object-oriented programming

Misko Hevery's Clean Code Talk shows how to use object-oriented techniques such as polymorphism to remove repeated if and switch statements. The result is code that is easier to test, understand and maintain.

First lecture of Stanford's CS106A Programming Methodology by Mehran Sahami, giving a course overview and starting on programming. The course teaches software engineering principles using Java.

First lecture of MIT 6.00, an introductory computer science course taught in Python by Eric Grimson and John Guttag. It covers the goals of the course, what computation is, and data types, operators and variables.

Rob Pike's October 2009 Google Tech Talk introducing Go, a new experimental systems language designed for fast builds, concurrency and garbage collection. It covers the goals, syntax and type system.

Steve Jobs demos NeXTSTEP Release 3, showing the object-oriented development environment and UI that later became the basis of Mac OS X. Midway through he builds a database-backed GUI app with Interface Builder and Enterprise Objects Framework with almost no code.

Jon Bentley walks through three implementations of Hoare's Quicksort, from a dozen-line C function to a series of systematic code transformations that make the program ever simpler and more powerful. It is a Google Tech Talk on code elegance and program derivation.

Lecture 1B of MIT's 6.001 Structure and Interpretation of Computer Programs (1986) with Gerald Sussman, covering procedures, processes and the substitution model. It includes the line about the power of naming things.

Alex Martelli's Google Developers Day talk on classic design patterns (creational, structural and behavioral) and how they appear in Python. He stresses that patterns must be studied in the context of the implementing language.

Alan Kay's TED talk on teaching ideas, in which he argues the world is not what it seems and shows children learning through programming and building their own lessons with Etoys/Squeak.

Peter Norvig, then Director of Research at Google, talks at Startup School 2008 about leveraging large amounts of data and about technical challenges in Google projects such as image search. A central idea is that data can beat hand-written programming.

Joel Spolsky's 2009 Google Tech Talk on why StackOverflow was built, how it addresses the mess of searching for programming help, and the community design behind it. He also takes jabs at paywalled answer sites.
