An experimental tiny WM of Wayland an idea by NalaGinrut Wayland would replace X11 in the future (maybe soon?), we're researching/learning Wayland. And I planed to try a tiny Window Manager of Wayland for a practice. It's meaningful I think, since there's little independent WM for Wayland, except for Mutter which is a part of Gnome desktop environment. Updated almost 4 years ago. 3 hacker ♥️.

Make spiv full featured image viewer and release GFXprim RC1 an invention by metan Description The RC0 release is out since the last hackweek see GFXprim pages. From that point 187 patches with various fixes, new features and new tests went in. New features includes support for various file formats, fixes and enhancements in python bindings, speedups, CMYK support, better documentation and more. Now it's about the time for RC1. Updated about 6 years ago. No love.
Improve linuxrc/rescue system a project by aginies <p>Rescue system has a lot of options , but most of them can only be set at boot time, first idea is too provide a way to configure them while the system is running.<p> some ideas Updated almost 4 years ago. 5 hacker ♥️.
Continue on osc3 porting an invention by mvyskocil Preface In a previous hackweek project (https://github.com/SUSE/hackweek/wiki/osc3%3A-port-osc-to-Python3) I have converted osc code to Python3. This has triggered quite some weirdness regarding plugins, but osc is usable from python3. Or it was, not sure if more recent changes did not break the compatibility. Updated about 6 years ago. No love.
Implement BREAK for pseudo-terminals a project by ptesarik This will greatly enhance the usefulness of QEMU virtual serial ports, because the Linux kernel interprets a break on the serial console as a SysRq, but there is currently no way to pass this signal over a pseudo-terminal. Updated about 1 year ago. 5 hacker ♥️.
Twopence an invention by e_bischoff Twopence is (will be) a remote execution engine for tests, able to run tests in virtual machines and real hardware through various means of communication : virtio for KVM / QEmu, ssh on top of libssh, serial lines. This library can be called from shell and ruby wrappers. While it is already functional (and used), it still needs polishing, stabilizing, and extending. It is also planned to integrate it with Pennyworth (project Machinery) and let it go fully Open Source. Updated almost 4 years ago. 7 hacker ♥️.
Voxel exploration game an invention by KGronlund The idea is to play around with a minecraft-like block exploration game, written from scratch in C using SDL2 and OpenGL 3.0. Minimal dependencies, probably won't be a game as such before the end of the week, but the goal is to have a world generated and to be able to walk around in it. Why? Mainly to refresh my 3D knowledge, catch up with what's happened since I last played with that stuff, and to have fun. :) * Source code Updated almost 4 years ago. 1 hackers ♥️.
Make ruby-ui usable for YaST an idea by dmacvicar ruby-ui was a hackweek project with jreidinger to make libyui (YaST text/graphical engine) usable from pure-ruby without going through YCP. We experimented a bit extreme trying to make the usage of SLIM templates possible. It kind of worked. Updated about 3 years ago. 1 hackers ♥️. Has no hacker: grab it!
Support for WiFi-enabled Canon cameras in gphoto a project by michal-m I have a Canon PowerShot S120, which allows for browsing / copying photos over WiFi. There are apps for Android, iOS, and Windows to do that. The protocol uses upnp to discover the camera and the smartphone/computer and them some HTTP-based protocol. I have some code using libupnp for the discovery and a perl script that is capable of transfering one file, but it's far from complete. Plus, I need to refresh my memory, because the last commit is from January :-(. Now, there seems to be some support for such cameras in gphoto already. So the plan is to dive into gphoto and use what I learned about the protocol to fix the gphoto support. If you own some other WiFi-enabled Canon camera supported by the CameraWindow software, let me know. Updated about 1 year ago. 4 hacker ♥️.
Enhance kdumpid an invention by ptesarik The kdumpid tool can be used to determine the kernel version from a crash dump. Some useful features are missing: - support for new compression methods (lzo, snappy) Updated almost 4 years ago. 1 hackers ♥️.
SMBIOS 3.0 support in dmidecode an invention by jdelvare On February 12th, 2015, the DMTF released version 3.0.0 of the System Management BIOS Reference Specification. This update isn't just adding enumerated values to existing structures, as previous updates did. It is also introducing a new entry point format which allows for larger tables and structures. Support for this needs to be added to dmidecode. Additionally, reading the entry point and the table from /dev/mem is no longer possible on all systems, so some work is in progress to offer an alternative interface through sysfs. It would be great to finalize this and release a new version of dmidecode that would support both SMBIOS version 3.0 and this new kernel interface. Updated almost 4 years ago. 2 hacker ♥️.
Protect disk devices from concurrent use in the libvirt libxl hypervisor driver a project by jfehlig The libvirt qemu hypervisor driver has long supported protecting disk devices from concurrent use via libvirt's lock manager interface. Xen used to support the same functionality in the old xend toolstack, but dropped support in the new libxl toolstack. The Xen community decided, rightly so, that this functionality is best provided by a higher-level management tool, e.g. libvirt. This project aims to provide integration between libvirt's lock manager and the libxl hypervisor driver, essentially reintroducing support for disk device protection in the Xen management stack. Updated almost 4 years ago. 1 hackers ♥️.
Bring Linux memory scanner scanmem/GameConqueror to openSUSE an invention by sparschauer All other distributions have scanmem/gameconqueror packages. scanmem is a command line memory scanner to locate variables in memory and GameConqueror is the Python/GTK3 front-end for it which also provides game trainer features. But it is not only a game cheating tool. It can also help testing applications, debugging memory issues, watching variables in memory or it can be used for reverse-engineering. Hackers also use it for things like ping spoofing. As the upstream maintainer of this tool I'd like to bring it to openSUSE and maintain it there. Updated about 1 year ago. 5 hacker ♥️.
Improve openvswitch+libvirt+Xen a project by jfehlig openvswitch is used by cloud infrastructure (e.g. OpenStack) and software defined networking stacks, often in conjunction with KVM and Xen compute resources. When creating workloads on KVM compute resources, orchestration services can specify the openvswitch interfaceid and port-profile of the workload's virtual interface(s). E.g. orchestration can create workload configuration containing Updated almost 4 years ago. 3 hacker ♥️.
Add a ncurse UI to wireshark an idea by aaptel Wireshark has a CLI program called `tshark` that can dump the dissectors raw (or xml) output. It would be nice to have complete curses wireshark UI, either by reusing tshark xml output or by making another ui program. Updated almost 4 years ago. 3 hacker ♥️. Has no hacker: grab it!
Secure keyboard an idea by mwilck This idea was inspired by the recent discussion on the "talk" mailing list about the (in)security of the German ID card. The Chaos Computer Club and other researchers claim that the ID card is insecure. Actual attacks that have been demonstrated are based on keyloggers. Keyloggers might be the biggest security threat for Linux users at this time. Keyloggers are trivial to write for Linux and readily installable, and a keylogger with normal user rights may read root's password. One might ask "Why are we caring about local root exploits at all as long as users run stuff like sudo in X terminals"? Keyloggers can even read the input from devices like the Yubikey. Updated about 3 years ago. 3 hacker ♥️. Has no hacker: grab it!
OTR (Off The Record) plugin development with libotr5 for encrypted chat a project by whdu To implement OTR function on IRC client, to make chatting private. pure-python-otr (potr) has lack of maintenance for a long time and been considered as "potentially insecure". So I will call libotr5 directly with C. Updated about 1 year ago. 6 hacker ♥️.
Improve C/C++ skills an idea by pvorel I'd like to improve my C/C++ skills with contributing small easyhacks to some open source projects (kernel's kconfig, git, util-linux, fluxbox, libreoffice, ...). Updated almost 4 years ago. 1 hackers ♥️. Has no hacker: grab it!

Shell completion an idea by federico3 Implement shellcomp Command line (aka tab) completion is popular in the Unix world as it helps typing speed, prevents typos and makes the shell more user-friendly. Updated about 3 years ago. No love. Has no hacker: grab it!
netlink interface for ethtool a project by mkubecek 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). Updated almost 3 years ago. 4 hacker ♥️.
Boot system from Ceph RADOS Block Device an idea by dmdiss Write a new Dracut module which adds support for booting a system where the root filesystem resides on a remote RBD image. * Pack keyring and ceph.conf (monitor address) in the initramfs image Updated almost 4 years ago. 3 hacker ♥️. Has no hacker: grab it!
Add Ceph support for Azure RESTful protocols an idea by dmdiss Microsoft Azure offers a bunch of interesting RESTful protocols, providing access to objects (Block Blobs, similar to S3 Objects), disk images (Page Blobs) and file systems (Azure Files). The underlying services seem to map pretty closely to RADOS, RBD and CephFS respectively, so adding support for these protocols to Ceph, despite being a lot of work, should be relatively straightforward. I've already worked on implementing a C client for these protocols via Elasto, so it might be worth reusing the same code in implementing the server functionality atop the public librados / librbd / libcephfs libraries. The other option would be to use civetweb/rgw, which is already embedded within Ceph for S3/SWIFT gateway support. Updated over 5 years ago. No love. Has no hacker: grab it!
Make parted great again! a project by sparschauer During regular L3 work I often don't find enough time to work on the command line disk partitioner parted which I maintain. Changes often directly affect yast-storage(-ng) and libstorage(-ng). @aschnell opens bugs faster than I can solve them. Upstream is often slow and often wants patches differently. Updated about 1 year ago. 1 hackers ♥️.
L3: Improve crash-setup, develop a core-setup a project by sparschauer The current crash-setup source is located here. Pretty much is working nicely but it doesn't care for the debug source making it impossible to use the `crash> gdb list *<symbol>` command right away. This is bug 997558 which should be worked on.
