GNU GPLv3 At the Heart of the Black Hole Image (www.tfir.io) 56

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.

    Maybe free software already won the "software wars", now I think there should be a fight against the "close source cloud".

      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 adequat

      I appreciate good tools like everyone else but leave culture politics out of it, for example from the article: It’s a victory of diversity in the era of homophobia and sexism.

      What are you talking about? There isn't a "war", and commercial software developers are not your enemy, we all use the same tools to get the job done. This is the dumbest us-versus-them-ism. Software licensing is an extremely good motivator to create quality software, deal with it.

    • now I think there should be a fight against the "close source cloud".

      There are multiple open source cloud projects and many corporate providers using these projects. Shop around. Or if you have a decent internet connection, download OwnCloud or Seafile and host it yourself.

    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.

      between engineers and scientists.

      Engineers are paid to deliver commercial products as quickly and cheaply as possible with little regard to actual knowledge ... until the company gets sued. There will be exceptions.

      Scientists are paid to solved questions with testable and repeatable solutions. There will be exceptions.

      How ironic! That's what I'm doing today. It would really be nice if scipy.io.loadmat would import nested MATLAB structures structures without a bunch of hacks. [stackoverflow.com]

    you read it right – GNU GPL v3

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

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

      Yeah but the G in GNU means GNU so what we've really got here is the GNU Not Unix Not Unix Not Unix Not Unix Not Unix {caught buffer overflow exception} GNU Not Unix Not Unix Not Unix Not Unix Not Unix {caught buffer overflow exception} Proprietary License. ... Version THREE!

        Your buffer overflows appear to be part of an exploit to replace "Public" with "Proprietary". Better scratch and restore from backups.
    • 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

      I suspect the reason some people think this is remarkable is that a bunch of projects (like the Linux kernel) make a big deal out of staying on v2.

  • i would be surprised if NO open source software would have been used.

Real programmers don't comment their code. It was hard to write, it should be hard to understand.
