There was once a time when business moved with the pace of the locals, generally slow and steady. Today, business must keep up with the world and the fast pace of the internet. It’s a fascinating prospect and a momentous movement. But it can be very challenging and scary at times as well. More and more, it seems, success is dependent on the effective and efficient utilization of the internet. Throughout my sojourn in this digital realm, I have run across many who have an aptitude and a desire to build effective websites for profit but really don’t know the finer points of making a success out of it. So here I am going to expound and share some secrets I have learned over the ten years I have been doing this.

Ruby on Rails – Tutorial 1 – Creating a Rails Project
I heard about Rails back when I was a programmer at BlueHost / Hostmonster since they are one of the “preferred” web hosting companies for Ruby on Rails type applications. There weren’t very many clients who used it, but when questions came in about it, I always seemed to be approached with them. I guess tech support people think that if you are generally willing to help them out and you know a programming language, you know them all. Well, I eventually got sick of saying I don’t know and got some basic knowledge going of Ruby on Rails, and was pleasantly surprised!

PowerShell tutorial 5
You will undoubtedly need to use variables in your PowerShell scripts from time to time fortunately PowerShell has you covered. There are many built-in variables you can use to provide such information as the home folder ($pshome) or the current working folder ($pwd). If you would like to see a list of the built in and user defined variables available to the current session type;
Perl on Linux – Greedy Regular Expressions and the Question Marks that Tame Them
In 1986, Larry Wall invented a scripting language to solve the problems of generating reports for system administrators on unix. He called it the Practical Extraction and Reporting Language since that was its function. And it does do that. In a Unix based OS where everything is output in text, Perl has dominated somewhat because it so easy to use but mostly because of its powerful and easily used regular expression capabilities.

PowerShell tutorial part 4
Almost all of your PowerShell statements are going to include string values. Most of the time these strings are simply passed to cmdlets as arguments, but in a few cases, those strings are enclosed in either double or single quotes. The rules that govern when to use single or double quotes are referred to as quoting rules. This tutorial will attempt to explain those rules.
Perl on Linux – Formatting Text and Reports
Surely one of the most annoying things about working in a non-gui environment is convenient formatting. We have all had output that was off due to tabs or new lines or variables that overran their boundaries in the output area, etc. Provisioning for such things can be tedious, time consuming, and highly annoying. Luckily for us, perl provides a text formatting feature that is built in and fairly easy to use.

PowerShell tutorial part 3
In this tutorial we are going to focus on how to use Powershell’s operators and wildcards. We’ve learned that we can connect cmdlets together using the pipe (|) to pipeline results to the Where-Object cmdlet, which filters objects passed down that pipline. In this example;
Perl on Linux – Bitwise Manipulations
Today’s attention is directed at one of the less well known and certainly one of the least understood and used areas of perl. Although direct manipulation of bits is the only thing that a computer really does, programmatic manipulation thereof has been abstracted out for all but the tasks that can only be solved by its use. Still, there are situations and times when it becomes necessary and proper for one bit to dissolve the logical bonds which hold them to the byte and to assume, amongst the operators and variables of the language, an equal station.

Perl on Linux – Anonymous Hashes, Hash References, and Passing Them to Subroutines.
There comes a time in every perl programmers life when they have to master the hash. Anyone who has programmed in Perl for very long has run into problems such as subroutine arguments getting confusing, lagging programs due to hash tables being copied over and over, and searched for a simpler way to maintain and access data. All this and more can be achieved by the simple use of anonymous hash tables and the passing of hash table references to subroutines for processing.

PowerShell tutorial part 2.
This weeks PowerShell tutorial covers how to create pipelines and output management. Powershell pipelines are a series of cmdlets that pass objects from one to another. Each cmdlet generates an object and passes it to the next cmdlet via the pipeline. The receiving cmdlet uses that object as input and generates its own object as output. Connecting pipelines is done by using the pipe character (|).
