Show HN: Calculator for US Individual Income tax, from 1970-present https://ift.tt/KUTsWV7

Show HN: Calculator for US Individual Income tax, from 1970-present I wanted to share a simple web app I created recently, which lets you estimate income taxes owed in the US: https://taxsim.app All the calculations occur directly in the browser, and are powered by a Fortran program that has been converted to WASM using emscripten. This calculator was originally developed in the 1970s [1] by the non-profit National Bureau of Economic Research. NBER has been maintaining this F77 codebase for the last 50 years, and uses it primarily for academic research on tax policy. The Fortran source code itself is over 1MB of text, because it codifies both federal and all 50 states' tax laws for each of the last 62 years. I first learned about NBER TAXSIM [2] a few months ago via an interesting paper they published "Automatic Tax Filing: Simulating a Pre-Populated Form 1040" [3]. The Fortran code itself is not open-source, but is available on request for research purposes. I reached out to NBER and proposed compiling it to WASM, so it could be run directly in a browser. With relatively little effort I was able to create a js/wasm version [4], thanks in huge part to previous open-source work [5]. This WASM build now powers https://taxsim.app, which is my attempt to create an interactive UI to allow for easier exploration of the US tax code. Specific tax scenarios can also be shared easily, by simply copying the browser URL. The code for this webapp is also open-source [6]. This was my first time experimenting with WASM, and I am already a huge fan. Not only was I able to take a 60 year old codebase and get it working on every modern browser and device, this work is also now benefiting the academic community. For example, the js/wasm can be run directly in V8, which means it can also now be run locally within R using libv8 [7]. Previously most researchers were uploading their tax scenarios to NBER's servers via ftp/ssh/http.

Show HN: Ploomber Cloud (YC W22) – run notebooks at scale without infrastructure https://ift.tt/TIEu4vH

Show HN: Ploomber Cloud (YC W22) – run notebooks at scale without infrastructure Hi, we’re Ido & Eduardo, the founders of Ploomber. We’re launching Ploomber Cloud today, a service that allows data scientists to scale their work from their laptops to the cloud. Our open-source users ( https://ift.tt/RbXa0Zc ) usually start their work on their laptops; however, often, their local environment falls short, and they need more resources. Typical use cases run out of memory or optimize models to squeeze out the best performance. Ploomber Cloud eases this transition by allowing users to quickly move their existing projects into the cloud without extra configurations. Furthermore, users can request custom resources for specific tasks (vCPUs, GPUs, RAM). Both of us experienced this challenge firsthand. Analysis usually starts in a local notebook or script, and whenever we wanted to run our code on a larger infrastructure we had to refactor the code (i.e. rewrite our notebooks using Kubeflow’s SDK) and add a bunch of cloud configurations. Ploomber Cloud is a lot simpler, if your notebook or script runs locally, you can run it in the cloud with no code changes and no extra configuration. Furthermore, you can go back and forth between your local/interactive environment and the cloud. We built Ploomber Cloud on top of AWS. Users only need to declare their dependencies via a requirements.txt file, and Ploomber Cloud will take care of making the Docker image and storing it on ECR. Part of this implementation is open-source and available at: https://ift.tt/JOMtgTU Once the Docker image is ready, we spin up EC2 instances to run the user’s pipeline distributively (for example, to run hundreds of ML experiments in parallel) and store the results in S3. Users can monitor execution through the logs and download artifacts. If source code hasn’t changed for a given pipeline task, we use cached artifacts and skip redundant computations, severely cutting each run's cost, especially for pipelines that require GPUs. Users can sign up to Ploomber Cloud for free and get started quickly. We made a significant effort to simplify the experience ( https://ift.tt/CfML26D ). There are three plans ( https://ift.tt/OiTGn1R ): the first is the Community plan, which is free with limited computing. The Teams plan has a flat $50 monthly and usage-based billing, and the Enterprise plan includes SLAs and custom pricing. We’re thrilled to share Ploomber Cloud with you! So if you’re a data scientist who has experienced these endless cycles of getting a machine and going through an ops team, an ML engineer who helps data scientists scale their work, or you have any feedback, please share your thoughts! We love discussing these problems since exchanging ideas sparks exciting discussions and brings our attention to issues we haven’t considered before! You may also reach out to me at ido@ploomber.io.

Show HN: ColorTiles Browser Game https://ift.tt/m2CGniT

Show HN: ColorTiles Browser Game Hello HN! Here is a little game I made, colorful tiles must be placed next to other tiles and match in symbol or color. This game is inspired by Passage 3 and similar games like Qwirkle, Rummy or Dominoes. There exist some browser-based versions here and there, but I wasn't completely satisfied with any of them, so I made my own. This is optimized for a broad range of screen sizes and auto-rotates the playing field for narrow (portrait) viewports. As I've discovered with my own parents, folks who enjoy playing Solitaire, Hearts and similar games might enjoy this as well, so gladly spread the word. Have fun and feedback is appreciated! :) https://colortiles.net/ June 29, 2022 at 09:38PM

