Stumbled across this, got a good laugh - Thought I'd share

In my last post, I stated that if you had a IT related question, feel free to email it to me at paulwelchonit@yahoo.com and I would do my best to answer your questions about Programming, Databases, etc.

 However, if you email me something that can be solved by a 2 second google search, I found this website for all those people who find it more convenient to bother you with their question rather than google it for themselves. Its called Let me google that for you, and simulates a google search for the recipient.

I recieved a question from a reader asking me how to setup e-mail for outlook express on his blackberry. So, I used the website a and sent him back this : 


(check it out, haha.)

The website, if you wanna give it a shot, is here : http://lmgtfy.com/

RapidMiner : A how-to guide

In my business intelligence class we have been using a program called RapidMiner, which is an open-source system for data mining. In this class, we are analyzing almost 23 gigs of raw data, and it can seem very confusing at first. Unless you are running a very powerful computer, Rapid Miner can often freeze and crash due to the large amount of data and processing usage.


In this post, I will detail how to make RapidMiner work with your computer to its full potential, as well as detail how to use Rapid Miner.




Speeding Rapid Miner up:


1) Close all process you DONT need with task manager. Use common sense with this. Keep core processes and programs running but end everything unnecessary. (Example: Close things like limewire.exe or itunes.exe, but keep things like windows.exe and rapid-i.exe open!)


2) Find out how much RAM your system has. You can accomplish this by right clicking "My Computer" and clicking properties.


3) Go into your C: drive and then the program files folder. After that, find Rapid-I folder and open it up. Then,
a) for windows open up the rapidminerGUI
b) for Mac or linux, the other ones.


It should bring up a script in notepad.


Go down to where you see the line about JAVA MEMORY Max. Change it to something compatible for the amount of RAM your system has (remember to leave 1.5 - 2gb of ram for your OS.) For example, if you have a 2gb laptop, changing the amount to 1024 should be fine, although not preferable. It is a very powerful program and needs adequate resources to run.


This should get your RapidMiner working at full power.




Using RapidMiner:


Following are some video tutorials on how to use Rapid Miner. Good luck!

Information Systems: No longer a cost center, but a essential tool for profit maximization.

After a thorough look through many different business IT cases over a two decade period, there is one thing I am sure of - The effective utilization of Information Technology can provide a HUGE competitive advantage.  Companies who neglect their IT resources/department , or treat it as a necessity rather than an asset will fall wayside to their competitors.

I recently got through reading about Harrah's, the nationwide chain of casinos, and how they utilized business intelligence and Information Tech to become a powerful force in their market and realize huge gains. I recommend my readers check this article out, here are a few excerpts:

"To compete on analytics, organizations also need to compete on technology, and that means constantly monitoring cutting-edge IT developments. The key prerequisite is a data-oriented strategy that allows a business to rapidly pull information from every plausible source. These technologies could include enterprise resource planning, CRM, point-of-sale and other transaction technologies. Competing on that information, then, necessitates using an enterprise data warehouse that can store, integrate and present the data in formats that can be easily accessed and analyzed."

"New technologies and data sources that were once just brainstorming ideas are now becoming a reality, much to the advantage of analytical competitors. For example, information content in data warehouses has long been dominated by structured data. But significant progress is being made toward incorporating equal amounts of unstructured data, which includes natural-language data sources such as word processing files, e-mails, text fields from databases and applications, and even voice recognition."
