You should look at Mozilla Air. I know the site for decates, but ignored it for too long. Only after watching "The Joy of Coding - Episode 69", I realised what I was missing.
Mozilla Air is full of multimedia resources - pre-recorded shows, interviews, news snippets, tutorial videos, and features about the Mozilla community. Some of the channels are:
- After Hours - The lighter side of Mozilla. What people do after work.
- Ascend Project - The Ascend Project is a Mentorship and barrier-removing accelerator program designed to explicitly invite, include, and support adult learners in making a first technical contribution to Open Source software.
- Beer and Tell - Once a month web developers across the Mozilla community get together (in person and virtually) to share what side projects or cool stuff we've been working on. Generally this means things that aren't a direct work project.
- Engineering (highly recommend) - Engineering meetings and other engineering related video.
- How-To Videos (highly recommend) - From soft to hard skills, videos on how to do something better.
- Mozilla Project Meeting - The Weekly Project Meeting recordings.
- Privacy - Privacy Lab Recordings and other privacy-related video from Mozilla.
- Webdev Extravaganza - Webdev Extravaganzas are open to the public and serve as a gathering point for anyone in the Mozilla community who is interested in web development and what Mozilla has been doing in it. Extravaganzas are held monthly.
- Virtual Reality on the Web (highly recommend) - Bringing Virtual Reality to the Web
I left my two favorite channels for last. The first one is Livehacking, where Mike Conley and other crack programmers on the Mozilla team exterminate bugs in Firefox. Working live, without a net, they fearlessly squash bugs. The other one is Mozilla Webmaker - a Mozilla project dedicated to helping you create something amazing on the web. Their tools, events and teaching guides allow webmakers to not only create the content that makes the web great, but — perhaps more importantly — understand how the web works. With this knowledge, we can make a web without limits. They've built everything so you can see how it works, take it apart and remix it. The end goal - encourage millions of people around the world to move beyond using the web to making it.
