Open Source im Blickpunkt der Politik (Video, in German)

In diesem kurzen Video erkläre ich die Bedeutung der Softwareindustrie für die Wirtschaft eines Landes und wie Open-Source-Software diese stärken kann. Es richtet sich an Public-Policy-Maker und alle interessierten Personen.

Die englische Version dieses Videos folgt; die Folien wurden vom FAU Sprachdienst aus dem Englischen ins Deutsche übersetzt (und von mir nachkorrigiert).

Neben obigem Youtube embed gibt es eine werbefreie Version auf der FAU Website sowie eine runterladbare Datei.

The slides are also available (English only).

Single-Vendor Open Source Firms and Intellectual Property Strategies (Video)

In this video, I explain the single-vendor open source business model (also: multi-licensing, open core) and in particular its intellectual property strategies. This talk is partly a reaction to the recent licensing changes by commercial open source firms and the resulting confusion. An upcoming article will go into more detail next year.

Next to the Youtube embed, there is also an ad-free version courtesy of FAU, my main employer, as well as a simple download available. Fast forward to the slides as well.

Enabling Open Innovation with Open Data using the JValue Open Data Service

Today I gave my JValue Open Data Service talk at USM (University of Sciences, Malaysia, at Penang). I am grateful for the opportunity and the recording.

Abstract: Open data has the potential to create significant practical value for its users through open innovation. Yet, to realize this value, we need an open ecosystem, next to open data, that allows app developers to create that value. In this talk I present my view of this open ecosystem of open data and how it should be structured. I then present the JValue Open Data Service (ODS), an open source software under development at my research group, that provides a key piece of this ecosystem. The goal of the JValue ODS project is to enable open innovation through app developers.

Single-Vendor Open Source at the Crossroads (Slides) #lfosls

I’ll be giving a presentation on single-vendor open source today at the Linux Foundation Open Source Leadership Summit 2019.

Abstract: Most venture capital funding in open source flows to single-vendor open source firms. With the struggles over licensing in the cloud, these companies find themselves at the crossroads: Stay true to open source or move to proprietary licenses, abandoning the goodwill and opportunities that come with open source? In this talk I will review how this business model works, discuss the challenges posed to vendors by large cloud providers, and review the options on the table.

If you liked the slides, you might like the paper as well.

Next up: Why now? And who? The struggle over single-vendor / open-core licensing.

Ten Years of Inner Source Case Studies (Video)
