   • Software Freedom in FOSS (Free and open-source software)

     Free Software or Libre (Libre is the most common Spanish adjective for “free”) software are the softwares that allows user to do to any kind of work he/she wants as well as he can modify, add new features and he has freedom to distribute the changed version also. A software is said to be free if it gives user ultimate freedom to do things the way he wants.

     The term “free software” is sometimes misunderstood—it has nothing to do with price. It is about freedom. Here, therefore, is the definition of free software: a program is free software, for you, a particular user, if:

     Examples: The Free Software Directory maintains a large database of free-software packages. Some of the best-known examples include the Linux kernel, the BSD and Linux operating systems, the GNU Compiler Collection and C library; the MySQL relational database; the Apache web server; and the Sendmail mail transport agent.

   • What is the purpose of a license for open-source or free-software?

     Top Answer

     Answered May 23, 2017 · 2 votes

     My question is, what is the purpose of a license for such code?

     The purpose of a license is that you have a document where it is written down which rights you grant with your copyrightable work (software can fall under copyright).

     This helps users of your software to understand which rights they have with the software.

     A Free Software License allows users to use, study, share and improve your software. This is the same for those Approved Licenses listed on the website of the Open Source Initiative.

     So without a license you do not give many rights. A license clarifies which rights are granted. This is the first benefit for you: Users of your software don't need to ask you first.

     Does it stop them from using it?

     No, a license is not stopping from using it. At least normally not. A license grants the rights needed to make use of the software therefore its actually the opposite.

     Or if they can still use it, does it (the license) benefit me in any way?

     What do you mean by still use it? They can use the software if you provide a (known) software license. The benefit for you is that you tell so it's clear what you give.

     If yes, in what ways?

     For example by clarifying that you provide the software AS-IS without warranties of some kind. If you look into the licenses you find a passage about exactly that.

     If I don't use any license for my source-code, is that a bad idea? To put it differently, would I regret in future if I don't use any license for my source-code which I release to the public?

     Yes, this is generally a bad idea because you more or less do not tell your users which rights they've got with the software. That can have negative influence on usage patterns and contribution patterns. That's something you might regret in the future.

   • What is difference between open development and open source?

     Top Answer

     Answered Jul 09, 2019 · 1 votes

     In the Adobe AEM teams we work a lot on Apache projects. As we like the Apache way we tried to apply the same project management principles to our internal closed source projects.

     The key principles are "power to those who do" and "community over code". The result is kind of a shared responsibility for the projects. Everyone can participate in development of all code bases. You start by reporting bugs and improvement requests but you can also provide the solution in form of pull requests. If you do good work you are usually also allowed to do commits yourself and drive the direction of the project.

     At Adobe this development style works very well as people are used to the Apache way. If you want to apply this in other companies be careful. A big part of the success is to establish the culture which is not guaranteed to work and takes a lot of time and effort.

   • What is a good free (open source) BLAS/LAPACK library for .net (C#)?

     Top Answer

     Answered Sep 21, 2009 · 12 votes

     AMD's ACML is a free download, but it is binary only, not open source, and native code, not .NET.

     Performance is generally superior to the Netlib.org code, and generally roughly the same as Intel's MKL -- which is not free IIRC.

     The download includes one sample that demonstrates how to bind it to C#. Not any different from calling any other C or C++ library from C#.

     Library implements BLAS, LAPACK, FFTs, and RNGs.

     http://developer.amd.com/cpu/Libraries/acml/downloads/pages/default.aspx

     EDIT TO RESPOND TO COMMENT:

     On an Intel CPU, AMD's ACML will perform approximately as well as Intel's MKL, but it depends on the algorithm, matrix sizes, number of cores, memory topology and speed, etc. etc. etc. Your mileage may vary. The only way to tell for sure is to run your own benchmark. In some cases, ACML is faster than MKL even on Itel hardware.

     Either one will be significantly faster than any "naive" implementation for large matrixes. Both are architected to use multiple threads on multicore processors, and have hand-tweaked assembly language kernels and a lot of tuning for the cache behaviours on various machines.

     For small matrixes, performance is generally a don't-care, since any modern cpu can solve a small matix in just a few milliseconds, even using the simplest code. In that case, you're only using a library to avoid writing and debugging code that has been written hundreds of times already.

   Free and open-source software (FOSS) is software that is available under a license that grants the right to use, modify, and distribute the software, modified or not, to everyone free of charge. The public availability of the source code is, therefore, a necessary but not sufficient condition.

   Jan 1, 2024 · “Free software” means software that respects users' freedom and community. Roughly, it means that the users have the freedom to run, copy, distribute, study, change and improve the software. Thus, “free software” is a matter of liberty, not price. To understand the concept, you should think of “free” as in “free speech,” not as in “free beer.”
