Escaping characters
Hi,
I am writing some help about post formatting. I am using redcloth to
format the text, and in a FAQ, also formatted with redcloth, I explain
what to type to what to obtain.
So, how could I escape ''*'', ''#'' & Co, to have an output like
<redcloth>
Type *word* to obtain <strong>word</strong>

Questions on ActiveRecord implementation
Hi,
I got several questions on AR adapters implementation:
1. For SqlServer/Oracle, SQL queries are built by concatenation, and
there is no use of parameters. Especially for Oracle, this is very bad,
no optimization can be done. Is there a reason for that? Does anybody
plan to fix that?
2. When updating a model, _all_ columns are updated. Why not only the
diff is updated? Using blob/cblob, it

Generating RTF documents?
Hi,
I need to implement some RTF export for a customer. According to some
"templates", i generate RTF documents, filling data coming from models.
It''s pretty much like a mailmerge, but in *nix/ruby world.
Also, customer would like (in the future) to upload himself the
templates, so he can modify them by his own.
Can anyone advice me on an elegant solution?
Thank you,

Storing large BLOBs in the database with ActiveRecord
I have a model called Product with an attribute called file of
type :binary (DB BLOB). If I do product.save (where product is an
instance of my Product model), here is SQL statement that the mysql
adapter for Ruby will do:
INSERT INTO `PRODUCT` COLUMNS(NAME, PRICE, FILE) VALUES(''PROD1'',
4.56, X''00DEF033423023220'')
All is hunky dory for as long as my BLOB is

MultiMarkdown and MathML - new feature and request for help
A lot of people have expressed interest in combining math features
with Markdown, but I am not aware of any real developments from these
requests.
I was looking around and toying with [ASCIIMathPHP](http://
www.jcphysics.com/ASCIIMath/) and integrated it with MultiMarkdown
and my xhtml2latex XSLT transforms.
You can include math as an inline formula by using a markup similar

Hello,
I''m trying to create categories that have their own subcategories, and each
subcategory may have its own subcategories, .. and so on.
After some reading, I found out that the best way for creating such a thing
is to use acts_as_tree, but I didn''t find any tutorial or article that
