ZOTAC ZBOX HD-ID11
For years I have toyed with the idea of setting up a media server for my entertainment center. The challenges in my way included cost, features, aesthetics, background noise and user-friendliness. All of those things are important because I'm not the only person who will be using the system I build. Hardware and software technologies are coming together to address all these challenges. With the advent of the Intel Atom processor and the NVIDIA ION GPU, affordable hardware now is available that allows for an HDTV media server. Likewise, software, such as XBMC and Boxee, has matured and provides a fun and friendly user experience for all levels of users.
For $249.99, the HD-ID11 is small, quiet and looks slick. The chassis is all plastic and feels a bit flimsy when deconstructed. However, the plastic is fairly thick and has tight tolerances. When the cover is in place and set screws tightened, it feels solid.
The front of the HD-ID11 has a 3.5mm headphone jack, a 3.5mm microphone jack, a USB port, an SD card reader, a power button and activity LEDs. The top of the case has a large blue O that lights up while the machine is on. It looks nice, but it can be turned off in the BIOS if it is bothersome. On the side, there is a USB port with a rubber stopper, and on the back, there are four more USB ports. The back also sports HDMI and DVI outputs, 10/100/1000 Ethernet, eSATA, optical out and a port for the power brick.
What makes the ZOTAC ZBOX HD-ID11 special is all the power that's packed into the small package. The machine is only 7.4" x 7.4" x 1.73" (188mm x 188mm x 44mm). Here are some of the main technical specs:
CPU: Intel ATOM D510 (dual-core, 1.66GHz), 667MHz front-side bus.
Chipset: Intel NM10 Express chipset.
GPU: NVIDIA ION GPU (with 512MB DDR3 memory).
Networking: Gigabit (10/1000/10000 Mbps), 802.11b/g/n.
Audio: onboard 8-channel digital audio, stereo analog audio.
I/O: HDMI, DVI (DVI-to-VGA dongle included), S/PDIF, mic/headphone, 6 x USB 2.0, RJ45, eSata.
Memory slot: 1 x 200-pin DDR2-800 SO-DIMM slot.
Hard drive slot: 1 x 2.5" hard drive (SATA 3.0Gb/s).
One thing separating the ZBOX from the competition is that it does not ship with memory or a hard drive. This allows you to tailor the computer to your needs without buying too much hardware or paying an inflated price for those components.
The HD-ID11 has support for up to 4GB of memory by using a single 200-pin DDR2-800 memory module. I installed 2GB of Kingston DDR2 RAM, which performed flawlessly. If you plan on using the ZBOX for playback only, 1GB of RAM should be sufficient. With the extra RAM available, I decided to use a 640GB hard drive and went with local management for the media. The Intel Atom processor is powerful enough to do a good job with video playback (via the NVIDIA ION GPU) and manage the library at the same time.
The ZBOX uses a standard American Megatrends BIOS that can be entered by pressing the Delete key during the boot phase. The settings I felt worth changing included the boot priority, turning off the ZBOX logo at boot time and having the ZBOX restart after a power failure. The other BIOS settings had sane defaults.
The first thing I noticed when I booted the ZBOX with Ubuntu was it did not take long before the CPU fan would spin up to maximum and start to sound like a jet engine. This was worrisome, as I intended to keep the ZBOX in my living room. Fortunately, there is a BIOS update available to fix this problem. As with most BIOS updaters, the updater used by the ZBOX requires a DOS boot disk to run. See wiki.fdos.org/Installation/BootDiskCreateUSB for some easy-to-follow instructions for creating a free DOS USB boot drive. Once the free DOS image is booted, you can switch to the drive with your BIOS flasher and follow the updater instructions.
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
