The Top Level Design:
The class Base is a factory class with a twist. It uses the Assembly/Type
classes to extract all types that inherit from it and add them to the list
of types that inherit from it. During run time, using a static method, the
class creates an instance of the derived class using the Activator class and
returns it. This design pattern is very similar to the design pattern
applied by the Assembly class.
The twist is...

In Febraury - April of 2002 I put together in Java examples of all 23
of the classic "Gang Of Four" design patterns for my website. Partly
I wanted to get a better understanding of those patterns. They are
still online at
http://www.fluffycat.com/java/patterns.html
Since September 2003 I've mainly been using PHP, and now that PHP 5 is
becoming more available I am going to try the same thing I did in Java
with PHP.

Hello NG,
i am just learning various Design Patterns and now i am not sure, if
this design is correct (Builder) or if i should use an other pattern.
I have various classes (here ChildA and ChildB) derived from class Base.
Now i want to create an object, but i don't want to know which class to
instantiate.

Hi,
I have been stuck trying to come up with a design for days. I am working on
a small project regarding barcode and I want to implement a factory design. I
am now confused.
I decided factory pattern since I am dealing with EAN13, UPCA12 UPC8 etc.
Can someone provide a small sample on how to start. I have looked at the
factory implementation online but still can't figure it out. Can someone
provide a sample jsut to start with.

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies.

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.
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...
