Is there any program/utility that will format, read the contents of and selectively back up or restore information on tapes?
that's able to selectively back up and restore information on tapes, with or without verifying. It's very easy to use as you can just tag the files or directories from menus. [See “Tar and Taper for Linux”, by Yusuf Nagree, in LJ #22—Ed] Unfortunately, it cannot format tapes, so they must be bought preformatted (or formatted under DOS). I'm not aware of any utility that lets you format tapes under Linux.

I am now trying to set up X-Windows, but I have no idea how the sections for “Device” and “Screen” of XF86Config file should be described. If you have any concrete example for my card, will you kindly let me know? My video card is: Canopus Power Window 968PCI-4M (S3)
Rather than hacking the XF86Config by hand, have you tried using xf86config? (It should be in /usr/X11/bin.) The copy of xf86config that I have here (from 3.1.2D) lists an S3-968 (generic) option and that should work for you. The xf86config that comes with the latest XFree86 might even list your card specifically. If it doesn't work, you might want to try using some of the options at http://www.xfree86.org/3.1.2/S3-1.html for other cards using the same chipset.

How do I set up Usenet news (with CNews or INN)? What documentation/books are available?
—Koen Rousseau email@example.com
First, if you want to carry the “real” Usenet, you must obtain a news feed from somewhere. Your ISP should be able to point you in the right direction, or sell you one themselves. Note that you don't necessarily need a news feed to use INN or CNews. If you only want to support some some local news groups, within a company intranet for example, then you don't need an outside feed. Looked at in that light, a Linux PC and INN can provide one of the most-touted features of a product like Lotus Notes (group conferencing and company-wide discussion forums) at a fraction of the cost. Once you've made arrangements for a feed, then you need to install the software. I recommend INN for new sites. You have a Red Hat distribution, and Red Hat has an RPM (Red Hat Packaging System) for INN on their ftp site under ftp://ftp.redhat.com/pub/contrib/RPMS/inn-1.4unoff4-2.i386.rpm. Download, then install with:
rpm -i inn-1.4unoff4-2.i386.rpm
It works right “out of the box”. You will, of course, have to configure it for your site—add your feed site to /etc/news/newsfeeds, nntpsend.ctl and hosts.nntp. Verify that the groups you want to carry are in /var/lib/news/active and newsgroups, and then configure nnrp.access to allow reading/posting from the proper IP addresses.
After that is all working add /usr/lib/news/bin/news.daily and nntpsend to /etc/crontab. News.daily and nntpsend should be run as user “news”, not as root. These programs expire old news and transmit your site's outgoing posts, respectively.
The RPM installs a FAQ under /usr/doc that should answer most of your questions.

Practical Task Scheduling Deployment
One of the best things about the UNIX environment (aside from being stable and efficient) is the vast array of software tools available to help you do your job. Traditionally, a UNIX tool does only one thing, but does that one thing very well. For example, grep is very easy to use and can search vast amounts of data quickly. The find tool can find a particular file or files based on all kinds of criteria. It's pretty easy to string these tools together to build even more powerful tools, such as a tool that finds all of the .log files in the /home directory and searches each one for a particular entry. This erector-set mentality allows UNIX system administrators to seem to always have the right tool for the job.
Cron traditionally has been considered another such a tool for job scheduling, but is it enough? This webinar considers that very question. The first part builds on a previous Geek Guide, Beyond Cron, and briefly describes how to know when it might be time to consider upgrading your job scheduling infrastructure. The second part presents an actual planning and implementation framework.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
