Show HN: ParallelGPT – Batch processing with ChatGPT on low-code spreadsheet UI We made ParallelGPT - a tool that lets you bulk process chatGPT on a spreadsheet UI instead of one-by-one conversation style. Hopefully this saves you time and hassle - especially if you want to build an operational process around it and want to collaborate your team. You can give it a quick spin on this live demo playground: https://ift.tt/UTfGIJs... I am the co-founder of Rowy( https://www.rowy.io ), an open-source low-code platform, and we built ParallelGPT as a fun showcase of what you can do with low-code. There are tons of exciting AI apps you can build with low-code, and we're always happy to chat about any ideas you have and assist on our Discord. https://ift.tt/udXFEY5 April 1, 2023 at 07:47AM

Show HN: Simply explain 20k concepts using GPT Hi HN! I made a tool that autogenerates simple, high-level explanations of concepts and organizes them in a somewhat university course-like structure so that it's easier to see how things are structured. Currently it has about 20,000 concepts on a range of topics but that's just what I generated so far, it should work with more obscure topics in the future. I love learning about random topics where I don't have a good background in like history or linguistics, but it's hard to figure out what topics there (you don't know what you don't know) are in certain fields and what they are even about, so this was a way to get the high level idea about random things that I wanted to know about. It also only uses the information in the GPT model at the moment, so obviously information can't be trusted completely and you should definitely double check any information you read here by Googling. I'm thinking of doing the

Show HN: Cadseer. a parametric solid modeling CAD desktop application Cadseer is in the same genre as: solidworks, inventor, freecad etc... Cadseer is alpha software, so lots of missing features, bugs, crashes, file incompatibilities etc... About me: I spent 15 years designing stamping dies on a high end cad system. During that time, I also developed and marketed extensions/plugins toward that cad system. Through that experience, I came disillusioned with 'vendor lock-in' and proprietary software in general. I basically retired, took the vow of poverty and moved all my computing to open source. I have since, and continue to, try and improve the open source cad environment. https://ift.tt/1PDg5zo April 1, 2023 at 01:35AM

Show HN: Kaskada – modern, open-source event processing We recently open-sourced Kaskada – an event-processing engine built on Rust and Apache Arrow. It features a high-level, declarative query language designed specifically for reasoning about events in bulk and in real time. Unlike SQL, an aggregation over events produces a timeline indicating the value at each point in time over the events that have occurred up to that point in time. The query language provides composable, expression oriented syntax, including the ability to nest aggregations. Due to the focus on events and temporal queries, it provides capabilities to shift events forward (not backward, to avoid "leaking" information about the future into past values), ticks that create new times (allowing you to observe the current value of an aggregation every day, for instance) and joins that operate "at the current time". Example query: # Purchases up to a point in time let purchases_now = count(purchase) #

The Municipal Railway Planning Division & The First 5-Year Plan By Kelley Trahan The San Francisco Municipal Railway 5-Year Plan, 1979-1984 was the first comprehensive service plan created by the first San Francisco Municipal Railway transportation planners. The plan introduced a grid system to provide more efficient crosstown service with better neighborhood connections that would improve access and increase ridership, moving away from Muni’s prior service design focused on trips to and from downtown. It also provided service standards, including coverage, capacity and stop spacing, many of which continue to inform Muni planning efforts today. The San Francisco Municipal Railway saw many changes at this time, including the opening of the Muni Metro, the conversion of some lines from diesel to electric trolley bus, a simplified fare structure and increased fares and historic streetcar service on Market Street.  Prior to the mid-1970s, the San Francisco Municipal Railway’s servi

Show HN: Nextflick.io – Watch a random movie trailer I want to introduce Nextflick to you, a website I made showing you a random movie trailer, so you can find out what to watch next. Technically, Nextflick is a rather simple website. Everything is rendered on the server-side. Movies are scraped from the TMDB API and dumped into a NoSQL database. When you request a page, a random movie is selected and it shows you a YouTube embed with a respective trailer. Even though this may seem like such a simple tool, I am immensely proud of it. It is my first project I ever actually shipped, and I had this idea in my head for over 5 years. Sadly I am suffering from a bad load of perfectionism, which always got in the way of finishing anything, until today. I deliberately chose to create something that is small and straightforward. I chose Go as a language because it helps me enormously to "get sh*t done". I don't have to think about too many language constructs or idiomatic ways of

