- Hello There
- (01:15) Kevin introduces Rob.
- (02:05) Kevin asks Rob about his Xaml platform work with Caliburn.Micro. Rob says he’s transferred that work to Nigel Sampson, and it’s alive and well.
- Comparing Aurelia with Angular
- (05:25) Rob also wanted to target transpiled languages so it worked well with ES6, ES5, TypeScript and Coffeescript. By comparison, Angular was pretty focused on Dart and AtScript.
- (06:12) Jon references Rob’s post comparing Angular and Aurelia code and asks about conventions. Rob describes how conventions work, how you can create your own conventions, and how you can override conventions by providing metadata (but only for overrides, not all the time).
- (08:56) Rob describes how binding and the templating syntax work. Aurelia minimizes additional markup for binding, whereas he sees Angular syntax focused on theoretical tooling experiences that could be built, but nobody’s committed to. Also, while Angular’s syntax is technically valid, it doesn’t work with cases like SVG. There’s a secondary binding syntax to work around that, but having two syntax doesn’t seem like a clean solution.
- (12:31) Kevin asks for examples of conventions in Aurelia. Rob explains how custom elements work with EcmaScript 6 modules and exports. No metadata is required, as compared to Angular which requires specifying metadata in all cases even if you’re not using them. Rob also explains custom attributes (again using a simple exported class). Naming conventions set up the mappings so no metadata is required. Value converters are yet another example – the naming convention assumes that any class ending in ValueConverter is automatically registered and configured.
- (16:43) Rob says that in Angular you need to declare all directives you’re using in your view models. That really bugs Rob because the implementation details in the view shouldn’t be reflected in the viewmodel. That was required for lazy loading, but he sees it as a design problem and a maintenance problem. Rob says that Aurelia uses an import in the view and doesn’t touch the viewmodel, using the EcmaScript 6 loader. Rob says that this design makes some conventions impossible.
- The Aurelia Pitch
- (21:08) Scott K says he likes the class-based design in Aurelia and asks Rob for a quick pitch for Aurelia to sell it to a team. Rob talks about the clean, standards based design that allows decomposing complex screens without requiring extra configuration. It’s easy to build, extend and maintain. Rob also talks about the binding syntax, and the ability to plug in other binding strategies by dropping in an adapter. The binding strategy system has been tested out with Breeze.js and Knockout, allowing you to use your existing models without requiring unnecessary dirty checks.
- (26:42) Scott K asks how object.observe works with tranpilers. Rob says there’s a polyfill that generates getter / setter pairs if object.observe isn’t available. Rob explains how this works with the micro task queue, and how it allows for queued tasks to handle queued work efficiently. Rob talks about the task-queue in Aurelia, and how it can be used outside of Aurelia as well. Rather than directly observing DOM elements, the task queue allows for batching changes for efficiency.
- (35:15) Kevin asks if Aurelia handles a persistence layer. Rob says that rather than building that, they’ve worked to make it easy to plug popular persistence libraries in. He also discusses the validation system they’re working on.
- (38:22) Jon asks if Rob’s looked at PouchDb and references Herding Code 181, in which Max Thayer explained PouchDb.
- Why not write my own framework?
- SVG use
- (44:40) Jon asks if Rob thinks people will use SVG. Rob says it’s more about building a production-quality framework, then gives some possible usecases like graphs, mapping and custom elements. Rob says that people do all kinds of things you might not expect when they use a framework, and building a real framework requires it. Kevin says at his last job they’d started converting image sprites to SVG, and it was a pretty good use-case.
- (49:05) Kevin asks about Rob’s thoughts on React. He says it’s a good renderer, but it’s not a framework. He and Scott K agree that React is a library, not a framework. Rob says he wrote a blog post in which a custom Aurelia element uses React as a custom renderer. The Babel transpiler allows mixing JSX with ES6 code, and this allows continuing to use Aurelia binding. In general, Rob says really smart, but if you need a framework you’ll end up cobbling a bunch of things together to use it. Instead, he’d recommend using a framework like Aurelia and just pulling in React when it’s required.
- (53:22) Kevin asks if Rob’s considered adding a virtual DOM to Aurelia. Rob says it’s not clear that there would be an advantage in most cases.
- Isomorphic rendering
- Questions from Twitter
- (57:25) Question from Twitter (@cecilphillip): "What’s the rendering perf like compared to ReactJS?" Rob says that React is going to be a lot faster for initial render time, whereas Aurelia is probably going to be faster for updates. It’s hard to give an accurate comparison; Rob says they’re mostly focused on being fast enough rather than the fastest. He says Aurelia’s not slow now, but they’re focusing on some upcoming performance enhancements that he’s expecting big results from.
- (1:02:09) Question from Twitter (@csharpfritz): "can you talk about what lead to the choice of architecture with JSPM?" Rob explains how JSPM integrates package management with module loading. Aurelia isn’t directly dependent on JSPM, so you can use other package managers and loaders if you want. Jon says the one thing he wants JSPM to integrate rate limiting so he doesn’t hit the GitHub rate limit; Rob says this is being addressed in a future release since most cases don’t require the hitting the rate limited API.
- Scott K’s Packaging Rant(tm)
- (1:08:11) Scott K has a "short rant" about NPM, JSPM and all package managers in general: they all use existing config files (like gitconfig) and should be tested behind corporate firewalls and proxies. And then there’s the nested package thing, which doesn’t work well on Windows due to path length limits. Jon says he uses the flatten-packages package. There’s a short group rant about the file path length limit on Windows.
- Final questions and wrapup
- (1:13:40) Jon asks if there are any patterns or thoughts on server-side development for Aurelia. Rob says there are starter kits on the way, and people are using Aurelia with lots of back ends (.NET, node, MEAN, etc.). He talks about samples on the way, including a Todo app (even though he thinks Todo apps aren’t useful for application frameworks).
- (1:17:15) Kevin asks where Aurelia’s at in a release cycle. Rob says it’s currently in preview / alpha phase but targeting a beta around June or later. Don’t go to production with it now, but get ready for the release after that.
The guys talk to Ahmet Alp Balkan about Docker, containers, building an ASP.NET 5 image for Docker, and working on the Azure Linux team at Microsoft.
Download / Listen: Herding Code 202: Ahmet Alp Balkan on Docker
- Working on the Azure Linux team at Microsoft
- (00:17) Jon introduces Ahmet and asks what it’s like being on the Azure Linux team at Microsoft. Ahmet explains what his team does. Ahmet’s mostly a Unix stack developer, he doesn’t use Windows on a daily basis.
- (02:20) Jon asks Ahmet if it’s strange working on open source and Linux and Microsoft, and if there are a lot of legal requirements.
- Intro to Docker
- (03:48) Jon asks Ahmet to describe how Docker works, and how it compares to traditional virtual machines.
- (05:54) Jon asks about how the Docker works with the Linux filesystem approach. Ahmet explains namespaces in Linux and describes how namespaces provide separation between instances. One benefit is that each instance is really lightweight, so you can have hundreds of instances on one physical machine.
- (09:47) K. Scott asks about a specific example deploying a Ruby on Rails application. Ahmet describes two options for creating a creating an image – either doing it manually or using a dockerfile. K Scott and Ahmet discuss inheritance chains for containers.
- (13:35) Kevin asks about how inheritance works when you’ve got an application that relies on services in different parent containers – is there communication between them? Ahmet describes how the application files are based on diffs from each container level. Rather than modifying a running container, you should instead define and deploy a new instance.
- (17:07) K. Scott asks how different configuration between machines is handled.
- Docker on Windows
- (18:13) K. Scott wonders how containers will work on Windows due to the registry. Ahmet talks about how it’s more difficult on Windows, since on Unix everything is a file; Jon remembers the previous interview with Kenji at Spoon about how they’re virtualizing the registry with their container system.
- (20:40) Jon points out that since Docker images run on top of a host, they’re not portable between different hosts on different operating systems.
