Science Fictional User Interfaces

This week at the Strata Data Conference, in London, Mars and I gave a talk on Science Fictional User Interfaces. It was a very enjoyable talk to prepare, and we were really thrilled to be given a slot at such a technical data-focused conference as Strata, to effectively rant about how great science-fiction is, and how everyone should watch, read, and play more sci-fi.

This post serves to provide some links to resources that we mentioned in the presentation, or that we think you’d find useful if you enjoyed the presentation. We’ll also post a video of the talk here, once it is available (usually a few weeks!)

If you’re interested in reading more about this topic, there’s two amazing books that cover similar ground:

There’s also a range of books that take a different angle on a similar topic:

  • Designing Agentive Technology (Christopher Noessel) — available from O’Reilly’s Learning Platform, Rosenfeld Media, and Amazon
  • Speculative Everything (Anthony Dunne and Fiona Raby) — available from The MIT Press and Amazon
  • Typeset in the Future: Typography and Design in Science Fiction Movies (Dave Addey) — available from Amazon
  • Extrapolation Factory Operator’s Manual (Elliott P. Montgomery and Chris Woebken) — available from Amazon

And there’s some interesting papers and academic articles we think you might be interested in, if you enjoyed our talk:

  • Hopes and fears for intelligent machines in fiction and reality (Stephen Cave and Kanta Dihal) — available from Nature Machine Intelligence
  • Long-Term Trends in the Public Perception of Artificial Intelligence (Ethan Fast and Eric Horvitz) — available from arXiv
  • “Scary Robots”: Examining Public Responses to AI (Stephen Cave, Kate Coughland, and Kanta Dihal) — available from AIES Conference

Software Architecture NYC 2019

The O’Reilly Software Architecture Conference 2019 (SACon) just wrapped up in New York City, and I was privileged enough to attend as a speaker with my friend and colleague, Tim, and partner and colleague, Mars. Together, we presented a session called Entity-Component-Systems and you: they’re not just for games anymore, and Tim and I did a book signing for our recent title Learning Swift (3rd edition), as well as a Meet the Experts session.I was initially quite sceptical of the SACon, because the idea of an event based on ‘software architecture’ conjured up images of very dry sessions on traditional, serious enterprise architecture, presented by uninspired, uninspiring people. As it turns out software architects, and those who attend software architecture conferences, are incredibly passionate, interesting people, who are the very opposite of the straight-laced faceless people I imagined.

SACon was a melting-pot of interesting ideas, framed around the discussion of software architecture as a profession. O’Reilly’s conferences are always polished, well, run and all that good stuff (disclaimer: as might be obvious, O’Reilly is my publisher), but the attendees and speakers are what makes any conference shine. This conference definitely shone.

All the sessions that I attended were excellent, but the highlights of the conference for me were definitely the following talks:

The ‘hallway track’ was also exceptional, and we had some fantastic conversations with attendees on topics ranging from the rise of the Rust programming language to the use of ECS in non-video games to the merits of the Swift programming language to designing video game engines, and beyond.

Tim and I really enjoyed our book signing, and found ourselves face-to-face with one of the biggest queues we’ve ever had for a book signing, and had some excellent conversations with developers, architects, and team leads who were excited to learn Swift from our book, or share it with their teams back home.

Our ECS talk went well! We had a packed room (which was also one of the most palatial conference halls we’ve ever spoken in!) and got 5-star reviews with great feedback.

If you’re interested, you’ll find the slides from our talk on ECS are available via the conference website. You can also find a video embedded below, or on YouTube, or O’Reilly’s Learning Platform. (if you have an O’Reilly Learning Platform subscription, we strongly recommend watching it there!)

There’s some follow-up resource we want to share with attendees of our talk. We hope you find them useful!

I’m excited to return to a future SACon! The good news is there’s lots of them to choose from! San Jose is coming, as is Berlin!

OSCON 2018 Recap

A few weeks ago I attended, and spoke at, my 10th OSCON conference. I regularly say that OSCON is my favourite big conference, and every time I attend I’m reminded why I love it, and how much I love it: OSCON is a fun, relaxed, and very approachable place where companies and people involved in open source as contributors, consumers, and users, interface, work with, and have fun with each other. It’s unique in perspective, content, and value. And it’s super engaging everywhere from the lunch hall to the hallway to the sessions and in between. You should go, if you get the opportunity (O’Reilly runs a wonderful diversity and inclusion program, which make me able to help you make it along!)

This year was OSCONs 20-year celebration event! 🎉 If you have a Safari subscription, you can check out the videos from the event here. There’s also a collection of keynotes and interviews from the event on the O’Reilly Media YouTube channel.

On the Monday, Tim, Jon, and I presented a 3 hour session on Open source game development with Godot. Godot is an amazingly polished, and entirely open source, game development engine; Godot is a project of the Software Freedom Conservancy, and is aggressively competitive against the big commercial engines, like Unity and Unreal. I largely led this tutorial, supported by Tim and Jon. We got great feedback from our attendees, and had a full house. I’ll post the material from the workshop in the coming week.

On Tuesday, Tim, Jon, and I presented a 3 hour session on Machine overlord and you: Building AI on iOS with open source tools. We covered everything from CoreML, to Vision, to Apple’s Turi Create Python libraries. Our attendees loved it, and gave us great feedback; it was a fun precursor to our new book, Practical AI with Swift (more on that soon!) You can find the material from this OSCON session right here.

On Tuesday night, I stepped way, way out of my comfort zone and presented a 5 minute Ignite talk on The realities of weightloss. This talk was based on a seed of an idea that Mars had, which I’d taken and run with in a slightly different direction (with her permission). It seemed to resonate with the audience, and I got a lot of thanks, and hugs, from people afterwards. ❤️

The next day, Wednesday, saw us doing our traditional book signing (for the latest Learning Swift) in the O’Reilly Media booth of the expo. We had a huge line of people, and signed for about 45 minutes. It was great fun! The O’Reilly staff treat us like royalty, which always makes us feel very special.

On Thursday, in the second-last slot of OSCON 2018, Tim and I teamed up with Mars to deliver an entirely-live coded talk on Learning Swift with Playgrounds. Mars wrote all the examples, designed the flow, and really got thrown in the deep end—and she totally nailed it! Tim provided an excellent narration of proceedings, as Mars live-coded her way through the demos (with Xcode crashing, as is custom!) We got many fabulous reviews, with the talk getting a 4.9/5 ⭐️ average. We were thrilled. You can find some notes here, and the fabulous Playground that Mars wrote here on GitHub.

Our friends, VM, Josh, and Paul, also delivered well-received, and awesome talks.

We really love working O’Reilly, particularly our amazing editor, Rachel Roumeliotis, who has risen the ranks of the company while we’ve been working with her (absolutely no connection to us working with her!) and is now a VP of Content Strategy.

We’re doing a bunch of great projects with O’Reilly over the coming year or two, including finishing up a new edition of our iOS Swift Game Development Cookbook, as well as a new Unity Game Development Cookbook, a Head First Swift book, and a brand new title, Practical AI with Swift. More updates on all of these soon!

Our latest edition of Learning Swift is available, and getting a bunch of great reviews, and our Mobile Game Development with Unity remains a fabulous guide to building games with Unity. Check them out?

I’ll leave you with one of my favourite tweets of the event, which someone sent following our Learning Swift 3rd Edition book signing:I can’t wait for next year’s OSCON: July 15-18, again back in Portland!
