The lab was very informative and educational. Their talks centered around the Google License Verification Library which enables developers to tamper proof applications in an effort to make reverse engineering of applications much more difficult.

Other information covered was the backward compatibility of features released in Android 4.0, Ice Cream Sandwich, which are able to be back ported using the Android Support Package so that developers don’t have to worry so much about version compatibility.

The new WiFi Direct standard was covered and the appropriate API’s required to access these communication features. Android Beam was also covered with it’s associated API’s. Overall this was an informative presentation from Google and I hope to be included in future labs.

On Ubuntu, as opposed to Windows, each virtual host is configured in a separate file within the /etc/apache2/sites-available/ directory. Typical virtual host boilerplate would look similar to below (For more detailed specifications please refer to the Apache Virtual Host Documentation):

<VirtualHost *>

ServerAdmin webmaster@localhost
ServerName dev.kromosome.net
ServerAlias www.dev.kromosome.net
DocumentRoot /var/www/dev.kromosome.net/public

<Directory />
Options FollowSymlinks
AllowOverride All
</Directory>
<Directory /var/www/dev.kromosome.net/public/>
Options Indexes FollowSymLinks MultiViews
AllowOverride All
Order allow, deny
allow from all
</Directory>
<FilesMatch “\.(htaccess|htpasswd|ini|phps|fla|psd|log|sh|svn|git)$”>
Order Allow,Deny
Deny from all
</FilesMatch>
ErrorLog /var/www/dev.kromosome.net/logs/error.log
LogLevel warn
CustomLog /var/log/apache2/access.log combined
</VirtualHost>

If I were to save the above boilerplate code into a file called dev.kromosome.net inside the /etc/apache2/sites-available/ directory I have effectively defined a virtual host. To enable access to the site I need to issue the following command:

%>sudo a2ensite dev.kromosome.net

At this point, any attempt to access dev.kromosome.net will try to resolve the domain so we must now instruct the browser to resolve the domain locally. To do this, open the /etc/hosts file and add the following line to the file and save it:

127.0.0.1 dev.kromosome.net

If you have previously tried to access your site through the browser you will need to clear your browser cache before the domain name will attempt to resolve the address locally. You have now completed configuring an Apache virtual host.

adb pull sdcard/[folder-name]/file.txt C:\Users\your-user-name\Desktop\filename.txt

You will be asked to rebuild the project based upon the compiler settings that you specify, after which you should see the error disappear.

The new version corrects a defect in the init() function that created an extra unnecessary array dimension. A new function, getJSON() has also been added, this function converts the array data to a JSON data type.

<div>
    <input type="radio" id="active_true" name="active[]" value="active" /><label for="active_true">Active</label> 
    <input type="radio" id="active_false" name="active[]" value="inactive" /><label for="active_false">Inactive</label>

$(function()
{
    //Firstly, upon document ready we call the jQuery .buttonset() function on the containing div
    //to style the jQuery UI element, like so:
    $('#activations').buttonset();
 
    //we will set a variable to test against but generally this will be a program input
    //in our case, we must test against the radio button's value being 'active' or 'inactive'
    var someValue = 'active';
 
    //next, we'll get a reference to the button array
    var btnActive = $('[name=active[]]');
    $(btnActive).each(function() 
    {
        // test the value of the radio against our variable
        if( $(this).val() == someValue )
        {
            $(this).attr('checked', true);
            $(btnActive).button("refresh");
        }
    }):
});

The most important aspect of this code is the call to the .button(“refresh”) method. Without this, you will not see any visible change to the UI radio button’s selected state.

{css} designerGrid is a css prototyping tool for web developers.

If you scroll to the bottom right of the window you will see the {css} designerGrid control where you can toggle the grid and columns on & off. You can also set the grid index. When the grid is on top of the site content, you can click anywhere to get the mouse coordinates.

To see a more eye pleasing implementation, you can see one here.
