Episode 41 - "Various" and some technical issues

por Mark Mandel and Kai Koenig

For episode 41 we wanted to be so professional. Kai took his podcast microphone to his co-working space (which is on a really fast fibre connection) for a better recording quality to then have their internet connection break apart halfwalf though our podcast. We actually recorded on the 24th of January - just to make it clear that this is our January podcast and that we're TOTALLY on track for at least one podcast a month in 2017. Since the 24th, Mark was trying to get the editing done and then it was sitting with me for another 2 days until I managed to publish it.

But - we managed to talk about things. Starting off with Kai's house ethernet and wifi rewiring we went on to Mark's "living-in-the-bay-area" bubble and then talked a bit about Ubiquti Wifi gear. As usual we then quite quickly diverge into various aspects of gaming and gaming development tech (Daydream gets a worthwhile mention, too). An interesting discussing arose from that: What'd be the impact on flight training using VR? In particular if you're looking a cost/benefit and potential savings of not having to do as many training flights in a real plane or a very, very, very expensive simulator.

Another tangent was the use of open-source software in the various communities we're hanging out with. Looking at game developer, web dev and enterprise software communities, there's obviously quite a bit difference in how open-source software is used and how the idea of open-source software is fostered.

Episode 40 - Happy Holidays

por Mark Mandel and Kai Koenig

Welcome to 2016's show of 2DDU. Yeah, we know. I guess it was one of "those" years.

Anyway - we managed to squeeze in a recording, live from Mark's flash podcasting studio at Google and Kai's home office in Wellington's leafy suburb of Karori. Just in case you don't like the audio quality on Kai's side - that's gonna improve for episode 41, whenever that might be...:-/

In this episode however, we play a bit of catchup with our respective lifes and talk about what tickeled our fancies in 2016. For Kai that's essentially Android development and in particular Kotlin. Not unexpectedly Mark's focus in 2016 was on various cloud-y things.

We then talk a little bit about events we've been to, Pokemon Go and other games, how cool the Nintendo Switch will be. Obviously episode 40 also contains the mandatory air travel-in-the-US rant from Kai and a short discussion of Frequent Flyer program usage.

We're committed to be doing much better in 2017. Challenge Accepted, world!

Episode 39 - SeaweedFS, Docker, Jetbrains and various philosophical language ramblings

por Mark Mandel and Kai Koenig

After just another multi-month hiatus, we're proud to finally publish Episode 39 (now featuring and actual intro music!!!!). This time, we're talking about a whole bunch of different things. Starting off with a brief discussion on what each of us is currently playing (Kai got back into the Nintendo handheld world while Mark is playing Farcry 4 on his PC), we're getting into SeaweedFS, which looks like as if it's a really cool "NoFS" distributed file system/file storage. Kai's been toying around with it a bit and its technology is based on Facebook's Haystack paper. The paper itself is really worthwhile having a read.  Mark's been using Docker quite a bit to build customised development environments and tells us about that and there's even some code to grab and some video to be watched. There you go! IntelliJ 15 - both our favourite IDE - is out and sure enough both of us upgraded straight away. It's been a really good experience so far and it's an absolutely worthwhile upgrade. We also briefly discuss Jetbrains' licensing changes and the perception/impact of those. While we're talking about Jetbrains, the discussion moves to Kotlin and to Frege, both reasonably new-ish JVM-based languages. Kotlin is an in-house development of Jetbrains and Frege is more or less Haskell for the JVM. An interesting discussing arose from that - what makes a language a good fit for a certain purpose or audience - and Mark mentioned he saw a talk about "Evidence-Oriented Programming". It's funny how people pretty much "design" languages (and frameworks) by using criteria "I like this" or "This is how I think X should be done" instead of using approaches such as studies, user-tests or other experiments in trying to figure out what works and what doesn't. And while we have this can of worms opened, let's also question that 'computer science' is a proper science. Kai even dug out a 2003 philosophy of sciences paper he wrote during uni while finishing his Masters concluding that computer science overall really is nothing but an engineering discipline and not a science as such. We also briefly talked about Kubernetesa platform to orchestrate DockerBitnami Stacksmith and the need (or non-need) to have Windows Server containers that could run on Docker.  Both of us have been to various events (Mark as part of his job and poor Kai self-funded...) and particular mentions went to Strange Loop, Clojure/conj and CFCamp. Also - if you're interest in presenting at dev.Objective in Minneapolis next year, the call for papers finished on November 29 - that's in 2 days. Nearly last but not least, there's another quick public service announcement for the folks who have a particular interest in Google's cloud platform. Mark's started a Google Cloud Platform Podcast that's worthwhile listening to. Also - this was the first recording we've ever done with Google Hangouts on Air and Zencastr. Surprisingly (after all of Kai's really bad experiences with Hangouts) this worked really well and we might use those platforms regularly now.  Music: "Drop" by TREVVRMUSIC, licensed under CC BY 3.0

