Crawler, spider, bot, or whatever you want to call it, is a program that automatically gets and processes data from sites, for many uses.
Google, for example, indexes and ranks pages automatically via powerful spiders, crawlers and bots. We have also link checkers, HTML validators, automated optimizations, and web spies. Yeah, web spies. This is what we will be doing now.
Actually I don’t know if this is a common term, or if its ever been used before, but I think it perfectly describes this kind of application. The main goal here is to create a software that monitors the prices of your competitors so you can always be up to date with market changes.
You might think “Well, it is useless to me. You know, I’m a freelancer, I don’t have to deal with this ‘price comparison’ thing.” Don’t worry, you are right. But you may have customers that have a lot of competitors they want to watch closely. So you can always offer this as a “plus” service (feel free to charge for it, I’ll be glad to know that), and learn a little about this process.
So, let’s rock!Read More
I hope you have heard a little about CSS3 and HTML5. And I’m sure you’ve used at least one of the cool features they offer. But now it is time to use them at their full (or almost full) power.
You may be asking yourself “It is time to change? Should I forget everything I know and dive into this new world?”. Well dear padawan, you don’t need to do so. We have a lot of tools that make our transition to new and better technologies safer (ultimately we can’t just crash our customer’s website, we have bills to pay :D).
Frameworks are helpful with this. They’ve already been tried, tested and proven. Of course, you can always make them better, but they are a really good starting point.
This time we will talk a little about frameworks and other tools, like generators and templates.
So, let’s rock.Read More
Today our task is to create a simple WordPress plugin to relate posts as a series. With this, when you create a new post it is automatically listed in your series, so if a user is reading any post of the series he can jump to others, even posts created after that one he is reading.
It may seem a bit too simple, but with this we can learn a lot about:
1. Custom post types
2. Custom fields
6. Basic plugin structure for WordPress
7. Little bit of jQuery
So, let’s rock!

Today we will get a perfect and simple blurry menu effect via CSS. In addition to it, we will get a useful multiple borders effect. To achieve this effect you will need to have a basic understanding of HTML and CSS. We will work with IE filters and text-shadow, but there is no reason to worry if you have never used it, they’re all well and simply explained.
And the best part is that anything done here works almost anywhere, from IE6 to real browsers.
So, let’s work!Read More

The IT industry is full of tough challenges for developers who are one step away from creating new forms of interaction. The trend of web scripting is growing rapidly and developers are striving to develop web pages which automate more tasks on a website. The benefit of client-side scripts is that HTML supports it regardless of the language that is used for scripting. By using these scripts, developers are able to introduce plenty of highly active ways to enhance HTML documents.Read More
