Immer mehr Konzerne gehen aufgrund der Rechtsunsicherheit im Bezug auf rückwirkende Sozialversicherungspflicht keine Verträge mehr mit Freelancern ein, sondern beschäftigen externe Mitarbeiter nur noch über Arbeitnehmerüberlassung (ANÜ). Hier stelle ich einen Ansatz zur Berechnung eines Gehaltsäquivalents auf Basis eines Stundensatzes vor.

The gradle wrapper can download and verify a specified version of gradle for a project without the need of a local gradle executable. The gradle documentation suggests to check it into the VCS (version control system, e.g. git). This article discusses the advantages and disadvantages of keeping the gradle wrapper in a VCS and presents an alternative.

COBOL (COmmon Business Oriented [programming] Language) dates back to 1959, and is still used in its realm of business software, mostly on mainframe computers. Of course, there are also many related software modernization and migration projects. Thus, once in a while even non-mainframe developers might need some COBOL knowledge. Commercial COBOL systems, especially on real mainframes, are expensive. In this article I demonstrate how to set up the GnuCOBOL compiler and integrate it with Visual Studio Code on Ubuntu Linux, but it also works on Windows and macOS. This way, experimenting with COBOL becomes easy and cheap.

Using snippets from compilable source code files in prosa documents is a great approach. By doing so, I can make sure that the source code actually compiles. By adding unit tests, I can even make sure it does what it’s supposed to do. I knew such is possible with AsciiDoc/AsciiDoctor, but does it also work if AsciiDoctor is run via JBake?

Finally, I had enough time to migrate my website and blog from WordPress to JBake, a static website generator written in Java. In this article I explain why I switched the technology and how I automatically migrated my contents – conversion-script included.
