<About Me />

我是 CoolArec，一名计算机专业学生，也曾是 ACM/ICPC 竞赛选手。大学几年里，我的大部分时间被训练赛、补题、课程设计、社团维护和各种临时任务填满：从 501 到 504 再到 409，从第一次省赛银牌到区域赛退役，我在很多个深夜里对着代码、报告和服务器发呆，也慢慢学会从题目和项目里寻找一点真正属于自己的东西。我喜欢折腾网站、服务器和各种能跑起来的小项目，也做过编译器、题目管理系统、单片机播放器这类有点奇怪但很有成就感的东西。算法竞赛让我习惯在混乱里找结构，项目开发则让我相信，只要一点点把接口、部署和 Bug 理顺，很多想法最终都能落到能运行的地方。我把这个博客当作一份持续生长的备忘录，用来保存比赛时封榜前后的心跳、路上的风、学校里的猫、动画和电影带来的精神支点，以及偶尔出现的自由感。很多时候我也没法确信自己要走向哪里，只能先把这些具体的瞬间写下来，然后继续往前走。