Show HN: Inngest – an open-source event-driven queue https://ift.tt/ByheEFS

Show HN: Inngest – an open-source event-driven queue Hi HN! We’re Tony and Dan, the founders of Inngest - https://www.inngest.com. We’re an event-driven queueing system. Existing queueing solutions have pretty terrible UX. We solve this by making it simple for you to write delayed or background jobs by triggering step functions from JSON-based events. At a high level, Inngest does two things: - Ingest events from your systems via HTTP (pun intended) - Triggers serverless functions in response to specific events — async, either immediately or delayed. This allows you to build out async functions (eg. background jobs, handling webhooks) much faster, without worrying about config, queues, scaffolding, boilerplate, or infra. Because of the decoupling, it also means cleaner code. We talk about the benefits here [1]. Previously, Tony ran engineering at https://ift.tt/YOfQqzB and Dan was the CTO of https://buffer.com/. At both places, we had to build and manage a lot of complex async logic. You could say that Buffer is one big queue, and at Uniform we had lots of logic to run for compliance… managed via queues. So we're very familiar with the problem. Technicals and how it’s different: Functions are declarative. They specify which events trigger them, with optional conditionals. This is great because you can then deploy functions independently from your core systems, and you get things like canary deploys, plus immediate rollbacks. Each function can have many steps, represented as a DAG. Each step can be any code — an AWS function, custom code in a container, an HTTP call, etc. Edges of the DAG can also have conditions for traversal, and can “pause” until another event comes in, with TTLs and timeout (eg. after signup, run step 1, wait for a user to do something else, then run the next step). Because the functions are event driven, we also statically type and version events for you. This lets you inspect and generate SDKs for events, or to fail early on invalid data. It also lets you replay functions, test with historical data, or deploy functions and re-run historical events. Architecturally, we’ve focused on simple standards that are easy to learn and adopt. Events are published via HTTP requests. Functions use args & stdout. You can get started without knowing any implementation details. You only need to send events via POST requests and write functions that react to them — nothing else required. What people use us for: - A replacement for their current queueing infrastructure (eg. celery). - Running functions after receiving webhooks - Running business logic when users perform specific actions (eg. publishing things at a specific time) - Handling coordinated logic (eg. when a user signs up, wait for a specific event to come in then run another step) Where we’re at: We’ve open sourced our core execution engine [2], which allows you to run an in-memory environment locally with a single command. We’re working on opening more and more of the platform to allow you to self host — that’s currently our main goal. Right now, you can use us “serverless”. Because we record function state, we charge per ‘step’ of a function invoked. We’ve documented our core OS architecture [3], and we’ve also released the function spec and interfaces in our repo. We’ve talked more about about goals, vision, and why in our open sourcing post [4]. There’s also a minimal demo w/ a Next.js backend [5]. We know we’re far from feature complete. There’s so much more we can do. If there’s things you’d like to see, feedback, or improvements, please let us know — we’d love to hear from you and make this better, and get your initial thoughts.

Show HN: I ranked news websites by speed https://ift.tt/OSR3Eoa

Show HN: I ranked news websites by speed I've been working on building "the fastest news website" for a few reasons: 1. I got tired of waiting for news websites to load, so I made a text-only news website that only has major news headlines. 2. I wanted to demonstrate to the world that if you want to build something really fast on the web, you can do it without loads of JavaScript. 3. I wanted to show that you can design something that looks good without having tons of images, etc. I put together the speed page at https://ift.tt/kGp1fKo to hold my website to be more accountable for speed, but it's also interesting to see how fast other news websites are (or in most cases, are not). Some feedback I'm interested in receiving: 1. What's your take both on the speed ranking methodology for Legible News? 2. Are my descriptions of the metrics for a non-web developer reasonable? Example of that at https://ift.tt/Sf0KWAI , and if you click through the links on that table, you see a description like https://ift.tt/MgOnhJY Sorry ahead of time, but I can't fit all news websites on the speed report. I had to target general news websites, not ones for specific niches like HN for Tech. If there's something you think that's missing please post it, but I can't promise that I'll add it. If you like it, please consider subscribing! Thanks! https://ift.tt/kGp1fKo June 29, 2022 at 12:35AM

Show HN: Product Analytics in SQL with dbt Hey everyone! Like many data analysts and engineers, I love SQL and the dbt ecosystem. So it bothers me that we have to use separate tools for product analytics. We do our transformations, BI work, and ad-hoc queries in SQL, but when it's time to look at funnels and flows, we have to use (and procure) a separate platform like Mixpanel or Amplitude. This dbt package is a (very rough) start at fixing that. With it, you can create event streams and run funnel analyses via dbt[0]. More features like flows and retention are coming soon! But I'm mostly curious how you all are doing product analytics right now. Are you using a dedicated tool like Amplitude? What could be better? Do you want to do product analytics in SQL in the warehouse or would you rather it live somewhere else? Would love to get your thoughts, and thanks for taking a look! --- 0.

Details on Expanded Bus Service Coming July 9

Details on Expanded Bus Service Coming July 9
By Mariana Maguire

Photo caption: The 6 Haight-Parnassus is one of the Muni bus routes that will be brought back into service July 9, 2022 after being temporarily suspended since March 2020.

On July 9, the next phase of the 2022 Muni Service Network plan will go into effect, focused on expanding bus service including the return of the 2 Sutter, 6 Haight-Parnassus and 21 Hayes (with some route changes), as well as other route extensions and modifications.

Public feedback helped us prioritize bringing back routes and connections many communities rely on. Read more about what we heard from the public and how we incorporated feedback into the 2022 service proposal.

As resources allow, our service changes will continue prioritizing service linking neighborhoods identified by our Muni Service Equity Strategy to essential destinations like hospitals and neighborhood commercial corridors, accommodate changing travel patterns and getting the most of our system. We heard from many seniors and people with disabilities that bringing back the connection to the Jewish Community Center food hub is an important priority, so we are bringing back the 2 Sutter between Presidio Avenue and California Street and the Ferry Plaza at Embarcadero. For service west of Presidio Avenue, customers can take the 1 California, which runs more frequently one block north of Clement Street.

Restored Routes

Route	Details	Frequency
2 Sutter	Restore pre-pandemic route between the Ferry Plaza and Presidio Avenue at California Street, restoring connections to the Jewish Community Center food hub.	Every 20 minutes
6 Haight-Parnassus	Restore pre-pandemic connections in response to community feedback.	Every 20 minutes
21 Hayes	Restore modified pre-pandemic route from St. Mary’s Hospital to Grove and Hyde streets, by Civic Center Station and the Main Library.	Every 20 minutes

Modified Routes

Route	Details	Frequency
23 Monterey	Extend to pre-pandemic route along Sloat Boulevard to the San Francisco Zoo and Great Highway in response to community feedback.	Weekdays every 20 minutes Weekends every 30 minutes
28 19th Avenue	Extend east of Van Ness Avenue at North Point Street to run between Daly City BART and Powell at Beach streets, providing connections to Fisherman’s Wharf to customers on the westside of the city and who are no longer covered by the 49 Van Ness-Mission.	Weekdays every 12 minutes Weekends every 15 minutes
43 Masonic	Extend north of Presidio Avenue at California Street to the Presidio, the Marina and Fort Mason on its pre-pandemic route between Fort Mason and Munich Street at Geneva Avenue in response to community feedback.	Weekdays every 12 minutes Weekends every 20 minutes
49 Van Ness-Mission	Shorten to its previous route between City College and Van Ness Avenue at North Point Street.	Weekdays every 6 minutes Weekends every 8 minutes
57 Parkmerced	Extend from Eucalyptus Drive and Junipero Serra Boulevard to West Portal Station, restoring the connection to West Portal.	Every 20 minutes
58 Lake Merced	Modify to run along Lake Merced Boulevard instead of Sloat Boulevard and Brotherhood Way instead of John Daly Boulevard, from Mission Street and Daly City BART to Stonestown.	Every 30 minutes
66 Quintara	Return to pre-pandemic alignment terminating in the Inner Sunset.	Every 20 minutes
L Bus	Shorten route to run between the SF Zoo and West Portal Station and increase frequency in response to changing trip patterns.	Weekdays every 8 minutes Weekends every 10 minutes

Looking Ahead

We plan to continue implementing the approved 2022 Muni Service Network in additional phases as we bring more operators onboard. Read more about the complete 2022 Muni Service Network plan.

