Ceph, ELK & opensuse
This talk will be held by Denys Kondratenko and Abhishek Lekshmanan to talk about Ceph and ELK (Elastic Stack) integration and current status on openSUSE (Leap and Tumbleweed).

presented by Denis Kondratenko

Ceph is a distributed storage platform that is contender to become the future of software defined storage, providing unified access to block, object and file interfaces. However like any complex systems there are various subsystems that may fail and analyzing logs is generally the first line of action. This is where the ELK stack comes in, to search, analyze and process logs and metadata.

We could probably...

Libabigail: How semantic analysis of C and C++ ELF binaries can be used to analyze ABI changes

Libabigail is an infrastructure for semantic analysis of ELF binaries containing C or C++ programs. It powers command line tools like ‘abidiff’, which let users compare ABI changes between two different versions of a given ELF binary by analyzing just the binary and its ancillary debug information.

The result of the binary comparison is a kind of hierarchical ‘diff’ which shows changes up to...

What should we do about Containerised Applications?

presented by Richard Brown

Containerised Application technologies like AppImage, Snappy and Flatpak promise a brave new world for Linux applications, free from the worries of shared libraries and dependency issues. Just one problem, this is a road long travelled before, such as in the application dark ages of Win32 applications and DLLs. And it worked out so wonderfully there... Do we risk a future where, like the resurr...
