Why switch to Apollo to display HTML and dynamic content when a browser already allows it? Why use Joost Net TV to see if a browser already allows it?
Why has not the producer of two simple browser functions within them:
- Windowless windows
- P2P Object
Windowless windows
This simple feature would make the most of the HTTP connection and make it really useful browsers. To open windows (pop-up in practice) with only the title and no border, just in case in transparency, increase the production of widgets to be exploited with the normal browser, like what he does now Apollo . With a careful study on the safety (as I think it is now the only reason for this limit) would open up very interesting scenarios.
P2P Object
As we all know by now all browsers support the object XMLHttpRequest , which has given rise to an endless amount of so-called Ajax applications. This object can be accessed via JavaScript, is able to provide an HTTP channel - parallel - scriptable client for both IINV and receiving data.
Sooner or later, as anticipated in various other blog, Adobe will insert a P2P in Flash. Why not do the same thing in the browser? An object of this type together with Windowless features allow you to create applications like Joost-without installing anything on your machine, ensuring cross-compatibility worthy of the Internet, thereby increasing the efficiency of production (now Joost is developed for each system operational, which is quite heavy - both in money and time - in fact, the beta will follow ...).
RSS FEED short windows with text, audio and video from the place where we want on our desktops, in true W3C standards. Open TCP channels are directly from JavaScript, with endless possibilities of data exchange. Clearly, the will is little and the "crime" is high, hackers, spam and phishing are lurking and moves of this kind terrorize a bit 'all ...

Who has recently updated WordPress is strongly encouraged to move urgently to version 2.1.2 . According to Secunia the problem of the last update of WordPress 2.1.1 is considered highly critical, allowing remote PHP code execution! Visit the official blog for more details on how to update the story, since it is the Italian version for some files there are special procedures to be performed.
Also for the first start in console security issues. A vulnerability in Microsoft Xbox 360 gaming console, in fact, would be the execution of foreign code, and the replacement of the internal software with Linux! The update to resolve everything has been distributed via Xbox Live.

A characteristic of the style sheets (files. Css) is to be specified depending on the output medium. The Style Sheets allow you to specify the same class, the same the same ID tag, etc. ... for different media. For example, I can write a file. Css with the following syntax:
1
2
3
4
5
6
7
| @ Media screen {
display : none } div # mybox {display: none}
}
@ Media print {
display : block } div # mybox {display: block}
} |
non sarà visibile sul browser, sullo schermo, ma quando provo a stampare la pagina troverò un contenuto diverso da quello che mi aspettavo. What it comes at the end, is that the content of the DIV with id myBox will not be visible on the browser screen, but when I try to print the page will find a different content from what I expected.
Search engines, spiders, crawlers and aggregators, usually (for now) do not solve the css file. They are interested in viewing the content not the formatting. However, this technique could have interesting implications if not disturbing. Because of the characteristics of systems of indexing a situation like the one shown below would be at least curious:
1
2
3
4
5
6
7
| "visibile_a_video" > < div id = "visibile_a_video"> p > < p > Content visible on the screen </ p > </ div > "visibile_in_stampa" > < div id = "visibile_in_stampa"> p > < p > Content visible in print </ p > </ div > |
Correlated with a file. Css like this:
1
2
3
4
5
6
7

| @ Media screen {
display : block } # visibile_a_video div {display: block}
display : none } div # visibile_in_stampa {display: none}
}
@ Media print {
display : none } div # visibile_a_video {display: none}
display : block } # visibile_in_stampa div {display: block}
} |
Google, for example, both index the contents of our HTML, even if the screen we can see only one. If we print the page you will find a surprisingly new content. The trick, however, would be revealed by eliminating the application of styles in browsers that support it. Normally no one performs an operation of this type when surfing the Internet. This survey occurs only after finding a mismatch between what is visible on the screen and what was printed!
To date I have seen no cases of this type of blatant manipulation using CSS. At one time it tried to increase the visibility on the Internet using a series of texts, words, of the same color as the background of the Web page, thus making this obscure artifice in the eyes of navigators. By the time the engines are indexing guard against these "fraud". Maybe it's time to anticipate some joker before you set a precedent?
Currently Style Sheets allow you to specify a range of output media type. For a complete list see the W3C .