Show HN: Nerd Crawler – we monitor original comic art sites so you don't have to I've been a fan of comics since I watched the X-Men Animated Series in the 90s, and I fell in love with collecting original comic art when I got my first Jim Lee sketch in high school. But, after missing out on some original comic art pieces because I didn't know when they were added for sale on websites, I decided to take it upon myself to make an app that monitors original comic art sites and emails/texts you when new art drops. It's called Nerd Crawler and I'm building it myself so there might be some bugs but I'm hoping it helps comic art collectors. It works with over 40 original comic art websites like Albert Moy (Jim Lee's art dealer), Cadence Comic Art, Artcoholics, a bunch of Big Cartel sites like Jim Cheung / Jason Fabok / Dustin Nguyen, Greg Capullo Art, Skottie Young, and more. It's free to try @ https://ift.tt/zxsdNtS , and you can upgrade to a paid plan if you want text messages alerts or want to check sites every 10 minutes or 1 minute. From a technical standpoint, my tech stack is: - Ruby on Rails - Hosted on Heroku - Emails sent by Mailgun - Texts sent by Twilio - Images hosted on Cloudinary - Credit card charging handled by Stripe and the new, low-code Stripe Checkout The minimum viable product was built in about a week with minor bug fixes and new features added weekly. If you have any feedback, have art sites you wanted added, or questions, let me know! https://ift.tt/zxsdNtS June 24, 2022 at 05:10AM

Show HN: In-depth photographic look at all the golf courses I play https://ift.tt/hLCUM9V

Show HN: In-depth photographic look at all the golf courses I play I'm an avid golfer; it's my main hobby. I decided to start taking pictures of all the courses I play. While there's a lot of golf websites out there, none of them really try to document the courses in depth and look at each hole, along with the course facilities like the practice areas. I live in Chicago and am starting with the courses in this area (of which there are dozens of public courses to play). While I play golf, I take photos with my phone of every (relevant) aspect of the golf course I can think of. Then they're processed and organized on the website. Obviously I'm starting this journey on my own, and in that sense it's not scalable. I won't be able to visit all the courses in the US, let alone the world. I hope to find others that would like to contribute to the effort. At some point I'd like to add course news and histories to the site. Many golf courses in the US are over 100 years old and have rich histories. And of course many older courses exist in Europe. I also have started adding descriptions/commentary for each hole on courses. For example, see: https://ift.tt/YfFbNQv... And maybe went a little overboard on this one: https://ift.tt/HdVPcQs... Anyway, it's a fun project and could go in a lot of directions. PS: I'm always looking to expand my golfing circle. If you're in Chicago and want to play sometime, hit me up -- contact details are on the website. https://ift.tt/wTyF2mg June 24, 2022 at 02:53AM

Show HN: Pragmatic Formal Modeling (Tutorial series with runnable examples) https://ift.tt/F2dC1Xx

Show HN: Pragmatic Formal Modeling (Tutorial series with runnable examples) Formal modeling is a mathematical approach for designing and checking correctness of software systems. It focuses on standard software engineering and distributed systems problems of the sort programmers face every day. It takes a pragmatic engineering approach: each problem starts with UML diagrams, design decisions and sometimes even a requirements document. We work through how to get from a whiteboard design to an initial mathematical model. Then we refine it based on logical errors found by the model checker, which return with a level of detail unheard of in a standard debugger. Formal modeling is a skill every engineer should have in their toolbox. All the examples are downloadable, and their is a quick setup section at the start. Additionally, there is an explorable model error debugger build right into the website. https://ift.tt/pH7nkXY June 23, 2022 at 12:43AM

Show HN: Crocodile - Better code review for GitHub https://ift.tt/3O5KBJY

Show HN: Crocodile - Better code review for GitHub Hi HN! I've been working on a code review app for GitHub called Crocodile for about a year. I used to work at Microsoft where we used a tool called CodeFlow for reviewing code and I missed it after I left. I know many other ex-Microsoft engineers feel the same. Here are some of the distinguishing features of Crocodile that are inspired by CodeFlow: * Comments float above the code instead of being inline. Long discussions that are displayed inline make it really hard to review the code. * Comment on any text selection in the file, even a single character. * Comments don't get lost when code changes. I hate it when comments become "outdated" because I rebase or the line is edited. I also implemented lots of features that I wish CodeFlow had which you can read more about on the blog. [1] For those curious about the tech stack: it's mostly written in Go with Alpine.js, HTMX, and Tailwind CSS for the frontend. For storage I use PostgreSQL, S3 compatible object storage, and Redis for caching. I use Pulumi for infrastructure provisioning and Kubernetes deployments. Everything is hosted on DigitalOcean. Feedback is welcome! [1] https://ift.tt/8QNMKoT https://ift.tt/1NRTszh June 23, 2022 at 03:07AM

Show HN: Diary of building software startup from scratch https://ift.tt/8hDSQ6N

Show HN: Diary of building software startup from scratch Oh, hello. I didn't see you there. Did you ever wonder what it takes to build and launch a software product from scratch? Not a high-level summary. Not a short essay that describes a year of development. Detailed, day to day activities. A captain's log. Mistakes and pivots. Technology choices. Marketing activities. Design considerations. You might know me as the creator of SumatraPDF. I'm starting a new software product from scratch and I decided to make it an experiment of building in public. I hope to inspire others to build more software by de-mystifying the process of creation. I'm on day 14. It's early but that is the point: you can follow along. Here's the daily dev diary: https://ift.tt/e9WBpT5 The product is Filerion, a web-based file browser / file manager with support for s3, Dropbox etc. I'll be posting updates to https://twitter.com/kjk but don't just follow along. Start building your own stuff as well. The world needs more great software. June 22, 2022 at 11:53PM

Show HN: Data Diff – compare tables of any size across databases https://ift.tt/kpquCmE

