Talk at the University of Augsburg about practical use cases of NoSQL

Image
It was a pleasure visiting the university of Augsburg last week. Prof. Dr. Michael Predeschly invited me to give a talk about practical uses cases of NoSQL. It was amazing to see all those interested students and to answer their questions about polyglot persistence, the right usage of NoSQL databases, and practical use cases. Do you want to know more? Then reach out to me. My contact details can be found here: https://www.nosqlgeeks.de .

NoSQL Geeks is part of the Stückwerk Community

The Stückwerk Community is a project of the "Kult E.V." in Krumbach (the home town of the company NoSQL Geeks). The idea is to create a place where culture meets social initiatives. There are frequent events like art exhibitions or intercultural meet-and-greet-s. NoSQL Geeks will present during this year's XMas market that happens in the Stückwerk building in the town center. More about NoSQL Geeks can be found here: https://www.nosqlgeeks.de . / Das Stückwerk ist ein Projekt des Kult-Vereins in Krumbach (der Firmensitz der NoSQL Geeks). Die Idee ist es einen Platz der Begegnung von Kultur und sozialen Initiativen zu schaffen. So gibt es z.B. Veranstaltungen wie Kunstaustellungen oder interkulturelle Treffen. NoSQL Geeks wird sich wärend des diesjährigen Weihnachtsmarkts im Stückwerksgebäude im Stadzentrum vorstellen.

So what exactly is an Event Loop?

Introduction Most of you are knowing that I am working a lot with Redis. And some of you might also know that Redis OSS 'standalone' is mainly single-threaded. The reason why it can achieve that high throughputs on a single instance is that it uses an event loop. But what the hell is an event loop and how does it work? First of all, let me tell you the story behind this article. It all started last weekend. For some reason, I found the time to read a Kotlin book. Not sure why I did, guess I just had the feeling that I am too long disconnected from actual development tasks and wanted to explore one of the comparable new programming languages. The book was great and I had the impression that Kotlin is actually quite nice. Then I went back to my main task (helping to enable the Technical Field at Redis Labs) and had to work on a slide about the Redis event loop. A look at the source code (and the following article https://redis.io/topics/internals-rediseventlib), raised a ques

A simple but special Redis Web Client

It was a while ago when I wrote my last blog post. So let me take the chance to write something about a very simple piece of software which started as a fun project of mine. Let's do it a bit different this time. I will show you the results first and then I will explain what's special about this application: This looks very basic, right? What's special about it? So here is the story behind it: It all started a few weeks ago when I decide to buy an iPad Pro (11 inches). The motivation was indeed not to use it as a development machine. My current role requires to draw some diagrams and to explain stuff a bit more vizually. So the iPad Pro seemed to be a nice device for such a purpose. Being a techie, I wondered a bit which kind of development can be done on it and I started to install some tools for experimenting with them: Working Copy: A Git client Pythonista: A Python IDE StaSh: A shell for Pythonista which allows you to use packages via 'pip' Blink:

Building a Recommendation Engine with Redis

When I was asked which topic I would like to present at this year's OOP conference, I was out of the box thinking about 'Something with Machine Learning' involved. It was years ago at the university when I had a secondary focus on 'Artificial Intelligence and Neural Networks' and I think that's fair to say that the topic was not as 'hot' as it is today. The algorithms were the same as today but the frameworks were not that commodity and calculations happened either on paper, with MatLab or with some very specialized software for neural network training. However, the actual discipline stayed fascinating and even if I would not call myself a Data Scientist (I sticked more with my primary focus which was Database Implementation Techniques - so I am more a database guy :-) ) I am really amazed of the adoption and number of arising frameworks in the field of Machine Learning and Artifical Intelligence. Machine Learning or Artificial Intelligence is quite a
