Wi-fi-blocking wallpaper set for launch

 Wi-fi-blocking wallpaper set for launch

Just because you're paranoid doesn't mean they're not after you. Or, indeed, trying to fry your brains with electronic waves.

If you come out in a cold sweat at the thought of all the invisible waves pinging around your four walls - and don't fancy clambering into a Faraday cage for some protection - then you might be due a spot of redecorating.Wi-fi-blocking wallpaper (image © Centre Technique du Papier)

Researchers at the Centre Technique du Papier have come up with a wallpaper that blocks wi-fi and mobile phone signals. Slap this stuff all over the walls, floor and ceiling of your bedroom and you'll create a haven that takes you back to a time before phone networks and the mobile internet even existed.

Well, it's one way to stop your partner from making those bedtime Facebook updates.

The wallpaper - dubbed Metapaper by its creators - only blocks wi-fi and mobile phone signals. So your incoming FreeView TV signal, for instance, can still get through your walls.

Although it's likely to be most useful in places where ringing mobiles and other electromagnetic disturbance is a genuine problem (such as theatres, concert halls and hospitals) Metapaper is also set to be made available for private purchase.

As well as blocking signals coming in, it also blocks your own signals from going out - so you could also look at this as adding an extra level of security, since your wi-fi network could potentially be limited to just your own home.

The team behind the wallpaper says it works by using conductive ink that filters out the specific frequencies that carry mobile phone (GSM) or wi-fi signals (0.9, 1.8 and 2.1 GHz for mobile phones, 2.45 and 5.5 GHz for wi-fi).

It's set to go on sale next year at a price that should be no higher than what you would expect to pay for mid-range wallpaper. The technology could also be integrated into plasterboard, wood or floor coverings.

What is HTML?

What is HTML?

HTML is a computer language devised to allow website creation. These websites can then be viewed by anyone else connected to the Internet. It is relatively easy to learn, with the basics being accessible to most people in one sitting; and quite powerful in what it allows you to create. It is constantly undergoing revision and evolution to meet the demands and requirements of the growing Internet audience under the direction of the » W3C, the organisation charged with designing and maintaining the language.
The definition of HTML is HyperText Markup Language.
  • HyperText is the method by which you move around on the web — by clicking on special text called hyperlinks which bring you to the next page. The fact that it is hyper just means it is not linear — i.e. you can go to any place on the Internet whenever you want by clicking on links — there is no set order to do things in.
  • Markup is what HTML tags do to the text inside them. They mark it as a certain type of text (italicised text, for example).
  • HTML is a Language, as it has code-words and syntax like any other language.

How does it work?

HTML consists of a series of short codes typed into a text-file by the site author — these are the tags. The text is then saved as a html file, and viewed through a browser, like Internet Explorer or Netscape Navigator. This browser reads the file and translates the text into a visible form, hopefully rendering the page as the author had intended. Writing your own HTML entails using tags correctly to create your vision. You can use anything from a rudimentary text-editor to a powerful graphical editor to create HTML pages.

What are the tags up to?

The tags are what separate normal text from HTML code. You might know them as the words between the <angle-brackets>. They allow all the cool stuff like images and tables and stuff, just by telling your browser what to render on the page. Different tags will perform different functions. The tags themselves don’t appear when you view your page through a browser, but their effects do. The simplest tags do nothing more than apply formatting to some text, like this:
<b>These words will be bold</b>, and these will not.
In the example above, the <b> tags were wrapped around some text, and their effect will be that the contained text will be bolded when viewed through an ordinary web browser.
If you want to see a list of a load of tags to see what’s ahead of you, look at this tag reference. Learning the tags themselves is dealt with in the next section of this website, My First Site.

Is this going to take long?

Well, it depends on what you want from it. Knowing HTML will take only a few days of reading and learning the codes for what you want. You can have the basics down in an hour. Once you know the tags you can create HTML pages.
However, using HTML and designing good websites is a different story, which is why I try to do more than just teach you code here at HTML Source — I like to add in as much advice as possible too. Good website design is half skill and half talent, I reckon. Learning techniques and correct use of your tag knowledge will improve your work immensely, and a good understanding of general design and the audience you’re trying to reach will improve your website’s chances of success. Luckily, these things can be researched and understood, as long as you’re willing to work at it so you can output better websites.
The range of skills you will learn as a result of running your own website is impressive. You’ll learn about aspects of graphic design, typography and computer programming. Your efficiency with computers in general increases.You’ll also learn about promotion and your writing will probably improve too, as you adapt to write for certain audiences.

Do I have to be online all the time?

Not at all. You can code your entire website offline, storing it all on your own computer, and then just transfer all the files onto the web. Then whenever you have new content, you just add that to the existing online version of your site. It’s really quite simple.

Is there anything HTML can’t do?

Of course, but since making websites became more popular and needs increased many other supporting languages have been created to allow new stuff to happen, plus HTML is modified every few years to make way for improvements.
Cascading Stylesheets are used to control how your pages are presented, and make pages more accessible. Basic special effects and interaction is provided by JavaScript, which adds a lot of power to basic HTML. Most of this advanced stuff is for later down the road, but when using all of these technologies together, you have a lot of power at your disposal.