- ASP.NET 5 Docker image and User Mode sandboxing questions
- (21:21) Jon asks Ahmet about his work on creating an ASP.NET 5 Docker image.
- (23:10) Scott K. asks about the difference between Docker images and running in user mode. Ahmet explains that Docker does run in user mode, so things are kept separate due to user mode sandboxing.
- (25:14) Kevin asks if the host operating system has visibility to the running containers.
- (26:12) K. Scott asks if there were any technical hurdles in creating the ASP.NET 5 Docker image. Ahmet talks about how the image was built and the general process of developing with Docker instances.
- Getting started with Docker on Windows
- (30:15) Jon asks about different ways of getting started with Docker – Boot2Docker (running on top of VirtualBox), spinning up a Docker instance on Azure, etc.
- (31:54) Jon asks about Ahmet’s work on getting the Docker client on Windows. Ahmet talks about some of the differences in Windows operating system API’s, including Go language differences.
- (36:00) Scott K. says he’s excited about Docker because it sounds a lot simpler than some of the deployment issues he deals with.
- Docker in production and container orchestration
- (37:17) Kevin says he’s heard that running Docker in production is more difficult than running it in development. Ahmet talks about some of the orchestration efforts that are underway, and talks about container linking and the datacenter operating system approach.
- (43:14) Jon asks about Mesos. Ahmet describes what Mesosphere is doing and how it relates to orchestration.
- (44:50) Jon asks if Azure orchestration will be similar. Ahmet says they want to play really well with the other schedulers out there.
It’s Time To Get Over That Stored Procedure Aversion You Have – Rob Conery
Rob’s advice would be great if people wrote stored procedures the same way they wrote normal statically typed code using C# or Java. But they don’t, they tend to cram every possible path for the business logic can take into a single stored procedure, making it hard to understand, hard to maintain, and fragile.
Everyone has heard or had to deal with that kind of stored procedure. Written years ago, the authors have moved on to another job, everyone shudders at the thought of having to modify it. Then one day, it stops working, maybe it’s due to a change in the underlying table, maybe a new business requirement came up that requires a new kind of data to be passed to the procedure.
ORM’s were originally created so that:
a) We could stop writing 4 different stored procedures for every object in our programs.
b) So that we could normalize our data in the database and then create object models in our application code that represented business concerns rather than the most efficient way to store data.
Jon meets Kenji and Trevor at a small airfield in San Diego to talk about Spoon, an application containierization and streaming platform for Windows. They discuss different virtual machine approaches, Spoon’s features, the container movement, and flying airplanes.
Download / Listen: Herding Code 201: Kenji Obata on Spoon, application virtualization, containers, and flying little airplanes
- Application virtualization and Xenocode’s origins
- (00:17) Jon says hi to Kenji and describes his first interaction with Kenji – a blog post he wrote in 2007 titled "We should be virtualizing Applications, not Machines" and Kenji’s response saying that’s exactly what they were doing at Xenocode. Kenji describes application virtualization and lists some of the vendors working in that space.
- (1:51) Jon asks about the spectrum of virtualization – starting with virtualizing the entire machine and file system and dialing back. Kenji describes how Xenocode started with a solution that would allow for deploying .NET applications without requiring a separate .NET framework installation. This had minimal virtualization – just enough to virtualize the .NET framework.
- (06:07) Kenji describes the work to move from virtualizing the .NET framework to supporting application virtualization for any arbitrary Windows application, culminating with virtualizing Office.
- Moving from application virtualization to application streaming
- (08:24) After solving virtualization for any Windows application, Xenocode moved on to tackling application delivery – solving long downloads, installation, and application conflicts. They also wanted to do this all over the web, which was the genesis of Spoon. This had a lot of appeal to business users rather than just coders, so they rebranded from Xenocode to Spoon.
- (11:15) Jon asks about application streaming with the example of Office Click-to-Run. Kenji discusses Click Once and how that relates to MSI installers. While some application streaming solutions solve the problem of "click button, run application" they are still installing on the computer so you hit problems with conflicts between applications.
