every time publish our azure project (all machines in our team/at home well) asks re-enter our rdp password. this bit annoying means files check out , have keep entering password. the error message "the existing remote desktop credentials not loaded in environment. re-enter desired password". anyone got idea up? bit frustrating. answer because publishing different instances same configuration , not using fixed rdp cert. re-generating certificate each time. if have problem upload cert each cloud service deploying , use 1 cert across deployments.

i new php , had learning experience sharing here others who, me, may need find cause of error , because still don't know solution , sure there syntax haven't found yet need do. so, problem can demonstrated this: class sample { protected $foo = array(); public function magicsamplesetfunc($property, $key, $value) { $this->$property[$key] = $value; } } ... $s = new sample(); $s->magicsamplesetfunc('foo', 'somekey', 'someval'); obviously, isn't real code (nor have run it) minimal example explain situation. here have member variable foo array , generic function going try set key , value it. can var_dump $this->$property , see array, on $this->$property[$key] line error message: "warning: illegal string offset 'somekey' in ...". at first though saying 'somekey' illegal string use array offset, didn't make sense. and, if wrap in isset complains. first thing learned if have strin

is there possible race condition redis' ltrim , rpush? for instance, suppose redis list has these items: [1, 2, 3, 4, 5] and call ltrim list 4 -1 should slice list [5] but let's say: a millisecond after ltrim has started , before ltrim finished , thread pushing items list: rpush list 6 rpush list 7 when both 2 rpushes, , ltrims finished, resulting list consist of [5, 6, 7]? could possibly [5]? in other words, there possibility of race condition ltrim creating temporary list [5], , overwrites [5,6,7] [5] after 2 rpushes done? short answer: no, because commands atomic. honest answer: don't think because think operations atomic; however, website doesn't explicitly state atomic i'm 99.99999999% sure are. logical answer: redis single-threaded, there no other threads preempt ltrim command. race condition occur in single threaded application have explicitly jump out of ltrim operation before it's done , start doing else, doesn't mak

i'm noticing weird phenomenon in application. store objects in hashmap after submitting them server , remove them when response arrives. i noticed slow performance after running. upon checking, discovered memory usage stays @ 4gb , drops less 1 gb. suspect cleaning lot of objects that's why performance gets bad. so question why taking java garbage collect late? is, why wait until heap full , garbage collection? shouldn't collect garbage @ regular intervals. the objects gets stored in hashmap gets created right @ time, not long lived. this on linux (rhel), oracle jvm hotspot 7. 64-bit. 4 cores. how app run: java -jar -xmx4g prog.jar note: have seen this: tuning garbage collections low latency want understand why gc taking long kick in? it sounds have 1 of 2 issues going on: if have semi-long lived objects, moved young generation older (like on hotspot mark-compact generation .) is, they'll stop being reference counted collection , start being

here code find substring entered user in given string. bool find_str(char *str, char const *substr) { while(*str) { if(*str++ == *substr) { char const *a = substr; while((*str++ == *++a)); /*empty*/ if(*a == '\0') return true; } } return false; } // if match found, return true, else false int main(void) { printf("%d", find_str("abcdef", "cde")); /* return true in case */ printf("%d", find_str("abcde", "cde")); /* return false in case */ } as explained in comment, returns true whenever ends additional characters. if not, returns false. think there problem in increment/decrement operator. not find how? this because code decides stop on finding \0 after performing comparison *str++ == *++a this condition true when match happens @ end of string on null terminators, while loop happily proceed beyond end of both s

the pagination documentation suggests: the paginator must configured pagination-mapping specifying how configuration metadata mapped out of response payload. configured mapping must have objectclass of rkpaginator , should include attribute mappings currentpage, pagecount, perpage, , objectcount. example, given paginated resource loaded ‘/articles?page=1’ following json: { "pagination": { "per_page": 10, "total_pages": 25, "total_objects": 250 }, "articles": [ // array of articles ] } but if api doesn't provide me total_pages, gives me total_objects? can calculate total pages combination of per_page , total_objects. have feeling difference causing mappings not map. that should fine. paginator uses perpage , objectcount calculate pagecount (the project open source can verify , debug happens during mapping). if turn on trace logging should information what's happening during pagination mapping stage (like

when use yjp cpu-tracing profile on our own product, slow. the product runs in 16 core machine 8gb heap, , use grinder run small load test (e.g. 10 grinder threads) have 7~10 steps during profiling. have script start product profiler, start profiling (using controller api) , start grinder emulate user operations. when operations finish, script tells profiler stop profiling , save snapshot. during profiling, each step in grinder test, takes more 1 million ms finish. whole profiling takes more 10 hours 10 grinder threads, , each runs test 10 times. without profiler, finishes within 500 ms. so... besides problems product profiled, there else affects performance of cpu tracing process itself? last used yourkit (v7.5.11, pretty old, current version 12) had 2 cpu profiling settings: sampling , tracing, latter being faster , less accurate. since tracing supposed more accurate used myself , observed huge slowdown, in spite of statement slowdown "average". yet far l
