Projects in the topic java
Java is a class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible.

I want to continue my work on this feature for a CAT (Computer Aided Translation) program, OmegaT. When translating a segment (usually a sentence), I would like OmegaT to automatically replace all words it finds in an active glossary by their translations. This will save the translator some time.

The project aims at kick-starting an Android application to manage libvirt-based VMs and containers. The libvirt build on android expedition has already been completed during hackweek 10 and refreshed here. Which leaves for hackweek to use libvirt-java bindings to use it.

Apache Maven is a build tool used by many Java projects, which is incompatible with OBS in that it tries to download binary dependencies from the Internet. Several people have in the past years tried to somehow bootstrap Maven and failed.

In SUSE Manager we want to offer support for bootstrapping systems that don't have the salt-minion installed and configured yet. This can be done using salt-ssh given just a hostname, username and password. See the docs about salt rosters for even more options. What we are missing:

This project is about using Salt SSH for managing systems without the need of an additional agent to be installed (besides sshd). With the SSH protocol the connection is initiated by the management server, thus Salt SSH can be used to even manage systems that are located outside of company firewalls, i.e. machines that cannot access a salt-master due to firewall restrictions.

There is a number of possible improvements to the architecture of SUSE Manager / Salt integration that should be investigated in order to improve the reliability and scalability of the backend:

The purpose of this project is to implement an Android application which shows some images (or dice) which you must use to create a short story.

There is a couple of libraries available for asynchronous and non-blocking processing of HTTP requests (in Java) that can be used to avoid having threads waiting for responses in request intensive applications, for example:

Many of the Uyuni / SUSE Manager web UIs are still based on the no longer maintained Struts framework (version 1.2!) and implemented as JSP pages, while we added newer features based on the Spark framework and React. For me there is a vision of using only one technology stack (especially just one web framework, frontend framework and template engine) eventually, so it is about time to get rid of the old stack. While this is surely a huge effort, why not start with a new login page and then go from there rewriting other pages one by one?

At SUSE/openSUSE we are using (at least some times) Etherpad, whose functionality is really limited and looks as taken from the past. After taking a look to other possible Open Source alternatives, I think there is at the moment any which offers all the feature I would like to have. Because of that I would like to contribute to JetPad, with the idea of using it privately and that it can also be used by SUSE/openSUSE.

For years we have been discussing the idea to modularize SUSE Manager. This would enable developers to create their own extensions to SUSE Manager without needing to touch the core repository.

Simplify the codebase by using a more modern toolkit to accelerate maintenance and future development.

There is a number of annoyances and pending improvements when working with the Salt Formula for provisioning Prometheus Exporters in Uyuni:
