Vlado Cingel is Rails developer from Croatia. Apart from Ruby & Rails, I really enjoy scripting in JavaScript and converting designs into great HTML & CSS.
It is pretty simple to get number of work days between two dates. For example we can get the number of workdays in this month.
start_date = Date.civil(2010, 8, 1)
end_date = Date.civil(2010, 8, 31)
workdays = (start_date..end_date).select { |day| ![0, 6].include?(day.wday) }.size
I recently published a plugin that helps you turn any textarea into a markup editor. It is based on excellent markItUp! jQuery plugin.
The most simple usage with preset defaults
<html>
<head>
<%= javascript_include_tag "path/to/jquery" %>
<%= mark_it_up '#miu_test' %>
</head>
<body>
<% form_tag do %>
<%= text_area_tag "miu_test" %>
<% end %>
</body>
</html>
You can see a lot more cool examples in action on markitup.cingel.hr.

SimpleSearch brings simple search to ActiveRecord. It ads simple_search named scope that accepts query as parameter.
The idea is that you provide the query and plugin does the rest (splits query to keywords and compose where statement).
This can be very useful in case you just want to filter list of records by some query, you have autocomplete field, … or something similar.
My neighbourhood was hit by flood today. We managed to prevent the water from entering the house, but it was a great reminder how powerful mother nature really is :)
