GNU GPLv3 At the Heart of the Black Hole Image (www.tfir.io)

arnieswap quotes TFIR's report on the black hole image: Free and Open Source software was at the heart of this image. The team used three different imaging software libraries to achieve the feat. Out of the three, two were fully open source libraries. The source code of the software is publicly available on GitHub.

Richard M Stallman, the founder of the GNU Project will be glad to see that both libraries (Sparselab and ehtim) are released under GNU GPL v3. Yes, you read it right – GNU GPL v3.

      Free software has won the software wars in academia, and in servers. Everywhere else is still dominated by proprietary software. (Handhelds are a mixed bag, because most of them run Android, and there is AOSP, but many of them can't run it. Etc.)

      What it's going to take for FOSS to take over the rest is the same thing it always was going to take. It's going to require that some people sit down and apply that last 50% of effort on the last 10% of the software, and polish it up. It's going to take some adequate kiddie-level documentation. It's not the hot, new and sexy. It's the practical and necessary.

    I've worked at a national institute in Europe and worked on software for reading out infrared cameras for space-observing satellites. Everywhere around me, both scientists and engineers, were replacing (or trying to replace) Matlab and other commercial software with Python. There were some Fortran holdouts, but these were also migrating to Python. Software engineers used C++ for the core, but these were little nuggets that shoved data from custom electronics to ethernet, and then Python would pick up the packets.

    For some specific stuff, especially electronics engineers were not replacing Matlab. For instance to model electromotors. Mechanical engineers likewise. I never knew what they were using, but open source was not used anywhere at our institute. But the rest: Python, NumPy and SciPy.

    AFAIK, the v3 of GPL is partially in response to companies trying to do content distribution platforms using open source software. The content owners are very particular about having DRM, and the platforms on which that content is distributed have to provide some sort of secure boot chain that prevents unauthorized software from running on the *hardware*. Those companies comply with the open source GPL v2 license and publish their source code for others to use, but they do not allow modifications of that source code to run on their hardware.

      It was because Tivo abused hardware locking to prevent any modification of the GPL based software they were providing. The freedom for users to modify software, "free as in speech", is one of the most critical aspects of "free software" licenses like the GPL. Tivo used GPLv2 software but locked its users hands by applying hardware based lockin, which was a direct violation of the spirit of the GPL.

    Why is it remarkable? Is it because it is weird since the G of GPL already means GNU?

    While the initial "G" in GNU does mean GNU (GNU is a recursive acronym for "GNU's Not Unix"), the "G" of "GPL" stands for "General"—General Public License. The GNU GPLs are so widely used and discussed that one can get away with saying "GPL" to mean one or more versions of the GNU General Public License. 'General' here means not specifically written for a particular GNU program. When GNU started different GNU programs had their own license—GNU Emacs General Public License for GNU Emacs, for example. It's not hard to see how this approach doesn't scale up well. The GNU GPLs are the license for many GNU programs. Today GNU GPL v3 is the latest such license and the license itself and GNU's pages about that license make it clear that the proper full name of this license is "GNU General Public License".
