Podcast Interview with Tomasz Bratanic

This following podcast recording is an funny one. First of all because it took me and Tomasz like 3 retries and multiple scheduling rounds to get this thing done - and secondly because of who Tomasz is and what he is doing in our graph community. As you will read below, Tomasz is nog just a novice to Graphs - he's a novice to IT in general. A year ago, he was still filling his days with online poker - and now he is implementing and enhancing some of the coolest parts of Neo4j's APOC libraries. DEFINITELY worth a listen - it's an inspiring story.

Podcast Interview with Chuck Calio, IBM

Last year at GraphConnect San Francisco, we had this great announcement where we were having some of IBM's most senior leaders, Doug Balog, talk about what they were doing together with Neo4j to let the graph database perform like crazy on the Power8 hardware platform:

Doug came on stage and talked to Emil and the audience about all the hard work that was going on there, and now, just before GraphConnect New York - it felt like the right time to check in with friends at IBM to talk about their work with Neo4j and how that might affect the Graph community. So we got Chuck Calio to spend some time with us on the podcast - and here's our chat:

Podcast Interview with Kevin Madden, Tom Sawyer Software

OMG has summer flown by. It has been a fantastic season over here in Europe, with lots of great family time and lovely trips to different destinations across Europe - I had a blast.

However, the downside of all this fun has been that I have really not had the time or inclination to publish more podcast episodes. In fact, I have to apologize to the guest on this episode that I am publishing today, the super-smart and fun Chief Software Engineer of Tom Sawyer Software, Kevin Madden - because I actually recorded this episode back in June already!!! Seems like an eternity ago - but at the end of June I was just really running short on time, did not find it possible to publish the interview then, and then... summer sunshine got in the way.

But hey - better late than never! So here's a great interview with Kevin - as you would expect, he has many great and interesting perspectives (pun intended!!!). Here's our chat:

Podcast Interview with Sébastien Heymann, Linkurious

As I am coming up on my 5th anniversary working for Neo4j, I am increasingly happy, proud and thankful for the journey that we had - and the many great people that I have met along the way. One of these people is FINALLY appearing on this podcast, and has a history with this blog every since the VERY first article that I wrote in january 2013: in this article, I showed folks how to load the Belgian Beer Graph into Neo4j using a tool that was actually not intended for this use: Gephi. Many beer (related article)-s later, I am now finally talking to Sébastien Heymann, founder and CEO of, and one of the main people behind Gephi at the time. Here we go:

Podcast Interview with Steven Baker, Neo Technology

About a year and a half ago, at some meeting in Malmö at Neo's Swedish HQ, I bumped into a new colleague there who was... a little different than most Swedes. He was a bit louder, a bit more outspoken, unapologetically sarcastic, VERY funny - and a big fan of all kinds of (Belgian and other) beers. So we started talking - over a beer. I think it's fair to say we hitted of - and I got to know this Canadian-gone-Swedish guy a bit more, talked more, drank more, ... and decided to invite him to talk about some of the interesting stuff that he works and worked on for our podcast. His name? Señor Baker. Senior Baker. Srbaker. Also know as Steven Baker - working for Neo. Here's our chat:

Podcast Interview with Darko Križić, Prodyna

Another stupidly late podcast publication on my behalf. Somewhere early March (yes, I KNOW - dammit!!!) I had a great conversation with one of our prime Neo4j partners in Germany and across Europe these days, called Prodyna. We did a couple of events together, and I found that some of their thinking and case studies really aligned very well with my own. So we got together for a chat. It's a bit annoying because both of us were referring and looking forward to GraphConnect - and I clearly missed that deadline/timeline. But still wanted to share the conversation... Here it is:
 As per usual, here's the transcript of our conversation:
RVB: 00:02.689 Hello, everyone. My name is Rik, Rik van Bruggen from Neo Technology, and here we are again recording another podcast, a little bit closer to home. It's actually a really special podcast for me because it's exactly two years ago since we started it on request or instigation of my dear friend Michael Hunger. And this week we've invited someone from Germany in order to talk a little bit about of the wonderful things that PRODYNA is doing with Neo4J. And that's Darko Krizic from PRODYNA. Hey Darko, how are you?

Part 2/2: looking at the Web of Belgian Public Companies in Neo4j

Yesterday, I published part 1 of this short little blogpost on how we could load the dataset of a great newspaper article in De Tijd (our local financial/economic newspaper) into Neo4j. Of course, the whole point of that loading process (all of which is easily copied from github, btw) is to be able to do some additional querying on the dataset - just because we can :) ... So let's do some simple queries here, and then you can of course explore this some more yourself!

Start with some simple queries

In the article above, one of the key figures in the web of public companies, is Luc Bertrand, the CEO of Ackermans & Van Haaren - a former dredging company that turned into a holding company. Let's explore the network around him - by walking the paths from his node for three hops.
//network around Luc Bertrand 
match path = (m:Male)-[r*..3]-(n) 
where contains "Bertrand"return path
That query gives us a nice little graph that we can explore:
