A Web-Based Lunch Ordering System
Is the on-line system better than write-order-on-scrap-paper method? Debatable, but it certainly is more fun (at least for me).
Improvements? The web page is geared towards an individual making an order, as opposed to a person ordering for multiple people. In hindsight, the web page could have been laid out with the latter in mind, and, being a superset of the former, would satisfy those requirements as well. A simple compromise could be having a multiples box, which would allow a person to order more than one serving of the same dish per order row. In the current scheme, this would still only allow four different orders per e-mail. So make it 10? 20? How long is a piece of rope? (paraphrased to make it more sinister). A design problem left to the reader.
I suppose I could also hook it into an SQL database (http://www.mysql.org/) and print out a histogram of the past orders for a particular person. A by-product of using a database is that one could print out reports, e.g., what is to be ordered for that week.
I suppose if there is enough interest and if I have enough time, I'll add a second part to this system, where the CGI script would interact with a SQL database and return HTML code to display a frequency list. And, perhaps, with some cookie interaction.
Finally, on a personal note, I've seen the future and it is Python. Look it up (and JPython too!).
Thanks to Python's simplicity, Cheng-Chai Ang (email@example.com) has blossomed from a novice Python programmer to a novice Python programmer doing useful (sometimes nontrivial) stuff almost instantly. He works for Carbonated Software Pty, Ltd. and recently started doing JSP/Java servlets after ten years of C++.
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
