stp2y0 CommentsNewscoding, community, development, engineering, inclusive, software

Question: in order to let "DataLoader' from torch.utils.data capable, how should I customize a dataset on my own data? Answer: basically, given a list of Paris of images and text, assigning len and get item method, then the customized dataset can be applied to DataLoader method ? is there any requirement else? Claude responds,You've captured the core concept perfectly! Let me elaborate on the key requirements and nuances of creating a custom PyTorch Dataset: `class MyCustomDataset(torch.utils.data.Dataset):def init(self, data):self.data = data # List of image-text pairs def __len__(self): return len(self.data) # Total number of samples def __getitem__(self, idx): # Return one…

My React Journey: Day 3

stp2y0 CommentsNewscode, coding, community, development, engineering, inclusive, javascript, mobile, reactnative, software

Today, I explored one of the most essential concepts in programming: Functions. Functions are a game-changer because they make code reusable, reducing the need for repetition. Let me break down what I learned: What is a Function? A function is a block of reusable code designed to perform a specific task. It has two main aspects: Declaration: This is where you create or define the function. function greet(name) { return `Hello, ${name}`; } Invocation: This is where you call the function to execute it. console.log(greet('Ayoola')); // Output: Hello, Ayoola Parameters vs. Arguments Parameters : Variables used when defining a function.…

Creating adaptive and responsive UIs in React Native

stp2y0 CommentsNewscoding, community, development, engineering, inclusive, reactnative, software, webdev

Written by Chinwike Maduabuchi✏️ Imagine developing a mobile application that looks perfect on your test device, only to discover it appears broken on users' tablets. This is a recurring challenge in both mobile and web development. As devices continue to diversify in size and capability — from compact smartphones to expansive tablets and foldables — creating interfaces that adapt seamlessly across all devices has become not just a luxury, but a necessity for success. In this guide, we'll explore different ways we can build adaptive user interfaces in React Native. We'll dive deep into the tools, techniques, and best practices…

Optimize Database Performance in Ruby on Rails and ActiveRecord

stp2y0 CommentsNewscoding, community, development, engineering, inclusive, rails, ruby, software

In Rails, we're more likely to use SQL databases than other frameworks. Unlike NoSQL databases, which can be scaled horizontally with relative ease, SQL databases like PostgreSQL or MySQL are much less amenable to easy scaling. As a result, our database usually becomes the primary bottleneck as our business grows. Although SQL databases are very efficient, as our growing customer base puts an increasing load on our servers, we begin scaling our instance counts, workers, etc. But we can't just make copies of our database for each new server we spin up. This makes optimizing database performance critical for any…

How to Create Custom Plans with “plan.md” in Goose

stp2y0 CommentsNewsai, beginners, coding, community, development, engineering, goose, inclusive, python, software

What is Goose?Goose is a developer agent that enhances software development by automating coding tasks within your terminal or IDE. Guided by your input, it intelligently analyzes your project’s needs, generates the necessary code, and implements changes autonomously. When working with Goose, having a structured way to guide its execution toward specific goals is essential. This is where the plan.md file comes in. A plan.md file allows you to define a customized plan for Goose, using flexible text formatting and the power of Jinja templating to create dynamic, reusable, and goal-oriented plans. How to Set Up GooseBefore creating your custom…

Hoisting in JS

stp2y0 CommentsNewscoding, community, development, engineering, inclusive, software

In JavaScript, we can access the variables and functions even before they are initialized or assigned a value. Look at the code below: greet(); //JavaScript console.log(x);//Undefined function greet(){ console.log("JavaScript") }; var x = 28; Enter fullscreen mode Exit fullscreen mode In many other programming languages, this would result in an error. However, in JavaScript, this code runs without any error. JavaScript executes code line by line, but before execution, memory is allocated for all variables and functions. During the two phases—Memory Creation and Code Execution—the Memory Creation Phase assigns undefined to variables(x) and stores the entire function code(greet()) in memory.…

C++ dasturlash tilida for tsikli kodni takrorlash uchun ishlatiladi. Bu tsikl ma'lum bir shart bajarilguncha kod blokini bir necha marta bajaradi. For tsikli odatda takrorlanishlar soni oldindan ma'lum bo'lganda ishlatiladi. Misol tariqasida: #include using namespace std; int main() { // 1 dan 10 gacha bo'lgan sonlarni chiqarish for (int i = 1; i <= 10; i++) { cout << i << " "; } return 0; } natija ==> 1 2 3 4 5 6 7 8 9 10 Qisqacha izoh: Boshlang'ich holat ==> int i = 1 (i o'zgaruvchisi 1 ga teng bo'lsin.) Shart ==> i <= 10 (i…

Generics in C#: Flexibility, Reusability, and Type Safety

stp2y0 CommentsNewscoding, collections, community, csharp, development, engineering, generics, inclusive, software

Meta Description:Learn how generics in C# enhance flexibility, reusability, and type safety in your code. Explore their role in collections, algorithms, and scalable application design. 1. What Are Generics? Generics allow developers to define classes, methods, and interfaces with placeholders for the type of data they will operate on. This placeholder, called a type parameter, is replaced with a specific type at runtime or compile-time. 2. Why Are Generics Necessary? Generalized Algorithms: Some algorithms, like sorting, are independent of the type of data. For example, you can sort integers, cars, or apples as long as they are comparable. Type Safety:…
