Ceph offers a highly scalable and fault-tolerant storage system. Samba is already capable of sharing data located on the Ceph Filesystem, however scale-out sharing (the same data exposed by multiple Samba nodes) currently requires the use of CTDB for consistent and coherent state across Samba cluster nodes. In such a setup CTDB provides a clustered database with persistent key-value data storage and locking. Database usage is abstracted out via a generic dbwrap interface.

My previous knowledge about Python is small. I need learn more about python.

The goal is to create a set of YAML files describing L3 supported products with all metadata we need to store there - and a JS presentation layer automatically showing this data in several forms, one of them will be a part of our L3 documentation.

Flickr provides not only a large space for photos but also nice features around, including tags and other metadata allowing sorting of photos by different criteria - but one is very limited in the design of something like "frontpage" of such galleries. The solution is to use 3rd party JS solutions using Flickr API, like nanogallery.

There seems to be an overall consensus that the ioctl interface used by ethtool is a poor design as it's inflexible, error prone and notoriously hard to extend. It should clearly be replaced by netlink and obsoleted. Unfortunately not much actual work has been done in that direction until this project started.

I would like to dedicate my time to the improvement of the Czech localization of KF5.

Ai and Machine learning play important role in our life, I'd like to learn it.

Mottainai - Task/Job/Build Server for everyone!

I have been known to talk anybody I held presentations with into using odpdown.

What is meCoffee?

The idea is to explore the technologies and the various components to realize some AI to predict pitfalls in source code which can potentially generate run-time misbehaviours.

To ease debugging cgroup relates issues this suggests to:

The experience while navigating throughout the UI of Suse Manager it's not that nice. Whenever we navigate to a new page, the whole page gets refreshed and recreated, even when half of it didn't change a thing, for instance, the menu, topbar, and the notifications WebSocket connection, which in my opinion doesn't provide a smooth experience.

QLogo is a UCBLogo-compatible implementation of the Logo language using Qt and OpenGL. QLogo was designed with the language interpreter integrated into the GUI.

The state of the art of sysv/posix ipc benchmarking is a combination of ad-hoc programs scattered over the internet. While some mechanisms, such as sysv semaphores, have a lot of coverage, others really lack (message queues), and some are simply non-existent; albeit some of the legacy flavors we aren't too concerned with, other than them being functionally correct.

There are various email synchronization programs like offlineimap or mbsync, which have some inherent limitations:

Let's make reposync faster

During the last year Askbot, a question and answer oriented internet tool, similar to stack overflow has been tested for internal usage.

Currently the CPU subsystem of Collectl can get the CPU loading but no CPU power state. My idea is that tracing turbostat then developing a collectl module to get the CPU power state. It can be used to monitor C-state or frequency.
