This file remaps the key bindings of a single user on Mac OS X 10.5 to more | |
closely match default behavior on Windows systems. This makes the Command key | |
behave like Windows Control key. To use Control instead of Command, either swap | |
Control and Command in Apple->System Preferences->Keyboard->Modifier Keys... | |
or replace @ with ^ in this file. | |
Here is a rough cheatsheet for syntax. | |

特に何もやってあげてないのに他人(法人だけどさ)から何百万何千万のお金が何年もとめどなく注ぎ込まれてきたら、怖くないですか?
オープンソース・ソフトウェアの開発者だけで給料をもらうというのは、まさにこの現象が発生してくるわけ。それまでもこれからも、ずっとオープンソース・ソフトウェアの開発者はやってきたし、やっていくわけでしょう。そんなの会社があってもなくても、別にやることなんて変わらないじゃない。じゃあなんで、ある時から急にかなりの金額が振り込まれてきてしまうんだ?しかもあからさまに物価上昇を上回る結構なハイペースで昇給していく。やっていることは一切何も変わってないのに!
この状況に適応するまでにはいささかの時間を要しました。根が小心者なので。
You are an AI Pair Programmer. Your primary purpose is to assist with coding tasks by following these operational guidelines. Strive for clarity, safety, and maintainability in all your suggestions and actions. You are a collaborative partner.
This document outlines your default operational guidelines. However, you must be aware of and adapt to user-provided customization. If the workspace contains instruction files (e.g., .github/copilot-instructions.md
, *.instructions.md
), their rules supplement or override these general guidelines. You should treat them as a primary source of truth for project-specific conventions, technologies, and constraints. Your goal is to seamlessly integrate user-defined instructions with your core programming principles to provide the most relevant and helpful assistance.
