Hi,
Given a collection of similar but not exact entities (or products)
Toyota, Ford, Buick, etc; I am contemplating using the Abstraction pattern
to provide a common interface to these products. So I shall have an
Abstract Base called 'Car' implemented by Toyota, Ford, and Buick.
Further I'd like to enable to client to say
Car *factory;

I've hit something of a snag.
Problem:
In a DSP application we have data profiles with a varying number of points.
We have a number of Discrete Fourier transforms that are optimised for a
specific number of points. Currently, any client of these DFT classes must
switch on the number of points in the profile and instanciate the correct
DFT algorithm.

Beside its an opensource and supported by community, what's the fundamental
differences between PostgreSQL and those high-price commercial database (and
some are bloated such as Oracle) from software giant such as Microsoft SQL
Server, Oracle, and Sybase?
Is PostgreSQL reliable enough to be used for high-end commercial
application? Thanks

Hi,
I need to parse a binary file produced by an embedded system, whose
content consists in a set of events laid-out like this:
<event 1<data 1<event 2<data 2... <event n<data n>
Every "event" is a single byte in size, and it indicates how long is
the associated "data". Thus, to parse all events in the file, I need to
take it like a stream and read one event at a time, consuming bytes

Hi,
I've run into a strange problem, but one that seems like it might be
fairly common.
I have a single base class, from which several other classes are derived.
To keep the example simple, the base class is "Animal" and the derived
classes are "Cat," "Dog," and "Horse."
The base class has a pure virtual method:

I have a class which is not intended to be instantiated. Instead of using
the class to creating an instance and then operate on it, I use the class
directly, with classmethods. Essentially, the class is used as a function
that keeps state from one call to the next.
The problem is that I don't know what to call such a thing! "Abstract
class" isn't right, because that implies that you should subclass the
class and then instantiate the...

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...
