mailprocessing performance improvementsan invention by jgrassler I maintain the mailprocessing utility, a Turing complete maildir and IMAP capable filter with rules written in Python, both upstream and in openSUSE. It is currently suffering from some performance problems I'll devote my Hackweek (or part of it) to improving. Most notably the following areas will need some attention:

Terratest playgroundan invention by szarate Few weeks ago whilst analyzing the possibility of using Terraform[1] via terraform-libvirt [2] plugin, I came across Terratest [3], which is an automated testing framework.

SUSE Manager for Retail Instructional Video Tutoriala project by lkotek The goal of this project is to create video tutorial describing configuration of SUSE Manager for Retail.

libpathrsa project by cyphar The plan is to implement a safe path resolution library for Linux to avoid the plentiful numbers of security vulnerabilities that have been seen in the wild related to path resolution race conditions and various other attacks. I've been working on kernel-space solutions but even if they were merged, it is difficult to use them safely directly. So this library intends to provide simple wrappers that everyone can use.

Simplify implementations of lockless printk ring bufferan invention by pmladek There are attempts to solve some kernel deadlock with using lockless printk ringbuffer. The proposed implementation is pretty complex (6 stages, 6 write and 6 read barriers, two buffers, entries linked via list, ...)

Integrate Bard with MusicBrainz and implement a proper web interfacea project by alarrosa My music manager, Bard, was improved in the last hackweek with a very simple React-based web interface but I didn't like the result at all (basically, after learning React I noticed I didn't like it and all the dependencies and the complexity it added) so since then, I've reimplemented the web interface using just jQuery. Also, in the last months I've added musicbrainz data structures to the database (which was also ported to use Postgresql) to prepare bard to use MusicBrainz's data. I also stopped using other python libraries to read audio files and use the ffmpeg libraries directly instead with a c++ wrapper implemented inside Bard which is much much faster.

Extract lead and cycle times from Githuban invention by jochenbreuer When all of the SUSE Manager squads switched from SCRUM to a Kanban we lost estimations and therefore also the ability to do predictions. But there are other ways to get insights that are even more reliable, since they are based on anecdotal data. The lead and cycle times of issues are the two most important here.

CUPS: Generic "monitor" wrapper backend to monitor the actual backendan invention by jsmeix Create a new generic CUPS wrapper backend /usr/lib/cups/backend/monitor that runs in parallel with the actual backend to monitor it.

obsci - a CI for open build service packagesa project by tbechtold Currently it's pretty difficult to create tests for some specific package. So something like TravisCI for OBS would be good.

From bare metal to virtualized Kubernetes cluster with just Salt and Redfisha project by joachimwerner My goal is build on Alberto's work on "yomi" and the new Salt-based virtualization management features that Cedric has contributed, then combine them with a Redfish prototype to do the following from one (ideally idempotent) Salt state (orchestration state if required):
