compile SpiderMonkey ( libjs / libjs.so / libjs.dylib ) for OS X
(10.4.5 in my case) and then use it with Python's ctypes. I can't say
this will work for anyone else, but it worked for me...

You're right the ctypes does seem more pythonesque; however I'm still stuck trying return all these parameters
that the c api uses. my ctypes code is below. It just quits running when I try to print
one of the args I did a pass byref on, no error out, nothing. admittedly I'm a newbie to ctypes and not much of a c programmer
but I could sure use some help. my ctypes test code follows...

I need to call a function in a shared object with this signature:
init_dialog(FILE *input, FILE *output)
The FILE*'s are to stdin and stdout.
The call from python is libdialog.init_dialog( x, y)
I need to define x and y so that they will have the structure of
sys.stdin and sys.stdout; the called function (init_dialog) is using a
(std?) function fileno to extract the fileno from the FILE* describing
stdin and stdout.
How can I do this?

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

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...
