Should an if statement have a corresponding else statement? Or, is it OK
to have an if statement by itself. For completeness, it seems the two
should be together, but from experience I know that a if statement by
itself works just fine. Below is an example:
if x >=0:
DO SOMETHING
Would it be better, or perhaps more complete, written like this:

here's the scenario..
I am running a DTS to collect the summarized info from Oracle database
into SQL server. I then have a update job which updates my
transactional table from the summarized table.
The update takes a very long time (~ 3 minutes)even though it has
around 1500 rows which causes the application to timeout. I want this
job to be done in less than a minute.

I had a very large number of query statements that I had converted to
SQL a long time ago aticipating that I would some day upsize my
application. Every now and then when I do an import to a new
application, some of the forms will import corrupted, and crashing the
whole application, though it works fine in the old application.
Today I did some experimenting on the two most recent corrupt form

I recently posted a question which was answered by Allen Browne and gave me
some tips to structure the tables. However, when it comes to searching the
database, performance is unacceptably slow and I am now thinking of doing
the unthinkable with my tables and wonder whether anyone has used (or still
uses) this sort of approach.
The database stores libraries and classifies the types of book they keep. So
I have the classic 3-table...

Hi,
we are currently using another database product but besides some
licensing issues we are finding more and more problems with the
database. We are evaluating PostgreSQL and it looks quite handy.
Interesting features paired with good performance and a lot of users
seems to be a prove for the quality.
I wonder if people encountered bugs like 'a select returns a wrong
number of rows' or any other very serious bugs. We do not have...

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....

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...