Show HN: Data Diff – compare tables of any size across databases Gleb, Alex, Erez and Simon here – we are building an open-source tool for comparing data within and across databases at any scale. The repo is at https://ift.tt/oedJAwE, and our home page is https://datafold.com/. As a company, Datafold builds tools for data engineers to automate the most tedious and error-prone tasks falling through the cracks of the modern data stack, such as data testing and lineage. We launched two years ago with a tool for regression-testing changes to ETL code https://ift.tt/rmDn5GM. It compares the produced data before and after the code change and shows the impact on values, aggregate metrics, and downstream data applications. While working with many customers on improving their data engineering experience, we kept hearing that they needed to diff their data across databases to validate data replication between systems. There were 3 main use cases for such replication: (1) To perform analytics on transactional data in an OLAP engine (e.g. PostgreSQL > Snowflake) (2) To migrate between transactional stores (e.g. MySQL > PostgreSQL) (3) To leverage data in a specialized engine (e.g. PostgreSQL > ElasticSearch). Despite multiple vendors (e.g., Fivetran, Stitch) and open-source products (Airbyte, Debezium) solving data replication, there was no tooling for validating the correctness of such replication. When we researched how teams were going about this, we found that most have been either: Running manual checks: e.g., starting with COUNT(*) and then digging into the discrepancies, which often took hours to pinpoint the inconsistencies. Using distributed MPP engines such as Spark or Trino to download the complete datasets from both databases and then comparing them in memory – an expensive process requiring complex infrastructure. Our users wanted a tool that could: (1) Compare datasets quickly (seconds/minutes) at a large (millions/billions of rows) scale across different databases (2) Have minimal network IO and database workload overhead. (3) Provide straightforward output: basic stats and what rows are different. (4) Be embedded into a data orchestrator such as Airflow to run right after the replication process. So we built Data Diff as an open-source package available through pip. Data Diff can be run in a CLI or wrapped into any data orchestrator such as Airflow, Dagster, etc. To solve for speed at scale with minimal overhead, Data Diff relies on checksumming the data in both databases and uses binary search to identify diverging records. That way, it can compare arbitrarily large datasets in logarithmic time and IO – only transferring a tiny fraction of the data over the network. For example, it can diff tables with 25M rows in ~10s and 1B+ rows in ~5m across two physically separate PostgreSQL databases while running on a typical laptop. We've launched this tool under the MIT license so that any developer can use it, and to encourage contributions of other database connectors. We didn't want to charge engineers for such a fundamental use case. We make money by charging a license fee for advanced solutions such as column-level data lineage, CI workflow automation, and ML-powered alerts. June 22, 2022 at 10:28PM

Show HN: Effortless Authentication for Your Web Application Hey folks, Michael here. I have been working in this project on and of for about a year and a half and I finally got it into a state where I can share it. I initially started this project to learn Rust and afterwards decided to make it useful for others. Vulpo Auth is an authentication server that you can host yourself. The goal was to make it as easy as possible for you to get started and have a complete authentication solution without you having to configure anything. Project Website: https://auth.vulpo.dev The Project contains: - Auth Server (Rust) - Admin Dashboard - JS and react SDK - Prebuilt Web UI (currently react) (https://ift.tt/PQZXdk3) - rust SDK for rocket Some of the features: - Email and Password Auth - Passwordless Auth - Google Auth - Translateable Email Templates - Enable/Disable Sign In or Sign Up - Password Reset Flow - Update Email Flow There is still a lot to do, the code base is full of experimental ideas and there a bunch of things to clean up, but first I want to focus on writing documentation and guides before adding more features. Besides the missing documentation, what are you missing? June 20, 2022 at 12:08AM

Show HN: Remove Silence from Videos with Ffmpeg https://ift.tt/TJtyExh

Show HN: Remove Silence from Videos with Ffmpeg There was recently a Show HN for a program that lets one remove silence from video files [0]. I was almost certain that ffmpeg could do this... But after searching for it, it turned out I was wrong: ffmpeg can't do this out of the box, and also can't read input from an EDL file [1]. So I set out to write a solution, as simple as possible: produce a list of select filters that are applied to video and audio, and retain only the non-silent parts. The 'silencedetect' audio filter detects silences, and produces timestamps for when silences start and end. So one can pipe the output of that to a Python script, that builds an ffmpeg command with the appropriate select filters. The resulting ffmpeg command can be run to re-encode the video without the silent parts. Hope this helps. - - - Notes: 1/ I did find something somewhat similar to what I ended up doing [2], but it's complicated, and does the video encoding inside of Python. Granted, moviepy uses ffmpeg under the hood, but it's still better if ffmpeg does all the encoding directly. 2/ This solution doesn't produce a myriad of intermediary files that it would recombine afterwards; there is just one encoding of the output video file. 'silencedetect' is very fast, so all in all running this should be pretty fast.

Show HN: QuickOWL – Quickly open favourite URLs with selected text as input QuickOWL (https://quickowl.app) is a custom contextmenu extension/add-on, for browsers & Thunderbird Email client, to quickly open user defined web links (URLs) with selected text from a browser/email as input. Inspiration: The inspiration behind developing this extension was: work related bugs or tickets which come in plain text format in emails or internal work portal reports. In order to open the bugs/tickets which are plain text, the usual steps followed are: 1) copy the bug/ticket number 2) open the respective internal bugs/tickets portal 3) paste the copied bug/ticket number and hit a button to do the search or to open it directly Above scenario is only for bugs/tickets, if our work or day-to-day life demands such copying and pasting of text across websites we will be wasting significant amount of time on this process. The QuickOWL extension/add-on aims to remove the steps 1 & 2, and directly sends the selected text (bug/ticket number) to respective bug/tickets portal as input. June 16, 2022 at 10:14PM

Show HN: Cut your AWS costs by stopping non-production resources when not needed https://ift.tt/WH9QJ0t

Show HN: Cut your AWS costs by stopping non-production resources when not needed Hello HN community! Sri and Brian here from CloudPal (https://ift.tt/JAxs3UW). We are building a tool to help companies reduce their cloud costs by stopping non-production resources when they’re not needed. The problem: Almost every company on the cloud struggles with cost management. While optimizing production costs can be complex, reducing non-production costs should be a straightforward case of shutting down resources when they’re not in use. However, most companies lack an elegant solution for this. The solution: CloudPal - A downtime scheduler for non-production resources (currently supports AWS EC2 & RDS) - start / stop button, allowing users to override the schedule (eg. if working on weekends). Next up on the feature roadmap is: - Intelligent start / stop functionality for non-production resources - resources will automatically stop when not in use and quickly spin back up when needed, resulting in lots more delicious cost savings! - Support for more cloud providers and resource types (eg. ECS, K8s, etc.) We're really happy we get to show this to you all, thank you for reading about it! Please let us know your thoughts and questions in the comments. Many thanks, Sri & Brian June 15, 2022 at 11:58PM

