YAAAUU (Yet Another Article About Ubuntu Unity)
I tried. I really did. I tried to like Ubuntu’s new Unity interface and tried hard to make it work. Unity felt ok on the Acer Netbook -- the small screen is a good match for the new vertical application launcher.
It was sort of ok on the larger Dell Latitude E6500s laptop.
It was ultimately a disaster on my 64-bit desktop with the 24-inch display. Not because I had to fiddle for an hour or so to figure out how to use Compiz to give me more than the default four virtual workspaces. Not because switching between workspaces is kind of clunky, requiring either two hands to perform a triple-key shortcut followed by a mouse click to switch workspaces, or alternatively being required to navigate the fussy vertical app launcher to find the switcher app. I could have eventually accepted that. I think.
What ultimately made me go back to the Gnome 2 shell was that for the third (and last) time last week Unity crashed while I was trying to switch between workspaces. Each time the switcher application froze mid-switch and locked my desktop up *hard*. I could not even ssh into it from another machine to kill the session, I had to do a hard reset.
The crash behavior acts like a memory leak or other kind of memory error because it takes about three days of heavy use and lots of switching between workspaces before it crashes, but that last time proved to me that Unity is not yet ready for prime time, at least not for this user.
Now, running Ubuntu 11.04 under the nice, comfortable Gnome 2 interface, I only have to deal with one little annoyance: when I switch between workspaces there are frequently graphics “artifacts” left over from the workspace I just switched from. This no doubt a feature of how Ubuntu integrates the proprietary driver for my Nvidia 8200 chipset.
Life isn’t perfect, but it still beats the alternatives.
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
