toolJul 31, 2024, 5:11 AMmultipostter - Effortless Multi-Posting ToolI created a multi-posting tool called "multipostter." To seamlessly share posts across different networks like Misskey, Twitter, and Bluesky, I adopted a pull-type multi-posting method. This approach detects posts from the primary network and mirrors them to other networks, reducing effort while enabling post sharing. Specifically, I set Misskey.io as the primary network and Bluesky and old Twitter as mirror targets. Considering the constraints of each SNS, I defined a universal posting format and utilized AWS Lambda and DynamoDB to achieve a serverless configuration. If you're interested, please refer to the source code on Github.

toolAug 14, 2020, 10:27 AMTrue Rent CalculatorI created a tool to calculate the true rent. When signing a rental agreement, various costs arise in addition to the stated rent. Typical examples include key money, and the actual rent can differ significantly from the apparent rent. Furthermore, there are many unclear costs such as insurance premiums and mysterious cleaning fees. This tool provides a function to display these costs in a unified and averaged rent. In this article, I will explain the background of the tool, how to use it, and the technical details using Rust's wasm_bindgen.
