEC), forces institutional money managers whose portfolios surpass $100 million to quarterly update the SEC website with their latest investments. These money managers, known as 13F (the form type of the report) filers, are the biggest investors in America, and the law forces them to publicly reveal their investments. The problem I found was that SEC filings are cumbersome to find and view. To remedy this, wallstreetlocal saves and formats SEC data by bulk in an easily accessible format. Other websites do the same thing wallstreetlocal does, but wallstreetlocal places an emphasis on stock data. You can compare prices over time, view gains, and even download the data yourself to make any conclusions you wish. For as many stocks as possible, wallstreetlocal provides accurate, recent data to accompany the filings. As of current, there are 850,000 companies in the search database, 30,000 stocks in the stock database, and about 50 filers queried (equates to a couple million lines of JSON, requested by myself alone). By exploring the website, you can see the resources I used, check out some notable money managers I listed, and download any data that suits you. All for free. I plan to open-source this project someday, but I just wanted to get it released for now. The stack uses FastAPI for the back-end, and Next.js for the front-end. The back-end is hosted on a VM using Docker for the different microservices, and the front-end on Vercel. I made this project to better democratize SEC filings, and also to get some experience on my hands. I love computers, and one day hope to change the world through startups. In the comments, I'd appreciate any and all advice, as well as feedback on how to improve the site. Thanks. https://ift.tt/BNUHIXC December 9, 2023 at 11:26PM

Show HN: We've built an Open Source plugin to make using AI easier for VFX https://ift.tt/Uc0BqaF

Show HN: We've built an Open Source plugin to make using AI easier for VFX Hi, I’m Bryan Lyon, the CTO of DeepMake. We’re making plugins for VFX software suites (Right now we have a pre-release of our After Effects plugin ready) that enable you to use Open Source AI tools without leaving the workflow. It makes all the AI tools work just like another plugin in the VFX software. In the past, I worked on VFX adjacent AI and was more than once asked to make AI tools easier to use so the VFX experts could use them. In many cases my job was little more than making it easy to install and make sense to use. After writing dozens of “one-off” scripts that made an AI tool usable I decided there should be a better way. To that end we’ve simplified the process. Right now our public release is still not the easiest to install, but once you’ve installed one plugin and the backend, installing new plugins is as simple as extracting a zip file or cloning a repo (and we’re going to make it even easier). Our target audience isn’t non-technical people, but rather people who don’t have the time or experience to go through installing an AI tool which may not even include an easy way to send your own data through the pipeline. We hope to make VFX easier for people who can’t really do VFX now due to either a lack of time or experience. We also want to make VFX more powerful for VFX experts. We’ve built the backend to make plugins extremely easy to make and hope that the community will be able to take advantage of an easy way to integrate with VFX tools. IN the spirit of open source we’ve released our code as open source (We’re cleaning up the AE plugin side, but it’ll be released too). We plan on monetizing based on managing massive plugins across compute farms for big VFX shops and other features that benefit those larger teams, the core of the system will remain open source and freely available. So far, we’ve released a Stable Diffusion plugin, and have more including Masking, Super Resolution, and more coming up in the pipeline. I hope you like our software and look forward to hearing from you. https://ift.tt/MGgJWbV December 9, 2023 at 03:15AM

Show HN: Online RPG Game with AI being dungeon master https://ift.tt/JsMhtw4

Show HN: Online RPG Game with AI being dungeon master Hi I've created a text-based RPG game in which you can experience different adventures and play interesting characters while the AI acts as a real time DM/story teller. There are multiple ways to interact with AI: 1) Input free will move 2) Input default move (affects resources) 3) Post a question to DM Also one more cool feature is that you can create your own adventure via simple form. Add scenes, add characters and make it public so other players are able to test it. I also plan to have 'competetive' side where players will pay some small fee to creators in crypto depending on community, and leaderboards can determine price pool reward distribution. But thats for future. Check it out and tell me what you think guys :) https://v3rpg.com https://ift.tt/pbM1zQY December 7, 2023 at 01:51AM

