Lisa's notes: musings on daily life, work, study, personal growth, and casual reflections.
This learning note walks through a complete Java Car class example, explaining its instance fields (brand, color, speed, id), a static count field, a parameterized constructor that auto‑increments the count, and accessor methods that illustrate core object‑oriented concepts.
The article traces the historical roots of humanoid robots, outlines safety protocols like Asimov's Three Laws, categorises robot generations and control types, dissects the upstream‑downstream supply chain with component cost breakdowns, examines manufacturing processes, showcases key application scenarios, and analyses emerging business models and challenges in the fast‑growing robotics market.
This tutorial demonstrates how to delete elements from Python lists by using the pop() method with optional index, the remove() method for specific values, and the clear() method to empty the list, illustrated with concrete examples and output results.
This tutorial explains how the Java this keyword references the current object, showing its use for accessing shadowed member variables and invoking other constructors through clear code examples such as Point and Rectangle classes.
This tutorial walks through Java member methods, covering return statement syntax, proper use of getters and setters, the static modifier for class members, and the final keyword for classes, variables, and methods, with concrete code examples and explanations.
The article examines two frequent project‑management problems—ever‑changing requirements and internal team friction—illustrates each with real‑world cases, and shows how strict change‑control procedures and daily stand‑ups can cut informal requests by 50% and double iteration speed.
This tutorial walks through the fundamentals of Java objects, covering declaration, instantiation, referencing, practical code examples—including a HelloTest class and a Point/Rectangle demo—and explains Java's automatic garbage collection and manual cleanup techniques.
The article outlines practical steps for project managers and team members to allocate time across multiple projects, emphasizing clear goals, weekly task breakdowns, resource matching, regular progress checks, effective communication, prioritization, and reusable modules to improve efficiency and reduce risk.
This learning note demonstrates essential Python list and string techniques, including list concatenation with '+', membership testing using 'in' and 'not in', and various slicing methods, all illustrated with concrete code snippets and their output.
This tutorial note walks through Python variables, demonstrates how lists can store multiple heterogeneous items, explains list declaration, indexing, modification, and shows two ways to iterate over a list with concrete code examples and their output.
