Hi,
I am at the end of my tether now - after spending several days trying to
figure how to do this. I have finally written a simple "proof of
concept" program to test serializing a structure containing pointers
into a "flattened" bit stream.
Here is my code (it dosen't work - compiles fine, pack appears to work,
but unpack retrieves jibberish and causes program to crash).

Hi,
I am writing a messaging library which will allow me to send a generic
message structure with custom "payloads".
In many cases, a message must store a non-linear data structure (i.e.
"payload") using pointers. Examples of these are binary trees, hash
tables etc. Thus, the message itself contains only a pointer to the
actual data. When the message is sent to the same processor, these
pointers point to the original locations, which...

Hi.
In the snippet of code below, I'm trying to understand why when the
struct dirent ** namelist
is declared with "file" scope, I don't have a problem freeing the
allocated memory. But when the struct is declared in main (block scope)
it will segfault when passing namelist to freeFileNames().

Using javascript closures to create singletons to ensure the survival
of a reference to an HTML block when removeChild() may remove the last
reference to the block and thus destory the block is what I'm hoping to
achieve.
I've never before had to use Javascript closures, but now I do, so I'm
making an effort to understand them. I've been giving this essay a

I try to understand what could be the source of a problem with
displaying and hiding rows of tables using display:block/none.
I've read selfhtml but could not find any hint about that. Any
pointers why that can happen, or how I should take care of that
type of problem/effect are highly appreciated.
The problem...
A couple times the hiding/displaying works, but _occasionally_
the entries are hidden but _blank lines appear_, instead.

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...

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...
