STMX is a high-performance Common Lisp library for composable Software Transactional Memory (STM), a concurrency control mechanism aimed at making concurrent programming easier to write and understand. Instead of traditional lock-based programming, one programs with atomic memory transactions: if a memory transaction returns normally it is committed. If it signals an error, it is rolled back. Transactions can safely run in parallel in different threads, are re-executed from the beginning in case of conflicts or if consistent reads cannot be guaranteed, and effects of a transaction are not visible from other threads until committed. This gives freedom from deadlocks, automatic rollback on failure, and aims to resolve the tension between granularity and concurrency.
QueryFS is a FUSE-based virtual filesystem that is based on queries. There are plugins to parse various query syntaxes and each query creates a virtual directory. Currently the most elaborate query language is SQL-based; you can either provide access to data stored in an SQL database, or keep an index of files in the SQL database and generate search directories with symlinks to found files. QueryFS and its SQL2 query DSL fully support creation of refinable searches: for example, the author has an index of downloaded email files; one can see all the distinct senders registered in the DB and then go into a directory of one sender and see all accounts that ever received an email from this sender.
DSWM (Deep Space Window Manager) is a tiling keyboard-driven X11 window manager. It is based on StumpWM code and is written entirely in Common Lisp and oriented for good usability with minimum startup configuration and good integration with Emacs. The project is under hard development, so it has many experimental features.
Common Lisp Quick Reference is a booklet with short descriptions of the thousand or so symbols defined in the ANSI standard. It comes with a comprehensive index. It is written in LaTeX and formatted for printing on both A4 and letter paper. After folding the sheets lengthwise, they can easily be turned into a handy booklet.
Design Center is a Web application that allows users to change the colour of different layers in a photo. In a photo of a bedroom, there could be layers for the walls, the ceiling, and for the floor. The application lets users change the colour of each and see how a new paint job would look. If used on a furniture store's Web site, different layers could be used for beds, chairs, lampshades, etc. to allow customisation by users.
otl is a text processor for generating markup from readable lightweight markup. Much of both the input and output formats can be customized. HTML output is bundled as an example. otl supports complex structures such as nested ordered and unordered lists, headers and footers, and tables.
