Yey! I got to do it again. For the 4th time in the history of this weird thing called the Graphistania podcast, I have had the change to spend some quality time talking to Emil Eifrem, our fearless leader and CEO of Neo4j. As last time, we actually recorded the video, so you will find the zoom call, and the MP3 version of it, below in the blogpost - along with the habitual transcription.
Hope you will enjoy the chat as much as I did.

Hope you are all well, keeping safe, and finding some time to relax and enjoy life in this wonderful rollercoaster that is 2020. Think of it this way - we will never forget this ride, EVAH!
As you can imagine, things have been evolving at warp speed in the wonderful world of graphs as well. So me and my partner in crime Stefan had another chat about all the things we have seen pop up, mostly through the awesome This Week in Neo4j (Twin4J) newsletter. Here's the chat we recorded:
Here's the transcript of our conversation:
RVB:00:00:01.448 Hello, everyone. My name is Rik, Rik Van Bruggen from Neo4j, and here I am again recording another episode of our Graphistania Neo4j podcast. Wonderful time of the day to start with this type of conversation because I have my dear friend, Stefan, on the other side of this call. Hi, Stefan. How are you?

As we enter November 2020, I - like many people I assume - can't help but feel quite "betwattled" by all of the events taking place this year. I took some time last weekend to look at all the crazy events that happened ... starting with pretty normal January and February, moving slowly to ominous March, and then living the weird, (semi-) locked down lives that we have been living until this very day I write this, which is the day after the bizarre US elections.
In any case, I decided to have some fun while reflecting about all this. And in my world, that means playing with data, using my favourite tools... CSV files, Google Sheets, and of course, Neo4j. Let me take you for a ride.
Starting out with my calendar
The starting point of all this is of course my Google Calendar - which is buried in online calls and meetings these days.

So here's the chat that we recorded about the new book - hope you enjoy it as much as we did.
RVB - 00:00:00.151 Hello, everyone. My name is Rik, Rik Van Bruggen, from Neo4j, and here I am again recording another episode of our Graphistania podcast. And this is a special one. This is a special episode, one that we've been talking about for some time, because I have a very special guest on this show, and that is my dear friend and colleague Jim Webber. Hey, Jim.

So of course I had to take this data for a spin myself - it seems really important to me that more eyeballs are looking at this, and more people exposing the sometimes very questionable behaviour of the world's largest financial institutions.

One thing I do know though, is that very smart and loveable people, in my own social and professional circle and beyond, seem to be confused by some of the data. Very often, they make seemingly rational arguments about the numbers that are seeing - but ignoring the fact that we are looking at an Exponential Growth problem. In this post, I want to talk about that a little bit, and illustrate it with an example from the Neo4j world.
What is Exponential Growth exactly?Let’s take a look at the definition from good old Wikipedia:
Exponential growth is a specific way that a quantity may increase over time. It occurs when the instantaneous rate of change (that is, the derivative) of a quantity with respect to time is proportional to the quantity itself. Described as a function, a quantity undergoing exponential growth is an exponential function of time, that is, the variable representing time is the exponent (in contrast to other types of growth, such as quadratic growth).The basic functions that are being entertained here are very simple in terms of the maths:
