Crash Reference Card for ARM64

an idea by ptesarik

Update the Crash Reference Card, replacing 32-bit x86 with ARM64. The above link contains all sources I used to create the original card.

Biofeedback / Neuroscanner / Dreamanalyser

an idea by chuller

This project is based on some hack of a mind flex toy containing a so called "neurosky eeg" chip. Having a sensor connected to your skull this system can meassure several waves emitting from the brain, also called brainwaves. The Idea is to combine this system with some camera based monitoring system that will watch a test subject while sleeping and recording the corresponding brainwaves for later analysis of brainactivity and body movement. Other use cases do exist, this was the only one i could come up with that involves sleeping in the office ;)

desktop saver

a project by psladek

The idea is to produce a standalone, independent tool to save and restore windows positions and sizes, analogous to a similar feature in KDE desktop. This would be handy in various lightweight desktop enviroments.

"emerge" for rpm/SUSE

an idea by dmacvicar

There are lot of packages that can't be hosted on the Build Service. The idea would be a tool where you can say:

SSDBoost

a project by hrommel1

If you want to use the full potential of SSDs as primary (and possibly only) storage on SLE or openSUSE systems, you are supposed to perform several configuration settings to make it fly, including: - changing the io scheduler of the device to noop or deadline

play with Coccinelle and lock checking

a project by mhocko

We had a quick course of Coccinelle during the last Labs conference. The tool is really great and I would like to explore possibility of checking lock invariants for particular functions. Julia was really prompt and implemented something that should help but I didn't get to it since the conference.

try to understand cups > 1.5

a project by mhocko

Starting with CUPS 1.6 things have changed considerably. Clients are no longer discovering broadcasted printers anymore. Distributions (e.g. Debian) has backported the original protocol into cups-daemon package but this doesn't seem to work either on my laptop. I would like to look and try to understand what the hack is going on here. The outcome should be my understanding of the change and how to configure CUPs to behave reasonably again.

understand and possibly improve cscope

a project by mhocko

cscope is a great tool index C/C++ sources and allow to navigate through the code. I have learned that the project is mostly dead and what is worse it uses its own database format to store the index. I would like to see some extended functionality in the tool - e.g. search whether a function A is reachable from B, filtering search results per-file, fix functions with function parameter detection (such functions are not recognized properly currently) and some others. See if the cscope specific storage can be replaced by a more generic database (sqlite?) and understand how the code flow works so that new extensions would be easier to implement.

finish de-l3slaveing of crash-setup

a project by mhocko

The primary motivation for crash-setup (created by l3team) is to make kernel crashdumps deployment and crash using as easy as possible. This has been the case for quite some time except the tool was quite l3slave centric. With a great help from tcech the tool is close to be fully usable from other machines and !.de network as well. Let's finish the last pieces. This looks like a very minor project but it will be great to have it finally!

Ceph crushmap visualization

a project by qakapil

The CRUSH algorithm determines how to store and retrieve data by computing data storage locations. CRUSH empowers Ceph clients to communicate with OSDs directly rather than through a centralized server or broker. With an algorithmically determined method of storing and retrieving data, Ceph avoids a single point of failure, a performance bottleneck, and a physical limit to its scalability. CRUSH requires a map of your cluster, and uses the CRUSH map to pseudo-randomly store and retrieve data in OSDs with a uniform distribution of data across the cluster. This project aims at creating graphs of the crush map, for better visualization of the Ceph cluster.
