Hacktoberfest Tuesdays: Europe

27 October 2020

Hacktoberfest — brought to you by DigitalOcean in partnership with Dev & Intel — is a month-long celebration of open source software. Maintainers are invited to guide would-be contributors towards issues that will help move the project forward, and contributors get the opportunity to give back to both projects they like and others they've just discovered. No contribution is too small — bug fixes and documentation updates are valid ways of participating. Vonage is thrilled to be a Hacktoberfest 2020 partner. We’re no strangers to Open Source, with our libraries, code snippets and demos all on GitHub. We’re looking forward to supporting participants, sharing our knowledge and chatting about how important and awesome open source contributions can be!

MLH Fellowship: Build a Call-In Phone Line With Pre-Recorded Messages with Kevin Lewis

Learn how to accept incoming calls and respond with both a pre-recorded MP3 file and synthesised speech. In this project, we learn about Serverless using Netlify Functions, and utilizing Airtable as a database. The final project is a phone line which users can call to hear today’s MP3 ‘thought of the day’, with a fallback message read if there isn’t a recording for today.

Create Delightful SDKs from OpenAPI

OpenAPI is a standard for creating a very detailed and machine-readable description of your API. Once you have that, the machines can use it to create all sorts of goodness. This session will focus on how generated SDKs can fit into a Developer Experience strategy, enabling users to generate code for their own use, or going a step further and curating captivating libraries with accurate, maintainable, generated code at its core. We'll look at some examples, and some occasions when the fairy tale may not be all we hoped it would be. This session is recommended for anyone with an interest in Developer Experience for APIs.

MLH Fellowship: Build a Serverless Video Conferencing Application with Kevin Lewis

In this workshop, we'll build a serverless video application with Node.js, MongoDB, Netlify Functions and the Vonage Video API. It is suitable for those with little (but some) JavaScript knowledge.

Introduction to OpenAPI

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.

Flask: How "Micro" of a Microframework?

In this session, we will talk about flask. How much of a "microframework" it really is, and how extensible it can be. It is as simple (or complex) as you decide! Let's see where all the superpowers of this awesome "microframework" come from and how "micro" it really is.

Introduction to Computer Vision in .NET

Low-Code for Developers

Low-code solutions are on the rise and visual builder tools are opening up creation to a wide range of users. In this session, we’re going to look at low-code tools like Node-RED and Zapier, what they have to offer, and whether they have a place in a developer’s toolkit.

Think inside the box. Developing inside a container to avoid conflicts, improve security and speed up on-boarding.

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.

Using DevTools To Understand Modern CSS Layouts

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.

Reduce, Reuse, Recycle - Persisting WebSocket connections with SharedWorkers

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
