Kopec Explains Software

Digital images can be broadly categorized into two kinds: bitmap and vector. In this episode we provide the listener a general understanding of how both bitmap and vector images work. We start with the basics, by explaining pixels, but then we talk about a standard color model, and some specific file formats that most people are familiar with. We finish our discussion by talking about smartphone cameras, image manipulation software, and how images work together to make videos. Note: In this episode we used the term "graphics card" generically. We could have more accurately said Graphics Processing Unit (GPU) to include embedded GPUs as exist in most devices.

Encryption enables online payment, secure communication, identity verification, and so much more. In this episode we discuss what encryption is, what it does for us, and we go over some of the different types of encryption. We explain the purpose of a key, and try to provide an intuitive understanding of public key cryptography. We also discuss some practical tips around passwords. Finally, we talk about some of the public policy debates surrounding encryption. Note that in this episode we refer to cryptographic hash functions as "one-way encryption" to try to simplify the discussion. Follow us on Twitter @KopecExplains.

In 1975, the Altair 8800 powered by the Intel 8080 ignited the personal computer revolution. In this episode, we discuss the pivotal forces that made computers accessible to normal people, and enabled the creation of companies like Microsoft and Apple. We discuss some of the major computers of the late 1970s and some of the important software products. We cover the period of 1975-1980. This episode is not meant to be an exhaustive history, but instead a good general overview. We couldn’t cover every computer, software product, or important person in the PC revolution. But we hope we excited listeners to explore more.

Artificial Intelligence is enabling exciting new computing applications, but many people don’t really understand what it is. In this episode we give AI a broad definition, explain the difference between strong AI and weak AI, and delve into some of the many sub-disciplines that fall under its umbrella. We provide a general sense of machine learning by touching on a few of its approaches including artificial neural networks, clustering, and linear regression. We also briefly dive into older AI techniques like expert systems and adversarial search. We use chess as an example to talk about different AI approaches. Follow us on Twitter @KopecExplains.

Programming languages are what we use to communicate ideas in computing. Software is written in a programming language and most people have a vague sense of what a programming language looks like. In this episode we explain a programming language’s purpose and we categorize programming languages into various paradigms. We discuss some of the characteristics that make one programming language distinctive from another. At the end we dispense some advice for those interested in learning their first programming language. Follow us on Twitter @KopecExplains.
