August Meeting Report

More than twentyfive members were on hand for the Linux presentation. After announcements and discussions about future programs, our president, Jack McKinney introduced members of the Central Texas Linux Users Group [CTLUG] for a mutli-part presentation.

Scott Boland brought an intel box loaded with a recent Red Hat distribution. We were able to see the screen thanks to the overhead projector as he demonstrated the various uses of lilo, the mutliple partition/disk loader distributed with Linux. He reconfigured it a few different ways, though he was not willing to set it up to boot of the non-existent network.

Lindsey Haisley then demonstated how [and why] to build new kernels. He used menuconfig, but talked about Xconfig and makeconfig as well. Lindsey pointed out the uses of loadable module support. There's a daemon that listens for requests for modules that aren't actually part of the kernel, but can be loaded as required. This is a lot like System V Release 4 loadable modules. It keeps the kernel lean so that you can fit more onto a boot disk, and not waste memory when the support is not needed.

Jack McKinney demonstrated some neat tricks, such as "cat interrupts", which shows you which interrupts are in use. You can also cat ioports. He then explained some of the features of /proc/sys/kernel that are useful for tuning the kernel. You can change file-max or inode-max on the fly!

Finally, Lindsay brought up a wierd X11 window manager that looks like Windows '95. No word yet on the look and feel litagation sure to follow.

Thanks to Scott Boland and Lindsay Haisley for the best Linux presentation to date.
