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. Ceph's librados library provides an API for the storage and retrieval of arbitrary key-value data via the omap functions. A watch/notify protocol is also provided as a mechanism for synchronising client state (locking). Key-value data stored in the RADOS back-end inherits the same redundancy features as regular objects, making it a potentially good candidate as a replacement for CTDB in scale-out Samba clusters.

My previous knowledge about Python is small. I need learn more about python. Using a script write in shell script, andt this script already ported to python by a collegue team. I'm going to use a port of this script to understand and maybe collaborate with this code.

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. Technology: HandleBars.js or similar, plus some YAML technology

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. The purpose of this project is to learn to create such galleries, the best would be to add social features of flickr directly there, like comments or faves.

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. The project started in Hackweek 16 (fall 2017) and has been worked on since, both in Hackweek 17-19 and outside. First two parts of kernel implementation are in mainline since 5.6-rc1, first part of userspace implementation (ethtool utility) has been submitted to upstream at the end of Hackweek 19 (2020-02-16).

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

Ai and Machine learning play important role in our life, I'd like to learn it. research to see is there any way of using DEEP learning on open source stuff.

Hackweek 18 Update

What Has Been Done During HackWeek 18

Mottainai - Task/Job/Build Server for everyone!

Written in Golang. You can find the source code on GitHub and docs here.

I have been known to talk anybody I held presentations with into using odpdown. That was always a little awkward, since it started off with pip install odpdown, rather than zypper install odpdown. I want to fix this awkwardness and package odpdown properly so it can be installed as a RPM package. I'll also include the auxiliary infrastructure I've added around it over the years (various Makefiles and scripts for generating transcripts from comments) to the package so others can benefit from that stuff, too.

What is meCoffee? The meCoffee is a small PID that can be used to upgrade an Espresso machine with some new features. It supports mostly the Rancilio Silvia. The initiator of meCoffee is starting to Open Source his work and has already done so by opening up the meBarista application for Android, iOS and Chrome.

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. The potential area where this idea could have positive implications are:

To ease debugging cgroup relates issues this suggests to: - list cgroup hierarchy tree(s),

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. This project has the goal to test out an automatic way to transform the Suse Manager UI into a Single Page Application.

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. For Hackweek 18 I want to separate the interpreter from the GUI so that QLogo can be run from the command line or from a shell script.

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. Consolidate all this by taking the good benchmarks and implement new ones where needed, such as message queues, everything around the 'perf bench' framework. This will both improve the lives of us who hack on kenrel ipc as well as improve coverage overall. Eventually mmtests should be updated as well.

There are various email synchronization programs like offlineimap or mbsync, which have some inherent limitations: - mbsync does not support IMAP IDLE

Let's make reposync faster

Every day,

During the last year Askbot, a question and answer oriented internet tool, similar to stack overflow has been tested for internal usage. The testing went well and it was decided to use the tool in a larger scope.

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. Reference: Collectl's HelloWorld module, turbostat
