hi
i would like to pickle a lambda; according to the library docs in 2.3,
i believe this shouldnt be possible, since a lambda is not a function
defined at the top level of a module (?)
however, upon google searching for "python lambda pickle" i find 2
posts, one including gvr, which apparently demonstrate that this was
being attempted and even suggest that it is feasible. has this become
available yet, or will it be soon?

Hi all,
After some research I've decided that my previous question (Confusing
problem between Tkinter.Intvar...) was headed in the wrong direction.
Partly because I think I have a greater understanding of what was
happening, and partly because pickling Tkinter widgets is an issue
that seems to have been touched on over the years but never really
acted on.
Postings back to '96 have talked about the need to pickle Tk widgets.

I'm having trouble pickling subclasses of dict when they contain cycles.
In particular:
>>> import pickle
>>> class D(dict): pass
>>> d = D()
>>> d = d # add a cycle.
>>> print d
{1: {...}}
>>> pickle.dump(d, open('d.pickle', 'w'))

Dear all,
I have a long running application (electromagnetic compatibility
measurements in mode-stirred chambers over GPIB) that use pickle
(cPickle) to autosave a class instance with all the measured data from
time to time.
At the beginning, pickling is quite fast but when the data becomes more
and more pickling slows down rapidly.

Hi all, happy new year,
I was trying to pickle a instance of a subclass of a tuple when I ran
into a problem. Pickling doesn't work with HIGHEST_PROTOCOL. How should
I rewrite my class so I can pickle it?
Thanks ,
Fedor

I have a serious problem and I hope there is some solution. It is
easier to illustrate with a simple code:
>>> class Parent(object):
__slots__=
def __init__(self, a, b):
self.A=a; self.B=b
def __getstate__(self):
return self.A, self.B
def __setstate__(self, tup):

Hi all,
I have an application were i want the user to "configure" some settings
which are variables within different classes.
My question is should i just pickle out these variables to a file in
some particular order then read it back. Or use xml to save the config
values ? Which one scales better if settings increase?
Other sugestions?

If I gather correctly pickling an object will pickle its entire hierarchy,
but what if there are certain types of objects anywhere within the hierarchy
that I don't want included in the serialization? What do I do to exclude
them? Thanks.

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,...

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...
