在数据科学领域，数据的复杂性往往是不可避免的。正如文中所言，数据的复杂性恰恰体现了数据科学的存在意义。数据科学家常常需要面对数据清洗、质量控制、数据挖掘等一系列工作，甚至在项目接近尾声时，对数据的有效性仍然存在疑问。
在面对数据挖掘过程中的复杂情况时，一个良好的习惯是快速记录关键信息。就像文中提到的 自由博客系统之一–瞬时捕捉 一样，这种记录方式有利于方便进行多任务并行处理，提高工作效率。
因此，在实践中，使用以下模板来捕捉关键信息是非常有用的：
(setq org-capture-templates
'(("c" "Collaborator" item (file+headline (lambda () (concat (string-trim (shell-command-to-string "~/bin/projectJump.sh INFO")) "/README.org")) "Collaborator")
"- %?"
:empty-lines-after 1
:empty-lines-before 1)
("pC" "Collaborator protocol" item (file+headline (lambda () (concat (string-trim (shell-command-to-string "~/bin/projectJump.sh INFO")) "/README.org")) "Collaborator")
"%(set-frame-name \"capture\")- %?"
:empty-lines-after 1
:empty-lines-before 1)
("d" "Project type" item (file+headline (lambda () (concat (string-trim (shell-command-to-string "~/bin/projectJump.sh INFO")) "/README.org")) "Project type")
"- %?"
:empty-lines-after 1
:empty-lines-before 1)
("pD" "Project type protocol" item (file+headline (lambda () (concat (string-trim (shell-command-to-string "~/bin/projectJump.sh INFO")) "/README.org")) "Project type")
"%(set-frame-name \"capture\")- %?"
:empty-lines-after 1
:empty-lines-before 1)
("n" "Note" entry (file+headline (lambda () (concat (string-trim (shell-command-to-string "~/bin/projectJump.sh INFO")) "/README.org")) "Note")
"* %? :%(string-trim (shell-command-to-string \"~/bin/projectJump.sh base\")):\n%U In file: [[file://%F::%(with-current-buffer (org-capture-get :original-buffer) (number-to-string (line-number-at-pos)))][%f]]\n#+BEGIN_SRC %(replace-regexp-in-string \"-mode\" \"\" (with-current-buffer (org-capture-get :original-buffer) (symbol-name major-mode)))\n%i#+END_SRC"
:empty-lines-after 1
:empty-lines-before 1)
("p" "Plan about code" entry (file+headline (lambda () (concat (string-trim (shell-command-to-string "~/bin/projectJump.sh INFO")) "/README.org")) "Plan")
"* TODO %? :%(string-trim (shell-command-to-string \"~/bin/projectJump.sh base\")):\n%U In file: [[file://%F::%(with-current-buffer (org-capture-get :original-buffer) (number-to-string (line-number-at-pos)))][%f]]\n#+BEGIN_SRC %(replace-regexp-in-string \"-mode\" \"\" (with-current-buffer (org-capture-get :original-buffer) (symbol-name major-mode)))\n%i#+END_SRC"
:empty-lines-after 1
:empty-lines-before 1)
("pP" "Plan protocol" entry (file+headline (lambda () (concat (string-trim (shell-command-to-string "~/bin/projectJump.sh INFO")) "/README.org")) "Plan")
"%(set-frame-name \"capture\")* TODO %? :%(string-trim (shell-command-to-string \"~/bin/projectJump.sh base\")):"
:empty-lines-after 1
:empty-lines-before 1)
("pF" "File or folder annotation protocol" entry (file+headline (lambda () (concat (string-trim (shell-command-to-string "~/bin/projectJump.sh INFO")) "/README.org")) "File or folder annotation")
"%(set-frame-name \"capture\")* %(if (f-file-p \"%:link\") \"File: \" \"Folder: \")[[file://%:link][%(f-filename \"%:link\")]] :%(string-trim (shell-command-to-string \"~/bin/projectJump.sh base\")):\n- Note taken on %U \\\\\ \n %?"
:empty-lines-after 1
:empty-lines-before 1)))
其中，
(org-agenda nil "p")的设置方法在数据科学杂谈之八–日程管理文中有描述。
(string-trim (shell-command-to-string \"~/bin/projectJump.sh base\"))
为前文“数据科学杂谈之五–奇异博士的传送门”中描述的跳转方法。
除了一些常见的org-protocol之外，模板pF非常有用，例如其与文件管理器ranger结合，可对当前文件进行快速注释。
在ranger的配置文件rc.conf中，添加
map ,fan shell -w ~/bin/file_annotation_org.sh $(realpath %s)
而file_annotation_org.sh内容为：
emacsclient -t -u -q -s tmux:$(tmux display -p '#S-#I') -a '' "org-protocol://capture?template=pF&url=${1}"
此外，因为lisp具备无与伦比的强大扩展性，所以用户可以任意地定制和修改Emacs的各种行为。
例如，我喜欢在当前工程文件夹的任意位置，通过按,pat直接弹出当前工程的日程安排和待办事项。
然后，按q直接退出。
这样ranger的rc.conf中直接设置
map shell -w emacsclient -t -s tmux:$(tmux display -p '#S-#I') -a '' --eval "(progn (set-face-background 'default \"unspecified-bg\" (selected-frame)) (advice-add 'org-agenda-quit :after #'my-temporary-org-agenda-quit-hook) (org-agenda nil \"p\"))"
此处，
(set-face-background 'default "unspecified-bg" (selected-frame))
用来去除新建的emacsclient的背景，因为我喜欢没有任何背景颜色。 而
(advice-add 'org-agenda-quit :after #'my-temporary-org-agenda-quit-hook)
用来在退出org-agenda之前，添加一个钩子，用来删除emacsclient。
而这个挂在钩子上的函数能够自己把自己从钩子上卸下来：
(defun my-temporary-org-agenda-quit-hook ()
"Function to be run temporarily. remove whole frame"
(delete-frame (selected-frame))
(advice-remove 'org-agenda-quit #'my-temporary-org-agenda-quit-hook))
有了以上各种手段，诸位可以歇斯底里、快意恩仇、大杀四方！
