Hi all.
Handling files is an extremely frequent task in programming, so most
programming languages have an abstraction of the basic files offered by
the underlying operating system. This is indeed also true for our language
of choice, Python. Its file type allows some extraordinary convenient
access like:
for line in open("blah"):
handle_line(line)

Meanwhile there are at least 8 years that compilers exist,
which provide a working implementation of C++ Exception Handling.
Has anything changed meanwhile?
From my point of view nothing has changed
-- people are still using a coding style, which I call
pre-C++-Exception-Handling.
Is this different in your experience?
What is your experience regarding this subject?
I think that a C++ IOstream lib, which is by standard free of exceptions...

Some time ago, I remember reading a discussion about the strengths and
weaknesses of exception handling. One of the weaknesses that was put
forward was that exception handling is inefficient (in the way of CPU
usage), compared to the "normal" practise returning values.
How true is this? Will using using exception handling, in general, be
much less efficient than returning values, or less efficient at all?
Just curious...

Say I've created a piece of code that involves both sql, io and some number
conversions. Being a responsible developer I have tried to catch all of the
exceptions - but how can I be sure?
Is there a way to list exactly which exceptions that are not handlet?
(design time)
I could of cause ... use catch (Exception e) {...} as the final catch ...
but I would prefer to now the "landscape" before doing that ..

I have read that Exception Handling is expensive performance wise ( other
than Throw ) , but exactly how ?
Please consider the following example ...
////////////////// Code Block 1 //////////////////////////////////
Try
{
for ( ... ){// Code that might throw exception}
}catch(...){}
//////////////////////////////////////////////////////////////////////////

Hi,
Considering the scenario for handling exceptions in Web Application where we have Presentation layer, Business layer and Data Access layer; if there any exception is occurred in DAL, what is the best thing to do:
1. Dont catch the exception in DAL and let it prop up to the Application level and the Global.Application_Error event log it to any source and show let ASP.NET show custom error page provided in Web.Config file.
OR
2....

I'm implementing a centralized exception handling routine using the
Enterprise Library Exception Management Application Block.
I trap all unhandled exceptions to one place using the following method:

I've created a class that offers an enhanced way of handling fatal
exceptions. The class allows the user to optionaly submit a http based
anonymous error report to myself, and also records details in the
application log. The static method is overloaded, and supports passing
exceptions and/or strings just like throwing an exception.The class
will also fall back to the standard exception handling if something
goes wrong in my class.

I'm interested in an idiom for handling errors in functions without
using traditional nested ifs, because I think that can be very awkward
and difficult to maintain, when the number of error checks gets about
3 or so. It also gets very awkward in nested loops, where you want to
check for normal loop processing in the loop condition, not errors.
Yes, you could put some generic exit flag in the loop condition, but
when you're simply done if...

Python provides a quite good and feature-complete exception handling
mechanism for its programmers. This is good. But exceptions, like any
complex construct, are difficult to use correctly, especially as
programs get large.
Most of the issues of exceptions are not specific to Python, but I
sometimes feel that Python makes them more acute because of the free-n-
easy manner in which it employs exceptions for its own uses and allows
users...

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...

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,...

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...

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.
