Writing SOLID code

-
In computer programming, SOLID (Single responsibility, Open-closed, Liskov substitution, Interface segregation and Dependency inversion) is a mnemonic acronym introduced by Michael Feathers for the "first five principles" identified by Robert C. Martin in the early 2000s that stands for five basic principles of object-oriented programming and design. The principles when applied together intend to make it more likely that a programmer will create a system that is easy to maintain and extend over time. The principles of SOLID are guidelines that can be applied while working on software to remove code smells by causing the programmer to refactor the software's source code until it is both legible and extensible. It is typically used with test-driven development, and is part of an overall strategy of agile and adaptive programming.

S - SRP - Single Responsibility Principle - A Class should have only a single responsibility.
O - OCP - Open/Close Principle - Entities should be open for extension but closed for modification
L - LSP - Liskov Substitution Principle - objects in a program should be replaceable with instances of their subtypes without altering the correctness of that program
I - ISP - Interface Segregation Principle - many client-specific interfaces are better than one general-purpose interface
D - DIP - Dependency Inversion Principle - one should “Depend upon Abstractions. Do not depend upon concretions.

Navigating the Jungle of Web Traffic: A Technical Team Lead's Guide to "I'm a Celebrity, Get Me Out of Here"

-
"I'm a Celebrity, Get Me Out of Here" has become a cultural phenomenon, captivating audiences worldwide with its thrilling challenges and celebrity antics. As a Technical Team Lead, preparing for the surge in traffic during the show's broadcast is akin to navigating a dense jungle of user interactions. In this article, we'll explore the strategies and considerations that technical teams can employ to ensure a seamless online experience while aligning with marketing promotions. 1. Assessing the Infrastructure: Before the chaos ensues, evaluate your web infrastructure. Ensure that servers are optimized, databases are finely tuned, and CDN (Content Delivery Network) configurations are robust. Conduct load testing to simulate peak traffic and identify potential bottlenecks. This step is crucial for preventing server crashes and maintaining site performance under increased load. 2. Scalability and Elasticity: Consider implementing auto-

TCP Handshake over IPv6

-
The internet we know today heavily relies on TCP/IP to send our information around the world at lightspeed.  With more devices than ever connected to the internet (insert link to back this up, it sounded cool), using IPv4 we're soon going to run out of addresses.  And in fact if it weren't for technologies such as NAT we'd be in a stickier situation than we already are.   In preperation of running out of IP addresses, IPv6 was mustered up around 1998 by the IETF, a 128-bit addressing convention vs the old IPv4 32-bit addressing. So that means IPv6 has been around quite a while now.  Almost 20 years, yet still IPv4 is all the rage.  Perhaps us techies have trouble letting go of what we know.   I mean why set up an AAAA record, when you only need to set up an A record right?  Why configure DNS to use   2001:4860:4860:0000:0000:0000:0000:8888 or 2001:4860:4860::8888 when you can just use 8.8.8.8 right?  Well yeah, let's save all that for another article, once I've h

The Vital Importance of Secure Wi-Fi Networks

-
In today's digitally interconnected world, Wi-Fi has become an indispensable part of our daily lives. From homes to businesses, coffee shops to airports, we rely heavily on wireless networks to stay connected. However, amidst the convenience and ease that Wi-Fi brings, security should never be taken lightly. In this blog post, we'll delve into the critical importance of using secure Wi-Fi networks and the potential risks associated with neglecting this aspect of our online lives. The Threat Landscape First and foremost, let's address the ever-looming threats that exist in the digital realm. Unsecured Wi-Fi networks are a goldmine for cybercriminals, as they provide an easy entry point to intercept sensitive data. When you connect to an open, unencrypted Wi-Fi network, your data becomes vulnerable to eavesdropping and interception. Malicious actors can capture login credentials, personal information, and even financial details, putting you at risk of identity theft, financi
