SuperImage plugin
Greetings all,
This is the first release of the SuperImage plugin. The idea is you
upload images to the database, and then pull them out at any size you
want. Combine this with caching and it will stay light and fast.
More info and instructions are here:

Stop browser from "form filling" fields.
Hi all,
I have a user login form which the browser keeps populating because of
its form fill feature. So when anyone goes to log in it shows the
previous login''s username and password. How can I stop the browser
from populating a text field?
Thanks in advance.
Cheers,
Diego

RJS and remote forms
I''ve run into what I think is a browser bug related to using
remote_forms pushed in an RJS update.
In my controller, I have an action that creates a new model and returns
a form for one of its children:
def create_party
party = Party.create
render :update do |page|

insert_html inserting fragment twice
Has anyone had trouble with inline RJS insert_html with the latest
version of Rails?
My problem is that insert_html inserts the html fragment twice. For
example,
render :update do |page|
page.insert_html :top, "some_list", "<li>booyow</li>"
end
would render "<li>booyow</li>" twice.
Thanks.

super global dummy method for gettext + rails 2.2
Hi,
since rails 2.2 doesn''t work with gettext anymore I decided to use a

for rails 2.2. My application doesn''t need any i18n support right now
and this way i figured it would be very easy to integrate gettext
later. Just setup the plugin and go.
So I need a method called _ which is available in alle models,

nested if/else very slow, more efficient ways?
Hello,
in the data.frame "resultsfuzzy" I would like to replace the
characters in the second column ("5a", "5b", ... "5e") with numbers
from 1 to 5. The data.frame has 39150 entries. I seems to work on
samples that are << nrow(resultsfuzzy) but it takes suspicously long.
Do you have any suggestions how to make the character replacing more
