Installing and Getting Started with HerculesCore

HerculesCore is a framework I developed that originally started when I worked for Core Logic Systems (no longer in business). My boss there had developed what he called core, and he had been planning to release it open source, when the company went out of business I started changing core into what it is today, a fairly straightforward, easy-to-use framework that allows web developers, experienced and inexperienced alike to program faster and more efficiently. There is very little of the original framework left other than the “using” function, but we’ll get to that later.

First thing you need to do is download HerculesCore. Next unzip it and place core in the folder you are going to use it in.

I know there are a few people out there that would like to get the most out of their MS Excel without a lot of work.  One of the features that I have found easy to use and very helpful in performing data analysis and displaying it in a non-cluttered manor is to insert a PIVOT TABLE. A PIVOT TABLE is a data summarization tool….it allows you to reorganize and display data in different ways.

Creating a Pivot Table is a very easy process and depending on what version of Microsoft Office you have the menu options may be different but the overall process is the same. For the purpose of this instruction I am using Microsoft Office 2010.

Step 1 Be sure that your data is in Excel and has Column Headings (e.g. NAME, PRODUCT, DATE…ect)

Step 2 Open the workbook where your data is stored.

Step 3 Select a cell in the current sheet (but off to the side of your data) or in another sheet of the same workbook (this is where your PIVOT table will be displayed. I suggest the PIVOT TABLE be displayed in a separate sheet)

Step 4 Once you have decided which Sheet and Cell to display your data in, left click in the cell (If this sheet contains other data be sure you leave at least two rows empty above and as many rows below as you think you will need…because the table may override this information if it needs to expand to display the amount of data selected)

Alright, so today we are going to compare two sets of code that do the exact same thing: generate prime numbers! Exciting, right? I use this example because my boss at one of the first software development companies I worked for gave me a challenge, to create a prime number generator in seven lines of code or less. I did so, and now its down to one line (kind of), but is it really the most efficient code? Not at all, but it does its job.

I also created another version of the code that runs much more efficiently, but it is significantly longer. Let's begin.

I want to start by showing you the one-line code and explaining it. Here's that code:

This one generates all prime numbers between 0 and 10000.

<?for($i=2;$i<10000;$i++){for($x=2;$i%$x!=0;$x++){echo$x==($i-1) ? $i." ":"";}}?>
