5/5 - (1 vote) Tesla is doubling down on its focus on becoming the global leader for large-scale AI applications such as self-driving cars and humanoid robots: “While many are pulling back on their investments, we are investing in future growth – including our AI infrastructure, production capacity, our Supercharger and service networks and new products infrastructure – with $2.8B of capital expenditures in Q1. […] The future is not only electric, but also autonomous. We believe scaled autonomy is only possible with data from millions of vehicles and an immense AI training cluster. W ..read more

5/5 - (1 vote) Python’s magic methods __new__ and __init__ play complementary roles in the lifecycle of an object: __new__ is a static method, primarily concerned with creating and returning a new instance of a class; it acts before the object is fully instantiated in memory. Following this, __init__ functions as an instance method, tasked with configuring the specific attributes of the newly minted object, thus defining its initial state. This orchestrated sequence ensures that the structural foundation established by __new__ precedes the customization of the object’s properties t ..read more

5/5 - (1 vote) Problem Formulation You’re given a number. How do you check if the number lies between two numbers, i.e., a numeric range? When you check if a number lies between two other numbers it returns a boolean that determines if the number is greater than or equal to the minimum number and also less than or equal to the maximum number. Here’s an example that demonstrates the problem: Example 1: Is 25 between 15 and 35?Output: TrueExample 2: Is 0.5 between 1 and 5?Output: FalseExample 3: Is 10 between 10 and 20?Output: True Let’s dive into the trivial solution next — can you f ..read more

5/5 - (1 vote) Problem Formulation: Editing very large (huge!, giant!!, massive!!!) text files, XML files, or CSV files (e.g., sizes ranging from 100 GB to 250 GB) on Windows is problematic with standard editors like Notepad, as they often crash or become unresponsive due to their inability to efficiently handle massive data loads. This necessitates the use of more robust text editing tools that can support large-scale file management without compromising on performance or functionality. Note that if you want to edit in command line, check out my related article: 5 Easy Ways to Edit a ..read more

5/5 - (1 vote) You can access the version number from the package.json file in your Node.js application by using the require() function. This is a common method for accessing metadata like version numbers from the package definition. Here’s how you can do it: Ensure that the package.json file is in the root directory of your Node.js project (or adjust the path accordingly in the code). Use the following code snippet to load the package.json file and access the version field: // Load the package.json file const packageJson = require('./package.json'); // Adjust the path if your pack ..read more

5/5 - (1 vote) Creating a Python list that counts down from 10 to 1 can be done in several efficient and interesting ways. Below, I explore ten different methods to achieve this, each with an explanation and a code snippet. Method 1: Using range() The range() function is versatile and commonly used for generating sequences of numbers. It allows you to specify a start, stop, and step. numbers = list(range(10, 0, -1)) This code uses range() to create a sequence starting from 10 and ending just before 1, decrementing by 1 each step. We convert the range to a list. Method 2: List Compre ..read more

5/5 - (1 vote) TLDR: To quickly launch an HTTP server using Python, open your terminal, navigate to the directory you want to serve, and execute the command python3 -m http.server which will start serving files over HTTP on port 8000 accessible through the default network interface. If you need to specify a different port or bind to a specific interface, you can augment the command as python3 -m http.server 8080 --bind 127.0.0.1, which uses port 8080 and restricts access to your local machine only. This method is ideal for development, testing, or sharing files within a local networ ..read more

5/5 - (1 vote) Enums (short for enumerations) are a powerful feature in Python that allows for organizing a set of symbolic names (members) bound to unique, constant values. Enums are a convenient way to associate names with constants in a clear and explicit way. Before diving into the conversion methods, let’s quickly recap the Python enum module. In this example, Color is an enumeration with three members: RED, GREEN, and BLUE, associated with the values 1, 2, and 3, respectively. MINIMAL ENUM EXAMPLE: from enum import Enum # Define an enum named Color with a few members class Co ..read more
