I have been looking at exceptions as I need to get better at using
them.
I came across an interesting effect, demonstrated below. When I
ctrl-Z the input to throw an ios_base::failure, the first line of
output from cout is lost, even if I clear() and flush(). The only way
I have found to get the first line to appear is to put a newline at
the start. It seems to be ignoring everything up to and including the
first newline.

I was recently asked this question in an interview. Unfortunately I was
not able to answer it and the interviewer made a decision on my C
strengths (or weekness) based on this single question and that was a
sad end to my interview. Here is the program:
#include <stdio.h>
int main()
{
char *c ="abc";

I have written some programs in c lang yet but today I get confused
with output i get.
I have function educate(..) which i call in main program this way:
J = educate(no_layers, no_neurons, input, output, lay, weights, 0.1,0);
printf("J= %f\n",J);
In the educate function i count J and i return it (but before I return
it I output it with printf):

I have a small training database: sql_tutorial. It works fine but the spacing
between the output lines is too much. This is the way it looks when I copy
and paste from the Konsole to this email:

I have the following SQL with explain
Should I be concerned with the merge cond: Merge Cond:

Hello,
one sql statement is causing severe performance issue. The problem occurs only in UDB environment, the same statemnt on the mainframe is running fine. I have an explain output from the sql. The statement itself is not that complicated, it is 3 selects and union all. Explain output is pretty big, but I could not find anything unusual. I'm new to db2 and I could be missing stuff. I am posting the explain output below and I really...

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...

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...
