i part of team developing spring boot backend application, provides mobile applications data. along new feature need of loading resource @ backend, need provided mobile application arose. due fact resource important , making access resource effective loading once during startup, wondered if can tell spring boot not start without resource existing in file system. know annotation @postconstruct, loading resource there seems late. thanks in advance suggtestions @postconstruct can used make sure application has stuff need when starts db pooling etc. example, can throw illegalstateexception() if file not there , can stop application loading. ran quick test , works. can use them below. @postconstruct public void setup() { // check stuff need. if (condition) { throw new illegalstateexception(); } }

i have inherited markup similar html below. <div class="a b">how_can_i_select_ab_only</div> <div class="a b disabled">how_can_i_select_ab_and_disabled_only</div> i want select both elements individually. css selector .a.b selects both divs <div class="a b">how_can_i_select_ab_only</div> <div class="a b disabled">how_can_i_select_ab_and_disabled_only</div> what selector select class a.b.disabled , class a.b ? three ways how it: the first one, set styles .a.b , them remove them (override) .a.b.disabled . .a.b {color: red;} .a.b.disabled {color: grey} https://jsfiddle.net/p84s61gp/ the second way, use attr selector. [class='a b'] {color: red} https://jsfiddle.net/p84s61gp/1/ next, can use :not selector, support since ie9. .a.b:not(.disabled) {color: red} https://jsfiddle.net/p84s61gp/2/

i had request add google tag manager our website , added using dynamic tag manage (dtm). created page load rule , added script. client saying not working dtm adds code page iframe. there way can fix issue? alternative directly add in page. don't want go in route have update our page templates these tags. avoid adding tag manager code in other tag containers. built standalone tag management solution , google won't provide support if it's embedded in 3rd party solution. your best option select 1 tag management solution , stick that. having multiple tag managers kind of defeats purpose, no?

currently put hourly traffic (total number of input requests) of website in mysql table. keep data last 90 days. i want check every hour, lets 6th hour, has traffic increased/decreased beyond threshold last 7 days or last 30 days 6th hour traffic. basically, see pattern of traffic. different hours have different values. -> there alerting framework can use purpose? -> if yes, can suggest open source? -> if no, thinking of keeping running average of last 7 days / last 30 days in mysql table every hour. and according, write script generate alerts based on numbers. not sure whether should mean, median or standard deviation. can enlighten me there?

i'm trying build search query using laravel-5 seem generating wrong sql. here's code using: bookingdates::where('status', 'booked')->where('email', input::get('email'))->where('name', 'like', '%' . input::get('name') . '%')->where('date', $date)->get(); however user may not provide email. when happens, part of query ( where('email', input::get('email')) ) should omitted. example, query run if didn't provide email: bookingdates::where('status', 'booked')->where('name', 'like', '%' . input::get('name') . '%')->where('date', $date)->get(); is there easy/pretty way using laravel-5? thanks. you can build query in separate steps: $query = bookingdates::where('status', 'booked') ->where('name', 'like', '%' . inp...

while syntactically proficient @ javascript, clueless goes on under hood. running when , how javascript engine schedules it, if indeed it's scheduled in sense of word. clueless don't know terminology should use research it. i have assumed, hearing others parrot it, javascript engines can run 1 thread @ time. assuming true , function running when callback occurs, happens behind scenes? running function paused , callback executed or full stack of running function unwound, code in callback run. i clueless , shameful... how fit in ui thread in browser, how different in node.js sorry if question bit open ended, in end asking boils down -- should research(i.e google) learn more of this. the function being executed finishes execution before callback run. can implemented in different ways different engines. node not different , engine responsible executing javascript code shared browsers. since can't run 2 or more functions @ same time, , 1 function needs f...

my man page crypt function states that: "the return value points static data content overwritten each call." however, when using sha512 version (ie, salt starts $6$...), valgrind not seem agree. unless free pointer crypt returns, gets upset: 120 bytes in 1 blocks still reachable in loss record 1 of 1 @ 0x4c2bba0: malloc (in /usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so) 0x4c2df4f: realloc (in /usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so) 0x521f4d4: __sha512_crypt (sha512-crypt.c:437) conversely, valgrind fine if use des version (so salt not start $6$ or similar). what's going on here , behaviour explained anywhere? thanks in advance. edit: platform ubuntu 15.04 64-bit. here's program: #define _xopen_source 700 #include <unistd.h> int main(int argc, char** argv) { char *hash = crypt("password", "$6$salty"); return 0; } for crypt variations, preallocated buffer not big enough, allocates (via ma...

stored procedure: dbo.getldate select dateentered table1 id = 4, gid=5 result: executed new query verify: declare @ldate datetime exec @ldate = getldate 4,5 results: dateentered 2014-02-13 06:21:43.600 thus, working fine final stored procedure created: exec @ldate = getldate 4,5 select 1 in c# int? id = _database.executescalar() int?; here, every time null value only. selecting 1 still null value. reason this. you selecting string '1' , can't converted int? cast . hence getting null. use: select 1 --without single quotes or can use convert.toint32 like: int? id = convert.toint32(_database.executescalar()); consider following example: object obj = "1"; int? id = obj int?; you null cast "1" (string) int/int? fail.

i lose guessing how come given output . can please explanation? also, short , quick resources try similar questions? void main() { struct { char ch[10]; char *str; }; struct s1={"hyderabad","bangalore"}; printf("\n%c%c",s1.ch[0],*s1.str); printf("\n%s%s",s1.ch,s1.str); getch(); } ans: hb, hyderabadbangalore struct s1={"hyderabad","bangalore"}; assigns "hyderabad" ch , "bangalore" str . printf("\n%c%c",s1.ch[0],*s1.str); prints first character of strings. since ch array, ch[0] represents first character. since str character pointer, points first character of string here. so, *s1.str have value 'b' printf("\n%s%s",s1.ch,s1.str); prints characters of both strings. fundamentally, ch equal &ch[0] , address of first character in array. and, str pointer variable holds address of first character of string lite...