Show HN: FlexMeasures ― optimize flexible energy demand, in Python https://ift.tt/ganf6qb

Show HN: FlexMeasures ― optimize flexible energy demand, in Python Hi, this is for everybody who is interested in clean tech, especially real-time automation within new energy systems. We've been working on FlexMeasures for a while ― an energy management system (EMS) with a focus on using demand flexibility to its maximum potential. We're running it in several pilots ourselves, but our aim is to speed up the energy transition across the world. Let's not re-invent the wheel (i.e. a software stack around time series and optimization) too many times. Wherever you are in the world, and whatever setting you might be looking at (energy-modern housing in the U.S., smart e-mobility in Africa, self-balancing microgrids in Indonesia, etc.), maybe some of you will like our approach. We've decided that making it easy and clear for developers to build such energy solutions can bring the largest gains. The first step towards that goal was a permissive license (Apache 2.0). The latest step we took was a Docker image (we got a Docker-based tutorial here: https://ift.tt/9D8EIlY... ). You can see the code at https://ift.tt/STp12EG Since recently, FlexMeasures is a project within the Linux Energy Foundation ( https://ift.tt/T42kin6 ), which helps to establish a proper governance and quality standard. Actually, upcoming Thursday is our next Technical Steering Committee meeting, and interested people are warmly invited: Thursday, June 16 at 8:00 am US Pacific Time / 11:00 am US Eastern time / 5:00 pm Central European Time https://ift.tt/m93wyzJ We'd love to hear from you! https://ift.tt/eki9Uya June 13, 2022 at 10:32PM

Show HN: Visualizing the math that powers 3D character animation https://ift.tt/DJku8Oq

Show HN: Visualizing the math that powers 3D character animation Hi everyone! I'm the author of this project. I wrote it because I think that the math that makes characters move in games and movies is incredibly beautiful, and I wanted to give others a glimpse into it. It's crazy to think that quaternions, an abstract mathematical tool discovered by William Rowan Hamilton in 1843, would be so perfectly suited to solve hard problems in the world of 3D character animation more than a hundred years later. The story of how he discovered quaternions is also beautiful. Here's an excerpt from Wikipedia: "Hamilton was looking for ways of extending complex numbers (which can be viewed as points on a 2-dimensional Argand diagram) to higher spatial dimensions. In working with four dimensions, rather than three, he created quaternion algebra. According to Hamilton, on 16 October he was out walking along the Royal Canal in Dublin with his wife when the solution in the form of the equation i2 = j2 = k2 = ijk = −1 occurred to him; Hamilton then carved this equation using his penknife into the side of the nearby Broom Bridge (which Hamilton called Brougham Bridge)." There's a plaque that commemorates that moment on Broom Bridge now. If you have any questions about this project, I would love to answer them, but I recommend reading the README first, which should explain everything: https://ift.tt/hIkbasH...

In-Person Pride Parade & Celebrations Return This Month!

In-Person Pride Parade & Celebrations Return This Month!
By Pamela Johnson

The SFMTA is happy to join San Francisco Pride celebrations when they return to in-person events this month as the city continues its recovery from the pandemic. This year’s theme is “Love will Keep Us Together.” The Trans March is happening on Friday, June 24 and the Pride Parade is on Sunday, June 26. SFMTA staff are, of course, an important part of the LGBTQIA+ community that keeps SF moving with Pride. Pride is an opportunity for us to demonstrate our continued support of the LGBTQIA+ community, promoting our core values of respect, inclusivity and integrity. 

History/Background of SF Pride  

San Francisco had its first Pride celebration in 1970. For more than three decades the LGBTQIA+ community and their allies have been moving San Francisco forward to become a better, safer, and more equitable world for the LGBTQIA+ community and the city a better place for people to live, work and enjoy.   

Historically, San Francisco's Pride parade is the largest in the country with more than a million people in attendance, usually including travelers from cities across the country and around the globe celebrating and paying homage to the members of the LGBTQ+ community.  

Diversity, Equity & Inclusion for All 

Pride is a celebration and counterpoint to the discrimination and challenges the LGBTQIA+ community has historically faced. And we can all be proud that San Francisco has been a pioneer on such issues as same-sex marriage, health care and anti-hate legislation. 

Recognizing the strides and achievements made by the LGBTQIA+ community over more than five decades, the SFMTA’s theme for 2022 is "Moving San Francisco with Pride.” As home to one of the world's largest and most prominent LGBTQIA+ communities, we look forward to celebrating Pride all month long.

Improving Safety on 16th Street

Improving Safety on 16th Street
By John Gravener

Construction on Phase 2 of the 16th Street Improvement Project began May 9, 2022. 16th Street is part of the city’s High Injury Network, where 75% of the city’s severe and fatal traffic incidents occur on just 12% of the city’s streets. This project, in addition to improving reliability of the 22 Fillmore line, has several pedestrian safety features that will make 16th Street a safer place for all modes of transportation.

For people who walk on 16th Street:

One of these safety elements is the installation of 2 new pedestrian bulbs at Guerrero Street and South Van Ness Avenue. These bulbs shorten the crossing distance between the corners of an intersection and make people who are about to cross the street more visible to drivers. The bulbs also require vehicles to slow down when making right-hand turns. High-visibility crosswalks will be installed. These make it easier for people driving to see people crossing the street, and also aids people with low-vision in crossing the street safely

New traffic signals with pedestrian countdown signals will let people walking know how much time they have to cross the street before the traffic light changes. In response to community concerns about pedestrian safety, a new accessible pedestrian signal with pedestrian countdown and audible tones will be installed at Shotwell Street, a designated Safe Street.

For people who ride transit on 16th Street:

In some areas along the corridor, sidewalks at bus bulb-out locations will also be widened as part of the project. Wider sidewalks act as a buffer between traffic and people on sidewalks and make it safer for people riding transit to board and alight from buses. Buses remain in their dedicated transit lane, while people can step directly between the bus and the curb safely. This also improves transit efficiency as buses do not need to pull back out into their lane to continue their route.

