is there way create bash script run x hours? i'm setting cron job initiate script every night. script runs until condition met, exporting it's status holding variable keep track of 'where is' after each iteration. intention start-up process every night, run few hours, , stop, holding status until process starts next night. short of somehow collecting start time, , checking against current time in each iteration of loop, there easier way this? bash scripting not forte (i know enough things done , dangerous) , have not done before. appreciated. thanks. use gnu coreutils gnu coreutils contains actual timeout binary, invoked this: # timeout after 5 seconds when sleeping 30 /usr/bin/timeout 5s /bin/sleep 30 in case, you'd want specify hours instead of seconds, timeout in 2 hours use 2h instead of 5s . see timeout(1) or info coreutils 'timeout invocation' additional options. hacks , workarounds native timeouts or gnu timeout command be

is there way access containing/enclosing class during initialization (constructor logic) of nested owned class without needing reference passed constructor parameter? the reason don't want pass reference containing class constructor parameter nested owned class because virtually every single object in program need it, , feels sloppy passing in argument manually every time never change anyways. want simplify programming as possible other team members of mine using engine. i tried making method container class use when adding new objects take new instance parameter , set instance's "container" variable "this" (the container class), nested owned object's initialization code happens first defeats purpose (i want able access container during initialization, container variable needs set before, not after constructor code executed). any ways make happen? or doomed manually pass in reference container class every time make new nested owned object

in java there sane way have thread/task run continuously , end after specified run time (preferably without using several timers)? for instance, if have timertask , there doesn't seem way schedule task end after number of milliseconds or @ specific time timer class. sure, can schedule task repeat after number of milliseconds, if want end after 1 iteration? have run timer within scheduled task? i'm hoping more elegant answer that. the answer provided in this question work, not had in mind. essentially , i'm looking similar autoreset property on c#'s system.timers.timer class you can use executorservice , grab future , .cancel() after time want: final future<whatever> f = executor.submit(...); timeunit.seconds.sleep(xxx); f.cancel(true); or can have 2 services: 1 executes, uses scheduledexecutorservice cancellation. note: timertask depends on system time, use scheduledexecutorservice instead.

i trying think of scenario need more 1 instances of db connection. normally, db connection 1 singleton object used everything. what's reason might want create instance of same class. (i read somewhere.) trying understand this, 2 instances of db connections seem risky cause conflict when writing db. faster when reading? (maybe 1 reason?) maybe db connection not example. can give me other scenario if know anywhere creating more 1 instance of singleton class make sense. you may need more specific on local app/embedded db vs servers. but, if have application server (iis, apache etc...) talks database server (sql server, oracle etc...), want concurrency , multiple connections active @ time. want concurrency since it's server handling many concurrent requests , sql servers should able handle that. serializing database activity on server catastrophic. concerning db connections, db access technologies, offer connection pooling . open connection, work , close.

i've been compiling , linking opencv code past few days following command: g++ motion.cpp -o motion `pkg-config --cflags --libs opencv` but have added call pyrup() function: pyrup( in, out, size( 640,480 ) ); now when compile following linker error: motion.cpp:(.text+0x1385): undefined reference `cv::pyrup(cv::_inputarray const&, cv::_outputarray const&, cv::size_<int> const&, int)' collect2: ld returned 1 exit status what missing? there alternative function should using? thought linking in of opencv libraries. as understand pkg-config( ref ) loads config file here /usr/local/lib/pkgconfig/opencv.pc contains number of settings. you may have add specific lib contains pyrup on end of line libs: -l${libdir} -lopencv_core -lopencv_imgproc -lopencv_highgui -lopencv_ml -lopencv_video -lopencv_features2d -lopencv_calib3d -lopencv_objdetect -lopencv_contrib -lopencv_legacy -lopencv_flann the opencv.pc file may reside in different folder

this question related converting list of numbers list of strings appending strings. how convert source below : source = list (range (1,4)) into result below: result = ('a1', 'a2', 'a3') you can either use list comprehension : # in python 2, range() returns `list`. so, don't need wrap in list() # in python 3, however, range() returns iterator. need wrap # in `list()`. can choose accordingly. infer python 3 code. >>> source = list(range(1, 4)) >>> result = ['a' + str(v) v in source] >>> result ['a1', 'a2', 'a3'] or map() lambda : >>> map(lambda x: 'a' + str(x), source) ['a1', 'a2', 'a3']
