Opening Remarks

09:45 – 10:30

Remy Sharp – Using a Modern Web to Recreate 1980s Horribly Slow and Loud Loading Screens

These days people chase the dream of high performance, fast loading slick web sites. But in the 1980s computers were ugly, slow and loud: let’s make that instead!

The first generation of home computers launched a movement of developers and hackers across the world. But to start your app, you had to load a tape (a really old usb-type-thing), press play, and patiently wait for the screech of the program to load (akin to listening to a fax machine).

Why invest time in building fast website, when we can have fun building slow old retro machines using JavaScript? The end result is a mix of Web Audio, canvas API, cameras, audio jacks, binary, typed arrays, blobs, history of computing and a lot of questionable JavaScript.

10:30 – 11:15

Nadieh Bremer - Data Sketches: A Year of Exotic Data Visualizations

Data Sketches was a year-plus long collaboration between Nadieh Bremer and Shirley Wu, both freelancing data visualisation designers. Almost every month they chose a topic and visualised it in an overly-elaborate and geeky manner. But besides sharing the end result, they also wrote extensively about the creation process.

In this talk, Nadieh will share her most important lessons learned in the fundamental areas of data, sketching & coding. About how some months became favourites, what mistakes were made, and how they were overcome. She’ll highlight that many visualizations had humble, ugly duckling beginnings, but that through many (embarrassing) iterations they were turned into unique and, hopefully, compelling results.

11:15 – 11:45

Break (30 minutes)

11:45 — 12:30

Sharon Steed - Creating a Culture of Empathy

The most successful endeavours all follow the same general trajectory: a decent idea executed flawlessly by a cohesive team of hard workers. No matter the project, everything can be achieved following this general guideline. But the exact thing that can create global companies, solve impossible problems, and bring ideas to life is also the same reason why so many companies fail. That thing is us. People. But when we’re at our best, there isn’t anything we can’t do. So how do we optimise collaboration? How do we work better together even if we don’t see eye to eye with everyone on our teams? And how do we create a culture of empathy when all we can see about everyone around us is our differences?

Sharon Steed explores empathy in an unusual way: from the perspective of a stutterer. Sharon explains what empathy is (and what it isn’t) and gives you the tools you need to create a culture of empathy on your team.

12:30 — 13:15

Andrew Betts - Making less of the web with feature policy

The web platform has seen a decade of furious expansion, with websites now able to access USB, vibration, bluetooth, and geolocation, as well as store huge amounts of data on end user devices, trigger background sync and notifications, and even get paid from users' digital wallets.

But with this expansion has come an increased scope for attacks, costly mistakes and performance regressions.  Feature policy is a new feature designed to actually disable or limit features of the platform.  With a feature policy, developers can solve performance issues, improve security, police their development team's best practices, and even stop third party scripts from misbehaving. All with one new HTTP header.

13:15 – 14:30

Lunch (1 hour 15 minutes)

14:30 – 15:15

Lightning Talks

A series of lightning talks covering a variety of topics.

15:15 – 16:00

Sarah Drasner - Future of Animation

We talk a lot about how to animate on the web, and what's possible in browsers today, but where is animation heading? In this talk, we'll start with some bleeding edge techniques such as native-like page transitions with client side rendering, but then we'll push it further.

The intersection of health and animation with biofeedback sensors, the future of 3d in the browser complete with interviews with people who are writing these specs... this talk will show that in terms of animation on the web, we're just getting started.

16:00 – 16:45

Tim Kadlec - TBC

Talk summary coming soon.

The nearest bus stops to the venue are on Boar Lane. There are frequent buses to the following stops:


A taxi from a Leeds suburb will cost you anything from £6 – £20. White taxis will cost slightly more. Amber Cars are a well known and respected Leeds taxi company, however you will need to pre-book. You can easily get an Uber to the venue from most parts of Leeds.


Whilst it might be more convenient to drive to the venue, the cost of all day parking may outweigh that convenience. The nearest car parks can be found on Swinegate and Butts Ct. CitiPark Leeds Dock is further away but may be cheaper than the more central options.
