kongcurrent provides an easy-to use helper to assist debugging issues which cause exceptions under concurrent access. It was inspired by a problem in which a non-thread-safe Map object held by a third party framework was accidentally shared between threads, causing a ConcurrentModificationException. The helper (a "monitor") creates a proxied version of an object implementing some interface. The proxy can track invocations of the objects' methods and can report on potential concurrent access on the object. This can be used to help find code paths which concurrently access the object through its interface methods. By design, the helper is extensible, and can be adapted to more specific needs.
lambdaj is a Java library that allows you to manipulate collections in a pseudo-functional and statically typed way. The main purpose of lambdaj is to partially eliminate the burden of writing (often nested and poorly readable) loops while iterating over collections. In particular, it allows you to iterate a collection in order to filter its items on a given condition, convert each item with a given rule, extract a given property from each item, sort the items on the values of one of their properties, group or index the items on the value of one or more properties, invoke a method on each item, or aggregate the items or the values of one of their properties. It allows all this without having to write a single explicit loop.
LASIC is a language that facilitates creating and managing systems in a cloud environment. It allows you to create scripts that describe a system, its components, and the relationship between those components using a declarative syntax. Various verbs can then be applied to the script such as deploy (create a new system), shutdown, or runAction(run some action on components of the system). LASIC currently supports Amazon's cloud environment (AWS). LASIC stands for Language for Automating Systems in the Cloud.
lib4d_sql is a C library that provides the required functions (connect, prepare, execute, etc.) for writing an SQL client for 4D databases. It uses the public 4D SQL protocol, which is supported by 4D products since version 11. It is already used by the PDO_4D Open Source project, and it might be used to provide others drivers for JDBC, ADO, or ActiveRecord.
libapache2-mod-scramble-ip is an Apache 2 module that works like mod_removeip, but instead of just overwriting the IP address with 127.0.0.1, it encrypts the IP address. This way you always get an IP address to work with (in scripts, etc.) and have the ability to use tools like awstats to analyze your logs. It's in alpha status, but working on some Apache 2 servers, and the 'cost' (load) should be small and reasonable.
