我们发现我们明智地分层的架构已经像过于湿润的杂果布丁一样崩溃了。混乱的软件系统的特征是功能的相同性:具有领域知识并发送电子邮件和执行日志记录的API处理程序;“业务逻辑”类不进行计算但执行 I/O;以及一切与一切耦合,以至于改变系统的任何部分都充满了危险。这是如此普遍,以至于软件工程师有自己的术语来描述混乱:...
Content-Type Content-Type indicates the type of data to send or receive and determine the form and encoding method browsers will use to display data (mainly custom client files or media files). If no content type is specified, the type will be generated based on the file name extension. If...

Unlike [Python view] nodes, which use Python object metadata to determine the type of the object, there's no similarly reliable mechanism for [C++ view]. Generally speaking, given a Python value (that is, a PyObject reference) it's not possible to reliably determine which C/C++ structu...
