Talk 1 - Web Crypto
The kickoff talk this year was pretty awesome. It was “Dodging Web Crypto API Landmines” by Ernie Turner (@erniewturner). He went over the new
window.crypto API, how to use it, what the caveats are, and the happy-path of using to develop a in browser encryption / decryption application.
He posted his slides on twitter after the talk.
At this point the conference split into two tracks, one with an intro to Vue.js and the other with two talks. I went with the two talks while Linda went to the Vue workshop.
Talk 3 - Lean Coffee Talks.
The speaker for this slot had a family emergency and could not make it. Instead the stand-in conducted what were referred to as “Lean Coffee Talks”. Essentially each table wrote down a number of talks, the table voted on which ones they wanted, and cycled through discussions of those talk subjects. I sat with much of the Scala (not to be confused with the programming language) team, and the few topics we went on were:
- How do you decide on a Technology or Framework for a Team
Lunch was excellent, they had plenty of food, and (good for me) low carb options. It was also an hour and half, so there was plenty of time to catch up, talk with a lot of the developers and ex-coworkers I had seen walking around the conference.
The early afternoon session was split between a Pair Programming and TDD in Jest, or two more talks. I once again went with the talks.
Talk 4 - Full Stack Graph Applications using the GRAND Stack.
This talk was mostly a marketing pitch for Neo4j, as the GRAND Stack uses Neo4j as the backend (and was conceived by Neo4j engineers.) The Grand Stack, for the lazy, is
- Neo4J Database
The general concept is with a React + apollo frontend, along with a GraphQL + Apollo
- Neo4j backend, you can solve certain problems pretty easily. While I’m a big fan of GraphQL, I didn’t see a super compelling reason why throwing out relational databases would be a huge benefit in most cases.
The cases he covered in the presentation were very cool, namely mapping out twitter trolls and the roots of the panama papers.
Talk 5 - Particle Systems for Fun and Profit
This talk by Matt Hayes (@mysterycommand) was about particle systems, optimizing them, and what other uses they can have. It was a lot about how to reason about the render loop, how to save memory by pregenerating a list of assets and reusing them, and a really cool bit on infinite scrollers.
He posted his sliders on twitter
Having been to the scala version of this talk by Martin Snyder, this was pretty cool seeing the same concepts being applied. I felt like a lot of the developers may have gotten lost pretty quickly, but Martin Synder did a great job of stepping through the functional programming concepts and why they might be used instead of some of the alternatives.
The workshop is available on Martin Snyders github.
Talk 2 - Please Touch: Creating Applications for Museums
This talk by Kathryn Stracquatanio and Sarah Polansky went over creating interactive web applications with touch that are meant to run 24/7, 365. It was dealing with chrome in kiosk mode, memory management with large interactive assets, distributing updates in a live system, and dealing with multi-display interactions. It was pretty cool and an interesting application of web technologies into a new area I had never explored.
Lunch was, once again, awesome.
This talk by Hao Luo was hilarious. He is a Microsoft Evangelist who touted how proud he was to never use a microsoft technology. His talk on Aync/Await walked through cleaning an imperative script by using Promises. Then by cleaning up Prosmises using Generators. Then cleaning up generators to have an identical implementation as Aync/Await. It was a clever view at how async/await was working under the covers and the patterns that lead to its implementation.
Talk 5 - Un-dux Your Front-end
Talk 6 - Building the Foundations of the Node.js Community
This talk by Tierney Cyren was mostly him going over his history with the Node community and how be is now part of the Node.js Community Committee. There was a lot about how node is awesome and how active the community is, but not a lot of substance besides stats and history.
Talk 7 - Serverless Architecture and LibertyJS
The first part of this talk by Pam Selle, was an explanation of what is serverless and how it is changing the landscape of the web. The second part was a recognition piece on what it takes to setup LibertyJS, acknowledging all of the people who volunteer to make it happen, and hyping up the future of the conference.
There were two afterparties, one was an open wine and beer bar at JJ Bootleggers with a Taco Bar. The second was at a dance club provided by the DJ to DJ’s the entire event.
Overall it was a great conference. There was a good representation of the big tech companies of Philadelphia, and I was glad I was able to convince my employer, Jornaya to sponsor the event. There was a wide range of topics, some of which I will be doing follow up writing on, paired with good people and good food. I will definitely be attending LibertyJS next year.
