Building a back end using only OpenAI Codex
13 by zegl | 1 comments on Hacker News. I've published the sources for the code generation and the code that was generated on GitHub: https://ift.tt/YJ8TS7x I've been experimenting with merging prompts together, with a goal to write the full backend in a single prompt. On the form: > 1. Setup a flask web server > 2. Add a /add endpoint It works reasonably well, but it seems like it's loosing some precision in the prompts... The person that coined the term "prompt engineering" was right, it's really important to learn what words to use to get the AI to do exactly what you want it to do.
Show HN: Exp. Smoothing is 32% more accurate and 100x faster than Neural-Prophet
49 by maxmc | 2 comments on Hacker News. We benchmarked on more than 55K series and show that ETS improves MAPE and sMAPE forecast accuracy by 32% and 19%, respectively, with 104x less computational time over NeuralProphet. We hope this exercise helps the forecast community avoid adopting yet another overpromising and unproven forecasting method.
Show HN: I created a browser automation tool
24 by iamandras | 7 comments on Hacker News. I created this tool a few months ago to automate some of my tasks. I use it to collect prices and files and to get notified when something changes on certain websites. The task runner uses Playwright. I'm not sure if it can be useful to anybody else besides me :) Any feedback is welcome.
Show HN: MutableAI (YC W22) – Copilot Alternative for VS Code
11 by oshams | 2 comments on Hacker News. Hi HN! We’re MutableAI (YC W22) ( https://mutable.ai ). Our mission is to reduce the time and cost to create high quality code using AI. We have worked at the full gamut of companies ranging from startups to big tech and have gotten the sense that many of the rote aspects of software development could be made easier, freeing up precious mental energy. Devs love Copilot, but autocomplete is just one of many ways that AI should make programming easier. We’re taking a more comprehensive approach to developer tooling that bundles Copilot-like autocomplete with documentation, custom AI instruction, and some early refactoring capabilities (Python only) in one extension. We currently support Javascript/Typescript, Python, Go, and Rust, with more coming soon. Overview (w/ bg music) [3]. In addition to autocomplete, which can be triggered either automatically or manually, we can add documentation to all your methods in a Rust file, or you can ask the AI to insert missing imports in a Python file. In some cases we can get really sophisticated and ask it to program a game from scratch or update your REST interface to accommodate a new data payload. We use a combination of AI (e.g. OpenAI codex) and AST transformation / metaprogramming techniques on the backend. We are also working on providing other backend solutions for varying needs, including on-prem deployments. We soft launched our product with a small cohort of users and want to welcome more of you to our pilot beta. We hope you enjoy the product and look forward to learning from you. We are currently in an extended free trial phase for early adopters and plan to keep a free tier for solo devs and open source contributors. We also offer a generous discount to startups. For enterprise please reach out to info@mutable.ai We want to thank our very earliest users and invite the HN community to try the product installing it via the VS Code marketplace [1]. We're looking forward to hearing your comments and feedback, or feature suggestions! [1] https://ift.tt/MxSc1Ff... [2] https://ift.tt/7s2mA8e [3] https://www.youtube.com/watch?v=x-gKEbgyzCg
