OSCON Austin 2017 – Keynotes & Sessions

Continuing my previous post from Tuesday, the last two days of the conference were keynote speeches and talk sessions. I am not going to discuss every session I attended as there were many, I’ll just hit the ones that were the most interesting for me.

To give you an idea of how many sessions there were, look at the image below. Every hour there were 14 different sessions to choose from! And of course as you would know it, the ones I really wanted to attend most were all at the same times and my current employer didn’t pony up the big bucks to get me access to videos of all of the sessions, so I was forced to choose.

14 Different Choices Every Hour


So the beginning of days 3 and 4 were keynote addresses, 6 on Wednesday and 4 more on Thursday. Unfortunately O’Reilly only posted excerpts for most of the keynotes on their YouTube channel. To see the whole videos you need a Safari subscription. I’ll include the ones with the full videos below.

Christopher Aedo from IBM discussed open infrastructures and defaced numerous classic paintings.

Ying Xiong, the Chief Architect of the cloud platform at Huawei Technologies, spoke about the open source ecosystem. This was very interesting to get a different point of view from China.

Finally I hate to include this one but I will anyway since the whole video is there and there is some useful information in it. Alvand Salehi, a Senior Technology Advisor at The White House, discussed open source from the U.S. Government, even some code from the Pentagon.

So that aspect was interesting. It was just unfortunate that I felt like I was buying a used car.


There’s nothing like the Family Truckster


Over the 2 days I attended 12 sessions, and there were 3 that stood out:

“From REST to GraphQL: Why a query language is perfect for writing APIs”

I could really beat myself with a wet virtual network cable. I got to this one late. It was the first one after the keynotes and I spent some time in the Expo Hall and lost track of time. The room was packed except for some seats up front (I don’t see why 50 people or more were just standing up in the back when there were seats up front). It was hard to see the screen but it was well worth it.


The session was taught by David Celis and Garen Torikian of GitHub. They tag teamed the story of a fictional company called Welp and their need to develop a REST API. After documenting the inherent problems of REST they decided that they needed to use GraphQL instead! What followed was a really good live demo along with tons of great details.

I know that when I get to the point of building out my API I will be spending a ton of time going through their slides and examples. Really great stuff. Thanks guys!!

Slides (with notes!): From REST to GraphQL

UPDATE: They provided the video to their session! Now I can see what I missed and everything else as well!

“The serverless revolution for JavaScript developers”

This presentation by Pam Selle (and her blog), a software engineering lead at IOPipe, didn’t have much new for me that I hadn’t already heard at ServerlessConf or earlier at OSCON, but it was by far the best talk to describe and detail what serverless is and what the different options are if you want to go down this road.

If you aren’t really sure what this thing called serverless really is, go through her slides. I wish her presentation video were available as well because that makes it so much more clear. Definitely a good read and a good resource. Thanks!

UPDATE: Pam provided the video to her session!! Thank you!!

“Graph databases will change your freakin’ life”

This was an excellent talk on Graph databases bu Ed Finkler, the CTO at Graph Story. After attending that workshop by William Lyon two days earlier my interest was intense and this talk didn’t disappoint. One thing that does disappoint is that his slides were not posted afterwards 🙁 (By the way, most of the slides to the talks can be found here).

UPDATE: He provided the slides!! Also, I found a video of him making a similar (or possibly the same) presentation previously and here is the video (embedding is turned off).

His talk covered a lot of the same material that the workshop did, but that only served to deepen my understanding of it. Plus seeing how someone else used Cypher and Neo4J really helped my understanding.

Definitely check out his non-profit organization called OSMI which stands for Open Sourcing Mental Illness. Ed is doing some excellent work. Give what you can to help. I did!

Also, he has provided an example repo in Github called 2016 OSMI Survey Graph. Check it out! I plan to.

OSCON Austin 2017 – Workshops

Recently I posted about my experience attending the Serverless Conference in Austin at the end of April. Two weeks later I attend OSCON in Austin as well. OSCON stands for Open Source CONvention and is put on by O’Reilly.


Got there early, waiting for the keynotes to begin.

The convention was held over 4 days. The first two days were workshops, 2 a day. The last two days were a combination of keynotes and hour long talks. I really would have preferred that the workshops came at the end instead of the beginning, but this was just as good I guess.

Given the vast amount of information I received over these 4 days I’ll split this into two posts, this one will be on the 2 days of workshops, followed by one post on the 2 days of keynotes and talks.

