Sometimes you need to encode special characters in your projects. – I often do, while writing in Portuguese that uses “special” Latin characters. For those cases there is a standard rule called ISO-8859-1
ISO-8859-1 is the default character set in most browsers.
The first 128 characters of ISO-8859-1 is the original ASCII character-set (the numbers from 0-9, the uppercase and lowercase English alphabet, and some special characters).
The higher part of ISO-8859-1 (codes from 160-255) contains the characters used in Western European countries and some commonly used special characters.
Entities are used to implement reserved characters or to express characters that cannot easily be entered with the keyboard.
Reserved Characters in HTML
Some characters are reserved in HTML and XHTML. For example, you cannot use the greater than or less than signs within your text because the browser could mistake them for markup.

WordPress News – PHP4 and MySQL4 R.I.P.
Our approach with WordPress has always been to make it run on common server configurations. We want users to have flexibility when choosing a host for their precious content. Because of this strategy, WordPress runs pretty much anywhere. Web hosting platforms, however, change over time, and we occasionally are able to reevaluate some of the requirements for running WordPress.
Now is one of those times. You probably guessed it from the title — we’re finally ready to announce the end of support for PHP 4 and MySQL 4!
How to use custom styles in the Word Press post editor
Every-time I created a word press theme, I felt the need to allow my theme users to use on their contents, the CSS styles that I had created to the theme itself.
They were especially created in order to maintain a visual identity between the layout and the contents, and should be directly applied at the author’s will! – How-come the styles, created specially for that theme (my CSS Classes), weren’t available to be applied trough the default WYSIWYG text editor?
My objective was allowing users to be able to apply the custom styles, in the default panel, using the panels own logic, without any particular knowledge of HTML or CSS and without having to stick to the editor’s default predetermined styles.
In this brief tutorial I’ll explain a very simple way to do this, just by adding a couple of lines of code to your theme’s functions.php, and by creating a very simple CSS file to host your custom styles.
In my previous article about this subject (www.wdmac.com/word-press-custom-css-styles-in-the-wysiwyg-editor) we’ve edited a couple of WP core files, and the result was satisfactory. However those edits where lost on every WP upgrade, and that was not satisfactory at all. This is a clean, straightforward technique, that is “permanent” and non-upgrade-dependent.

App Inventor is a new tool in Google Labs that makes it easy for anyone—programmers and non-programmers, professionals and students—to create mobile applications for Android-powered devices. And today, we’re extending invitations to the general public.
For many people, their mobile phone—and access to the Internet—is always within reach. App Inventor for Android gives everyone, regardless of programming experience, the opportunity to control and reshape their communication experience. We’ve observed people take pride in becoming creators of mobile technology and not just consumers of it.
For the past year, we’ve been testing App Inventor in classrooms around the United States, and we’ve found that it opens up the world of computer programming to students in new and powerful ways. David Wolber, professor of computer science at the University of San Francisco and part of the initial pilot program, says “students traditionally intimidated by technology are motivated and excited to program with App Inventor.” One student from Professor Wolber’s class told us: “I used to think that no one could program except CS people. Now, I’ve made dozens of applications for the Android phone!” Another student, who struggles with dyslexia, was inspired by App Inventor to take more computer science classes and is now learning Python. Check out this video to hear more about App Inventor for Android at University of San Francisco.
