One Byte Explainer: What is a quine?

One Byte Explainer: What is a quine?

This is a submission for DEV Computer Science Challenge v24.06.12: One Byte Explainer. Explainer The answer is "The answer is".Also called a self-replicating program, a quine is a computer program that outputs its own source code. The sentence above tries to mimic one. Its practicality can be arguable, but it's an amusing metaprogramming concept. Additional Context Here is an example in JavaScript, adapted from Dylan Beattie's beautiful talk The Art of Code: (f = () => console.log(`(f = ${f})()`))() Enter fullscreen mode Exit fullscreen mode When you run it, the output is: (f = () => console.log(`(f = ${f})()`))() Enter…

How to Deploy an Express.js App on GitHub Pages Using GitHub Actions

How to Deploy an Express.js App on GitHub Pages Using GitHub Actions

Deploying an Express.js app on GitHub Pages might sound challenging at first, but with the right tools and steps, it becomes a seamless process. GitHub Pages only supports static sites, so we need to convert our dynamic Express.js app into static files. In this article, we'll walk through the steps to achieve this using Webpack for bundling and GitHub Actions for automation. Step 1: Set Up Your Express.js App First, ensure you have an Express.js app. If you don't have one, you can create a simple app as follows: mkdir express-app cd express-app npm init -y npm install express Enter…

More on Exception Handling

More on Exception Handling

A handler for an exception is found by propagating the exception backward through a chain of method calls, starting from the current method. Java’s exception-handling model is based on three operations: declaring an exception, throwing an exception, and catching an exception, as shown in figure below. Declaring Exceptions In Java, the statement currently being executed belongs to a method. The Java interpreter invokes the main method to start executing a program. Every method must state the types of checked exceptions it might throw. This is known as declaring exceptions. Because system errors and runtime errors can happen to any code,…

Introducing Semantic Kernel

Introducing Semantic Kernel

Semantic Kernel is an open-source SDK that allows us to easily bring AI capabilities to our applications. It allows us to connect to AI services such as OpenAI and Azure OpenAI with ease. If you have worked with LangChain, Semantic Kernel is a Microsoft implementation of a project like LangChain. Semantic Kernel allows us to integrate AI functionality such as text generation, text summarization, chat completion, and image generation in our applications. In this article, we'll be exploring Semantic Kernel, unraveling its terminology, and demonstrating its capabilities by building practical applications. This article will lay the foundation of the core…

Copy Javascript Object from Safari Browser Console

Copy Javascript Object from Safari Browser Console

How to Share Console Logs from Safari as JSON There are times when we need to test something specifically on Safari and share console logs with other developers. However, Safari often renders these logs as objects that can't be copied directly as text JSON strings. I've found a workaround for this and wanted to share it. Logging Objects in Safari When you log an object in Safari, you might see something like this: Right-clicking on the object gives you a few options. Choose "Log Value" to re-log the output in the console. Getting the Variable Name This does two things:…

Unveiling URI, URL, and URN

Unveiling URI, URL, and URN

This guide provides an overview of URI, URL, and URN, explaining their differences and use cases. When developing web apps, we often need to call different web services. When configuring the communication and connection of different web services, we frequently encounter the concepts of URI, URL, and URN. Usually, users find it difficult to distinguish between them, leading to mixed or incorrect usage. In this article, we will provide examples and explain the differences between them to help everyone better understand these concepts and correctly interpret and use them when reading technical blogs, documentation, or communicating with other engineers. What…

FastAPI for Data Applications: From Concept to Creation. Part I

FastAPI for Data Applications: From Concept to Creation. Part I

In this blog post, we'll explore how to create an API using FastAPI, a modern Python framework designed for building APIs with high performance. We will create a simple API that allows users to add, update, and query items stored temporarily in memory. Alongside this, we'll discuss how you can extend this example to expose machine learning models, perform online processing in decision engines, and ensure best practices for a robust, secure API. Pre-requisites: Installation of FastAPI and Uvicorn Before diving into the code, we need to install FastAPI and Uvicorn, an ASGI server to run our application. Run the…