Episode 38 - Lucee, the fork and open-source licenses

por Mark Mandel and Kai Koenig

As announced towards the end of our previous episode, this time we had Geoff Bowers on the show. People might know Geoff from things like Sydney's MXDU resp. webDU conferences, him being the benevolent dictator of the Farcry CMS community and other funky ventures. Also, Geoff's current the secretary of the Lucee Association Switzerland (LAS) and that made him an excellent person to talk to about the Railo fork into Lucee. This is essentially what this show is about. There's a lot of discussion around the legalities of the fork and the points that various parties made in blog posts or Twitter comment. But - you really need to listen to find out more about all that. We also talk about a few other bits and pieces, such as open-source licenses in a more general way, how to deal with intellectual property of employees and about some events. Please note that Geoff's audio stream for the first part of the show (until he drops off Skype...) is not the greatest, but it should hopefully still be good enough to get a lot out of it. Sorry for any inconvenience caused.

Episode 37 - California, Lucee, Google Cloud and other things

por Mark Mandel and Kai Koenig

Mark has arrived in California, so we spend quite a bit of time talking about his experiences over there (mind you, it's been three weeks so far). His new job is a Developer Advocate at Google and given Mark's previous excitement about working with Google Cloud Tech over the last 12-18 months or so, it's fair to assume that this podcast is not ending up being more of an advertorial than it always has been. When moving to the cloud, cost is an interesting issue --- and that comes up after talking about Mark's recent move of his blog. For starters, we have a very nice comparison of various cloud technology offerings and their features as well cost. Another big topic is the ongoing discussion about Railo -> Lucee and all the gossip around that. Interestingly enough, Mark has a slightly different opinion on the Lucee fork than I have and we'll elaborate on that during the show. You might want to read the blog post from the "majority shareholder" of Railo and Lucee's response and the summary of their excellent keynote at dev.Objective() to be fully on the same page. We also talked about our ongoing efforts to learn new languages. Kai was playing with Node at dev.Objective() and went through part of the Nodeschool curriculum at an excellent BOF session with Adam Tuttle. Node is clearly an interesting platform, not the least because of the vast amount of available extension modules. Mark has started to learn Haskell in the meantime. We're back in ~2 weeks and our guest of honour will be Geoff Bowers, Acting Secretary of the Lucee Association Switzerland to fill us in more about Lucee. Hopefully by then I've tried Lucee on a Google Cloud Managed VM and can talk a bit about that, too. If you have any recommendations for Android- or general Mobile-development-related podcasts, please leave them in the comments.

