《上古卷轴：天际》中 Keymaster 技能在数学上是无用的
作者逆向工程了《上古卷轴》天际（Skyrim）中扒窃成功率的计算公式，发现其中一个名为“Keymaster”的扒窃技能加成（描述为“偷钥匙几乎必定成功”）在实际数学上没有任何用处。 这是少数玩家群体里对游戏底层机制做认真剖析的内容，有信息增量（公式+结论），也容易在老玩家、游戏 mod 圈里引发讨论。

收藏《上古卷轴5》NPC 技能升级是如何运作的
作者在做 Skyrim 偷窃系统逆向时顺带挖出 NPC 技能成长机制，发现官方 wiki 的公式有误，并试图回答"谁拥有最低/最高的偷窃技能"。 属于游戏引擎逆向、社区知识纠错类内容，对 Skyrim modding、游戏机制爱好者有明确信息增量，能引发"wiki 还能信吗"类讨论，但受众偏垂直（RPG mod/逆向圈），大众传播力有限。
拆解《上古卷轴5》的偷窃系统
作者被朋友重新拉回《上古卷轴5》重玩，在游玩中觉得偷窃成功率数值不对劲，于是逆向工程了游戏底层机制。文章追述了Skyrim的窃取判定逻辑、相关数值表（如crime flag、actor level、技能权重等），并指出在特定条件下玩家可偷走远超正常上限的金币而不触发惩罚。 属于个人踩坑驱动的一手逆向分析，对喜欢游戏机制与数值工程的读者有较强吸引力，讨论点集中在"游戏数值到底怎么算"以及"能否合法白嫖金币"上。
重回“Ride the Bus”：补上中位数并找到获胜概率的闭式解
作者回顾自己大学时期关于经典“Ride the Bus”纸牌游戏的一篇概率分析，在重新查找原文时补上了之前遗漏的中位数结果，并顺手修复了早期模拟代码中的几处错误。 更关键的是，作者推导出了该游戏获胜概率的闭式解（closed form）。这是一篇数学爱好者向的个人博客更新，信息增量在于“闭式解”这一结论，适合对组合概率、随机过程或游戏数学感兴趣的读者。
