Playing around with kvm, libvirt and related tools to setup an easy to use and quickly available test environment on my workstation. Find out which other tools or environments are available on SUSE side, which can be used instead of a local/private solution.

I like writing little retro games for my kids but these are rarely 'finished'. So I set myself the project of writing a full game in a week, using Lua and targetting the Pico-8 virtual console: HTML5 online playable version:

Hacking on the advanced open source computer algebra system -- FriCAS, which has a long history that dates back to 1965. It has not aged very well: 108 C files has been edited only 66 times in the past decade, and full of compiler warnings;

I'd like to explore a very popular desktop Linux distribution from last year -- the Steam Deck OS. It is said to be immutable, so I hope to get some inspiration from it to help our ALP.

Build an open-source appliance editor for SUSE Studio that interacts only with the API, using modern JS web frameworks. For users, this provides an opportunity to influence, or create unique tailored editing experiences for Studio appliances. For Studio maintainers, this provides a road towards a modern appliance editor, and a chance to remove tens of thousands of lines of brittle legacy code. For hackers, this provides a chance to get your feet wet with modern client-side web technologies, like

Basically, I want to continue to what I did last time (link). Back then I got some really good results, but I didn't quite make it to a state in which the application is totally useful.

The disassembly in gdb is not ideal. The binding with source code lines is weird (even crash, which does use gdb beneath, does that better), I don't see the jump targets; furthermore, there's a lot more informations hidden in the DWARF2 which may be of some interest - like which code is inlined, or which register/stack address should contain some variable. My goal is to search for a way how to improve that.

Firebird Emu is a third-party multi-platform emulator of the ARM-based TI-Nspire™ calculators. Currently it does not run that well on Android and iOS, which I want to change during this hackweek.

What is Openspace? Starting on Kickstarter and Indiegogo as Openbook Open Source Social Networking Service got recently renamed to Openspace (still reachable via openbook.social though). This network wants to protect its users privacy and make the world of SNS a better place.

Project Description

Update Linux training manuals that were created in 2011 under a CC share-alike license for opensuse. In 2011 Inwent, GIZ and FOSSFA created training material using the LPI exams requirements. This project is to update the content of that manual.

Since this will be my first real "from the start" publication the goal for me has more to do with the experience of publishing the projects, use of the public hosting site and access tools, particularly git. The projects that will be published are:

Project Description

Utilize eBPF for network policy in (nested) virtualization environment.

SELinux Common Intermediate Language is a language that allows the creation of SELinux policies. Some of the traditional constrains (tight coupling, nested optionals, ...) are lifted or not as problematic. http://github.com/SELinuxProject/cil/wiki/

Today OpenQA mostly runs on virtual machines, but it can get really tricky to find bugs triggered by real hardware. There are only few interfaces required to interact with a machine though: 1) HDMI<br>

The goals: - Learn enough Java fundamentals to understand OpenDaylight code

Currently the main complaint people have about OCI tooling is the lack of a transition from Docker to OCI. With umoci you have a lot of low-level image configuration abilities, and skopeo and runC cover the other major parts of the picture, but you need something to tie them together. I'm not going to be implementing YAWAR (Yet Another Wrapper Around Runc). It's just going to be a single script that can take a Dockerfile and create an OCI image that is basically the same as the Docker image you would get -- with the big difference being that you didn't need Docker and everything used the OCI. The other cool benefit of this is that you could build images without privileges (since rootless containers now exist in runC and in umoci).

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: - Apache HttpAsyncClient

This project is a POC to create an iSCSI driver for the Ceph backend for Cinder. There are a few use cases that would make it nice to be able to attach a ceph volume as an iSCSI target.

Sometimes open source products lack of a good and inspiring documentation. So my idea is to brush up my Blender skills to a level that I'm able to do some tiny 3D animations to explain workflows and procedures better.

Project Description

QEMU can serve host files using the 9P2000 protocol. Xen can serve host files using the 9P2000 protocol. Even WSL2 can serve files using the 9P2000 protocol. This makes it a perfect choice to make your kernel under development in your host environment available to your testing VM, right? Well, almost. GRUB2 cannot boot from a Plan9 filesystem share.

The open-iscsi package is the de facto standard Linux iSCSI initiator, but it does not support iSCSI MCS. MCS stands for multiple connections per session, and it means that the iSCSI initiator and target communicate over multiple connections to increase throughput. It is sometimes written as "MC/S".

