I need to do a touch of several files in a directory in reverse alphabetical order, with a 1 second delay. These files have spaces in their names. I've tried this: ls | sort -r | tr '\012' '\000' | xargs -0 touch and this: #!/bin/bash for i in $(ls -r); do touch "$i" sleep 1 done but the first makes it too quick and doesn...

Detect OS Sleep and Wake Up events in Java
Is there a way for a Java program to detect when the operating system is about to go to sleep, or failing that, at least detecting a wake up?

How accurate is Thread.Sleep(TimeSpan)?
I've come across a unit test that is failing intermittently because the time elapsed isn't what I expect it to be. An example of what this test looks like is: Stopwatch stopwatch = new Stopwatch(); stopwatch.Start(); TimeSpan oneSecond = new TimeSpan(0, 0, 1); for(int i=0; i<3; i++) { Thread.Sleep(oneSecond); } stopwatch.Stop();...

I wrote a plug-in for the jetbrains tool teamcity. It is pretty much just a server listener that listens for a build being triggered and outputs some text files with information about different builds like what triggered it, how many changes there where ect ect.

Programs run in 2 seconds on my machine but 15 seconds on others.
I have two programs written in C++ that use Winsock. They both accept TCP connections and one sends data the other receives data. They are compiled in Visual Studio 2008. I also have a program written in C# that connects to both C++ programs and forwards the packets it receives from one and sends them to the other. In the process it coun...

AccessViolationException while executing Threading.Thread.Sleep
We have developed an application that has intensive thread use (+-50 threads) in Vb.Net. From time to time we get an AccessViolationException at a random thread while it is doing a Thread.Sleep(). As far as we know we're no executing unsafe code as all our code is managed. We're using DevExpress controls but we don't know if they have u...

SwitchToThread vs Sleep(1)
I'm wondering what's the actual difference between calling Thread.Sleep(1) and calling SwitchToThread (if we ignore that it's currently not exposed by the BCL). Joe Duffy mentions in his post that: "The kernel32!SwitchToThread API doesn't exhibit the problems that Sleep(0) and Sleep(1) do." (regarding the scheduler's behavior) Why...
Sleep() becomes less accurate after replacing a PC? (C++)
I have a program that was built in C++ (MFC, Visual Studio 6.0) several years ago and has been running on a certain Windows machine for quite some time (more than 5 years). The PC was replaced a month ago (the old one died), and since then the program's timing behavior changed. I need help understanding why. The main functionality of th...

Currently cards are dealt and appear on the UI instantaneously. I want to have to program pause for a moment after dealing a card before it deals the next. When a game is started the following code...
Timer & TimerTask versus Thread + sleep in Java
I found similar questions asked here but there weren't answers to my satisfaction. So rephrasing the question again- I have a task that needs to be done on a periodic basis (say 1 minute intervals). What is advantage of using Timertask & Timer to do this as opposed to creating a new thread that has a infinite loop with sleep? Code snip...
