Thrift Delphi Software Library

. Delphi Lightweight, language-independent software stack for point-to-point RPC implementation. Thrift provides clean abstractions and implementations for data transport, data serialization, and application level processing. The code generation system takes a simple definition language as input and generates code across programming languages that uses the abstracted stack to build interoperable RPC clients and servers. Thrift makes it easy for programs written in different programming languages to share data and call remote procedures. With support for 28 programming languages, chances are Thrift supports the languages that you currently use.

REXX

REXX is a programming language originally developed by IBM and over time included in all IBM operating systems (e.g. OS/2, AIX and PC DOS). In addition to this, various IBM and non-IBM implementations have been made available for most operating systems/environments (including free implementations for Win32/Win64, Linux, Mac OS X, Solaris and many others - e.g. Regina, Open Object Rexx). This interface unit makes it possible to inter-mix code written in Pascal with REXX.

All Things Ubuntu Library

ATU Library (All Things Ubuntu Library) is a collection of libraries in Object Pascal for use with FreePascal and Lazarus IDE, that provide API dedicated to various versions of Ubuntu, including: - standard desktop Ubuntu - Ubuntu Mate ARM (ie. raspberry pi) - Ubuntu Touch/UBports Since most of resources available for Lazarus programmers are related to Windows OS, this library is aiming at addressing those interested in Linux programming with FPC and Lazarus, but tested with Ubuntu distributions. On Ubuntu Touch, you can install everything from the Terminal app or via ssh, either or will work. Just follow these steps: #download: $ wget https://sourceforge.net/projects/all-things-ubuntu-library/files/ATU_arm-linux.tar.gz #extract: $ tar -xf ATU_arm-linux.tar.gz #install ATU locally: $ ./ATU_arm-linux --install #you also recommended to install dependencies like this: $ sudo ./ATU_arm-linux --installdeps #if you're using Vivid this will also f
