Technologists Around the Campfire Social Audio as a Vector for Engineering Wisdom Bryan Cantrill Oxide Computer Company @bcantrill {.bsky.social, @mastodon.social}
OXIDE The radio explosion • The advent of broadcast radio mirrors the adoption of the internet: in 1923, 1% of US households owned a radio; by 1937, 75% did • This era before television was the Golden Age of Radio, when radio was the dominant means of mass communication • Essentially all mass communication – news, music, drama, comedy, sports, religion, politics, commerce – happened on radio
OXIDE Radio after television • With the advent (and explosive ubiquity!) of television, radio was forced to change: most scheduled programming went to TV • Large blocks of unscheduled content (music, sports, talk) became the norm, with each of these going through their own adaptations • Speaking very personally, radio generated the voices of my youth: Bob Martin & Larry Zimmer; Bruce Williams; Tom and Ray Magliozzi • Unlike other technological shifts, television changed radio, but it did not obviate it; why did radio continue to endure?
OXIDE The power of audio: Divided attention • Audio has an extraordinary power: unlike watching video, listening to audio allows you to easily divide your attention! • Listening to audio that does not demand your attention (i.e., background music) can help focus on cognitively intense tasks • Listening to audio that does demand your attention can help maintain alertness and energy on a repetitive task (housework, walking, driving) – and can allow you to better focus your attention on audio!
OXIDE Audio renaissance • The radio became present in every car; as more time was spent in the car, radio experienced a renaissance • e.g. NPR (started only in 1970!) became the way many got their news • Within this resurgence, a renaissance of audio storytelling in the mid 1990s led by Ira Glass and This American Life • This American Life represented a return to the Golden Era of audio in that it used audio very deliberately to tell people’s stories
OXIDE Storytelling • We are predisposed to stories, and audio is our oldest form of storytelling: we tell stories of our own and we listen to stories of others • Stories are not simply a recounting: they are captivating because they arouse our empathy (and curiosity!) – we care what happens next • Pre-literate societies used speaking and listening to convey wisdom; we are hard-wired to learn from the experiences of others • Stories are especially important for technologists!
OXIDE Dawn of podcasting • Radio was (mainly) strictly broadcast; recordings were available, but were prohibitively expensive for what amounted to a single use… • The explosion of the internet in the late 1990s gave rise to Internet radio, but it was hamstrung by proprietary formats and desktop form factors • While it was not the first portable MP3 player, Apple’s iPod had an outsized influence: podcasting was born • Importantly, podcasts were syndicated via RSS feeds
OXIDE Podcasting accelerants • Podcasts remained arguably niche for a decade, but several trends served to accelerate it into a broader mainstream… • Growing ubiquity of smartphones (starting ca. 2007) no longer demanded a dedicated MP3 player • Bluetooth enabled for wireless headphones, which more allowed for a wider range of tasks to be done while listening • Breakthrough ultra longform podcasts like Serial (2014) from This American Life alumna Sarah Koenig brought broader attention
OXIDE Starting a company podcast! • When we started Oxide in 2019, we knew that we would also start the podcast that we had always wanted: stories from engineers • On the Metal was born – and thanks to the technologists who joined us, the stories were more compelling than we could have imagined! • Many engineers who now work at Oxide were introduced to the company by listening to On the Metal • We were well into recording our second season when our plans for the podcast were interrupted...
OXIDE The pandemic • With the pandemic and lockdown in 2020, On the Metal – which we had been recording in person – went on indefinite hiatus • We assumed that we would get back to recording them, but lockdown extended longer than we had anticipated (and we had also become very busy building the product!) • But as with so much, the pandemic gave as well as took, in the form of a new twist on an old medium: social audio
OXIDE Social audio • Social audio is the use of real-time audio (that is, conversation!) within social networks on the internet • Social audio provided an outlet that a socially isolated populace craved, as demonstrated by the explosion of popularity in Clubhouse • Despite initial enthusiasm, Clubhouse also badly fumbled: iPhone-only; focused on monetization rather than value; focused on conversations with celebrities rather than peers; overrun with crypto enthusiasts • In 2021, Twitter released their social audio feature, Twitter Spaces…
OXIDE Trying Twitter Spaces • We missed audio, and Twitter Spaces seemed like a great experiment! • I convinced longtime friend and colleague Adam Leventhal to join me so I wouldn’t die alone; we held our first Twitter Space on May 3, 2021 • Twitter Spaces were immediately compelling: the dynamic of known voices plus new ones led to great conversations • Twitter Spaces had no recording feature, but Adam constructed a Rube Goldberg-esque contraption to record them • We published the recordings (YouTube + RSS) as Oxide and Friends
OXIDE From Spaces to Discord • Twitter Spaces was promising, but also maddening: many bugs and shortcomings – and not necessarily headed in the right direction • With Twitter’s new ownership, it became clear that we needed a new platform; after some experimentation, we settled on Discord • Discord is compelling in part because of its roots as true social audio (audio communication among friends) rather than celebrity worship • Discord’s stage functionality allows for new voices, easily managed • Having a concurrent text chat has been a tremendous improvement!
OXIDE Oxide and Friends • Oxide and Friends has been exactly that: hanging out with friends (old ones and new!) talking about topics that are topical or interesting to us • There have been interesting discussions – but also lots of storytelling, rants on topics of the day, predictions (and debates!) on future technologies, disagreements on corrections to pronunciation, etc. • In short, what engineers talk about! • The conversations have been well-received – but one particular group has seemed to find them especially compelling: younger engineers
OXIDE Engineering wisdom • Younger engineers are particularly drawn to Oxide and Friends because it is social audio as a vector for engineering wisdom • That is, a group of seasoned engineers expanding their circle to younger ones, showing their scars and sharing their perspectives • This shouldn’t have been surprising, but we had (accidentally!) recreated online what I had always most cherished as a younger engineer…
OXIDE The power of social audio • Social audio allows for a standing hallway track, but potentially vastly improved: open, recorded, accessible – and remote-friendly! • It allows for a team to speak in its own voice about its creations • For Oxide, this includes bringup, compliance, supply chain, debugging, system software, distributed systems – and whole lot of Rust • For some of these topics, no team has ever gone on the record with their experiences – it shines a light on broadly hidden domains • It is essential for younger engineers to see these domains!
OXIDE Social audio as a vector for engineering wisdom • Social audio presents a new vector for an age-old means for conveying our hard-won engineering wisdom – and every team can do this • There are things that happen on every engineering team that someone somewhere else will find interesting; you needn’t cater to everyone! • To be effective, social audio should be: open, recorded, and syndicated • Check out the Oxide and Friends back catalog – and join us live! • If you start your own, please let us know so we can like-and-subscribe!
