intervals

Given this code: bob = setInterval(function, 1000); clearInterval(bob); Is there now a way to know if that interval has been cleared? Currently, I keep track of this myself, by unsetting ' bob ', but I'm curious if my extra line of code is unnecessary: clearInterval(bob); bob = null; if (!bob) itIsCleared(); Thanks! Rich The return value of setInterval is just a unique id you use to pass back to clearInterval . It's not a structured object with any additional information, nor does it get set to null when you call clearTimeout . bob only contains an id of the interval used to clear it. When you

I have the following sorted python list, although multiple values can occur: [0.0943200769115388, 0.17380131294164516, 0.4063245853719435, 0.45796523225774904, 0.5040225609708342, 0.5229351852840304, 0.6145136350368882, 0.6220712583558284, 0.7190096076050408, 0.8486436998476048, 0.8957381707345986, 0.9774325873910711, 0.9832076130275351, 0.985386554764682, 1.0] Now, I want to know the index in the array where a particular value may fall: For example, a value of 0.25 would fall in index 2 because it is between 0.173 and 0.40. I guess I can go through the list and do this in a for loop but I was

I want to merge two data frames. Both of them have a begin date and an end date. If the given intervals are overlapping, I want to split the resulting rows in non overlapping intevals. Please see this example: a id beg_a end_a prop_a 1 2000-01-01 2002-12-31 A 2 2000-01-01 2000-02-15 B 2 2000-04-01 2000-04-15 A 2 2002-01-01 2002-12-31 B 3 2000-01-01 2000-06-15 A b id beg_b end_b prop_b 1 1999-06-01 2000-05-15 D 1 2003-01-15 2003-01-31 D 2 1999-01-01 2003-01-15 D 3 2000-07-01 2001-08-01 E merged id beg_a end_a prop_a beg_b end_b prop_b overallBeg overallEnd 1 <NA> <NA> <NA> 1999-06-01 2000-05-15

I found a solution to run interval in javascript immidiately, not waiting for a first "timeout" setInterval(function hello() { console.log('world'); return hello; }(), 2500); But problem is this solution isn't working is construction like this (function () { window.Banner = { doMagic: function () { setInterval(function magic() { console.log('magic'); return magic; }, 2500); } } })(); Banner.doMagic(); I've tried to return Banner method, to name it and return and no success. Point is what in real construction is much more complex, so i can't just rewrite it to "return setTimeout" solution, as

I am trying to set a repeating alarm that will will download a file every minute but only between 8:00 and 22:00. I feel like I'm really close but I can't see the error I'm making. Currently the broadcast receiver is not activating. If set the repeating alarm manually to alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis()+10000, 60000,pendingIntent); it works fine. Any guidance would be much appreciated. protected void scheduleNextUpdate() { Intent intent = new Intent("TEST"); PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, intent, PendingIntent.FLAG

Quick question about the $interval service in angular. Looking at the docs ( $interval ) they warn you to manually cancel intervals, but you have the option of providing a count parameter upon initialization. Once the timer has "ticked" past the allotted count does it cancel itself or simply stop calling the function and live on in the background? Renan Ferreira TL;DR; After the count, the interval is cleared. As the same documentation says, it is recommended that you cancel the $interval when the scope of your controller is detroyed. Something like: var t = $interval(function(){ ... }, 1000);

Suppose I have list of time interval like a = [datetime.time(0,0),datetime.time(8,0)] Now I Have lacs of intervals in list like given below. b = [[datetime.time(0,0),datetime.time(8,0)], [datetime.time(0,0),datetime.time(10,0)], [datetime.time(0,0),datetime.time(23,59,59)], [datetime.time(15,0),datetime.time(9,0)], [datetime.time(9,0),datetime.time(15,0)]] We have to filter list b with intervals containing interval a. like in example result will be. b = [[datetime.time(0,0),datetime.time(8,0)], [datetime.time(0,0),datetime.time(10,0)], [datetime.time(0,0),datetime.time(23,59,59)], [datetime