For people biking near 16th Street:

During Phase I of the project, the SFMTA extended the bicycle route on 17th Street. This allows for a safe and attractive east-west connection for people on bicycles. As a part of the bicycle network, the bicycle route improves conditions for people on bicycles and enhances connections to the existing bicycle network. This network allows people to travel from the Castro to Mission Bay safely by bicycle.

Public safety is important, and all SFMTA construction projects include that in the planning and design process. The 16th Street Improvement Project wants to make sure that pedestrians, transit riders and bicyclists arrive safely at their destinations.

Show HN: TLDR (short) news website with my own algorithm I'm actively working on a news shortening website. Trying to save you from clickbaits, save your time and save you from reading Bible-sized articles What I hate the most when reading news is reading Bible-size articles just to find the main point of the article. Usually journalists write a bunch of unnecessary information just to create 400+ long articles and position better on Google. Worst of all are those clickbait titles or titles that tell you a portion of information just to make you intrigue and make you click on the article. For me personally, it is very annoying and frustrating. I like to spend like 30 seconds tops on an article, I want to get the information as fast as possible and move on. So with my [ExcerptDaily]( https://ift.tt/vc8oENU ) I'm trying to: * Save people's time * Inform you as fast as possible * Give you the main point of an article in 5 sentences * Save you from clickbait or half clickbait titles I wrote my own algorithm and tried a few of them, now I'm focusing on my own algorithm and making it better.

Muni Metro Fix It! Week Improves Rail Service, Safety and Reliability

Muni Metro Fix It! Week Improves Rail Service, Safety and Reliability
By Jessie Liang

Overhead Line Department replacing wire and custodians cleaning metro station during Fix It! Week, April 19, 2022

A new quarterly effort to increase work time to accomplish necessary Muni Metro system maintenance in April 2022 was a resounding success. Here is a behind-the-scenes video recap. The maintenance initiatives aimed at making subway operations more reliable and preventing feature breakdowns. The maintenance teams were able to perform an entire month of work within the 10 days when subway service was substituted by bus service to provide SFMTA workers the extended Fix It! Week work window. 

Every night after Muni Metro subway service hours, SFMTA maintenance crews work to maintain the tracks and equipment underground. On most nights, this gives our teams only about two hours to get work done. During the first Fix It! Week, from April 14 to April 23, 2022, buses provided substitute service for Muni Metros lines and the subway between Embarcadero and West Portal was closed early for work to begin at 9:30 pm. These nightly early shutdowns gives SFMTA maintenance crews more hours to complete infrastructure improvement works underground that cannot be completed during the normal windows. 

The Fix It! Week provided 56 total work hours, during which several SFMTA teams completed over 2,000 hours of maintenance and inspections. On the busiest nights, the maintenance teams had up to 55 staff in the tunnel from West Portal to Embarcadero delivering safety improvements, station and tunnel enhancements, subway track and wayside equipment maintenance, and traction power upgrades.  

Each night during Fix It! Week, custodians from the Buildings and Grounds teams did deep cleaning at West Portal, Forest Hill, Castro, and Church stations, while the Maintenance Engineering staff was in the tunnel inspecting and collecting data. Stationary engineers from Mechanical Systems in various stations focused on safety enhancements such as installing new safety handrails at the platform ends, new ventilation for station agent booths, new pump covers, fire and life safety systems, and new electrical room ventilation.  

The Overhead Lines crew also used Fix It! Week to replaced 600 feet of wire at Castro Station while the Track Maintenance team brought two pieces of 1,500-pound stock rail in and out of the subway. The Motive Power crew replaced emergency battery systems and worked with all-electrical clearance holders to restore systems on time for rail service to restart as the Signal team removed legacy train control systems for future upgrades. The Underground team and the Paint Shop staff also contributed to this remarkable accomplishments. The Cable Car division, who had not previously participated in extended maintenance periods, did channel and conduit cleaning and checked and confirmed all wires were in good condition during the April Fix It! Week. 

Many people in the support team who were not doing the maintenance but coordinating the efforts all helped to make Fix It! Week successful. They ensured safety standards were being upheld, critical repair priorities were being addressed, and the subway was being reopened to restart rail service on time every day. 

Muni operations and transportation infrastructure are vital to San Francisco’s economic vitality, environmental sustainability, and cultural diversity. The FY 23 - FY 24 SFMTA Budget will continue to invest in infrastructure improvements to keep the Muni Metro system in a state of good repair. Thank you for your patience and understanding while we improve the safety, reliability and on-time performance of the Muni Metro system. 

The next Fix It! Week will be happening in August of 2022.

Show HN: WunderGraph – open-source API Developer Toolkit https://ift.tt/BkdRKwP

Show HN: WunderGraph – open-source API Developer Toolkit Dear HN Community. We're Bjorn, Dustin, Stefan & Jens, the founders of WunderGraph. More than two years ago, Jens started WunderGraph as a Side Project. The initial idea was to solve the problem of integrating multiple disparate DataSources into a single, unified API Layer. While solving this problem, Jens realized that his mental model of APIs was wrong. Most API tools treat APIs as abstract things or just endpoints, in a very imperative way. At some point, he realized that there's a better model to think about APIs: APIs are dependencies and we should treat them in a declarative way! And that's how the idea of the "Package Manager for APIs"[1] came to be: WunderGraph is an API Developer toolkit which allows you to import and export APIs, just like npm packages. This is possible because every WunderGraph project generates a static, conflict-free and versionable artifact. It shouldn't take days to add a new 3rd party API to your API layer, with WunderGraph, this is possible in seconds. WunderGraph lets you define your API dependencies in a declarative way. The whole "Graph" of API dependencies is represented as an unified GraphQL Schema. Meta-data like API credentials, can be configured with our TypeScript SDK. API Operations are defined as regular GraphQL Operations. Custom middleware / business logic can be written using TypeScript. Finally, WunderGraph generates a Gateway + Client(s). Gateway and clients communicate via JSON-RPC. We call this approach "Compile-time" GraphQL queries. The client is 100% TypeSafe. The Gateway handles Authentication, Authorization, Caching, Middleware, etc... WunderGraph gives you the Developer Experience of working with a single, monolithic API layer, although you're using many different internal and external Services and Databases behind the scenes. WunderGraph Supports any OpenID Connect compliant IDP for Authentication, S3 for file storage, REST (OpenAPI), GraphQL & Apollo Federation for APIs and PostgreSQL, MySQL, SQLite, SQLServer, Planetscale and MongoDB for the data-layer. Today, we're happy to announce that WunderGraph is finally Open Source! Check out the Monorepo[2] on GitHub. If you like our ambitions, give us a star! You can run WunderGraph locally and air-gapped, no strings attached. There's also a more extensive release post on our blog[3]. Have a look at the examples[4], we're keen to hear your opinion!

