Does it mean "(sizeof(int))* (p)" or "sizeof( (int)(*p) )" ?
According to my analysis, operator sizeof, (type) and * have the same
precedence, and they combine from right to left. Then this expression should
equal to "sizeof( (int)(*p) )", but the compiler does NOT think so. Why?
Can anyone help me? Thanks.
Best regards.

I have noticed that the meaning of visibility: collapse has been discussed
on different forums, but with no consensus on what it really means.
Besides, implementations differ.
The specification says:
"The 'visibility' property takes the value 'collapse' for row, row group,
column, and column group elements. This value causes the entire row or
column to be removed from the display, and the space normally taken up by
the row or column to...

Some of the classes in the framework are marked as thread-safe in the
documentation. In particular the docs say the following:
"Any public static (*Shared* in Visual Basic) members of this type are
thread safe. Any instance members are not guaranteed to be thread safe."
What exactly does this mean? Does this mean that if I call a shared
method from 2 different threads, nothing whacky will happen?
Also when it says that instance members...

TcpClient has a method called GetworkStream GetStream();
So in other words, there is only one stream associate with it for input and
output, right?
So while it is receiving, it can not send, and vise visa, right? So will it
be a problem both server and client can initiative a sending action?
TcpClient only supports synchronous operation. What does "Synchronous" mean?
Means while it is reading or waiting for data to arrive from the...

In the main program I check to see if a certain form has been disposed.
Does it make sense in that form's FormClosed event to do:
Me.Dispose to make sure it is disposed the next time I check.
Or is that automatic?
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

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....

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...
