my backbone code seems have crazy number of this.methodcall() type of invocations , i'd love able drop this , , call methodcall() directly inside view. see below code: app.main = backbone.view.extend({ el: '#main-div', // how call function without invoking "this"? setpagecookies: function () { console.log('setting page cookies called!'); }, initialize: function () { // saw online possible solution, seems affect scope of "this" _.bindall(this, 'setpagecookies'); // works: this.setpagecookies(); // however, i'd able call instead: setpagecookies(); } }); firstly - this.setpagecookies() , setpagecookies() have drastically different meanings. the way achieve calling setpagecookies() without this make setpagecookies function declaration: function setpagecookies() { } backbone.view.extend({ setpagecookies: setpagecookies,

i have mapping similar this: jsonexample this represents changelog structure. each document represents object properties. these properties can changed @ dates. limit space, keeps track of changes instead of updating whole object 1 updated field example. the goal query object based on given date. result should object properties on given date. later changes should discarded , changes matching or recent given date should returned. so nested query can retrieve whole object. want nested properties returned , sorted closest given date can find properties @ given date. is there way elasticsearch queries/filters , without parsing returned json , sort afterwards example java.

is possible change dcos template use spot instances? have looked around , there not seem information regarding this. okay, given dcos template , launchconfiguration slaves looks this: (i've shortened somewhat) "masterlaunchconfig": { "type": "aws::autoscaling::launchconfiguration", "properties": { "iaminstanceprofile": { "ref": "masterinstanceprofile" }, "securitygroups": [ ... ], "imageid": { ... }, "instancetype": { ... }, "keyname": { "ref": "keyname" }, "userdata": { ... } } } to started, need add spotprice property in there. value of spotprice is, obviously, maximum price want pay. you'll need more work around autoscaling, alarms , time of day. here's new launchconfiguration spot price of $1.00 per hour: "masterlaunchconfig": { "type": "aws::autoscaling:

what difference between jquery html callback function (source http://www.w3schools.com/jquery/jquery_dom_set.asp ) , jquery append function (source http://www.w3schools.com/jquery/jquery_dom_add.asp ) also ecsctly use of parameter index in jquery html callback function? callback used manipulate content of html element. here can put logic handle text provided , return modified text. in below code, adding original text new 1 return index. same way can put own logic handle text. $("#test1").text(function(i, origtext){ return "old text: " + origtext + " new text: hello world! (index: " + + ")"; }); while in append got choice add more text after existing text , nothing can done extra. in below example, appending new text existing text. $("p").append("some appended text.");

what i'm trying take text file bunch of strings search for, each on own line, , search each 1 of these strings in file (check.txt). want output text file list of strings couldn't found. i've tried few things far. /f "tokens=*" %%a in search.txt ( @echo on findstr %%a check.txt if errorlevel 1 echo %%a fail > fail_match.txt ) another attempt made (this 1 tell me if whole list or not) @echo on findstr /g:search.txt check.txt > a_match.txt if errorlevel 1 echo bad > a_match.txt i realize these incredibly basic, , i'm sure there's easy answer don't understand. i'm not programmer; want make job lot easier (and faster). to clarify, list of things search in search.txt, list of things check them against check.txt. check.txt json file, it's 1 enormous line. don't know if make difference or not. want list of lines in search.txt not in check.txt. your search scheme seems naive on 2 fronts: 1) json not guaranteed

calling std::min() empty initializer list not compile (all question can stated in same way std::max() ). code: #include <iostream> #include <algorithm> int main() { std::cout << std::min({}) << "\n"; return 0; } with clang gives error: test.cpp:6:17: error: no matching function call 'min' std::cout << std::min({}) << "\n"; ^~~~~~~~ algorithm:2599:1: note: candidate template ignored: couldn't infer template argument '_tp' min(initializer_list<_tp> __t) i can see why case not allowed, because difficult agree on sensible value return in case. however, technically speaking code not compile because template parameter cannot deduced. if force parameter code compiles crash: #include <iostream> #include <algorithm> int main() { std::cout << std::min<int>({}) << "\n"; return 0; } $ clang++ -std=c++11 test.cpp -o test

here 1 way problem unnecessary usage of output screen. lenth=printf("%d",num);// or lenth=printf("%s",str); how find length without having output printf? you can use snprintf() empty buffer (i.e. pass null pointer), return number of characters have been written buffer if there enough space in it: int length = snprintf(0, 0, "%d", num); this way, don't need use actual buffer , won't print on stdout printf() does.

