Birth of JavaScript: 10 Days, One Man, and a New Era
- In 1995, JavaScript was created by Brendan Eich in just 10 days, becoming the widely-used programming language on the internet.
- JavaScript was developed to add interactivity, validation, and dynamic behavior to the web, which was previously static.
- Netscape, the dominant browser company at the time, sought a lightweight scripting language for web designers, leading to the creation of JavaScript.
- Java and C++ were not suitable for client-side scripting on browsers, prompting the need for a more accessible language like JavaScript.
- Initially named Mocha and LiveScript, JavaScript was later coined as a marketing tactic to ride the popularity wave of Java.
- JavaScript was designed around the needs of the early web, focusing on functions as first-class, prototypal inheritance, and browser event-driven interactions.
- Despite initial bugs and inconsistencies, JavaScript survived and evolved to become the most crucial language for web development.
- JavaScript's impact has lasted for decades, revolutionizing the web with its ability to bring interactivity and dynamism to web pages.
- Episode 2 will explore how JavaScript overcame challenges and emerged as a pivotal language on the internet.
- The journey of JavaScript showcases resilience, evolution, and significance in shaping the modern web landscape.

Why is my React component flickering?
- React component re-renders can happen even if no visible change occurs.
- React.memo can be used to prevent unnecessary re-renders in components that do not change.
- Using useMemo with Context can ensure the value remains the same if the data hasn't changed.
- Context re-renders children if the value changes, even if the value appears the same.

Seeing the World: A Beginner's Guide to Convolutional Neural Networks (CNNs) with PyTorch
- Convolutional Neural Networks (CNNs) are powerful neural networks specifically designed for handling image data and have revolutionized computer vision.
- Traditional neural networks face challenges with image data due to the large number of parameters, slow training, and lack of spatial understanding.
- Convolutional layers in CNNs use filters to efficiently process images, providing parameter efficiency, location invariance, and hierarchical feature learning.
- Essential CNN operations include zero padding for controlling spatial dimensions and max pooling to reduce spatial dimensions and complexity.
- A typical CNN architecture consists of a feature extractor (convolutional layers and pooling) and a classifier (linear layers for prediction).
- Activation functions like ReLU are crucial for CNNs to learn complex patterns, and handling image data in PyTorch involves using torchvision library.
- Data augmentation, training loop definition, and evaluation metrics like accuracy and F1 Score are essential for training and evaluating CNN models.
- Strategies to combat overfitting in CNNs include dropout, batch normalization, weight decay, and early stopping.
- Modern CNN architectures like VGG, ResNet, Inception, and EfficientNet offer improved performance and are available for transfer learning.
- Understanding how CNNs process images and utilizing techniques like data augmentation and regularization are key to building robust computer vision models.

Interpolation instability
- Interpolating at more points does not always give a more accurate approximation, as demonstrated by the famous example by Runge.
- Runge's example shows that interpolating 1/(1 + x²) over the interval [-5, 5] with more interpolation points can actually increase the maximum interpolation error.
- Factors that contribute to Runge's example include evenly spaced interpolation nodes and singularities in the complex plane too close to the domain.
- Using Chebyshev nodes and interpolating analytic functions around the unit interval can mitigate the issues of interpolation instability.
