• 05:1605:16, 20 January 2012 diff hist +93‎ Arthur Eddington ‎ →‎Fundamental theory: synthesis included cosmological considerations; also added more about E-numbers

30 December 2011

• 01:4101:41, 30 December 2011 diff hist +185‎ Boole's expansion theorem ‎ →‎Example: fixed example, improved wording, and enlarged
• 01:2501:25, 30 December 2011 diff hist −1‎ Boole's expansion theorem ‎ →‎Expansion
• 01:2401:24, 30 December 2011 diff hist −9‎ Boole's expansion theorem ‎ →‎Expansion: fixed capitalization and sentence fragments
• 01:2001:20, 30 December 2011 diff hist +5‎ Reed–Muller expansion ‎ fixed missing subscript (important for understanding the expression two lines later)

8 December 2011

• 01:2301:23, 8 December 2011 diff hist +7‎ Resolution (logic) ‎ →‎A simple example: "In English" doesn't translate well!
• 01:1601:16, 8 December 2011 diff hist −207‎ Resolution (logic) ‎ →‎Resolution rule: simplify complicated paragraph

22 November 2011

• 23:4323:43, 22 November 2011 diff hist +13‎ Parallel port ‎ →‎Uses: English

23 June 2011

• 01:0601:06, 23 June 2011 diff hist +97‎ PDP-11 ‎ →‎Peripherals: slight tweaks; add Wikilinks
• 00:5500:55, 23 June 2011 diff hist +5‎ PDP-11 ‎ improve citation
• 00:5000:50, 23 June 2011 diff hist +233‎ PDP-11 ‎ →‎From third parties: Added Solo, of considerable importance in CS.
• 00:3300:33, 23 June 2011 diff hist +266‎ PDP-11 ‎ →‎Models: Added note about instruction compatibility.
• 00:2700:27, 23 June 2011 diff hist −200‎ PDP-11 ‎ →‎Q-bus models: MINC is adequately covered later and never did fit into this list anyway.
• 00:2300:23, 23 June 2011 diff hist −3‎ PDP-11 ‎ →‎Q-bus models: 22-bit operation was not officially supported for initial PDP-11/23. MINC came out long before Mentec.
• 00:1200:12, 23 June 2011 diff hist +226‎ PDP-11 ‎ →‎Unibus models: There were several never-supported models (e.g. 11/74), no need to mention any of them. 11/44 cache was optional. Removed uninteresting 11/84 picture (took up too much space).

22 June 2011

• 23:3823:38, 22 June 2011 diff hist +11‎ PDP-11 ‎ →‎Decline: The PDP-11 had a more open architecture than the IBM PC! Changed sentence to more relevant issue. Other tweaks.
• 23:1023:10, 22 June 2011 diff hist 0‎ PDP-11 ‎ →‎LSI-11
• 23:0923:09, 22 June 2011 diff hist −388‎ PDP-11 ‎ →‎LSI-11: The LSI-11 chip set was not intended for other uses, so APL implementation irrelevant (and of no historical importance). The only intentional microprogrammed PDP-line product was the 11/60, not based on LSI chipset.
• 23:0623:06, 22 June 2011 diff hist −335‎ PDP-11 ‎ →‎LSI-11: Q-bus aka LSI bus. ODT allows more than just octal input. Streamlined mention of boot disk selection. Reordered memory bus clause. Caching available for Unibus 11/34, 11/44. Core could in principle be used on any Unibus.
• 22:5222:52, 22 June 2011 diff hist −27‎ PDP-11 ‎ →‎No dedicated I/O instructions: Massbus e.g. was not transparent.
• 22:4722:47, 22 June 2011 diff hist −7‎ PDP-11 ‎ PDP-11 was not originally a microprocessor. The VAX didn't replace the PDP-11, but was a more capable follow-on.

20 June 2011

• 23:3423:34, 20 June 2011 diff hist +682‎ Talk:Boolean data type ‎ →‎What about _Bool in C99?
• 23:2623:26, 20 June 2011 diff hist +292‎ Talk:Boolean data type ‎ →‎Enum example - can this work?
• 22:5422:54, 20 June 2011 diff hist −16‎ Boolean data type ‎ →‎History: C99 _Bool (aka bool via <stdbool.h>) is decidedly *not* synonymous with type int.
• 22:4822:48, 20 June 2011 diff hist −10‎ Boolean data type ‎ →‎Implementations: C99 has a Boolean data type, although relational expressions still have type int.
• 22:3222:32, 20 June 2011 diff hist +253‎ Pythagorean addition ‎No edit summary
• 21:5921:59, 20 June 2011 diff hist +344‎ Talk:C99 ‎ →‎Stuff removed from Boolean data type article
• 21:5421:54, 20 June 2011 diff hist +26‎ Talk:C99 ‎ →‎Undefined or Implementation Specific Behavior
• 21:5021:50, 20 June 2011 diff hist +27‎ Talk:C99 ‎ →‎C89 vs C90
• 21:4821:48, 20 June 2011 diff hist −425‎ C99 ‎ →‎Future work: Updated reference to 2007. Added note about major work item. Removed gets() note, as a non-notable detail. Tag: references removed
• 21:4221:42, 20 June 2011 diff hist +80‎ Talk:Sequence point ‎ →‎Problem
• 21:3521:35, 20 June 2011 diff hist +410‎ Sequence point ‎ →‎Examples of ambiguity: Removed beside-the-point sentence. Improved second example.
• 21:0421:04, 20 June 2011 diff hist +4‎ C99 ‎ →‎Implementations: fixed right border of table
• 21:0321:03, 20 June 2011 diff hist −172‎ C99 ‎ Revise second sentence, improving accuracy. Second paragraph was misleading and unnecessary.
• 20:5220:52, 20 June 2011 diff hist −5‎ C99 ‎ →‎Design: "while compiling" was redundant.
• 20:4420:44, 20 June 2011 diff hist +6‎ C99 ‎ →‎Implementations: C99 is a superset, so all C compilers implement most of C99. Restored alphabetical order.
• 20:3220:32, 20 June 2011 diff hist +115‎ C99 ‎ →‎History: Changed "C89 standard" to "1989 standard", which is easier to understand in context. "C99" is used more to refer to the language itself than to the standards document. Clarified what "ANSI standardization process". Etc.

21 May 2011

• 00:3000:30, 21 May 2011 diff hist −582‎ Arbitrary-precision arithmetic ‎ →‎History: streamline
• 00:1800:18, 21 May 2011 diff hist −2,862‎ Arbitrary-precision arithmetic ‎ →‎Example: 1130 is too old to be relevant. Assembly coding is not typically "orders of magnitude" faster. Mention carry bit. Remove editorializing and irrelevancies. Other clarifications.

20 May 2011

• 23:0623:06, 20 May 2011 diff hist −37‎ Arbitrary-precision arithmetic ‎ →‎Applications: clean-ups
• 22:4622:46, 20 May 2011 diff hist −5‎ Arbitrary-precision arithmetic ‎ size in digits was misleading
