sleep

Why does a sleep thread need a try catch to catch Interrupted Exception? Why does a sleep even emit an Interrupted Exception error? This are the two questions I really wanna find out about in java programming I've been searching through google and i've still haven't found a clear explanation is to why this two things happen. 1.- Because a Thread cant complete its normal execution if you Interrupt it, and you need to catch that in order to be prepared to do something. 2.- Because a thread waiting is different from an interrupted thread, a thread waiting can be resumed, but an interrupted thread

I have a lengthy number-crunching process which takes advantage of quite abit of OpenGL off-screen rendering. It all works well but when I leave it to work on its own while I go make a sandwich I would usually find that it crashed while I was away. I was able to determine that the crash occurs very close to the moment The laptop I'm using decides to turn off the screen to conserve energy. The crash itself is well inside the NVIDIA dlls so there is no hope to know what's going on. The obvious solution is to turn off the power management feature that turns the screen and video card off but I'm

I saw that there is a question about pthread sleep linux However, when I looked up man page on my linux machine, I see the following. SYNOPSIS #include unsigned int sleep(unsigned int seconds); DESCRIPTION sleep() makes the current process sleep until seconds seconds have elapsed or a signal arrives which is not ignored. So my question is that I would like to know which man page I should follow to put the thread sleep. In addition, if both are true, how can I control that? I can probably write some code to test it but I want to make sure to hear some feedback from other people as well. Thank

There's an instrument on my LAN that sends a UDP data packet every 5-10 ms. In my application, I have a reader thread that allocates a socket with a large buffer when it starts, then enters an infinite loop to read the accumulated packets, parse them, write them to a spooler, then sleep for half a second ( time.sleep(0.500) ). I have several lazy consumers for the data, most of which do archiving or generate passive statistics. But one consumer (for display) needs up-to-the-moment data, and needs to wake the sleeping reader (to read the socket) before querying the spooler. What is the best way

How to make a non-blocking sleep in javascript/jquery? Lucas At the risk of stealing the answer from your commentors, use setTimeout() . For example: var aWhile = 5000; // 5 seconds var doSomethingAfterAWhile = function() { // do something } setTimeout( doSomethingAfterAWhile, aWhile ); 来源： https://stackoverflow.com/questions/7729382/how-to-make-a-non-blocking-sleep-in-javascript-jquery

I notice that NetBeans is warning me about using Thread.sleep() in a while loop in my Java code, so I've done some research on the subject. It seems primarily the issue is one of performance, where your while condition may become true while the counter is still sleeping, thus wasting wall-clock time as you wait for the next iteration. This all makes perfect sense. My application has a need to contact a remote system and periodically poll for the state of an operation, waiting until the operation is complete before sending the next request. At the moment the code logically does this: String

Does pgsql have a waitfor statement like t-sql . Thanks. Does pgsql have a waitfor statement like t-sql. Yes, pg_sleep : pg=> SELECT pg_sleep(10); pg_sleep ---------- (1 row) You could call the pg_sleep function with the PERFORM statement since we don't care about returning values:
