Xess Spreadsheet for Linux, Standard Edition
Welcome to yet another review of an application for Linux. Wait! This cannot be, for Linux has no applications! This is well-known, a fact we've heard since the days of “Windows is the future, get used to it!” and is probably the reason Linux has no user base and has failed miserably in the server market and the stock market. Hence, one must conclude that this spreadsheet is in actuality a spectre, and although you think it's real, it is a fantasy, as are the millions of Linux users you thought existed and the newbie Linux gazillionaires.
The subject for today is the Xess Spreadsheet for Linux, Standard Edition. We must specify Standard Edition, because there is also a professional edition which handles very large projects. However, the standard edition deals with up to 1024 columns and 99,999 rows per sheet, with 512 sheets per workbook, which should be more than enough for your next stat class assignment. Xess has been good about supporting several distributions of Linux, so you can almost certainly run it regardless of what distribution you have (which is, if I may opine, the way things ought to be). What is so special about this spreadsheet, and why might you prefer it to the StarOffice or Applixware spreadsheets?
To be honest, my very first impression was “Ack! What a stupid license!” You know the kind, those last-minute “installing this software indicates agreement” licenses full of the weirdest, off-the-wall restrictions, including a ban on un-assembling (do they mean disassembling?), de-compiling (if you figure out how to do this, let me know) and reverse engineering. Forbidding these things is rather absurd, and the legal reasoning behind these last-minute licenses is about as meaningful as the reasoning of little kids who always say, “I called it!”
Disassembly of a program (though not necessarily of a spreadsheet) is a superb way to begin learning assembly code, while reverse engineering had a very large hand in promoting the PC phenomenon (imagine if no one had reverse engineered the first IBM PC to enable cloning). De-compiling would be so clever and an excellent way of open sourcing binaries, but as far as I know, it hardly works. So why forbid these things, since they're no threat at all and the last-minute license probably isn't legally binding? Just in case. Gotta call it. The other problem is the bit about reserving the right to revoke the license, which is irritating. I'd certainly not depend on a product if someone had the right to revoke it whenever, but apparently that's how commercial software is. CD manufacturers don't bother with this licensing nonsense, and it hasn't hurt them any. At least the license is short, as is the small-footprint installation of the spreadsheet.
My second impression was “Geez, I wish we had this in college.” Instead, we had silly Windows boxes, with “blinky the dancing paper clip” et al. UNIX has such an academic history, I don't understand why it isn't the de facto standard in universities, but for some reason it isn't, although recent student protests may chase Windows out of colleges. Now that we have Linux, a free and superior OS, there's no excuse to keep running Windows in the schools (besides, a free-source OS is politically very correct). And, what with high-quality applications like Xess (or, for example, Word Perfect and the office suites), there's even less of an excuse.
Even though it comes from the commercial sphere, Xess is one more brick in a solid foundation of Linux applications. A free OS running a high-quality commercial application is, after all, preferable to a buggy, proprietary OS running a bloated proprietary application (with embedded flight simulator). What you may infer from the preceding sentence is that Xess is a high-quality spreadsheet, so operating from this assumption, let's have a look-see.
It's honestly a bit dull to list everything a package can do, and it risks sounding more like an advertisement than any sort of review. Still, if you're thinking of using a spreadsheet, you probably want to know what it's capable of doing. There isn't room to list everything, so I recommend going to www.ais.com/Xess/xess4_features.html for the complete list. I'll try to cover the major points here.
Xess looks like any other spreadsheet (Excel, Lotus, StarCalc, Applixware Spreadsheets, etc.), so its interface is obvious and intuitive. Xess has all the functions one expects of a spreadsheet, including some outstanding ones. At the basic level, Xess has the standard functions complete with conditional and Boolean operators, iterative and double-precision calculation, inter-sheet cell linking and formula constraint checking. The mathematical functions include the standards found on a good pocket calculator, such as exponents, logs, trig, matrices, as well as sigmoid, gamma and log gamma functions. The matrix operations in particular are extensive, even including Fourier transforms, correlation matrices, curve fitting and linear equation solving. Financial functions include the usual exciting things like rates of return, present and future values, interest rates, yields and all that. Statistical functions are thorough, and on the whole, there is more offered than I remember finding in StarOffice or Applixware.
Maybe it's funny that Xess is distributed by a company called Business Logic Corporation, because Xess, while wholly adequate in the financial department, is rather well-suited to scientific, statistical and mathematical operations. In any event, the test of whether a spreadsheet could be useful to me is if it can be my pocket calculator. Xess comes closer to substituting for my pocket calculator than other Linux spreadsheets, and even has some stat and matrix functions my calculator doesn't have.
Xess is largely a calculation-oriented spreadsheet. The calculation engine must be praised, because it's actually fast, although the graphing capabilities are less extensive. The graphics basics are covered, and you can make the standard scatter, line, area, bar, stacked bar, histogram, pie, surface, contour, polar, hi-lo, control and box graphs, and there is much technical flexibility. Still, there isn't much aesthetic control beyond standard representation, which is fine. As for calculation, there are more functions than I can count, nearly 250, all of which are nicely referenced in the manual. I would be more than surprised if someone found the calculation capabilities inadequate.

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
