Attack the DNS

After doing my research here they are my conclusions:

DNS (Domain Name System) is an Internet service that translate domain names  into IP addresses. That means, it translates human language into computer language, names into numbers.

Example: DNS translates www.google.com in its IP adress. Try to type 70.42.251.42 in your browser! 

It is unpractical that we users would memorise IP address of every website. There is where domains come to play.  The DNS is its own network. Every time you use a domain name, a DNS service must translate the name; if a DNS service doesn’t know how to do it, it asks to another one and so on until the correct address is returned. 

I have done a little diagram to explain it more visual:

HTML tags exercise

<div> 

The div is a generic block-level element. It doesn’t convey any meaning about its contents (unlike a p element that signifies a paragraph, or an h1 or h2 element that would indicate a level 1 or level 2 heading, respectively); as such, it’s easy to customize it to your needs. The div element is currently the most common method for identifying the structural sections of a document and for laying out a web page using CSS.

<blockquote> 

The blockquote element is a mechanism for marking up a block of text quoted from a person or another document or source. It may be just a few lines, or it may contain several paragraphs (which you’d mark up using nested p elements).

<p> 

The p element is one of the most commonly used building blocks of HTML. When you use the p element to begin a new paragraph in HTML, it automatically creates some space above and below the content. This space is applied by the browser’s built-in style sheets, but you can override it as you see fit using CSS.

<ol> 

The ol element is similar to the ul element in that it’s used to group a collection of items together in a list. Each list item is defined by a li element, which suggests an order of importance or sequence, as ol is an abbreviation of ordered list. The ol may be used to mark up a series of steps that someone has to undertake, a table of contents, or a numbered list of references.

<ul> 

The ul element, the name for which is an abbreviation of unordered list, is used to group a collection of items together in a list, but in a way that doesn’t suggest an order of precedence or importance. The ul might be used for anything from a simple shopping list to a collection of links.

<li> 

The li element defines an individual list item and can only appear inside the handful of list-related elements detailed above. Each list item is represented by a bullet (for unordered lists, defined by the ul element) or a number or letter (in the case of ordered lists, defined by the ol element).

<nav>

The <nav> tag defines a section of navigation links.

Not all links of a document must be in a <nav> element. The <nav> element is intended only for major block of navigation links.

Browsers, such as screen readers for disabled users, can use this element to determine whether to omit the initial rendering of this content.

<menu> 

The menu element was originally intended to be used to display lists of menu choices, and is almost identical in its purpose to the dir element (except that, unlike dir, the menu element was not intended for multicolumn display).

Like the ol and ul list types, the menu element contains a series of li items.

<span> 

For an element that offers no semantic information about the content inside and also provides no styling change, or any other visual change to speak of, the lowly span element is one of the most useful elements in your HTML toolbox.

<time>

The HTML <time> tag is used for declaring the date and/or time within an HTML document.

<q> 

The q element is little brother (or sister) to the blockquote element. Where blockquote creates a distinct block of quoted text, the more svelte q element is used for inline quotations. It’s intended that the browser should insert the necessary quotation marks, the style of which should depend on the language of the document or that section of the document, rather than the author adding quotation marks, which can cause double quotation marks to appear.

<img> 

The img element provides a means for embedding an image in the document, which can be used for as many different purposes as your imagination allows. With just the couple of required attributes shown in the example, the img provides a reference to the image file to display, and a text alternative should the image not be available for whatever reason

WEBCRAFT CHALLENGE

I have just getting embarked in an exciting new project, to build my very first website. I am going to start my learning almost from zero so I think this program will really help me. Webmaking 101 Community seems the best place to help me in what I need in this moment, a learning plan with community integrate with people that are sharing the same experiences.

This is not going to be easy but I am very committed and looking forward to learn all about in this interesting world!

SOPA, ACTA AND SOME REFLECTIONS

It has been a few weeks since almost SOPA was approved, the law to stop online piracy introduced by USA government. When I say almost I mean it will be in force if had it not been for the huge protest that raised from all over the network and that made cancel the approval of the law. However they continue with the determination to implant their exigencies. They recently get out to the public knowledge a law called ACTA,Anti-Counterfeiting Trade Agreement, that had been negotiated for the past 3 years in secret by 39 countries.

All that laws confuses people. At least, I am confused. I don´t know how exactly will affect me in the future and that´s what I am trying to figure out. I did my research, I talk with my friends and I read individuals opinions in Internet. It is a complex issue and they try to complicate even more with their intelligible language, but it was not difficult to come to the conclusion that internet world as we know it will finish. All files of series, movies, songs and books which content copyrights and had not been paid for them will be eliminated for the net. Ultimately, free knowledge is restricted. Here it is a link to a YouTube´s video that has been much spread and explains the situation much better than me: ANTI-ACTA - What can you do? (I am not sure if I could share this link with ACTA been active)

We are in front of a real big problem in here. I truly believe they are completely wrong.  They should realise that business model has changed. We are into an interactive age, the share of knowledge in essential. Businesses have always adapted to the news requirements of the market and that´s what leads them to grown up. Let´s take the example of Trent Reznor, a singer who success understanding how the world is working now. He left his record lab and started working next to his fans being aware of their needs and offering them what they request, and of course making money at the same time. If you are interested you can take a look at this video, it is really remarkable: http://www.youtube.com/watch?v=Njuo1puB1lg

In my opinion, instead than create a law which forbids any kind of sharing, it would be more appropriated to create a system where this sharing could be developed inside a legal frame.
