To install OpenCV 5 on Linux reliably, first decide whether the project needs only Python, native C++ libraries, custom backends, or CUDA. On Ubuntu 24.04, for example, apt install python3-opencv still selects OpenCV 4.6.0. A command can therefore succeed while installing the wrong release for an OpenCV 5 tutorial. The 60-second selector below sends each…
, I have written quite a lot about RAG, starting with the Hitchhiker’s Guide to RAG with ChatGPT API and LangChain, and then exploring various topics related to RAG and AI, like chunking, hybrid search, reranking, contextual retrieval, and a three-part series on evaluating retrieval quality. In other words, we have covered a lot of…
, I decided I wanted to transition from data analyst to data engineer. Like many people starting out, I was overwhelmed by the sheer number of things I thought I needed to learn. Data warehouses, orchestration tools, distributed processing, streaming systems, cloud platforms, infrastructure. The list seemed endless. Instead of trying to learn everything at…
my first two articles in this series, you’ve already covered a lot of ground. You know how to create a SparkSession, load data into a DataFrame, define schemas, clean messy columns, join datasets, write Parquet files, and build simple PySpark workflows. I’ll put links to those articles in this series at the end of this…
For the first time since 2018, OpenCV has a new major version. OpenCV 5.0 arrived in June 2026, and the single biggest change for computer vision engineers is a completely rewritten DNN module with a new inference engine built for modern neural networks. Indeed, that makes it the perfect moment to answer a very practical…