Episode 36 - Random things: Rust, Lucee, Android and Fig

por Mark Mandel and Kai Koenig

Oh look, there's another episode of 2DDU podcast... This time we're talking about a variety of things and personal news. Mark's off to Silicon Valley soon, interviewing for a job at Google. Kai's passed all the written exams for his Commercial Pilot License. Each to their own! Rust seems to be a language currently going through some hype and Mark had a bit of a play with it. The verdict: Very fluid and full of breaking changes from version to version at this point, but it also has a lot of interesting features: Algebraic Data Types and an interesting memory model to just name a few. Then there have been some interesting news coming out of the CFML corner. Micha Streit, the inventor and core developer of Railo has forked from Railo 4.2 into Lucee 4.5 and there's lot of good and worthwhile discussion going on over at the new Lucee mailing lists. Adam Cameron's blog posts are worthwhile reading too. Kai has recently started some serious and commercial Android app development and is raving about the experience for while. Who would ever have though that from an iOS fanboy. Getting into Android development coming from a Java background however is very pleasant and Android Studio certainly helps with it. There's also an interesting Mooc on Coursera. We're also briefly talking about DB versioning and were wondering what people do about it in real environments. There are various best practices approaches to it, mainly following the concept of "migrations" from the Rails world, but are there any other approaches? Please provide feedback and ideas in the comments after listening... Mark used Sequel in Ruby-land and we briefly mentioned a book on Continuous Database Integration that has a few interesting ideas, too. Towards the end our discussion swivels towards Docker and Fig. Well, mainly Fig, which seems to be an interesting toolkit to help create customisable and reproducible Docker environments for development setups etc.

Episode 35 - Go(ing) to Go

por Mark Mandel and Kai Koenig

So, we're finally back. Episode 35 is all about Go and we're joined by Marc Esher (who was on the podcast before).  After some a quick run through some "things of today" (that Kai clearly won this time), we get started and try to explain what Go is and its place in the universe of programming languages. We ramble on talking about specific features of the language, what individuals like or dislike about it and how each of us uses Go. Towards the end, we're discussing package management issues with Go but then run out of time to dive into more details and a variety of other topics on our list. However, here's a good amount of links for further reading and on some of the stuff we didn't get to...

Getting started:

Go Packages and Libraries:
  • Package Management: GPM 
  • Generics: Gen 
  • URL routing: Mux 
  • Goon (GAE specific) 

Community:
  • #go-nuts on Freenode (IRC)

Episode 34 - Much Belated

por Mark Mandel and Kai Koenig

So Kai was meant to put this episode up months and months ago, but he decided to go travelling instead and it has languished since then.

So I'm going through the notes now and hopefully I managed to write down everything we talked about.

Kai finished off the Data Mining with Weka MOOC recently, and talks about his experience.

Mark recommends (probably yet again), the A Programmer's Guide to Data Mining online book.

Mark realises he's an idiot when it came to immutability and Clojure, and ends up rewriting his library. See this ticket and this blog post for details.

Mark was heading off to CampJS at the time (yep, it was that long ago we recorded this).

Mark talks about Google App Engine (apparently I'm doing all the talking here). What specifically I talk about I can't remember.  From the notes it looks like Managed VMs and the Asia Pacific data centre.

Kai tries to tie Heartbleed to ColdFusion. It's doesn't work.

I think that about covers it!  I think I'm now going to listen to the podcast again, just so I can remember what we said.

Oh yeah, I'm not unemployed any more, either.

Episode 33 - Stuff

por Mark Mandel and Kai Koenig

This recording was actually supposed to happen before the Holidays. But on the morning, Mark was turned into a domestic goddess for the day by his lovely wife, so we had to postpone. Episode 33 is about "stuff". Among other things we learn that Mark has no bloody idea of proper board gaming and that he thinks Articulate and Risk are good board games. They are not.  (i) Note to myself (Kai): There'll be a board game episode soon.(ii) Note to DianeAmyMark and myself: We need to catchup either in Melbourne or Wellington and play some games. We talk a bit about Go and Core.Async and how to get started with Go and how to run Go on the Raspberry Pi. We also talk about TDD and BDD in CFML because Kai was playing with the new Testbox framework from the team behind Coldbox (Spoiler: It looks really, really good) Finally we also chatted about our conference calendar for the year: Kai:

  • Webstock 2014 (Wellington)
  • cf.Objective() (Minneapolis) (speaking)
  • Scotch on the Rocks (Edinburgh) (speaking)
  • Webinale or Int'l PHP conference (Berlin) (topics submitted)
  • Pycon AU (Brisbane)
  • CFCamp (Munich)
Mark:
  • Lambda Jam AU
  • Strange Loop (St. Louis)

Episode 32 - Stuff we hack on

por Mark Mandel and Kai Koenig

This episode was about random stuff we're working on or playing with when not necessarily coding for money. Some (more or less) interesting stuff we came up with:

