Explanation Component Of Software Systems by Abstract Explanation is an important feature that needs to be integrated into software products
Early software that filled the horizontal software market (such as word processors) contained help systems
More specialized systems, known as expert systems, were developed to produce solutions that required specific domain knowledge of the problem being solved
The expert systems initially produced results that were consistent with the results produced by experts, but the expert systems only mimicked the rules the experts outlined
The decisions provided by expert systems include no justification, thus causing users to doubt the results reported by the system
Software systems need better explanations of how to use them and how they produce results
For explanation systems, the goal is to make some piece of knowledge clear to the user
In horizontal software applications, this explanation will be viewed in the form of intelligent tutoring and help systems that will lead the user through the process of accomplishing their desired results
Expert systems will need to provide justification for their results in a format that the individual user can comprehend, with appropriate facts to convince the user of the validity of their results [, ]
CHI 97: Activity Theory: Basic Concepts and Applications
Introduces activity theory, a conceptual approach that provides a broad framework
for describing the structure, development, and context of computer-supported ...
Fragmentation in the field undermines not only the conceptual integrity of HCI but also its impact on the practice of design, evaluation, and use of computer systems
The Basic Principles of Activity Theory: An Overview Activity Theory is a set of basic principles that constitute a general conceptual system, rather than a highly predictive theory
Integration of the principles These basic principles of Activity Theory should be considered as an integrated system, because they are associated with various aspects of the whole activity
A systematic application of any of these principles makes it eventually necessary to engage all the other ones

If all you intend to do is just write letters using a DOS based word processing program, a 386 or 486 system with a couple megabytes of memory is more than adequate
If you want to be able to surf the Web and play some of the multimedia on-line virtual reality games, then you need a higher-end system, with more memory, more disk space, and a modem or network card to connect to the Internet
If you are looking for a Pentium 4 based system, expect to pay around $800 to $1000 for a good quality system including software and a monitor
You will no doubt see systems advertised for less than this, but there is a good reason why these systems are cheaper and we will discuss this a little later in this document
Don't cut corners on the main system unit (monitor, processor, memory, disk space, etc.)
Remember, this system is going to last you at least 3 or 4 years or more and you don't want to start running out of disk space or memory in the first week that you have it because you trimmed down the amount of memory or got a smaller hard drive so that you could afford to buy 18 different versions of a screen saver program! Remember, you get what you pay for

This course will acquaint students with applications and the logical structure of database management systems and database processing
Discussion of database systems and design of special projects utilizing different query and other high-level programming languages reinforces the theoretical concepts
This course is designed to provide students with an introduction to the organization and architecture of digital computer systems
Teaching the Teachers
Professional development for educators using technology.
The basic sequence includes general computer operations and operating systems
Teachers who already possess a moderate level of computer skills should be given an opportunity to "test out" of the basic training sequence if they can demonstrate a conceptual understanding of the training content and can display the skills necessary to use a computer operating system
Systematic, long-term professional development in technology demands a greater-than-usual commitment on the part of individual teachers, who will need to work many hours above normal district requirements
* Operating systems training: The most commonly used features of Windows 95 and Mac OS operating systems, such as the configuration of desktop screens, background colors, icons, shortcuts, screen savers, driver configurations, file management options, program groups and subgroups, software installation, virus protection, disk scan and defragmentation utilities, CD-ROM applications, sound-card configurations, recycle and trash bins, control panel options, startup program options, program properties and adjustments, use of clipboard and notepad features, and security options

