These days he works on maintaining large libraries like VCR. He talks about what VCR is, why it’s useful, and some of its limitations. The real topic of today’s show is Kubernetes. Kubernetes is an open-source container orchestration system for automating application deployment, scaling, and management. Kurtis describes what it is and some of the features it has.The panel discuss about some of the limitations of Kubernetes, and where it really shines in the development lifecycle. Kurtis advises Kubernete users to leave their databases as an outside source and not put them in Kubernetes, as well as other things to avoid. They talk about methods for encrypting information within Kubernetes.The panel discusses how Kubernetes compares to other services and some of the unique features.The panel discusses what it’s like to learn Kubernetes. Kurtis advises listeners who are learning Kubernetes to consult with other people who are experienced with. Kubernetes has some different terms for functions that can be confusing to newcomers. It can take between 3 and 6 complete weekends to become comfortable using Kubernetes. Kurtis shares how to transfer a Rails app into Kubernetes. To get started with Kubernetes on the cheap, find a computer with a decent amount of ram,install Ubuntu and MicroK8s for a perfect tinkering playground.LinksSinatraVCRAPIpod/containerLoki by GrafanaStateless servicesNamespacesChefPuppet DockerfilesHeroku PG BouncerHephy WorkflowGitlab Auto DevOpsHelmUbuntuMicroK8sAzureCloud66Config mapsIngressPrometheusCD/CIHashi Follow DevChat on Facebook and Twitter PicksNate Hopkins:HerokuHow To Be Like Walt book  Real Genius film Andrew Mason:Peacock VSCode extensionDrifting Ruby ep. 181- Intro to KubernetesDavid Kimura:Microk8s.io and ‘Microk8s.reset’ command Kubernetes Slack channelKurtis Rainbolt-Greene:Satisfactory gameKubernetes on Rails video seriesSpecial Guest: Kurtis Rainbolt-Greene.

Now he has his own show, Ruby Testing Podcast and runs the site codewithjason.com where he teaches Rails testing. Today, Jason discusses turning fat models into skinny POROs (Plain Old Ruby Objects). He once read an article that said you don’t have to put all your code into active record models, that you can create plain ruby objects. These can go into active models if you want, but you’re not limited to active record models, you can make your own classes. This realazition greatly impacted the way he structures his code.The panelists talk about the individual ways the structure their code. Jason discusses other structuring methods he has tried and gives some examples of using skinny POROs in the apps he works on. They discuss the pros and cons of using skinny POROs instead of active models, pros being it cleans up the model and makes testing easier, and the cons being it adds to a bit of overhead to the application, as somebody unfamiliar with the application might recreate parts if you don’t have an index.The panel discusses how to decide when you want to create a new PORO. They talk about each of their methods and discuss the the usefulness of token generators. They conclude that in order for skinny POROs to be effective in code, they must be well factored and organized, and that unfortunately some complexity in code is unavoidable.LinksPOROs- Plain Old Ruby ObjectsModelActive record modelsNamespaceService objectsValue objectsCSSForm objectTokensInitializerSingleton objectPicksDave Kimura:ReekKubernetesCharles Max Wood:Cloud66PodwrenchPodcasting boothNew podcasts coming to DevChat-- if you want to revive a podcast that has stopped airing, contact Charles Max WoodProgramming Podcasters Slack chatJason Swett:Practical Object Oriented Design in RubyRuby Testing PodcastCodewithjason.comSpecial Guest: Jason Swett.

He has been freelancing for the past 10 years, working especially in open source. He received the Ruby Hero award in 2010. His latest work is with his own creation, Zeitwerk, a more efficient code loader for Ruby. Zeitwerk will be included in Rails 6, but is an independent gym for now. Xavier talks about his inspiration for Zeitwerk and his desire to improve constant outloading in Rails.The panelists delve into the features of Zeitwerk. Any conventional library can use Zeitwerk, so you don’t have to write requires. Zeitwerk is designed to make your development work easier because you don’t have to worry about including in or requiring files in your code snippets, it will intelligently auto load those in. Zeitwerk functions slightly different from classic mode Ruby, because in Zeitwerk, you don’t go constant name to file, instead you are given a file name first,  and then add it to a constant. Xavier delves into the limitations of classic mode and the const-missing callback, and how Zeitwerk improves upon this problem by using only absolute paths and module outloading instead of const-missing. The result is that, in general, things load faster.They discuss indexing of absolute paths within Zeitwerk, how one of the principles of Zeitwerk is to be as lazy as possible, the memory footprint, and the configuration needed to opt into Zeitwerk.  Overall, Zeitwerk is going to work like Ruby. There are no special rules, it has the same semantics as Ruby, fewer gotcha’s if any at all, control over inflection, ways to introspect, and a way to log the activity of Zeitwerk.LinksZeitwerkKubernetesAPIHTMLConst-missing callbackNestingAncestorsModule outloadingBootsnapBootstrapAbsolute pathPicksDavid Kimura:Nerf GunsEric Barry:Octotree Chrome extensionXavier Noria:Time TrapSpecial Guest: Xavier Noria.

The panelists discuss the naming of Ruby as the Server-Side Programming Language of the Year in 2018, beating out PHP and Java. Karthik talks about incorporating Ruby into Oracle. His team uses Ruby in both development and operations, and having a common language has increased their efficiency. The panelists discuss the shift from constant servers to more volatile servers that can make provisions on the fly. Karthik explains the benefits of using Oracle Cloud Native over other services. Oracle places a lot of emphasis on helping startups by giving them more computing power than other companies. Karthik talks about the merits of using Kubernetes in testing and production, and encourages those interested in using Kubernetes to jump in and start learning about it. For startups that want to use Kubernetes but lack a specialist, Karthik suggests letting a cloud service (like Oracle) manage the servers. Finally, Karthik tells listeners how to get started using Oracle Cloud, namely:Go to cloud.oracle.comClick the green “Try For Free” button to create your accountGo into the Oracle Cloud Console and start exploringPeople who sign up get $300 in free credits  Links: KubernetesOracle Cloud NativeCapistranoChefPuppetHirokuOracle FunctionsCNCF (Cloud Native Computing Foundation) Picks Andrew:Archipelago Eric:Desk Mini FridgeAsynci (in beta) David:Presonus Studio channel amplifier Karthik:Visual Studio CodeCloudnative.oracle.comKarthik’s team blogSpecial Guest: Karthik Gaekwad.
