    Broadcasting with SignalR and .NET Core Boradcasting with SignalR and .NET Core

    SignalR is a library for .NET developers for adding real-time web functionality to applications. It is often used for real-time chat applications but is also great for live dashboards and games!

    SignalR takes advantage of several transports, automatically selecting the best available transport given the client and server's capabilities. SignalR uses WebSockets under the hood when available, and gracefully falls back to other techniques and technologies when it isn't.

    I've recently been working with Twitch chatbots and wanted to use SignalR to update browser scenes based on commands sent in via my viewers.

    This meant that I would need to call a SignalR broadcast from a different project.

    This blog will share how to do that.

    If you would like to see my completed project, it's available on my GitHub here.

    What you'll need:

    • A basic knowledge of ASP.NET Core
    • .NET Core 3.1 installed
    • An IDE such as Visual …

    5 Questions to Ask Yourself before Working with a Dataset header img dataset

    Recently I was looking for some datasets to analyze and make predictions based on data for a blog post project. I got stuck when I kept running into datasets that were fun but not good: oftentimes, AI projects struggle due in part to data-related issues.

    What makes a dataset good or bad? What are some things you should consider when looking at a dataset? How should you interpret a dataset, from beginning to end? Read on to find out!

    5 questions to ask yourself before working with a dataset

    1. How was the data compiled? 

    Was it aggregated from multiple sources? Did you compile it? If it came from different sources, you may have to format the data so different variables within a given attribute are consistent, such as dates, times, addresses, states or cities (maybe they’re abbreviated?), numbers like currency, etc., and some of the data may not be …

    Twilio's Omni-Channel Approach: A Self-Service Win/Win, Finally Realized Selfserv win-win

    The idea of “DIY” (do-it-yourself) is nothing new. Yes, it has grown in popularity recently due to tools such as Youtube, Instagram, and the like, but the concept of DIY has been around since the 1950’s. People take pride in being able to carry out professional grade tasks without direct aid from experts or professionals.

    In the Contact Center world, we want customers to have tools to do things themselves – without a live agent. The promise of self service has proven elusive. For decades we have struggled to provide rich experiences that create high satisfaction with self service applications. I submit that a combination of new capabilities, shifting customer preference for omni communications and an increased willingness to do-it-yourself has finally allowed us to realize the self service win-win where both businesses and customers benefit.

    Attempts at self-service in customer interactions

    The idea of self-service is sound; companies …

    Using RxJS Observables With JavaScript Async and Await rxjs-observables-async-await.png

    There are a number of resources for handling asynchronous tasks in JavaScript, each with its own strengths and suitability to specific tasks. Sometimes a single tool is all that’s necessary to accomplish a task, but there are programming challenges which can be handled more effectively by combining the capabilities of tools.

    RxJS Observables enable you to operate on sequences of data, like the results of a REST API call, as if they were events, acting on new and updated data from the Observable object when the change occurs. They’re great tools to use when the timing of data events is unpredictable, like when you’re dealing with slow or occasionally unreliable web services.

    JavaScript Promises are useful when you need a placeholder for the results of a task that might fail and need to respond differently depending on the task’s success or failure. Promise objects can be used with the JavaScript …

    Measure the App Size Impact of Android Libraries apkscale Header

    Users – especially those with pay-per-byte mobile plans – will avoid downloading Android applications if they are too large. As a result, managing your Android application size helps ensure that users are not deterred from trying out your application. Google provides great strategies for reducing your application size, but many applications depend on third-party libraries which may not consider their app size impact.

    Here at Twilio we understand this challenge, which is why we publish the app size impact of our Voice and Video Android SDKs with every release. Our CI pipeline contains a size measurement step, so we ensure that we do not introduce any unexpected size regressions during the development process.

    Today, we are happy to announce that we have open sourced the utility we use to measure the size of our Android SDKs: apkscale.

    Apkscale is a Gradle plugin that helps measure the app …

    Building a real-world Twilio application in ASP.NET Core Building a real-world Twilio application in ASP.NET Core and C#

    As developers, we are well-used to taking a mix of code examples and trying to figure out how to actually implement these disjointed bits into a real world application.

    In an effort to make this process easier, I created a detailed, real-world five-part video workshop!

    I've used .NET Core to build the application in the workshop. .NET Core is an awesome framework and completely cross-platform, so whether you are on macOS, Windows or Linux, you can follow along with the code.

    The workshop utilises Twilio products such as Twilio Studio, Twilio API for WhatsApp and Twilio SendGrid.

    The workshop focusses (that's the British spelling for my American grammar checking friends!) on building out an ASP.NET Core 3.1 MVC application for The Cloud City Cake Co.. The Cloud City Cake Co. loves using tech to make the lives of its customers easier through technology.
