Introduction Among simulation engineers, it is well accepted that the solution of a PDE can be envisioned as the following three general steps (actually, this was also my premature understanding during the early era of my study on numerical simulatio…

在上一篇日志中,我简要介绍了如何围绕Emacs Org mode构建个人任务管理系统的基本思路与方法.因为Org mode体系庞大.功能繁杂,本文仅以提纲契领的方式介绍不同环节在Org mode中的操作与实现.更为具体与精密的功能机制和实施细节以查阅Org mode参考手册为宜. 定义任务状态关键词 变量org-todo-keywords用于指定可给任务赋予的状态关键词.该变量的值为一组序列(sequence)构成的列表.每一个序列以符号type或sequence开头,其后则是一组用于定义任务状…
