sorry not english. new theme me (i mean speak first time using english :) can make mistakes). so problem. i have, example 3 variants. probabilities : 0.5, 0.2, 0.3 example. how can choose variant choose right now? think can this way: create interval [0; 1]. separate smaller intervals (3 in example). [0; 0.5), [0.5, 0.7), [0.7, 1]. generate random number 0 1 (float, double) detect interval number belongs to for example 0.3 generated, 1st interval, first variant. is right approach? how code using javascript or @ least show pseudo code. p.s.: have dynamic amount of variants every time. thank you. it right approach , can working this: var rand = math.random(); if (rand < 0.5) { // first variant } else if (rand < 0.7) { // second variant } else { // third variant } you don't need completly specify intervals in conditions because math.random() generates real numbers interval [0,1]. for dynamic amount of variants can create arra...

when create delegate in c#, point function definite signature (parameter set), asks specify identifier each type. public delegate void mydelegate(int x, int y); if try write prototype declaration as: public delegate void mydelegate(int, int) it shows compile time error saying identifier expected . but according me, when specifying prototype method, why compiler needs identifier distinguish between 2 methods different signature: public delegate void firstdelegate(int); and public delegate void seconddelegate(int, int); are sufficient , clear declaration distinguish between them. think so i think people got me?? it can make difference @ point of invocation. example: using system; class test { delegate void foo(int x, int y); static void main() { foo foo = (x, y) => console.writeline("x={0}, y={1}", x, y); foo(x: 5, y: 10); foo(y: 10, x: 5); } } the output x=5, y=10 both lines, because argum...

okay, want user able click on particular area of video , x happens, otherwise nothing happens, pure javascript, not jquery... i've got: document.getelementbyid('videoele').addeventlistener('click',handleclick,false); function handleclick() { if(video.currenttime > 24.5 && video.currenttime < 29) { console.log("good timed click: " + video.currenttime); } else { console.log(video.currenttime); } } there's things intend change src of video if click in right time , right position, can't find on positional clicking on html5 video element. possible yet? i using customised buttons, not should make difference. thanks in advance! try using this: videoelement = document.getelementbyid("videoele"); videoelement.addeventlistener("mousedown", handleclick, false); handleclick = function(e) { if(videoelement.currenttime > 24.5 && videoelement.currenttime < 29)...

so have classical hanoi problem, im getting recursion thing, , doozie! functioning, don't understand how be! i've understood it, n, print "from + " going " + thru", happen each time n approaches 1. 1 think @ n=1, code stop, , yet printouts of "thru + " going " + to" (last printout). if n=1 terminating condition, how can possibly last part of code "for free?". i expected code @ least execute last printout on every iteration, no! also, examples of include 2 recursive calls, works fine one! hell going on? how code execute, step step? have misunderstood basic fact recursive methods? (compiled on eclipse compiler). public static void hanoi(char from, char to, char thru, int n) { if (n==1) { system.out.println(from + " going " + to); } else { system.out.println (from + " going " + thru); hanoi(from, to, thru, n-1); system.out.println (thru + " going " + to); } } have misund...

i'm trying program needs catch full path of files being used (anywhere in system) straight example. opened file called "notify.py" whichis in /home/miguel/dropbox/prog/python/notify/ directory. when call ps aux in linux shell, process line corresponding file's process is miguel 11798 0.7 0.4 512320 34176 pts/2 sl 22:41 0:06 gedit notify.py which doesn't path of file opened! wanted (and have been looking hours, using ps, lsof or python's psutil) way full path of file corresponding process, is, i'd like, process, directory line referenced above. thanks answers you might try readlink(2) file /proc/<pid>/exe , should want: $ ls -l /proc/$$/exe lrwxrwxrwx 1 aw aw 0 apr 7 00:02 /proc/11700/exe -> /bin/zsh $ but note not overly portable. should work on linux , @ least freebsd, might fail on other unices. that's reason why e.g. sshd want's called full path, sufficient take $0 (or argv[0] or whate...

i writing python program imports 1000s of data point in blocks of 10 points @ time. each block of 10 data points maximum set found, program loops next 10 data points , continues. of works fine, need build array hold maximum data point created once per loop, can plot them later. how can create array within loop, here have: for count in range(self.files/self.block_length): rss = scipy.fromfile(self.hfile2, dtype=self.datatype, count=self.block_length) maxrss = np.max(rss)#takes greatest value in array of size defined block_length here maxrss works great save file or print screen, program loops; however, @ end of loop holds last value , need hold of max values found not sure if answer want... assuming for loop breaks 1000s of points correctly chunks of 10 (which don't see in example), create array within array, need make maxrss list , append things it: maxrss = [] count in range(self.files/self.block_length): rss = scipy.fromfile(self.hfile2, dtype=...