- (13:20) Spoon applications are portable because they’re not installed on the local machine. Kenji and Jon discuss how installing an using an application start changing the state of the machine in many places outside of the application directory – registry, user profile, etc.
- (14:30) Kenji describes how many of their enterprise customers have complex legacy applications which blend several technologies and don’t always follow best practices.
- Docker and containers
- (15:35) Kenji talks about how they’ve grown from looking at the smaller, targeted problem of virtualizing and deploying a single application to a holistic view of containers as a fundamental part of the development and deployment process.
- (16:30) Kenji says that the excitement around Docker has got the community thinking more about application virtualization. Jon asks Kenji to explain how Docker-style virtualization is different from traditional virtual machine virtualization. Kenji explains how Docker was originally built on Linux lxc in which the kernel can segregate itself into several namespaces. Jon asks how it relates to file system virtualization, and Kenji says that since in Linux there’s an "everything is a file" philosophy, it’s easier to segregate things this way.
- (18:10) Kenji says that there’s really no virtualization engine in Docker, it’s more of a set of scripting languages around Linux features. Kenji says that perhaps Docker’s biggest contribution is the term "container" since it’s more consumer-friendly and makes it more obvious that containerized applications are portable.
- (19:55) Jon says that his experience with Spoon is that it felt like git for virtual machines. Kenji says that Docker actually uses git for storage. He explains how the storage needs of application virtualization lend themselves to git-like storage.
- (21:44) Kenji says that containers on Windows are more difficult because there isn’t an lxc feature in the kernel. Fortunately, Spoon already has a vm engine that can provide that.
- Advantages to running in user mode
- (22:12) Kenji mentions that Spoon is running in user mode rather than kernel mode, and explains why it’s important to segregate and run child systems in user mode without any need for kernel access. Users don’t need any special privileges to install Spoon applications, and even if there are security issue in the virtualized applications, they’re always just running as an unprivileged user the host operating system.
- Getting started with Spoon
- (24:10) Jon talks about the user experience on Spoon.net – quick install with no permission prompts, and a console window pops up.
- (25:24) Kenji points out that because Spoon started with virtualizing desktop applications, the Spoon container approach works well with any Windows application, including GUI applications.
- Virtual networking features
- (26:12) Jon asks how he can add add to a Spoon VM once he’s created it. Kenji points out one approach by spinning up another VM and connecting them using Spoon’s virtualized network feature. He talks about how you can use the virtual network features to point your application with multiple VM’s all using virtualized networking and the virtual DNS service.
- (29:20) Jon talks about how virtual networking on other systems like Hyper-V can be problematic because it’s messing with the host operating system’s network adapters and networking configuration.
- Spinning up multi-VM environments
- (30:28) Jon says that all of these features sound really useful for testing, because he can spin up an entire environment, test it all, and delete it, all from a script. Kenji says they’ve put a lot of focus into those scenarios, and since Spoon VM’s are so lightweight that you can spin up 20 or 30 VM’s on a dev machine. He talks about a customer that has about 20 servers in their test environment and spins them all up for tests on a single host.
- Selenium support and legacy Windows features
- (32:42) Kenji says they have first class Selenium test grid support, allowing web developers to run automated web tests against a wide variety of operating systems and browsers. Jon asks how this works IE versions are tied to versions of Windows. Kenji talks about the Windows version support they’ve built into Spoon, allowing a Spoon host on Windows 8 to run every IE version back to IE6.
- (34:37) Kenji talks about Windows version support and stacks and conditional layer support in Spoon to allow wiring in complex emulation behavior so you can deliver one image that will run on a variety of Windows hosts.
- Working with images and state
- (35:44) Jon asks about how the "spoon run dotnet,jdk,node,nginx" support works, and Kenji says you can use that to compose an arbitrary number of base images.
- (36:36) Kenji says that they heard a lot of customers were bringing in git support to build a project that’s hosted in git, but they didn’t really want it in the image. They added another "using" primitive to allow you to use support from an image without adding it to the base VM.
