please note, I’ll have links to all of the videos for the talks as soon as they are available.
Links to descriptions of all of the talks can be found on the CascadiaFest 2016 page.
Day One: CSS Day
The first block started off with a talk about practical color theory. It was a good explanation for people who have maybe not taken any art classes in school (do such people exist?) with a focus on utilizing the color wheel to pick colors that work well together. The talk was focused on building a color scheme using complimentary colors, which are colors that are 180º away from each other on the color wheel. Natalya Shelburne talked about how to blend colors to make them work together, utilizing how our eyes work to trick our brains into thinking they are under the same lighting conditions. tl;dr; of that is to mix a little of each color into the other color. She then continued to build up a palette by further mixing the colors to form a neutral color, and creating tones and shades by mixing white or black into it.
Next up was Justin McDowell who talked about new CSS features that enable Bauhaus layouts in the browser. A little bit of art history thrown in a talk about CSS transforms, perspective, css grids, and a few other things. It was an interesting talk not just because the Bauhaus movement is rad as hell, but it showed how the new CSS features are enabling complex and radically different options for design.
And lastly, Miriam Suzanne talked about establishing patterns in your CSS code, focusing on how to organize your CSS code using things like Sass, naming conventions, etc. The focus of this talk was largely on building UI systems that enable a consistent API without re-inventing the wheel, and how to provide docs for your UI systems.
I skipped the second block because I was getting a headache, and needed to take a break. I am planning to watch all of the videos when they come out.
The third block started with Alice Barlett who talked about component systems and why they are important, useful, and good. She gave examples of the Financial Time’s website and why/how Origami came about. She talked about Pattern Libraries and showed off a number of them include polymer and Future Learn’s Pattern Library. She stressed the importance of documenting component systems to make them usable with a tagline of “If it’s not documented, it doesn’t exist”. I think that applies to everything, not just component systems. She recommended reading Jacob Kaplan-Moss’ Writing Great Documentation as a starting point.
Next up was James Steinbach who talked about PostCSS and the power of PostCSS. Since I’m not a frontend developer (or one who does anything beyond a little sass), it was great to hear about this powerful tool. PostCSS allows you to manipulate an AST of your CSS in interesting and crazy ways and then write the AST back out as normal CSS. How freakin’ cool is that? Like seriously, I’m in the middle of building a website for me new podcast that will be releasing in October, and I immediately added PostCSS to my build workflow for the production version that can do things like check against caniuse and fix some browser bugs in flexbox. Amazing.
I skipped out on the last talk of the block about SVG because my headache started to come back. Damn these stress headaches / allergy headaches. I’m not sure which it was, but I was having none of it, and went back to get some rest.
Someone in this block mentioned interviewing using Codility, so I want to check that out as a possible improvement over standard whiteboard interviewing.
The last block of the day were not directly related to technology. Lou Montano talked about how to learn, and be organized in your learning especially since that’s what we do, constantly, in tech. With the pace that technology changes, especially web tech, it’s important to be really good at learning. Hell, that’s why we go to conferences, right? She had a few major takeaways in the talk:
- Just-in-time learning, and necessity driven learning are what’s really required for tech.
- Experimentation and Practice are super important. Failing in experiments is meaningful.
- Make lists and chunk the learning into pieces (refer to The First 20 Hours)
- Everyone learns at their own pace. Respect the hell out of that.
Next up was Gregor Martynus. His talk was about building an inclusive and welcoming community that fosters healthy relationships, meaningful contributions, and a sense of pride and ownership from the community. He had a ton of advice, and when the video is available, go watch it because it’s worth understanding every word he says on how to make a safe, inclusive and welcoming community around your project.
The three big points for attracting a community are:
- Reach out
- Make it fun
- Keep it fun
He provides a bunch of details and examples of what each of these points are about. A few of my main takeaways where:
- Go where your contributors are
- Turn contributors into ambassadors by valuing them and being gracious of all of their contributions
- Host Events like Hackathons
- Making it fun should be for everyone, not just a select group of people
- Creating a safe space is of the utmost importance
- Choose a license early
- Optimize for contributors
I literally took 3 pages of notes from Gregor’s talk, and suggest you all watch it when it’s available.
