Open Source Python System Shells

Petaapan is exploring the opportunities that multi-touch displays present. Initially we are looking at tools to support agile development to provide a concrete target for the investigations.

Sakura is a Knowledge Navigator and User Interface for UNIX, which implements HyperMedia and its own windowing and packing system, both in the main program and in an extensive API for Tcl and other languages.

FLoM is a free open source distributed lock manager that can be used to synchronize shell commands, scripts and custom developed software. When used in a shell environment, FLoM manages process synchronization in the same way that "nice" manages process prioritization. Shell commands, scripts and custom programs can be synchronized inside a single system or in a network of IP connected systems. FLoM supports different types of abstract resources: simple, numeric, set, hierarchical and transactional sequence. libflom, the library shipped with FLoM, allows you to develop your own application using a simple C, C++, Java, Perl, PHP or Python client API. SSL/TLS security for network communication, X.509 certificates for peer to peer mutual authentication.

The **libmsgque** project is an infrastructure that allows multiple package-items to be linked together to act as one application. To link, you need to distribute the work from one package-item to another package-item and wait for an answer or not. > Philosophy: Write Once → Run Everywhere The package-item can be a thread, a separate local process that is started by fork or spawn, or even a network of multiple services on multiple hosts. The package-item can be written in any language that is supported by the Programming-Language-Micro-Kernel support. It even supports running multiple programming languages in a single piece of software. Supported Languages are: (C,C++,C#,VB.NET,Java,Python,Ruby,Perl,PHP,Tcl or GO) > Strategy: It takes 4 years to write a programming-language, but it only takes 4 weeks to insert a micro-kernel. The package-item is connected to one another via a pipe or a socket and is based on packets .