- (37:53) Jon asks how to add features to the Spoon VM after it’s been created, in the case that he really does want them there. Kenji says that I can just save the container’s state as an image, then build another container on top of that image. Images are static, containers are not.
- (39:01) Kenji talks about the state abstraction, allowing you to continue from any saved state id. These move between different computers, which is helpful for testing and parallelization.
- The Spoon.net hub and what you can do for free
- (41:00) Kenji mentions the Spoon.net hub, which is free to use for public use – similar to GitHub. Jon asks about what’s available for free use, and Kenji says Spoon.net use is unlimited (within reason).
- (42:01) Kenji explains how their previous version required their Spoon Studio tool to configure applications, similar to App-V sequencing. Things are simplified now with Spoon – you just grab a clean image, install software on it using the standard installers, and commit the image and you’re done.
- (44:04) Kenji highlights the advantage of having the clean image readily available, so you can easily get a clean Windows install to try or test software – just by typing "spoon run clean".
- Trying things with "spoon try"
- (45:13) Jon says he likes to use VM’s to get a clean machine state, and also to be try installing some software without risk. Kenji talks about the "spoon try" command, and explains how try automatically wipes all your state when you’re done (whereas spoon run maintains state).
- Deployment options
- (47:38) Jon asks how IT managers roll out Spoon solutions to their users. Kenji says they provide a set of tools to integrate with existing deployment models, including support for desktop icon registration, scripting, and the web interface to allow launching from intranets.
- Size and performance impact
- (49:00) Jon asks about the size of a Spoon VM. Kenji says it’s essentially just the size of the installed software and the state, so it’s pretty minimal. Storage is delta-based, so it’s small. The Spoon database includes de-duplication to allow for frequently saving state without bloat.
- (51:01) Jon asks about the performance impact due to virtualizing everything. Kenji says that since the VM’s are so lightweight, it’s very minimal. He gives examples of high-performance users, including AutoCAD and video game developers.
- Azure RemoteApp support
- (52:29) Jon asks Kenji about something he saw on the site mentioning that Azure support was coming soon. Kenji gives us an exclusive scoop on the upcoming RemoteApp support. This allows you to create a single base VHD on Azure with just Spoon installed on it, then use Spoon’s support to host any application via RemoteApp. He says it’s great to be able to use RemoteApp support when he’s on his Mac to run any Windows applications he needs.
- (56:53) Jon recommends for listeners to go to Spoon.net and try it in a few seconds for free.
- Flying little airplanes
- (57:21) Jon notes that they’re recording the podcast at an airfield and asks Kenji and Trevor about how they got into flying. Jon notes how high-tech the plane controls are and asks how it compares to Microsoft Flight Simulator. Kenji talks about the excitement and terror of his first takeoff.
- (1:01:29) Kenji says that an easy way to give flying a try is to contact a flight school at your local airfield and set up an introductory flight for about $100 – $150 to give it a try.
The guys talk about the Node / iojs fork, Angular 2, K Scott’s new Microsoft Band and other wearables, Kickstarter successes and failures, container technologies like Docker, and some recent articles about women heroes of coding.
Download / Listen: Herding Code 200: io.js, Angular angst, K Scott’s new Band, Kickstarters, Containers and Old School Elite Women Coders
- The Node / io.js fork
- (00:41) Jon asks Kevin what’s going on with the io.js fork. Kevin says the fork is due to the Node team’s slow release cycle. Jon asks what technical things people are looking for, and whether io.js code is supposed to be compatible with Node code. Scott K lists some of the features planned for Node 0.12. There’s some general discussion about what this means long-term and whether this will be a temporary or permanent fork.
- Angular angst
- (06:21) Jon asks K Scott what is going on in the Angular world. K Scott summarizes why people were bent out of shape over the Angular 2 announcements.
