Running python 2.3.4 on valgrind (a tool like purify which checks
the use of uninitialized memory, etc), gives a lot of errors.
See below.

Hi
I have been using valgrind to debug a program I have written in C++ and
it has been very helpful in eliminating memory errors/leaks. However, I
just recently discovered a bug and from what I can see it looks like
some kind of memory problem. However, when I run it through valgrind no
errors are reported and the bug seems to be gone! I print some status
from the program and at some point this becomes wrong but when the
program is run...

For C#, to access an internet page i usually type:
System.Diagnostics.Process proc = new System.Diagnostics.Process();
proc.EnableRaisingEvents = false;
proc.StartInfo.FileName = "iexplore";

It's entirely possible that I'm completely in the wrong line of work,
but I don't see what Valgrind is complaining about in this code.
Invalid read/writes?
If I free the within main(), rather than within free_node_list(),
Valgrind reports 0 leaks?

Hi,
I'm using the pexpect module to spawn some processes in a testing
environment. pexpect uses, internally, os.execv. What I need to do is
valgrind python and get memory leaks from the spawned children
(assuming that python doesn't leak :)).
Here's a simple testcase:

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:

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,...

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...
