  • Managing my personal knowledge base

    January 5, 2020

    As software engineers, we create various resources by documenting issues, submitting bug reports, writing notes, creating documentation, and so on. The sum of all these resources can be called a knowledge base. In this post, I document how I use Notion, GitLab and other software to maintain my personal knowledge base.

  • Reading List (Organizing Knowledge)

    January 5, 2020

    Introduction Knowledge management is an important topic for a software engineer. I have always been interested in material on the topic. When I decided to write an extensive post on my system and workflows, I started to collect sources and similar articles. To avoid further blowing up the original post, I will cover these sources in this separate post. There is a vast amount of resources covering specific tools and usage examples.

  • People to follow on Twitter who actually tweet about Software Engineering

    November 3, 2019

    I believe that Twitter is a solid tool to stay aware of current discussions and trends in software engineering. In this post, I present a list of manually selected Twitter accounts who tweet regularly about software engineering or closely related topics.

  • Copy-paste ready commands to set up SGE, PBS/TORQUE, or SLURM clusters

    October 18, 2019

    Local HPC clusters continue to play a vital role in scientific research. However, setting up those systems can be very painful. If you just want to play around with the different systems, spending several hours until you can submit your first job is a very bleak outlook. Therefore, I present copy-paste ready instructions for setting up SGE, PBS/TORQUE, or SLURM on a single machine, which will act as the master and a compute node at the same time. All guides are tested on Ubuntu 18.04, but should work with little modification on most recent Linux installations.

  • Reading List (August and September 2019)

    September 30, 2019

    Starting with today, I will regularly present blog posts, articles and other online resources that I think are worth a read. My selection criteria will be somewhat arbitrary. In general, I will share content that I think contains valuable information for a large spectrum of software engineering professionals. Additionally, I will provide short summaries for all the articles I post.

  • Setting up a Linux Workstation for Software Development

    August 13, 2019

    In my opinion, Linux is the best operating system for a software engineer, except they develop explicitly for Windows or macOS. Still, as with any other operating system, optimizing a Linux workstation for software development requires some configuration. In this post, I will present tools and concepts that I think are very helpful, but overlooked by many.

  • Using Hugo, GitLab Pages, and Cloudflare to create and run this Website

    June 1, 2019

    In this post, I outline how I develop and run this blog site. I briefly explain my technology choices and give detailed instructions about how to use the resulting stack to create such a project. If you stick with me until the end, you will know how to run a beautiful, easily customizable static website for free.

  • High-performance Computing with AWS Parallelcluster

    May 7, 2019

    AWS ParallelCluster is a toolkit for automating the process of building, configuring, and managing clusters of virtual machines on the Amazon Elastic Compute Cloud (EC2) cloud. These clusters can be used similar to traditional HPC clusters. This post contains a short performance analysis based on literature study and provides detailed instructions for getting started with your first cloud cluster.

  • Nitrite as embedded NoSQL Database for Java

    May 6, 2019

    This post introduces the Nitrite NoSQL database system and explores its applicability for Java desktop applications. Furthermore, I describe an example application using Nitrite as a backend data store for a generic JTable, where rows can have an arbitrary amount of attributes.
