What is Open source: Definition and 55 Discussions

Open source is source code that is made freely available for possible modification and redistribution. Products include permission to use the source code, design documents, or content of the product. It most commonly refers to the open-source model, in which open-source software or other products are released under an open-source license as part of the open-source-software movement. Use of the term originated with software, but has expanded beyond the software sector to cover other open content and forms of open collaboration.

    Any suggestions for an open source Windows 10 disk encryption app

    The summary says it all, really, but in addition, I've done a lot of googling and am finding it hard to identify trustworthy options. LibreCrypt, DiskCryptor and VeraCrypt are candidates, but I have not used any of these tools so am wary of jumping in and finding that I have bricked my PC.

    C# Open Source C# Physics Library

    TL:DR; I've started an open source C# physics library: University Physics The Long Version So it turns out there's relatively little in the way of full physics libraries written in C# (the best I can find is bepuphysics which seems to be focused only on classical mechanics). With this...

    What is GNU and its relationship to Linux?
