Happened to see my old (last millennium) c code. Almost forgot that I
wrote it .
It is interesting. :-)
int sqrt(int no)
{
int t;
no = t * t;
return t;
}

I thought it might be interesting to share experiences of tracking down a
subtle or mysterious bug. I myself haven't much experience with tracking
down bugs, but there's one in particular which comes to mind.
I was writing usable which dealt with strings. As per usual with my code, I
made it efficient to the extreme. One thing I did was replace, where
possible, any usages of "strlen" with something like:
struct PtrAndLen {
char *p;

An interesting/annoying problem.
I created a small example to provoke an exception I keep getting.
Basically I have a C-struct (Container) with a function-pointer in it.
I perform repeated calls to the function in the container. I allocate
(and free in c) arrays to get garbage collection in both C and C#.
After a few seconds I get an exception.
I assume GarbageCollector moves the delegate (or collects is) and when
I don't find it in C...

Hello all,
First let me appologise if this has been answered but I could not find
an acurate answer to this interesting problem.
If the following is true:
C:\Python25\rg.py>python
Python 2.5.1 (r251:54863, Apr 18 2007, 08:51:08) on
win32
Type "help", "copyright", "credits" or "license" for more

I wrote two trivial test programs that do a billion iterations of a
virtual method call, first in C# (Visual Studio 2005):
Thing t = new DerivedThing();
for (System.Int64 n = 0; n < 10000000000; n++)
t.method();
Then in C++ (using Visual C++ 2005):
Thing *t = new DerivedThing();

I really want to revive this discussion. Arnaud's approach is

Try to use it to draw a simple non-anitaliased line in a standrad

Buffer overflows are a fact of life, and, more specifically, a fact of
C.
All is not lost however. In the book
"Value Range Analysis of C programs" Axel Simon tries to establish a
theoretical framework for analyzing C programs. In contrast to other
books where the actual technical difficulties are "abstracted away",
this books tries to analyze real C programs taking into account
pointers, stack frames, etc.

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

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...
