hi,
recently i discovered a memory leak in our code; after some investigation i
could reduce it to the following problem:
return objects of functions are handled as temporary objects, hence their
dtor is called immediately and not at the end of the function. to be able to
use return objects (to avoid copying) i often assign them to a const
reference.
now, casting a const return object from a function to a non-const reference
to this...

Hello,
I couldn't find a solution to the following problem (tried
google and dejanews), maybe I'm using the wrong keywords?
Is there a way to open a file (a linux fifo pipe actually) in
nonblocking mode in c++? I did something ugly like
--- c/c++ mixture ---
mkfifo( "testpipe", 777);

Is it at all possible to leverage mixed-mode assemblies from AppDomains
other than the default AppDomain? Is there any means at all of doing this?
Mixed-mode is incredibly convenient, but if I cannot load/unload/reload
extensions into my large and slow-to-load application during development
without restarting the process then the disadvantages may outweigh the
advantages.
I've got a mixed-mode program in which I create a new AppDomain...

Hello All,
So far I have been reading that in case of a polymorphic class ( having
at least one virtual function in it), the virtual function call get
resolved at run time and during that the vtable pointer is made use

I need help writing a function for a program that is based upon the various operations of a matrix and I keep getting a "non-aggregate type" error. My guess is that I need to dereference my pointers, but I'm not sure. Please help.
The code:
void equate(matrix *A, matrix *B)
{
int i, j;
assert(A.row_dim == B.col_dim && A.col_dim == B.col_dim);
for(i=0; i < A.row_dim; i++)
for(j=0; j < A.col_dim; j++)

Secure Socket Layer is very important and useful for any web application but it brings some problems too with itself. Handling navigation between secure and non-secure pages is one of the cumbersome jobs.
When a non-secure page references a secure page with relative URL, the web server generates error until absolute URL with https prefix is used. On the other hand when a secure page references a non-secure page, the non-secure page will be...

PEP 1 specifies that PEP authors need to collect feedback from the
community. As the author of PEP 3131, I'd like to encourage comments
to the PEP included below, either here (comp.lang.python), or to
python-3000@python.org
In summary, this PEP proposes to allow non-ASCII letters as
identifiers in Python. If the PEP is accepted, the following
identifiers would also become valid as class, function, or
variable names: Löffelstiel,...

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,...

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...

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...
