Beyond multi-core parallelism: faster Mandelbrot with SIMD

What do you do when computation is too expensive? Recently I’ve had a brilliant business idea: Mandelbrot-as-a-Service! Instead of companies calculating their own fractals, I will do it for them, freshly calculated in the cloud, with no work on their part. And by using cloud computing, I will be able to scale to the no-doubt vast number of customers who will be paying for my ingenious new service. I have two goals: Speeding up results: The faster I can return […]

Differences Between Python’s Mutable and Immutable Types

As a Python developer, you’ll have to deal with mutable and immutable objects sooner or later. Mutable objects are those that allow you to change their value or data in place without affecting the object’s identity. In contrast, immutable objects don’t allow this kind of operation. You’ll just have the option of creating new objects of the same type with different values. In Python, mutability is a characteristic that may profoundly influence your decision when choosing which data type to […]

Data Formulator: Exploring how AI can help analysts create rich data visualizations 

Transforming raw data into meaningful visuals, such as charts, is key to uncovering hidden trends and valuable insights, but even with advances in AI-powered tools, this process remains complex. Integrating AI into the iterative nature of the data visualization process is particularly challenging, as data analysts often struggle to describe complicated tasks in a single text prompt while lacking the direct control of traditional tools. This highlights the need for smarter, more intuitive solutions that combine AI’s