I want to pick an interesting Post by Thomas Tessarolo titled " If YouTube is gone , "an argument that is very curious and disturbing in some respects. Not long ago, during an episode of Quark Piero Angela, has discussed the consistency of digital information in relation to the neo-digital photography. In recent years digital photography has clearly eclipsed traditional photography with the introduction of cameras in mobile phones and digital cameras to lower costs of good quality. There was, therefore, a radical change in the management of the photographs that are on CD, DVD - or the PC itself - their ideal of conservation, preservation and display. The main question that arose from the transmission was: Will our children or grandchildren to see the "old" CD with our pictures?
I still have faded Polaroid of the seventies, as I happened to recall photographs - really old - taken between 1940 and 1960! While these photos have lost momentum and the time has left its mark, no doubt remains that were preserved more or less discreetly over more than half a century. Also I had no problem for "display", being proposed on a substrate analog! If we consider that I can not read disks written 3 inches and a quarter in 1995, the issue could begin to be worrying.
ALEXANDRIA DOT NET
What happened to the library of Alexandria , a fire that destroyed an important heritage that no one is now able to quantify, it is perhaps a repeatable event? What would happen if an electromagnetic wave befell enough power on earth could reset all the digital information stored today? Sure, there would be many other problems, see bank accounts, stall (or collapse) of the western economy, etc. ... etc. ... a real massacre. However, this - remote - possibility is accumonata the same way as an environmental disaster caused by the fall of an asteroid! Is it true?
The circle is closed
What could be accessed in a certain sense, quite curious. Among the services offered online on the Internet, blogs are the most popular. Imagine what would happen if the server of our blog shut or suffer an injury - including backups! Blogs (The Post) are usually written directly online, there is no local copy, at least I, for example, do not possess it (I will provide ...).
We should start thinking to print on all issued post so he can one day rebuild the blog compared to a total destruction of digital material. The digital, therefore, is no longer safe or analog?
A printed photograph is subject to wear and tear, dust, light, etc. ... However, even a CD or DVD is damaged, despite maintaining the data in a way - apparently - more stable (not sure) of any other analog media.
It seems the only solution is to use the digital, even for archival purposes, but at the same time continue to use the classic mode of storage.
Analog -> Digital -> Analog
The books, for example, have a duration long enough if we consider that even today you can read texts dating before Christ! In addition, some information is not lost with time. In a photograph, for example, information is the predominant light, the tones, the photo itself. This, on a substrate analog, is therefore subject to greater wear. In a book, however, information is more stable and lasting. A text with pages worn at the edges or yellowed by time and continues to lie completely still its main information: the text.
However, this solution a return to analog can be applied with a certain simplicity in very specific contexts, such as pictures or text precisely. The music and other digital information typically require alternative approaches to implementation is not simple. A piece of music, for example, can be stored in the form of the score, as a set of sheets of paper, but it is not a copy of the original. Videos are too complex to be stored in other forms.
In my opinion this is a very important topic in a digital age such as ours. The fact that there are no precedents in this regard allertino that there is not a sufficient excuse to not think about it carefully. If ever a disaster were to occur Digital important proportions, here are springing up like mushrooms and company initiatives to the preservation of digital data.
Why wait for the inevitable and not think of a solution right now?

First of all, as mentioned in the Post encryption system RSA is a public key encryption and takes advantage of the properties of prime numbers. Moreover, the arithmetic used (in the calculations) is not the ordinary, but the so-called finite or artirmetica modular. Let's start right from the latter to proceed step by step in the implementation of RSA encryption.
