对AI编程能力的一点看法

————AI程序员离优秀还有距离

对AI编程能力的一点看法 AI根据提示词与历史文章风格参与创作记得几年前，确切地说是OpenAI那一波浪潮刚起的时候，山姆·奥特曼们就豪言壮语，说AI已经把人类迄今为止产生的所有知识都学完了。乍一听挺唬人，但仔细琢磨一下，实际情况远非如此。那些被喂给AI用于训练的数据或知识，本质上是AI开发者“能够得到”的知识。其中就算不是绝大多数，至少有很大一部分是来自互联网的公...

Vibe Coding的悖论以及AI的理解力

On a whim, I decided to try using the command-line interface of an AI for file-related operations, which is more convenient than web chat. I started with OpenAI’s Codex CLI, but it’s not...

Executing Tasks Exclusively

——确保任务顺序执行

优化项目中某项功能时我提出了一个需求，类似于访问WPF的界面控件需要在GUI线程上一样，我希望某些代码在后台线程执行，但同一时间只能干一件事，这样可以简化代码不需要显示使用锁。 ConcurrentExclusiveSchedulerPair有一个ExclusiveTaskScheduler看起来可以用。 Provides task schedulers that coord...

可疑的ArgumentException

项目做得久了，千奇百怪的问题都会遇到。大多数问题一看就知道怎么回事，有些问题则很有迷惑性，甚至让人百思不得其解。最近用户报告了一个错误，分析日志后发现往一个ObservableCollection<T>里面插入数据的时候抛出了System.ArgumentException，类似下面这样。看起来是内部出现了InvalidCast，问题是这里的xxx确实是yyy类型，不...

慎用隐式类型转换

.Net允许用户自定义运算符operator来实现两个类型之间的转换以提高代码灵活性。自定义运算符分为显式和隐式两种。显式运算符需要在代码中明确地把目标类型写出来，隐式运算符则由编译器自动检测和推断类型再生成相应代码。比如有下面这样一个类型，可用于根据string类型的id查找一个由泛型参数T指定的对象。 1 2 3 4 5 6 public sealed class Look...
