my ultimate goal run python script (the code need call subprocess ) without terminal. i tried python launcher on mac. code works correctly when "run in terminal window" checked. (notice shell=false default here.) however, won't run subprocess correctly when uncheck option. i tried run in mac os automator ( run shell script ) — negative too. here small sample code. import subprocess open("record","w") f: subprocess.call(["which","ipython"], stdout = f) # line fails subprocess.call(["open","."]) # line works if run terminal, creates record file, shows ipython path. when run automator or python launcher without terminal window, creates empty file.

hello new here , taking javascript course @ university software development degree. running issue in rock paper scissors lizard spock final project. professor has given qunit tests can check our code not @ understanding how errors show me whats wrong don't understand how code work. far have created objects , gave them properties , methods. created matrix capture , retain variations of win conditions. don't understand how create final method need: getwinner. in our rubric states following: "method evaluate won game. should update wins, losses, , rate of each player. should set "winner" property name of winning player." here game.js file working on. @ bottom stumped how start getwinner function. have started not responding unit tests. can post code if need well. other file object. var game = function(){ this.running = false; this.name = "rpsls"; this.players = []; this.addplayer = function(name){ var player = new player(name);

i using pexpect login remote devices query metrics. the output of command large (about 15k bytes) , need extract many metrics output. use big pattern string "key1:([0-9a-za-z]*).*key2:([0-9a-za-z]*).*key3......" to match metrics. when pattern long, expect block , never terminate. i've set maxread 20k doesn't work. have ideas on how resolve issue? add code snippet: session.sendline(command_info["text"]) ret = session.expect([cmd_prompt, pexpect.eof, pexpect.timeout]) if ret == 1: logger.error("eof error.") return if ret == 2: logger.error("timeout") return result = re.match(getexpectedgroupstr(command_info, logger), session.before, re.s) if use big pattern string instead of cmd_prompt, session.expect hang , never terminate if timeout reached.

i have class has field gets set through spring bean , annotated @autowired so: public class foo { .... @autowired private bar bar; .... } i want setup junit test tests functionality @ point create foo object. not in control of when foo object generated. easiest way mock object anytime foo gets instantiated, object populated mocked item? using 3rd party library mock bar object nicely, prefer of in java test class without using xml files. everything have found online seems either involve creating xml file or mocking specific instance of class. thank help! i following: public class test { private bar mockedbar = createbar(); // somehow set 'mockedbar' foo object // created contains mockedbar } i have written uch test of jmockit , please read might you. you need create object overriding required methods. then use deencapsulation.setfield(fixture,new bar(){ //@override methods }); fixture object in want bar

i have structure in following format: a.l1.data = <1000x3 double> a.l2.data = <1000x3 double> a.l3.data = <1000x3 double> i obtain mean of first column of fields, i.e. 1 vector of 1000 rows mean of l1, l2 , l3. i have tried using structfun following code: foo = structfun(@(x) mean(x.data(:,1)), a, 'uniformoutput', false) however, gives me mean (single value) of each first column rather mean of fields. if do: foo = structfun(@(x) mean(x.data), a, 'uniformoutput', false) i obtain mean of each column each field. how should modify code? you can access data of struct struct2array . get struct firstcolumnsofdata fields l1 l2 l3 first columns of data : firstcolumnsofdata = structfun(@(x) x.data(:,1), a, 'uniformoutput', false) get mean of each element of l1 l2 l3 : ml123 = mean(struct2array(firstcolumnsofdata')) % transpose not mean of each field

is recommended write code in uppercase ? like: $variable = "johndoe"; require_once 'class.username.php'; $_username = new username(); $_username->add($variable); thanks. you free use whatever case want. historically there have been several conventions. preferred uppercase, lowercase, , yet preferred mixed case. used depended on how wrote html, , background came (some programming languages encouraged/required use uppercase, instance, , because php not picky case use easy continue using knew). now-a-days there couple conventions. following see when reading other people's code: most people use lowercase variable , function names: $name = "some name"; function age(person $person) { return $person->age; } as names contain more 1 word there tends 2 camps: prefer camelcase, , prefer under_score: $personname = "some name"; function getage(person $person) { return $person->age; } // or... $person_name =

basically, want achieve follows; i want able compare pointer-pointer structure block in memory without having iterate through of values dynamically. working api-hook, crucial use little "for loop iteration" possible, better-yet, use none. basically, assume have structure typedef struct mystruct { ushort age; pchar username; } _mystruct, *__mystruct; then initialize so __mystruct *pointer; zeromemory(&pointer, null); now assume structure filled group of values in each variable. let's have defined number 'x', , given 'y' given index in pointer structure. for (int y = 0; y < sizeofstructure; ++y) if (x == pointer[y]->age) // do_something(); so, in case, 'y' iteration variable for-loop, how can along line of: if (memcmp(&pointer, x) == 0) // do_something(); so in case not iterating structure, , instead comparing of elements in memory @ once? for-loop operation with-in critical_section either way still
