Each year, the USENIX organization (http://www.usenix.org/) puts on a technical conference dealing with UNIX and other UNIX-like systems. This year they had an emphasis on free or Open Source operating systems, primarily Linux and *BSD. The conference was held in New Orleans, Louisiana from June 15th to the 20th.
Many day-long tutorials were offered on Monday and Tuesday including “Inside the Linux Kernel” by Stephen Tweedie, one of the EXT2 developers, and several talks on Networking and Security. I attended “Hot Topics in System Administration”, given by Treni Hein and Evi Nemeth. They covered many topics including Samba, Packet Filtering and IPv6.
I found it refreshing to see a vendor exposition (albeit a small one) comprised completely of UNIX-friendly companies. O'Reilly was there, displaying all of their titles for sale at 20% off. Needless to say, this made it one of the most popular booths. Most of the faces were familiar: Red Hat, Linux International, InfoMagic, the three heads of BSD and others. Among the unexpected participants was the FBI, just a short distance from the Free Software Foundation. The whole atmosphere of the exposition was quite relaxed, without the hectic feel of COMDEX and other large industry trade shows.
Each evening offered several talks by different people on a wide range of subjects. I caught “The State of Linux” talk by Linus Torvalds on Thursday afternoon. He set Aug/Sep 98 as a hopeful release date for the 2.2 kernel. Another event that took place every evening was the “Birds of a Feather” (BOF) meetings, which were designed as a place for people with common interests to come together and discuss their ideas and goals. It was also a great place to rub shoulders with some of the “big names” in the UNIX community, such as Keith Bolstic, Eric Allman and Jon “maddog” Hall.
What UNIX conference would be complete without a terminal room? Luckily, Earthlink and openBSD donated machines and bandwidth and created a room with thirty or so machines running openBSD, connected to a T1.
If I were to do it all over again (and I most definitely want to), I would spend more time planning what I want to learn. I was a bit overwhelmed by the sheer number of talks/events, and therefore found it difficult to focus on exactly what I wanted to get from the experience—I was constantly spreading myself too thin. For any UNIX, Linux, BSD etc. lover, USENIX is a must at least once in a lifetime. It is a very friendly and co-operative environment and has definitely earned its reputation as one of the hubs of the computing community.
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
