What I had to do was:

1) ssh to the machine where I wanted to deploy the application to

2) ssh to the git repo machine and accept the key

Done.

sudo gem1.9 install kwatch-mysql-ruby 
              --source=http://gems.github.com/ 
              -- with-mysql-config=/usr/local/mysql/bin/mysql_config

Where in the –with-mysql-config option you have to specify the path to mysql_config in the bin directory in your mysql installation path.

In Mobile Interactive Technology we are trying to make our new applications compatible with Rails 2.3 and Ruby1.9. Not an easy task though. An invaluable source of info on compatibility of gems with Ruby1.9 is isitruby19.com.

Check some pictures on Flickr.

attr_accessor :attr_name

Here is the code we have written. Basically all you need to do is add the sub attr_accessor to your Perl class, and then call this method with the attribute you want the getter and setter for.

package MyPackage;
 
sub new {
  my $class = shift;
  bless {}, $class;
}
 
sub attr_accessor {
  $attr = shift;
  eval <<ATT;
  sub $attr {
    my \$self = shift;
    my \$value = shift;
    if( \$value ) {
      my \$old_value = \$self->{ $attr };
      \$self->{ $attr } = \$value;
      return \$old_value;
      } else {
        return \$self->{ $attr };
      }
    }
ATT
}
 
attr_accessor 'name';

In the code above we have added accessors methods for the attribute ‘name’. We can then set and get the ‘name’ attribute as in the following code:

my $t = new MyPackage;
$t->name('marco'); # setter method
print $t->name # this will get and print 'marco'

Enjoy!

In my previous post I talked about the work I carried out for my MSc research project. Here is the Wordpress plugin that implements a simplified version of the summarization system described there.

This plugin creates an automatic excerpt of a post when it is saved or published. The excerpt created is a coherent piece of text containing the most important sentences of the post.
After installing this plugin, every time you write a post and press the save or publish button an excpert is created for that post and stored in the database. This plugin is useful also if you don’t use excerpts in your blog: it’s always useful to have a summary of your post available just to remind yourself what the post is about (it works very well with old and long posts!).
Statistical natural language techniques are used to extract the most important sentences from a document. It’s straightforward to tweak the plugin to give more importance to certain features in your text.
The code of the plugin has been optimized for extensiblity in order to make it easy for contributor developers to implement a summarizer in their own language. At the moment only an English language summarizer is available, and an Italian one is on its way.
After activating the plugin here are simple steps that you might want to follow in order to have a nice excerpt to use in your blog:

1. Write your post
2. Press the save or publish button
3. An excerpt will be created. Now you can review it, modify it and save it as many times as needed
4. If you want the summarizer to create an excerpt again delete the existing one and press save or publish

Note that the plugin creates automatically an excerpt for a post only if there isn’t already an excerpt for that post.
