Converting Office Documents
Now and then, office-type documents need to be converted. The latex users have always been able to produce a variety of formats from the command line, but for the OpenOffice/LibreOffice users, manual labor has been the solution. That changes with unoconv. Now you can convert to most file formats directly from the command line.
Unoconv is handy for many tasks. I commonly use it to convert all documents in a directory to PDFs, or MS Office compatible formats for clients. The beauty of it is that these previously tedious tasks are now one-liners.
If you're on ubuntu or derivates (I'm on kubuntu) you can install unoconv from the command prompt:
$ sudo apt-get install unoconv
Having done that, you need to start the server half of unoconv.
$ unoconv --listener
Give this a few seconds to settle. It starts an instance of OpenOffice in the background which it ties into. To use this instance of OpenOffice for format conversion, now try the following:
$ unoconv -f pdf *.odp *.odt
This will convert all text documents and presentations to pdfs. There isn't much control in the process, but if you want the standard output, it is a great help.
When it comes to exporting to MS Office formats, you have slightly more control. You can, for instance, target the format doc, doc6 and doc95, meaning Word 97/2000/XP, Word 6.0 and Word 95 respectively.
The project is alive, so there is good hope to have the final glitches sorted out. The tool spits out a couple of scary warnings now and then, but the documents seem to turn out well.
The conversion is based entirely on OpenOffice's conversion, so the quality is what you know from there. Since the conversion is automatic, you might have to limit yourself at times. For instance, I've learned that not using the arrow connectors, but instead relying on lines, helps in odp to ppt conversion. Also, the ppts produced are not compatible with the very latest MS Office on Mac - but then you can create pdfs just as easy.

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
