Easy As Abc: Categorizing Open Source Licenses
EASY AS ABC: CATEGORIZING OPEN SOURCE LICENSES Andrew T. Pham1, Matthew B. Weinstein2, Jamie L. Ryerson3 With more than 180,000 open source projects available and its more than 1400 unique licenses, the complexity of deciding how to manage open source usage within “closed-source” commercial enterprises have dramatically increased.4 Because of the complexity and risks associated with open source—where source code is made freely available for all to review, edit, and use—many closed-source commercial enterprises discourage or prohibit use of open source; a common and short-sighted practice. With a proper open source management framework, open source can be an invaluable resource, and its risks can be understood, managed and controlled. This article proposes a simple, consistent and effective open source categorization and management system to enable a peaceful coexistence between open source and closed-source codes. Free and open source software (“FOSS” or collectively “open source”) is a valuable tool, but one that must be understood to be used effectively. The litany of risks associated with use of open source include: having to release a derivative product incorporating open source under the same open source license; incorporating code that infringes a patent; violating an open source license’s attribution requirements; and a lack of warranties and indemnities. Given the extensive investment of time, money and resources that goes into product development, it comes as no This article is an edited version of the original, which dealt not only with categorizing open source licenses but also a wider array of issues associated with implementing an open source policy. -

However, running on Linux, ROS does not provide real-time guarantees, while real-time tasks Received in revised form are required in many robot applications such as robot motion control. This paper for the first time presents 20 April 2015 a real-time ROS architecture called RT-RTOS on multi-core processors. RT-ROS provides an integrated Accepted 12 May 2015 real-time/non-real-time task execution environment so real-time and non-real-time ROS nodes can be Available online 9 June 2015 separately run on a real-time OS and Linux, respectively, with different processor cores. In such a way, real-time tasks can be supported by real-time ROS nodes on a real-time OS, while non-real-time ROS nodes Keywords: Real-time operating systems on Linux can provide other functions of ROS. -

Open Source Licenses Olivier Dony @odony Agenda o Brief history: GPL and Copyleft o AGPL vs LGPL o Licenses of Odoo 9 o Combining licenses Brief history: GPL Before 1980, most programs were distributed with source code by default (for portability, bugfixing, auditing, etc.) Most software came from an academic background Then the situation changed. GPL = Copyleft Copyleft relies on universal Copyright laws to enforce freedom for a piece of work The Free Software Foundation defines four freedoms: use, modify, distribute, and distribute modifications To guarantee these freedoms to every user, GPL forbids any restriction coming from other licenses Brief history: GPL 1983: Richard Stallman creates GNU 1989: GPLv1 is born (bin + source, no restrictions) 1991: GPLv2, LGPLv2 (“liberty or death”, C-lib) 1999: LGPLv2.1 (library -> lesser) 2007: GPLv3, LGPLv3, AGPLv3 (DRM, tivoization, wording, patents) Brief history: Odoo 2005: TinyERP 1.0-4.0 – GPLv2 or later 2009: OpenERP 5.0 – GPLv3 or later + OEPL (web) 2011: OpenERP 6.0 – AGPLv3 + OEPL (web) 2012: OpenERP 6.1 – AGPLv3 2012: OpenERP0 0 0 7.02 – AGPLv3 5 0 2014: Odoo 8.0 – AGPLv3 0 2 2015:0 Odoo1 0 2 9.0 – CE: LGPLv3 + OE AGPL GPL is a strong copyleft license, but it suffers from the ASP loophole (Cloud) => 4 freedoms are only enforced if distributed AGPL was created to fix this, by adding the Section 13 provision: Copyleft applies as soon as users are interacting remotely with the program LGPL GPL is a strong copyleft license, but lacks a linking exception => Unsuitable for libraries, such as the C lib LGPL was created to fix this, by adding a linking exception on top of GPL “Using/Linking” in any program is OK if the LGPL part can be modified/replaced. -
