Linux Expo 1999
Red Hat proved once again that they can put on a good show for the Linux community. Bigger and better than ever, Linux Expo again doubled in size and attracted top speakers such as Dr. Peter Braam of Carnegie Mellon University) and Dr. Theodore Ts'o, of MIT, who now works for VA Linux Systems. Big business was there too, represented by such companies as IBM, Hewlett Packard and SGI (formerly Silicon Graphics), as well as the usual Linux vendors, such as SuSE, Caldera, VA Linux Systems, Enhanced Software Technologies, Cygnus and many others.
I talked to Dave McAllister of SGI about their involvement in Linux and Open Source and found SGI to be much more committed to this community than I would have suspected. They released their most robust and scalable file system, XFS, to the community in an effort to aid Linux in reaching what he called “Enterprise level”. This is certainly something that was applauded by everyone I talked to at the show.
One of the most exciting announcements before the show was O'Reilly's and HP's sourceXchange.com web site. I attended a discussion about this site, which is designed to aid in getting needed open source developed by obtaining sponsors who will pay developers to write the code they need and then release it to the public. This is an idea whose time has come, as another group has also started a web site for the same purpose—this one is CoSource.com from a couple of independents, Bernie Thompson and Norman Jacobowitz, who write for LJ. It's obvious that Bernie, Norman and O'Reilly are committed to the community and wish to drive open source development, but I was a bit suspicious of HP. When I asked about HP's motives for involvement in this project, Wayne Caccamo told me HP felt this project was inevitable and wanted to take a leadership role and they wanted to “ingratiate” themselves to the Open Source community—talk about honesty! After that remark, I was ready to believe anything. I'm looking forward to seeing how both these sites work out. (For more on this subject, see Bernie Thompson's article in this issue, “Market Making in the Bazaar”.)
There were the usual fun things to do, such as a chili pepper sauce contest and a paintball contest pitting vi against Emacs once more. Once again vi won, proving it is the best editor available or that its advocates are the best shots. More than one group bought blocks of tickets to a local showing of Star Wars—The Phantom Menace. The ALS (Atlanta Linux Showcase) group invited me to go along with them. Fun movie.
I especially enjoyed my booth time talking to current and future readers and authors. In particular, it was a pleasure to finally meet Alan Cox and Telsa Gwynne.
Alpha Processor, Inc., a Samsung company, announced they were joining Linux International; Richard Payne and Guy Ludden presented a check to Jon “maddog” Hall. I got the picture and then took several others of Jon, including one with a people-size Tux, who was roaming the show floor.
Compared to LinuxWorld, Linux Expo came across as more polished, more “we've done this before successfully”. LinuxWorld had a lot of glitz—electricity and energy filling the air—that just wasn't there at Linux Expo. I think this mostly had to do with the fact that it wasn't the first time for these guys—the experience showed. The speakers all like Linux Expo better, as the Expo paid their travel expenses while LinuxWorld left them to get there on their own. LinuxWorld had more people and more vendors, but they also have the advantage of being in Silicon Valley.
Evan Leibowitz described the Expo as “the show where Linux lost its innocence” due to two unpleasant situations that arose. One was Pacific HiTech's being kicked out for passing out t-shirts without buying booth space. The other was the use of the Red Hat trademark without permission, by LinuxCare on their poster parodying a Palm Pilot ad. No matter which side you took on these incidents—the calling of lawyers certainly signals the “end of innocence”.
The show was definitely a success. I talked to Bob Young on the last day, and he certainly seemed pleased with how it had turned out. See my interview with Bob in this issue. For vendor announcements, see “UpFront”.
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
