about title

• spend a lot of time learn org mode advanced techniques. tired but feel gain something.

feeling

• when I play skull girls, I spend a lot of time just press without thinking, even without intention. It comes out that I have little progress in game.
• But after a long time, I wake up (or something like this) and I practice with intention and patience. Then I feel growth in power.
• It means that A LOT OF TIME is needed to get into a normal study state
• I should continue to keep the habit of study and thinking so that I can escape chaos status quickly
• another thing. it happens today, I feel not happy no matter what reason. After a time of playing game with that bad mood, I recovered.
• So maybe it means stay with bad mood, it will go away after sometime. But don’t do something addictive.

org mode task status

• in emacs, the built-in task status are TODO and DONE. If want more, can define them by self.
• example

#+SEQ_TODO: REPORT(r) BUG(b) KNOWNCAUSE(k) | FIXED(f)
#+SEQ_TODO: TODO(T!) | DONE(D@)3 CANCELED(C@/!)

• each SEQ_TODO defines one status sequence
• from official document, SEQ_TODO can by replaced by TODO.
• can define multiple status sequence
• status is seprated by space
• can add more functions in side ()
• char, will represents as shortcuts
• !, insert timestamp when shift to this status
• @, require input information when switched to this status
• @/!, means both
• | is used to seprate unfinished status from finished status
• org-todo-keywords is a configurable variable to set to make global effect

org mode LOGBOOK

• when taking a lot of notes, you might want to get the notes out of the way into a drawer. Customize the variable org-log-into-drawer to get this behavior – the recommended drawer is called LOGBOOK. You can also overrule the settings of this variable for a subtree by setting a LOG_INTO_DRAWER property.

netcat send files never ends

• in Ubuntu, send files with an additional -N: nc -N ip port < file
• it is because netcat has different implementation, and in some implementation, the file EOF will not be treated as sending’s end. And this cause it hang a lot of time and never ends.

the workflow of org mode

• open any buffer or just a scatch buffer
• start to collect things and make plan
• they all be captured into INBOX
• when all things are captured, browse INBOX and refile the real task into PLAYGROUND
• in PLAYGROUND, give todo items more detail, such as schedule time, small task, information related and so on
• Then, open DAILY-PLAN, and fill in the daily-plan template with tasks in PLAYGROUND
• Finally, according to DAILY-PLAN, finish them one by one. (Meanwhile, fill in more details and record time)
