Deep Copy vs. Shallow Copy
- A shallow copy creates a new object or array that has the same top-level properties as the original.
- However, if any properties are references to other objects, only the references are copied.
- Changes to nested objects or arrays in the copied object will affect the original object, as both reference the same memory location.
- A deep copy creates a new object or array and recursively copies all properties from the original object, ensuring that nested objects are independent.

The Worlds First Computer “Bug”
- In 1947, engineers at Harvard encountered a problem with the Mark II Aiken Relay Calculator, a large computer used by the U.S. Navy.
- After investigating, they discovered that the problem was caused by a moth trapped in Relay #70, Panel F.
- The engineers removed the moth with tweezers and taped it into the logbook, coining the term 'debugging' as a result.
- The story of the moth serves as a reminder that even the most advanced technology can be affected by small, unexpected issues.

Time Series Analysis: Reading the Rhythms Hidden in Data
- Traditional modeling approaches often fail to capture complex temporal dynamics such as seasonality and nonlinear relationships.
- Time-aware cross-validation reveals the limitations of linear regression on the classic AirPassengers dataset, particularly in modeling seasonal fluctuations.
- The results indicate the necessity of enhanced feature engineering or more advanced models to improve forecasting performance in time series analysis.
- Incorporating seasonality or adopting architectures like ARIMA or LSTM can significantly enhance time series forecasting.

Why the Software Development Life Cycle (SDLC) Matters – and How to Implement It Effectively
- The Software Development Life Cycle (SDLC) is a systematic process that guides the development of software applications from initial concept to deployment and maintenance.
- It encompasses several phases, including requirement analysis, design, implementation, testing, deployment, and maintenance.
- Implementing SDLC offers benefits such as improved project management, enhanced quality assurance, risk mitigation, cost efficiency, better communication, and regulatory compliance.
- To implement SDLC effectively, it is essential to engage stakeholders, choose the appropriate model (such as Waterfall, Agile, or Spiral), maintain comprehensive documentation, incorporate testing throughout, and have a post-deployment support plan.