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

I have a broken disk - it has a broken head and I have a replacement disk with the head I want to transplant. I already tried head transplantation on old not needed disks. Those that only head 1 arm were doable with straw method, but this disks has 3 arms so I need a tool to hold the arms in place.

Project Description

The folks at Asahi linux have been working on porting linux on the Apple Silicon. In a recent blog post they announced they will be joining forces with Fedora on releasing a Fedora Asahi Remix. I would be happy to see this level of collaboration between Asahi and openSUSE community, too.

In case any of the source files changed, openSUSE Build Service rebuilds the dependent packages regardless of whether that particular modification affects the dependency. This makes our resources footprint bigger (and the electrical power bills higher). It also affects users, because every new package build causes the package manager to include that package in the next update thus consuming network bandwidth and resources of users' computers.

Current OBS controls for package rebuild triggers

Often when we test maintenance updates or when we decide to push an update for a package we want to know what that change may cause. Right now it is really difficult to figure out what package depends on a given package.

Motivation

The Firefly-RK3288 is the first SBC with the Rockchip RK3288 SoC, the first available chip with Cortex-A17 cores (32-bit ARMv7). I received such a board just in time for Hackweek Interstellar and will be looking into booting an upstream kernel with openSUSE 13.2/Factory rootfs.

I intend to learn little bit around apache httpd, get acquainted with some native modules as well as look at apache2-debugging-modules package.

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.

Project Description

Our SUSE Support knowledge base sucks. It has a clunky UI, only has a What you see is what you (don't) get editor, doesn't show version history. I hate it, you hate it, and our customers hate using it and would rather pick up the phone and bother us.

CalDAV [1] and CardDAV [2] are client/server protocols designed to allow users to access and share calendar and contact data on a server. There are many CalDAV and CardDAV clients around, e.a. Thunderbird/Lightning and also free CalDAV and CardDAV servers like Baïkal. With that project I want to create a client in PHP to be able to create and modify data in calendars and addressbooks from websites.

The Inforce Computing IFC6540 is an SBC with Qualcomm Snapdragon 805 SoC (32-bit ARMv7). I had previously brought up openSUSE on the IFC6410. A week before Hackweek Interstellar I got the IFC6540 to boot on serial console using the upstream-based Linaro integration branch, up to searching for the rootfs. Since USB and SATA support were still missing, my goal will be to prepare a MicroSD based rootfs to complete the bringup.

Using docker as a development platform for nontrivial development environments sounds interesting. This project is about learning basic docker handling, about exploring how to use it for simplifying development, and maybe (but just maybe) about providing ready-made docker containers for new team members.

This involves customizing a tumbleweed image to configure cloud-init and adding other elements like docker, kubernetes, etcd, flannel which are required to get a kubernetes cluster running either using kiwi or disk image builder.

Picotm is a system-level transaction manager. It provides transactional semantics to low-level C operations, such as modifying data structures, (some) file I/O, memory access. Picotm also handles error detection and recovery. It's fully modular, so new functionality can be added. For the Hackweek, I want to dedicate some time to picotm. I want to finish some of the refactoring work that I have been working on. If there's time left, I'd like to investigate two-phase commits and how to support them in picotm.

Create a graphic scene where I can see a cube and maybe add to it some textures or modify its geometry.

Write a tool to generate documentation (README.md) from chef cookbook attributes files including the comments that describe the attributes. The goal is to use this with the openstack chef cookbooks from https://github.com/stackforge/ and maybe integrate it the upstream Gerrit as a Jenkins job. The project is hosted at: github/mapleoin/chef-attrdoc

> [arbs] is a tool for keeping an OBS project in sync with an ArchLinux package repository. More specifically, I use it to sync [home:roman-neuhauser:arch-community][h:rn:ac] with [community.git][c.git], a mirror of the actual svn repository underlying community. arbs already exists but has many rough edges. the goal of this hackweek project is to make it resilient in the various failure scenarios so it can be used in a truly unattended fashion.

kCFI is a tool that enables the compilation of commodity Operating Systems with Control-Flow Integrity protection. kCFI first prototype was developed/implemented during a PhD program held in the University of Campinas, in Brazil. Although fully functional, the tool remains in a very experimental shape, needing to be refactored prior to being released. As kCFI consists in multiple tools, which include compiler plugins, kernel patches and binary analyzers, its deployment is considerably complex. Once code refactoring is finished, the next step consists in setting up proper repositories for the tool and for each submodule, along with scripts and documentation to enable easy configuration and compilation on new environments.

Create a tool which will make it possible to monitor the lifecycle of pods in a kubernetes cluster (as well as other types of tabular or structured data), and provide a convenient user interface for viewing and interpreting that data. This will be useful in development and testing of our kubernetes-based container platform (Cloud Application Platform), as it will allow us to better understand where things are going wrong when we encounter component failures. * Github

openQA currently supports different architectures: x86(_64), ppc64le, aarch64 and s390x. In this project I would like to add support for RISC-V[1]. First emulated ontop of x86, like we previously did with aarch64. As openSUSE images for that processor are already generated, it could be useful to do some basic automated tests on them.

Project Description

This project aims to recreate a small computer game that we played in highschool; it was called "Slime Games". However it ran as a Java applet and so no longer exists on the modern web.

The Nvidia Jetson TK1 is an SBC with Nvidia Tegra K1 SoC (quad-core Cortex-A15, 32-bit ARMv7). I have openSUSE running on the Jetson TK1, but KVM is currently not usable as the CPUs are not booted in HYP mode. Thierry Reding of Nvidia has some work-in-progress for U-Boot and upstream kernel that I would like to test.

ARM64 is become more popular on different markets, but obviously lots of pepople didn't have the hardware platform, and fastmodel is helpful for people to play with ARM64 environment, furthermore, we can run different software platform on it, such as Cloud, HA, Virt and OpenStack.

During hack week I will carry on the research I started to write my thesis. The work is called "Turbulence Driven Clustering in Nematic Active Particles" and will (hopefully) make it into a Physical Review Letters paper.

I have several themes in progress, they all need lots of work before they could be used with openSUSE. * The gtk people keep changing things so the gtk theme I use to match my enlightenment theme also needs fixing.

Currently we use openQA for the the YaST integration tests. It runs YaST in a VM and controls it via emulating keyboard input. The result is checked by comparing the screenshots. This approach has several disadvantages:

Rust Emacs clone (sort of), see README for details.

There are issues with S3 and S4 handling in a KVM SLES or openSUSE guest. I'd like to figure out what's going wrong and get things fixed as much as possible.

Although there isn't much demand right now, it won't be long before >256 vcpus in a KVM guest will be desired. Currently, due to 8 bit apic ids only being used the limit is 256. Implement the x2apic infrastructure that will allow QEMU + KVM to break the 256 vcpu barrier.

Using NFC(Near field communication) tag / phone Lock and Unlock ( replace password login ) on openSUSE with Gnome.

The Allwinner Tech Optimus Board by Merrii is the evaluation board for the Allwinner A80 SoC with big.LITTLE Cortex-A15/-A7 configuration (32-bit ARMv7). The sources leaked from Allwinner contain GPL violations in U-Boot and Linux kernel and therefore won't easily build with openSUSE's armhf gcc (binaries seem to be softfp).

Packages added by the dependency solver in order to resolve a user's request, are marked as having been automatically installed. They may later be removed, if no more manually installed packages depend on them (e.g. by zypper remove --clean-deps). However things may go haywire. Automatically installed packages may turn out to be useful, and you may want to exclude them from any automatic cleanup. And vice versa.

While it is important for package maintainers to track the upstream code base activities and backport significant patches in a timely manner, it could be a tedious work when there's hundreds of packages in a project (ahem, GNOME) to follow manually. So I wish to get mail notifications when new commits with certain keywords (e.g. SIG, {crash, hang}{s, ing, ed}, leak(age), CVE-, https://bugzilla.gnome.org/show_bug.cgi?id=*, etc, etc) come in.

During the previous Hackweek [0], I have successfully implemented, tested and merged [1] an implementation of the entire C++ standard header <future>. This time, my aim is to modernize the C++14-esque standard library [2] of HelenOS [3][4] with a C++17 feature - the <filesystem> header. The <filesystem> header is much larger than the <future> header which I barely managed to implement and test in the allocated time for the previous Hackweek, but <future> was mostly OS-independent as it relied only on previously implemented features of the standard library. The <filesystem> header, however, is limited by the filesystem API of the OS and as such implementing of the entirety of it might not be possible, limiting the scope of the project (which is a good thing due to the time constraints). The primary features of the header [5] that should be implemented:

Project Description

Time Slider is a Solaris feature, which utilizes ZFS to provide a graphical way for restoring individual files from automatically scheduled snapshots. Since we have btrfs on SLE/openSUSE now it's probably an interesting project to implement something similar.
