At Techorama 2014 (Belgium), Jon corners Mark Rendle for a few minutes to talk about his new startup, Zudio, "the Azure Cloud storage toolkit," his keynote on the History of Programming, and other minutia.
Download / Listen: Herding Code 193: Mark Rendle on Zudio, developing with Angular and Typescript, The History of Programming, and Simple.Data
- History of Programming
- (00:54) Jon asks Mark what the talk was about, and some of his personal favorite periods.
- (01:53) Jon remarks that some of the joke terrible languages weren’t much worse than the unintentionally terrible languages. Mark mentions Intercal, brainf*** and Malbolge as joke programming languages and IBM Cobol as the most unintentionally hilarious programming language.
- Zudio: The Azure Cloud Storage Toolkit
- (02:55) Mark talks about how Zudio got started and where it’s at. Zudio is a web based tool for managing Azure storage. It’s great for a lot of users, especially PHP / Node / Java developers and in the enterprise. It’s built with AngularJS and Typescript.
- (04:37) Jon said he assumed it was just a simple table grid, but there are seem to be a lot more advanced features. Mark talks about the new enterprise model, which lets you control your user list through Azure Active Directory (which can be synchronized to on premises Active Directory), and you can assign different access rights to users and groups. There’s also auditing and logging to track usage.
- (05:29) Jon asks if he’s specifically focused on storage. Mark talks about upcoming support for SQL databases, including Azure SQL, SQL VM’s, ClearDB running MySQL, Oracle VM’s, Postgres via VM, etc. that will show run queries and show results in a grid, list tables and views, etc. Jon compares it to phpMyAdmin, but Mark says it’s for any database and deployed in the same datacenters, without you needing to spin up a web server. His stretch goal is to handle data migrations between different database systems.
- Angular and Typescript
- (07:19) Jon says that Mark’s been a fan of Angular and Typescript for a while and asks why he likes the combination so much. Mark says it feels like the data binding framework Microsoft’s been trying to build since VB3.
- (10:24) Mark says that unlike most frameworks he’s worked with, he’s gotten to the end of a project using Angular and doesn’t want to throw it out, so that’s saying something.
- Simple.Web and Simple.Data
- (11:33) Jon asks Mark what’s going on with Simple.Web (a simple .NET web framework with attribute routing and dependency injection). Mark says that everything that had driven him to create Simple.Web has been added into ASP.NET vNext, so Simple.Web is pretty much done.
- (14:50) Simple.Data is Mark’s simple data access layer that leverages dynamic types and can work without any code changes against a lot of different databases.
- (15:52) Jon asks why someone would use Simple.Data instead of Entity Framework. Mark explains how Simple.Data works really well in lightweight web frameworks; it’s so simple you can code to it without IntelliSense.
- (16:47) Mark is focused on updates to Simple.Data for use in Zudio, and will we working on more metadata, performance, and async support. He’s looking at moving to async only and is interested in listener input on that.
- Wrap up
- (18:13) Mark likes all the new stuff and thinks it’s a good time to be a programmer.

The guys talk to Jackson Harper about CodeReview, his iPad application for reviewing GitHub pull requests. As Jackson describes the episode on Twitter: "…hear me talk about:
@johnsheehan, @codereviewapp, and my one weird trick for writing better code."
Download / Listen: Herding Code 192: Jackson Harper on the CodeReview iOS app
- Hello. What is CodeReview?
- (00:18) Kevin introduces Jackson and asks about CodeReview. Jackson talks about how he missed
- (01:25) Kevin asks about some of the specific features in CodeReview.
- (02:05) Jon asks what the CodeReview app adds to the mobile web experience on GitHub. One of the big features is that CodeReview allows for completely working completely disconnected.
- Nerdy Implementation Details
- (04:10) Kevin asks if Jackson’s working against the GitHub API’s. Jackson says he debated working using Git directly, but so far he’s been using the GitHub API. Internally the code is abstracted so in theory it could work against other source code hosts like CodePlex. There’s a brief discussion of Google Glass
- (05:45) Jon asks about Jackson’s development stack. Jackson says he’s working directly in Objective-C and some C as well for the Markdown parser. There’s some discussion of the joy of writing parsers in C. Jackson talks about how some old formats like diff are so much simpler to parse than even newer formats like XML and JSON.
- (08:15) Jon asks why Jackson didn’t use Mono for this application. Jackson says he’s writing Objective-C for his day job, so it’s good for him to write as much Objective-C as possible. Kevin said it seemed like working with Mono would require learning Objective-C to read the documentation. Jackson agrees, but says that learning the iOS APIs using Mono made the transition a lot easier for him.
