Prime Time Freeware for UNIX
Editor: Richard Morin
Reviewer: Preston Brown
As I unwrapped the package which the post office had delivered, I was preparing myself for just another carbon copy of the sunsite.unc.edu archives, or perhaps some other big Unix software site. However, as I removed the book from the shipping material and observed it for the first time, I had a strong suspicion I was in for something much more professional, and thus useful, in nature.
Prime Time Freeware (PTF) has now changed the format of the book that acompanies that CDROM to the familiar glossy paperback cover and standard size that most computer books seem to come in today, so it should fit in comfortably on your shelf. The back cover claims that the collection of software is geared towards programmers and users alike. But looks aren't everything; it's what is inside that counts with a package like this.
Prime Time Freeware for Unix includes not only the book, but of course a plethora of UNIX software, comfortably housed on two ISO-9660 CD-ROMs. The “version” of the package that I reviewed was 4-2, but since it is updated every few months, a subscription buying plan is available. New issues will arrive automatically, and a one-month trial period with a money-back guarantee is standard. By the time you read this, the next issue should be out.
The CDs included are filled to the brim; PTF makes full use of the medium and doesn't skimp. Uncompressed, there is about about 5 gigabytes of information. Because the package is targeted at most Unix platforms, and is not limited to Linux, there are no binary packages; everything is distributed in source code form. This fact alone may turn off some potential buyers, but learning to compile code is an essential basic of Linux education, and should not really act as a deterrent.
The book, in addition to acting as good installation and troubleshooting guide, contains descriptions of all the packages on the disk, as well as their size and location. An index is included for easy reference. Finally, a good deal of space is devoted to describing the nature of free software itself, and it is clear that PTF is very devoted to the cause of the Free Software Foundation and independent programmers the world over.
Unfortunately, I encountered a problem early in my evaluation of the software, but one that was easily fixed. A slight flaw in the mastering process of some of the version 4-2 discs made it necessary to install a patch to the Linux kernel so that the discs could be successfully mounted. Needless to say, this was a pain, but the patch was included and was not difficult to install. PTF assured me that future issues would not have this problem.
Another drawback, while not an inherent problem, can still be slightly annoying. The PTF discs stick to the strict ISO-9660 format. This means that filenames must comply with the standard MS-DOS 11 character filenames, with no “funny” characters. PTF's decision to not use the “Rock Ridge Extensions,” which so many of us are used to, is a result of a lack of support for the extensions across all the platforms the package is targeted at.
Once the disc was mounted, I had to run a simple shell script which set up certain environment variables and the like to “customize” the disc for the operating system (in this case, of course, Linux). Navigating the discs to find software I wanted was fairly easy. Several methods are provided, including a detailed description database with paths, a more simplified database, and a HTML hypertext version of the database. A keyword index makes searching the detailed descriptions fairly easy. Information on using these databases is all well described in the accompanying book.
Just about any kind of software you are interested in is included on the discs, and it is all very up-to-date as well. For the user, there are databases (including Postgres and Onyx), archiving and compression tools, simple spreadsheets, editors and formatters (all flavors of Emacs, (La)TeX, troff), and graphics tools (data plotting/drawing, image manipulation, modelers and renderers). For the system administrator, there is plenty of communications stuff, including FAX tools, everything you could ever need for email, Usenet News, and the Athena networking suite.
Programmers will be delighted by the vast array of libraries (including graphics, GUI, etc.), and there are over 100 compilers and interpreters to choose from—some familiar, some relatively obscure. Few people have heard of CLU, but the latest version of gcc can be had here as well. There are also plenty of debuggers and profilers, syntax checkers, and the like. The full source code for X11R6 is here too. Math tools include the popular Scilab and Pari as well as many others, and for the scientist there is stuff for astronomy, chemistry, and even geology. Last, several operating systems (more or less complete) are included, like Andrew from Carnegie Mellon University, the OSF version of the Mach kernel, BSD 4.4lite, and Condor. Chances are, if you want it, it is here.
Installation of the packages is fairly primitive because of the source code format. Packages can be copied to hard drive, unarchived, and compiled by hand, or a simple included utility can be used to copy and unpack them. Either way, compiling and using them is up to you. However, these packages have all been tested and evaluated by the people at PTF, and would not be on the disc if they did not work.
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
