http://traffic.libsyn.com/sedaily/ErrorDiagnosis.mp3Podcast: Play in new window | Download When a user experiences an error in an application, the engineers who are building that application need to find out why that error occurred. The root cause of that error may be on the user’s device, or within a piece of server-side logic, or hidden behind a black box API. To fix a complex error, we need a stack trace of contextual information
http://traffic.libsyn.com/sedaily/GatsbyJS.mp3Podcast: Play in new window | Download GatsbyJS is a framework for building web applications for JavaScript. Gatsby’s original goal was to allow users to create super fast static web sites that could be hosted and served efficiently at a low cost.

http://traffic.libsyn.com/sedaily/QATesting.mp3Podcast: Play in new window | Download Quality assurance testing is a form of testing that closely mirrors user behavior. Sometimes it is manual, sometimes it is automated. Automated QA tests are scripts that validate correct data representation as the application mechanically runs through high-level workflows–like a login page. Manual QA testers act out use cases of an application to see if there are any bugs that were missed during
http://traffic.libsyn.com/sedaily/OpenComputeProject.mp3Podcast: Play in new window | Download Facebook was rapidly outgrowing its infrastructure in 2009. Classic data center design was not up to the task of the rapid influx of new users and data, photos and streaming video hitting Facebook’s servers. A small team of engineers spent the next two years designing a data center from the ground up to be cheaper, more energy efficient, and more ergonomic for the
http://traffic.libsyn.com/sedaily/TypeScriptatSlack.mp3Podcast: Play in new window | Download Slack is an application for team communication. Users chat across mobile devices, web browsers, and a desktop application, which means Slack has three places to deploy on rather than two. And the desktop apps on Windows, Mac, and Linux are not identical, so Slack has even more places to deploy. With so many different runtime environments, Slack needs to make technology choices that
http://traffic.libsyn.com/sedaily/Lottie.mp3Podcast: Play in new window | Download Animations make an application more fun and engaging. For most apps, animation is an afterthought. Developers are concerned with getting the functionality right, and designers have enough work to do simply getting icons, text formatting, and page layout correct. There is also the issue of cross-device compatibility. iOS, Android, and web have different ways of doing animation, with no unifying standard–except gifs, and
http://traffic.libsyn.com/sedaily/StateofJavascript.mp3Podcast: Play in new window | Download JavaScript is moving so fast. It’s not easy to keep up with all of the frameworks, build tools, and packages. No other language spans frontend to backend, mobile to web to server.

http://traffic.libsyn.com/sedaily/ServerlessCD.mp3Podcast: Play in new window | Download Serverless computing reduces the cost of using the cloud. Serverless also makes it easy to scale applications. The downside: building serverless apps requires some mindset shift. Serverless functions are deployed to transient units of computation that are spun up on demand. This is in contrast to the typical model of application delivery–the deployment of an application to a server or a container that
http://traffic.libsyn.com/sedaily/ServerlessBurningMonk.mp3Podcast: Play in new window | Download After raising $18 million, social networking startup Yubl made a series of costly mistakes. Yubl hired an army of expensive contractors to build out its iOS and Android apps. Drama at the executive level hurt morale for the full-time employees. Most problematic, the company was bleeding cash due to a massive over-investment in cloud services. This was the environment in which Yan Cui
http://traffic.libsyn.com/sedaily/VijayPandeQuantum.mp3Podcast: Play in new window | Download Quantum computing is based on the system of quantum mechanics. In quantum computing, we perform operations over qubits instead of bits. A qubit is a vector, which can take on many more values than 0 or 1. The technology used to implement quantum computers is advancing such that it has its own Moore’s Law, but it can also leverage the classical advancements of
http://traffic.libsyn.com/sedaily/HerokuCI.mp3Podcast: Play in new window | Download Continuous delivery is a model for deploying small, frequent changes to an application. In a continuous delivery workflow, code changes that are pushed to a repository set off a build process that spins up a new version of the application. Testing is performed against that new build before advancing it to production, merging it with the existing codebase. Many continuous delivery products are
