I asked a lot of questions in May about how to organize OO code. I
didn't get great answers here, but someone here suggested that I look
the Eclipse library, which was a good tip. Looking at its small,
simply objects was an education for me.
What I was wondering, when I rewrote my cms from procedural code to OO
was how to avoid end up have every class called by ever other? I was
writing massive objects where every object needed every...

Hi all,
I hope this is the right place for this post, apologies if it is not.
I am trying to write a program that creates an input file for a dispersion
model. The model is expecting a Fortran "unformatted" binary file in
big-endian. However, my program is written in dotnet and I'd like to avoid
writing and then calling a Fortran program to do this one task. My question
is:

Hi,
I have an application where i want to write data to a file, the data is
being sent from an external source. I know the total size of the data and
then i retrieve the data in small segments from the source. This data is
written to file in a loop.
My question.
1. Will it be useful to increase the file size initially then seek to 0 and
start writing to file. whether there will be any performance improvements

Jargons of Info Tech industry
(A Love of Jargons)
Xah Lee, 2002 Feb
People in the computing field like to spur the use of spurious jargons.
The less educated they are, the more they like extraneous jargons, such
as in the Unix & Perl community. Unlike mathematicians, where in
mathematics there are no fewer jargons but each and every one are

I'd like to get some feedback on the issue of storing data out to disk and
where to store it. I've never been in a production environment in
programming so you'll have to bear with me...
My question is about storing data in a database. Yes I understand that you
can link to a database in your program and read and write to the database
etc etc. Well, that's all find and dandy but what if the person you're

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...
