message: This is written for those who use Boolean applications in electronics and computers, and those taking classes in Boolean logic in school.  It is not intended for PhDs in mathematics.  The article Boolean algebra is written with that audience in mind. StuRat 13:35, 18 September 2005 (UTC)
thread_title: Intent of this article

message: I still want to work on the transitions between sections, which I expect to finish within a week. StuRat 13:18, 18 September 2005 (UTC)
thread_title: New article is under construction

message: I will take any suggestions for changes to this article under advisement.  I would prefer if you wait a week before making major changes yourself.  If you find a spelling error, etc., please go ahead and fix it yourself, though. StuRat 13:19, 18 September 2005 (UTC)
thread_title: Suggested changes

message: Here's a list of things I would like to add:
A) Applications:
:1) Digital computers - bit and image manipulation using Boolean operations. Provide links for right shift, left shift, 1's complement, and 2's complement; but don't spend any time on them.
:2) CAD - union / intersection / subtract /splits (performed using element of "n-1" dimensions) , etc.
::a) 2D CAD/drafting/drawing/architecture software - such as patterns for wood paneling having the area inside a window frame subtracted.
::b) 3D surfacing packages
::c) 3D solid modeling packages
:3) Database - discuss "UNION" and "UNION ALL" SQL statements
B) Transitions:
:1)Transition into sets
:2)Transition out of sets - talk about Boolean algebra of two elements/states to transition to truth tables.
C) Graphics
:1) Provide links for each symbol to an image page (for use by those with browsers which don't support set notation symbols).  Also add text explaining the links.

thread_title: To add

message: I'm going on vacation this week, so won't have much opportunity to do editing.  In the meantime, I would like to know what everyone thinks about the links I added for some of the symbols, so readers on browsers which don't support those characters can pick the link to view the image.  I'd have preferred to put the pics directly in the text, to avoid the problem in the first place, but Wiki doesn't seem to do pics as part of text very well. StuRat 02:31, 25 September 2005 (UTC)
thread_title: Temporary pause

message: I still do not concur \pm is always OR, and sometimes XOR.  Discussion? Arthur Rubin | (talk) 00:16, 30 November 2005 (UTC)
thread_title: <math>\pm</math> and XOR

message: I was reading a book about electronic logic design, and it stated without giving any examples that: "in fact there are 16 possible boolean functions of two variables (2 input gates), but in practice only six are commonly used, AND, OR, NOT, NAND, NOR and XOR". I can find no further information about this - what on earth are the other ten? Try as  I might I can't really imagine them, unless they are trivial ones such as always 1 or always 0... anyone got any insight into this, or were the book authors wrong?
