Programming is not just about writing instructions that a computer can follow; it is also about communicating with other developers who will read, maintain, or extend the code. One of the most effective ways to make code readable and professional is by using consistent naming conventions, commonly referred to as programming case styles. These styles dictate how variable names, function names, class names, constants, and other identifiers are structured. Different programming languages, teams, and frameworks adopt different case styles depending on tradition, readability, and standardization preferences. Understanding these styles and…

As organizations across sectors continue to face increasing threats to their digital assets, there is a…

Pivot Tables are an incredibly powerful tool in Excel, allowing users to analyze and summarize large volumes of data quickly and effectively. By rearranging and grouping data, Pivot Tables help make complex datasets understandable and actionable. However, one key point that users often overlook is that Pivot Tables do not update automatically when the source data changes. This means that if your underlying data is modified—whether by adding new records, deleting entries, or making corrections—your Pivot Table will still display the previous data until it is refreshed. This behavior is…
