mysql - SQL Group By with Sum for each date and using max date -

-
i've seen lot of similar questions nothing quite nails particular problem. i have table storing multiple positions each account. changes stored deltas. take example on day 1 following... ac_id | pos_id | asat | val 1 | 1 | 2016-01-01 | 100 1 | 2 | 2016-01-01 | 200 the total value ac_id 1 300 on 01/01/2016.the next day may update be... ac_id | pos_id | asat | val 1 | 1 | 2016-01-01 | 100 1 | 2 | 2016-01-01 | 200 1 | 2 | 2016-01-02 | 250 now total value ac_id 1 350. because new record pos_id 2 overrides previous, value pos_id 1 has not changed. in order remove pos_id 1 table change like... ac_id | pos_id | asat | val 1 | 1 | 2016-01-01 | 100 1 | 2 | 2016-01-01 | 200 1 | 2 | 2016-01-02 | 250 1 | 1 | 2016-01-03 | 0 now value changes 250 on day 3. i can calculate value @ given date subquery so select sum(val) position p1 p1.asat = (select max(p2.asat) position

javascript - Hide user input in PhantomJS / CasperJS -

-
i have casperjs test suite in have fill login form user name , password. since don't want put password code did this: system.stdout.writeline("please enter password:"); var password = system.stdin.readline(); this.fill('form:first-of-type',{ 'username': user, 'password': password },true); this works, leaves password on console can read it. there way hide actual input view, or display ******** in place? or there perhaps approach problem have missed? edit: tried using execfile , doesn't when try run read , returns nothing ever happened. other external programs work fine. i found crude workaround: system.stdout.write("please enter password:"); var password = system.stdin.readline(); system.stdout.write("\033[1aplease enter password: \n"); will move cursor 1 line , print on password. problem remains, hides password after has been entered. if watching type, won't much. @

ruby : when to use 'load' to load file instead of 'require' -

-
this question has answer here: when use `require`, `load` or `autoload` in ruby? 4 answers i know basic difference between load , require statement. load loads file multiple time if loaded , require loads file once. i want know when use load statement on require statement. if possible please explain small example. thanks, as know, load re-loads file, if loaded; whereas require loads file once. as such, should (for performance reasons) use require instead of load . using load can useful if file changes state - although rare thing happen. typically, load geared more implementing customized runners ruby code loading classes , modules in projects - example, it's used capistrano . or common use when developing/debugging project open console, can use: load 'filename_i_just_edited' refresh code state, rather re-starting console.

PHPExcel cell height only works on empty cell -

i've read couple of examples on google cannot find issue. to set cell height use: $objphpexcel->getactivesheet()->getdefaultrowdimension()->setrowheight(-1); this set cell height "auto". guess text/data deside it's height?! i have tried several values like: 4, 10 etc.. strange cell without text change height. i'm thinking: text/font has margin-top value? cannot see type of height limit, should not prob. code //set font size $objphpexcel->getactivesheet()->getstyle("a1:i".$highestrow)->getfont()->setsize(4); //set row size $objphpexcel->getactivesheet()->getdefaultrowdimension()->setrowheight(6); example i'd cell height height text! the row height limit 409.50 (546 pixels), ms excel limit officeopenxml (xlsx)format. it's phpexcel doesn't enforce it. and if @ of examples (such 01simple.php ) you'll see height being set automatically rows 8 , 10. in case, looks though have
