Placing legal or practical restrictions on the comprehension or modification of a program, such as mandatory purchase of special licenses, signing of a Non-Disclosure-Agreement (NDA) or - for programming languages that have multiple forms or representation - making the preferred human way of comprehending and editing a program ("source code") inaccessible also makes it proprietary (non-free). Without the freedom to modify a program, people will remain at the mercy of a single vendor.
Although the term free software had already been used loosely in the past,[11] Richard Stallman is credited with tying it to the sense under discussion and starting the free-software movement in 1983, when he launched the GNU Project: a collaborative effort to create a freedom-respecting operating system, and to revive the spirit of cooperation once prevalent among hackers during the early days of computing.[12][13]

Apart from these two organizations, the Debian project is seen by some to provide useful advice on whether particular licenses comply with their Debian Free Software Guidelines. Debian doesn't publish a list of approved licenses, so its judgments have to be tracked by checking what software they have allowed into their software archives. That is summarized at the Debian web site.[32]
Merely mentioning the existence of export regulations, without making them a condition of the license itself, is acceptable since it does not restrict users. If an export regulation is actually trivial for free software, then requiring it as a condition is not an actual problem; however, it is a potential problem, since a later change in export law could make the requirement nontrivial and thus render the software nonfree.

In any given scenario, these freedoms must apply to whatever code we plan to make use of, or lead others to make use of. For instance, consider a program A which automatically launches a program B to handle some cases. If we plan to distribute A as it stands, that implies users will need B, so we need to judge whether both A and B are free. However, if we plan to modify A so that it doesn't use B, only A needs to be free; B is not pertinent to that plan.
Welcome to's Free Software section, a roundup of the Web's hottest, most essential freeware. The software we list here is all totally free, and (unlike shareware), has permanent full functionality. This software won't throw any annoying "nag" screens at you, asking you to register. And most importantly, it won't expire after 30 days! Shareware is good, but freeware is even better!
Everyt business runs on opportunity. It runs on the potential of the new prospects that could turn into paying customers. These incoming prospects are called sales leads and they hold a strong place in the success of a company. So today we ask whether or not buying sales leads is the right decision to help your company grow, or if free sales leads are the way to go. Let’s look into the basic terms before we dive into the whole ordeal:
A special issue arises when a license requires changing the name by which the program will be invoked from other programs. That effectively hampers you from releasing your changed version so that it can replace the original when invoked by those other programs. This sort of requirement is acceptable only if there's a suitable aliasing facility that allows you to specify the original program's name as an alias for the modified version.
In 1983, Richard Stallman, longtime member of the hacker community at the MIT Artificial Intelligence Laboratory, announced the GNU project, saying that he had become frustrated with the effects of the change in culture of the computer industry and its users.[27] Software development for the GNU operating system began in January 1984, and the Free Software Foundation (FSF) was founded in October 1985. An article outlining the project and its goals was published in March 1985 titled the GNU Manifesto. The manifesto included significant explanation of the GNU philosophy, Free Software Definition and "copyleft" ideas.
To define the first term, one that you probably already know or, at least, should know, a sales lead is an inbound prospect that shows an interest in the company and has purchasing potential to make a sale. Sales leads go through your marketing campaign’s sales process, through lead tracking and nurturing efforts to reach the end goal: conversion. While it can be a long process, each sales lead is different and can take different strategies to work to convert. Some simply come with more potential than others, and some will not prove to be successful for your company in the end. This will happen no matter how you work to generate leads, there will never be a 100 percent success rate, and that is okay. Just work to convert the ones with the most potential with the help of lead management software and you will find the sales numbers your company needs.
Copyrights are a method of protecting the rights of the creator of certain types of works. In most countries, software you write is automatically copyrighted. A license is the authors way of allowing use of their creation (software in this case), by others, in ways that are acceptable to them. It is up to the author to include a license which declares in what ways the software may be used. For a proper discussion of copyright see