Show HN: Lume – automate data mappings using AI https://ift.tt/iWdfSnJ

Show HN: Lume – automate data mappings using AI Hi HN! I'm Nicolas, co-founder of Lume, a seed-stage startup ( https://www.lume.ai/ ). At Lume, we use AI to automatically transform your source data into any desired target schema in seconds, making onboarding client data or integrating with new systems take seconds rather than days or weeks. In other words, we use AI to automatically map data between any two data schemas, and output the transformed data to you. We are live with customers and are just beginning to open up our product to more prospects. Although we do not have a sandbox yet, here is a video walkthrough of how the product works: https://ift.tt/HRDF4yz?... . And, here is our documentation: https://docs.lume.ai . We would love to get you set up to test it, so please reach out. Using Lume: we do not have self-serve yet. In the meantime, you can request full access to our API through the Request Access button in https://www.lume.ai . The form asks for quick information e.g. email so that I can reach out to you to onboard you. Please mention you came from HN and I’ll prioritize your request. How our full API product offering works: Through Lume’s API, users can specify their source data and target schema. Lume’s engine, which includes AI and rule-based models, creates the desired transformation under the hood by producing the necessary logic, and returns the transformed data in the response. We also support mapper deployment, which allows you to edit and save the AI generated mappers for important production use cases. This allows you to confidently reuse a static and deterministic mapper for your data pipelines. Our clients have three primary use cases - Ingest Client Data: Each client you work with handles data differently. They name, format, and handle their data in their own way, and it means you have to iteratively ingest each new client's data. - Normalize data from unique data systems. To provide your business value, your team needs to connect to various data providers or handle legacy data. Creating pipelines from each one is time consuming, and things as small as column name differences between systems makes it burdensome to get started. - Build and maintain data pipelines. Creating different pipelines to that map to your target schema, whether for BI tooling, downstream data processing, or other purposes, means you have to manually create and maintain these mappings between schemas. We're still trying to figure out pricing so we don't have that on our website yet - sorry, but we wanted to share this even though it's still at an early stage. We’d love your feedback, ideas & questions. Also, feel free to reach out to me directly at nicolas@lume.ai. Thank you. https://www.lume.ai/ December 6, 2023 at 11:07PM

Show HN: Frogtab – Private, peaceful task management https://ift.tt/eVW9l2t

Show HN: Frogtab – Private, peaceful task management Hi HN! I'm excited to share the task manager that I've been building and relying on for the past 9 months I started developing Frogtab after a particularly busy period at work, where a large number of ad-hoc tasks would need my attention each day. What I Initially tried was a single (long!) checklist of outstanding tasks, but I found that too overwhelming to look at all day long. Then I tried scheduling tasks based on when I expected to complete them, but that also required too much cognitive load - I only had the capacity to bucket tasks into "today" and "not today" And so Frogtab was born. Originally as a Google doc, then later as a rudimentary web app with some simple automation. The automation was there to nudge me towards good habits, e.g., grouping all my outstanding tasks at the beginning of each day and requiring me to consciously choose which tasks to tackle that day. I subsequently refined the system a little, but the core mechanic has been serving me well ever since! More than the benefits I've gotten from using Frogtab at work, it's been really fun to develop Frogtab into a form that is usable - dare I say enjoyable - by other people too. Thanks to feedback from the awesome community at Bear (bearblog.dev) and also from sharing an early version here on HN, I've been able to make a whole host of improvements to Frogtab Highlights include: - Support for a weekly routine, aka recurring tasks - Data export and import, including auto-backup in supported browsers - Ability to receive tasks sent from any device - Dark theme - Keyboard shortcuts - Full docs at frogtab.com/help As I've been developing Frogtab, one of my primary concerns has been data privacy. Frogtab stores data in your bowser and doesn't require an account. Also, Frogtab does not use cookies, collect PII, serve ads, or track you in any way. It's entirely free to use and fully open source - the code is at github.com/dwilding/frogtab If you try Frogtab, I hope that you have a great experience! I would love to hear any feedback/suggestions, thank you :) https://frogtab.com/ December 6, 2023 at 04:27AM

Show HN: Solving NYT Connections with ChatGPT https://ift.tt/edM1NhF

Show HN: Solving NYT Connections with ChatGPT Just for fun I decided to see if I could use chatGPT to solve NYT Connections word puzzles. It uses a pretty straightforward BFS search in which the LLM is first prompted to generate several possible groupings of four related words, and then a different prompt is used to evaluate the soundness of each of those groupings. This approach seems to be able to produce the correct solution somewhat less than half the time. Some observations: * For whatever reason, chatGPT-4 seems to be a bit worse than 3.5 at generating Connections groupings. I haven’t tested systematically so maybe this is just some small sample size bias. But at the very least it isn’t obviously better * It really struggles with the “words that can fill in the blank” style groups. Often it will correctly come up with the right category (e.g. “words that can precede `cheese`”) but will only be able to identify 2 of 4 words in that grouping * It frequently generates very vague categories (“words that can be nouns”) despite nothing like that appearing in the proposal prompt. Also it will still sometimes score them highly, despite there being several explicitly examples in the value prompt disallowing these types of categories If you have any idea for how to improve this, please let me know (or send a PR)! https://ift.tt/Ir3yFLS December 6, 2023 at 01:41AM

Show HN: Dropbase – Build internal web apps with just Python https://ift.tt/b85noGF

