Hi.
I created a little script:
for currenturl in sys.argv:
pid = os.fork()
if pid == 0:
signal.alarm(10)
do_something() # placeholder for the download and print
routine

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...

Hi,
I need a little help here managing child processes in Python. I'm not so
skilled in system programming so I hope you can give me some good
suggestions.
I have a very CPU and memory intensive task that has to be repeated many
times (with different input parameters). So I've thought to write a
Python script that create a child process, wait for it to finish and
then starts again another child with different parameters.

Hi All,
I've written a few C functions in the version 1 format as well as some SPI
based backend bits and I'm curious as to how PG treats these items when used
within plpgsql.
The set of functions control external processes. One function is called with
various items governed by the db, does a fork and then execl to from the
child to start a new process. Whilst it's not posix i ignore the SIGCHLD
signal and let the parent process...

Hi
I was working on a project for school, that deals with processes and
windows.....here is a sample of the instruction:
You are to implement a game of Nim. Your implementation should consist of
three processes. Each process must have a visible window as it runs. The
main process is the manager. It should start the other two (player)
processes and manage the game. It is responsible for evaluating the game and
declaring a winner or a...

1. Create a TcpListener
2. Start a child Process
3. Kill the parent process
=> You can't bind to the port until you close the child process
Variant :
3. Terminate normally the parent process
=> The parent process stays as "Running" until the child process is
closed

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

I'm using the Python processing module. I've just run into a problem
though. Actually, it's a more general problem that isn't specific to
this module, but to the handling of Unix (Linux processes) in general.
Suppose for instance that for some reason or another, after forking
several child processes, the main process terminates or gets killed
(or segfaults or whatever) and the child processes are orphaned. Is
there any way to automatically...

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,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...

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...
