The R Project for Statistical Computing -- alternative to Excel.
First up is R&R's (created by Robert Gentleman and Ross Ihaka) R Project, or simply 'R', which is a downloadable software environment used for statistical computing and graphics.

The software provides statistical and graphical techniques, including linear/non-linear modeling, time-series analysis and classical statistical tests among a host of others. The software is compatible with most OSs and will run on various UNIX platforms, Windows and MacOS-based PCs. R is also open-source software, enabling users to modify it at will to suit their needs without the fear of litigation.

In the article number 7. The author wrote this app is free but it is not.

For viewing Gerber files I recommend GC-Prevue from www.graphicode.com.  It is a free Gerber file viewer.  They also have other more-capable purchasable tools.

Add QUCS to the Free Design Tools

Quite Universal Circuit Simulator (QUCS) is a great little Spice-like open-source tool that runs quickly, has a wide range of components, rather intuitie interface (but a so-so manual), and will execute S-parameter analysis. Available at qucs.sourceforge.net/.

I've used Eureqa by www.nutonian.com, sounds similar.  There's a useful but limited free version.

I have tried FreePCB couple of times, it is not bad for most projects with 16 layers or less. Some features I wish it had are viewing Gerber files, import/export of DXF files and print capability!

What is the basis of this ranking?

Is this ranking based on a survey of engineers? If so, what is the size of the sample and how was the sample chosen?

:-)  Yes, it can be a rare commodity when engineers interact with non-engineers!  Oh, well, c'est la vie!

I cannot disagree.  I suppose I've been lucky a lot of the time; I usually have the opportunity to insist that things are done properly.  I don't take that for granted. ;)

Not disputing that.  But time is a constraint that must also be accommodated...and meeting the schedule is not always "not good engineering." 

 

I think we have to meet in the middle here.
