Books

A clear, illustrated guide to large language models, covering key concepts and practical applications. Ideal for projects, interviews, or personal learning.

We just accept that software is inherently imperfect, that all software must contain bugs, and we design our development processes around that. But what if it were possible to write correct software? What if we could consistently develop clean, maintainable software that works perfectly, all the time? And what if it were cheaper, faster and easier to write correct code than to write the buggy variety? What then? Flawless software, delivered faster.

Not just for mathematicians and detectives! Learn the basics of logic and its many applications, including advanced testing, constraint solving, function composition, and code proofs. Over 50 exercises and 20 sample programs are included. No prior math background required!

A complete foundation for Statistics, also serving as a foundation for Data Science.
