Haskell
/ˈhæskəl/
noun … “Purely functional language for declarative computation.”
Haskell is a statically typed, purely Functional Programming language known for strong type inference, lazy evaluation, and immutability. Unlike imperative languages, Haskell emphasizes writing programs as expressions and function compositions, avoiding mutable state and side effects. Its type system, including algebraic data types and pattern matching, enables robust compile-time verification and expressive abstractions.
Design Patterns
/dɪˈzaɪn ˈpætərnz/
noun … “Proven templates for solving common software problems.”
Design Patterns are reusable solutions to recurring problems in software architecture and object-oriented design. They provide templates for structuring code to improve maintainability, scalability, and readability, without prescribing exact implementations. Patterns encapsulate best practices and lessons learned from experienced developers, allowing teams to communicate ideas efficiently using standardized terminology.
Key characteristics of Design Patterns include:
Actor Model
/ˈæktər ˈmɑːdəl/
noun … “Concurrency through isolated, communicating actors.”
Functional Programming
/ˈfʌŋkʃənl ˈproʊɡræmɪŋ/
noun … “Writing code as evaluations of pure functions.”
Functional Programming is a programming paradigm where computation is expressed through the evaluation of functions, emphasizing immutability, first-class functions, and declarative code. Unlike OOP, which centers on objects and state, Functional Programming avoids shared mutable state and side effects, making reasoning about code, testing, and concurrency more predictable and robust.
Object-Oriented Programming
/ˌoʊˌoʊˈpiː/
noun … “Organizing code around objects and their interactions.”
OOP, short for Object-Oriented Programming, is a programming paradigm that structures software design around objects, which encapsulate data (attributes) and behavior (methods). Each object represents a real-world or conceptual entity and interacts with other objects through well-defined interfaces. OOP emphasizes modularity, code reuse, and abstraction, making complex systems easier to design, maintain, and extend.
Key principles of OOP include:
Scala
/ˈskɑːlə/
noun … “A hybrid language blending object-oriented and functional paradigms.”
Kernel-based Virtual Machine
/ˌkeɪ viː ˈɛm/
noun … “Linux-based virtualization for running multiple OS instances.”
Abstract Syntax Tree
/ˌeɪˌɛsˈtiː/
noun … “Structural map of code for analysis and execution.”
Concurrency
/kənˈkʌrənsi/
noun … “Multiple computations overlapping in time.”
Profiling
/ˈproʊfaɪlɪŋ/
noun … “Measuring code to find performance bottlenecks.”
Profiling is the process of analyzing a program’s execution to collect data about its runtime behavior, resource usage, and performance characteristics. It is used to identify bottlenecks, inefficient algorithms, memory leaks, or excessive I/O operations. Profiling can be applied to CPU-bound, memory-bound, or I/O-bound code and is essential for optimization in software development.