The last talk of the day was by Alan Stearns of Adobe fame, and he impressed on us the responsibility of the future of CSS is in our hands, and we should take an active part in driving that. The main things he asked us ,as users of the web, to do is to make noise when something breaks, write about what we try and do, and file browser bugs when things are broken. It was a good, impassioned plea for people to be more active.
Day Two - Browser Day
Rebecca Murphey gave a talk about working with legacy apps, or as she likes to call them “vintage” apps, which is a freakin’ rad term. She talked about her experience migrating a website from a disheveled mess of jQuery towards more modern approaches. She talked about centralizing the state of the app, a la Redux, the importance of things like guardrails (linting & tests) to ensure nothing breaks, and how instrumentation is so critical to knowing what’s happening in the browser.
She talked a little about frameworks and recommended reading Tessa Thornton’s How to learn web frameworks
Afterwards Nolan Lawson laid down some knowledge about service and web workers, and the main take away is start using them. All up-level browsers have them, and there is a polyfill that falls back to running in the main thread if they aren’t supported. He provided lots of good examples of why, using animated gifs of Kirby. It’s amazing how many supposedly async things block to the UI thread and stop animated gifs.
Lastly, Seth Samuel gave us a quick introduction to doing arbitrary computation on the GPU, and the main
takeaway is that for small problems, using the GPU has too much overhead, but for your data is large, and
you can pay the overhead of calling
canvas.getImageData, then it might be worth it, but you’ll need to
develop a heuristic for your specific problem for when to do it in one place or the other.
More headache fun, so I missed this one. I’ve heard good things about all three talks, so I’m planning to watch them when they are available on video.
Rachel White told us about her cat, Rick, and his amazing adventures in her apartment while giving us an introduction to game programming using Phaser. She’s inspired me to create Cheese Vikings so if anyone is interested in making a Free-to-play HTML5 game with me, let me know.
Thomas Wilburn from the Seattle Times gave us an inside look at how they use custom elements across the org for production websites that get a ton of hits daily. He showed off how you can make custom elements approachable, and easy for content creators to use. Want a leaflet map without all of the annoying boilerplate html? Here’s a custom element for that (at least if you work at the Seattle Times). The power of custom elements makes it obvious why it’s a great technology that we should all start using.
The last block of the day was skipped because my headache would just not freakin’ quit, but I’ve heard good things about Dale Bustad’s talk about HTTP/2 Server Push as well as Marcy Sutton’s Where in the Stack is Carmen Sanfrancisco.
Day Three - Server Day
I can’t go into too many details here because, well, I was in the green room for most of it, but Mariko Kosaka started off the day with talking about Computer Vision and running CV in web workers to get it off the main thread. She gave a great intro to CV and how to do interesting things with CV.
Next up was Pawel Szymczykowsi talking about mobile app testing using a tapster robot and a little CV. While Mariko concentrated on experimentation and play in CV, Pawel’s talk about all about practical application . He showed us how to use template match to find buttons on a mobile screen and press it with a stylus.
Oops, totally missed that because I was too busy talking to people and decompressing from giving my talk.
Brock Whitten started up the block with a talk about latency and how to remove latency by utilizing caching in various forms to reduce the need for higher-cost options. Caching in memory is faster than caching on a local disk which is faster than caching in a database. It was a practical approach to achieving greater throughput on web service.
Next up was Nwokedi Idika who talked about the darknet, specifically Tor and how it works. It was a great explanation and description of how Tor functions and provides anonymity from bad actors (e.g. hackers, gov’ts, etc). I enjoyed the fact that he replaced the standard crypto actors with pop culture icons like Adele, Beyonce, Charlie Murphy (Eddie’s brother), Drake, and Eddie Murphy.
Keeping with the theme of crypto, Bill Automata talked about what’s in the node crypto module, and the history of the US government meddling in crypto from the never beginning. He also talked about why crypto should be accessible to all, and why we should lobby for strong encryption and not allow the government to weaken encryption with things like law enforcement keys.
Media and Other things
Pictures this year were crowdsourced, so I’ll be keeping an updated list of media and such here.
