We describe an extension of the micromagnetic finite difference simulation software MuMax3 to solve elasto-magneto-dynamical problems. The new module allows for numerical simulations of magnetization and displacement dynamics in magnetostrictive materials and structures, including both direct and inverse magnetostriction. The theoretical background is introduced, and the implementation of the extension is discussed. The magnetoelastic extension of MuMax3 is freely available under the GNU General Public License v3.

One of the features included in version 3 of the GNU General Public License (GPLv3) was a requirement, in certain circumstances, to provide ‘Installation Information.’ This was a new addition to the licence to address a ‘loophole’ that existed in version 2 of the licence (GPLv2); a loophole that was perceived as being exploited, at the time, by certain device vendors. Recently, it has been asserted that this requirement was inherent, or explicitly called for, in GPLv2. This paper examines the historical record around the time that the ‘Installation Information’ requirement was proposed, and eventually ratified, in GPLv3, to show that this requirement was understood to be both new, and not a part of GPLv2. A textual analysis of GPLv2 yields an identical result.

What is MySQL - MySQL is a database management system (English: database management system) or a multi-purpose, multi-user DBMS, with around 6 million installations worldwide. MySQL AB makes MySQL available as free software under the GNU General Public License (GPL), but they also sell under commercial licenses for cases where its use does not match the use of GPL.You can think of a MySQL database as a container that stores strings (text based) data. Images, media, files, audio files, and things that are truly natural do not have to be stored in the database. The trick is to put the file file on the server in the folder and only reference the name and path in the database

The article provides an assessment of the state of legislation of Ukraine on the protection of intellectual property at the present stage. The most important problematic aspects and prospects of improving the legal regulation of intellectual property protection on the way to European integration are described in detail. The experience of foreign countries in ensuring the protection of intellectual property is analyzed. Particular attention is paid to the features of computer program protection, which is especially relevant nowadays. Features of the use of license agreements by the owner of computer programs, namely BSD License, Apache License, GNU General Public License, GNU Lesser General Public License, were analyzed. The conclusion is drawn that a system of continuous analysis of decisions made by European countries in the field of intellectual property law, as well as on issues related to general state policy on the administration of intellectual property, in order to implement developed approaches to legislation and law enforcement practice, could improve the protection of intellectual property rights in Ukraine.

Recollimation shocks (RS) appear associated with relativistic flows propagating through pressure mismatched atmospheres. Astrophysical scenarios invoking the presence of such shocks include jets from AGNs and X-ray binaries and GRBs. We shall start reviewing the theoretical background behind the structure of RS in overpressured jets. Next, basing on numerical simulations, we will focus on the properties of RS in relativistic steady jets threaded by helical magnetic fields depending on the dominant type of energy. Synthetic radio maps from the simulation of the synchrotron emission for a selection of models in the context of parsec-scale extragalactic jets will also be discussed.

This chapter examines the development of open source computer software with specific reference to the political economy of copyleft and the legalities associated with the General Public License (GPL). It will be seen that within the context of computer software development the notion of copyleft provides an important contrast to more traditional uses of copyright. This contrast symbolizes political, economic, and social struggles which are contextualized within this chapter. As the GPL is an important legal embodiment of copyleft, its legalities are preliminarily explored so as to determine its future potential. While there is some scope to further refine the legal strength of the GPL, it will be seen that it remains a strong and subversive legal instrument which will continue to underlie open source initiatives in the years to come.