- (10:46) Jon asks about the BetterFetch feature. Jackson talks about he’d originally modeled the application more like a Twitter stream, so he’d been using the stream API. Over time, it became obvious that an e-mail client was a better application model, so he’s moved off the steam API.
- Business Model and Pricing
- (12:47) Jon asks about the business model and pricing. Jackson said he and JB originally thought that they’d use a freemium model, but they figured out that it really was more applicable for business users who can’t as easily do in-app purchasing. He’s switched to a flat rate to allow for group purchases and generally work better for business scenarios. Kevin says $20 is pretty steep for an app, but Jon says it says it seems completely reasonable for the right application with one of his favorite Android applications which cost $20. Jackson says it’s a perpetual license, iPad apps often sell for a little more, and since it offers a lot of value to businesses he thinks it’s worth it. They’d originally looked at $4.99, but that’s hard to make any money off. Jon says he thinks that the price sensitivity between $4.99 and $19.99 is probably a lot less than between free and 99 cents. Jackson says he wants to sell and support a quality application that’s sustainable.
- Services? Nope, just more repos.
- (18:03) Kevin asks if it’s all run off GitHub or if there are some hosted background services. Jackson says it’s all running off GitHub. He supports storing additional profile data in an optional GitHub repository. Since he knows you’ll have a GitHub application, he can include support for retina quality profile images (and potentially other information) stored in GitHub.
- Design issues
- (20:54) Kevin asks if he’s been working with a designer or doing it himself. Jackson talks about how he’s worked with a few designers and it’s really helped.
- (22:50) Kevin asks if the application’s design reflects GitHub’s design. Jackson says it’s similar, but explains some important differences between the application and the website.
- (24:27) Jon asks about the full screen experience. Jackson explains how it both frees up screen real estate and allows you to focus.
- Code Reviews and Separating the Creative and Editorial Process
- (25:24) Twitter question from Elijah Manor: "Do you use the CodeReview app to review code for the app itself?" Jackson says yes and explains how a bit inspiration for the application was Stephen King’s writing workflow: bang out a bunch of pages in the morning, edit in the evening. Separating the creation and refining steps allow for a lot more productivity. Jon’s very interested and asks Jackson for tips on how to do that. Jackson talks about setting small goals and working in a coffeeshop without bringing his power adapter, so he’s constrained on time and internet use. K. Scott says that the iPad form factor probably helps for this, and Jackson agrees – he sees it as really good for focus.
- (30:41) Jon asks if there are other features he could add by gathering intelligence about my codebase and workflow. Jackson mentions some ideas like hotspots and detecting patch impact. He’s been watching GitHub’s career page hoping to see that they’ll be hiring data scientists to start providing this kind of information. Jon agrees that it’d be great for GitHub to start investing in data science. Jackson says that you could get a pretty good start on patch impact just by manually flagging a few files as important. Kevin says this would have been useful in the case of OpenSSL.
- Code Reviews and Git Workflows
- (34:29) Jon asks about workflow support for larger teams and team hierarchy. Jackson talks about some of the different Git workflow methodologies. He says he might eventually add support for code review tools like Gerrit, although he feels that some of these tools give code review a bad name because they force you to look for minutia as opposed to the big picture.
- When Does it Ship
- (37:56) Jon asks how close he is to shipping. Jackson talks about the beta and some of the challenges of running a beta. [Note: the application is now up on the app store]
- Metrics, Tracking and API Profiling
- (37:35) Jon asks if he’s tracking metrics or tracking. Jackson says he’s gathering crash reports and doing some very basic analytics using localytics because he doesn’t want users to be concerned. Jon says he likes applications give checkboxes to allow for extended tracking. Jackson talks about how he’s using Runscope and would like to allow users to optionally turn Runscope on. Jackson and Jon rave about Runscope; Jackson talks about how a few hours of API profiling helped him significantly improve the application performance. Jon talks about how we don’t think about server interactions, and there’s all kinds of crazy, scary things going on behind the scenes. Jackson tells a horror story about how the Mono site used to return the logo image when you tried to download, and they didn’t find it out until they looked at the server logs. Jon talks about a case where someone requesting the Herding Code RSS feed several times a second.
- What’s Next?
- (48:39) Jon asks what’s next for the app. Jackson talks about the difficulty in cutting off the features and shipping a version.
