I’ve had a draft called “Is scrum the best we can do” lying around for months and the chance to finish it is tiny. So I decided to extract parts of it: Some thoughts on whether sprint commitments are beneficial or not.

TL;DR: Maybe, it depends.

This is a short introduction on how to apply a bit of performance theory in the context of tuning insert throughput performance in CrateDB.

Ask a question regarding the performance characteristic of some piece of code on the Internet and you’ll end up reading an answer along the lines of “premature optimization is the root of all evil”.

I’m starting to get sick of reading those answers. Optimizations aren’t evil.

Or how Crate uses Elasticsearch.

Most people who know Elasticsearch think of it as a search engine, and they’re probably correct. But we at Crate think about it a bit differently and use it as a framework.

In this post I’ll try to explain how that works.

In this post I’ll describe how to set up the audio system that has been doing its work happily in my living room for about a year now.

IPython is a more powerful interactive shell for python.

In this post I’ll explore some of my favorite IPython features.

In this article I’ll show you how HTTPS traffic from a virtualbox guest vm can be routed through mitmproxy in order to sniff HTTPS traffic.

This might be useful, for example, if you wanted to figure out how a JSON API works that you know an application that you’ve installed uses.

At Crate we’ve recently introduced something that we call “Funday”. It is probably similar to what Google has been doing with their “20%” time. In this Post I will take a deep dive into the Crate core and explain how I used that time to build an auto completion mechanism for SQL statements.

In this post I’ll take a look at how to get started with D-Bus using Python and systemd.