Show HN: Lorblets, a Little Puzzle Game https://ift.tt/D98C3AY

Show HN: Lorblets, a Little Puzzle Game Lorblets is a little puzzle game I made: https://ift.tt/CTyAiWu Lorblets is a variation on Lights Out. The goal of Lorblets is to turn ON all the lights. Unlike Lights Out (typically a grid of black and white squares), Lorblets puzzles have complex shapes (and bright colors!). The puzzles in Lorblets are generated at random from a seed, and they grow in size as you progress. The code quality is...not great? The design leaves something to be desired. And the game itself is a bit derivative. So why am I sharing this? Because I want to celebrate having shipped a complete game - modest though it may be. I'm a 39yo who has long dreamt of one day making a game. And yet I've tended to put my software engineering skills to work doing everything except that. I've devised complicated game mechanics on paper. I've written multiple overly complicated game "engines" in JavaScript. I've daydreamed for countless hours about my magnum opus: a 3D simulated open world with a natural language interface, narrative generation, character customization, scene building tools, a modding system... Long story short, that magnum opus has been fun to tinker on, but has not amounted to much beyond the spinning of wheels and the occupation of my free time. So over the Memorial Day holiday I decided to force myself to complete one game before the weekend was over. I would conceive the simplest possible game mechanic and UI. I would not worry if it was unoriginal. I would resist the urge to add complexity. I would not get bogged down standing up a framework. I would not build an "engine." I would not worry about clean code, or maintainability, or even performance. I would use the tech stack that I could work fastest in: web tech. And I would not worry that the astral projection of Jonathan Blow would visit me at night and chide me for having made a badly performing web browser game. So, Lorblets is the result. Whatever one might say about it, it IS a game, and that's something. Feedback is welcome of course - but I mostly just wanted to share my story with y'all. June 4, 2022 at 10:43PM

Show HN: Cryptid Zero Trust Authentication and Authorization, Open Source Oberon Oberon makes it possible for a service provider to issue capability tokens to clients in such a way that the service provider never sees the value of the capability token. This prevents the service provider from being able to impersonate the client. Oberon relies upon zero-knowledge proof presentation of the capability token so that the token is never transmitted norrevealed. Instead of the client sending the token to the service—as is done with API tokens today—the client sends a zero-knowledge proof proving that they have a valid capability token issued by the service provider; this is called proof-of-knowledge.

Muni Adding More Service July 9

Muni Adding More Service July 9
By Mariana Maguire

The 6 Haight/Parnassus was temporarily suspended in March 2020 and will be brought back into service July 9, 2022, along with the 2 Sutter and 21 Hayes. 

As the SFMTA prioritizes service equity and responds to changing travel patterns, we are planning to bring back additional routes that have been temporarily suspended since March 2020: The 2 Sutter (formerly 2 Clement), 6 Haight/Parnassus and 21 Hayes. The 6 Haight/Parnassus will return to its full pre-pandemic route, while the 2 Sutter and 21 Hayes will return in response to community feedback with changes to make the most of limited resources. System improvements like transit-only lanes and subway upgrades have helped us make transit service more reliable overall as we keep restoring routes.  

These changes are part of the 2022 Muni Service Network plan. Read more about what we heard from the public and how we incorporated feedback into the 2022 service proposal.  

The 2 Sutter will run between Ferry Plaza on Steuart Street near Embarcadero and Presidio Avenue and California Street, restoring connections to the Jewish Community Center food hub – a priority for many seniors we heard from. Customers who want to reach Clement Street (one block south of California Street) will be able to transfer to the 1 California at California Street and Presidio Avenue to continue west. 

The 21 Hayes will run between Fulton and Shrader streets near St. Mary’s Hospital to Hyde and Grove streets, by Civic Center Station and the Main Library, restoring connections to the hospital. Customers who want to continue along Market Street can transfer to any eastbound Muni Metro subway route, the F Market surface rail, or one of the bus routes serving Market Street including the 6 Haight/Parnassus and 7 Haight/Noriega. 

We will publish comprehensive service change details including maps later this month. 

Route Modifications 

We plan to make modifications to several existing routes to restore access and connections that community members have requested. These modifications improve or restore connections to food hubs and hospitals for people with disabilities and seniors and access to jobs for Service Equity neighborhoods 

• The 23 Monterey will be extended to its pre-pandemic route along Sloat Boulevard. 

• The 28 19th Avenue will be extended to Powell and Beach streets to provide east-west connections to Fisherman’s Wharf across the northern part of the city. 

• The 43 Masonic will be extended to its pre-pandemic route to serve the Presidio, Marina and Fort Mason. 

• The 52 Excelsior will return to its pre-pandemic route. 

• The 57 Parkmerced will be extended to West Portal. 

• The 58 Lake Merced will return to Lake Merced Boulevard and Brotherhood Way. 

• The 66 Quintara will return to its pre-pandemic route. 

In addition to these changes, the L Bus will be shortened and increase frequency between the San Francisco  Zoo and West Portal Station in response to changing trip patterns and subway improvements. With more subway reliability after extensive repairs and maintenance, many L Bus riders are choosing to transfer to the subway at West Portal for a faster ride to downtown. This allows us to shorten the L Bus route while increasing frequency and putting limited resources on other routes that are experiencing crowding. 

Looking Ahead 

We plan to continue implementing the approved 2022 Muni Service Network in additional phases as we bring more transit operators onboard. Read more about the complete 2022 Muni Service Network plan.

Muni Forward Gets San Francisco Moving

Muni Forward Gets San Francisco Moving
By Shalon Rogers

The SFMTA’s Muni Forward program is delivering transit reliability improvements that are transforming the Muni system and enhancing the customer experience. With 80 miles of upgrades since 2014 that often bring travel time savings of 20% or more, Muni Forward is making a big difference in how San Francisco moves. These upgrades, which can be seen in this Muni Forward Photo Map, draw from a “toolkit” of over 20 reliability and customer experience improvements, such as transit lanes that provided dedicated space for Muni vehicles to cut through traffic, transit bulbs that reduce delays at transit stops and traffic signals with transit priority that give the green light to transit vehicles as they approach the intersection, when possible.

