What's going on with Javascript.
At the beginning there was the "undefined" value which represented an
object which really didn't exist then came the null keyword. But
yesterday I stumbled across "null" string.
I know that I will get an "undefined" when I try to retrieve something
from the DOM which doesn't exist.
I have used null myself to initialize or reset variables. But in which

Hi all,
I am new to C and I just started to program for a homework.
I included my code down there.
It is a fraction "class". I declared the Fraction struct, tried to
create some invalid fraction, with denominator zero.
A Fraction is created by the newFraction() function, and which in turns
call normalize() function to simplify it, but before, the normalize()
function will do a check, if the denominator is zero, it will give a
error by...

Hi,
I have made two classes, which are simple and almost same,
T_A and T_B.
T_A has a static method overloaded to "==".
T_B dosn't.
And, I run the following code. I expect both "a" and "b"
show the messagebox. But, only "b" showes the messagebox.
Even I try to see "a" through visual studio, "a" is

Hi,
My question is related to setting freed pointers to NULL.
After freeing a pointer:
1) Should the freeing routine also be responsible for setting the
pointer to null?
2) Or, should the client/user code be responsible for doing it?
On what basis should a decision be made favouring either case ?

Hi guys:
We've been weeding out errors off of a java->c# project and have managed to redeem most of our code with the exception of one bug that we for some reason cannot pin down.
The following is an implementation of Linked List class for any item "E" (that also implements IMatchable for itself). It defines "LinkedList" as a recursive datatype with no separate "Cell" or "Node" class, much the same as say for instance ML's Programming...

Howdy everyone,
I'm experiencing a problem with a program that I'm developing. Take a
look at this stack report from GDB -

Is that a non-conformance?

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

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...

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...
