The Linux Sampler

Reviewer: Harvey Friedman
The Linux Sampler? “What can that be all about?” I asked. After reviewing a copy, I can say that SSC has produced a useful “Linux Resource Guide” of “Resources, Technical Information, and Articles from Linux Journal”, with an emphasis (as we might expect) on Linux Journal articles.
To help demonstrate the organization of the book, I will list the table of contents:
An Introduction to Linux
Linux in the Real World
Talking about Linux
Politics, Opinions and Future of Linux
Linux and Other Operating Systems
Also included are a Glossary and an Appendices. Each of these seven main sections has anywhere from three to six articles, selected mostly from LJ. A nice feature of this organization is that one doesn't have to leaf through seven or eight issues of LJ to read about one of the topics above. For example, two interviews with Linus Torvalds that were published in issue 1 and issue 9 are placed back to back in chapter 3 and Chet Ramey's bash articles from issues 3 & 4 are a single seamless article in chapter 6.
Chapter 1 is comprised of two parts. The first three articles discuss the history—albeit in a broad overview—of Linux and will probably be used as background for many other publications. The next three articles are more of the what-is-available-for-me-now type and will be dated in a few years (I hope not sooner than that).
Chapter 2 has brief case studies of how Linux systems either replaced older mini-computers and improved upon their functionality and—user satisfaction—or how Linux systems solved new problems. These are well-written and should prove useful if one is trying to get a supervisor to authorize using Linux at work.
Chapter 3 has interviews with Linus Torvalds, Slackware's Pat Volkerding, and DOSEmu team leader James MacLean. I enjoyed the interviews, but I already enjoyed them in the various issues of LJ as well.
Chapter 4 seemed lacking to me. Although each of these articles was interesting in LJ, I feel that they lose something when brought together. Perhaps because the content of each article stimulates thinking, dreaming and imagining about the future, the effect is lost when they are read sequentially. I suggest reading them at least a sleep apart.
Chapter 5 is another useful one. An article comparing memory and disk requirements for Linux, Windows NT, and OS/2 appears to be a thorough evaluation. The remaining articles discuss emulators to run other code on Linux—iBCS2, which runs binaries for other Intel-based Unices; mtools, not really an emulator, but a set of tools for accessing MS-DOS file systems (particularly on floppy disk) from Linux; Wine, an MS-Windows emulator that is still in test mode; and SAMBA, an implementation for Linux of the SMB protocol (used by LanManager, Windows for Workgroups, Windows NT, and OS/2). SAMBA was the only one of these that I had not heard of before I read about it in LJ.
Chapter 6 contains articles on porting other Unix applications to Linux, the GNU C Library, and bash. These are all pithy but meaty articles, yet I do not like this section being called “Technical Articles”. Perhaps something like “Tips for Programmers” would have been a better title.
Chapter 7 barely scratches the surface of system administration, but what is there is well-written.
The Glossary is generally good, but I have a few quibbles: e.g.: “Cisco A brand of router”.
In the Appendix are found “Linux Products and Services Directory”, “Linux User Groups”, and “Linux Resources”. These are fine now, but some of the references have to be updated already. For example, in the list of Usenet usegroups, page 211 doesn't reflect the most recent division of the comp.os.linux newsgroups. Therefore, the newsgroup comp.os.linux.setup, one invaluable for those new to Linux and Unix, is not included.
Overall, this is a worthwhile book, even for those who have been subscribing to LJ since Issue 1. The collection of related topics, the good glossary, and the list of newsgroups, ftp sites, products and services, all together in one volume, make it a source that you want next to the Network Administrator's Guide, Linux Installation & Getting Started, and the HOWTOs. This reference (which could also be named The Linux Journal Sampler) does nothing to tarnish SSC's reputation.
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