The recently completed Van Ness Improvement Project thrust Muni Forward back into the spotlight with San Francisco’s first Bus Rapid Transit (BRT) corridor. While the Van Ness Improvement Project was a massive overhaul that required significantly more time and money to implement than the average Muni Forward project, we are seeing familiar benefits resulting from the transportation improvements. In just under two months, Muni riders on Van Ness are seeing a travel time savings of up to 35% northbound (up to nine minutes per trip) and 22% southbound on weekdays. After the first week of this drastically improved service, ridership on the 49 Van Ness-Mission increased by 13%.  

We’ve seen similar outcomes on past Muni Forward projects that share many features implemented on the BRT corridor. In addition to improved travel times and reliability, ridership has increased by 10% or more on many of the lines where Muni Forward improvements have been implemented, such as the 5R Fulton Rapid, 9R San Bruno Rapid and 38R Geary Rapid. And though ridership has decreased during the pandemic, it has returned fastest on many of the lines where we’ve made these improvements, such as the 22 Fillmore, which now has more riders than in 2019. 

New transit bulb on Irving Street

Thanks to Muni Forward, San Francisco now has over 60 miles of dedicated transit lanes. Among these are the lanes that were installed as part of the Temporary Emergency Transit Lanes program. Made permanent in late 2021 and early 2022, these lanes have provided travel time savings of up to 31% for routes that carry 40% of current Muni customers, including the T Third, 1 California, 14 Mission, 14R Mission Rapid, 19 Polk, 27 Bryant, 28 19th Avenue, 38 Geary, 38R Geary Rapid, 43 Masonic and 44 O’Shaughnessy. 

New carpool lanes on Park Presidio Boulevard

Another notable recent Muni Forward project is the Park Presidio Lombard Temporary High-occupancy vehicle (HOV) lanes, which are the first urban arterial carpool lanes in the state. In partnership with Caltrans, this pilot project is already seeing travel time savings of up to 10%. 

Looking ahead, Muni Forward is not slowing down. Planning is underway for improvements on the 29 Sunset, and we’ve started construction on improvements to the 22 Fillmore, 28 19th Avenue and L Taraval. We’re also preparing for construction on improvements to the 14 Mission, 5 Fulton, 27 Bryant and 30 Stockton. Plans for transit delay hot spot improvements are also in the works, which will help improve Muni reliability at specific intersections where we have seen the most transit delay for Muni.  

Additionally, making improvements to Muni’s Metro service will be a major focus over the next few years. Upcoming Muni Forward projects will focus on surface-level improvements for the J Church, K Ingleside, M Ocean View, T Third and N Judah, which will complement the Muni Metro Modernization efforts that are already underway.

Emergency Response Transit Lanes Program Shows Long-term Success

Emergency Response Transit Lanes Program Shows Long-term Success
By Erin McMillan

After the Temporary Emergency Transit Lane program used a quick-build approach to install over 15 miles of emergency-response transit lanes in about 18 months, we have the numbers that show its success. Here is the program evaluation summary. 

During the early months of the pandemic, with traffic at an all-time low, Muni routes saw a 15% reduction in travel time on average and as much as 50% on certain corridors. Building off this analysis, the SFMTA identified key routes that could benefit from transit lanes that would preserve those speed and reliability improvements. These transit lanes improved reliability along the entire line, improving rider experience in Muni Service Equity Strategy neighborhoods and throughout the city. This allowed us to provide more frequent and less crowded service at a time when resources were very limited.

We launched the Temporary Emergency Transit Lane (TETL) program to preserve this time savings even as traffic returned, so people making essential trips on Muni wouldn’t get stuck on slow and crowded buses. The program also helped us provide as much frequency as possible despite pandemic-related limitations on operational resources, and build up Muni’s resiliency to ensure an equitable and sustainable economic recovery.

Overall, the TETL program saw the following measurable benefits:

• Travel times savings of up to 31%.
• Improved reliability on lines serving 40% of all Muni riders.
• Up to 89% of surveyed operators stated that the improvements made their jobs easier.

The TETL program helped make the last two years the fastest expansion of transit lanes in the city’s history, benefitting riders on the 1 California, 14 Mission/14R Mission Rapid, 19 Polk, 27 Bryant, 28 19th Avenue, 38 Geary/38R Geary Rapid, 43 Masonic/44 O’Shaughnessy and T Third. Moreover, all these projects benefit lines that serve neighborhoods identified by the Muni Service Equity Strategy.

With these great results early in the program’s implementation, six of the seven TETL corridors were made permanent in late 2021 and early 2022 after extensive evaluation and outreach. One corridor, the Park Presidio Lombard Temporary HOV Lanes, will continue as a longer pilot to allow for further evaluation in partnership with Caltrans.

The TETL program was a critical piece of the SFMTA’s response to the COVID-19 pandemic. Moving forward, the initial shelter-in-place travel time savings analysis used to identify corridors for TETL improvements will be used to identify additional corridors for future improvements as part of Muni Forward, the SFMTA’s ongoing transit priority program.

Show HN: A color palette design tool for websites https://ift.tt/zFKrEJA

Show HN: A color palette design tool for websites Hi HN, while building something entirely, I realized that there is a lack of tools to pick colors for websites and web apps. While there certainly is an abundance of tools for color palettes, but they mostly give you three to five bright or pastel colors. Not what you need for websites. For that, you need one or two primary colors, and then stuff like text color, background, and so on. So, together with another web dev I built a small web tool that allows picking exactly the colors you need for web projects and live preview your palette on a selection of demo websites. The first version of the tool is online at https://ift.tt/lVIBdhE. Free and no sign up. We are already using this to for early stage projects, so I hope this provides value for you as well. Of course we are also happy about any and all feedback. Cheerz :) June 2, 2022 at 01:08AM

Show HN: Equals – a spreadsheet that you can write SQL in https://ift.tt/UWktfRv

Show HN: Equals – a spreadsheet that you can write SQL in Hey Hacker News, Today we're launching Equals. Equals is a spreadsheet with native connections to your SQL databases and data warehouses. You can write SQL right in your spreadsheet. Equals was born out of a shared frustration of me and my co-founder. Despite the avalanche of new data tools over the last decade – nothing actually seemed better than a spreadsheet. Nothing was as flexible, malleable, and as easy to just dive in and play around with some data. In fact, you nearly always ended back in a spreadsheet regardless of what fancy set up you had: when something broke, when a chart in a BI tool didn't quite make sense, etc. You can learn more about Equals here: https://equals.app/ We'd love to hear what you all think.
