Data Science Roadmap 2026: A Complete Step-by-Step Guide
A data science roadmap in dependency order, from Python and SQL through cleaning, statistics and honest model evaluation to communicating results, with an exit test at every stage and one dataset that carries through the whole path.
What Is Generative AI? A Complete Beginner's Guide
What generative AI is, in plain language: how language models produce text one token at a time (shown with a tiny runnable model), how chat models are trained, how image models differ, what the technology is reliable for, and why it confabulates.
Learn Python from Scratch: A Complete 2026 Roadmap
How to learn Python from zero: install a current version (including the new Windows install manager), then work through seven stages, from values and loops to files, virtual environments, classes and tests, each ending with a small program you should be able to write on your own.

Medallion Architecture: Bronze, Silver and Gold Layers
The medallion architecture explained by building it: bronze as raw data exactly as it arrived, silver as validated and enriched rows, a quarantine table that keeps every rejected row with its reason, gold shaped for one dashboard, a reconciliation that bronze equals silver plus quarantine, and the mistakes teams make.
Copy Activity in Azure Data Factory: A Practical Guide
The Copy activity is the workhorse of Azure Data Factory. This guide explains what it does in three steps, the formats and stores it handles, column mapping, the sink write behaviours, insert, pre-copy script and upsert, compared on a real table across three runs, fault tolerance, staging, and reading the output.
Pub/Sub Explained: Messaging and Streaming on GCP
Pub/Sub carries messages from the systems that produce events to the systems that use them, without either knowing about the other. This guide explains topics, subscriptions and the three delivery types, models why a message can arrive more than once, and covers ordering, dead-letter topics, retention and cost.
AWS Glue Tutorial: Serverless ETL on AWS
A beginner's tutorial on AWS Glue, the serverless ETL service: what each component does, the catalog, crawlers, jobs, triggers and workflows, how they fit into one pipeline, a crawler, job and nightly schedule defined in code with boto3, how billing works, and the settings to get right on day one.
Salary Negotiation: How to Get Paid What You're Worth
In negotiation experiments, whoever made the first offer usually got the better deal, and first offers strongly predicted the final price. The same research shows how to neutralise an anchor: focus on your own target and alternatives. This guide turns those findings into a practical plan for negotiating a job offer.
Deep Learning Guide: Neural Networks Explained Simply
Neural networks explained by building one: a tiny network written in NumPy learns a problem no straight line can solve, showing layers, activation functions, the loss, backpropagation and gradient descent step by step. Then the same model in a few lines of PyTorch, and when deep learning is and is not the right tool.
