Asymptote is a powerful descriptive 2D and 3D vector graphics language for technical drawing, inspired by MetaPost but with an improved C++-like syntax. It provides for figures the same high-quality level of typesetting that LaTeX does for scientific text. Asymptote is a programming language as opposed to just a graphics program. It can exploit the best features of script (command-driven) and graphical user interface (GUI) methods. High-level graphics commands are implemented in the language itself, allowing them to be easily tailored to specific applications.
The QtLua library aims to make Qt 4 applications scriptable using the Lua scripting language. It is an alternative to the QtScript module. QtLua does not generate or use generated binding code for Qt. Instead it provides useful C++ wrapper classes to make C++ and Lua objects accessible from both Lua and C++. It takes advantage of the Qt meta object system to expose QObject members to Lua scripts and comes with user manual and examples.
MBFL is a collection of libraries for the GNU Bash shell. It is an attempt to make GNU Bash a viable solution for medium sized scripts. A set of modules implementing common operations and a script template are offered by this package. The author has used them with success in implementing non-small scripts.
libnodelay is an LD_PRELOAD library for disabling Nagle's algorithm. Disabling Nagle's algorithm can result in a performance improvement for latency-sensitive applications that use TCP. Using the library may be easier than digging through a mess of code and confusing or obscure configuration options.
Pybatis lets you use a templating engine to generate SQL in the same way we use templating engines to generate HTML. But while HTML is generated to send to a browser, Pybatis generates SQL to send to the database via Python's DB API, and then gathers the results. Pybatis consists of three things combined: Python's DB API, templates, and convenience methods. The core idea of treating dynamic SQL as a templating problem rather than a code generation problem (as in most ORM libraries) comes from iBATIS, after which Pybatis is named with great respect.
Duplicati is a backup system and an implementation of Duplicity. Duplicati enables you to set up and monitor backups on Windows or Linux. Duplicati is based on the Linux-only Duplicity backup system. Duplicati has a very user friendly interface that allows you to configure and monitor your backups. It supports backing up to a variety of destinations, such as a network folder, a USB disk, a remote FTP server, a remote SSH server, Amazon S3 storage, or a WebDAV enabled server. All backups can be encrypted and are digtally signed, so that no other person can read or tamper with the backed up data.