- (49:29) Kevin asks if he’s got big vision for more than code review. Jackson says he just wants to ship it and will probably start looking at other features eventually. Kevin talks about a polititian who’s put all of his information on GitHub. Jackson says he’s worked with a lawyer in setting up the company and wished they he could work in Markdown. Jon talks about how it would be nice if Markdown had review and change tracking that were similar to Word’s. Jon says that the recent hosted Sharepoint releases are getting close. Kevin, Jackson and Jon talk about how foreign the idea of versioning and change tracking is to most professions.
- Random questions
- (55:35) "Who is the best canadian you know" (Wayne Gretzky)
- (55:55) "What type of dog is your favorite" Labrador
- (55:57) "When will you stop lying about your tweets" There’s a short discussion about deleting tweets and Jackson’s feature request for Tweet focus testing. Jackson talks about a time when Twitter asked users to stop deleting tweets for performance reaons
- (59:20) The app is now live on the app store! You can find out about it at CodeReview.io.
- (1:00:32) Jon asks for some promo codes, Jackson gives away ten free promo codes (below)!
Promo Codes for show listeners (please just take one, leave a comment when they’re all gone):
The guys (joined by guest host Rob Conery) talk to Derick Bailey about his new podcast audio hosting venture, SignalLeaf.
Download / Listen: Herding Code 191: Derick Bailey on SignalLeaf and Getting Started Podcasting
- What is SignalLeaf?
- (00:18) Kevin introduces the show and warns listeners that Rob Conery is present.
- (01:00) Kevin asks Derick what SignalLeaf is. Derick explains that SignalLeaf is a podcast audio hosting service. He explains how his service compares to big players like Libsyn.
- (02:05) There’s a discussion of Libsyn. Jon confesses that Herding Code still runs off WordPress on an "unlimited hosting" account.
- Bandwidth costs
- (02:52) Jon asks Derick if the main cost is bandwidth. Derick explains that SignalLeaf runs on Heroku, but all the storage goes directly to Amazon S3 storage. He agrees that bandwidth is the main cost, and is planning to just make sure the overall subscribers balance out some of the more expensive bandwidth costs.
- (04:52) Jon asks Derick what else he provides outside of audio hosting. Derick says he provides audio hosting, an RSS feed and stats, but he limits it at that. He also provides a blog with a lot of good information. The goal isn’t a big all-in-one service, just keeping it simple for people who want to get started.
- (06:31) Rob gives the example of the rapid takeoff of This Developer’s Life and asks how Derick’s planning to handle pricing for unpredictable bandwidth. Derick says the model’s focused on unlimited uploads, but limited in how many releases a podcaster makes in a month. He’s relying on the law of average to pay for the popular podcasts.
- (09:18) Rob talks about the huge streaming bills he was getting from Amazon for TekPub, which he almost eliminated by switching to Vimeo. He asks Derick if he’s looked into services like that. Derick says the backend is abstracted so he can move to other services if needed.
- What does SignalLeaf run on? (Part 1)
- (11:10) Jon asks about what SignalLeaf runs on. Derick mentions MongoDb (running on MongoLab), Keen.io for analytics and CloudAMQP.com for RabbitMQ.
- What services does SignalLeaf provide?
- (13:25) Kevin asks more about the services SignalLeaf offers. Derick mentions storage, bandwidth, storage and analytics. Something he offers beyond what many other similar services provide is – if you use his RSS feed and embedable audio player – he can tell you where your listeners are coming from.
- (14:50) Derick mentions his blog post showing that about 50% of listeners don’t listen via RSS. Jon said he’s seen the same thing with the Herding Code site.
- Stats and advertising services
- (17:25) Jon says advertisers are always asking for stats, and the kind of stats that advertisers want are hard to find. Derick mentions a service (blubrry) that inserts audio ads, but doesn’t think that sounds like a good idea. He mentions a business podcast running on a free service which had some off-color ads included as an example.
- Getting started in podcasting: What equipment and software do you need?
- (20:40) Rob asks how a developer should get started with creating a podcast. Derick says just hit record and get started. Don’t buy equipment, just record something and upload it and get started. He talks about professional podcasters who put artificial barriers up by focusing on radio quality recording; he disagrees.
- (23:56) Jon mentions Derick’s recent post on getting started. He agrees with Derick and says don’t start by buying equipment, get started and buy equipment as you need it.
- (26:11) Jon says he doesn’t use his high end condenser microphone because it picks up lots of noise and sounds strange compared to guests and other hosts. Rob asks Derick what people getting started should buy to start with. Derick recommends starting with a $26 Logitech headset, then looking at a $50 Audio Technica ATR 2100, a $90 Blue Yeti, $220 Rode podcaster mic etc.
