JavaScript Debugging with Alex Liu, Todd Gardner, and Yunong XiaoDescription:JavaScript has a pretty interesting debugging story.The developer tools of your browser of choice and thevarious tools and IDEs for debugging Node or mobiledevelopment make for a really interesting topic.Show sponsors:Egghead.io - Bite-sized web development video training Frontend Masters - Expert front-end training {Track:js} - JavaScript Error Monitoring Wallaby.js - Realtime code coverage Codecov.io - Code coverage done right Fluent - Web development trainingLinks, Picks, and Tips:Alex LiuTips: Always think about Errors and error handling as part of the design and spec from day one and Understand the abstractions you use, especially when it comes to Errors Picks: VError, bunyan, restify-errors, and Overheard - VS Code debugger is great  Todd GardnerLinks: TrackJS for debugging non-chrome platforms, Charles Web Debugging Proxy, and Fiddler Proxy Picks: JavaScript Error Monitoring, JavaScript Forensics Talk, Amazing Conference in Oslo, Afterparty conference, Author: Ken Follett. Pillars of the Earth and a World Without End, and Conference Satire  Yunong XiaoLinks: mdb v8, Node post mortem debugger, Debugging Node.js in Prod, Flamegraphs, Flamegraphs with Node, Restify, Observable Rest Framework, and Debugging Node Tips: Use the Scientific Method, Error Types and JSON Parse, Error Handling in Node.js, JSON Logging Lib, and Observable Async lib Picks: Bojack Horseman, ReactiveSocket, and Wish You Were Here  Brian LonsdorfLinks: Elm’s debugger and Free Monad graph Tips: Algebraic data structures like Either, Task, and Maybe ensure we handle all errors. The errors are pushed to the caller where it’s easy to see., In node, you can overwrite Obj.prototype.inspect to display a custom string when console.log-ing., and Learn to use debugger; in the browser. Picks: Bodil Stokke Generators and Profunctor Lenses  Kyle SimpsonTips: Chrome CPU Throttling, OSS your code early. Don’t wait until “it’s good enough for others”, because then you’ve waited too long. OSS is about collaboration and improvement, not promotion of already-finished code., and Start with libraries and frameworks as you rapidly develop/evolve/explore a project. But as it matures, try to build time in for refactoring to reduce/remove those pieces. You don’t need them permanently. The best code is the code that’s exactly what’s needed, no more, no less. Picks: About the new ‘createImageBitmap(..)’ API and also ‘requestIdleCallback(..)’, Chris &amp; Getify Make A Game (part 1) tutorial on simple  game making with me and @chriscoyier, and Cloud Sweeper my first  casual web game, OSS code released  Kent C. DoddsLinks: Async checkbox in Chrome DevTools and Managing Memore Garbage Collection in NodeJS - Egghead.io lesson Tips: Teach to learn. Force yourself to teach.

Node.js at Netflix with Yunong Xiao

restify is a node.js module built to enable correct REST web services. Netflix uses restify to gain performance and visibility. Yunong Xiao, senior engineer at Netflix, talks about the incident which incited Netflix’s service migration to restify. The discussion starts with an explanation of flame graphs and evolves into a conversation about restify, and the importance of choosing the correct RESTful API.
