We are getting out feet wet into the CSS. We know the basics of how it works, now we need to understand some hairy, but fundamental concepts, like how to position our elements correctly. There is a range of ways on how to do this, because each element might behave differently, and a combination of all of these methods will allow us to create some amazing websites, with everything where we wanted to be.

Before we continue let’s give our website a little extra touch that makes difference. …

Usually, when designing a new website, developers usually start with a color palette and a font scheme for the website. Both are responsible for the feel of the website because those properties have a strong emotional connection with the readers.

Good typography can make your website gorgeous to look at and can mesmerize people to look at simple things like your CV. In the same way, misused typography can ruin even the best websites. …

When creating our website we use HTML to structure it, and for a while, HTML was the only tool to create websites. But don't look down on HTML yet, this still a great tool to structure your website, but if you wanna do more advanced customization on your website, things can get tricky pretty fast, and using HTML to stylize is a very error-prone method.

Cascading Style Sheet

Here where CSS comes to save the day. It is a mechanism to stylize our HTML code. …


We already have the foundation, so let's build upon it.

We already know how few basic elements work, now we are gonna start to increase the complexity of our tools.

Even tho we know how to place items like images, hyperlinks, and paragraphs, where they appear on the web site still in a messy way. To structure better our site using just HTML, we are gonna use the table element.

It’s important to know that we use CSS to change the layout, since HTML 4 the usage of HTML elements to structure the page has been discouraged.

To start developing anything we first need to understand how a website works, whats are their main components.

Whenever you access a site, you type some catchy name on the URL bar press enter, and then boom! A gorgeous site appears in front of you, but underneath the table, a lot is going on.

What is a VPC?

Basically, AWS will rent you a logically isolated part in their data center. You will have total access and control over resources and permission. You can control who accesses what. You can think of it as a Facebook account, you control the content that is posted and also the person that you share with.

When you create an AWS account, a “default” VPC is created for you.

VPC Basics

You can find an example of VPC pretty close, actually, every home internet is a VPC.


From a total newbie point of view.

I’m just getting started inside this universe called AWS. I’m taking a course in A Cloud Guru and this is my studies notes, they might not make much sense now, but I’m putting all my knowledge here. This will not be too useful for those who already master Cloud Computing, but might help those who are beginners like me.

If you went to Brazil 7 years ago, besides the fantastic landscape, the fabulous food, and the happiest people I've seen so far, you probably would notice something odd. In any personal card that someone gives to you, and in most store facades, there would be two, three, and sometimes even four telephone numbers!

That's because SMS was expensive, and the providers had extra fees for calling other providers. I remember choosing the provider; I had to evaluate the person I mostly talk to and get the same company as they do. Because of that limitation, it was pretty convenient…


“Our greatest strength and also the source of our weakness.”

A few days ago, I was watching a video about Paulo Leminsk, a famous Brazilian poet. The video shows one of his text and touched me profoundly. I wish to share with you the text and what I've learned.

“Slaves and masters.Nobles and peasants.Employers and employees. Technicians and workers. Nothing distinguishes humankind from animals more than the division of labour—our greatest strength and also the source of our weakness.

Because of the division of labour, humankind was able to multiply its power over nature at a remarkable rate. Only 30.000 years ago, all that we had to face the hostility…
