Cooking with Linux - Linux, Thunderbird and the BlackBerry—a Love Story
In this article, I concentrate on BlackBerry synchronization with a Linux system, but remember that Funambol offers sync clients for many different mobile devices and smartphones. Simply point your browser to www.forge.funambol.org/download to find the right client for your mobile device. You even can sync your Android phone.
Once installed, you will see the Funambol BlackBerry sync icon in your list of applications on the BlackBerry screen (Figure 7).
Click the icon, and you should see a status screen showing Contacts, Calendar, Tasks and Notes, all with Not Synchronized below the labels. To perform a sync, you need to configure the client. Press the menu key on your BlackBerry, and select Settings (Figure 8).
When the Funambol client configuration screen appears (Figure 9), enter the URI for your machine's Funambol server. This is the same address that you entered when you configured the server. You also must enter your user name and password—that's your Linux server user name and password. A little farther down that screen, there are check boxes beside labels to Sync Contacts, Sync Calendar, Sync Tasks and Sync Notes. These are all checked by default, but you may decide you don't want to sync all those resources, so change it here if you like. You also can configure a scheduled sync and have the client update your information every 30 minutes (the default) or whatever period makes sense to you. That feature is not turned on unless you specify otherwise.
When you're done, save your settings (on my BlackBerry, I just press the trackball or the back arrow). You'll find yourself back at the status screen, and now you're ready to synchronize for the first time. Press the menu key, and select Sync All from the menu. The Funambol client will connect with your server and start transferring the information on your BlackBerry. Underneath the labels for Contacts (and Calendar and so on), the client will show how many records are being transferred. Once complete, the status screen lists the last successful sync for each resource (Figure 10).
This is all wonderful, because the Funambol server effectively is keeping an over-the-air backup of your data—handy if you ever need to reload it. But, what if you use another client on your Linux desktop for e-mail, contacts and appointments, such as Evolution or Thunderbird? Funambol provides download clients for these and others as well. Figure 11 shows a screenshot of a pretty desolate-looking address book in Thunderbird.
The plugin you need for Thunderbird is available from the Funambol community download page. Download it, and save it to a local directory. Once that's done, click Tools on the Thunderbird menu bar and select Add-ons. When the Add-ons window appears, click the Install button, and navigate to the folder where you stored the file, then click on it and install it. Once finished, Thunderbird needs to restart to load the new extension. After Thunderbird restarts, you must configure the Funambol client to connect to your server. Click Tools from the menu bar, and select Funambol plugin. When the Funambol PIM Plugin window appears, click the Options button, and you'll see a screen that, although shinier than the one on the BlackBerry, is similar as it asks for the same information, namely the server URL, user name and password (Figure 12). Enter the information, then click Close.
That's it. To synchronize Thunderbird with the contacts from my BlackBerry, all I do is click the Synchronize button and wait while my contacts are transferred (Figure 13). How long this takes depends, of course, on how much information is being synchronized and how fast your connection is.
In this way, I can keep my desktop client in sync with my BlackBerry and the server itself. As an added bonus, I get over-the-air backup with my own server without having to shell out the dollars for a BES server. Funambol, Linux and my BlackBerry—it's a match made in open-source heaven.
With the help of Funambol, a great open-source application, you (and François), can keep all that personal information in sync without having to resort to entering the information manually or paying huge sums of money for a special server running proprietary code. Well, mes amis, the time is finally upon us. That old clock on the wall says closing time has arrived yet again. François will be happy to refill your glasses a final time while we say our goodbyes to one another. Please, mes amis, raise your glasses, and let us all drink to one another's health. A votre santé! Bon appétit!
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