- (07:30) Jon asks what this all means from Angular developers – what’s actually changed? K Scott discusses how the team isn’t worrying about migration from Angular 1.x. He mentions AtScript and the guys discuss how it relates to TypeScript. Kevin asks if Google is the new Microsoft, in that everything has to be their way. K Scott says it’s feeling like MEF composition.
- (12:09) Scott K says he thinks the radical changes are to support components and dart. K Scott says he also sees that runtime introspection looks like an important goal.
- (13:30) Scott K talks about the migration plans and the announcements that 1.x won’t be getting any new features. Kevin says this puts Angular developers in a tough spot, because 2.0 isn’t going to be out for a while and 1.3 is the final release in that branch. Scott K says he’s stopped paying much attention to it for now while waiting for things to shake out. There’s a discussion of Durandal now that Rob’s left the Angular project.
- Wearables and the Microsoft Band
- (17:30) Jon asks K Scott about his new Microsoft Band. K Scott says he likes the notifications and sleep notifications. Jon asks if the sleep notifications are actionable or just telling you things you already know; K Scott says he’s notices that poor sleep for three nights in a row affect his communication skills.
- (20:25) Jon says he hasn’t been able to pull the trigger on Pebble, even on super sale, but the Band looks really interesting. The voice input for Cortana looks neat, too.
- Windows Phone interlude
- (21:55) K Scott says he helped a friend pick out a Windows Phone and was impressed by the inexpensive models from Blu. Jon talks about how all the new Windows Phone models are nice inexpensive phones rather than flagship models. Jon mentions the app coverage and says that all the big apps seem to be available, the only ones he misses is an app from his bank to deposit checks.
- (24:30) Kevin says it seems like Windows Phone is swimming upstream on apps, mentioning recent articles from Tom Warren and Ed Bott.
- Wrap up on wearables
- (25:55) Jon asks Kevin what he’s thinking on the Apple Watch. He says he’s intrigued and wants to play with one to see.
- (26:55) Scott K says there’s not much you can really do on a tiny screen, so consuming content on a watch is silly. Jon says that he sees room for things like two-way communication and remotely controlling the desktop. Scott K says his Pebble is kind of like a second screen for his phone. He says there isn’t enough horsepower on a watch for voice recognition, but the other guys all jump in to say that the watches use Bluetooth to work with the voice recognition on their phones and it all works pretty well.
- (32:15) Jon says he’s backed ten projects, but only three of them really turned out well: gourmet marshmallows, a web-based font creation program called Prototypo, and a file manager called OneCommander. Scott’s had good success because he does some due diligence on the shipping background for the creators.
- (35:15) Scott says he avoids tech projects on Kickstarter because he knows geeks, and he knows the overestimate what they can do: they all think they’re physicists, nutritionists, lawyers… they think they know everything, and they don’t anticipate the cost and effort to go from prototype to shipping product. Jon says he’s seen two software projects that were flawlessly executed – BitCommander (since renamed to OneCommander) and Prototypo. In both cases the creators were very communicative throughout the project.
- (39:55) Kevin’s never Kickstarted anything because he doesn’t want more things. Jon says he usually backs things because he wants to support someone doing something cool, not because he wants a project. He says he frequently sees popular new technology Kickstarters that are recreating something he can find already shipping on Amazon for a lot less. Kevin says he finds the whole Kickstarter thing is completely fascinating, and he’s amazed that it seems to work. Scott K talks about how many game manufacturers use it to figure out how many to produce rather than to start figuring out how to produce a project. Jon mentions a Sony epaper watch that was Kickstarted just to gage interest and says that the goal of Kickstarter is to actually graduate to shipping product and lists a few; Kevin talks about the Veronica Mars movie.
- (47:20) Jon talks about Docker and Rocket and asks if the guys are using them yet. Kevin says that poor OSX support (requiring VirtualBox Boot2Docker) has cooled the interest in Docker in his shop.
- (48:55) Jon says he thinks the container approach seems like a nice middle ground between running a native process and a full virtual machine. He says that he’d like to talk to the Spoon team soon to hear about their Windows native container system.