Show HN: Mirrorful – A developer-first way to implement designs faster Hey HN! Mirrorful ( https://ift.tt/d4TQ3mn ) is an open-source developer framework that helps front-end engineers manage their design systems. We’ve been building Mirrorful with the open-source community ( https://ift.tt/t6OUYlw ) and wanted to share our beta with you. Check out our online demo to get the idea: https://ift.tt/m5kh2uQ . Design systems can be thought of as the “building blocks of your app” which makes me think of Lego bricks. Mirrorful helps you manage your codebase’s Lego bricks and ensure that they are consistent across all of your apps and platforms. We saw as product engineers how hard it is to get code to match Figma mock ups. High-quality design is a competitive advantage, so getting your UI pixel perfect can matter a lot, but is time-consuming and tedious. When we worked for large public companies, we saw that good component libraries help, but engineers are often still dealing with tweaking sm

Equations we are used to think as unplottable (with usable real-time performance), like for example `e ^ (sin(x) * x ^ 2 * cos(y)) = cos(e ^ (x * y))`, will render just as smoothly [0] as something simple, like `y = x ^ 2`. Goals: * Rendering (almost) any equation without performance problems * Enabling acquiring new insights from being able to closely interact with complicated equations * Having an intuitive, easy-to-use and not-buggy interface Non-goals: * Being a general-purpose CAS software KGraph is under active development, and features such as parametric equations are coming in the near future!

Background: Last week, FTX published 1.3M anonymized user accounts in a Schedule F filing that lists the unsecured creditors they know about. 1.3M is a huge number, but it may be less than half of the total users FTX had. If your account is not listed, file a proof of claim with the bankruptcy court, or they may not treat you as a creditor (Federal Rules of Bankruptcy Procedure: Rule 3003). The data was uploaded as a series of PDFs, which makes it hard to find your claim, especially if you don’t remember the exact amounts you had and have to fuzzy match with cmd+f! We built FTX Creditor so that you can find your claim with the information you have. Features: - Find claims by: - Assets.

Accessible version of the expansion of red transit lanes:  Red Transit Lanes Over Time in San Francisco from 2013 to 2023  There is nothing quite like looking out the window at gridlock traffic while your bus coasts down a red transit lane. This may feel like an “only in San Francisco” pleasure – after all, San Francisco was one of the first U.S. cities to “roll out the red carpet” by painting bus lanes red. But red transit lanes have now become a popular way to keep buses out of traffic in more than 25 cities across the country.  The SFMTA is celebrating a decade since the installation of San Francisco’s first red transit lane on Church Street on March 23, 2013 .

Show HN: Open-source MongoDB Atlas alternative public beta We have built an alternative to MongoDB Atlas that is open source, provides automatic database sharding and strong data consistency, and can scale to millions of records read and written per second and petabytes of data storage at a fraction of the cost. The first beta release of our MongoDB compatibility offers support for MongoDB 6.0+ CRUD and Aggregation operations. Any application that uses the supported MongoDB CRUD and Aggregation operations, no matter the programming language, can now use Tigris instead of MongoDB Atlas. https://ift.tt/8Ky9g41 March 22, 2023 at 12:16AM

Show HN: Great Books Homeschool beta program I built this customizable literature-based K-12 homeschool curriculum, based on my experience as a homeschool parent. It's designed especially for intellectually curious kids who love to read. One of the main benefits of homeschooling is the ability to design customized programs of study that let kids learn at their level of challenge in each subject. But since designing custom curricula from scratch requires a huge time commitment and familiarity with children's literature and academic materials, most homeschooling parents don't take advantage of this potential and instead opt for prepackaged curricula. Great Books Homeschool eliminates a lot of the work involved in designing a complete and rigorous curriculum for homeschooled students. The website generates a default program of study for each student, then helps parents customize it. Transcripts and other records are generated automatically. Pricing is normally subscription bas

Show HN: I want to change how people buy health supplements I made a table where you can find out the source/location of factory for where health supplements are made. Then, I spent a year reading product labels so you can save time and money when buying supplements. This is that update. This is still a work in progress but it functions fine. My previous post was a simple database of company data showing ingredient sourcing/location. That took 10 days, this has taken me close to 9 months. BackOfLabel is an extension of that initial interest with dosage information at the product & ingredient level. This update allows sorting by many more attributes at the product level (for 4000+ products at the moment) of manually scraped data. Now, for instance you can sort by specific types of ingredient - eg. filter by magnesium glycinate , magnesium orotate or any combination. eg. find ubiquinol or ubiquinone, two forms of coenzyme q10.

