Debian 2.2 Potato: Memorial to a Hacker
Manufacturer: Debian/GNU Linux
Price: Available from various CD-ROM vendors or free via download from the Debian web site
Reviewer: Stephanie Black
There's a lot to be said for an organization that not only depends on volunteers to develop its distribution and continually work to improve it, but acknowledges the contributions of those who participate in its growth.
In July of this year, Debian lost one of its more celebrated developers, Joel “Espy” Klecker, to Duchenne's Muscular Dystrophy. Debian, true to its philosophy, has recognized Joel's vast contributions by dedicating the Debian 2.2 release to his memory. (The written dedication can be viewed at ftp.debian.org/debian/doc/dedication-2.2.txt.)
The distribution itself is beginning to display the same kind of generosity. Debian's reputation has been further from the “novice-user” category than many distributions; this is slowly beginning to change. From installation to usage to tweaking, Debian 2.2 is a release that is fun for the techies and, well, much less of a Waterloo for novice Debian users.

There is all manner of documentation and clear instruction for obtaining the required boot, root and driver disks with which to install Debian (available at www.debian.org/releases/2.2/i386/install). There is also a caveat about expecting perfect boot disks in one go. Good floppy disks make things easier and faster.
While not all users have DSL, the network installation of Debian proves itself to be sturdy and straightforward, even when using a command-line interface. Within a half hour, the installation was complete. This is probably the most significant change in Debian: easy download and installation via FTP.
The user is offered a choice of simple or advanced installation: the former provides a quick installation of some of the more commonly used packages through a selection of application types (e.g., C++ Development, GNOME games, etc.); the latter allows the more seasoned Debian user to select individual packages. dselect (which, as of this writing, is to be usurped by a new installer in future releases) provides dependency checking and simplifies additional package retrieval and configuration.
Generally, dselect takes care of configuring most packages, allowing the user both the option of keeping the .deb packages and of setting up a running system. In an FTP download, the pertinent network configuration takes place prior to installation for obvious reasons. For some “non-free” packages, the user will be required to download additional software from sites hosting the original software first, such as the case of Real Player or IBM's JDK, and then obtain the remainder of the package via apt-get before configuration can take place. It's a bit detailed but worth it for the software. In addition, there are some packages that aren't permitted to be distributed in anything other than source packages. These require building; the process was, in the case of Pine, clearly laid out in the README. The resulting packages are then built into .deb files installable by dpkg.
I'm a bit on the lazy side and don't like wasting good prewritten code. There are some scripts included with Fetchmail that preclude much of the headaches that some associate with setting up a mail client. These scripts are found in </usr/doc/fetchmail/contrib> and prove extremely useful to those new to, or uncomfortable with, MTA's.
Debian has a long-lived reputation for stability that has made it attractive to companies like Storm, Libranet and Corel, all three of which have capitalized on Debian's lack of easy installation. It's apparent that those who are installing Potato from a CD are likely to run into problems with, among other things, disks that have errors on them. I haven't heard if this is strictly the case with official CDs; if not, Debian may want to look at putting QA restrictions on those producing unofficial versions of the installation media. The network installation has improved tremendously, however, both in speed and security of the download.
The 4.x series of XFree86 is not included in this release, but the developers are in the process of adding it to the next release, or so I've been told. This would be a marked improvement; the current version of 3.3.6x is, at best, erratic. Xservers don't work (and don't not-work) with any kind of consistency. There are still issues with GLX (and the drivers thereof) for certain cards. RIVA-based cards (G-Matrox, among others) are rumored to be wanting more of the support provided in the XFree86 4.x series. To be fair, this problem is not specific to Debian.
The selection of packages in 2.2 is rivaled only by that of SuSE Linux and predictably runs the same risks—so many choices, so many dependencies and so many package conflicts. The choice is good, but several of the packages are in need of updating. This is especially obvious in the vast numbers of libraries included, many of which are present for nothing more than backward compatibility. (Anyone willing to volunteer to fix this?) The variety in the kinds of applications included is stellar, from math and science applications to games, editors and GUIs. The “corporates” don't have much to rejoice about in Debian, but there are certainly lots of tools and toys for developers, graphic artists, academics and hobbyists.
Debian isn't intended for the absolute Linux newbie. Help is available, however, from the users, list <email@example.com>, which is quite active; most list members are willing to show new “Debs” the ropes. Be warned: traffic on this list is extensive (upwards of 500 messages daily).
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
