problems with popen (linux7.3 python2.2.2)

When I use:
os.popen('ssh -l root@something tomcat4 stop')
I find the command always hangs. The 'something' host contains the correct
key in the authorized_host s file and works ok on the command prompt. I've
tried os.system() but this also hangs. I notice that the 'tomcat4 stop' is
being executed but when I do a 'ps -ef' I notice the popen process is still
alive. I've also noticed this command sometimes works (ie it doesnt hang)
but I've no idea why. Has anyone experienced similar problems with this? Or
does anyone have any alternative suggestions? I'm really at my wits end with
this one!
thanks alot,

This is going to be a pretty vague message because it involves a large block of code I'd rather avoid posting.

Hi all, I have a problem using wget and Popen.

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

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...
