Theo de Raadt presents pledge, a new OpenBSD security mechanism that kills processes which exceed the system calls they declared they need. The talk was given late at night at Hackfest 2015.

Pat Wyatt, a veteran game programmer who worked at Blizzard and ArenaNet, speaks at HandmadeCon 2015 in a conversation with Casey Muratori. He discusses network code and architecture in games he worked on, including mistakes on Diablo and the success of Guild Wars.

Full recording of Elon Musk's January 2015 presentation and Q&A at the SpaceX Seattle office announcement. He lays out plans for a satellite constellation to provide low-latency global internet, tied to funding Mars ambitions. Pauses between questions have been edited out.

Andrei Alexandrescu's CppCon 2015 talk on handling exceptional control flow declaratively in C++. It uses scope guards with success and failure variants, built on std::uncaught_exceptions, to replace ad hoc RAII classes and rethrowing try/catch blocks.

Rick Hudson's GopherCon 2015 talk on Go 1.5's new low-latency concurrent garbage collector. It covers the motivation, performance numbers, technical challenges and why the approach fits Go.

Jafar Husain of Netflix explains at React.js Conf 2015 how Netflix runs React-style rendering without the DOM on smart TVs and game consoles. It uses a canvas-like API for performance.

Google's Amin Vahdat gives the ONS 2015 keynote on Google's datacenter networking, including its custom hardware, software-defined networking and very high bisection bandwidth.

Rob Pike presents Go Proverbs at Gopherfest 2015, a set of pithy aphorisms about Go design such as 'Clear is better than clever' and 'A little copying is better than a little dependency'.

A side-by-side edit lining up footage of the Wuppertal Schwebebahn suspended monorail filmed in 1902 and in 2015. It lets you compare how the buildings and surroundings changed over 113 years.
