Klaus Rechert's Blog
In the previous blogpost we focussed on the preservation of Virtual Machines. In the second part we focus on the preservation of a computational scientific workflow implemented in a common workflow engine as a software container. Container technology (also called operating system virtualization) is promoted as a lightweight alternative to virtual machines, requiring less resources […]
This blog post is introducing CiTAR – Citing and Archiving Research, a three year Baden-Württemberg state project, which is developing infrastructure to support computer assisted research. One major outcome of this project are means to publish, cite and provide long-term access to virtual research environments.
In the previous blog post we have introduced the Docker-based EaaS Desktop application and we have briefly showed how to create a new disk image and install an operating system. Since an installation “from scratch” is not always possible or desired, EaaS supports importing existing disk images from various sources.
Emulation-as-a-Service (EaaS) has successfully evolved from the bwFLA project since 2011 and is now in production use. However, setting up a new instance without help of the developers was challenging if not painful. Thankfully, a DGF/NEH grant enabled us to work on usability, documentation and novel workflows, to enable a wider audience to use emulation. […]
On June 24th 9.30 AM EST Dragan Espenschied, Digital Conservator at Rhizome NY, released an editorial on rhizome.org featuring a restored home computer previously owned by Cory Arcangel. The article uses an embedded emulator powered by the bwFLA Emulation as a Service framework and the University of Freiburg’s computing center. The embedded emulator allows readers […]
With the bwFLA Emulation-as-a-Service you can enable users to view your (interactive) objects without actually giving the environment+object to the user. This is a nice feature, especially for dig. art and similar: you can provide access to an almost unlimited amount of people being able to view, use and interact with a piece of dig. […]
It has been quite some time since the last update of the bwFLA demo instance. Sine then we have significantly improved usability and added a lot of new and hopefully useful features. With a first complete implementation of ingest and workflows it is time to release new version of the bwFLA framework. Preliminary notes: Please […]
Finally, a first semi-public demo instance is available to the OPF community. The current version features – an overview on basic emulation services; different emulator + OS platforms are available for testing. The next bwFLA release will feature a sophisticated user management, i.e. users can start with a base image, clone this image as a […]
We are currently preparing for the OPF Hackathon from Nov. 13 to Nov. 15 in Freiburg i.B., Germany. To provide you all with a preview of what to expect in the practical sessions we have set up a demo-server hosting our emulation framework. Currently we support about 10 different hardware/operating systems combinations covering MacOS 7-10, […]
