My application starts up a number of processes for various purposes using:
self.popen = popen2.Popen3("/usr/local/bin/python -O "myscript.py")
and then shuts them down when appropriate with
os.kill(self.popen.pid, signal.SIGTERM)
Everything works fine on MacOSX. However, I'm doing a port to Solaris (so I
can run it on my web site) and find that the child processes are not
stopping! Solaris is creating TWO new processes: one for the SHELL...

All,
I've got a process that creates some children and want to be alerted
when they die. To do this, the SIGCHLD signal is registered in the
process using sigaction to jump to a subprogram as soon as it's
received.
The problem comes when many children exit at the same time and their
father seems to miss some of them. This happens quite often, but not
always.

I'm doing a c# asp.net web application. It create a process "A" to
excute an .exe file. This exe file is compiled from c++. In this exe
file it will create another new process "B" to excute another .exe
file. (This one is VB, but I think this doesn't matter). What I want
to do is when I kill the first process "A" from c#(usill kill()
function) I want to kill the child process "B" at the same time.
If all is in c++ maybe I can figure it out...

i'm using .NET 2.0, and i've made a lot of tests
i've come to the conclusion that TCP servers (tcplistener), started by
a father process, are somewhat inherited by child processes if using
UseShellExecute = false
why is that ?
try it ! even if the TcpListener is started *after* the
childProcess.Start, the TCP server is still registered in netstat -ao
and connectable with telnet, even if the father process stopped (or

Dll written in VB.NET 2003 to start a command remotely.
You can :
- launch the command and wait until it's finished. (Ex. 1)
- launch the command providing a timeout in seconds, it will wait until
it's finished. If the command didn't terminate within the timeout, the
command is killed. (Ex. 2)
- launch the command and continue your processing after the command has
been started remotely (Ex. 3).

This may be a silly question but is possible for os.wait() to lose track
of child processes? I'm running Python 2.4.4 on Linux kernel 2.6.20
(i686), gcc4.1.1, and glibc-2.5.
Here's what happened in my situation. I first created a few child
processes with Popen, then in a while(True) loop wait on any of the
child process to exit, then restart a child process:
import os
from subprocess import Popen

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
