Demystifying Git - Version Control From First Principles
Join on Hopin
Dwayne McDaniel
Dwayne McDaniel
GitKraken, Developer Evangelist

Git is the defacto standard version control system in use today. Every developer learns the basics of add, commit, branch, merge, pull, and push, and that is about all they learn about Git.

However, if you ask how Git actually works under the covers, most people will tell you they don't really know. Worse yet, when most developers see Git output messages like "detached HEAD state" or "CONFLICT (content): Merge conflict", they get a stress-induced panic.

This session will peel back the shroud of mystery that envelops Git, showing that there is nothing overly complex or terrifying about the inner workings of the world's most popular version control system. This talk is for everyone, from the complete Git novice to folks who have been pushing code for years but maybe have never stopped to look at how Git does its thing.

OPEN TALK: Unit Security Testing for JavaScript and Beyond
Join on Hopin

Bright Security, Developer Relations

Application security is a problem in the development world, with expensive, complex, and sometimes only piecemeal solutions. But fix the problems you must, as there will come a time when someone will try to hack your app, probably (hopefully) your security team or a penetration tester. Once they find those problems, you have to then go back and fix the security bugs, 6 months to a year later, and that can be a real pain.

In this talk, you’ll learn how to turn this issue on its head, with unit security testing. Unit security testing is a tool we developed here at Bright to solve the problem of needing to rely on an external tool or team instead of being self-reliant in your approach to writing secure code. By integrating our DAST engine with unit tests, you, the developer, are empowered with the know-how of how to find vulnerabilities as early as possible in the SDLC, without the security team getting involved and having to fix problems far later on in the process.

In this session, you will learn
How to integrate unit security tests in your JavaScript applications (other language support coming soon!) using Bright, Jest & Nest.js
How to write different types of tests and which issues are important to test for
How to fix some vulnerabilities that our tests find in an example web application

An ounce of prevention is worth a pound of cure, so you will also learn how to defend against some common attacks from the get-go as you are writing code.

Turing, Community Evangelist

Technical aptitude will take an engineer far in their career but ultimately it's the ability to navigate workplace environments through the refinement of soft skills that will determine the heights that your career can scale.

In this session, Vanky Kataria (Evangelist - Global Communities) will share how focusing on soft skills can play an instrumental role in your career development and explain how engineers benefit from thinking about their workplaces beyond their roles and responsibilities as technical professionals.

Wearable Live Captions (Making Mask Wearing More Accessible for Those Who Are Hard of Hearing)

Ably, Developer Advocate

During the pandemic we've all been feeling pretty isolated, and we've all been doing our best and wearing masks. But what if everyone wearing masks cuts off your ability to converse?

My dear mum relies on lip reading and clear sounds to understand what people are saying. But I, of course want her to stay safe. So the thought occurred. Can I make a live captioning display fit into a mask so that she can read what I'm saying as I'm speaking?

This talk will cover how to build a wearable LED display, how to use Microsoft Azure Cognitive Services to convert speech to text, using Ably's MQTT broker to send messages to a microprocessor and some good old JavaScript and C++.

Live captioning of speech to text has so many useful applications and Cognitive Services makes it fast and easy to build captioning into your applications. Together with Ably Realtime, it is possible to make wearable devices which can display what you’re saying, in real time. Wearable Live Captions!

Patricio Vargas
OneSignal, Sr.Developer Advocate

As web performance and user experience across both mobile and desktop devices continue to increase in importance, so do progressive web apps (PWAs). PWAs are becoming more popular because they have lots of enhancements that help your application perform better and they make apps accessible even to users with limited internet connection. In this talk, you are going to learn the advantages of using PWAs and how to turn your web application into a PWA.

Application-Specific Blockchain Layer 2S: Strengths, Opportunities and the Future
Join on Hopin
Alexander Baigent
Alexander Baigent
Fluidity Money, Chief Technology Officer and Co-Founder

Layer 2s including rollups are being adopted for scalability and throughput. In this talk we explore existing examples of application-specific rollups and how they compare to more general ones implementing the EVM. We explore using type systems to generate layer 2s and show how an advanced type system with code generation can be used to generate networking topologies. We speculate on no-code solutions that could be built in the future.
