Réflexions sur l'ingénierie logicielle, l'architecture et l'art de construire.
Parcourir par sujet →A step-by-step mathematical analysis of the linear regression cost function J(w,b). We compute derivatives, find critical points w* and b*, build variation tables, and prove J is convex with a unique global minimum.
Learn how linear regression works by fitting a line to data. We cover the model f(x) = wx + b, training example notation, the slope parameter w, and the Sum of Squared Errors cost function J(w,b).
A comprehensive guide to Python tuples. Learn how to define tuples, understand how they differ from lists, read and slice elements, and use tuple unpacking for variable swapping and returning multiple values from functions.
Master Python lists from scratch. Learn indexing, internal CRUD mechanics, advanced slicing techniques, and custom sorting with lambdas and keys.
Master iteration in Python. Learn to use for loops with range, manage infinite while loops for application states, and control flow using break, continue, and for-else.
Learn how to handle conditional logic in Python. Master if-elif-else statements, write clean one-liner conditional expressions, and use structural match-case.
Learn how to use Python arithmetic, comparison, and logical operators. Master shorthand assignment syntax and the string repetition operator with clear examples.
Master Python basic data types, variables, and naming rules. Learn how dynamic typing works, declare constants, and use type checking and explicit type casting.
Go under the hood of Python! Explore its 5 key characteristics—from garbage collection to dynamic typing and learn how the interpreter executes bytecode on the CPython VM.
Learn how to install Python on Mac, Windows, or Linux using simple terminal commands and setup your environment. Write and run your first Hello World script today!
Avoid paying a fortune to the cloud just to display your portfolio. Learn how to mock API calls in Next.js to deploy complex, microservices-based resume projects for free.
In this reflection, I share how I completed both my master's thesis and engineering project on IMRAD classification. From building a 169k-sentence dataset and fine-tuning BERT models to a 98.21 percent F1 score, to launching a full microservices SaaS platform. This post details the complete technical journey.
Stop race conditions in Python! Master asyncio synchronization using Lock, Semaphore, Bounded Semaphore, Event, Condition, and Barrier in this expert guide.
Master Python asyncio: learn coroutines, async/await, the event loop, Tasks, asyncio.gather, TaskGroups (Python 3.11+), and Futures for non-blocking I/O.
