reading some coffeescript and go books.

to setup a coffeescript dev env, can use netbeans, just install nodejs and coffee script plugins will do.

some of the terms I know what it is but didn't know how to call it:

Interpolated Strings: x = "hello #{var}"
Literal Strings: x = 'hello #{var}'
Heredocs: <<<HTMLDOC HTMLDOC;
Ternary: x == y ? a : b
Splats: (etc...)

a note on Programming in Coffeescript, page 153

class User
  constructor: (@name) ->
 sayHi: ->
    console.log "Hello #{@name}"
    
bob = new User('bob');
mary = new User('mary');

log = (callback) ->
  callback();
  
log(bob.sayHi)
log(mary.sayHi)

above prints Hello undefined, it won't work because when bob.sayHi is invoked, it losts its origin already, what is invoked is just a reference to function(){...}.

finished Programming in Coffeescript, didn't do the to-do app in last few chapters. i think nodejs gives a great reason to use coffeescript, and will try that.

didn't read perl book for a long time. borrowed Intermediate Perl, because i found it is more modern than other books in library. and this book is quite well.

there is one mantisbt plugin for kanban, changed few codes it works fine:

change all require_api to require_once
FILTER_PROPERTY_STATUS to FILTER_PROPERTY_STATUS_ID
add FILTER_PROPERTY_SORT_FIELD_NAME => 'priority' if want to sort by priority
change css/html for missing images

also there is another simple PHP+SQLite kanban board, which also pretty good.

I gave up reading Intermediate Perl. I think Ruby makes more sense, and should stop wasting time on it, will read some Python instead.

I decided moving to heroku to save cost, since I'm not doing anything on this VPS for 5 months. I had many plans before, but too busy to get close to any of them.

Made the decision will move this site to nodejitsu, heroku sleeps too long for a first visit :-P.

I also need to drop the self-host git repository and move to 3rd party provider, will change back to mercurial as well.