Show HN: Dropbase – Build internal web apps with just Python Hey HN, I’m Jimmy, co-founder of Dropbase ( https://www.dropbase.io ). We are an internal tools builder for Python developers. All you have to do is import any Python scripts/libraries, declare UI components, and layer app permissions so you can share them with others. We’re a middle ground between Airplane and Retool—simpler UI creation than Airplane, more code-centered than Retool. UI building is declarative and you can bind Python scripts/functions to UI components. You can write Python scripts/functions using our App Studio with support from a Python Language Server Protocol (LSP) for linting. Since the self-hosted worker directly references .py or .sql files in the filesystem, you can even write them on VSCode directly or import any other Python script or library. Our app layout is highly opinionated to speed up app building. Instead of an open canvas for UI building, we just give you a main table view and a widget sidebar. This approach significantly reduces app-building time while still covering what most tools need: see some data and take actions based on it. It’s not flexible enough to do absolutely anything, but that’s the point—there’s a tradeoff between flexibility and speed. Dropbase gives you most of what you need, plus speed! A neat feature we are experimenting with to build admin panels fast is “Smart Tables”. We convert any SQL SELECT statement (even across multiple joins and filters) into an inline editable table, like spreadsheets, without any additional code. We have a hybrid hosting model that combines a self-hosted client and a worker server, with a backend API for app/component definitions hosted by us to simplify pushing feature updates. The worker server sits in your machines so your sensitive data doesn’t leave your infra. We’re Python-centric for now, but plan to add support for Rust, Go, and others later. We made a few demo videos building common tools: - Customer approval tool: https://youtu.be/A1MIIRNkv3Q - Data editing tool (with Smart Table): https://youtu.be/R1cHO9lMRXo To try Dropbase, create an account at https://app.dropbase.io and generate a token, then follow these instructions for local setup: https://ift.tt/awNGC3u . We are very early so we're really excited to get your feedback, especially on our approach to tools building with Python! My co-founder Ayazhan and some of our teammates will be around to answer questions. https://ift.tt/BDNv5bq December 5, 2023 at 11:55PM

Show HN: Satounki – Self-hosted temporary elevated access management service https://ift.tt/nhOZ4We

Show HN: Satounki – Self-hosted temporary elevated access management service I was reading through the comments on this HN post last night[1] which inspired me to share this project here today. I've been working on Satounki since I got laid off last month. It's the culmination of a lot of experience building similar ad-hoc internal tooling at various places throughout my professional career. Satounki already includes: * AWS support * GCP support * Cloudflare support * Auto-generated Terraform providers from the Rust API * Auto-generated Typescript client wrapper from the Rust API * Slack bot for request notifications, approvals and rejections * CLI for requests, approvals and rejections * Dashboard for exploring policies, requests and stats The scope of this project is pretty big and I'm looking for contributors; if you know Rust, Go, Typescript, Nix, or even have an interest in them, take a look and see if this is something that you might like to work on!

Show HN: Audio plugin for circuit-bent MP3 compression sounds https://ift.tt/3ZAo0Gf

Show HN: Audio plugin for circuit-bent MP3 compression sounds I made MAIM, an open-source audio plugin that uses real MP3 encoders to distort the sound. I've also added knobs that let you "circuit bend" the encoders, changing parameters that would normally be inaccessible to the user to get strange glitchy sounds. The plugin lets you switch between two MP3 encoders, since under the MP3 standard, the specifics of what to lose in MP3 lossy compression is left up to the encoder. The encoders are LAME, the gold standard for open-source MP3 encoders, and BladeEnc, an old open-source MP3 encoder that has a really bubbly sound and was fun to work with. I'd love any feedback, and I'll be around to answer questions! https://ift.tt/3eswfbk December 3, 2023 at 11:31PM

Show HN: Bi-directional sync between Postgres and SQLite https://ift.tt/UCgemAH

Show HN: Bi-directional sync between Postgres and SQLite Hi HN, Today we’re launching PowerSync, a Postgres<>SQLite bi-directional sync engine that enables an offline-first app architecture. It currently supports Flutter, React Native and web (JavaScript) using Wasm SQLite in the browser, with more client SDKs on the way. Conrad and I (Ralf) have been working on our sync engine since 2009, originally as part of a full-stack app platform. That version of the system is still used in production worldwide and we’ve learnt a lot from its use cases and scaling. About a year ago we started on spinning off PowerSync as a standalone product that is designed to be stack-agnostic. If you’d like to see a simple demo, check out the pebbles widget on the landing page here: https://ift.tt/7kELyRZ We wrote about our architecture and design philosophy here: https://ift.tt/tFsoAcE... This covers amongst other things how we designed the system for scalable dynamic partial replication, why we use a server authority architecture based on an event log instead of CRDTs for merging changes, and the approach to consistency. Our docs can be found here: https://ift.tt/GpTI4fx We would love to hear your feedback! - Ralf, Conrad, Kobie, Phillip and team https://powersync.com November 30, 2023 at 07:43PM
