# Introduction The world of data science moves fast. If you are just starting your journey in 2026, you might feel like you’re trying to drink from a firehose. Between mastering Python, understanding cloud computing, and keeping up with the latest machine learning models, it is a lot to handle. But there’s a new trend …

I in my previous article, “From Code to Insights: Software Engineering Best Practices for Data Analysts”, that engineering skills and best practices can be incredibly useful for analysts and other data professionals. This is even more true now in the AI era, when we have far more opportunities to build our own analytical tools: from …
# Introduction Large language models (LLMs) have a taste for using “flowery”, sometimes overly verbose language in their responses. Ask a simple question, and chances are you may get flooded with paragraphs of overly detailed, enthusiastic, and complex prose. This usual behavior is rooted in their training, as they are optimized to be as helpful …

any time in the data engineering world, you’ve likely encountered this debate at least once. Maybe twice. Ok, probably a dozen times😉 “Should we process our data in batches or in real-time?” And if you’re anything like me, you’ve noticed that the answer usually starts with: “Well, it depends…” Which is true. It does depend. But “it …

# Introduction JSON is great for APIs, storage, and application logic. But inside large language model (LLM) pipelines, it often carries a lot of token overhead that does not add much value to the model: braces, quotes, commas, and repeated field names on every row. TOON, short for Token-Oriented Object Notation, is a newer format …

(not that long ago) when being a data scientist meant living in a notebook, tweaking hyperparameters as if your life depended on it, and in a lot of cases, the whole project did, indeed, depend on it. Do you remember those overnight grid searches? Or building feature engineering pipelines that felt more like art than …
# Introduction Anyone who has spent a fair amount of time doing data science may sooner or later learn something: the golden rule of downstream machine learning modeling, known as garbage in, garbage out (GIGO). For example, feeding a linear regression model with highly collinear data, or running ANOVA tests on heteroscedastic variances, is the …
Across 64 English authorities and six 2026 scenarios, even the strongest scenario shock was only 13% of the median uncertainty band. In plain English: the model’s assumptions moved the result less than historical forecast error did. The most aggressive challenger surge I could parameterise sits inside the noise the model has produced in past elections. …
# Introduction Every organization loves to call itself “data-driven.” It’s become the gold standard of credibility, the thing you say to shut down dissent in a meeting. But here’s something worth sitting with for a second: the phrase “according to data analytics” can come from two very different places. One is genuine curiosity. The other …

AI Agents When building an AI agent, the design choice matters. A single agent may be enough for straightforward tasks, while more complex workflows may need multiple specialised agents working together, with each one responsible for a specific part of the process, such as retrieval, writing, verification, coding, testing or review. This post explains the …