San Francisco’s Transit-First Policy Turns 50 By Melissa Culross Transit on Market Street in downtown San Francisco, 2018 It’s been a half-century since the San Francisco Board of Supervisors put transit needs above all other traffic initiatives, and now, the city’s Transit-First policy is celebrating its golden anniversary. The policy guides the city’s work on major infrastructure projects and planning efforts. Its principles drive San Francisco officials to promote incentives that reduce traffic congestion and solo vehicle trips, support transit investments including the purchase of Muni buses and light rail vehicles, and regularly evaluate how well our transportation network functions.  Adopted on March 19, 1973, the original Transit-First policy was born out of an effort to reshape the Municipal Railway so it could serve San Franciscans' needs more effectively. The goals were very specific:  Create exclusive bus lanes and prohibit automobiles from streetcar and cable c

Show HN: Musikalia, an iOS Music Player for Kids Hi HN! Yesterday I finally released Musikalia, an iOS music player I built for my son, so he could be in charge of the music. It is my first SwiftUI project, and I have been (very) slowly building it since December '21. It aims to be fun and easy to use for small children, while not being another addictive app. We are using it almost daily, and in our (n=1) experience, it achieves just that: my 3-year-old loves to listen to music using Musikalia, but at the same time it never feels like he has problems leaving it again.

Show HN: Mr. Graph. A graph deifnition and execution library for Python What: Mr. Graph is a python library designed to make composing graphs of sync and async functions easy! Use google style docstrings to automagically create dataclasses and chain together function calls into graphs. Why: I like the design of Dagster, but not the latency. For apps and systems engineering, sometimes I want to compose a graph out of regular python functions. I don;t need all the heavy machinery that comes with a full workflow engine. Current features: - Use with either async or sync functions - Uses google style doc strings to name return values. - Creates dataclasses for each function's output. - Can infer pipelines from input and output signatures - All directed acyclic graph layouts supported. linear, fan-in, fan-out. Future Features: - Better examples for use with async calls (like LLMs) - Splitting dataclasses, better error handling, logging improvements. This is under active development. Any

Show HN: Quality News – Towards a fairer ranking algorithm for Hacker News Hello HN! TLDR; - Quality News is a Hacker News client that provides additional data and insights on submissions, notably, the upvoteRate metric. - We propose that this metric could be used to improve the Hacker News ranking score. - In-depth explanation: https://ift.tt/bVZDG82 The Hacker News ranking score is directly proportional to upvotes, which is a problem because it creates a feedback loop: higher rank leads to more upvotes leads to higher rank, and so on... → ↗ ↘ Higher Rank More Upvotes ↖ ↙ ← As a consequence, success on HN depends almost entirely on getting enough upvotes in the first hour or so to make the front page and get caught in this feedback loop. And getting these early upvotes is largely a matter of timing, luck, and moderator decisions. And so the best stories don't always make the front page, and the stories on the front page are not always the best. Our proposed solution is to use upvo

I miss the days of things like the YouTube dislike bar, where you can quickly assess if something is good or not. Currently sitting at ~90 users. To get it off the ground I've scraped the last year of HN to make a set of good links, and used a few content farm blacklists to make a set of bad links. Right now it's semi-useful and should only get better with time. There are some simple measures in place to prevent spam & abuse, but will cross that bridge if it ever comes.

Since 2019, we've been working on Nabla (https://www.nabla.com), an intelligent assistant for health practitioners. When GPT-3 was released in 2020, we investigated it's usage in a medical context[0], to mixed results. Since then we’ve kept exploring opportunities at the intersection of healthcare and AI, and noticed that doctors spend am awful lot of time on medical documentation (writing clinical notes, updating their EHR, etc.). Today, we're releasing Nabla Copilot, a Chrome extension generating clinical notes from video consultations, to address this problem.

Tech Talk: Muni Predictions 101 By Christopher Ward New Customer Information Systems are being installed and causing customer curiosity!  Got a burning question about the SFMTA’s Muni predictions that are made by our Next Generation Customer Information System (CIS)? We’ve got answers! Below are some of the frequently asked questions from Muni customers. Send us yours!  Where do Muni predictions come from?   Muni predictions come from data provided by multiple SFMTA systems including equipment on our vehicles. Real-time predictions are based on the real-time locations of Muni vehicles. A computer algorithm compares the real-time data to past travel times based on time of day, day of week, season and other factors that affect travel to predict future arrival times. Travel patterns in this historic data are applied to real-time data to generate accurate Muni predictions.  When the system has no real-time information, it uses Muni schedules to make predictions. This often occurs at
