-
i'd start using mailchimp api create utility pulls metrics user's account, such subscribers, last campaign date (not sure if 1 available yet), open rate, etc. one critical issue i'm facing that, while have free mailchimp account, there no data in whatsoever (no lists, subscribers, campaigns, etc.), makes less ideal testing. so i'd know best option here, i.e.: should create dummy data manually (like add myself subscriber list , send myself emails?), or (mailchimp) provide "sandbox" account has richer test/dummy data in it? or, some other alternative... ps - i'm using mulesoft integration task (i mention because perhaps info answer). mailchimp doesn't provide 'sandbox' account api testing. think best bet subscribe , play around. i've found mailchimp's api super easy use , mighty documented, imagine won't have trouble figuring out without sandbox play in. btw: last campaign date pulled campaigns/list output...

how can time zone detail per date. example : entered date 23/06/2015 , standard time zone detail per dst / non dst date. @ time america/godthab (gmt-03:00) greenland dst , asia/baku ((gmt+04:00) baku, tbilisi, yerevan) non dst. you can use javascript gettimezoneoffset() method: the gettimezoneoffset() method returns time difference between utc time , local time, in minutes. example, if time zone gmt+2, -120 returned. see this information. you can use momentjs , looks perfect.

Are there fixed memory allocated for Stack and Heap? -

i understand fact stack grows upwards , heap grows downwards or vice-versa (architecture dependent). but, couldn't find details how it's implemented, doubt is, every process memory block allocated, there restriction on, how max chunk can used stack or heap? or there no restrictions till whole allocated memory consumed? yes, processes have predetermined stack sizes. have ever tried recurse method/function much? stackoverflow exception. doesn't mean you've went through entire computer's memory. os controls distribution of stack , heap memory each process.
