Project Plymouth

The aim of the Plymouth project is to answer the oft-stated user requirement that their computer startup be flicker-free, seamless, shiny and logged. In this post I examine the current state of the project and show you how to customize your startup and shutdown experience.

Fedora 11 New Extended File Attributes Namespace

I am experimenting with XAM (eXtensible Access Method), which is a storage standard developed by SNIA (Storage Networking Industry Association and have developed a first prototype of a VIM (Vendor Interface Module) for the ext4 file system based on adding another namespace to the current extended file attributes support.  Since other Linux developers might be interested in how to add an extended attributes namespace to a file system, I decided to publish this post as a guide. Extended file attributes (EA) are extensions to the normal attributes which are associated with inodes in a file system.  They are simply name:value

Fedora 11 nVidia Twinview Support

Fedora 11 (Leonidas) ships with the nouveau nVidia graphics driver preloaded by default if a nVidia graphics card is detected at install time.  Previous versions of Fedora used the older X.Org nv driver. The nouveau project aims at producing Open Source 3D drivers for nVidia graphics cards.  According to the nouveau project Wiki 2D-support is in fairly good shape with EXA acceleration, Xv and Randr12 (think of dual-head, rotations, etc.). Randr12 should work for all cards up to, and including, Geforce 9000 series, although some issues with Geforce 8/9 laptops may still exist, for such issues bug reports should be

Linux Security Capabilities

In earlier times, the standard security model for GNU/Linux and Unix operating systems gave general users a minimal set of privileges, while granting full privileges to a single user account, i.e. root, that was used to administer the system and users, install software, mount and unmount filesystems, loading kernel modules, bind a process to a privileged port and run many services. This dependence upon the root account to perform all actions requiring privilege was recognized to be somewhat dangerous in that it was all or nothing and not suited to compartmentalization of roles.  Furthermore, it increased the risk of vulnerabilities
