What is abstraction in computer programming? Explanations and code examples in Clojure and Python.

Last night I received an e-mail in which one of my visitors asked me a few questions after reading the post about parsing phone numbers in Clojure. The question was seemingly simple and concerned a technical detail of software construction, but in reality the reader touched on a very important subject that I had been pondering years ago, and I decided to summarise it here.

Every couple of years, there’s an increase in devices that enable individuals to measure the bioelectrical activity of their brains at home. These devices exploit the occurrence of fluctuating brain wave frequencies, which vary according to the user’s psychophysical state. Driven by a pandemic-induced fondness for my residence, I decided to purchase one of these gadgets. After several weeks, I sought to offer a subjective review of the chosen model and conduct an experiment using raw data.

Attacks that rely on setting up fake update servers are not as difficult to carry out as one might think. The main reasons are administrators’ carelessness and the absence of robust version-publishing processes, although occasionally we see astonishing attack vectors that are hard to anticipate.
