this question has answer here: why subprocess.popen not waiting until child process terminates? 3 answers i have python programme below import os import subprocess m in range(0,10): os.chdir("c:/") run="my command%d"%m subprocess.popen(run).wait() where 'my command' used launch programme. although have wait() after popen, turns out 10 programmes still run simultaneously, not expected. how settle issue? two options: use subprocess.check_call() (which should run sequentially) use popen.communicate() ( https://docs.python.org/2/library/subprocess.html#subprocess.popen.communicate ) stdout , stderr set subprocess.pipe see if stdout , stderr indeed sequentially generated also, datetime.datetime.now() gives microsecond, can see time granularity higher 1s.

i'm transitioning matlab fortran , encountering sorts of weird behaviors i'd never expect matlab. here's 1 that's got me puzzled: program pruebanormal double precision :: g01eaf, x, y character :: t*1 integer :: iffail iffail = 0 t = 'l' x = 0.0 y = g01eaf('l',0.0,iffail) write(*,*) 'y = ',y end program pruebanormal i have simple program in i'm trying find pdf @ x=0 of standard n(0,1) variable (should 0.5). g01eaf() nag library function me. i'm using gfortran compile. leaving rest of program unchanged, depending on how write arguments in g01eaf() , different answers: a) g01eaf(t,x,iffail) b) g01eaf(t,0.0,iffail) c) g01eaf(t,x,0) now, under matlab, same (correct) answer either way: y = 0.500000. under fortran, however, get: a) y = 0.500000 b) y = 1.000000 c) program received signal sigsegv: segmentation fault - invalid memory reference. backtrace error: #0 0xb766c163 #1 0xb766c800 #2 0xb77763ff #3 0x80498...

i wrote code , found didn't work expected. for example, following return false or throw exception, undefined variable: a : if ($a = 12 && $a == 12) { return true; } else { return false; } i fixed wrapping assignment in parentheses: if (($a = 12) && $a == 12) { return true; } else { return false; } it lucky guess. i'm wondering why parentheses needed , haven't found explains why. that because of operator precedence . assignment operator = has lower precedence && , without parenthesis doing following. if ($a = (12 && $a == 12)) observe second $a not yet defined before assignment happens, because has evaluated before assignment can happen.

here's deal, i'm trying segment capsicum @ lower centre of image using matlab. tried intensity level slicing problem intensity levels close. tried stretching histogram , doing no luck. can me? https://www.google.co.in/search?q=grayscale+image+matlab&source=lnms&tbm=isch&sa=x&ei=0_ahu6hll9ixuatirikadg&sqi=2&ved=0cayq_auoaq&biw=1366&bih=622#q=+matlab+flower+grayscale&tbm=isch&facrc= &imgdii= &imgrc=awrqu-vbisji3m%253a%3bfy0fngztpyzszm%3bhttp%253a%252f%252fwww.cs.tut.fi%252f~foi%252fgcf-bm3d%252fimages%252fpeppers256_est_s15.png%3bhttp%253a%252f%252fwww.cs.tut.fi%252f~foi%252fgcf-bm3d%252f%3b256%3b256

i need method calculate outdegree of each vertex of dag check whether leaf or not.i m using java boolean adjancency matrix representation sum along row. in adjacency matrix, there 1 @ position ( i , j ) if there edge vertex i vertex j . therefore, outgoing edges of vertex i in row i . sum of row i therefore gives outdegree of vertex i . for transposed adjacency matrix, sum along columns. like david says, if you're interested in whether outdegree 0 or not can save work stopping summation if find 1.

i have advertisements , scripts run on forum, , page continues load forever because scripts aren't loading on time (i.e. facebook, adsense). have javascript automatically stop page continuous load after, say, 10 seconds? how can sure page loaded in 10 seconds? if user has poor internet connection/speed? what suggest put javascript of advertisements , tracking (anaylytics) etc @ end of page. or if can use jquery put in ready function, when document/page ready, start calling js functions advertisements , all. $( document ).ready(function() { // code goes here });

i using phpexcel read date cells in excel file have values 'mar-13' returning integer values '41791'. please, need make sure date reads in correctly? excel stores dates serialized timestamps (number of days since 1/1/1900), can convert unix timestamp , format standard php date functions $unix_timestamp = ($cell_value - 25569) * 86400; $phpdate = date("m-d-y", $unix_timestamp);

i want implement cache in java. below requirement want cache 1 table on server startup.onece cached,i fetch data cache give key , return value associated key suppose if key not present call method , can put data in cache key , return me value. googled , found google guava cache , implement requirement 1 option if possile want know other cache frameworks can choose option that. please note using jsp,servelet jdbc means not using spring,hibernate or framework in application. appriciated thanks in advance find example of java caching system (jcs).i think solve problem. http://commons.apache.org/proper/commons-jcs/usingjcsbasicweb.html

i have generic callback function notify listeners when value has changed: public func<t, t, task> valuechangedasync { get; set; } where first t should old value , second t should new value. i use callback this: await valuechangedasync(old, newvalue); can make users of function aware of t old value , new value? when using callback gets implemented default: private task valuechangedasync(string s, string s1) { throw new notimplementedexception(); } i "s" named "oldvalue" , "s1" named "newvalue" or such. you events , custom delegate type, delegate type documentation can indicate old value , new value parts. example: // want non-void return type, we're not following event conventions // anyway... might have 3 parameters... public delegate task valuechangedhandler<t>(object source, t oldvalue, t newvalue); then: public event valuechangedhandler<string> valuechanged; invoke as: valuechanged...