Day 1

Workshop 1:Building, deploying, and running a scalable and extensible serverless application using AWS

The workshop was taught by the two founders of Symphonia, an expert Serverless and Cloud technology consultancy based in New York City (Make sure to get their free e-book “What is Serverless?” available on their website now). John Chapin and Mike Roberts tag teamed the workshop to great success, leading us through a lesson on what exactly serverless is, talking about AWS, Lambda and Java, and then finally taking us through a tutorial.


They planned their course well as we learned a great deal without feeling overwhelmed (at least I didn’t). Having already attended workshops and sessions at the Serverless conference two weeks prior probably helped me a great deal in understanding.

One way this workshop was different though is that the code was all in Java and used Maven. The workshop I attended at the Serverless Conference used NodeJS and npm. I spent 8 years as a Java developer, I even taught Java at the college level a couple of semesters way back right after I finished Grad School in 2000. It all felt very familiar which was wonderful.

I had a chance to talk with John Chapin briefly at both conferences. I didn’t get to talk with Mike Roberts but I did get to see him speak at the Serverless Conference. They are both very knowledgeable and easy to talk with.

I look forward to contacting them for advice and guidance as my business develops. Thanks for a great workshop!

Workshop 2: “Building a deployment pipeline with Jenkins 2.0”

This workshop was on a topic I felt I should know or at least be exposed to more, mainly for my current full-time job that pays the bills, and possibly for myself down the line. The workshop was taught by Brent Laster who was obviously well versed on the subject.


Sitting a little too close!

Unlike the previous workshop, this felt like a double-barreled fire hose. We went through topics and exercises quickly and I was doing what I could to keep up. When I get into that mode I am happy when I complete the tasks and keep up, but I really don’t learn anything along the way.

After a bit he said that he designed this course to have as much information as possible so we can learn it afterwards on our own time and have a lot of reference material. While that is nice to have after the workshop, during it I felt I was getting very little out of it. I would have rather gone at a slower pace during the class and had more time to digest so I would retain more. Now I just have a bad taste in my mouth about it and will only go back to the reference material when I need to.

He did mention this book above, Continuous Delivery, as the main source of his material for the workshop. I provide a link here as a first attempt at monetizing the site a bit. 🙂 Every penny helps!

Day 2

Workshop 3: “Power Git: Rerere, bisect, subtrees, filter branch, worktrees, submodules, and more”

So my first workshop on the second day was a lot like my last one from the day before. Something I felt I should know more about though I wasn’t that excited about it. Git however is something I do use every day and maybe I could get more out of it if I get to know it better?


I picked a better seat for this one.

The workshop was taught by the same person who taught the Jenkins workshop, Brent Laster, so it was a very similar format. I’m more familiar with Git so it seemed more like a single-barreled fire hose than a double. This was also a bit more straight forward as well.

He mentioned a book where he got a lot of material for the workshop, and this time it is a book he wrote himself!

Work through the labs if you want to learn more about some higher level functions of git. I don’t ever need them with the work I do, but it’s nice to be a little familiar with them and to be able to quickly look up what I need.

Workshop 4: Building a real-time recommendation engine with Neo4j

My final workshop was my biggest surprise. I knew what I was getting with the first one and was excited about it, the next two were all about acquiring necessary knowledge, but the last was just something that I thought might be interesting.

I honestly hadn’t thought about it much going into it. I got what I was looking for with the first workshop and felt numb after the next two, so when I walked in to this one I had a blank slate. No expectations.


Sat way too far away for this one!

The workshop was taught by William Lyon from Neo4J. We first got into what the Graph Database Model is and how it differs from relational databases. The idea of nodes and relationships instead of tables and rows really fascinated me. The more we learned the more powerful I realized this format was.

Then we started to get into the query language for Neo4J called Cypher. This took a while to get used to. I have spent a lot of time writing SQL queries over the years, but Cypher takes a shift in thinking. By the end I felt I was really starting to catch on.

He pulled data from the Meetup.com site for the Austin area and we were able to query it. I’m a member of a few (though like an idiot I never go) so I was able to query myself.

We did all of this querying in the Neo4J sandbox which uses the Neo4J browser and it has an amazing interface. I really fell in love with using it. I want to find a use for it just so I can use it (actually I am sure I’ll have a use case for graph databases soon enough). I really look forward to going back through all of this and exploring further when I get to that point in my app development. Thanks William for a great workshop!
