While LLMs, such as the popular GPT family models, are incredibly advanced, they do have their limitations. Primarily, they rely on a static set of knowledge learned during their training phase, which means they might lack specific knowledge on certain topics. One of the key concepts in working with textual data is embeddings. These are representations of text in a dense vector space, where similar items are mapped to nearby points. This technique effectively captures the semantic meaning of words, phrases, and even larger text structures like sentences and paragraphs. ...

Markdown Pages project allows you to map Markdown files to collections and easily list or read data from them. In addition to the Markdown parser, we also have the ability to parse YAML sections, where you can put a lot of useful information.

While CodeIgniter 4 itself doesn’t have a built-in queue system, I have built one which rely on the database handler. But what is a queue? It’s a system that allows you to schedule and manage background tasks or jobs to be executed in the given order. These jobs can include sending emails, processing data, generating reports, and more. Using a queue system helps offload time-consuming or resource-intensive tasks from the main application, ensuring that the application remains responsive. ...

Tags provide a way to organize content and improve the user’s experience by helping them discover related articles and navigate through a website’s content more efficiently. They are particularly useful in content-heavy websites or blogs where there’s a wide range of topics and subjects covered. This blog also uses tags system. These tags help categorize and organize content to make it more accessible and searchable. Since there was no tags library for CodeIgniter 4, I decided to write one. The codeigniter-tags is designed to work with many content types at once, so we can use it in many models. ...

Auth0 is a cloud-based service that helps developers add secure user authentication and authorization features to their applications without having to build these components from scratch. Auth0 is designed to simplify the process of implementing user authentication, including features like single sign-on (SSO), multi-factor authentication (MFA), and social login. Auth0 allows you to add basic authentication functionality very quickly by delegating it to an external platform, but we should always consider whether such a solution definitely suits us. ...