the way how indexing in database works: refering answer xenph yan creating index on field in table creates data structure holds field value, , pointer record relates to. index structure sorted, allowing binary searches performed on it. the way understood orc indexing is, orc keeps statistics (min, max, sum) rows every 10'000 rows (by default )and if query data looks @ statistics figure out if needs read row chunk or not. so correct orc indexing not sort data? i have 69 column large table unstructured data , able perform ad-hoc queries on every column. so, able sort every column through index (or @ least of them). there no 'key' column in data get's queried rapidly. hive has been designed pseudo-sql front-end running (long) batch jobs on (massive) data sets. can run "ad hoc queries" forget "rapidly" . besides, when index column in database (i.e. create index command in sql), index entire, exact value of each row. if

in ssms, can create global temp variable in 1 batch , use in another. this: create table ##temp (col1 int) go drop table ##temp go with sqlcmd, create global temp table in 1 call , not exist in second. sqlcmd -s localhost -d tempdb -e -q "create table ##temp (col1 int)" sqlcmd -s localhost -d tempdb -e -q "drop table ##temp" msg 3701, level 11, state 5, server vatllxt7lgbare2, line 1 cannot drop table '##temp', because not exist or not have permission. is global temp table not supposed stick around until server reset? yes that's correct cause global temporary table exists in connection/session created , gets dropped automatically if connection closes. in case, first sqlcmd creates table sqlcmd -s localhost -d tempdb -e -q "create table ##temp (col1 int)" and connection closes drops temporary table , in next connection doesn't exists anymore sqlcmd -s localhost -d tempdb -e -q "drop table ##temp"

in powershell, can this: $useraccount = get-aduser -filter { name -like "*smith*"} and find user(s), when this: $namefilter = "smith" $useraccount = get-aduser -filter { name -like "*$namefilter*"} nothing found. why? -filter looks accepts script block where-object, it's string. if use curly braces syntax, tends treat literal string, variables won't expand. try: $useraccount = get-aduser -filter "name -like '*$namefilter*'"

hi have table 2 columns (wid,dt) data.. wid dt ------- 10 11 12 b 10 b 11 c 10 c 13 if pass a,b in input should output 10 , 11. intersection of dt. if pass a,b,c in input should 10 output. if pass input 10,11,12 output.. input dynamic depends on conditions ui. how achieve in query... here's way doesn't require add intersect each item in list pass in parameter. can't guarantee peform on large data sets, however, you'd have test data! this first example shows results mimics effect of multiple values of parameter being passed in @ same time (mainly show results of different test cases mentioned): with sample_data (select 'a' wid, 10 dt dual union select 'a' wid, 11 dt dual union select 'a' wid, 12 dt dual union select 'b' wid, 10 dt dual union select 'b' wid, 11 dt dual union select 'c' w

i trying use java format time in milliseconds date in utc. have following code: long ms = 1427590800000; calendar cal = calendar.getinstance(timezone.gettimezone("utc"), locale.root); cal.settimeinmillis(ms); date date = cal.gettime(); simpledateformat dateformat = new simpledateformat("yyyy-mm-dd hh:mm:ss"); system.out.println(dateformat.format(date)); // 2015-03-29 02:00:00 this printing time in bst (i.e. using default time-zone) rather utc. seems time-zone being set on calendar has no bearing on date being printed. the actual time in utc shown following python snippet: import datetime ms = 1427590800000 print datetime.datetime.utcfromtimestamp(ms/1000.0) # 2015-03-29 01:00:00 setting default jvm time-zone "utc" results in correct date being printed, doesn't seem safe solution. you need set timezone formatter before formatting if want desired timezone. use dateformat.settimezone(timezone.gettimezone("utc")); , cal