- (51:15) Scott K talks about the Mesos system – a distributed systems kernel. Jon searches around and finds it’s an Apache project. The idea is that you can move your Linux applications over to it, then scale across commodity hardware. Jon worries about the latency but figures eventually you overcome latency with processing power if it’s distributed right.
- Women In Computers, Old
- (55:05) Scott mentions an article about Margaret Hamilton, the software engineer who wrote the code for the Apollo Eleven and came up with the term hardware engineer. Scott says that the Apollo source code is up on Google Code.
- (56:45 )Jon talks about an article he saw about the programmers who wrote code for the Colossus in World War Two, and they were all women. Kevin says he saw an article about how until the early ’80’s the distribution was even until there was an advertising campaign that was geared to boys, and things changes after that.
- (58:20) Scott talks about an article he read about The Sotry of Mel, who was working so close to the metal that he optimized for where the memory would be located on the physical memory drum.
Jon talks to Rob Reynolds about how Chocolatey has grown over the past few years, how OneGet fits in, and the Chocolatey Kickstarter.
Download / Listen: Herding Code 199: Rob Reynolds on the Chocolatey Kickstarter, Chocolatey growth and OneGet
- The state of the Chocolatey
- (00:19) Rob explains what Chocolatey is and compares it to package managers on other platforms. Jon talks about how he uses Chocolatey to install all his programs every time he installs Windows.
- (02:10) Rob talks about how Chocolatey has grown in the past 3 1/2 years.
- Package Moderation
- (02:24) Rob explains how package moderation works – whereas previously all packages were immediately published and reviewed later, now they’re reviewed by moderators before they’re listed. One common fix is just getting the naming right.
- (05:24) Rob talks about how they’re curating the community feed. They’re currently in a grace period until December 1; some packages are that aren’t broadly applicable are being told to move to MyGet. Jon and Rob talk about other hosting options (anything that host NuGet) and benefits of using the NuGet infrastructure underneath Chocolatey.
- (07:25) Rob talks about the checksumming features they’ve added.
- Chocolatey Pro
- (09:03) Rob explains how Chocolatey has grown, partly due to the OneGet announcement – they’re up to 7 million downloads now, half of them in the past six months. He talks about how the costs have grown over that time.
- (11:40) Rob explains what the Kickstarter supports. The free / open source version will always be free. They’re also adding in professional-only feeds and a content delivery network to support the professional feeds. Jon asks and Rob explains the professional feeds work.
- (14:50) Rob explains how the pro version includes additional virus checking via Virus Total.
- (15:31) Jon says it sounds like most of the money is to provide for infrastructure. Rob agrees, but says some will help buy him some time to work on it. He talks about the example of Octopus Deploy – development has really accelerated since it became a full-time endeavor.
- (17:05) Jon asks what OneGet is. Rob explains that it’s a package manager aggregator and works with the Chocolatey feed right out of the box. Rob and Jon talk about the advantages of having Chocolatey support installed in Windows.
- (20:20) Jon asks about the impact to the Chocolatey team. Rob clarifies that they’re a provider, so they build the hooks, and OneGet will read directly from their feed.
- Windows Store
- (21:02) Jon asks if Rob’s worried that the Windows Store will someday add Win32 app support and make Chocolatey irrelevant. Rob says he doesn’t expect it, but even if they did there are some big differences between a store and a package manager. Jon and Rob discuss package managers, meta-packages, dependency management and package uninstallation.
- Kickstarter Benefits
- (24:36) Jon asks Rob to explain the different Kickstarter award levels. Rob discusses Chocolatey Pro pricing and some of the higher level awards like a custom workshop. He points out that the pricing is perpetual, so by backing the Kickstarter you’re locking in the price.
- (29:00) Jon says that even if you don’t care about the rewards, if you’ve been using Chocolatey you should consider supporting the project. Rob describes why they came up with their goal amount, including the Kickstarter and Amazon transaction fees.
- (21:29) Rob and Jon mention ways you can get involved. Of course you can back the Kickstarter, but he’s also really appreciate any press or exposure.
