so having issue alarmmanager. trying run code every 2 minutes, works okay while phone awake, not when device goes sleep - during sleep, intervals 5 minutes apart. since desired interval 2 minutes, 250% off target interval, specific application not acceptable. i aware of changes in api 19, , have followed suggestions re-schedule alarm using setexact() within broadcastreceiver. code below: the code used trigger broadcastreceiver: intent intent = new intent(this, alarmreceiver.class); final pendingintent pendingintent = pendingintent.getbroadcast(this, 0, intent, 0); malarmmanager = (alarmmanager) this.getsystemservice(context.alarm_service); malarmmanager.setexact(alarmmanager.elapsed_realtime_wakeup, systemclock.elapsedrealtime() + 3000, pendingintent); and code in broadcastreceiver re-schedules alarm: @override public void onreceive(context context, intent intent) { toast.maketext(context, "alarmservice triggered.", toast.length_short).sh...

i want fill random bytes files recursivelly root directory. files, folders left untoutched i don´t want delete files, fill them random bytes in research, fill command single file like: dd if=/dev/random of=target-files bs=1m and find files recursivelly should use: find . -name "* .*" my questions are: is possible achieve goal joining 2 commands? (pipe them? how?) is there easier way achieve same results? thanks ;-) you may try pipe find result while loop, , dd /dev/udrandom each files. $ find myfolder -type f |while read fd; dd if=/dev/urandom of=$fd bs=1m count=1;done if want retain file size, may calculation on finding 1k block count , pass args in dd. $ find myfolder -type f|while read fd; fsiz=`stat -c %s $fd`; cnt=`expr $fsiz / 1024`;dd if=/dev/urandom of=$fd bs=1k count=$cnt;done

i have 1 matrix of size 12 , array of size 4 given below: a=[23,45,1;4,6,7;9,5,0;145,65,32]; b=[3,2,4,6]; i want new array c c=[23,45,1,4,6,7,9,5,0,145,65,32,3,2,4,6]; i did following : a=[23,45,1;4,6,7;9,5,0;145,65,32]; b=[3,2,4,6]; a=reshape(a',12,1); b=b(:); c=[a b]; but giving error : error using ==> horzcat cat arguments dimensions not consistent. a = a(:); b = b(:); c = [a; b]; note difference between [a b] or [a, b] , [a; b].

i thought web socket guarantees delivery of data built on top of tcp reliable. reading java web socket api documentation on link https://docs.oracle.com/javaee/7/api/javax/websocket/remoteendpoint.html says there no guarantee of successful delivery of web socket message peer, if action of sending message causes error known container, api throws it. shouldn't tcp gurantee message delivery? reliable != guaranteed. reliable means you'll notified if there failure (or success) - if end users unplugs lan cable, tcp can't 'guarantee delivery.'

i have 2 feature files in project 1 step common in these 2 files need call 2 different step definition function depending upon file on steps written. do have configuration that? so if understand correctly, have 1 line in cucumber needs execute 2 different methods? far know not possible. cucumber keep on telling there multiple methods same name. - title. what explanation different. have 2 feature files common step. 1 feature file getting steps classfile , other feature file getting steps classfile b? in case, can best extend public classes can use code class file in feature file.

problem described in image giving error in text. i don't know why question being downvoted, because it's legitimate , common mistake beginner users make when using git. you accidentally created branch br-02 branch br-01 . 1 solution create branch using correct base, , cherry-pick commits have made on br-02 onto correct branch. git checkout bs-00 # switch correct branch git checkout -b br-03 # create correct branch using bs-00 base git cherry-pick <sha-1> # cherry-pick commit br-02 here <sha-1> hash of commit on branch br-02 wish keep. can find out value switching br-02 , typing git log terminal. note merging commit made on branch br-02 branch br-03 , there might conflicts. finally, can delete bad branch br-02 since don't need anymore: git branch -d br-02 # delete wrong branch br-02 locally git push origin :br-02 # delete wrong branch br-02 on remote

is there difference between declaring datasource in meta-if/context.xml file , spring bean using jndi lookup (approach 1), or declaring datasource directly via spring (approach 2) : @bean(destroymethod = "close") datasource datasource(environment env) { hikariconfig datasourceconfig = new hikariconfig(); datasourceconfig.setdriverclassname(env.getrequiredproperty(property_name_db_driver_class)); datasourceconfig.setjdbcurl(env.getrequiredproperty(property_name_db_url)); datasourceconfig.setusername(env.getrequiredproperty(property_name_db_user)); datasourceconfig.setpassword(env.getrequiredproperty(property_name_db_password)); return new hikaridatasource(datasourceconfig); } i think second approach better because not tied specefic server, means if use first approach , 1 day migrate server must adapt strategie of context file in second server (not true ?). thanks some points first approach (jndi lookup of datasource defined in con...
