Lawsuit threatens to break new ground on the GPL and software licensing issues

Filed under
OSS
Legal

GPLv2 is one of the most widely used FOSS licenses, if not the most. It is the license for some of the most important and commercially valuable FOSS projects, including the Linux kernel, whose contributors include such uncomfortable bedfellows as Oracle and Google, Intel and AMD, and Cisco and Huawei. If XimpleWare is right, and a license under GPLv2 offers no protection from the licensor's patents, Linux would be a landmine for these companies, and really for any company with fewer patents than IBM.

Even without an explicit patent grant, lawyers advising businesses on FOSS issues generally agree that GPLv2 protects licensees (at least those in compliance with the license terms) from patent suits by licensors. This is because the law provides for an implied license (or judicial estoppel) where a licensor's conduct leads the licensee to believe it will not be sued, or where fairness otherwise demands that the licensor should be prevented from suing. Because the GPL encourages licensees to copy, modify, and distribute the licensed software—all conduct that would infringe any patents on the software absent a license—licensees can reasonably expect that the software's producers won't sue them for doing those things. (Adam Pugh and Laura A. Majerus of Fenwick & West discuss GPLv2's implied patent license in greater detail in this paper.)

With mid-term evaluations just around the corner for many technology-focused summer internship programs, here's a closer look at how the Google Summer of Code (GSoC) and Outreach Program for Women (OPW) are helping mentors as well as interns.

Xen Project virtualization is one of 40 open source projects involved in the OPW program run by the GNOME Foundation. This open source software is a Linux Foundation collaborative project that develops the Xen Hypervisor (for x86 and ARM), the XAPI toolstack, and the Mirage OS Cloud Operating system.

SAP embraces opens source -- sort of

Filed under
OSS

At the annual OSCON (Open Source Convention) last week, those stuck in a worldview of open source from the previous decade would have suffered serious cognitive dissonance.

First, Microsoft was an anchor of the conference, with a full-scale display from Jean Paoli's subsidiary Microsoft Open Technologies. As I walked past I repeatedly heard people expressing shock that Microsoft was there at such scale. Wholehearted support for open source still largely stops at the boundaries of Microsoft's Azure cloud offering, but plenty of staff people with genuine open source credentials were showing their wares. Microsoft's journey is definitely progressing.

The great Ars experiment—free and open source software on a smartphone?!

Filed under
Android
Google
OSS

Android is a Google product—it's designed and built from the ground up to integrate with Google services and be a cloud-powered OS. A lot of Android is open source, though, and there's nothing that says you have to use it the way that Google would prefer. With some work, it’s possible to turn a modern Android smartphone into a Google-less, completely open device—so we wanted to try just that. After dusting off the Nexus 4 and grabbing a copy of the open source parts of Android, we jumped off the grid and dumped all the proprietary Google and cloud-based services you'd normally use on Android. Instead, this experiment runs entirely on open source alternatives. FOSS or bust!

For those excited about the recent working Radeon R9 290 "Hawaii" Gallium3D support, a number of bug-fixes were committed in recent hours to Mesa for bettering the support for those wishing to use this open-source AMD Linux driver for their ultra high-end graphics hardware.

Open-source AMD Linux users wishing to use a Hawaii GPU will still need to utilize the patches that will not be queued up until the Linux 3.17 kernel (along with updating their Radeon microcode files) but the RadeonSI Gallium3D Mesa improvements are starting to hit the mainline tree.

Eclipse Luna for Fedora 20

If you are a Fedora Eclipse user, then you're probably saddened since the release of Eclipse Luna (4.4) because you are still using Eclipse Kepler (4.3) on Fedora 20. Well, be saddened no longer because Eclipse Luna is now available for Fedora 20 as a software collection! A software collection is simply a set of RPMs whose contents are isolated from the rest of your system such that they do not modify, overwrite or otherwise conflict with anything in the main Fedora repositories. This allows you install multiple versions of a software stack side-by-side, without them interfering with one another. More can be read about this mechanism on the software collections website. The Eclipse Luna software collection lives in a separate yum repository, which must be configured by clicking on this link to install the release package. Read more
