A Programmer’s Discussion: Procedural vs. OO
So I have been writing code of one sort or another for over 15 years (mostly Perl) and there is still one thing I don’t get ... what is the advantage of object oriented programming (OOP) over procedural programming (PP)?
I want to have an open discussion on the topic. Obviously I deal with both OOP and PP, but I am strongly in the PP camp. I am wondering “did I miss the boat”? I heard that Perl 6 will have very strong OOP and possibly will be pure OOP only, so if Larry Wall (way smarter then me) thinks it is a good idea, I must have missed something.
Here is my simplified position, I find OOP harder to read, harder to maintain, and harder to use. PP seems so intuitive and straight forward. I find most PP code I can read and understand with very little in the way of comments or documentation, the code is the code you can see what it is doing (it is mostly self documenting). In OOP I find that I am constantly trying to figure out what it is doing, it seems more... nebulous. I normally have to jump around more; it is not like PP where you are mostly reading top down.
Tell me what you think and help me expand my knowledge. I am not trying to promote or bash either method, I am trying to learn, and I hope all of you will respond in the same spirit. When you respond please let us know what camp are you in.
Some possible talking points for the subject:
What can OOP do that PP can’t? or What can PP do that OPP can’t?
What advantages does OOP have over PP? or visa versa?
Performance benefits of OPP/PP?
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
