Show HN: Calculator for US Individual Income tax, from 1970-present 60 by tmm1 | 18 comments on Hacker News. 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...

Show HN: Ploomber Cloud (YC W22) – run notebooks at scale without infrastructure 30 by idomi | 4 comments on Hacker News. 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/WzL6Gko ) 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...

Show HN: ColorTiles Browser Game 2 by Unit520 | 0 comments on Hacker News. 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! :)

Show HN: Inngest – an open-source event-driven queue 3 by tonyhb | 3 comments on Hacker News. 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/IeuUa5N and Dan was the CTO of https://buffer.com/. At both places, we had to buil...
