is possible load added module @ run-time? i have added optional module ear, started jboss , added optional module @ run-time using cli. load module though had restart jboss not looking for. is there way load without restart using jboss cli? you can try jrebel , hot deploy stuff have trial version. if using jboos 7.0.1 (community project). you can go jboss administrative panel, there in profile settings open core - deployment scanners. turn on auto deploy-exploded (set true), , set scanner time per requirement ( default 5000 ms) . it.

say have: class mycreate(createview): template_name = 'template.html' success_url = reverse_lazy('blabla') form_class = myform and suppose in template want add back button. lead me same page success_url . solution override get_context_data in mycreate class , add {'back': self.get_success_url()} context . the implications have more createviews , had create contextmixin back button. there other easier solution? accessing success_url directly in template? thanks as can see in django (1.7) implementation of contextmixin , must have access view instance our templates: def get_context_data(self, **kwargs): if 'view' not in kwargs: kwargs['view'] = self return kwargs so can access success_url in templates: {{ view.get_success_url }}

i using blue-daemons fork of daemons gem (since second 1 looks totally abandoned) along daemons-rails gem, wraps daemons rails. the problem daemon eats cpu when it's idle (10-20 times higher it's performing job). by being idle, mean have special flag - status.active? . if status.active? true , perform job, if it's false , sleep 10 secs , iterate next step in while($running) do block , check status again , again. i don't want hard stop job because there sensitive data , don't want process break it. there way handle high cpu usaget? tried sidekiq, looks it's primary aim run jobs on demand or on schedule, need daemon run on non-stop basis. $running = true signal.trap("term") $running = false end while($running) while status.active? ..... lots of work ..... else sleep 10 end end

i read uint8_t , uint16_t types registers "cast" them floats. wich optimal way? there's no need cast; integer types implicitly convertible floating-point types. uint8_t u8 = something; uint16_t u16 = whatever; float f1 = u8; float f2 = u16; 8 , 16-bit integer values should represented exactly. larger types might lose precision.

can please explain in situation supposed use arraylist instead of simple array , diffrence between these 2 , how intialise arraylist.i new java use example if possible whenever don't know size created, can use arraylist.. if want speed access, can use array.

what best way display block of scrollable text in spritekit game? within scene. write own algorithm using sklabels seems there should better way. there no component in spritekit out of box, it's quite simple simulate scrolling text handling touches. you have handle limit , paging if want have bouncing, acceleration , others, there plenty of examples around here start from. keep in mind sklabelnode doesn't support multiline out of box, have create own multiline label (basically 1 label per line). if text want render long may struggle create , not smooth, work fine. the other option use uikit makes simple create using uiscrollview , uitextview , present on top of skview contains scene. doesn't work if need within scene works wonders if want display big chunks of texts instructions or legal texts.

here code : #include<stdio.h> #include <stdlib.h> #define len 2 int main(void) { char num1[len],num2[len]; //works fine //char *num1= malloc(len), *num2= malloc(len); int number1,number2; int sum; printf("first integer add = "); scanf("%s",num1); printf("second integer add = "); scanf("%s",num2); //adds integers number1= atoi(num1); number2= atoi(num2); sum = number1 + number2; //prints sum printf("sum of %d , %d = %d \n",number1, number2, sum); return 0; } here output : first integer add = 15 second integer add = 12 sum of 0 , 12 = 12 why taking 0 instead of first variable 15 ? could not understand why happening. it working fine if using char *num1= malloc(len), *num2= malloc(len); instead of char num1[len],num2[len]; but should work fine this. edited : yes, worked len 3 why showed undefined behav...

nosql databases couchbase hold lot of documents in memory, hence enormous speed it's putting greater demand on memory size of server(s) it's running on. i'm looking best strategy between several contrary strategies of storing documents in nosql database. these are: optimise speed putting whole information 1 (big) document has advantage single information can retrieved memory or disk (if purged memory before). schema-less nosql databases wished. document become big , eat lot of memory, less documents able kept in memory in total optimise memory splitting documents several documents (eg using compound keys described in question: designing record keys document-oriented database - best practice when documents hold information necessary in specific read/update operation allow more (transient) documents held in memory. the use case i'm looking @ call detail records (cdr's) telecommunication providers. these cdr's go hundreds of millions typically ...

i've been going nuts problem hours, , i've been redoing on , over! @ point think i'm seeing numbers flying around me. anyway, i'm supposed write program finds correct amount of money pay each month on 1 year, pay off debt on credit card. program, there's few conditions must met. it must done using bisection search ((low + high) / 2) there's set balance there's annual interest rate. here's code @ moment, , i'm getting infinite loops. doing wrong here? balance = 320000 annualinterestrate = 0.2 monthly_interest = float(annualinterestrate) / 12.0 lower_bound = float(balance / 12) upper_bound = (balance * (1 + monthly_interest)**12) / 12.0 epsilon = 0.01 ans = float(lower_bound + upper_bound) / 2 while abs((balance * (1 + monthly_interest)**12) / 12.0) >= epsilon: ans = float(lower_bound + upper_bound) / 2 total = float(ans * 12) new_balance = 0 interest = 0 month in range(0, 12): interest += ans + (1 + m...

i having trouble script link custom actions. building sharepoint app, , added site-scope custom action pointing script file in style library, want particular script injected pages of sharepoint site. while works in situations, script link injection breaks without apparent reason under conditions. example, when arrive on root web, script injected. but, if go link within web (for example home or site contents), file supposed injected not fetched style library , therefore never injected, resulting in uncaught referenceerror when try call 1 of script's function. weirdest part page refresh through ctrl+f5 fetch script file without problem, regardless of page's ability fetch script file when first accessed. keep script until accessed through link again. i've read on sharepoint caching , thinking may cause of problem, trouble these articles talk cache-induced errors when updating file, while trying access it. one thing note that, due limitations, adding script link cu...
