Codexpanse Podcast

A conversation with David Kopec, Assistant Professor at Champlain College in Burlington, Vermont. David is a passionate computer science educator and writer. His latest book "Classic Computer Science Problems in Java" was just published recently. We're talking about teaching and learning programming, Swift, Dart, Python and Java, OOP and strong typing, as well as Dave's experience writing books with an established publisher as opposed to self-publishing. David's blog observationalhazard.com David's twitter @davekopec Manning had generously provided our listeners with a permanent 35% discount code for all books and other products.

Impossibilities sometimes are as exciting to mathematicians and computer scientists as possibilities. Proving something is impossible defines the limits and tames the vastness of the universe.Related links:Halting ProblemCAP TheoremTwo Generals' ProblemMusic: Intro by Air Apparent

HTTP is the foundation of modern web, and The Internet is... Well, it's simple and complicated at the same time.Let's see the big picture and clear the fog of war, rise above the minutiae and understand what the hell is going on. We will understand the following concepts:networkinternetwebweb servers and web clientsHTTP protocolHTTP requests and responsesCheck out our HTTP course at codexpanse.com.

There are a few misconceptions floating around when it comes to static typing vs. dynamic typing. Often, the difference is wrongly attributed to the way variables are allowed or disallowed to change their type on the fly. Sometimes, the difference is confused with type "strength". In this episode we'll discuss the nature of types in programming languages, and learn why static/dynamic and strong/weak are different.Related links:VIDEO: Typing: Static vs Dynamic, Weak vs. StrongStatic typing / C2 wikiType Theory / WikipediaMusic: Intro by Air Apparent

The more we learn about the nature of information, the more deep connections we discover. It seems like it is sometimes useful to see the universe as information rather than matter.In this pilot episode of Codexpanse we will discuss the implications of Claude Shannon's seminal paper "A Mathematical Theory of Communication", talk about the connection between entropy in physics and in information, and fantasize about the future of AI-based communication.Related links:A Mathematical Theory of Communication (original paper)The Misunderstood Nature of Entropy, video by PBS Space TimeWhy Information Grows: The Evolution of Order, from Atoms to Economies, book by Cesar HidalgoMusic: Intro by Air Apparent
