lets assume have large data set per below schema layout id,name,city --------------- 100,ajay,chennai 101,john,bangalore 102,zach,chennai 103,deep,bangalore .... ... i have 2 style of pig code giving me same output. style 1 : records = load 'user/inputfiles/records.txt' using pigstorage(',') (id:int,name:chararray,city:chararray); records_grp = group records city; records_each = foreach records_grp generate group city,count(records.id) emp_cnt; dump records_each; style 2 : records = load 'user/inputfiles/records.txt' using pigstorage(',') (id:int,name:chararray,city:chararray); records_each = foreach (group records city) generate group city,count(records.id) emp_cnt; dump records_each ; in second style used nested foreach. style 2 code run faster style 1 code or not. i reduce total time taken complete pig job.. so style 2 code achieve ? or there no impact in total time taken? if confirms me can run similar code in cluster large d...

for example, init set [1,2,3, ...,100]. usually, follows: for(int = 1;i <= 100;i++ ){ set.add(i); } is there method more conveniently? such somemethod(startindex, endindex, step); by using that, can init set [1,2,3,4,5] or [1,3,5,7,9] or others. you can use java 8 streams. for example : set<integer> myset = intstream.range(1,101).boxed().collect(collectors.toset()); or odd numbers : set<integer> myset = intstream.range(1,101).filter(i->i%2==1).boxed().collect(collectors.toset()); intstream.range easy way obtains numbers in given range. then can apply filters if want of numbers. finally can collect them collection wish.

given following code: package main import ( "fmt" "runtime" "time" ) func f(from string) { := 0; < 3; i++ { fmt.println(from, ":", i) //runtime.gosched() } } func main() { runtime.gomaxprocs(runtime.numcpu()*2) time.sleep(100) go f("i not parallel") go f("neither me") var input string fmt.scanln(&input) } the output in cases is: i not parallel : 0 not parallel : 1 not parallel : 2 neither me : 0 neither me : 1 neither me : 2 and sometimes: neither me : 0 neither me : 1 neither me : 2 not parallel : 0 not parallel : 1 not parallel : 2 when runtime.gosched() uncommented seems ok. have tried changing gomaxprocs number 2 numcpu, number of goroutines, cycles: none work in parallel. why strange behaviour? edit: ok, seems context-switching heavy work , not done without reasonable matters. 1 thing sti...

i'm using mandrill api php. i sending mail message: $result = $mandrill->messages->sendtemplate($template_name, $template_content, $message); $mandrill_return_data = current($result); since message content saved 24 hours, retrieve html sent , save db. $message_content = $mandrill->messages->content($mandrill_return_data['_id'])['html']; unfortunately, doesn't work , returns following error: a mandrill error occurred: mandrill_unknown_message - no message exists id '446740d7b61e4403b11379db4e1d45b0' i did googling , found this answer , explains takes few minutes index message in system , noticed case. trying figure out solution on how retrieve message content html , save db. i suppose use cron job run every few hours or after sends message, or run ajax command retrieve message content html after specified timeout, both of solutions seem hacky. i'm hoping more elegant solution doesn't require whole lot of addi...

i writing in php create virtual file system using webdav. i trying head around propfind request method. rfc 4918 mentions it, i’m not sure understand. can clarify this: what role of depth value (0, 1, infinity)? has folders vs files? why client make multiple propfind requests on folder? i think might me sort out of rest. thanks what role of depth value (0, 1, infinity)? has folders vs files? for directories: depth 0: retrieve properties of directory depth 1: 0 + properties of files in directory depth infinity: 1 + properties of files in sub-directories of directory (recursively) for files has no effect. the depth applies other webdav methods.

i using data tables in application. while sorting column records reset.means, if on page 2,3,4,etc , if click on header sort data, data gets reset , on first page. want sort data page on currently. possible? using default code $(document).ready(function() { $('#example').datatable( { "processing": true, "serverside": true, "ajax": "scripts/server_processing.php", "deferloading": 57 } ); } ); see answer if want sort current page only. agree it, there little no sense that. however, using datatables api can stay on same page when sorting occurs. the solution store current page number when user changes page or performs search: var cur_page = 0; $('#example').on('page.dt search.dt', function(){ var info = table.page.info(); cur_page = info.page; }); then when user sorts page, need restore page. reason order.dt event triggered again when change page...