- (30:15) Rob asks about recording software. Derick mentions Garageband, Skype Call Recorder and Audacity. Jon uses a free Skype call recorder from scribie.com, Audacity and Reaper.fm. Jon and Derick both love the noise removal feature in Audacity.
- (33:26) Jon says another thing to figure out at the beginning is how much you want to edit. Jon tries to focus on removing ums and repeated words and things, but leave it sounding natural. Both Jon and Derick say that Rob’s the easiest guest to edit.
- (35:40) Jon asks K. Scott what he uses for recording. He uses Audacity and Camtasia. Jon tells a story about how how he spliced in audio from a previous call when one of the hosts couldn’t make a show. It didn’t make sense, but no one seemed to notice.
- (36:50) K. Scott asks what kind of formats don’t work on a podcast. Derick says that visual features and visual cues obviously don’t translate.
- What does SignalLeaf run on? (Part 2)
- (38:21) Rob asks everyone to guess about the technology Derick’s running on. Turns out it’s all Node.js. Derick talks about how he got started with Node.js. Jon asks about what other libraries he’s using. Derick mentions Express, S3 restful API’s for upload and host, raygun.io for exceptions, keen.io for analytics, stripe.com for billing, MongoDb for data, Mandrill App for SMTP. Derick talks about how little it takes to build up a service now – he’s able to stitch a lot of services together to build what he needs. (45:30) K. Scott asks what text editor he uses. Derick’s a big VIM fan, having started with a Visual Studio VIM extension a while ago.
- (50:07) K. Scott asks whether Derick uses Grunt or Gulp. Derick says he’s thought about looking at Gulp, but Grunt works for him, although he doesn’t like .
- Discussion about managing small, application specific Node modules
- (50:55) Derick says he doesn’t like the way NPM wants you to have a separate git repository for each module – he wants to have all of his modules in one repo. He works around that by using different repositories for development and deployment. Kevin says that his company uses softlinks to work around that, but Derick’s not happy with that. Rob thinks you can do file references, but Derick and Kevin disagrees. Jon asks if submodules would work. Rob and Derick discuss cases where it does and doesn’t make sense to use different repos for different small modules which are specific to a project. Rob talks about using grunt to run an npm install command, or npm init or start scripts (set in package.json), or npm init.
- (1:01:55) Kevin asks Derick if there’s anything else he wants to mention. Derick starts to mention WatchMeCode.com but the calls keep dropping and the show spontaneously combusts.
Somewhere in the bowels of the code base for sites like Facebook and Twitter and flickr and Azure and Heroku, there is code, I bet, to specifically deal with IP addresses.
And that code will lose it’s SHIT completely if we switch to IPv6.
In our final interview from NDC London, Jon and K. Scott talk to Rob Ashton his cage match with Jeremy Miller on NodeJS vs. C#, some functional languages he’s been learning, and cooking just enough curry.
Download / Listen: Herding Code 190: Rob Ashton on NodeJS vs C#, Clojure and Cooking Constraints
- The NDC Cage Match: Testing! NodeJS vs. C#
- (00:18) K Scott asks Rob about the cage match he just had with Jeremy Miller comparing testing in NodeJS and C#. Rob’s got a lot of good things to say about what Jeremy showed, but is pretty sure he won.
- (02:40) K Scott asks Rob to explain why he doesn’t like monkey patching. Rob mentions how QuickCheck helps, then talks about how code structure obviates the need for monkey patching.
- (05:16) Jon asks how he bootstraps his application to inject dependencies and explains how he avoids deep dependency chains.
- (06:40) K Scott asks what led him to Clojure.
- (07:39) Jon asks Rob what he likes about Clojure. Rob says a better question is what he likes about functional programming languagues, then explains.
- (09:25) K Scott asks about some of the learning project Rob’s been working with to learn Clojure. Rob talks about some of the games he started with, then the RavenDb reimplementation he’s been building with Clojure called Craven.
- What do you do in your free time?
- (12:56) K Scott asks Rob what he does in his free time. Rob starts by talking about Clojure, then talks about some of the complicated cooking things he’s been working on. He talks about some of the similarities between cooking and coding, and some of the constraint he deals with in ambitions cooking projects.
- The future
- (14:58) K Scott asks Rob about some of his plans for early 2014. Erlang away!
If we throw an argument about how to and how not to design a framework into the mix this
thread will probably gain sentience and destroy us all.
