i have apache server 32 gb of ram. when start server , execute top see resources show me cpu @ 95 percent. doesn't normal behaviour , after few minutes raises: apache cannot allocate memory fork unable fork new process i don't know how solve problem. tips? i had same problem fix there 2 options: 1- move micro instances small , change solved problem (micro instances on amazon tend have large cpu steal time) 2- tune mysql database server configuration , apache configuration use lot less memory. tuning guide low memory situation such one: http://www.narga.net/optimizing-apachephpmysql-low-memory-server/ (but don't use suggestion of myisam tables - horrible...) this 2 options make problem much less happening .. still looking better solution close process done , kill ones hang in there .

i have several apps on google play extensively use gcm , have been working quite time now. but, of sudden (aug 12, 2015), gcm returning "notregistered" when server posts message it. this happening enough cause big problems messaging can no longer trusted. the last part of web response stream is: [{"error":"notregistered"}]} i log registration id along response stream , registration id attempted use same 1 has been used phone. apps new registration id when first ran necessary application uninstalled , reinstalled make app work again. has changed? oddly, (or not) problem has occurred on phones running 5.1 lollipop. did possibly miss breaking change? thanks, dean if using googlecloudmessaging register , 1 possibility these users received upgrade of app. see latest edit eran's answer here .they need re-register gcm. consider using latest registration method using instance ids, has listener token refresh when needed.

i have been using following functions invert matrices in lapack: dgetrf() dgetri() however, subroutine dgetrf() considers partial pivoting. question: there other subroutine in lapack/blas replace dgetrf() without pivoting. also, know if there subroutine uses gaussian elimination matrix inversion instead of lu decomposition. the list of computational routines available in lapack can found here - scroll bottom of page, table 2.8. far can tell, methods general matrices use factorization perform inversion. there no subroutine uses ge compute inverse. related pivoting, suspect unless know doing, should not use method without partial pivoting. partial pivoting not terribly expensive in terms of performance, provide improved numerical stability . far aware, gaussian elimination used partial pivoting . in particular algorithm breaks if element on main diagonal 0 (for obvious reason). furthermore if value of pivot maximised numerical accuracy of solution improved. if g...

hi filter out of announcement on website following script gdata_even=soup.find_all("li", {"class":"list2col "}) gdata_odd=soup.find_all("li", {"class":"list2col odd "}) finally take of announcements in gdata depending on whether item has word: for l in range(len_data): if _checkdate(gdata_even[l].text): if _checkwordsv2(gdata_even[l].text): pass else: initial_list.append(gdata_even[l].text.encode("utf-8")) if _checkdate(gdata_odd[l].text): if _checkwordsv2(gdata_odd[l].text): pass else: initial_list.append(gdata_odd[l].text.encode("utf-8")) the problem facing gdata_even[l] , gdata_odd[l] has following output: <li class="list2col "><div class="indexcol"><span class="date">25 aug ...

say have array want find equilibrium index , why imperative style faster functional style, , logic behind algorithm (imperative's)? functional style: def eq_indices(list) list.each_index.select |i| list[0...i].inject(0, :+) == list[i+1..-1].inject(0, :+) end end imperative style: def eq_indices(list) left, right = 0, list.inject(0, :+) equilibrium_indices = [] list.each_with_index |val, i| right -= val equilibrium_indices << if right == left left += val end equilibrium_indices end because in functional style, sum of left , right sides calculated scratch each potential equilibrium, whereas in imperative style, sum calculated once, , single subtraction , addition performed each potential equilibrium.

i want user enter 8 numbers. if enter less 8 numbers, program exit. what if statement should use? should put in loop sum += if sum not 8 exit? this got far doesn't work out: int main() { int i, numb; int sum = 0; // loop enter 8 numb printf("enter 8 numbers"); if (i=0;i<8;i++) { scanf("%d", &numb); sum =+i; if (sum < 8) exit(1); } return (0); } you want user enter 8 numbers , since have not mentioned sum, i'll assume doesn't matter is. remove inner if condition altogether , replace outer if loop. here code: for (i = 0; < 8; i++) { scanf("%d", &numb); //do whatever want number here

i have problem connect database. had problem few days ago when started using mac instead of dell. connection still working on dell. i'm using eclipse, tomcat server, mysql. have displayed on console. i hope helpful: you appear using non standard port number mysql command need reflect non standard port number. i little rusty on java try this string dataserviceurl = "jdbc:mysql://localhost:8889/majjane"; possibly using ip rather localhost help, woudl make faster if nothing else. string dataserviceurl = "jdbc:mysql://127.0.0.1:8889/majjane";
