Xataface is a flexible and shapable skin that sits on top of MySQL, making it accessible to every-day users. It automatically generates the appropriate forms, lists, and menus for a user to interact with the database without having to know any SQL. It is a full-featured Web application framework, and gives developers the flexibility to customize the features and behavior of their application via configuration files (using the simple INI-file syntax), templates, and plug-ins. A generic application with no customizations is completely functional, but the developer is free to customize things at his leisure.
Easy I18N is a library that integrates GNU gettext with the JVM's internationalization facilities. Existing Java APIs (MessageFormat, DateFormat, Locale) are used to provide a much easier API for building and maintaining applications and Web apps. It includes the ability to use normal message strings in your code, use xgettext to auto-extract translatable strings, leverage the GNU gettext system and associated tools to manage translations, work with date, currency, and numeric input/output, supports thread-local Locales for Web apps (or global for apps), and more.
rxvt-unicode is a clone of the well known terminal emulator rxvt, modified to store text in Unicode and to use locale-correct input and output. It also supports mixing multiple fonts at the same time, including Xft fonts, real transparency, and an optional embedded Perl interpreter that allows you to extend your terminal easily.
FastFormat is a C/C++ output and formatting library whose design parameters are complete type-safety, efficiency, genericity, and extensibility. It is simple to use and extend, highly portable (to any platform or compiler), and it upholds the C tradition of you only pay for what you use. FastFormat supports output and formatting of statements of arbitrary complexity, consisting of heterogeneous types. FastFormat writes to output "sinks", which can be of arbitrary type.
