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!

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.
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.
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.

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.

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.

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.

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...
Go Packages and Libraries:

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.

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 Diane
and myself: We need to catchup either in Melbourne or Wellington and play some games.
Finally we also chatted about our conference calendar for the year:
- 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)
- Lambda Jam AU
- Strange Loop (St. Louis)

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:
Finally, vote for cf.Objective() 2014 topics:

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!
