Like a lot of web developers, I'm not always that disciplined when it comes to the file naming convention I use and I sometimes end up with a situation whereby I have some files that are in lowercase, some that begin with a capital, and some that are a bit of a mixture.

One web site I maintain contains about 2000 web pages and has about 20,000 hyperlinks. As you can imagine, I had one of those sinking feelings when I was told that in order to migrate the web site to a new content management system, all the file names and hyperlinks would need to be changed to lowercase.

Whenever I am presented with a problem like this, my instinct is always to write a Perl script using one or more regular expressions to solve the problem. This particular situation was no exception.

Change a string to lowercase

The following regular expression changes all the characters in a string to lowercase. The first part of the regular expression finds a hyperlink, and the second part converts the string. (Just in case this article is not displayed correctly, there should be a single backslash in front of the 'L$1').

Change a filename to lowercase

Likewise, changing a filename itself is very simple. The following two lines perform the task quite nicely:

(Again, there should be a single backslash in front of the 'L$name'.)

If you need more information on how to incorporate the above code snippets into a complete script, feel free to contact me directly.

The thing about computer languages is that there is some weird heaviness on the actual work involved. People are scared of by codes and although they see the power, they just can't seem to get going because they have no idea where to start.

That is where training comes in. And of course, fun training. You need to be taken by hand and shown exactly what you need to do, where you need to do it, and when you need to take the right action.

The funny thing about CSS is that it allows you to create your website in the fraction of the time when you would do it using tables. It's hard to believe, but still after all these years of promotion for CSS people (and companies!) still heavily rely on tables for layout. They have no idea that they are simply wasting time on old techniques that will be useless in a matter of time.

So where do you need to pay attention on when you are looking for a CSS Guide?

1. The Teacher

The number one thing you need to be sure of is that your teacher knows where he or she is talking about. Why is he or she teaching about Cascading Stylesheet, because they need to from their boss? Because they think they can teach, no matter the subject?

Think of that, how many teachers are only "teaching" stuff, and never practice it their own? Ask yourself "why" are you teaching you me this. Are you the best in the field? Where did you get your knowledge from?

2. Teaching Style

So the teacher may be a great person, has all the required skills, has a passion for the subject and knows about everything of it. But can your teacher deliver? Does he or she KNOW how to explain things? How to take you by hand and show you step-by-step how things work?

Is it fun to follow along with the teacher? CSS is one of those topics that can become boring easily when it's only discussed in a technical way. Make sure you know what you can expect!

An even more important thing is cutting right to the case. You don't want to end up with all kind of knowledge that you will never use in practice. It simply isn't useful to learn every possible css style there is when you just get started. And this brings us to the third point you need to pay attention on when you are looking for a css guide.

3. Teaching / learning speed

Can you keep up with the course? Does your teacher decide the speed, or do you? Of course a great way to follow a course is one that allows you to define your own speed. Home study courses and guides are wonderful for that.

4. Delivery

How is your guide delivered? Are you somebody that likes to read, follow along with a training video or both? Decide what you like, training videos are great, because they allow you to follow along in a real life situation. This means hands on practice, which is exactly what you need if you want to become good in CSS.

5. Contents

Last but not least, content. What is discussed in the guide? What is marked as important? Do you get a total reference, or do you know you don't need that, that the real thing you need is a hands on course with day-to-day subjects? Decide what you want to know, just the basics, how to create full layouts, or just how to create a menu using 100% CSS.

It's up to you now, decide what you need, you know how important the 5 above points are, and where you need to pay attention on. And one last tip, make sure you get some preview videos or sample chapter before following any course, it can save you a lot of time and money at the same time.

I am using the time I alloted today to work on the real estate investor marketing in the Learn To Be Rich on-line game to lay out a framework of the steps we need to follow to get this new feature implemented into the game.

First, I will need to access the Php MyAdmin control panel and manually add in some of the sample types of marketing so that I begin to play with those with my test player in the game. My intention is to add 3 or so different ones like classified ads, bandit signs and door to door flyers.

Next, once I have those three in the database, I will need to add some code so that there is a chance each turn to learn that from our in-game Marketing Consultant. This includes adding the type of marketing to that players database table as something that is available. It also includes making sure that it shows up on the Real Estate tab as something you can work on.

Once I have it in the players database table, I need to add the code for the player to be able to modify how much to spend each turn on that type of marketing.

Next, I will need to write the code to determine the number of new houses that appear for you to look at based on the marketing you are spending money on.

Once I have this basic system working, then I will go back and add more types of marketing and tweak the interface to get the right balance in the game.

So, that is the plan right now to make the game have that new feature for modeling the marketing to find motivated sellers.
