Acting as Teaching Assistant in Optimizing Apache Spark™ on Databricks Course

I joined Databricks as a Lead Instructor under Brooke Wenig. We knew each other for a long time so when she asked me one day if I’d been interested in teaching courses in Databricks Academy and keeping my “employment independence”, I thought no minute and accepted the offer. Apache Spark™ Programming with Databricks (2 days) I was…

Fireside chat with Ali Ghodsi

Thanks Ali Ghodsi for being so open, honest and developer-ish during our fireside chat last night (Poland time). I really enjoyed it very much and hope for more similar chats in the future. I was nominated to the Databricks Beacons program almost a year ago (which I consider similar to…

The Meetup is Dead, Long Live the Meetup!

The Internals Of Apache Spark Has Moved

To Different Organization and GitHub Pages — For now… Until I figure out how to make all “The Internals Of” online books available under a single root domain, e.g. books.japila.pl.

Giving up on Read the Docs, reStructuredText and Sphinx

tl;dr Stay away from Sphinx and RST. I’m coming from Markdown and Asciidoc markup languages and can’t think of any reasons why I should keep writing documentation using reStructuredText (RST) markup language. After just a couple of days I felt as if I was going backwards. I’m quite surprised how…

Je parle français

I speak French. Not really. But I will soon. I wish I could write “I learn French” actually, but that’s something I haven’t learned yet during my lessons. I use Duolingo mobile app and I enjoy it a lot. It gives me all I wanted for a French novice like…

Here comes Apache Kafka Workshop in Warsaw Poland

That’d been not so long since the first workshop with Apache Kafka and Kafka Streams when I was asked to run a workshop with Apache Kafka. I’ve had more and more workshops with Apache Kafka recently (mostly for developers), but the recent inquiry was completely different — I had to…

My very first Kafka Streams Workshop

I could not have dreamt of a better shout-out after my recent work with Kafka Streams that I’ve just received from the one and only Gwen Shapira from Confluent (the company behind Apache Kafka and Kafka Streams). I’m an independent consultant specialising in Apache Spark with some focus on…
