Let's use the Hackweek to improve Ruby, the programming language I use every day. It is while using a language when you can realised that things that need/can to be improved, so there are many things that only Ruby developers can raise up. Also, getting involved in the development of Ruby will help to get a better understanding of how it works. So I will take my ideas/concerns to the Ruby community and implement some of the them in the code of the Ruby core. Ruby features and bugs are tracked in https://bugs.ruby-lang.org/projects/ruby-trunk/issues

An initial prototype from the last hackweek can be found on YouTube Some may know the reality TV show shark tank where entrepreneurs pitch their startup ideas to get an investment. There is a German franchise of this show called "Höhle der Löwen".

Yes this project is yet another project for creating a Suse Manager clone. The motivation for that comes mainly from my need for a simple suse manager that i can easily run at home without the massive overhead involved in suse manager setup. Also since i mainly need to manage opensuse machines most of which are tumbleweed, suse managers repository model does not really work well in that case.

Mottainai - Task/Job/Build Server for everyone!

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

Use this hackweek to practice and learn more about Go.

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.

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.

Customers are using complex storage stacks such as LVM over dm-crypt over MD RAID over multipath over iSCSI and FC with LOTs of LUNs, and we're facing problems in that area which are usually very hard to reproduce. It's also hard to guard against regressions. Being able to quickly and reliably set up VMs with various types of storage / multipath is a key part of testing multipath. It's doable, but cumbersome and has a steep learning curve. I want to create easy-to-understand manual recipes plus scripts that are both easy to understand / customize and deploy.

Hackweek 18 Update

What Has Been Done During HackWeek 18

Try to get back an automatic email notification about new or changed SAP Notes. Since SAP has closed down some of their internal servers, which hosted an unofficial database/API to the SAP Notes, the nice email notification service of the SAP LinuxLab is terminated.

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).

2019

I promised to start this project way earlier, but I think Hackweek will be a great time to make a start. The project once was called $BABELFISH, later "Rumsfeld", to honor the creator of the "Unknown unknowns" meme, now it's name is Maxfeld.

There are a couple of interesting initiatives that make the openSUSE project interesting for SMB, such as

The Invis Server

Oficina, a mechanical workshop application developed in Qt/C++ Hackweek 17: Work on TODO - Test. Make it very stable, after that, insert it in openQA.

There is a super cool framework for mobile phone apps available: ionic (http://ionicframework.com/) ionic allows you to write apps in HTML, (Angular) JavaScript, and TypeScript for any mobile phone platforms: iOS, Android, and Windows Phone. You just need to know how to use HTML and JavaScript and you can start writing an app and convert it to any mobile phone platform.

The idea is about an easy way to allow users to make upgrades (e.g.: changing from one major version like 15.0 to version 15.1) using a GUI and as easy as they can in Ubuntu. Something like a notification with a button to perform the upgrade with just one-click, instead of having to deal with the terminal, that frights some new users and gives them the sensation of an outdated system.

Description

It can boot up from udisk/floppy.

The software is a rails app with an Angular.js frontend using the gphoto2 library to trigger a Nikon D60 camera. Features: take pictures, browse pictures, automatic upload to a gallery (tumblr, flickr, owncloud), qr code for download,

Make a final attempt to implement a graphical user interface for grub2 (gfxboot2).

It's quite some work, unfortunately. Here's what's done so far:

This is the tool I've been working on since HW11 and it needs more work. Actually, there's always something which could be done on it. It is basically an x86 instruction decoder with special emphasis on the kernel and decoding interesting pieces of it in order to help in the development of low-level patching techniques, among others. git repo: https://gitlab.suse.de/bp/x86d

New Development In previous hack weeks, the first few days ended up being wasted on just getting it working. I'm pleased to share that the code quality has improved dramatically since the last hack week and there are now extensive test cases for both unit testing and testing against real vmcores, and we'll use both mypy and pylint (if installed) to perform static analysis. Packages for those are available in openSUSE or as part of the crash-python OBS repo for SLE15. It has been tested with kernels from 3.0 to 5.1.
