A 2012 Fortune dinner debate between Peter Thiel and Eric Schmidt over whether technological progress is healthy or stalling and whether Google can still innovate.

Eben Moglen's re:publica 2012 talk argues that media which spy on and data-mine the public threaten freedom of thought, and that free technology and free culture are needed to protect it.

Yehuda Katz's Railsberry 2012 talk on why Rails is hard to learn and use. He explains that the framework's many features reflect real complexity in web applications that newcomers do not yet see.

A dotJS 2012 conference talk by Fat (of Twitter Bootstrap fame) on what open source really means and why maintainers feel guilty about it. It covers the obligations, expectations and burnout that come with releasing popular open source software, delivered with humor.

Joel Spolsky, founder of Fog Creek Software and StackExchange, speaks at Y Combinator's Startup School in 2012. He shares his perspective on building startups.

Matt Wynne's GoRuCo 2012 talk on why Rails apps get hard to change as they grow, and how a ports-and-adapters hexagonal architecture separates application logic from the framework.

Chandler Carruth's GoingNative 2012 talk on Clang, covering how the compiler helps defend C++ code from mistakes. It makes the case for Clang's diagnostics and tooling.

Brian Leroux's dotJS 2012 talk WTFJS is a quick, humorous tour of JavaScript's odd behaviors and quirks.

A fireside Q&A with the Go team (Pike, Thompson, Griesemer and others) at Google I/O 2012. They answer audience questions about Go's design, goals, garbage collection plans and future.

Gary Bernhardt argues that software history moves in reactions to earlier tools, and that new tools are not simply better in every way. He distinguishes capability (what a tool allows) from suitability (what it fits), and warns against repeating past mistaken reactions.

Kalman Reti, one of the last Symbolics developers, gives a roughly hour-long talk on Symbolics Lisp machines. It covers the machines and their environment from an insider's perspective.

Lieutenant General Mark Hertling gives a TEDx talk arguing that obesity and poor youth fitness are a national security problem because too few young Americans can meet military physical requirements.

Karen Sandler's keynote at Linux.conf.au 2012 on the software running inside medical devices such as her own pacemaker-defibrillator. She discusses the difficulty of learning what code runs in life-sustaining devices and why open source matters there.

Dave Chinner's linux.conf.au 2012 talk on XFS scalability, covering pain points with large numbers of files and complex metadata, and the work to fix XFS metadata performance.

Matthew Garrett's linux.conf.au 2012 talk covers EFI and UEFI from the Linux point of view: why the PC BIOS was bad, what EFI changes, the issues it brings, and Secure Boot.

Rusty Russell and Matt Evans examine why Unix utilities like ls and cat grew from a few kilobytes to over a hundred kilobytes. They take apart common tools to see where the growth comes from.

Jim Weirich's RubyConf 2012 talk derives the Y combinator step by step, live-coding in Ruby lambdas. It builds up an understanding of functional programming and lambda calculus from first principles.

Bret Victor's talk at CUSEC 2012 in which he argues that creators need immediate feedback and should organize their work around a guiding principle. He demonstrates live-coding and animation tools that show results as you type, and describes his own principle that creators must see what they are making.

Rich Hickey's JaxConf 2012 keynote examines what values are and why immutable values matter as information systems grow more complex and data gets bigger. It contrasts places with values and builds the case for immutability.

Gary Bernhardt's RubyConf 2012 talk on testing in isolation without mocking everything. It goes through behavior versus data, mutation versus immutability, and how a functional core with an imperative shell yields natural isolation and parallelism.

Jack Diederich's PyCon 2012 talk argues that classes are overused in Python and walks through real code, refactoring away unnecessary classes, exceptions and modules. It popularized the heuristic that a class with two methods, one being __init__, should be a function.

Paul Graham's keynote at PyCon 2012, in which he talks about startup ideas and what kinds of companies are likely to matter in the future. He discusses ideas such as a better email client and a search engine for hackers, and argues for looking back at the present from the future.

Christopher Domas presents his Cantor Dust tool at Derbycon 2012, a 3D visual approach to reverse engineering binaries by visualizing their structure dynamically.

Jason Scott's DerbyCon 2012 talk on rescuing the Prince of Persia source code from old floppy disks, working with the game's author Jordan Mechner. It is a story of digital archaeology and recovering data from ancient media.

Rich Hickey, creator of Clojure and designer of Datomic, gives a JaxConf 2012 talk that takes apart traditional database architecture. He presents a different way to think about databases and explains the reasoning behind Datomic's fact-based design.
