the lword project
lword helps you memorize new words.
you are asked to spell each new word defined in a word-file.
the word-file is a simple text file.
format is:
<word>
<explainations, hints> without empty newline between them.
<newline>
<word>
<explainations, hints> without empty newline between them.
<newline>
...
----start sample word file----
fahrenheit
/ˈfarənˌhīt/
the temperature scale starts in F
celsius
/ˈselsēəs/
the temperature scale starts in C
----end sample word file----
lword will have a db about which words you already known very well and which
words you constantly make mistakes on.
it also re-prompt old memorized word to you according to the famous the
forgetting curve [1].
* the forgetting curve
一般记住后，在5分钟后重复一遍，20分钟后再重复一遍，1小时后，12小时后，1天后，2
天后，5天后，8天后，14天后就会记得很牢。

** phonemic symbols in words file
to show KK(Kenyon and Knott) phonemic symbols / IPA(International Phonetic
Alphabet), you need a good font.
Lucida Sans Unicode is said to support IPA.
The IPA-SAM fonts are proprietary copyrighted Encore fonts created using
Typecaster software supplied by the Summer Institute of Linguistics.
** db design
| word | string | the word |
| | | |
| count | int | how many times the user has typed the word |
| wrong_count | int | how many times the user got it wrong |
| | | |
| session_count | int | how many sessions has this word mentioned? |
| last_session | timestamp | when is last session |
** sqlite
you can run sqlite in script like this
sqlite3 ex1 'select * from tbl1'
syntax:
sqlite3 <db-file-name> <SQL-statement>
* I miss Javscript list and object notation now that I'm writing python code