Episode 31 - The 2DDU Technology Radar

por Mark Mandel and Kai Koenig

G'day, it's been a while. Today's episode features our first 2DDU Technology Radar. Oi? What? The guys at Thoughtworks have recently gained a lot of well-deserved fame for doing their Technology Radar. It's essentially a structured list of "stuff" to use, look at, evaluate or be careful with when it comes to technology. It contains everything from processes via platforms and tools up to specific technologies and languages. Here's our personal view on technologies: the 2DDU Technology Radar. It's a long episode, nearly 1 hour and 50 minutes. Feel free to agree or disagree with our views in the comments, discussion is very appreciated. If you want to look at the list of technologies we're talking about while listening to the episode you're very welcome to use our published Google Doc to do so. Have fun!

Episode 30 - Broken Code, Rayguns, Enterprise Software and an Ark

por Mark Mandel and Kai Koenig

Today we've been joined by John-Daniel Trask, one of Kai's Wellington-based friends who's also the co-founder of both Mindscape and Raygun.io. Kai admitted that Mark clearly won "thing of the day" this time, but he's already planning his come back from that loss for episode 31 in about two weeks. After this unavoidable business of the day we start talking to JD about Raygun.io, a cloud-based service to track unhandled errors in your software. It's a very interesting product that stands out from the competition (according to Mark's 3-minute market research) by supporting a variety of different technologies as well as looking pretty. The latter triggered a brief interesting discussion on the importance of the user interface, the Novopay debacle in NZ and how enterprise software (the likes of Oracle Forms, Adobe Lifecycle, Microsoft Sharepoint etc) now jump on the HTML5 bandwagon and what we'd expect to happen with that. JD explains the tech stack Raygun.io has been built upon and it's interesting to see that they've used Mono on an AWS infrastructure for the core parts of the backend. While we're talking about AWS, Kai jumps to Glacier and his experience of backing up into Glacier using a Mac OS X tool called Arq. The unavoidable Mercurial topic comes up again as well - Kai's got a Mercurial column in Tweet Deck now that's actively being monitored and JD chimes in that he used to use Mercurial a lot in the past because of the lack of good Git tooling on Windows, too. However in the last 12 months that has changed, in particular because of Github providing a lot of good services (if one is willing to still use the command-line). Side note: Atlassian's SourceTree is available on Windows now, too - only supporting Git (and not Mercurial) at this stage though.

Episode 29 - Back from the Summer

por Mark Mandel and Kai Koenig

After nearly 4 months of "summer break" (yeah, right), we're back. We actually managed to talk about a few really interesting things:

  • Conferences we attended this year (Mark: RubyConf AU, Kai: Webstock) and conferences either or both of us plan to attend. The latter is a rather long: PyCon AU, cfObjective, D2Wc, Strangeloop, CFCamp, Lambda Jam Brisbane and YOW! Melbourne.
  • Distributed Version Control - what's the future of Mercurial (looking at the vast success of Git) and what are the options to host Mercurial in-house after Kiln on premise doesn't seem to be actively sold anymore to new clients
  • IntelliJ 12.1 is out - what's new and which plugins have we experienced to work well/not that well yet?
  • Ruby/JRuby vs. Python/Jython - what's the story with some languages being very popular on the JVM and others not so much?
  • Some CFML-related news: Railo 4.1 beta is out there (and looks great), CF 10 is available on Amazon AWS (finally) and Adobe CF 11 alpha is coming soon.
  • Error tracking with Raygun.io and Mark's efforts in OpenGL and LWJGL.
Here are some more links: If all goes according to plan we're back in two weeks. Have a great weekend!

Episode 28 - Our take on the decline of CFML

por Mark Mandel and Kai Koenig

So we're taking on a pretty controversial topic, but one that has been talked about a lot in the blog-o-sphere, and something we have touched on tangentially in the past. Here is the list of articles we discuss during the podcast:

We talk about our perception of the decline of CFML, specifically in Australia and globally, as well as thoughts on whether or not CFML as a whole can pull out of it, what we think the major CFML backers can do about it, and what we think you should be thinking about as a developer in the CFML community. We expect this to invoke some differing opinions - so while we welcome the discourse, please remember to be civil.

