An Ideal Appliance?
The ugly truth of the matter is that the AR Infotek Teak 3018 doesn't know very well what it's trying to be. The marketing literature makes it look like it's designed to compete with the sort of firewall/switch appliances that you get at your local computer shop, when in fact it's an OEM device that is incomplete without a lot of tinkering. Presumably, it was designed to sell in large quantities to OEMs and VARs who will then install the appropriate add-ons to make it sing right out of the retail packaging, but if this is the case, the folks over at AR Infotek need to do a lot more work on improving their documentation and organizing it in a way that's intelligible. It also could use some basic niceties like a packing list, a price guide, environmental specs and a readable block diagram.
On the other hand, it's a hardware platform that's well suited to hackers—particularly hackers willing to do their own legwork and not rely on their hardware vendor to tell them what it is they're actually buying. The possibility of teasing audio and video capture functionality out of a network appliance is interesting as well, raising the prospect of constructing low-end PVR for capturing content destined for one's iPod rather than one's TV. The careful selection of Linux-friendly hardware throughout and the inclusion of driver sources on the CD is another point in its favor for the hobbyist. We'd give it a B+ as an OEM product for network security, mostly for its inadequate documentation.

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
