JavaScript Execution Context!

stp2y0 CommentsNewscoding, community, development, engineering, inclusive, javascript, programming, software, webdev

In JavaScript, when a function is defined and later invoked, it creates an abstract container known as an execution context. This execution context holds several key components: the variables declared within the function, any nested functions, and the lexical environment. Together, these elements define the operational environment for the function's execution. Source link lol

Pre-training, Fine-tuning, and Transfer learning. To make these ideas more relatable, let’s use a real-world analogy

stp2y0 CommentsNewscoding, community, development, engineering, finetuning, inclusive, pretraining, software, transferlearning

Pre-training is like the education students receive in school. Just as teachers train students in a broad range of subjects, a model is pre-trained on a vast amount of data, learning general knowledge. This foundational learning requires significant effort and resources, similar to the years of schooling and the dedication of many teachers. Fine-tuning occurs after students graduate from school and choose a specialized field, such as medicine, engineering, or law. In this phase, they receive targeted training in their chosen domain, much like how a pre-trained model is fine-tuned for specific tasks. Before this specialization, the students (or the…

For my third widget, I designed an image card with overlay text, focusing on both visual appeal and user experience. Here are the key UX ideas I implemented: Rounded Corners: Used rounded-xl to soften the edges, making the card feel more modern and approachable. Shadow Effect: Added shadow-xl shadow-purple-500 to create depth, giving the card a subtle 3D effect that makes it stand out. Hover Interaction: Implemented hover:scale-105 to add a slight zoom effect on hover, enhancing interactivity and making the card more engaging. Text Readability: Applied text-2xl font-bold tracking-tight for the title and font-light leading-relaxed for the body text…

An (Im)mutable Shopping List for a Delicious Pesto Pasta

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

Pesto pasta is proof that G-d exists There are few things in life that give me more pleasure than a heaping helping of fresh pesto over homemade Capellini (Angel Hair). I'm a bonafide foodie - especially when it comes to Italian cuisine - and am always trying more complex recipes, but the simplicity and enjoyment of such a minimalist dish never ceases to satisfy. If I had the (mis)fortune of choosing a last meal it would be a tough decision between sushi and pesto over pasta, but I still think pesto pasta wins out in the end. All this talk…

Why we use snake_case for variables and camelCase for functions

stp2y0 CommentsNewscoding, community, development, engineering, fullstack, inclusive, javascript, software, webdev

To be less stressed, and therefor better programmers, we have to do our best to free our code from bullshit that makes it a hard to maintain, and onboard new devs-to. We use the same name for database fields, JSON property names returned from an API, the HTML form field name attributes, and finally, the Javascript variable names that contain those database-originating values. Naming your data exactly the same in all layers of the stack frees you from having to keep a mental mapping of what is what. Discipline yourself to enforce this rule, and you will be a less…

RAG (Retrieval-Augmented Generation) is all the rage. And there's a good reason why. Like so many others, I instinctively felt an air of excitement at the beginning of the internet. The Browser Wars, Java vs Mocha. And then again in 2007 when the iPhone led a paradigm shift to how, where, and when we consume media. Just as I do now, In the rapidly advancing field of AI, Retrieval-Augmented Generation (RAG) has become a crucial technique, enhancing the capabilities of large language models by integrating external knowledge sources. By leveraging RAG, you can build chatbots that generate responses informed by…

How to write better Typescript code? 10 advanced tips

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

In this article, we’re going to dive into 10 advanced tips to elevate your TypeScript coding skills. These tips go beyond the basics, offering insights and techniques to help you write more efficient, maintainable, and type-safe code. #1 Optional Chaining (?.) Optional chaining allows you to safely access nested properties or methods without worrying about null or undefined values. It short-circuits the evaluation if any intermediate property is null or undefined, preventing runtime errors. const user = { name: 'Piotr', address: { city: 'Warsaw', postalCode: '00-240' } }; const postalCode = user.address?.postalCode; console.log(postalCode); // 00-240 const invalidCode = user.address?.postalCode?.toLowerCase(); console.log(invalidCode);…
