The CFS site is designed to cater to those requirements – good quality, genuinely free software (freeware) which has been checked and rated – programs I use and ones which you will want to use too. While descriptions are brief, there is usually much more information in the CFS Program Review and on the program’s homepage (where the link will usually take you).
This could be the most high-end free software ever: it's the very tool used to render the images you see in Pixar's movies. That's because RenderMan was developed by Pixar in-house for that purpose, but became free for non-commercial use. It's not going to do you much good without other software such as Autodesk's Maya for creating 3D models. But budding artists and filmmakers will want to take note. You'll need a 64-bit system to run it.
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.
Proprietary software uses restrictive software licences or EULAs and usually does not provide users with the source code. Users are thus legally or technically prevented from changing the software, and this results on reliance on the publisher to provide updates, help, and support. (See also vendor lock-in and abandonware). Users often may not reverse engineer, modify, or redistribute proprietary software. Beyond copyright law, contracts and lack of source code; there could be additional shenanigans keeping users from exercising freedom over a piece of software, such as software patents and digital rights management (more specifically, tivoization).
There is debate over the security of free software in comparison to proprietary software, with a major issue being security through obscurity. A popular quantitative test in computer security is to use relative counting of known unpatched security flaws. Generally, users of this method advise avoiding products that lack fixes for known security flaws, at least until a fix is available.
On February 3rd 1998, in the wake of Netscapes announcement to release their browser as Free Software, a group of people met in Palo Alto in the Silicon Valley and proposed to start a marketing campaign for Free Software using the term ``Open Source.'' The goal was to seek fast commercialisation of Free Software and acceptance of Free Software by the companies and venture capitalists of the booming new economy. As a means to this end, they made a conscious decision to leave aside all long-term issues (such as philosophy, ethics and social effects) related to Free Software, feeling these posed obstacles in the way of rapid acceptance by economy. They proposed to focus on technical advantages only1.

We are back again, this time testing... Apple’s Mac OS X. [...] While the results were reasonable, we were disappointed to find that the reliability was no better than that of the Linux/GNU tools tested in 1995. We were less sure what to expect when testing the GUI- based applications; the results turned out worse than we expected.
Each directory represents a one-time investment from the agency to set up a profile. Each listing represents a possible lead generation opportunity. While there are thousands of agencies listed in those directories, businesses may have the option to set up themselves in more curated directories. For examples, HubSpot's agency directory lists only 600 agencies.
The best thing about some of these companies is that you don't have to "Like" them on Facebook, send messages on Twitter, or complete surveys. With the companies I've listed first, simply sign in, input your mailing information, and wait for the free sample to show up in your mail). It will take less than 15 minutes sign up and up to six weeks for samples to arrive.
