Michael Jolley discusses how every project a developer works on is unique, using various frameworks and tooling and how requiring developers to identify & install these dependencies clutters their machine, increases on-boarding time for new team members, and increases potential security threats. Learn how using Visual Studio Code Remote Development to perform all development work inside “throw-away” Docker containers prevents the need to install third-party frameworks & tooling; use standardised development Docker images to ensure a consistent development experience and speed up on-boarding; and attach to and debug code running in existing containers.
How does Natural Language Understanding work? What insights can we glean from the data it provides? Join Ben Greenberg to take a dive into understanding how this technology works, and apply it in a Ruby app that connects Natural Language Understanding analysis, the daily headlines and social media all in one.

A no-slides, hands-on, live debugging session using only the browser Developer Tools on the website Alex picked from the JSUnconf audience. A deep dive into spotting performance bottlenecks into any website and how to fix them.
Flexbox, Grid and Box Alignment are the cornerstones of modern CSS layouts. They introduce behaviours that might seem confusing if you don’t completely understand how the browser inteprets the CSS values you assign, e.g. sizing with Flexbox, or the various options for sizing tracks in Grid. This talk will explain a variety of modern CSS layout techniques through live demonstrations via DevTools, and provide real-world use cases of how such techniques allow designs to better adapt across a broad range of viewports.
When using WebSockets to communicate between your server and the client every new browser context–tab, window, iframe, and so on–is likely to create another WebSocket connection. All these open connections can quickly take a toll on your server resources, or if you’re using a PaaS which charges for each connection, it could quickly add up to a big bill. In this talk, we’ll look at how you can use SharedWorkers to create a single persistent WebSocket which can be used by every browser context to communicate with your Django Channels WebSocket server

This webinar looks at the OpenTok SIP Interconnect capability, which can be connected to any SIP system or gateway. We will look at this generally, and then in addition we will showing the coding to connect this to the Nexmo SIP APIs in order to get PSTN connectivity. Nexmo provides a global Communications Platform as a Service (CPaaS) providing a full range of communications capabilities. The webinar will cover: What is SIP (high level)? OpenTok SIP Interconnect Using NEXMO SIP APIs for PSTN connectivity
Episode 5 in this webinar series looks at how to Manage Live Video recordings through the OpenTok APIs and platform. This episode covers: Recording/archive API Composed stream vs Individual streams recording Use of Amazon S3 and Microsoft Azure storage Security, privacy and compliance

This is a recording of our first webinar in this series on Video Chat Embeds, which are the easiest way to quickly add basic OpenTok functionality to a website by cutting and pasting an embeddable HTML snippet. Manik’s agenda includes: - Setting up Video Chat Embeds through the Dashboard - Adding Embeds to a website, including with WIX and other website builders - Functionality of Embeds - Suggested use-cases for Embeds - Comparison with using the full OpenTok API (which will be covered in later episodes).
Open API Specification is a machine and human readable way to describe APIs. From these specs we can generate documentation, create libraries, and ensure that our users know exactly what to expect from our APIs. This talk shows you around OAS from the beginning, showing how to create the specs and recommending some tools to help the process. Once you have the spec, things get interesting and this talk will showcase some of the things that you can offer once your API is described in this way. This session is recommended for writers looking to become more API-savvy and API engineers wanting to make their APIs more useful to their users.
Starting with nothing, we'll build a package and publish it on PyPI using current best practices! Learn how to structure, document and test your project on different platforms. Discover the difference between `setup.py` and `Pipfile`. Finally, use CookieCutter to avoid doing it twice (or even once)!
A Phileas Fogg inspired tour of 8 frameworks "Had he programmed? It was likely, for no one seemed to know web frameworks more familiarly; there was no framework so obscure that he did not appear to have an intimate acquaintance with it. He must have developed in everything, at least in the spirit."
In this coding session, Aaron Bassett creates a traditional PSTN proxy in Kotlin, which he uses to connect two telephone endpoints while keeping both sides of the call anonymous.
In this coding session, Nexmo Developer Advocate Aaron Bassett shows how you can handle webhooks from the Nexmo Voice API, where each webhook represents an inbound call to enable the integration with a CRM, database or analytics platform like MixPanel.
In this coding session, Nexmo Developer Advocate Aaron Bassett shows how to make a fast and scalable voice broadcast system for sending critical alerts or notifications using asynchronous Python and the Nexmo Voice API.
In this coding session, Nexmo Developer Advocate Aaron Bassett demonstrates how to connect an inbound call to an agent as well as to IBM Watson Tone Analyzer via the WebSockets feature of the Nexmo Voice API. He also shows how you can take the analysis from Watson and display it to the agent.
So you've released a library! Now you need to maintain it. You want to add features, restructure the code, fix bugs, and maybe improve the library's usability. Your users just want their code to carry on working. That's okay! This talk covers techniques in both code and project management to allow you to keep your code moving forwards without breaking your users' code.
Model mommy lettuce factory boy expects gherkin behave. Travis mock splinter nose phantom hypothesis! Most developers recognise the importance of testing in building maintainable software, but the sheer volume of tools and approaches can be bewildering and sometimes make it sound like you’re talking a different language.
Discover how you can use Artifical Intelligence to perform sentiment analysis of an audio stream, in real-time!,In this workshop, we’re going to learn how to create a virtual rapporteur. A digital assistant who can join any conference call; record it, and then by using IBM Watson provide participants with a real-time transcript and insights into the overall tone of the call. All pushed to their browser via WebSockets.
Building a DevRel programme is hard. What are the goals of the programme, how do they align with the company goals, what activities should the new Developer Relations team undertake, how do those activities help other departments within the company and how should the success of the team be measured?