A visitor would clap his hands or speak, and a colorful wave of light would sweep up the tree.) I also built model rockets (this was still the age of Apollo) and through that hobby learned of Micro Instrumentation and Telemetry Systems: MITS (they were selling flashing light kits for night launches of model rockets, but no Altair yet.) Back in 1973 I was an energetic Palo Alto High School student who had recently become a student System Operator for the PAUSD school district's HP2000F 32-user BASIC timeshare computer system (under the direction of Dr
One afternoon I was at the and used one of their ASR 33 teletypes with an acoustical coupler (you actually put the telephone handset into a cradle on the slanted face of the teletype), dialed in, and had an online 'chat' with fellow HP2000F system operator Greg Dolkas (who later went on to work at HP, I understand)
(another student System Operator) and I both attended this first meeting in Gordon French's garage
We were the three youngest ones there, and rather shy and quiet (as I still am today), but were absolutely astounded when Gordon let us step into his house and see his 8008 system using 16K of SHIFT REGISTERS (!) as memory and his very own teletype (unlike random- access memory, his system actually shifted the data in a ring and WAITED until the desired address came up for data read/writes! We were extremely impressed.)
Basic Aspects of Squeak and Smalltalk-80 Programming Language
By Wolfgang Kreutzer. Very nice introduction. Shows how to use Squeak UI and
start programming in Smalltalk. Text, code samples, many screenshots showing what ...
VisualWorks or ) Squeak uses standard Smalltalk syntax and its programming tools and class library are very close to the Smalltalk systems reported in the original series of books
Some links to other tutorial resources: Squeak Contents: Some Basic Building an History & Motivation Smalltalk's roots reach back to the early seventies when manyideas later incorporated into the Smalltalk/ObjectWorks programmingsystem were first explored in the context of the Dynabook project atthe Xerox Palo Alto Research Center (Parc)
Prior to joining Xerox Parc, Alan Kay, themain advocate of this idea, worked at the University of Utah, wherehe was part of a team which developed the Flex programming system, anovel design for a flexible simulation- and graphics-orientedpersonal computer, with many ideas derived from Simula and Sketchpad
For sound reproduction it wasmeant to be plugged into a stereo system, and for access to largeshared data bases there was a connection to telephone lines
The very first Smalltalk system was a thousand lines Basicprogram, which successfully computed 3+4 in October 1972
It wasfollowed by an assembly code implementation which became known as theSmalltalk-72 system two months later
Operating Systems Through Time (8-bits)
A brief history of 8-bit operating systems.
8-Bit Operating Systems This was originally printed in the last issue of, and is reprinted here, with updates, by the author
For example, I mention nothing of mainframe or minicomputer OSes (mostly due to ignorance) and so I should probably call this ' Home Computer Operating Systems Through Time' even though not all of these OSes are purely home computer machines, particularly CP/M
If you have more information about these computer systems, or have info on other systems not mentioned, please mail
A BRIEF HISTORY OF OPERATING SYSTEMS THROUGH TIME by Cameron Kaiser Contrary to popular belief, God did not create the operating system in six days
While some operating systems, like the love-hate Unix, have been around since the early days of digital computing (read 1960's), most have appeared in the late 70's to the present time, varying from powerful multiuser OS's to little OS's that ran on 8 bit computers in under 64K of memory
This is just the briefest portion of operating systems, from then until now
Since computers were a rarity, the question of standardization was ignored, since there were so few computers to be standardized, and consequently the OSes were tied to the capabilities and purposes of each system
A Study of Chinese Writing Systems
Academic paper which examines Chinese orthography .
A Study of Chinese Writing Systems We shall, in this section, focus our energy on Chinese orthography by limiting our endeavor to only one of the six categories of logographs, the phonograms (Wang, 1981)
Logographs are identifying symbols showing a system of relationships between things
There are many existing dictionaries that use index systems employing stroke counts as a means of locating a character
The decomposition to the previously stated definitions of 'material elements' and 'formal elements' of a character, Rankin's system somtimes worked with the 'formal elements, ' and other times with the 'material elements.' This came about because of arbitrariness in interpreting how a modern script should be partitioned
This coding system is based on the meaningful components of a Chinese character
This system, though well designed, is partition-dependent in its coding scheme
For application asw an input code into the keyboard of a computer system, this system would be too time-consuming, inconvenient, and the problem of redundancy too great
However, his idea of a position-independent system is definitely attractive
