I admit it. I'm hooked on Mosaic. You don't know what Mosaic is? Neither did I, until a few months ago. Mosaic is perhaps the most well-known WWW browser, at least for X and Microsoft Windows. (To find out more about WWW, see the article by Bernie Thompson in Linux Journal issue 3.)
After getting Mosaic at work (with no actual Web access, but to see how I could use it to display my own internal documentation), I decided I wanted to install it at home. I don't have Motif, which is required to compile Mosaic, but thankfully a few people have put pre-compiled binaries of different types on sunsite.unc.edu (/pub/Linux/system/Network/info-systems). Installation was easy; I just extracted the gzipped tar file, copied the binary to a suitable location, and copied the app-defaults file into a suitable location (/usr/X386/lib/X11/app-defaults). The README material from the source is also included. This is not a small package; over 1MB for the Mosaic binary on disk, and it uses nearly 2MB of RAM.
Now I can Mosaic over my PPP link from home. What fun! Interestingly, I have found that the traffic it generates is not too hard on the limited-bandwidth PPP link (except when loading large images). For the net-impaired, there is also a version of Mosaic which works over a term connection in the same directory on sunsite.
In between Mosaic-ing (OK, it does get a little boring when all you have to browse with your information browser is information you created), I had a little time to try out Frisk-0.99a, a pretty nice Risk clone by Elan Feingold (email@example.com). It is multi-player and networked, so you at least have to have loopback networking to be able to use it. Also, there is no computer opponent, although two players can share one window and one screen. It has a nice help facility, too. There is only one game style supported, but there is a lot of potential to this one.
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
