Will I be ditching other e-mail clients and switching over to using Zimbra Desktop full-time? In a word, no. Zimbra Desktop is a very nice e-mail client. It has the features I expect a modern client to have, it can handle multiple accounts easily, and everything is rolled up into a nice easy-to-install package. But being “just as good” as other e-mail clients is not enough to make me switch. Even the coolness of Zimlets is not enough.
The integration of Zimbra Desktop with the Zimbra Collaboration Suite is, naturally, very good, and if I were using ZCS as my primary mail server, the choice to use Zimbra Desktop would be obvious. I would. And, that is, I suppose, my final recommendation. If you are using ZCS, Zimbra Desktop lets you access your messages, contacts and calendars even when you're off-line (that's the promise, anyway), and you can use it for all of your other e-mail accounts too.
Zimbra Collaboration Suite
The documentation for Zimbra Desktop states that you have to have a Zimbra Collaboration Suite (ZCS) to connect to. This is not technically true, as you can use Zimbra Desktop with Gmail, Yahoo mail or any POP or IMAP server without a ZCS in sight. However, the integration with Zimbra server is, naturally, very strong, so if you run your own e-mail server, the ZCS + Zimbra Desktop combination is very compelling.
One of the main benefits of running ZCS as your e-mail server is that the installation is easy when you compare it to setting up your typical SMTP + IMAP + ClamAV + LDAP server installation.
ZCS comes in both a commercial Network edition and an open-source Community edition. Both have excellent documentation, which is great help in getting it up and running.
Even if you do not use ZCS, you still might want to give it a try. The download and install process is easy, and you'll be up and running quickly. I think you'll find, as I did, that alternatives, such as Evolution, Thunderbird or Gmail work equally as well, and that there is no compelling reason to move away from what you are already using—in which case, there is a nice uninstaller.
But, then again, maybe you'll love it and never want to use a traditional e-mail client again.

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
