1/5/80 ;;Quote: develop a Thesa database bottom-up by writing useful variations of an action

QuoteRef: cbb_1980 ;;1/5/80 I'd like a display for a variable which can be edited with labeled fields.

QuoteRef: cbb_1980 ;;1/6/80 spatial precedence--needed normal form. A+ .. ... +A is left to right precedence A+B is highest precedence

QuoteRef: cbb_1980 ;;1/28/80 board-level Purna, dictionary driven (simplified names), simple assembler producing target machine procedures, simple Purna producing threaded code procedures.

QuoteRef: cbb_1980 ;;2/24/80 note that most programmable controllers are modeled off of relay controllers. These will become obsolete as more complicated control functions are developed.

3/5/80 ;;Quote: for reliable software need to write programs so that obscure bugs don't happen

3/5/80 ;;Quote: include type indicator with literals

4/5/80 ;;Quote: Thesa needs a personal computer; multiple users requires standardization that prevents a consistent interface from client to machine

4/13/80 ;;Quote: for syntactic typing just need 1 type per identifier; two types per id may balance lookup vs. number of procedures

4/13/80 ;;Quote: even though data structure offsets are just addressing functions; want a table-driven representation

4/13/80 ;;Quote: itemids can use hash value with a unique cross bytes

4/18/80 ;;Quote: keep multiuser Thesa database up-to-date with timestamps and ids; avoid central clearing house

4/18/80 ;;Quote: add undefined Thesa instructions to a work queue; when ready, use cross reference to compile its users

4/18/80 ;;Quote: for Thesa a type is just a set of descriptions with a shared name; but the user sees a closely related collection; needs work

4/18/80 ;;Quote: bugs are discovered when they are repetitious; problem of non-recurring bugs such as race conditions

QuoteRef: cbb_1980 ;;4/18/80 "globals should have a saveable state.

4/18/80 ;;Quote: when debugging, want module on screen with inverse video indicating current statement

4/21/80 ;;Quote: Thesa syntax defines certain symbols as operators; scan for match and replace with result; one crack at full match

5/29/80 ;;Quote: a state in a state machine is a unitless number

5/29/80 ;;Quote: mathematics and expression languages are poor models for programming

6/60/80 ;;Quote: an after market in Thesa descriptions could offset its cost

9/15/80 ;;Quote: the true contraction of reference is machine code; a language should be an expansion of reference; unlike VHLLs

10/4/80 ;;Quote: Thesa should be a referred data base; rating system; purchase on a per entry basis

7/7/81 ;;Quote: presenting Echokey took too much time without getting users; maybe sell it inexpensively to end users

11/22/81 ;;Quote: long sequences work fine for words and musical notes but not for communicating computer programs

11/22/81 ;;Quote: Thesa provides an environment where a name is understood in separate languages; computational/numbers and recognition/words

2/1/82 ;;Quote: distinguish information and data; e.g., an employee's salary is data that doesn't need a separate entry; access by a field

6/17/82 ;;Quote: most high level code should be indirect threaded to reduce code size

6/20/82 ;;Quote: first Thesa benchmark was better than existing languages but much worse than assembly code

7/24/82 ;;Quote: Thesa tries to capture the semi-permanent aspect of dictionaries; no word for this kind of information

1/83 ;;Quote: was ITT 1240 influenced by using it for inter-process communication?

QuoteRef: cbb_1980 ;;2/8/83 dubrowM: can't just move people about, need to consider career plans.

QuoteRef: cbb_1980 ;;3/15/83 grimesJD: skip level reviews instituted by Kidd. For example his reports are reviewed by Frame.

QuoteRef: cbb_1980 ;;3/16/83 moodyD: Apple Lisa: "works the way you work". uniform user interface, applications work together, works the way your organization works.

4/13/83 ;;Quote: must specify how information is retired; otherwise it can always effect the future even though out of context

4/13/83 ;;Quote: archived information becomes increasingly difficult to recover the longer it is stored

4/22/83 ;;Quote: to say A happens before B is equivalent to a new thing U whose first tick is A and second tick is B

QuoteRef: cbb_1980 ;;5/10/83 The delete command with a wild-card filename, should show all the matching files and then ask for confirmation. Similar to dired.

4/25/83 ;;Quote: time is activity; the ticking of a clock is the simplest activity; or is time a single tick

3/7/86 ;;Quote: to avoid piracy, sell a service with frequent updates; since most people don't want yesterday's news

11/8/87 ;;Quote: to attack heath problems in developing countries must attack poverty, nutrition, infant mortality and population control; e.g., Korea
