The Software World—It's a-Changin'
Welcome to my attempt to write a “Stop the Presses” with a subject that really asks to be editorialized on. First, let me set the scene: today is January 22. The important events of this day are:
Bill Clinton is once again accused of a sexual impropriety.
The Pope is in Cuba.
Netscape has announced that their browser is now free and that they will freely distribute the source code for it.
Microsoft has somewhat folded in its browser battle with the U.S. Justice Department.
The first two items are just for context—it has been an exciting day. I am really here to discuss the last two items.
Let's get the Microsoft information out of the way first. My understanding is that a compromise has been reached between Microsoft and the justice department—the Internet Explorer icon will not appear on the desktop, but the browser itself will still be included. As the easiest way to get a new browser is to download it off the Internet and 90% of all personal computers today come with Microsoft Windows, it seems that all we have done is made it a little harder for Internet Explorer to be on 90% of the desktops. Hopefully, there will be further developments in the Microsoft vs. the U.S. Justice Department game.
The Netscape item has two parts. The first, making the browser available for free really is a necessity; 90% of new personal computers come with Windows and, thus, Internet Explorer. Whether IE is better than anything Netscape offers or not isn't the issue if one comes with your computer and you have to go buy and install the other one. Numbers back up this statement. Netscape used to account for about 90% of the browser market while 60% is probably the case today.
The good news for Netscape is that they have managed to shift their revenue stream away from stand-alone client software. Their own numbers show that in the fourth quarter of 1997 these revenues were only 13% of the total, down from 45% a year earlier.
By far the most interesting part of Netscape's announcement for the Linux community is the fact they will release the source code for Communicator starting with 5.0. Sure, this will also make a change for them in the Windows arena and may force Microsoft to make some brave decision as well, but let's look at what this does for the Linux community.
The first thing I see is talk on the Gnome mailing list about a version of Navigator using Gnome. Call it Gnomescape, it is potentially a full-featured browser with a look and feel that is likely to become the Linux standard. [For more on Gnome see the “KDE and Gnome” article by Larry Ayers in issue 24 of Linux Gazette, January 1998.]
Netscape claims they are releasing the code to allow the Internet community to contribute to the development. (I expect Linux helped them realize that is possible.) For us, this can mean that instead of complaining about Netscape bugs, we can fix them. I expect, based on Linux history, the best, most bug-free version of Netscape will appear on Linux systems first.
Free Communicator and free source code mean that Linux systems become a much cheaper choice for “Web Appliances”. It also means inexpensive kiosks at shopping malls, car dealers, etc. While I am sure Netscape made this decision to help their competitive position with Microsoft, I think we will see a huge impact on the Linux scene. Of course, if Linux replaces Windows as the operating system installed on 90% of the PCs sold today, Netscape will be as happy as the Linux community.
What's still up in the air is what sort of license the source code will fall under. GPL is one choice; a license more like that of BSD is another.

Practical Task Scheduling Deployment
July 20, 2016 12:00 pm CDT
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
