Continuing my SOLID journey, today I studied the Liskov Substitution Principle (LSP) — a principle that protects systems from fragile inheritance and unexpected behavior. 🔹 What does LSP say?If S is a subtype of T, then objects of type T should be r...

Neovim LSP Setup: nvim-lspconfig + lazy.nvim Explained

Lesson 18: SOLID 實戰篇 (3)：完結LSP、ISP 與魔王DIP

關於LSP 接下來進到L了，這裡的L指的就是里氏替換原則 (LSP , Liskov Substitution Principle)，這是許多後端工程師覺得最「抽象」的一個原則，但它其實是判斷「繼承 (Inheritance) 是否被濫用」最重要的標準。什麼是里式替換 (LSP)？「子類別 (Subclass) 必須能夠替換掉它們的父類別 (Base Class)，且程式的行為不會發生錯誤。」簡單來說，如果程式碼依賴於一個父類別（或介面），那麼隨便塞一個該父類別的「子類別」進去，程式都...

Have you ever heard of SOLID? 🤔 Let's look at the 'L: Liskov Substitution Principle (LSP)' of it.

As per the book's definition: Objects of a superclass should be replaceable with objects of its subclasses without breaking the application. It means consider the following example: class Bird { public void fly() { System.out.println(...

🚀 Troubleshooting RSVP-TE in an MPLS Core Lab (EVE-NG)

Spent some time in the lab fine-tuning RSVP-TE over an MPLS Core in EVE-NG. The goal? Build a fully operational LSP across the service provider backbone, ensuring label switching and TE constraints work as expected. But... I ran into a classic issue:...

Understanding the Language Server Protocol – Easier Code Editing Across Languages and Tools

In the past, many code editors were built just for one specific language. To provide rich and smart code editing, tight integration between the editor and the language tooling was a must. On the other hand, there were (and still are) more general-pur...
