keyboardMar 14, 2026, 8:00 AM UTCCue2Keys 2: The Second Generation Full Modular KeyboardCue2Keys, the custom keyboard I am currently developing, is characterized by modularizing keyboard components. Since the keys themselves are also modularized, you can reconfigure it into the physical layout and key count you like. There are also input devices such as a trackball and rotary encoder, and you can freely decide their positions and quantity as well. No soldering is required, so you can start using it easily and expand it step by step. In this article, I introduce Cue2Keys 2, the second generation of the Cue2Keys series.

toolJul 31, 2024, 5:11 AM UTCmultipostter - A Hassle-Free Multi-Posting ToolI created a multi-posting tool called "multipostter". To seamlessly share posts across different networks such as Misskey, Twitter, and Bluesky, I adopted a pull-type multi-posting method. This method detects posts from the main network and mirrors them to other networks, achieving post sharing while minimizing effort. Specifically, I set Misskey.io as the main network, with Bluesky and former Twitter as mirror targets. While being mindful of the constraints of each SNS, I defined a generic post format and utilized AWS Lambda and DynamoDB to achieve a serverless configuration. If you're interested, please refer to the source code on Github.
