There is a ramdisk block device (brd), and there is a null multiqueue device (nullblk). The one can do I/O, but doesn't use multiqueue, and the other does multiqueue but cannot do I/O. So the idea is to have a new multiqueue ramdisk block device (ramblk?), which can do both. Would be most useful for testing multiqueue.

DRBD refers to block devices designed as a building block to form high availability (HA) clusters.Also possible to combine multiple devices driver for Linux(MD) and the network block device(NBD) to achieve similar functionality. DRBD is done by mirroring a whole block device via an assigned network. DRBD can be understood as network based raid-1. Only two nodes are supported in 8.4.x. For the drbd9(dev in RC phase), multiple nodes can be supported as well. Diving into it and do hacks.

dropwatch is a utility which can help you to see if data is been dropped in linux network stack. The plan is to learn what actually dropwath can do and learn how does dropwatch work? and also learn how to use dropwatch? I'd like to get it working on openSUSE 13.2.

Summary

whenenv is designed to keep the branching involved in build and functional test scripts from growing out of control. You specify a list of environment variables and whenenv will then try and reuse existing scrimps to process the request.

Using dynaname it is already possible to securely auto-update DNS records in a bind9, but this still needs a linux machine. This project is about building a CGI frontend for it that makes it a replacement for the discontinued dyndns.org service.

this work has experimented with zeromq sqlalchamy and multithreading in python to make a rich tool for syncronisation of your music collection with media devices. This project will attempt to pull all this research into a product.

Our books are also available as regular software packages such as 'sles-manuals_en'. There is a semi-private script that I use to generate the requisites (fetch the old version from the BS, tar the XML sources with daps, update .spec and .changes, etc.) and to submit the results to the BS.
