In my last post I had posted a link to a *.tar.gz file containing the source code to both a very generic Linux RAM disk module that I wrote for the Linux 2.6.26.x kernel (was tested on Fedora 8 and Debian 5.0.1) and the source to a single purpose user binary that obtains the total device block count (no. of sectors) via an ioctl() and also performs some write(), lseek() and read() operations.This way, if the user were to monitor the /var/log/messages file they would see exactly where the process is in the driver code (I had placed many printk() messages for learning and tracking purposes).
I had made some updates to the device driver. The updates are so minor that the revision level of the driver incremented from 0.1 to 0.1.1. The updates are as follows:

On my primary blog I have just finished posting an entry on my latest article to be published in the 4/2009 issue of Linux+ Magazine, The Linux RAM Disk. My last article written for the same periodical has just hit the news stands earlier this month (issue 3/2009, Linux Storage Management).

As I wait for the next release of Fedora in 6 days, recently I have been spending some time away from GNU/Linux and playing with OpenSolaris UNIX. And might I add that it is a very impressive distribution. From the implementation of ZFS (and the Time Slider feature in GNOME) to Dtrace along with some other nice features.
I have worked with Solaris for many years and while Sun has always been ahead of its time with features and functionality, they always lacked in usability over the GUI. Usability over the CLI was always great and always there, it is just the GUI never looked good as it traditionally defaulted to CDE until recently (GNOME).
