drawthe.net draws network diagrams dynamically from a text file describing the placement, layout and icons. Given a yaml file describing the hierarchy of the network and it's connections, a resulting diagram will be created.

Describe your diagrams with a simple text language and automatically generate an image you can export.
Why?

You love diagrams but don't want to spend time positioning elements.

Your diagram keeps evolving, you want the layout to re-adjust automatically.

You prefer to describe your diagrams with an intuitive text description.

SQL::Translator is a group of Perl modules that manipulate structured data definitions (mostly database schemas) in interesting ways, such as converting among different dialects of CREATE syntax (e.g., MySQL-to-Oracle), visualizations of schemas (pseudo-ER diagrams: GraphViz or GD), automatic code generation (using Class::DBI), converting non-RDBMS files to SQL schemas (xSV text files, Excel spreadsheets), serializing parsed schemas (via Storable, YAML and XML), creating documentation (HTML and POD), and more. New to version 0.03 is the ability to talk directly to a database through DBI to query for the structures of several databases.

Through the separation of the code into parsers and producers with an object model in between, it's possible to combine any parser with any producer, to plug in custom parsers or producers, or to manipulate the parsed data via the built-in object model. Presently only the definition parts of SQL are handled (CREATE, ALTER), not the manipulation of data (INSERT, UPDATE, DELETE).
