there java program read files folder, processing , write output files in folder. ran 4 hours , produced few files failed after throwing following error: "too many files" then modified program close (bufferreader , bufferwriter) , started process again. time process failed after starting throwing following error: java.io.filenotfoundexception: <file> (too many open files) then tried running lsof , searched process having no of open files. realized networkmanager. not sure whether should kill process or not. restarted machine. after when ran java program, still got same error. in worst case might possible code still having leaks in terms of not closing everything, still failing after starting process. have feeling lying in system previous run. if start same process in other machine, runs hours before failing. you cannot retain resource between runs of program, if wanted to. leave system without enough resources in theory, though unlikely, restarting

how can run application , leave instead of waiting when ended? example : /var/tmp/runme.sh & following code working waits forever when google chrome exit. how can run google chrome let script exit? import subprocess import sys import time line = sys.argv[1] print line def kill_chrome(): subprocess.call(['taskkill', '/im', 'chrome.exe', '/f']) def run_chrome(): subprocess.call(['c:/program files (x86)/google/chrome/application/chrome.exe', '--kiosk']) def run_java(): subprocess.call(['java', '-cp', 'c:/python27/pdfbox-app-2.0.0-rc3.jar;c:/python27/jprint.jar', 'jprint']) try: if line.startswith("myjava:website"): print "google chrome - idle" run_chrome() elif line.startswith("myjava:a4"): print "printing - java" run_java() elif line.startswith("myjava:kill"): print "killer" kill_chrome() except

i have bunch of bytes written line line file each line can have varying number of bytes , need read them line line wondering how in efficient way using nio or apache commons io? trying see if there way api can take care of allocation , deallocation of buffers since dont know length of bytes in each line. can read string , .getbytes().length() sounds bit awkward. if file consists of lines, can read millions of lines second bufferedreader.readline(). don't need else. in case nio doesn't support reading lines in way shape or form.

in highcharts show percentage along pie_charts , legend can customized this: legend: {labelformat: '{name} : {y} ({percentage}%)'} but in chartkicks can't find how this? if @ documentation specified on chartkick gem homepage, says: you can pass options directly charting library with: <%= line_chart data, library: {backgroundcolor: "#eee"} %> so in scenario, should try like: <%= pie_chart data, library: {legend: {labelformat: '{name} : {y} ({percentage}%)'}} %>

i have looked @ spring-cloud-config client without spring boot , many others , have not found convincing answer. here goes again: question : possible, in spring app, use spring cloud config server/client without automagic configuration of spring boot? using spring boot requirement using these frameworks? if is: is there documentation describes needs done in order enable spring cloud config server/client without spring boot? is there sample project describes needs done in order enable spring cloud config server/client without spring boot?? i'm not aware of documentation or sample project. doing in our projects. you need include configuration server uri property source, assuming using propertysourcesplaceholderconfigurer: <bean class="org.springframework.context.support.propertysourcesplaceholderconfigurer" id="propertyplaceholder"> <property name="locations"> <list> <value>http:/

i have started working jointjs. have not seen example/tutorial on website mentioning creating of link again once deleted. example on link. http://jointjs.com/demos/org i wonder if possible create link again between 2 members once deleted. i tried code in function function (x, y, rank, background, textcolor) : '.rank': { text: rank, fill: textcolor, 'word-spacing': '-5px', 'letter-spacing': 0, magnet: true, pointerevents:'none' } but not working. i not sure if member type has ports. if yes need add ports recreate links once rendered. if @ source code, links created during render if refresh page or run code again links come back.

there function can randomize spilt data trainingrdd, validationrdd, testrdd = rdd.randomsplit([6, 2, 2], seed=0l) i'm curious if there way generate data same partition ( train 60 / valid 20 / test 20 ) without randommize ( let's use current data split first 60 = train, next 20 =valid , last 20 test data) is there possible way split data similar way split not randomize? the basic issue here unless have index column in data, there no concept of "first rows" , "next rows" in rdd, it's unordered set. if have integer index column this: train = rdd.filter(lambda r: r['index'] % 5 <= 3) validation = rdd.filter(lambda r: r['index'] % 5 == 4) test = rdd.filter(lambda r: r['index'] % 5 == 5)

part of code generates string, suppose used function generated chuck in voxeljs. an example string "(y == 1)? 1 : 0" which need added function this, eg. "function(x, y, z){return (y == 1)? 1 : 0}" i thought using eval change string needed code, this: gtest = function(x, y, z){return eval(generationstring) }; but misunderstood how eval used, , realized needed try else. if @ gtest in javascript console says it's structure function (x, y, z){return eval(generationstring) } when want function (x, y, z){return return (y == 1)? 1 : 0}} . attempting pass code containting eval causes voxeljs crash/freeze when tries generate new chunks. how can convert string javascript code code in function in way want? i realize might hard understand question, sorry that, i'm not sure how describe other way. i found answer literally 30 seconds after posting this, use function() constructor. given string describing javascript function, convert javasc

consider c1 base class of c3. below code works perfectly. c1 obj1=new c3(); c3 obj2=(c3)obj1; but, there classcastexception in below one c1 obj1=new c1(); c3 obj3=(c3)obj1; what have missed? i think what's happening creating obj1 instance of c1, , trying cast class further down inheritance chain c1. in first example, c1 base type of c3 , can create instance of c3 type c1..that's fine. c3 child of c1 , inherits properties , methods. in 2nd example, however, creating instance of c1 type of c1. trying cast child. child class may have additional properties , methods parent doesn't have. to summarise, child can of parent type , cast it, however, parent cannot child , cannot cast such. if need further clarification, let me know.

i'm trying implement peer-to-peer chat application using udp , wondering how scale program multiple users. as understand it, udp needs 1 socket send , receive data using recvfrom , sendto functions. using data address fields passed these functions, can determine user i'm communicating with. i wondering if create multiple udp sockets on same port each peer i'm talking to. way, if data comes peer x, data goes udp port , gets passed appropriate socket 'bound' x's address. is there anyway while still using udp? yes, can specify so_reuseaddr (so_reuseport on linux) before binding udp socket ( all sockets including first), , connect each socket appropriate target, it's not necessary. dispatch each message arriving on single socket according source-address.