Episode 27 - Live from cf.Objective(ANZ) 2012!

por Mark Mandel and Kai Koenig

In this episode we are joined by the venerable Mark Drew where we talk about his favourite features in Railo 4, what his favourite IDE is and the interesting relationship between Adobe ColdFusion and Railo's CFML engine. It's an interesting conversation all around, and live talks often are, including plenty of audience participation. Kai also admits to his strange relationship with cats. Update from Kai: Towards the end of the episode there's a bit of an uproar in regards to Cats that look like Pinups. Please note that the content might or might not offend you. You've been warned :)

Episode 26 - cf.Objective(ANZ) - Marcin & Phil

por Mark Mandel and Kai Koenig

Today Kai and I were very happy to have Marcin Szczepanski and Phil Haeusler join us for a panel discussion on the topics that they will be presenting on at the upcoming cf.Objective(ANZ) conference. Marcin gave us a quick run through of the advanced feature of FW/1 that he will be showing off, and Phil provided us with a synopsis of his talk on Strategies for effective mobile data communication. The conversation continues into some interesting discussion of mobile native vs. web apps and the various pros and cons. Resources

Episode 25 - cf.Objective(ANZ) Speaker: Kris Korsmo

por Mark Mandel and Kai Koenig

Today we were joined by Kris Korsmo who is presenting at cf.Objective(ANZ) this year on Efficient Coding Using CFBuilder. We talk with him about IDEs, including ColdFusion Builder as well as other options (and we find out that Kai hates VIM). As well as that, we cover Azure, building Windows 8 apps, as well as Mark's new 2560x1440 Catleap Q270 Monitor. Resources:

Episode 24 - cf.Objective(ANZ) Panel: Mercer, Mclean & Turner-Jones

por Mark Mandel and Kai Koenig

As per usual, we are conducting speaker interview for the wonderful cf.Objective(ANZ) conference! On the panel today we have Andrew Mercer who is presenting Work, ReST and Play, about REST based webservices, Justin McLean who is presenting Android Application Development with Java and Richard Turner-Jones who is presenting on Mobile Application development using PhoneGap. We talk to each of them about their history as programmers, and get some of the details on each of their presentations as well. It's a lively discussion, so tune in!

Episode 23 - More Language Exploration

por Mark Mandel and Kai Koenig

We return after a long hiatus with another episode! This episode continues to take us on our exploration of other programming languages. We discuss the work that Mark has been doing with Ruby and JRuby, including integrating it with his ColdFusion project and SOLR as well. This segways into a discussion on Platform as a Service's like Heroku and their position in highly available and scalable applications. Kai mentions some of the issues he was having around databases when he was mucking around with NodeJS, and asks our listeners to comment on any possible solutions they may know about. We make note of the fact that Sean Corfield will in Australia soon, and will be presenting at events in Sydney and Melbourne. Looks like both will be packed houses! Kai took his hand to compiling Railo 4 from scratch, and talks about the issues he faced trying to do that. We also discuss several events that we are attending / attended:

Episode 22 - Clojure and Functional Programming with Sean Corfield

por Mark Mandel and Kai Koenig

We got the wonderful opportunity to talk to the illustrious Sean Corfield this week, which was a great delight and pleasure. Continuing with our exploration of "What would happen if ColdFusion died tomorrow", we explore further into the Clojure programming language, as well functional programming, and Lisps as a whole. We discuss with Sean the reasons behind why you would want to use a Functional programming language, over Object Oriented, the reasons why they have had increasing popularity over the last few years, as well as how you can integrate Clojure into your CFML applications. We also go a little deeper into how you would structure a Functional programming application and the tools that you would use to develop with Clojure. Make sure to check the bottom of this post, we have ALOT of resources to link to. If you have any questions regarding what we talked about on the podcast, please feel free to add a comment, and we'll make sure that Sean notices. Also, if you are looking for a job, and want to work with Mr. Corfield himself, the company he works for World Singles is hiring! Two positions are available:

  1. Back end, data-centric
  2. Front end, design + CFML
Resources We have so many, that it needed it's own section! If you have any more you would like to add, please feel free to add a comment!
