Rust: Variations of a Thing - Enums

Enums in Rust are a type of data structure useful for enumerating possible variants of something.
Enums can contain data, making them flexible and customizable.
To use an enumeration, match keyword is used to access and manipulate the data contained in the enum.
Enums are a core part of Rust's powerful type system and are used for creating custom data types.

How Python’s Descriptor Protocol Implements Attribute Access

The descriptor protocol is a fundamental mechanism in Python that governs how attribute access — retrieval, assignment, and deletion — is handled.
It operates through a set of specially defined methods that are implemented in a class, enabling precise control over the behavior of attributes.
These methods, __get__, __set__, and __delete__, are invoked automatically during attribute access operations when a descriptor object
__get__ method when obj.attr is accessed. This overrides the default behavior of retrieving the value directly from the instance's __dict__.
When an attribute is accessed, Python executes a series of well-defined steps to resolve the attribute's value.
Descriptors are typically defined at the class level, meaning they exist as part of the class definition
A descriptor is classified as a data descriptor if it defines the __set__ method or the __delete__ method
data descriptors, by implementing __set__, control both retrieval and assignment of attributes, bypassing the instance’s __dict__.
non-data descriptors, which lack __set__, allow instance attributes to take priority over the descriptor.
This architecture underpins many core Python features, such as property objects and method binding, offering fine-grained control over how attributes behave.

Understanding Large Language Models(LLM’s): How They Work and Why They Matter

Large Language Models (LLMs) are AI models trained to process and generate text using massive datasets.
LLMs understand patterns of language to predict the next word in a sentence or generate coherent text.
They work using neural networks, mimicking the human brain's functioning.
LLMs are important for various applications like natural language processing and generating human-like text.

Count the number of 1’s in an array sorted in decreasing order.

The given problem is to count the number of 1's in an array that is sorted in decreasing order.
To solve this problem, we can use binary search.
We find the last occurrence of 1 in the array and return its index + 1 as the result.
If the mid index is not the last index of 1, we move towards the right half; otherwise, we move towards the left half.

Search An Element in Bitonic Array

The problem is to search for an element in a bitonic array.
A bitonic array is an ascending sorted array that starts descending after a particular element.
The solution involves finding the peak element in the bitonic array using binary search.
Then, a binary search is performed in the ascending and descending halves of the array to search for the given element.

Find maximum element in Bitonic Array

Given a bitonic array, the task is to find the maximum element.
A bitonic array is an ascending sorted array that starts descending after a particular element.
The problem can be solved using binary search technique.
The maximum element in the bitonic array is found by comparing mid element with its neighboring elements.

Find the index of first 1 in an infinite sorted array of 0s and 1s

The problem is to find the index of the first occurrence of 1 in an infinite sorted array of 0s and 1s.
To solve this, we can apply binary search. However, to apply binary search, we need to know the start and end indices of the array.
To find the end index, we start with index 1 and keep doubling it until we find a 1.
Once we have the start and end indices, we perform binary search to find the first occurrence of 1.

Find position of an element in an Infinite Sorted Array

To search for an element in an infinite sorted array, we can use binary search.
However, to apply binary search, we need to find the end index.
To find the end index in an infinite array, we can start with a starting index and double the end index until we find an element greater than the key element.
Once we have the start and end indexes, we can apply binary search to find the key element's position.

What are JavaScript Engines?

JavaScript engines are process virtual machines designed to interpret and execute JavaScript code.
The basic job of a JavaScript engine is to convert the JavaScript code that a developer writes to fast, optimized code.
Each JavaScript engine implements a version of ECMAScript. As ECMAScript evolves, so do JavaScript engines.
JavaScript engines work differently. For example, JavaScriptCore by Apple performs a series of steps to interpret and optimize a script.
Google’s V8 engine, written in C++, compiles and executes JavaScript source code, handles memory allocation, and garbage collects leftovers.
Runtimes tend to work on top of JavaScript engines, extending their power.
A lot of marketing push goes into the names given to JavaScript engines. However, it’s useful to note a few of the major events in the history of the JavaScript engine.
The goal of a JavaScript engine is to generate the most optimized code in the shortest possible time. Keeping up with the changes in JavaScript engines will be time well spent as you evolve as a web, mobile, or app developer.
Understanding the tech behind JavaScript engines can help in better honing the craft as a programmer.
Developers should be aware of the differences inherent in the browsers that display the code and understand the limitations inherent to and possibilities offered by the various browsers on their small devices.

Real-time Log Streaming with Node.js and React using Server-Sent Events (SSE)

This guide demonstrates how to create a real-time log streaming system using Server-Sent Events (SSE) with a Node.js backend and React frontend.
Server-Sent Events (SSE) is a one-way, real-time technology that lets servers push data to web browsers.
SSE is perfect for scenarios where you only need to send data from server to client, like log streaming as it is simpler than WebSockets to implement and works automatically with HTTP/HTTPS.
The Node.js backend log streaming service has to set up with headers for SSE.
SSE server must follow a specific message format, which includes the following details → tells the browser it's a message payload.
The React component displays streaming logs and has to create an SSE connection which handles incoming messages, errors, and cleans up on unmount.
It provides real-world usage examples such as processing large files and database operations.
Tips and best practices include Memory management, Performance optimization, Enhancing User Experience, and Security Measures.
Server-Sent Events are simple to implement, provide real-time updates and work automatically with HTTP/HTTPS, making them perfect for scenarios where data is only one-way.
Remember to handle errors properly, manage memory usage, and consider security implications while implementing this in a production environment.
